Description

Technical Field

[0001] This application relates to the field of rebar tying equipment technology, and in particular to a rebar tying equipment for prefabricated assembly construction. Background Technology

[0002] Precast assembly construction technology has been widely used in engineering construction. This technology improves construction efficiency and quality by manufacturing components in factories and assembling them on-site. During the manufacturing process of precast building components, reinforcing bars are laid out in a mesh on a formwork platform. Then, manually hand-held reinforcing bar tying machines are used to tie the intersecting reinforcing bars, or trolley-type automatic reinforcing bar tying equipment is used.

[0003] However, traditional rebar tying machines rely on manual operation, requiring manual placement of support blocks near the tying point to prevent the middle portion of the rebar from collapsing and bending due to gravity during tying. This ensures the stability of the rebar's height during tying, resulting in a large amount of manual labor and affecting the production efficiency of precast building components. Trolley-type rebar tying equipment, on the other hand, needs to move along the rebar mesh during tying. To avoid the influence of the trolley's weight on the rebar, clamps are bolted to both ends of the rebar before tying. The clamps are then used to hold the ends of the rebar against the outer wall of the formwork, limiting the collapse and bending of the middle portion. Therefore, manual fixing of both ends of each rebar is still required, similarly impacting the overall efficiency of the rebar tying operation. Summary of the Invention

[0004] This application proposes a prefabricated assembly-type rebar tying equipment for construction, which has the advantage of tying rebar tying nodes sequentially while providing temporary support, thereby solving the problem of reduced efficiency in the traditional tying operation due to reliance on manual preparation.

[0005] To achieve the above objectives, this application adopts the following technical solution: a prefabricated assembly construction rebar tying device, comprising a vertical moving component and a tying component, wherein the tying component is disposed at the bottom of the vertical moving component, a fixed seat is fixedly connected to one side of the vertical moving component, two fixed plates are fixedly connected to the bottom of the fixed seat, a guide groove is provided on one side of the fixed plate, a moving rod is movably disposed on one side of one of the two fixed plates, a lifting rod is fixedly connected to one side of the moving rod, and a support block is fixedly connected to the bottom end of the lifting rod.

[0006] The bottom of the fixed base is provided with an adjustment mechanism. The adjustment mechanism can drive the moving rod to move along the guide groove according to the specifications of the steel bar, adjust the distance between the moving rod and the fixed base, so that the moving rod drives the lifting rod to move to the bottom of the steel bar and drive the steel bar to rise to the corresponding set height.

[0007] Furthermore, the bottom part of the guide groove is inclined, the top part of the guide groove is vertical, the adjustment mechanism includes a guide rod, the guide rod is slidably sleeved in the guide groove, the moving rod is fixedly connected to the guide rod, a sliding plate is slidably arranged on one side of the fixed plate, the moving rod is slidably engaged with the fixed plate, and a connecting rod is fixedly connected between the two lifting rods.

[0008] Furthermore, the fixed base has limit grooves on both sides, and two positioning rods are slidably arranged inside the limit grooves. The bottom of the positioning rods is fixedly connected to a limit plate, and an adjustment plate is rotatably arranged on the top of the fixed base. Two positioning grooves are opened on both sides of the adjustment plate, and the positioning rods are slidably sleeved in the positioning grooves. Protrusions are fixedly sleeved at the top of the adjustment plate and the bottom of the fixed base.

[0009] Furthermore, the limiting groove is a straight groove and the extension directions of the two limiting grooves are perpendicular to each other. The positioning groove is arc-shaped and the distance from different positions of the positioning groove to the rotation center of the adjusting plate is different. The unidirectional rotation of the adjusting plate relative to the fixed seat can gradually increase the distance from the corresponding positions of the positioning groove and the limiting groove to the rotation center.

[0010] Furthermore, an adjusting rod is slidably sleeved on one side of the fixed base, the adjusting rod has an adjusting groove on its body, a protruding rod is slidably arranged inside the adjusting groove, the protruding rod is fixedly connected to the adjusting plate, and the adjusting rod is slidably sleeved with the adjusting plate.

[0011] Furthermore, the axis of the adjusting rod is collinear with the rotation center line of the adjusting plate relative to the fixed seat, the adjusting groove is a spirally extending arc shape, a movable rod is provided on one side of the bottom of the adjusting rod, a sliding rod is fixedly connected to the bottom end of the movable rod, and a connecting plate is fixedly connected to the bottom end of the movable rod, with the connecting plate and the sliding rod slidably sleeved together.

