Description

Technical Field

[0001] This invention relates to the field of positioning device technology, specifically a binding auxiliary positioning device that is adaptable to the adjustable spacing of multiple specifications of steel bars. Background Technology

[0002] In the construction of concrete structures such as bridges and buildings, the binding of reinforcing cages is one of the core procedures, directly affecting the load-bearing capacity and durability of the components. Traditional methods of binding reinforcing bars usually rely on manual positioning and binding of each bar individually, which suffers from low efficiency, poor accuracy, and high labor intensity. With the promotion of prefabricated structures such as precast beams and columns, reinforcing bar binding jigs (or positioning devices) have emerged, enabling the simultaneous positioning and support of multiple reinforcing bars, significantly improving construction efficiency and forming quality.

[0003] In the application of rebar binding jigs, the position of the positioning groove is fixed to statically position the rebar. Although it can clamp and fix rebars of different thicknesses, the position of the rebar cannot move. This results in the need for repeated disassembly and reassembly or manual movement of the rebar when welding multiple stirrups (transverse reinforcing bars).

[0004] Existing technologies have improved rebar tying frames. For example, a patent document (authorization announcement number CN222371898U) discloses a beam and slab rebar tying frame, which includes an L-shaped bracket, an outer channel steel, an inner channel steel, a lower positioning plate, an upper positioning plate, and a clamping assembly. The inner channel steel and the outer channel steel have multiple positioning grooves on their opposite sides. The clamping assembly includes a clamping plate that slides on the inner channel steel. The clamping plate has clamping grooves corresponding to the positioning grooves, and the sliding of the clamping plate produces a misaligned clamping effect.

[0005] Taking the aforementioned rebar tying jig as an example, during the application of the rebar tying jig, the position of the positioning groove is fixed, and it is impossible to adjust the spacing between the rebars in real time according to the design requirements of the rebar cage. It is difficult to adapt to the forming requirements of rebar cages with multiple specifications and variable spacing. Rebars of different thicknesses are clamped by static positioning of the rebars. During the overall forming process of the rebar cage, it is necessary to install and weld the stirrups (transverse reinforcing bars) between multiple rebars. In this process, the fixation of the rebar tying jig actually affects the construction, requiring repeated disassembly and reassembly or manual movement of the rebars, which is cumbersome and inefficient. Summary of the Invention

The external threaded rod one is threaded through the reversing roller one.

[0012] Preferably, the guide block inserted on the rear guide rail has an internal threaded connection to an external threaded rod, one end of which is fixedly connected to a wire rope on the same side.

[0013] Preferably, the positioning structure includes an inner ring, an annular box is fixedly installed on the outer side of the inner ring, and flat needle roller bearings are fixedly installed on both sides of the annular box. Two mounting brackets are fixedly connected between the outer rings of the two flat needle roller bearings. The two mounting brackets on the right side are fixedly connected to the mounting box, and multiple support rollers are fixedly connected to the bottom of the two mounting brackets on the left side. The support rollers are located on the top of the guide rail on the same side.

[0014] Preferably, a transmission gear one is fixedly installed on the outer side of the annular box, and an outer support frame is provided on the outer side of the transmission gear one.

The transmission gear two meshes with the transmission gear one. The gearbox and the drive motor are both fixedly installed on one of the mounting frames on the left side. The output end of the drive motor is fixedly connected to the input end of the gearbox, and the output end of the gearbox is fixedly connected to the adjacent transmission short shaft. A brake two is sleeved on the outer side of each of the two transmission short shafts, and the outer wall of the brake two is fixedly connected to the adjacent mounting frame.

[0015] Preferably, a partition ring is fixedly installed inside the annular box, and a hydraulic cylinder is fixedly inserted through the partition ring. The bottom end of the hydraulic cylinder passes through the inner wall and inner ring of the annular box in sequence. A support short pipe is fixedly connected to the bottom end of the hydraulic cylinder. A hydraulic expansion component is fixedly installed inside the support short pipe. A flow guide is fixedly connected to the outside of the support short pipe. The flow guide passes through the inner ring, the annular box, and the partition ring. Two telescopic pipes and two sealing pipes are sleeved on the outside of the flow guide. The telescopic pipes are fixedly installed between the flow guide and the partition ring, and the sealing pipes are fixedly installed between the partition ring and the inner wall of the annular box.

