[0029] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides a cable laying device, comprising:

[0030] Two moving components 1;

[0031] A cable pay-off component 2, which is installed on one of the moving components 1;

[0032] A traction component 3, which is installed on the other moving component;

[0033] A collar component 4, which is installed at one end of the cable pay-off component 2 close to the traction component 3, and the collar component 4 is used to sleeved a friction-proof ring 5 on the cable.

[0034] In the above embodiment, the cable laying device includes two moving components, a cable pay-off component, a traction component and a collar component. The moving component can be a trolley or an electric vehicle. An installation platform is provided on the moving component, and the two moving components are arranged oppositely. The cable pay-off component is installed on the installation platform of one of the moving components, and the cable pay-off component is used to mount a cable reel and push the cable outwards. The traction component is installed on the installation platform of the other moving component, and a traction seat for fixing the cable is provided on the traction component, and the free end of the cable is fixed on the traction seat. The collar component is installed at one end of the cable pay-off component close to the traction seat, and the collar component is used to sleeved a friction-proof ring on the cable.

[0035] During use, first mount the cable reel on one of the moving components, then move this moving component to a preset position in the cable trench, then fix the free end of the cable on the traction seat of the traction component, and then move the other moving component along the cable trench in a direction away from the cable pay-off component. During the movement, the cable reel automatically rotates to pay off the cable, the collar component automatically sleeved a friction-proof ring on the cable payed off by the cable pay-off component, and the traction component drags the cable sleeved with the friction-proof ring to move along the cable trench. Since the friction-proof ring is sleeved on the surface of the cable and protrudes from the cable surface, it is avoided that the cable surface directly contacts the bottom surface and / or side wall of the cable trench during the cable dragging process, effectively avoiding the abrasion of the cable surface during the cable laying process.

[0036] The present invention adds a collar component at one end of the cable pay-off component close to the traction component. During cable laying, the collar component can sleeved a friction-proof ring on the surface of the cable payed off by the cable pay-off component, and the friction-proof ring protrudes from the cable surface. During the cable dragging process, the friction-proof ring can replace the cable surface to contact the bottom surface and / or side wall of the cable trench, thereby avoiding the abrasion of the cable surface and achieving the effect of protecting the cable.

[0037] In another embodiment, as Figure 4As shown, for the cable laying device, the anti-friction ring 5 includes a first anti-friction ring 51 and a second anti-friction ring 52. Both the first anti-friction ring 51 and the second anti-friction ring 52 are semi-circular, and the first anti-friction ring 51 and the second anti-friction ring 52 are snap-fitted to form a ring. Here, the anti-friction ring is set to include semi-circular and snap-fitted first and second anti-friction rings to facilitate quickly sleeving the anti-friction ring on the cable.

[0038] In another embodiment, as Figure 2 、 Figure 3 shown, for the cable laying device, the collar assembly 4 includes a first collar assembly 41 and a second collar assembly 42 symmetrically arranged on both sides of the cable to be sleeved. The structures of the first collar assembly 41 and the second collar assembly 42 are the same and both include: a channel 43 which is vertically arranged, the top surface of the channel 43 is open, the bottom surface is closed, and an opening is provided on the bottom side wall of the channel 43 along the direction perpendicular to the cable to be sleeved; a first cylinder 44 which is arranged on the side of the channel 43 away from the cable to be sleeved, and a push block 45 is fixedly arranged at the output end of the first cylinder 44; wherein, the first anti-friction ring 51 is placed in the channel 43 of the first collar assembly 41, and the second anti-friction ring 52 is placed in the channel 43 of the second collar assembly 42. The axial directions of the first anti-friction ring 51 and the second anti-friction ring 52 located in the channel 43 are parallel to the cable to be sleeved and the openings face the cable to be sleeved, and the cross-section of the channel 43 only allows one of the first anti-friction ring 51 or the second anti-friction ring 52 to pass through; the push block 45 can be driven by the first cylinder 44 to extend into the opening and push the first anti-friction ring 51 or the second anti-friction ring 52 located at the bottom of the channel 43 towards the direction close to the cable to be sleeved, so that the first anti-friction ring 51 and the second anti-friction ring 52 are snap-fitted and sleeved on the cable to be sleeved.

[0039] In the above embodiments, by symmetrically arranging the first collar assembly and the second collar assembly on both sides of the cable to be sleeved, both the first collar assembly and the second collar assembly include vertically arranged channels. An opening is provided at the bottom of the channel. A first cylinder is provided on the side of the bottom of the channel away from the cable to be sleeved. A push block is fixedly provided at the output end of the first cylinder, and the push block is arranged opposite to the opening. In use, place the first anti-friction ring in the channel of the first collar assembly. The axis of the first anti-friction ring is parallel to the cable to be sleeved and the opening faces the cable to be sleeved. Place the second anti-friction ring in the channel of the second collar assembly. The axis of the second anti-friction ring is parallel to the cable to be sleeved and the opening faces the cable to be sleeved. Since the cross-section of the channel only allows one first anti-friction ring or second anti-friction ring to pass through, after the push blocks on the first collar assembly and the second collar assembly push the first anti-friction ring and the second anti-friction ring located at the bottom of the channel to be snap-fitted and reset, the first anti-friction ring and the second anti-friction ring in the channel can sequentially enter the bottom of the channel and be pushed and snap-fitted by the push blocks, thereby realizing automatically sleeving the first anti-friction ring and the second anti-friction ring on the surface of the cable.

