Description

Technical Field

[0001] The present invention relates to an automatic installation device for sealing rubber rings of plastic double-wall corrugated pipes, belonging to the technical field of installation of sealing rubber rings for corrugated pipes. Background Art

[0002] One end of a common plastic double-wall corrugated pipe is a flared end, and the other end is a socket end. Moreover, the radial dimension of the flared end is larger than that of the socket end. During use, on-site construction workers need to sleeved a sealing rubber ring on the socket end, and then insert and connect it to the flared end.

[0003] Since the hardness of the sealing rubber ring of the plastic double-wall corrugated pipe is relatively large (IRHD 60±5), it is difficult for on-site construction workers to install it. For corrugated pipes with a larger diameter, it is not easy for one person to sleeve it, and there are also problems such as incorrect installation positions and easy flipping of the rubber ring. Moreover, when the rubber ring is expanded, uneven axial tension causes different degrees of damage to the rubber ring, especially the sealing surface of the rubber ring, resulting in the failure of the entire pipeline's water tightness test and leaving a potential leakage hazard for the sewage project.

[0004] In summary, it is obvious that the existing technology has inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

Detailed implementation mode

[0021] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific implementation mode of the present invention will now be described with reference to the accompanying drawings.

[0022] As Figure 1-4 shown, the present invention provides an automatic installation device for plastic double - wall corrugated pipe sealing rubber rings, including a rubber ring assembly sub - assembly 1 and a rubber ring picking - up sub - assembly 2. The rubber ring picking - up sub - assembly 2 grabs a rubber ring from the rubber ring storage rack 3, then turns to the rubber ring assembly sub - assembly 1, and transfers the rubber ring to the rubber ring assembly sub - assembly 1. The rubber ring assembly sub - assembly 1 sets the rubber ring in the groove between two protruding wave crests on the outer wall of the corrugated pipe.

[0023] The rubber ring assembly sub - assembly 1 includes a rubber ring assembly frame 4. The rubber ring assembly frame 4 is a regular hexagon structure formed by connecting six equal - length square pipes end to end. A first telescopic assembly is installed on each square pipe, and a cylinder clamping assembly 9 is installed on each first telescopic assembly; The cylinder clamping assembly 9 includes a push - pull cylinder 10. The push - pull cylinder 10 is fixedly installed inside the installation cylinder 11. On both sides of the front end of the installation cylinder 11, a side plate 111 is fixedly installed respectively. Two claws 12 are arranged side by side on the inner sides of the two side plates 111. The outer ends of the two claws 12 extend towards each other to form a bending part 121. A rotating shaft 122 is arranged at the rear end of the claw 12. Both ends of the rotating shaft 122 are rotatably installed on the side plate 111; The front end of the piston rod of the push - pull cylinder 10 extends between the two side plates 111. On both sides of the piston rod of the push - pull cylinder 10, connecting rods 13 are symmetrically hinged. The front end of the connecting rod 13 is hinged to the rear end of the claw 12, and the rear end of the connecting rod 13 is hinged to the piston rod of the push - pull cylinder 10.

[0024] After the piston rod of the push-pull cylinder 10 retracts, the two clamping jaws 12 are brought together by two connecting rods 13, thereby grasping the rubber ring. The six clamping jaws 12 on the rubber ring assembly frame 4 jointly support and stretch the rubber ring. Then, after the corrugated pipe is moved forward in place, the piston rod of the push-pull cylinder 10 extends, and the two clamping jaws 12 separate, so that the rubber ring is sleeved in the groove between the two protruding wave crests on the outer wall of the corrugated pipe.

[0025] During the sleeving process, no manual assistance is required, and it is completely automated. The corrugated pipe is accurately conveyed forward through a feeding and conveying device (not shown in the figure). A positioning device is provided on the rubber ring assembly frame 4. After the positioning device accurately positions the forward and backward feeding amounts of the corrugated pipe, the rubber ring can be accurately installed in the specified groove on the outer wall of the corrugated pipe (one or more rubber rings are generally installed at the end of the corrugated pipe), preventing the rubber ring from being installed off-center.

[0026] There are various implementation manners of the positioning device. One of the implementation manners is to include a proximity sensor (not shown in the figure) installed on the rubber ring assembly frame 4. Through the electric control system setting, when the proximity sensor detects a wave crest on the outer wall of a certain corrugated pipe, the proximity sensor feeds back the detected number of wave crests to the electric control system, and the electric control system controls the feeding and conveying device to stop feeding, so as to ensure the accurate installation position of the rubber ring.

[0027] The first telescopic assembly includes a first fixing frame 5 slidably installed on the square pipe. The sliding direction of the first fixing frame 5 is perpendicular to the square pipe. The outer side of the first fixing frame 5 is fixedly connected to the mounting cylinder 11 of the cylinder clamping assembly 9. The first fixing frame 5 moves telescopically under the drive of the first telescopic drive assembly.

