Description

Technical Field

[0001] This utility model belongs to the field of pipe connection support technology, and specifically relates to a pipe connection support device. Background Technology

[0002] In pipeline system engineering, the connection between pipes relies heavily on welding operations. To ensure welding quality, especially to ensure the concentricity of the two pipe sections, control the weld root gap, and prevent welding deformation, the pipes must be precisely clamped and fixed before welding. Currently, this step usually relies on various pipe wrenches, chain clamps, and even professional pipe external alignment devices.

[0003] However, in actual welding operations, in order to ensure penetration and obtain high-quality welds, welders must be able to perform welding in all positions. In particular, it is necessary to convert the inconvenient overhead welding position to the easy-to-weld flat welding position. This means that after completing spot welding or partial welding of an area, the tightened clamps must be loosened, and the pipe must be rotated manually or with auxiliary equipment to adjust the unwelded area to the optimal position before it can be clamped and fixed again before welding can continue.

[0004] This "clamp-release-rotate-re-clamp" operation mode has significant drawbacks: First, the operation process is cumbersome, and the frequent tightening and loosening of the clamps severely reduces the continuity and overall efficiency of the welding operation, becoming a bottleneck restricting the construction progress; second, re-clamping may cause a slight offset of the pipe center due to human factors, introducing new misalignment risks, which in turn affects the previously adjusted alignment accuracy and welding quality; third, the operation process is not only labor-intensive, but the pipe section is in an unstable state after loosening and before re-fixing, posing certain safety hazards. Utility Model Content

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

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1 - Figure 4 As shown, a pipe connection support device includes: a base plate 1, two symmetrically arranged fixing plates 2 on the top of the base plate 1, the fixing plates 2 being fixedly connected to the base plate 1 by a support rod, the fixing plates 2 being connected to an installation box 4 by a rotating mechanism, the installation box 4 having two symmetrically arranged clamping blocks 5 connected inside by an adjusting component, the outer walls of the two clamping blocks 5 having V-shaped grooves on opposite sides, and the outer walls of the fixing plates 2 and the installation box 4 having openings adapted to the pipe.

[0025] The rotating mechanism includes a rotating seat 3 rotatably mounted on the outer wall of the fixed plate 2. The rotating seat 3 is arranged in a ring shape. The end of the rotating seat 3 away from the fixed plate 2 is fixedly connected to the outer wall of the mounting box 4. The rotating seat 3 is provided with a fixing component, and a transmission component is provided between the two mounting boxes 4.

[0026] As can be seen from the above, by inserting two pipes into the corresponding two mounting boxes 4, the pipes are placed on the clamping blocks 5 at the bottom. The adjusting component drives the two clamping blocks 5 to clamp and fix the pipes through the V-groove. After fixing, the pipes are welded. The fixing component releases the restriction on the rotating mechanism, and the mounting box 4 is rotated. Under the combined action of the transmission component, clamping blocks 5 and adjusting component, the two pipes are rotated simultaneously to adjust the welding position of the pipes. After adjustment, the fixing component restricts the rotating mechanism again, so that the pipes remain stable during welding, ensuring welding quality and improving welding efficiency.

[0027] Specifically, regarding the aforementioned fixing and transmission components, the fixing component includes a first friction plate 6 fixedly sleeved on the outer wall of the rotating seat 3. A movable plate 7 is provided above the rotating seat 3, and a second friction plate 8 is fixedly disposed at the bottom of the movable plate 7. Both the movable plate 7 and the second friction plate 8 are arc-shaped and adapted to the first friction plate 6. The outer wall of the second friction plate 8 is in contact with the outer wall of the first friction plate 6.

[0028] A top plate 9 is fixedly installed on the outer wall of the fixed plate 2. A screw 11 is threaded through and connected to the top plate 9. A rotating block 10 is fixedly installed on the top of the screw 11. The bottom of the screw 11 is rotatably connected to the top of the movable plate 7.

