Description

Technical Field

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

[0002] The hydraulic belt winding device is a standard component for extendable belt conveyors used in underground coal mines. Its function is to quickly and efficiently wind the conveyor belt from a full storage bin onto the winding device's reel. The horizontal rotation of the winding device then moves the coiled conveyor belt outside the machine frame, where it is transported away using auxiliary transport vehicles. This equipment improves work efficiency and reduces the labor intensity of workers.

[0003] For example, Chinese patent CN214989399U, entitled "A Hydraulic Belt Winding Device for Anti-Pinching Belt Conveyors," discloses a hydraulic belt winding device for belt conveyors. One end of the mounting frame is equipped with a winding assembly. End plates are rotatably sleeved at both ends of the rotating shaft. An adjusting screw is threaded through one end of the top surface of each end plate. One end of the adjusting screw and one end of the guide rod are respectively connected to both ends of the push plate via rotatable connection and welding. Rubber rings are bonded to the edge of the extrusion plate. Contact plates and the extrusion plate are connected by extrusion springs. An anti-rolling edge assembly is provided near the rotating shaft on the mounting frame. Top frames are slidably mounted at both ends of the slide rail. A roller is mounted at one end of each top frame. A deceleration rod is slidably mounted inside the internally threaded tube. In this invention, during belt winding, the spacing between the contact plates is adjusted according to the width of the conveyor belt to guide the conveyor belt winding between the contact plates. The contact plates rotate with the rotating shaft, synchronously with the belt winding, preventing friction against the edges of the hydraulic winding device that could cause belt wear. The winding is neat and less prone to pinching.

[0004] While the hydraulic belt winding device for anti-pinch belt conveyors described in the aforementioned patent is practical and convenient, it also has shortcomings. During the winding process, the existing hydraulic belt winding device cannot adjust according to the belt size when the belt width is different, which greatly limits the winding device. The belt is prone to displacement during the winding process, which may lead to uneven tension and loosening of the belt. Summary of the Invention

[0005] The purpose of this invention is to provide a hydraulic belt winding device for belt conveyors to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic belt winding device for a belt conveyor, comprising a frame, a transmission assembly, and a linkage assembly. A rotating disk is rotatably connected to the frame. Multiple supporting circular plates are radially slidably connected to one side of the rotating disk in a circumferential array. Multiple stop bars are reciprocally slidably connected to one side of the rotating disk. Through the transmission assembly, each stop bar rotates from a horizontal state to a state parallel to one end of the rotating disk during the horizontal sliding motion away from the rotating disk. Each stop bar has a first stroke and a second stroke during its movement toward the rotating disk. The linkage assembly drives each supporting circular plate to slide radially through the first stroke of each stop bar. During the second stroke of the horizontal sliding motion of each stop bar toward the rotating disk, the distance between the stop bar and the rotating disk is adjusted to accommodate belts of different widths.

[0007] Furthermore, one side of the rotating disk is provided with multiple driving units in a circumferential array. Each driving unit includes a first rotating rod, a guide rod, and a movable seat. The guide rod is horizontally disposed on one side of the movable disk. The first rotating rod is rotatably connected to one side of the movable disk and rotatably connected inside the movable seat. Driven by the rotation of the first rotating rod, the movable seat is horizontally slidably sleeved on the guide rod. A rotating shaft is rotatably connected inside the movable seat, and each of the stop rods is sleeved with each rotating shaft in a corresponding manner.

[0008] Furthermore, two first spiral grooves are symmetrically formed on the first rotating rod, and the tail ends of the two first spiral grooves are connected. The movable seat is provided with a first protrusion, and the first protrusion slides and engages with the two first spiral grooves in sequence.

[0009] Furthermore, the transmission assembly includes a plurality of first gears and a plurality of racks, each rack meshing with each first gear in a one-to-one correspondence, each rack being fixedly connected to the inner wall of each supporting circular plate, and each first gear being coaxially fixedly connected to one end of each rotating shaft in a one-to-one correspondence.

[0010] Furthermore, each of the first rotating rods is fixedly fitted with an irregular gear, and an internal gear ring is rotatably connected to one side of the rotating disk, with each of the irregular gears meshing with the internal gear ring.

