Description

Technical Field

[0001] This utility model relates to a mid-groove grain size heating device, specifically a mid-groove grain size heating device that can achieve uniform temperature distribution. Background Technology

[0002] The central trough is a core component of scraper conveyors and transfer conveyors in underground coal mines, serving as a coal transport channel. Its structure is constructed by welding trough side steel to a central plate. The trough side is available in two types: cold-pressed and rolled. The central trough needs to possess high strength, high wear resistance, and good toughness to withstand harsh working conditions. To improve the structural performance of the central trough, heat treatment is required to ensure that its grain size meets the wear resistance requirements. Grain size is an important measure of the size of grains within a metallic material; a higher grade indicates finer grains. Heat treatment requires the use of heating devices.

[0003] In existing grain size heating devices for the central groove, the central groove is generally placed flat on the rotating base. Uneven heating at the top and bottom of the central groove leads to a decrease in the structural performance of the central groove. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a central groove grain size heating device that can uniformly distribute temperature, thus achieving uniform temperature distribution.

[0005] The technical solution of this utility model is as follows: A grain size heating device for a central groove with uniform temperature distribution includes a heating frame. A working motor is fixedly connected to the top of the heating frame. A conveyor belt is installed at the output end of the working motor. A connecting block is fixedly connected to the outer wall of the conveyor belt. A gear is screwed to the bottom end of the connecting block. A rack fixedly connected to the inner wall of the heating frame is engaged with the meshing surface of the gear. A clamping frame is welded to the bottom end of the gear. A pneumatic cylinder is fixedly connected to the inner wall of the clamping frame. A lifting block is fixedly connected to the output end of the pneumatic cylinder. Connecting rods are hinged to both ends of the lifting block. A clamping seat is hinged to the bottom end of the connecting rod. A clamping plate is welded to the bottom end of the clamping seat. A positioning block is welded to the outer wall of the clamping plate. A central groove body that fits into the outer wall of the positioning block is attached to the outer wall of the clamping plate. A heating base fixedly connected to the inner wall of the heating frame is provided on one side of the central groove body. An electric heating tube is provided on the outer wall of the heating base. A worktable is provided on one side of the heating frame. A temperature controller is provided on the outer wall of the worktable.

[0006] Based on the above structure, when the working motor is working, it drives the connecting block on the outer wall of the conveyor belt to move. The movement of the connecting block drives the central trough body at its bottom end to move into the heating frame. At the same time, when the connecting block moves, it drives the gear and rack to mesh, thereby driving the central trough body to slide and rotate. Then, the electric heating tube on the outer wall of the heating base is energized and heated by the temperature controller. The electric heating tube generates high temperature to uniformly heat the central trough body.

[0007] Preferably, the conveyor belt is ring-shaped, and the conveyor belt and the rack are concentrically distributed. In this embodiment, this facilitates continuous heating of the central trough body.

[0008] Preferably, the connecting blocks are equidistantly distributed along the outer wall of the conveyor belt. In this embodiment, this facilitates heating of multiple sets of central trough bodies.

[0009] Preferably, the clamping frame forms a rotating structure with the connecting block through gears and racks. In this embodiment, when the connecting block moves, it drives the gears and racks to mesh, thereby causing the central groove body to slide and rotate at the same time.

[0010] Preferably, the lifting block forms a sliding structure with the clamping frame through a connecting rod and a clamping seat. In this embodiment, when the lifting block slides, the connecting rod drives the clamping seat to slide horizontally along the inner wall of the clamping frame.

[0011] Preferably, the clamping plate is L-shaped, and the positioning blocks are equidistantly distributed along the outer wall of the clamping plate. In this embodiment, by setting the L-shaped clamping plate, it is beneficial to pre-position the central groove body and avoid the central groove body from falling off. The clamping seat slides and drives the positioning blocks on the outer wall of the clamping plate to fit against the inner wall of the central groove body, thereby stably clamping the central groove body through the clamping plate.

[0012] Preferably, the heating base is provided in four sets, and the four sets of heating bases are equidistantly distributed along the inner wall of the heating frame. The electric heating tubes are distributed in an "S" shape along the outer wall of the heating base. In this embodiment, by providing four sets of heating bases, it is convenient to control the electric heating tubes at different temperatures. By providing the electric heating tubes in an "S" shape, it is beneficial to heat the central tank body evenly.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with a clamping plate and a positioning block. In use, the main body of the middle groove is placed on the clamping plate. Then, the pneumatic push cylinder works to drive the lifting block to slide vertically along the inner wall of the clamping frame. This drives the clamping seat to slide horizontally along the inner wall of the clamping frame through the connecting rod. This causes the positioning block on the outer wall of the clamping plate to fit against the inner wall of the main body of the middle groove, thus achieving stable clamping of the main body of the middle groove.

