Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an automated positioning and assembly mechanism for steel reinforcement cage stirrups. Background Technology

[0002] In modern reinforced concrete engineering, traditional column cage reinforcement is still tied on-site. However, with the promotion of fully automated equipment for steel reinforcement processing, column cage reinforcement skeletons are gradually moving towards factory prefabrication, with automated machine tying replacing manual on-site operations. The main process of tying column cage reinforcement skeletons includes fixing stirrups, threading longitudinal bars, and automatic tying. This process generally requires tooling to position and clamp the stirrups of the reinforcement cage, and subsequent operations are carried out on this tooling.

[0003] Existing rebar cage tying platforms typically use a fixed beam with two rows of tying supports on either side. Tying components are spaced out on the fixed beam for tying stirrups. This method can position a small number of rebar cages of a fixed size, but it cannot position rebar cages of varying sizes. Furthermore, the size of the rebar groove for fixing the stirrups is fixed, making it impossible to clamp the stirrups. In addition, while the positioning fixture can move in the front-back and left-right directions, it lacks a fixing measure in the height direction of the stirrups, making it impossible to fix rebar cages with large stirrup heights. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides an automated positioning and assembly mechanism for stirrups in a steel reinforcement cage, applicable to stirrups of different specifications, achieving automatic positioning and clamping of stirrups.

[0005] To achieve the above objectives, the present invention provides an automated positioning and assembly mechanism for stirrups in a reinforcing steel cage, comprising:

[0016] Preferably, the fixed combination clamp assembly includes a second bracket fixedly mounted on the chassis at one end along the length direction away from the indicator light assembly, a second combination clamp fixedly mounted on the top of the second bracket along the height direction for supporting the bottom of the stirrup, and a third combination clamp vertically mounted above the second bracket for supporting the side of the stirrup.

[0017] Preferably, the third combination clamp is provided in multiple sets along the height direction of the second bracket, and the multiple sets of the third combination clamp and the second combination clamp are provided with multiple second slots spaced apart from the first slot along the length direction, and the opening direction of the second slot on the second combination clamp is upward, and the opening direction of the second slot on the third combination clamp is towards the side of the stirrup.

[0018] Preferably, the lifting longitudinal track includes a first track body that is movably and liftably installed on the transverse track along the length direction of the external track, a cam lifting base installed at the bottom of the first track body, and a cam rotatably installed on the cam lifting base near the first track body.

[0040] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] The technical problem to be solved by this invention is that existing rebar cage binding platforms can only position a small number of rebar cages of a certain specification, but cannot position rebar cages of different specifications with stepless variation. At the same time, the size of the rebar groove for fixing the stirrups is fixed, which cannot achieve the clamping function of the stirrups. Furthermore, there are no fixing measures in the height direction of the stirrups, which cannot fix rebar cages with large stirrup heights. The invention provides an automated positioning and assembly mechanism for rebar cage stirrups, which can automatically position and clamp stirrups of different specifications, achieve stepless variation, and is adjustable in both the horizontal and vertical directions.

[0042] Please see Figures 1 to 12 As shown, this invention provides an automated positioning and assembly mechanism for stirrups in a steel reinforcement cage, including a transfer base 1, an external track 2, a stirrup fixing trolley 3, and an indicator light assembly 4. The stirrup fixing trolley 3 is movably mounted on the transfer base 1. The transfer base 1 includes a horizontally arranged transverse track 11 and a vertically mounted lifting longitudinal track 12 for transporting the stirrup fixing trolley 3 to the external track 2. The external track 2 is located on one side of the transfer base 1 and aligned with the lifting longitudinal track 12. The stirrup fixing trolley 3 includes a chassis 31 slidably mounted on the transverse track 11, a fixed combination clamp assembly 35 fixedly mounted at one end of the transverse track 11 along its length, and a movable combination clamp assembly 34 driven by a drive motor 345 and movably mounted on one side relative to the fixed combination clamp assembly 35 along the length of the transverse track 11 for clamping the stirrups 5. It should be noted that multiple stirrup fixing trolleys 3 can be provided and circulate in a loop.

[0043] Please see Figure 1 , Figures 8 to 10 As shown, in this embodiment, the transfer base 1 includes two transverse tracks 11, the ends of which are fixedly connected by a first connecting rod 13. Two lifting longitudinal tracks 12 are also provided, vertically installed between the two transverse tracks 11 and located in the middle of the transfer base 1. Preferably, the lifting longitudinal track 12 includes a first track body 121 movably and vertically mounted on the transverse track 11 along the length direction of the outer track 2, a cam lifting base 122 mounted on the bottom of the first track body 121, and a cam 125 rotatably mounted on the cam lifting base 122 near the first track body 121. A camshaft 123 is coaxially fixedly mounted on the cam 125, and the camshaft 123 is fixedly connected to the first track body 121. Multiple first conveying wheels 124 are spaced apart on the first track body 121 for the stirrup fixing trolley 3 to move along the length direction of the lifting longitudinal track 12.

