Description

Technical Field

[0001] This utility model relates to the field of electrothermal fusion sleeve repair welding technology, and more specifically, it relates to an electrothermal fusion sleeve repair welding device. Background Technology

[0002] In existing technologies, thermofusion welding machines are key tools and equipment in pipeline connection construction. Their working principle is to melt the thermofusion material inside the thermofusion sleeve at high temperatures, forming a strong molecular-level bond with the pipe surface. In existing technologies, one end of the cable is usually connected to the thermofusion welding machine first, and then the other end is connected to the connector on the outside of the thermofusion sleeve for welding. This connection method is the basic link for energy transfer. However, the connection and disconnection operations between the cable and the thermofusion welding machine in existing technologies are usually cumbersome and complex, lacking user-friendly design. During operation, it is often necessary to use a variety of professional tools such as screwdrivers, wrenches, and Allen wrenches for assistance. This not only increases the burden of carrying tools, but also requires operators to have a high level of technical skills and proficiency. This complex connection method is particularly inconvenient in field construction environments, especially when working in harsh weather conditions or confined spaces, where the difficulty of operation increases significantly, maintenance costs increase, and preparation and completion times for each construction project are extended, significantly reducing work efficiency and bringing adverse effects.

[0003] Secondly, while some improved equipment has achieved convenient connection and disconnection of cables and hot melt welding machines to address the aforementioned issues, simplifying the operation process, shortening connection time, and improving on-site construction efficiency to some extent, its structural design is too simple and crude, with insufficient overall mechanical strength, low stability, and a lack of reliable anti-loosening design. In actual construction sites, hot melt welding is often accompanied by significant interference. These physical factors can easily cause the cable clamping components to move unexpectedly or deviate from their position. This connection instability is particularly dangerous during welding, as welding typically requires continuous and stable current and precise time control. Once the connection becomes loose or interrupted, it will not only lead to substandard welding quality and safety hazards such as interface leakage, but may also damage the internal circuitry of the hot melt welding machine due to sudden current changes, resulting in unstable cable connections or even complete connection failure. More seriously, in large-scale engineering projects, such connection failure may delay the construction progress of the entire pipeline, increase manpower and material costs, and even affect the completion and acceptance of the entire project, resulting in serious economic losses and project delays, and causing adverse effects.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an electrothermal fusion sleeve repair welding device, which has the following beneficial effects:

[0017] 1. The cable clamping device consists of a user sleeve, an inlet sleeve, a fixed sleeve, a moving block, a movable sleeve, a movable slot, a movable block, a movable plate, and a movable slot. It employs an innovative mechanical transmission principle combining spiral drive and inclined slot guidance, completely solving the technical problems of cumbersome cable connection and complex operation in traditional hot melt welding machines. The rotating connection design of the user sleeve with the inlet sleeve and fixed sleeve, combined with the precise sliding mechanism of the movable block in the spiral movable slot, constructs an efficient and convenient cable clamping and release system, allowing operators to quickly connect and disconnect cables without any tools. The ingenious cooperation between the movable sleeve and the movable block, guided by the inclined movable slot... It precisely converts rotational motion into radial clamping force, ensuring stable cable connection under various working conditions.

The rotational locking design of the adapter plate and adapter slot, combined with the precise fit of the clamping sleeve and clamping plate, constructs a highly reliable mechanical locking system, ensuring that the cable clamping device maintains a stable locked state under various vibration and impact conditions during the welding process. The elastic connection of the clamping spring to adjacent clamping blocks, coupled with the precise meshing of the clamping wheel and clamping block, forms a multi-level anti-loosening protection mechanism, effectively preventing potential loosening caused by prolonged use and frequent adjustments.

The movable slot 10 is spirally opened on the inner wall of the sleeve 2. A clamping mechanism is provided on the outer side of the inlet sleeve 3. The clamping mechanism includes an adapter slot 11, a clamping sleeve 12, a clamping spring 13, a clamping block 14, a connecting plate 15, a clamping plate 16, an adapter plate 17, and a clamping block 18. The adapter slot 11 is opened on the adapter plate 17. The clamping sleeve 12 is slidably installed on the outer side of the inlet sleeve 3. The two ends of the clamping spring 13 are respectively connected to two adjacent clamping blocks 14. The connecting plate 15 is fixedly installed on one side of the clamping sleeve 12. Three clamping plates 16 are fixedly installed on one side of the connecting plate 15. The adapter plate 17 is rotatably installed on the outer side of the inlet sleeve 3. Multiple clamping blocks 18 are fixedly installed on the outer side of the inlet sleeve 3.

