[0002] The rail type coal feeding trolley, also known as a mine car, is a narrow - gauge railway handling vehicle used in mines to transport bulk materials such as coal, ore, and waste rock. The power cord of the traditional two - stage gas generator bunker rail type coal feeding trolley uses a steel wire rope as the hanging point of the power cord to tow a common cable. Since the length of the steel wire rope is about 150 meters, due to the principle of thermal expansion and contraction, and the weight of the cable of nearly 300 meters being towed, the steel wire rope and the cable in the middle position sag severely, and even the problem of the cable rubbing against the ground and wearing the insulating layer of the cable occurs. In addition, the fixing method of the cable and the steel wire rope uses binding wire. During the back - and - forth movement of the rail trolley, the binding wire will cause damage to the insulating layer of the cable, posing a potential safety hazard of electric leakage.

[0025] Such as Figure 3 and Figure 4As shown in the figure, a threaded rod 18 is provided inside the fixed rod 17, and a threaded tube 19 is provided inside the first push rod 16. The left end of the threaded rod 18 penetrates through the first push rod 16 and is threadedly connected to the first push rod 16.
