Description

Technical Field

[0001] This invention belongs to the technical field of transmission chain installation auxiliary tools, and specifically relates to a novel transmission chain installation auxiliary device. Background Technology

[0002] In the underground mining environment, the transmission chains of key equipment such as coal feeders need to be replaced or repaired regularly. Currently, there are severe challenges in the chain splicing (connection) process. Heavy chains sag significantly due to their own weight, making it difficult to control their posture in extremely narrow spaces such as roadways and equipment foundations. Operators cannot provide stable support or precise positioning. On-site, manual chain hoists are usually used for forced pulling, but this method has high safety risks and is difficult to operate. Because manual chain hoists and their traction rigging require a large installation and operating space, they are difficult to deploy effectively in the confined underground environment, resulting in low efficiency in the pulling process. Chain splicing depends entirely on the experience and physical strength of the operators. On average, each operation requires three people to work together for up to one hour, which seriously affects maintenance efficiency and production recovery.

[0003] In the existing chain connection process, general lifting tools such as hand chain hoists are not designed for precise chain connection. They can only provide unidirectional traction force and cannot restrain the chain from drooping in the vertical direction or swinging in the horizontal direction. This results in the chain being in an unstable state during the connection process and lacking a reliable support benchmark. In addition, the tool body and operating space requirements are large, making it difficult to adapt to specific narrow working conditions such as under the coal feeder. Furthermore, it relies entirely on manual observation and fine-tuning, lacking position guidance and preliminary leveling mechanisms, which makes the pin hole alignment process time-consuming and has a low success rate. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel auxiliary device for installing transmission chains.

[0005] To achieve the above objectives, the present invention provides a novel installation auxiliary device for a transmission chain, comprising a connecting plate, wherein first rotating rods are rotatably disposed on the lower parts of both sides of the connecting plate, and clamping blocks are rotatably disposed between the two first rotating rods on the right side and the two first rotating rods on the left side. Each side of the connecting plate is provided with a sliding groove, and there are two sets of sliding grooves. An adjustment mechanism is inserted into the two sliding grooves. The lower end of the adjustment mechanism is connected to two supporting mechanisms on both sides. The supporting mechanism includes a moving rod, the upper end of which is inclined. A connecting groove is opened in the middle of the lower end of the moving rod. A rotating screw is connected to the upper end of the inner wall of the connecting groove. A threaded cylinder is threaded to the lower part of the outer wall of the rotating screw. A lifting plate is connected to the lower end of the threaded cylinder. A fixed plate is connected to one side of the lifting plate. Three rollers are evenly connected to one side of the fixed plate.

[0006] In the above technical solution, further, the number of clamping blocks is two sets, and two clamping blocks are rotatably provided on both sides. Two of the second rotating rods are rotatably connected to the two sides of the connecting plate, respectively. An adjusting screw is threaded in the middle of the upper end of the connecting plate. The lower end of the adjusting screw extends through to the lower end of the connecting plate. A rotating handle is provided on the upper part of the outer wall of the adjusting screw. A moving block is rotatably provided at the lower end of the adjusting screw. Limiting rods are rotatably provided on both sides of the moving block. One of the limiting rods is rotatably connected to one side of the corresponding two first rotating rods, and the other limiting rod is rotatably connected to one side of the corresponding two first rotating rods.

[0007] In the above technical solution, a slot is further provided in the middle of one side of the two clamping blocks. The slot is arc-shaped and the inner wall of the two slots is provided with a buffer pad, which is made of silicone material.

[0008] In the above technical solution, the adjustment mechanism further includes adjustment rods, two adjustment rods are respectively inserted into two sliding grooves, the number of adjustment rods is two sets, one end of the two adjustment rods is provided with a pull plate, the middle of the outer wall of the two adjustment rods is provided with a first locking block, one side of the outer wall of the two adjustment rods is provided with a second locking block, and the other side of the outer wall of the two adjustment rods is provided with a third locking block.

