Description

Technical Field

[0001] The utility model relates to a device for manufacturing a circular stiffening hoop of a pile foundation steel reinforcement cage. Background Art

[0002] During the construction process of pile foundation projects, a large number of circular stiffening hoops need to be processed. The general manufacturing method is to first bend the steel bars with a steel bar bender, then place the bent steel bars in a circular mold for positioning, and finally weld them into a ring. The technical problem existing in the prior art is that the mold for circular steel bars can only fit one size. To improve the versatility of the mold, CN220387778U discloses a processing device for adjusting the diameter of the stirrups of a pile steel reinforcement cage, which designs a plurality of movable baffles that can move radially. The size is adjusted by adjusting the radial position of the movable baffles. However, this structure also has obvious defects, that is, the adjustment of each movable baffle is independent. If there are several baffles, they need to be adjusted several times, and each movable baffle needs to be finely adjusted to ensure that each baffle is on the same circumference. Summary of the Invention

[0003] Aiming at the problem of cumbersome adjustment operation existing in the prior art for the processing device for adjusting the diameter of the stirrups of a pile steel reinforcement cage, a device for manufacturing a circular stiffening hoop that is easy to operate is provided.

[0004] The technical solution of the utility model is as follows:

[0005] A device for manufacturing a circular stiffening hoop of a pile foundation steel reinforcement cage includes an upper cover body 1, a slider 2, and a lower base 3. The lower base 3 is of a disc structure, and there is a regular hexagon-shaped chute 31 on the upper surface. Six sliders 2 are arranged on the upper surface of the lower base 3. The inner sides of the six sliders 2 are spliced into a regular hexagon. The upper cover body 1 is composed of a cylinder and a ring at the end face of the cylinder. The inner surface of the cylinder cooperates with the outer surface of the lower base 3. Six guide grooves 11 arranged in a rotating and radial pattern are provided on the ring. Upper guide posts 21 and lower guide posts 22 are respectively arranged on the upper and lower surfaces of each slider 2. The upper guide posts 21 are inserted into the guide grooves 11, and the lower guide posts 22 are inserted into the chutes 31. The stiffening hoop to be welded is limited by the six sliders 2.

[0006] Rotating handles 12 are installed on both sides of the upper cover body 1.

[0007] The size of the regular hexagon formed by the inner sides of the six sliders 2 is changed by rotating the upper cover body 1 through the handle 12.

[0008] After the stiffening hoop is limited by the slider 2, an equilateral triangle-shaped reinforcing rib is welded inside the stiffening hoop.

[0009] The slider 2 is trapezoidal

[0010] The beneficial effect of the present invention is:

[0011] Compared with the prior art,

[0012] 1) By rotating the cover, the hexahedron composed of six sliders can be synchronously controlled to conveniently adjust the required limit size.

[0013] 2) The finished device can be reused many times. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further introduced below in conjunction with the accompanying drawings and specific embodiments:

[0019] Embodiment: A manufacturing device for an annular reinforcing hoop of a pile foundation steel cage includes an upper cover 1, a slider 2 and a lower base 3. The lower base 3 is a disc structure with a regular hexagonal slide 31 on the upper surface. Six sliders 2 are arranged on the upper surface of the lower base 3. The slider 2 is a trapezoidal plate with the lower bottom edge of the trapezoid facing inward. The inner side surfaces of the lower bottom edges of the six sliders 2 are spliced ​​into a regular hexagon. The upper cover 1 is composed of a cylinder and a circular ring on the upper end face of the cylinder. The inner surface of the cylinder cooperates with the outer surface of the lower base 3. Six guide grooves 11 arranged in a rotating radial shape are opened on the circular ring. Each guide groove 11 rotates outward at a certain angle compared to its corresponding slide 31. The upper and lower surfaces of each slider 2 are respectively provided with an upper guide column 21 and a lower guide column 22, and the upper guide column 21 and the lower guide column 22 are coaxial. The upper guide post 21 is inserted into the guide groove 11, and the lower guide post 22 is inserted into the slide groove 31; the stiffening hoop to be welded is limited by six sliders 2, and after the stiffening hoop is limited by the sliders 2, a regular triangle reinforcement rib is welded inside the stiffening hoop. .
