Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary technology, specifically to a lifting lug positioning auxiliary device. Background Technology

[0002] Sealed containers are widely used in daily life and production, especially for containers that are large in volume and weight. Lifting lugs are usually installed on the container body to facilitate transport. See [link / reference]. Figure 1 The schematic diagram of the container structure shows multiple lifting lugs 2 symmetrically arranged on the outside of the container body 1. Typically, the lifting lugs 2 are fixed to the body 1 by welding. In a sealed container structure, multiple lifting lugs 2 need to be welded to the outer shell. However, due to the roundness deviation of the container body 1, directly assembling and welding standard lifting lug 2 parts to the body body cannot guarantee the dimensions between any two lifting lugs 2, and the holes of the multiple lifting lugs 2 are not on the same plane. Due to welding process requirements, after the lifting lugs 2 are cut, to ensure the strength of the weld, the arc section of the welding point between the lifting lug 2 and the body 1 needs to be beveled with a K-type bevel. Currently, manual positioning is mostly used for welding operations, which cannot guarantee that the lifting lugs 2 are on the same positioning surface. This results in inconsistent or non-uniform shapes of the lifting lugs 2 after welding. The assembly and positioning of the lifting lugs 2 and the body 1 cannot guarantee the dimensional accuracy of the finished product, and manual positioning has low accuracy and is time-consuming and labor-intensive.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: It includes a base and multiple support plates fixed to the base. The multiple support plates are spaced apart along a first direction. Each support plate has a groove, and the grooves of the multiple support plates are coaxially arranged. The groove is used to accommodate the cylindrical body of a container, and the shape of the groove is adapted to the outer shape of the cylindrical body of the container. Corner plates are symmetrically arranged on both sides of the support plates along a second direction. Each corner plate has a positioning surface, which is used to support positioning lugs. The positioning surfaces of the multiple corner plates are on the same plane. The base has a support surface, and the positioning surface of the corner plate is parallel to the support surface of the base.

[0005] Furthermore, two support plates are arranged opposite each other on the base along the first direction. The two support plates are respectively arranged close to the two sides of the base along the first direction. Two corner plates are symmetrically arranged on each of the two support plates along the second direction. The first direction and the second direction are both horizontal and vertical.

[0006] Furthermore, the corner plate includes a first plate and a second plate connected in an L-shape. Both the first plate and the second plate are fixedly connected to the support plate. The upper surface of the second plate forms the positioning surface. A groove is formed between the first plate and the second plate. The grooves of the two corner plates on each support plate are symmetrically arranged opposite each other.

[0007] Furthermore, the corner plate is disposed near the upper end of the support plate, and the positioning surface of the corner plate is higher than the groove of the support plate.

[0008] Furthermore, the upper end of the support plate has extensions on both sides, and there is a notch between the extension and the plate body of the support plate.

[0011] Furthermore, reinforcing plates are spaced apart between the spaced-apart support plates along the second direction, with both ends of the reinforcing plates fixed to the spaced-apart support plates and the bottom end of the reinforcing plates fixed to the base.

[0012] Furthermore, the base includes a base plate, the upper surface of which forms the support surface of the base, and level adjusters are evenly arranged at the four corners of the base plate.

[0013] Furthermore, a level is provided on the upper surface of the base plate.

[0014] Compared with the prior art, this utility model has multiple support plates on the base, each with a groove that matches the shape of the container's cylinder. The grooves of the multiple support plates work together to support and position the cylinder, ensuring reliable and stable support and positioning. Additionally, corner plates are provided on both sides of the support plates, each with a positioning surface. The positioning surfaces of multiple corner plates are on the same plane and parallel to the support surface of the base. Therefore, after the container is supported on the support plates and the base is leveled, the multiple corner plates are also leveled accordingly. The corner plates are used to position and weld the lifting lugs, achieving precise positioning of the multiple lifting lugs, ensuring welding accuracy. The structure is simple, low-cost, efficient, and provides fast and reliable positioning, saving time and effort. Attached Figure Description