[0016] Preferably, four supporting bends and multiple reinforcing bars are provided between the two positioning structures. Rubber sleeves are fixedly installed on the outer side of each of the four supporting bends, and one end of each supporting bend is fixedly connected to the outer side of the adjacent supporting short pipe on the right.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. When using this application, multiple steel bar pre-fixing operations are completed sequentially. Multiple supporting short pipes in the two positioning structures are arranged proportionally on a circular trajectory, and multiple steel bars form a circular channel. The supporting short pipes with four supporting bent rods installed in the right positioning structure are reference pieces. The hydraulic cylinders that control the installation of the reference pieces, as well as the hydraulic cylinders installed on the supporting short pipes at corresponding positions between two adjacent reference pieces, work. The four reference pieces and multiple supporting short pipes move to form positioning channels with different inner diameters. The hydraulic cylinders at the corresponding positions in the left positioning structure work, so that the internal deformation of the two positioning structures can be controlled to create positioning channels for pre-fixing steel bars according to the required number of steel bars to be tied, thus meeting the needs of tying steel cages composed of steel bars with different inner diameters and different numbers of steel bars.

[0018] 2. When using this application, if it is necessary to tie a square steel cage, control the working stroke of the hydraulic cylinder at the corresponding position inside the positioning structure, and form a square positioning channel with a corresponding number of support short pipes. During this process, control the four reference pieces to be located at the corner of the side wall of the square steel cage. At this time, square support stirrups can be installed on the outside of the support frame composed of four support bent rods. The corner of the support stirrups is aligned with the corner of the steel cage after it is formed, and the side wall of the support stirrups contacts the multiple steel bars that make up the steel cage.

[0019] 3. When this application is used, the cooperation between the two positioning structures and the support structure directly completes the positioning and support work on multiple steel bars in space. Moreover, the positioning and installation of multiple stirrups are completed first, which can quickly and conveniently complete the positioning and welding work between multiple stirrups and multiple steel bars. During the movement of multiple steel bars, the stirrups act as support members between multiple steel bars, preventing the middle of the steel bars from deforming due to lack of support, and preventing deformation at the contact position between the steel bars and the positioning structure from causing movement jamming and a lot of wear, thereby reducing the time cost required for positioning and supporting multiple steel bars and positioning and welding multiple stirrups.

[0022] 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.

[0023] Example: Figures 1-13 As shown, the present invention provides an adjustable binding auxiliary positioning device for rebar spacing of various specifications, including a support structure 1 and two positioning structures 2. The support structure 1 includes a mounting box 11 and two guide rails 13. The positioning structure 2 on the right is installed on the top of the mounting box 11. Guide blocks 9 are inserted on both guide rails 13. Both guide blocks 9 are fixedly connected to the positioning structure 2 on the left. A pulling component is installed between the mounting box 11 and the two guide blocks 9. A gearbox 3 and a drive motor 4 are installed on the positioning structure 2 on the left.

[0024] Specifically, such as Figure 1 and Figure 2 Each of the two guide rails 13 has a guide rail 12 on the side near the mounting box 11. The end of the guide rail 12 away from the mounting box 11 has two insertion slots 15. One end of the insertion plate 14 inside the insertion slot 15 is fixedly connected to the adjacent guide rail 13. The mounting box 11 has four insertion slots 17 on one side. The insertion plate 16 inside each insertion slot 17 is fixedly connected to the adjacent guide rail 12. Two insertion plates 16 are fixedly installed on each guide rail 12. The insertion plates 16 can be inserted into the insertion slot 15, and the insertion plates 14 can be inserted into the insertion slot 17.

