[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0036] As shown Figure 1 in the figure, a subsea rubber pipeline cutting device includes a base 1, a shearing mechanism 2 is provided on the base 1, a bent pipe 3 is on the shearing mechanism 2, a cutting mechanism 8 is provided at the other end of the bent pipe 3 on the base 1, a track bracket 4 is further provided above the shearing mechanism 2 on the base 1, a sleeving assembly 5 is slidably provided on the track bracket 4, a receiving mechanism 9 is provided at the bottom end of the bent pipe 3 on the base 1, an adsorption mechanism 6 is further provided on the base plate, a transfer mechanism 7 is provided below the adsorption mechanism 6 on the base 1. During use, the bent pipe 3 is fixed by the shearing mechanism 2. After being fixed, one end of the rubber pipe sleeve is clamped and fixed by the sleeving assembly 5, and the clamped end is expanded outward so that its diameter is larger than the diameter of the bent pipe 3, and the rubber pipe sleeve is aligned with one end of the bent pipe 3. The sleeving assembly 5 is moved along the track through the track bracket 4, and the rubber pipe sleeve is sleeved outside the bent pipe 3. After sleeving is completed, the cutting mechanism 8 is used to cut off one end of the rubber pipe sleeve, and the shearing mechanism 2 is used to cut the other end. After shearing is completed, the receiving mechanism 9 rises to catch the bent pipe 3 and moves towards the adsorption mechanism 6. During the movement of the adsorption mechanism 6, the adsorption mechanism 6 descends to adsorb and fix the bent pipe 3. After the bent pipe 3 is adsorbed and fixed, it rises. During the rising process, the transfer mechanism 7 moves below the bent pipe 3, and the bent pipe 3 falls into the transfer mechanism 7 to transfer the bent pipe 3.

[0037] As shown Figure 2 in the figure, the shearing mechanism 2 includes a first mounting plate 201 fixedly provided on the base 1. A first rotating shaft 202 is rotatably provided on the first mounting plate 201. A first pulley 203 is coaxially rotatably provided on the first rotating shaft 202. A second mounting plate 204 is fixedly provided on the first mounting plate 201. A third mounting plate 208 is fixedly provided on the second mounting plate 204. A first motor 205 is fixedly provided on the second mounting plate 204. The first motor 205 is fixedly connected to the second mounting plate 204, and the first motor 205 drives the first rotating shaft 202 to rotate. A long rotating shaft 209 is rotatably provided on the third mounting plate 208. A second pulley 206 is coaxially and rotatably provided on the long rotating shaft 209. A first synchronous belt 207 is connected between the first pulley 203 and the second pulley 206. A third pulley 213 is coaxially and fixedly provided on the long rotating shaft 209. The second pulley 206 and the third pulley 213 are respectively located at both ends of the third mounting plate 208. A cylindrical block 210 is further fixedly provided at one end of the long rotating shaft 209. Grooves 211 are symmetrically opened on the cylindrical block 210. A plurality of springs are fixedly provided in both side grooves 211. The number of springs is any number greater than one. The top ends of the springs on both sides are fixedly provided with arc-shaped clamping plates 212. The cylindrical block 210 is inserted into one end inside the bent pipe 3, and it is fixed by the arc-shaped clamping plates 212 and the springs connected thereto.

[0038] As shown Figure 2As shown, a fourth mounting plate 218 is also fixedly provided on the base 1. A number of first sliding rods 219 are fixedly connected between the first mounting plate 201 and the fourth mounting plate 218. The number of the first sliding rods 219 is any number greater than two. The same L-shaped plate 220 is slidably provided on a number of the first sliding rods 219. A first cutting knife 221 is fixedly provided at the top end of the L-shaped plate 220, and a first rack 222 is fixedly provided at the end of the L-shaped plate 220. A fifth mounting plate 215 is also fixedly provided on the base 1. A second rotating shaft 216 is rotatably provided on the fifth mounting plate 215. A fourth belt pulley 214 is coaxially and fixedly provided on the second rotating shaft 216.

The first gear 217 and the first rack 222 are in meshing transmission.

