Single-transverse-rail anti-unbalance-loading monorail hoisting system and using method thereof

Abstract

The invention relates to a single-transverse-rail anti-unbalance-loading monorail hoisting system and a using method thereof. Existing monorail hoists cannot be subjected to unbalance loading. Therefore, the anti-unbalance-loading monorail hoisting system comprises a monorail crane walking mechanism and a hoisting box, the hoisting box is fixed below the monorail crane walking mechanism, four corners of the hoisting box are respectively provided with a hydraulic supporting leg and a hydraulic control valve group, inner cavities at the roots of cylinder barrels of the hydraulic supporting legs on the same side are communicated through a high-pressure pipe, and the hydraulic supporting legs on the same side are communicated with the hydraulic control valve group. A transverse rail, an electric transverse pulley and an electric steel wire rope winch are arranged below the hoisting box, the electric transverse pulley and the electric steel wire rope winch are respectively provided with a driving motor, a manipulator, a left hydraulic sensor, a right hydraulic sensor and a PLC (Programmable Logic Controller), a display screen is arranged on the side wall of the hoisting box, and a display screen is arranged below the PLC. And hydraulic values sensed by the left hydraulic sensor and the right hydraulic sensor and a difference value between the two are simultaneously displayed on the display screen. The device is simple in structure, convenient to use, capable of automatically balancing stress and suitable for underground coal mines.

Description

technical field [0001] The invention relates to a single horizontal rail anti-eccentric load monorail hoisting system and a using method thereof. Background technique [0002] The monorail crane is a special I-beam hanging above the roadway as the track, and the suspension vehicles with various functions are connected into a car group, which is pulled by traction equipment and runs along the track. It has strong mobility and high speed. Fast, heavy load, safe and reliable auxiliary transportation equipment driving on the suspension monorail system, mainly used for installation and withdrawal of coal mine fully mechanized mining face. [0003] At present, underground monorail cranes are mostly used to transport equipment and packaged materials, and the effect is good. However, there is a phenomenon of low track utilization rate and long vacant time, and the material cannot be transported horizontally in the roadway. After the equipment and materials are transported to the g...

Problems solved by technology

That is, there are potential safety hazards, which reduce work efficiency and increase the intensity of personnel work

[0004] The track of the existing monorail crane is mainly designed to carry vertical loads. If a heavy object on one side is hoisted, an unbalanced load will be formed, such as figure 1 As shown, it is easy to deform the track

Therefore, in the prior art, the electric wire rope winch carried by the monorail crane can only hoist the heavy objects directly below the track, which is very inconvenient