[0025] Therefore, two or more guide rails 12 can be assembled between the mounting box 11 and the guide rail 13, and the overall length of the support structure 1 can be adjusted so that the movement stroke of the left positioning structure 2, which is supported and limited by the supported structure 1, is controlled to meet the needs of binding steel bars of different lengths. The support structure 1 can be disassembled after use, reducing the difficulty of handling and using the support structure 1.

[0026] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The dual-axis forward and reverse motor 117 in the pulling assembly is fixedly installed inside the mounting box 11. Both output ends of the dual-axis forward and reverse motor 117 are fixedly connected to the transmission horizontal shaft 118. The outer wall of the brake 119 sleeved on the outside of the transmission horizontal shaft 118 is fixedly connected to the mounting box 11. The operation of the brake 119 controls the transmission horizontal shaft 118 to brake it, thus restricting its rotation. Both sides of the inside of the mounting box 11 are fixedly connected to the gearbox 116. One end of the winding rack 115, which is fixedly connected to the input end of the gearbox 116, is rotatably connected to the mounting box 11. The winding rack 115 can rotate inside the mounting box 11. One end of the transmission horizontal shaft 118 is fixedly connected to the adjacent input end of the gearbox 116. When the transmission horizontal shaft 118 is braked, the input end of the gearbox 116 is braked, the output end of the gearbox 116, which achieves transmission through the gear structure, is braked, and the winding rack 115 is braked.

[0027] Two wire ropes 112 are fixedly installed on the outer sides of the two winding frames 115. Two reversing rollers 114 and two reversing rollers 113 are provided on the outer sides of the two wire ropes 112. The reversing rollers 114 and 113 are fixedly connected to the inner wall of the mounting box 11. The two wire ropes 112 are threaded on the mounting box 11. The two reversing rollers 113 and one reversing roller 114 change the direction of the wire ropes 112 to avoid friction between the wire ropes 112 and the mounting box 111 after bending. The winding frames 115 can also smoothly wind and unwind the wire ropes 112. One end of each wire rope 112 extends into the two guide rails 13.

[0028] When the dual-shaft forward and reverse motor 117 is working, the two gearboxes 116 are turned downwards, the two winding frames 115 rotate in opposite directions, one wire rope 112 is wound up, and the other wire rope 112 is unwound. The dual-shaft forward and reverse motor 117 is controlled to work in the forward or reverse direction, so that the front wire rope 112 is wound up or the rear wire rope 112 is wound up.

[0029] A connector plate 3 18 is inserted at the end of the front guide rail 2 13 away from the mounting box 11. The connector plate 3 18 is connected to the mounting box 11 by bolts. The connector plate 3 18 is detachable. A reversing roller 19 is fixedly installed on one side of the connector plate 3 18 inside the guide rail 2 13. One end of the front wire rope 112 passes through the inside of the guide block 9 and the reversing roller 19. The external threaded rod 110 rotatably connected to one end of the front wire rope 112 is threaded onto the front guide block 9. The reversing roller 19 reverses the direction of the connection between the wire rope 112 and the guide block 9. Under the action of the reversing roller 19, the force generated by the winding of the front wire rope 112 causes the front guide block 9 to move to the right.

[0030] The guide block 9 inserted on the rear guide rail 2 13 has an internal threaded connection to an external threaded rod 2 111. One end of the external threaded rod 2 111 is fixedly connected to the steel wire rope 112 on the same side. The force of the rear steel wire rope 112 being wound causes the rear guide block 9 to move to the right.

[0031] Therefore, by controlling the operation of the pulling component, the dual-axis forward and reverse motor 117 rotates forward or reverses, causing the front wire rope 112 to be wound up or the rear wire rope 112 to be wound up. The front guide block 9 moves to the right or the rear guide block 9 moves to the left, causing the left-side positioning structure 2 fixed between the two guide blocks 9 to move to the right or left.

