Description

Technical Field

[0001] This utility model relates to the field of marine engineering construction, and in particular to a transport fixture for large-diameter steel pipes. Background Technology

[0002] Currently, in the field of marine engineering manufacturing, the transportation of large-diameter steel pipes usually involves pre-welding lifting lugs onto the steel pipes, then lifting and transporting them using a crane, and finally removing the lifting lugs for transportation. However, this transportation method is inefficient, requires repeated welding and removal of lifting lugs, and can damage the pipe wall, affecting the performance of large-diameter steel pipes. Utility Model Content

[0003] To overcome the above problems, this utility model provides a transport fixture for large-diameter steel pipes. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0004] A transport auxiliary tooling for large-diameter steel pipes includes a horizontal support plate, several vertical support legs at the bottom of the horizontal support plate, and a concave arc-shaped plate at the top of the horizontal support plate. The arc-shaped plate and the horizontal support plate are fixedly connected by a fixing plate. The radius of the arc-shaped plate is equal to the radius of the steel pipe, and the steel pipe is confined within the arc-shaped plate.

[0005] Furthermore, the central arc of the curved plate and the axis of the horizontal support plate are located in the same vertical plane; several first reinforcing ribs are provided between the fixed plate, the curved plate and the horizontal support plate to improve the connection strength of the curved plate.

[0006] Furthermore, the horizontal support plate has an "I" shaped cross section, with a second reinforcing rib between the upper and lower surfaces of the "I" shape to increase the load-bearing capacity of the horizontal support plate.

[0007] Furthermore, several hanging ears are provided on the horizontal support plate.

[0008] Furthermore, a base plate is fixed to the bottom of the vertical support leg to increase the contact area with the ground; and several third reinforcing ribs are fixed between the horizontal support plate and the base plate.

[0009] Furthermore, several auxiliary tooling fixtures are arranged in parallel, and the base plates of the auxiliary tooling fixtures are all fixedly connected by connecting plates to form a tooling assembly.

[0010] The beneficial effects of this utility model are:

[0011] This fixture includes a horizontal support plate with several vertical support legs at its bottom and a concave arc-shaped plate at its top. The arc-shaped plate and the horizontal support plate are fixedly connected by a fixing plate. The radius of the arc-shaped plate is equal to the radius of the steel pipe, and the steel pipe is confined within the arc-shaped plate. After the large-diameter steel pipe is fixed on the fixture, a forklift can be inserted between the vertical support legs to transport and transfer the steel pipe. Using this fixture, it is not necessary to weld lifting lugs onto the surface of the large-diameter steel pipe and then remove them, which can improve the transportation efficiency of large-diameter steel pipes. At the same time, using an arc-shaped plate that matches the diameter of the steel pipe can limit the position of the steel pipe while protecting the pipe wall, ensuring the quality of the steel pipe during transportation.

[0018] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the utility model "an auxiliary tooling for transporting large-diameter steel pipes" is provided in conjunction with the accompanying drawings.

[0019] See Figures 1-3In this embodiment, the auxiliary transport fixture includes a horizontal support plate 100. Two vertical support legs 101 are provided at both ends of the bottom of the horizontal support plate 100, forming a space between the vertical support legs 101 for a forklift to insert into. A concave arc-shaped plate 102 is provided at the top of the horizontal support plate 100. The arc-shaped plate 102 and the horizontal support plate 100 are welded and fixedly connected by a fixing plate 103. The radius of the arc-shaped plate 102 is equal to the radius of the large-diameter steel pipe, and the steel pipe is confined within the arc-shaped plate 102. In use, two or more auxiliary transport fixtures are placed vertically and parallel, and then the steel pipe is placed into the arc-shaped plate 102 for confinement. At the same time, ropes can be used to help to tie and fix it. Then, a forklift is used to lift and move the fixture and the steel pipe together. Using this tooling to assist in transporting large-diameter steel pipes eliminates the need to weld and cut lifting lugs onto the pipe, improving work efficiency. Furthermore, the arc-shaped plate 102 matches the pipe diameter, providing a semi-enclosed restraint on the pipe and offering protection during transport, thus ensuring the pipe's quality. It should be noted that in other embodiments, there may be two or more vertical support legs 101, as long as they can support the horizontal support plate 100 and allow sufficient space for a forklift to insert the workpiece.

[0020] See further Figure 1 In this embodiment, the central arc of the arc plate 102 and the axis of the horizontal support plate 100 are located in the same vertical plane. This is equivalent to the arc plate 102 lying on the horizontal support plate 100, and the pressure of the arc plate 102 is completely transferred to the horizontal support plate, ensuring the structural stability of the arc plate 102. At the same time, a number of first reinforcing ribs 104 are provided between the fixing plate 103, the arc plate 102 and the horizontal support plate 100 to improve the connection strength between the arc plate 102 and the horizontal support plate 100, and improve the stability and pressure bearing capacity of the arc plate 102.

[0021] More specifically, in this embodiment, the horizontal support plate 100 has an "I" shaped cross section, and a second reinforcing rib plate 105 is provided between the upper and lower surfaces of the "I" shaped cross section to increase the pressure bearing capacity of the horizontal support plate 100. At the same time, the arc-shaped plate 102 lies on the upper surface of the "I" shaped cross section. The design of the "I" shaped horizontal support plate 100 and the second reinforcing rib plate 105 ensure that the horizontal support plate 100 can withstand the pressure from the arc-shaped plate 102.

[0022] See further Figures 1-3 In this embodiment, the horizontal support plate 100 is provided with several hanging ears 106. The hanging ears 106 facilitate the fixing of the ropes for binding, and at the same time, the hanging ears 106 can also serve as lifting ears. The entire tooling is lifted and transported by a crane.

[0023] More specifically, in this embodiment, a base plate 107 is fixedly connected to the bottom of the vertical support leg 101. The base plate 107 is perpendicular to the vertical support leg 101 and its area is larger than the bottom area of ​​the vertical support leg 101, so as to increase the contact area between the vertical support leg 101 and the ground and improve the stability of the tooling when standing. In addition, several third reinforcing ribs 108 are fixedly arranged between the horizontal support plate 100 and the base plate 107 to improve the connection strength between the vertical support leg 101 and the base plate 107.

[0024] See further Figure 2 In this embodiment, several auxiliary tooling fixtures are arranged in parallel, and the base plates 107 of the auxiliary tooling fixtures are all fixedly connected by connecting plates 109 to form a tooling assembly. The overall structure of such a tooling assembly is more stable, and there will be no shaking or displacement after loading large-diameter steel pipes, which helps to assist in the transportation of steel pipes.
