Abstract
Description
Technical Field
[0001] This invention relates to the field of power construction, specifically to a high-efficiency traction device for long-distance cables. Background Technology
[0002] Tracked cable conveyors are core equipment for long-distance cable traction construction. They mainly use metal chains spliced together to form a ring track, which is combined with sprockets to form a drive wheel assembly. The sprockets drive the metal chains to rotate in a cycle. Multiple rubber blocks are installed on the surface of the chain. During operation, the rubber blocks of two sets of tracks clamp the cable together. The cable is pushed by the friction between the rubber blocks and the cable sheath. Multiple devices can work together to complete long-distance continuous cable laying operations. It can effectively reduce the intensity of manual dragging and reduce cable sheath scratches. It is widely used in cable trenches, integrated pipe corridors and other engineering sites.
[0003] In existing cable conveyors, rubber blocks are fixed to the outside of the metal chain, and are locked in place by multiple fastening bolts that pass through the rubber blocks and chain plates installed on the chain. When the rubber blocks need to be replaced due to long-term friction and wear, the operator needs to first remove the outer protective plate of the track, loosen the track tensioning mechanism to relax the annular metal chain, and then unscrew all the fixing bolts in sequence to remove the worn rubber block. After assembling the new rubber block, all bolts are retightened, the track tension is adjusted, and the outer protective plate is restored. This bolt locking structure has a strong connection and high load-bearing capacity, and can withstand the continuous compressive load during cable traction. It is the assembly scheme commonly used in current tracked cable conveyors.
[0004] However, in long-haul multi-machine coordinated construction scenarios, a single complete replacement of the rubber block usually takes at least one to two hours. In long-distance laying projects such as tunnels and cable trenches, multiple conveyors are often put into operation simultaneously. If multiple machines experience rubber block wear problems one after another, the cumulative downtime will increase significantly. Long-term downtime will directly interrupt the continuous cable conveying rhythm and delay the overall construction progress. At the same time, the on-site disassembly and assembly procedures are cumbersome, require high construction experience from operators, and have high manual maintenance costs, making it difficult to meet the needs of efficient and continuous construction in power engineering. Therefore, it is necessary to optimize and improve the installation and fixing structure of the track rubber block. Summary of the Invention

[0025] Compared with the prior art, the beneficial effects of the present invention are:
[0026] 1. This invention, by incorporating components such as reinforcing rods, locking blocks, and locking slots, allows for easy maintenance. By pulling the unlocking rod, the transmission plate and unlocking frame can be moved, simultaneously releasing the positioning block's restriction on the positioning plate. Lifting the cover upwards will cause the transmission plate to simultaneously lift multiple rubber blocks for disassembly. During assembly, the locking slots and locking blocks of the rubber blocks can quickly engage, eliminating the need to remove and install bolts when replacing rubber blocks. This alleviates the problems of time-consuming rubber block replacement and prolonged equipment downtime during simultaneous construction of multiple devices, which slows down cable laying progress.
[0027] 2. This invention, by providing a support, a ball bearing, and a boss, allows the ball bearing at the bottom of the support to roll against the boss during track operation, thereby sharing the compressive load from the track, rubber block, and cable. This reduces wear caused by long-term pressure on the track, extends track service life, and reduces track replacement frequency. Simultaneously, by providing a horizontal roller, an extended frame, and vertical rollers, the horizontal rollers support the cable during traction operations, while the vertical rollers on both sides adhere to the outer wall of the cable, reducing lateral deviation during cable transport and minimizing wear caused by friction between the cable sheath and the edge of the rubber block.
