Description

Technical Field

[0001] The invention relates to the technical field of pile foundation steel cage processing, in particular to stirrup processing equipment for pile foundation steel cages. Background Art

[0002] Pile foundation is a deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation. If the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. The building pile foundation is usually a low cap pile foundation. Pile foundations are widely used in high-rise buildings.

[0003] When carrying out pile foundation construction, it is also necessary to make a steel cage for reinforcing the pile foundation. When processing the stirrups on the steel cage, it is necessary to be bent according to the needs of use. Patent publication number CN220992698U is a device for processing stirrups of pile foundation steel cages. Its structure mainly includes a base, a bending shaft and a rotating disk arranged on the outer side of the bending shaft. A plurality of support rods are evenly arranged on the rotating disk, each support rod is provided with a movable first sliding seat, and a clamping cylinder is provided on the first sliding seat; by adjusting the position of the plurality of first sliding seats, the bending radius of the stirrups can be adjusted, and the ends of the steel bars are clamped by the clamping cylinder and the bending cylinder, and the bending process is achieved by the rotation of the rotating disk.

[0004] However, when adjusting the positions of multiple first sliding seats, the above-mentioned device can only adjust them one by one manually, which is cumbersome to operate, and the adjusted positions may have problems such as deviation, which affects the processing effect; when processing stirrups with a larger radius, the first sliding seat needs to adjust the position outward, and as the adjustment distance increases, the distance between two adjacent first sliding seats will also increase, which will result in a reduction in the bending effect of the stirrups during the bending process.

[0050] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0051] Embodiment 1

[0052] Please refer to the accompanying drawings, the present invention provides a technical solution:

[0053] A stirrup processing device for pile foundation steel cage, comprising a base 100 and a workbench 101 located above the base 100, wherein the workbench 101 is fixedly connected to the base 100 through two support plates 102, a feeding assembly is provided on one side of the top of the workbench 101, and a circular groove is provided at the center of the workbench 101, and a stirrup bending mechanism is provided at the circular groove;

[0054] The stirrup bending mechanism includes a rotating circular groove 300, in which a plurality of fixed adjustment components and rotating adjustment components are evenly arranged along the circumferential direction, and the fixed adjustment components and the rotating adjustment components are arranged in sequence and spaced apart, and a limiting structure 700 is provided on each of the fixed adjustment components and the rotating adjustment component, and a positioning structure is provided on the outer side of the limiting structure 700 located on one of the fixed adjustment components;

[0055] The bottom of the rotating circular groove 300 is rotatably connected to the workbench 101 through a rotating assembly. A center box 302 is provided at the center of the inner cavity of the rotating circular groove 300, and a fixed ring seat 400 is provided on the inner side wall of the rotating circular groove 300. The fixed adjustment assembly and the rotating adjustment assembly are arranged in the annular area between the center box 302 and the fixed ring seat 400. The two ends of the fixed adjustment assembly are respectively connected to the center box 302 and the fixed ring seat 400. The inner side end of the rotating adjustment assembly is rotatably connected to the fixed adjustment assemblies adjacent to the two sides, and the bottoms of the multiple rotating adjustment assemblies are commonly connected to a position switching assembly.

[0056] A first transmission assembly and multiple second transmission assemblies are provided inside the fixed ring seat 400. The outer ends of the multiple fixed adjustment assemblies are correspondingly connected to the first transmission assembly, and the outer ends of the multiple rotating adjustment assemblies are correspondingly connected to the first transmission assembly through the corresponding second transmission assemblies.

[0057] When processing stirrups, if stirrups with larger diameters are being processed, the limiting structures 700 on the fixed adjustment component and the rotating adjustment component are both involved in the processing, and the fixed adjustment component and the rotating adjustment component are driven simultaneously through the first transmission component and the second transmission component, and drive the limiting structures 700 thereon to move along the radial direction of the rotating circular groove 300, so that the positions of all limiting structures 700 are adjusted according to the requirements of the processing radius, and the loading component automatically adjusts its position so that it can correspond to the position of the limiting structure 700 and work in coordination with each other.

