矿井巷道内的跑车会对生产安全造成极大威胁,如何防止跑车事故的发生是保障斜井运输安全的一个重要研究课题。传统的捕车装置多采用直接卡死矿车碰头或车身的方式完成,这种捕车方式容易造成矿车的倾翻或脱轨。文中提出了一种能够抱紧矿车后轴的新型缓冲捕车器结构,并从使用条件、设计原理、理论计算3个方面对该捕车器进行了研究。最后制造出一台捕车器样机,并搭建了一个坡度为15°的试验场地,分别在变坡点及距离变坡点5,10,15 m的位置对单节矿车进行了跑车试验,对跑车速度、阻尼器压缩量、阻尼楔块的偏移量进行了测量,试验验证了该捕车器的有效性,试验结果为后续捕车器的改进提供了依据。
How to prevent the occurrence of sports car accident is an important research topic to ensure the safety of inclined shaft transportation. Traditionally used car snatching devices directly stuck with the car or head to complete the way, this car is easy to cause the car dumping or derailment. This paper presents a new type of buffer car retainer that can hold the rear axle of the tub and studies the car retainer from the aspects of service conditions, design principles and theoretical calculations. Finally, a prototype of a car-trap was built and a test site with a gradient of 15 ° was set up. A sports car test was carried out on the single-section tub at the positions of 5,10 and 15 m, The speed of the sports car, the amount of damping of the damper and the displacement of the damping wedge were measured. The validity of the car was verified by the test. The test results provided the basis for the improvement of the car catcher.
