Description

Technical Field

[0001] This invention relates to the field of tension clamp technology, and more specifically, to a wedge-shaped insulated tension clamp designed to prevent wire derailment. Background Technology

[0002] With the sustained and rapid development of my country's economy and society and the significant improvement in the living standards of urban and rural residents, higher requirements have been placed on the reliability and stability of power supply. In order to adapt to the continuous increase in urban and rural green coverage and effectively cope with the impact of severe weather such as typhoons and heavy rains on power distribution lines, insulated overhead wires have been widely used in power distribution networks. These wires can not only effectively reduce power outage accidents caused by tree contact, wind and rain, etc., but also significantly improve the power supply reliability of the power grid. Against this background, insulated tension clamps, as key hardware in insulated overhead wire lines, directly affect construction efficiency and operational safety in terms of their ease of installation and reliability.

[0003] However, in existing installation practices for insulated clamps, a wedge-shaped housing is typically pre-assembled, and the clamp is then inserted into a pre-designed mounting hole on the housing surface. Because the diameter of this mounting hole closely matches the outer diameter of the clamp, significant frictional resistance arises during assembly, making it difficult for the clamp to be smoothly inserted. Construction workers often need to use additional force to complete the installation, increasing labor intensity, reducing work efficiency, and consequently affecting the overall construction progress and economic efficiency. Therefore, optimizing the assembly process of the insulated clamp and wedge-shaped housing while ensuring installation quality and reducing installation difficulty has become an urgent technical problem to be solved in power distribution network construction.

Detailed Implementation

[0031] 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. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0033] The present invention relates to an anti-derailment wedge-shaped insulating tension clamp comprising a first wedge-shaped outer shell 1, a sliding groove 11, a fitting hole 12, a third connecting hole 13, a second wedge-shaped outer shell 2, a connecting plate 3, a first connecting hole 31, a second connecting hole 32, a first nut 33, a bolt 4, a second nut 41, an installation mechanism 5, a force-bearing telescopic rod 51, a contact ring 52, an expansion rod 53, a slider 54, a push plate 55, a clamping ring 56, an extension rod 57, a self-locking mechanism 6, a self-locking assembly 60, a support assembly 600, a support frame 601, a return spring 602, a limiting post 603, a driven plate 604, a return telescopic rod 605, a limiting hole 606, a self-locking plate 61, a pressing plate 62, a self-locking hole 63, a limiting mechanism 7, an insulating clamp 71, a support extension rod 72, a limiting plate 73, a threaded rod 74, a turntable 75, a slot 76, a threaded hole 77, a cable hole 78, and a clamp groove 79.

[0034] like Figure 1-2As shown, two connecting plates 3 are respectively hinged to one end of the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2. The two connecting plates 3 are hinged together by bolts 4. Two mounting mechanisms 5 are respectively set inside the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2. The self-locking assembly 60 is fixedly set on the first wedge-shaped outer shell 1, and the self-locking plate 61 is fixedly set on the second wedge-shaped outer shell 2. There are two sets of self-locking assembly 60 and self-locking plate 61, which are respectively set on both sides of the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2. The limiting mechanism 7 is movably set in the groove of the combination of the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2.

[0035] The first connecting hole 31 is provided at one end of the connecting plate 3 that connects the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2. The second connecting hole 32 is provided at one end of the connecting plate 3 that connects the bolt 4. The two third connecting holes 13 are respectively provided at the ends of the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2. The connecting plate 3 is hinged to the first connecting hole 31 and the third connecting hole 13 by the first nut 33. The two second nuts 42 are respectively hinged to both ends of the bolt 4.

[0036] Two sliding grooves 11 are respectively disposed inside the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2. Two mounting mechanisms 5 are respectively disposed inside the two sliding grooves 11. Half of the fitting hole 12 is disposed on the first wedge-shaped outer shell 1 and the other half is disposed on the second wedge-shaped outer shell 2. There are two sets of fitting holes 12.

