Chain and hopper The chain chain for steel welding. The hopper is fixed on the joint of the chain. Different height of the bucket lift machine is set the corresponding number of chains, connectors, and hopper. multi-function Multi function hoist is a kind of electric hoist can be used in the ground and air. It is widely used in the construction industry. It has large conveying capacity, high altitude, stable and reliable operation. Multifunctional electric hoist rated lifting weight of 500 kg / 300 kilograms, multi-functional electric hoist the maximum lifting height of 100 meters, multifunctional electric lifting machine 500 kilograms improve (run) speed 5.5m/min; 300 kilograms of ascension (run) speed 8m / min, Rated up to 500KG, 300KG; The maximum lifting height: 100M The lifting speed is: 5.5M/MIN, 8M/MIN; Motor power is not as follows: 1.5kw, 1KW, 1.5KW, 0.4KW; The use of power supply: single phase and three-phase two. Classification of multi function elevator: Multi function lifting machine is divided into DTS-30 multi-function elevator and DTS-50 multi function DTS50-80-A, DTS50-80-B, DTS30-80-A, DTS30-80-B Other varieties HL type ring chain machine The HL type ring chain centrifugal bucket elevator is composed of a moving part (a hopper and a traction chain), an upper section with a transmission chain wheel, a lower section with a tension wheel, a middle casing and a driving device. Installation and maintenance Machine maintenance is a very important regular work, it should work closely with the operation and maintenance, and should have full-time personnel on duty check. Bearing All the load bearing 1. Crusher assume a machine, so good lubrication on bearing life have great relationship. It directly affects the machine life and the operation rate, therefore require the injection of a lubricating oil must be clean, seal must be in good condition and main oiling the machine of a rotating bearing, roller bearing the all gear and bearing, sliding plane. 2 the installation of the new tyre must be examined often prone to loose. 3 pay attention to the work of each part of the machine is normal. 4 pay attention to check the wear degree of easy to wear parts, always pay attention to replace worn parts. 5. The plane of the bottom of movable device, should go out dust and other matter lest machine can not meet the broken material bearing activities can not on the underframe mobile, resulting in serious accidents. 6 increase the bearing oil temperature, should stop and check the reason to be eliminated. 7 when the rotation of the gear in operation if there is an impact sound should be immediately stopped to check and eliminate. Installation commissioning 1 the equipment should be installed in the level of concrete foundation, fixed with anchor bolts. 2 attention should be paid to the installation of the vertical and horizontal. 3 after installation, check the various parts of bolt loosening and fastening the host whether the door please fasten. 4 power line and control switch according to the power of equipment. 5 inspection is completed, the empty load test, the normal test can be carried out. Safety regulation 1 the hoisting machine is maintained and managed by the designated personnel. The key of the power switch box is managed by the designated personnel. 2. Improve the machine must have a hoisting limiter and a stroke limiter, limiter should make the pulley in ascension to distance the drum or pulley 300mm before can automatically stop. Action sensitive and reliable, and carry out test. 3 hoist should have the maximum load mark, in the lifting, the weight of the landing is not overload (1T). 4 after power, check the hoisting limiter, stroke limiter, interlock switch safety device 5 lifting, before landing, alarm warning, can drive. 6 lifting machines will not allow manned on the next. 7 after the work is finished, the hoisting machine hanging plate should be born, and then cut off the power supply, close up and down the fence door. 8 to maintain the health of the surrounding environment. matters needing attention 1 empty load driving. So every time before the machine should be discharged in all the hopper of the material, and then stop. 2 can not be reversed. Reverse the chain derailment that may occur, to eliminate the trouble of derailment. 3 uniform feeding. The sudden increase of the volume of feed ban. The feeding amount can not exceed the capacity of lifting and conveying machine. Otherwise, it is easy to cause the bottom of the accumulation of serious "stuffy car" accident. 4 timely and proper amount of lubricating oil. 5 the chain and the hopper should be replaced in a timely manner when severe wear or damage. fault analysis fault To enhance the head wheel and the bottom wheel shaft mounting is not likely to cause the hopper belt deviation, main forms: the head wheel and the bottom wheel transmission shaft in the same vertical plane and is not parallel; two driving shafts are installed in a horizontal position and in the same vertical plane; the two transmission axis parallel and in the same vertical plane and horizontal. Such a situation, the hopper belt deviation, easy to cause the hopper and barrel hit, hopper with tear. In addition, the head of the hoist can bear large dynamic pressure, the maximum amount of up to 100 tons, due to the long operation of the inevitable in the bearing wear. Traditional methods to repair welding or brush plating machine repair, but both of them are some drawbacks: repair welding of high temperature of the thermal stress can not be completely eliminated, easy to cause material injury, leading to bend or break components; and brush plating coating thickness, is easy to peel and the above two methods are with repair of metal metal, can not change the "hard to hard" with the relationship between, in under the influence of the force, still caused by wear again. In view of the above problems, the main use of the United States and Europe is the polymer composite material repair method, which is the most mature application of the United States is the world's blue technology. Polymer material has strong adhesion, excellent comprehensive mechanical properties, can remove free machining. Both gradated welding thermal stress effects, repair thickness is not restricted, and products with the metal material does not have the deformability, absorption increased the impact of machine vibration, avoid wear again possible, and greatly extend the service life of the parts of the equipment, for the enterprise to save a large amount of downtime, create enormous economic value.

