Description

Technical Field

[0001] This utility model relates to the field of pipe surface processing technology, specifically to an internal support device for pipe surface processing. Background Technology

[0002] A pipeline is a device consisting of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. Pipelines have a wide range of applications, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations.

[0003] During pipeline production, the outer wall of the pipeline needs to be coated and processed. Existing pipeline internal support devices generally support both ends together. This support method can easily cause the pipeline to bend downward in the middle, preventing the pipeline from forming a straight line. Furthermore, this method is not convenient for the pipeline to be moved out, reducing the efficiency of pipeline removal and making it inconvenient for users.

[0004] To address the aforementioned problems, an improved internal support device for pipe surface machining is now designed. Utility Model Content

[0005] The purpose of this invention is to provide an internal support device for processing the outer surface of pipes, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An internal support device for pipe surface processing includes a fixed box, a bracket installed on the upper side wall of the fixed box, a fixed plate vertically installed on one side of the upper end of the fixed box, the upper end of the fixed plate being installed on the top of the bracket, a controller installed on the side wall of the fixed plate, a fixed cylinder for placing the pipe horizontally installed on the fixed plate, and several sets of sliding grooves opened on the side wall of the fixed cylinder on one side of the fixed plate, each set of sliding grooves including several sliding grooves, the sliding grooves of the same set being arranged in a circumferential array around the central axis of the fixed cylinder, a support mechanism for supporting the inner wall of the pipe provided on the sliding groove, and a limiting rotation mechanism for limiting the two ends of the pipe and rotating the pipe provided on the top of the fixed plate and the bracket.

[0008] As a further embodiment of this utility model: the support mechanism includes a sliding rod, which is slidably connected to the inner wall of the fixed cylinder. One end of the sliding rod near the fixed plate passes through the fixed cylinder and is fitted with a connecting plate. A third hydraulic telescopic rod for moving the connecting plate is horizontally installed on the side wall of the fixed plate, and the output end of the third hydraulic telescopic rod is installed on the side wall of the connecting plate.

[0009] A fixing column is installed on the side wall of the fixing cylinder near the fixing plate of the slide groove. The fixing column is perpendicular to the fixing cylinder. A telescopic cylinder is slidably sleeved on the side wall of the fixing column. A ball bearing is installed on the end of the telescopic cylinder away from the fixing cylinder.

[0010] A slider that works with a sliding groove is installed on the side wall of the sliding rod. The end of the slider away from the sliding rod passes through the sliding groove and is rotatably connected to a swing rod via a hinge. The end of the swing rod away from the slider is rotatably connected to the side wall of the telescopic cylinder via a hinge.

[0011] As a further embodiment of this utility model: the limiting rotation mechanism includes a linear motion module. Several first rollers, arranged in a circular array around the fixed cylinder on the side wall of the fixed plate near the slide groove, are used to assist the rotation of the pipe. The linear motion module is mounted on the top of a bracket directly above the fixed cylinder, and is parallel to the fixed cylinder. A first hydraulic telescopic rod is vertically mounted at the output end of the linear motion module. A mounting plate is horizontally mounted at the output end of the first hydraulic telescopic rod. A gearbox is mounted at the lower end of the mounting plate. A motor is mounted at the output end of the gearbox. A friction drive wheel, which presses against the inner wall of the pipe and drives the pipe to rotate, is mounted at the output end of the gearbox. A second roller, which works in conjunction with the first rollers to limit the pipe's movement and assist its rotation, is mounted on the mounting plate above the friction drive wheel.

[0012] As a further improvement of this utility model, support plates for supporting and fixing the fixed cylinder are installed on the upper and lower ends of the fixed cylinder sidewall on the side of the fixed plate away from the slide groove.

[0013] As a further improvement of this utility model, the side wall of the swing rod is equipped with reinforcing support ribs to improve the structural strength of the swing rod.

[0014] As a further embodiment of this utility model: a plurality of second hydraulic telescopic rods are vertically installed on the upper end of the fixed box, and a support frame for supporting the fixed cylinder is installed at the output end of the second hydraulic telescopic rods. The plurality of second hydraulic telescopic rods are arranged between two adjacent sliding groove groups.