[0018] The present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] This utility model provides a lifting lug positioning auxiliary device, which can reliably position the container body 1 and the lifting lug 2, thereby ensuring the container welding, and especially facilitating the welding of the lifting lug 2. See details below. Figure 2 It includes a base 3 and multiple support plates 4 fixed to the base 3. The multiple support plates 4 are spaced apart along a first direction. Each support plate 4 has a groove 41. The grooves 41 of the multiple support plates 4 are coaxially arranged. The grooves 41 are used to accommodate the cylindrical body 1 of the container. The shape of the grooves 41 is adapted to the outer shape of the cylindrical body 1 of the container. Angle plates 5 are symmetrically arranged on both sides of the support plates 4 along a second direction. The angle plates 5 have positioning surfaces. The positioning surfaces are used to support the positioning lugs 2. The positioning surfaces of the multiple angle plates 5 are on the same plane. The base 3 has a support surface. The positioning surfaces of the angle plates 5 are parallel to the support surface of the base 3.

[0020] This utility model features multiple support plates 4 spaced apart on the base 3. Each support plate 4 has a groove 41 that matches the shape of the container's cylindrical body 1. The grooves 41 of the multiple support plates 4 work together to support and position the cylindrical body 1, ensuring reliable and stable support and positioning. Additionally, corner plates 5 are provided on both sides of the support plates 4. Each corner plate 5 has a positioning surface, and the positioning surfaces of the multiple corner plates 5 are on the same plane and parallel to the support surface of the base 3. Therefore, after the container is supported on the support plates 4 and the base 3 is leveled, the multiple corner plates 5 are also leveled accordingly. The corner plates 5 are used to position and support the lifting lugs 2 for welding, achieving precise positioning of the multiple lifting lugs 2, ensuring welding accuracy, and providing a simple, low-cost, efficient, and fast-reliable positioning solution that saves time and effort.

[0021] Specifically, in this embodiment of the invention, two support plates 4 are arranged opposite each other on the base 3 along a first direction. The two support plates 4 are respectively arranged close to both sides of the base 3 along the first direction. Two corner plates 5 are symmetrically arranged on each of the two support plates 4 along a second direction. It should be noted that both the first and second directions are horizontal and perpendicular. In other embodiments of the invention, three or four support plates 4 may be provided on the base 3, preferably to provide sufficient support and load-bearing capacity. The specific arrangement should consider the mass and volume of the container's cylinder 1 to maximize stability and improve safe load-bearing capacity. Furthermore, the number of corner plates 5 on each support plate 4 is not limited to two; it is selected based on the welding quantity and process requirements of the lifting lugs 2.

[0022] Specifically, the corner plate 5 includes a first plate and a second plate connected in an L-shape. Both the first and second plates are fixedly connected to the support plate 4. The upper surface of the second plate forms a positioning surface, and a groove is formed between the first and second plates. The grooves of the two symmetrical corner plates 5 on each support plate 4 are arranged opposite each other. The L-shaped corner plates 5 form a positioning support structure for the lifting lug 2, which is stable and simple. The positioning surface formed by the upper surface of the second plate provides support and positioning, thereby facilitating the welding of the lifting lug 2.

[0023] In this embodiment of the invention, the corner plate 5 is positioned near the upper end of the support plate 4, and the positioning surface of the corner plate 5 is higher than the groove 41 of the support plate 4. Because the welding position of the lifting lug 2 is slightly higher on the circumference of the cylinder 1 in this embodiment, the corner plate 5 is positioned near the upper end of the support plate 4, and the positioning surface of the corner plate 5 is higher than the groove 41 of the support plate 4. This ensures that the cylinder 1 is reliably and stably positioned within the lower groove 41, and the lifting lug 2 can be stably and accurately positioned on the positioning surface of the upper corner plate 5. Of course, in other embodiments of this invention, the installation position of the corner plate 5 can be adjusted as needed according to specific process requirements; therefore, the specific position of the corner plate 5 is not specifically limited here.