是一種大型提升機械設(shè)備。由電機帶動機械設(shè)備，以帶動鋼絲繩從而帶動容器在井筒中升降，完成輸送任務(wù)。礦井提升機是由原始的提水工具逐步發(fā)展演變而來。現(xiàn)代的礦井提升機提升量大，速度高，安全性高，已發(fā)展成為電子計算機控制的全自動重型礦山機械。 礦井提升機主要由電動機、減速器、卷筒（或摩擦輪）、制動系統(tǒng)、深度指示系統(tǒng)、測速限速系統(tǒng)和操縱系統(tǒng)等組成，采用交流或直流電機驅(qū)動。按提升鋼絲繩的工作原理分纏繞式礦井提升機和摩擦式礦井提升機。纏繞式礦井提升機有單卷筒和雙卷筒兩種，鋼絲繩在卷筒上的纏繞方式與一般絞車類似。單筒大多只有一根鋼絲繩，連接一個容器。雙筒的每個卷筒各配一根鋼絲繩，連接兩個容器，運轉(zhuǎn)時一個容器上升，另一個容器下降。纏繞式礦井提升機大多用于年產(chǎn)量在120萬噸以下、井深小于400米的礦井中。摩擦式礦井提升機的提升繩搭掛在摩擦輪上，利用與摩擦輪襯墊的摩擦力使容器上升。提升繩的兩端各連接一個容器，或一端連接容器，另一端連接平衡重。摩擦式礦井提升機根據(jù)布置方式分為塔式摩擦式礦井提升機（機房設(shè)在井筒頂部塔架上）和落地摩擦式礦井提升機（機房直接設(shè)在地面上）兩種。按提升繩的數(shù)量又分為單繩摩擦式礦井提升機和多繩摩擦式礦井提升機。后者的優(yōu)點是：可采用較細的鋼絲繩和直徑較小的摩擦輪，從而機組尺寸小，便于制造；速度高、提升能力大、安全性好。年產(chǎn)120萬噸以上、井深小于2100米的豎井大多采用這種提升機。 纏繞式提升機 單繩纏繞式提升機 根據(jù)卷筒數(shù)目可分為單卷筒和雙卷筒兩種：①單卷筒提升機，一般作單鉤提升。鋼絲繩的一端固定在卷筒上，另一端繞過天輪與提升容器相連；卷筒轉(zhuǎn)動時，鋼絲繩向卷筒上纏繞或放出，帶動提升容器升降。②雙卷筒提升機，作雙鉤提升。兩根鋼絲繩各固定在一個卷筒上,分別從卷筒上、下方引出,卷筒轉(zhuǎn)動時，一個提升容器上升，另一個容器下降。纏繞式提升機按卷筒的外形又分為等直徑提升機和變直徑提升機兩種。等直徑卷筒的結(jié)構(gòu)簡單，制造容易，價格低，得到普遍應(yīng)用。深井提升時，由于兩側(cè)鋼絲繩長度變化大，力矩很不平衡。早期采用變直徑提升機（圓柱圓錐形卷筒），現(xiàn)多采用尾繩平衡。 纏繞式提升機的主要部件有主軸、卷筒、主軸承、調(diào)繩離合器、減速器、深度指示器和制動器等。雙卷筒提升機的卷筒與主軸固接者稱固定卷筒，經(jīng)調(diào)繩離合器與主軸相連者稱活動卷筒。中國制造的卷筒直徑為 2～5m。隨著礦井深度和產(chǎn)量的加大，鋼絲繩的長度和直徑相應(yīng)增加。因而卷筒的直徑和寬度也要增大，故不適用于深井提升。 