[0044] Furthermore, such as Figure 10As shown, in this embodiment, a cylinder 126 is installed at the tail of the first track body 121. The cylinder 126 can pull the first track body 121 to move back and forth slightly along the length of the lifting longitudinal track 12, thereby driving the camshaft fixed on the first track body 121 to move back and forth along the cam lifting base 122 for lifting the longitudinal track 12. When the cam lifting base 122 is at its high point, the lifting longitudinal track 12 is raised, the first conveying wheel 124 is higher than the transverse track 11, and the hoop fixing trolley 3 can move longitudinally. When the cam lifting base 122 is at its low point, the lifting longitudinal track 12 is lowered, the first conveying wheel 124 is lower than the transverse track 11, and the hoop fixing trolley 3 can move laterally.

[0045] Please see Figure 1 and Figure 11 As shown, the external track 2 includes a second track body 21 aligned with the first track body 121 along its length and a plurality of second conveying wheels 22 spaced apart on the second track body 21. In this embodiment, the external track 2 has two second track bodies 121 corresponding to the lifting longitudinal track 12. Correspondingly, there are also two rows of second conveying wheels 22. The height of the second conveying wheels 22 is consistent with the height of the first conveying wheels 124 after the first track body 121 is raised, so as to ensure that the stirrup fixing trolley 3 can be moved onto the external track 2 to perform the process of threading longitudinal bars and binding.

[0046] Please see Figure 1 and Figure 12 As shown, the indicator light assembly 4 includes multiple indicator light brackets 41 fixedly installed on the side of the transfer base 1 and multiple indicator lights 42 installed at intervals corresponding to the placement positions of the stirrups 5. In this embodiment, the indicator lights 42 are evenly arranged at intervals of 50mm. When the stirrups 5 are placed, the indicator lights 42 are lit according to the specifications of the steel cage. The position of the stirrups 5 is the same as that of the indicator lights 42. It should be noted that in this embodiment, the stirrups 5 are placed when the stirrup fixing trolley 3 is close to the side of the indicator lights 42, and the material is unloaded when it is away from the side of the indicator lights 42.

[0047] Please see Figures 2 to 6 As shown, wheels 32 are mounted on the underside of the chassis 31 for sliding on the transverse track 11. Multiple slide rails 33 are fixedly mounted on the side of the chassis 31 parallel to the transverse track 11 for the movable combined clamp assembly 34 to move laterally.

[0048] Furthermore, the movable combination clamp assembly 34 includes multiple sliders 341 correspondingly slidably disposed on the slide rail 33, a first bracket 342 fixedly installed on one side of the multiple sliders 341 relative to the slide rail 33, and a support bar 343 fixedly installed on the top of the first bracket 342 for supporting the bottom of the stirrup 5. A first combination clamp 344 for clamping the side of the stirrup 5 is movably mounted on the top of the first bracket 342 above the support bar 343. In this embodiment, the first combination clamp 344 mainly serves as a directional support, connected to the first bracket 342 via a rack 348, and can move up and down via the rack 348. Preferably, a drive motor 345 is fixedly installed on the first bracket 342, and the multiple sliders 341 are connected via a drive shaft 346, which is coaxially connected to the power output end of the drive motor 345.

[0049] Furthermore, the first combination clamp 344 includes a clamping body 3441 that is vertically mounted on the top of the first bracket 342. A central groove is provided on the clamping body 3441 along its length. A movable clamp 3442 is slidably mounted in the central groove along the length of the clamping body 3441. The clamping body 3441, the movable clamp 3442, and the support bar 343 are all provided with multiple first slots 3443 that are spaced apart and used to place the stirrups 5, corresponding to multiple indicator lights 42. In this embodiment, the first slots 3443 are evenly spaced at 50mm intervals. A second cylinder 347 is installed at one end of the movable clamp 3442 along its length to drive the movable clamp 3442 to slide along the length of the clamping body 3441. The second cylinder 347 drives the movable clamp 3442 to slide left and right along the length of the clamping body 3441 until the movable clamp 3442 is misaligned with the first slots 3443 on the clamping body 3441, thereby clamping and fixing the stirrups 5.

[0050] Please see Figure 1 and Figure 7As shown, the fixed combination clamp assembly 35 includes a second bracket 351 fixedly mounted on the chassis 31 at one end along the length direction away from the indicator light assembly 4, a second combination clamp 352 fixedly mounted on the top of the second bracket 351 along the height direction and used to support the bottom of the stirrup 5, and a third combination clamp 353 vertically mounted above the second bracket 351 and used to support the side of the stirrup 5. Preferably, the third combination clamp 353 is provided in multiple sets along the height direction of the second bracket 351. In this embodiment, there are two sets. Both sets of the third combination clamp 353 and the second combination clamp 352 are provided with multiple second slots 354 spaced apart from the first slots 3443. The second slots 354 on the second combination clamp 352 open upwards as vertical support, while the second slots on the third combination clamp 353 open towards the side of the stirrup 5, mainly used to support the side of the higher stirrup 5. It should be noted that in this embodiment, the two sets of third combination clamps 353 are connected to the second bracket 351 through rack 2 355, so that they can move in the vertical direction.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
