Description

Technical Field

[0001] This utility model relates to the technical field of precast component production equipment, specifically to an automatic steel bar feeding device for precast components. Background Technology

[0002] In the production of precast components, the placement of reinforcing bars is a crucial step in ensuring the structural strength of the components. Currently, most companies in the industry still use manual placement, where workers manually move the reinforcing bars into the mold and place them according to the design position.

[0003] Based on the above, the inventors have discovered the following problems: Currently, steel reinforcement placement is mostly done manually, which is labor-intensive and inefficient. Especially in the production of large precast components, where the amount of steel reinforcement used in a single batch is large, manual placement requires a lot of time and manpower.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an automatic steel bar placement device for prefabricated components, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic steel bar placement device for precast components, so as to solve the problem mentioned in the background art that the current steel bar placement is mostly done manually, which is labor-intensive and inefficient. Especially in the production of large precast components, the amount of steel bars used in a single batch is large, and manual placement requires a lot of time and manpower.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: An automatic rebar placement device for precast components includes a gantry frame. A pair of crossbeams are mounted at the bottom of the gantry frame. Wheel seats are mounted on both sides of the bottom of each crossbeam. A wheel axle is rotatably connected to the inner side of each wheel seat. A traveling wheel is mounted at one end of each wheel axle, and a track is provided at the bottom of each traveling wheel. A first motor is mounted on one end face of each pair of wheel seats, and the output end of the first motor is connected to one end of the wheel axle. A sliding opening is provided at the top of the gantry frame. A sleeve column is provided at the top of the gantry frame. An extension column is slidably connected to the bottom of the inner side of the sleeve column. A translation mechanism for moving the sleeve column is provided at the top of the gantry frame. An electric turntable is mounted at the bottom of the extension column. A connecting plate is mounted on the rotating end of the electric turntable. A rebar clamping mechanism is provided at the bottom of the connecting plate. A height adjustment mechanism for adjusting the height of the extension column is provided inside the sleeve column.

[0007] Furthermore, the translation mechanism includes a first one-way threaded rod, both ends of which are rotatably connected to retaining seats. The bottom end of the retaining seats is fixedly connected to the top end of the gantry frame. A movable block is fitted on the outer side of the first one-way threaded rod. The bottom end of the movable block is fixedly connected to the top end of the sleeve column. A second motor is installed on one side of the top end of the sleeve column. The output end of the second motor is connected to one end of the first one-way threaded rod.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the first one-way threaded rod of the translation mechanism cooperates with the retaining seat to ensure the stable rotation of the threaded rod; the second motor drives the first one-way threaded rod to drive the movable block and the sleeve column to move laterally, thereby achieving precise positioning of the steel bars in the lateral direction of the precast platform and avoiding positional deviations caused by manual placement.

[0009] Furthermore, the two sides of the movable block are slidably connected with limit rods, and one side of each pair of limit rods is fixedly connected to the inner sides of the sliding opening.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the limiting rods slidably connected on both sides of the movable block guide the movable block to move only in a straight line, avoiding the displacement of the sleeve caused by the rotation of the movable block with the first one-way threaded rod.

[0011] Furthermore, the rebar clamping mechanism includes a bidirectional threaded rod, with a first retainer rotatably connected to each end of the bidirectional threaded rod. The top end of the first retainer is fixedly connected to the bottom end of the connecting plate. Movable frames are fitted onto both ends of the bidirectional threaded rod, and three rebar clamping claws are installed at the bottom ends of each pair of movable frames. A third motor is installed on one side of one of the first retainers, and the output end of the third motor is connected to one end of the bidirectional threaded rod.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the bidirectional threaded rod of the rebar clamping mechanism cooperates with the first retainer to ensure the stable rotation of the threaded rod; the bidirectional threaded rod is driven by the third motor, which drives the two movable frames on both sides to move relative to each other, so that the rebar clamping gripper can clamp or release the rebar synchronously, adapting to the gripping needs of rebars of different diameters.

