Problems solved by technology
[0002] The existing spider-type aerial work vehicle generally has a heavy chassis, which increases the weight of the whole vehicle. The boom used is a quadrangle, which is weaker in bending resistance than the pentagon, and the human body during use. Hands will be held on the upper guardrail, and it will be easy to pinch the hand when encountering a vertical wall when rotating the platform rail

Embodiment Construction
[0008] The present invention will be described in detail below with reference to the accompanying drawings. As shown in the drawings, the structure of the present invention includes a working platform column 1, a telescopic boom frame 2, a fully automatic telescopic roller 3, a lifting cylinder 4, a turret 5, a push rod 6, chassis legs 7, steering wheels 8, chassis 9. The driving wheel 10 is characterized in that the telescopic boom 2 is composed of five-section skeletons, and the five-section skeletons that make up the telescopic boom 2 are all made of steel pentagonal rectangular tubes. The adjacent telescopic booms The 2 are connected with each other by chains. Each telescopic boom 2 has a sprocket shaft at a fixed position, and each sprocket shaft is fixed by a balance lock pin to prevent the sprocket shaft from rotating when the chain is moving. The telescopic boom The top of the 2 is provided with a working platform column 1, the size of the upper guardrail circle of the...

The invention relates to a spider type straight-arm high-altitude operating platform. The spider type straight-arm high-altitude operating platform is characterized in that a telescopic boom rack is formed by combining five sections of frameworks, wherein the five sections of frameworks forming the telescopic boom rack are steel pentagonal rectangular tubes; every two adjacent sections of the telescopic boom rack are engaged with each other by a chain; a working platform fenceis arranged at the top end of the telescopic boom rack; the enclosure area of an upper protective guardrail of the working platformfence is smaller than that of a lower protective guardrail of the working platform fence; a full-automatic telescopic roller is arranged at the outer side of the telescopic boom rack; the bottom end of the telescopic boom rack is arranged on a rotary tower; a swing mechanism is arranged in the rotary tower; under the driving of the rotary tower, the telescopic boom rack can swing by 360 degrees; one end of a jacking oil cylinder is fixedly connected with the telescopic boom rack; the other end of the jacking oil cylinder is fixedly connected with the rotary tower; a push rod is arranged at the rear side of the rotary tower; a chassis is arranged below the rotary tower; and drive wheels and steering wheels are arranged at the front and back portions of the lower part of the chassis. The light high-altitude operating equipment disclosed by the invention enables indoor and outdoor operation to be very convenient, does not occupy a too large position and a too large space, and has price advantage.
Description
technical field [0001] The invention relates to the engineering machinery industry, in particular to a spider type straight-arm high-altitude operation platform, which is applied to high-altitude operations. Background technique [0002] The existing spider-type aerial work vehicle generally has a heavy chassis, which increases the weight of the whole vehicle. The boom used is a quadrangle, which is weaker in bending resistance than the pentagon, and the human body during use. Hands will be held on the upper guardrail, and it will be easy to pinch the hand when encountering a vertical wall when rotating the platform rail. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a spider-type straight-arm type aerial work platform. The technical solution adopted by the present invention to solve the technical problem is: the structure of the present invention includes a workin...