[0058] The stirrups are moved along the feeding assembly toward the rotating circular groove 300 manually or by external devices, so that the ends of the stirrups are located between the limiting structure 700 and the positioning structure. The limiting structure 700 limits the radius of the stirrups during bending processing and limits the height position of the stirrups to avoid the stirrups from falling during processing, and the positioning structure and the end position of the stirrups are clamped and limited; then the rotating assembly drives the rotating circular groove 300 and the structure thereon to rotate, thereby driving the stirrups to rotate and bend, thereby realizing the processing of the stirrups.

[0059] When processing stirrups with a smaller radius, multiple rotating adjustment components are transmitted through the position switching component, and the rotating adjustment component is disconnected from the second transmission component, so that the limiting structure 700 on the rotating adjustment component can be staggered in height position with the limiting structure 700 on the fixed adjustment component, and then the positions of the corresponding multiple limiting structures 700 are adjusted through the fixed adjustment component, so as to adjust the positions of the multiple limiting structures 700 relative to the rotating circular groove 300 according to the processing radius of the stirrups.

[0060] Therefore, the present invention increases the processing range of stirrups by setting a rotation position switching component, and when the spacing between the limiting structures 700 on two adjacent fixed adjustment components decreases, the rotation adjustment component and the limiting structure 700 thereon are rotated out from between the two limiting structures 700 to avoid affecting the movement of the limiting structure 700 on the fixed adjustment component;

[0061] When the spacing between the limiting structures 700 increases, the position of the rotating adjustment component is adjusted so that the upper limit structure 700 is inserted between the two fixed adjustment component limiting structures 700 to avoid the spacing between two adjacent limiting structures 700 being too large to affect the stirrup processing effect.

[0063] When the fixed adjustment component is working, the multiple first screws 502 are rotated simultaneously through the drive of the motor and the transmission of the second bevel gear 504 and the third bevel gear 505, so that all the first moving blocks 503 drive the corresponding limiting structures 700 to move and adjust the position of the limiting structures 700.

[0064] Among them, the rotation adjustment component includes a rotation adjustment seat 600, the bottom of the rotation adjustment seat 600 is connected correspondingly to the position switching component, and a rotation groove is provided at the bottom of the rotating circular groove 300 corresponding to the position of the rotation adjustment seat 600, a rotation shaft 601 is fixed to the inner end of the rotation adjustment seat 600, and a rotation shaft mounting block 501 is fixed to the side walls of the adjacent fixed adjustment seats 500 on both sides, and the end of the rotation shaft 601 is rotatably connected to the rotation shaft mounting block 501, and the interior of the rotation adjustment seat 600 is slidably connected to a second moving block 603, and a second screw 602 is rotatably connected in the second moving block 603, and the second screw 602 is rotatably connected to the rotation adjustment seat 600, and a transmission groove 604 is provided at one end of the second screw 602 close to the fixed ring seat 400, and is correspondingly connected to the second transmission assembly through the transmission groove 604.

[0065] When the rotating adjustment assembly is working, the rotating adjustment seat 600 is in a horizontal state and at the same height position as the fixed adjustment seat 500. When the first screw 502 rotates, the second screw 602 is rotated synchronously through the first transmission assembly and the second transmission assembly, thereby causing the first moving block 503 and the second moving block 603 to move simultaneously along the radial direction of the rotating circular groove 300 to adjust the positions of all the limiting structures 700.

[0066] Among them, the first transmission assembly includes a second bevel gear ring 401 rotatably connected to the inside of the fixed ring seat 400, and the second bevel gear ring 401 is located on the inner wall of the fixed ring seat 400 away from the fixed adjustment seat 500, a fourth bevel gear 506 is fixed to the end of the first screw rod 502, the fourth bevel gear 506 is meshed with the second bevel gear ring 401, and a fifth bevel gear 402 is meshed at the position corresponding to each second screw rod 602 on the second bevel gear ring 401, and a gear shaft 403 is fixed at the center of the fifth bevel gear 402, a fixed bracket 404 is provided inside the fixed ring seat 400, the gear shaft 403 is rotatably connected to the fixed bracket 404, and a second transmission assembly is connected to the gear shaft 403, and is correspondingly connected to the transmission groove 604 of the second screw rod 602 through the second transmission assembly.