[0029] The hot melt welding machine 1 has a detachable handle 19 at the top.

[0030] In this embodiment, when it is necessary to disconnect one end of the cable from the hot melt welding machine 1, firstly, the adapter plate 17 is rotated, causing the adapter plate 17 to drive the adapter groove 11 and the thrust bearing 24 installed on one side to rotate. Then, the adapter plate 17 will drive the adapter groove 11 to rotate to the position corresponding to the clamping plate 16, and then push the clamping sleeve 12. The clamping sleeve 12 will drive the connecting plate 15 and the clamping plate 16 to gradually slide through the adapter groove 11, and the clamping sleeve 12 will cooperate with the thrust bearing 24 to compress the movable spring 25. When the movable spring 25 is compressed to its limit, the part closest to the clamping sleeve 12 will be compressed. One of the clamping plates 16 passes through the adapter groove 11 and moves to the other side of the adapter plate 17. Then, the adapter plate 17 is rotated again, causing the adapter plate 17 to rotate the adapter groove 11 to a position that does not correspond to the clamping plate 16. Then, the connecting plate 15 and the clamping plate 16 closest to the clamping sleeve 12 cooperate to limit the clamping sleeve 12 to one side of the adapter plate 17, so that the inner wall of the clamping sleeve 12 no longer limits the outer wall of the clamping wheel 26. Then, the sleeve 2 is rotated in the forward direction. The sleeve 2, through the clamping rail 20 on one side and the clamping groove 21, drives the clamping block 14 to rotate in the forward direction. The clamping block 14 causes one clamping wheel 26 to roll out from between the two clamping blocks 18. Then, the clamping wheel 26 causes the clamping block 14 to slide outward along the clamping rail 20 and the clamping groove 21. The clamping block 14 also causes the clamping spring 13 to stretch outward. At the same time, the sleeve 2 causes the inner spirally opened moving groove 10 to rotate in the forward direction. Then, the moving block 5 slides in the moving groove 10. Due to the limiting rail 27 and the limiting groove 28 limiting the moving sleeve 6, the moving sleeve 6 will not rotate. Then, the moving block 5 will cause the moving sleeve 6 to slide along the limiting rail 27 and the limiting groove 28. The groove 28 slides, and during this process, the spring 23 on one side of the mating plate 22 resets and pushes the movable block 8 to slide, so that the movable block 8 drives the movable plate 9 on one side to slide along the inclined movable groove 7, so that one side of the movable block 8 is always in contact with one side of the movable sleeve 6, and the movable plate 9 drives the movable block 8 to move outward while sliding outward along the movable groove 7, so that the movable block 8 drives the rubber plate 29 on one side to move outward. Then the movable block 8 no longer clamps the outer wall of the cable through the inner wall of the rubber plate 29, and then one end of the cable can be removed from the side of the hot melt welding machine 1.

[0031] Please see Figures 3-5 As a further implementation of the overall equipment: a plurality of clamping rails 20 are fixedly provided on one side of the sleeve 2, and a clamping groove 21 is provided in the clamping block 14. The clamping block 14 is slidably installed on one side of the clamping rail 20 through the clamping groove 21.

[0032] A mating plate 22 is fixedly provided on the inner side of the inlet sleeve 3. A mating spring 23 is connected to one side of the mating plate 22, and the other end of the mating spring 23 is connected to the movable block 8.

[0033] A thrust bearing 24 is detachably provided on one side of the adapter plate 17. One end of the thrust bearing 24 is connected to a movable spring 25, and the other end of the movable spring 25 is connected to the clamping sleeve 12.

[0034] A clamping wheel 26 is provided on one side of the clamping block 14, which is rotated and engages between the two clamping blocks 18.

