Description

Technical Field

[0001] This invention belongs to the field of hydraulic belt winding technology, and more specifically, relates to a hydraulic belt winding device for belt conveyors. Background Technology

[0002] Belt conveyors are mainly used for coal transportation in fully mechanized mining faces. The conveyors are installed in the roadways of the working face. As mining progresses, the conveyor belt gradually shortens. When the belt storage bin is full, the belt needs to be removed, rolled up, and transported away. This process is called the belt winding process. A hydraulic belt winding device is the main equipment for winding excess belt from a belt conveyor. Typically, a hydraulic belt winding device consists of a motor-pump unit, a multi-way directional valve group, a belt-pulling motor, a belt-winding motor, a rotating motor, and hydraulic cylinders for belt-pulling clamping, fixing clamping, and lifting. The motor-pump unit provides power to the three motors through the multi-way directional valve group, and the motors drive the hydraulic cylinders to complete the belt winding process.

[0003] In existing hydraulic belt winding devices, as the winding degree increases, the diameter of the conveyor belt roll becomes larger and larger, resulting in a larger torque that the winding device needs to overcome. This requires more power to complete the winding, increasing the load on the winding device and hindering its long-term operation. In addition, after winding, the belt can only be fixed manually and cannot be fixed automatically, which may lead to the belt loosening due to untimely manual operation.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To address the technical problems of existing hydraulic belt winding devices, where the conveyor belt roll diameter increases with winding depth, leading to greater torque and requiring higher power, thus increasing the load on the winding device and hindering its long-term operation, and where the belt can only be manually secured after winding (lacking self-secured function, potentially causing loosening due to delayed manual operation), the basic concept of this invention is as follows:

[0006] A hydraulic belt winding device for a belt conveyor includes a base plate, a hydraulic belt winding machine is installed at one top end of the base plate, the hydraulic belt winding machine includes a take-up reel installed on one side, two take-up reels are arranged symmetrically, and a clamping mechanism is provided inside the take-up reel for clamping the conveyor belt.

[0007] A fixing mechanism is provided between the top of the base plate and the bottom of the winding reel. The fixing mechanism includes a baffle and is used to prevent the conveyor belt from opening after winding is completed.

[0008] An auxiliary drive mechanism is provided on one side of the top of the base plate. The auxiliary drive mechanism includes an auxiliary roller and is used to drive the conveyor belt.

[0009] A transmission mechanism is provided between the auxiliary drive mechanism and the hydraulic winding machine, and the transmission mechanism is used to transmit the power of the hydraulic winding machine to the auxiliary roller.

[0010] In a preferred embodiment of the present invention, rectangular slots are provided on opposite sides of the two winding reels. Uprights are installed at the upper and lower ends of the inner wall of the rectangular slots. The clamping mechanism includes clamping bars, and two clamping bars are provided. The two ends of the two clamping bars are respectively movably sleeved on the uprights on both sides. A first spring is movably sleeved on the uprights located on the outer part of the two clamping bars. The two ends of the first spring are respectively installed on one side of the clamping bar and one end of the inner wall of the rectangular slot. The first spring is always in a compressed state.

[0011] In a preferred embodiment of the present invention, two auxiliary rollers are provided, one vertically and one vertically, and a first gear and a second gear are respectively installed at both ends of the two auxiliary rollers. The first gear and the second gear mesh with each other. A first support rod is rotatably connected to the outer side of the first gear and the second gear, and the bottom of the first support rod is installed on the top of the base plate.

[0012] In a preferred embodiment of the present invention, the transmission mechanism includes a first sprocket and a second sprocket. Two symmetrically distributed first sprockets and second sprockets are provided. The first sprocket and the second sprocket on the same side are meshed and connected by the same chain. The two ends of the first gear are connected to one side of the second sprocket through a rotating shaft. One end of the first sprocket is connected to one side of the winding reel through a rotating shaft.

[0013] In a preferred embodiment of the present invention, two symmetrically distributed second support rods are installed on the top of the base plate between the auxiliary drive mechanism and the winding reel. Turntables are rotatably connected to the top of the two second support rods on their sides that are close to each other. Two clamping rods are installed between the two turntables and are spaced apart. A correction wheel is installed between the two ends of the two clamping rods.

[0014] In a preferred embodiment of the present invention, a top rod is installed at the bottom of the turntable. The top rod has an L-shaped cross-section and a second spring is installed at the bottom of the top rod. The other end of the second spring is installed at the top of the base plate, and the bottom of the second spring is closer to the hydraulic winding machine end relative to the top. The second spring is always in a stretched state.

