Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary devices for spherical tank production, and specifically to an auxiliary device for welding spherical tank flaps. Background Technology
[0002] Spherical tanks are large pressure vessels widely used in the storage of petrochemical products. During production, due to their large size, two sets of spherical tanks are usually welded together. The quality of the welding directly affects the quality of the tank. Due to their large size, direct welding is not possible during the welding process, and auxiliary devices are required.
[0003] Common welding equipment consists of a raised support platform that supports workers to the processing area of the flasks. However, different spherical tanks have different sizes, and the welding positions of the flasks will also vary. Common auxiliary devices have fixed structures, and for different spherical tanks, corresponding auxiliary devices need to be rebuilt, which cannot be adjusted in time, making operation cumbersome and affecting construction efficiency. Moreover, the ground conditions during construction also affect the equipment. When facing a sloping ground, the equipment will tilt, and the sloping auxiliary support structure is not conducive to workers' stability, which also affects the workers' construction efficiency. In addition, during welding construction, equipment needs to be changed frequently. Common platform structures are simple. When placing equipment or materials, materials are placed on the platform. When workers use it, they need to bend over or squat down to pick up the equipment, which is inconvenient due to frequent operations.
[0004] Patent CN222779058 U discloses an auxiliary device for welding spherical tank segments, including a support assembly. The support assembly includes a slide rail and a mounting platform. The slide rail is set on a bearing plane, and the mounting platform is slidably connected to the slide rail, allowing the mounting platform to move radially along the spherical tank. When using this auxiliary device for welding spherical tank segments, operators can stand on the mounting platform to perform welding, inspection, and grinding. The mounting platform is slidably connected to the slide rail, allowing it to move radially along the spherical tank. Thus, the mounting platform can be adjusted in position on the slide rail based on the diameter of the spherical tank to accommodate welding, inspection, and grinding needs of spherical tanks of different diameters, eliminating the need for repeated disassembly and reassembly of scaffolding, reducing spherical tank manufacturing time, and thus improving manufacturing efficiency. However, a problem exists: it is directly assembled and cannot be adjusted vertically; it can only be adjusted radially. If height adjustment is required, the platform needs to be reassembled. Summary of the Invention
[0005] In view of this, in order to solve the technical problem that the auxiliary device in the existing technology has a simple structure and is inconvenient to use, an auxiliary device for welding spherical tank lobes is provided.

The inclination adjustment frame includes a support plate, a wedge-shaped inclined plate is provided on the support plate, a groove is provided at the wedge opening of the inclined plate, and an adjustment cylinder is provided on the support plate. The adjustment cylinder passes through the groove of the inclined plate and is connected to the bottom of the support plate.
[0007] Furthermore, the lifting frame consists of a pair of symmetrically arranged diamond-shaped lifting frames, which are raised and lowered by a lifting cylinder.
[0008] Furthermore, the bottom of the support plate is provided with a mating groove that cooperates with the adjusting cylinder. The movable end of the adjusting cylinder is provided with a U-shaped contact frame, and a contact wheel is provided on the contact frame, which contacts the bottom surface of the support plate.
[0009] Furthermore, the thick end of the inclined frame is provided with protruding limiting ears on both sides, and the bearing plate is locked in the two limiting ears.

[0013] Furthermore, the bottom of the support plate is symmetrically provided with two strip grooves and two connectors. Each of the two strip grooves contains a sliding block. The top ends of a pair of diamond-shaped lifting frames are connected to the two connectors and the sliding blocks, respectively.
[0014] Furthermore, the bottom of the movable seat is equipped with casters.
[0015] Furthermore, a shaft is provided on the contact frame, and a contact wheel is provided on the shaft.
[0016] Compared with the prior art, the advantages of this utility model are as follows: 1. This utility model achieves height and inclination adjustment by setting up a lifting cylinder and an inclination adjustment frame. When workers are carrying out construction, the lifting cylinder can drive the lifting frame to extend and retract according to the construction needs of different tanks, thereby adjusting the height of the support structure to meet the welding work requirements at different heights. When encountering a ground slope, the bearing plate can be adjusted by adjusting the cylinder according to the slope of the equipment working position to achieve the levelness of the bearing plate, keep the structure stable, facilitate workers to carry out welding, and improve work efficiency.
[0017] 2. This utility model provides a protective structure by combining a protective fence with a support plate, and a placement support structure by combining a rotating seat with a placement rack. The support rod provides support capacity, making the placement rack stable on the protective fence and allowing it to rotate. This facilitates the storage of the placement rack and makes it convenient for workers to place welding tools or raw materials while they are working. Workers can directly pick up the equipment from within their reach without having to squat down to retrieve it, which is convenient for workers and improves work efficiency.