[0028] The first telescopic drive assembly includes a first straight rack 6, a first gear 7 and a first drive sprocket 8. The first straight rack 6 is fixedly installed on the side of the first fixing frame 5. The first gear 7 and the first drive sprocket 8 are coaxially fixedly connected, and the first gear 7 and the first drive sprocket 8 are rotatably installed on the square pipe. The first gear 7 meshes with the first straight rack 6 for transmission. The first gear 7 is installed on the front side of the square pipe, and the first drive sprocket 8 is installed on the rear side of the square pipe. An endless chain is in transmission cooperation with the outer sides of the six first drive sprockets 8 on the rubber ring assembly frame 4, as Figure 5 shown; a first transmission sprocket 14 is rotatably provided between two adjacent first drive sprockets 8. The first transmission sprocket 14 is arranged on the outer side of the endless chain, and the first transmission sprocket 14 is rotatably installed on the square pipe. One of the first transmission sprockets 14 is driven by a first motor 15.

[0029] The first motor 15 drives the annular chain to rotate, thereby driving the first drive sprockets 8 of all the first telescopic components to rotate simultaneously. Then, through the meshing transmission between the first gear 7 and the first straight rack 6, the telescopic component drives the cylinder clamping component 9 to expand and contract, so as to be able to adjust the size of the rubber ring being expanded, and thus be able to fit rubber rings of different diameters on the corrugated pipe, with better versatility. In addition, after the rubber ring picking unit 2 transfers the rubber ring, the first telescopic component can push the cylinder clamping component 9 to extend inward to grab the rubber ring.

[0030] The lower end of the rubber ring assembly frame 4 is installed on the moving bracket 16. The lower end of the moving bracket 16 is provided with a base 17, and a sliding rod 18 is installed at the upper end of the base 17. The moving bracket 16 is slidably installed on the sliding rod 18. A translation cylinder 19 is also installed at the upper end of the base 17, and the piston rod of the translation cylinder 19 is connected to the moving bracket 16. The translation cylinder 19 pushes the moving bracket 16 and the rubber ring assembly frame 4 on its upper end to slide back and forth relative to the base 17. After the rubber ring picking unit 2 transfers the rubber ring, the rubber ring assembly frame 4 moves forward to the position of the rubber ring under the push of the translation cylinder 19, so as to grab the rubber ring.

[0031] As Figure 6 , the rubber ring picking unit 2 includes a rubber ring picking frame 20, and the rubber ring picking frame 20 is a regular hexagon structure formed by connecting six equal-length square pipes end to end. A second telescopic component is installed on each square pipe, and a rubber ring hook 22 is installed on each second telescopic component.

[0032] The second telescopic component includes a second fixed frame 21 slidably installed on the square pipe. The sliding direction of the second fixed frame 21 is perpendicular to the square pipe. The outer end face of the second fixed frame 21 is fixedly connected to the rubber ring hook 22, and the second fixed frame 21 expands and contracts under the drive of the second telescopic drive component.

[0033] The second telescopic drive component includes a second straight rack 23, a second gear 24, and a second drive sprocket 25. The second straight rack 23 is fixedly installed on the side of the second fixed frame 21. The second gear 24 and the second drive sprocket 25 are coaxially fixedly connected, and the second gear 24 and the second drive sprocket 25 are rotatably installed on the square pipe. The second gear 24 meshes with the second straight rack 23 for transmission. The second gear 24 is installed on the front side of the square pipe, and the second drive sprocket 25 is installed on the rear side of the square pipe. An annular chain is in transmission cooperation with the outside of the six second drive sprockets 25 on the rubber ring picking frame 20, as Figure 7 shown; A second transmission sprocket 35 is rotatably provided between every two adjacent second drive sprockets 25. The second transmission sprocket 35 is arranged on the outside of the annular chain, and the second transmission sprocket 35 is rotatably installed on the square pipe. One of the second transmission sprockets 35 is driven by a third motor 37.

[0034] The telescoping principle of the second telescoping component is the same as that of the first telescoping component, which will not be elaborated here.

[0035] As Figure 8 , the rubber ring grab hook 22 includes a vertical long side 221 and a horizontal short side 222 that are perpendicularly connected. The vertical long side 221 is installed on the outer surface of the second fixing frame 21. A card slot 223 is provided at the outer end of the horizontal short side 222, and the opening direction of the card slot 223 faces the outside of the rubber ring picking frame 20.

[0036] The rubber ring picking assembly 2 further includes a fixing frame 28, a sliding frame 26, and a rotating seat 29. A horizontal shaft 30 is fixedly provided at the lower end of the rubber ring picking frame 20. The horizontal shaft 30 is rotatably installed on the rotating seat 29. The rotating seat 29 and the sliding frame 26 are hinged to each other through a vertical shaft 31. The sliding frame 26 is installed on the fixing frame 28.

