Description

Technical Field

[0001] The utility model relates to the technical field of transmission and transformation iron towers, and particularly relates to a double-wire submerged arc welding for transmission and transformation iron towers. Background Technique

[0002] In the construction of transmission and transformation iron towers, metal components usually have a large thickness, so a high-strength submerged arc welding process is required. Submerged arc welding covers a layer of flux in the weld area, melts the metal with the wire arc, and the flux melts under the arc to form a protective layer, which can effectively reduce welding spatter and achieve automatic welding of continuous long welds.

[0003] However, current submerged arc welding machines usually require manual follow-up operation. During the welding process, the flux hopper needs to be manually filled with flux, which is likely to cause uneven flux supply, thereby affecting the welding quality. In addition, the manual feeding method increases the risk of operators being exposed to welding fumes and high-temperature environments, posing certain safety hazards. The weld quality is unstable, and welding defects are likely to occur during long-term and large-scale construction.

[0004] Therefore, a double-wire submerged arc welding for transmission and transformation iron towers is needed to solve the problem of uneven flux supply. Content of the Utility Model

[0005] The purpose of the utility model is to provide a double-wire submerged arc welding for transmission and transformation iron towers to solve the problem of uneven flux supply mentioned in the above background technique.

The movable seat is movably assembled at the top of the traveling trolley. A platform is fixedly connected to the top of the movable seat. A hopper frame is fixedly connected to the left side of the top of the platform. A flux hopper is installed at the hopper frame. A flux nozzle is installed at the bottom of the flux hopper. A motor seat is fixedly connected to the left side of the flux hopper. A feeding motor is fixedly connected to the top of the motor seat. A dial is fixedly connected to the output shaft of the feeding motor. A fixing plate is fixedly connected inside the flux hopper. A rotating plate is rotatably connected to the bottom of the fixing plate. Material grooves are formed in both the fixing plate and the rotating plate.

[0007] Preferably, multiple groups of dial rods are annularly distributed on the edge of the dial. The dial drives the rotating plate to rotate through the dial rods. A wall groove for the rotation of the dial is formed on the left side of the flux hopper.

[0008] Preferably, the cross-section of the flux hopper is trapezoidal in an inverted shape. Guide beads are rollingly connected between the outer wall of the rotating plate and the inner wall of the flux hopper.

[0009] Preferably, a steering motor is fixedly connected to the middle position at the bottom of the traveling trolley. The steering motor is fixedly connected to the movable seat.

[0010] Preferably, the interior of the traveling trolley is hollow, and the platform above the traveling trolley can rotate within a range of 0-90° in the horizontal direction.

[0011] Preferably, a telescopic tube is fixedly connected to the right side of the bottom end of the walking trolley, a suction nozzle is installed at the bottom end of the telescopic tube, a suction pipe is fixedly connected to the top end of the telescopic tube, a suction pump is installed at the suction pipe, a recycling box is fixedly connected to the right side of the bottom end of the platform, and the suction pipe is connected to the recycling box.

[0012] Preferably, two groups of welding wire reels are arranged on the right side of the top of the platform, two groups of electric welder mounting frames are arranged on the left side of the welding wire reel, electric welders are installed on the electric welder mounting frames, two groups of wire feeding wheels are arranged under each group of electric welders, welding wire nozzles are arranged at the bottom of the electric welders, and wire guide motors are arranged on the right side of the electric welders.

[0013] Preferably, a controller is provided on the right side of the top of the platform, and walking wheels are respectively installed on both sides of the bottom of the walking trolley.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the double welding wire ambush welding of the power transmission and transformation iron tower not only realizes uniform and sufficient laying of flux, reduces the workload of manual cleaning of solid flux particles, but also realizes fixed depth of front welding and widening of rear welding, and the double welding wire improves welding quality;

[0015] (1) The ambush welding trolley is provided with a flux hopper, a fixed plate, a rotating plate, a dial, and a material trough. The ambush welding trolley adopts a front and rear double electric welder for welding. A fixed plate and a rotatable rotating plate are provided in the flux hopper. Solid flux particles are put into the flux hopper, and the feeding motor drives the dial to rotate. When the dial rotates slowly, the lever on its outer edge drives the rotating plate to rotate. Every time the rotating plate and the material trough at the fixed plate overlap, the solid flux particles fall to the flux nozzle and are laid to the front end of the weld, ensuring that the front end of the weld is always adequately covered with flux, providing good welding protection, solving the problem of uneven flux supply in traditional welding, and making the welding quality more stable and reliable;

[0016] (2) A recycling box, a suction nozzle, a pump, a steering motor, and a movable seat are provided. A recycling box is provided at the rear of the trolley. After ambush welding, excess solid flux particles are absorbed by the suction nozzle and pumped into the recycling box by the suction pump. Since the steering motor can drive the movable seat to rotate, the trolley can walk again from beginning to end after all the workpieces are welded. The solid flux particles can be sucked away by adjusting the angle of the movable seat. Whether during or after welding, the workload of manually cleaning the solid flux particles can be greatly reduced.

[0017] (3) By setting up an electric welding machine, the trolley uses double welding wires for submerged arc welding. There are two groups of electric welding machines. The application of the double-welding-wire structure not only improves the welding speed but also enhances the strength of the weld seam. The front welding determines the depth, and the rear welding widens, solving the problem that the single-welding-wire structure is prone to uneven weld seams. BRIEF DESCRIPTION OF THE DRAWINGS
