An underground lane-changing hydraulic lifting crane and its lane-changing method

Abstract

The invention discloses an underground variable-lane hydraulic lifting crane and a lane-changing method thereof. The crane comprises: a chassis and a lifting mechanism arranged on the chassis; Curve direction change mechanism, the right angle curve direction change mechanism is arranged under the chassis, the right angle curve direction change mechanism includes longitudinal travel wheels and lateral travel wheels, and the longitudinal travel wheels and lateral travel wheels are both arranged on the chassis through a lifting structure below. The structure design of the underground variable track hydraulic lifting crane is reasonable, and the roof of multiple supporting mechanisms is stable and reliable, and the position can be adjusted according to the requirements of the curve direction change, and the lower curve direction change mechanism can be used to realize the right-angle curve direction change operation. Narrow down the limitations of use; the double drive mechanism can provide greater torque required for the operation and improve the stability of hoisting.

Description

technical field [0001] The invention relates to the technical field of underground lifting 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 hoisting and hoisting work is still done by manpower with the hoisting mechanism, which will not only have great labor intensity and low work efficiency, but also have certain safety risks. It is narrow and the lifting equipment on the ground cannot work underground; although there are underground lifting equipment, but for the heavy objects of several tons or even dozens of tons, there will be insufficient hoisting rotation torque, poor hoisting stability, and encountering curves. There are disadvantages such as inability to perform steering and other poor effects, so an underground hydraulic lifting crane that can replace manpower, enhance hoisting stability, and can turn at right angles is required. ...

AI Technical Summary

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
