Description

Technical Field

[0001] The present invention relates to the technical field of communication engineering cable laying, and in particular to a device for laying communication engineering cables and a use method thereof. Background Art

[0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. According to the application scenario, it can be divided into several laying methods, such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. In addition, according to different laying scenarios, common laying methods of optical cables also include: laying in high-speed rail troughs, underwater laying, wall laying, leading up, indoor laying, etc. Reasonable selection of cable laying methods is very important to ensure the transmission quality, reliability and construction and maintenance of the line.

[0003] Laying optical cables along high-speed rail lines is not only easy to build and safe, but also can shorten the relay distance and reduce transmission delay. In recent years, the construction of trunk optical cables along high-speed rail lines has become more and more common. High-speed rail lines have their own power and communication needs. Strong and weak current troughs are set on both sides of the rails. At present, communication optical cables are usually laid in weak current troughs. Due to the limitation of the cross-sectional size of weak current troughs, optical cables are generally retained in the troughs by S-shaped laying. At present, mechanical means are usually used to release communication cables from cable drums, and then workers lay them out in an S shape, which reduces work efficiency.

[0004] For example, a communication cable laying device disclosed in Publication No. CN219420116U has the problem that the communication cable is released from the cable drum by machinery, and workers need to lay it in an S shape in the weak current slot. A communication engineering cable laying traction and delivery equipment disclosed in Publication No. CN217903858U also has the problem that the communication cable is released from the cable drum by machinery, and workers need to lay it in an S shape in the weak current slot.

The cable drum on which the communication cable is wound is installed on the mobile unit. The communication cable is then passed through the left conductor unit and the right conductor unit. The communication cable is clamped by the clamping plate.

The spring 261 provides the sliding rod 26 with elastic force toward the side where the cable drum 11 is located. A support rod 27 is fixedly installed at one end of the sliding rod 26, and two movable shafts 28 are movably installed on the inner wall below the support rod 27 through bearings. A support plate 29 is fixedly penetrated on the two movable shafts 28, and one half of the two support plates 29 is located on the left side of the movable shaft 28, and the other half is located on the right side of the movable shaft 28. An arc-shaped clamping plate 210 is fixedly installed at one end of the two support plates 29, and the inner side walls of the two arc-shaped clamping plates 210 are both in contact with the communication cable 12.

[0042] When in use, the cable drum 11 with the wound communication cable 12 is mounted on the mobile unit 1, and then the communication cable 12 is passed through the left conductor unit 13 and the right conductor unit 14, and the clamping plate 210 is controlled by the control panel to clamp the communication cable 12;

[0043] The servo motor 2 is started by controlling the control panel, the servo motor 2 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the gear 22 to rotate, the gear 22 drives the rack 23 to move, the rack 23 drives the connecting rod 25 to move, the guide rod 24 and the connecting rod 25 slide together, the connecting rod 25 drives the sliding rod 26 to move, the sliding rod 26 and the mobile unit 1 slide together, so that the rack 23 can drive the sliding rod 26 to move in a straight line, the sliding rod 26 drives the support rod 27 to move, the support rod 27 drives the support plate 29 to move through the movable shaft 28, the support plate 29 drives the clamping plate 210 to move, the clamping plate 210 pulls the communication cable 12 to move, so that the communication cable 12 is unwound from the cable drum 11, and the unwound communication cable 12 is laid into the weak current channel through the cooperation of the left wire unit 13 and the right wire unit 14;

[0044] When the connecting rod 25 drives the sliding rod 26 to move to the state closest to the side where the servo motor 2 is located, the control panel controls the clamping plate 210 to release the clamping of the communication cable 12, and at the same time controls the servo motor 2 to reverse, so that the servo motor 2 drives the support rod 27 and the clamping plate 210 to move to the side where the cable drum 11 is located through the gear 22 and the rack 23;

[0045] When the clamping plate 210 moves to the side closest to the cable reel 11, the control panel controls the clamping plate 210 to clamp the communication cable 12 again, and then the servo motor 2 drives the clamping plate 210 to move the communication cable 12 to the side away from the cable reel 11, thereby pulling the communication cable 12.