[0009] In the above technical solution, the first, second, and third locking blocks are all made of silicone material, and the outer walls of the first, second, and third locking blocks are all arc-shaped. The cross-sectional shape of the sliding groove is arc-shaped, and the cross-sectional shape of the sliding groove is adapted to the cross-sectional shape of the first, second, and third locking blocks. One end of the two adjusting rods is connected to a moving plate.

[0010] In the above technical solution, a through hole is further provided on the upper part of one side of the movable rod, and a guide rod is connected inside the through hole. One end of the guide rod is connected to one side of the connecting plate, and the movable rod slides along the outer wall of the guide rod.

[0011] In the above technical solution, the upper end of the rotating screw extends through to the upper end of the moving rod, the upper end of the rotating screw is connected to a rotating block, the upper end of the threaded cylinder is located inside the connecting groove, and stabilizing blocks are connected to the upper parts of both sides of the threaded cylinder. Stabilizing grooves are opened on both sides of the inner wall of the connecting groove corresponding to the two stabilizing blocks, and the two stabilizing blocks slide inside the corresponding stabilizing grooves respectively.

[0012] In the above technical solution, a connecting rod is further connected to the middle of one side of the moving rod, and a sliding groove is opened in the middle of one side of the connecting rod. A slider is slidably connected inside the sliding groove. A sliding plate is connected to one side of the slider. The cross-sectional shape of the sliding plate is C-shaped. The sliding plate slides on the outer wall of the moving rod. A stabilizing rod is connected to one side of the sliding plate. The stabilizing rod is in the shape of an inverted L-shape. The lower end of the stabilizing rod is connected to one side of the upper end of the lifting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By adjusting the first, second, and third locking blocks on the lever and engaging with the arc-shaped sliding groove, three distinct positions are established: the clearance position, the working position, and the storage position. In the clearance position, the idler roller is completely away from the working area, providing interference-free space for the overall positioning and clamping operation of the device. In the working position, the idler roller is precisely locked directly below the chain, ensuring the stability of the support operation. In the storage position, the device returns to a compact state, facilitating handling and storage, reducing the difficulty of operation in narrow and dimly lit environments, and achieving a revolutionary transformation from chaotic placement to precise positioning.

[0014] The lifting mechanism drives the threaded cylinder to rise and fall by rotating the lead screw, which in turn moves the support assembly consisting of a fixed plate and multiple idlers vertically. This transfers the entire weight of the heavy chain from the operator's arm to the rigid structure of the device, completely eliminating fatigue, vibration, and safety risks caused by manual lifting. The idlers create a low-friction support plane for the chain, allowing the operator to make fine axial adjustments to the chain. This ensures that the mechanism maintains extremely high rigidity and positional accuracy even under heavy loads, improving the chain installation efficiency.

