Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe surfacing, in particular to a steel pipe surfacing support mechanism. Background Art

[0002] As an economical and fast process for material surface modification, cladding is increasingly used in the manufacture and repair of parts in various industrial sectors. Cladding on the inner wall of steel pipes can improve the strength, corrosion resistance and other properties of steel pipes, thereby meeting the application of steel pipes in various environments.

[0003] A Chinese patent with the authorization announcement number CN204954137U discloses a tool for preventing the inner wall of a steel pipe from moving due to surfacing welding. The tool is installed by combining the V-groove on the driving wheel with the V-shaped boss of the positioning ring. The steel pipe will not move forward or backward during the welding process, and the positioning ring can be put on the appropriate position of the steel pipe and then tightened by tightening the bolts to lock the steel pipe. The above device has the following disadvantages: since there is no interlocking relationship between the V-groove on the driving wheel and the V-shaped boss of the positioning ring, there may be slippage between the driving wheel and the positioning ring when the driving wheel speed is higher, thereby affecting the surfacing effect of the steel pipe; and since each bolt needs to be operated separately, this will cause the central axis of the steel pipe and the central axis of the positioning ring to not coincide, thereby affecting the surfacing quality of the steel pipe. Therefore, it is urgent to study a steel pipe surfacing support mechanism to solve the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] See also Figure 1-3As shown, the utility model is a steel pipe surfacing support mechanism, comprising a horizontally arranged base 1; a support plate 2 is connected to the upper surface of the base 1 by vertical bolts; a bearing tube 3 is horizontally inserted into one side surface of the support plate 2; the bearing tube 3 is rotatably connected to the support plate 2; a steel pipe positioning assembly 4 is mounted on the bearing tube 3 for positioning the steel pipe after the steel pipe is inserted into the bearing tube 3; an outer gear ring 5 is fixedly sleeved on the outer periphery of the bearing tube 3; a pair of rotating shafts 6 parallel to the bearing tube 3 are arranged side by side below the outer gear ring 5; both rotating shafts 6 are rotatably connected to the support plate 2; both rotating shafts 6 are fixedly sleeved with a gear 7 meshing with the outer gear ring 5; the two rotating shafts 6 are connected by a driving assembly 8; the driving assembly 8 can drive the two rotating shafts 6 to rotate synchronously in the same direction. When in use, the steel pipe is inserted into the supporting tube 3, and then the steel pipe positioning component 4 is used to lock the steel pipe. Then, the driving component 8 drives the two rotating shafts 6 to rotate synchronously in the same direction, prompting the rotating shaft 6 to drive the supporting tube 3 to rotate through the gear 7 and the outer gear ring 5. Due to the meshing relationship between the gear 7 and the outer gear ring 5, it can not only ensure the smooth and uniform rotation of the steel pipe, but also effectively ensure the surfacing effect of the steel pipe.

[0025] Example 2:

[0026] Based on Example 1 Figure 2 and Figure 4 As shown, the steel pipe positioning assembly 4 includes a movable cylinder 401 threadedly engaged with the outer periphery of one end of the supporting cylinder 3 and a plurality of positioning columns 402 radially slidingly inserted into the circumferential side wall of the supporting cylinder 3; a conical cylinder 403 is coaxially welded to one end of the movable cylinder 401, and the small end of the conical cylinder 403 is connected to the movable cylinder 401; the inner surface of the conical cylinder 403 is in sliding contact with one end of the plurality of positioning columns 402; the other ends of the plurality of positioning columns 402 are fixed with buffer pads 404 made of rubber; the plurality of buffer pads 404 are connected to the circumferential side walls of the supporting cylinder 3 respectively through tensioning springs 405; and the plurality of tensioning springs 405 are respectively sleeved on the outer peripheries of the plurality of positioning columns 402. When in use, by rotating the movable cylinder 401, the conical cylinder 403 is prompted to move axially along the supporting cylinder 3, so that the conical cylinder 403 pushes multiple positioning columns 402 to approach the steel pipe synchronously, thereby achieving clamping and positioning of the steel pipe, and ensuring that the central axis of the steel pipe coincides with the central axis of the supporting cylinder 3, thereby ensuring the quality of the steel pipe's surfacing.

[0027] Among them Figure 2-3As shown, the drive assembly 8 includes a servo motor 801 horizontally fixed to a side of the support plate 2 and a pair of first pulleys 802 fixedly mounted on the outer peripheries of the two rotating shafts 6.

The second pulleys 803 and the two first pulleys 802 are connected by a synchronous belt transmission. The synchronous belt is connected to a tensioning pulley, which is rotatably connected to the support plate 2. During operation, the servo motor 801 drives the rotating shaft 6 through the second pulleys 803 and the first pulleys 802, thereby driving the steel pipe.

When in use, the bidirectional screw rod 901 is rotated by operating the handle 903, prompting the two screw nuts 904 to move relative to each other, thereby realizing that the U-shaped seat 906 drives the driven roller 10 to move up and down, which can ensure the bearing effect of the driven roller 10 on the steel pipe.