[0032] Specifically, such as Figure 1 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12In the positioning structure 2, an annular box 21 is fixedly installed on the outer side of the inner ring 29. Flat needle roller bearings 23 are fixedly installed on both sides of the annular box 21. Two mounting brackets 24 are fixedly connected between the outer rings of the two flat needle roller bearings 23. The two mounting brackets 24 on the right side are fixedly connected to the mounting box 11. The annular box 21 and the inner ring 29 can rotate. Multiple support rollers 8 are fixedly connected to the bottom of the two mounting brackets 24 on the left side. The support rollers 8 are set on the top of the guide rail 13 on the same side. The multiple support rollers 8 support the left positioning structure 2 that needs to move, reducing the resistance of the left positioning structure 2 to move left and right. Under the guidance of the guide block 9 and the support structure 1, the left positioning structure 2 moves left and right stably.

[0033] A transmission gear 25 is fixedly installed on the outside of the annular box 21. An outer support frame 22 is provided on the outside of the transmission gear 25. The outer support frame 22 is rotatably connected to the annular box 21 and is fixedly connected to the mounting frame 24. The mounting frame 24 supports the annular box 21 through the outer support frame 22, reducing the stress on the flat needle roller bearing 23 and ensuring the stability of the annular box 21 during operation.

[0034] A transmission gear 26 is fixedly installed on the outer side of the short transmission shaft 27 that rotatably passes through the outer support frame 22. The transmission gear 26 meshes with the transmission gear 25. The short transmission shaft 27 drives the annular box 21 to rotate through the transmission gear 26 and the transmission gear 25. The gearbox 3 and the drive motor 4 are both fixedly installed on a mounting bracket 24 on the left side. The output end of the drive motor 4 is fixedly connected to the input end of the gearbox 3. The output end of the gearbox 3 is fixedly connected to the adjacent short transmission shaft 27 to control the operation of the drive motor 4. The drive motor 4 drives the annular box 21 to rotate through the gearbox 3, the short transmission shaft 27, the transmission gear 26 and the transmission gear 25.

[0035] Brake 28 is fitted on the outer side of each of the two short transmission shafts 27. The outer wall of brake 28 is fixedly connected to the adjacent mounting bracket 24. The operation of brake 28 is controlled to brake the short transmission shafts 27. Since the short transmission shafts 27 and the annular box 21 are driven by a gear structure, the annular box 21 is braked synchronously. The two brakes 28 are normally in working state. The annular box 21 in the two positioning structures 2 is limited to rotation. The relative position between the two annular boxes 21 remains unchanged. The relative position between the multiple supporting short tubes 211 in the two annular boxes 21 remains unchanged.

[0036] Therefore, by controlling the operation of the gearbox 3, the annular box 21 in the left positioning structure 2 can be rotated.

[0037] A partition ring 213 fixedly installed inside the annular box 21 divides the interior of the annular box 21 into an outer pressurization chamber and an inner buffer chamber. A hydraulic cylinder 210 is fixedly installed on the partition ring 213. The bottom end of the hydraulic cylinder 210 passes through the inner wall of the annular box 21 and the inner ring 29 in sequence. A hydraulic expansion component 212 is fixedly installed inside the support short pipe 211 fixedly connected to the piston end of the hydraulic cylinder 210. The hydraulic expansion component 212 and the distance between the hydraulic cylinder 210 and the axis of the inner ring 29 are controlled.

[0038] The guide frame 218, which is fixedly connected to the outside of the supporting short pipe 211, is roughly U-shaped. The guide frame 218 passes through the inner ring 29, the annular box 21, and the partition ring 213. The guide frame 218 is arranged parallel to the hydraulic cylinder 210. The guide frame 218 guides the movement of the hydraulic expansion member 212, and the top of the guide frame 218 is connected to the inside of the pressure chamber of the annular box 21. The hydraulic expansion member 212 is connected to the pressure chamber through the guide frame 218.

