Description

[0002] With the rapid development of infrastructure construction in my country, the requirements for standardized highway construction are constantly increasing, and the requirements for concrete quality are also increasing accordingly. In highway subgrade drainage projects, circular culverts are the most common type of culvert structure, and their culvert sections are usually prefabricated with reinforced concrete. In the prefabrication process of circular culverts, the control of the thickness of the steel bar protective layer is crucial. To ensure the uniformity of the thickness of the protective layer, it is necessary to ensure the consistency of the spacing between the inner and outer rings of steel bars and the spacing between the upper and lower layers of steel bars during the tying of the steel cage, and ensure that the overall steel cage remains in a vertical state, so that the thickness and strength of the protective layer of the prefabricated pipe section are uniform.

[0003] However, at existing construction sites, the production of circular culvert reinforcement is usually done by three to four workers manually coiling the reinforcement around the steel pipe bracket to form multiple rings. Due to the limitations of this method, the spacing between the inner and outer layers of the reinforcement cage and the spacing between the upper and lower layers of the reinforcement cage are often difficult to accurately control, resulting in the reinforcement cage being difficult to meet standardized requirements in terms of verticality and protective layer thickness, thereby affecting the quality and strength consistency of the final prefabricated pipe section. The shortcomings of this existing technology expose the lack of effective structural control methods in the production process of the circular culvert reinforcement cage, and there is an urgent need to improve the technology to achieve precise spacing control and consistency of protective layer thickness.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. 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 implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0023] The following is combined with Figures 1 to 8 , a circular tube culvert steel bar manufacturing frame provided in the present application is described in detail through specific embodiments and application scenarios.

[0024] Combination Figure 1 , Figure 2A round pipe culvert steel bar manufacturing frame includes a frame 100, a cross bar 200 and a coiled steel bar winding mechanism 300, the cross bar 200 is horizontally mounted on the frame 100, and the coiled steel bar winding mechanism 300 is on the cross bar 200. Exemplarily, the coiled steel bar winding mechanism 300 includes a winding rod 310 and a rotating assembly 320, the rotating assembly 320 is rotatably arranged on the cross bar 200, and the rotating assembly 320 is symmetrically arranged in two groups on the cross bar 200, the winding rod 310 is detachably arranged between the two groups of rotating assemblies 320, and the winding rod 310 is arranged between the two groups of rotating assemblies 320 around the rotation axis of the cross bar 200 to form a circumferential winding surface for the coiled steel bar to be wound, and the surface of the winding rod 310 is provided with a plurality of clamping positions 420 at intervals, and the clamping positions 420 on the plurality of winding rods 310 correspond to each other circumferentially to form a circumferential winding route for the coiled steel bar to be embedded.

[0025] Exemplarily, the frame 100 is in an L-shape, and the crossbar 200 is horizontally arranged on the frame 100 to form a U-shape. Further, in order to improve the stability of the frame 100, a diagonal brace is arranged between the vertical rod and the horizontal rod of the frame 100 to improve the overall stability of the frame 100.

[0026] On this basis, through the coordinated action of the frame 100, the cross bar 200 and the coiled steel bar winding mechanism 300, the precise control of the steel bar cage of the round pipe culvert can be achieved during the manufacturing process, thereby effectively solving the problem of uneven spacing between the inner and outer layers of steel bars and the spacing between the upper and lower layers of steel bars when the steel bars are coiled by hand in the traditional way, and the consistency of the thickness of the protective layer can be ensured. Specifically, the coiled steel bar winding mechanism 300 of the tire frame is composed of a winding rod 310 and a rotating assembly 320. The arrangement of the rotating assembly 320 enables the winding rod 310 to rotate freely along its rotation axis on the cross bar 200, and the interval arrangement and symmetrical configuration of the rotating assembly 320 help to form a stable winding structure. A plurality of snap-in positions 420 are provided on the surface of each winding rod 310, and the distribution of these snap-in positions 420 conforms to the circumferentially uniform design, so that the round steel bar can be accurately embedded in the snap-in positions 420 on the winding rod 310 during the winding process, thereby forming a stable and uniform circumferential winding surface.

[0027] Through this adjustable winding rod 310 structure, the spacing and arrangement position of each circle of steel bars can be ensured to be consistent at all times, avoiding errors in manual operation. Specifically, the winding route of the round steel bars is determined by the multiple clamping positions 420 on the winding rod 310, and the uniform distribution of the clamping positions 420 ensures the precise control of the steel bar spacing. The design of this structure effectively avoids the misalignment problem of the steel bars inside the steel cage and the upper and lower layers, thereby ensuring the consistency of the protective layer thickness of each part of the circular culvert steel cage, further improving the structural strength and stability of the prefabricated pipe section.