[0014] 2. This utility model is equipped with gears and racks. When the working motor is working, it drives the connecting block on the outer wall of the conveyor belt to move, thereby moving the central trough body at its bottom end to the interior of the heating frame. When the connecting block moves, it simultaneously drives the gears and racks to mesh, thereby causing the central trough body to slide and rotate at the same time. Then, the electric heating tube on the outer wall of the heating base is energized and heated by the temperature controller. The electric heating tube generates high temperature to uniformly heat the central trough body. Attached Figure Description

Both ends of the lifting block 9 are hinged with connecting rods 10, and the bottom end of the connecting rod 10 is hinged with a clamping seat 11. The bottom end of the clamping seat 11 is welded with a clamping plate 12. The outer wall of the clamping plate 12 is welded with a positioning block 13. The outer wall of the positioning block 13 is fitted with a central groove body 14 that fits into the outer wall of the clamping plate 12. A heating base 15 is provided on one side of the central groove body 14 and is fixedly connected to the inner wall of the heating frame 1. An electric heating tube 16 is provided on the outer wall of the heating base 15. A workbench 17 is provided on one side of the heating frame 1. A temperature controller 18 is provided on the outer wall of the workbench 17.

[0020] Based on the above structure, when the working motor 2 is working, it drives the connecting block 4 on the outer wall of the conveyor belt 3 to move, thereby driving the central trough body 14 at its bottom end to move into the interior of the heating frame 1. When the connecting block 4 moves, it simultaneously drives the gear 5 to mesh with the rack 6, thereby driving the central trough body 14 to slide and rotate at the same time. Then, the electric heating tube 16 on the outer wall of the heating base 15 is energized and heated by the temperature controller 18. The electric heating tube 16 generates high temperature to uniformly heat the central trough body 14.

[0021] In one embodiment, the conveyor belt 3 is ring-shaped, and the conveyor belt 3 and the rack 6 are concentrically distributed to facilitate continuous heating of the central trough body 14.

[0022] In one embodiment, the connecting blocks 4 are equidistantly distributed along the outer wall of the conveyor belt 3, which facilitates heating of multiple sets of central trough bodies 14.

[0023] In one embodiment, the clamping frame 7 forms a rotating structure with the connecting block 4 via gear 5 and rack 6. When the connecting block 4 moves, it drives gear 5 and rack 6 to mesh, thereby causing the central groove body 14 to slide and rotate simultaneously.

[0024] In one embodiment, the lifting block 9 forms a sliding structure with the clamping frame 7 through the connecting rod 10 and the clamping seat 11. The lifting block 9 can drive the clamping seat 11 to slide horizontally along the inner wall of the clamping frame 7 through the connecting rod 10.

[0025] In one embodiment, the clamping plate 12 is L-shaped, and the positioning blocks 13 are equidistantly distributed along the outer wall of the clamping plate 12.

[0026] By setting an "L"-shaped clamping plate 12, it is beneficial to pre-position the central groove body 14 and prevent the central groove body 14 from falling off; the clamping seat 11 slides and drives the positioning block 13 on the outer wall of the clamping plate 12 to fit against the inner wall of the central groove body 14, thereby stably clamping the central groove body 14 through the clamping plate 12.

[0027] In one embodiment, four sets of heating bases 15 are provided, and the four sets of heating bases 15 are equidistantly distributed along the inner wall of the heating frame 1, while the electric heating tubes 16 are distributed in an "S" shape along the outer wall of the heating bases 15.

[0028] By setting four sets of heating bases 15, it is convenient to control the electric heating tubes 16 at different temperatures; by setting the electric heating tubes 16 in an "S" shape, it is beneficial to heat the central tank body 14 evenly.

[0029] When using this utility model, firstly, the central groove body 14 is placed on the clamping plate 12. Then, the pneumatic push cylinder 8 works, driving the lifting block 9 to slide vertically along the inner wall of the clamping frame 7. This causes the clamping seat 11 to slide horizontally along the inner wall of the clamping frame 7 via the connecting rod 10. This, in turn, causes the positioning block 13 on the outer wall of the clamping plate 12 to fit against the inner wall of the central groove body 14, thus achieving stable clamping of the central groove body 14 through the clamping plate 12.

[0030] Next, the working motor 2 starts working, driving the connecting block 4 on the outer wall of the conveyor belt 3 to move, thereby moving the central trough body 14 at its bottom end to the interior of the heating frame 1. When the connecting block 4 moves, it simultaneously drives the gear 5 to mesh with the rack 6, thereby causing the central trough body 14 to slide and rotate at the same time. Then, the electric heating tube 16 on the outer wall of the heating base 15 is energized and heated by the temperature controller 18. The electric heating tube 16 generates high temperature to uniformly heat the central trough body 14.