[0015] By adjusting the screw, moving block, limit rod, first rotating rod, clamping block and support mechanism to work together, the weight of the chain is borne by the idler roller. The force generated by rotating the adjusting screw is completely converted into the horizontal pulling force of the driving clamping block, thereby safely and smoothly pulling the two chain segments closer, replacing the dangerous and laborious manual chain hoisting method.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-9 The novel transmission chain installation auxiliary device shown includes a connecting plate 1. First rotating rods 2 are rotatably mounted on the lower parts of both sides of the connecting plate 1. Clamping blocks 3 are rotatably mounted between the two first rotating rods 2 on the right side and the two first rotating rods 2 on the left side. Two sets of sliding grooves 11 are provided on one side of the connecting plate 1. An adjustment mechanism is inserted into each of the two sliding grooves 11. Supporting mechanisms are connected to both sides of the lower end of the adjustment mechanisms. Each supporting mechanism includes a moving rod 17. The upper end of the moving rod 17 is inclined. A connecting groove 19 is provided in the middle of the lower end of the moving rod 17. A rotating screw 20 is connected to the upper end of the inner wall of the connecting groove 19. A threaded cylinder 21 is threadedly connected to the lower part of the outer wall of the rotating screw 20. A lifting plate 22 is connected to the lower end of the threaded cylinder 21. A fixed plate 23 is connected to one side of the lifting plate 22. Three rollers 24 are evenly connected to one side of the fixed plate 23. The first rotating rod 2 converts the force of the moving block 7 up and down into the clamping force of the clamping block 3. The clamping block 3 clamps the chain links. The sliding groove 11 can accurately guide the lateral movement of the adjustment mechanism. The adjustment mechanism can realize the rapid positioning and locking of the lifting mechanism in the three positions of avoidance, working and storage. The support mechanism can support the chain. The rotating screw 20 generates a spiral motion by manual rotation, which controls the vertical height of the idler roller 24. The threaded cylinder 21 can convert the rotational motion of the rotating screw 20 into its own linear lifting motion. The fixed plate 23 is the mounting bracket for the idler roller 24. As a support component that is in direct contact with the chain, the idler roller 24 is designed to rotate freely to stabilize the weight of the chain while greatly reducing the frictional resistance during fine-tuning of the chain axis, thus realizing the chain alignment operation.

[0020] like Figure 3 and Figure 6 As shown: There are two sets of clamping blocks 3. Each clamping block 3 has a second rotating rod 4 rotatably mounted on both sides. The two second rotating rods 4 are rotatably connected to the two sides of the connecting plate 1, respectively. An adjusting screw 5 is threaded in the middle of the upper end of the connecting plate 1. The lower end of the adjusting screw 5 extends through to the lower end of the connecting plate 1. A rotating handle 6 is mounted on the upper part of the outer wall of the adjusting screw 5. A moving block 7 is rotatably mounted on the lower end of the adjusting screw 5. Limiting rods 8 are rotatably mounted on both sides of the moving block 7. One limiting rod 8 is rotatably connected to one side of the corresponding two first rotating rods 2, and the other limiting rod 8 is rotatably connected to one side of the corresponding two first rotating rods 2. A slot 9 is opened in the middle of one side of each of the two clamping blocks 3. The slot 9 is arc-shaped. A buffer pad 10 is mounted on the inner wall of each of the two slots 9. The buffer pad 10 is made of silicone. Two sets of clamping blocks 3 act simultaneously on the chain to be connected from the left and right sides to ensure the balance of clamping force and the stability of centering. The second rotating rod 4 acts as the posture constraint rod of the clamping block 3, which can limit the clamping block 3 to always maintain a horizontal movement trajectory during the opening and closing process. The adjusting screw 5 can drive the moving block 7 to move up and down. The rotating handle 6 provides the operator with a labor-saving arm. The limiting rod 8 transmits the vertical lifting and lowering movement of the moving block 7 and converts it into a pulling force on the first rotating rods 2 on both sides. The slot 9 achieves a large-area wrapping contact with the chain link when clamping. The buffer pad 10 prevents surface scratches caused by contact with hard metal.