[0039] During use, the first motor 205 operates to drive the first belt pulley 203 to rotate, drives the second belt pulley 206 to rotate through the first synchronous belt 207. The rotation of the second belt pulley 206 causes the cylindrical block 210 to rotate synchronously through the long rotating shaft 209. The cylindrical block 210 fixes the bent pipe 3 through the arc-shaped clamping plate 212 and the spring thereon, realizing the rotation of the bent pipe 3. The long rotating shaft 209 realizes the rotation of the fourth belt pulley 214 through the second synchronous belt 223. The fourth belt pulley 214 rotates synchronously with the first gear 217 through the second rotating shaft 216. The transmission between the first gear 217 and the first rack 222 realizes the movement of the L-shaped plate 220 and the first cutting knife 221 thereon towards the bent pipe 3 until they contact and squeeze the rubber hose sleeve on the bent pipe 3 (in this state, the first gear 217 moves to the end of the first rack 222, and the first gear 217 will no longer be meshed with the first rack 222 when it continues to rotate). As the bent pipe 3 continues to rotate, the first cutting knife 221 cuts the rubber hose sleeve, cutting off the rubber hose sleeve clamped by the sleeving assembly 5.

[0040] As Figure 3 shown, the track bracket 4 includes two vertical brackets 401 fixedly installed on the base 1. A bent track 402 is fixedly provided between the two vertical brackets 401. A track groove 403 is formed in the bent track 402. A second rack 404 is fixedly provided on the inner wall of the track groove 403. A bent sliding groove 405 is formed on the side of the bent track 402. As Figure 3 and Figure 4As shown, the sleeving component 5 includes a second gear 501. The second gear 501 is arranged in the track groove 403. The second gear 501 is in meshing transmission with the second rack 404. A kidney-shaped plate 502 is also slidably arranged on the bent track 402. The kidney-shaped plate 502 is rotatably connected to the second gear 501. Above the kidney-shaped plate 502, a fifth pulley 503 and a sixth pulley 504 are rotatably arranged. A third synchronous belt 506 is connected between the fifth pulley 503 and the sixth pulley 504. The fifth pulley 503 is fixedly connected to the second gear 501 and rotates coaxially with the second gear 501. A second motor 505 is fixedly arranged on the kidney-shaped plate 502. The second motor 505 is fixedly connected to the kidney-shaped plate 502. A connecting rod 507 is fixedly arranged on the kidney-shaped plate 502. A slider 508 is fixedly arranged on the connecting rod 507. The slider 508 is slidably connected to the bent sliding groove 405. A sixth mounting plate 509 is also slidably arranged at the bottom end of the bent track 402. The sixth mounting plate 509 is rotatably connected to the second gear 501. A first telescopic cylinder 510 is fixedly arranged on the sixth mounting plate 509. The output end of the first telescopic cylinder 510 is fixedly connected to a seventh mounting plate 511. An oil tank 514 is also fixedly arranged on the cylinder body of the first telescopic cylinder 510. A fuel pipe 515 is connected to the oil tank 514. A jack 516 is also fixedly arranged on the first telescopic cylinder 510 below the oil tank 514. The fuel pipe 515 is provided with an oil outlet, and the oil outlet can be inserted into the jack 516. First fixing brackets 512 are fixedly arranged on both sides of the seventh mounting plate 511. Second telescopic cylinders 513 are fixedly arranged on the first fixing brackets 512. As Figure 5 shown, mounting blocks 517 are fixedly arranged on the second telescopic cylinders 513 on both sides. A third rack 518 and a fourth rack 519 are slidably arranged on the mounting blocks 517. A third gear 520 is meshed between the third rack 518 and the fourth rack 519. A fourth motor 521 is connected to the third gear 520. The fourth motor 521 drives the third gear 520 to rotate, and the fourth motor 521 is fixedly connected to the seventh mounting plate 511. An inner clamping plate 522 is fixedly arranged at one end of the fourth rack 519. An outer clamping plate 523 is fixedly arranged at one end of the third rack 518. A rectangular groove 524 is also arranged on the outer clamping plate 523. The third gear 520 passes through the rectangular groove 524. In this embodiment, two outer clamping plates 523 and two inner clamping plates 522 are evenly arranged and have the same structure. Arc-shaped wiping plates 525 are clamped in the two inner clamping plates 522. Connecting holes are arranged on the arc-shaped wiping plates 525, and the connecting holes are connected to the oil outlets on the fuel pipe 515. The fuel pipe 515 conveys the lubricating oil in the oil tank 514 to the arc-shaped wiping plates 525. The arc-shaped wiping plates 525 are made of sponge and can adsorb the lubricating oil in the fuel pipe 515. The arc-shaped wiping plates 525 can also be removed. After removal, the fuel pipe 515 is inserted into the jack 516 to prevent the lubricating oil from dripping.

