Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mine cars, in particular to a mine car with a scissor lifting carriage. BACKGROUND

[0002] A mine car is a special vehicle used for transporting materials such as ore, sand, etc. in mines or other industrial sites. It is usually composed of one or more carriages and runs along fixed tracks. Mine cars are usually driven by electric motors or internal combustion engines, can carry a large amount of materials, and can transport on slopes. The design and manufacture of mine cars need to consider the special requirements of the mine environment, such as the slope of the slope, the carrying capacity of the vehicle, the stability of the vehicle, etc. At the same time, mine cars also need to have certain safety protection devices, such as braking systems, protective barriers, etc., to ensure the safety of vehicle operation.

[0003] At present, mine cars are narrow-gauge railway transport vehicles for transporting coal, ore and waste rock and other bulk materials in mines. The mine car body will produce a certain vibration during travel, which will aggravate the collision and wear between various parts on the mine car. In severe cases, it may cause the connecting pin on the mine car to pop out, causing a runaway accident. In order to avoid a runaway accident, shock-absorbing measures must be taken for the mine car and track transportation system.

[0004] At present, the existing mine car equipment usually uses shock-absorbing springs for shock absorption, but the overall shock-absorbing capacity is poor, and the overall protection and buffering capacity is insufficient.
