Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of hardware technology, and more specifically, to a repair-type splicing hardware. Background Technology

[0002] In the construction of power transmission and communication networks, overhead cables serve as a key physical connection medium, undertaking the important mission of power transmission and signal transmission. However, due to their long-term exposure to complex and ever-changing natural environments and potential human interference factors, the risk of cable damage always exists.

[0003] Severe weather conditions in the natural environment, such as strong winds, heavy rain, blizzards, freezing temperatures, and typhoons, can cause tree branches to fall and crush cables, and towers to tilt and pull on cables, resulting in varying degrees of breakage and wear on the cables. At the same time, with the acceleration of urban construction and the frequent implementation of various engineering construction activities, human factors such as accidental contact with construction machinery and damage to underground cables during excavation operations have further increased the probability of cable damage.

[0004] When cable faults occur, timely and efficient emergency repairs are crucial to ensuring stable power supply and uninterrupted communication networks. In traditional cable repair operations, the splicing hardware used has many problems that urgently need to be solved. Some splicing hardware has a complex structural design and a cumbersome installation process, requiring high professional skills from repair personnel, which leads to extended repair time and fails to meet the actual need for rapid restoration of line operation.

[0005] Some splicing fittings have insufficient or uneven clamping force when holding cables, which can easily cause the cables to loosen, affecting the stability and conductivity of the line connection and potentially leading to secondary faults. In addition, existing splicing fittings have poor versatility when dealing with cables of different specifications and materials, requiring the preparation of multiple models of fittings, which increases the cost of emergency repairs and the difficulty of material management. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a repair-type splicing fitting, which solves the problem that in related technologies / prior technologies, when the fittings clamp the cable, the clamping force is insufficient or unevenly distributed, which easily leads to the cable loosening, affecting the stability and conductivity of the line connection, and may cause secondary faults. In addition, existing splicing fittings have poor versatility when dealing with cables of different specifications and materials, requiring the preparation of multiple models of fittings, which increases the cost of emergency repairs and the difficulty of material management.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] like Figures 1-4 As shown, it illustrates a repair-type splicing fitting according to an embodiment of this disclosure, comprising:

[0037] A clamping base sleeve 1 is provided with a support frame 2 at its bottom;

[0038] Drive clamping component 3, which is located at the upper end of clamping base sleeve 1;

[0039] Support counterweight assembly 4 is mounted on support frame 2;

[0040] The drive clamping assembly 3 includes a force-bearing plate 3-1, which is disposed on opposite sides of the clamping base sleeve 1. The clamping base sleeve 1 has a clamping groove 3-2 inside, and an anti-slip pad 3-3 is disposed inside the clamping groove 3-2. The force-bearing plate 3-1 has an insertion hole 3-4, and a drive rod 3-5 is inserted into the insertion hole 3-4. A clamping plate 3-6 is fitted onto the drive rod 3-5. A clamping sleeve 3-7 is disposed on the side wall of the clamping plate 3-6. The clamping sleeve 3-7 is spliced ​​with the clamping base sleeve 1. A drive plate 3-8 is disposed on the upper end face of the clamping sleeve 3-7. The opposite sides of the drive plate 3-8 are fitted onto the drive rod 3-5. A drive cavity 3-9 is disposed on the drive plate 3-8. A swing rod 3-10 is connected to the drive cavity 3-9 by a pin. A drive block 3-11 is connected to the swing rod 3-10. The bottom of the drive block 3-11 is in contact with the clamping sleeve 3-7.

[0041] The supporting counterweight assembly 4 includes a horizontal frame 4-1, which is connected to the inner wall of the supporting frame 2. The horizontal frame 4-1 has an insert groove 4-2 inside, and a counterweight strip 4-3 is installed in the insert groove 4-2.

[0042] In some examples, the force-bearing plate 3-1 is used to drive the rod 3-5 to insert into the insertion hole. After the power line is inserted into the clamping bottom sleeve 1, the swing rod 3-10 swings, and the driving block 3-11 applies downward pressure to the driving plate 3-8. The driving plate 3-8 presses down on the clamping sleeve 3-7, and the clamping sleeve 3-7 presses the upper end of the power line. The clamping plate 3-6 on the driving plate 3-8 slides on the driving rod 3-5, making the up-and-down movement of the driving plate 3-8 and the clamping plate 3-6 smoother.