[0039] Two telescopic tubes 219 and two sealing tubes 220 are fitted on the outside of the flow guide 218. The telescopic tubes 219 are fixedly installed between the flow guide 218 and the partition ring 213 and can extend and retract. The sealing tubes 220 are fixedly installed between the partition ring 213 and the inner wall of the annular box 21. Through the cooperation of the telescopic tubes 219 and the sealing tubes 220, the liquid inside the annular box 21 will not leak through the gap between the flow guide 218 and the annular box 21. A booster pump 214 and a solenoid valve 216 are fixedly installed inside the annular box 21. A first flow guide tube 215 is fixedly connected between the water inlet of the booster pump 214 and the partition ring 213. A second flow guide tube 217 is fixedly connected between the water outlet of the solenoid valve 216 and the partition ring 213. After the booster pump 214 is controlled to work, it draws the liquid inside the buffer chamber and delivers it to the booster chamber. The hydraulic pressure inside the booster chamber increases, the hydraulic pressure inside the flow guide 218 and the hydraulic expansion component 212 increases, and the hydraulic expansion component 212 expands.

[0040] Specifically, such as Figure 1 and Figure 13 Four support rods 5 and multiple stirrups 7 are provided between the two positioning structures 2. Rubber sleeves 6 are fixedly installed on the outside of the four support rods 5. The right end of the support rod 5 is fixedly connected to the outside of the adjacent support short pipe 211 on the right side. The four support rods 5 form a support frame, and the multiple stirrups 7 are sequentially sleeved on the outside of the support frame.

[0041] In summary, the binding auxiliary positioning device consists of a support structure 1, two positioning structures 2, a gearbox 3, a drive motor 4, multiple support rods 5, multiple support rollers 8, and two guide blocks 9. The operation of the binding auxiliary positioning device is controlled by a human-machine interface device, which is an existing technology and will not be elaborated here.

[0042] The working principle of the binding auxiliary positioning device is as follows: First, multiple reinforcing bars 7 are sequentially fitted onto the outside of the support frame. Then, the left end of the reinforcing bar is passed through the hydraulic expansion member 212 in the right positioning structure 2, and then the left end of the reinforcing bar passes through the hydraulic expansion member 212 in the left positioning structure 2, completing one reinforcing bar pre-fixing operation. Multiple reinforcing bar pre-fixing operations are completed sequentially. Multiple supporting short pipes 211 in the two positioning structures 2 are arranged proportionally on a circular trajectory, and multiple reinforcing bars form a circular channel. The supporting short pipes 211 with four supporting bent rods 5 installed in the right positioning structure 2 serve as reference components. The hydraulic cylinders 210 that control the installation of the reference components, as well as the hydraulic cylinders 210 installed in the corresponding positions of the supporting short pipes 211 between two adjacent reference components, work. The four reference components and multiple supporting short pipes 211 move to form positioning channels with different inner diameters. The hydraulic cylinders 210 at the corresponding positions in the left positioning structure 2 work, so that the internal deformation of the two positioning structures 2 can be controlled to create positioning channels for pre-fixing the reinforcing bars according to the required number of reinforcing bars to be tied, meeting the binding needs of reinforcing cages composed of reinforcing bars with different inner diameters and different numbers of reinforcing bars.

[0043] When it is necessary to tie a square steel cage, the working stroke of the hydraulic cylinder 210 at the corresponding position inside the positioning structure 2 is controlled. The corresponding number of support short pipes 211 form a square positioning channel. During this process, the four reference pieces are controlled to be located at the corner of the side wall of the square steel cage. At this time, square support stirrups 7 can be installed on the outside of the support frame composed of four support bent rods 5. The corner of the support stirrup 7 is aligned with the corner of the steel cage after it is formed. The side wall of the support stirrup 7 is in contact with multiple steel bars that make up the steel cage.

[0044] Subsequently, the two booster pumps 214 in the two positioning structures 2 are controlled to work, and the hydraulic expansion components 212 expand and wrap around the outside of the steel bars. During this process, the hydraulic pressure inside the right hydraulic expansion component 212 is low, and the multiple hydraulic expansion components 212 on the right support the steel bars but do not affect the left and right movement of the steel bars. The hydraulic pressure inside the left hydraulic expansion component 212 is high, and the multiple hydraulic expansion components 212 on the left clamp and fix the steel bars. At this time, the movement of the left positioning structure 2 drives the multiple steel bars to move synchronously.

