我矿在斜井提升运输中,使用一种鱼尾叉式简易挡车器。挡车器主要由联接环、器身、鱼尾叉三部分组成,见图1。空车下行时,将挡车器放在空矿车运行方向的前部第一个车厢里。提升时,用插销将挡车器的联接环与尾部的插销孔联在一起,挡车器与提升矿车一起前进,如图2。我矿自使用鱼尾叉式挡车器以来,曾避免了两起断绳的跑车事故。下面仅举一例。掘进三队在付井提升一辆矸石车(付井的倾斜角度为21°40′,斜长173米,使用 JD I mine in the inclined shaft to enhance transport, the use of a fish tail fork simple stopper. Stopper mainly by the coupling ring, body, fish tails three parts, shown in Figure 1. Empty car down, the stopper on the empty car running direction of the first car in the front. Ascending, the latch will be linked with the stopper block and the tail of the tail hole pin linked together, stop car and enhance the car with the forward, shown in Figure 2. Mine mine since the use of fish tail fork block has been avoided two broken rope sports car accident. Here’s just one example. Excavation of the three teams in the well to raise a gangue truck (pay the inclination angle of 21 ° 40 ’, inclined 173 meters, the use of JD
