Description

Technical Field

[0001] The invention relates to the technical field of welding of a power tower base, and in particular to a welding device for a power tower base. Background Art

[0002] In the field of power infrastructure construction, power towers are the key supporting structures of transmission lines. The stability of their bases is directly related to the safety performance of the entire tower. Welding technology is used to firmly connect the various components of the tower base together to ensure the stability and safety of the tower.

[0003] In the welding process of the power tower base, in order to ensure the high stability and strength of the base, it is usually necessary to firmly weld multiple connecting plates on its surface. However, in some factory environments with low automation levels, the welding of these connecting plates still relies on traditional welding methods; this traditional method is prone to shaking when welding the connecting plates to the base because the connecting plates themselves lack sufficient fixed support, which not only causes deviations in the welding position, but also affects the welding quality. Summary of the invention

The present invention provides mutually cooperating parts such as a bidirectional screw rod, a round rod and a pressing plate, and then when the connecting plate is welded, the bidirectional screw rod is driven to rotate synchronously by the rotation of the driving motor, so that the two groups of movable plates meshed with the bidirectional screw rod begin to move relatively, and the short rod and the round rod are driven downward by the movably connected connecting rod, so that the telescopic rod enters the deepest part of the annular groove from the inverted U-shaped groove, and drives the pressing plate to move downward synchronously to press and fix the connecting plate to be welded on the base, thereby ensuring stability during the welding process.

When the moving plate 502 is reset, the straight surface of the driving tooth 704 is engaged with the matching groove 703, thereby driving the turntable 702 to start rotating.

[0028] Specifically, when welding the connecting plate to the surface of the base body 3, the base body 3 is placed on the surface of the carrier plate 2, and then the multiple groups of connecting plates are placed in sequence according to the positions of the positioning grooves 5081 and the driving motor is started.