[0028] 3. This invention, by setting up a sliding box, a transmission ear and a second spring, allows the second spring to push the transmission plate and the unlocking frame back to their initial positions after the pulling mechanism is reset, so that the positioning block re-fits the positioning plate under the action of the first spring, thus completing the locking of the cover. Each component is automatically reset by relying on the spring, reducing the number of manual reset operation steps. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0043] Please see Figures 1-12 The present invention provides the following technical solution: a long-distance cable high-efficiency traction device, comprising a frame 1, a track frame 2, a drive wheel 3, a track 4, and rubber blocks 7. The track 4 is equipped with interlocking reinforcing rods 5 and connecting blocks 6. The top of the reinforcing rods 5 is slidably connected to mating ears 8 mounted on the rubber blocks 7. Multiple mating ears 8 mounted on the rubber blocks 7 are interconnected by steel ropes 9. The bottom of the rubber blocks 7 has a slot 60 that slides with the connecting blocks 6. The track frame 2 is provided with a cover 10 covering the outside of the rubber blocks 7, and a positioning plate 11 is installed at the bottom of the cover 10. A limiting frame 14 adapted to the positioning plate 11 is installed on the top surface of the track frame 2, and interlocking positioning blocks 15 and springs are installed on the top of the limiting frame 14. Spring 16, and positioning block 15 is attached to the top surface of positioning plate 11; transmission plate 17, which is offset from rubber block 7, is slidably installed on the top of positioning plate 11, and multiple transmission ears 20 are installed on the top of transmission plate 17. Sliding box 21, which is slidably connected to transmission ears 20, is installed on the top of positioning plate 11, and spring 22 connected to transmission ears 20 is installed in sliding box 21; unlocking bracket 23, which is adapted to positioning block 15, is installed at the end of transmission plate 17, and the outer corner of positioning block 15 is designed with an angle. The cover 10 is provided with a pulling mechanism for pulling transmission plate 17. After the positioning plate 11 is released by unlocking bracket 23 in cooperation with positioning block 15, multiple sets of rubber blocks 7 can be lifted simultaneously, reducing the process of removing rubber blocks 7 individually.
[0044] In a preferred embodiment of the present invention, the reinforcing rod 5 is fixedly installed on the track 4, and the top of the reinforcing rod 5 protrudes from the top of the track 4, and the top corners of the reinforcing rod 5 are all designed with bevels; the length of the top of the reinforcing rod 5 protruding from the track 4 is greater than the length of the locking block 6, so that when installing the rubber block 7, the mating ear 8 is assembled first, and then the rubber block 7 can be directly pressed down to complete the assembly of the rubber block 7.
[0045] The outer wall of track 4 is attached to the outer wall of rubber block 7, and the mating ear 8 is installed on the outer wall of the top of rubber block 7 near the track 4. The cross-section of the locking block 6 is T-shaped, and the top of the locking block 6 is arc-shaped. The corners of the locking block 6 and the opening of the locking groove 60 are all chamfered. The chamfered structure can reduce the sliding resistance when the locking block 6 and the locking groove 60 are aligned and assembled.
[0046] As a preferred embodiment of the present invention, a support 61 fixedly connected to the bottom of the reinforcing rod 5 and the clamping block 6 is installed at the bottom of the track 4, and a first ball 62 is installed at the bottom of the support 61; a boss 63 in contact with the plurality of first balls 62 is installed at the top of the track frame 2, and the top surface of the boss 63 is located below the rubber block 7. During the operation of the equipment, the first balls 62 slide along the surface of the boss 63, which can share the load borne by the track 4 during operation.
[0047] As a preferred embodiment of the present invention, a pressure frame 12 is installed on the inner wall of the top of the cover 10, and multiple groups of second balls 13 attached to the top surfaces of the plurality of rubber blocks 7 are uniformly installed at the bottom of the pressure frame 12. The contact between the second balls 13 and the top surfaces of the rubber blocks 7 can reduce the frictional resistance generated when the rubber blocks 7 circularly move along with the track 4, and meanwhile the second balls 13 can also limit the top of the rubber blocks 7 to prevent the rubber blocks 7 from moving upward.
[0048] As a preferred embodiment of the present invention, the limiting frames 14 are symmetrically arranged on the top of the track frame 2, the limiting frames 14 are in a "匚"-shaped design, and the inner wall of the limiting frame 14 is attached to the outer wall of the positioning plate 11; the top corners of the limiting frames 14 are all designed with bevels, and the bevel tops of the limiting frames 14 can guide the positioning plate 11 to embed downward into the frame body, ensuring that the limiting frames 14 can smoothly limit the position of the positioning plate 11, and two positioning blocks 15 are symmetrically installed on the top of each limiting frame 14. The two positioning blocks 15 limit the positioning plate 11 synchronously, further ensuring the limiting effect on the positioning plate 11.
[0049] As a preferred embodiment of the present invention, the transmission plates 17 are symmetrically arranged on the top of the cover 10, and a plurality of reinforcing ribs 18 are installed at equal intervals at the bottom of each transmission plate 17. Sliding grooves 19 adapted to the transmission plates 17 and the reinforcing ribs 18 are opened on the cover 10 and the positioning plate 11, and the reinforcing ribs 18 and the transmission plates 17 can only move laterally on the sliding grooves 19 under the limitation of the sliding grooves 19, and cannot be directly pulled out from the sliding grooves 19. The sliding of the reinforcing ribs 18 and the transmission plates 17 along the sliding grooves 19 can maintain a stable state during the movement of the transmission plates 17;
[0050] The top corners of the adjacent outer walls of the two transmission plates 17 are both designed with bevels, and the top surface of the transmission plate 17 and the top surface of the boss 63 are located on the same plane, ensuring that the transmission plates 17 will not affect the normal use of the rubber blocks 7, and can smoothly slide to the lower part of the rubber blocks 7 when the rubber blocks 7 are subsequently disassembled.
