Description

Technical Field

[0001] The utility model relates to a steel cage double stirrup pay-off frame, belonging to the technical field of roll welding machines. Background Art

[0002] Roll-welded rebar cages are a common reinforcement structure used in building and bridge construction, primarily to enhance the bearing capacity and tensile strength of concrete. Roll-welded machines weld rebar into circular or spiral-shaped cages. Roll-welded rebar cages are widely used in projects such as pile foundations, tunnel linings, and underground diaphragm walls.

[0003] During the welding process, the roll welder rotates to extract the steel coil (hoops) placed on the pay-out stand. At present, the support shaft of the traditional pay-out stand is placed vertically, and the vertical pay-out stand has exposed some shortcomings during use: first, the outlet position of the steel bars on the vertical pay-out stand changes up and down. When the wire is output to a high position, the pay-out stand is subjected to a greater torque and is easily pulled down and overturned, resulting in interruption of wire pay-out. Second, the inner diameter of the intermediate shaft of the traditional pay-out stand is fixed, and the inner ring of the steel coil cannot be tightened from the inside. As a result, the steel coil shakes on the pay-out stand during the pay-out process, reducing the welding stability of the steel cage. Utility Model Content

[0004] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, to provide a double-stirrup pay-off stand for a steel cage, and to improve the stability of the stirrup pay-off during welding of the steel cage.

[0005] The utility model discloses a steel cage double stirrup pay-off frame, which comprises a roller module for placing steel bar coils which is rotatably arranged on a support frame.

[0006] The roller module includes: a support shaft assembly, with a base plate and a baffle plate at both ends of the support shaft assembly, and the baffle plate is fixedly connected to the support shaft assembly through a limit pin; a baffle pin is passed through the support frame to prevent the support shaft assembly from detaching.

[0007] Furthermore, the support shaft assembly includes: a support shaft, one end of the support shaft is fixedly connected to the base plate, and the baffle can be sleeved on the end of the support shaft away from the base plate.

[0008] A plurality of telescopic cylinders are arranged on the outer side of the supporting shaft, one end of the telescopic cylinder is fixedly connected with a supporting plate, and one side of the supporting plate is slidably connected to the base plate.

[0009] One end of the supporting shaft is provided with a shaft ring for limiting the baffle.

[0010] Furthermore, a first positioning hole is provided at one end of the support shaft close to the baffle, and a second positioning hole is provided on the baffle; and the limiting pin is passed through the first positioning hole and the second positioning hole.

[0011] Furthermore, the support plate is arc-shaped, a holder is provided on the inner side of the support plate, and the output end of the telescopic cylinder is connected to the holder; a slider is provided at one end of the support plate.

[0012] Furthermore, the supporting shaft is hollow, and an interface for controlling the movement of the telescopic cylinder is provided at one end of the supporting shaft close to the base plate.

[0013] Furthermore, a plurality of guide grooves are provided on the base plate, and the sliders are slidably connected to the guide grooves.

[0014] Furthermore, the support frame includes: a base, a vertical frame is arranged on the top of the base, and a reinforcing rod is also arranged on the side of the vertical frame; and an open-shaped rotating seat is arranged at the top of the vertical frame.

[0015] Furthermore, the rotating seat is in a flared shape, and the end of the supporting shaft is clamped into the rotating seat; the stop pin is passed through the rotating seat to restrict the supporting shaft in the rotating seat.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The steel coil is placed horizontally on the support frame along with the support shaft assembly, which reduces the wire-out height of the steel coil during pay-out and prevents the pay-out frame from being pulled and overturned during the pay-out process; further, the support shaft assembly tightens the inner ring of the steel coil through a retractable support plate, thereby stably fixing the steel coil to the support shaft assembly, ensuring that the steel coil rotates stably during the pay-out process.
