Description
技术领域 technical field
本实用新型涉及煤矿升降机技术领域，具体是一种新型煤矿升降机的液压系统。 The utility model relates to the technical field of coal mine elevators, in particular to a hydraulic system of a novel coal mine elevator.
背景技术 Background technique
在煤矿井下作业生产中，升降机广泛用于人员、工具以及材料等的运送。升降机的运输安全性严重制约着生产的效率，尽管采用曳引式升降技术已经十分成熟，但应用此技术的升降机在环境恶劣的采矿现场，技术安全性能大打折扣，不能可靠地防止安全坠落问题，给作业人员的生命安全带来严重的隐患。 In the production of underground coal mine operations, elevators are widely used for the transportation of personnel, tools and materials. The transportation safety of the elevator seriously restricts the production efficiency. Although the traction-type lifting technology is very mature, the elevator using this technology has a greatly reduced technical safety performance in the harsh mining site, and cannot reliably prevent the safety of falling. Serious hidden dangers are brought to the life safety of operating personnel.
现煤矿用的升降机主要是利用曳引技术，曳引升降作为垂直运送人员及物料的提升机械，主要包括导轨架、吊笼、起升机构和附墙机构等。吊笼是完成运送任务的执行机构，其运行安全性直接关系到运送的人和物。升降机构的安全系统在露天作业时容易失灵，不能有效防止吊笼坠落。这严重影响了煤矿的安全生产以及生产效率的提高，采用新的技术提高升降机的安全作业成为亟待解决的问题。 The elevators used in coal mines mainly use traction technology, and the traction lift is used as a lifting machine for vertically transporting personnel and materials, mainly including guide rail frames, hanging cages, lifting mechanisms and wall-attached mechanisms. The cage is the executive mechanism to complete the transportation task, and its operation safety is directly related to the transported people and objects. The safety system of the lifting mechanism is prone to failure when working in the open air, and cannot effectively prevent the cage from falling. This has seriously affected the safe production of coal mines and the improvement of production efficiency, and the adoption of new technologies to improve the safe operation of elevators has become an urgent problem to be solved.
