Description

Technical Field

[0001] The present invention relates to the technical field of power pipe connection, and specifically, to a high-voltage power pipe connection device. Background Art

[0002] High-voltage power pipes are products with PE-modified polyethylene for hot dip coating or epoxy resin for internal and external coating. They have excellent corrosion resistance. At the same time, the coating itself has good electrical insulation, will not cause electrocorrosion, has low water absorption, high mechanical strength, small friction coefficient, can achieve the purpose of long-term use, and can effectively prevent the damage of plant roots and soil environmental stress, etc. Power pipes are buried underground and are facilities that sleeve the cables to protect them. Power pipes are processed in sections, and when laying, each section of the power pipe needs to be connected.

[0003] In the process of existing pipeline connection, such as the Chinese patent with the publication number CN217803386U, it discloses a hot melt butt joint device for MPP power pipes, including a bearing plate. A driving mechanism and a support rod are respectively arranged on the surface of the bearing plate. The driving mechanism includes a connecting cylinder. A groove is formed on the surface of the connecting cylinder. The inner wall of the groove is threadedly connected with a threaded rod. The lower end of the threaded rod is rotatably connected with a fixing plate. A pulley is arranged on the surface of the fixing plate. The upper surface of the bearing plate is fixedly connected with a support plate. A bidirectional threaded column is rotatably connected to the surface of the support plate. A sliding block is threadedly connected to the surface of the bidirectional threaded column. An installation block is fixedly connected to the upper surface of the sliding block. For this hot melt butt joint device for MPP power pipes, by setting the support rod, connecting cylinder, threaded rod, fixing plate, pulley and bearing plate, since the contact area between the bearing plate and the ground is large, the stability of the device during use can be ensured. In this way, while taking into account the advantage of the pulley being convenient for movement, the stability during the butt joint of the pipes can also be ensured.

[0004] However, in the prior art, mainly after the pipes are clamped and butted, the bidirectional threaded column is used to connect and fix the pipes. That is to say, at the same time, the pipes on both sides need to be moved closer to the middle and spliced together before the butt joint operation can be carried out. However, in the prior art, the length of a single power pipe is not fixed. For a relatively long power pipe, when clamping its end, the weight of the middle and rear sections is likely to affect the position of its end, resulting in misalignment (one high and one low) when the two are butted. At this time, a regional gap is generated between the misaligned butting interfaces, causing mud, sand, and water outside the pipe to enter the pipe. The protection effect on the internal cable disappears and the pipe is blocked at the same time. Summary of the Invention

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0017] 1. When the power tube penetrates through the middle between the crossed clamping rollers II and is erected on the clamping groove at the top of the moving ring, one end of the power tube is clamped by the clamping mechanism. As the inner threaded sleeve is pushed forward driven by the threaded rod, the power tube on this side will be pulled and pushed forward together, while the power tube on the other side is fixed in the second insertion cylinder and remains stationary. When the power tube clamped in the first insertion cylinder is pushed to the second insertion cylinder, the ends of the power tubes on both sides are made to contact each other, so that the contact during welding of the two ends of the power tubes is closer. At the same time, during the docking process, the weight at the rear end of the power tube will not affect the end, improving the docking accuracy and thus reducing the gap generated therebetween.

[0018] 2. When one side of the power tube is clamped and remains stationary in the second insertion cylinder, while the power tube on the other side is pushed forward with the moving ring, by using this method of one moving and one stationary for docking, the docking can be more accurate.

[0019] 3. By providing auxiliary clamping parts on both sides of the support base, after the power tube passes through, the power tube is in an overhead state with the support column. In this way, the force generated will not directly act on the power tube, and the external force received by the power tube will be greatly reduced, maintaining the stability of the power tube. Thus, during the docking operation, the sealing performance of the contact end of the power tube will be stronger, effectively avoiding the phenomenon of gaps being generated during docking.

A plurality of connecting columns 35 are provided on the left clamping plate 33 and the right clamping plate 34. An arc-shaped plate 36 is provided at one end of the connecting column 35 away from the left clamping plate 33 and the right clamping plate 34. A plurality of first clamping rollers 37 are provided on the side of the arc-shaped plate 36 away from the connecting column 35. Both sides of the first clamping roller 37 are connected to both sides of the arc-shaped plate 36 through arc-shaped frames 38. A spring 39 is sleeved on the connecting column 35.

