Abstract
Description
Technical Field
[0001] This invention relates to the field of precast beam processing and manufacturing technology, and more specifically, to a precast beam reinforcement processing and binding assembly line and processing and binding method. Background Technology
[0002] The most common layout for steel bar processing workshops is a horizontal arrangement, with the processing area parallel to the binding platform. Steel bars are typically processed within the processing area, and after completion and inspection by quality control personnel, smaller pieces can be moved to the binding area using forklifts with specialized tools. However, due to the length of the longitudinal reinforcement bars in box girders, a significant amount of manual labor is required to lift them to the binding platform. During the prefabrication of standard span simply supported box girders for railways, a large number of steel bars need to be bound, particularly the longitudinally distributed longitudinal reinforcement bars, which are long, numerous, and thin in diameter. For these long and thin bars, significant bending and deflection occur during lifting and transport. The semi-finished steel bars require extensive manual handling, necessitating 8-10 workers to coordinate, and only 8-10 bars can be transported at a time, resulting in extremely high labor intensity and severely impacting the efficiency of box girder reinforcement binding. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention provides a precast beam rebar processing and binding assembly line and method. It solves the problems of difficult rebar transportation and high labor intensity for workers, achieving the effects of convenient rebar transportation, reduced labor intensity for workers, and accelerated rebar binding construction efficiency for box girders.
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0005] A precast beam rebar processing and binding assembly line includes a rebar processing area and a rebar binding area arranged longitudinally; both sides of the rebar binding area are provided with rails extending into the rebar processing area; multiple overhead cranes are provided at the rails and move along the length of the rails, the overhead cranes are used to transport the processed rebars in the rebar processing area to the rebar binding area for binding.
[0006] With this invention, after the steel bars are processed in the steel bar processing area, they are hoisted by overhead cranes. If the steel bars are long, multiple overhead cranes can be used to hoist them to the steel bar binding area, thus eliminating the need for manual handling and significantly reducing the labor intensity of the workers. At the same time, it also speeds up the transportation efficiency of steel bars and accelerates the construction efficiency of box girder steel bar binding.
[0007] Preferably, the lower end of the overhead crane hoisting rope is provided with a hoisting assembly for hoisting the reinforcing bars. The hoisting assembly includes a binding member for binding the reinforcing bars and a connector for connecting the overhead crane hoisting rope; the connector is provided with a connecting mechanism for connecting the binding member.
[0008] With this invention, workers can quickly bundle steel bars using binding clips and connect the bundled steel bars to the connecting clips using a connecting mechanism. This allows workers to quickly place the bundled steel bars onto the connecting clips at the bottom of the overhead crane, facilitating crane lifting.
[0009] Preferably, the binding component includes a first clamping plate and a second clamping plate in a semi-circular shape, with one end of the first clamping plate and the second clamping plate hinged to each other; the first clamping plate and the second clamping plate together form a clamping area for clamping the reinforcing bars; a connecting plate is provided at the end of the first clamping plate and the second clamping plate away from the hinge, and a limiting hole is provided on the connecting plate; the connecting component includes a mounting seat connected to the overhead crane rope; the lower end of the mounting seat is provided with a mounting groove for the connecting plate to extend into; the side wall of the mounting seat is provided with a mounting hole communicating with the mounting groove, and a limiting pin extends through the mounting hole into the limiting hole.
[0010] With this invention, workers place multiple steel bars into the clamping area, then close the first and second clamping plates, setting several clamping points along the length of the steel bars, and clamping the steel bars with the first and second clamping plates. After the steel bars are clamped, the overhead crane's hoisting rope is lowered. Then, workers insert the connecting plates on the first and second clamping plates into the mounting slots of the mounting base, and then insert the limiting pins into the limiting holes on the connecting plates to connect the mounting base and the first and second clamping plates. Afterwards, the steel bars are transported to the steel bar binding area by several overhead cranes simultaneously, making it convenient for workers to quickly bundle the steel bars together and for the overhead cranes to quickly lift the steel bars.
[0011] Preferably, the inner wall of the mounting hole is recessed inward along the circumferential direction to form a mounting cavity, and the side wall of the limiting pin located in the mounting cavity expands outward along the circumferential direction to form a first flange. The mounting cavity is also provided with a spring that pushes the first flange to extend the limiting pin into the mounting groove; the end of the limiting pin away from the first flange is provided with a second flange that fits against the side wall of the mounting seat.
[0012] With this invention, the worker first pulls the limiting pin, then inserts the connecting plate into the mounting groove, and releases the limiting pin. Under the push of the spring, the limiting pin is inserted into the limiting hole on the connecting plate, thus facilitating the worker to quickly connect the binding parts and the connecting parts. After the crane transports the steel bars to the steel bar binding area, the worker pulls the limiting pin to pull it out of the limiting hole, releasing the fixation on the first and second clamping plates. Then, the first and second clamping plates are separated, making it convenient for the worker to remove the steel bars from the clamping area.
