[0002] Monorail crane, as a kind of equipment used for underground transportation in coal mines, has the following advantages: simple operation, strong mobility, high flexibility, fast running speed, high safety and reliability, low initial investment, low operation and maintenance costs, and long service life. Currently, monorail cranes are of two types: traction type and self-driving type. Replacing traditional auxiliary transportation with monorail crane has a wide range of applications, is easy to operate and use, and has high flexibility. It can not only save a lot of manpower, improve efficiency, increase the output of the working face, greatly reduce the downtime of equipment moving and improve equipment utilization, but also improve the labor safety conditions of mining workers and auxiliary operations.
[0003] The track of the monorail crane is fixed on the top of the coal mine tunnel and cannot be moved. However, the transported materials or mechanical equipment may not be in the ideal position for the monorail crane to lift due to various factors. At this time, manpower is needed to move the transported materials or mechanical equipment. When the monorail crane is unloading, if the transported materials or mechanical equipment are unloaded to the center of the tunnel, due to space problems in some tunnels, it may cause difficulties for workers to pass or occupy other roads. Therefore, the research and design of a monorail crane structure with side lifting and side unloading functions is of great significance in reasonably occupying tunnel space and improving work efficiency. Summary of the invention
[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a monorail side lifting structure for underground coal mine transportation, which solves the problem of side lifting and side unloading functions in the monorail lifting system, as well as the problem of difficulty in passage for workers or occupation of roads used by other people during unloading, thereby improving the flexibility of space utilization in underground coal mine tunnels and reducing the consumption of human resources.
[0005] The present invention adopts the following technical scheme: a monorail side hanging structure for underground coal mine transportation, comprising an upper boom, a lower boom, an auxiliary leg, an upper boom hydraulic cylinder, a lower boom hydraulic cylinder, an auxiliary leg hydraulic cylinder, a guide rod, an auxiliary supporting oil cylinder, bolts, and a supporting plate, wherein the upper boom is connected to the lower boom, and the lower boom is connected to the auxiliary leg; the upper boom is connected to the upper boom hydraulic cylinder, the lower boom is connected to the lower boom hydraulic cylinder, and the auxiliary leg is connected to the auxiliary leg hydraulic cylinder; the lower boom, the auxiliary leg, the lower boom hydraulic cylinder, and the auxiliary leg hydraulic cylinder are connected to the supporting plate; the auxiliary supporting oil cylinder is fixed on the supporting plate; a guide rod is provided between the piston rod and the cylinder barrel of the auxiliary supporting oil cylinder.
[0006] Furthermore, the upper boom and the upper boom hydraulic cylinder are connected by a pin shaft, the lower boom and the lower boom hydraulic cylinder are connected by a pin shaft, and the upper boom and the lower boom are connected by a pin shaft, so as to improve the load capacity and ensure the normal operation of the mechanism.

[0008] Furthermore, a guide rod is arranged between the piston rod and the cylinder barrel of the auxiliary support cylinder. Regardless of whether the piston rod is extended or retracted, the guide rod is always in the guide hole. In this way, its limiting effect can be utilized to avoid bending and other deformations of the piston rod when it is working or subjected to unpredictable external forces.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] (1) The use of auxiliary outriggers and auxiliary support cylinders plays an auxiliary supporting role and can also reduce vibration during movement, ensuring the smooth movement of the mechanism;
[0011] (2) In this structure, a guide rod is arranged between the piston rod and the cylinder barrel of the auxiliary support oil cylinder. Regardless of whether the piston rod is extended or retracted, the guide rod is always in the guide hole.