[0051] As a preferred embodiment of the present invention, the pulling mechanism comprises an unlocking rod 25 slidably installed on the top of the cover 10, and pull ropes 24 located inside the cover 10 and connected to both ends of the transmission plates 17 are installed on the outer walls of both sides of the unlocking rod 25; a pull handle 26 located above the unlocking rod 25 is installed on the top of the cover 10, and pulling the unlocking rod 25 to move upward will synchronously pull the pull ropes 24 on both sides of the unlocking rod 25 to drive the transmission plates 17 to slide.
[0052] In a preferred embodiment of the present invention, a horizontal roller 27 is detachably installed on the frame 1, and an extension frame 28 is installed at each end of the cover 10. A vertical roller 29 that cooperates with the horizontal roller 27 is rotatably installed at the end of the extension frame 28. The horizontal roller 27 supports the bottom of the cable, and the vertical roller 29 can limit the lateral displacement of the cable.
[0053] As a preferred embodiment of the present invention, a tensioning mechanism may be added to the outer wall of the cover 10. The tensioning mechanism includes an adjusting rod 30 rotatably mounted on the outer wall of the cover 10, and the end of the adjusting rod 30 is threadedly connected to a slide 31 slidably mounted on the cover 10. At the same time, a plurality of tensioning wheels 32 that are in contact with the rubber block 7 are rotatably mounted on the inner end of the slide 31. By rotating the adjusting rod 30, the slide 31 can be moved laterally to adjust the contact distance between the tensioning wheels 32 and the rubber block 7.
[0054] Working principle: Under normal cable traction conditions, the drive wheel 3 drives the track 4 to move in a circular motion. The reinforcing rod 5 and support 61 fixed on the track 4 move synchronously with the track 4. In this state, the locking block 6 at the top of the reinforcing rod 5 is inserted into the locking groove 60 at the bottom of the rubber block 7, while the connecting ear 8 at the end of the rubber block 7 is slidably assembled on the top of the reinforcing rod 5.
[0055] During the movement of the track 4, the reinforcing rod 5, the clamping block 6, the clamping groove 60, and the docking ear 8 synchronously drive all the rubber blocks 7 to rotate together. The rubber blocks 7 on both sides clamp the cable sheath and rely on the friction of the contact surface to complete the long-distance cable pulling and conveying operation. During this process, the horizontal roller 27 mounted on the frame 1 forms a lifting support for the bottom of the cable. The two sets of vertical rollers 29 rotatably installed at the end of the extension frame 28 respectively fit the left and right sides of the cable, limiting the left and right lateral deviation during the cable conveying process and reducing the lateral friction loss between the cable sheath and the edge of the rubber block 7.
[0056] During continuous operation of track 4, the ball bearing 62 mounted at the bottom of support 61 will roll and cooperate with the boss 63 on the top surface of track frame 2. The boss 63, ball bearing 62, support 61, and reinforcing rod 5 cooperate with each other to form a stable support for track 4, rubber block 7 and cable load, share the longitudinal compressive stress generated by traction operation, reduce the long-term pressure wear of track 4, and extend the overall service life of track 4.
[0057] Meanwhile, multiple sets of ball bearings 13 at the bottom of the inner pressure frame 12 of the cover 10 will roll against the top surface of the rubber block 7, limiting the top of the rubber block 7 while reducing sliding friction resistance. If the cover 10 is equipped with a tensioning mechanism, rotating the adjusting rod 30 before use will cause the adjusting rod 30 to drive the slide 31 to move laterally under the action of the thread, so that multiple sets of tensioning wheels 32 on the inner side of the slide 31 will fit against the outer wall of the rubber block 7 to adjust the tension.
[0058] In operation, the positioning plate 11 is located inside the top limiting frame 14 of the track frame 2, and the top positioning block 15 of the limiting frame 14 is pressed against the top surface of the positioning plate 11 under the action of the spring 16, thereby locking the assembly position of the cover 10.
[0059] At the same time, the spring 22 inside the sliding box 21 is in contact with the transmission ear 20, so that the transmission ear 20 and the transmission plate 17 are kept away from the boss 63. At this time, the unlocking frame 23 is located on the side of the positioning block 15, and the unlocking rod 25 is naturally placed below the handle 26.
