Description

Technical Field

[0001] The present invention belongs to the technical field of cables, and particularly relates to a wear-resistant cable and its protection component. Background Art

[0002] A cable is a device for transmitting electrical energy or signals, usually composed of several or several groups of wires. At present, the laying methods of cables include direct burial laying, pipe laying, shallow trench laying, cable trench laying, tunnel laying, overhead laying, etc.

[0003] Among them, during pipe laying, since both ends of the pipe are exposed during cable laying, after the cable is pulled into the pipe, the cable may bring outside soil, sand and gravel into the pipe, resulting in the presence of soil, sand and gravel in the pipe. In this way, when pulling the cable, the surface of the cable is easily worn by soil, sand and gravel, etc.

[0004] In view of the above technical problems, the applicant has retrieved some prior arts. For example, the patent publication number is CN117116541B. Its main technical means is that by setting up devices such as wear-resistant strips, wear-resistant rings and wear-resistant sliders to cooperate with each other, before laying the cable into the underground pipe, the wear-resistant ring is sleeved on the surface. Through the sliding between the wear-resistant slider and the underground pipe, in the early stage of laying, the sliding between the wear-resistant slider and the underground pipe replaces the direct friction between the cable and the pipe. During this period, the closed cylinder combination block is driven to fit on the surface of the cable to drive away the sand and gravel. And in the later stage of laying, by combining multiple wear-resistant rings into a whole to form a complete sealing component, the surface of the entering cable is scraped to block the sand and gravel, so that the cable in the underground pipe directly slides with the wear-resistant ring and does not contact the sand and gravel, avoiding the friction of the sand and gravel on the outer surface of the cable, achieving the effect of protecting the outer surface of the cable. After the applicant's analysis, the disadvantages of this technical solution are as follows: When laying the cable, it is necessary to set up multiple wear-resistant rings around the cable to form a complete sealing component as a whole. This not only makes the operation cumbersome, but also the inside of the pipe is in a wet state. When the cable is pulled, this sealing component contacts the wet soil, sand and gravel. Since the wet soil, sand and gravel contain moisture, the particles will generate viscosity and form a coagulated state. These coagulated particles are not easy to be separated, resulting in the cable needing to overcome a greater adhesion force. This adhesion force will increase the traction resistance of the cable, causing the cable to be blocked greatly when being pulled, thus increasing the difficulty of cable laying. Summary of the Invention

[0005] The purpose of the present invention is to provide a wear-resistant cable and its protection component, aiming to solve the technical problem that in the prior art, the sealing component contacts the wet soil, sand and gravel, resulting in a large resistance when the cable is pulled, thus increasing the difficulty of cable laying.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] 1. In the present invention, when the cable body is towed, a number of lower rollers and a number of upper rollers are all in contact with and roll inside the pipeline. On the one hand, it avoids the cable body from being damaged by contact friction with the inner wall of the pipeline. On the other hand, through the rolling of a number of lower rollers and a number of upper rollers, the cable body is smoother during the towing process and is relatively less blocked, thereby reducing the difficulty of laying the cable body. At the same time, the shovel teeth can shovel up and break up the wet soil, sand and gravel at the bottom of the inner cavity of the pipeline, thereby destroying the coagulation state of the wet soil, sand and gravel and reducing the viscosity of the particles in the wet soil, sand and gravel. Cooperating with the rolling of a number of lower rollers and a number of upper rollers, it effectively reduces the resistance suffered by the cable during towing, thereby reducing the difficulty of laying the cable body;

[0030] 2. In the present invention, the shovel teeth can shovel up and collect larger sand and gravel particles, thereby reducing the amount of soil, sand and gravel in the pipeline, further reducing the resistance brought by the soil, sand and gravel when the cable is being towed, and reducing the amount of soil, sand and gravel can reduce the probability of the soil, sand and gravel wearing the cable body, thus effectively avoiding the wear of the cable body. At the same time, several groups of shovel teeth at the front end of the movement shovel up and collect larger sand and gravel particles in the pipeline, so that when the latter half of the cable body moves to this place, there is relatively less soil, sand and gravel here and less resistance, thereby reducing the difficulty of laying the cable body.

[0031] 3. In the present invention, when the collection cylinder moves, several shovel plates can shovel up the soil, sand and gravel inside the pipeline and make the shoveled soil, sand and gravel enter the collection cylinder, thereby further reducing the amount of soil, sand and gravel in the pipeline, and further reducing the resistance brought by the soil, sand and gravel when the cable is being towed. At the same time, reducing the amount of soil, sand and gravel can reduce the probability of the soil, sand and gravel wearing the cable body, thus effectively avoiding the wear of the cable body. Directly collecting the soil, sand and gravel, although it increases the gravity of the cable body when it is being towed, compared with directly pushing the soil, sand and gravel, this can greatly reduce the resistance generated by the soil, sand and gravel when the cable body is being towed, and cooperate with the rolling of several lower rollers and several upper rollers to further reduce the resistance suffered by the cable body when it is being towed, thereby reducing the difficulty of laying the cable body.

