Description

Technical Field

[0001] This utility model relates to a maintenance rack, specifically an adjustable maintenance rack for a transfer machine. Background Technology

[0002] Transfer conveyors are one of the indispensable mechanical equipment in the modern production of coal mining enterprises. They are used as transportation equipment between the scraper conveyor and the belt conveyor on the working face. After working for a long time, transfer conveyors need to be maintained using a maintenance frame.

[0003] However, existing maintenance racks are mostly fixed structures, making them difficult to adjust quickly for different sizes of transfer machines, resulting in poor applicability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable maintenance frame for transfer machines. Through a dual-displacement seat synchronous movement design, it can be adapted to different transfer machine wheel gauges. The cooperation between the limiting seat, limiting hole, and the pin and insert block seat locks the position of the device base and displacement seat, improving the stability of the device. This solves the problem that existing maintenance frames, mostly fixed structures, are not convenient for quick adjustment according to different transfer machine sizes, resulting in poor applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable maintenance frame for a transfer machine, including a device base, with displacement seats movably connected to both sides of the device base. A transmission assembly is provided at the center of the two displacement seats, which is used to movably connect the two displacement seats to the device base. A block seat is provided on one side of the displacement seat, and a locking assembly is provided above the block seat, which is used to fix the displacement seats to the device base. The transmission assembly includes a servo motor, with a transmission rod fixedly connected to the output end of the servo motor. A lead screw A is rotatably connected to the bottom end of the transmission rod, and both ends of the lead screw A extend to the outside of the two displacement seats and are rotatably connected to the device base. When the servo motor drives the transmission rod to rotate, the transmission rod transmits the power of the servo motor to the lead screw A, causing the lead screw A to drive the two displacement seats to move on both sides of the device base.

[0006] The locking assembly includes a limiting seat, which is an integral structure with the device base. A limiting hole is opened on the top surface of the limiting seat, and a pin is inserted into the inner side of the limiting hole. When the displacement seat moves to the appropriate position, the bottom end of the pin extends through the limiting hole to the inner side of the insert block seat.

[0007] Furthermore, a control panel is provided at the front end of the device base. The control panel is electrically connected to the transmission component, and the transmission component can be controlled through the control panel.

[0008] Furthermore, the bottom surface of the device base is provided with sliding grooves on both sides, and one end of the displacement seat extends to the inside of the sliding groove. When the displacement seat moves, it slides and moves inside the sliding groove. A positioning block is provided on the top surface of the displacement seat.

[0009] Furthermore, roller seats are fixedly connected to both sides of the displacement seat, and universal wheels are provided at the bottom of the roller seats. When the displacement seat moves, the roller seats assist the displacement seat in moving.

[0010] Furthermore, the displacement seat and the insertion block seat are integrated into one structure. A limiting groove is provided on the top surface of the insertion block seat. When the displacement seat moves to the appropriate position, the bottom end of the pin extends through the limiting hole to the inside of the limiting groove on the top surface of the insertion block seat.

[0011] Furthermore, bevel gears are provided at the bottom of the transmission rod and on the outer side of the center position of the lead screw A. When the transmission rod rotates, the transmission rod, in conjunction with the bevel gears, drives the lead screw A to rotate.

[0012] Furthermore, lead screw A is a double-threaded lead screw, with the threads at both ends of lead screw A being symmetrical to each other. When lead screw A rotates, lead screw A drives two displacement seats to move relative to each other on both sides of the device base.

[0013] The beneficial effects of this utility model are:

[0014] This adjustable maintenance frame for transfer machines features a dual-displacement seat synchronous movement design, making it suitable for different transfer machine wheel gauges. The cooperation between the limit seat, limit hole, and pin and block seat locks the position of the device base and displacement seat, improving the stability of the device. The design of the slide groove at the bottom of the device base reduces the accumulation of dust and external debris, thus minimizing the impact on the transmission components.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides an embodiment of an adjustable maintenance rack for a transfer machine, including a device base 1. Displacement seats 5 are movably connected to both sides of the device base 1. A transmission assembly is provided at the center of the two displacement seats 5. The transmission assembly is used to movably connect the two displacement seats 5 to the device base 1. The transmission assembly includes a servo motor 11. A transmission rod 13 is fixedly connected to the output end of the servo motor 11. A lead screw A12 is rotatably connected to the bottom end of the transmission rod 13. Both ends of the lead screw A12 extend to the outside of the two displacement seats 5 and are rotatably connected to the device base 1. A positioning block 6 is provided on the top surface of the displacement seats 5.