[0013] Furthermore, a pair of sliding rods are slidably connected to the inner side of the pair of movable frames, and the two ends of the sliding rods are respectively fixedly connected to the inner side of the first retainer.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, through the sliding rod connected to the inner side of the movable frame, the movable frame is guided to move only along the axial direction of the bidirectional threaded rod, thus avoiding the tilting of the rebar clamp caused by the rotation of the movable frame with the threaded rod.

[0015] Furthermore, the height adjustment mechanism includes a second one-way threaded rod, and the top end of the extension column is provided with a threaded hole. The outer side of the second one-way threaded rod and the inner side of the threaded hole are engaged. The top end of the second one-way threaded rod is rotatably connected to a second retainer, and the two ends of the second retainer are respectively fixedly connected to the inner sides of the sleeve column.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by engaging the second one-way threaded rod of the height adjustment mechanism with the threaded hole of the extension column, the rotation of the threaded rod is converted into the vertical lifting and lowering of the extension column, thereby achieving precise adjustment of the height of the rebar clamping mechanism.

[0017] Furthermore, a fourth motor is installed at the top of one side of the sleeve column, and bevel gears are fitted at the output end of the fourth motor and the top of the second one-way threaded rod. The fourth motor and the second one-way threaded rod are connected by bevel gear transmission.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that by meshing the fourth motor with the bevel gear at the top of the second one-way threaded rod, the direction of power can be reversed, and the horizontal output force of the motor can be converted into the vertical rotational force of the threaded rod.

[0019] Compared with existing technologies, the beneficial effects of this utility model are as follows: This automatic rebar placement device for precast components forms a stable frame through a gantry and a cross frame, providing rigid support for rebar placement and preventing deformation during operation; the wheel seats, wheel axles, and traveling wheels work together to move the entire device on the track, achieving a wide range of rebar placement across the precast platform; the first motor drives the traveling wheels, replacing manual pushing and reducing labor intensity; the sliding joint provides a moving channel for the sleeve column, and the translation mechanism enables precise lateral movement of the sleeve column; the sliding cooperation between the sleeve column and the extension column, combined with the height adjustment mechanism, adjusts the height of the rebar clamping mechanism to adapt to the rebar placement requirements of precast components of different thicknesses; the electric turntable drives the connecting plate to rotate, enabling multi-angle placement of rebar; the rebar clamping mechanism stably grips the rebar, preventing rebar from falling off during placement.

[0023] Please see Figures 1-5This utility model provides a technical solution: an automatic rebar placement device for precast components, including a gantry frame 1, a pair of crossbeams 2 installed at the bottom of the gantry frame 1, wheel seats 3 installed on both sides of the bottom of the crossbeams 2, wheel axles 4 rotatably connected to the inner side of the wheel seats 3, a traveling wheel 5 installed at one end of the wheel axle 4, and a track 7 provided at the bottom of the traveling wheel 5. A first motor 6 is installed on one end of the pair of wheel seats 3, and the output end of the first motor 6 is connected to one end of the wheel axle 4. A sliding opening 101 is opened at the top of the gantry frame 1, a sleeve column 8 is provided at the top of the inner side of the gantry frame 1, an extension column 10 is slidably connected to the bottom of the inner side of the sleeve column 8, a translation mechanism 9 for moving the sleeve column 8 is provided at the top of the gantry frame 1, an electric turntable 11 is installed at the bottom of the extension column 10, a connecting plate 12 is installed at the rotating end of the electric turntable 11, and a rebar clamping mechanism 13 is provided at the bottom of the connecting plate 12. The internal structure of column 8 is equipped with a height adjustment mechanism 14 for adjusting the height of extension column 10. This mechanism, along with the gantry frame 1 and cross frame 2, forms a stable frame, providing rigid support for the rebar placement and preventing deformation during operation. Wheel seats 3, wheel axles 4, and traveling wheels 5 work together to move the entire device along the track 7, enabling large-scale rebar placement across the precast platform. The first motor 6 drives the traveling wheels 5, replacing manual pushing and reducing labor intensity. A sliding opening 101 provides a movement channel for the sleeve column 8, enabling precise lateral movement of the sleeve column 8 in conjunction with the translation mechanism 9. The sliding engagement between the sleeve column 8 and extension column 10, combined with the height adjustment mechanism 14, adjusts the height of the rebar clamping mechanism 13 to accommodate rebar placement requirements for precast components of varying thicknesses. An electric turntable 11 rotates the connecting plate 12, allowing for multi-angle rebar placement. The rebar clamping mechanism 13 stably grips the rebar, preventing it from falling off during placement.

