[0012] The invention also provides a stirrup adjusting device.

[0013] The stirrup adjustment device of the present invention provides the following technical solutions:

[0018] Support frame;

[0019] The centering frame is slidably arranged on the top of the support frame, and the centering frames of the two centering adjustment units are moved closer or farther away from each other by sliding along the support frame.

[0020] As a further optimized technical solution, an adjustment plate is provided on the side of the centering frame facing the cache frame, and the adjustment plates of the two centering adjustment units jointly define stirrups from both sides to align the stirrups; the adjustment plate is evenly arranged with grooves for placing stirrups along the length extension direction.

[0021] As a further optimized technical solution, a support wheel for supporting the bottom of the stirrup is provided under the adjustment plate, and a lifting drive structure is provided under the support wheel to drive the support wheel to rise or fall.

The adjustment plate and its groove structure on the centering frame further optimize the alignment effect of the stirrups, so that the stirrups can be arranged in an orderly manner during the adjustment process. The coordination of the support wheel and the lifting drive structure not only facilitates the movement of the stirrups, but also allows the height position of the stirrups to be flexibly adjusted when needed, thereby improving the convenience of operation. The first limiting wheel and the second limiting wheel of the placement rack accurately limit the position of the stirrup cache rack on the centering adjustment unit and the transportation equipment respectively, ensuring the stability and reliability of the entire processing process, and reducing the risk of processing errors caused by equipment shaking or displacement.

[0030] To sum up, the stirrup cache rack and adjustment device of the present invention can significantly improve the caching, adjustment and transportation efficiency of stirrups during the processing of rectangular steel bar skeletons, improve processing accuracy, reduce production costs, and have broad application prospects and promotion value in the field of construction steel bar skeleton processing.

DETAILED DESCRIPTION

[0041] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a direct connection or an indirect connection through an intermediate component. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0043] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0044] The shapes and sizes of the components in the drawings do not reflect the actual proportions of the products, and are only intended to illustrate the contents of the present invention.

[0045] The present invention provides a stirrup cache rack and an adjustment device. Through two centering adjustment units, a group of stirrups placed on the stirrup cache rack can be efficiently aligned longitudinally as a whole, thereby ensuring the accuracy of the coordination between the stirrups and the longitudinal bars in subsequent processing. The transportation equipment is used for the transfer of the stirrup cache rack between different processing stations, thereby reducing the labor intensity and time cost of manual handling and improving production efficiency.

[0046] Embodiment of stirrup slow adjustment device

[0047] like Figure 1-8 For details, please refer to Figure 1 、 Figure 2 The stirrup adjustment device includes a stirrup buffer rack, a centering adjustment unit 300 and a transportation device 400.

[0048] like Figure 3 As shown, the stirrup buffer frame includes a support base frame 100 having two relatively parallel supporting longitudinal beams 110. A connecting crossbeam 120 is disposed between the two supporting longitudinal beams 110. One end of the connecting crossbeam 120 is fixedly connected to one supporting longitudinal beam 110, and the other end is fixedly connected to the other supporting longitudinal beam 110. The supporting longitudinal beams 110 and the connecting crossbeam 120 together form the frame structure of the support base frame 100. In this embodiment, the supporting longitudinal beams 110 and the connecting crossbeam 120 are made of high-quality steel beams, which have high strength and good rigidity, sufficient to stably support the batch of stirrups 200.

[0049] The connecting crossbeam 120 includes a sleeve 121 and a connecting rod 122, one end of which extends into the sleeve 121 and slides with the sleeve 121. The sleeve 121 and the connecting rod 122 slide relative to each other to adjust the overall length of the connecting crossbeam 120, thereby adjusting the distance between the two supporting longitudinal beams 110, and further allowing the support base 100 to adapt to the buffering requirements of stirrups 200 of different specifications. In order to ensure that the adjusted length of the connecting crossbeam 120 can be stably maintained, a positioning structure 123 is provided on the sleeve 121 to define the relative position between the sleeve 121 and the connecting rod 122. The positioning structure 123 can use a set screw or a latch. When adjusting the relative position of the sleeve 121 and the connecting rod 122, the positioning structure 123 is loosened or removed, and then tightened or installed again after adjustment to ensure the structural stability of the support base 100.

[0050] U-shaped limiting structures 130 are evenly spaced at the top of the two supporting longitudinal beams 110 along the length extension direction. The U-shaped limiting structures 130 on each supporting longitudinal beam 110 are arranged opposite to the U-shaped limiting structures 130 on the adjacent supporting longitudinal beam 110, and each opposite group of U-shaped limiting structures 130 is used to place a stirrup 200.