[0043] If further adjustment of the clamping force is required, the drive rod 3-5 can be rotated by rotating the screw sleeve 3-12 at the top of the drive rod 3-5. Since the screw thread 3-13 at the bottom of the drive rod 3-5 is engaged with the rotating nut 3-14, rotating the drive rod 3-5 will cause the drive rod 3-5 to move up and down in the insertion hole 3-4 of the force plate 3-1, thereby adjusting the position of the clamping plate 3-6 and the clamping sleeve 3-7, so as to achieve the purpose of adjusting the clamping force.

[0044] The transverse frame 4-1 is used to place the mounting slot 4-2. The counterweight strip 4-3 in the mounting slot 4-2 can ensure the stable placement of the clamping bottom sleeve 1. The counterweight strip 4-3 is installed in the mounting slot 4-2 inside the transverse frame 4-1. The number of counterweight strips 4-3 is determined according to actual needs. Multiple counterweight strips 4-3 are placed equidistantly along a straight line in the mounting slot 4-2 to achieve a suitable counterweight effect and improve the stability of the connecting hardware.

[0045] like Figures 1-4 As shown, in this embodiment, a screw sleeve 3-12 is provided at the top of the drive rod 3-5, a screw thread 3-13 is provided at the bottom of the drive rod 3-5, a rotating nut 3-14 is screwed onto the screw thread 3-13, a fixing plate 3-15 is provided at the bottom of the force plate 3-1, and the rotating nut 3-14 is attached to the fixing plate 3-15.

[0046] In some examples, after the rotating nut 3-14 is turned, the rotating nut 3-14 can be turned on the rotating thread 3-13. The rotating nut 3-14 can be limited by the fixed plate 3-15 to make the drive rod 3-5 rise and fall, thereby adjusting the position of the drive plate 3-8.

[0047] For example, such as Figure 1 As shown, there are several counterweight bars 4-3, and multiple counterweight bars 4-3 are equidistantly arranged in the mounting groove 4-2 along a straight line.

[0048] In some examples, multiple counterweights 4-3 can be used to clamp the base sleeve 1 as a counterweight.

[0049] For example, such as Figure 4As shown, the drive block 3-11 has a cam structure. A part of the drive block 3-11 is inserted into the drive cavity 3-9. The drive shaft passes through the drive block 3-11. The drive shaft is fixedly connected to the drive rod 3-5. The drive shaft and the drive block 3-11 are connected by key pin insertion.

[0050] In some examples, the cam-shaped drive block 3-11 can clamp the downward pressure of the clamping sleeve 3-7 during rotation.

[0051] For example, such as Figure 1 As shown, both the clamping bottom sleeve 1 and the clamping sleeve 3-7 are semi-circular structures. The clamping bottom sleeve 1 and the clamping sleeve 3-7 are spliced ​​together to form a circular structure. The inner side wall of the clamping sleeve 3-7 is provided with an anti-slip sleeve 5, which fits against the inner side wall of the clamping sleeve 3-7.

[0052] In some examples, the anti-slip sleeve 5 and the anti-slip pad 3-3 are used for anti-slip clamping of power lines.

[0053] For example, such as Figure 4 As shown, a swing frame 6 is provided at the end of the swing rod 3-10, and a control lever 7 is provided on the swing frame 6. There are two support frames 2, which are respectively placed on opposite sides of the clamping base sleeve 1. There are several drive rods 3-5, which are arranged in two rows on opposite sides of the drive plate 3-8.

[0054] In some examples, the control lever 7 on the swing frame 6 is used to manually adjust the angle of the swing arms 3-10.

[0055] When the power line is inserted into the clamping base sleeve 1, the swing rod 3-10 swings, and the driving block 3-11 applies downward pressure to the driving plate 3-8. By operating the control lever 7, the swing rod 3-10 swings, driving the driving block 3-11 to rotate. Since the driving block 3-11 has a cam structure, the rotation of the driving block 3-11 will push the clamping sleeve 3-7 to move downward, so that the clamping sleeve 3-7 and the clamping base sleeve 1 together clamp the power line. The counterweight strip 4-3 in the mounting groove 4-2 can ensure the stable placement of the clamping base sleeve 1. The counterweight strip 4-3 is installed in the mounting groove 4-2 inside the transverse frame 4-1. The number of counterweight strips 4-3 is determined according to actual needs. Multiple counterweight strips 4-3 are placed equidistantly in the mounting groove 4-2 along a straight line to achieve a suitable counterweight effect and improve the stability of the connecting hardware.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
