Description

Technical Field

[0001] This utility model belongs to the field of cable splicing support technology, and specifically relates to a cable support device for a power cable splice joint. Background Technology

[0002] In the laying and connection of power cables, cable splicing is a crucial operational step. Cable support devices, as key equipment assisting in cable splicing, directly affect the quality and efficiency of cable splicing due to their performance and rational design.

[0003] Currently, existing cable support devices have many shortcomings in practical applications. Regarding cable support, traditional support devices have relatively fixed support structures, and the placement angle of the support columns is difficult to adjust flexibly. When supporting cables at different positions or angles, workers often need to frequently and deliberately adjust the placement angle of the support columns. This not only increases the complexity and labor intensity of the operation but also easily leads to inaccurate support positions, affecting the stable support of the cable and consequently adversely affecting subsequent cable splicing operations. Regarding cable clamping, due to the differences in diameter of different power cables, existing support devices often cannot effectively clamp cables of different diameters. This necessitates frequent replacement of different specifications of support devices during cable splicing operations, significantly reducing work efficiency and increasing construction costs. Utility Model Content

[0004] The purpose of this invention is to provide a cable support device for power cable fusion splice joints to solve the problems of flexible adjustment and cable variety clamping in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable support device for a power cable fusion splice includes a support column, a rotating shaft movably connected inside the support column, an upper plate at the top of the rotating shaft, a sleeve on the surface of the upper plate, and a locking post detachably connected inside the sleeve; support devices for supporting the cable are provided on both sides of the locking post.

[0007] Preferably, the sleeve has symmetrical grooves on both sides, and the retaining post has extension rods on both sides that fit into the grooves. The extension rods extend out of the grooves, so that the retaining post inside the sleeve can be removed by applying force through the extension rods, improving the ease of disassembly. The plug-in installation method improves the assembly effect.

[0008] Preferably, clamping rings are provided on both sides of the locking post away from the extension rod, and the clamping rings are matched with the wall thickness of the sleeve. The support device is disposed on the outer wall of the clamping rings. The matching of the clamping rings with the sleeve wall thickness can further improve the installation stability of the locking post.

[0009] Preferably, the support device includes a support arm and a mounting rod. The support arm is fixed to the outer wall of the clamping ring, and the mounting rod is movably installed inside the support arm. A chuck is fixed to one side of the mounting rod, and the surface of the chuck has several keyways equidistantly spaced. A movable disk is sleeved on one end of the mounting rod, and a number of key blocks that mate with the keyways are provided on one side of the movable disk. Several extension arms are equidistantly surrounded on the outer wall of the movable disk, and a lower retaining ring is fixed to the top of the extension arm. An upper retaining ring is hinged to the lower retaining ring.

[0010] Preferably, the inner walls of the upper and lower retaining rings are provided with inner lining pads, and the diameter of the inner lining pads on each set of upper and lower retaining rings is different.

[0011] Preferably, the tail end of the mounting rod is provided with a threaded groove, a top block is installed inside the threaded groove, and a spring is sleeved on the tail end of the mounting rod.

[0012] Preferably, the inner liner is made of rubber. The rubber inner liner enhances the contact friction with the cable, improving the cable's support stability.

[0013] The technical solution of this utility model has the following beneficial effects:

[0014] 1. The locking column can rotate together with the rotating shaft, which allows the support devices on both sides of the locking column to rotate flexibly and adjust the support position, improving the flexibility of the entire support device and eliminating the need to frequently and deliberately adjust the placement angle of the support column.

[0015] 2. The inner lining pads on each set of upper and lower clamping rings have different diameters, so they can clamp cables of different diameters, meeting the clamping needs of various cable specifications and improving work efficiency and versatility.

[0016] 3. When rotating and adjusting the movable plate, push the movable plate towards the spring square. The spring generates compression and stores potential energy. After the key block of the movable plate disengages from the keyway of the chuck, rotate the movable plate to adjust the other lower retaining rings to be perpendicular to the ground. Each adjustment ensures that one lower retaining ring is always perpendicular to the ground, meaning that the key block and keyway can fully fit together. After adjusting the position, release the pushing force on the movable plate. The spring releases the stored potential energy, allowing the key block to engage and fix itself inside the keyway. The adjustment method is convenient. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] Example 1:

[0028] refer to Figures 1-3 A cable support device for a power cable fusion splice joint includes a support column 10, a rotating shaft 20 movably connected inside the support column 10, and an upper plate 201 on the top of the rotating shaft 20.

[0029] The upper plate 201 has a sleeve 202 on its surface, and a locking post 30 is detachably connected inside the sleeve 202. The locking post 30 has a support device on both sides for supporting the cable.

[0030] In the above scheme, the bottom of the support column 10 is surrounded by corner braces 101 at equal intervals. The support column 10 is placed directly on the ground, and the corner braces 101 provide auxiliary support and improve the stability of the support column 10. The rotating shaft 20 can rotate 360° inside the support column 10. Therefore, the locking column 30 is installed in the sleeve 202. The locking column 30 can rotate with the rotating shaft 20, so that the support devices on both sides of the locking column 30 can flexibly rotate and adjust the support position, improving the flexibility of the entire support device and eliminating the need to frequently and deliberately adjust the placement angle of the support column 10.

[0031] In a preferred embodiment, the sleeve 202 has symmetrical grooves 203 on both sides, and the locking post 30 has extension rods 301 on both sides that match the grooves 203;

[0032] Clamping rings 302 are provided on both sides of the clamping post 30 away from the extension rod 301. The clamping rings 302 and the sleeve 202 have the same wall thickness. The support device is set on the outer wall of the clamping rings 302.

