Description

Technical Field

[0001] The utility model relates to the field of coal mine transportation equipment, in particular to a mine hydraulic car arrester. Background Art

[0002] A car arrester, also known as a parking device, is one of the important facilities in the coal mine transportation system and belongs to an anti-runaway device. It is usually installed at the upper opening of a slope. On the one hand, it is used to limit the mine car to stay in a specified position. On the other hand, it is used to prevent the runaway from sliding down and avoid major accidents.

[0003] During the process of mine opening and transportation, the safe operation of the mine car is crucial. The existing car arresting devices of mine transportation equipment mostly rely on their own weights to increase the friction between the car arrester and the ground, so as to reduce the phenomenon of backward sliding when arresting the car. However, with the increase in the loading capacity of the locomotive, this car arresting method has problems of inconvenient operation and large limitations, and cannot effectively ensure the stop and normal operation of the mine car in specific situations. There are great potential safety hazards and low car arresting efficiency. Content of the Utility Model

[0004] The utility model provides a mine hydraulic car arrester, aiming to solve the problems of inconvenient operation of the existing car arresting device, inability to effectively ensure the stop and normal operation of the mine car, and great potential safety hazards.

[0005] To achieve its purpose, the utility model adopts the following technical solutions:

[0006] A mine hydraulic car arrester includes a track arranged in a mine cave. The car arrester includes a control part arranged on one side of the track and a car arresting part arranged inside the track. Fixed bars are symmetrically arranged at the bottom of the track. On the fixed bar on the side of the track close to the control part, a fixing plate and a rotator are respectively vertically arranged. An oil pressure telescopic rod is fixedly connected to the fixing plate, and the telescopic end of the oil pressure telescopic rod is connected to the rotator.

[0007] The control part includes an oil tank. An electric oil barrel pump is arranged in the oil tank and is controlled by a control box arranged on its side. The outlet of the electric oil barrel pump is respectively communicated with one end of a first oil pipe and a second oil pipe arranged on the side of the track. The other ends of the first oil pipe and the second oil pipe are both communicated with the oil pressure telescopic rod.

[0008] The car arresting part includes a rotating column arranged between the fixed bars. One end of the rotating column penetrates through the fixed bar and is connected to the rotating shaft of the rotator. A plurality of gear rods parallel to the track are symmetrically arranged on the rotating column, and a gear block is arranged at the bottom of the gear rod.

[0009] Further, a dust-proof frame is arranged around the control part.

[0010] Further, the electric oil barrel pump and the control box are connected through wires and control lines to realize signal transmission.

[0011] Furthermore, the first oil pipe and the second oil pipe are arranged in parallel.

[0012] Furthermore, the spinner and the fixed bar are connected by a flange.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For the car stopper provided by the present utility model, the oil in the fuel tank is transported to the first oil pipe and the second oil pipe through an electric oil barrel pump. When car blocking is required, the control box controls the operation of the electric oil barrel pump. The first oil pipe intakes oil, and the second oil pipe returns oil, thereby pushing the hydraulic pressure telescopic rod to extend and the blocking rod to stand up to achieve the purpose of car blocking; when car blocking is not required, the second oil pipe intakes oil, and the first oil pipe returns oil, thereby assisting the hydraulic pressure telescopic rod to retract and reset, and the blocking rod to lower, and the mine car runs normally, effectively preventing the mine car from getting out of control or accidentally running, ensuring the life safety of the mine tunnel operators and the integrity of the equipment, and reducing the possibility of accidents.

[0015] 2. For the car stopper provided by the present utility model, the fixed plate is provided to provide a supporting force for the hydraulic pressure telescopic rod, and the fixed bar is arranged at the bottom of the track to provide a supporting force for the entire car stopper, ensuring the stability and safety during the car blocking process and not damaging the track. Moreover, the setting of the rotating column and the spinner makes the movement of the blocking rod more flexible and smooth, with strong applicability.

[0016] 3. For the car stopper provided by the present utility model, a dust-proof frame is arranged around the control part to provide protection for key components such as its control box, electric oil barrel pump, and fuel tank against soil and liquid, extending the service life of the device and reducing the maintenance cost.