[0028] In addition, the adjustability of the tire frame makes it adaptable to the production requirements of steel bars of different specifications. The configuration of the crossbar 200 and the winding rod 310 can be adjusted according to the actual construction situation to meet the requirements of different pipe segment sizes and steel bar specifications. Compared with the traditional method of manually tying steel cages, the present invention can greatly improve the efficiency and accuracy of steel cage production, reduce the uncertainty of manual operation, ensure the uniformity and stability of the steel cage, and provide a solid foundation for subsequent concrete pouring.

[0029] In summary, the circular culvert steel bar manufacturing frame of the present invention, through the innovation of structural design, provides an effective, precise and efficient method for manufacturing steel cages, which not only optimizes the quality control of the steel cages, but also improves production efficiency, solves the problems of uneven spacing and inconsistent protective layer thickness existing in traditional manual methods, and has significant technical effects.

[0030] In some embodiments, Figure 1 , Figure 2 As shown, the rotating assembly 320 includes a rotating sleeve 321 and a limiting rod 322. The rotating sleeve 321 is rotatably sleeved on the cross bar 200. Limiting plates 210 are provided on the cross bar 200 and at both ends of the rotating sleeve 321. The limiting plates 210 are fitted with the ends of the rotating sleeve 321 to limit the displacement of the rotating sleeve 321 in the length direction of the cross bar 200.

[0031] Exemplarily, a plurality of limit rods 322 are evenly spaced around the outer wall of the rotating sleeve 321 , and the length direction of the limit rods 322 is perpendicular to the length direction of the cross bar 200 , and the winding rod 310 is detachably arranged on the corresponding limit rods 322 on the two sets of rotating components 320 .

[0032] By providing a combined structure of a rotating sleeve 321 and a limiting rod 322 in the rotating assembly 320, the accuracy of winding the steel bars and the stability of the device are further improved. Specifically, the rotating sleeve 321 is rotatably sleeved on the cross bar 200, and limiting plates 210 are respectively provided at both ends of the cross bar 200. The fitting of the limiting plates 210 and the ends of the rotating sleeve 321 can effectively limit the displacement of the rotating sleeve 321 along the length direction of the cross bar 200, ensuring that the rotating assembly 320 always remains in the predetermined working position. This design effectively avoids the problem of steel bar winding position deviation caused by the axial displacement of the rotating sleeve 321 during the winding process, thereby improving the manufacturing accuracy of the steel cage.

[0033] In addition, the limiting rods 322 are evenly spaced and arranged on the circumference of the outer wall of the rotating sleeve 321, and their length direction is perpendicular to the length direction of the cross bar 200. This structural design enables the winding rod 310 to be firmly installed between the limiting rods 322 corresponding to the two sets of rotating components 320. The uniform distribution of the limiting rods 322 can ensure the arrangement accuracy and stability of the winding rods 310, so that the winding path of the steel bars is more uniform and consistent, and the spacing control effect of the inner and outer layers of the steel cage and the upper and lower layers of the steel bars is further optimized.

[0034] In some embodiments, in combination Figure 2 , Figure 3 The limiting rod 322 has a plurality of first insertion holes 510 on the rod wall near its end and along the length direction of the limiting rod 322. The first insertion holes 510 on the two corresponding limiting rods 322 correspond to each other one by one, and the first insertion holes 510 are used for inserting the ends of the winding rods 310.

[0035] Exemplary, combined Figure 4 A plurality of groups of clamping members 400 are provided on the winding rod 310 along its length direction. The clamping member 400 is composed of two clamping strips 410 , and the clamping position 420 is formed between the two clamping strips 410 .

[0036] When manufacturing circular culvert reinforcement, the coiled round reinforcement can be released in sequence according to a plurality of engaging positions 420 in the same circumferential direction. By setting a plurality of engaging positions 420, the coiled round reinforcement can be guided to be wound in a predetermined direction, thereby improving the manufacturing efficiency of the reinforcement cage.

