Description

Technical Field

[0001] This invention belongs to the field of cap beam reinforcement technology, specifically relating to automatic shearing and bending machinery for cap beam reinforcement and reinforcement position control frame. Background Technology

[0002] A cap beam is a horizontal beam installed on top of a pier or pile frame to support, distribute, and transfer the load of the superstructure. It is also called a cap beam. It is a reinforced concrete or lightly reinforced concrete horizontal beam installed on the pier (apron) or pile frame. Its main function is to support the superstructure of the bridge and transfer all the load to the substructure. Some bridge piles are directly connected to the cap beam, while others are connected to the column first and then to the cap beam. The cap beam is located in the middle of the pile foundation beam-slab structure, playing a crucial role in connecting the upper and lower sections. To improve the overall performance of the cap beam, a cap beam reinforcement cage is often used. The cap beam reinforcement cage is made by binding and welding various pre-formed steel bars. It is necessary to process the unprocessed steel bars into pre-formed steel bars. Currently, pre-formed steel bars are transported, cut, and bent manually. This method has problems such as slow processing speed, poor accuracy, and high cost. In addition, due to the complex structure and variety of cap beam reinforcement cages, quality problems such as steel bar misalignment, positional deviation, and uneven spacing are prone to occur during steel bar installation. During welding, uneven temperature can occur due to high temperatures, prolonged natural stacking, and uneven stress during hoisting, leading to deformation of the reinforcement cage. Therefore, it is very necessary to provide a simple structure, mechanized automatic transport, automatic cutting, automatic bending, and versatile automatic steel bar automatic cutting and bending machine and steel bar position control frame for cap beams that can achieve steel bar positioning.

[0031] The present invention will now be further described with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figure 1-11 As shown, the automatic shearing and bending machine for cap beam reinforcement and the reinforcement position control frame include a processing device and a position control frame. The processing device includes a power system, a hydraulic system, a reinforcement conveying system, a shearing system, a semi-finished reinforcement conveying system, a bending system, and a control system. The control system includes control elements and operating switches. The position control frame includes a left mold frame 101, a right mold frame 102, a horizontal connection system 103, and a vertical connection system 104.

[0034] In this embodiment, the power system includes an electric motor, a gearbox, a transfer case, a hydraulic motor, and a hydraulic pump. The electric motor provides power to the rebar conveying system, shearing system, semi-finished rebar conveying system, bending system, and control system. The hydraulic system includes a hydraulic motor, a hydraulic pump, hydraulic pipes for conveying oil, and hydraulic valves for controlling the flow direction of the oil or adjusting its pressure and flow rate. The control system consists of control elements and operating switches. Through the control system, rebar conveying, rebar fixing and loosening, rebar shearing, semi-finished rebar conveying, adjustment of the folding head position, bending, and other operations can be completed.

[0035] The rebar conveying system includes a push plate 6 and a slide rod 7. A fixed plate 67 is provided on the left side of the push plate 6. The fixed plate 67 has plate holes 66 on both the upper and lower sides. Push rods 68 are provided inside the plate holes 66. One end of the push rod 68 passes through the plate hole 66 and through the fixed plate 67, and the other end is connected to the push plate 6. Push springs 69 are sleeved on the part of the push rod 68 between the fixed plate 67 and the push plate 6. A camshaft 14 is provided on the left side of the push plate 6. A cam 13 is provided on the outside of the camshaft 14. A set of slide rods 7 is provided on the right side of the push plate 6. A groove 65 is provided at the lower end of the slide rod 7. The rebar 8 slides into the groove 65 through the slide rod 7 and can slide left and right in the groove 65. Two sets of conveying wheel shafts 63 are provided on the right side of the slide rod 7. Conveying wheels 64 are provided on the outside of the conveying wheel shafts 63.

[0036] For better performance, the conveyor wheel 64 is made of high-elasticity, high-strength rubber material. The conveyor wheel 64 rotates to generate friction on the reinforcing bar 8 to transport the reinforcing bar 8. The conveyor wheel shaft 63 is a floating shaft. A first baffle 11 is provided above the conveyor wheel 64 on the upper right side of the slide rod 7. A shaft groove 10 is provided below the first baffle 11 corresponding to the conveyor wheel shaft 63. A conveying spring 9 is provided inside each shaft groove 10. The upper end of the conveying spring 9 is connected to the first baffle 11 and the lower end is connected to the conveyor wheel shaft 63. The conveyor wheel shaft 63 can slide in the shaft groove 10. When the diameter of the reinforcing bar 8 changes, the distance between the conveyor wheels 64 can be automatically adjusted under the elastic force of the conveying spring 9 to adapt to the conveying of reinforcing bars 8 of different diameters.

