[0003] In related technologies, multiple spaced roller frames are used to support the cold box module. The roller frames are arc-shaped to match the cold box module, and rollers are set at the arc-shaped support positions. The motor drives the rollers to rotate, which in turn drives the cylinder to be welded to rotate. However, during welding, the cold box tower body is prone to local deformation, which affects the welding effect.

[0027] During the installation of large equipment such as cold box towers, which consist of multiple cold box modules, the ends of different cold box modules need to be welded on-site. The cold box modules need to be rotated during welding to facilitate welding at each point and avoid the dangers of working at height. In related technologies, multiple spaced roller frames are used to support the cold box modules. The roller frames are arc-shaped to match the cold box modules, and rollers are set at the arc-shaped support positions. The motor drives the rollers to rotate, thereby driving the cylinder to be welded to rotate. However, during welding, the cold box tower is prone to local deformation, which affects the welding effect.

[0028] Based on this, this utility model proposes a welding position adjustment device 100 for a cold box module. Please refer to [link / reference]. Figures 1 to 3 In one embodiment of this utility model, multiple support ring assemblies and multiple support seats are provided. The multiple support ring assemblies are used to be fixedly sleeved on the outer side wall of the cold box module to form a cold box welding structure with the cold box module. The multiple support seats are disposed below the cold box welding structure and include two rollers arranged in the front-back direction. Each roller rotates about an axis extending in the left-right direction. Each roller is tangent to the cold box welding structure and is used to drive the cold box welding structure to rotate about the axis extending in the left-right direction.

[0029] In the technical solution of this utility model, the support ring assembly 1 is used to maintain the original shape of the cold box module and prevent deformation due to pressure or welding. The support base 2 is used to rotate the cold box module to adjust the welding position, making it easier for operators to perform welding.

[0030] It should be noted that "each of the rollers 21 is tangent to the cold box welding structure" means that the rollers 21 can be tangent to the outer wall of the support ring assembly 1 or to the outer wall of the cylinder 200 to be welded.

[0031] In one embodiment, the roller 21 is tangent to the outer wall of the cylinder 200 to be welded, which can maintain the original shape of the cold box module and prevent welding deformation.

[0032] Since the cylinder 200 to be welded has a certain weight and is driven to rotate by the rollers 21, the contact area is small, and it is prone to local deformation before welding, which affects the welding effect. In one embodiment, each of the rollers 21 is tangent to the outer wall of the support ring assembly 1. While adjusting the welding position, the pressure area between the cylinder 200 to be welded and the rollers 21 is increased, the pressure on the contact surface is reduced, thereby reducing the deformation of the cylinder 200 to be welded. In addition, the support ring assembly 1 can act as a clamp to prevent the cylinder 200 to be welded from deforming during welding.

[0033] In addition, the rollers 21 can be movably arranged in the front-back direction, and the distance between the two rollers 21 can be adjusted according to the size of the cylinder 200 to be welded. Furthermore, a flexible layer is provided on the surface of the rollers, and the flexible layer material is preferably polyurethane.

[0034] Furthermore, two rollers 21 arranged in the front-to-back direction constitute a roller 21 group, and the support base 2 can be provided with multiple roller 21 groups arranged in the left-to-right direction to enhance rotational stability.

[0035] In one embodiment of this utility model, the support ring assembly 1 includes a first fixing ring 11 and a second fixing ring 12. The first fixing ring 11 is tangent to the roller 21 and is used to fix it to the outer wall of the cylinder 200 to be welded. The second fixing ring 12 is disposed inside the first fixing ring 11 and abuts against the inner wall of the cylinder 200 to be welded, thereby radially supporting the cylinder 200 to be welded. With this arrangement, the first fixing ring 11 and the second fixing ring 12 are respectively disposed inside and outside the cylinder 200 to be welded, fixing the cylinder 200 from the outside to the inside and supporting it from the inside to the outside, greatly enhancing the deformation resistance of the cylinder 200 to be welded, effectively improving the stability during the welding process, and ensuring welding quality.

[0036] In one embodiment of this utility model, the second fixing ring 12 includes a fixing ring 121 and a protective layer; the fixing ring 121 is disposed inside the first fixing ring 11; the protective layer is disposed outside the fixing ring 121, and is used to abut against the cylinder 200 to be welded under the support of the fixing ring 121. The material of the protective layer includes an elastic material. Thus, the protective layer prevents the inside of the workpiece to be welded from being scratched by the fixing ring 121, while also enhancing the supporting effect of the fixing ring 121, ensuring that the cylinder 200 to be welded is subjected to uniform force during rotation, further improving welding accuracy and safety.

