Description

Technical Field

[0001] This utility model relates to the field of pressure vessel technology, specifically to a device for preventing collapse during welding of a pipe seat and a shell. Background Technology

[0002] Pressure vessels (such as storage tanks) are equipped with a pipeline that serves as an inlet and outlet pipe, or they are equipped with one inlet pipe and one outlet pipe respectively. The inlet and outlet pipes are fixed to the pressure vessel by a pair of flanges. The inlet and outlet pipes are connected to the conveying pipe by another pair of flanges. The inlet and outlet pipes are generally composed of a first pipe seat (for connection to the pressure vessel), a bend, and a second pipe seat (for connection to the conveying pipe). A flange needs to be fixed on both the first and second pipe seats. It is necessary to ensure the perpendicularity and positional relationship between the flange and the inlet and outlet.

[0003] Chinese utility model patent CN206869369U discloses an auxiliary tooling for welding inlet and outlet pipes. Although this auxiliary tooling can position the pipe seat, reduce manpower and improve welding quality, it is relatively cumbersome and inconvenient to use.

[0004] Existing anti-collapse devices for pipe seat and shell welding are prone to collapse of the weld seam due to slow heat dissipation during welding, affecting the appearance quality of the weld. In addition, existing devices are generally large in size, inconvenient to transport and use, and difficult to apply to different types of pipe seats, thus their practicality is low. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Please see Figures 1 to 4 The present invention provides a technical solution for a pipe seat and shell welding anti-collapse device, including a base 1 and a support frame 2 installed on the base 1. A lifting frame 4 is slidably connected inside the support frame 2. A first adjustment mechanism is provided between the lifting frame 4 and the support frame 2. A transverse support 12 is slidably connected to the top outer side of the lifting frame 4. A second adjustment mechanism is installed on the transverse support 12. A rotating slide rail 15 is rotatably connected to the end of the transverse support 12.

[0026] The first adjustment mechanism consists of a fixed seat 6, a lifting seat 7, a transmission screw 8, a rotating seat 9, and a first handwheel 10. The second adjustment mechanism consists of a bidirectional threaded rod 13 and a second handwheel 14.

[0027] The support frame 2 is vertically arranged with the base 1. A groove 5 is provided on the outer wall of the support frame 2. The lifting frame 4 is inserted into the groove 5. The fixed seat 6 is fixedly connected to the outer wall of the support frame 2. The lifting seat 7 is fixedly connected to the outer wall of the lifting frame 4, and the fixed seat 6 is located directly below the lifting seat 7.

[0028] The rotating seat 9 is installed on the top of the fixed seat 6, the bottom of the transmission screw 8 is rotatably connected to the rotating seat 9, the transmission screw 8 passes through the lifting seat 7 and is threadedly connected to the lifting seat 7, and the first handwheel 10 is installed on the top of the transmission screw 8.

[0029] The two ends of the bidirectional threaded rod 13 are rotatably connected to the top of the outer wall of the lifting frame 4. The bidirectional threaded rod 13 is perpendicular to the transmission screw 8. The bidirectional threaded rod 13 is provided with two sets of threads of the same length and pitch but opposite directions. The transverse bracket 12 is provided with two sets and is symmetrically installed on the bidirectional threaded rod 13 and threadedly connected to the bidirectional threaded rod 13. The second handwheel 14 is installed at the end of the bidirectional threaded rod.

[0030] Specifically, when welding pipe seats, since pipe seats are generally heavy, manual handling during welding can easily cause shaking, affecting the welding effect and requiring considerable effort from the operator. Therefore, this auxiliary tooling is used to facilitate pipe seat welding. In use, the pipe seat is placed between the rotating slide rails 15 on the two sets of transverse supports 12. Then, the second handwheel 14 is rotated, which drives the bidirectional threaded rod 13 to rotate, causing the transverse supports 12 on the bidirectional threaded rod 13 to move relative to each other and clamp the pipe seat. In addition, by rotating the first handwheel 10, the first handwheel 10 drives the transmission screw 8 to rotate, causing the lifting seat 7 to move the lifting frame 4 on the support frame 2, adjusting the height of the pipe seat and moving it to the welding position.

[0031] The device is easy to operate and can clamp and move tubes of different specifications, making it widely applicable.

[0032] Example 2

[0033] Please see Figure 3 and Figure 5 A limiting component is provided between the rotating slide rail 15 and the transverse support 12. A cooling pipe 19 is detachably installed on the rotating slide rail 15. Symmetrically arranged side handles 11 are installed on the outer surface of the lifting frame 4. The rotating slide rail 15 and the transverse support 12 are hinged. The limiting component consists of an external slide groove 16 opened on the outer wall of the transverse support 12 and a sliding top plate 17 slidably arranged inside the external slide groove 16. The sliding top plate 17 is L-shaped. The top surface of the end of the sliding top plate 17 is flush with the bottom surface of the rotating slide rail 15 when it is rotated to be horizontal with the transverse support 12.

[0034] The rotating slide rail 15 has an internal slide rail 18, and the bottom of the cooling pipe 19 is equipped with a sliding support 23. The bottom end of the sliding support 23 slides inside the external slide groove 16. The cooling pipe 19 has multiple flange-shaped baffles 22 inside, and the inner thickness of the cooling pipe 19 is less than the outer thickness.

[0035] Specifically, during overall welding, a cooling pipe 19 is installed inside the outer groove 16 of the rotating slide rail 15, and cooling water is injected into the cooling pipe 19 through the water inlet pipe 20. The cooling water flows inside the cooling pipe 19 and is then subjected to the action of the baffle 22, resulting in a longer residence time inside the cooling pipe 19 and better heat dissipation on the inner side of the cooling pipe 19. This greatly shortens the cooling time at the weld, preventing the collapse of the weld between the pipe seat and the shell and affecting the appearance quality of the weld. In addition, when this auxiliary tooling is not needed, the sliding top plate 17 can be slid inside the outer groove 16 so that the sliding top plate 17 does not abut against the bottom of the rotating slide rail 15. At this time, the rotating slide rail 15 can rotate, reducing the space occupied during storage and making it easy to store. Furthermore, the auxiliary tooling can be easily moved by the side handle 11, improving the ease of use of the auxiliary tooling.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
