High-stability aerial work platform driving chassis

Abstract

The invention relates to a high-stability aerial work platform driving chassis which comprises a chassis body, a driving device, a pit protection mechanism and a support leg structure. The driving device comprises a left steering wheel, a right steering wheel, a left wheel frame, a right wheel frame, a linkage frame, a steering cylinder and a steering bend plate; the pit protection mechanism comprises a left pit plate, a right pit plate, two first pit connecting plates, two second pit connecting plates, two third pit connecting plates, a fourth pit connecting plate, two movable seats, two guide shafts, two limit plates and two movable seat press springs; the support leg structure comprises a frame plate, a support leg plate, a support leg mounting plate, an outer support pipe, an inner support pipe and a support leg. By the above structure, the pit plates can rotate flexibly to meet requirements of different states, throughout performance is improved, steering angle limit can be increased, and use performance is enhanced.

Description

technical field [0001] The invention relates to a driving chassis of a high-altitude work platform with high stability. Background technique [0002] Aerial work platform (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. At present, there are mainly defects in the following aspects of 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,...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the aerial work platform, the platform operation requires high mobility 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] 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

[0005] 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