[0037] In this embodiment, the working principle of the rebar conveying system is as follows: the unprocessed rebar slides into the slide groove 65 via the slide bar 7, the hydraulic pump drives the cam shaft 14 to rotate, which in turn drives the cam 13 to rotate. The large radius cam 13 drives the push plate 6 to move to the right, and the push plate 6 pushes the rebar 8 to move to the right. The hydraulic pump drives the conveying wheel shaft 63 to rotate, which in turn drives the conveying wheel 64 to rotate. When the rebar 8 reaches the middle of the front and rear conveying wheels 64, the rotation of the conveying wheel 64 generates friction on the rebar 8 to complete the conveying of the rebar 8. The use of two sets of conveying wheels 64 can ensure that the rebar 8 remains straight during conveying.

[0038] The shearing system includes a frame 18, inside which is a frame slide groove 19. A slider 17 is installed inside the frame slide groove 19 and can slide left and right along the frame slide groove 19. An adjusting plate 20 is installed at the lower end of the slider 17. A second baffle 22 is installed on the right side of the adjusting plate 20. A screw 24 is installed inside the second baffle 22. The left end of the screw 24 is connected to the adjusting plate 20, and the right end is connected to an adjusting nut 23. A first screw spring 21 is sleeved between the adjusting plate 20 and the second baffle 22 on the outside of the screw 24. A moving plate 16 and a fixed plate 62 are respectively installed on the upper and lower sides of the left side of the adjusting plate 20. A hydraulic cylinder 15 is installed above the moving plate 16, and a shear 12 is installed to the left of the hydraulic cylinder 15.

[0039] The scissors 12 include a handle 121, a head 122, a shaft 123, and a spring 124. The scissors 12 has handles 121 on both the left and right sides. The spring 124 is located inside the handle 121. The head 122 is located below the handle 121. The head 122, handle 121, and shaft 123 are connected by a lever structure to form the scissors 12. A cam shaft 14 is located on the right side of the handle 121. A cam 13 is located on the outside of the cam shaft 14 and fits against the handle 121.

[0040] In this embodiment, the shearing system functions to cut the unprocessed steel bars conveyed by the steel bar conveying system into semi-finished steel bars of a set length; the working principle of the shearing system is as follows:

[0041] 1) Cutting reinforcing bars

[0042] The hydraulic cylinder 15 retracts, causing the moving plate 16 to move forward, creating a gap between the moving plate 16 and the fixed plate 62 for the reinforcing bar 8 to pass through. The unprocessed reinforcing bar is conveyed to the right by the reinforcing bar conveying system, passing through the gap between the moving plate 16 and the fixed plate 62 and continuing to the right until it reaches the adjusting plate 20 and stops conveying. The hydraulic cylinder 15 extends, causing the moving plate 16 to move, so that the moving plate 16 and the fixed plate 62 clamp and fix the reinforcing bar 8. The hydraulic pump drives the camshaft 14 to rotate, which in turn drives the cam 13 to rotate. The large radius cam 13 drives the shear handle 121 to engage inward to complete the shearing of the reinforcing bar 8. After the reinforcing bar is sheared, the hydraulic cylinder 15 retracts, causing the moving plate 16 to move, so that the fixing of the reinforcing bar by the moving plate 16 and the fixed plate 62 is released. The sheared semi-finished reinforcing bar falls under its own weight and enters the semi-finished reinforcing bar conveying system.

[0043] 2) Adjust the processing length of the reinforcing bars

[0044] Rotating the adjusting nut 23 clockwise will cause the screw 24 to move to the right, and under the elastic force balance of the first screw spring 21, it will cause the adjusting plate 20 to move to the right, increasing the processing length of the steel bar; rotating the adjusting nut 23 counterclockwise will cause the screw 24 to move to the left under the elastic force of the first screw spring 21, and will cause the adjusting plate 20 to move to the left, decreasing the processing length of the steel bar.

[0045] The semi-finished steel bar conveying system includes a guide plate 61 and a conveying plate 47. The guide plate 61 is equipped with a damping block 71 to reduce the falling speed of the semi-finished steel bars and reduce the impact on the conveying plate 47. The left side of the conveying plate 47 is equipped with a top plate 60 for pushing the semi-finished steel bars to the right. The conveying plate 47 is equipped with a horizontal gear 48 and a vertical gear 57 that are perpendicular to each other. The vertical gear 57 is equipped with a shaft slide 59. The vertical gear 56 is equipped with a longitudinal circular gear 56 at the meshing point below the vertical gear 57. The longitudinal circular gear 56 is connected to the shaft slide 59 through a longitudinal circular gear shaft 58. The horizontal gear 48 is equipped with a front circular gear 49 and a rear circular gear 55 at the meshing points on the left and right sides respectively. The front circular gear 49 and the rear circular gear 55 are equipped with a shaft plate 51 on their inner sides. The front circular gear 49 and the rear circular gear 55 are connected to the shaft plate 51 through a front circular gear shaft 50 and a rear circular gear shaft 54 ​​respectively.

