Description

Technical Field

[0001] This utility model relates to the field of cable clamp technology, specifically a cable suspension clamp. Background Technology

[0002] Cable suspension clamps are electrical fittings used in overhead transmission lines to suspend transmission conductors on suspension insulator strings or to suspend ground wires on the ground wire supports of towers. They smoothly transfer the vertical load of the cable to the tower and restrain the axial movement of the cable.

[0003] For example, patent CN209516569U discloses an anti-dizziness type center-rotating suspension clamp mechanism, including a hull-shaped suspension clamp body; a pair of symmetrically distributed first side mounting blocks are provided on both sides of the suspension clamp body; the first side mounting blocks are provided with through-hole groove structures; the bottom side of the suspension clamp body is provided with a bottom side protruding plate that cooperates with the first side mounting blocks; a U-shaped rod mounting groove is provided on the inner side of the bottom side protruding plate; a U-shaped fixing rod is installed on the suspension clamp body, passing through the U-shaped rod mounting groove and the first side mounting blocks; and a hull-shaped wire groove is provided inside the suspension clamp body.

[0004] Patent CN218335249U discloses a large-angle double-safety-compression-cover plate suspension clamp, including a suspension clamp body, a suspension clamp body and a suspension clamp cover plate, which cooperate to clamp a wire using two U-shaped screws connected by fasteners, a suspension clamp wedge block is installed on the suspension clamp cover plate, a U-shaped clamp is installed at the U-shaped clamp limiting groove of the suspension clamp body, the cone surface of the suspension clamp cover plate and the cone surface of the wedge block of the suspension clamp are tightly fitted, a large belly-shaped hanging plate is installed in the bolt hole with pin hole on the U-shaped clamp, and a bolt with pin hole and a closed pin are installed in the bolt hole with pin hole on the large belly-shaped hanging plate, forming a large-angle double-safety-compression-cover plate suspension clamp.

[0005] In existing technologies such as those mentioned in the patent, the boat-shaped clamp body of the suspension clamp, the clamping plate that presses the cable onto the boat-shaped clamp body, and the bracket that rotates with the boat-shaped clamp body all need to be assembled at height. First, the bracket must be installed on the suspension insulator string or the tower ground wire support. Then, the boat-shaped clamp body supports the cable through the cable tray, and finally, the two clamping plates are installed onto the boat-shaped clamp body using U-bolts to press the cable into the cable tray. The drawbacks are: first, the boat-shaped clamp body is connected to the bracket while supporting the cable, making operation difficult and inconvenient; second, the boat-shaped clamp body is connected to the bracket from a completely detached state, and the clamping plates and U-bolts are also connected to the boat-shaped clamp body from a completely detached state, posing a risk of the boat-shaped clamp body, clamping plates, U-bolts, U-bolt nuts, and / or swivel bolt pairs falling from height. Utility Model Content

[0006] The purpose of this utility model is to provide a cable suspension clamp to solve the problems of inconvenient installation and easy fall of structural components in the existing cable suspension clamps.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable suspension clamp, comprising a boat-shaped clamp body, at least one clamping plate for pressing the cable onto the boat-shaped clamp body, and a bracket that rotates with the boat-shaped clamp body. A U-shaped bolt is supported across the boat-shaped clamp body, and the boat-shaped clamp body has a receiving groove adapted to the clamping plate. One end of the clamping plate has a through hole, and the other end has a relief groove. The clamping plate is movably fitted onto the first screw of the U-shaped bolt through the through hole. The clamping plate rotates on the first screw... The process includes a limiting station for fitting the groove onto the second screw of the U-bolt, and a clearance station for avoiding the wire groove side of the boat-shaped clamp; the pressing plate located at the limiting station has a pressing station for embedding the receiving groove during its axial sliding stroke on the first screw; a sliding member is slidably connected to the boat-shaped clamp, and the bracket is movably fitted onto the swivel bolt pair on the top of the sliding member; the sliding member has a hanging station located directly above the wire groove and an installation station located on one side of the wire groove during its sliding stroke on the boat-shaped clamp.

[0008] Furthermore, the clamping assembly, which includes U-bolts and clamping plates, is provided in two sets and is distributed on both sides of the sliding member.

[0009] Furthermore, the bottom center of the clamping plate is provided with an arc-shaped wire clamping structure for fitting the cable.

[0010] Furthermore, the top of the side walls on both sides of the boat-shaped clamp is provided with a sliding groove, and the bottom of the sliding member is provided with a slider that slides in cooperation with the sliding groove.

[0011] Furthermore, the sliding component includes two single-unit plates arranged side by side, and the sliders at the bottom of the two single-unit plates are detachably connected to form the slider. Limiting grooves are provided on the inner bottom of both single-unit plates, and a limiting block is fixedly connected to the top of the side wall of the boat-shaped clamp on one side of the groove.