[0032] 4. In the present invention, during the process of the cable body being towed and moving, the movable sleeve one abuts against the collar two, and the movable sleeve two moves towards the limit sleeve, thereby bending the elastic piece, and further moving the cable body away from the bottom of the inner cavity of the pipeline, that is, away from the soil, sand and gravel in the pipeline. In this way, even if several groups of collection cylinders do not collect all the soil, sand and gravel, the remaining soil, sand and gravel are not easy to contact the cable body, thus effectively avoiding the wear of the cable body and further improving the protection effect on the cable body.

[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] The following describes in detail the specific implementation of the present invention in conjunction with specific embodiments.

[0042] As Figures 1 - 4 shown, a protection assembly for a wear-resistant cable includes:

[0043] A protective sleeve 2, which is fixedly sleeved on the periphery of the cable body 1, and a plurality of protective sleeves 2 are sleeved on the front end of the cable body 1 being towed;

[0044] A first fixing sleeve 21, which is arranged on the periphery of the protective sleeve 2. A plurality of lower rollers 24 and a plurality of upper rollers 25 are respectively installed above and below the first fixing sleeve 21, and the plurality of lower rollers 24 and the plurality of upper rollers 25 are all in contact with the inside of the pipeline;

[0045] A shoveling tooth 6, which is arranged at the bottom of one side of the first fixing sleeve 21 facing the moving direction of the cable body 1. A plurality of hollow parts are provided on the shoveling tooth 6, and the shoveling tooth 6 is in contact with the bottom of the pipeline inner cavity.

[0046] A stopping strip 61 is arranged on the shoveling tooth 6.

[0047] In a case of this embodiment, the size of the hollow parts on the shoveling tooth 6 is smaller than the size of most of the sand and gravel in the pipeline.

[0048] In actual application of this embodiment, when the cable body 1 is towed, the plurality of lower rollers 24 and the plurality of upper rollers 25 are all in contact with and roll on the inner wall of the pipeline. On the one hand, it avoids the cable body 1 from being damaged by contact friction with the inner wall of the pipeline. On the other hand, through the rolling of the plurality of lower rollers 24 and the plurality of upper rollers 25, the cable body 1 is smoother during the towing process and is relatively less blocked, thereby reducing the difficulty of laying the cable body 1;

[0049] A number of protective sleeves 2 are installed at the front end of the cable body 1 being towed, and the number of protective sleeves 2 keeps the cable body 1 from contacting the inner wall of the pipeline. Compared with the prior art of installing a sealing component on the whole cable body 1 for protection, the operation of the present invention is relatively easy, thus improving the cable laying efficiency;

[0050] During the towing process of the cable body 1, the shovel teeth 6 can shovel up and break up the wet soil, sand and gravel at the bottom of the inner cavity of the pipeline, thereby destroying the coagulation state of the wet soil, sand and gravel and reducing the viscosity of the particles in the wet soil, sand and gravel. Cooperating with the rolling of a number of lower rollers 24 and a number of upper rollers 25, the resistance suffered by the cable during towing is effectively reduced, thereby reducing the difficulty of laying the cable body 1;

[0051] In addition, the shovel teeth 6 can shovel up larger sand and gravel particles, which are blocked by the blocking strip 61, so that the larger sand and gravel particles are no longer in the pipeline, thereby reducing the amount of soil, sand and gravel in the pipeline, further reducing the resistance brought by the soil, sand and gravel to the cable during towing, and reducing the amount of soil, sand and gravel can reduce the probability of the soil, sand and gravel wearing the cable body 1, thereby effectively avoiding the wear of the cable body 1; At the same time, several groups of shovel teeth 6 at the moving front end shovel up and collect the larger sand and gravel particles in the pipeline, so that when the latter half of the cable body 1 moves to this place, the soil, sand and gravel here are relatively less and less blocked, thereby reducing the difficulty of laying the cable body 1; In addition, when the cable body 1 is laid, a part of the soil, sand and gravel in the pipeline is cleaned up, so that the cable body 1 laid subsequently is less blocked, further reducing the difficulty of laying the cable body 1.

