Description

Technical Field

[0001] The invention belongs to the technical field of cables, and in particular relates to a wear-resistant cable and a protective component thereof. Background Art

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

[0003] When laying the cable through pipes, since both ends of the pipe are exposed when laying the cable, after the cable is pulled into the pipe, the cable may bring dirt and gravel from the outside into the pipe, resulting in dirt and gravel in the pipe. In this way, when the cable is pulled, the surface of the cable is easily worn by dirt and gravel.

[0004] In response to the above-mentioned technical problems, the applicant has retrieved some prior arts, such as patent publication number CN117116541B, whose main technical means is to cooperate with each other through the arrangement of wear-resistant strips, wear-resistant rings and wear-resistant sliders, and before laying the cable into the underground pipeline, the wear-resistant ring is sleeved on the surface, and the wear-resistant slider slides with the underground pipeline. In the early stage of laying, the wear-resistant slider slides with the underground pipeline to replace the direct friction between the cable and the pipeline, during which the sealing tube assembly block is driven to fit the cable surface to drive away the sand and gravel, and in the later stage of laying, a plurality of wear-resistant rings are combined into a whole to form a complete sealing assembly, which can scrape the incoming cable surface to block the sand and gravel, so that the cable in the underground pipeline slides directly with the wear-resistant ring. The cable is not in motion and does not come into contact with sand and gravel, thus avoiding sand and gravel from rubbing against the outer surface of the cable, thereby achieving the effect of protecting the outer surface of the cable. After analysis by the applicant, the disadvantage of this technical solution is that when laying the cable, it is necessary to set multiple wear-resistant rings on the periphery of the cable to combine into a whole to form a complete sealing component. This is not only cumbersome to operate, but also the inside of the pipeline is in a humid state. When the cable is pulled, this sealing component comes into contact with moist soil and gravel. Since the moist soil and gravel contain moisture, viscosity will be generated between the particles, forming a condensed state. These condensed particles are not easy to be separated, resulting in the cable needing to overcome greater adhesion force, which will increase the traction resistance of the cable, resulting in greater obstruction of the cable when being pulled, thereby 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 protective component, aiming to solve the technical problem in the prior art that the sealing component contacts with wet soil and gravel, resulting in greater obstruction of the cable when being pulled, thereby increasing the difficulty of cable laying.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. In the present invention, when the cable body is pulled, the plurality of lower rollers and the plurality of upper rollers are in contact with the inside of the pipe and roll, which, on the one hand, avoids the cable body from being damaged by contact and friction with the inner wall of the pipe, and on the other hand, through the rolling of the plurality of lower rollers and the plurality of upper rollers, the cable body is smoother in the process of being pulled, and the obstruction is relatively small, 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 pipe, thereby destroying the condensation state of the wet soil, sand and gravel, and reducing the viscosity of the particles in the wet soil, sand and gravel. With the rolling of the plurality of lower rollers and the plurality of upper rollers, the resistance of the cable when being pulled is effectively reduced, thereby reducing the difficulty of laying the cable body;

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

[0031] 3. In the present invention, when the collecting tube moves, a plurality of shovel plates can shovel up the dirt and gravel inside the pipe, and make the shoveled dirt and gravel enter the collecting tube, thereby further reducing the amount of dirt and gravel in the pipe, and further reducing the resistance brought by the dirt and gravel to the cable when it is pulled; at the same time, reducing the amount of dirt and gravel can reduce the probability of the dirt and gravel wearing the cable body, thereby effectively avoiding the wear of the cable body; directly collecting the dirt and gravel, although increasing the gravity of the cable body when it is pulled, compared with directly pushing the dirt and gravel, this can greatly reduce the resistance generated by the dirt and gravel to the cable body when it is pulled, and cooperate with the rolling of a plurality of lower rollers and a plurality of upper rollers to further reduce the resistance of the cable body when it is pulled, thereby reducing the difficulty of laying the cable body;

[0032] 4. In the present invention, during the process of the cable body being pulled and moved, the movable sleeve 1 abuts against the ring 2, and the movable sleeve 2 moves toward the limiting sleeve, thereby bending the spring sheet, and thus making the cable body away from the bottom of the inner cavity of the pipeline, that is, away from the soil and gravel in the pipeline.

[0040] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is 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 intended to limit the present invention.

[0041] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0042] like Figure 1-Figure 4 As shown, a protective assembly for a wear-resistant cable comprises:

[0043] A protective cover 2, the protective cover 2 is fixedly covered on the outer periphery of the cable body 1, and a plurality of protective covers 2 are covered on the front end of the cable body 1 to be pulled;

[0044] A fixing sleeve 21 is disposed on the periphery of the protective sleeve 2, and a plurality of lower rollers 24 and a plurality of upper rollers 25 are respectively installed on the upper and lower parts of the fixing sleeve 21, and the plurality of lower rollers 24 and the plurality of upper rollers 25 are in contact with the inside of the pipeline;

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

[0046] A blocking bar 61 is provided on the shovel tooth 6 .