[0035] Multiple limiting rails 27 are fixedly provided on the inner side of the fixed sleeve 4, and multiple limiting grooves 28 are provided on the outer side of the movable sleeve 6. The limiting grooves 28 are adapted to the limiting rails 27.

[0036] A rubber plate 29 is connected to one side of the movable block 8.

[0037] More specifically, when it is necessary to connect one end of the cable to the hot melt welding machine 1, first, the cable is threaded through the inlet sleeve 3 and connected to the hot melt welding machine 1. Then, the sleeve 2 is rotated in the reverse direction, so that the sleeve 2, through the cooperation of the clamping rail 20 and the clamping groove 21, drives the clamping block 14 and the clamping wheel 26 to rotate in the reverse direction. At the same time, the sleeve 2 will drive the inner moving groove 10 to rotate in the reverse direction. Then, the moving block 5 will drive the moving sleeve 6 to slide in the reverse direction along the limiting rail 27 and the limiting groove 28. Then, the moving sleeve 6 will push the movable block 8 on one side to slide in the reverse direction, so that the movable block 8... The movable block 8 drives the rubber plate 29 to slide in the opposite direction, and the movable block 8 also drives one side of the movable plate 9 to slide in the opposite direction along the movable groove 7. As the movable plate 9 slides in the movable groove 7, it drives the movable block 8 to move inward, so that the movable block 8 clamps the cable through the inner rubber plate 29. At this time, the clamping rail 20 and the clamping groove 21 cooperate to move the clamping block 14 between the two corresponding clamping blocks 18. Then, the clamping spring 13 resets and pulls the clamping block 14 to slide inward along the clamping rail 20 and the clamping groove 21, so that the clamping block 14 drives one side of the cable to move inward. The tensioning wheel 26 engages between the two corresponding locking blocks 18. Then, the adapter plate 17 is rotated again, causing the adapter plate 17 to drive the adapter groove 11 and the thrust bearing 24 on one side to rotate again. When the adapter groove 11 rotates to the position corresponding to the locking plate 16, the movable spring 25 resets and pushes the locking sleeve 12 to slide reset. Then, the locking sleeve 12 drives the three locking plates 16 to slide reset through the connecting plate 15 on one side. When the movable spring 25 is fully reset, the other two locking plates 16 move to the sides of the adapter plate 17 respectively. Then, the adapter plate 17 is rotated again. 7. This causes the adapter plate 17 to rotate again, driving the adapter groove 11 and the thrust bearing 24 on one side. This causes the adapter plate 17 to rotate and reset the adapter groove 11 to a position that does not correspond to the clamping plate 16. Then, the connecting plate 15 and the two clamping plates 16 cooperate to limit and support the clamping sleeve 12 to one side of the adapter plate 17. Then, the inner wall of the clamping sleeve 12 limits the outer wall of the clamping wheel 26, so that the clamping wheel 26 and the clamping block 14 cannot move. This achieves rotational limitation of the sleeve 2, ensuring stable clamping of the cable and ensuring that the welding work can be carried out stably.

