Multifunctional aerial working platform

Abstract

The invention relates to a multifunctional aerial working platform. The multifunctional aerial working platform comprises a chassis, a rotating platform, a cantilever crane, a man-carrying device, an electric control system and a hydraulic system, wherein the cantilever crane comprises a main cantilever, an intermediate cantilever, a small cantilever and a flying cantilever; the intermediate cantilever sleeves the small cantilever, and the main cantilever sleeves the intermediate cantilever; the front end of the small cantilever is connected to the flying cantilever, and the front end of the flying cantilever is connected to the man-carrying device. According to the multifunctional aerial working platform, a steel wire rope is conveniently dismounted; the degree of tightness of the steel wire rope can be detected in real time; a man-carrying platform can be weighted; meanwhile, the cost of a hydraulic pipeline can be decreased.

Description

technical field [0001] The invention relates to a multifunctional aerial work platform. Background technique [0002] When working on the surface of high-risk objects such as ships and buildings, scaffolding was used in the past, and workers climbed up to work layer by layer. However, this method is not only inefficient, but the quality cannot be guaranteed. Because there are many dead ends in the erection of scaffolding, it is impossible to The operation is completed at one time, the operation time is long, the operation cost is high, and the risk is extremely high. There are frequent fatal accidents in erecting and working on scaffolding. [0003] Therefore, aerial work platforms have emerged to assist workers in high-risk operations. This kind of aerial work platform drives the manned platform to lift through the expansion and contraction of the boom, so that workers can easily work at high places. However, the previous multifunctional aerial work platforms have the foll...

Problems solved by technology

[0004] 1. There is a steel wire rope in the mother arm of the aerial work platform. After a certain period of use, the steel wire rope needs to be disassembled for inspection or oiled. However, in the past, one end of the steel wire rope in the aerial work platform is fixed on the mother arm, and the other end is fixed on the forearm. , the telescopic movement of the boom is performed through the pulley and the telescopic oil cylinder installed on the middle arm. The wire rope needs to be disassembled together with the boom. It is very inconvenient to disassemble and the disassembly efficiency is low.

[0005] 2. The female boom in the aerial work platform is the fixed end of the steel wire rope. The boom frame performs telescopic movement through the joint action of the telescopic oil cylinder, pulley and steel wire rope. However, the telescopic steel wire rope may become loose after long-term use, and the wire rope cannot be found in time. has come loose, posing a safety hazard to workers

[0006] 3. The aerial work platform drives the manned platform to go up and down through the lifting of the flying arm, and drives the manned platform to turn through the rotating cylinder. However, the previous flying arms are equipped with two sets of hydraulic pipelines to control the lifting and turning of the manned platform respectively. , the two sets of hydraulic pipelines need to be set from the front end of the boom to the front end of the fly boom, and the layout of the hydraulic pipelines is relatively long, so the two sets of long pipeline layouts need to consume more cost

[0007] 4. The manned platforms in aerial work platforms all have a certain upper limit of load weight, but the usual manned platforms do not have a weighing function, and once overloaded, it is easy to be dangerous
