Conical vibration absorber of mine vehicle

Abstract

The present invention relates to a conical vibration damper for mine car. It includes the following several portions: metal case shell, electric conductive rubber layer and metal neck bush. The electric conductive rubber layer is placed between metal case shell and metal neck bush. The upper end of the described metal case shell is equipped with upwards flange and its lower end is equipped with downwards flange, its middle portion is made into the form of conical face. The metal neck bush is made into the form of funnel. Said metal case shell, electric conductive rubber layer and metal neck bush are connected into one body. Said vibration damper can be used between the compartment and chassis.

Description

technical field [0001] The invention relates to a component of a mine vehicle, in particular to a shock absorber of a mine vehicle. Background technique [0002] During the mining process, vehicles must be used to transport maintenance equipment and personnel, including engineering rescue. At present, "small train" transport vehicles are used. During the operation of this type of transport vehicle, electric sparks are easily generated between the carriages and between the metal rollers and the guide rails due to the impact between each other, thereby causing underground tiles. wire explosion, endangering the lives of miners, in order to overcome this fatal defect, anti-static underground transport vehicles are being developed abroad, which includes chassis 3, compartment 4, conductive rubber wheels 2 and shock absorbers 1, conductive rubber wheels 2 are installed on the chassis 3, the compartment 4 is installed on the chassis 3 through the shock absorber 1. This shock absor...

At present, "small train" transport vehicles are used. During the operation of this type of transport vehicle, electric sparks are easily generated between the carriages and between the metal rollers and the guide rails due to the impact between each other, thereby causing underground tiles. wire explosion, endangering the lives of miners, in order to overcome this fatal defect, anti-static underground transport vehicles are being developed abroad, which includes chassis 3, compartment 4, conductive rubber wheels 2 and shock absorbers 1, conductive rubber wheels 2 are installed on the chassis 3, the compartment 4 is installed on the chassis 3 through the shock absorber 1. This shock absorber 1 must not only have excellent electrical conductivity, but also be able to withstand greater pressure, and must also be able to absorb the gap between the compartment and the chassis to the greatest extent.
