Description

Technical Field

[0002] The aerial platform is a kind of equipment used for aerial work. It enables operators to safely reach and stay at high places through a retractable or liftable working platform. The curved edge design of the platform on which the aerial platform stands has many advantages over the right-angle edges, including improved safety, enhanced stability, optimized work efficiency, improved comfort and aesthetics, and enhanced durability. These advantages make the curved edge design widely used and recognized in the manufacture of aerial platforms.

[0003] The mobile platform of the aerial platform adopts a curved edge design. Compared with the right-angle edge, the curved design can better adapt to the standing posture of the human body. However, the curved edge needs to be constantly adjusted during welding and the weld needs to be kept parallel. Conventional welding is difficult. Due to the curved surface design, a clamp is required to fix it during welding to avoid deflection during welding. After welding, the remaining welding slag around the weld and the welding mark left by high temperature need to be cleaned.

[0015] Compared with the prior art, the present invention provides a clamp for welding a movable platform of an aerial platform, which has the following beneficial effects:

[0016] 1. Through the cooperation between the cylinder and the arc-shaped clamping ring, the arc edges on both sides of the fence body and the base plate body can be limited to avoid offset during welding, making the welding process more stable. Through the cooperation between the first gear and the clamping tooth, the welding head can always fit the weld on the arc edge for welding, avoiding additional angle adjustment. The translational welding head makes the welding process more efficient, especially in mass production environments, which can significantly improve the welding speed. Through the cooperation between the first electric telescopic rod and the welding head, the welding head can always fit the weld to avoid manual operation, so that welding operations can be carried out continuously and stably, reducing the uncertainty and discontinuity of manual operation. The operator only needs to monitor the operating status and welding quality of the equipment, reducing the work intensity.

[0017] 2. Through the cooperation between the second gear and the first rotating rod, the first rotating rod can drive the stirring rod to stir the acid liquid to avoid acid liquid deposition and affect the cleaning effect, thereby improving the cleaning quality of the weld and weld mark. Through the cooperation between the push plate and the discharge pipe, the spray head can output acid liquid to the weld to corrode the weld after welding, which can effectively remove the oxide scale, welding slag, rust and other pollutants in and around the weld, and make the metal surface smoother and flatter. This is conducive to improving the quality of subsequent processing, such as cutting, stamping, welding, etc., as well as improving the adhesion and aesthetics of the surface coating. Through the mutual cooperation of the first spring and the inlet hole, continuous output of acid can be avoided, thereby avoiding waste of resources. The mutual cooperation of the first rotating shaft and the second rotating shaft drives the synchronous belt to rotate, so that the frosted surface of the synchronous belt is used to clean the welds after pickling, and the weld marks and other impurities caused by high-temperature welding around the welds are cleaned. Friction cleaning can remove a small amount of acid and other impurities remaining on the metal surface after pickling, ensuring thorough cleaning of the metal surface. The roughness of the metal surface can be increased through friction, which is conducive to the bonding force between the coating or plating and the metal substrate, and improves the adhesion and durability of the coating.

[0018] 3. Through the cooperation between the sleeve and the second rotating rod, the grinding block can be rotated to carry out targeted cleaning of the welds between the fence body and the base plate body. Comprehensive cleaning of impurities such as welding slag remaining on the weld surface can significantly improve the quality of the weld. Through the cooperation between the convex plate and the third rotating rod, the grinding block can also move up and down when rotating, so that the weld and the surrounding area of ​​the weld can be comprehensively polished, thereby improving the overall quality of the metal surface around the weld, including smoothness, flatness and corrosion resistance.
