[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] like Figures 1 to 5 As shown, this embodiment provides a pipe welding tool, which includes a support member 100 and a lining member 200, wherein the support member 100 includes at least three support rods 110, the support rods 110 include a fixed end 111 and a support end 112, the fixed ends 111 of all the support rods 110 are connected, and all the support rods 110 are radially dispersed; the length of the support rods 110 is adjustable, and the support ends 112 corresponding to all the support rods 110 are located in the same circumscribed circle, and the support ends 112 are used to support the pipe 1000 to be welded; the lining member 200 has an arc surface that can match the inner side surface of the pipe 1000 to be welded, and the arc surface covers the gap of the pipe 1000 to be welded in the circumferential direction of the pipe 1000 to be welded. After welding at the gap of the pipe 1000 to be welded, a weld 1200 is formed.

[0039] The pipe welding tool is provided with three support rods 110, and the mutually fixed support rods 110 are arranged radially, and all the support ends 112 are located in the same circumscribed circle, so that when splicing three arc plates 1100, the cylindricality of the entire pipe 1000 to be welded can be effectively guaranteed; when hoisting, the hoisting position can be set at the position where the support member 100 is installed, which can effectively avoid the problem of deformation during the hoisting process. In addition, the length-adjustable support rods 110 can adapt to pipes 1000 to be welded of different diameters, expanding the scope of application.

[0040] Due to the setting of the lining member 200, the lining member 200 is first matched with the inside of the pipe 1000 to be welded, and the gap of the pipe 1000 to be welded is covered by the arc surface, so that during welding, the problem of dents at the welding point can be avoided, thereby improving the yield rate.

[0041] In some embodiments, the support rod 110 includes a base member 120 and an extension member 130, the fixed end 111 is disposed at one end of the base member 120, the support end 112 is disposed at one end of the extension member 130, and the extension member 130 is connected to the base member 120. The separate structure allows the base member 120 to cooperate with the extension member 130, and when the extension member 130 is damaged, the extension member 130 can be replaced alone, thereby reducing the subsequent application cost.

[0042] In some embodiments, the base member 120 and the extension member 130 are welded. This connection method can improve the connection strength between the base member 120 and the extension member 130, which is conducive to ensuring the cylindricality of the pipe 1000 to be welded. When the base member 120 and the extension member 130 are welded, they partially overlap.

[0043] When in use, the support member 100 is located inside the pipe 1000 to be welded, and after welding is completed, the anchor chain locker or a part of the anchor chain locker is formed. The support member 100 is a distance away from the exit of the anchor chain locker, and it is difficult to take it out directly. Based on the above structure, the extension member 130 can be cut directly by cutting, so that the remaining support member 100 can be directly taken out. In some embodiments, only one extension member 130 can be cut. In some embodiments, both extension members 130 can be cut. In some embodiments, all three extension members 130 can be cut.

[0044] To facilitate the removal of the support member 100, in some embodiments, the support member 100 includes a gripping portion 140, which is used for a user to grip. The gripping portion 140 is an annular structure and is welded to the support member 100. The fixed end 111 is located at the center of the gripping portion 140, wherein a portion of the gripping portion 140 is connected between any two support rods 110.

[0045] The compressive strength of the base member 120 is greater than that of the extension member 130, and the length L1 of the base member 120 is greater than the length L2 of the extension member 130. This arrangement can improve the structural strength of the extension member 130 as much as possible, thereby improving the supporting strength of the support member 100. In addition, since the extension member 130 needs to be cut off, this arrangement also helps to reduce the consumption of finished products.

[0046] In some embodiments, the length of the extension member 130 is between 300 mm and 800 mm.

[0047] In some embodiments, the base member 120 is an I-beam or a channel steel. The extension member 130 is a steel bar. The above arrangement can use local materials, reduce costs, and effectively ensure the support strength of the support member 100.

[0048] There are at least three lining members 200, and at least three lining members 200 can cover at least three gaps of the pipes to be welded 1000. In other embodiments, the number of lining members 200 can be determined according to the specific number of pipes 1000 to be welded, that is, according to the number of welds 1200 between the pipes 1000 to be welded.

[0049] In some embodiments, the lining member 200 is fan-shaped as a whole. In other words, the cross section of the lining member 200 is fan-shaped, that is, the orthographic projection of the lining member 200 in the axial direction of the pipe to be welded 1000 is fan-shaped. In other embodiments, the orthographic projection of the lining member 200 in the axial direction of the pipe to be welded 1000 is a rectangular structure.

[0050] The lining member 200 is welded to the inner side wall of the pipe to be welded 1000. After the arc-shaped plates 1100 spliced ​​to form the pipe to be welded 1000 are welded, the lining member 200 can be directly cut off.

[0051] In some embodiments, the lining member 200 includes a working portion 210 and a buffer portion 220; the height of the working portion 210 is a first height H1, and the height of the buffer portion 220 is a second height H2, and the second height H2 is at least twice the first height H1. The height direction is the radial direction of the pipe 1000 to be welded. This arrangement allows the lining member 200 to be reused and improves its service life. The working portion 210 and the buffer portion 220 are integrally formed.

[0052] In order to prevent adhesion between the lining member 200 and the weld 1200 of the curved plate 1100 during welding of the curved plate 1100, the lining member 200 is provided with a plurality of avoidance grooves 230 at intervals around the circumference of the curved surface, the depth direction of the avoidance grooves 230 is from the working part 210 to the buffer part 220, and the opening of the avoidance grooves 230 is away from the buffer part 220. The depth of the avoidance grooves 230 is less than or equal to the height of the working part 210. The above arrangement reduces the contact area between the lining member 200 and the pipe 1000 to be welded, making it easier to cut the lining member 200 from the anchor chain locker; at the same time, the avoidance grooves 230 can accommodate part of the weld 1200.

[0053] In some embodiments, the thickness H3 of the lining member 200 is 5 mm to 20 mm. In some embodiments, the material of the arc plate 1100 can be used to reduce the manufacturing difficulty. The thickness direction is along the axial direction of the pipe 1000 to be welded.

[0054] When in use, three arc plates 1100 are spliced ​​to form a pipe 1000 to be welded, and then the support member 100 is placed in the pipe 1000 to be welded, and the position of each arc plate 1100 is adjusted to ensure the cylindricality of the pipe 1000 to be welded; the lining member 200 is welded between adjacent arc plates 1100 and covers the gap between the two arc plates 1100; two arc plates 1100 are welded on the outside; after the arc plates 1100 are welded, the lining member 200 is removed by cutting, and after the lining member 200 is removed, the pipe 1000 to be welded forms an anchor chain locker or a part of the anchor chain locker. After the anchor chain locker is transferred to the next station, the support member 100 is removed to achieve the recycling of the support member 100.

[0055] First, the size of the support member 100 is determined by measuring the anchor chain locker, and then the support member 100 of the corresponding size is prepared, and the anchor chain locker of the same structure is assisted by the support member 100.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
