Hole protecting mechanism of aerial work vehicle

Abstract

The invention discloses a hole protecting mechanism of an aerial work vehicle. The hole protecting mechanism structurally comprises a car bottom guiding plate, a pressing shaft, a protection mechanismbody, a traction swing mechanism, a limit fixing ring buckle, a linkage movable plate, a pit support protection plate and a balance pressure stabilization detection device, the lower surface of the car bottom guiding plate is connected with the upper surface of the protection mechanism body through an electric welding mode, the pressing shaft is installed on the left surface of the protection mechanism body in an embedded mode, the pressing shaft penetrates through the upper end and the lower end of the limiting fixing ring buckle and is connected with the same axis through an attaching mode,the right surface of the limiting fixing ring buckle is connected with the left surface of the protection mechanism body in an electric welding mode. According to the hole protecting mechanism, whensupporting is carried out, the protection plate is subjected to force application balance by applying the connection pressure through the hydraulic pressure, so that the deformation of the plate surface is prevented from being unbalanced, the ultrasonic waves are arranged in the pressure applying plate to carry out detection imaging on the protection plate in a sound wave manner, so that the situation that the detection needs to be disassembled is avoided, and the maintenance and replacement can be timely known.

Description

technical field [0001] The invention relates to the technical field of high-altitude operation, more precisely, it relates to a pothole protection mechanism for an aerial work vehicle. Background technique [0002] Aerial work is an operation in which people carry out construction at a high place that is vertical to the ground as a reference. Aerial work is generally performed on high-voltage wires, high-rise buildings, etc., and the work platform truck is used to transport workers upwards for construction. vehicle. However, the current pothole protection device has the following disadvantages: [0003] 1. When the aerial work vehicle is affected by potholes, the supporting protective plate on the equipment is in contact with the ground and stretched, and when the protective plate touches the ground, it is easy to cause the upper end to lose force and press the plate to deform the protective plate, and the deformed plate is stressed. Unevenness affects the balance protecti...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a pothole protection mechanism for aerial work vehicles to solve the problem that when the aerial work vehicles in the prior art are affected by potholes, the support protection plate on the equipment contacts the ground and stretches apart. When the protective plate touches the ground, it is easy to cause the upper end to lose force and exert pressure on the plate to deform the protective plate. The deformed plate is unevenly stressed and affects the balance protection of the aerial work vehicle. Wear and tear, it is difficult to detect in time when using the protection plate, making the protection plate’s bearing force reach the upper limit and it is easy to break
