Lifting device with dual-purpose rolling-chain wheel

Abstract

The invention discloses a lifting device with a dual-purpose rolling-chain wheel. The lifting device comprises a device body, wherein the device body is mainly composed of a shell body, an operation box, a lifting boom, a telescopic boom, a fixed pulley and a hanging hook, wherein a moving element is arranged on a rotary shaft in a sleeving manner, and a connection rod is hinged at the bottom of the moving element; a slide rod is arranged at the bottom of the shell body, stabilization devices are fixedly connected to the two ends of the shell body, a cylinder is fixedly connected to the top in each stabilization device, an installation frame is connected to the bottom of each cylinder through a piston rod, a suction device is fixedly connected in each installation frame, a suction barrel is fixedly connected to the bottom of each installation frame, a rotary disc is connected to the surface of the top of the shell body through a rotary shaft, and rolling balls are fixedly connected to the bottom of the rotary disc through rolling ball shafts; and the lifting boom is fixedly connected to the surface of the rotary disc, a hydraulic cylinder is fixedly connected to the surface of the shell body, and a connection element is fixedly connected to the tail end of a telescopic rod. The device is high in stability and flexibility, and good in shock absorption effect, and facilitates people to use; and moreover, the device is capable of selecting different moving manners according to terrains during a use process, and convenient to use.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a dual-purpose hoisting device with roller sprockets. Background technique [0002] A crane refers to a multi-action hoisting machine in vertical lifting and horizontal handling within a certain range, also known as a crane. During the lifting process, the crane changes the position of the heavy object, which is convenient for people to use and brings more convenience to people's work. Great convenience, welcomed by people, is an indispensable device in the economic development of our country. [0003] Existing cranes are mainly composed of shells, sprockets, booms and hooks. During the process, the boom needs to change the direction of the heavy objects and needs to be rotated, but the existing boom is rotating The process is mainly controlled by the motor, and the rotation flexibility is not high after long-term use. In addition, the existing cranes are generally divided into two types, ti...

Problems solved by technology

[0003] Existing cranes are mainly composed of shell, sprocket, boom and hook. During the process, the boom needs to change the direction of the heavy object and needs to be rotated. However, the existing boom is rotating The process is mainly controlled by the motor, and the rotation flexibility is not high after long-term use. In addition, the existing cranes are generally divided into two types, tire cranes and sprocket cranes. When the terrain changes, different cranes need to be selected.