[0037] In some embodiments, Figure 3 As shown, the interior of the limit rod 322 is hollow, and an insertion portion 500 is rotatably provided inside the limit rod 322. A first plug hole 510 is opened on the insertion portion 500 along the axial direction of the insertion portion 500, and the cross-sectional shape of the first plug hole 510 is triangular or rectangular. An insertion rod 311 is coaxially provided at the end of the winding rod 310, and the cross-sectional shape of the insertion rod 311 is adapted to the cross-sectional shape of the first plug hole 510, so that the winding rod 310 and the insertion portion 500 can achieve synchronous rotation when plugged in. Exemplarily, a first torsion spring 520 is sleeved on the rod section of the insertion part 500 located inside the limiting rod 322, one end of the first torsion spring 520 is connected to the outer wall of the insertion part 500, and the other end is connected to the inner wall of the limiting rod 322. The first torsion spring 520 always has a tendency to allow the insertion part 500 and the winding rod 310 to rotate synchronously to a preset position, and the preset position is configured so that the clamping position 420 on the winding rod 310 is in a state facing away from the cross bar 200. It is worth noting that the drawings of this application only show the case where the cross-sectional shape of the first plug hole 510 is rectangular.

[0038] On this basis, after the insertion rod 311 at the end of the winding rod 310 is inserted into the first insertion hole 510, since the shape of the first insertion hole 510 is triangular or rectangular, the winding rod 310 can realize synchronous rotation with the pre-insertion part 500. Under the torsion of the first torsion spring 520, the clamping position 420 on the winding rod 310 is in a state facing away from the cross bar 200, so that it is convenient to wind the round steel bar on the multiple clamping positions 420 in the circumferential direction, thereby improving the winding efficiency.

[0039] In some embodiments, in combination Figure 1 , Figure 2 as well as Figure 5 , and also includes an adjustment mechanism 600, which is installed on one of the rotating assemblies 320. The adjustment mechanism 600 can drive the multiple winding rods 310 to rotate simultaneously, so that the clamping position 420 on the winding rod 310 is in a state facing the side of the cross bar 200. After the round steel bar is wound and welded to form a steel cage, it is necessary to remove the steel cage from the multiple winding rods 310. At this time, due to the blocking restriction of the clamping member 400, the steel cage is not easy to be removed from the multiple winding rods 310. On this basis, through the adjustment mechanism 600, the multiple winding rods 310 are rotated simultaneously, so that the clamping position 420 on the winding rod 310 is in a state facing the side of the cross bar 200. At this time, the positions of the multiple clamping members 400 will not interfere with the removal of the steel cage, that is, the manufactured steel cage can be removed from the multiple winding rods 310 along the length direction of the cross bar 200.

[0040] Exemplarily, the adjustment mechanism 600 includes a bracket 610, an active adjustment component 620 and a passive adjustment component 630, the bracket 610 is installed on the side of one group of rotating components 320 away from the other group of rotating components 320, multiple groups of passive adjustment components 630 are provided on the bracket 610, and one group of passive adjustment components 630 corresponds to one winding rod 310, one group of active adjustment components 620 is provided on the bracket 610, and one group of active adjustment components 620 is simultaneously connected to multiple groups of passive adjustment components 630, and the active adjustment component 620 has a switchable first state and a second state, wherein, when the active adjustment component 620 is in the first state, multiple passive adjustment components 630 simultaneously drive multiple winding rods 310 to rotate until multiple clamping positions 420 are all in a state facing the side of the cross bar 200; when the active adjustment component 620 is in the second state, multiple first torsion springs 520 simultaneously drive multiple winding rods 310 to rotate until multiple clamping positions 420 are all in a state facing away from the side of the cross bar 200. In this way, through the cooperation of the active adjustment component 620 and the passive adjustment component 630, multiple winding rods 310 can be rotated simultaneously to improve the convenience of operation.

Further, the interior of the extension body 612 is hollow, the interior of the hollow disc 611 is connected to the interior of the extension body 612, the passive adjustment component 630 is arranged in the extension body 612 and the hollow disc 611, and the active adjustment component 620 is arranged on the hollow disc 611.

[0042] Exemplarily, the active adjustment assembly 620 includes an active rotating roller 621, an extension rod 622, and a turntable 623. The active rotating roller 621 is coaxially and rotatably disposed in the hollow disc 611.

The guide rod 635 is arranged in parallel in the extension body 612, and a guide channel for the main rope body 634a to pass through is axially penetrated in the guide rod 635, and one end of the main rope body 634a away from the branch rope body 634b is connected to the outer peripheral wall of the active rotating roller 621.

[0045] Exemplarily, the second torsion spring 632 is sleeved on the passive rotating roller 631, one end of the second torsion spring 632 is connected to the inner wall of the extension body 612, and the other end is connected to the outer peripheral wall of the passive rotating roller 631, and when the second torsion spring 632 is in a natural state, the second socket 631a is always opposite to the first socket 510; wherein, when the active adjustment component 620 is in the second state, the split rope body 634b is wound half a circle on the upper surface of the winding wheel 633, and when the active adjustment component 620 is in the first state, the rope segment part of the split rope body 634b is completely separated from the winding wheel 633, and at this time the length direction of the split rope body 634b is parallel to the length direction of the extension body 612; when the active adjustment component 620 is in the first state, the state in the switching process between the first state and the second state, and the second state, the connecting rope 634 is always in a taut state.