[0046] A base plate 53 is provided below the shaft plate 51. The base plate 53 has screw holes 46 inside, and bolts 52 are installed inside the screw holes 46. The guide plate 61 includes front and rear guide plates 61 and a slide formed by the front and rear guide plates 61. The semi-finished steel bars cut by the shearing system fall under their own weight and enter the slide formed by the front and rear guide plates 61, and then fall into the groove opened above the conveying plate 47.

[0047] In this embodiment, the function of the semi-finished steel bar conveying system is to transport the sheared semi-finished steel bars to the bending system; the working principle of the semi-finished steel bar conveying system is as follows:

[0048] 1) Semi-finished steel bar conveying

[0049] The hydraulic pump drives the front spur gear 49 and the rear spur gear 55 to rotate clockwise. Since the front spur gear 49 and the rear spur gear 55 mesh with the horizontal gear 48, the clockwise rotation of the front spur gear 49 and the rear spur gear 55 drives the horizontal gear 48 to move to the right, which in turn drives the conveying plate 47 to move to the right. After reaching the position set by the bending system, the conveying plate 47 stops, thus realizing the conveying of semi-finished steel bars. After the conveying is completed, the hydraulic pump drives the front spur gear 49 and the rear spur gear 55 to rotate counterclockwise, which drives the conveying plate 47 to move to the left. The conveying plate 47 stops when it reaches the initial position, and then the next conveying is carried out.

[0050] 2) Adjustment of front and rear conveyor positions

[0051] The hydraulic pump drives the longitudinal circular gear 56 to rotate. Due to the meshing of the longitudinal flat gear 57 and the longitudinal circular gear 56 under the action of the shaft slide 59, the rotation of the longitudinal circular gear 56 drives the longitudinal flat gear 57 to rotate forward and backward, which in turn drives the conveyor plate 47 to move forward and backward, thereby realizing the adjustment of the forward and backward conveying position.

[0052] 3) Adjustment of upper and lower conveyor positions

[0053] Rotating bolt 52 can drive shaft plate 51 to rise and fall, drive front spur gear 49 and rear spur gear 55 to rise and fall, drive conveyor plate 47 to rise and fall, and realize the adjustment of the upper and lower conveying positions.

[0054] The bending system includes a horizontal flat gear 25, with an upper spherical gear 29 at its meshing point. A shaft bracket 31 is located on the outer side of the upper spherical gear 29. The upper spherical gear 29 is connected to the shaft bracket 31 via an upper spherical gear shaft 30. A connecting plate 32 is located below the shaft bracket 31, and a connecting rod 33 is located below the connecting plate 32. An upper screw 35 and a lower screw 37 are sequentially arranged below the connecting rod 33. A second screw spring 36 is located inside both the upper screw 35 and the lower screw 37. The upper screw 35... Both the upper screw 35 and the lower screw 37 are provided with a first nut 34 on their outer sides. The upper screw 35 and the lower screw 37 are provided with a left flat gear 41 and a right flat gear 40 on their inner left and right sides, respectively. The left spur gear 44 and the right spur gear 40 are provided with a left spur gear 44 and a right spur gear 38 at their outer meshing points, respectively. The left spur gear 44 and the right spur gear 38 are provided with a shaft sleeve 43 behind them. The left spur gear 44 and the right spur gear 38 are connected to the shaft sleeve 43 through the left spur gear shaft 42 and the right spur gear shaft 39, respectively, and can slide up and down along the shaft sleeve 43.

[0055] The first bending mechanism 28 and the second bending mechanism 45, which are located inside the horizontal flat gear 25, are both equipped with a left bending head 27. The right side of the left bending head 27 is equipped with a right bending head 70. The left bending head 27 and the right bending head 70 are respectively installed on the left spherical gear shaft 42 and the right spherical gear shaft 39 of the corresponding bending mechanism through the corresponding telescopic device 26.

[0056] In this embodiment, the bending system functions to bend the cut semi-finished steel bars into three types of reinforcement: door bars, stirrups, and M-beams (the door bars are then welded into a horizontal reinforcement frame). The bending system consists of three identical bending mechanisms: a first bending mechanism, a second bending mechanism, and a third bending mechanism. These three bending mechanisms cooperate to complete the steel bar bending work. The working principle of the bending system is as follows:

[0057] 1) Adjust the left and right positions of the folding head

[0058] The hydraulic pump drives the upper spur gear shaft 30 to rotate, which in turn drives the upper spur gear 29 to rotate. Since the upper spur gear 29 meshes with the horizontal flat gear 25, the rotation of the upper spur gear 29 drives the upper spur gear shaft 30 to move left and right. The left and right movement of the upper spur gear shaft 29 drives the telescopic device 26 to move left and right. The left and right movement of the telescopic device 26 drives the left folding head 27 to move left and right, thereby realizing the adjustment of the bending system and the left and right positions of the left folding head 27.

