A power tower welding device with adjustable welding gun height

Abstract

This invention relates to the field of power transmission tower welding technology, and in particular to a power transmission tower welding device with an adjustable welding torch height. The device includes a movable frame, a pusher fixedly connected to one side of the movable frame, an adjustment mechanism rotatably connected to the movable frame, a windbreak frame rotatably connected to the adjustment mechanism, a rain shield frame rotatably connected to the movable block, and an adjustable welding mechanism slidably fitted inside the movable frame. When welding the base and the power transmission tower column with the welding torch, the adjustment mechanism causes the windbreak frame to unfold an elastic curtain, blocking the area around the welding position. This effectively blocks the influence of wind, maintains a stable airflow in the welding zone, avoids gas shield failure, and reduces the risk of weld oxidation and porosity. This significantly improves the safety and quality of the welding operation. By providing a stable welding environment and reducing external interference, it effectively avoids welding defects, ensuring the structural safety and service life of the power transmission tower.

Description

Technical Field

[0001] The invention relates to the technical field of electric power tower welding, and in particular to an electric power tower welding device with adjustable welding gun height. Background Art

[0002] Power towers are structural facilities used to support power transmission lines, and they mainly serve to suspend and support high-voltage cables. They play a vital role in the power transmission and distribution network, ensuring that electricity is safely and efficiently transmitted from power plants to end users. Power towers are an indispensable part of the power transmission system, and their design and construction are directly related to the safety and efficiency of the power network. Through reasonable design and material selection, power towers can not only effectively support power lines, but also improve in terms of aesthetics and environmental adaptability. With the advancement of technology, power towers will continue to develop towards intelligence and efficiency to meet future energy needs.

[0003] Power tower welding is an important process in the manufacture and assembly of power towers, which is related to the structural strength, safety and service life of the tower. During the welding process, strict processes and standards must be followed to ensure the quality and performance of the welded joints.

[0004] When welding power towers, existing welding equipment usually needs to be used outdoors. When welding power towers outdoors, especially in windy environments, existing welding equipment lacks the necessary protection functions. In gas shielded welding, strong winds may cause unstable flow of shielding gas, which in turn causes defects such as oxidation, pores or inclusions during welding, affecting the quality of the weld. When the wind speed is high, the temperature of the welding area may drop, resulting in insufficient penetration and bonding strength of the weld, which in turn affects the strength and toughness of the welded joint. There are many shortcomings and challenges. These shortcomings may affect welding quality, safety and work efficiency.

[0005] In summary, the prior art lacks the technology for adopting welding protection for power tower welding equipment. Summary of the invention

[0008] Preferably, two rotating rods are rotatably connected on the pushing hand, and a positioning rod is slidably provided on the rotating rod, and one end of the positioning rod is movably engaged with one end of the pushing hand.

[0009] Preferably, an elastic curtain is connected and fixedly arranged at the bottom end of the wind shield frame, and the other end of the elastic curtain is connected and fixedly arranged at the movable frame.

[0010] Preferably, a universal joint is rotatably provided on the moving block, an adjusting wheel is fixedly provided at one end of the universal joint, a rack is meshingly provided on one side of the adjusting wheel, the rack is fixedly connected to the inner wall of the wind shield, a worm B is fixedly provided at the other end of the universal joint, and the worm B is rotatably connected to the moving block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1.

At this time, it can effectively block the influence of wind and maintain a stable airflow in the welding area, thereby avoiding the failure of gas protection and reducing the risk of weld oxidation and porosity, thereby greatly improving the safety and quality of welding operations. By providing a stable welding environment and reducing external interference, it can effectively avoid the occurrence of welding defects and ensure the structural safety and service life of the power tower;

[0014] 2. When welding the base and the power tower column with a welding gun, when it rains, the transmission mechanism can be used to drive the two rain shields close to the power tower column. Under the action of the rubber curtain, a shield will be formed above the welding position, which can effectively prevent rain from falling directly into the welding area and avoid the influence of moisture on the welding quality. It not only improves the welding quality and safety, but also enhances the continuity and efficiency of the operation, making it possible to carry out welding operations under severe weather conditions, which can better ensure the welding quality and construction safety of the power tower;

[0015] 3. By setting a welding gun with adjustable height and angle, it is possible to weld columns of different sizes, thereby improving the practicability of the device. At the same time, an arc frame is set up, which can automatically control the welding gun to weld around the column, replacing manual welding, and can maintain the uniformity and consistency of welding, thereby reducing human errors. At the same time, by setting a positioning rod, the device can be fixed during welding to ensure that the welding gun will not be displaced during operation. This fixity can improve the stability of the welding process, thereby reducing the occurrence of welding defects. BRIEF DESCRIPTION OF THE DRAWINGS