[0045] Workers weld the leftmost stirrup 7 to the spaces between multiple reinforcing bars. Then, after controlling the pulling component to work for a period of time, the work is paused, causing the left positioning structure 2 to move to the left a certain distance. The stirrup 7 welded between the multiple reinforcing bars moves to the left a certain distance and then stops moving. Workers then weld the second stirrup 7 on the left to the spaces between multiple reinforcing bars, completing one round of reinforcing cage welding. Multiple rounds of reinforcing cage welding are performed, welding multiple stirrup 7 to the spaces between multiple reinforcing bars, completing the welding of multiple stirrup 7 inside the reinforcing cage.

[0046] By cooperating with the two positioning structures 2 and the support structure 1, the positioning and support work of multiple steel bars in space can be directly completed. After the positioning and installation of multiple stirrups 7 are completed first, the positioning and welding work of multiple stirrups 7 and multiple steel bars can be completed quickly and conveniently. During the movement of multiple steel bars, the stirrups 7 act as support members between multiple steel bars, preventing the middle of the steel bars from deforming due to lack of support, and preventing deformation at the contact point between the steel bars and the positioning structure 2 from causing movement jamming and a lot of wear. This reduces the time cost required for positioning and supporting multiple steel bars and positioning and welding multiple stirrups 7, and reduces the number of steps required for staff to participate in.

[0047] After the multiple stirrups 7 are welded to the multiple reinforcing bars, the two brakes 28 are stopped, the short transmission shaft 27 is de-braked, and the annular box 21 can rotate. At this time, the drive motor 4 is controlled to work, the annular box 21 on the left rotates, and the multiple reinforcing bars supported by the multiple stirrups 7 rotate, which meets the need for the spiral stirrups to be welded around the outside of the multiple reinforcing bars. The two positioning structures 2 position and support the rear side of the multiple reinforcing bars. The setting of the two positioning structures 2 will not interfere with the work of internal positioning and installation of multiple stirrups 7 and external spiral stirrup welding during the binding of the reinforcing cage, ensuring that the welding of the reinforcing cage is completed in one position, and shortening the reinforcing cage binding cycle.

[0048] When it is necessary to remove the formed rebar cage, first, the rebar cage is fixed by the hoisting equipment. The hoisting equipment applies a force to the rebar cage to maintain its current height. The solenoid valve 216 in the right positioning structure 2 is controlled to open, and the high-pressure liquid inside the pressurization chamber enters the buffer chamber through the solenoid valve 216 and the second guide pipe 217. The right hydraulic expansion component 212 contracts, and the right end of the rebar cage loses its fixation. Then, the pulling component is controlled to work for a period of time and then paused, causing the left positioning structure 2 to move to the left a certain distance. The right end of the rebar cage is detached from the right positioning structure 2. Then, the solenoid valve 216 in the left positioning structure 2 is controlled to open, and the high-pressure liquid inside the pressurization chamber enters the buffer chamber through the solenoid valve 216 and the second guide pipe 217. The right hydraulic expansion component 212 contracts, and the fixation between the left end of the rebar cage and the left positioning structure 2 is removed. Then, the pulling component is controlled to work again, causing the left positioning structure 2 to move to the left and detach from the rebar cage. The binding auxiliary positioning device is directly connected and detached from the rebar cage, and the rebar cage disassembly is completed simply and conveniently.

[0049] When it is necessary to disassemble and move the binding auxiliary positioning device, control the pulling component to move the leftmost positioning structure 2 to the right side of the right positioning structure 2. Then, rotate the external thread rod 111 and external thread rod 110 to separate them from the outer guide block 9. This will remove the fixed connection between the left positioning structure 2 and the support structure 1, and allow the two positioning structures 2, the two guide rails 13, and the multiple guide rails 12 to be moved separately.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
