Embodiment Construction
[0044] like figure 2 and image 3 As shown, the special equipment for vertical gas-electric vertical welding includes a plate-shaped frame body 1, and the plate-shaped frame body 1 is divided into the straight side side (left side in the figure) behind the back of the plate to be welded in the use stage and the one located on the back side of the plate to be welded. Two parts on the profiled side (right side in the picture) of the front front. Wherein the support body upper part of straight side side perforates wheel axle 2 to set positioning wheel 3 after; Correspondingly, the back slider 4 is provided with a hole structure for hooking with the hook structure of the plate-shaped frame body.
[0045]The front end faces of the positioning wheel 3 and the back slider 4 are in a plane, and are used to fit the back side of the steel plate 10 to be welded; There may be a slight deviation on the surface, and a slight displacement of the hanging arm, so as to ensure a tight fit b...

Abstract
The invention discloses a special vertical electro-gas welding device, which comprises a platy frame body (1), wherein the platy frame body (1) is divided into a straight side which is positioned on the back surface of a steel plate (10) to be welded in the application process and a specially-shaped side in the front of the steel plate (10); a wheel shaft (2) runs through the upper part of the frame body on the straight side and is provided with a positioning wheel (3); the lower part of the frame body on the straight side is of a strip shape, and the lower end part of a strip-shaped plate (20) is provided with a back slide block (4) through a hook structure; the positioning wheel and the front end surface of the back slide block stay in the same plane and used for bonding the back parts of the steel plates; and the position on the frame body of the specially-shaped side relatively between the positioning wheel and the back slide block is provided with a guide jacking mechanism for supporting two side steel plates to be welded. The device is specially used for the vertical electro-gas welding, the back slide block and the positioning wheel on the back surface of the steel plate to be welded and the guide jacking wheel on the front surface collectively clamp the steel plate to be welded, a third-generation (3G)-electro-gas welding (EGW) back slide block device and the back slide block move along a weld seam so as to track the weld seam, and the back slide block is guaranteed to be closely bonded with the steel plate in the welding process.
Description
technical field [0001] The invention relates to electric welding equipment, more specifically, to equipment for realizing vertical gas-electric vertical welding. Background technique [0002] Vertical gas-electric vertical welding is a high-efficiency welding method that pastes a ceramic liner on the back of the base metal groove and welds on the front of the groove to realize the front and back of the weld at one time. widely used. [0003] figure 1 It is the schematic diagram of vertical gas-electric vertical welding. Among them, a ceramic liner 111 is placed on the back of the base metal 112 to be welded, a slider 113 is pressed on the front of the base metal 112, and a welding torch 114 is sent to the weld. The figure shows slag 115, arc 116, and molten metal 117 , solidified weld seam 118, and shielding gas delivery port 119, cooling water input port 120, and cooling water discharge port 121. [0004] In the prior art, the ceramic liner 111 selected for the above-me...