[0029] Multiple limiting rods 12 are fixedly installed on the top of the movable plate 7, and the top of each of the multiple limiting rods 12 passes through the top plate 9 and is fixedly installed with a limiting block;

[0030] The transmission assembly includes mounting plates 18 that are fixedly mounted at the bottom of two mounting boxes 4, and the same transmission rod 19 is slidably mounted through the two mounting plates 18.

[0031] As can be seen from the above, when the pipe needs to be rotated to adjust the welding position, the rotating block 10 is rotated counterclockwise, which drives the screw 11 connected to it to move upward. The bottom of the screw 11 pushes the moving plate 7 and the second friction plate 8 fixed at its bottom away from the first friction plate 6 sleeved on the rotating seat 3. The operator can directly apply torque to the mounting box 4, and the mounting box 4 drives the rotating seat 3 to rotate easily on the fixed plate 2.

[0032] After rotating to the desired optimal welding angle, rotate the rotating block 10 clockwise to drive the screw 11 threaded to it to move downward. The bottom of the screw 11 pushes the moving plate 7 and the second friction plate 8 fixed at its bottom to press tightly against the first friction plate 6 sleeved on the rotating seat 3. Through the huge frictional torque generated between the two sets of arc-shaped friction plates, the rotating seat 3 and the entire mounting box 4 connected to it are firmly locked at the current angle, ensuring the absolute stability of the pipe during the welding process.

[0033] Multiple limit rods 12 penetrate the top plate 9, effectively restricting the movement path of the movable plate 7, ensuring that it only moves vertically without circumferential deflection, greatly improving the stability and reliability of the locking action.

[0034] The transmission rod 19 passes through the mounting plates 18 at the bottom of both mounting boxes 4, forming a rigid linkage mechanism. When rotation is required, operating either mounting box 4 will cause the displacement of that mounting box 4 to drive the other mounting box 4 to rotate via the transmission rod 19. This prevents misalignment of the pipe ends that may be caused by repeated clamping and loosening to adjust the welding position, and provides crucial precision assurance for subsequent high-quality welding.

[0035] Example 2:

[0036] Specifically, regarding the aforementioned adjustment assembly, the adjustment assembly includes an adjustment knob 15 that is rotatably mounted on the top of the mounting box 4. A bidirectional lead screw 16 is fixedly mounted at the bottom of the adjustment knob 15. The bottom of the bidirectional lead screw 16 passes through the top of the mounting box 4 and is rotatably connected to the bottom of the mounting box 4. Two symmetrically arranged adjustment blocks 14 are threadedly connected to the outer wall of the bidirectional lead screw 16.

[0037] Two clamping blocks 5 are fixedly provided with movable plates 13 on the outer side walls of opposite ends. Two adjusting blocks 14 are fixedly connected to the outer side walls of the corresponding two movable plates 13. Multiple guide rods 17 are slidably provided through the two movable plates 13. The ends of the multiple guide rods 17 are fixedly connected to the inner side wall of the mounting box 4.

[0038] As can be seen from the above, the pipe is passed through the opening between the fixing plate 2 and the mounting box 4 and placed between the two clamping blocks 5. The adjustment knob 15 is rotated to drive the bidirectional screw 16 fixed thereto to rotate. Since the two adjustment blocks 14 are engaged with the threaded sections of the bidirectional screw 16 with opposite directions of rotation, the rotation of the bidirectional screw 16 will drive the two adjustment blocks 14 to make precise linear movements in opposite directions along the guide rod 17. The movement of the adjustment blocks 14 is transmitted to the clamping blocks 5 through the movable plate 13 fixed thereto.

[0039] The V-shaped groove structure opened at one end of the two clamping blocks 5 gives it good self-adaptive characteristics and can adapt to pipes of different diameters within a certain range. Multiple guide rods 17 provide high-strength and high-precision guiding constraints for the movement of the movable plate 13 and the clamping blocks 5, effectively preventing them from deflecting, jamming or tilting during movement, and improving clamping stability.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
