Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a welding fixture for water conservancy steel frames. Background Technology

[0002] The hydraulic steel frame is the support for hydraulic structures and buildings, as well as the support for hydraulic formwork. It is generally welded on the construction site.

[0003] When welding the base frame and vertical supports of a hydraulic steel frame, the general practice is to position the base frame, manually support the vertical supports, and then weld the connection between the supports and the base frame. During the welding process, the supports inevitably shake, resulting in incomplete welds at the connection between them and the base frame. Therefore, a welding fixture for hydraulic steel frames is proposed. With its ingenious structure, it can simultaneously position the base frame and the vertical supports and provide a welding operating space, making it convenient for technicians to perform the welding. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a welding fixture for hydraulic steel frames to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of the present invention provides a welding fixture for a hydraulic steel frame, including a support leg, a base plate, and a side plate. The top of the support leg is fixedly connected to the base plate, and the edge of the top surface of the base plate is fixedly connected to the side plate. A crossbeam is fixedly connected to the inner corner of the side plate, and the end of the crossbeam has an inclined surface; A screw rod is threaded onto the inclined surface of the crossbeam, and a handle is fixedly connected to the end of the screw rod; The other end of the screw is movably connected to a positioning element, and the end of the positioning element has a positioning notch; The bottom plate and side plate are abutted against the steel frame on their inner sides, and the positioning notch of the positioning member abuts against the corner of the vertical part of the steel frame; A connector is fixedly connected to the top of the base plate, and a screw is threaded onto the connector. A handle is fixedly connected to the end of the screw, and a top block is movably connected to the end of the screw. The top block has two top surfaces, and the top block abuts against the two surfaces inside the steel frame base. A screw head is fixedly connected to the outer surface of the screw rod. The screw head is fastened to the inclined surface and the joint. A hollow part is opened at the corner of the side plate, and the hollow part corresponds to the corner of the steel frame.

[0007] Preferably, in any of the above solutions, the support leg is welded to the base plate, and the base plate is perpendicular to the side plate.

[0008] The above technical solution is adopted: This device is specially used for auxiliary welding of hydraulic steel frames, specifically for auxiliary welding of the vertical rods connecting the steel frame base to the corner of the base surface. It is a special welding fixture for steel frames.

[0009] Preferably, in any of the above schemes, the included angle of the side plate is ninety degrees, and the crossbeam is welded to the corresponding side plate.

[0010] The above technical solution is adopted: the device is divided into three parts. The first part is the main body, which consists of legs, a base plate and side plates. The base plate is used to place the steel frame. The vertical rods of the steel frame are attached to the side plates at a 90-degree angle. The connection between the steel frame and the vertical rods is exposed through the hollow part to facilitate welding operations. The second part, the upper positioning part, is used to position the vertical bars of the steel frame. It consists of a horizontal beam, an inclined surface, a screw, a handle, a positioning component, a positioning notch, and a screw head. The third part, the lower positioning part, is the base frame used to position the steel frame. It consists of a connector, screw, handle, top block, and screw head.

[0011] Preferably, in any of the above solutions, the screw is arranged laterally and the included angle of the positioning notch is ninety degrees.

[0012] The core structure of this device, using the above technical solution, consists of: a base plate, side plates, a crossbeam, an inclined surface, a screw, a handle, a positioning component, a positioning notch, a screw head, a connector, a top block, and a screw head. This device can simultaneously clamp and position the base frame of the steel frame and the vertical members to be welded at its corners, facilitating welding. A new clamping structure is designed: the base plate holds the steel frame, the vertical members of the steel frame rest against the 90-degree angle of the side plate, and the connection between the steel frame and the vertical members is exposed through a perforated section for easy welding. By rotating the screw with the handle, the screw head tightens on the inclined surface of the crossbeam, and the positioning component, in conjunction with the positioning notch, presses the vertical members firmly against the angle of the side plate. By rotating the screw with the handle, the screw head tightens onto the joint, and the top block presses against the inside of the steel frame's base, thus achieving synchronous positioning and clamping of the steel frame base and the vertical pole to be welded. The clamping is firm, and no manual handling is required during welding. The connection between the steel frame and the vertical pole is exposed through the perforated section, facilitating welding operations. Technicians only need to perform the welding operation, greatly shortening preparation time and improving overall welding efficiency. This improved welding quality and reduced production and time costs.

[0013] Preferably, one corner of the steel frame abuts against the included angle of the side plate, and the joint is welded to the base plate.

This hydraulic steel frame welding fixture, through the coordinated arrangement of a base plate, side plates, crossbeams, inclined surfaces, screws, handles, positioning components, positioning notches, screw heads, joints, top blocks, and screw heads, can simultaneously clamp and position the base frame of the steel frame and the vertical rods to be welded at its corners, facilitating welding of both. A new fixture structure is designed, with the base plate used to place the steel frame, the vertical rods of the steel frame abutting against the 90-degree angle of the side plates, and the connection between the steel frame and the vertical rods exposed through a perforated section for easy welding operation. By rotating the screws with the handle, the screw heads are tightened on the inclined surfaces of the crossbeams, and the positioning components, in conjunction with the positioning notches, press the vertical rods against the angle of the side plates. By rotating the screw with the handle, the screw head is tightened on the joint, and the top block is pressed against the inner side of the steel frame base, thereby achieving synchronous positioning and clamping of the steel frame base and the vertical rod to be welded. The clamping is firm, and no manual handling is required during the welding process. The connection between the steel frame and the vertical rod is exposed through the hollow part, which facilitates the welding operation. Technicians only need to perform the welding operation, which greatly shortens the preparation time and improves the overall welding efficiency. 2.
