Description

Technical Field

[0001] This utility model belongs to the technical field of bidirectional seismic-resistant cable supports, specifically relating to an adjustable bidirectional seismic-resistant cable support. Background Technology

[0002] Bidirectional cable supports are essential facilities in power engineering used to support and fix cables. They feature a symmetrical design on both sides, allowing them to support more cables simultaneously compared to unidirectional supports, significantly improving space utilization and making them suitable for densely cabled installations. Their structure consists of columns, brackets, and cross braces, with all components securely connected by bolts or welding, ensuring high stability. Common materials include metals and composite materials. Metal supports offer high strength and load-bearing capacity, while composite material supports are corrosion-resistant, have good insulation, and are lightweight, adaptable to various environmental requirements. During installation, the bracket spacing can be flexibly adjusted according to cable specifications and quantity, facilitating cable laying and maintenance. Furthermore, they effectively prevent cable damage due to mutual compression and entanglement, ensuring the safety and stability of power transmission, and are widely used in substations, tunnels, cable trenches, and other similar locations.

[0003] Currently, existing bidirectional seismic cable supports typically use two symmetrically distributed cable conduits to support more cables during use. However, the positions of the two cable conduits on traditional bidirectional seismic cable supports are often fixed, making it difficult to adjust their positions according to the actual installation of the cables. Adjusting some bidirectional seismic cable supports requires not only specific tools but also a lot of time, thus reducing the practicality of bidirectional seismic cable supports. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable bidirectional seismic-resistant cable bracket, which aims to solve the problem that existing bidirectional seismic-resistant cable brackets typically use two symmetrically distributed cable conduits to support more cables during use. However, the positions of the two cable conduits on traditional bidirectional seismic-resistant cable brackets are often fixed, making it difficult to adjust their positions according to the actual installation of the cables. Adjusting some bidirectional seismic-resistant cable brackets requires not only specific tools but also a lot of time, thus reducing the practicality of the bidirectional seismic-resistant cable bracket.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable bidirectional anti-seismic cable bracket, including a connecting seat, with mounting brackets fixedly connected to the four corners of the outer wall of the connecting seat, a bidirectional threaded rod inserted through one end of the connecting seat, two threaded connecting sleeves threadedly connected to the outer wall of the bidirectional threaded rod, and movable blocks fixedly connected to the outer walls of the two threaded connecting sleeves.

[0006] A connecting block is fixedly connected to the top of the movable block, and a movable plate is fixedly connected to one end of the connecting block. A locking clamp is installed on the top of the movable plate. An adjusting knob is fixedly connected to one end of the bidirectional threaded rod. A cable conduit is provided on the inner side of the locking clamp. A fixing bolt is threaded through the end of the locking clamp. An installation hole is opened on the surface of the movable plate. The locking clamp can form a threaded connection structure with the movable plate through the installation hole and the fixing bolt.

[0007] As a preferred embodiment of the adjustable bidirectional seismic-resistant cable bracket of this utility model, two movable plates are provided, and the two movable plates are symmetrically distributed on the top of the connecting seat.

[0008] As a preferred embodiment of the adjustable bidirectional seismic-resistant cable bracket of this utility model, the through end of the bidirectional threaded rod forms a rotating connection structure with the interior of the connecting seat through a bearing.

[0009] As a preferred embodiment of the adjustable bidirectional anti-seismic cable bracket of this utility model, a guide rod is fixedly connected inside the connecting seat, and one end of the movable block is sleeved on the outer wall of the guide rod.

[0010] As a preferred embodiment of the adjustable bidirectional anti-seismic cable bracket of this utility model, the inner wall of the locking clamp is bonded with an arc-shaped rubber pad, a rubber block is installed on the top of the movable plate, a positioning groove is opened at the bottom of the rubber block, and a positioning protrusion is fixedly connected to the top of the movable plate.

[0011] As a preferred embodiment of the adjustable bidirectional anti-seismic cable support of this utility model, the top of the rubber block has an arc-shaped structure, and the rubber block is located directly below the arc-shaped rubber pad.

[0012] In a preferred embodiment of this utility model of an adjustable bidirectional anti-seismic cable bracket, the dimensions of the positioning groove and the positioning protrusion are adapted to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By adjusting the knob to rotate the bidirectional threaded rod, the two threaded connecting sleeves with external threads can move towards or away from each other along the guide rod under the action of the movable block. As the two movable blocks move, the connecting block at the top will drive the two movable plates to move towards or away from each other, so that the spacing between the cable tubes on the two movable plates can be adjusted, thereby improving the overall practicality.

[0015] By using arc-shaped rubber pads and rubber blocks, when the cable conduit is fixed by locking clamps, the bottom and top of the cable conduit will contact the arc-shaped rubber pads and rubber blocks respectively. The flexibility of the rubber material can act as a buffer for the cable conduit, further improving the shock resistance of the cable bracket. In addition, by using positioning grooves and positioning protrusions, when the positioning protrusion is embedded in the positioning groove at the bottom of the rubber block, it can position the rubber block and prevent it from shifting.