The guide rods 40 penetrate through the right clamping plate 34. A gear plate 41 is inserted through the upper part of the left clamping plate 33 at the center below the guide rods 40. The right end of the gear plate 41 is fixed to the center of the lower part of the side of the right clamping plate 34. A second gear 42 meshing with the gear plate 41 is provided on the side of the left clamping plate 33 below the gear plate 41. An upper connecting shaft 43 is inserted through the middle of the second gear 42. First support columns 44 are provided at both ends of the upper connecting shaft 43. The bottoms of the first support columns 44 are respectively fixed to the top side of one side of the column 2. A lower connecting shaft is horizontally arranged below the first support columns 44. A first gear 45 meshing with the second gear 42 and the first half gear 14 is provided on the lower connecting shaft.

[0036] The semi-gear one 14 and the semi-gear two 15 respectively pass through from the lower side slots of the left clamping plate 33 and the right clamping plate 34. When the semi-gear one 14 is pushed, it will drive the meshing gear one 45 on the side to rotate, further driving the gear plate 41 to move. Since the right end of the gear plate 41 penetrates through the left clamping plate 33 and is fixed at the lower part of the side wall of the right clamping plate 34, that is to say, the left clamping plate 33 is fixed, while the right clamping plate 34 moves along with the gear plate 41. Through this moving method, the power tube passing through the middle will be clamped. The clamping roller one 37 will clamp the power tube. The clamping roller one 37 is movably connected, that is to say, the clamping roller one 37 can move according to the surface of the passing power tube. The clamping angle of the power tube is adjusted through the clamping roller one 37 to maintain the tightness of the clamping. The clamping roller one 37 is made of rubber material.

[0037] Meanwhile, the auxiliary clamping part includes a support column 46. Triangular plates 47 are arranged on both sides of the support column 46. The bottom of the triangular plate 47 is fixed at the corresponding end parts on the top side of the support seat 1. An inner ring 48 is arranged at the top of the support column 46. A first rotating ring 49 and a second rotating ring 50 are respectively arranged on both sides of the inner ring 48. A plurality of first supports 51 are arranged on the sides of the first rotating ring 49 and the second rotating ring 50 away from the inner ring 48. Second supports 52 are arranged in the middle between adjacent first supports 51 on both sides of the inner ring 48. A clamping roller two 53 is inserted between any first support 51 and the second support 52. The clamping roller two 53 is arranged in a crosswise manner on both sides of the inner ring 48; A convex block 54 is arranged on one side of the first rotating ring 49 and the second rotating ring 50. A connecting shaft 55 is horizontally arranged between the convex blocks 54. A connecting end is arranged on the connecting shaft 55. An air rod 56 is arranged at the bottom of the connecting end. A matching air cylinder 57 is arranged on the side of the air rod 56 away from the connecting end. A support plate 58 is arranged at the bottom of the air cylinder 57. Connecting side plates 59 are arranged on both sides of the support plate 58. A fixing plate 60 is arranged at the bottom of the connecting side plate 59. The bottom of the fixing plate 60 is fixed on the top of the support seat 1.

[0038] On both sides of the top of the support base 1, an identical auxiliary clamping portion is provided. In this way, the power tubes inserted from both sides will be clamped at their ends by the auxiliary clamping portions at this location. When the power tubes are butt-jointed, the power tubes can be kept from being misaligned under the influence of the weight at the rear end, maintaining the overall stability of the power tubes. Among them, a number of first supports 51 are provided on the outer sides of the first rotating ring 49 and the second rotating ring 50, and second supports 52 are provided on the side of the inner ring 48 between the first supports 51. Then, a second clamping roller 53 is inserted between each set of corresponding first supports 51 and second supports 52. The second clamping rollers 53 are arranged in a crosswise structure, so that a square clamping groove is formed in the middle of the four intersections of the second clamping rollers 53 on one side. The power tube passes through this square clamping groove. When the angles of the first rotating ring 49 and the second rotating ring 50 are rotated, the notch of the square clamping groove formed in the middle will change accordingly, thereby clamping and limiting the power tube passing through.