[0059] 2) Adjusting the up and down position of the folding head

[0060] The hydraulic pump drives the left spur gear shaft 42 and the right spur gear shaft 39 to rotate, which in turn drives the left spur gear 44 and the right spur gear 38 to rotate. Since the left spur gear 44 meshes with the left flat gear 41 and the right spur gear 38 meshes with the right flat gear 40, the rotation of the left spur gear 44 and the right spur gear 38 drives the left spur gear shaft 42 and the right spur gear shaft 39 to slide up and down under the action of the shaft sleeve 43, thereby realizing the adjustment of the up and down positions of the left folding head 27 and the right folding head 70.

[0061] 3) Adjustment of the spacing between the left and right folds

[0062] Rotating the first nut 34, under the elastic force of the second screw spring 36, can adjust the distance between the left flat gear 41 and the right flat gear 40, thereby adjusting the horizontal distance between the left folding head 27 and the right folding head 70.

[0063] 4) Adjusting the working status of the folding head

[0064] The working principle is the same as that of telescopic device 26, so it will not be described again here.

[0065] The telescopic device 26 includes a sleeve seat 72, which is connected to the left spur gear shaft 42 and the right spur gear shaft 39. A sleeve 73 is provided on the right side of the sleeve seat 72, and a protective positioning plate 79 is provided on the right side of the sleeve 73. A sleeve spring 74 is provided inside the sleeve 73, with one end connected to the sleeve seat 72 and the other end connected to the left folding head 27. A lower positioning cylinder 75 and an upper positioning cylinder 78 are respectively vertically arranged on the upper and lower sides of the outer side of the sleeve 73. The lower positioning cylinder 75 and the upper positioning cylinder 78 are respectively provided with a lower positioning tongue 77, a lower positioning tongue spring 76, an upper positioning tongue 81, and an upper positioning tongue spring 80. The inner and outer ends of the lower positioning tongue spring 76 and the upper positioning tongue spring 80 are respectively connected to the lower positioning tongue 77, the lower positioning cylinder 75, the upper positioning tongue 81, and the upper positioning cylinder 78. The upper part of the left folding head 27 is provided with an arc-shaped positioning groove 83 corresponding to the lower positioning tongue 77 and the upper positioning tongue 87. The top of the left folding head 27 is provided with a cross groove 82.

[0066] In this embodiment, the working principle of the telescopic device 26 is as follows:

[0067] 1) Left-folding head not in working state

[0068] When the left folding head 27 is not in working condition, insert a Phillips head screwdriver into the Phillips head slot 82 and rotate the left folding head 27 90 degrees so that the (lower) arc-shaped positioning slot 83 of the left folding head 27 is aligned with the direction of the lower positioning cylinder 75. During the rotation, the upper positioning tongue 81 overcomes the elastic force of the upper positioning tongue spring 80 and leaves the (lower) arc-shaped positioning slot 83. The left folding head 27 is disengaged from the positioning of the upper positioning tongue 81 and is pressed down. When the (lower) arc-shaped positioning slot 83 of the left folding head 27 coincides with the position of the lower positioning tongue 77, the lower positioning tongue 77 moves inward under the elastic force of the lower positioning tongue spring 76 and enters the (lower) arc-shaped positioning slot 83, preventing the left folding head 27 from moving and completing the inward positioning of the left folding head 27. The left folding head 27 is then in a non-working state.

[0069] 2) Folding head working status

[0070] When the left folding head 27 is not in working condition, insert a Phillips head screwdriver into the Phillips head slot 82 and rotate the left folding head 27 90 degrees. The lower positioning tongue 77 overcomes the elastic force of the lower positioning tongue spring 76 and leaves the (lower) arc-shaped positioning groove 83. The left folding head 27 is disengaged from the positioning of the lower positioning tongue 77 and rises under the elastic force of the sleeve spring 75. At this time, the (upper) arc-shaped positioning groove 83 of the left folding head 27 is aligned with the direction of the upper positioning cylinder 78. When the (upper) arc-shaped positioning groove 83 of the left folding head 27 coincides with the position of the upper positioning tongue 81, the upper positioning tongue 81 moves inward under the elastic force of the upper positioning tongue spring 80 and enters the (upper) arc-shaped positioning groove 83, preventing the left folding head 27 from moving and completing the outward positioning of the left folding head 27. The left folding head 27 then enters the working state.