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] This embodiment provides an auxiliary device for welding the petals of a spherical tank, such as... Figures 1-5 As shown, it includes a movable seat 1, the upper surface of the movable seat 1 is disposed on a lifting frame 6, the lifting frame 6 is provided with an inclination adjustment frame, the inclination adjustment frame is provided with a bearing plate 9, and a protective fence 13 is fixed on the bearing plate 9.
[0024] like Figure 2 As shown, in this embodiment, the lifting frame 6 is a pair of diamond-shaped lifting frames arranged symmetrically, and is driven by the lifting cylinder 5 to achieve raising and lowering.
[0025] In this embodiment, the lifting frame 6 is a pair of diamond-shaped lifting frames arranged symmetrically, but other lifting structures can also be used.
[0026] like Figure 4 and Figure 5 As shown, the inclination adjustment frame includes a support plate 7, on which a wedge-shaped inclined plane frame 8 is provided. A groove is provided at the wedge opening of the inclined plane frame 8. An adjusting cylinder 10 is provided on the support plate 7, passing through the groove of the inclined plane frame 8 and connecting to the bottom of the support plate 9. A U-shaped contact frame 11 is provided at the working end of the adjusting cylinder 10. A shaft 25 is provided on the contact frame 11, and a contact wheel 12 is provided on the shaft 25, contacting the bottom surface of the support plate 9 via the contact wheel 12. Two strip-shaped sliding grooves and two connecting pieces are symmetrically arranged at the bottom of the support plate 7. Sliding blocks 23 are respectively provided in the two strip-shaped sliding grooves 22. The top ends of a pair of rhomboid lifting frames are connected to the two connecting pieces and the sliding blocks 23 respectively. A mating groove 24 is provided at the bottom of the support plate 9 to cooperate with the adjusting cylinder 10, and the contact wheel 12 is located within the mating groove 24.
[0027] The inclined frame 8 has protruding limiting ears 4 on both sides of its thick end, and the two ends of the bearing plate 9 are locked in the two limiting ears 4.
[0028] like Figure 1 and 3 As shown, the protective fence 13 is equipped with a placement rack 15 and a level 27. The protective fence 13 also has an entrance / exit gate 19, with a U-shaped connecting lug 20 hinged to it. One end of the connecting lug 20 engages with the protective fence 13 to lock the entrance / exit gate 19. A climbing ladder 21 is provided at one end of the entrance / exit gate 19. The placement rack 15 is hinged to the protective fence 13 via a rotating seat 14. A limiting block 18 is provided under the rotating seat 14 on one side of the placement rack 15, and a support rod 16 is provided on the other side. The support rod is movably supported on the bearing plate 9. The placement rack 15 is leveled by the limiting block 18 and the support rod 16.
[0029] like Figure 1 As shown, the bottom of the movable seat 1 is equipped with movable wheels 3.
[0030] The working process of this embodiment: The movable seat 1 provides a support structure, and the rotating support of the movable wheel 3 enables the equipment to move. This causes the lifting cylinder 5 to work, moving the lifting frame 6 horizontally, thereby enabling the lifting frame 6 to extend and retract, and carrying the support plate 7 onto the frame. This allows for adjustment of the support height to meet welding processing requirements at different heights.
[0031] The inclined frame 8 serves as a connector, allowing the support plate 7 to cooperate with the bearing plate 9, supporting the bearing plate 9 so that the bearing plate 9 can carry the worker. When the equipment is on uneven ground, it will tilt. The control and adjustment cylinder 10 will work, causing the adjustment cylinder 10 to lift and lower the contact frame 11. The contact frame 11 supports one end of the bearing plate 9 through the contact wheel 12, thereby pushing or relying on gravity to fall naturally, causing the bearing plate 9 to rotate and be in a flat state, adapting to the tilt changes of the equipment, and allowing the worker to work stably.
[0032] The protective fence 13 provides protection by surrounding the upper part of the support plate 9, forming a protective structure to prevent workers from falling. Connected by the protective rotating seat 14, the placement frame 15 rotates, then the support rod 16 is rotated and unfolded, bringing it into contact with the protective fence 13 to form a support structure. The support placement frame 15 is in a horizontal state, providing a placement structure for welding tools, raw materials, etc., making them easy for workers to access and place, facilitating construction. The rotating groove 17 provides a rotation structure; when the placement frame 15 is not in use, the support rod 16 can be rotated to release the support. When the support rod 16 is unfolded, the limiting block 18 provides restraint, limiting the rotation range of the support rod 16 and ensuring a stable fit between the support rod 16 and the protective fence 13. The level 27 provides monitoring capability, displaying the balance status of the support plate 9, allowing workers to determine adjustment needs.
[0033] The access door 19 provides a structure that facilitates workers' access to and from the equipment. When the access door 19 is closed, rotating the fixing frame 20 causes a portion of the fixing frame 20 to engage with the protective fence 13, thus securing the access door 19. The support plate 9 has a climbing ladder 21 at one end of the access door 19 for workers to climb up and down, facilitating their work.
[0034] The lower end of the bearing plate 9 is provided with a mating groove 24. The mating groove 24 provides a structure that can cooperate with the contact frame 11 and the contact wheel 12, so that the contact frame 11 supports one end of the bearing plate 9 through the contact wheel 12, thereby pushing or relying on gravity to fall naturally, causing the bearing plate 9 to rotate and be in a flat state, adapting to the tilt changes of the equipment, and making the workers' work stable.
[0035] The bottom of the support plate 7 is provided with a connecting groove 22 that slides in conjunction with the sliding block 23. Specifically, the connection groove 22 and the sliding block 23 provide a mating structure, allowing the sliding block 23 to move stably within the connecting groove 22, the support plate 7 to move smoothly, and the contact frame 11 to be connected to the support plate 7, with the support plate 7 driving the contact frame 11 to move smoothly.
[0036] Many specific details have been set forth in the foregoing description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed above.
[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
