[0001] This utility model relates to the field of power construction technology, specifically to a power duct fixing support. Background Technology

[0002] Electricity ducts are designed to meet the requirements of substation cable entry and exit channels and overhead line burial, and to provide power channels for power supply to plots along the route. Electricity ducts are also known as cable pipes, power cable pipes, cement cable pipes, electricity ducts, and power power ducts. The outstanding features of electricity ducts are high strength and low frictional resistance. They are generally constructed simultaneously with road construction or municipal pipeline construction.

[0003] However, existing power duct fixing supports still have some drawbacks:

[0004] Most existing fixed supports are modular and have a relatively simple structure, making it impossible to support and fix different numbers of matrix array power pipes at the same fixed point. This results in poor flexibility of the fixed supports and makes it inconvenient to fix different numbers of matrix array power pipes. Utility Model Content

[0005] To address the problem that existing power duct fixing supports are inconvenient for supporting and fixing different numbers of matrix array power ducts at the same fixed point, the purpose of this utility model is to provide a power duct fixing support.

[0021] 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.

[0022] Example: Figure 1-6 As shown, this utility model provides a power duct fixing bracket, including a base plate 1 and several fixing seats 2. Each fixing seat 2 has a fixing groove 21, which is semi-circular. An assembly mechanism 3 is provided between the fixing seats 2, and a fixing mechanism 5 is provided between the fixing seats 2 and the base plate 1. By setting the fixing groove 21, the power pipe can pass through the fixing groove 21 during the construction of the power duct. By setting the assembly mechanism 3, the assembly mechanism 3 can assemble multiple fixing seats 2. After the assembly is completed, two adjacent fixing seats 2 in the vertical direction can fix a power pipe, which can facilitate the fixing of power pipes in different matrix arrays. By setting the fixing mechanism 5, the fixing mechanism 5 can fix multiple fixing seats 2 on the base plate 1.

[0023] The assembly mechanism 3 includes several connecting plates 31. Each of the bottom ends of several fixed seats 2 has four connecting slots 32. One end of each of the four connecting plates 31 is movably inserted into the inner wall of the four adjacent connecting slots 32. The upper surface of each of the fixed seats 2 has two grooves 33. Two movable plates 34 are slidably installed on the inner wall of each of the grooves 33. A limit rod 35 is fixedly installed on one side of each of the movable plates 34. The other end of each of the connecting plates 31 has a limit hole 36. One end of one limit rod 35 is movably inserted into the inner wall of a limit hole 36. A fixing rod 37 is fixedly installed on the bottom wall of each of the grooves 33. Cavities 38 are formed at both ends of each fixing rod 37. A spring 4 is fixedly installed at one end of each cavity 38. A spring 4 is fixedly installed at one end of each spring 4. Push rod 39, one end of push rod 39 is fixedly connected to the side of moving plate 34 away from limit rod 35. By setting connecting plate 31, connecting groove 32 and groove 33, two vertically adjacent fixed seats 2 can be connected by connecting plate 31, connecting groove 32 and groove 33. By moving moving plate 34 horizontally in groove 33, moving plate 34 can make limit rod 35 move synchronously. When limit rod 35 is horizontally inserted into limit hole 36, connecting plate 31 can be limited and fixed, thereby realizing the splicing of two vertically fixed seats 2. By setting fixed rod 37, cavity 38, spring 4 and push rod 39, the extension of spring 4 can push moving plate 34 and limit rod 35 to always move horizontally toward the side of limit hole 36 through push rod 39.

[0024] Two ear plates 11 are fixedly connected to both ends of the base plate 1. Each of the four ear plates 11 has a mounting hole 12. By setting the ear plates 11 and the mounting holes 12, the base plate 1 can be fixed to the concrete base at the bottom of the power duct construction pit by means of expansion bolts and mounting holes 12.

[0025] Each of the upper surfaces of several movable plates 34 is fixedly equipped with an L-shaped pull plate 41. By setting the L-shaped pull plate 41, it is convenient for construction personnel to pull the movable plate 34 to move horizontally, so that the limiting rod 35 can be separated from the limiting hole 36, thereby realizing the separation of the two fixed seats 2 in the vertical direction.