[0012] Furthermore, the adjustment mechanism also includes a transmission mechanism, which includes a transmission rod that is slidably engaged with a moving rod. A first connecting block is fixedly connected to the top of the transmission rod, and a second connecting block is provided on the top of the first connecting block. The second connecting block is fixedly connected to the moving rod, and a first adjusting screw is rotatably engaged with the second connecting block. The first adjusting screw is threadedly engaged with the first connecting block. One side of the support block is set as an inclined surface, and a return spring is fixedly connected to one side of the bottom of the fixed seat.

[0013] Furthermore, a second adjusting screw is rotatably engaged on one side of the movable rod, and a third connecting block is threaded onto the top of the second adjusting screw. The third connecting block is fixedly connected to the adjusting rod and to the return spring.

[0014] Furthermore, the adjustment mechanism also includes an electric push rod, the movable rod is fixedly connected to the adjustment rod, the support block is configured as a plate with a flat side, the electric push rod is fixedly installed on one side of the fixed base, and the output end of the electric push rod is fixedly connected to the movable rod.

[0015] Furthermore, it also includes a longitudinal moving component, on the top of which is a transverse moving component, which is used to drive the longitudinal moving component to move laterally.

[0016] The beneficial effects of this invention are as follows:

[0017] This application provides a prefabricated assembly-type rebar tying device. During the synchronous descent of the fixed seat and the tying assembly, a moving rod is driven to move, which in turn drives a lifting rod to move until the support block descends to the rated height. As the tying assembly continues to descend, the moving rod is driven by a transmission rod or an electric push rod to move closer to the fixed seat. This causes the moving rod to move along the guide groove, thereby driving the lifting rod to move vertically relative to the fixed seat and simultaneously moving horizontally. This causes the support block to move to the bottom of the rebar to form support and clamp it with the tying assembly. This ensures the quality of rebar tying while improving the overall tying efficiency. Furthermore, the tying of the rebars in close contact with each other helps the tying assembly reduce the excess tying wire.

[0018] This application provides a prefabricated rebar tying device for construction. Simultaneously, the movement of a moving rod raises and lowers the device, driving the synchronous movement and relative raising and lowering of an adjusting rod and a fixed base. This changes the corresponding position of the adjusting groove and the protruding rod. As the tying assembly approaches the rebar, the protruding rod slides along the adjusting groove, driving the adjusting plate to rotate. This changes the corresponding position of the limiting groove and the positioning groove, causing the positioning rod to move the limiting plate closer to each other to a rated distance, thus completing the horizontal limiting of the rebar. This further improves the tying quality and reliability of the rebar tying device. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, as Figures 1-6 A prefabricated rebar tying device for construction includes a longitudinal moving component 1 and a tying component 4. A transverse moving component 2 is mounted on top of the longitudinal moving component 1, and a vertical moving component 3 is mounted on the transverse moving component 2. The tying component 4 is located at the bottom of the vertical moving component 3. All three components are linear guide rail modules. The vertical moving component 3 can also be configured as a multi-axis robotic arm module. The longitudinal moving component 1 drives the transverse moving component 2 longitudinally, the transverse moving component 2 drives the vertical moving component 3 laterally, and the vertical moving component 3 drives the tying component 4 vertically. (See reference...) Figure 2A fixed base 17 is fixedly connected to one side of the vertical moving component 3. Two fixed plates 6 are fixedly connected to the bottom of the fixed base 17. The fixed plates 6 are located on both sides of the node of the steel bar to be tied.

[0030] A guide groove 12 is provided on one side of the fixing plate 6, see reference. Figure 6 The bottom part of the guide groove 12 is inclined, and the top part of the guide groove 12 is vertical. A guide rod 13 is slidably sleeved on the inner side of the guide groove 12. A movable rod 8 is movably arranged on one side of one of the two fixed plates 6. The movable rod 8 is fixedly connected to the guide rod 13. (See reference) Figure 4 A sliding plate 7 is slidably disposed on one side of the fixed plate 6. The sliding plate 7 can slide horizontally relative to the fixed plate 6. The moving rod 8 is slidably engaged with the fixed plate 6. The moving rod 8 can slide vertically relative to the fixed plate 6 while simultaneously driving the sliding plate 7 to move horizontally relative to the fixed plate 6. A lifting rod 9 is slidably connected to one side of the sliding plate 7. The moving rod 8 is fixedly connected to the corresponding lifting rod 9. (See reference) Figure 3 A connecting rod 11 is fixedly connected between the two lifting rods 9. (See reference) Figure 2 The bottom end of the lifting rod 9 is fixedly connected to a support block 10. The support block 10 is used to support the bottom of the two intersecting steel bars. The bottom of the fixed seat 17 is provided with a connecting mechanism, which can drive the moving rod 8 to move vertically to adjust the distance between the moving rod 8 and the fixed seat 17.

