Technical Field

[0001] This application belongs to the field of cable production technology, specifically relating to a cable laying device. Background Technology

[0002] In existing technologies, cable laying is a core foundational operation in the installation of power and communication systems. It requires the precise movement of cables to predetermined locations, and the quality and efficiency of this operation directly impact the construction progress and operational stability of the entire system. Cable laying auxiliary devices, as key equipment in this operation, can effectively replace manual handling, reduce labor intensity, and improve the standardization of cable laying, thus providing crucial support for ensuring the smooth progress of cable laying operations. However, current cable laying auxiliary devices on the market still have many shortcomings.

[0003] In existing technologies, traditional cable laying relies heavily on manual labor, which is not only extremely labor-intensive and inefficient, but also prone to cable wear and bending due to improper human operation, posing significant safety hazards and quality risks. Existing mechanized cable laying auxiliary devices are mostly only compatible with single-specification cables. When faced with the need to lay cables of different diameters and materials, specialized devices must be used, increasing preparation time, reducing overall efficiency, and raising equipment purchase and maintenance costs. Furthermore, these devices generally have a large footprint, making them difficult to deploy flexibly in confined spaces. Their unreasonable contact and compatibility design with the cable leads to low assembly stability, causing cable slippage and misalignment during laying, affecting laying accuracy.

[0004] Therefore, in order to comprehensively improve the specification adaptability, spatial adaptability and assembly stability of cable laying auxiliary devices, reduce operating costs and safety risks, it is now urgent to make improvements to meet diverse cable laying needs and improve operating efficiency and laying quality. Utility Model Content

Therefore, this application proposes a cable laying device.

[0026] Combination Figures 1 to 9 The following content further illustrates the technical solution proposed in this application. This application adopts the following technical solution: a cable laying device, comprising multiple limiting seats 1, a connecting assembly 2 disposed between two adjacent limiting seats 1, and a sliding assembly 3 disposed on the outside of the limiting seats 1. The multiple limiting seats 1 are rotatably connected end-to-end, and the multiple limiting seats 1 can collectively form an installation station 4. The cable to be laid is disposed within the installation station 4. The connecting assembly 2 includes a connecting groove 20 disposed on one side of the limiting seat 1, a connecting lug 21 disposed on the other side of the limiting seat 1, a first connecting hole 22 disposed on the connecting groove 20, a second connecting hole 23 disposed on the connecting lug 21 at a position corresponding to the first connecting hole 22, and a connecting pin 24 disposed within the first connecting hole 22 and the second connecting hole 23.

[0027] This application provides a cable laying device, comprising multiple limiting seats, a connecting assembly disposed between adjacent limiting seats, and a sliding assembly disposed outside the limiting seats. The multiple limiting seats are rotatably connected end to end to form an installation station. The cable to be laid is placed within the installation station. The connecting assembly achieves detachable connection of the limiting seats through the cooperation of connecting grooves, connecting ears, and connecting pins. By setting multiple rotatably connected limiting seats, this application allows for flexible adjustment of the installation station size to accommodate cables of different specifications, significantly improving work efficiency. The sliding assembly reduces frictional resistance during cable laying, replacing manual carrying and pulling, reducing labor intensity, and preventing cable wear and bending, eliminating safety hazards and quality risks. The compact modular structure occupies little space, and the stable cooperation of the connecting assembly enhances assembly stability and prevents cable slippage. Its structure is simple, easy to operate, low in implementation cost, highly adaptable, and easy to promote and implement.

[0028] In this embodiment, multiple connecting grooves 20 are spaced apart along the height direction of the limiting seat 1, and multiple connecting ears 21 are spaced apart along the height direction of the limiting seat 1.

[0029] In actual implementation, a corresponding number of limiting seats are selected based on the diameter of the cable to be laid. The connecting ears of adjacent limiting seats are inserted into the connecting grooves of adjacent limiting seats. After aligning the first and second connecting holes, the connecting pin is inserted. Through the cooperation of multiple sets of height-spaced connecting grooves and connecting ears, the limiting seats are securely connected, forming an installation station adapted to the cable specifications. The assembled cable laying auxiliary device is placed on the cable laying path. In confined spaces, the overall length can be adjusted by reducing the number of limiting seats, allowing for flexible deployment in complex working environments. When the cable is placed in the installation station and pulled, the sliding components on the outside of the limiting seats generate rolling friction with the ground / contact surface, significantly reducing the resistance to cable movement. At the same time, the enclosed installation station provides radial restraint for the cable, preventing slippage and deviation. The multiple rotating limiting seats can adaptively adjust their angles according to the cable's direction, ensuring smooth laying.

[0030] In this embodiment, the connecting pin 24 includes a connecting seat 240, a sliding groove 241 on the connecting seat 240, a pin 242 in the sliding groove 241, and a return spring 243 between the pin 242 and the bottom of the sliding groove 241. The pin 242 can slide along the height direction of the sliding groove 241.