多繩纏繞式提升機 提升機在超深井運行中，尾繩懸垂長度變化大，提升鋼絲繩承受很大交變應(yīng)力，影響鋼絲繩壽命；尾繩在井筒中還易扭轉(zhuǎn)，妨礙工作。20世紀 50年代末，英國人布雷爾（Blair）設(shè)計了一臺直徑3.2m雙繩多層纏繞式提升機(又稱布雷爾式提升機)，提升高度1580～2349m，一次提升量10～20t。 摩擦式提升機 1938年，瑞典的ASEA公司在拉維爾（Laver）礦安裝了一臺直徑1.96m雙繩摩擦式提升機。1947年德國G.H.H.公司在漢諾威（Hannover）礦安裝了一臺四繩摩擦式提升機。多繩摩擦式提升機具有安全性高、鋼絲繩直徑細、主導(dǎo)輪直徑小、設(shè)備重量輕、耗電少、價格便宜等優(yōu)點，發(fā)展很快。除用于深立井提升外，還可用于淺立井和斜井提升。鋼絲繩搭放在提升機的主導(dǎo)輪（摩擦輪）上，兩端懸掛提升容器或一端掛平衡重(錘)。運轉(zhuǎn)時，借主導(dǎo)輪的摩擦襯墊與鋼絲繩間的摩擦力,帶動鋼絲繩完成容器的升降。鋼絲繩一般為2～10根。 井塔式提升機 機房設(shè)在井塔頂層，與井塔合成一體，節(jié)省場地；鋼絲繩不暴露在露天，不受雨雪的侵蝕，但井塔的重量大，基建時間長，造價高，并不宜用于地震區(qū)。 落地式提升機 機房直接設(shè)在地面上，井架低，投資小，抗震性能好；缺點是鋼絲繩暴露在露天，彎曲次數(shù)多,影響鋼絲繩的工作條件及使用壽命。 多繩摩擦式提升機的主要部件有主軸、主導(dǎo)輪、主軸承、車槽裝置、減速器、深度指示器、制動裝置及導(dǎo)向輪等。主導(dǎo)輪表面裝有帶繩槽的摩擦襯墊。襯墊應(yīng)具有較高的摩擦系數(shù)和耐磨、耐壓性能,其材質(zhì)的優(yōu)劣直接影響提升機的生產(chǎn)能力、工作安全性及應(yīng)用范圍。使用較多的襯墊材料有聚氯乙烯或聚氨基甲酸乙酯橡膠等。由于鋼絲繩與主導(dǎo)輪襯墊間不可避免的蠕動和滑動，停車時深度指示器偏離零位，故應(yīng)設(shè)自動調(diào)零裝置，在每次停車期間使指針自動指向零位。車槽裝置用于車削繩槽，保持直徑一致，有利于每根鋼絲繩張力均勻。為了減少震動，可采用彈簧機座減速器。 內(nèi)裝式提升機 內(nèi)裝式摩擦提升機是將工作機和驅(qū)動機合二為一且融合微電子技術(shù)、信息技術(shù)的機電一體化整體，其特點是將電動機裝在卷筒或摩擦輪內(nèi)部。這種一體化的機電整體，既是工作機，又是驅(qū)動機。此外，作為電動機來看，也與傳統(tǒng)構(gòu)造不同，不是定子在外，轉(zhuǎn)子在內(nèi)，而是恰恰相反。它從根本上改變了提升機的構(gòu)造概念。 內(nèi)裝式提升機早在1988年就開始生產(chǎn)，世
