A current receiver lifting shoe mechanism

Abstract

A lifting boot mechanism of a current collector includes a long boot handle and a short boot handle hinged to the long boot handle, wherein the long boot handle and the short boot handle are both rotatable about a hinge point in a plane formed by a centerline of the long boot handle and a centerline of the short boot handle to push and pull the current collector to contact or disconnect the carbonslider of the current collector from the third rail. The long boot handle and the short boot handle are rotatable in a plane formed by a centerline of the long boot handle and a centerline of the short boot handle. Compared with the existing boot-removing handle, the mechanism adopts the joint-type handle structure, which increases the effective force arm when the boot-removing, so that the operator can save more labor. The mechanism can realize the operation of lifting boots or lowering boots by the operator in the whole process, and avoid the operator from protruding out of the vehicle to carry out the operation, thereby greatly improving the operation safety. The mechanism cleverly takes the short shoe-off handle as the part of the long shoe-off handle, which can reduce the storage space. When the mechanism is to be dismounted when the boot is manually lifted, only the short boot handle is operated.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a collector lifting shoe mechanism. Background technique [0002] The current collector, also known as the current collector shoe, is installed on the side frame of the bogie of the vehicle. During the operation of the train, the carbon slider is contacted with the third rail by the force of the spring to obtain electric energy, and the electric energy is provided to the train through the cable. Realize the power supply of the whole train. Such as figure 1 and figure 2 As shown, by controlling the rotation of the transmission rod 6 of the current collector, the contact or disconnection between the carbon slider and the third rail 7 can be controlled, so as to realize shoe lowering or shoe raising. [0003] The current collectors currently used in the market can be divided into manual and pneumatic according to the driving mode of the lifting shoe. The lowering shoe of t...

AI Technical Summary

Problems solved by technology

When lowering the boots on the car, the operator must stick his body out of the car body more before using the handle to lower the boots, which has potential safety hazards; the current design requires a long handle for lowering the boots on the car, which cannot be used under the car, so The long boot handle and the short boot handle need to be used separately to take off the boots under the car