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 Figures 1-4 The present invention provides the following technical solution: an adjustable bidirectional anti-seismic cable bracket, including a connecting seat 1, an mounting bracket 2 fixedly connected to the four corners of the outer wall of the connecting seat 1, a bidirectional threaded rod 3 inserted through one end of the connecting seat 1, two threaded connecting sleeves 4 threadedly connected to the outer wall of the bidirectional threaded rod 3, and movable blocks 5 fixedly connected to the outer walls of the two threaded connecting sleeves 4.

[0024] A connecting block 6 is fixedly connected to the top of the movable block 5. A movable plate 7 is fixedly connected to one end of the connecting block 6. A locking clamp 8 is installed on the top of the movable plate 7. An adjusting knob 9 is fixedly connected to one end of the bidirectional threaded rod 3. A cable tube 10 is provided on the inner side of the locking clamp 8. A fixing bolt 16 is threaded through the end of the locking clamp 8. An installation hole 15 is opened on the surface of the movable plate 7. The locking clamp 8 can form a threaded connection structure with the movable plate 7 through the installation hole 15 and the fixing bolt 16.

[0025] It should be noted that the top of the mounting bracket 2 is provided with threaded holes, and the bidirectional seismic cable bracket can be fixedly installed on the roof by bolts.

[0026] Preferably, there are two movable plates 7, which are symmetrically distributed on the top of the connecting seat 1. The through end of the bidirectional threaded rod 3 is connected to the inside of the connecting seat 1 through a bearing to form a rotating connection structure. A guide rod 17 is fixedly connected inside the connecting seat 1, and one end of the movable block 5 is sleeved on the outer wall of the guide rod 17.

[0027] In practical use, by adjusting the knob 9 to rotate the bidirectional threaded rod 3 clockwise, the two threaded connecting sleeves 4 with their external threads can move towards each other along the guide rod 17 under the action of the movable block 5. As the two movable blocks 5 move, the connecting block 6 at the top will drive the two movable plates 7 to move towards each other together.

[0028] Conversely, by adjusting the knob 9 to rotate the bidirectional threaded rod 3 counterclockwise, the two threaded connecting sleeves 4 with their external threads can move in opposite directions along the guide rod 17 under the action of the movable block 5. As the two movable blocks 5 move, the connecting block 6 at the top will drive the two movable plates 7 to move in opposite directions together, so that the distance between the cable tubes 10 on the two movable plates 7 can be adjusted, thereby improving the overall practicality.

[0029] Preferably, the inner wall of the locking clamp 8 is bonded with an arc-shaped rubber pad 11, the top of the movable plate 7 is equipped with a rubber block 12, the bottom of the rubber block 12 is provided with a positioning groove 13, the top of the movable plate 7 is fixedly connected with a positioning protrusion 14, the top of the rubber block 12 is an arc-shaped structure, and the rubber block 12 is located directly below the arc-shaped rubber pad 11, and the dimensions between the positioning groove 13 and the positioning protrusion 14 are compatible.

[0030] In practical use, with the arc-shaped rubber pad 11 and rubber block 12, when the cable conduit 10 is fixed by the locking clamp 8, the bottom and top of the cable conduit 10 will contact the arc-shaped rubber pad 11 and rubber block 12 respectively. The flexibility of the rubber material can play a buffering role for the cable conduit 10, further improving the shock resistance of the cable bracket. Furthermore, with the positioning groove 13 and positioning protrusion 14, when the positioning protrusion 14 is embedded in the positioning groove 13 at the bottom of the rubber block 12, it can play a positioning role for the rubber block 12 to prevent it from shifting.

[0031] Working principle: First, the bidirectional seismic cable bracket can be fixedly installed in the designated position using the mounting bracket 2. Then, the two cable conduits 10 can achieve bidirectional cable harness support. By adjusting the knob 9 to rotate the bidirectional threaded rod 3, the two threaded connecting sleeves 4 with their external threads can move towards or opposite each other along the guide rod 17 under the action of the movable block 5. As the two movable blocks 5 move, the connecting block 6 at their top will drive the two movable plates 7 to move towards or opposite each other, so that the distance between the cable conduits 10 on the two movable plates 7 can be adjusted. This improves the overall practicality. With the arc-shaped rubber pad 11 and rubber block 12, when the cable conduit 10 is fixed by the locking clamp 8, the bottom and top of the cable conduit 10 will contact the arc-shaped rubber pad 11 and rubber block 12 respectively. The flexibility of the rubber material can play a buffering role for the cable conduit 10, further improving the shock resistance of the cable bracket. Furthermore, with the positioning groove 13 and positioning protrusion 14, when the positioning protrusion 14 is embedded in the positioning groove 13 at the bottom of the rubber block 12, it can play a positioning role for the rubber block 12 and prevent it from shifting.
