Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable fixing devices, in particular to a double jumper suspension clamp. Background Art
[0002] The conductive device that connects the tension wire clamps of the conductors on both sides of the tension corner tower is called an overhead transmission line jumper. The jumper is used to ensure that the live conductor maintains a sufficient electrical distance from the conductive part of the tower. Due to the differences in the operations of the construction personnel, some jumpers are not in a straight line after installation, which will cause discharge and other phenomena. In this case, it is necessary to use a wire clamp to fix the jumper. When two jumpers with similar positions need to be fixed at the same time, two wire clamps need to be used to fix them separately, which increases the difficulty of the work and reduces the work efficiency. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a double jumper wire suspension clamp which can clamp and fix two jumper wires at one time.
[0004] In order to solve the above technical problems, the utility model includes a wire clamp body, and its structural features are: the wire clamp body includes a hanging part located at the upper end that can hang the wire clamp body on the pole tower and a clamping part located at the lower end, the lateral width of the clamping part is greater than the longitudinal width, and two clamping grooves are arranged transversely in the clamping part, the two clamping grooves are arranged in parallel, and the clamping grooves open upward, and two locking blocks that can move up and down are installed on the clamping part, and the lower end of the locking block is provided with a groove corresponding to the clamping groove, and the groove and the clamping groove can form a clamping space for clamping the jumper wire, and the bottom of the locking block is provided with a locking device for fixing the position of the locking block.
[0005] After adopting the above structure, the wire clamp body is hung on the pole tower through the hanging part, and two parallel clamping grooves are provided on the clamping part of the wire clamp body. The jumper wire on the pole tower is inserted into the clamping groove and then the locking block moves downward. After moving downward, the bottom of the locking block is locked by the locking device, and the groove at the lower end of the locking block squeezes the upper end of the jumper wire downward, and the clamping groove receives the lower end of the jumper wire. The jumper wire is fixed by the clamping space formed by the joint extrusion of the clamping groove and the groove, and then the jumper wire is straightened to avoid the shaking of the jumper wire and ensure the fixation of the jumper wire position. At the same time, the two clamping grooves can fix two jumper wires at the same time to avoid contact and entanglement of two adjacent jumper wires, thereby ensuring the transmission quality. At the same time, the two locking blocks clamp the two points of the jumper wire, and the clamping force of the jumper wire is uniform, which avoids damage to the jumper wire caused by greater force at one clamping point.
[0006] A clamping platform is provided between the two clamping grooves, and two through holes are provided on the clamping part that vertically penetrate the clamping part. The two through holes are both located on the clamping platform and the two through holes are arranged on the left and right. The locking device of the locking block includes a bolt that can pass through the through hole, and the top end of the bolt is fixedly connected to the locking block. A spring is sleeved on the lower part of the bolt, and a blocking plate is fixedly connected to the lower part of the bolt. The two ends of the spring are respectively pressed on the blocking plate and the bottom plane of the clamping part. When the lower end face of the locking block presses against the upper surface of the clamping platform, it is the lowest point of the locking block. When the fixing plate moves upward, the spring is compressed, and the bolt can move upward in the through hole. This in turn drives the locking block to move upward, opening the clamping space. At the same time, the locking block can rotate along the axis of the through hole, thereby changing from a front-to-back direction setting to a left-to-right direction setting. After rotation, the upper end of the clamping slot is not blocked by the locking block, making it easier to place the jumper into the clamping slot. After the jumper is placed in the clamping slot, the locking block rotates back to its original position, and the blocking plate is pushed downward by the elastic force of the spring, thereby driving the bolt to move downward, thereby fixing the position of the locking block. By adopting a spring reset method, the stability of the jumper clamping is ensured while facilitating the opening and closing of the clamping space, thereby facilitating the installation and removal of the jumper and improving the installation efficiency.