[0037] like Figure 3-4As shown, one end of the force-bearing telescopic rod 51 is fixedly set at the center of the slide groove 11, and the contact ring 52 is fixedly set at the other end of the force-bearing telescopic rod 51. Two expansion rods 53 are respectively hinged to both sides of the contact ring 52. Two sliders 54 are respectively hinged to the ends of the two expansion rods 53 away from the contact ring 52. Two push plates 55 are respectively hinged to the ends of the two sliders 54 away from the expansion rods 53. Two clamping rings 56 are respectively hinged to the ends of the two push plates 55 away from the sliders 54. One end of the two extension rods 57 is fixed to the bottom of the two clamping rings 56, and the other end is fixed in the slide groove 11. During the movement of the contact ring 52, it will contact the surface of the insulating clamp 71. After the contact ring 52 contacts the insulating clamp 71 and remains stationary, the force-bearing telescopic rod 51 will continue to retract in the direction of mutual approach. At the same time, the end of the expansion rod 53 and the contact ring 52 remain stationary, while the other end of the expansion rod 53 will change the thrust angle of the slider 54, pushing the slider 54 to slide in the direction of mutual distance on the inner wall of the groove 11. When the slider 54 slides, it will push the push plate 55 to move in the direction of mutual approach, effectively... By setting the clamping ring 56 to fit into the slot 76, the insulated wire clamp 71 can be installed quickly, improving installation efficiency and saving pulling force. The operator can pick up the first wedge-shaped shell 1 and the second wedge-shaped shell 2 and move them toward each other. While the first wedge-shaped shell 1 and the second wedge-shaped shell 2 are moving, the force-bearing telescopic rod 51 and the contact ring 52 will move toward each other. At the same time, the expansion rod 53, the slider 54, the push plate 55, the clamping ring 56, and the extension rod 57 move toward each other.

[0038] like Figure 5-6As shown, two support components 600 are fixedly connected by a push plate 62. Each support component 600 includes a support frame 601 whose bottom surface is fixedly mounted on a first wedge-shaped outer shell 1, two limiting holes 606 respectively located on both sides of the support frame 601, two limiting posts 603 movably mounted on the support frame 601 through the two limiting holes 606, one end of each limiting post 603 being fixedly mounted on two return springs 602, two driven plates 604 being fixedly mounted on the ends of the two return springs 602 away from the limiting posts 603, one end of a reset telescopic rod 605 being fixedly mounted on the top surface of the support frame 601, the ends of the two driven plates 604 away from the return springs 602 being hinged to the top sides of the reset telescopic rod 605, the top of the reset telescopic rod 605 being fixedly connected to the push plate 62, and a self-locking hole 63 being located on a self-locking plate 61, which is adapted to the limiting post 603. As the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2 move toward each other, the support frame 601 and the self-locking plate 61 also move toward each other. At this time, the limiting post 603, the return spring 602, the driven plate 604, the push plate 62, and the return telescopic rod 605 also move with the support frame 601. When the limiting post 603 is squeezed, it will move toward the direction away from each other. When the limiting post 603 moves, it will squeeze the return spring 602, causing the return spring 602 to contract toward the direction away from each other. At the same time as the limiting post 603 moves, it will push the end of the driven plate 604 to move toward the direction away from each other. When the self-locking hole 63 on the surface of the self-locking plate 61 moves to the same position as the limiting post 603, there is no squeezing force. The limiting post 603 will move toward the direction of mutual approach through the elastic force of the return spring 602 and move into the interior of the self-locking hole 63, thereby completing the self-locking.

[0039] When it is necessary to disassemble the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2, simply press down on the push plate 62. At this time, the reset telescopic rod 605 retracts downward. When the reset telescopic rod 605 retracts downward, it will drive the end of the driven plate 604 to move downward, while the other end of the driven plate 604 will move away from each other. When the driven plate 604 moves, it will pull the limiting post 603 to move closer to each other. At this time, the limiting post 603 will separate from the self-locking hole 63, thereby completing the disassembly. The setting of the limiting post 603 and the self-locking plate 61 effectively achieves the function of quick installation and quick disassembly, and replaces the cumbersome steps of screw installation, improving the efficiency of installation and disassembly.

