Underground lane-changing hydraulic hoisting crane and lane-changing method thereof

Abstract

The invention discloses an underground lane-changing hydraulic hoisting crane and a lane-changing method thereof. The crane comprises a chassis, a hoisting mechanism arranged on the chassis, supporting and jacking mechanisms detachably arranged on the chassis, and a right-angle curve turning mechanism arranged below the chassis, wherein the right-angle curve turning mechanism comprises longitudinal traveling wheels and transverse traveling wheels, and the longitudinal traveling wheels and the transverse traveling wheels are arranged below the chassis through lifting structures. The undergroundlane-changing hydraulic hoisting crane is reasonable in structural design, the multiple supporting and jacking mechanisms support and jack stably and reliably, the position can be adjusted accordingto the curve turning requirement, right-angle curve turning operation is achieved in cooperation with the lower curve turning mechanism, and the use limitation is reduced; and a dual-drive mechanism can provide larger torque required by operation, so that the hoisting stability is improved.

Description

technical field [0001] The invention relates to the technical field of underground hoisting equipment, in particular to an underground variable lane hydraulic lifting crane and a lane changing method thereof. Background technique [0002] At present, most of the underground lifting work is still completed by manpower with the lifting mechanism, which will not only have a high labor intensity and low work efficiency, but also have certain safety risks. The hoisting equipment on the ground is too small to work underground; although there are underground hoisting equipment, for heavy objects of several tons or even dozens of tons underground, the hoisting rotation torque is insufficient, the hoisting stability is poor, and when encountering curves There are disadvantages such as inability to turn and other poor effects. Therefore, there is a need for an underground hydraulic lifting crane that can replace manpower, enhance hoisting stability, and can turn at right angles. [0...

Problems solved by technology

[0002] At present, most of the underground lifting work is still completed by manpower with the lifting mechanism, which will not only have a high labor intensity and low work efficiency, but also have certain safety risks. The hoisting equipment on the ground is too small to work underground; although there are underground hoisting equipment, for heavy objects of several tons or even dozens of tons underground, the hoisting rotation torque is insufficient, the hoisting stability is poor, and when encountering curves There are disadvantages such as inability to turn and other poor effects, so an underground hydraulic lifting crane that can replace manpower, enhance hoisting stability, and can turn at right angles is needed

[0003] For example, in Chinese patent 201220673418.5, two support hydraulic cylinders are used to support the top point, and each support hydraulic cylinder has only one support point on the top. When the lifting object is heavy, the two support points do not It must be able to provide high security and stability, and it cannot meet the requirements of changing lanes; in Chinese patent 201220241711.4, the slewing drive uses a rotary hydraulic cylinder, which will cause unstable movement when lifting and transferring heavy objects. The phenomenon of heavy objects swinging, causing unsafe factors

In both patents, neither can change lanes, which greatly reduces their application range in the well