[0015] As a further improvement of this utility model, a rubber pad is installed on the upper end of the support frame to facilitate the support frame to support the fixed cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention improves the efficiency of pipe movement by moving the pipe in and out from one end of the fixed cylinder, and avoids other equipment from touching the freshly sprayed and undried outer wall of the pipe, thus ensuring the coating effect on the outer wall of the pipe.

[0018] This invention uses a movable sliding rod to drive a swing rod to swing, which in turn drives a telescopic cylinder and ball bearings to move, thereby enabling the ball bearings to support the inner wall of the pipe. It can support pipes of different inner diameters, improving the efficiency and applicability of pipe inner wall support.

[0019] In this invention, as the end of the pipe that is away from the fixed cylinder is completely fitted onto the fixed cylinder, the second hydraulic telescopic rod is gradually retracted to release the support frame from the fixed cylinder. Conversely, as the pipe is removed, the second hydraulic telescopic rod is gradually extended to support the fixed cylinder, thus preventing the pipe from bending the fixed cylinder due to the lever principle when it is fitted onto the fixed cylinder, thereby protecting the fixed cylinder.

The upper end of the fixed plate 2 is installed on the top of the bracket 6. A controller 3 is installed on the side wall of the fixed plate 2. A fixed cylinder 16 for placing the pipe is horizontally installed on the fixed plate 2. A plurality of sliding groove groups are opened on the side wall of the fixed cylinder 16 on one side of the fixed plate 2. Each sliding groove group includes several sliding grooves 20. The sliding grooves 20 in the same group are arranged in a circular array around the central axis of the fixed cylinder 16. A support mechanism for supporting the inner wall of the pipe is provided on the sliding groove 20. Support plates 18 for supporting and fixing the fixed cylinder 16 are installed on the upper and lower ends of the side wall of the fixed cylinder 16 on the side of the fixed plate 2 away from the sliding groove 20. A limiting and rotating mechanism for limiting the two ends of the pipe and rotating the pipe is provided on the top of the fixed plate 2 and the bracket 6.

[0027] Several second hydraulic telescopic rods 15 are vertically installed on the upper end of the fixed box 1. The output end of the second hydraulic telescopic rods 15 is equipped with a support frame 14 for supporting the fixed cylinder 16. Several second hydraulic telescopic rods 15 are arranged between two adjacent sliding groove groups. During the process of the pipe and the end of the fixed cylinder 16 away from the fixed plate 2 being completely fitted onto the fixed cylinder 16, the second hydraulic telescopic rods 15 are gradually retracted to release the support frame 14 from supporting the fixed cylinder 16, so as to avoid the pipe bending the fixed cylinder 16 due to the lever principle when the pipe is just fitted onto the fixed cylinder 16.

[0028] The support mechanism includes a sliding rod 19, which is slidably connected to the inner wall of the fixed cylinder 16. One end of the sliding rod 19 near the fixed plate 2 passes through the fixed cylinder 16 and is fitted with a connecting plate 4. A third hydraulic telescopic rod 17 for moving the connecting plate 4 is horizontally installed on the side wall of the fixed plate 2. The output end of the third hydraulic telescopic rod 17 is installed on the side wall of the connecting plate 4.

[0029] A fixing post 23 is installed on the side wall of the fixing cylinder 16 near the fixing plate 2 of the sliding groove 20. The fixing post 23 is perpendicular to the fixing cylinder 16. A telescopic cylinder 7 is slidably sleeved on the side wall of the fixing post 23. A ball bearing 8 is installed on the end of the telescopic cylinder 7 away from the fixing cylinder 16.

[0030] A slider 21 that works with the slide groove 20 is installed on the side wall of the sliding rod 19. The end of the slider 21 away from the sliding rod 19 passes through the slide groove 20 and is rotatably connected to the swing rod 22 by a hinge. The end of the swing rod 22 away from the slider 21 is rotatably connected to the side wall of the telescopic cylinder 7 by a hinge.