[0060] When the rubber block 7 wears out due to long-term friction and needs to be replaced in batches, if a tensioning mechanism is installed on the cover 10, first rotate the adjusting rod 30 to adjust the tensioning wheel 32 to a position away from the rubber block 7. Then, pull the unlocking rod 25 on the top of the cover 10 upwards to move the unlocking rod 25 upwards. It will simultaneously pull the pull rope 24 connected on both sides, so that the pull rope 24 pulls the two sets of transmission plates 17 to slide along the slide groove 19 opened on the cover 10 and the positioning plate 11 towards the boss 63. During this process, the reinforcing rib 18 at the bottom of the transmission plate 17 will be guided to move synchronously along the slide groove 19 until the transmission plate 17 slides to the limit position of the slide groove 19, and both sets of transmission plates 17 move to the bottom of the rubber block 7.
[0061] During the sliding process of the transmission plate 17, the transmission plate 17 will drive the transmission ear 20 to move synchronously, so that the transmission ear 20 enters the sliding box 21 and compresses the second spring 22. The unlocking bracket 23 at the end of the transmission plate 17 will move synchronously, so that the end of the unlocking bracket 23 will continuously press the outer oblique angle of the positioning block 15, forcing the positioning block 15 to overcome the pushing force of the first spring 16 and slide laterally away from the cover 10. After the transmission plate 17 reaches the sliding limit, the positioning block 15 is misaligned with the top surface of the positioning plate 11, that is, the locking constraint on the positioning plate 11 is released. In this state, the top surface of the unlocking rod 25 is in contact with the top and bottom surfaces of the handle 26.
[0062] Next, continue to lift the unlocking lever 25 upwards, causing the handle 26 to pull the cover 10 upwards. This causes the cover 10 to move upwards through the positioning plate 11, which in turn drives the two transmission plates 17 to move upwards synchronously. During this process, the top surface of the transmission plate 17 directly lifts multiple sets of rubber blocks 7 as a whole. Since the end lugs 8 of each set of rubber blocks 7 are connected in series by steel ropes 9, all the rubber blocks 7 are simultaneously removed from above the track 4 along with the cover 10 during the lifting process. This enables the batch disassembly of the rubber blocks 7, eliminating the step of loosening and unfastening each fastener individually, and significantly reducing the disassembly time.
[0063] After the rubber block 7 is removed and moved to the placement position, the pulling force on the unlocking rod 25 is released, so that the tension on the pull rope 24 is eliminated simultaneously. The unlocking rod 25 falls back down under its own weight. At the same time, the spring 22 rebounds and pushes the transmission ear 20 and the transmission plate 17 to move back along the slide groove 19, causing the transmission plate 17 to be removed from the bottom of the rubber block 7. At this time, the rubber block 7 loses its support and can slide directly from the inside of the cover 10 to separate.
[0064] When assembling the new rubber block 7, the position of the new rubber block 7 can be adjusted by taking the steel rope 9. Then, the end of the rubber block 7 is aligned with the top of the reinforcing rod 5 on the track 4 to complete the sliding connection. Since the length of the reinforcing rod 5 protruding upward from the track 4 is greater than the length of the locking block 6, and the rubber block 7 can only move up and down along the reinforcing rod 5 after the end of the locking lug 8 is fitted, then the rubber block 7 can be directly engaged with the locking block 60 at the bottom of the rubber block 7 by pressing down. The quick snap-fit assembly is achieved by relying on the chamfer guide, reducing the difficulty of manual alignment assembly.
[0065] After the rubber block 7 is assembled, hold the handle 26 and place the cover 10 downwards above the track frame 2. During this process, the positioning plate 11 will extend into the limiting frame 14, so that the bottom surface of the positioning plate 11 contacts the top inclined surface of the positioning block 15 and continues to press down, forcing the positioning block 15 to slide again towards the spring 16 and compress the spring 16. When the positioning plate 11 is fully embedded in the limiting frame 14 and the bottom surface is attached to the top surface of the track frame 2, the side wall of the positioning plate 11 no longer forms a squeezing constraint on the positioning block 15. The spring 16 rebounds and pushes the positioning block 15 to reset, so that the positioning block 15 re-attaches to the top surface of the positioning plate 11 to lock the cover 10. The replacement process of all rubber blocks 7 is completed.
[0066] The adhesive block 7 can be disassembled and installed in batches, greatly reducing equipment downtime, ensuring continuous progress of long-distance cable traction construction, and effectively improving the overall efficiency of cable laying operations.