[0047] In one case of this embodiment, the size of the hollow portion on the shovel teeth 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 pulled, the plurality of lower rollers 24 and the plurality of upper rollers 25 are in contact with and roll against the inner wall of the pipe, which, on the one hand, prevents the cable body 1 from being damaged by contact and friction with the inner wall of the pipe, and, on the other hand, through the rolling of the plurality of lower rollers 24 and the plurality of upper rollers 25, makes the cable body 1 smoother in the process of being pulled, with relatively less obstruction, thereby reducing the difficulty of laying the cable body 1;

[0049] A plurality of protective covers 2 are installed at intervals at the front end of the cable body 1 to be pulled. The protective covers 2 prevent the cable body 1 from contacting the inner wall of the pipe. Compared with the prior art in which the sealing assembly is installed as a whole on the cable body 1 for protection, the present invention is relatively easy to operate, thereby improving the cable laying efficiency.

[0050] When the cable body 1 is being pulled, the shovel teeth 6 can shovel up and break up the wet soil and gravel at the bottom of the inner cavity of the pipe, thereby destroying the coagulation state of the wet soil and gravel and reducing the viscosity of the particles in the wet soil and gravel. In combination with the rolling of the lower rollers 24 and the upper rollers 25, the resistance of the cable when being pulled is effectively reduced, thereby reducing the difficulty of laying the cable body 1.

[0051] In addition, the shovel teeth 6 can scoop up larger sand and gravel particles and block them with the blocking bar 61, so that the larger sand and gravel particles are no longer in the pipeline, thereby reducing the amount of soil and gravel in the pipeline, and further reducing the resistance brought by the soil and gravel to the cable when it is pulled, and reducing the amount of soil and gravel can reduce the probability of soil 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 located at the front end of the movement scoop up and collect the larger sand and gravel particles in the pipeline, so that when the second half of the movement of the cable body 1 moves to this place, there is relatively less soil and gravel here, and the obstruction is less, thereby reducing the difficulty of laying the cable body 1; in addition, when the cable body 1 is laid, part of the soil and gravel in the pipeline is cleaned up, so that the subsequent laying of the cable body 1 is less obstructed, further reducing the difficulty of laying the cable body 1.

[0052] Furthermore, a fixed sleeve 22 is arranged on the periphery of the protective sleeve 2, and a collecting cylinder 5 is arranged on the periphery of the protective sleeve 2. One end of the collecting cylinder 5 is fixed on one side of the fixed sleeve 22. The collecting cylinder 5 is located between the fixed sleeve 1 21 and the fixed sleeve 22. A plurality of shovel plates 53 are installed on the bottom of the collecting cylinder 5 close to the fixed sleeve 1 21.

[0053] In actual application of this embodiment, the protective cover 2 drives the collecting tube 5 to move. When the collecting tube 5 moves, the plurality of shovel plates 53 can shovel up the dirt and gravel inside the pipe, and make the shoveled dirt and gravel enter the collecting tube 5, thereby further reducing the amount of dirt and gravel in the pipe, and further reducing the resistance brought by the dirt and gravel to the cable when it is pulled; at the same time, reducing the amount of dirt and gravel can reduce the probability of the dirt and gravel wearing the cable body 1, thereby effectively avoiding the wear of the cable body 1;

[0054] Although directly collecting the dirt and gravel increases the gravity of the cable body 1 when being pulled, compared with directly pushing the dirt and gravel, this can greatly reduce the resistance generated by the dirt and gravel to the cable body 1 when being pulled. In addition, the rolling of the lower rollers 24 and the upper rollers 25 can further reduce the resistance encountered by the cable body 1 when being pulled, thereby reducing the difficulty of laying the cable body 1.

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

[0056] In one case of this embodiment, a baffle 52 is provided on one side of the collecting tube 5 close to the fixing sleeve 21, and the baffle 52 can block the soil and gravel in the collecting tube 5, thereby ensuring that the soil and gravel in the collecting tube 5 are not easy to leak out.

[0057] In actual application of this embodiment, the driving gear ring 31 is driven by the driving component 4 to drive the rotating drum 3 to rotate, thereby rotating the spiral plate 32, so that the soil and gravel entering the collecting barrel 5 can be transported to the innermost end of the collecting barrel 5, so that the collecting barrel 5 can slowly reach a full state, so that when the moving part behind the cable body 1 moves to this place, the amount of soil and gravel here is relatively small, thereby reducing the resistance encountered by the cable when it is pulled. At the same time, reducing the amount of soil and gravel can reduce the probability of soil and gravel wearing the cable body 1, thereby effectively avoiding wear of the cable body 1.

[0058] Furthermore, the driving assembly 4 comprises:

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

[0060] A rotating rod 42, the rotating rod 42 is rotatably mounted on the telescopic plate 41, and the rotating rod 42 is kept parallel to the protective cover 2;

[0061] A main bevel gear 45 and a secondary bevel gear 43, the main bevel gear 45 is mounted on the rotating shaft of the upper roller 25, and the secondary bevel gear 43 is mounted on one end of the rotating rod 42, and the main bevel gear 45 and the secondary bevel gear 43 are meshed with each other;

[0062] Gear 44: A gear 44 is fixed to the periphery of the rotating rod 42, and the gear 44 is meshed with the gear ring 31.

