Description

Technical Field

[0001] This utility model relates to the field of containment guide tube technology, specifically to an anti-deformation support fixture for welding containment guide tubes. Background Technology

[0002] The containment guide tube is a vertical, cylindrical steel structure with specific openings. These openings are designed to balance pressure, allow gas flow, and facilitate inspection and maintenance. The containment guide tube is vertically and centrally mounted above the pressure vessel to ensure the proper functioning of the internal pressure vessel, effectively enhancing its protection and preventing collision damage.

[0003] Containment guide tubes typically require multiple cylinders to be welded together. However, during the welding process, the guide tubes are prone to ellipticization, local concavity, or out-of-roundness, making it difficult to place the containment guide tubes on the outside of the pressure vessel and affecting their actual use. Therefore, anti-deformation support fixtures are needed to support the inside of the containment guide tubes. Existing support fixtures are integrally welded and cannot be adjusted according to the diameter of the guide tubes, nor can they be adapted to guide tubes with variable diameters. Utility Model Content

[0004] The purpose of this invention is to provide a deformation-resistant support fixture for welding containment guide tubes, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant support fixture for welding a containment guide cylinder, comprising a base plate, the surface of which is fixedly connected to a fixing rod, the top of which is fixedly connected to a top plate, a lifting lug fixedly installed on the top of the top plate, a placement plate on the outer side of the base plate, a bidirectional lead screw mounted on the placement plate, a sliding block on the outer side of the bidirectional lead screw, the sliding block being hinged to one end of a connecting plate, an mounting frame mounted on the other end of the connecting plate, a slot on the side of the mounting frame, a clamping block on the mounting frame, the side of the clamping block being fixedly connected to a clamping plate, and a guide cylinder on the outer side of the base plate.

[0006] Preferably, the placement plate is located between the bottom plate and the top plate, and one end of the fixing rod passes through the placement plate and is fixedly connected to the top plate.

[0007] Preferably, a motor is fixedly mounted on the upper surface of the placement plate, the output end of the motor is connected to the drive gear, the outer side of the bidirectional lead screw is fixedly connected to the driven gear, and the outer side of the drive gear is meshed with the driven gear.

[0008] Preferably, the two sides of the bidirectional lead screw are provided with opposite threads, the sliding blocks are symmetrically distributed on both sides of the bidirectional lead screw, and the sliding blocks are engaged with the outer thread of the bidirectional lead screw through threaded sleeves.

[0009] Preferably, one end of the connecting plate is hinged to the side of the mounting bracket, a push plate is provided inside the mounting bracket, the side of the push plate is fixedly connected to the insertion rod, one end of the insertion rod extends into the slot, the slot is inserted into the card plate, the card plate has an insertion hole, and the insertion rod is movably inserted into the insertion hole.

[0010] Preferably, the connecting plate is fixedly connected to the limiting plate inside, the limiting plate slides with the outer side of the insertion rod through a circular through hole, and an elastic element is installed on the side of the push plate, the elastic element and the insertion rod are located on both sides of the push plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a motor to drive the driven gear to rotate, which in turn causes the bidirectional lead screw to rotate. This, in turn, causes the sliding blocks on both sides to move the connecting plate, which in turn pushes the mounting bracket to move horizontally until the clamping block is in contact with the inner wall of the guide cylinder, thus supporting the guide cylinder and preventing deformation of the guide cylinder during welding. At the same time, by using the connecting plate to push the mounting bracket to move, the clamping block can support and fix guide cylinders of different diameters, thus expanding the scope of practical application.

