Amplitude angle adjustable mast drive type cross shear fork lifting mechanism

Abstract

The invention discloses an amplitude angle adjustable mast drive type cross shear fork lifting mechanism. The amplitude angle adjustable mast drive type cross shear fork lifting mechanism comprises across shear fork mechanism, a masts drive mechanism, an angle adjusting mechanism and a supporting board; the cross shear fork mechanism comprises a plurality of shear fork modules sequentially spliced; each shear fork module comprises a plurality of inner connection rods and a plurality of outer connection rods; the inner connection rods and the outer connection rods correspond to one another oneby one and are crossed and hinged correspondingly; the angle adjusting mechanism can achieve adjustment of the amplitude angle of the cross shear fork mechanism through switching of connection of bearings; and the mast drive mechanism is a telescopic rod arranged between the adjacent angle adjusting mechanisms and can drive the cross shear fork mechanism to ascend or descend and improve the bearing capacity. The lifting mechanism of the structure has the advantages of being adjustable in amplitude angle, low in weight and large in bearing capacity, and meets the lifting requirements of large-bearing high-altitude operation on narrow entrances and areas with complex environments.

Description

technical field [0001] The invention relates to the field of lifting equipment, in particular to a mast-driven cross-scissor lifting mechanism with adjustable argument angle. Background technique [0002] Many large modern factories have some large equipment such as boilers, etc. After long-term use of these equipment, failures such as equipment aging often occur, resulting in huge economic losses. Therefore, most large equipment needs regular safety inspections to minimize economic losses. loss; however, the internal detection area of ​​large-scale equipment is usually narrow in space, the environment is complex, and most of them are located at high altitudes, so the detection is very difficult. Accidents, resulting in automated high-altitude detection equipment. Automatic testing equipment mainly uses lifting platforms and climbing methods to work; most of the more common lifting mechanisms weigh several hundred kilograms, which greatly limits their scope of use; in addit...