[0040] Further, when the first anti-friction ring 51 and the second anti-friction ring 52 are snap-fitted, the side of the push block 45 away from the cable to be sleeved is located within the opening, so that before the push block resets, the first anti-friction ring and the second anti-friction ring above the push block do not fall, ensuring the stable operation of the collar assembly.

[0041] In another embodiment, as Figure 2 , Figure 3 shown, for the cable laying device, the first collar assembly 41 and the second collar assembly 42 further include: a material sorting tray 46, which is horizontally arranged above the side of the channel 43. A first magnet is provided along the circumference in the middle of the inner wall of the material sorting tray 46; a rotating plate 47, which is horizontally arranged at the inner bottom of the material sorting tray 46 and is in sliding contact with the inner wall of the material sorting tray 46. The rotating plate 47 is driven to rotate by a first motor 48 arranged above the material sorting tray; a stop bar 49, which is arranged along the radial direction of the material sorting tray 46. One end of the stop bar 49 is fixedly provided on the inner wall of the material sorting tray 46, and the other end is suspended. And the height of the stop bar 49 on the material sorting tray 46 is slightly higher than the axial length of the anti-friction ring 5, such as 1-2 cm higher; a connecting groove 410, one end of which is open and tangentially communicates with the side wall of the material sorting tray 46. The other end of the connecting groove 410 is closed, and the bottom surface of the other end communicates with the top surface of the channel 43; wherein, the axial length of the anti-friction ring 5 is less than the diameter of the anti-friction ring 5, and the longitudinal section of the connecting groove 410 only allows one first anti-friction ring 51 or one second anti-friction ring 52 to pass through; second magnets 56 are provided in the middle of the outer side walls of the first anti-friction ring 51 and the second anti-friction ring 52, and the second magnets 56 are magnetically attracted to the first magnets.

[0042] In the above embodiments, by arranging a sorting tray above the side of the channel, a rotating plate driven by a first motor is provided at the bottom of the sorting tray, a retaining rod and a first magnet are arranged on the inner side wall of the sorting tray, a second magnet is arranged on the outer walls of the first anti-friction ring and the second anti-friction ring, a connecting groove is arranged between the sorting tray and the channel, and one end of the connecting groove is open and tangentially communicated with the side wall of the sorting tray, and the other end is closed and communicated with the top of the channel through the bottom surface of the other end. During use, only the first anti-friction ring and the second anti-friction ring need to be placed in the corresponding sorting tray. Under the action of the rotating rotating plate, the first anti-friction ring and the second anti-friction ring move to the inner wall of the sorting tray, are adsorbed on the inner wall of the sorting tray by the first magnet and the second magnet, and move along the circumference of the sorting tray. During the movement, under the action of the retaining rod, the first anti-friction ring and the second anti-friction ring rotate automatically, so that the axial directions of the first anti-friction ring and the second anti-friction ring are in a vertical state. The rotated first anti-friction ring and second anti-friction ring continue to move and enter the connecting groove, and continue to move to the other end of the connecting groove under the action of the rotating rotating plate and their own gravity, and are automatically turned over under their own gravity and enter the channel. At this time, the axial directions of the first anti-friction ring and the second anti-friction ring are in a horizontal state, that is, the automatic feeding of the first anti-friction ring and the second anti-friction ring in the channel is realized.

[0043] Further, it is set that the first collar assembly 41 is located in front of the second collar assembly 42, and the rotating plate 47 on the first collar assembly 41 rotates counterclockwise under the drive of the first motor 48, and the rotating plate 47 on the second collar assembly 42 rotates clockwise under the drive of the first motor 48.

[0044] In another embodiment, such as Figure 1 、 Figure 2 and Figure 3As shown, for the cable laying device described above, the wire pay-off assembly 2 includes: a cable reel 21 mounted on one of the moving assemblies 1, the cable reel 21 being driven to rotate by a second motor provided on one side thereof, and the cable to be laid being wound around the cable reel 21; a mounting plate 22 horizontally provided above the moving assembly 1, the mounting plate 22 being driven to move up and down by a second cylinder 23 provided at its bottom; a first support frame 24 fixedly provided on the mounting plate 22 and parallel to the axial direction of the cable reel 21; a second support frame 25 provided on the side of the first support frame 24 away from the cable reel 21 and perpendicular to the axial direction of the cable reel 21, the height of the second support frame 25 being lower than the height of the first support frame 24; a support plate 26 horizontally provided at the top of one end of the second support frame 25 close to the first support frame 24 and perpendicular to the second support frame 25; a cable trough 27 including an inclined section, a telescopic section and a horizontal section that are sequentially connected. The high end of the inclined section is placed on the top of the first support frame 24 and is in sliding contact with the first support frame 24. The telescopic section is placed on the support plate 26, and the horizontal section is fixedly provided on the top of the second support frame 25. Among them, the channel 43 is provided on both sides of the outlet end of the horizontal section.