[0011] Furthermore, the linkage assembly includes a second gear, a second rotating rod, and a movable disk. The second rotating rod is rotatably connected to one side of the rotating disk. The second gear is fixedly sleeved on the second rotating rod. The second gear is disposed among multiple irregular gears, and each of the irregular gears meshes with the second gear. The second rotating rod is rotatably connected inside the movable disk. Driven by the rotation of the second rotating rod, the movable disk is horizontally slidably sleeved on multiple guide rods. A hinge rod is hinged between the peripheral side of the movable disk and the inner wall of each supporting plate.

[0012] Furthermore, a second spiral groove is provided on the second rotating rod, and a second protrusion is provided inside the movable disk, with the second protrusion slidably connected to the second spiral groove.

[0013] Furthermore, one side of the rotating disk is provided with multiple sliding grooves arranged in a circumferential array, and a slider is slidably connected in each of the sliding grooves. Each slider is fixedly connected to one end of each supporting plate near the rotating disk.

[0014] Furthermore, each of the irregular gears is provided with a first meshing tooth group and a second meshing tooth group. The first meshing tooth group and the second meshing tooth group are not connected. Each of the second meshing tooth groups is meshed with the internal gear ring, and each of the first meshing tooth groups is meshed with the second gear.

[0015] Compared with the prior art, the present invention provides the following advantages: The belt conveyor uses a hydraulic winding device to drive each stop bar to move horizontally away from the rotating disc. Through the transmission component, each stop bar is made to be in a vertical state, preventing the belt from slipping off from one end and falling off during winding. Each stop bar slides in the gap between each support plate, and during the first stroke of horizontal sliding towards the rotating disc, the linkage component drives each support plate to slide radially along the rotating disc. Each support plate forms a cylinder to facilitate belt winding. During the resetting process of each support plate, the internal support force on the belt can be reduced, making it easier to remove the belt. Then, each stop bar continues to slide horizontally towards the rotating disc, and the distance between each stop bar and the rotating disc can be adjusted to accommodate belts of different widths, preventing the belt from shifting and falling off during winding.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Please see Figure 1-14The present invention provides a technical solution: a hydraulic belt winding device for a belt conveyor, comprising a frame 1, a transmission assembly, and a linkage assembly. A rotating disk 2 is rotatably connected to the frame 1. Multiple supporting circular plates 3 are radially slidably connected in a circumferential array on one side of the rotating disk 2. Multiple stop rods 16 are reciprocally slidably connected to one side of the rotating disk 2. Through the transmission assembly, each stop rod 16 rotates from a horizontal state to a state parallel to one end of the rotating disk 2 during the horizontal sliding process away from the rotating disk 2. Each stop rod 16 has a first stroke and a second stroke during the movement towards the rotating disk 2. The linkage assembly drives each supporting circular plate 3 to slide radially during the first stroke of each stop rod 16. During the second stroke of the horizontal sliding process of each stop rod 16 towards the rotating disk 2, the distance between the stop rod 16 and the rotating disk 2 is adjusted to accommodate belts of different widths.

[0034] As a preferred technical solution, multiple drive units are arranged in a circular array on one side of the rotating disk 2. Each drive unit includes a first rotating rod 11, a guide rod 12, and a movable seat 17. The guide rod 12 is horizontally arranged on one side of the movable disk 7. The first rotating rod 11 is rotatably connected to one side of the movable disk 7 and is rotatably connected inside the movable seat 17. Driven by the rotation of the first rotating rod 11, the movable seat 17 is horizontally slidably sleeved on the guide rod 12. A rotating shaft 8 is rotatably connected inside the movable seat 17. Each stop rod 16 is sleeved one-to-one with each rotating shaft 8. Specifically, the first rotating rod 11... Two first spiral grooves 13 are symmetrically opened on the rod 11, and the tail ends of the two first spiral grooves 13 are connected. The moving seat 17 is provided with a first protrusion, which slides with the two first spiral grooves 13 in sequence. When the first rotating rod 11 is rotated, the guide rod 12 restricts the circumferential rotation of the moving seat 17. Through the sliding connection between the first protrusion and the two first spiral grooves 13, the moving seat 17 drives the stop rod 16 to move away from the rotating disk 2. After the winding is completed, each stop rod 16 is reset and horizontally placed in each support plate 3, which facilitates the subsequent removal of the coiled belt away from the rotating disk 2.