[0021] like Figures 2-5 As shown: The adjustment mechanism includes adjustment rods 12, two adjustment rods 12 are respectively inserted into two sliding grooves 11, and there are two sets of adjustment rods 12. One end of each adjustment rod 12 is provided with a pull plate. A first locking block 13 is provided in the middle of the outer wall of each adjustment rod 12. A second locking block 14 is provided on one side of the outer wall of each adjustment rod 12. A third locking block 15 is provided on the other side of the outer wall of each adjustment rod 12. The first locking block 13, the second locking block 14 and the third locking block 15 are all made of silicone. The outer walls of the first locking block 13, the second locking block 14 and the third locking block 15 are all arc-shaped. The cross-sectional shape of the sliding groove 11 is arc-shaped. The cross-sectional shape of the sliding groove 11 is adapted to the cross-sectional shape of the first locking block 13, the second locking block 14 and the third locking block 15. One end of each adjustment rod 12 is connected to a moving plate 16. The adjusting rod 12 slides inside the sliding groove 11. The pull plate provides a gripping surface for the operator to apply pulling or pushing force to move the adjusting mechanism. The first locking block 13 acts as a positioning device for the working position. When it is locked inside the sliding groove 11, it locks the supporting mechanism in the supporting position directly below the chain to prevent accidental displacement during operation. The second locking block 14 acts as a positioning device for the storage position. When it is locked inside the sliding groove 11, it locks the supporting mechanism in the retracted state close to the main body of the device, realizing the overall compactness of the tool and facilitating handling and storage. The third locking block 15 acts as a positioning device for the clearance position. When it is locked inside the sliding groove 11, it locks the supporting mechanism in the initial position completely away from the chain working area, providing interference-free space for the installation and clamping operation of the device. The movable plate 16 ensures the synchronous movement of the two adjusting rods 12, so that the left and right lifting mechanisms always move laterally on the same horizontal plane.

[0022] like Figures 7-9 As shown: A through hole is provided on the upper part of one side of the moving rod 17, and a guide rod 18 is connected inside the through hole. One end of the guide rod 18 is connected to one side of the connecting plate 1. The moving rod 17 slides along the outer wall of the guide rod 18. The upper end of the rotating screw 20 extends through to the upper end of the moving rod 17. A rotating block is connected to the upper end of the rotating screw 20. The upper end of the threaded cylinder 21 is located inside the connecting groove 19. Stabilizing blocks 25 are connected to the upper parts of both sides of the threaded cylinder 21. Stabilizing grooves are provided on both sides of the inner wall of the connecting groove 19 at the locations corresponding to the two stabilizing blocks 25. 25 slides inside the corresponding stabilizing groove. A connecting rod 26 is connected to the middle of one side of the moving rod 17. A sliding groove 27 is opened in the middle of one side of the connecting rod 26. A slider 28 is slidably connected inside the sliding groove 27. A sliding plate 29 is connected to one side of the slider 28. The cross-sectional shape of the sliding plate 29 is C-shaped. The sliding plate 29 slides on the outer wall of the moving rod 17. A stabilizing rod 30 is connected to one side of the sliding plate 29. The stabilizing rod 30 is in the shape of an inverted L. The lower end of the stabilizing rod 30 is connected to one side of the upper end of the lifting plate 22. The guide rod 18 provides guidance for the lateral movement of the moving rod 17, enabling the entire support mechanism to perform smooth linear reciprocating motion relative to the connecting plate 1. Rotating the lead screw 20 can drive the threaded cylinder 21 to move linearly up and down. The connecting groove 19 is used to accommodate and protect the upper part of the threaded cylinder 21, while providing movement space for the stabilizing block 25. As the lifting plate 22 moves up and down, the stabilizer bar 30 simultaneously drives the slide plate 29 and the slider 28 to slide inside the slide groove 27, forming a strong lateral support for the lifting plate 22 and preventing the roller 24 from swaying or deflecting under heavy load.

[0023] Working principle: When using the device, before operation, the adjusting rod 12 is located on the outermost side, and the third locking block 15 on it is locked into the sliding groove 11 on the side of the connecting plate 1, forming a clearance position for the idler roller 24. At this time, the entire lifting mechanism and the idler roller 24 are located outside the device, completely away from the working area below the chain, providing interference-free space for the movement and initial positioning of the device.