[0067] When multiple first screws 502 rotate, the same second bevel gear ring 401 is driven simultaneously by multiple fourth bevel gears 506, so that multiple fifth bevel gears 402 rotate simultaneously. When the second screw 602 needs to be rotated, the second transmission assembly rotates with the transmission wheel and the second screw 602 at the same time, so that the synchronous rotation of all the first screws 502 and the second screw 602 is achieved simultaneously through the first transmission assembly and the second transmission assembly; when the rotating adjustment seat 600 is not working, its position is staggered with the position of the fixed ring seat 400, and the second transmission assembly is disconnected from the second screw 602, so that the rotation of the first screw 502 will not drive the second screw 602 to rotate.

[0068] Wherein, the second transmission assembly includes a transmission cylinder 405 slidably sleeved on the gear shaft 403, and a transmission hole is provided on the side wall of the fixed ring seat 400 close to the second screw rod 602 at a position corresponding to the transmission cylinder 405, a connecting strip is fixed on the inner side wall of the transmission cylinder 405, a connecting groove is correspondingly provided on the gear shaft 403, and the connecting strip on the transmission cylinder 405 is slidably connected to the connecting groove of the gear shaft 403, a transmission shaft 406 is fixed at the end of the transmission cylinder 405, a connecting strip is provided on the transmission shaft 406, a connecting groove is correspondingly provided on the inner side wall of the transmission groove 604 of the second screw rod 602, and the connecting strip of the transmission shaft 406 is correspondingly connected to the connecting groove in the second screw rod 602;

[0069] A movable bracket 407 is provided on one side of the fixed bracket 404, and the bottom end of the movable bracket 407 is slidably connected to the bottom of the inner cavity of the fixed ring seat 400, and the transmission cylinder 405 is rotatably connected to the top of the movable bracket 407, and a limiting shaft 408 is fixed between the fixed bracket 404 and the side wall of the fixed ring seat 400, and the limiting shaft 408 passes through the movable bracket 407 and is slidably connected to the movable bracket 407, and the side of the movable bracket 407 away from the fixed bracket 404 is connected to the inner wall of the fixed ring seat 400 through a spring, and electromagnets 409 are respectively provided at the relative positions of the movable bracket 407 and the side walls of the fixed ring seat 400, and the electromagnets 409 are electrically connected to a power supply and a switch.

[0070] When the rotating adjustment seat 600 is in a horizontal state, the position of the second screw 602 is opposite to the position of the transmission shaft 406, and then the electromagnet 409 is energized to attract each other, so that the movable bracket 407 drives the transmission cylinder 405 to move in the direction of the second screw 602, so that the end of the transmission shaft 406 extends into the transmission groove 604 of the second screw 602 while the transmission cylinder 405 and the gear shaft 403 remain connected. When the gear shaft 403 rotates, the second screw 602 is driven to rotate through the transmission cylinder 405 and the transmission shaft 406, so that all the first screws 502 and the second screws 602 rotate synchronously, and the positions of all the limiting structures 700 are adjusted at the same time, the positions of multiple limiting structures 700 are kept consistent, and the effect of stirrup processing is ensured.

[0073] When the end of the stirrup is between the limiting structure 700 and the positioning structure, the outer stop wheel 707 is moved by the fourth hydraulic telescopic rod 705, and the stirrup is compressed and limited by the outer stop wheel 707 and the inner stop wheel 702. During the rotation of the rotating circular groove 300, the stirrup is bent by cooperating with the inner stop wheel 702 on the plurality of limiting structures 700 through the feeding assembly, and the second support wheel 703 provides support and limiting effect on the bottom of the stirrup to avoid the stirrup falling off during the bending process.
