[0002] Coal mine vehicles, also known as mine cars, can be used to transport staff, goods, materials, etc. The most important thing is to transport coal and waste rock in mines. Mine cars need to run on mine tracks and need to be towed by locomotives or winches. Multiple mine cars need to be connected in a row on the track and then towed by locomotives or winches.
[0003] However, due to the special environment of mines, the tracks are not flat enough, and the mine environment is messy and difficult to manage. When the mine cars are running on the tracks, they will produce large vibrations. After long-term use, the vibrations will cause the connections between adjacent mine cars to loosen, and even cause damage to the connecting parts, which will cause rows of mine cars to disconnect or derail. Moreover, if there are breaks or gaps somewhere on the track, it will cause the mine cars to vibrate violently or bump when running on the track. Due to the long track, it is not easy for the mine environment to detect breaks and gaps in the track in time, so the transportation safety of the mine cars cannot be effectively managed.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0024] Embodiment 1
[0025] like Figure 1 , Figure 2 , Figure 3 and 6As shown, a vehicle management device for underground coal mines comprises a track 1, on which mine cars 2 arranged opposite to each other are arranged, and the mine cars 2 on both sides are connected together by connecting components, and also comprises component one and component two, on which a mounting plate 4 is fixedly connected, component one comprises a fixing box 3 fixedly connected to the mounting plate 4, a GPS module 6 and a vibration monitor 5 located above the mounting plate 4 are arranged in the fixing box 3, a wireless data transmission module 7 electrically connected to the vibration monitor 5 and the GPS module 6 is arranged in the fixing box 3, and an antenna 8 electrically connected to the wireless data transmission module 7 is arranged at the upper end of the fixing box 3.
[0026] Through the above structure, the vibration frequency of the mine car 2 can be monitored during operation, and abnormal vibration frequency data and position data can be sent. How to promptly notify the management personnel when the connection components are disconnected, the specific structure is as follows:
[0027] like Figure 1 , Figure 4 , Figure 5 and 6 As shown, component two includes relatively arranged fixed cylinders 9 respectively installed on the mine cars 2 on both sides, the fixed box 3 and the fixed cylinder 9 are connected with the mine car 2 by bolt threads, the fixed cylinders 9 on both sides are provided with travel grooves 12, the travel grooves 12 are slidably provided with pulling blocks 11, a connecting rope 10 is provided between the pulling blocks 11 on both sides, the connecting rope 10 is a steel wire rope, and sliders 13 are fixedly connected to both sides of the pulling block 11, the fixed cylinder 9 is provided with slide grooves 14 cooperating with the sliders 13 on both sides of the travel groove 12, the slide grooves 14 are provided with buttons 16, the inner walls of the slide grooves 14 are provided with springs 15 arranged around the button 16 and connected to the sliders 13, the fixed cylinder 9 is provided with a control module 17 electrically connected to the wireless data transmission module 7, and the mine car 2 is provided with a mobile power supply cooperating with the GPS module 6, the vibration monitor 5, the wireless data transmission module 7, the control module 17 and the antenna 8.