[0040] like Figure 7-8As shown, the insulating clamp 71 has cable holes 78 at both ends, and two parallel slots 76 on its surface. The slots 76 are adapted to the clamping ring 56. Two threaded holes 77 are symmetrically arranged in the middle of the insulating clamp 71. Two threaded rods 74 are hinged in the two threaded holes 77. Two turntables 75 are fixedly arranged at the ends of the two threaded rods 74 away from the insulating clamp 71. The turntables 75 are adapted to the fitting holes 12. Two limiting plates 73 are fixedly arranged at the ends of the two threaded rods 74 away from the turntables 75. Two clamp grooves 79 are arranged in the insulating clamp 71. One end of the two supporting extension rods 72 is fixedly arranged in the two clamp grooves 79, and the other end is fixedly arranged on the limiting plates 73. After the insulated clamp 71 is installed, the cable can be passed through the cable hole 78, and then the turntable 75 is rotated. When the turntable 75 rotates, it will drive the threaded rod 74 to rotate. When the threaded rod 74 rotates, it will move towards each other. When the threaded rod 74 moves, it will push the limiting plate 73 to move towards each other. When the limiting plate 73 moves, it will pull the support extension rod 72 to extend towards each other. During the movement of the limiting plate 73, it will contact the surface of the cable and limit the cable. The limiting plate 73 can effectively limit and fix the cable, and can also fix cables of different diameters.

[0041] In use, the operator can lift the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2 and move them closer together. Simultaneously, the movement of the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2 will cause the force-bearing telescopic rod 51 and the contact ring 52 to move closer together. At the same time, the expansion rod 53, slider 54, push plate 55, clamping ring 56, and extension rod 57 also move closer together. During the movement of the contact ring 52, it will contact the surface of the insulating clamp 71. After the contact ring 52 contacts the insulating clamp 71, it remains stationary. At this time, the force-bearing telescopic rod 51 will continue to retract closer together, while the end of the expansion rod 53 and the contact ring 52 remain stationary. The other end of the expansion rod 53 will change its thrust angle through the slider 54. The slider 54 is pushed to slide away from each other on the inner wall of the groove 11. When the slider 54 slides, it pushes the push plate 55 to move closer to each other. When the push plate 55 moves, it pushes the clamping ring 56 to move closer to each other and fits against the inner wall of the slot 76. When the clamping ring 56 moves, it pulls the extension rod 57 to extend closer to each other. When the first wedge shell 1 and the second wedge shell 2 move closer to each other, the support frame 601 and the self-locking plate 61 move closer to each other at the same time. At this time, the limiting post 603, the return spring 602, the driven plate 604, the push plate 62, and the return telescopic rod 605 will also move with the support frame 601. During the movement of the self-locking plate 61, it will interact with the surface of the limiting post 603. The contact surfaces press against the limiting post 603, causing it to move away from the limiting post 603. This movement compresses the return spring 602, causing it to contract. Simultaneously, the movement of the limiting post 603 pushes the end of the driven plate 604 away from the limiting post, while the other end of the driven plate 604 pulls the return telescopic rod 605 downwards. The contraction of the return telescopic rod 605 causes the pressing plate 62 to move downwards. When the self-locking hole 63 on the surface of the self-locking plate 61 reaches the same position as the limiting post 603, the pressing force is released. The limiting post 603, through the elastic force of the return spring 602, moves towards the limiting post 603 and reaches the self-locking position. The self-locking mechanism is achieved by inserting the locking pin into the hole 63. When disassembling the first wedge-shaped outer shell 1 and the second wedge-shaped outer shell 2, simply press down on the push plate 62. The reset telescopic rod 605 retracts downwards, causing the end of the driven plate 604 to move downwards. The other end of the driven plate 604 moves away from each other, pulling the limiting post 603 towards each other. The limiting post 603 then separates from the self-locking hole 63, completing the disassembly. After the insulated wire clamp 71 is installed, the cable can be passed through the cable hole 78. Then, the turntable 75 is rotated. Rotating the turntable 75 causes the threaded rod 74 to rotate, and the threaded rod 74 moves towards each other.When the threaded rod 74 moves, it pushes the limiting plate 73 to move closer together. When the limiting plate 73 moves, it pulls the support extension rod 72 to extend closer together. During the movement of the limiting plate 73, it comes into contact with the surface of the cable and limits its movement.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
