Scissor aerial work platform with front drive and front steering

Abstract

The invention relates to a front-drive front-steering scissors type aerial work platform, which comprises a driving chassis and a lifting device. The driving chassis comprises a chassis body and a driving device; the driving device comprises a left wheel carrier, a right wheel carrier, a linkage carrier and a steering oil cylinder; the left wheel carrier and the right wheel carrier are rotatably arranged on the chassis body through wheel carrier shafts; two ends of the linkage carrier are respectively hinged onto the left wheel carrier and the right wheel carrier; one end of the steering oil cylinder is arranged on the linkage carrier; the other end of the steering oil cylinder is fixedly connected with one wheel carrier shaft through an installation plate. According to the front-drive front-steering scissors type aerial work platform provided by the invention, a front-drive front-steering arrangement scheme is adopted, so that the chassis is simplified, and meanwhile, the flexibility in steering is improved; a potentionmeter is also adopted, and is arranged on a shaft of the lifting device, and any lifting height corresponds to an only rotation angle of a rotary shaft, so that the potentionmeter presents an only resistance value; the resistance values in one-to-one correspondence to the heights are recorded in a controller, so that the lifting height of the lifting device is limited through setting the resistance value.

Description

technical field [0001] The invention relates to the technical field of lifting platforms, in particular to a scissor type aerial work platform. Background technique [0002] Aerial work platform Aerial work platform is a mobile high-altitude operation product that serves various industries such as aerial work, equipment installation, and maintenance. The related products of aerial work platforms mainly include: scissor type, mast type, straight arm type, articulating arm type, telescopic type, mast type, guide frame climbing type, etc. [0003] The scissor type aerial work platform has high stability, wide operating platform and high carrying capacity, which makes the aerial work scope larger and suitable for multiple people to work at the same time. It makes aerial work more efficient and safer. This product integrates four-wheel movement and two-wheel traction. It uses the chassis of automobiles, tricycles or battery cars as the platform chassis, and uses the vehicle's e...

AI Technical Summary

Problems solved by technology

[0004] Existing scissor-type aerial work platforms are large in size and cannot be well adapted to various occasions

If the existing scissor-type aerial work platform is reduced, many problems will be encountered, such as the setting of the steering. The original steering mechanism is difficult to adapt to the reduced version of the scissor-type aerial work platform due to its large size and complex structure.
