Description

Technical Field

[0001] The utility model relates to the technical field of vertical welding machines, in particular to a sliding power-taking device of a vertical welding machine. Background Art

[0002] The vertical welding machine is an electroslag furnace electrode welding device. The electrode welding quality is a major indicator for ensuring the quality of steelmaking. In the early stage of smelting, the verticality of the electroslag furnace electrode welding quality affects whether the smelting work can proceed smoothly. Poor vertical welding quality and inappropriate position of the electrode in the smelting container can directly lead to the inability to carry out steelmaking work. If it is forced to be used, arcing may occur and the smelting container may be damaged. Therefore, the quality of welding directly affects whether steelmaking can be carried out.

[0003] In summary, vertical welding machines occupy an extremely important position in the supporting equipment of electroslag furnaces, and the frequency of use of welding machines is also extremely high. In the early days, electrode welding relied on manual welding, and the electrodes were placed horizontally. The consumable electrodes that were connected to the electrodes were also completely manually aligned, which resulted in low production efficiency. The electrode welding was often not vertical, which directly led to low efficiency in steelmaking and production, affecting production. The emergence of welding machines has greatly improved production efficiency and changed the problem of traditional manual alignment, but also brought new problems. Since the electrodes of vertical welding machines are placed vertically, the electrodes are always in a rotating state during welding, and the welding point is fixed in one position, and welding is completed by rotating the electrodes. The traditional vertical welding machine uses manual jacks for manual centering. Although it can meet the welding quality, the centering process is troublesome and requires four manual points to cooperate with each other for centering. The efficiency is also greatly restricted. Therefore, the vertical welding machine is upgraded and transformed. The traditional manual jack centering is changed to a full electric push rod for centering, which greatly improves the centering efficiency. Although the efficiency is improved, since the electrode is rotated for welding every time, the electric push rod also rotates with it every time. The power supply during the rotation process is limited. A separate power supply is used. One push rod is powered by one power supply. The push rod needs to be powered before execution. After the push rod is finished, each push rod needs to be powered off separately. The traditional use of aviation plugs also leaves safety hazards for operation. If the power is not cut off, the push rod rotates, and the push rod power cable can be directly torn off, causing serious leakage and other scenes. Therefore, in order to solve the problem of rotating power supply, a sliding power supply device for a vertical welding machine is specially developed. Utility Model Content
