Embodiment Construction

[0016] The support structure of the active arm frame for aerial work of the present invention is as follows: figure 1 As shown, it mainly includes a main frame 1, an outer balance bar 5, an inner balance bar 7, an auxiliary beam 10 and a telescopic arm 11. The main frame 1 is welded on the slewing support plate 16. During the working process, the main frame 1 and the slewing support plate 16 rotate together with the slewing support 17 on the chassis of the aerial work vehicle (or platform). The lower end of the outer balance bar 5 is hinged with the main frame 1 through the pin shaft 2 to form a rotatable connection. The inside of the outer balance bar 5 is covered with an inner balance bar 7 to form a telescopic structure. The outer balance bar 5 and the inner balance bar 7 are hollow rods with a rectangular cross section. The sliding block of the guide function (marked at the end of the figure). When the inner balance bar 7 and the outer balance bar 5 are in the stowed sta...

Abstract

The invention provides a bracing structure of a high-altitude work movable arm support. The bracing structure comprises a main frame, an outer balancing pole, an inner balancing pole, an auxiliary frame and a telescopic arm, wherein the lower end of the outer balancing pole is hinged with the main frame through a pin shaft; the inner balancing pole is sleeved in the outer balancing pole; one end of the telescopic arm, one end of the auxiliary frame and the outer end of the inner balancing pole are hinged with one another through arm support pin shafts; the other end of the auxiliary frame is hinged with the main frame; a variable-amplitude hydraulic cylinder is arranged on the auxiliary frame; a piston rod of the variable-amplitude hydraulic cylinder is hinged with the telescopic arm; an arm support pin shaft variable-amplitude oil cylinder is connected between the pin shaft for hinging the lower end of the outer balancing pole with the main frame and the arm support pin shaft; and the main frame, the auxiliary frame and the arm support pin shaft variable-amplitude oil cylinder form a triangular structure. The bracing structure can reduce the collection height of the high-altitude work movable arm support when guaranteeing the same work height and increase the work height when guaranteeing the same collection height, has the characteristics of simple structure, high flexibility and reliable performance, and is compact and rational and convenient to control.

Description

technical field [0001] The invention relates to a movable boom support structure used for transporting workers and working equipment to a designated height for operation in construction machinery equipment, and belongs to the technical field of high-altitude operation machinery. Background technique [0002] There are many types of aerial work equipment products, each with its own characteristics. It started relatively early in foreign countries, and has formed a very large industry, and established an international organization (TC214). Domestic aerial work vehicles (platforms) basically rely on imports, and there are not many self-developed ones. At present, the boom support points of most aerial work vehicles (platforms) are fixed, so the structure is simple, but their maximum operating height and storage height are fixed, and the requirements of aerial work vehicles (platforms) are met While the working height is high, the storage height is minimized, which is conv...