[0023] In this embodiment, when the servo motor 11 drives the transmission rod 13 to rotate, the transmission rod 13 transmits the power of the servo motor 11 to the lead screw A12, so that the lead screw A12 drives the two displacement seats 5 to move on both sides of the device base 1.

[0024] It should be noted that a control panel 4 is provided at the front end of the device base 1. The control panel 4 is electrically connected to the transmission component, and the transmission component can be controlled through the control panel 4. A bevel gear 14 is provided at the bottom end of the transmission rod 13 and on the outer side of the center position of the lead screw A12. When the transmission rod 13 rotates, the transmission rod 13 and the bevel gear 14 drive the lead screw A12 to rotate. The lead screw A12 is a double-threaded lead screw, and the threads at both ends of the lead screw A12 are symmetrical. When the lead screw A12 rotates, the lead screw A12 drives the two displacement seats 5 to move relative to each other on both sides of the device base 1.

[0025] Please see Figures 2-3 In this embodiment, a plug seat 8 is provided on one side of the displacement seat 5, and a locking component is provided above the plug seat 8. The locking component is used to fix the displacement seat 5 and the device base 1. The locking component includes a limit seat 2. The limit seat 2 and the device base 1 are an integral structure. A limit hole 3 is opened on the top surface of the limit seat 2, and a pin 9 is inserted into the inner side of the limit hole 3.

[0026] In this embodiment, when the displacement seat 5 is moved to the appropriate position, the bottom end of the pin 9 extends through the limiting hole 3 to the inner side of the insert seat 8.

[0027] It should be noted that the bottom surface of the device base 1 is provided with sliding grooves 10 on both sides. One end of the displacement seat 5 extends to the inner side of the sliding groove 10. When the displacement seat 5 moves, the displacement seat 5 slides and moves within the sliding groove 10. Roller seats 7 are fixedly connected to both sides of the displacement seat 5. Universal wheels are provided at the bottom of the roller seats 7. When the displacement seat 5 moves, the roller seats 7 assist the displacement seat 5 in moving. The displacement seat 5 and the plug seat 8 are an integral structure. A limit groove is provided on the top surface of the plug seat 8. When the displacement seat 5 moves to the appropriate position, the bottom end of the pin 9 extends through the limit hole 3 to the inner side of the limit groove on the top surface of the plug seat 8.

[0028] During operation, place the device base 1 in a suitable position and then fix it to the ground with bolts. Next, connect the power supply and start the device. Start the servo motor 11 via the control panel 4. When the servo motor 11 starts, it drives the transmission rod 13 to rotate. The transmission rod 13 transmits the power from the servo motor 11 to the lead screw A12, causing the lead screw A12 to move the two displacement seats 5 to the sides of the device base 1. This allows the two displacement seats 5 to be adjusted according to different types of transfer machines, improving the device's adaptability. When the displacement seat 5 moves to the appropriate position, the bottom end of the pin 9 on the top surface of the device base 1 extends through the limiting hole 3 to the inner side of the limiting groove on the top surface of the insert block seat 8, thereby fixing the position of the displacement seat 5 and preventing the displacement seat 5 from shifting after the transfer machine opens onto the top surface of the displacement seat 5, which would cause certain safety hazards to the device. Then, the transfer machine can be opened onto the top surface of the displacement seat 5 for maintenance. In addition, the bottom surface of the device base 1 is provided with a sliding groove 10, which reduces the covering of dust and external debris on the sliding groove 10, thus affecting the transmission of the transmission components.

[0029] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, and the power supply is also common knowledge in the art.
