[0002] The structure for supporting pipelines laid overhead on the ground is a pipeline bracket. As a support structure for pipelines, currently, when laying pipelines on each floor of a building, the position of the pipeline is fixed by a pipeline bracket fixed on the floor, but the pipeline bracket cannot be adjusted, making it difficult to achieve the precise position required for construction.

[0003] After retrieval, the utility model patent with the Chinese patent publication number CN212986276U discloses an adjustable pipeline bracket, which includes a base, a moving plate, a screw rod, a clamping mechanism, two guide rods, and two nuts. The bottom of the guide rod is fixed on the base, a guide sleeve is sleeved on the guide rod, the moving plate is arranged between the two guide sleeves and connects the two guide sleeves; a strip-shaped hole and a rod hole are opened on the moving plate, a scale is arranged on the base, the upper end of the scale passes through the strip-shaped hole, the bottom of the screw rod is fixed on the base, the upper end of the screw rod passes through the rod hole, and the two nuts are both sleeved on the screw rod and are respectively located on the upper and lower sides of the moving plate; the clamping mechanism includes a fixed seat, a hinged assembly, two semi-circular clamps, and three bolts. The end of the bolt is connected with a spring, and an arc-shaped plate is connected to the spring; the device clamps and fixes the pipeline by the mutual approach of multiple arc-shaped plates. However, since it is inconvenient to clamp and fix the clamping position of the pipeline according to the length of the pipeline, the stability of the pipeline bracket for clamping and fixing the pipeline is reduced, and thus an adjustable-length pipeline bracket is proposed.

[0021] Please refer to Figures 1-4 , a length-adjustable bracket, including two moving blocks 1. One end of each of the two moving blocks 1 is fixedly connected with a stabilizing block 2. One end of one of the stabilizing blocks 2 is fixedly connected with a first motor 3. The output end of the first motor 3 is fixedly connected with a rotating screw 4. A rotating nut 5 is screwed on the outer wall of the rotating screw 4. The outer wall of the rotating nut 5 is fixedly connected with a fixed sleeve 6. One end of the fixed sleeve 6 is fixedly connected with one end of one of the stabilizing blocks 2. The tops of the two moving blocks 1 are fixedly connected with a support plate 7. Support grooves are provided at the tops of the two support plates 7. Pipe clamping mechanisms are installed inside the two support grooves. The pipe clamping mechanism includes a second motor 8. The output end of the second motor 8 is fixedly connected with a bi-directional screw 9. The other end of the bi-directional screw 9 is rotatably connected with one end inside the support groove. Two moving nuts 10 are screwed on the outer wall of the bi-directional screw 9. The tops of the two moving nuts 10 are fixedly connected with a moving plate 11. Two buffer through holes are provided at one end of the two moving plates 11. Sliding rods 12 are slidably connected inside the two buffer through holes. A clamping plate 13 is fixedly connected between one ends of the two sliding rods 12. A limiting plate 14 is fixedly connected between the other ends of the two sliding rods 12. Buffer springs 15 are sleeved on the outer walls of the two sliding rods 12. After the second motor 8 is powered on and started, the output end of the second motor 8 will drive its bi-directional screw 9 to rotate. During the rotation of the bi-directional screw 9, the moving nut 10 will be driven to move. During the movement, the two clamping plates 13 will be driven to approach, thereby completing the clamping of the pipe. And through the movement of the sliding rod 12 and the tension of the buffer spring 15, the stability of the pipe clamping is improved. By placing the pipe between the two clamping plates 13, and after the first motor 3 is powered on and started, the output end of the first motor 3 will drive the rotating screw 4 to rotate. During the rotation of the rotating screw 4, the fixed sleeve 6 will be driven to move through the rotating nut 5, and the movement of the two moving blocks 1 will be realized, thereby completing the effect of adjusting the clamping position of the pipe bracket according to the length of the pipe, and further improving the support stability of the pipe bracket.

[0022] It should also be noted that the other ends of the two moving blocks 1 are fixedly connected with limiting plates 16. One end of one limiting plate 16 is fixedly connected with a limiting rod 17, and one end of the other limiting plate 16 is fixedly connected with a limiting sleeve 18. A limiting sliding groove is opened at one end inside the limiting sleeve 18, and a limiting sliding block 19 is slidably connected inside the limiting sliding groove. One end of the limiting sliding block 19 is fixedly connected with one end of the limiting rod 17. By the movement of the limiting rod 17 inside the limiting sleeve 18, the stability of the movement of the two moving blocks 1 is further improved. Two stabilizing casters 20 are fixedly installed at the bottom ends of the two moving blocks 1, further improving the convenience of the movement of the moving blocks 1. Sponge layers 21 are installed at one ends of the two clamping plates 13, improving the stability of the clamping of the pipeline by the clamping plates 13.

[0023] In summary, when the length-adjustable bracket is in use, first place the pipeline between the two clamping plates 13. After the first motor 3 is powered on and started, the output end of the first motor 3 will drive the rotating screw rod 4 to rotate. During the rotation of the rotating screw rod 4, the fixed sleeve 6 is driven to move through the rotating nut sleeve 5, and the movement of the two moving blocks 1 is realized, thereby realizing the movement of the pipeline clamping mechanism. After the second motor 8 is powered on and started, the output end of the second motor 8 will drive its bidirectional screw rod 9 to rotate. During the rotation of the bidirectional screw rod 9, the moving nut sleeve 10 will be driven to move, and during the movement, the two clamping plates 13 will be driven to approach, thereby completing the clamping of the pipeline. And through the movement of the sliding rod 12 and the tension of the buffer spring 15, the stability of the clamping of the pipeline is further improved.