[0052] Furthermore, a second fixing sleeve 22 is arranged on the periphery of the protective sleeve 2, a collecting cylinder 5 is sleeved on the periphery of the protective sleeve 2, one end of the collecting cylinder 5 is fixed on one side of the second fixing sleeve 22, the collecting cylinder 5 is located between the first fixing sleeve 21 and the second fixing sleeve 22, and a number of shovel plates 53 are installed at the bottom of the collecting cylinder 5 close to the first fixing sleeve 21.

[0053] In actual application of this embodiment, the protective sleeve 2 drives the collecting cylinder 5 to move. When the collecting cylinder 5 moves, a number of shovel plates 53 can shovel up the soil, sand and gravel inside the pipeline and make the shoveled soil, sand and gravel enter the collecting cylinder 5, thereby further reducing the amount of soil, sand and gravel in the pipeline, and further reducing the resistance brought by the soil, sand and gravel to the cable during towing; At the same time, reducing the amount of soil, sand and gravel can reduce the probability of the soil, sand and gravel wearing the cable body 1, thereby effectively avoiding the wear of the cable body 1;

[0054] Collect the soil, sand and gravel directly. Although it increases the gravity of the cable body 1 when it is being towed, compared with directly pushing the soil, sand and gravel, this can greatly reduce the resistance generated by the soil, sand and gravel to the cable body 1 when it is being towed. Moreover, with the rolling of a number of lower rollers 24 and a number of upper rollers 25, the resistance suffered by the cable body 1 when it is being towed is further reduced, thus reducing the difficulty of laying the cable body 1.

[0055] Further, two limiting rings 23 are arranged on the periphery of the protective sleeve 2. A rotating cylinder 3 is movably sleeved on the periphery of the protective sleeve 2. The rotating cylinder 3 is located between the two limiting rings 23. A toothed ring 31 is arranged on the periphery of the rotating cylinder 3. The toothed ring 31 is close to the first fixed sleeve 21. A driving assembly 4 is installed on the protective sleeve 2. The driving assembly 4 makes the rotating cylinder 3 rotate by driving the toothed ring 31. A spiral plate 32 is arranged on the periphery of the rotating cylinder 3. The spiral plate 32 is located in the collecting cylinder 5.

[0056] In one case of this embodiment, a baffle 52 is arranged on one side of the collecting cylinder 5 close to the first fixed sleeve 21. The baffle 52 can block the soil, sand and gravel located in the collecting cylinder 5, so as to ensure that the soil, sand and gravel in the collecting cylinder 5 are not easily leaked out.

[0057] When this embodiment is actually applied, the driving assembly 4 makes the driving toothed ring 31 drive the rotating cylinder 3 to rotate, so that the spiral plate 32 rotates. In this way, the soil, sand and gravel entering the collecting cylinder 5 can be conveyed to the innermost end of the collecting cylinder 5, so that the collecting cylinder 5 can slowly reach the full state. When the subsequent moving part of the cable body 1 moves to this place, the amount of soil, sand and gravel here is relatively small, thus reducing the resistance suffered by the cable when it is towed. At the same time, reducing the amount of soil, sand and gravel can reduce the probability of the soil, sand and gravel wearing the cable body 1, thus effectively avoiding the wear of the cable body 1.

[0058] Further, the driving assembly 4 includes:

[0059] A telescopic plate 41, which is fixedly installed on the surface of the protective sleeve 2;

[0060] A rotating rod 42, which is rotatably installed on the telescopic plate 41 and is parallel to the protective sleeve 2;

[0061] A main bevel gear 45 and a driven bevel gear 43. A main bevel gear 45 is installed on the rotating shaft of the upper roller 25. One end of the rotating rod 42 is installed with a driven bevel gear 43. The main bevel gear 45 and the driven bevel gear 43 are meshed with each other;

[0062] A gear 44, a gear 44 is fixed on the periphery of the rotating rod 42, and the gear 44 is meshed with the toothed ring 31.

[0063] In actual application of this embodiment, when the cable body 1 is towed and moved, a number of lower rollers 24 and a number of upper rollers 25 roll along the inner wall of the pipeline. When the upper rollers 25 roll, the main bevel gear 45 rotates. Through the rotation of the driven bevel gear 43, the rotating rod 42 drives the gear 44 to rotate, so that the toothed ring 31 drives the rotating cylinder 3 to rotate, and then the spiral plate 32 rotates to convey the soil, sand and gravel to the innermost end of the collection cylinder 5.

[0064] Further, a movable plate 51 is movably installed through the top of the collection cylinder 5. A number of telescopic members 54 are installed on the surface of the movable plate 51 and the surface of the collection cylinder 5. A connecting plate 46 is arranged on the surface of the movable plate 51. One side of the connecting plate 46 is rotatably connected to one end of the rotating rod 42.

