Telescopic connection assembly and aerial work platform

Abstract

The invention relates to the field of engineering machinery, in particular to an engineering working vehicle and more particularly to a telescopic connection assembly and an aerial work platform. The telescopic connection assembly is used for connecting a telescopic transmission assembly on the aerial work platform with an operation table telescopically and comprises an outer arm, an inner arm slidably arranged in the outer arm and capable of extending out from one end of the outer arm, and a small arm telescopic oil cylinder arranged between the outer arm and the inner arm. Therefore, the telescopic connection assembly has large horizontal extending distance so that the operation table can extend to a farther area on the horizontal plane, and thus the wok range of the aerial work platform is enlarged. In addition, the telescopic connection assembly has high structure strength and structure stability, and the usage safety of the aerial work platform can be improved greatly.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of engineering machinery, in particular to an engineering operation vehicle, and more particularly to a telescopic connection assembly and an aerial work platform. [0003] 【Background technique】 [0004] Aerial work platform is an advanced aerial work machine, which can greatly improve the work efficiency, safety and comfort of aerial construction personnel, and reduce labor intensity. It has been widely used in developed countries. The use of aerial work platforms in my country is becoming more and more extensive, such as the initial general municipal street lamp maintenance, garden tree pruning, etc., and with the rapid development of my country's economy, engineering construction, industrial installation, equipment maintenance, plant maintenance, shipbuilding, Electricity, municipal administration, airports, communications, gardens, transportation, etc. have a growing demand for aerial work platforms.

Problems solved by technology

[0005] The forearm connecting the console and the main arm (which can be a telescopic connection component) in the traditional aerial work platform adopts a parallelogram structure. The two connection points on the top) are hinged by two connecting arms, and the connection line of the two connection points on the console is parallel to the connection line of the two connection points on the forearm head, so that the two connection arms and the two connection points on the console The connection line of the arm and the connection line of the two connection points on the forearm head form a parallelogram, and then match the luffing oil cylinder and leveling oil cylinder and other components to make the arm have the functions of luffing and leveling; because the existing arm uses The most important is the parallelogram structure, so that its horizontal extension is limited by the length of the connecting arm and cannot meet the working requirements for a large horizontal extension; in addition, the parallelogram arm structure makes the aerial work platform within the working area. Relatively poor flexibility