[0024] The translation mechanism 9 includes a first one-way threaded rod 901, with retaining seats 902 rotatably connected to both ends of the first one-way threaded rod 901. The bottom end of the retaining seat 902 is fixedly connected to the top end of the gantry frame 1. A movable block 903 is fitted on the outer side of the first one-way threaded rod 901, with the bottom end of the movable block 903 fixedly connected to the top end of the sleeve column 8. A second motor 905 is installed on one side of the top end of the sleeve column 8, with the output end of the second motor 905 connected to one end of the first one-way threaded rod 901. The first one-way threaded rod 901 of the translation mechanism 9 cooperates with the retaining seat 902 to ensure stable rotation of the threaded rod. The second motor 905 drives the first one-way threaded rod 901, causing the movable block 903 and the sleeve column 8 to move laterally, achieving precise positioning of the reinforcing bars in the lateral direction of the precast platform and avoiding positional deviations caused by manual placement.

[0025] Among them, the two sides of the movable block 903 are slidably connected to the limiting rods 904. One side of each pair of limiting rods 904 is fixedly connected to the inner sides of the slide 101. Through the limiting rods 904 slidably connected to the two sides of the movable block 903, the movable block 903 is guided to move only in a straight line, so as to avoid the movable block 903 rotating with the first one-way threaded rod 901 and causing the sleeve 8 to shift.

[0026] The rebar clamping mechanism 13 includes a bidirectional threaded rod 1301, with a first retainer 1302 rotatably connected to both ends of the bidirectional threaded rod 1301. The top end of the first retainer 1302 is fixedly connected to the bottom end of the connecting plate 12. Both ends of the bidirectional threaded rod 1301 are fitted with movable frames 1303. Three rebar clamping claws 1306 are installed at the bottom of each pair of movable frames 1303. A third motor 1305 is installed on one side of one of the first retainers 1302. The output end of the third motor 1305 is connected to one end of the bidirectional threaded rod 1301. The bidirectional threaded rod 1301 of the rebar clamping mechanism 13 cooperates with the first retainer 1302 to ensure stable rotation of the threaded rod. The third motor 1305 drives the bidirectional threaded rod 1301, causing the movable frames 1303 on both sides to move relative to each other, so that the rebar clamping claws 1306 can clamp or release the rebar synchronously, adapting to the clamping needs of rebars of different diameters.

[0027] Among them, a pair of sliding rods 1304 are slidably connected to the inner side of a pair of movable frames 1303. The two ends of the sliding rods 1304 are fixedly connected to the inner side of the first retainer 1302 respectively. Through the sliding rods 1304 slidably connected to the inner side of the movable frame 1303, the movable frame 1303 is guided to move only along the axial direction of the bidirectional threaded rod 1301, so as to avoid the movable frame 1303 rotating with the threaded rod and causing the steel bar clamp 1306 to tilt.

