Aerial work platform with high-stability steering running function

Abstract

The invention relates to an aerial work platform with a high-stability steering running function. The aerial work platform comprises a running base plate and a lifting device, wherein the running base plate comprises a base plate, a running device, a pit protection mechanism and supporting leg structures, wherein the running device comprises a left steering wheel, a right steering wheel, a left wheel carrier, a right wheel carrier, a linkage rack, a steering cylinder and a steering curved slab; each supporting leg structure comprises a trolley frame board, a supporting leg seat board, a supporting leg mounting board, a supporting outer tube, a supporting inner tube and a supporting foot; and the lifting device comprises a scissor-fork lifting structure and a working platform, and the working platform comprises a platform fixing baseplate, a handrail rack and a handrail door. According to the aerial work platform, not only is the linkage structure simplified, but also the steering stability and the steering synchronicity are improved; and the handrail door of the working platform is convenient to open and can effectively prevent accidental looseness, so that the security of the working platform is high.

Description

technical field [0001] The invention relates to a high-altitude work platform with a high-stability driving steering function. Background technique [0002] Aerial work platform is a product that serves mobile high-altitude operations such as aerial work, equipment installation, and maintenance in various industries. The related products of aerial work platforms mainly include: scissor-type aerial work platforms, vehicle-mounted aerial work platforms, articulating-arm aerial work platforms, self-propelled aerial work platforms, aluminum alloy aerial work platforms, and cylinder-type aerial work platforms. [0003] During the operation of the aerial work platform, the platform operation requires high mobile flexibility. The steering structure of the existing driving wheel has poor stability and synchronization during the steering process, and the rotation angle is limited, which affects the user experience.

AI Technical Summary

Problems solved by technology

[0003] During the operation of the aerial work platform, the platform operation requires high mobile flexibility. The steering structure of the existing driving wheel has poor stability and synchronization during the steering process, and the rotation angle is limited, which affects the user experience.

[0004] The existing structure of the aerial work platform usually installs support plates on both sides of the base to achieve the stability of high-altitude operations, which can play a supporting role in the process of tire height imbalance. It is a fixed installation structure, and the support plate will have a certain negative impact on the walking performance of the tire

[0005] In order to ensure the stability of the platform when working at heights, it is necessary to provide more stable support for the work platform through the outrigger structure. However, the installation of the existing outrigger structure is relatively complicated, resulting in low assembly efficiency and resulting in maintenance. The process of removing the outriggers is more complicated

[0006] In order to ensure the safety of the operators on the working platform, a railing door needs to be installed at the entrance of the working platform. The opening of the existing railing door lock is relatively complicated, which causes great inconvenience when the operator climbs the ladder to enter the working platform