[0039] Among them, grooves are provided at both ends of the side of the inner ring 48, and ridges adapted to the grooves are provided on the inner walls of the first rotating ring 49 and the second rotating ring 50. With this kind of clamping by multiple second clamping rollers 53 in a crosswise manner, the power tube passing through is in an overhead state with respect to the inner ring 48. In this way, a fault-type support is formed between the power tube and the support base 1. When the end of the power tube is butt-welded, the erected power tube will not directly contact the external force, maintaining the stability of the support erection.

[0040] Detailed usage method and function of this embodiment:

[0041] First, insert the two power pipes to be docked into the square notch formed by the two clamping rollers 53 on both sides. The power pipe on the right passes through the second insertion cylinder 6 and exits from the central through-hole of the fixed ring 7. The power pipe on the left is placed on the top clamping groove 24 of the first support plate 18 and the moving ring 23, and at the same time passes through the first insertion cylinder 27. At this time, the drive motor 21 operates, the motor 21 drives the threaded rod 20 to rotate, and the threaded rod 20 drives the internally threaded sleeve 22 sleeved on the upper part to move. When the internally threaded sleeve 22 moves to the right, it pulls the moving ring 23 to the right through the connecting rod 30. The elbow pipe 25 on the side of the moving ring 23 presses against the arc-shaped support plate 26 to the right. Among them, the arc-shaped support plate 26 is clamped and fixed on the first insertion cylinder 27. When the arc-shaped support plate 26 moves to the right, the first insertion cylinder 27 will also be pushed to the right together. The first half-gear 14 and the second half-gear 15 on both sides of the side of the arc-shaped support plate 26 pass through the sleeve 4 and move to the right. The second half-gear 15 will drive the third gear 16 to rotate. After the third gear 16 rotates, it will drive the fourth gear 13 meshed above to rotate. The fourth gear 13 drives the gear ring 12 to rotate. The inner wall teeth of the gear ring 12 will drive the fifth gear 11 meshed with it to rotate. After the fifth gear 11 rotates, it drives the side rack 10 meshed on one side to rotate, and the slide plate 9 will slide in the chute 8. At this time, the slide plate 9 in the chute 8 will slide towards the middle at the same time, so that the suction cup 28 at the inner end of the slide plate 9 clamps the surface end of the power pipe inserted in the middle. At this time, the power pipe on the right will be limited.

[0042] Meanwhile, when the half gear 14 slides, it drives the meshing gear 45 on the side to rotate. The gear 45 drives the meshing gear 42 above to rotate. The gear 42 drives the gear plate 41 above to move. After the gear plate 41 moves to one side, it pulls the right clamping plate 34 towards the left clamping plate 33. The clamping roller 37 inside clamps the surface end of the power tube passing through it. In this way, the end of the power tube on the left side is limited and clamped. Then, it will move to one side along with the internal thread sleeve 22 on the threaded rod 20, pulling the power tube towards the second insertion cylinder 6 on the right side until the first insertion cylinder 27 and the second insertion cylinder 6 are close, and the power tubes inserted inside come into contact. At this time, the contacting ends will be closely attached, and finally, the two contacting ends of the power tubes will be welded to complete the docking operation. Among them, when the power tube passes through the clamping roller 53, a telescopic movement occurs between the driving cylinder 57 and the air rod 56. The air rod 56 pulls the connecting shaft 55 to move, and the connecting shaft 55 drives the first rotating ring 49 and the second rotating ring 50, causing the angles of the first rotating ring 49 and the second rotating ring 50 to rotate. Since the first support 51 is fixed on the side of the rotating ring, and the second support 52 is fixed on the side of the inner ring 48, the position of the second support 52 always remains unchanged, while the first support 51 changes its position along with the first rotating ring 49 or the second rotating ring 50. In this way, the angle formed between the intersecting clamping rollers 53 will change, and the power tube will be firmly clamped. The power tube and the support column 46 will be in an overhead state. When processing, if external factors cause vibration force, it will not directly act on the power tube, thus maintaining the stability of the power tube and preventing the power tube from being unable to closely contact the power tube at the other end due to various external factors, and avoiding the generation of gaps between the two during docking.

[0043] Through the above specific implementation manners, those skilled in the art of the described technical field can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementation manners. Based on the disclosed implementation manners, those skilled in the art of the described technical field can arbitrarily combine different technical features to achieve different technical solutions.