[0031] When in use, the third hydraulic telescopic rod 17 is activated. The output end of the third hydraulic telescopic rod 17 drives the connecting plate 4 to move. The connecting plate 4 drives the sliding rod 19 to move. The sliding rod 19 drives the slider 21 to move. The slider 21 drives the swing rod 22 to swing. Under the action of the hinge, the swing rod 22 drives the telescopic cylinder 7 to slide along the side wall of the fixed column 23. The telescopic cylinder 7 drives the ball bearing 8 to move, so that the ball bearing 8 supports the inner wall of the pipe.

[0032] The limiting rotation mechanism includes a linear motion module 10. Several first rollers 5, which assist the rotation of the pipe, are installed in a circular array around the fixed cylinder 16 on the side wall of the fixed plate 2 near the slide groove 20. The linear motion module 10 is installed on the top of the bracket 6 directly above the fixed cylinder 16. The linear motion module 10 and the fixed cylinder 16 are parallel to each other. A first hydraulic telescopic rod 11 is vertically installed at the output end of the linear motion module 10. An installation plate 24 is horizontally installed at the output end of the first hydraulic telescopic rod 11. A gearbox 13 is installed at the lower end of the installation plate 24. A motor 12 is installed at the output end of the gearbox 13. A friction drive wheel 9 is installed at the output end of the gearbox 13, which presses against the inner wall of the pipe and drives the pipe to rotate. A second roller 25, which works with the first rollers 5 to limit the pipe and assist the pipe rotation, is installed on the installation plate 24 above the friction drive wheel 9.

[0033] After the inner wall of the pipe is properly supported, the linear motion module 10 is activated. The output end of the linear motion module 10 drives the first hydraulic telescopic rod 11, the mounting plate 24, the gearbox 13, the motor 12, the friction drive wheel 9, and the second roller 25 to move, thereby moving the friction drive wheel 9 into the pipe and pressing the second roller 25 tightly against the end of the pipe side wall. Then, the first hydraulic telescopic rod 11 is activated to retract, which drives the mounting plate 24, the gearbox 13, the motor 12, the friction drive wheel 9, and the second roller 25 to move, pressing the friction drive wheel 9 tightly against the inner wall of the pipe. Then, the motor 12 is activated, and the output end of the motor 12 drives the friction drive wheel 9 to rotate through the gearbox 13. The friction drive wheel 9 drives the pipe to rotate, which facilitates the processing of the pipe's outer surface.

[0034] Working principle of internal support device for pipe surface processing:

[0035] The workers put the pipe onto the fixed cylinder 16 from the end away from the fixed plate 2. During this process, the second hydraulic telescopic rod 15 is gradually retracted to release the support frame 14 from the fixed cylinder 16.

[0036] Then, the third hydraulic telescopic rod 17 is extended. The output end of the third hydraulic telescopic rod 17 drives the connecting plate 4 to move. The connecting plate 4 drives the sliding rod 19 to move. The sliding rod 19 drives the slider 21 to move. The slider 21 drives the swing rod 22 to swing. Under the action of the hinge, the swing rod 22 drives the telescopic cylinder 7 to slide along the side wall of the fixed column 23. The telescopic cylinder 7 drives the ball bearing 8 to move, so that the ball bearing 8 supports the inner wall of the pipe.

[0037] Then, the linear motion module 10 is activated. The output end of the linear motion module 10 drives the first hydraulic telescopic rod 11, the mounting plate 24, the gearbox 13, the motor 12, the friction drive wheel 9, and the second roller 25 to move, thereby moving the friction drive wheel 9 into the inside of the pipe and pressing the second roller 25 tightly against the end of the pipe side wall. Then, the first hydraulic telescopic rod 11 is activated to retract. The first hydraulic telescopic rod 11 drives the mounting plate 24, the gearbox 13, the motor 12, the friction drive wheel 9, and the second roller 25 to move, so that the friction drive wheel 9 presses tightly against the inner wall of the pipe. Then, the motor 12 is activated. The output end of the motor 12 drives the friction drive wheel 9 to rotate through the gearbox 13. The friction drive wheel 9 drives the pipe to rotate, which facilitates the processing of the pipe surface.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
