Connecting device with buffering effect for coal mine transport vehicle

Abstract

The invention relates to a connecting device with a buffering effect for a coal mine transport vehicle. The connecting device with the buffering effect for the coal mine transport vehicle comprises aconnecting mechanism, two fixed plates and at least two auxiliary mechanisms, wherein the two fixed plates are arranged in parallel and opposite to each other; the connecting mechanism and the auxiliary mechanisms are arranged between the two fixed plates; the connecting mechanism comprises two connecting plates, two universal devices and at least two connecting assemblies; and each connecting assembly comprises a transmission rod, a first spring and two fixed blocks. The auxiliary mechanisms are in one-to-one correspondence with the transmission rods; each auxiliary mechanism comprises a connecting line and two auxiliary assemblies, wherein the two auxiliary assemblies are separately arranged at two ends of the connecting line; and the auxiliary assemblies are in one-to-one correspondencewith the fixed plates. The connecting device with the buffering effect for the coal mine transport vehicle achieves the buffering and vibration reduction effects through the connecting mechanism, sothat the coal mine in mine cars is prevented from falling off the mine cars, not only that, but also the disconnection of the two mine cars is prevented through the auxiliary mechanisms, and the reliability is improved.

Description

technical field [0001] The invention relates to the field of coal mine mining equipment, in particular to a connection device with a buffer effect for a coal mine transport vehicle. Background technique [0002] A mine car is a common type of coal mining equipment. A mine car is a narrow-gauge railway vehicle for transporting coal ore in a coal mine. Generally, it must be pulled by a locomotive or a winch. The mine car is divided into fixed mine cars, Tipper mine car, single-side curved track side dump mine car, bottom dump mine car and shuttle mine car. [0003] During the use of the existing mine cars, most of the two mine cars are connected through the connecting device, but the connecting device will produce fatigue damage after long-term use. When the connecting device is damaged, the mine connected to the connecting device will be damaged. If the car is separated, it is easy to cause a collision. In severe cases, it will cause the mine car to overturn, which reduces t...

[0003] During the use of the existing mine cars, most of the two mine cars are connected through the connecting device, but the connecting device will produce fatigue damage after long-term use. When the connecting device is damaged, the mine connected to the connecting device will be damaged. If the car is separated, it is easy to cause a collision. In severe cases, it will cause the mine car to overturn, which reduces the reliability. Not only that, most of the existing connecting devices have no buffer function. When the mine car brakes suddenly for some reason, it is easy to make the mine The coal in the car will fall from the mine car under the action of inertia, and at the same time, the mine car may be damaged by rigid impact
