[0002] Embankment protection is to protect the embankments along the coast or rivers to prevent them from being collapsed due to constant erosion. The protection of the embankment foot is particularly important in embankment protection. During the construction of the embankment protection structure, the protection of the embankment foot often requires operations in the water. Therefore, the use of prefabricated concrete solid feet can improve the speed and efficiency of the embankment protection structure construction. According to the different embankment construction conditions, the weight of the prefabricated concrete solid feet is also different, generally more than ten tons or even dozens of tons. The prefabricated solid feet are hoisted after they are completed at the construction site and meet the hoisting requirements. The prefabricated solid feet need to be embedded with prefabricated solid feet lifting rings, and the prefabricated solid feet lifting rings are fixedly connected to the prefabricated solid feet steel frame to improve the safety of the prefabricated solid feet during hoisting.

[0044] The working principle of the above technical solution is:

[0045] A prefabricated fixed foot lifting ring processing device comprises a workbench 1, a feeding mechanism 2 is arranged at one end of the workbench 1, a cutting mechanism 3 and a bending mechanism are arranged on the top surface of the workbench 1, the bending mechanism is arranged on the side of the cutting mechanism 3 away from the feeding mechanism 2, the bending mechanism comprises a first bending component 4 and a second bending component 5, the second bending component 5 is arranged on the first bending component 4, the first bending component is used to bend the main body 101 of the prefabricated fixed foot lifting ring, the second bending component is used to bend the bending part 102 of the prefabricated fixed foot lifting ring, the main body 101 of the prefabricated fixed foot lifting ring is an inverted U-shape, and the ends of the two legs of the main body 101 are provided with bending parts 102 bent toward the outside of the main body 101, and the bending direction of the bending part 102 is opposite to the bending direction of the U-shape.

[0046] After being straightened by the straightening wheel 8, the steel bar is conveyed to the workbench 1 by the feed wheel 9. The steel bar is located between the disc 13 and the bending mechanism. When the length of the steel bar reaches the set length, the feed wheel 9 stops rotating. At this time, the piston rod of the first hydraulic cylinder 19 extends, and the extrusion wheel 17 of the first bending assembly squeezes the steel bar onto the circumferential surface of the disc to fix the steel bar. The first hydraulic cylinder 19 stops, and then the cutting machine 12 is started and moved horizontally toward the steel bar along the cutting machine slide 11. The cutting machine 12 cuts the steel bar. After cutting the steel bar 100, the cutting machine returns to the initial position to prepare for the next cutting.

[0047] The feed wheel 9 is transmission connected with the power unit.

[0048] After the steel bars are cut, the first hydraulic cylinder 19 is started, and the piston rod of the first hydraulic cylinder 19 continues to extend. The two extrusion wheels 17 bend the steel bars into a U shape on both sides of the disc to form a prefabricated fixed foot lifting ring main body 101. Annular grooves can be set on the circumferential surfaces of the disc 13 and the extrusion wheels 17 to prevent the steel bars from slipping.

[0049] After the piston rod of the first hydraulic cylinder 19 extends to a set length, the first hydraulic cylinder 19 stops moving, and the second hydraulic cylinder 21 is started at this time. The piston rod of the second hydraulic cylinder 21 extends to push the push plate 22 to move, and the first racks 28 on the left and right sides of the push plate 22 are respectively meshed with the two first gears 23, and the first racks 28 drive the first gear 23 to rotate. An internal thread is arranged on the upper part of the shaft hole 27 of the first gear 23, and the internal thread is threadedly connected with the external thread on the threaded shaft 30. A limit block 36 is arranged on the lower part of the threaded shaft 30, and a vertical limit groove 35 is arranged in the center hole 34 of the roller shaft 16. The limit block 36 is slidably arranged in the limit groove 35. An annular groove 37 is arranged on the inner circumferential surface of the center hole 34 of the roller shaft below the limit groove 35, and the annular groove 37 is connected with the limit groove. When the first gear 23 rotates, the threaded shaft is affected by the first gear. The force of the wheel, due to the action of the limit block 36 and the limit groove 35 set at the lower part of the threaded shaft 30, the threaded shaft 30 can only move downward. When the limit block 36 on the threaded shaft 30 enters the annular groove 37 from the limit groove 35, the first rack 28 is disengaged from the first gear 23. At this time, the two rollers 33 are driven by the bending rod 32 to move downward to the inner side of the steel bar that has been bent into a U shape. The piston rod of the second hydraulic cylinder 21 continues to extend to push the push plate 22 to continue to move. The second rack 29 is engaged with the second gear 31. The second rack drives the bending rod to rotate through the second gear, and the bending rod drives the roller to rotate. The roller 33 squeezes the ends of the two legs of the U-shaped steel bar to bend the steel bar into a curved portion 102 bent outward. At this time, the extrusion wheel 17 plays a supporting role, so that the two ends of the steel bar are bent according to the outer circumferential surface of the extrusion wheel. After the bending of the prefabricated fixed foot lifting ring is completed, the piston rod of the second hydraulic cylinder is retracted, driving the bending rod to rotate back to the position before bending. When the second rack is disengaged from the second gear, the limit block 36 is aligned with the limit groove 35, and the piston rod of the second hydraulic cylinder continues to be retracted, the first rack is engaged with the first gear, and the first rack drives the first gear to rotate in the opposite direction, so that the threaded shaft moves upward, so that the lower end surface of the roller 33 is higher than the top of the steel bar. In the initial state, the lower end surface of the roller 33 is higher than the position of the top of the steel bar. The initial state refers to the state before the bending begins.