[0037] A vertical column 291 is vertically fixed on the rotating seat 29. An electric push rod 34 is installed at the top of the vertical column 291. As Figure 7 , a C-shaped steel channel 36 is radially fixed along the middle position of the horizontal shaft 30. The upper end of the electric push rod 34 is hinged to the top of the vertical column 291, and the lower end of the piston rod of the electric push rod 34 is hinged to the C-shaped steel channel 36; an angle adjustment cylinder 33 is also installed on the sliding frame 26. The rear end of the angle adjustment cylinder 33 is hinged to the sliding frame 26, and the piston rod of the angle adjustment cylinder 33 is hinged to the rotating seat 29.

[0038] The electric push rod 34 drives the rubber ring picking frame 20 to flip 90 degrees relative to the rotating seat 29. When picking up the rubber ring from the rubber ring storage rack 3, the electric push rod 34 pushes the rubber ring picking frame 20 to be in a horizontal state, and then pushes the rubber ring picking frame 20 to be in a vertical state to facilitate the transfer of the rubber ring to the rubber ring assembly unit; the angle adjustment cylinder 33 pushes the rotating seat 29 and the rubber ring picking frame 20 to rotate horizontally. After the rubber ring picking assembly 2 finishes picking up the rubber ring, the angle adjustment cylinder 33 drives the rubber ring picking frame 20 to rotate horizontally so that the vertical end face of the rubber ring picking frame 20 is parallel to the vertical end face of the rubber ring assembly frame 4.

[0039] The fixing frame 28 includes a bottom frame and a gantry 281 vertically installed on the bottom frame. The sliding frame 26 is slidably installed on the gantry 281 through a slide rail. A lead screw 27 is vertically rotatably installed on the gantry 281. The lead screw 27 is driven by a second motor 32. A nut is installed on the sliding frame 26, and the nut is in threaded transmission with the lead screw 27. When the second motor 32 drives the lead screw 27 to rotate, the sliding frame 26 and the rubber ring picking frame 20 are driven to slide up and down through threaded transmission, so that the up and down positions of the rubber ring picking frame 20 correspond to those of the rubber ring assembly frame 4, thereby enabling the rubber ring to be completely automatically transferred from the rubber ring picking assembly 2 to the rubber ring assembly unit 1.

[0040] When the rubber ring picking sub-assembly 2 is working, the electric push rod 34 pushes the rubber ring picking frame 20 to be in a horizontal state. The second telescopic assembly drives the rubber ring hook 22 to expand outwards, lifts a rubber ring on the rubber ring storage rack 3, and then pushes the rubber ring picking frame 20 to be in a vertical state; the angle adjustment cylinder 33 then pushes the rotating seat 29 and the rubber ring picking frame 20 to rotate horizontally, so that the vertical end face of the rubber ring picking frame 20 is parallel to the vertical end face of the rubber ring assembling frame 4; when the upper and lower positions of the rubber ring picking frame 20 and the rubber ring assembling frame 4 do not correspond, the driving lead screw 27 rotates to drive the rubber ring picking frame 20 to slide up and down, so as to ensure that the height of the rubber ring picking frame 20 is exactly the same as that of the rubber ring assembling frame 4, and the end faces of the two are parallel, so as to ensure that the rubber ring can be completely automatically transferred from the rubber ring picking sub-assembly 2 to the rubber ring assembling sub-assembly 1, with a high success rate of rubber ring transfer, completely replacing manual operation.

[0041] After the rubber ring picking sub-assembly 2 transfers the rubber ring, the rubber ring assembling frame 4 moves forward under the push of the translation cylinder 19, so that the rubber ring assembling frame 4 is butted against the rubber ring picking frame 20. The first telescopic assembly can push the cylinder clamping assembly 9 to extend inwards to grab the rubber ring; after the corrugated pipe is conveyed in place through the feeding and conveying device, the cylinder clamping assembly 9 releases the rubber ring, so that the rubber ring is automatically and accurately sleeved in the corresponding groove on the outer wall of the corrugated pipe, and there will be no phenomenon of rubber ring flipping.

[0042] In addition, both the rubber ring assembling frame 4 and the rubber ring picking frame 20 are hexagonal structures composed of square pipes. When the rubber ring picking sub-assembly 2 picks up the rubber ring, the rubber ring is supported by six rubber ring hooks 22. When the rubber ring assembling sub-assembly 1 installs the rubber ring, the rubber ring is supported by six cylinder clamping assemblies 9. The six points support the rubber ring and expand the rubber ring into a regular hexagon, so that the circumferential force of the rubber ring is uniform, avoiding damage to the rubber ring, and finally making the rubber ring have good sealing quality and ensuring the smooth passage of the entire pipeline water tightness test.

[0043] The above is an example of the best implementation mode of the present invention, and the parts not described in detail are all common knowledge of those skilled in the art. The protection scope of the present invention is subject to the content of the claims, and any equivalent transformation based on the technical inspiration of the present invention is also within the protection scope of the present invention.
