Description

Technical Field

[0001] The present invention relates to the technical field of concrete pipe pile manufacturing, and more specifically, to a cloth feeding device for manufacturing energy-saving large-diameter cast-in-place prestressed concrete steel pipe piles. Background Art

[0002] Before casting the existing prestressed concrete steel pipe piles, a steel cage needs to be tied with multiple steel bars and wire first. During casting, the steel cage is placed into the mold, and then the concrete is poured downward through a cloth feeding device and the cloth feeding device is driven to move along the mold to complete the casting.

[0003] However, when the existing cloth feeding device is feeding the material, the concrete poured downward is relatively concentrated. Since the cloth feeding device is usually located directly above the mold, the poured concrete is usually concentrated in the middle of the mold. However, due to the small area of the through holes on the surface of the steel cage, the concrete concentrated in the middle is likely to accumulate on the surface of the steel cage, resulting in the accumulated concrete being difficult to enter the steel cage and easy to fall out. Moreover, subsequently, manual labor with a shovel is required to press the accumulated concrete into the steel cage. Although the problem can be effectively solved by dispersing the poured concrete, the dispersed concrete is likely to stick to the baffle of the cloth feeding device. Over time, the concrete will block the inner wall of the baffle, and since the inner wall of the baffle of the cloth feeding device is in a position that is not easy to clean, it will affect the casting effect of the concrete. Summary of the Invention

[0033] Please refer to Figures 1-12 , the present invention provides a technical solution: a cloth-feeding device for manufacturing energy-saving large-diameter cast-in-situ prestressed concrete steel pipe piles, including a frame 1, the frame 1 is located above the steel reinforcement cage, and a material cylinder 3 is fixedly connected to the frame 1 through a first support 2, and a blanking mechanism is provided at the bottom of the material cylinder 3;

[0034] The blanking mechanism is used to put the concrete in the material cylinder 3 into the steel reinforcement cage in the mold in a left-right dispersed manner;

[0035] A baffle mechanism is provided at the bottom of the frame 1, and the baffle mechanism is used to block the dispersed concrete and guide the dispersed concrete into the steel reinforcement cage when the blanking mechanism is discharging materials;

[0036] The baffle mechanism includes two groups of front baffle assemblies 21 distributed at the front and rear positions inside the frame 1 and two groups of side baffle assemblies 22 distributed at the left and right positions; both the front baffle assembly 21 and the side baffle assembly 22 are composed of a plurality of mutually attached strip-shaped plates 4, and the strip-shaped plates 4 at both sides of the front baffle assembly 21 and the side baffle assembly 22 are attached to the frame 1; a reciprocating mechanism is provided on both the front baffle assembly 21 and the side baffle assembly 22, and the reciprocating mechanism is used to drive the adjacent strip-shaped plates 4 on the front baffle assembly 21 and the side baffle assembly 22 to reciprocate alternately;

[0037] A driving mechanism is provided on the frame 1, and the driving mechanism is used to drive the blanking mechanism and the reciprocating mechanism to operate simultaneously;

[0038] During operation, when producing prestressed concrete pipe piles, the prefabricated steel reinforcement cage needs to be placed in the mold first, and then the mold is moved to the bottom position of the frame 1. At this time, concrete is put into the hopper 3, and the driving mechanism is started. The driving mechanism will drive the feeding mechanism to operate, and the feeding mechanism will put the concrete in the hopper 3 into the steel reinforcement cage in a dispersed manner; since there are many steel wires distributed on the surface of the steel reinforcement cage, compared with the direct pouring method of concrete, the concrete is concentrated in one place and is likely to accumulate and block on the surface of the steel reinforcement cage. By the dispersed pouring method, the concrete can be dispersed and enter through more entrances on the steel reinforcement cage, which can solve the problem of reducing the blockage and accumulation of concrete on the steel reinforcement cage.

[0039] Since the feeding mechanism feeds in a dispersed manner, the dispersed concrete is likely to fall outside the steel reinforcement cage. The two front baffle components 21 and the two side baffle components 22 on the frame 1 can limit the falling concrete and prevent it from falling outside; since the concrete will hit the front baffle components 21 and the side baffle components 22, it will accumulate on their surfaces over time, which will affect the feeding effect of the concrete; while driving the feeding mechanism to feed, the driving mechanism will also drive the reciprocating mechanism to operate. The reciprocating mechanism on the front baffle components 21 and the side baffle components 22 will drive the adjacent two strip plates 4 to move alternately when operating. When the strip plate 4 moves, the adjacent strip plate 4 will remain stationary. Under the action of the stationary strip plate 4, the concrete on the moving strip plate 4 will be pushed down; the continuous reciprocating movement of the adjacent two strip plates 4 can automatically clean the concrete adhered to the front baffle components 21 and the side baffle components 22.

[0040] As a further solution of the present invention, the reciprocating mechanism includes two frames 5 slidably connected to the frame 1; the two adjacent strip plates 4 on the front baffle components 21 and the side baffle components 22 are respectively fixedly connected to the two frames 5; on the frame 1, gears 6 are rotatably connected to both sides of the two frames 5 on the same side. The gears 6 are engaged with racks 7 at the upper and lower positions, and the upper and lower racks 7 are respectively fixedly connected to the two frames 5.

