Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation, in particular to a pipeline installation height-adjusting device. Background Art

[0002] When installing pipes, especially when connecting pipes at high positions, it is not practical to lift them with manpower alone. At this time, a height-adjustable pipe installation device is used. Since the cross-section of the pipe is circular and has poor stability, if the pipe is not completely fixed during the continuous rise, it is easy to shake and there is a risk of falling, which is dangerous. Different pipe diameters have different curvatures on the outer surface of the pipe, while the curvature of the splint is fixed. As a result, when clamping pipes of different diameters, it is necessary to disassemble the clamping parts and assemble the appropriate clamping parts to fix the steam pipes of different diameters more snugly and prevent the pipes from sliding when adjusting the height, which wastes a lot of time on replacing the clamping parts.

[0024] Please refer to Figure 1-6 A pipeline installation height adjustment device includes a base 1, a lifting mechanism 2 disposed at the top of the base 1, a lifting platform 3 disposed at the top of the lifting mechanism 2, and a clamping mechanism 4 disposed at the top of the lifting platform 3. The clamping mechanism 4 is used to clamp a round pipe 5 to be installed. The lifting mechanism 2 drives the lifting platform 3 to move the clamping mechanism 4 up and down. The round pipe 5 is fixed by the clamping mechanism 4, and the lifting mechanism 2 controls the lifting and lowering of the lifting platform 3, thereby controlling the installation height of the pipeline.

[0025] Specifically, the clamping mechanism 4 includes a center frame 41, a movable column 42, a rotating rod 1 43, a rotating rod 2 44 and a cylinder 45. The center frame 41 is a hollow frame with upper and lower openings, and a fixed block 1 411 and a fixed block 2 412 are arranged inside. In order to limit the moving direction of the movable column 42, the movable column 42 is vertically slidably arranged at the center of the fixed block 1 411 and the fixed block 2 412. In order to drive the movement of the movable column 42, the cylinder 45 is fixedly arranged at the top of the lifting platform 3, and the bottom end of the movable column 42 is arranged at the output end of the cylinder 45. The rotating rod 1 43 and the rotating rod 2 44 are both rotatably arranged in the center frame 41.

[0026] In order to limit the moving range of the movable column 42 , the fixing block 1 411 is set on the top of the center frame 41 , the fixing block 2 412 is set in the middle of the center frame 41 , and the cylinder 45 is set at the bottom of the center frame 41 .

[0027] In order to drive the rotation of rotating rod 1 43 and rotating rod 2 44, a driving block 421 is fixedly set in the middle of the movable column 42, and a clamping wheel 1 422 is rotatably set at the top. The driving block 421 is located between the fixed block 1 411 and the fixed block 2 412 and has a trapezoidal shape.

[0028] In order to drive the rotation of the rotating rod 43, the rotating rod 43 includes a clamping rod 431 and a driving rod 432. The top end of the clamping rod 431 is rotatably provided with a clamping wheel 4311, and the bottom end of the driving rod 432 is provided with a driving wheel 4321.

[0029] In order to drive the rotation of the second rotating rod 44, the second rotating rod 44 includes a second clamping rod 441 and a second driving rod 442. The top end of the second clamping rod 441 is rotatably provided with a third clamping wheel 4411, and the bottom end of the second driving rod 442 is provided with a second driving wheel 4421.

[0030] In order to make the rotating rod 1 43 and the rotating rod 2 44 move symmetrically, the clamping rod 1 431 and the clamping rod 2 441 are symmetrically arranged, and the driving rod 1 432 and the driving rod 2 442 are symmetrically arranged.

[0031] In order to synchronously drive the rotating rod 1 43 and the rotating rod 2 44 , the driving wheel 1 4321 and the driving wheel 2 4421 are symmetrically arranged on the inclined surfaces on both sides of the driving block 421 .

[0032] When the clamping mechanism 4 is in use, the cylinder 45 pushes the movable column 42 to move upward, and the movable column 42 drives the driving block 421 to move upward as well. The driving block 421 moves upward and drives the driving wheels 1 4321 and 2 4421 on both sides to move away from the movable column 42. The driving wheel 1 4321 drives the rotating rod 1 43 to rotate, thereby driving the clamping rod 1 431 and the clamping wheel 2 4311 to move toward the direction of the axis of the movable column 42. The driving wheel 2 4421 drives the rotating rod The second 44 rotates, thereby driving the clamping rod 2 441 and the clamping wheel 3 4411 to move toward the direction close to the axis of the movable column 42. At the same time, the movable column 42 drives the clamping wheel 1 422 to move upward, and the clamping wheel 1 422, the clamping wheel 2 4311 and the clamping wheel 3 4411 jointly clamp the round tube 5; conversely, when the driving cylinder 45 drives the movable column 42 to move downward, the above movement process is reversed, and the clamping wheel 1 422, the clamping wheel 2 4311 and the clamping wheel 3 4411 release the round tube 5. The driving cylinder 45 drives the driving block 421 to move up and down, thereby driving the clamping wheel 1 422 to move up and down, and at the same time drives the clamping wheel 2 4311 and the clamping wheel 3 4411 to approach and move away, so that the clamping wheel 1 422, the clamping wheel 2 4311 and the clamping wheel 3 4411 can clamp the round tubes 5 of different diameters in a close manner without replacing the clamping parts, and can also maintain stability during the adjustment process of the lifting mechanism 2.

[0033] To achieve the lifting and lowering movement of the round tube 6, the lifting mechanism 2 is a scissor-fork type connecting rod lifting structure driven by a hydraulic cylinder. In another possible embodiment, the lifting mechanism 2 can also be a cylinder-driven lifting mechanism. Both the hydraulic cylinder-driven scissor-fork type connecting rod lifting mechanism and the cylinder-driven lifting mechanism are existing mechanisms and will not be described in detail here.

[0034] When the pipeline installation height adjustment device needs to be used, the lifting mechanism 2 drives the lifting platform 3 to descend to a position convenient for placing the round tube 6, and the round tube 6 is placed on the clamping mechanism 4. After the round tube 6 is placed, the clamping mechanism 4 is controlled by the cylinder 45 to clamp the round tube 6. Then the lifting mechanism 2 drives the lifting platform 3 to drive the clamping mechanism 4 and the round tube 5 to rise to the height required for installation. After the round tube 6 is installed, the clamping mechanism 4 is controlled by the cylinder 45 to loosen the round tube 6. The device does not require replacement of the clamp for round tubes 6 of different diameters, and is quick and easy to use.