[0012] 2. This utility model also moves the push plate simultaneously to drive the insertion rod to slide on the limiting plate until the insertion rod disengages from the insertion hole of the card plate, so that the clamping block can be directly disassembled and removed, thereby reducing the difficulty of replacing the clamping block. Different clamping blocks can be replaced to meet the support and fixation of the inner wall of the variable diameter or complex guide cylinder, effectively ensuring the use effect of the clamping block.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a deformation-resistant support fixture for welding a containment guide cylinder, comprising a base plate 1, with several fixed rods 2 fixedly connected to the surface of the base plate 1, and the top of the fixed rods 2 fixedly connected to a top plate 3. A placement plate 4 is located between the base plate 1 and the top plate 3, with one end of each fixed rod passing through the placement plate 4 and fixedly connected to the top plate 3. The placement plate 4 connects and fixes the base plate 1 and the top plate 3 to form an outer frame, thereby fixing the bidirectional lead screw 7 and the clamping block 13. A lifting lug 19 is fixedly installed on the top of the top plate 3, allowing the entire fixture to be lifted and moved, facilitating placement inside the guide cylinder 20. Both the base plate 1 and the placement plate 4 have through holes, and the bidirectional lead screw 7 is hollow inside. The through holes allow the base plate 1 and the placement plate 4 to pass through the outside of the guide rod, ensuring stability of the entire fixture during vertical movement and preventing collisions when placed inside the guide cylinder 20, thus enhancing its practical use. A motor 5 is fixedly mounted on the upper surface of the placement plate 4. The output end of the motor 5 is connected to the drive gear 6. The outer side of the bidirectional lead screw 7 is fixedly connected to the driven gear 8. The outer side of the drive gear 6 is meshed with the driven gear 8. Opposite threads are provided on both sides of the bidirectional lead screw 7. Sliding blocks 9 are symmetrically distributed on both sides of the bidirectional lead screw 7. The sliding blocks 9 are threaded and engaged with the outer threads of the bidirectional lead screw 7 through threaded sleeves. The motor 5 causes the drive gear 6 to rotate, which in turn drives the bidirectional lead screw 7 and the driven gear 8 to rotate. This causes the two sliding blocks 9 on the outer side of the bidirectional lead screw 7 to move synchronously. The sliding blocks 9 drive the connecting plate 10, which causes the mounting bracket 11 to move horizontally until it pushes the clamping block 13 to move to the inner wall of the guide cylinder 20 for support and fixation, thus preventing the guide cylinder 20 from becoming elliptical during welding. The sliding block 9 is hinged to one end of the connecting plate 10, and the other end of the connecting plate 10 is hinged to the side of the mounting frame 11. This ensures that the connecting plate 10 can drive the mounting frame 11 and the clamping block 13 to move horizontally, thus supporting and fixing guide cylinders 20 of different diameters. The mounting bracket 11 has a slot 12 on its side, which contacts the clamping block 13. The side of the clamping block 13 is fixedly connected to the clamping plate 14. The slot 12 is inserted into the clamping plate 14. A guide cylinder 20 is fitted on the outer side of the base plate 1. One end of the connecting plate 10 is hinged to the side of the mounting bracket 11. The mounting bracket 11 is slidably engaged with the push plate 15 through a limiting groove. The push plate 15 can slide inside the mounting bracket 11. The push plates 15 are symmetrically distributed inside the mounting bracket 11. The side of the push plate 15 is fixedly connected to the insertion rod 16. One end of the insertion rod 16 extends into the slot 12. An insertion hole is provided on the slot 14, and the insertion rod 16 is movably inserted into the insertion hole. The connecting plate 10 is fixedly connected to the limiting plate 18. The limiting plate 18 is slidably engaged with the outer side of the insertion rod 16 through a circular through hole. An elastic element 17 is installed on the side of the push plate 15. The elastic element 17 and the insertion rod 16 are located on opposite sides of the push plate 15. Working Principle: During use, the hoisting equipment, in conjunction with the lifting lug 19, moves the overall support fixture into the guide cylinder 20. Then, the motor 5 drives the drive gear 6 to rotate, which in turn drives the double-acting screw 7 and the driven gear 8 to rotate. This causes the two sliding blocks 9 on the outer side of the double-acting screw 7 to move synchronously. The sliding blocks 9 then drive the connecting plate 10, causing the mounting bracket 11 to move horizontally until the clamping block 13 moves to the inner wall of the guide cylinder 20 for support and fixation. This prevents the guide cylinder 20 from becoming elliptical during welding. Similarly, the horizontal movement of the clamping block 13 can support and fix guide cylinders 20 of different diameters, effectively expanding the applicability of the overall fixture. Simultaneously, the push plate 15 can be moved to drive the insertion rod 16 to move on the limiting plate 18 until the insertion rod 16 disengages from the insertion hole on the clamping plate 14. Then, the clamping block 13 can be disassembled. Different clamping blocks 13 can be replaced according to the actual inner diameter of the guide cylinder 20 to meet the support and fixation effect, enhance the convenience of actual use, and meet the use of the variable diameter guide cylinder 20.