[0012] Furthermore, one of the slider units has a threaded hole at its end along the sliding direction, and the other slider unit has a countersunk hole along the sliding direction. A locking bolt is inserted into the countersunk hole and is threadedly connected to the threaded hole.

[0014] Furthermore, a limiting baffle is movably sleeved on the rotary bolt assembly, and the limiting baffle has a locking position that locks the sliding member in the mounting position during the moving stroke of the rotary bolt assembly.

[0015] Compared with the prior art, the cable suspension clamp provided by this utility model has a clamping plate that is movably sleeved on the first screw of the U-shaped bolt through a through hole, so that the clamping plate has a limiting position, a clearance position, and a wire pressing position. The boat-shaped clamp body is slidably connected to the sliding part of the connecting bracket, so that the sliding part has a hanging position and an installation position. The cable suspension clamp is pre-assembled on the ground, with the clamping plate in the clearance position and the sliding part in the installation position, so that the cable trough is in an open state. After the bracket is installed on the suspension insulator string or the tower ground wire support, the cable can be directly placed into the cable trough, and the cable is initially hung on the cable suspension clamp.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figures 1-10 The present invention provides a cable suspension clamp, including a boat-shaped clamp body 1, two clamping components and a bracket 4. The bracket 4 is rotatably engaged with the boat-shaped clamp body 1, and the boat-shaped clamp body 1 is provided with a groove 11 for accommodating the cable.

[0022] A sliding member 2 is horizontally slidably connected to the boat-shaped clamp 1. Specifically, the top of the side walls on both sides of the boat-shaped clamp 1 are provided with sliding grooves 14, and the bottom of the sliding member 2 is provided with a slider that slides in cooperation with the sliding grooves 14, thereby realizing the sliding cooperation between the boat-shaped clamp 1 and the sliding member 2. During the sliding stroke of the sliding member 2 on the boat-shaped clamp 1, it has a hanging position located directly above the wire groove 11 and an installation position located on one side of the wire groove 11.

[0023] The sliding member 2 includes two side-by-side and connected individual plates 21. When the sliding member 2 is in the installation position, it is located on one side of the cable tray 11, with only one individual plate 21 aligned with one side wall of the boat-shaped clamp 1. When the sliding member 2 is in the mounting position, its center is directly above the cable tray 11, and its two individual plates 21 are aligned with the two side walls of the boat-shaped clamp 1.

[0024] Both individual plate pieces 21 have limiting grooves 22 on their inner bottom sides, and the limiting grooves 22 do not penetrate the outer side of the corresponding individual plate piece 21. A limiting block 15 is fixedly connected to the top of one side wall of the boat-shaped clamp 1, and the limiting block 15 is adapted to both limiting grooves 22. When the sliding member 2 moves to the installation position, the limiting block 15 abuts against the side wall of one of the limiting grooves 22; when the sliding member 2 moves to the mounting position, the limiting block 15 abuts against the side walls of both limiting grooves 22. That is, through the cooperation between the limiting block 15 and the two limiting grooves 22, the sliding member 2 can be limited between the installation position and the mounting position, preventing the sliding member 2 from detaching from the boat-shaped clamp 1.

[0025] The bottom of each of the two individual plates 21 of the sliding member 2 is provided with a slider unit 23. The slider units 23 at the bottom of the two individual plates 21 are detachably connected to form the aforementioned slider. The detachable connection is specifically made as follows: one slider unit 23 has a threaded hole 24 at its end along the sliding direction, and the other slider unit 23 has a countersunk hole 25 along the sliding direction. A locking bolt 26 passes through the countersunk hole 25 and is threadedly connected to the threaded hole 24. This facilitates the installation of the sliding member 2 onto the boat-shaped clamp 1. One slider unit 23 can be installed from the outside to the inside of one side wall of the boat-shaped clamp 1 into the corresponding slide groove 14, and the other slider unit 23 can be installed from the outside to the inside of the other side wall of the boat-shaped clamp 1 into the corresponding slide groove 14. Then, the two slider units 23 are connected together by the locking bolt 26. The limiting block 15 is located between the limiting grooves 22 of the two individual plates 21, and the sliding member 2 can slide within the boat-shaped clamp 1.

[0026] The tops of the two individual plates 21 of the sliding member 2 are jointly equipped with a slewing bolt pair 3. The bracket 4 is U-shaped, and its arc-shaped bottom is fitted onto the slewing bolt pair 3, thereby achieving a slewing connection with the sliding member 2, that is, a slewing connection with the boat-shaped clamp 1. The bracket 4 is located between the two individual plates 21, and its two flush tops are installed on the suspension insulator string or tower ground wire support through connecting bolt pairs 5.