[0050] After the second hydraulic cylinder is retracted into place, the first hydraulic cylinder is retracted to make the first bending component return to the initial position, preparing for the next bending.

[0051] The upper and lower ends of the roller shaft 16 respectively penetrate through the lower plate 15 and the upper plate 41 of the U-shaped frame 14, and the upper end surface of the roller shaft 15 is on the same horizontal plane as the upper end surface of the upper plate 41 of the U-shaped frame 14. The roller shaft is fixedly connected to the upper plate 41 and the lower plate 15 of the U-shaped frame 14.

[0052] Advantages of the above technical solution:

[0053] In the prefabricated fixed-foot sling processing device of the present invention, the bending mechanism includes a first bending component and a second bending component. The second bending component is arranged on the first bending component. After the first bending component completes the bending in one direction, the second bending component directly performs the bending in the second direction. When processing the prefabricated fixed-foot sling, the bending can be completed at one time without the need to adjust the steel bar in the middle, with high bending efficiency and low cost.

[0054] In one embodiment, two chutes 38 are arranged in parallel along the width direction of the workbench 1 on the upper surface of the workbench. The chutes are symmetrically arranged on both sides of the disc 13. A slider is fixedly arranged on the lower surface of the lower plate of the U-shaped frame 14. The shape of the slider is adapted to the chute, and the slider is slidably arranged in the chute 38.

[0055] Working principle of the above technical solution: On the upper surface of the workbench 1, chutes 38 parallel to the width direction of the workbench are symmetrically opened on both sides of the disc 13. A slider is fixedly arranged on the lower surface of the lower plate of the U-shaped frame 14. The shape of the slider is adapted to the chute 38, and the slider is slidably arranged in the chute 38. The cross-sections of the chute 38 and the slider can be set as trapezoids.

[0056] Advantages of the above technical solution: By opening chutes parallel to the width direction of the workbench on the upper surface of the workbench 1, it can ensure that the U-shaped frame 14 is perpendicular to the steel bar during movement, preventing the extrusion direction of the first bending component from deviating when bending the steel bar.

[0057] In one embodiment, a positioning block 40 is arranged on the side of the top surface of the workbench 1 where the bending mechanism faces away from the cutting mechanism. The positioning block is located on the extension line of the movement of the steel bar.

[0058] Working principle and advantages of the above technical solution: A positioning block 40 is arranged on the side of the top surface of the workbench 1 where the bending mechanism faces away from the cutting mechanism. The positioning block is located on the extension line of the movement of the steel bar. When the steel bar reaches the set length, the positioning block blocks the steel bar to stop its movement.

[0062] The working principle and beneficial effects of the above technical solution: after the prefabricated fixed foot lifting ring processing device starts working, the controller controls the feed wheel power unit, and uses the feed wheel to rotate to transport the steel bar 100 to the workbench 1. When the front end of the steel bar contacts the pressure sensor on the positioning block, the pressure sensor receives the pressure of the steel bar and transmits the pressure signal to the controller. The controller controls the feed wheel power unit to stop so that the feed wheel no longer rotates. After the first bending component clamps the steel bar between the disc and the extrusion wheel, the controller controls the cutting machine to start and controls the cutting machine to move along the cutting machine slide toward the steel bar to cut the steel bar, and then controls the cutting machine to move away from the steel bar along the cutting machine slide, and turns off the cutting machine.