[0063] In actual application of this embodiment, when the cable body 1 is pulled and moved, a plurality of lower rollers 24 and a plurality of upper rollers 25 roll along the inner wall of the pipe. When the upper rollers 25 roll, the main bevel gear 45 rotates, and the rotation of the slave bevel gear 43 drives the gear 44 to rotate, thereby causing the gear ring 31 to drive the rotating drum 3 to rotate, and then causing the spiral plate 32 to rotate to transport soil and gravel to the innermost end of the collecting drum 5.

[0064] Furthermore, a movable plate 51 is movably installed on the top of the collecting tube 5, and a plurality of telescopic parts 54 are installed on the surface of the movable plate 51 and the surface of the collecting tube 5. A connecting plate 46 is provided on the surface of the movable plate 51, and 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 may be a spring, or other elastically telescopic member.

[0066] In actual application of this embodiment, when the collecting barrel 5 is slowly filled with soil and gravel, the soil and gravel will slowly push the movable plate 51 upward, so that the movable plate 51 moves upward. In the process of the movable plate 51 moving upward, the connecting plate 46 drives the rotating rod 42 to move upward, so that the gear 44 is away from the gear ring 31, and then the rotating barrel 3 stops rotating, that is, the soil and gravel are no longer transported into the collecting barrel 5, so that the collecting barrel 5 reaches a full state, and the collection of the following groups of collecting barrels 5 can collect soil and gravel to the greatest extent, and reduce the amount of soil and gravel in the pipeline as much as possible, thereby reducing the resistance brought by soil and gravel to the cable when it is pulled. At the same time, reducing the amount of soil and gravel can reduce the probability of soil and gravel wearing the cable body 1, thereby effectively avoiding the wear of the cable body 1;

[0067] When the collecting barrel 5 is full, the rotation of the drum 3 is stopped, which effectively avoids damage to the drum 3 and the spiral plate 32 and ensures that the soil and gravel in the collecting barrel 5 are not easy to leak out.

[0068] Furthermore, the shovel plate 53 is elastically rotatably installed on one side of the collecting tube 5, and the shovel plate 53 always has a tendency to rotate toward the bottom of the inner cavity of the pipeline. A tightening strip 47 is provided on the connecting plate 46, and the tightening strip 47 is sleeved on the outer side of several shovel plates 53, and the tightening strip 47 is in contact with the outer side of several shovel plates 53.

[0069] In one aspect of this embodiment, the elastic rotating portion of the shovel plate 53 may be provided with a torsion spring.

[0070] In actual application of this embodiment, when the collecting tube 5 is full of soil and gravel, the movable plate 51 moves upward, thereby moving the connecting plate 46 upward. The upward movement of the connecting plate 46 will drive the tightening strip 47 to move upward, and the tightening strip 47 will drive a number of shovel plates 53 to flip upward, so that the shovel plates 53 no longer contact the inner wall of the pipe. In this way, when the collecting tube 5 is full of soil and gravel, the shovel plates 53 no longer shovel the soil and gravel in the pipe, thereby effectively reducing the resistance of the soil and gravel to the shovel plates 53, and further reducing the resistance encountered by the cable body 1 when being pulled.

[0071] like Figure 1-Figure 5 As shown, a wear-resistant cable includes the above-mentioned protective component of the wear-resistant cable. The wear-resistant cable also includes a cable body 1 and wear-resistant parts 7. The rear end of the cable body 1 to be pulled is equipped with several groups of wear-resistant parts 7.

[0072] Further, the wear-resistant part 7 comprises:

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

[0074] The first collar 72 and the second collar 73 are respectively provided at both ends of the sleeve 71;

[0075] A limiting sleeve 74 is disposed on the outer periphery of the sleeve 71 and is located between the first sleeve ring 72 and the second sleeve ring 73;

[0076] The movable sleeve 1 75 and the movable sleeve 2 76 are both movably sleeved on the outer periphery of the sleeve 71, the movable sleeve 1 75 is located between the sleeve ring 2 73 and the limiting sleeve 74, and the movable sleeve 2 76 is located between the sleeve ring 1 72 and the limiting sleeve 74;

[0077] Spring pieces 77, a plurality of spring pieces 77 are arranged between the movable sleeve 1 75 and the movable sleeve 2 76, and the spring pieces 77 are in contact with the inner wall of the pipe.

[0078] In actual application of this embodiment, when the cable body 1 is pulled and moved, the movable sleeve 1 75 abuts against the ring 2 73, and the movable sleeve 2 76 moves toward the limiting sleeve 74, so that the spring piece 77 bends, and the cable body 1 is moved away from the bottom of the pipeline cavity, that is, away from the soil and gravel in the pipeline. In this way, even if several groups of collecting tubes 5 do not collect all the soil and gravel, the remaining soil and gravel are not easy to contact the cable body 1, thereby effectively avoiding the wear of the cable body 1 and improving the protection effect of the cable body 1.

[0079] The above shows and describes 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 to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
