Description

Technical Field

[0001] This utility model belongs to the field of scraper repair technology for scraper conveyors, specifically a scraper tooth repair device. Background Technology

[0002] Scraper conveyors are a type of transportation equipment widely used in industries such as coal and mining. Scraper conveyors are driven by motors to drive sprockets, which in turn drive scraper chains to circulate in the intermediate trough. When the scraper chains move in the trough, the scrapers push the materials placed in the intermediate trough forward together, thereby realizing the conveying of materials. Under the push of the scrapers, the materials are continuously conveyed from the head to the tail of the machine until they reach the designated unloading position.

[0003] Scraper misalignment in scraper conveyors refers to the displacement or misalignment of adjacent scrapers during operation, causing them to no longer maintain a normal straight alignment. During operation, scrapers are subjected to impacts and friction from materials such as coal and gangue, which can easily cause deformation and bending of the scraper edges. All of these factors can affect the normal alignment of the scrapers, leading to misalignment.

[0004] Scraper repair involves using a heat straightening method, which requires heating to reduce the scraper's hardness for straightening. The traditional method involves manually operating a flame gun to heat the scraper before using straightening tools. This process is inefficient and can easily result in operators being accidentally burned.

[0005] Therefore, a scraper-type malocclusion repair device is proposed to address the above problems. Utility Model Content

Limiting members 103 are fixedly connected to the bottom of the vertical rods 102. A clamping bolt 104 is provided on the limiting member 103. A gantry 105 is fixedly connected to the top of the square frame 101. The cylinder 2 is installed on the gantry 105. The support frame 1 is placed on the frame of the scraper conveyor, and the position of the repairer is fixed by the limiting member 103 and the clamping bolt 104 so that it corresponds to the position of the scraper that needs to be repaired.

[0033] Furthermore, guide rods 8 are fixedly connected to the four corners of the top of the movable frame 4. The guide rods 8 are connected to fixed ears 9, which are fixedly connected to the square frame 101 to ensure the stability of the movable frame 4 when it moves up and down.

[0034] Furthermore, the flame gun 6 is set at an angle on the movable frame 4, and the flame angle of the flame gun 6 corresponds to the position of the scraper, so that the flame of the flame gun 6 can be sprayed onto the scraper that needs to be repaired.

[0035] It is worth noting that the cooling assembly 7 includes a fan 701 mounted on the movable frame 4. The outlet of the fan 701 is connected to an air guide pipe 702, and the end of the air guide pipe 702 is connected to a pipe joint 703. The pipe joint 703 is connected to a nozzle 704.

[0039] Working principle and process: Place the support frame 1 on the frame of the scraper conveyor, and position the scraper to be repaired directly below the center of the repairer. Fix the position of the support frame 1 with the limiting member 103 and the tightening bolt 104. Start the cylinder 2, which extends and drives the U-shaped frame 3 and the movable frame 4 to move down until the straightening plate 505 holding the repair component 5 is positioned on the front and rear sides of the scraper to be repaired. At this time, the spray angle of the flame gun 6 is aimed at the scraper to be repaired, and the air outlet angle of the nozzle of the cooling component 7 is also aimed at the scraper to be repaired. The flame gun 6 sprays flames to heat the scraper to be repaired until it reaches a suitable temperature. Then, start the drive motor 502 of the clamping and repair assembly 5, and the lead screw 501 will rotate. Under the action of the thread and the limiting through groove 506, the threaded sleeve 503 will move closer to each other along the lead screw 501. Then, the L-shaped rod 504 will drive the straightening plate 505 to move closer to each other. The straightening plate 505 clamps the scraper, and the bending position of the scraper can be repaired. Start the drive motor 502 again to reverse the direction, so that the straightening plate 505 moves away from the scraper. Start the fan 701 of the cooling assembly 7. The outside air passes through the fan 701, the air guide pipe 702, and the pipe joint 703 and is sprayed out from the nozzle 704. The airflow can carry away the heat on the scraper, so that the scraper can be cooled quickly and put into use in time.