[0031] When binding the reinforcing bars, the connecting mechanism drives the moving rod 8 to remain away from the fixed seat 17. At this time, the guide rod 13 is at the bottom of the guide groove 12. The longitudinal moving component 1, together with the transverse moving component 2, drives the vertical moving component 3 to move to the horizontal position of the binding component 4, which corresponds to the horizontal position of the reinforcing bar binding node. The vertical moving component 3 drives the binding component 4 and the fixed seat 17 to descend synchronously. The binding component 4 moves close to the two reinforcing bar binding nodes. At this time, the fixed seat 17 descends, causing the fixed plate 6 to descend. At the same time, the fixed seat 17, together with the connecting mechanism, drives the moving rod 8 to descend synchronously relative to the fixed plate 6. The movement of the moving rod 8, together with the connecting rod 11, drives the two lifting rods 9 to descend relative to the reinforcing bars. The movement of the lifting rods 9 causes the corresponding support blocks 10 to decrease in height. At this time, the support blocks 10 corresponding to the two fixed plates 6 are located on both sides of the bottom of the binding component 4.

[0032] When the binding assembly 4 moves to a position close to the rebar binding node, the vertical moving assembly 3 continues to drive the binding assembly 4 to descend to a position corresponding to the rebar binding node. At this time, the connecting mechanism drives the moving rod 8 to rise relative to the fixed seat 17. The moving rod 8 drives the guide rod 13 to rise relative to the fixed plate 6. The guide rod 13 slides along the guide groove 12. The inclined part of the guide groove 12 drives the relatively moving guide rod 13 to generate a horizontal displacement, so that while the guide rod 13 rises relative to the fixed seat 17, it drives the moving rod 8 to move horizontally relative to the rebar. The moving rod 8 drives the lifting rod 9 to move closer to the rebar, so that the moving rod 8 drives the support block 10 to contact and support the bottom rebar among the two rebars.

[0033] The support points of the support block 10 are located on both sides of the bottom of the rebar binding node, thereby further cooperating with the binding component 4 to complete the vertical clamping of the two rebars. While providing vertical positioning, it enables the two rebars to be bound in a tightly fitted state. On the one hand, it can provide temporary support to ensure the quality of rebar binding, while saving the step of vertically positioning the height of the rebars in advance, thus improving the overall efficiency of rebar binding. On the other hand, by supporting both sides of the rebar binding node with the binding component 4, the two rebars are in a close fit during binding. This allows the binding component 4 to be fitted onto the outside of the rebar binding node with less binding wire allowance. In order to avoid the binding process being too smooth, the binding head generated by twisting the binding wire is smaller, thus saving binding wire.

[0034] Example 2, as Figures 1-6 Based on Embodiment 1, limiting grooves 18 are provided on both sides of the fixing base 17. The limiting grooves 18 are straight grooves and the extension directions of the two limiting grooves 18 are perpendicular to each other. The positions of the limiting grooves 18 correspond to the horizontal positions of the two sides of the rebar binding nodes of the two rebars, respectively. Two positioning rods 25 are slidably arranged on the inner side of the limiting grooves 18. The bottom of the positioning rods 25 is fixedly connected to the limiting plate 26. (See reference...) Figure 5 An adjusting plate 23 is rotatably mounted on the top of the fixed base 17. Two positioning grooves 24 are opened on both sides of the adjusting plate 23. The positioning grooves 24 are paired up and correspond to the positions of the two limiting grooves 18 respectively. The positioning grooves 24 are arc-shaped and the distance from different positions of the positioning grooves 24 to the rotation center of the adjusting plate 23 is different. The positioning rods 25 are slidably sleeved in the positioning grooves 24. When the adjusting plate 23 rotates unidirectionally relative to the fixed base 17, the distance from the corresponding position of the positioning groove 24 and the limiting groove 18 to the rotation center gradually increases or decreases unidirectionally. The distances of the two corresponding positioning grooves 24 to the rotation center change in opposite directions when the adjusting plate 23 rotates unidirectionally, so that the two positioning rods 25 can move closer to each other when the adjusting plate 23 rotates.

