Composite driving hoisting device

Abstract

The invention discloses a composite driving hoisting device. The driving hoisting device is characterized in that the device comprises a base; the base is provided with a rotating shaft used for connecting a mechanical driving device with a hoisting frame, and a mechanical driving device and a hydraulic oil cylinder used for respectively driving the rotating shaft to rotate; the rotating shaft comprises a constraint main shaft; the constraint main shaft is provided with a bearing seat and a mounting plate; the bearing seat is connected with the mechanical driving device through a rotating plate, and the mounting plate is connected with the hoisting frame; the output end of the hydraulic oil cylinder retracts or stretches to drive the rotating shaft to rotate, or the mechanical driving device drives the bearing seat on the rotating shaft to rotate around the constraint main shaft; and the outer end of the hoisting frame rises or lowers along with the bearing seat. According to the driving hoisting device, heavy object lifting in a complex environment is achieved by adopting a composite driving mode and a design structure thereof; mechanical and hydraulic driving are cooperatively used under a control system; lifting of larger heavy object can be completed in a limited structure space; the structure is simple; the disassembly and assembly are convenient; and conversion from composite driving to single driving can be easily achieved.

Description

technical field [0001] The invention relates to a compound driving lifting device, which belongs to the technical field of crane equipment. Background technique [0002] A crane is a mechanical device that lifts and transports heavy objects within a certain range. With the rapid development of industrial technology and economy, it plays a vital role in reducing labor intensity, saving labor costs and improving production efficiency. Construction cranes generally include tire cranes, crawler cranes, tower cranes and bridge cranes, etc., which are suitable for different occasions according to different tasks. The working performance of the crane is largely determined by the driving device, and the different driving methods will directly determine its operating environment and service life. [0003] At present, the mainstream driving methods include mechanical drive and hydraulic drive. Most products choose a single centralized drive mode. Typical hoist cranes are driven by ...
