Expressway guardrail cleaning device

Abstract

The invention discloses an expressway guardrail cleaning device which comprises a connecting support, a reversing arm, a steering arm, a connecting bar component, a spring, a sweeper and a sweeper support assembly, a swing cylinder, a swing cylinder seat, a lifting cylinder, and a four bar mechanism formed by the connecting bar component, the steering arm and the sweeper support assembly. The middle of the swing cylinder seat is groove-shaped and provided with a connecting block inside. The connecting block is fixed with one end of a guide shaft. The other end of the guide shaft penetrates through a guide hole in the groove-shaped bottom of the swing cylinder seat. The other end of the guide shaft is provided with a limit adjusting nut. The spring, a compression spring, is arranged on the guide shaft and arranged between the connecting block and the groove-shaped bottom of the swing cylinder seat. The swing cylinder seat is arranged on the reversing arm. A piston of the swing cylinder is hinged with the reversing arm. The expressway guardrail cleaning device is convenient to operate and capable of adjusting vertical position of the sweeper and prolonging service life of the spring.

Description

technical field [0001] The invention relates to an expressway guardrail cleaning device. Background technique [0002] An existing highway guardrail cleaning device includes a connecting bracket, a rocker arm, a work frame and a sweeping brush. Rod and nozzle, the working frame is installed on the rocker arm and can rotate around it, and the sweeping brush is installed on the working frame and can move around the axis of the working frame. In order to realize the avoidance function, a spring is provided between the working frame and the rocker arm of the guardrail cleaning device. In the above-mentioned guardrail cleaning device, when the working frame is at a certain working angle around the rocker arm, it is necessary to manually insert the movable pin into the corresponding pin hole provided between the working frame and the rocking arm, so that the working frame and the rocker arm The rocker arm maintains this working angle, so the operation is troublesome. Since the ...

AI Technical Summary

Problems solved by technology

In the above-mentioned guardrail cleaning device, when the working frame is at a certain working angle around the rocker arm, it is necessary to manually insert the movable pin into the corresponding pin hole provided between the working frame and the rocking arm, so that the working frame and the rocker arm The rocker arm maintains this working angle, so the operation is troublesome

Since the position of the sweeping brush cannot be adjusted in the up and down direction, it is difficult to adapt to cleaning guardrails of different heights

At the same time, because the spring provided between the working frame and the rocker arm is on its outer side, it is easy to be rusted and damaged by water in the working environment of cleaning the guardrail.

When the working frame is retracted, the spring is in the maximum stretch state for a long time, which is easy to cause fatigue damage and shorten the service life
