[0002] In order to transport mineral raw materials quickly, mines usually use belt conveyors to transport different mineral materials to trucks or other conveying mechanisms. Belt conveyors are often guided by multiple rollers and restrict the circulation of the belt. They are quite stable during transport and can prevent materials from falling off during the process.

[0003] As mineral materials accumulate, the conveying distance of the conveyor also changes. However, most of these devices lack adjustment capabilities. If the length of the frame needs to be changed, the entire device needs to be operated, which increases the workload and requires the addition of other frames. It is difficult to accurately adapt to belt conveyors of different lengths, and disassembly and assembly are also quite inconvenient.

[0004] Now, a novel, detachable, lightweight frame for mining belt conveyors is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable lightweight frame for a mining belt conveyor, comprising a main body, with horizontal grooves provided on the front and rear surfaces of the main body, and a lead screw movably connected between the left and right sides of the grooves, a slider threaded to the outside of the lead screw, and a threaded groove provided between the left and right sides of the slider, a cavity provided on the left side of the horizontal groove, and worm gears movably connected at the front and rear ends of the lower part of the cavity, and a worm gear movably connected between the front and rear ends of the upper part of the cavity, a motor installed on the left side of the rear of the main body, a telescopic frame movably connected between the front and rear surfaces of the sliders, and a crossbar fixed between the front and rear ends of the right side of the telescopic frame.

[0007] As a further technical solution of this utility model, the output end of the motor is fixedly connected to the worm gear in front, the worm gear is meshed and connected above the worm wheel, and the lead screw is horizontally embedded in the threaded groove.

[0008] As a further technical solution of this utility model, the main body and the crossbar are respectively fixed with a frame on the outer front and rear sides, and the inner side of the frame is movably connected with a sleeve. A support rod is movably inserted into the inside of the sleeve. Bolt 2 is threadedly connected to the lower part of the sleeve, and bolt 1 is threadedly connected to the outside of the frame.

[0009] As a further technical solution of this utility model, a sleeve block is fixed on the front and rear surfaces of the left side of the telescopic frame, and a lever block is fixed on the left side of the front and rear sleeve blocks, and a bolt is threadedly connected in the lever block. A screw hole is provided on the front and rear ends of the slider.

[0010] As a further technical solution of this utility model, the bolt is embedded between the push block and the screw hole, and the push block rotates against the outer side of the screw hole.

[0011] As a further technical solution of this utility model, the front end and rear end of the main body and the top of the telescopic frame are respectively provided with slide rails in the horizontal direction, and five sets of assembly rods are movably connected in the slide rails. The interior of the assembly rod is provided with a strip groove in the vertical direction, and two sets of assembly pieces are movably connected in the strip groove. Four bolts are threaded to both sides of the assembly piece. Holes are provided in the vertical direction on both sides of the outer surface of the assembly rod.

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.

[0024] Please see Figure 1-4An embodiment of this utility model provides: a detachable lightweight frame for a mining belt conveyor, including a main body 1. Horizontal grooves 8 are horizontally arranged on the front and rear surfaces of the main body 1. A lead screw 9 is movably connected between the left and right sides inside the horizontal grooves 8. A slider 10 is threadedly connected to the outside of the lead screw 9. A threaded groove 22 is arranged between the left and right sides inside the slider 10. A cavity 7 is arranged on the left side of the horizontal groove 8. Worm gears 19 are movably connected to the front and rear ends of the lower part of the cavity 7. A worm gear 18 is movably connected between the front and rear ends of the upper part of the cavity 7. A motor 17 is installed on the left side of the rear of the main body 1. A telescopic frame 11 is movably connected between the surfaces of the front and rear sliders 10. A crossbar 13 is fixed between the front and rear ends of the right side of the telescopic frame 11.

[0025] The output end of the motor 17 is fixedly connected to the worm 18, the worm 18 is meshed with the worm wheel 19 above it, and the lead screw 9 is horizontally embedded in the threaded groove 22.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the motor 17 is started from the left rear of the main body 1 and the worm gear 18 is rotated. The worm gear 18 meshes with and pushes the worm wheels 19 installed at the front and rear ends of the bottom, guiding the symmetrical lead screws 9 to rotate in the transverse grooves 8 respectively. This allows the sliders 10 installed at the front and rear of the left side of the telescopic frame 11 to slide along the outer wall of the lead screw 9 through the threaded grooves 22. The telescopic frame 11 can be disassembled and reinstalled on the outside of the sliders 10 to adjust the distance between the main body 1 and the telescopic frame 11.