[0041] During use, the fourth motor 521 is driven to rotate the third gear 520. The rotation of the third gear 520 can achieve the opposite movement of the third rack 518 and the fourth rack 519, that is, one of the outer clamping plate 523 and the inner clamping plate 522 moves inward and the other moves outward. At this time, the rubber hose is sleeved between the outer clamping plate 523 and the inner clamping plate 522, and the movement of the outer clamping plate 523 and the inner clamping plate 522 is controlled until they fit against the inner and outer walls of the rubber hose sleeve, realizing the clamping of the rubber hose sleeve. After clamping, the outer clamping plate 523 and the inner clamping plate 522 on both sides are synchronously expanded outward through the second telescopic cylinder 513. The rubber hose sleeve is made of rubber and can undergo a certain degree of deformation, facilitating the sleeving of one end of the rubber hose sleeve into the bent pipe 3. Then, the overall movement of the sleeving assembly 5 is realized through the second gear 501. The movement trajectory of the sleeving assembly 5 matches the shape of the bent pipe 3. Before the rubber hose sleeve is sleeved, lubricating oil also needs to be applied to the surface of the bent pipe 3 with the arc-shaped wiping plate 525 to make the sleeving of the rubber hose sleeve easier. The specific lubricating oil application is as follows: the oil tank 514 supplies oil to the arc-shaped wiping plate 525, and through the second telescopic cylinder 513, the arc-shaped wiping plate 525 is clamped around the bent pipe 3, and its movement is coordinated with the track support 4 to finally apply the lubricating oil to the surface of the bent pipe 3. The first telescopic cylinder 510 realizes the up and down movement of the arc-shaped wiping plate 525, the outer clamping plate 523 and the inner clamping plate 522.

[0042] As Figure 6 shown, the material receiving mechanism 9 includes an installation groove 901, which is arranged on the base 1.

One end of the first threaded rod 903 is fixedly connected to a fifth motor. The rotation of the fifth motor drives the first threaded rod 903 to rotate to realize the movement of the bent material receiving groove 906, and the third telescopic cylinder 905 controls the change in the height of the bent material receiving groove 906.

[0043] As Figure 6 shown, the transfer mechanism 7 includes a fourth gear 704, which is coaxially and fixedly connected to the first threaded rod 903.

[0045] During use, when the rubber tube sleeve on the bending pipe 3 is sheathed and cut off, control the third telescopic cylinder 905 to raise the bending material receiving groove 906 and clamp the bending pipe 3. Then, the first threaded rod 903 rotates to drive the bending material receiving groove 906 to move towards the adsorption mechanism 6. As the first threaded rod 903 rotates, the fifth rack 705 meshes with the fourth gear 704 for transmission, and the material receiving platform 703 withdraws from below the adsorption mechanism 6. Then, the synchronous rotation of the fifth gear 610 is realized through the eighth pulley 612, the seventh pulley 611 and the fourth synchronous belt 613. The fifth gear 610 meshes with the sixth rack 607 to realize the downward movement of the adsorption head 604 until the adsorption head 604 contacts the bending pipe 3. Start the negative pressure mechanism 606 to achieve the negative pressure attraction of the adsorption head 604 to the bending pipe 3. After the attraction is completed, the adsorption head 604 drives the bending pipe 3 to move upward. At the same time, the material receiving platform 703 moves below the bending pipe 3, the bending material receiving groove 906 retracts to the initial position, the adsorption head 604 releases the bending pipe 3, and the bending pipe 3 drops onto the material receiving platform 703 for collection.

Fourth telescopic cylinders 802 are fixedly arranged at the tops of the two ninth mounting plates 801. The output ends of the two fourth telescopic cylinders 802 are both fixedly provided with back plates 803. The two back plates 803 can be spliced to form a complete circle. Half gears 804 are slidably arranged on the two back plates 803. The two half gears 804 are spliced to form a complete gear.

The sixth gear 806 meshes with the half gear 804 for transmission. A sixth motor 807 is also connected to the sixth gear 806. The sixth motor 807 is fixedly connected with the back plate 803.

