Description

Technical Field

[0001] The utility model relates to the technical field of lifting lug welding, in particular to a lifting lug assembly welding tool. Background Art

[0002] Lifting lugs are typically metal devices attached to equipment, containers, pipes, or other heavy objects for lifting, handling, or suspending them. In many engineering applications, pipes need to be lifted, moved, or installed in specific locations. Lifting lugs connect pipes to lifting equipment, such as crane hooks. These lugs are welded to the pipes, effectively transmitting the lifting force to the pipes.

[0003] In the traditional pipe and lug welding tooling process, the pipe is usually fixed. When welding is required at different circumferential positions of the pipe, the welding equipment may find it difficult to reach the appropriate welding position. When the lug needs to be welded at the bottom or lower side of the pipe, given the limited operating space of the welding equipment, it may be necessary to use complex auxiliary tooling or adopt a special operating posture to carry out the welding operation, which will undoubtedly increase the difficulty coefficient of welding and increase the welding cost. Therefore, the present application provides a lug assembly welding tool to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a lifting lug assembly welding tool to solve the problem that it is difficult to perform full-circle welding on the pipeline during the existing pipeline and lifting lug welding tool process.

[0005] In order to solve the above technical problems, the present utility model provides the following technical solutions.

[0006] A lifting lug welding tool comprises: a working plate; three supporting assemblies, which are arranged on the working plate, and the three supporting assemblies are located on the same central horizontal line; a pipe, which is arranged on the supporting assemblies; two groups of adjustment assemblies, which are respectively arranged on both sides of the pipe; a lifting lug body, which is arranged on the adjustment assemblies; and the three supporting assemblies are located between the two groups of adjustment assemblies; the number of adjustment assemblies in each group is two, and they are symmetrically arranged along the longitudinal center line of the working plate, and the number of slide slots corresponds to the number of adjustment assemblies.

[0007] The support assembly includes: a support column, which is arranged on the working plate, and the top of the support column is arc-shaped; a groove, which is arranged on the support column; and a plurality of rotating rods, which are rotatably arranged in the groove.

[0008] It also includes: a conveyor belt, which is sleeved on the rotating rod; a motor, which is arranged on the top of the supporting column; one end of one of the rotating rods passes through the supporting column and is connected to the output end of the motor.

[0009] The adjustment assembly includes: a mounting plate, which is arranged at one end of the pipe; a sliding block, one end of which is slidably arranged in the mounting plate, and the sliding block is T-shaped; two screws, which are arranged at the other end of the sliding block; the lifting ear body is in sliding contact with the mounting plate, and the lifting ear body is provided with two through holes, and the size of the screw matches the size of the through holes.

[0010] It also includes: a screw rod, one end of which is rotatably arranged on the mounting plate, and the other end passes through the mounting plate; one end of the screw rod is threadedly arranged with the sliding block.

[0011] It also includes: a connecting column, one end of which is arranged on the bottom of the mounting plate; and a sliding groove, which is arranged on the working plate.

[0012] It also includes: an electric slide rail, which is arranged in the slide groove; and the other end of the connecting column is connected to the electric slide rail.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] In the above scheme, by setting up a support assembly, the support column provides vertical support force for the pipeline, and the motor drives the rotating rod to rotate, so that the conveyor belt rotates, thereby driving the pipeline to rotate. According to actual needs, the part of the pipeline that needs to be welded can be accurately adjusted to the appropriate position to ensure that the welding equipment is easy to operate.

DETAILED DESCRIPTION

[0025] The following describes in detail a lifting eye assembly welding tool provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, to provide a more detailed description, the following embodiments are best and preferred embodiments, and those skilled in the art may also adopt other alternatives for implementing certain known technologies. Furthermore, the accompanying drawings are only for the purpose of describing the embodiments in more detail and are not intended to limit the present invention.

[0026] like Figure 1 - Figure 6 As shown, an embodiment of the present invention provides a lifting lug welding fixture, comprising: a work plate 1; three support assemblies 3, arranged on the work plate 1, and the three support assemblies 3 are located on the same central horizontal line; a pipe 2, arranged on the support assembly 3; two sets of adjustment assemblies 4, respectively arranged on both sides of the pipe 2; a lifting lug body 8, arranged on the adjustment assembly 4; and the three support assemblies 3 are located between the two sets of adjustment assemblies 4. By arranging the three support assemblies 3 on the same central horizontal line to support the pipe 2, this multi-point support method increases the horizontal stability of the pipe 2. Compared with single-point support, three-point support can better resist external interference forces, such as slight vibrations that may occur during welding or the influence of ambient airflow, ensuring that the pipe 2 maintains a fixed position and posture during welding.