[0035] As a preferred technical solution, the transmission assembly includes multiple first gears 15 and multiple racks 14. Each rack 14 meshes with each first gear 15 in a one-to-one correspondence. Each rack 14 is fixedly connected to the inner wall of each supporting circular plate 3. Each first gear 15 is coaxially fixedly connected to one end of each rotating shaft 8 in a one-to-one correspondence. Specifically, during the process of each stop bar 16 moving horizontally away from the rotating disk 2, each rack 14 meshes with the corresponding first gear 15 for transmission. The first gear 15 drives the stop bar 16 to rotate to a vertical state through the rotating shaft 8, so as to prevent the belt from deviating and slipping off from one end and falling off when winding the belt.

[0036] In specific implementation, an irregular gear 19 is fixedly sleeved on each of the first rotating rods 11, and an internal gear ring 20 is rotatably connected to one side of the rotating disk 2. Each irregular gear 19 is meshed with the internal gear ring 20. Specifically, the internal gear ring 20 can realize the synchronous rotation of each irregular gear 19, so that each of the first rotating rods 11 can rotate synchronously to drive the moving seat 17 to reciprocate, thereby improving the synchronization. Preferably, a servo motor 21 can be set in the rotating disk 2, and the output end of the servo motor 21 is coaxially fixedly connected to one end of one of the first rotating rods 11.

[0037] As a preferred technical solution, the linkage assembly includes a second gear 18, a second rotating rod 9, and a movable disk 7. The second rotating rod 9 is rotatably connected to one side of the rotating disk 2. The second gear 18 is fixedly sleeved on the second rotating rod 9 and is positioned among multiple irregular gears 19, with each irregular gear 19 meshing with the second gear 18. The second rotating rod 9 is rotatably connected inside the movable disk 7. Driven by the rotation of the second rotating rod 9, the movable disk 7 slides horizontally onto multiple guide rods 12. A hinge rod 6 is hinged between the peripheral side of the movable disk 7 and the inner wall of each supporting circular plate 3. Specifically, the second rotating rod 9 has a second spiral groove 10, and the movable disk 7 has a second protrusion that slides slidably with the second spiral groove 10. During the first stroke of horizontal sliding towards the rotating disk 2, each irregular gear 19 drives the second gear 18 to rotate, and through the spiral transmission of the second rotating rod 9, drives the movable disk 7. The rotating disk 7 moves horizontally towards the rotating disk 2, and the guide rods 12 restrict the circumferential rotation of the moving disk 7. Since multiple grooves 4 are arranged in a circumferential array on one side of the rotating disk 2, a slider 5 is slidably connected in each groove 4. Each slider 5 is fixedly connected to the end of each support plate 3 near the rotating disk 2. The grooves 4 restrict each support plate 3 to only move radially. The moving disk 7 pushes each support plate 3 to move radially through the hinge rod 6. This not only reduces the internal support force on the belt during the reset process of each support plate 3, making it easier to remove the belt, but also drives the corresponding rack 14 to move synchronously at the same time. When the vertical stop rods 16 slide horizontally towards the rotating disk 2, the rack 14 has already disengaged from the meshing position. This ensures that the stop rods 16 remain vertical during the horizontal sliding process towards the rotating disk 2, which can adapt to the winding of belts of different widths and prevent the belt from shifting and falling off during the winding process.

[0038] As a preferred technical solution, each irregular gear 19 is provided with a first meshing tooth set 22 and a second meshing tooth set 23. The first meshing tooth set 22 and the second meshing tooth set 23 are not connected. Each second meshing tooth set 23 is meshed with the internal gear ring 20. Each first meshing tooth set 22 is meshed with the second gear 18. Specifically, the second meshing tooth set 23 is always meshed with the internal gear ring 20. The servo motor 21 drives one of the first rotating rods 11 to rotate, which in turn drives the irregular gear 19 on the first rotating rod 11 to rotate. The first meshing tooth set 22 and the second meshing tooth set 23 on the irregular gear 19 rotate synchronously. The second meshing tooth set 23 is driven by meshing transmission. When the internal gear ring 20 rotates, and each stop lever 16 moves away from the rotating disk 2, the first meshing gear set 22 does not mesh with the second gear 18. When each stop lever 16 moves in the first stroke in the direction of the rotating disk 2, the first meshing gear set 22 meshes with the second gear 18, so that each support plate 3 drives the corresponding rack 14 to move radially. Then, according to the width of the belt, in the second stroke of each stop lever 16 moving in the direction of the rotating disk 2, the first meshing gear set 22 does not mesh with the second gear 18. The distance that each stop lever 16 needs to move can be adjusted to adapt to belts of different widths and avoid belt position deviation during the winding process.

