Lifting device with aloft work function based on hydraulic parallel expansion

Abstract

The invention discloses a lifting device with an aloft work function based on hydraulic parallel expansion. The lifting device structurally comprises a base, a supporting vertical rod, a telescopic rod, a bearing rod and a lifting device, wherein a left turning wheel and a right turning wheel are respectively fit to and located on the front and back of the bearing rod, and meanwhile the left turning wheel is of a rotatable structure, so that the resistance of movement and the force of friction are reduced, and further the impact shaking caused when a support roller device moves is reduced; even if a loading operation box suffers wind power to shake aloft, the bearing rod is stable as far as possible under the action of the front and back clamping of the left turning wheel and the right turning wheel; a receiving plate is forced to rise; a right rotating frame is forced to rotate anticlockwise by taking the left end of a supporting hanging rod as a base point, meanwhile a left rotatingframe rotates clockwise by taking the right end of the supporting hanging rod as a base point; grooves in the left rotating frame and the right rotating frame are used for preventing the loading operation box from shaking, and meanwhile claws on the left rotating frame and right rotating frame are bent at an angle; two expansion bearing devices are used for reinforcing the loading operation box, so that the force bearing points of the loading operation box are at four corners, the stability is greatly improved, and the inclination caused by uneven force is avoided.

Description

technical field [0001] The invention is a hoisting device with high-altitude operation function based on hydraulic parallel expansion, which belongs to the field of high-altitude operation tools. Background technique [0002] Due to the development of science and technology, high-rise buildings in today's cities stand tall. At this time, the transformation and simple update of the outer wall of the building need aerial work tools to realize. Generally, hoisting equipment with the function of aerial work that can be lifted is used. The existing hoisting equipment is supporting The one-way wheel structure adopted in the roller device is firmly connected due to the downward force under the action of gravity, but it is easy to shake if there is a lateral force. [0003] However, the existing hoisting equipment with the function of working at heights has the following disadvantages: [0004] 1. The one-way wheel structure adopted on the support roller device, if there is a later...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a hoisting device with high-altitude operation function based on hydraulic parallel expansion, so as to solve the problem of the one-way runner structure adopted on the supporting roller device. If there is a lateral force At this time, such as the wind in the high altitude outside, it is easy to make the shaking load-carrying operation box violently shake. The structure often adopts a single hook structure. Since there is only a single point of support, if the force on the four corners of the load-carrying operation box is uneven, it is prone to tilting. Violent shaking of the loading operation box, endangering the operator
