Description

Technical Field

[0001] This utility model relates to the field of steel cage welding technology, specifically a steel cage welding device for road and bridge construction. Background Technology

[0002] Reinforcing cages play an indispensable role in construction engineering, especially in structures such as bridges and pile foundations. The manufacturing process of reinforcing cages generally involves clamping and fixing multiple main reinforcing bars into a circle or square shape, and then wrapping stirrups around the main reinforcing bars and welding them at the connection between the main reinforcing bars and stirrups. In the actual production process of reinforcing cages, in order to facilitate the equipment for clamping the main reinforcing bars, reinforcing cages of different diameters can be made, and various main reinforcing bars of different diameters can be clamped. This utility model proposes a welding device for reinforcing cages of road bridges. Summary of the Invention

[0003] The purpose of this utility model is to provide a welding device for steel cages of road and bridge reinforcement to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a welding device for steel cages of road bridges, comprising a fixed clamping frame and a movable frame. A rotating frame is rotatably mounted on the fixed clamping frame and the movable frame. The rotating frame is hollow and ring-shaped, with an mounting plate fixedly mounted on its inner ring. A limiting ring can be installed on the mounting plate via bolts. A connecting hole is provided on the limiting ring, and a connecting piece is detachably mounted on the connecting hole. A movable guide rail is fixedly connected to the side of the fixed clamping frame. The movable guide rail passes through the movable frame and is slidably connected to the movable frame. A movable wheel is rotatably mounted on the bottom of the movable frame. In use, one end of the main reinforcing bar can be passed through the connecting frame on the fixed clamping frame and fixedly clamped onto the connecting piece of the movable frame. As the movable frame pulls the main reinforcing bar, the rotating frame rotates and wraps the stirrup around the main reinforcing bar. A worker can then use a handheld welding device to weld the connection between the stirrup and the main reinforcing bar. Alternatively, automated welding equipment can be used, such as resistance welding, where upper and lower electrode plates contact the main reinforcing bar and stirrup respectively, creating a conductive path. Current flows through the contact point, generating high temperature to melt the metal and perform welding.

[0005] Preferably, the fixed clamping frame and the movable frame are provided with annular grooves, and the rotating frame is slidably disposed within the annular grooves. A limiting groove is provided on the outer side of the rotating frame, and a protrusion is provided on the inner wall of the annular groove that slidably connects with the limiting groove. The slidable arrangement of the rotating frame facilitates the welding of the stirrups around the main reinforcement.

[0006] Preferably, a rack is provided on the outer ring of the rotating frame on the fixed clamping frame, and a gear meshing with the rack and a motor capable of driving the gear to rotate are rotatably provided inside the fixed clamping frame. A motor for driving the bottom wheels of the movable frame to rotate is also provided at the bottom of the movable frame.

[0007] Preferably, the connector has a tubular channel at its center for the rebar to pass through, and one end of the channel is provided with multiple clamping plates. The clamping plates have a ramp on the side away from the center of the channel. The outer side of one end of the connector is threaded and screwed with a push block and a locking nut. The principle of clamping one end of the main rebar using the connector is that rotating the push block causes it to contact the ramp on the clamping plate, compressing the ramp and clamping plate towards the center of the connector channel. This generates a clamping force on the main rebar within the connector channel, thus clamping the main rebar. For main rebars of different diameters, connectors with corresponding channels for the main rebar to pass through can be custom-made. Customizing a limiting ring with a corresponding channel for each size can save material costs.

[0008] Compared with the prior art, the beneficial effects of this utility model are: by setting a fixed clamping frame, a movable frame, a rotating frame, a limiting ring and a connector, it is possible to conveniently clamp multiple main bars to form the shape of the steel cage to be made, and to wrap the stirrups. The detachable design of the connector and the limiting ring makes it convenient to clamp main bars of different sizes while replacing the connecting holes with different shapes and positions to meet the needs of making steel cages of different shapes.