[0027] The main body 1 and the crossbar 13 are respectively fixed with the front and rear sides of the frame body 2, and the inner side of the frame body 2 is movably connected with the sleeve 4. The sleeve 4 is movably inserted with the support rod 5. The lower part of the sleeve 4 is threaded with the bolt 6. The outer side of the frame body 2 is threaded with the bolt 3.

[0028] The front and rear surfaces of the telescopic frame 11 are respectively fixed with sleeve blocks 16, and the left sides of the front and rear sleeve blocks 16 are respectively fixed with lever blocks 26, and the lever blocks 26 are threaded with bolts 21. The front and rear ends of the slider 10 are respectively provided with a circumferential screw hole 20, and the bolts 21 are embedded between the lever block 26 and the screw hole 20. The lever block 26 rotates against the outside of the screw hole 20.

[0029] Specifically, such as Figure 1 and Figure 3As shown, the telescopic frame 11 is rotated on the outside of the front and rear sliders 10. At this time, the lever 26 on the left side of the sleeve block 16 also fits against the surface of the screw hole 20. The assembly rod 15 is rotated, and the hole groove inside the lever 26 is aligned with a certain screw hole 20. Then, the bolt 3 21 is screwed in for reinforcement to prevent the telescopic frame 11 from returning to its original position after rotation. Then, the angle of the sleeve 4 is adjusted inside the four frames 2. After the first bolt 3 is rotated and tightened, the support rod 5 is pulled out from the bottom of the sleeve 4 and the second bolt 6 is screwed into the hole groove for reinforcement.

[0030] The front and rear ends of the main body 1 and the telescopic frame 11 are respectively provided with slide rails 14, and five sets of assembly rods 15 are movably connected in each slide rail 14. The interior of the assembly rod 15 is provided with a strip groove 27, and two sets of assembly pieces 25 are movably connected in the strip groove 27. Bolts 24 are threadedly connected to both sides of the assembly piece 25. Holes 23 are provided longitudinally on both sides of the outer surface of the assembly rod 15. Positioning holes 12 are distributed laterally on the outer side of the slide rail 14. Bolts 28 are threadedly connected to the bottom of the assembly rod 15.

[0031] Bolt 5 28 is longitudinally embedded between the assembly rod 15 and the positioning hole 12, and the shank of bolt 4 24 is embedded between the assembly piece 25 and the hole 23. The assembly rod 15 slides left and right along the inner wall of the slide rail 14, and the assembly piece 25 slides vertically along the inner wall of the strip groove 27.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the assembly components can be moved along the slide rails 14 at the front and rear ends of the top of the main body 1 or the telescopic frame 11, aligned with the positioning hole 12 and screwed in the bolts 28 for reinforcement. The height of the assembly piece 25 can be changed longitudinally along the strip groove 27, and then the bolts 24 on both sides can be rotated to lock it. The assembly components of the frame can be adjusted according to the different installation positions required by the belt conveyor.

[0033] Furthermore, the motor 17 is electrically connected to an external PLC control module to control the start and stop of the motor 17 and preset relevant parameters. The electrical connection relationship and control method between them are existing technologies, so they will not be described in detail.

[0034] Working Principle: In use, the motor 17 is first started at the rear left of the main body 1, and the worm gear 18 is rotated. The worm gear 18 engages with and pushes the worm wheels 19 installed at the front and rear ends of the bottom, guiding the symmetrical lead screws 9 to rotate in the transverse grooves 8. This allows the sliders 10 installed at the front and rear left sides of the telescopic frame 11 to slide along the outer wall of the lead screws 9 through the threaded grooves 22. The telescopic frame 11 can be disassembled and reinstalled on the outside of the sliders 10 to adjust the distance between the main body 1 and the telescopic frame 11. Then, the telescopic frame 11 is rotated on the outside of the front and rear sliders 10. At this time, the lever 26 on the left side of the sleeve block 16 also rotates against the surface of the screw hole 20, aligning with the groove inside the lever 26. After screwing in the screw hole 20, screw in the bolt 21 to reinforce it and prevent the telescopic frame 11 from resetting after rotation. Then, adjust the angle of the sleeve 4 inside the four frame bodies 2. After rotating the bolt 3 to tighten it, pull out the support rod 5 from the bottom of the sleeve 4 and screw in the hole groove with the bolt 6 to reinforce it. After adjusting the frame, maintain the stability of its structure. Finally, move the assembly rod 15 on the slide rails 14 at the front and rear ends of the main body 1 or the top of the telescopic frame 11, align it with the positioning hole 12 and screw in the bolt 28 to reinforce it. Change the height of the assembly piece 25 longitudinally along the strip groove 27, and then rotate the bolt 24 on both sides to lock it. The assembly components of the frame can be adjusted according to the different installation positions required by the belt conveyor.
