Hydraulic lift for disassembling and assembling large arm of high-altitude operation device

Abstract

The invention discloses a hydraulic lift for disassembling and assembling a large arm of a high-altitude operation device. The hydraulic lift for disassembling and assembling the large arm of the high-altitude operation device comprises a base, four inclined struts, a hydraulic oil cylinder, two outer side supports, two inner side supports and a supporting main beam; the lower ends of the four inclined struts are fixedly connected with the base; the lower end of a cylinder barrel of the hydraulic oil cylinder is fixedly connected with the upper ends of the four inclined struts; the lower ends of the two outer side supports are fixedly connected with the two sides of the base correspondingly; the lower ends of the two inner side supports are inserted into the two outer side supports correspondingly; the two ends of the supporting main beam are fixedly connected with the upper ends of the two inner side supports correspondingly; and the middle portion of the supporting main beam is fixedly connected with a piston rod of the hydraulic oil cylinder. The hydraulic lift for disassembling and assembling the large arm of the high-altitude operation device is applicable to various high-altitude operation devices, for example, the hydraulic self-locking supporting device function is achieved when a straight arm type high-altitude operation car, a curved arm type high-altitude operation car, a hydraulic crane and the like are maintained, and the beneficial effects that supporting is stable, the safety performance is high, movement is convenient and connection is fast are achieved.

Description

technical field [0001] The invention relates to the technical field of engineering hydraulic lifts, in particular to a large arm disassembly hydraulic lift. Background technique [0002] A hydraulic lift is a liftable machine equipment composed of a walking mechanism, a hydraulic mechanism, an electric control mechanism, and a supporting mechanism. The hydraulic oil is under a certain pressure formed by the vane pump, and enters the lower end of the hydraulic cylinder through the oil filter, explosion-proof electromagnetic reversing valve, throttle valve, hydraulic control check valve, and balance valve, so that the piston of the hydraulic cylinder moves upward to lift the weight. The oil returned from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic reversing valve, and its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge.

Problems solved by technology

However, when some industrial high-altitude equipment needs maintenance, such as the maintenance of straight-arm aerial work vehicles, articulated-arm aerial work vehicles, and hydraulic cranes, ordinary hydraulic lifts cannot adapt to their functions such as hydraulic self-locking and supporting equipment.