[0041] During operation, refer to Figures 5-7 , by driving all the gears 6 on the frame 1 to rotate reciprocally, when the gears 6 rotate reciprocally, they will drive the two racks 7 engaged with them to move alternately reciprocally. The two racks 7 drive the two frames 5 to move alternately reciprocally, and the two frames 5 will drive a plurality of adjacent strip plates 4 to move alternately reciprocally.

[0042] As a further solution of the present invention, the blanking mechanism includes a hopper 8; the bottom of the barrel 3 is in the shape of a horizontal cylinder, and the upper part of the hopper 8 is in the shape of a horizontal semi-cylinder. The upper part of the hopper 8 is hermetically attached to the bottom of the barrel 3; through holes 9 with the same size and shape are provided in both the upper part of the hopper 8 and the bottom of the barrel 3; on the front and rear sides of the barrel 3, a second support 10 is symmetrically and fixedly connected. A third support 11 is rotatably connected to the second support 10, and the bottom end of the third support 11 is fixedly connected to the hopper 8; an adjusting component is provided in the barrel 3, and the adjusting component is used to adjust the size of the through hole 9 at the bottom of the barrel 3.

[0043] The adjusting component includes two discs 12 symmetrically arranged at the front and rear positions inside the barrel 3, and two baffles 13 are fixedly connected between the two discs 12;

[0044] The distance between the two discs 12 is equal to the width of the through hole 9 at the bottom of the barrel 3, and the distance between the two baffles 13 is equal to the length of the through hole 9 at the bottom of the barrel 3;

[0045] The lower end of the hopper 8 is in a shape that expands outwards; the rotation axis of the second support 10 and the third support 11 is located on the axis of the cylindrical part at the bottom of the barrel 3;

[0046] During operation, refer to Figures 9-12 , when the hopper 8 discharges materials, the driving mechanism will drive the third supports 11 on the front and rear sides to rotate back and forth relative to the second supports 10. The third supports 11 will drive the hopper 8 to swing left and right. When the hopper 8 discharges materials, the concrete can be scattered left and right, which can increase the area of concrete blanking; since the middle part inside the mold is deeper than the two side parts, and it is necessary to ensure that the concrete in the middle part inside the mold is in a piled state after blanking, therefore, when the hopper 8 swings left and right, the amount of materials discharged needs to be reduced, and when the hopper 8 swings towards the middle position, the amount of materials discharged needs to be increased; when the driving mechanism drives the hopper 8 to swing left and right, the upper side part of the hopper 8 will gradually reduce the flowable area of the through hole 9 at the bottom of the barrel 3; while the hopper 8 is swinging, the driving mechanism will drive the discs 12 inside the barrel 3 to rotate in a direction opposite to the swinging direction of the hopper 8. When the discs 12 rotate, they will drive the baffles 13 to block the through hole 9 at the bottom of the barrel 3, thereby further reducing the flow area of the through hole 9 at the bottom of the barrel 3, and further reducing the amount of concrete poured by the hopper 8.

[0047] As a further solution of the present invention, the driving mechanism includes two motors 14 symmetrically distributed at the front and rear positions of the barrel 3. The motor 14 is fixedly connected to the barrel 3, and the bottom end of the output shaft of the motor 14 is fixedly connected with a first bevel gear 15. The front and rear sides of the bottom of the first bevel gear 15 are both engaged with a second bevel gear 16. The two second bevel gears 16 are respectively rotationally connected to the barrel 3 and the second support 10. The part of the second bevel gear 16 connected to the barrel 3 located inside the barrel 3 is fixedly connected with the disc 12. The end of the second bevel gear 16 connected to the second support 10 is fixedly connected with the third support 11. A linkage assembly is provided on the third support 11 for driving all the gears 6 on the frame 1 to rotate synchronously when the third support 11 rotates relative to the second support 10.

[0048] During operation, refer to Figures 9-11 , when it is necessary to drive the third support 11 and the disc 12 to rotate, start the motor 14 to drive the first bevel gear 15 to rotate. The first bevel gear 15 will drive the two second bevel gears 16 engaged with it to rotate in opposite directions. The two second bevel gears 16 will respectively drive the disc 12 and the third support 11 to rotate.

[0049] As a further solution of the present invention, the linkage assembly includes a first pulley 17 fixedly connected coaxially with the third support 11. A belt 18 is provided on the first pulley 17. At the four corner positions of the frame 1, two meshing third bevel gears 19 are provided. The two third bevel gears 19 are respectively fixedly connected coaxially with the two gears 6 on the frame 1 close to them. At the end positions of the third bevel gears 19 located on the left and right sides of the frame 1, a second pulley 20 is fixedly connected coaxially. The belt 18 is simultaneously engaged with the first pulley 17 and the second pulleys 20 on the left and right sides.

[0050] During operation, refer to Figures 5-7 、 Figure 9 , when the third support 11 rotates, it will drive the first pulley 17 connected to it to rotate. The first pulley 17 will drive the two second pulleys 20 on the same side of the first pulley 17 on the frame 1 through the belt 18. When the second pulley 20 rotates, it will drive the third bevel gear 19 connected to it to rotate. The third bevel gear 19 will drive another third bevel gear 19 engaged with it to rotate. The two third bevel gears 19 will drive the two gears 6 close to the corner on the frame 1 to rotate. Under the action of a total of four second pulleys 20 before and after, the eight gears 6 on the frame 1 can be driven to rotate synchronously.