[0027] The support assembly 3 includes: a support column 31, which is arranged on the working plate 1, and the top of the support column 31 is arc-shaped; a groove 32, which is arranged on the support column 31; and a plurality of rotating rods 35, which are rotatably arranged in the groove 32. By setting the number of rotating rods 35 to be at least three or more, a stable triangular structure can be formed by setting three rotating rods 35, thereby effectively driving the normal rotation of the conveyor belt 33. The three fulcrums can provide support in different directions, which helps to reduce the swing or tilt caused by the deviation of the center of gravity, thereby ensuring the stability of the pipeline 2 during the rotation process; in contrast, if only two rotating rods 35 are provided, then they can only provide support in a straight line. When the pipeline 2 is affected by external forces or due to its own gravity, it may tend to tilt around the straight line formed by the two rotating rods 35, so that the stable rotation of the pipeline 2 cannot be guaranteed; and if only one rotating rod 35 is provided, then The system will completely lack lateral stability, and a single support point is not enough to resist any lateral force or vibration. Such a design makes it almost impossible for the pipe 2 to maintain a fixed position during the welding process; the motor 34 drives the rotating rod 35 to rotate, so that the rotating rod 35 rotates, thereby rotating the conveyor belt 33, and finally driving the pipe 2 to rotate; by setting the support column 31, the top of the support column 31 is designed to be arc-shaped, which not only fits better with the curved surface of the pipe 2, ensuring the precise alignment of the pipe 2 on the support column 31, thereby facilitating the accuracy of the position during welding, but also enhances the stability of the pipe 2 on the support column 31, and reduces the deviation caused by the weight of the pipe 2 itself or external factors.

[0028] It also includes: a conveyor belt 33, which is sleeved on a rotating rod 35; a motor 34, which is arranged on the top of the support column 31; one end of one of the rotating rods 35 passes through the support column 31 and is connected to the output end of the motor 34.

[0029] By setting up a motor 34, the motor 34 provides a power source for the rotating rod 35, thereby rotating the pipeline 2. The motor 34 can be connected to the rotating rod 35 located at the center, and the motor 34 can also be connected to the rotating rods 35 located on both sides. The specific design is based on actual needs.

[0030] The adjustment assembly 4 includes: a mounting plate 41, which is arranged at one end of the pipe 2; a sliding block 43, one end of which is slidably arranged in the mounting plate 41, and the sliding block 43 is T-shaped; two screws 42, which are arranged at the other end of the sliding block 43; the lifting ear body 8 is in sliding contact with the mounting plate 41, and the lifting ear body 8 is provided with two through holes, and the size of the screw 42 matches the size of the through holes.

[0031] By setting up the mounting plate 41, a stable platform is provided for the sliding block 43, the screw 42 and the connection with the ear body 8; by setting up the sliding block 43, the through hole of the ear body 8 is passed through the screw 42, and then the ear body 8 is fixed by a nut to prevent displacement.

[0032] The screw rod 44 further includes a screw rod 44, one end of which is rotatably mounted on the mounting plate 41 and the other end of which passes through the mounting plate 41; one end of the screw rod 44 is threadedly mounted on the sliding block 43. The screw rod 44 can be provided with a damping knob on the end of the screw rod 44 that passes through the mounting plate 41, thereby making the rotation of the screw rod 44 more precise and preventing excessive position adjustment of the lifting lug body 8 due to excessive rotation or loosening of the screw rod 44.

[0033] The device further comprises a connecting post 7, one end of which is disposed at the bottom of the mounting plate 41, and a slide 6 disposed on the working plate 1. The connecting post 7 supports the adjustment assembly 4, and an electric telescopic rod or a cylinder can be disposed within the connecting post 7 to raise and lower the adjustment assembly 4 and adjust its height. The specific design is based on actual needs.

[0034] The electric slide 5 is provided in the slide groove 6, and the other end of the connecting post 7 is connected to the electric slide 5. The electric slide 5 and the connecting post 7 provide a horizontal driving force, thereby driving the adjustment assembly 4 and the lifting ear body 8 to move horizontally.

[0035] The technical solution provided by the present invention is to pass the screw 42 through the through hole of the lifting ear body 8, and then fix it with a nut, place the pipe 2 on the support column 31, use the external controller to start the electric slide 5 to move, drive the connecting column 7 to move, so that the mounting plate 41 contacts the pipe 2, rotate the screw 44, drive the sliding block 43 to move, so that the lifting ear body 8 moves until it contacts the pipe 2, and weld the pipe 2 and the lifting ear body 8. After completion, remove the nut, move the electric slide 5, so that the connecting column 7 moves, and separate the adjustment component 4 from the pipe 2. Use the external controller to start the motor 34 to drive the rotating rod 35 to rotate, so that the conveyor belt 33 rotates, and the pipe 2 is rotated to adjust its position, and repeat the above operation to weld the new lifting ear body 8 and the pipe 2.

[0036] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
