Description

Technical Field

[0001] The utility model relates to the technical field of dust removal ducts, in particular to a monorail crane for self-moving dust removal ducts. Background Art

[0002] The dust removal fan is a kind of dust removal equipment specially used in the working environment of coal mines. It mainly uses the airflow generated by the fan to suck the air containing dust particles into the air duct. In the air duct, the air is filtered by the filter. Most of the dust particles will be trapped on the filter, while the clean air will continue to flow to the exhaust port and be discharged from the system. This working principle ensures the cleanliness and safety of the air in the working environment of coal mines.

[0003] When the dust removal air duct moves by itself, it needs to run along a monorail crane in conjunction with the pulley. Generally, the joints of the two guide rails are connected with screws, and special tools are needed to tighten or disassemble them. There are inconveniences in splicing and hanging, which causes the hanging time of the air duct to be too long, restricting the excavation progress and causing jamming when the pulley is moved, which seriously restricts the production efficiency. Therefore, the utility model proposes a monorail crane for self-moving the dust removal air duct to solve the problems existing in the prior art. Utility Model Content

The monorail crane for self-moving dust collection wind duct can achieve the purpose of quick installation, does not require special tools, and is convenient for efficient splicing and hanging of guide rails. The matching pulley drives the dust collection wind duct to move smoothly. As the excavation advances, the dust collection wind duct only needs to dismantle the rail body in the rear alley and move it to the head, which makes it convenient for the dust collection wind duct to continue to move with the excavation, thereby improving the excavation efficiency of the head-on excavation.

[0005] To achieve the purpose of the utility model, the utility model is implemented through the following technical solutions: a monorail hanger for self-moving dust removal duct, comprising a rail body and a buckle, the buckle is arranged at the front end of the top of the rail body, and the buckle comprises an axis plate and a bracket, the axis plate is connected to the rail body, the bracket is rotatably arranged on the inner side of the axis plate, a clamping rod is arranged at the upper end of the inner side of the bracket, a clamping seat is arranged at the rear end of the top of the rail body, and an inner cavity is arranged above one side of the clamping seat, a clamping block is elastically rotatably arranged in the inner cavity, and the clamping block is adapted to the clamping rod;

[0006] The front end of the bottom of the rail body is provided with a movable hoop head, and the rear end of the bottom of the rail body is provided with a movable plug matched with the movable hoop head.

[0007] A further improvement is that a connecting rod is connected to the lower part of the inner side of the bracket, and the connecting rod is integrally formed with the bracket.

[0008] A further improvement is that a limiting groove is provided at the middle end of the outer side of the clamping rod, and the length of the limiting groove is adapted to the length of the clamping block.

[0009] A further improvement is that the upper end of the clamping block is rotatably connected to the inside of the inner cavity via a hinge shaft, and a first spring is connected between the inner side of the clamping block and one side of the inner cavity.

[0010] A further improvement is that a guide groove is provided below the inner cavity, a guide block is provided below the clamping block, and the guide block is movably matched with the guide groove.