[0033] In the preferred embodiment, the extension rod 301 cooperates with the groove 203 to prevent the locking pin 30 from rotating inside the sleeve 202. The extension rod 301 extends beyond the groove 203, allowing the locking pin 30 to be removed from the sleeve 202 under pressure, improving the ease of disassembly. The plug-in installation method enhances assembly efficiency. The clamping ring 302 matches the wall thickness of the sleeve 202, further improving the installation stability of the locking pin 30.

[0034] refer to Figures 1-7 The support device includes a support arm 3031 and a mounting rod 303. The support arm 3031 is fixed to the outer wall of the clamping ring 302. The mounting rod 303 is movably installed inside the support arm 3031. A chuck 304 is fixed to one side of the mounting rod 303. Several keyways 305 are equidistantly spaced on the surface of the chuck 304. A movable disk 40 is sleeved on one end of the mounting rod 303. Several key blocks 401 that cooperate with the keyways 305 are provided on one side of the movable disk 40. Several extension arms 402 are equidistantly surrounded on the outer wall of the movable disk 40. A lower retaining ring 403 is fixed to the top of the extension arm 402. An upper retaining ring 404 is hinged to the lower retaining ring 403.

[0035] In the above scheme, the upper retaining ring 404 is rotated open, the cable to be welded is placed into the lower retaining ring 403, and the upper retaining ring 404 is rotated again to close onto the lower retaining ring 403. The upper retaining ring 404 and the lower retaining ring 403 support and fix the cable. In the figure, the ends of the upper retaining ring 404 and the lower retaining ring 403 away from the hinge connection are provided with a structure for installing a bolt. A bolt is connected at this point to press the upper retaining ring 404 onto the lower retaining ring 403, thus completing the clamping of the cable. The mounting rod 303 is movably installed in the support arm 3031. The working distance of the mounting rod 303 can be adjusted by pulling it according to the usage needs. A nut 70 is provided on the side of the support arm 3031. The working distance of the mounting rod 303 is adjusted by tightening or loosening the nut 70. The cooperation between the keyway 305 and the key block 401 can prevent the movable plate 40 from automatically rotating and misaligning during use, and stabilize the position of the movable plate 40. The sleeved movable plate 40 can also be easily disassembled and replaced.

[0036] In practical use: one extension arm 402 is always kept perpendicular to the ground. When there is only one cable, the cable is placed on the lower clamping ring 403 that is perpendicular to the ground for clamping. At the same time, multiple cables can also be clamped on other lower clamping rings 403, which has good versatility, whether it is a single cable or multiple cables, to facilitate the clamping and welding of power cable joints. (It should be noted that the clamping of multiple cables only involves the upper half of the movable disc 40, which makes it easier to expose the cables and facilitate welding.)

[0037] Example 2:

[0038] refer to Figures 1-6 The inner walls of the upper retaining ring 404 and the lower retaining ring 403 are provided with inner lining pads 405, and the diameter of the inner lining pads 405 on each set of upper retaining ring 404 and lower retaining ring 403 is different.

[0039] The end of the mounting rod 303 is provided with a threaded groove 306, and a top block 50 is installed inside the threaded groove 306. A spring 60 is sleeved on the end of the mounting rod 303.

[0040] In the preferred embodiment, for the splicing of a single cable, it is only necessary to place the cable into the lower clamping ring 403 perpendicular to the ground for clamping. The inner lining pads 405 on each set of upper clamping rings 404 and lower clamping rings 403 have different diameters, so clamping operations can be performed on cables of different diameters, which can meet the clamping requirements of various specifications of cables, improve work efficiency and versatility.

[0041] Specifically, when the movable disk 40 needs to be rotated and adjusted, it is pushed squarely towards the spring 60. The spring 60 generates compressed and stored potential energy. After the key block 401 of the movable disk 40 disengages from the key groove 305 of the chuck 304, the movable disk 40 is rotated to adjust the other lower retaining rings 403 to be perpendicular to the ground. In each adjustment, one lower retaining ring 403 is always perpendicular to the ground, that is, the key block 401 and the key groove 305 can be completely matched. After the position is adjusted, the pushing force on the movable disk 40 is released, and the spring 60 releases the stored potential energy, so that the key block 401 can be engaged and fixed inside the key groove 305. The adjustment method is convenient.

[0042] Furthermore, the inner liner 405 is made of rubber. The rubber inner liner 405 can enhance the contact friction with the cable and improve the cable's support stability.

[0043] The specific implementation process of this utility model is as follows:

[0044] A nut 70 is provided on the side of the support arm 3031, and the working distance of the mounting rod 303 is adjusted by tightening or loosening the nut 70. Rotate to open the upper retaining ring 404, put the cable to be welded into the lower retaining ring 403, and rotate the upper retaining ring 404 again to close it on the lower retaining ring 403. The upper retaining ring 404 and the lower retaining ring 403 support and fix the cable.

[0045] For splicing a single cable, the inner lining 405 on each set of upper retaining rings 404 and lower retaining rings 403 has a different diameter, thus allowing for clamping operations on cables of different diameters. When rotating and adjusting the movable disc 40, the movable disc 40 is pushed squarely towards the spring 60, which generates compressed and stored potential energy. Once the key block 401 of the movable disc 40 is disengaged from the keyway 305 of the chuck 304, the movable disc 40 is rotated to adjust the other lower retaining rings 403 to be perpendicular to the ground. In each adjustment, one lower retaining ring 403 is always perpendicular to the ground, meaning that the key block 401 and the keyway 305 can be fully engaged. After adjusting the position, the pushing force on the movable disc 40 is released, and the spring 60 releases its stored potential energy, allowing the key block 401 to be locked inside the keyway 305.