[0035] The positioning rod 25 is fixedly fitted with protrusions at the top of the adjusting plate 23 and the bottom of the fixed base 17. The protrusions limit the tilt of the positioning rod 25 relative to the fixed base 17, and the fixed base 17 can drive the protrusions to move vertically, thereby driving the positioning rod 25 to move vertically. An adjusting rod 14 is slidably fitted on one side of the fixed base 17. The axis of the adjusting rod 14 is collinear with the rotation center line of the adjusting plate 23 relative to the fixed base 17. The adjusting rod 14 has an adjusting groove 15 on its body. The adjusting groove 15 is a spirally extending arc shape. A protruding rod 16 is slidably provided on the inner side of 15. The protruding rod 16 is fixedly connected to the adjusting plate 23. The adjusting rod 14 is slidably sleeved with the adjusting plate 23. A movable rod 19 is provided on one side of the bottom of the adjusting rod 14. The adjusting rod 14 can move the movable rod 19 axially. A sliding rod 20 is fixedly connected to the bottom end of the movable rod 19. A connecting plate 21 is fixedly connected to the bottom end of the moving rod 8. The connecting plate 21 is slidably sleeved with the sliding rod 20. When the sliding rod 20 drives the connecting plate 21 to rise or fall, the connecting plate 21 can move horizontally relative to the sliding rod 20.

[0036] During rebar tying, the fixed seat 17 drives the positioning rod 25 to move vertically downwards. The positioning rod 25 moves and drives the limiting plate 26 to descend to both sides of the corresponding rebar. When the connecting mechanism drives the moving rod 8 to rise relative to the fixed seat 17, the moving rod 8, in conjunction with the connecting plate 21, sliding rod 20, and movable rod 19, drives the adjusting rod 14 to rise relative to the fixed seat 17. The adjusting rod 14 rises relative to the adjusting plate 23, causing the adjusting groove 15 to rise relative to the protruding rod 16. The protruding rod 16 corresponds to different positions of the adjusting groove 15. The inner wall of the adjusting groove 15 abuts against the protruding rod 16, causing the protruding rod 16 to move along the adjusting groove 15. As the groove 15 slides, it drives the protruding rod 16 to rotate relative to it. The protruding rod 16 drives the adjusting plate 23 to rotate relative to the fixed seat 17, changing the corresponding position of the positioning groove 24 and the limiting groove 18. The inner wall of the positioning groove 24 abuts against the positioning rod 25, driving the positioning rod 25 to move along the limiting groove 18 and approach the reinforcing bar under the guidance of the limiting groove 18, thus limiting the horizontal position of the reinforcing bar. This not only vertically positions the reinforcing bar, but also horizontally limits the position of one end of the two reinforcing bars, preventing the reinforcing bars from being tied when they are horizontally bent, and further improving the quality of the reinforcing bar tying.

[0037] Example 3, as Figure 2 and Figure 3Based on Embodiment 2, one configuration of the connecting mechanism is as follows: The connecting mechanism is configured as a transmission mechanism 5, which includes a transmission rod 501. The transmission rod 501 is slidably engaged with the moving rod 8. The transmission rod 501 can move vertically relative to the moving rod 8, while the moving rod 8 can drive the transmission rod 501 to move horizontally relative to the fixed plate 6. A first connecting block 502 is fixedly connected to the top of the transmission rod 501. A second connecting block 503 is provided on the top of the first connecting block 502. The second connecting block 503 is fixedly connected to the moving rod 8. The second connecting block 503 is rotatably engaged with an adjusting screw 504. The first adjusting screw 504 can only move relative to the second connecting block 503. When the connecting block 503 rotates, the first adjusting screw 504 is threadedly connected to the first connecting block 502. One side of the support block 10 is set as an inclined surface. The second adjusting screw 506 is rotatably engaged on one side of the movable rod 19. The second adjusting screw 506 can rotate relative to the movable rod 19 and drive the movable rod 19 to rise and fall. The top of the second adjusting screw 506 is threadedly connected to the third connecting block 505. The third connecting block 505 is fixedly connected to the adjusting rod 14. The top of the third connecting block 505 is fixedly connected to the return spring 507. One end of the return spring 507 is fixedly connected to the fixed seat 17. The return spring 507 is used to push the third connecting block 505 away from the fixed seat 17.

