DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] As described in the background art, in actual applications, the heights of the pipelines from the ground are not the same during the process of laying the pipelines. For this reason, this embodiment provides a height-adjustable support frame, which can be adjusted in height according to needs when in use.

[0025] See also Figures 1 to 4This embodiment proposes a height-adjustable support frame, including a fixed cylinder 1, the inner wall of which is slidably connected to a sliding column 2, see Figure 1 It can be seen that the sliding column 2 can slide inside the fixed cylinder 1, so as to achieve the purpose of adjusting the height of the device. The inner wall of the sliding column 2 is polished, which can reduce the wear caused by the sliding column 2 when sliding, and can effectively increase the service life of the device.

[0026] The bottom end of the fixed tube 1 is fixedly connected to a base plate 8, and threaded holes 9 are provided at the four corners of the upper surface of the base plate 8. The inner wall of each threaded hole 9 is threadedly connected with a bolt 10. The device can be fixed to a desired position through the mutual cooperation between the base plate 8, the threaded hole 9 and the bolt 10, which can effectively increase the stability of the device and avoid damage to the pipeline caused by shaking of the device.

[0027] The outer surface of each bolt 10 is sleeved with a washer 11, and the outer surface of each washer 11 is passivated. The washer 11 can reduce the damage to the fixing tube 1 caused by the rotation of the bolt 10, which can effectively increase the service life of the device. The passivation treatment of the outer surface of the washer 11 can prevent the palm of the staff from being scratched.

[0028] The upper surface of the sliding column 2 is fixedly connected to a fixed box 3, and an adjusting mechanism 4 is arranged inside the fixed box 3. The cooperation between the fixed box 3 and the adjusting mechanism 4 can make it more convenient and quick for the staff to adjust the height of the device. Because the device is in a humid state, the fixed box 3 needs to be made of waterproof and rust-proof material, which can effectively increase the service life of the device.

[0029] The adjustment mechanism 4 includes a first rotating rod 401 rotatably connected to the inner wall of the fixed box 3, the front end of the first rotating rod 401 passes through the fixed box 3 and extends to the outside of the fixed box 3, the outer surface of the first rotating rod 401 is fixedly connected to a ratchet 402, and the inner wall of the fixed box 3 is rotatably connected to a pawl 403 engaged with the ratchet 402.

[0030] See also Figures 2 to 3 When the first rotating rod 401 is rotated counterclockwise, the ratchet 402 can be driven to rotate. At this time, the pawl 403 will not limit the ratchet 402. When the first rotating rod 401 is rotated clockwise, the pawl 403 can be driven to rotate. At this time, the ratchet 402 can be limited by the pawl 403, so the first rotating rod 401 can be limited. The outer surface of the first rotating rod 401 is polished, which can reduce the wear generated when the first rotating rod 401 rotates, and can increase the service life of the device.

[0031] The outer surface of the first rotating rod 401 is fixedly connected to the first pulley 404, the inner wall of the fixed box 3 is rotatably connected to the second rotating rod 405, the outer surface of the second rotating rod 405 is fixedly connected to the second pulley 406, a belt 407 is arranged inside the fixed box 3, the first pulley 404 and the second pulley 406 are connected through the belt 407, the outer surface of the second rotating rod 405 is fixedly connected to the gear 408, the gear 408 is meshed with the sliding column 2, and two clamping mechanisms 6 are arranged above the sliding column 2.

[0032] See also Figures 2 to 3 The rotation of the first rotating rod 401 can drive the first pulley 404 to rotate, and then the second pulley 406 can be driven to rotate through the belt 407. The rotation of the second pulley 406 can drive the second rotating rod 405 to rotate, thereby driving the gear 408 to rotate. As can be seen from the figure, the sliding column 2 is provided with teeth meshing with the gear 408, so the rotation of the gear 408 can drive the sliding column 2 to rise and fall, thereby realizing the adjustment of the height of the device.

[0033] The upper surface of the sliding column 2 is fixedly connected to the lifting plate 5, and the clamping mechanism 6 includes a fixing groove 601 fixedly connected to the upper surface of the lifting plate 5. The inner wall of the fixing groove 601 is rotatably connected to a threaded rod 602, and the left end of the threaded rod 602 passes through the fixing groove 601 and extends to the outside of the fixing groove 601.

[0034] The lifting plate 5 can support the clamping mechanism 6. The outer surface of the threaded rod 602 is polished to reduce the wear caused by the rotation of the threaded rod 602. Because the device works in a humid environment, the fixing groove 601 should be made of waterproof and moisture-proof material, which can effectively increase the service life of the device.

[0035] Furthermore, two threaded blocks 603 are slidably connected to the inner wall of the fixing groove 601 , the inner walls of the holes of the two threaded blocks 603 are threadedly connected to the outer surface of the threaded rod 602 , and the upper surface of each threaded block 603 is fixedly connected to a clamping plate 604 .

[0036] The rotation of the threaded rod 602 can drive the threaded block 603 to move, thereby driving the clamping plate 604 to clamp and fix the pipe. The outer surface of the threaded block 603 is polished, which can reduce the wear caused by the sliding of the threaded block 603 and effectively increase the service life of the device.

[0037] The left end of the threaded rod 602 is fixedly connected to a turntable 605, and the left side of the turntable 605 is fixedly connected to a handle 606. The turntable 605 can make it more convenient for the staff to turn the handle 606. As the handle 606 rotates, the threaded rod 602 can be driven to rotate. The outer surface of the turntable 605 is passivated, which can effectively prevent the staff's palms from being scratched.

[0038] The outer surface of the first rotating rod 401 is fixedly connected with a rotating plate 7, and the outer surface of the rotating plate 7 is passivated. The rotating plate 7 can make it more convenient and quick for the staff to rotate the first rotating rod 401. A protective cover can be wrapped on the outer surface of the rotating plate 7 to increase the comfort of the staff.

[0039] Working principle: When the device is in use, it is first necessary to install the device to the required position through the mutual cooperation between the bottom plate 8, the threaded hole 9 and the bolt 10, and then adjust the height of the device according to the needs, and it is necessary to rotate the rotating plate 7, and the first rotating rod 401 can be driven to rotate through the rotating plate 7, and the ratchet 402 can be driven to rotate with the rotation of the first rotating rod 401, and the first pulley 404 can be driven to rotate at the same time, and the second pulley 406 can be driven to rotate through the belt 407 with the rotation of the first pulley 404, and then the second rotating rod 405 can be driven to rotate, and the second rotating rod 405 can be driven to rotate with the rotation of the second pulley 406. The rotation of the rod 405 can drive the gear 408 to rotate, and then drive the sliding column 2 to rise and fall. At the same time, the ratchet 402 can be limited by the pawl 403, so as to increase the stability of the sliding column 2. After the height adjustment of the sliding column 2 is completed, the pipeline is placed on the lifting plate 5, and then the handle 606 is rotated to drive the turntable 605 to rotate. As the turntable 605 rotates, the threaded rod 602 can be driven to rotate, and then the threaded block 603 can be driven to move. As the threaded block 603 moves, the clamping plate 604 can be driven to clamp and fix the pipeline.