[0038] In summary, during the use or operation of the overall equipment: when it is necessary to disconnect one end of the cable from the hot melt welding machine 1, firstly rotate the adapter plate 17, causing the adapter plate 17 to drive the adapter slot 11 and the thrust bearing 24 installed on one side to rotate. Then, the adapter plate 17 will drive the adapter slot 11 to rotate to the position corresponding to the clamping plate 16, and then push the clamping sleeve 12. The clamping sleeve 12 will drive the connecting plate 15 and the clamping plate 16 to gradually slide through the adapter slot 11, and the clamping sleeve 12 will cooperate with the thrust bearing 24 to compress the movable spring 25. When the movable spring 25 is compressed to its limit, The clamping plate 16 closest to the clamping sleeve 12 passes through the adapter groove 11 and moves to the other side of the adapter plate 17. Then, the adapter plate 17 is rotated again, causing the adapter plate 17 to rotate the adapter groove 11 to a position that does not correspond to the clamping plate 16. Then, the connecting plate 15 and the clamping plate 16 closest to the clamping sleeve 12 cooperate to limit the clamping sleeve 12 to one side of the adapter plate 17, so that the inner wall of the clamping sleeve 12 no longer limits the outer wall of the clamping wheel 26. Then, the sleeve 2 is rotated in the forward direction. The sleeve 2, through the clamping rail 20 on one side and the clamping groove 21, drives the clamping block 14 to rotate in the forward direction. Rotation causes the locking block 14 to drive the locking wheel 26 on one side to roll out from between the two locking blocks 18. The locking wheel 26 then drives the locking block 14 to slide outwards along the locking rail 20 and locking groove 21, while the locking block 14 drives the locking spring 13 to stretch outwards. Simultaneously, the sleeve 2 causes the inner spirally opened moving groove 10 to rotate forward, and the moving block 5 slides in the moving groove 10. Due to the limiting rail 27 and limiting groove 28 limiting the moving sleeve 6, the moving sleeve 6 will not rotate. Then, the moving block 5 drives the moving sleeve 6 to slide along the limiting rail 27. The movable block 8 slides with the limiting groove 28. During this process, the spring 23 on one side of the mating plate 22 resets and pushes the movable block 8 to slide, so that the movable block 8 drives the movable plate 9 on one side to slide along the inclined movable groove 7, so that one side of the movable block 8 is always in contact with one side of the movable sleeve 6. While the movable plate 9 slides outward along the movable groove 7, it drives the movable block 8 to move outward, so that the movable block 8 drives the rubber plate 29 on one side to move outward. Then the movable block 8 no longer clamps the outer wall of the cable through the inner wall of the rubber plate 29, and then one end of the cable can be removed from the side of the hot melt welding machine 1.

[0039] When it is necessary to connect one end of the cable to the hot melt welding machine 1, first insert the cable into the inlet sleeve 3 and connect it to the hot melt welding machine 1. Then, rotate the sleeve 2 in the reverse direction, so that the sleeve 2, through the cooperation of the clamping rail 20 and the clamping groove 21, drives the clamping block 14 and the clamping wheel 26 to rotate in the reverse direction. At the same time, the sleeve 2 will drive the inner moving groove 10 to rotate in the reverse direction. Then, the moving block 5 will drive the moving sleeve 6 to slide in the reverse direction along the limiting rail 27 and the limiting groove 28. Then, the moving sleeve 6 will push the movable block 8 on one side to slide in the reverse direction, so that the movable block 8... The movable rubber plate 29 slides in the opposite direction, and the movable block 8 drives one side of the movable plate 9 to slide in the opposite direction along the movable groove 7. While the movable plate 9 slides in the movable groove 7, it drives the movable block 8 to move inward, so that the movable block 8 clamps the cable through the inner rubber plate 29. At this time, the clamping rail 20 and the clamping groove 21 cooperate to drive the clamping block 14 to move between the two corresponding clamping blocks 18. Then, the clamping spring 13 resets and pulls the clamping block 14 to slide inward along the clamping rail 20 and the clamping groove 21, so that the clamping block 14 drives one side of the clamping wheel 2. 6. Insert the clip into the corresponding two clips 18, then rotate the adapter plate 17 again, causing the adapter plate 17 to drive the adapter groove 11 and the thrust bearing 24 on one side to rotate again. When the adapter groove 11 rotates to the position corresponding to the clip 16, the movable spring 25 resets and pushes the clamping sleeve 12 to slide reset. Then, the clamping sleeve 12 drives the three clips 16 to slide reset through the connecting plate 15 on one side. When the movable spring 25 is fully reset, the other two clips 16 have just moved to the two sides of the adapter plate 17 respectively. Then rotate the adapter plate 17 again. This causes the adapter plate 17 to rotate again, driving the adapter groove 11 and the thrust bearing 24 on one side. This causes the adapter plate 17 to rotate and reset the adapter groove 11 to a position that does not correspond to the clamping plate 16. Then, the connecting plate 15 and the two clamping plates 16 cooperate to limit and support the clamping sleeve 12 to one side of the adapter plate 17. Then, the inner wall of the clamping sleeve 12 limits the outer wall of the clamping wheel 26, making the clamping wheel 26 and the clamping block 14 unable to move. This achieves rotation limit of the sleeve 2, ensuring stable clamping of the cable and ensuring that the welding work can be carried out stably.