[0046] Embodiment 2: The technical solution of this embodiment is different from that of embodiment 1 in that: an auxiliary component for enhancing the clamping force is further provided in the support rod 27, and the auxiliary component includes: a limit rod 3, an inclined block 31, a second spring 32, an extrusion rod 33, a first forward contact 34, a second forward contact 35, a first reverse contact 36, a second reverse contact 37, an electromagnet 38, a magnet 39, a third spring 310 and a driving rod 311;

[0047] The limiting rod 3 is integrally slidably mounted in the support rod 27, an inclined block 31 is fixedly mounted on the side wall of the limiting rod 3, the bottom of the limiting rod 3 is located above the support plate 29 and between the two movable shafts 28, a spring 2 32 is fixedly mounted on the top of the limiting rod 3, the other end of the spring 2 32 is fixedly mounted in the support rod 27, and the spring 2 32 provides an elastic force for the limiting rod 3 to move away from the side where the movable shaft 28 is located;

[0048] An extrusion rod 33 is fixedly installed on the lower outer wall of the mobile unit 1, one end of the extrusion rod 33 is tilted and slidably matched with the inclined block 31, a forward contact 2 35 is fixedly installed on the side wall of the extrusion rod 33, a forward contact 1 34 matched with the forward contact 2 35 is fixedly installed on the side wall of the support rod 27, a reverse contact 1 36 is fixedly installed on the side wall of the support rod 27, and a reverse contact 2 37 matched with the reverse contact 1 36 is fixed on the side wall of the mobile unit 1, and the reverse contact 1 36 and the forward contact 1 34 are respectively located on two mutually parallel surfaces of the support rod 27;

[0049] An electromagnet 38 is fixedly installed on the side wall of the support rod 27, and two magnets 39 are arranged below the electromagnet 38. A driving rod 311 is fixedly installed at the bottom of the two magnets 39, and one end of the two driving rods 311 slides against the outer curved surface of the arc-shaped clamping plate 210, and a spring three 310 is fixedly installed at the bottom of the two magnets 39. The other ends of the two springs three 310 are respectively fixedly installed on the top of the two fixed plates, and one end of the two fixed plates is fixedly installed on the side wall of the support rod 27. One end of the two driving rods 311 is correspondingly slidably penetrated in the corresponding fixed plates, and the two magnets 39, the spring three 310, the fixed plate and the driving rod 311 are symmetrically distributed on both sides of the support rod 27.

[0050] When in use, when the support rod 27 moves toward the side where the cable drum 11 is located under the drive of the servo motor 2, the support rod 27 synchronously drives the reverse contact 1 36 to move;

[0051] When the support rod 27 is driven by the servo motor 2 to move to the side closest to the cable drum 11, the reverse contact 1 36 will abut against the reverse contact 2 37. At this time, the magnetic conversion of the electromagnet 38 makes the magnetism of the electromagnet 38 and the magnet 39 repel each other. The magnet 39 drives the driving rod 311 to move to the side away from the electromagnet 38 under the action of the repulsive force. The driving rod 311 and the fixed plate slide together, so that the driving rod 311 can only move up and down in a straight line under the drive of the magnet 39. The driving rod 311 squeezes the clamping plate 210, so that the clamping plate 210 drives the support plate 29 to flip around the movable shaft 28 as the axis. The driving rods 311 on both sides move downward synchronously, so that the clamping plates 210 on both sides are synchronously flipped inward to clamp the communication cable 12. At the same time, the servo motor 2 changes the rotation direction, so that the support rod 27 drives the clamping plate 210 to move to the side away from the cable drum 11.

[0052] When the support rod 27 moves away from the side where the cable drum 11 is located under the drive of the servo motor 2, the support rod 27 drives the reverse contact 1 36 to separate from the reverse contact 2 37, and the support rod 27 simultaneously drives the forward contact 1 34 to move;

[0053] When the support rod 27 is driven by the servo motor 2 to move to the side farthest from the cable drum 11, the extrusion rod 33 will first slide against the inclined block 31, and provide a supporting force to the inclined block 31 through the limit rod 3. The limit rod 3 and the support rod 27 slide together, so that the inclined block 31 moves linearly downward under the squeezing of the extrusion rod 33.

