Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a welding equipment for laying joints of deck sheets. Background Technique

[0002] Electric welding refers to a welding method that uses electric energy to heat or pressurize, or both, with or without filler materials, so that the welded parts reach atomic bonding. During the erection of the offshore oil well platform for the external expansion of the single platform, it is necessary to fix adjacent deck sheets by welding.

[0003] The existing Chinese utility model patent with the reference publication number of CN211219284U discloses a joint welding equipment, including a load-bearing bracket, and also includes a clamping mechanism. A load-bearing welding table is installed at the top of the load-bearing bracket, and a welding machine frame is installed at the rear surface position of the top of the load-bearing welding table. A welding head is slidably connected to the welding machine frame. Two groups of clamping mechanisms are installed at the position directly below the welding head on the top of the load-bearing welding table. The clamping mechanism includes a limiting rod slidably installed on the load-bearing welding table. The bottom of the limiting rod penetrates the top arm of the load-bearing welding table and is fixedly connected to a load-bearing sliding plate; through the clamping mechanism designed and installed on the top of the load-bearing welding table, the clamping and alignment of the steel to be processed are realized, greatly increasing the accuracy of the butt joint of the steel to be processed. And through the load-bearing rollers slidably installed outside the limiting rod, the auxiliary movement when the clamping mechanism is separated from the steel to be processed is greatly facilitated, and at the same time, the use cost is greatly reduced.

[0004] The welding torch of the existing welding equipment is generally fixed above the torch rack, and the welding torch moves at the joint for welding. Since the position of the welding torch is fixed, this method cannot control the position of the welding point, and the fluidity of the molten metal is poor, which may cause defects such as pores and slag inclusions in the weld seam. At the same time, since the relative position between adjacent deck sheets cannot be fixed during welding, it may cause too large a gap at the joint, affecting the welding quality.

[0015] Compared with the prior art, the present utility model provides a deck sheet laying joint welding device, which has the following beneficial effects:

[0016] 1. Through the setting of the bottom plate in the present utility model, the limiting magnets are symmetrically installed at the front and rear ends of the bottom plate with the center of the bottom plate as a reference. During welding, the center of the bottom plate is located directly above the joint of the deck sheets, and the limiting magnets will adsorb the two side deck sheets. Since the position of the limiting magnets is restricted by the bottom plate, this method can keep the relative positions of the deck sheets fixed during the welding process, avoiding the joint width between the deck sheets from being too large due to the movement of the deck sheets during welding, which affects the welding operation.

[0017] 2. Through the setting of the connecting frame in the present utility model, the connecting frame is rotatably connected to the receiving plate through a damping bearing, the welding torch is fixed at the front end of the connecting frame, the distance between the bottom end of the welding torch and the bottom surface of the bottom plate is fixed.

By adjusting the current direction, the magnetic poles of the two side electromagnets are opposite, the permanent magnet will have the same magnetic pole as one side electromagnet and the opposite magnetic pole to the other side electromagnet. The connecting frame will be driven by the permanent magnet to rotate with the center of the damping bearing as a reference to change the position of the welding torch. By adjusting the current direction to exchange the magnetic poles of the left and right side electromagnets, the permanent magnet drives the connecting frame to rotate clockwise and counterclockwise alternately, so that the welding torch moves left and right at the joint. And the worm gear meshes with the worm. When the driving motor drives the worm gear to drive the worm to rotate through the driving shaft, the worm will drive the transmission shaft to rotate. Since the gear meshes with the rack, the transmission shaft will drive the gear to rotate when rotating, and the position of the connecting plate will move forward with the rotation of the gear, so that the welding torch moves forward in a "Z" shape along the joint. This method can improve the fluidity of the metal melted by the welding torch and avoid defects such as pores and slag inclusions in the weld seam. Description of the Drawings

[0035] The limiting frame 211 is symmetrically installed above the receiving plate 26 with the center of the receiving plate 26 as the reference. The permanent magnet 210 is located between the limiting frames 211. The electromagnet 212 is symmetrically installed inside the limiting frames 211 on the left and right sides above the receiving plate 26 with the center of the receiving plate 26 as the reference and is mirror-symmetrical left and right.

[0036] Specifically, the support plate 2 can support the support frame 21. The support frame 21 can facilitate the fixed connection between the driving motor 22 and the support plate 2.

This method can improve the fluidity of the metal melted by the welding torch 29 and avoid defects such as pores and slag inclusions in the weld seam.
