Description

Technical Field

[0001] The utility model relates to the technical field of insulated wire installation, in particular to an overhead insulated wire installation support device. Background Art

[0002] A layer of non-conductive material, such as resin, plastic, silicone rubber, PVC, etc., is evenly and sealed around the outside of the wire to form an insulating layer to prevent the conductor from contacting the outside world and causing accidents such as leakage, short circuit, electric shock, etc. The wire is called an insulated wire. When using such an insulated wire, in order to prevent it from being laid on the ground for a long time and causing friction with the ground to cause surface wear, it is usually suspended for use. When erecting the wire, this type of support device plays a very important role.

[0003] In response to this, Chinese patent number CN210074723U proposes a support device for overhead insulated conductors, which is convenient for limiting and fixing conductors with different outer diameters, has strong practicality, and is provided with a rotation and threaded limit mechanism. The spacing between the first arc-shaped conductor clamp and the second arc-shaped conductor clamp can be adjusted by turning a hand wheel, which is convenient for installation. However, when using this type of insulated conductor support device, the intensity of electromagnetic induction generated at the upper end of the insulated conductors carrying different currents is different, and it is necessary to adjust the position of the insulated conductors at the upper end of the same support device to reduce the electromagnetic influence between them. The support distance of ordinary support devices cannot be adjusted, and an external connection structure is required to lengthen the distance, which is cumbersome to operate and increases the installation cost, thereby reducing the practicality of the device.

[0007] In one example, screw holes are provided at the edges of both sides of the two movable brackets, connecting frames are inserted through the inner walls of the four connecting grooves, and two clamping blocks are fixed between the four connecting frames.

[0008] In one example, the outer walls of one end of the two clamping blocks are respectively interlaced and connected with the inner walls of the two limiting grooves, and the inner walls of the four screw holes are interlaced with bolts.

[0009] In one example, a slot is formed on the inner wall of the support frame, and the outer walls of the two movable brackets are respectively connected to the inner walls at both ends of the slot, and the outer walls of the four limit bars are respectively connected to the inner walls of the slot in a sliding manner.

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the overall concept of the utility model, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0022] The examples are as follows:

[0023] The utility model provides Figure 1-4 An overhead insulated conductor erection support device shown includes a support frame 1, and a fixing mechanism for conveniently adjusting the support width is provided at the upper end of the support frame 1;

[0024] The fixing mechanism for conveniently adjusting the support width includes movable brackets 2 inserted at both ends of the support frame 1, limit bars 3 are fixedly provided on both sides of the outer walls of the two movable brackets 2, racks 4 are fixedly provided on one end of one side of the two movable brackets 2, a gear 5 is rotatably provided in the middle position of the inner wall of the support frame 1, and the gear 5 is respectively meshed with the two racks 4, a rotating shaft 6 is fixedly provided in the middle position of one side of the gear 5, and the other ends of the two movable brackets 2 are provided with limit grooves 7, and connecting grooves 8 are provided at the outer edges of the two limit grooves 7 at both ends of the two movable brackets 2. The gear 5 is rotatably installed in the middle position of the card slot 12, and a limit structure is provided at the end of the two racks 4, so that when it is meshed with the gear 5 to the end, it cannot continue to mesh and transmit, so that the movable bracket 2 will not separate from the support frame 1.

[0025] Screw holes 9 are provided at the edges of both sides of the two movable brackets 2, and connecting frames 10 are inserted through the inner walls of the four connecting grooves 8, and two clamping blocks 11 are fixed between the four connecting frames 10;

[0026] Furthermore, the outer walls of one end of the two clamping blocks 11 are respectively connected with the inner walls of the two limiting grooves 7, and the inner walls of the four screw holes 9 are all provided with bolts, which are threadedly connected with the screw holes 9, and the bolts pass through the screw holes 9 and contact the corresponding connecting frame 10, and tightening the bolts can fix the position of the clamping block 11 by fixing the connecting frame 10;

[0027] Furthermore, a slot 12 is formed on the inner wall of the support frame 1 , and the outer walls of the two movable brackets 2 are respectively connected to the inner walls at both ends of the slot 12 , and the outer walls of the four limit bars 3 are respectively connected to the inner walls of the slot 12 in a sliding manner.

[0028] One side of the outer wall of the support frame 1 is provided with two slide grooves 13, and a limit bracket 14 is slidably provided between the two slide grooves 13, and a buckle 15 is inserted into one side of the limit bracket 14. One side of the inner wall of the two slide grooves 13 is fixed with a spring 16, and one end of the two springs 16 is respectively fixedly connected to the two sides of the bottom of the limit bracket 14. After the buckle 15 is inserted into the connecting hole 17, the inner wall of one end of the buckle 15 is sleeved on the outer wall of one end of the rotating shaft 6, and the outer wall of one end of the rotating shaft 6 is in a cross shape. When the buckle 15 is engaged with its outer wall, it just limits it, so that the rotating shaft 6 cannot rotate, and then the gear 5 and the rack 4 cannot mesh and transmit;

[0029] Furthermore, a connecting hole 17 is opened in the middle position of one side of the support frame 1, and one end of the rotating shaft 6 is connected with the inner wall of the connecting hole 17 through an insertion, and the outer wall of one end of the buckle 15 is connected with the inner wall of the connecting hole 17 through an insertion, and a rubber pad 18 is fixed on one side of the inner wall of the two limiting grooves 7. A rubber pad 18 is arranged on one side of the inner wall of the limiting groove 7, which cooperates with the clamping block 11 to squeeze the insulated wire to prevent the outer sheath of the wire from being easily worn.

[0030] Working principle: When using the overhead insulated wire erection support device in this design, first, the mobile bracket 2 at the upper end of the device needs to be installed in the card slots 12 at both ends of the support frame 1, and the limit bars 3 on both sides of the mobile bracket 2 are limited by the card slots 12. When supporting the insulated wire, slide the connecting frame 10 in the connecting slot 8 and then move the card block 11 to clamp the wire in the limit slot 7, and use bolts to pass through the screw holes 9 to fix the position of the connecting frame 10, and then fix the position of the card block 11 to clamp the wire therein. According to the intensity of the current carrying, use an external sleeve to clamp in the connecting hole 17 to rotate the shaft 6 so that the gear 5 rotates in the support frame 1, and then the meshing rack 4 moves, so that the two mobile brackets 2 move forward. The clamp 15 can be moved in opposite directions to adjust the distance between the two end wires, thereby reducing the influence of the magnetic field on them. At the same time, no external extension equipment is required, thereby improving the practicality of the device. When adjusting the distance, the buckle 15 is pulled out from the connecting hole 17, and under the elastic action of the spring 16, it slides up in the slide groove 13 together with the limiting bracket 14, without hindering the insertion of the sleeve and the connecting hole 17. After adjusting the distance, the sleeve is pulled out, and then the limiting bracket 14 is pulled to make the compression spring 16 slide in the slide groove 13 until the buckle 15 can be inserted into the connecting hole 17 and the rotating shaft 6 therein is stuck, so that it cannot rotate by itself, and the mobile bracket 2 is locked. The distance cannot be adjusted by itself without human operation, thereby improving the protection of the device.