[0047] During use, the fourth telescopic cylinder 802 controls the movement of two back plates 803. The two back plates 803 clamp the other end of the bent pipe 3. The second cutting knife 805 contacts and presses against the rubber hose sleeve at this end. The sixth motor 807 drives the sixth gear 806 to rotate. Finally, through the meshing of the sixth gear 806 and the half gear 804, the circular movement of the second cutting knife 805 is realized, and the rubber hose sleeve at the other end of the bent pipe 3 is cut.

[0048] A cutting method for a submarine rubber pipeline cutting device includes the following steps:

[0049] S1: First, fix the bent pipe 3 on the cylindrical block 210 through the spring and the arc-shaped clamping plate 212. Then, move the sleeving assembly 5 to the starting end of the bent pipe 3. Control the arc-shaped wiping plate 525 to descend through the first telescopic cylinder 510, and realize the wrapping of the arc-shaped wiping plate 525 around the bent pipe 3 through the second telescopic cylinder 513. Subsequently, control the sleeving assembly 5 to move on the track support 4 to smear lubricating oil on the surface of the bent pipe 3. Then, return the sleeving assembly 5 to the initial position. Subsequently, sleeved the rubber hose between the outer clamping plate 523 and the inner clamping plate 522, and control the movement of the outer clamping plate 523 and the inner clamping plate 522 until they fit against the inner and outer walls of the rubber hose to realize the clamping of the rubber hose. After clamping, synchronously expand the outer clamping plates 523 and the inner clamping plates 522 on both sides outward through the second telescopic cylinder 513, insert one end of the rubber hose into the bent pipe 3, and then realize the overall movement of the sleeving assembly 5 through the second gear 501. Finally, completely sleeve the rubber hose onto the bent pipe 3. Then, the sleeving assembly 5 releases the rubber hose and returns to the initial position;

[0050] S2: The fourth telescopic cylinder 802 controls the movement of two back plates 803. The two back plates 803 clamp the other end of the bent pipe 3. The second cutting knife 805 contacts and presses against the rubber hose sleeve at this end. The sixth motor 807 drives the sixth gear 806 to rotate. Finally, through the meshing of the sixth gear 806 and the half gear 804, the circular movement of the second cutting knife 805 is realized, and the rubber hose sleeve at the other end of the bent pipe 3 is cut.

[0051] S3: As Figure 9 and Figure 10As shown, the first motor 205 then drives the first pulley 203 to rotate, and drives the second pulley 206 to rotate through the first synchronous belt 207. The second pulley 206 rotates through the long shaft 209 to make the cylindrical block 210 rotate synchronously. The cylindrical block 210 fixes the bending tube 3 through the arc clamping plate 212 and the spring thereon to realize the rotation of the bending tube 3, and the long shaft 209 realizes the rotation of the fourth pulley 214 through the second synchronous belt 223. The fourth pulley 214 rotates synchronously with the first gear 217 through the second rotating shaft 216. The first gear 217 and the first rack 222 drive to realize the L-shaped plate 220 and the first cutting knife 221 thereon to move toward the bending tube 3 until they contact and squeeze the rubber tube sleeve on the bending tube 3. As the bending tube 3 continues to rotate, the first cutting knife 221 cuts the rubber tube sleeve, and cuts off the rubber tube sleeve clamped by the sleeve assembly 5.

[0052] S4: Figure 9 and Figure 11 As shown, when the rubber tube sleeve on the bending tube 3 is sheared, the third telescopic cylinder 905 is controlled to raise the bending material receiving trough 906 and clamp the bending tube 3, and then the first threaded rod 903 rotates to drive the bending material receiving trough 906 to move toward the adsorption mechanism 6. As the first threaded rod 903 rotates, the fifth rack 705 is meshed with the fourth gear 704 for transmission, and the material receiving platform 703 withdraws from the bottom of the adsorption mechanism 6, and then the fifth gear 6 is realized through the eighth pulley 612, the seventh pulley 611 and the fourth synchronous belt 613. 10 rotates synchronously, the fifth gear 610 and the sixth rack 607 are engaged to realize the downward movement of the adsorption head 604 until the adsorption head 604 contacts the bending tube 3, and the negative pressure mechanism 606 is started to realize the negative pressure attraction of the bending tube 3 by the adsorption head 604. After the attraction is completed, the adsorption head 604 drives the bending tube 3 to move upward, and at the same time the material receiving platform 703 moves to the bottom of the bending tube 3, and the bending material receiving groove 906 returns to the initial position, and the adsorption head 604 releases the bending tube 3, and the bending tube 3 falls to the material receiving platform 703 for collection.
