Description

Technical Field

[0001] This utility model relates to the field of triple tension string technology, specifically a disc suspension insulator triple tension string. Background Technology

[0002] An insulator string is an assembly of two or more insulator elements combined together to flexibly suspend a conductor. Insulator strings are protective devices with fixing and operational requirements, used to suspend conductors and insulate them from towers and the ground.

[0003] A search revealed an existing patent (publication number: CN215183310U) that discloses a disc-type suspension insulator triple tension string, including hanging point hardware. A U-shaped hanging ring assembly is fixedly connected to the hanging point hardware, and an adjusting disc is fixedly connected to the U-shaped hanging ring assembly. The positioning mechanism includes a housing fixedly mounted on the connecting mechanism. The housing has an internal cavity, and a rotating shaft is movably positioned at the center of the cavity. A roller is fixedly mounted on the outer side of the rotating shaft, and several sets of through holes are formed inside the roller. A positioning hole is formed inside the rotating shaft. A positioning rod is connected through the housing and engages with the positioning hole. Connecting ropes are fixedly connected to both sides of the adjusting disc, and the connecting ropes pass through the through holes. This invention facilitates stable fixing of the adjusting disc and allows for selective positioning based on distance.

[0004] It prevents the existing adjustment disc from shaking or moving during use, but it has a drawback: when adjusting the adjustment disc, it is necessary to remove the bolts and nuts, insert the bolts into different holes, and then tighten the nuts to adjust the distance, which is a rather cumbersome adjustment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a disc-shaped suspension insulator triple tension string, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-section tension string of disc-shaped suspension insulators, comprising three adjusting discs, a hanging plate mounted above the adjusting discs, a disc-shaped suspension insulator mounted above the hanging plate, a three-transformer two-section plate mounted on top of the disc-shaped suspension insulator, a connecting plate mounted on top of the three-transformer two-section plate, an adjusting disc comprising a housing, a fixing block fixed inside the housing, and an equalizing ring provided on the outer side of the disc-shaped suspension insulator, the top of the equalizing ring being fixedly connected to the three-transformer two-section plate;

[0007] A worm gear is rotatably connected to the outer wall of the fixed block. A through hole is provided on the front surface of the worm gear. An arc-shaped groove is provided on the front surface of the housing. An installation hole is provided above the front surface of the housing. A worm is rotatably connected inside the housing. The worm and the worm gear are meshed together. A hanging point hardware is installed below the adjusting plate.

[0008] Preferably, a hexagonal block is fixed to the bottom of the worm gear.

[0009] Preferably, a ring is fixed inside the housing on the outside of the worm gear. Two fixing holes are opened on the outer wall of the worm gear. A fixing plate is fixed inside the fixing holes. A moving rod is slidably connected inside the fixing plate. A top block and a moving block are fixed at both ends of the moving rod, respectively. A return spring is sleeved on the outer wall of the moving rod between the top block and the fixing plate.

[0010] Preferably, the end of the moving block away from the moving rod and the inner wall of the ring are both frosted surfaces. The bottom of the worm gear has a circular hole, and a compression spring is fixed inside the circular hole. The other end of the compression spring is fixed to a circular rod, and an annular groove is formed on the outer wall of the circular rod.

[0011] Preferably, the elastic force of the compression spring is greater than the elastic force of the two return springs.

[0012] Preferably, the hexagonal block has three pressure rods slidably connected inside. Beneficial effects

[0013] This utility model provides a disc-shaped suspension insulator triple tension string. Compared with the prior art, it has the following advantages:

[0014] 1. This disc-shaped suspension insulator triple tension string, by setting an adjustment disc, allows a hexagonal wrench to rotate a hexagonal block, which in turn rotates a worm gear, which in turn rotates a worm wheel, which moves a bolt inserted into a hole. This allows adjustment of the distance between the hanging point hardware and the hanging plate. This is simple and convenient, without the need to loosen the bolts and nuts, insert the bolts into different holes, and then tighten the nuts to adjust the distance.

