Description

Technical Field

[0001] The utility model relates to the technical field of coal mining equipment, in particular to a novel air guide curtain for a coal mining working face. Background Art

[0002] During the non-production period, the air guide curtain used in the original coal mining working face requires an employee to enter the front conveyor to hang the air guide curtain on the guard plate, and another employee is required to monitor outside the front conveyor, and report to the working face power station in advance to hang, lock, and power off the front conveyor, and make a power outage record; during production, it is necessary to manually enter the front conveyor to climb up and untie the fixed rope to retract it. The hanging of the air guide curtain is not only time-consuming, but also easy to damage and difficult to repair. It also requires the cooperation of two employees, and the employees also need to enter the front conveyor to climb up, which poses a safety hazard. It is one of the important factors restricting the safe and efficient production of the working face. The original air guide curtain used in the comprehensive mining working face has design problems and other safety hazards. It is necessary to design an easy-to-control air guide curtain to reduce labor intensity and improve work efficiency. Utility Model Content

The fixed pulley is installed on the top beam on the rear side of the rear column of the hydraulic support. A weight is installed at one end of the fixed pulley away from the top beam. The fixed pulley and the weight form an adaptive adjustment system that can adjust the air guide curtain. Four groups of fixed pulleys are provided.

[0005] As a further description of the above technical solution:

[0006] One end of the steel wire rope is fixed to the front end of the hydraulic support guard plate mechanism. A turnbuckle is installed on the steel wire rope. The turnbuckle fixes the air guide curtain flatly on the steel wire rope. The load-bearing rope is arranged at the front end of the hydraulic support guard plate mechanism.

[0007] As a further description of the above technical solution:

[0008] The three groups of fixed pulleys can form a fixed pulley telescopic system, and the fixing screw buckle connects the front end of the adaptive adjustment system air guide curtain and the fixed pulley telescopic system below the hydraulic support guard plate mechanism.

[0009] As a further description of the above technical solution:

[0010] The extended length and retracted length of the air guide curtain can be adjusted according to the actual needs of the coal mining working face to adapt to different working conditions and ventilation requirements.

[0011] The utility model has the following beneficial effects:

[0012] 1. In this utility model, through in-depth research on the hanging and recovery of the air guide curtain, drawing on common sense, adding a set of adaptive adjustment system, through the combination of the re-lumping system and the pulling system, ensuring that the air guide curtain can be adjusted forward and backward as the length of the telescopic beam of the bracket changes, improving the use of the air guide curtain, and the results continue to develop in a healthy manner, which not only reduces the time consumption, but also meets the needs of safe production in coal mines, and has made a great contribution to saving costs and reducing consumption for Dongtan Coal Mine.

[0013] 2. In the present invention, when using the air guide curtain, the way of using the air guide curtain is optimized and upgraded, reducing the number of two people working together to hang the air guide curtain to one person, and shortening the hanging time from 20 minutes to 2 minutes, solving the problem of personnel having to enter the front transport aircraft for high-altitude operations, improving work efficiency, and at the same time improving safety.
