[0047] The steel cage manufacturing tire frame of the present embodiment has a main tire frame pallet and a fixed plate arranged parallel to each other and both arranged vertically on the base, and the auxiliary tire frame pallet and the fixed plate can be flipped and connected.

[0053] Optionally, multiple angle steels are arranged in mirror symmetry on both sides of the main tire frame pallet 1, and the angle steels on each side of the main tire frame pallet 1 are arranged in rows, and the upper end faces of each row of angle steels are located on the same horizontal plane, that is, the lower end faces of each row of angle steels are also located on the same horizontal plane.

[0054] In this embodiment, three rows of angle steels are provided on each side of the main tire frame clamping plate 1, and the bottom row of angle steels is arranged close to the fixing plate 3. Preferably, the second folded edge portion of the bottom row of angle steels is welded and fixed to the corresponding fixing plate 3, and the stability of the fixing plate 3 can be further increased by welding and fixing the second folded edge to the fixing plate 3.

[0055] Optionally, the first folded edges of the angle steels in the non-bottommost row are arranged horizontally, and the first folded edges of the angle steels in the bottommost row are arranged vertically, so as to facilitate welding with the fixing plate 3 .

[0056] In other embodiments, the connecting member 52 may also be a U-shaped steel, which includes a first arm and a second arm arranged parallel to each other, and a horizontal plate connecting the two.

The opposite sides of each first hinge body 61 and the second hinge body 62 are provided with a hinged protrusion for the flip shaft 63 to pass through. The auxiliary tire frame plate 2 adjusts its direction by rotating the flip shaft 63 to approach and move away from the main tire frame plate 1.

[0062] Preferably, the above-mentioned pallet assembly is provided with two groups, and the two groups of pallet assemblies are respectively arranged on both sides of the above-mentioned main tire frame pallet 1.

[0063] In this embodiment, three types of steel cages with different diameters can be manufactured by using a main tire frame pallet 1 and two auxiliary tire frame pallets 2 to meet the actual basic needs of on-site construction.

[0064] In this embodiment, the upper end faces of the main tire frame pallet 1 and the auxiliary tire frame pallet 2 are both arc-shaped with one-third of a circle, and the diameter of the arc of the upper end face of the main tire frame pallet 1 is larger than the diameter of the arc of the upper end face of any auxiliary tire frame pallet 2.

The other end of the spring 7 is provided with a hook 8 for hanging steel bars. When the steel bars are placed in the U-shaped groove 4, they can be hung on the steel bars through the hook 8 to achieve further limiting effect on the steel bars and prevent the steel bars from escaping from the U-shaped groove 4.

[0069] When it is necessary to make steel cages of other diameters, each steel cage is adjusted to make a tire frame, and the specific steps include:

[0070] First, all the fastening bolts on the auxiliary tire frame clamping plate 2 corresponding to the steel reinforcement cage of non-corresponding diameter are taken out, and the auxiliary tire frame clamping plate 2 is flipped by the flipping assembly 6 until one end is against the ground.

[0071] Then, another auxiliary tire frame pallet 2, that is, the auxiliary tire frame pallet 2 corresponding to the steel cage of the corresponding diameter, is flipped by the flip assembly 6 to fit closely with the angle steel, and the fastening bolts are passed through the waist round hole of the auxiliary tire frame pallet 2 and the through hole of the second folded edge of the angle steel in sequence, and then fastened with the positioning nut to complete the positioning of the auxiliary tire frame pallet 2. Then, the steel cage of the required diameter can be processed.

[0072] For steel cages of different diameters, it is only necessary to make several steel cage manufacturing frames according to the length of the steel cages, and then replace the corresponding frame pallet for each steel cage manufacturing frame, and then adjust each steel cage manufacturing frame according to the above steps.

[0073] When manufacturing the steel cage, the hook 8 on each spring 7 can also be hung on the corresponding main reinforcement to fix the main reinforcement and prevent the main reinforcement from escaping from the U-shaped groove 4.