[0026] Each of the grooves 33 has two guide grooves 42 on its bottom wall. Each of the guide grooves 42 has a guide block 43 slidably installed at one end. The upper surface of one of the guide blocks 43 is fixedly connected to the lower end face of a moving plate 34. By setting the guide grooves 42 and the guide blocks 43, the guide blocks 43 guide the moving plate 34 in the horizontal direction, so that the moving plate 34 keeps moving in the horizontal direction.

[0027] The assembly mechanism 3 also includes four sealing plugs 44, which are interference-fitted with the top walls of four of the grooves 33. By setting the sealing plugs 44, the sealing plugs 44 can seal the grooves 33 of the upper row of fixing seats 2 to prevent concrete from entering.

[0028] The fixing mechanism 5 includes two movable seats 51, and limiting grooves 52 are provided on both sides of several fixed seats 2. The inner walls of the two movable seats 51 and two of the limiting grooves 52 are in contact with each other. By setting the limiting grooves 52 and the movable seats 51, when the assembled multiple fixed seats 2 are placed in the middle of the base plate 1, the two movable seats 51 are driven to move closer to each other, so that the two movable seats 51 enter the limiting grooves 52 on both sides of the multiple fixed seats 2, thereby fixing the assembled multiple fixed seats 2 and fixing the multiple fixed seats 2 to the base plate 1.

[0029] The upper surface of the base plate 1 is provided with a movable groove 53, and the bottom wall of the movable groove 53 is provided with a sliding groove 54. Both ends of the sliding groove 54 are slidably mounted with sliders 55. The upper surface of one slider 55 is fixedly connected to the lower surface of a movable seat 51. By setting the sliding groove 54 and the slider 55, the slider 55 slides horizontally in the sliding groove 54, thereby enabling the movable seat 51 to move horizontally in the movable groove 53.

[0030] A double-ended screw 56 is rotatably mounted in the middle of the base plate 1. The double-ended screw 56 passes through the movable groove 53 and is threadedly connected to two movable seats 51. A corrugated disk 57 is fixedly mounted on one end of the double-ended screw 56. By turning the corrugated disk 57, the double-ended screw 56 can be rotated. The double-ended screw 56 can drive the two movable seats 51 to move closer to each other or further away from each other.

[0031] Working principle: When it is necessary to support and fix the matrix array power pipeline during the construction of power pipeline, the construction personnel first select the corresponding fixing seat 2 according to the number of matrix array power pipelines, then insert one end of the connecting plate 31 into the connecting groove 32 of one fixing seat 2, and then insert the other end of the connecting plate 31 into the groove 33 of another fixing seat 2, and make the limiting rod 35 in the groove 33 horizontally inserted into the limiting hole 36 at the end of the connecting plate 31. At this time, the two fixing seats 2 are fixed together by the connecting plate 31. Then, according to the above steps, multiple fixing seats 2 are assembled.

[0032] Subsequently, the construction workers fixed the base plate 1 to the concrete base at the bottom of the power duct construction pit using expansion bolts and mounting holes 12, and placed the assembled multiple fixing seats 2 in the middle of the base plate 1. Then, they manually rotated the corrugated plate 57, which caused the double-headed screw 56 to rotate. The double-headed screw 56 drove the two moving seats 51 to move closer to each other, so that the two moving seats 51 entered the limiting grooves 52 on both sides of the two outer fixing seats 2. At this time, the two moving seats 51 fixed the assembled multiple fixing seats 2 to the base plate 1 through the two limiting grooves 52.

[0033] When the matrix array power pipeline is hoisted into the construction pit, the matrix array power pipeline horizontally passes through multiple fixing slots 21. At this time, two adjacent fixing seats 2 in the vertical direction support and fix a single power pipeline, thereby conveniently realizing the support and fixation of different numbers of power pipelines at the same fixing point, making the fixing bracket convenient and flexible, and effectively improving the convenience of supporting different numbers of power pipelines.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