[0051] like Figure 4 As shown, a clamping structure 140 for clamping the stirrup 200 is provided in the U-shaped limiting structure 130 so that the stirrup 200 is stably placed in the U-shaped limiting structure 130 .

[0052] The clamping structure 140 includes a clamping rod 141 symmetrically arranged on the two side walls of the U-shaped limiting structure 130, the clamping rod 141 extends upward beyond the U-shaped limiting structure 130, the clamping rod 141 is hinged to the U-shaped limiting structure 130, and the U-shaped limiting structure 130 is provided with an elastic component 142 at the upper part of the hinge position, one end of the elastic component 142 is fixedly connected to the U-shaped limiting structure 130, and the other end is fixedly connected to the position of the clamping rod 141 above the U-shaped limiting structure 130; in a normal state, the elastic component 142 tightens the two clamping rods 141 so that the bottom ends of the two clamping rods 141 are close to each other and the top ends are far away from each other, thereby facilitating the placement of the stirrup 200 from top to bottom between the two clamping rods 141. In the process of placing the stirrup 200 between the two clamping rods 141, the two clamping rods 141 will be pushed to rotate to clamp the stirrup 200 from both sides. In this embodiment, the elastic member 142 is a coil spring. The clamping rod 141 in the clamping structure 140 is flexibly rotatable, and the coil spring acts as the elastic member 142 to provide just the right amount of tension. When the stirrups 200 are placed, the stirrups 200 overcome the tension of the coil spring to push the clamping rod 141 apart. Once in place, the coil spring tightens the clamping rod 141, tightly clamping it and effectively preventing displacement.

[0053] like Figure 5 、 Figure 6 As shown, two centering adjustment units 300 are symmetrically provided, and the stirrup buffer rack is used to be arranged between the two centering adjustment units 300 to align all stirrups 200 longitudinally.

[0054] Specifically, each centering adjustment unit 300 includes a support frame 310 and a centering frame 320 .

[0055] The support frame 310 is constructed with a solid steel structure frame, which provides a stable basic support for the entire adjustment process.

[0056] The centering frame 320 is slidably disposed on the top of the support frame 310 , and the centering frames 320 of the two centering adjustment units 300 can move closer to or farther away from each other by sliding along the support frame 310 .

[0057] In this embodiment, a sliding rail 370 is fixedly provided on the top of the support frame 310, and a sliding block 380 that cooperates with the sliding rail 370 is provided at the bottom of the centering frame 320. The centering frame 320 achieves sliding cooperation with the support frame 310 through the cooperation between the sliding block 380 and the sliding rail 370.

[0058] Furthermore, in order to facilitate the sliding of the centering frame 320 along the support frame 310, a driving motor 330 is fixedly installed on the centering frame 320, and a driving gear 340 is fixedly connected to the output shaft of the driving motor 330. A rack 350 that can mesh with the driving gear 340 is fixedly installed on the side of the support frame 310 corresponding to the driving gear 340, so that the driving motor 330 can drive the centering frame 320 to slide back and forth along the support frame 310 by forward and reverse rotation.

[0059] Furthermore, to enhance the support provided by the support frame 310 to the centering frame 320, multiple sets of universal ball joints 360 are fixed to the top of the support frame 310, and the bottom of a portion of the centering frame 320 is mounted on the universal ball joints 360. This allows the centering frame 320 to maintain stability when it deviates significantly from the support frame 310 during sliding, in addition to the cooperation between the sliding rails 370 and the sliding blocks 380.

[0060] An adjustment plate 321 is provided on one side of the centering frame 320 facing the buffering frame. The adjustment plates 321 of the two centering adjustment units 300 jointly define the stirrups 200 from both sides so that the stirrups 200 are aligned.

[0061] Furthermore, the adjustment plate 321 is evenly arranged with grooves 322 for placing stirrups 200 along the length extension direction. The grooves 322 on the push plate are customized according to the standard size of the stirrups 200. The precise control of the depth and width enables the stirrups 200 to fall accurately into the grooves 322 and achieve an ideal alignment effect. In the alignment process, with the limitation of the grooves 322, the stirrups 200 fall into the grooves 322 on both sides during the placement process, which can better ensure the accurate positioning of the stirrups 200.

[0062] Furthermore, support wheels 323 are provided below the adjustment plate 321 to support the bottom of the stirrups 200. Below these wheels 323 is a lifting drive mechanism 324 to drive the wheels 323 upward or downward. In this embodiment, the lifting drive mechanism 324 utilizes a highly responsive hydraulic jack or electric push rod to push the stirrups 200 back and forth from the bottom, enabling dynamic adjustment of the alignment of all stirrups 200. Furthermore, the support wheels 323 serve another purpose: when the centering frame 320 compresses the stirrups, the stirrups can more easily and flexibly move horizontally, thereby facilitating longitudinal alignment of the stirrups.

