Buffering connector for tramcars

Abstract

The invention provides a buffering connector for tramcars, relates to the field of tramcar connectors, and concretely relates to the buffering connector for the tramcars. The buffering connector for the tramcars can prevent the rigid collision of the tramcars, and has a double buffering function. The buffering connector for the tramcars comprises a hydraulic cylinder, an oil storage tank, a buffering spring, a spring pressure plate, a lock nut, a plug connection end and a one-way throttle valve. A rod chamber of the hydraulic cylinder directly communicates with the oil storage tank. By arranging an oil return passage, the rod cavity of the hydraulic cylinder and a rodless cavity of the hydraulic cylinder communicate with each other. The one-way throttle valve is arranged in the oil returnpassage. The one-way throttle direction is: flowing into the rod cavity of the hydraulic cylinder from the rodless cavity of the hydraulic cylinder. The buffering spring sleeves a piston rod of the hydraulic cylinder. The buffering connector for the tramcars has a good anti-collision effect and can effectively prevent collision deformation of the tramcars.

Description

technical field [0001] The invention relates to the field of mine car connectors, in particular to a mine car buffer connector. Background technique [0002] In the field of mining, rail mine cars are used as the main equipment for transporting minerals. In the production process, in order to meet the needs of production, the mine carts are generally connected to the mine carts through connectors, and the traction equipment is connected to the mine carts through wire ropes to control the mine carts to move back and forth on the mine track. To complete the transportation of personnel, ore, etc. The traditional connector is a chain connector, and the connection is completed by cooperating with the pin, which does not have the function of buffering impact. Because the traditional rail transport mine car is composed of wheels and mine car body, it does not have a braking device. When the mine car goes up and downhill or stops, the speed of the front and rear mine cars will be ...

AI Technical Summary

Problems solved by technology

Because the traditional rail transport mine car is composed of wheels and mine car body, it does not have a braking device. When the mine car goes up and downhill or stops, the speed of the front and rear mine cars will be inconsistent, and collisions between the mine cars are easy to occur. With the traditional connector connection, the collision force between mine carts is not absorbed by the buffer, and a rigid collision occurs directly between mine carts

Especially when the mine cart is fully loaded, the collision between the mine carts will easily lead to the deformation, rollover and damage of the mine cart, which will increase the cost of production and maintenance