[0015] 2. This disc-shaped suspension insulator triple tension string is equipped with a moving block, a circular ring, a moving rod, a top block, a circular rod, and a compression spring. The compression spring pushes the circular rod, the circular rod presses against the top block, and the top block moves the moving rod and the moving block. The moving block and the circular ring come into contact, and the frosted surface of the contact increases the friction, which can limit the rotation of the moving block and the worm gear and prevent the worm gear from reversing.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution: a three-section tension string of disc-shaped suspension insulators, including three adjusting discs 1. A hanging plate 2 is installed above the adjusting disc 1, and a disc-shaped suspension insulator 3 is installed above the hanging plate 2. A three-section two-section connecting plate 5 is installed on the top of the disc-shaped suspension insulator 3, and a connecting plate 7 is installed on the top of the three-section two-section connecting plate 5. The adjusting disc 1 includes a housing 102, and a fixing block 105 is fixed inside the housing 102. An equalizing ring 4 is provided on the outer side of the disc-shaped suspension insulator 3, and the top of the equalizing ring 4 is fixedly connected to the three-section two-section connecting plate 5. The outer side of the fixing block 105... A worm gear 103 is rotatably connected to the side wall. A through hole 107 is opened on the front surface of the worm gear 103. An arc groove 104 is opened on the front surface of the housing 102. An installation hole 120 is opened above the front surface of the housing 102. A worm 106 is rotatably connected inside the housing 102. The worm 106 and the worm gear 103 are meshed together. A hanging point hardware 6 is installed below the adjusting plate 1, so that the distance between the hanging point hardware 6 and the hanging plate 2 can be adjusted. This is simple and convenient. A hexagonal block 101 is fixed at the bottom of the worm 106, which makes it easy to rotate the worm 106.

[0024] Furthermore, a ring 108 is fixed inside the housing 102 outside the worm gear 106. Two fixing holes 119 are formed on the outer wall of the worm gear 106. A fixing plate 116 is fixed inside the fixing holes 119. A moving rod 115 is slidably connected inside the fixing plate 116. A top block 118 and a moving block 114 are fixed at both ends of the moving rod 115, respectively. A return spring 117 is sleeved on the outer wall of the moving rod 115 between the top block 118 and the fixing plate 116. The end of the moving block 114 away from the moving rod 115 and the inner wall of the ring 108 are both ground. The bottom of the worm gear 106 has a circular hole 113. A compression spring 112 is fixed inside the circular hole 113. A circular rod 110 is fixed to the other end of the compression spring 112. An annular groove 111 is formed on the outer wall of the circular rod 110. This can limit the rotation of the moving block 114 and the worm gear 106 and prevent the worm wheel 103 from reversing. The elastic force of the compression spring 112 is greater than the elastic force of the two return springs 117. In this way, the circular rod 110 can press the top block 118 to move. Three pressure rods 109 are slidably connected inside the hexagonal block 101, which can make the circular rod 110 move.

[0025] During operation, the hanging point hardware 6 and the adjusting plate 1 are installed by bolts passing through the arc groove 104 and the through hole 107. The hanging plate 2 and the adjusting plate 1 are installed by bolts passing through the mounting hole 120. When the distance needs to be adjusted, the nut connected to the adjusting plate 1 is loosened, so that the hexagonal wrench is placed on the hexagonal block 101. The hexagonal wrench presses the pressure rod 109, and the pressure rod 109 presses the round rod 110. The round rod 110 moves upward, so that the annular groove 111 aligns with the fixing hole 119. The return spring 117 pushes the top block 118, the moving rod 115, and the moving block 114 to move. The moving block 114 separates from the annular ring 108. Then the wrench is turned, and the wrench carries... Hexagonal block 101 rotates, causing worm gear 106 to rotate. Worm gear 106 rotates, causing worm wheel 103 to rotate. Worm wheel 103 moves the bolt inserted into through hole 107, thus adjusting the distance between hanging point hardware 6 and hanging plate 2. After adjustment, the wrench is removed, and compressed spring 112 pushes round rod 110 to move. Round rod 110 presses top block 118, and top block 118 moves moving rod 115 and moving block 114. Moving block 114 contacts ring 108, with the frosted surfaces in contact, increasing friction and limiting the rotation of moving block 114 and worm gear 106, preventing worm wheel 103 from reversing. It is simple and convenient.