[0063] Furthermore, a first limiting wheel 325 is provided on the inner side of the centering frame 320. The first limiting wheels 325 on the two centering frames 320 are used to limit the placement position of the stirrup buffer rack from the outside. That is, when the stirrup buffer rack is placed on the two support frames 310, the first limiting wheels 325 on the two centering frames 320 are located on the outside of the two supporting longitudinal beams 110, limiting the placement position of the support base frame 100 from both sides. Specifically, during operation, the two centering frames 320 are relatively close to each other. When the distance between the first limiting wheels 325 on the two centering frames 320 approaches the width of the support base frame 100, the two centering frames 320 stop and the support base frame 100 is placed on the two centering frames 320. At this time, the adjustment plates 321 of the two centering adjustment units 300 jointly limit the placement space for all stirrups 200.

[0064] like Figure 7 As shown, the transport equipment 400 is used to carry the stirrup cache rack and transport it to a set location.

[0065] The transport equipment 400 includes a vehicle body 410 , a lifting mechanism 420 and a placement frame 430 .

[0066] The vehicle body 410 uses a powerful electric flatbed vehicle or RGV trolley, which can quickly shuttle between various processing stations.

[0067] The jacking mechanism 420 is arranged on the top of the vehicle body 410 and uses a hydraulic jacking device with stable performance to accurately control the lifting height of the stirrup cache rack.

[0068] The placement rack 430 is provided on top of the lifting mechanism 420 and is used to place the stirrup cache rack. Second limiting wheels 440 are provided on both sides of the placement rack 430 to ensure that the stirrup cache rack is stably placed on the placement rack 430. The second limiting wheels 440 are used to limit the placement position of the support base 100 from the inner side of the two supporting longitudinal beams 110 and ensure the stability of the stirrup cache rack when moving on the placement rack 430.

[0069] The working principle of the stirrup adjustment device is as follows:

[0070] like Figure 8 As shown, first, the transport equipment 400 carries the stirrup cache rack and moves between the two support frames 310, and the lifting mechanism 420 lifts the stirrup cache rack upward to a height close to the first limiting wheel 325, and then, the centering frames 320 of the two centering adjustment units 300 move in a relatively close direction until the centering frame 320 on one side of the first limiting wheel 325 partially extends under the stirrup cache rack, and the centering frame 320 stops moving when the first limiting wheel 325 contacts the stirrup cache rack from both sides. At this time, the distance between the two adjustment plates 321 is slightly larger than the width of the stirrups, which facilitates the placement of the stirrups. Then, the lifting drive structure 324 is started to lift up to the top of the support wheel 323 and exceed the bottom of the U-shaped limiting structure 130, and then the stirrups 200 are placed in the stirrup buffer rack. At this time, the bottom of the stirrups 200 is directly placed on the support wheel 323 and does not fall completely into the U-shaped limiting structure 130. When all the stirrups are placed, all the stirrups 200 are further adjusted by starting the adjustment plates 321 on both sides to squeeze relative to each other, so that all the stirrups 200 are further aligned longitudinally. Then, the height of the support wheel 323 is lowered again, and all the stirrups 200 fall completely into the bottom of the U-shaped limiting structure 130 at the same time and are clamped, completing the placement of the stirrups 200. Finally, the transportation equipment 400 transports the stirrup buffer rack to the subsequent longitudinal reinforcement threading station. At this point, the caching and alignment of the stirrups 200 are all completed, laying a solid foundation for the subsequent efficient and accurate longitudinal reinforcement threading processing steps.

[0071] In other embodiments of the stirrup buffer adjustment device, three, four or more supporting longitudinal beams may be provided, and the supporting longitudinal beams are arranged longitudinally, and the supporting base frame of the frame structure is formed by the transversely arranged connecting beams.

[0072] In other embodiments of the stirrup slow adjustment device, when three supporting longitudinal beams are provided, U-shaped limiting structures can also be arranged on the three supporting longitudinal beams. At this time, in the transverse direction, each relative group of U-shaped limiting structures is used to place a stirrup.

[0073] An embodiment of the stirrup cache rack in the present invention is as follows: In this embodiment, the technical solution of the stirrup cache rack is the same as that of the stirrup cache rack in the above-mentioned stirrup adjustment device, and will not be repeated here.

[0074] It will be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0075] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