[0015] In a preferred embodiment of the present invention, the baffle has an arc-shaped cross-section, and telescopic rods are installed at both ends of the bottom of the baffle. The bottom of the telescopic rods is installed on the top of the base plate, and a third spring is movably sleeved on the outside of the telescopic rods. The third spring is always in a compressed state. A fixing block is installed at the bottom of the baffle, and a groove is provided on one side of the fixing block. Two symmetrically distributed baffles are rotatably connected to the top of the base plate, and the height of the baffles is adapted to the height of the groove.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] In this invention, one end of the conveyor belt is passed through two auxiliary rollers and clamped between two clamping bars. The spring force of the first spring causes the two clamping bars to clamp the conveyor belt. At this time, the hydraulic winding machine is started, which drives the take-up reel to rotate, thereby rotating the clamping bars and winding the conveyor belt. Simultaneously, the rotation of the take-up reel drives the first sprocket to rotate. The first sprocket, through chain engagement, drives the second sprocket to rotate. The second sprocket, in turn, drives the first gear to rotate. The first gear, through engagement, drives the second gear to rotate, thus rotating the two auxiliary rollers and conveying the conveyor belt. As the conveyor belt is fed to the hydraulic winding machine, the more conveyor belt is wound on the clamping bar, the larger the resulting conveyor belt roll becomes. At this point, the angle between the winding position of the conveyor belt and the clamping bar increases, causing the clamping bar to rotate. The rotation of the clamping bar causes the top rod to rotate and further stretches the second spring. When the winding is completed, the conveyor belt disengages from the clamping bar. At this time, the second spring pulls the top rod to reset, and the top rod strikes one end of the stop rod under inertia, causing one end of the stop rod to rotate. The stop rod rotates and disengages from the groove, thereby unlocking the fixing block. At this time, the elastic force of the third spring causes the baffle to rise and press against the conveyor belt roll to prevent it from loosening.

[0018] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0027] Example 1:

[0028] like Figures 1 to 5 As shown, a hydraulic belt winding device for a belt conveyor includes a base plate 1, a hydraulic belt winding machine 2 is installed at one end of the top of the base plate 1, the hydraulic belt winding machine 2 includes a take-up reel 3 installed on one side, two take-up reels 3 are symmetrically distributed, and a clamping mechanism is provided inside the take-up reel 3 for clamping the conveyor belt.

[0029] A fixing mechanism is provided between the top of the base plate 1 and the bottom of the winding reel 3. The fixing mechanism includes a baffle 21 and is used to prevent the conveyor belt from opening after winding is completed.

[0030] An auxiliary drive mechanism is provided on one side of the top of the base plate 1. The auxiliary drive mechanism includes an auxiliary roller 12 and is used to drive the conveyor belt.

[0031] A transmission mechanism is provided between the auxiliary drive mechanism and the hydraulic winding machine 2. The transmission mechanism is used to transmit the power of the hydraulic winding machine 2 to the auxiliary roller 12.

[0032] like Figures 1 to 5As shown, in a specific embodiment, rectangular grooves 4 are provided on opposite sides of the two take-up reels 3. Vertical rods 5 are installed at the upper and lower ends of the inner wall of the rectangular grooves 4. The clamping mechanism includes clamping bars 7, of which two are provided. The two ends of the two clamping bars 7 are movably sleeved on the vertical rods 5 on both sides. A first spring 6 is movably sleeved on the outer part of the vertical rods 5 located on the two clamping bars 7. The two ends of the first spring 6 are respectively installed on one side of the clamping bar 7 and one end of the inner wall of the rectangular groove 4. The first spring 6 is always in a compressed state. In this configuration, during use, one end of the conveyor belt is passed through two auxiliary rollers 12 and through the clamping rods 17, so that it is clamped between the two clamping bars 7. The elastic force of the first spring 6 drives the two clamping bars 7 to clamp the conveyor belt. The hydraulic winding machine 2 is started, which drives the take-up reels 3 to rotate, thereby driving the clamping bars 7 to rotate and wind up the conveyor belt.

[0033] Example 2:

[0034] like Figures 1 to 5 As shown, in a specific embodiment, there are two auxiliary rollers 12 arranged vertically, and a first gear 13 and a second gear 14 are respectively installed at both ends of the two auxiliary rollers 12. The first gear 13 and the second gear 14 mesh with each other. A first support rod 11 is rotatably connected to the outer side of the first gear 13 and the second gear 14. The bottom of the first support rod 11 is installed on the top of the base plate 1. The transmission mechanism includes a first sprocket 8 and a second sprocket 10. There are two symmetrically distributed first sprockets 8 and second sprockets 10. The first sprocket 8 and the second sprocket 10 on the same side are meshed with the same chain 9. The two ends of the first gear 13 are connected to one side of the second sprocket 10 through a rotating shaft. One end of the first sprocket 8 is connected to one side of the winding reel 3 through a rotating shaft. In this setup, the take-up reel 3 rotates while driving the first sprocket 8 to rotate. The rotation of the first sprocket 8, through the meshing of the chain 9, drives the second sprocket 10 to rotate. The rotation of the second sprocket 10 drives the first gear 13 to rotate. The first gear 13, through meshing, drives the second gear 14 to rotate, thereby causing the two auxiliary rollers 12 to rotate and conveying the conveyor belt to the hydraulic winding machine 2.