[0039] As a preferred technical solution, the frame 1 is detachably connected to two symmetrically arranged load-bearing arms 24. The rotating disk 2 is rotatably connected to one of the load-bearing arms 24, and multiple supporting circular plates 3 are provided with a connecting bracket 25 at one end near the other load-bearing arm 24. The connecting bracket 25 has multiple sliding holes arranged in a circumferential array, and each supporting circular plate 3 has a threaded hole at one end near the other load-bearing arm 24. Bolts can be used to pass through the sliding holes and screw into the threaded holes to fix the connecting bracket 25 to one end of the multiple supporting circular plates 3 near the other load-bearing arm 24, or each supporting circular plate 3 near the other load-bearing arm One end of 24 has a socket. A pin is inserted through the sliding hole to fix the connecting bracket 25. The connecting bracket 25 is provided with a rotating column. The connecting bracket 25 is rotatably connected to another load-bearing arm 24 through the rotating column. Before each support plate 3 is reset, the other load-bearing arm 24 can be removed. By reverse-tightening the bolt or pulling out the pin, the connecting bracket 25 can be removed from the end of each support plate 3 near the other load-bearing arm 24 to continue the reset process. Neither the other load-bearing arm 24 nor the connecting bracket 25 will cause motion interference to the horizontal sliding and rotation of each stop bar 16.

[0040] Working principle: The belt conveyor uses a hydraulic winding device to start a servo motor 21, driving one of the first rotating rods 11 to rotate. Through the meshing of the second meshing gear set 23 with the internal gear ring 20, it drives each irregular gear 19 to rotate synchronously. Through the helical transmission of each first rotating rod 11, it drives each moving seat 17 to move the stop bar 16 horizontally away from the rotating disk 2. During this process, the first meshing gear set 22 does not mesh with the second gear 18, and the supporting plate 3 remains stationary. During this process, each rack 14 and its corresponding first gear 19 rotate simultaneously. A gear 15 engages in a transmission mechanism. The first gear 15 drives the stop rod 16 to rotate to a vertical position via the rotating shaft 8, preventing the belt from slipping off one end and falling off when the belt is wound. Each stop rod 16 slides horizontally in the gap between each support plate 3. During the first stroke of horizontal sliding towards the rotating disk 2, the first meshing gear set 22 engages with the second gear 18. Through the helical transmission of the second rotating rod 9, the moving disk 7 is driven to move horizontally towards the rotating disk 2. Through the hinge rod 6, each support plate 3 is pushed along the corresponding groove. 4. Sliding along the length direction, each supporting circular plate 3 forms a cylinder to facilitate belt winding, and the rack 14 has disengaged from the meshing position. Then, according to the belt width, during the second stroke when each stop bar 16 moves towards the rotating disk 2, the first meshing gear group 22 does not mesh with the second gear 18, allowing adjustment of the distance each stop bar 16 needs to move to adapt to belts of different widths and prevent belt position shift during winding. Then, the connecting bracket 25 is installed on each supporting circular plate 3 near the other using bolts or pins. One end of a load-bearing arm 24 is attached to the frame 1, and another load-bearing arm 24 is installed on the frame 1 to provide support for the device. Before resetting, the other load-bearing arm 24 can be removed. By reverse-tightening the bolts or pulling out the pins, the connecting bracket 25 can be removed from the end of each support plate 3 near the other load-bearing arm 24. Then, during the resetting process, the support plate 3 moves toward the center of the rotating disc 2, which can reduce the internal support force on the belt and make it easier to remove the belt. Then, each stop bar 16 is retracted into each support plate 3 to avoid blocking the belt from being removed.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