[0028] The height adjustment mechanism 14 includes a second one-way threaded rod 1401. The top end of the extension column 10 is provided with a threaded hole 1001. The outer side of the second one-way threaded rod 1401 engages with the inner side of the threaded hole 1001. The top end of the second one-way threaded rod 1401 is rotatably connected to a second retainer 1402. The two ends of the second retainer 1402 are respectively fixedly connected to the inner sides of the sleeve column 8. By engaging the second one-way threaded rod 1401 of the height adjustment mechanism 14 with the threaded hole 1001 of the extension column 10, the rotation of the threaded rod is converted into the vertical lifting and lowering of the extension column 10, thereby realizing the precise adjustment of the height of the rebar clamping mechanism 13.

[0029] Among them, a fourth motor 1403 is installed at the top of one side of the sleeve 8. Both the output end of the fourth motor 1403 and the top of the second one-way threaded rod 1401 are fitted with bevel gears 1404. The fourth motor 1403 and the second one-way threaded rod 1401 are connected by bevel gears 1404. By meshing the fourth motor 1403 with the bevel gears 1404 at the top of the second one-way threaded rod 1401, the direction of power is reversed, and the horizontal output force of the motor is converted into the vertical rotational force of the threaded rod.

[0030] Specifically, the working principle of this automatic rebar placement device for precast components is as follows: During use, the gantry frame 1 and the crossbeam 2 form a stable frame, providing rigid support for the rebar placement and preventing deformation during operation. The wheel seats 3, wheel axles 4, and traveling wheels 5 work together to move the entire device along the track 7, achieving a wide-range placement across the precast platform. The first motor 6 drives the traveling wheels 5, replacing manual pushing and reducing labor intensity. The sliding opening 101 provides a moving channel for the sleeve column 8, cooperating with the translation mechanism 9 to achieve precise lateral movement of the sleeve column 8. The sleeve column 8 slides against the extension column 10, and the height of the rebar clamping mechanism 13 is adjusted using the height adjustment mechanism 14. The system adapts to the placement requirements of rebars in precast components of varying thicknesses. An electric turntable 11 drives the connecting plate 12 to rotate, enabling multi-angle rebar placement. A rebar clamping mechanism 13 stably grips the rebars, preventing them from falling off during placement. The first one-way threaded rod 901 of the translation mechanism 9 cooperates with the retaining seat 902 to ensure stable rotation of the threaded rod. A second motor 905 drives the first one-way threaded rod 901, causing the movable block 903 and the sleeve column 8 to move laterally, achieving precise positioning of the rebars in the lateral direction of the precast platform and avoiding positional deviations during manual placement. Limiting rods 904, slidably connected to both sides of the movable block 903, guide it to move only along a straight line. To prevent the movable block 903 from rotating with the first unidirectional threaded rod 901 and causing the sleeve 8 to shift, the bidirectional threaded rod 1301 of the rebar clamping mechanism 13 cooperates with the first retainer 1302 to ensure stable rotation of the threaded rod. The bidirectional threaded rod 1301 is driven by the third motor 1305, causing the two movable frames 1303 to move relative to each other, allowing the rebar clamping gripper 1306 to simultaneously clamp or release the rebar, adapting to the gripping needs of rebars of different diameters. The sliding rod 1304, slidably connected to the inner side of the movable frame 1303, guides the movable frame 1303 to move only along the axial direction of the bidirectional threaded rod 1301, preventing the movable frame 1303 from rotating with the threaded rod and causing the rebar clamping gripper to shift. The 1306 is tilted, and the second one-way threaded rod 1401 of the height adjustment mechanism 14 engages with the threaded hole 1001 of the extension column 10, converting the rotation of the threaded rod into the vertical lifting and lowering of the extension column 10, thereby achieving precise adjustment of the height of the rebar clamping mechanism 13. The fourth motor 1403 engages with the bevel gear 1404 at the top of the second one-way threaded rod 1401 to achieve the direction of power change, converting the horizontal output force of the motor into the vertical rotational force of the threaded rod. This utility model can effectively realize the automatic and high-precision placement of rebar in precast components, replacing manual placement of each rebar. It is suitable for industrial production scenarios of precast components such as composite slabs and shear walls, and has high practical value.