[0013] Preferably, the mounting cavity is provided with a guide rod arranged along the depth direction of the mounting cavity, a spring is sleeved on the guide rod, and a through hole is provided at the first flange for the guide rod to pass through.
[0014] With this invention, when the operator pulls the limiting pin, the first flange slides along the guide rod, thereby improving the stability of the limiting pin during movement.
[0015] Preferably, the end of the second flange furthest from the mounting base is provided with a handle.
[0016] With this invention, workers can move the limit pin by pulling the handle, making it easier for them to pull the handle.
[0017] Preferably, the end of the limiting pin that extends into the mounting groove has an inclined surface that mates with the connecting plate.
[0018] With this invention, when the worker inserts the connecting plate into the mounting slot, the connecting plate presses against the inclined surface of the limiting pin, thereby pushing the limiting pin into the mounting cavity, so that the worker does not need to pull the limiting pin when inserting the connecting plate into the mounting slot.
[0019] Preferably, the upper end of the mounting base is provided with a sliding wheel through which the overhead crane hoisting rope passes.
[0020] With this invention, installers can pass the hoisting rope at the bottom of the overhead crane through the pulley, thus facilitating the connection between the mounting base and the hoisting rope.
[0021] This invention relates to a method for processing and binding reinforcing bars in precast beams, the specific steps of which are as follows:
[0022] First, the steel bars are processed in the steel bar processing area. Then, the processed steel bars are placed in the clamping area, and the first and second clamping plates are closed. Through the above steps, several clamping points are set along the length of the steel bars, and the steel bars are clamped by the first and second clamping plates. After the steel bars are clamped, the overhead crane's hoisting rope is lowered. Then, the workers insert the connecting plates on the first and second clamping plates into the mounting slots of the mounting base, and then insert the limiting pins into the limiting holes on the connecting plates to connect the mounting base and the first and second clamping plates. Then, the steel bars are transported to the steel bar binding area by several overhead cranes at the same time. Finally, the workers bind the steel bars on the binding jigs in the steel bar binding area to form a precast beam.
[0023] This invention provides a better way for workers to quickly hang the processed steel bars under the overhead crane for easy hoisting; at the same time, by using the overhead crane to replace manual handling of the steel bars, it significantly reduces the labor intensity of workers and speeds up the handling efficiency of the steel bars.

[0032] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.
[0033] Example 1
[0034] like Figures 1-8 As shown, this embodiment provides a precast beam rebar processing and binding assembly line, which includes a rebar processing area 120 and a rebar binding area 110 arranged longitudinally; both sides of the rebar binding area 110 are provided with rails 100 extending into the rebar processing area 120; multiple overhead cranes 210 are provided at the rails 100, which move along the length of the rails 100, and the overhead cranes 210 are used to transport the processed rebars in the rebar processing area 120 to the rebar binding area 110 for binding.
[0035] In this embodiment, after the steel bars are processed in the steel bar processing area 120, they are hoisted by overhead crane 210. If the steel bars are long, multiple overhead cranes can be used to hoist them to the steel bar binding area 110, thus eliminating the need for manual handling and significantly reducing the labor intensity of the workers. At the same time, it also speeds up the transportation efficiency of the steel bars and accelerates the construction efficiency of the box girder steel bar binding.
[0036] In this embodiment, the lower end of the hoisting rope of the overhead crane 210 is provided with a hoisting assembly 220 for hoisting steel bars. The hoisting assembly 220 includes a binding member 320 for binding steel bars and a connector 310 for connecting the hoisting rope of the overhead crane 210. The connector 310 is provided with a connecting mechanism for connecting the binding member 320.
[0037] In this embodiment, workers can quickly tie the reinforcing bars using the binding 320 and connect the tied reinforcing bars to the connector 310 using the connecting mechanism. This allows workers to quickly place the tied reinforcing bars onto the connector 310 at the bottom of the crane, facilitating crane lifting.
[0038] In this embodiment, the binding member 320 includes a first clamping plate 410 and a second clamping plate 420 in a semi-circular shape, with one end of the first clamping plate 410 and the second clamping plate 420 hinged to each other; the first clamping plate 410 and the second clamping plate 420 together constitute a clamping area for clamping the reinforcing bar; a connecting plate 430 is provided at the end of the first clamping plate 410 and the second clamping plate 420 away from the hinge, and a limiting hole 440 is provided on the connecting plate 430; the connecting member 310 includes a mounting seat 530 connected to the hoisting rope of the overhead crane 210; the lower end of the mounting seat 530 is provided with a mounting groove 610 for the connecting plate 430 to extend into; the side wall of the mounting seat 530 is provided with a mounting hole 710 communicating with the mounting groove 610, and a limiting pin 810 extends through the mounting hole 710 and into the limiting hole 440.