[0046] Further, combined with Figure 4 A slot 312 is axially provided at the end of the winding rod 310, and the insertion rod 311 is slidably inserted into the slot 312. A spring 313 is provided between the insertion rod 311 and the inner end wall of the slot 312, and the spring 313 always has a tendency to push the insertion rod 311 out of the slot 312. Exemplarily, a movable groove is provided at the end of the winding rod 310 and along the length direction of the winding rod 310, and the movable groove is connected to the slot 312, and a shift block is vertically provided on the insertion rod 311, and a plurality of anti-slip stripes are provided on the surface of the shift block facing away from the insertion rod 311, so that the operator can easily push the shift block with fingers to control the position of the insertion rod 311 in the slot 312.

[0047] On this basis, when the winding rod 310 needs to be installed between the limiting rods 322, the shifting block is first pushed by hand so that the insertion rod 311 overcomes the elastic force of the spring 313 and at least partially shrinks in the slot 312. At this time, the length of the entire winding rod 310 will be relatively shortened, and it can be directly placed between the two limiting rods 322. Then, the insertion rod 311 at the other end of the winding rod 310 is aligned with the first insertion hole 510 and inserted into it, and then the insertion rod 311 at this end that shrinks in the slot 312 is aligned with the first insertion hole 510 on the corresponding insertion part 500, and then the shifting block is released. Under the elastic force of the spring 313, the insertion rod 311 at this end will be inserted into the second insertion hole 631a in the passive rotating roller 631 after passing through the first insertion hole 510. All winding rods 310 are installed according to the above, so that all winding rods 310 can be installed.

[0048] When the winding rod 310 is installed in place, in the absence of external force, the first torsion spring 520 and the second torsion spring 632 will drive the winding rod 310 to rotate and position it so that the multiple clamping positions 420 on the winding rod 310 are all in a state facing away from the side of the cross bar 200. In this state, the outer circumferential surfaces of the multiple winding rods 310 will form a circumferential winding route for the coiled steel bars to be inserted. Therefore, the operator can bend the coiled steel bars in turn according to the circumferential winding route formed by these clamping positions 420, so that the coiled steel bars can be used on the surfaces of multiple parallel winding rods 310 to shape the outer frame of the steel cage.

[0049] When the steel cage is completed, the engaging position 420 will jam the steel cage, making it impossible to remove the steel cage from the plurality of winding rods 310 normally. Therefore, in this case, the operator can manually rotate the turntable 623 to rotate the active rotating roller 621. At this time, the active rotating roller 621 will drive the end of the main rope 634a close to itself to move synchronously. Under the guidance of the guide rod 635, the end of the main rope 634a away from the active rotating roller 621 will be subjected to the vertical downward pulling force brought by the rotation of the active rotating roller 621. At the same time, this part of the pulling force will be directly applied to the rope body 634b; at this time, since the rope body 634b is partially attached to the upper surface of the winding wheel 633 by half a circle, after being subjected to the pulling force, the rope body 634b will move vertically downward, thereby driving the winding wheel 633 to rotate 180°, until the rope body 634b is completely removed from the winding wheel 633. In this process, the passive rotating roller 631 will also synchronously drive the winding rod 310 to rotate 180°, that is, the clamping position 420 is rotated from the side away from the cross bar 200 to the side facing the cross bar 200. After rotating 180°, the clamping member 400 and the clamping position 420 have completely avoided the external steel cage, so the steel cage will not be restricted by the clamping member 400 at this time and can be normally removed from the multiple winding rods 310.

[0050] After one steel cage is made, the operator releases the turntable 623. Under the reset torque of the first torsion spring 520 and the second torsion spring 632, the engaging position 420 can automatically rotate to the side facing away from the cross bar 200 to facilitate the making of the next steel cage.

[0051] It is worth noting that, generally, when making a steel cage, the winding rod 310 only needs to be installed at the two first insertion holes 510 farthest from the cross bar 200, and the first insertion holes 510 at other positions are used when making other materials. Because the positions of the two first insertion holes 510 farthest from the cross bar 200 can directly remove the manufactured steel cage along the axis direction of the cross bar 200, while the positions of the other positions cannot be removed.
