During in-service maintenance, the branch pipe seat 27 and the elbow side branch pipe 29 are welded, and a weld seam 28 to be welded is formed between the branch pipe seat 27 and the elbow side branch pipe 29. If it is in a narrow space, manual welding operation is difficult to implement, welding quality is difficult to guarantee, and there are multiple repairs; the welding of the branch pipe seat 27 and the elbow side branch pipe 29 requires automatic welding.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] At least one embodiment of the present application provides a welding actuator fixing device, which is mainly used for reliable positioning and installation of the welding actuator during automatic welding of the small branch pipe seat 27 and the elbow side branch pipe 29. Figure 2 The welding actuator fixing device mainly includes a positioning pipe clamp 1, a fixing clamp block 2, a plurality of magnetic blocks 3, a plurality of connecting rods 4, a plurality of supporting rods 5, a position adjustment mechanism 6 and a supporting mechanism 7. The positioning pipe clamp 1, the fixing clamp block 2 and the supporting rod 5 are all installed on the same side of the supporting mechanism 7. The position adjustment mechanism 6 is installed on the other side of the supporting mechanism 7. The connecting rod 4 is connected between the magnetic block 3 and the supporting rod 5.

The positioning pipe clamp 1 is used for installation in conjunction with the branch pipe seat 27 in the welding actuator through the fixing clamp block 2. The position adjustment mechanism 6 is used for fixed installation and position adjustment of the welding actuator.

[0030] It should be noted that the positioning pipe clamp 1 can be serialized and can be replaced according to the size of the branch pipe seat 27. The material of the mother pipe 26 can be carbon steel.

[0031] According to the technical solution provided in the embodiment of the present application, by setting a positioning pipe clamp 1 for installation in conjunction with the branch pipe seat 27 in the welding actuator through the fixing clamp block 2, the concentric positioning of the entire welding actuator fixture and the weld to be welded is achieved, with a simple structure and convenient operation. The position adjustment of the magnetic block 3 is achieved through multiple connecting rods 4 and multiple support rods 5. The serialized positioning pipe clamps and the position-adjustable magnetic blocks can adapt to different pipe outer diameters and spatial environments on site, and have strong applicability. The entire welding actuator fixture is fixed to the mother pipe 26 through the magnetic block 3, and the magnetic force can be turned on and off by the knob on the magnetic block 3, so that the overall position can be adjusted. The embodiment of the present application realizes the installation of the welding actuator fixture near the pipeline through magnetic adsorption combined with a position-adjustable locking structure, ensures the precise positioning of the welding actuator for the weld to be welded, solves the problem that the welding actuator cannot be installed and fixed on both sides of the weld to be welded due to the short branch pipe seat 27 and the elbow side branch pipe 29 being not parallel to the weld 28 to be welded, and improves the welding quality.

[0032] In at least one embodiment of the present application, the number of the multiple magnetic blocks 3 , the multiple connecting rods 4 , and the multiple supporting rods 5 is 4 each, and they are evenly distributed on the supporting mechanism 7 .

[0033] It should be noted that the number of the plurality of magnetic blocks 3, the number of the plurality of connecting rods 4 and the number of the plurality of supporting rods 5 are equal. The number of the plurality of magnetic blocks 3, the plurality of connecting rods 4 and the plurality of supporting rods 5 can be limited according to actual conditions, for example, it can also be 3, 5 or more.

[0034] The support mechanism 7 may be rectangular, circular or X-shaped. Taking the X-shaped support mechanism 7 as an example, in at least one embodiment of the present application, the support mechanism 7 includes a middle portion and a plurality of extension portions extending from the middle portion. The plurality of extension portions are respectively provided with a plurality of through holes, each of which is used to fix and install the support rod 5. The positioning pipe clamp 1 is located on one side of the middle portion, and the position adjustment mechanism 6 is located on the other side of the middle portion.

[0035] In at least one embodiment of the present application, reference FIG. 3A to FIG. 3CThe position adjustment mechanism 6 includes a welding actuator fixed platform 8, a connecting tube 9, a limit plate 10, a guide sleeve 11, a propulsion platform 12, a fixed block 13, a hand wheel 14, a screw nut 15, a screw 16, a sleeve 17, a first bearing 18 and a second bearing 19; the hand wheel 14 is connected to the screw 16 by screws, and a sleeve 17, a first bearing 18 and a second bearing 19 are installed between the fixed block 13 and the screw 16; the screw nut 15, the guide sleeve 11 and the connecting tube 9 are installed on the propulsion platform 12, the upper part of the screw 16 is connected to the limit plate 10 by screws, and the welding actuator fixed platform 8 is connected to one end of the connecting tube 9 by bolts. The screw 16 and the screw nut 15 are threadedly matched, and the relative movement of the screw 16 and the screw nut 15 is achieved by adjusting the hand wheel 14, and finally the welding actuator fixed platform 8 is moved up and down through the force transmission between the propulsion platform 12 and the connecting tube 9.

[0036] It should be noted that the position adjustment mechanism 6 may also include accessories such as bolts, screws, etc. The components may be connected and installed by bolts or jackscrews. For example, the screw nut 15, the guide sleeve 11 and the connecting tube 9 may be installed on the propulsion platform 12 by bolts or screws.

The installation of the position adjustment mechanism 6 and the support mechanism 7 is achieved by the bolt connection between the fixing block 13 and the support plate 22. Through the guiding effect of the guide sleeve 11 on the position adjustment mechanism 6 and the guide rod 21 on the support mechanism 7, the welding actuator fixed platform 8 is smoothly pushed forward and moved downward. In this way, the jamming phenomenon is avoided.

[0040] It should be noted that the supporting mechanism may also include accessories such as bolts.