[0039] In this embodiment, workers place multiple reinforcing bars into the clamping area, then close the first clamping plate 410 and the second clamping plate 420, setting several clamping points along the length of the reinforcing bars, and clamping the reinforcing bars with the first clamping plate 410 and the second clamping plate 420. After the reinforcing bars are clamped, the hoisting rope of the overhead crane 210 is lowered. Then, workers insert the connecting plate 430 on the first clamping plate 410 and the second clamping plate 420 into the mounting groove 610 of the mounting base 530, and then insert the limiting pin 810 into the limiting hole 440 on the connecting plate 430 to connect the mounting base 530 and the first clamping plate 410 and the second clamping plate 420. Then, the reinforcing bars are transported to the reinforcing bar binding area 110 by several overhead cranes simultaneously, which makes it convenient for workers to quickly bind the reinforcing bars together and for the overhead cranes to quickly lift the reinforcing bars.
[0040] In this embodiment, the inner sidewall of the mounting hole 710 is recessed inward along the circumferential direction to form a mounting cavity 670. The sidewall of the limiting pin 810 located in the mounting cavity 670 expands outward along the circumferential direction to form a first flange 620. A spring 650 is also provided in the mounting cavity 670 to push the first flange 620 so that the limiting pin 810 extends into the mounting groove 610. The end of the limiting pin 810 away from the first flange 620 is provided with a second flange 640 that fits against the sidewall of the mounting base 530.
[0041] In this embodiment, the worker first pulls the limiting pin 810, then inserts the connecting plate 430 into the mounting groove 610, and releases the limiting pin 810. Under the push of the spring 650, the limiting pin 810 is inserted into the limiting hole 440 on the connecting plate 430, thus facilitating the worker to quickly connect the binding piece 320 and the connecting piece 310. After the crane transports the steel bars to the steel bar binding area 110, the worker pulls the limiting pin 810 to pull it out of the limiting hole 440, releasing the fixation on the first clamping plate 410 and the second clamping plate 420. Then, the first clamping plate 410 and the second clamping plate 420 are separated, making it convenient for the worker to take the steel bars out of the clamping area.
[0042] In this embodiment, a guide rod 630 is provided in the mounting cavity 670 along the depth direction of the mounting cavity 670, a spring 650 is sleeved on the guide rod 630, and a through hole 820 is provided at the first flange 620 for the guide rod 630 to pass through.
[0043] In this embodiment, when the operator pulls the limiting pin 810, the first flange 620 slides along the guide rod 630, thereby improving the stability of the limiting pin 810 when it moves.
[0044] In this embodiment, a handle 520 is provided at the end of the second flange 640 away from the mounting base 530.
[0045] In this embodiment, the operator can move the limit pin 810 by pulling the handle 520, which makes it convenient for the operator to pull the handle 520.
[0046] In this embodiment, the end of the limiting pin 810 that extends into the mounting groove 610 is provided with an inclined surface 660 that cooperates with the connecting plate 430.
[0047] In this embodiment, when the operator inserts the connecting plate 430 into the mounting groove 610, the connecting plate 430 presses the inclined surface 660 on the limiting pin 810, thereby pushing the limiting pin 810 into the mounting cavity 670, so that the operator does not need to pull the limiting pin 810 when inserting the connecting plate 430 into the mounting groove 610.
[0048] In this embodiment, the upper end of the mounting base 530 is provided with a sliding wheel 510 through which the hoisting rope of the overhead crane 210 passes.
[0049] In this embodiment, the installer passes the hoisting rope at the lower end of the overhead crane 210 through the sliding wheel 510, thereby facilitating the connection between the mounting base 530 and the hoisting rope.
[0050] This embodiment relates to a method for processing and binding reinforcing bars in precast beams. The specific steps are as follows.
[0051] First, the steel bars are processed in the steel bar processing area 120. Then, the processed steel bars are placed in the clamping area, and the first clamping plate 410 and the second clamping plate 420 are closed. Through the above steps, several clamping points are set along the length of the steel bars, and the steel bars are clamped by the first clamping plate 410 and the second clamping plate 420. After the steel bars are clamped, the hoisting rope of the overhead crane 210 is lowered. Then, the workers insert the connecting plate 430 on the first clamping plate 410 and the second clamping plate 420 into the mounting groove 610 of the mounting base 530. Then, the limiting pin 810 is inserted into the limiting hole 440 on the connecting plate 430 to connect the mounting base 530 and the first clamping plate 410 and the second clamping plate 420. Then, the steel bars are transported to the steel bar binding area 110 by several overhead cranes lifting at the same time. Finally, the workers bind the steel bars on the binding jig in the steel bar binding area 110 to form a precast beam.
[0052] This embodiment makes it easier for workers to quickly hang the processed steel bars under the overhead crane for easy hoisting; at the same time, by using the overhead crane to replace manual handling of the steel bars, the labor intensity of the workers is reduced and the efficiency of steel bar handling is increased.
[0053] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