[0027] In addition, a limiting baffle 8 is movably fitted onto the slewing bolt assembly 3. For example, the limiting baffle 8 is radially slidingly connected or circumferentially rotating connected to the slewing bolt assembly 3. The limiting baffle 8 has a locking position during its movement on the slewing bolt assembly 3. When the sliding member 2 is in the mounting position, the limiting baffle 8 moves to its bottom and fits against the outer side of the side wall of the boat-shaped clamp 1 without the limiting block 15, thereby preventing the sliding member 2 from moving to the installation position and locking the sliding member 2 in the mounting position.

[0028] Two clamping assemblies are distributed on both sides of the sliding member 2 along the length of the groove 11. Each clamping assembly includes a U-bolt 6 and a clamping plate 7. The boat-shaped clamp 1 has through holes 12 on both sides of the groove 11. The opening of the U-bolt 6 faces upward, and its two parallel sections are a first screw 61 and a second screw 62. The U-bolt 6 supports the boat-shaped clamp 1 from bottom to top, and the first screw 61 and the second screw 62 each pass through a through hole 12. One end of the clamping plate 7 has a through hole 71, and the other end has a relief groove 72. The clamping plate 7 is movably sleeved on the first screw 61 of the U-bolt 6 through the through hole 71. The clamping plate 7 can rotate and slide circumferentially relative to the first screw 61. During the stroke of the clamping plate 7 rotating on the first screw 61, there is a limiting position for the relief groove 72 to be sleeved on the second screw 62 of the U-bolt 6, and a clearance position to avoid the groove 11.

[0029] The boat-shaped clamp 1 has a receiving groove 13 adapted to the clamping plate 7, which is located above the wire groove 11. When the clamping plate 7 is in the limiting position, it spans directly above the wire groove 11, and at this time, the clamping plate 7 is also directly above the receiving groove 13 and aligned with it. During the axial sliding stroke of the clamping plate 7 in the limiting position on the first screw 61, it has a wire pressing position embedded in the receiving groove 13. An arc-shaped wire pressing structure 73 for fitting the cable is provided in the middle of the bottom of the clamping plate 7. When the clamping plate 7 is in the wire pressing position, the cable is pressed into the wire groove 11 by the arc-shaped wire pressing structure 73, and the clamping plate 7 is limited by the receiving groove 13 so that it cannot rotate relative to the first screw 61. The clamping plate 7 is locked in the limiting position.

[0030] In use, the cable suspension clamp is pre-assembled on the ground. The bracket 4 and the sliding part 2 are connected by a swivel bolt pair 3. The U-bolt 6 spans onto the boat-shaped clamp 1 and a clamping plate 7 is fitted on the first screw 61. Matching nuts are screwed onto the first screw 61 and the second screw 62 respectively (the nuts do not need to be fully tightened, but only need to be located near the top of the first screw 61 and the second screw 62 to prevent the clamping plate 7 from falling off the first screw 61). This makes the sliding part 2 in the installation position and the clamping plate 7 in the clearance position, so that the cable tray 11 is in an open state. After installing the bracket 4 onto the suspension insulator string or tower ground wire bracket via the connecting bolt pair 5, the cable can be placed directly into the cable trough 11. The cable is then initially hung on the cable suspension clamp. At this time, the cable suspension clamp is slightly tilted, but because the depth of the cable trough 11 is sufficient and the holding time is short, the cable will not fall out of the cable trough 11. Then, simply move the sliding member 2 from the installation position to the hanging position and rotate the clamping plate 7 from the clearance position to the limit position and press it down into the receiving groove. Tighten the nuts on the first screw 61 and the second screw 62 of the U-bolt 6 respectively to make the clamping plate 7 press the conductor into the cable trough 11. The installation of the cable suspension clamp and the cable is completed.

[0031] The various structural components of the cable suspension clamp are pre-assembled on the ground and then installed as a whole onto the suspension insulator string or the tower ground wire support. This effectively avoids the risk of falling during the high-altitude assembly process of structural components such as the boat-shaped clamp 1, the clamping plate 7, the U-bolt 6, the matching nuts of the U-bolt 6 and / or the slewing bolt pair 3. Furthermore, the cable is directly placed into the cable tray 11 after the boat-shaped clamp 1 has been pre-connected to the hanger 4, making the operation more convenient.

[0032] The foregoing description of certain exemplary embodiments of this utility model should not be construed as limiting the scope of protection of the claims of this utility model. Those skilled in the art will recognize that the described embodiments can be modified in other ways without departing from the spirit and scope of this utility model.