[0007] The groove is a downwardly open arc-shaped groove, and the inner surface of the groove is an arc-shaped surface, which can better fit the arc surface of the jumper wire to avoid damage to the jumper wire.
[0008] When the locking block clamps the jumper wire, the width in the front-to-back direction is smaller than the distance between the outer end points of the two clamping grooves, and the height of the clamping platform is lower than the height of the highest point of the clamping groove. Therefore, the locking block can extend into the clamping groove after moving downward during clamping. The clamping height of the locking block is determined by the clamping platform, avoiding obstruction of the locking block by the clamping groove, and can better fit the jumper wire and clamp the jumper wire.
[0009] The front and rear end faces of the clamping part are provided with bosses, the left and right width of the bosses is greater than the left and right width of the locking block, the bosses correspond to the position of the locking block, the thickness of the side wall of the clamping groove at the corresponding position of the locking block is increased, the clamping force can be better withstood, and the stability of the clamping of the wire clamp body is increased.
[0010] The hanging part includes a hanging block located at the upper part, and the upper part of the hanging block is provided with a hanging groove extending downward from the top, and the hanging groove is horizontally arranged and passes through the left and right end surfaces of the hanging block. The hanging block is provided with a fixing rod that can pass through the hanging groove and be fixed. By taking out the fixing rod, the hanging groove of the hanging part can be mounted on the pole tower, and then the fixing rod is installed, and then the pole tower suspension is located in the hanging groove, thereby fixing the position of the double jumper wire clamp, which is convenient for the subsequent installation of the jumper.
[0011] In summary, the utility model has the advantages of being able to install two jumpers at one time, ensuring the stability of the jumpers, being convenient for installation and disassembly, and being convenient for clamping and fixing. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 for Figure 1 The structural diagram of the left view;
[0014] Figure 3 It is a schematic diagram of the structure after the locking block moves downward. DETAILED DESCRIPTION
[0015] like Figure 1-3 As shown, the utility model includes a double jumper suspension clamp, which includes a clamp body 1. For the convenience of description, Figure 1 The left and right directions are horizontal, and the front and back directions perpendicular to the paper are longitudinal. The wire clamp body 1 includes a hanging part 2 located on the upper side and a clamping part 3 located in the middle. The clamping part 3 is provided with two inner horizontal clamping grooves 31, and the clamping groove 31 is in a downwardly concave arc shape, and the diameter of the arc matches the diameter of the jumper wire to be clamped. The wire clamp body 1 is equipped with a locking block 4 that can move up and down and cooperate with the clamping part 3 to clamp the jumper wire. The locking block 4 is located above the clamping groove 31, and the lower end of the locking block 4 is also provided with a horizontal groove 41. The groove 41 of the locking block 4 corresponds to the clamping groove 31, and the surface of the groove 41 is an arc surface. The groove 41 and the clamping groove 31 can form a clamping space with a nearly circular cross section. The locking block 4 can move up and down to realize the opening / closing of the clamping space. When the locking block 4 moves to the lowest point, the locking block 4 is fixed by the locking device to realize the stable closure of the clamping space and maintain the clamping of the jumper wire. In this suspension clamp, there are two clamping spaces on the left and right, both of which are arranged horizontally and parallel to each other. The suspension clamp is hung on the tension angle pole tower through the hanging part 2, and then two adjacent jumpers are fixed in the suspension clamp and hung at a high voltage location. By moving the locking block 4 upward, the clamping space is opened, and the two jumpers enter the clamping space respectively. Then the locking block 4 is moved downward, so that the jumper can be clamped and fixed, and the jumper is pulled straight to a regular state, while avoiding contact between adjacent jumpers, avoiding discharge phenomenon at the cage jumper string, and ensuring the power transmission of the jumper.