[0065] In one case of this embodiment, the telescopic member 54 can be a spring or other components that can elastically expand and contract.

[0066] In actual application of this embodiment, when the collection cylinder 5 is slowly filled with soil, sand and gravel, the soil, sand and gravel will slowly push up the movable plate 51, so that the movable plate 51 moves upward. During the upward movement of the movable plate 51, the connecting plate 46 drives the rotating rod 42 to move upward, so that the gear 44 moves away from the toothed ring 31, and then the rotating cylinder 3 stops rotating, that is, it no longer conveys soil, sand and gravel into the collection cylinder 5, so that the collection cylinder 5 reaches a full state. Cooperating with the collection of several groups of collection cylinders 5 behind, it can collect soil, sand and gravel to the greatest extent, reduce the amount of soil, sand and gravel in the pipeline as much as possible, thereby reducing the resistance brought by the soil, sand and gravel when the cable is towed. At the same time, reducing the amount of soil, sand and gravel can reduce the probability of the soil, sand and gravel wearing the cable body 1, thus effectively avoiding the wear of the cable body 1;

[0067] When the collection cylinder 5 is full, the rotation of the rotating cylinder 3 is stopped, which effectively avoids the damage of the rotating cylinder 3 and the spiral plate 32 and ensures that the soil, sand and gravel in the collection cylinder 5 are not easily leaked.

[0068] Further, a shovel plate 53 is elastically rotatably installed on one side of the collection cylinder 5, and the shovel plate 53 always has a tendency to rotate towards the bottom of the pipeline lumen. A tightening strip 47 is arranged on the connecting plate 46. The tightening strip 47 is sleeved on the outside of a number of shovel plates 53, and the tightening strip 47 is attached to the outside of a number of shovel plates 53.

[0069] In one case of this embodiment, a torsion spring can be arranged on the elastically rotating part of the shovel plate 53.

[0070] In actual application of this embodiment, when the collection cylinder 5 is filled with soil, sand and gravel, the movable plate 51 moves upward, thereby causing the connecting plate 46 to move upward. When the connecting plate 46 moves upward, it will drive the tightening strip 47 to move upward, and the tightening strip 47 will drive a plurality of shovel plates 53 to turn upward, so that the shovel plates 53 no longer contact the inner wall of the pipeline. In this way, when the collection cylinder 5 is filled with soil, sand and gravel, the shovel plates 53 no longer shovel the soil, sand and gravel in the pipeline, thereby effectively reducing the resistance brought by the soil, sand and gravel to the shovel plates 53, and further reducing the resistance suffered by the cable body 1 during traction.

[0071] As Figures 1 - 5 shown, a wear-resistant cable includes the above-mentioned protection component of a wear-resistant cable. The wear-resistant cable further includes a cable body 1 and wear-resistant parts 7. A plurality of groups of wear-resistant parts 7 are installed at the rear end of the cable body 1 to be towed.

[0072] Furthermore, the wear-resistant parts 7 include:

[0073] a sleeve 71, which is fixedly sleeved on the periphery of the cable body 1;

[0074] a first collar 72 and a second collar 73, with the first collar 72 and the second collar 73 respectively arranged at both ends of the sleeve 71;

[0075] a limit sleeve 74, which is arranged on the periphery of the sleeve 71 and is located between the first collar 72 and the second collar 73;

[0076] a first movable sleeve 75 and a second movable sleeve 76, both of which are movably sleeved on the periphery of the sleeve 71. The first movable sleeve 75 is located between the second collar 73 and the limit sleeve 74, and the second movable sleeve 76 is located between the first collar 72 and the limit sleeve 74;

[0077] elastic pieces 77, with a plurality of elastic pieces 77 arranged between the first movable sleeve 75 and the second movable sleeve 76, and the elastic pieces 77 are in contact with the inner wall of the pipeline.

[0078] In actual application of this embodiment, during the process of the cable body 1 being towed and moving, the first movable sleeve 75 abuts against the second collar 73, and the second movable sleeve 76 moves towards the limit sleeve 74, thereby causing the elastic pieces 77 to bend, and further causing the cable body 1 to be away from the bottom of the pipeline lumen, that is, away from the soil, sand and gravel in the pipeline. In this way, even if several groups of collection cylinders 5 do not collect all the soil, sand and gravel, the remaining soil, sand and gravel are not easily in contact with the cable body 1, thereby effectively avoiding the wear of the cable body 1, and further improving the protection effect on the cable body 1.

[0079] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
