Description

Technical Field

[0001] This utility model relates to the field of line fixing technology, specifically to a wire fixing device for power transmission and transformation lines. Background Art

[0002] A wire fixture is a special fixture used to fix wires after they are laid and installed, so that they occupy the correct position and prevent them from moving due to external force or their own weight. The wire fixture fixes the wires to ensure that the laid wires are arranged neatly without cross-arrangement, and can also prevent the generation of eddy current losses.

[0003] Chinese Patent Publication No. CN219535442U discloses a wire fixing device for power transmission and transformation lines, including a mounting ring fixedly connected to a base plate, and a control mechanism disposed on a first threaded rod for controlling the fixing force of a second fixing plate on the wire. The control mechanism includes a mounting plate fixedly connected to the end of the first threaded rod away from the mounting ring, a rotating tube rotatably connected to the other side of the mounting plate, a control plate slidably connected to the rotating tube, and multiple T-shaped rods slidably connected to the control plate. Each T-shaped rod has a control block fixedly connected to its end near the mounting plate. This invention, through the setting of the control mechanism and the adjustment action of the adjustment mechanism, ensures both the firmness of the wire clamping and avoids damage to the outer insulation of the wire due to excessive fixing force, thereby further guaranteeing the service life and safety of the wire.

[0004] However, the wire fixing device for power transmission and transformation lines is too rigid in fixing the wires, lacking effective protection for the outer surface. At the same time, the adjustment mechanism also lacks the necessary buffering performance, making the wires easy to be damaged during the fixing process. In addition, the device fails to provide a sorting function when fixing the wires, and the wires are often piled up and squeezed together, which is not conducive to sorting and organizing, and also increases the risk of wire damage. Summary of the Invention

[0005] To address the aforementioned problems, a power transmission line wire fixing device is provided. When wires need to be placed, they can enter the device through the gap between the first and second fixing plates and be categorized by multiple load-bearing plates. This facilitates timely removal and replacement of damaged wires in the event of a line fault. When wires need to be fixed, rotating the adjusting screw drives the lifting plate to move up and down. The lifting plate then drives the first and second pressure plates to perform a pressing action. The second pressure plate has a buffering function, and when it comes into contact with the wires on the load-bearing plates, it can effectively position the wires.

[0006] To address the problems in the existing technology, this utility model provides a wire fixing device for power transmission and transformation lines, including a first fixing plate, a second fixing plate, an adjusting screw, a lifting plate, a first pressure plate, a second pressure plate, and a load-bearing plate. The second fixing plate is disposed on one side of the first fixing plate. The adjusting screw is evenly spaced on the top of the first and second fixing plates. The lifting plate is disposed at one end of the adjusting screw. The lifting plate and the adjusting screw are connected by a working bearing. The first pressure plate is disposed below the lifting plate, the second pressure plate is disposed below the first pressure plate, and the load-bearing plate is disposed below the second pressure plate.

[0007] Preferably, guide plates are fixedly connected to the upper inner walls of both the first and second fixed plates, and a limiting groove matching the lifting plate is provided on the outer side of the guide plate. A first mounting plate is provided at the top center of the first pressure plate.

[0008] Preferably, a first hollow plate matching the first mounting plate is provided at the bottom center of the lifting plate, and the first mounting plate and the first hollow plate are connected by a first bolt.

[0009] Preferably, the top of the first pressure plate has a circular hole, and a threaded rod perpendicular to the second pressure plate passes through the inside of the circular hole. A return spring is sleeved on the outside of the threaded rod, and a threaded cap for adjusting the elasticity is threaded onto one end of the threaded rod.

[0010] Preferably, rubber pads are adhered to the surfaces of the second pressure plate and the load-bearing plate that are close to each other.

[0011] Preferably, a second hollow plate is provided on the inner wall of the first hollow plate and below the guide plate, and a second mounting plate connected to the load-bearing plate is provided inside the second hollow plate. The second mounting plate and the load-bearing plate are connected by a second bolt.

[0012] Preferably, a third hollow plate is symmetrically arranged on one side of the second fixing plate, and an insert plate connected to the first fixing plate is slidably installed inside the third hollow plate. The third hollow plate and the insert plate are connected by auxiliary bolts.

[0013] Preferably, a working plate is provided on one side of the third hollow plate, a supporting threaded post is passed through the interior of the working plate, a nut for limiting the position is provided at one end of the supporting threaded post, and a fixing seat is provided at the bottom of the supporting threaded post.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The distance between the first and second fixing plates is adjustable, allowing for easy adjustment of the wire's fixing position according to the wire's needs. When a wire needs to be placed, it can enter the device through the gap between the first and second fixing plates and be categorized by multiple load-bearing plates, facilitating timely troubleshooting and replacement of damaged wires in case of line faults. When a wire needs to be fixed, rotating the adjusting screw drives the lifting plate to move up and down, which in turn drives the first and second pressure plates to perform a pressing action. The second pressure plate has a buffering function, and when it comes into contact with the wire on the load-bearing plate, it can effectively position the wire. Attached Figure Description