[0045] In the above implementation, the cable released from the cable reel is guided by the cable trough and then connected to the traction assembly, so that the wire outlet position at one end of the wire pay-off assembly close to the traction assembly is fixed. Further, by mounting the cable trough on the mounting plate and providing a second cylinder at the bottom of the mounting plate, the height of the cable trough can be adjusted by the second cylinder according to the height of the cable on the cable reel, so that the height of the cable trough is appropriate; by fixedly providing a first support frame, a support plate and a second support frame on the mounting plate, the height of the second support frame is lower than the height of the first support frame, and the inclined section of the cable trough is placed on the top of the first support frame, the telescopic section is placed on the support plate, and the horizontal section is fixedly provided on the second support frame, so that the cable trough can automatically adjust the position of the inclined section on the first support frame according to the wire outlet position of the cable on the cable reel, so as to avoid too large a bend angle between the cable and the cable trough and damage the cable.

[0046] Further, a telescopic column 28 is fixedly provided at each of the four corners of the mounting plate 22. One end of the telescopic column 28 is fixedly connected to the mounting plate 22 perpendicularly, and the other end is fixedly connected to one of the moving assemblies perpendicularly, so that the mounting plate is stably supported on one of the moving assemblies.

[0047] In another implementation, as Figure 2 、 Figure 3 and Figure 5As shown, for the cable laying device, the first support frame 24 includes a telescopic plate 241 and baffles 242 provided on both its front and rear sides. The telescopic plate 241 is parallel to the axial direction of the cable reel 21. The telescopic plate 241 includes an upper plate 243 and a lower plate 244. The upper plate 243 is sleeved inside the lower plate 244 and connected by a spring 245. The baffle 242 is provided on the side of the telescopic plate 241 away from the cable reel 21 and is perpendicular to the telescopic plate 241.

[0048] Further, the baffle 242 is fixedly connected to the side wall of the lower plate 244 and is in sliding contact with the side wall of the upper plate 243.

[0049] Here, by setting the first support plate to be composed of a telescopic plate and a baffle, the inclined section of the cable trough is placed on the telescopic plate. The telescopic plate can automatically fine-tune the height according to the force to further adapt to the height of the cable outgoing from the cable reel, avoiding too large an angle at the fold of the cable and the cable trough and damaging the cable.

[0050] In another embodiment, as Figure 4 shown, for the cable laying device, hook grooves are provided on both end faces of the first anti-friction ring 51. The hook grooves include a wedge-shaped part and a rectangular part formed integrally, and the rectangular part faces outward. Hooks 53 that cooperate with the hook grooves for snap connection are provided on both end faces of the second anti-friction ring 52. The hooks 53 include a wedge-shaped clamping block and a rectangular clamping block formed integrally, and the free end of the rectangular clamping block is fixedly connected to the end face of the second anti-friction ring 52.

[0051] Further, the radial length of the rectangular part along the anti-friction ring 5 is less than the maximum radial length of the wedge-shaped part along the anti-friction ring 5.

[0052] Here, by providing hook grooves and hooks on the first anti-friction ring and the second anti-friction ring that cooperate for snap connection, it is avoided that the first anti-friction ring and the second anti-friction ring come out after being snap-connected, realizing the stable connection of the first anti-friction ring and the second anti-friction ring.

[0053] In another embodiment, as Figure 4 shown, for the cable laying device, a plurality of ball grooves are provided at intervals on the outer side walls of the first anti-friction ring 51 and the second anti-friction ring 52. Each ball groove is embedded with a ball 54. Here, by embedding balls on the outer side walls of the first anti-friction ring and the second anti-friction ring, the balls are made to contact the bottom surface and / or side wall of the cable trench, changing the sliding friction to rolling friction, thereby reducing the wear of the anti-friction ring during the cable dragging process.

[0054] In another embodiment, as Figure 4As shown, in the cable laying device, elastic washers 55 are provided on the inner side walls of the first anti-friction ring 51 and the second anti-friction ring 52 to protect the cable and at the same time achieve a stable connection between the anti-friction ring and the cable.

[0055] In another embodiment, as Figure 1 shown, in the cable laying device, the moving component 1 is a trolley, and the wheels of the trolley are universal wheels with brakes, so as to facilitate the fixing of the position of the moving component.

[0056] Although the embodiments of the present invention have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made.