[0016] like Figure 1-3As shown, in the clamping part 3, the left and right ends of the clamping groove 31 extend outwardly to form arc-shaped surfaces, and the height of the arc-shaped surface gradually decreases from the inside to the outside. When the jumper fits the overall arc-shaped surface, the arc-shaped surface ensures that the pressure on each part of the jumper is equal, avoiding friction of the edges and corners on the jumper, which may damage the jumper. A clamping platform 32 is provided between the two clamping grooves 31, and the clamping part 3 is provided with two through holes vertically arranged and passing through the clamping part 3. The positions of the two through holes correspond to the position of the locking block 4, and the two through holes are arranged on the left and right. The locking block 4 is fixedly connected with a bolt 42 that can pass through the through hole, and the locking device includes a bolt 42 and a spring 43 sleeved on the lower part of the bolt 42. The lower part of the bolt 42 is fixedly connected with a blocking plate 44, and the two ends of the spring 43 are respectively pressed against the blocking plate 44 and the bottom plane of the clamping part 3. When the fixing plate moves upward, the spring 43 is compressed, and the bolt 42 can move upward in the through hole, thereby driving the locking block 4 to move upward and open the clamping space. At the same time, the locking block 4 can rotate along the axis of the through hole, thereby changing from a front-to-back direction setting to a left-to-right direction setting. After rotation, the upper end of the clamping groove 31 is not blocked by the locking block 4, which makes it more convenient to put the jumper into the clamping groove 31. After the jumper is put into the clamping groove 31, the locking block 4 rotates back to its original position, and the elastic force of the spring 43 pushes the blocking plate 44 downward, thereby driving the bolt 42 to move downward, thereby fixing the position of the locking block 4. By adopting the reset method of the spring 43, the stability of the jumper clamping is ensured while facilitating the opening and closing of the clamping space, facilitating the installation and removal of the jumper, and improving the installation efficiency.
[0017] like Figure 1-3 As shown, there is a clamping platform 32 between the two clamping grooves 31, and the upper end surface of the clamping platform 32 is a plane. After the locking block 4 moves downward, the lower end surface of the locking block 4 fits with the upper end surface of the clamping plane, thereby determining the position of the locking block 4. In this embodiment, the height of the clamping platform 32 is lower than the height of the highest point of the clamping groove 31. At the same time, when the locking block 4 is arranged in the front-to-back direction, the distance in the front-to-back direction is less than the distance between the upper ends of the outer ends of the two clamping grooves 31. It is smaller than the distance between the upper end point of the front end surface of the front clamping groove 31 and the upper end point of the rear end surface of the rear clamping groove 31. Then, the locking block 4 can extend into the clamping groove 31 after moving downward during clamping, and the clamping height of the locking block 4 is determined by the clamping platform 32, avoiding the blocking of the locking block 4 by the clamping groove 31, and can better fit the jumper and clamp the jumper.
[0018] like Figure 1-3 As shown, in the present embodiment, the front and rear end faces of the clamping portion 3 are provided with bosses 33, the left-right width of the bosses 33 is greater than the left-right width of the locking block 4, the bosses 33 correspond to the locking block 4 in position, the thickness of the side wall of the clamping groove 31 at the corresponding position of the locking block 4 is increased, the clamping force can be better withstood, and the clamping stability of the wire clamp body 1 is increased.
[0019] like Figure 1-3As shown, the hanging part 2 includes a hanging block 21 located at the upper part, and the upper part of the hanging block 21 is provided with a hanging groove 22 extending downward from the top, and the hanging groove 22 is arranged horizontally and passes through the left and right end surfaces of the hanging block 21. The hanging block 21 is provided with a fixing rod 23 that can pass through the hanging groove 22 for fixing, and the hanging wire clamp is placed on the high-voltage tower. Then the position of the jumper and the distance between adjacent jumpers are fixed. By taking out the fixing rod 23, the hanging groove 22 of the hanging part 2 can be put on the pole tower, and then the fixing rod 23 is installed, and then the pole tower suspension is located in the hanging groove 22, and then the position of the double jumper wire clamp is fixed, which is convenient for the subsequent installation of the jumper.