[0024] Preferably, the upper end of the support plate 4 has extensions 42 on both sides, and there is a notch 43 between the extensions 42 and the plate body of the support plate 4. The notch 43 has a first surface and a second surface connected in an L-shape. The first plate is fixed to the first surface, and the second plate is fixed to the second surface. That is, a notch is made on the inner side of the upper end of the groove 41 of the support plate 4, and the corner plate 5 is installed using the notch 43. The two vertical surfaces of the notch are used to fix the two plates of the corner plate, making the fixation more stable and reliable.

[0025] Preferably, the groove 41 is located in the middle of the support plate 4, and the groove 41 is open-ended, extending downwards from the upper end of the support plate 4, and is arc-shaped. The open shape of the groove 41 facilitates the hoisting of the cylinder 1 into this invention using lifting equipment, and positions and supports it within the groove 41, facilitating transportation. Simultaneously, the semi-circular shape of the groove conforms to the cylindrical shape of the cylinder 1, ensuring reliable contact between the bottom of the groove 41 and the outer wall of the cylinder 1, guaranteeing reliable positioning and preventing the cylinder 1 from wobbling and affecting welding quality. Of course, the shape of the groove 41 can also be square, semi-circular, polygonal, or other shapes, depending on the specific shape of the cylinder 1, reliably ensuring contact and fit between the two, and improving the load-bearing and positioning effect.

[0026] Preferably, reinforcing plates 6 are spaced apart between the spaced support plates 4 along the second direction. The two ends of the reinforcing plates 6 are fixed to the spaced support plates 4, and the bottom end of the reinforcing plates 6 is fixed to the base 3. The reinforcing plates 6 improve the rigidity between the support plates 4, preventing deformation of the support members 4, and also improve the load-bearing capacity of the support plates 4. In this invention, two reinforcing plates 6 are provided between the two support plates 4, and the two reinforcing plates 6 are located on the outer side of the groove 41. When the cylinder 1 is placed in the groove 41, it will not interfere with the welding operation of the cylinder 1. Of course, in other embodiments, to further improve the load-bearing capacity, multiple reinforcing plates 6 can be provided between the two support plates 4. The middle reinforcing plate 6 is lower in height, and there is sufficient gap between the reinforcing plate 6 and the cylinder 1 when the cylinder 1 is placed in the groove 41. Alternatively, the reinforcing plates 6 can also be provided with receiving grooves adapted to the shape of the cylinder 1, improving the load-bearing capacity without interfering with the welding operation of the cylinder 1.

[0027] Specifically, the base 3 includes a base plate, the upper surface of which forms the support surface of the base 3, and leveling adjusters 7 are evenly arranged at the four corners of the base plate. Using the base plate as the base 3 can reliably ensure flatness and facilitate leveling. The leveling adjusters 7 can be bolt-type, and the different heights of the base can be adjusted by rotating the bolts to achieve leveling. The leveling adjusters 7 can also be electric, etc., and no specific limitations are made here.

[0028] Preferably, a level 8 is provided on the upper surface of the base plate to facilitate workers to check the levelness. It is best to set it on both sides or four corners of the base plate to ensure that the base plate is completely level, thereby ensuring that the four corner plates 5 are completely level, so that the lifting lugs 2 can be accurately and reliably positioned and the welding quality can be guaranteed.

[0029] The base 3, support plate 4, corner plates 5, and reinforcing plate 6 of this utility model are all made of high-strength steel plates. The four L-shaped corner plates 5 are leveled by adjusting the base plate of the base 3 to ensure the flatness of the positioning surface of the corner plates 5 is within ±2mm. The spacing between the corner plates 5 across the container axis is fixed at 1500±1mm; the spacing along the container axis is floating. In use, the container is hoisted onto this utility model, and the container and base 3 are leveled using a lifting device. The corner plates 5 are also leveled accordingly. The flatness requirement is that the four lifting lugs 2 are on the same positioning surface, with a flatness requirement of ±2mm. The corner plates 5 are used to position and support the lifting lugs 2 for welding, eliminating the need for repeated measurement and adjustment processes, ensuring good accuracy. After the welding is firm, the fixture is removed and the welding is completed. This achieves precise positioning of multiple lifting lugs 2, ensures welding accuracy, has a simple structure, low cost, is simple and efficient, and provides fast and reliable positioning, saving time and effort.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