[0037] Among them, the elastic materials include natural rubber, silicone, etc., which have good elasticity and wear resistance, and can effectively buffer the friction between the fixing ring 121 and the cylinder 200 to be welded, thus extending the service life of the equipment.

[0038] In one embodiment of this utility model, the first fixing ring 11 includes a plurality of outer arc segments 113, which are circumferentially distributed along an axis extending in the left and right directions; the second fixing ring 12 includes a plurality of inner arc segments 122, which are circumferentially distributed along an axis extending in the left and right directions; the support structure further includes a plurality of magnetic absorbing components 3, which are circumferentially distributed along an axis extending in the left and right directions, and each magnetic absorbing component 3 includes a first magnetic absorbing part 31 and a second magnetic absorbing part 32; the first magnetic absorbing part 31 is disposed within the plurality of outer arc segments 113; the second magnetic absorbing part 32 is disposed within the plurality of inner arc segments 122, and magnetically engages with the first magnetic absorbing part 31, so that the support ring assembly 1 contracts inward and the inner ring assembly supports outward, so that the support ring assembly 1 is fixed to the outer side wall of the cylinder 200 to be welded, and the inner ring assembly abuts against the inner side wall of the cylinder 200 to be welded. Thus, with the cooperation of the magnetic suction component 3, the support ring component 1 can be quickly installed and disassembled, and the supporting force of the first fixing ring 11 and the stability of the second fixing ring 12 can be further improved, ensuring that the cylinder does not shift during the welding process, thereby improving the welding quality and efficiency, and further facilitating the removal of the second fixing ring 12 from the tower body after welding.

[0039] Furthermore, the first magnetic suction part 31 and the second magnetic suction part 32 can be detachably set with the outer arc segment 113 and the inner arc segment 122, respectively. In this way, when welding cylinders 200 of different sizes, only the corresponding outer arc segment 113 and inner arc segment 122 need to be replaced to adapt to cylinders of different diameters. The support structure can be flexibly adjusted to ensure a stable support effect under various working conditions. The position of the magnetic suction component 3 can be adjusted according to actual needs to ensure that the support ring component 1 fits tightly with the cylinder. This allows for flexible adaptation to various welding scenarios and improves the equipment's versatility and ease of operation.

[0040] In one embodiment of this utility model, the plurality of outer arc segments 113 and the plurality of inner arc segments 122 are staggered in their circumferential positions along the left-right extending axis. This staggered arrangement effectively avoids stress concentration caused by overlapping arc segments and makes the adsorption force distribution of the magnetic attraction component 3 more uniform, improving the fixing effect of the support ring component 1 on the cylinder. This ensures that the cylinder remains stable under various complex welding environments, thereby significantly improving welding quality and efficiency.

[0041] In one embodiment of this utility model, both the first magnetic attraction part 31 and the second magnetic attraction part 32 are configured as electromagnets. This allows the attraction force of the electromagnets to be adjusted according to the shape of the cylinder to be welded, ensuring minimal welding deformation and further improving welding accuracy and stability.

[0042] In one embodiment of this utility model, the first fixing ring 11 includes a reinforcing ring 111 and a friction ring 112. The reinforcing ring 111 is tangent to the roller 21 and is used to fit onto the cylinder 200 to be welded. The friction ring 112 is fixedly disposed inside the reinforcing ring 111 and is positioned between the reinforcing ring 111 and the cylinder 200 to be welded, thereby enhancing the friction between the reinforcing ring 111 and the cylinder 200 to be welded. Thus, by adding the friction ring 112, the slippage of the cylinder during welding is effectively prevented, further improving the stability and support of the fixing ring, ensuring a smooth welding process, and significantly improving welding quality and efficiency.

[0043] Furthermore, the coefficient of friction of the inner surface of the friction ring 112 is μ, where 0.45 ≤ μ ≤ 0.55.

[0044] Furthermore, the inner surface of the friction ring 112 is provided with anti-slip grooves.

[0045] In one embodiment of this utility model, the base includes a mounting part and a movable part; the mounting part is fixedly disposed below the cylinder 200 to be welded; the movable part is movably disposed in the mounting part along the vertical direction, and is used to mount the motor and the roller 21. Thus, the design of the movable part allows the mounting positions of the motor and roller 21 to be flexibly adjusted according to the height of the cylinder, making the connection between two adjacent cylinders 200 to be welded more precise and avoiding welding errors caused by height differences.

[0046] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