[0054] When the inclined block 31 moves to the lowest point, the forward contact 1 34 slides and abuts against the forward contact 2 35. At this time, the magnetic conversion of the electromagnet 38 makes the magnetism of the electromagnet 38 and the magnet 39 become attracted to each other. Under the action of the magnetic attraction force, the magnet 39 drives the driving rod 311 to move to the side close to the electromagnet 38, so that the driving rod 311 no longer applies an extrusion force to the clamping plate 210. At the same time, the limit rod 3 applies downward pressure to the support plate 29, so that the support plate 29 drives the clamping plate 210 to flip outward with the movable shaft 28 as the axis, thereby loosening the clamping of the communication cable 12. At the same time, the servo motor 2 changes the rotation direction, so that the support rod 27 drives the clamping plate 210 to move to the side close to the cable drum 11, until the reverse contact 1 36 and the reverse contact 2 37 abut again and change the movement direction.

[0055] Embodiment 3, the technical solution of this embodiment is different from that of embodiment 2, including: a cycloid assembly for placing the communication cable 12 is provided on the mobile unit 1, and the cycloid assembly includes: a servo motor 2, a rotating shaft 21, a limit plate 4, a guide column 1 41, a fixed rod 1 42, a clamping plate 43, a guide column 2 44, a fixed rod 2 45, and a guide plate 46; the servo motor 2 provides power to the cycloid assembly through the rotating shaft 21, the limit plate 4 is fixedly sleeved on the rotating shaft 21 to limit the moving direction of the cycloid assembly, and a guide column 1 is slidably inserted in the limit plate 4 41 and a guide column 44, one end of the guide column 41 is fixedly installed on the top of a fixing rod 42, a semicircular card plate 43 is fixedly installed on the bottom of the fixing rod 42, one end of the fixing rod 42 is T-shaped and slidably penetrates into the mobile unit 1, one end of the guide column 44 is fixedly installed with a fixing rod 45, one end of the fixing rod 45 is fixedly installed with a guide plate 46, one end of the fixing rod 45 which is cross-shaped is slidably penetrated into the mobile unit 1, and one end of the communication cable 12 is slidably penetrated into the guide plate 46 and the card plate 43.

[0056] When in use, while the servo motor 2 drives the gear 22 to rotate through the rotating shaft 21, the rotating shaft 21 synchronously drives the limit plate 4 to rotate, and the limit plate 4 and the guide column 1 41 and the guide column 2 44 are all in sliding contact with each other, and the guide column 1 41 and the guide column 2 44 are in sliding cooperation with the mobile unit 1, so that when the limit plate 4 rotates, it can drive the guide column 1 41 and the guide column 2 44 to move linearly along the mobile unit 1;

[0057] The guide column 41 drives the fixing rod 42 to move, and the fixing rod 42 and the moving unit 1 slide together, so that the fixing rod 42 can drive the clamping plate 43 to move linearly under the drive of the guide column 41;

[0058] The second guide post 44 drives the second fixing rod 45 to move, and the second fixing rod 45 and the moving unit 1 slide together, so that the second fixing rod 45 can drive the guide plate 46 to move linearly under the drive of the second guide post 44;

[0059] At the same time, the moving directions of the guide column 1 41 and the guide column 2 44 are opposite, so that the moving directions of the clamping plate 43 and the guide plate 46 are opposite;

[0060] When the communication cable 12 is intermittently conveyed to the guide plate 46 and the clamping plate 43 with the cooperation of the wire feeding assembly and the left and right wire units 13 and 14, it can be laid in an S shape in the weak-wire trough under the limitation of the clamping plate 43 and the guide plate 46 moving in the opposite direction. A section of the communication cable 12 is intermittently pulled out from the cable reel 11 through the wire feeding assembly, so that the communication cable 12 located at the clamping plate 43 and the guide plate 46 is in a state without the action of external force, so that it can be more easily placed in an S shape during the movement of the clamping plate 43 and the guide plate 46.

[0061] In another embodiment, a cutting assembly can be integrated at the card plate 43, and the cutting assembly includes two sets of upper and lower cutting knives, wherein the upper cutting knife is fixedly mounted on the bottom of the mobile unit 1 through an electric push rod, and the lower cutting knife is fixedly mounted on the side wall of the mobile unit 1 through a support seat. The two cutting knives in the cutting assembly cooperate with each other to cut off the communication cable 12, so that the communication cable 12 is automatically cut off after about 500 meters of the communication cable 12 is laid in the low-voltage cable trough.

[0062] The embodiment of the present invention also provides a method for using a device for laying cables in communication engineering, comprising the following steps:
