Description

Technical Field

[0001] The invention relates to a wind tube moving hanging pulley assembly and application thereof, belonging to the technical field of wind tube installation. Background Art

[0002] The underground ventilation system of coal mines mainly consists of two parts: the main air supply system, which brings a large amount of air into the mine and distributes it to various mining sites; the auxiliary ventilation system, which distributes the air supplied by the main air supply system to various working faces and discharges the polluted gas from each work to the return air system. A good air supply system should be able to supply enough high-quality air underground to ensure the quality of the air at the working face, thereby ensuring the health of the workers, safety and normal production.

[0003] The patent document with patent number CN202222204538.7 is searched, and a suspension fixing device for a coal mine ventilation duct is disclosed, including: a top plate, two groups of suspension components distributed left and right are arranged at the bottom of the top plate, and the suspension components are used to fix the coal mine ventilation duct, and the two groups of suspension components include a first clamping plate and a second clamping plate for fixing the coal mine ventilation duct, the first clamping plate is arranged at the front side of the second clamping plate, and two storage cavities distributed up and down are provided inside the two first clamping plates. The present invention drives the two threaded blocks on the threaded rod to move by shaking the handle, and drives the first clamping plate and the second clamping plate to move to fix the coal mine ventilation duct, and then pulls the two mounting plates, and uses bolts to fix the mounting plate to the second clamping plate, and the mounting plate pulls the elastic band to loosen from the rotating shaft, and uses the first clamping plate, the second clamping plate and the two elastic bands to play a limiting role in the front and back, up and down of the coal mine ventilation duct, so as to improve the stability of the coal mine ventilation duct when in use.

[0004] However, the current technical considerations are not comprehensive and have the following disadvantages: 1. Mine shaft ventilation adopts local fan push-in ventilation, with wind ducts as the air supply path. The power of local fans is getting bigger and bigger, and the air supply distance is getting longer and longer. This requires the wind duct to be fixed, but the current wind duct fixing device is simply hung up with iron wire, which is easy to open at the connection of the wind duct, and the fixing effect of the wind duct is not good.

[0005] 2. With the promotion of efficient and rapid excavation, moving the wind duct has become a simple but tedious task. It is not compliant for the wind duct to exceed the prescribed distance from the head, so the wind duct will be moved frequently, which brings a lot of workload to the staff. In the past, the wind duct was hung on the side of the tunnel, which was easy to cause damage.

[0006] In order to solve one of the above problems, it is necessary to innovate and improve a wind tube moving hanging pulley assembly and its application. Summary of the invention

[0007] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is: how to achieve that when the air splitter is driven by external force to move along the monorail hanging beam, the first section of the air duct and the rear section of the air duct can also cooperate with the air splitter to move in the same direction. For this purpose, a wind duct moving hanging pulley assembly and application are provided to facilitate the movement of the wind duct, greatly reduce the labor intensity of on-site employees, and improve work efficiency.

[0013] Preferably, the air splitter hanger comprises two groups of air splitter hanger monomers arranged at intervals, the two groups of air splitter hanger monomers are respectively installed at the front and rear ends of the air splitter, and two groups of air splitter fixers are symmetrically installed on each group of air splitter hanger monomers.

[0014] Preferably, the air splitter hanger monomer includes a channel steel located below the monorail hanging beam, the channel steel opening is arranged upward, one end of the channel steel is detachably mounted with a left-side running wheel group and a left-side air splitter fixture, the other end of the channel steel is detachably mounted with a right-side running wheel group and a right-side air splitter fixture, the left-side running wheel group includes a first plug plate and a second plug plate which are vertically and spaced apart, one end of the channel steel is provided with a plurality of left-side slots which are plugged and matched with the first plug plate and the second plug plate, and the first plug plate and the second plug plate are connected with each other.

[0018] The air divider can be locked and unlocked by operating the left air divider holder and the right air divider holder simultaneously. The operation process of the left air divider holder is as follows: When the bottom nut C is tightened, the upper pressure plate overcomes the thrust of the compression spring B and moves downward relative to the channel steel, so that the fifth plug plate is deeply inserted into the corresponding left slot, thereby raising the height of the channel steel. The channel steel fits the monorail hanging beam, so that the lower bottom plate of the monorail hanging beam is clamped between the upper pressure plate and the channel steel, limiting the movement of the channel steel relative to the monorail hanging beam, thereby achieving the fixation of the position of the air distributor; When the bottom nut C is loosened, the channel steel moves downward relative to the monorail beam under its own weight, and the depth of the fifth plug plate inserted into the left slot becomes smaller, thereby lowering the height of the channel steel, so that a gap is generated between the monorail beam and the channel steel, until the left rail wheel B can contact the monorail beam and the upper pressure plate is separated from the monorail beam, thereby releasing the lock on the air splitter, and the air splitter can move along the monorail beam with the air splitter hanger.