[0023] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Please refer to Figures 1 to 6A power transmission line wire fixing device includes a first fixing plate 1, a second fixing plate 2, an adjusting screw 3, a lifting plate 4, a first pressure plate 5, a second pressure plate 6, and a load-bearing plate 7. The second fixing plate 2 is disposed on one side of the first fixing plate 1. The adjusting screw 3 is evenly spaced on the top of the first fixing plate 1 and the second fixing plate 2. The lifting plate 4 is disposed at one end of the adjusting screw 3. The lifting plate 4 and the adjusting screw 3 are connected by a working bearing. The first pressure plate 5 is disposed below the lifting plate 4. The second pressure plate 6 is disposed below the first pressure plate 5. The load-bearing plate 7 is disposed below the second pressure plate 6.

[0025] The distance between the first fixing plate 1 and the second fixing plate 2 is adjustable, which facilitates adjusting the fixing position of the wire according to the needs of the wire. When the wire needs to be placed, the wire can enter the device through the gap between the first fixing plate 1 and the second fixing plate 2, and be classified by multiple load-bearing plates 7, which facilitates timely troubleshooting and replacement of damaged wires when a fault occurs in the line. When the wire needs to be fixed, the adjusting screw 3 is rotated, which drives the lifting plate 4 to move up and down. The lifting plate 4 then drives the first pressure plate 5 and the second pressure plate 6 to perform a pressing action. The second pressure plate 6 has a buffering function. When the second pressure plate 6 comes into contact with the wire on the load-bearing plate 7, it can effectively position the wire.

[0026] like Figure 3 and Figure 6 As shown, a guide plate 8 is fixedly connected to the upper inner wall of the first fixed plate 1 and the second fixed plate 2, and a limiting sliding groove 9 matching the lifting plate 4 is provided on the outer side of the guide plate 8, and a first mounting plate 10 is provided at the top center of the first pressure plate 5.

[0027] The lifting plate 4 can be limited and slid by the limiting slide groove 9 to ensure the adjustment direction of the lifting plate 4 and facilitate the clamping of the wire.

[0029] The first hollow plate 11 is connected to the lifting plate 4 , and the first mounting plate 10 is connected to the first pressing plate 5 . The lifting plate 4 and the first pressing plate 5 can be installed by the first bolt, so that the height of the first pressing plate 5 can be adjusted easily.

[0030] like Figure 5 As shown, a circular hole is provided on the top of the first pressure plate 5, and a screw column 12 perpendicular to the second pressure plate 6 passes through the inside of the circular hole. A return spring is sleeved on the outside of the screw column 12, and a screw cap 13 for adjusting the elasticity is threadedly installed at one end of the screw column 12.

[0031] The threaded rod 12 can be installed through the round hole inside the first pressure plate 5. The threaded rod 12 drives the second pressure plate 6. When the threaded cap 13 is rotated, the elastic potential energy of the reset spring can be adjusted according to the degree of rotation of the threaded cap 13, so as to provide a buffer force for the second pressure plate 6 and prevent the second pressure plate 6 from forcibly fixing the wire.

[0032] like Figure 6 As shown, rubber pads 14 are adhered to the surfaces of the second pressure plate 6 and the load-bearing plate 7 that are close to each other.

[0033] The rubber pad 14 can protect the surface of the second pressing plate 6 and the load-bearing plate 7 close to each other, thereby protecting the fixing portion of the outer surface of the wire.

A second mounting plate connected to the load-bearing plate 7 is provided inside the second hollow plate 15. The second mounting plate and the load-bearing plate 7 are connected by a second bolt.

[0035] The second mounting plate can be disassembled and assembled by the second bolt, and the second mounting plate drives the load-bearing plate 7, making it convenient to disassemble and assemble the load-bearing plate 7.

[0036] like Figure 3 As shown, a third hollow plate 16 is symmetrically arranged on one side of the second fixing plate 2. An insert plate 17 connected to the first fixing plate 1 is slidably installed inside the third hollow plate 16. The third hollow plate 16 and the insert plate 17 are connected by auxiliary bolts.

[0037] The second fixing plate 2 drives the third hollow plate 16, and the first fixing plate 1 drives the insertion plate 17. When the insertion plate 17 is inserted into the third hollow plate 16, the horizontal position of the second fixing plate 2 can be adjusted. At the same time, the auxiliary bolts can be used to fix the device, making it convenient for staff to fix different wires.

[0038] like Figure 1 As shown, a working plate 18 is provided on one side of the third hollow plate 16, and a supporting threaded post 19 is passed through the interior of the working plate 18. A nut for limiting the position is provided at one end of the supporting threaded post 19, and a fixing seat 20 is provided at the bottom of the supporting threaded post 19.

[0039] The working plate 18 can support the third hollow plate 16. At the same time, the supporting threaded post 19 runs through the inside of the third hollow plate 16. The supporting threaded post 19 is adapted to the nut. By adjusting the height of the nut, the height of the third hollow plate 16 can be easily adjusted, which is convenient for positioning wires of different heights.

[0040] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
