Multifunctional aerial work platform car

Abstract

The invention provides a multifunctional aerial work platform car, and belongs to the technical field of aerial work devices. The platform truck comprises a frame, a support arm assembly and a working platform assembly which are arranged on a chassis walking system, the frame comprises a front frame and a rear frame, a box body is arranged on the front frame, one end of the support arm assembly is connected with the box body, and the other end of the support arm assembly is connected with the working platform assembly; the support arm assembly comprises a support arm seat arranged on the box body, a support arm and a support arm oil cylinder, wherein one end of the support arm is hinged with the support arm seat, the other end of the support arm is hinged with the fixed end of the follow-up oil cylinder, the fixed end of the support arm oil cylinder is hinged with the support arm seat, the output end of the support arm oil cylinder is hinged with the support arm, and the output end of the follow-up oil cylinder is hinged with the follow-up seat; the support arm oil cylinder and the follow-up oil cylinder form a hydraulic translation mechanism; and a working platform assembly is arranged on the follow-up seat. According to the multifunctional aerial work platform car, the work speed can be increased, the labor efficiency can be improved, the mechanical construction level of a tunnel is improved, and particularly the safety of tunnel construction is improved.

Description

technical field [0001] The invention relates to the technical field of aerial work devices, in particular to a multifunctional aerial work platform vehicle. Background technique [0002] At present, in the tunnel excavation operation in my country, the charging operation mainly relies on workers standing on the bench to carry out the charging operation, and the bench is bulky, which is troublesome to carry every time, time-consuming and labor-intensive, and low efficiency, and there are too many workers on the working surface , generally requires about 8 to 12 people, and the safety factor is low. In order to improve the operation speed and labor efficiency, improve the level of tunnel mechanized construction, especially improve the safety of tunnel construction, aerial work platform vehicles are developed for this purpose. SUMMARY OF THE INVENTION [0003] In view of this, in order to solve the current tunnel excavation operation, the charging operation mainly relies on w...
