Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to an automatic welding device for connection nodes of power transmission towers. Background Technology

[0002] To prevent pedestrians from accidentally touching cables, metal towers are often built to support the cables at the top, allowing high-voltage current to travel through the air and greatly reducing the probability of electric shock accidents. To facilitate transportation or assembly of the towers, welding equipment is often used to install components from different parts together.

[0003] Welding equipment is often equipped with matching fixtures to limit and reinforce the metal rods extending from both sides, preventing the tower components from shaking during welding. However, it lacks a pushing mechanism, requiring workers to assist in picking up parts. It cannot automatically discharge rods and other objects, and the welding position is also inconvenient to adjust.

[0004] Now, a novel automatic welding device for connection nodes of power transmission towers is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic welding device for the connection nodes of power transmission towers, so as to solve the problem of lack of auxiliary propulsion mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic welding device for connection nodes of transmission towers, comprising a base and a groove. A groove is provided between the two sides inside the base, and push wheels are movably connected to the two sides at the bottom of the groove. A frame is fixed between the front and rear sides of the top of the base, and a through groove is provided at the center of the top of the frame. A rod is longitudinally inserted into the through groove, and a balance bar is fixed between the left and right sides of two sets of rods. A screw hole is provided between the upper and lower parts inside the rod. A bolt is threadedly connected to the center of the front end of the frame. A bracket is fixed to the bottom of the rod, and a motor is fixed to the front end of the bracket. A guide wheel is movably connected between the front and rear sides of the bracket. Grooves are provided on both sides of the base. A support frame is fixed at the front and rear of the center of the top of the base, and a top plate is fixed between the front and rear ends of the two sets of support frames.

[0007] As a further technical solution of this utility model, the output shaft of the second motor is connected to a guide wheel, and the guide wheel rotates horizontally in the bracket.

[0008] As a further technical solution of this utility model, the bolt passes through the frame and the screw hole, and the insertion rod enters and exits the through groove vertically.

[0009] As a further technical solution of this utility model, an arc-shaped groove is provided between the front and rear of the bottom surface of the support frame, a movable block is installed in the arc-shaped groove, and rollers are longitudinally movably connected to both sides inside the movable block. A motor is fixed to both sides of the upper surface of the movable block, a slot is provided on both sides of the arc-shaped groove, a hanging rod is fixed to the bottom of the movable block, and a welding head is fixed below the hanging rod.

[0010] As a further technical solution of this utility model, the bottom of the output end of the motor is fixedly connected to the roller, and the side of the roller is embedded in the slot.

[0011] As a further technical solution of this utility model, the movable block slides along the inner wall of the arc-shaped groove, and the rollers rotate in opposite directions on both sides inside the movable block.

[0012] As a further technical solution of this utility model, a shell is fixed at the center of the top of the top plate, and a filter box is fixed horizontally inside the shell. The filter box is filled with bamboo charcoal particles. An air pump is fixed at the upper right corner of the shell. Air extraction hoods are fixed on both sides of the bottom of the top plate. Filter screens are fixed at the bottom and top of the filter box.

[0013] As a further technical solution of this utility model, the two sides of the bottom of the shell are respectively connected to the air extraction hood, and the air extraction hood is symmetrically arranged on both sides of the bottom of the top plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the automatic welding device for the connection nodes of the power transmission tower not only realizes the adjustment of the position of the tower accessories and the heating of the splicing joint at multiple positions, but also realizes the purification of the odor generated during welding;

[0015] (1) By connecting the guide wheel between the front and rear of the bracket, hold the balance bar at the center and guide the insert rods on both sides to move up and down along the through groove. After aligning with the screw hole, screw in the bolt to reinforce. The height of the guide wheel above the base can be adjusted. Then start the motor and rotate the guide wheel. With the push wheel at the bottom, push the iron tower accessories horizontally in the groove so that the welding head at the center can be welded. After the welding is completed, push the accessories out of the device.

[0016] (2) By fixing a welding head under the rod, the rollers controlled by the motor are symmetrically distributed on both sides of the movable block, and the two sets of rollers rotate in opposite directions. When the rollers rotate in the groove, they can guide the movable block, the rod and the welding head at the bottom to move along the arc groove together and perform welding at different positions before and after the tower components. The welding position is varied, which can avoid the splice from breaking.

[0017] (3) By filling the filter box with bamboo charcoal particles, and the entire box is suspended in the shell, the odor generated by the welding head heating the iron tower parts or welding material can be absorbed by the suction hood on both sides of the bottom through the suction hood. The odor is then absorbed by the bamboo charcoal particles in the filter box and discharged into the outer space, thus avoiding air pollution and protecting the physical and mental health of the staff.

In conjunction with the push wheel 3 at the bottom, the tower accessories are pushed horizontally in the groove 2 for welding processing at the welding head 25 at the center. The rollers 19 controlled by the motor 17 are symmetrically distributed on both sides of the movable block 21, and the rotation of the two sets of rollers 19 is... In the opposite direction, when the roller 19 rotates in contact with the slot 18, it can guide the movable block 21, the hanging rod 20 and the bottom welding head 25 to move together along the arc groove 16 to perform welding at different positions before and after the iron tower assembly. The filter box 11 is filled with bamboo charcoal particles 12, and the entire box is suspended in the shell 10.