[0035] like Figures 1 to 5 As shown, furthermore, two symmetrically distributed second support rods 15 are installed on the top of the base plate 1 between the auxiliary drive mechanism and the winding reel 3. A turntable 16 is rotatably connected to the top of each of the two second support rods 15, with the tops of the two second support rods 15 close to each other. Two clamping rods 17 are installed between the two turntables 16, maintaining a gap between them. A straightening wheel 18 is installed between the two ends of the two clamping rods 17. In this configuration, the direction of the conveyor belt can be corrected by the straightening wheel 18.

[0036] Example 3:

[0037] like Figures 1 to 5As shown, in a specific embodiment, a top rod 19 is installed at the bottom of the turntable 16. The top rod 19 has an L-shaped cross-section, and a second spring 20 is installed at the bottom of the top rod 19. The other end of the second spring 20 is installed at the top of the base plate 1, and the bottom of the second spring 20 is closer to the hydraulic winding machine 2 than the top. The second spring 20 is always in a stretched state. In this configuration, the more conveyor belt is wound on the clamping bar 7, the larger the conveyor belt roll becomes. At this time, the angle between the conveyor belt winding position and the clamping bar 17 increases, causing the clamping bar 17 to rotate. The rotation of the clamping bar 17 causes the top rod 19 to rotate and further stretch the second spring 20. When the winding is completed, the conveyor belt is disengaged from the clamping bar 17, and the second spring 20 pulls the top rod 19 to reset.

[0038] like Figures 1 to 5 As shown, the baffle 21 has an arc-shaped cross-section. Telescopic rods 22 are installed at both ends of the bottom of the baffle 21. The bottom of the telescopic rods 22 is installed on the top of the base plate 1. A third spring 23 is movably sleeved on the outer side of the telescopic rods 22. The third spring 23 is always in a compressed state. A fixing block 24 is installed at the bottom of the baffle 21, and a groove 25 is provided on one side of the fixing block 24. Two symmetrically distributed stop rods 26 are rotatably connected to the top of the base plate 1. The height of the stop rods 26 matches the height of the groove 25. In this configuration, the top rod 19 strikes one end of the stop rod 26 under inertia, causing one end of the stop rod 26 to rotate. The rotating stop rod 26 disengages from the groove 25, thereby unlocking the fixing block 24. At this time, the elastic force of the third spring 23 drives the baffle 21 to rise and press against the conveyor belt roll, preventing it from loosening.

[0039] The implementation principle of the hydraulic belt winding device for a belt conveyor in this embodiment is as follows: During use, one end of the conveyor belt passes through two auxiliary rollers 12 and through clamping rods 17, securing it between the two clamping rods 7. The elastic force of the first spring 6 drives the two clamping rods 7 to clamp the conveyor belt. At this time, the hydraulic winding machine 2 is started, driving the winding reel 3 to rotate, thereby driving the clamping rods 7 to rotate and winding the conveyor belt. Simultaneously, the rotation of the winding reel 3 drives the first sprocket 8 to rotate. The rotation of the first sprocket 8, through the meshing of the chain 9, drives the second sprocket 10 to rotate. The rotation of the second sprocket 10 drives the first gear 13 to rotate. The first gear 13, through meshing, drives the second gear 14 to rotate, thereby causing the two auxiliary rollers 12 to rotate. The conveyor belt is moved and transported to the hydraulic winding machine 2. The more conveyor belt is wound on the clamping bar 7, the larger the conveyor belt roll is formed. At this time, the angle between the winding position of the conveyor belt and the clamping bar 17 increases, and the clamping bar 17 is driven to rotate. The rotation of the clamping bar 17 drives the top rod 19 to rotate and further stretches the second spring 20. When the winding is completed, the conveyor belt is separated from the clamping bar 17. At this time, the second spring 20 pulls the top rod 19 to reset, and the top rod 19 strikes one end of the stop bar 26 under the action of inertia, thereby causing one end of the stop bar 26 to rotate. The stop bar 26 rotates and separates from the groove 25, thereby unlocking the fixing block 24. At this time, the elastic force of the third spring 23 drives the baffle 21 to rise and press against the conveyor belt roll to prevent it from loosening.
