Problems solved by technology

[0004] 1. The telescopic arm adopts a three-section telescopic structure. Under the condition of meeting the external dimension requirements of the driving or transportation state of the working platform, it cannot reach the required working height (29.7 meters)
[0005] 2. The chassis has no expansion function. On the one hand, the operating range of the working platform cannot reach the required working range; on the other hand, the chassis occupies a small area and can withstand the small overturning moment of the telescopic arm, which makes the telescopic arm easy to overturn

Embodiment Construction

[0027] see Figure 1~3 , the invention is a straight-arm self-propelled aerial work platform. It mainly consists of counterweight 1, rear balance cylinder 2, telescopic arm 3, slewing platform 4, luffing cylinder 5, drag chain mechanism 6, goose head 7, L-shaped bracket 8, upper operation box 9, working bucket 10 and walking chassis 11 and so on.

[0028] The said slewing platform 4 is arranged on the walking chassis 11 and can turn 360 degrees in any direction.

[0029] The rear end of the telescopic arm 3 is hinged to the slewing platform 4, and the front end is hinged to the goose head 7 through the front balancing oil cylinder. The L-shaped bracket 8 is connected to the goose head 7, and the working bucket 10 is placed on the L-shaped bracket 8. The upper operation box 9 is arranged on one side of the L-shaped support 8 . The drag chain mechanism 6 is relocated on the telescopic arm 3 .

[0030] The rear balance oil cylinder 2 is fixedly connected to the rotary platfo...

Abstract

A self-propelled overhead job platform with straight arm is composed of back balancing cylinder, cc-segment telescopic arm, rotary platform, amplitude changing cylinder, and walking chassis with rising up unit and supporting legs.

Description

Technical field: [0001] The invention relates to an aerial work platform, in particular to a straight-arm self-propelled aerial work platform. Widely used in high-altitude operations in shipbuilding and construction installation industries. It belongs to the technical field of construction machinery. Background technique: [0002] Aerial work platforms are the most widely used in the shipbuilding industry, port machinery manufacturing industry and construction industry, with high frequency of use and fast update cycle. Coupled with the strict requirements of the ship repairing and building cycle, in order to improve production efficiency, the product is used more and more, and the height is getting higher and higher. It is necessary to repair a 200,000-ton bulk carrier and build two 50,000-ton ships. In other words, about 20 aerial work platforms with heights of 21 meters, 25 meters and 28 meters are needed. It can be seen that with the development of the port machinery m...
