Chassis cross lifting type overhead working truck with adjustable platform angle

Abstract

The invention relates to the technical field of overhead working trucks, in particular to a chassis cross lifting type overhead working truck with an adjustable platform angle. The chassis cross lifting type overhead working truck with the adjustable platform angle comprises a frame and a bearing frame arranged on the frame, and an upper assembly formed by sequentially connecting a stand column, a rotating tower, a lower arm, a shaft joint, an upper arm, a telescopic arm and a working bucket is arranged above the bearing frame, wherein two parallel walking mechanisms used for integrally moving the overhead working truck are arranged below the bearing frame, a working bucket overall angle adjusting device used for adjusting the position of the working bucket is arranged at the top end of the telescopic arm, and a cross type expansion lifting device used for connecting the bearing frame and the walking mechanisms is arranged between the bearing frame and the walking mechanisms. Through cooperation of the cross type expansion lifting device and the working bucket overall angle adjusting device, the overhead working truck can be thick, medium and thin, and the overhead working truck is simpler and more convenient to use when working.

Description

technical field [0001] The invention relates to the technical field of aerial work vehicles, in particular to a chassis cross-lifting aerial work vehicle with an adjustable platform angle. Background technique [0002] With the continuous change and development of life and production, aerial work vehicles are more and more widely used in construction, home improvement, electrical work, large-scale cultural and sports venue facilities layout and installation, light rail and bridge construction, and large-scale equipment such as aircraft. Many aspects such as maintenance and cleaning play an increasingly important role. [0003] In order to meet the needs of production and life, the structure of aerial work vehicles is required to be continuously developed and innovated. As far as the current self-propelled forms of aerial work vehicles are concerned, the existing wheeled self-propelled vehicles are heavy and have a large pressure on the ground. The ground cannot bear it, and...

AI Technical Summary

Problems solved by technology

[0007] When using general aerial work equipment and aerial work, there are still the following deficiencies: 1. Regardless of whether the existing aerial work platform is a mobile aerial work platform, a spider aerial work platform, a self-propelled aerial work platform, or a scissor aerial work platform Work platform, it is difficult to adjust the work platform within the range after the support arm is fixed, which cannot meet the needs of multi-angle and multi-dimensional operations

When there is a change in the working position, it is necessary to adjust the position of the support arm to achieve the position adjustment of the aerial work platform to achieve the purpose of precise operation in the designated work area; even if the change in the working position is small, it is necessary to adjust the position of the support arm to achieve it. Flexible, resulting in poor quality work and low work efficiency

2. The existing aerial work platform reaches the designated operation area through the overall lifting and moving of the lifting arm. The use is extremely inflexible and the operation efficiency is low.

[0009] The above-mentioned invention improves the leveling method of the working bucket, but the leveling structure is cumbersome, and it cannot fail to solve the technical problem that when the working area needs to be lifted in a small range and the height of the change is reduced, it also needs to be realized by the overall improvement of the lifting arm , the working platform cannot be adaptively adjusted in the horizontal and vertical directions, and the adjustment method is not flexible enough to meet the flexibility needs of aerial work vehicles in daily construction