[0024] The operator moves the entire device between the two transmission chains to be connected, so that the connecting plate 1 spans across the chain. The operator rotates the handle 6 clockwise, which drives the adjusting screw 5 fixed to it to rotate. Since the adjusting screw 5 is threaded with the upper middle part of the connecting plate 1, its rotational motion is converted into the upward movement of the moving block 7. The moving block 7 pulls the limit rods 8 hinged on both sides, and the limit rods 8 pull the first rotating rod 2 to rotate. The first rotating rod 2 drives the position of the clamping block 3 to be adjusted. The second rotating rod 4 limits the clamping block 3, so that the clamping block 3 always maintains a horizontal posture during the movement, achieving parallel closure. The two sets of clamping blocks 3 move inward horizontally in sync until the arc-shaped groove 9 on its inner side is securely engaged with the outer edge of the chain links on both sides. The silicone buffer pad 10 on the inner wall of the groove 9 provides flexible fit and anti-slip protection. At this point, the device is firmly clamped to the chain by the clamping blocks 3.

[0025] The operator then pulls the adjusting rod 12 toward the chain. The adjusting rod 12 drives the moving plate 16 and the two sets of support mechanisms to slide down the chain along the guide rod 18. When the adjusting rod 12 moves to a specific position, the first locking block 13 engages with the sliding groove 11. This position is the working position, ensuring that the two side rollers 24 are directly below the end of the chain to be connected.

[0026] Rotate the rotating blocks at the upper end of the rotating screw 20 in the two supporting mechanisms respectively. The rotation of the rotating screw 20 drives the threaded cylinder 21, which is threadedly engaged with it, to move downward. Since the stabilizing blocks 25 on both sides of the threaded cylinder 21 slide inside the two stabilizing grooves respectively, the threaded cylinder 21 is prevented from rotating. Therefore, the threaded cylinder 21 drives the lifting plate 22, the fixed plate 23 and the roller 24 to move up and down as a whole.

[0027] The operator visually observes and adjusts the height of the two side rollers 24 to ensure they rise smoothly to the connection ends of the chains on both sides, preventing the chains from sagging due to their own weight. This also lifts and stabilizes the ends of the two chains on the same horizontal plane. When the lifting plate 22 moves up and down, it drives the stabilizing rod 30 to move the slide plate 29 and the slider 28 up and down. The slider 28 slides inside the slide groove 27, ensuring the stability of the lifting plate 22 during movement.

[0028] After the idler roller 24 provides stable vertical support for the chain, the chain is brought closer together. Continue to turn the handle 6 clockwise to move the moving block 7 upward. This is converted into a strong horizontal inward pulling force on the clamping block 3 through the limiting rod 8 and the first rotating rod 2. Since the clamping block 3 has clamped the chain and the weight of the chain has been borne by the idler roller 24, the two clamping blocks 3 pull the two chain segments. The two chain segments move along the idler roller 24 towards the center, bringing the ends of the two chain segments closer together to the preset distance. This distance is slightly equal to the thickness of a connecting chain block.

[0029] Once the chain is pulled closer, the operator can easily adjust the chain slightly by hand to align the pin holes at both ends of the chain links. Then, the operator places the connecting chain block into the gap between the two chain segments and smoothly inserts the pin to complete the chain connection.

[0030] After the chain is connected, remove the device, rotate the screw 20 in the opposite direction to lower the roller 24 so that it is completely separated from the chain, push the adjusting rod 12 outward so that the third locking block 15 is locked into the sliding groove 11, so that the roller 24 is away from the chain, and then rotate the handle 6 counterclockwise to move the moving block 7 down, drive the clamping block 3 to open in parallel through the linkage mechanism, release the clamping of the chain, remove the device from the connected chain, and complete all operations; Then, pulling the pull plate moves the two adjusting rods 12, and the second locking block 14 engages with the sliding groove 11, causing the lifting mechanism to retract and fit tightly against the main body of the device, presenting a compact state, which is convenient for handling and storage. The operating sequence of this device is as follows: First, the clamping mechanism establishes an initial connection with the chain to provide an installation reference for the entire device. Then, while the chain is still in a slack state, the two ends of the chain are lifted and adjusted to the same predetermined working plane by the independently lifting and lowering support mechanisms on both sides. In this state, the clamping mechanism is then driven to perform a pulling action, which solves the problem that heavy chains are difficult to center directly due to their own weight, sag, or misalign.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
