摘 要
目前我國許多煤礦礦井已經(jīng)轉(zhuǎn)向中、深部開采,礦井提升設(shè)備作為煤礦的關(guān)鍵設(shè)備,在礦井機械化生產(chǎn)中占有重要地位。制動器是提升機(提升絞車)的重要組成部分之一,直接關(guān)系著提升機設(shè)備的安全運行。多繩摩擦提升機具有體積小、質(zhì)量輕、安全可靠、提升能力強等優(yōu)點,適用于較深的礦井提升。本文針對JK型提升機,對其制動系統(tǒng)進行設(shè)計。在對提升機的制動器選型過程中,因盤式制動器是近年來應(yīng)用較多的一種新型制動器,它以其獨特的優(yōu)點及良好的安全性能被廣大用戶認可,特別是在結(jié)合了液壓系統(tǒng)和PLC 控制之后,液壓系統(tǒng)和PLC 超強的控制性能為盤式制動器的應(yīng)用提供了巨大的工作平臺。制動盤的制動力,靠油缸內(nèi)充入油液而推動活塞來壓縮盤式彈簧來實現(xiàn)。
液壓盤式制動器作為最新一種制動器,具有許多優(yōu)點,所以它在現(xiàn)代多種類型提升機中獲得廣泛的應(yīng)用。它具有制動力大、工作靈活性穩(wěn)定、敏感度高等特點,對生產(chǎn)安全具有重要意義。

Abstract
Currently many of our coal mine has turned to deep mining. Mine coal upgrading equipment as the key equipment holds an important position in mechanized production of the mine. The brakes are one of the important components of a direct bearing on hoistthe safe operation of equipment. Multi-rope friction hoist with small size, light weight, safe, reliable, and strong ability to upgrade apply to the deeper mine hoist. In this paper, the braking system for JK type hoist have been designed. In the hoist brake selection process, because in recent years disc brake is used in the new brakes It's unique strengths and good safety performance recognized by the majority of use。Especially in the light of the hydraulic control system and the PLC, Hydraulic System and PLC super performance of the disc brake provide tremendous platform for the work. Brake disc braking force and rely on the fuel tank filled with oil that drives the piston to compress spring to achieve Disc.
Hydraulic disc brakes as the latest development of a brake, which has many advantages. Therefore it in a modern aircraft types to upgrade gain wider application. It is the braking force, flexibility stability, high sensitivity; on production safety is of great significance.