[0038] The return spring 507 provides elastic force, which drives the moving rod 8 to remain in its original position. When the fixed seat 17 descends, the fixed seat 17 moves through the elastic third connecting block 505. The third connecting block 505 drives the adjusting rod 14 to descend, and at the same time, it works with the second adjusting screw 506 to drive the movable rod 19 to descend. The movable rod 19 drives the moving rod 8 to descend. The moving rod 8 works with the second connecting block 503, the first adjusting screw 504 and the first connecting block 502 to drive the transmission rod 501 to descend. The bottom of the transmission rod 501 abuts against the bottom of the mold table, restricting the transmission rod 501 from moving further. At this time, the binding assembly 4 continues to descend, the fixed seat 17 descends, and the transmission rod 501 drives the moving rod 8 to move closer to the fixed seat 17. At the same time, the moving rod 8 drives the support block 10 to stop descending and drive the support block 10 to move closer to the reinforcing bar. The inclined surface of the support block 10 abuts against the reinforcing bar and drives the reinforcing bar to rise. The top surface of the support block 10 supports the reinforcing bar, completing the vertical positioning of the reinforcing bar.

[0039] Simultaneously, the moving rod 8 drives the third connecting block 505 to move closer to the fixed seat 17, which in turn drives the two corresponding limiting plates 26 to move closer to each other to horizontally position the reinforcing bars. The first adjusting screw 504 is used to adjust the initial extension distance of the transmission rod 501. When the transmission rod 501 corresponds to reinforcing bars of different heights, it moves closer to the rated distance relative to the fixed seat 17, so that the reinforcing bar binding equipment can adapt to binding reinforcing bars of different heights. The second adjusting screw 506 is used to adjust the extension distance of the adjusting rod 14 relative to the fixed seat 17, and to adjust the initial corresponding position of the adjusting groove 15 relative to the protruding rod 16. It also adjusts the initial spacing of the two corresponding limiting plates 26. When the reinforcing bar specifications change, the corresponding initial spacing is adjusted, so that the reinforcing bar binding equipment can adapt to reinforcing bars of different diameters, further improving the adaptability of the reinforcing bar binding equipment.

[0040] Example 4, as Figures 4-7 Unlike the transmission mechanism 5 in Embodiment 3, another way of setting the connecting mechanism is as follows: the connecting mechanism is set as an electric push rod 22, and the movable rod 19 is fixedly connected to the adjusting rod 14. The support block 10 is set as a plate with a flat side. The electric push rod 22 is fixedly set on one side of the fixed seat 17, and the output end of the electric push rod 22 is fixedly connected to the movable rod 19.

[0041] When binding rebar, the fixed seat 17 descends, causing the electric push rod 22 to descend. The electric push rod 22, maintaining its extended length, drives the movable rod 19 to descend. The movable rod 19 drives the adjusting rod 14 to descend synchronously relative to the fixed seat 17. The movable rod 19 synchronously drives the moving rod 8 to descend until the transmission belt support block 10 descends to the bottom of the rebar at the rated distance. At this point, the electric push rod 22 drives the movable rod 19 to rise relative to the fixed seat 17, and the distance it rises relative to the bottom of the formwork is greater than the distance the fixed seat 17 continues to descend. This allows the support block 10 to rise relative to the rebar after moving horizontally to the bottom of the rebar, thereby increasing the support range for rebars that have collapsed to different heights and further improving the reliability of the rebar binding equipment.

[0042] Until the electric push rod 22 retracts to its rated length, the electric push rod 22 determines whether the binding assembly 4 and the support block 10 are clamped in place through servo feedback. When vertically supporting and clamping steel bars of different diameters, the distance between the support block 10 and the binding assembly 4 is different. According to the different retraction values ​​of the servo feedback, the electric push rod 22 adjusts the circumferential change distance of the adjustment groove 15 to match the change in steel bar diameter. The electric push rod 22 drives the adjustment rod 14 to move a corresponding distance relative to the fixed seat 17 according to the steel bar diameter, so that the spacing of the limit plate 26 matches the corresponding steel bar, further improving the flexibility and reliability of the steel bar binding equipment.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