[0031] In actual implementation, when installing adjacent limit seats, manually press the pin to compress the return spring, causing the pin to retract into the slide groove. After inserting the connecting lug into the connecting groove and aligning the first and second connecting holes, release the pin. The return spring releases its elastic potential energy, pushing the pin out along the slide groove and through the two connecting holes to achieve quick locking of the limit seats. During disassembly, press the pin again to disengage it from the connecting hole and retract it into the slide groove, thus releasing the fixed relationship between the limit seats and quickly separating the components. During cable laying, when the cable laying auxiliary device vibrates due to cable pulling or is impacted by external forces, the return spring always applies a tightening force to the pin, ensuring that the pin is stably engaged in the connecting hole and preventing loosening of the connection.

[0032] In this embodiment, the sliding component 3 includes a plurality of sliding seats 30 spaced apart along the length direction of the limiting seat 1, ball grooves 31 provided on the sliding seats 30, and balls 32 matched and provided in the ball grooves 31.

[0033] In this embodiment, the material of the ball bearing 32 is selected from any one of polyoxymethylene resin (POM), polybutylene terephthalate resin (PBT), polyethylene terephthalate resin (PET), nylon, and polyphenylene sulfide (PPS).

[0034] In actual implementation, the ball bearing 32 is made of polyoxymethylene resin (POM).

[0035] During actual assembly, the ball bearings are embedded into the ball bearing grooves of the sliding seats. The ball bearing grooves limit the movement of the ball bearings, ensuring they can only roll within the grooves and do not fall out. Multiple sliding seats are installed at intervals along the length of the limiting seats, ensuring even force distribution. After the cable laying auxiliary device is deployed, the sliding components are in direct contact with the ground / working surface. When pulling the cable, the cable drives the limiting seats to move, and the ball bearings generate rolling friction with the contact surface, significantly reducing movement resistance compared to traditional sliding friction. Simultaneously, the spaced-out sliding seats can adapt to uneven ground, achieving smooth device movement through the independent rolling of individual ball bearings, avoiding jamming.

[0036] In this embodiment, a positioning component 5 is also provided between the sliding component 3 and the limiting seat 1. The positioning component 5 is used to position the sliding component 3 on the limiting seat 1. The positioning component 5 includes a first positioning groove 50 provided on the limiting seat 1, a second positioning groove 51 provided on both sides of the first positioning groove 50, and positioning ribs 52 provided on both sides of the sliding seat 30 at corresponding positions of the second positioning grooves 51. When the sliding seat 30 is inserted into the first positioning groove 50, the positioning ribs 52 are inserted into the second positioning grooves 51.

[0037] In this embodiment, the positioning component 5 further includes a positioning post 53 disposed at the bottom of the first positioning groove 50, and a third positioning groove 54 disposed at the bottom of the sliding seat 30 at the position corresponding to the positioning post 53. When the sliding seat 30 is inserted into the first positioning groove 50, the positioning post 53 is inserted into the third positioning groove 54.

[0038] In actual implementation, when assembling the sliding assembly, first align the sliding seat with the first positioning groove on the limiting seat, aligning the positioning ribs on both sides of the sliding seat with the second positioning grooves on both sides of the first positioning groove. Through the guiding cooperation of the ribs and grooves, the initial positioning of the sliding seat is quickly completed, preventing installation misalignment. Push the sliding seat fully into the first positioning groove; at this point, the positioning post at the bottom of the first positioning groove will precisely embed into the third positioning groove at the bottom of the sliding seat. During cable laying, the lateral and longitudinal forces generated by the ground friction and cable traction of the sliding assembly are counteracted by the lateral limiting of the positioning ribs and the second positioning groove, and the vertical limiting of the positioning post and the third positioning groove, ensuring a stable connection between the sliding seat and the limiting seat, preventing relative displacement.

[0039] In this embodiment, an anti-slip layer 6 is also provided inside the installation station 4. When the cable to be laid out is placed inside the installation station 4, the anti-slip layer 6 covers the outer periphery of the cable to be laid out.

[0040] In this embodiment, the anti-slip layer 6 is made of any one of ethylene-vinyl acetate copolymer, styrene-butadiene rubber, nitrile rubber, or chloroprene rubber.

[0041] In actual implementation, the anti-slip layer 6 is made of ethylene-vinyl acetate copolymer.

[0042] In actual implementation, the anti-slip layer is pre-fixed inside the installation station. The flexible polymer material used in its construction possesses a certain degree of elasticity, allowing it to adapt and deform according to the dimensions of the installation station. After the cable to be laid is placed in the installation station, the anti-slip layer, under the pressure of the cable, generates elastic recovery force, tightly wrapping around the cable's outer circumference to form a fully fitted contact. When the cable is pulled, the high coefficient of friction of the anti-slip layer material increases the friction with the cable surface, counteracting the cable's axial and radial displacement along the installation station. Simultaneously, the elastic material absorbs vibrations during the laying process, preventing slippage caused by hard contact between the cable and the limiting seat, ensuring the cable is stably laid along the preset path.

[0043] This application provides a cable laying device, comprising multiple limiting seats, a connecting assembly disposed between adjacent limiting seats, and a sliding assembly disposed outside the limiting seats. The multiple limiting seats are rotatably connected end to end to form an installation station. The cable to be laid is placed within the installation station. The connecting assembly achieves detachable connection of the limiting seats through the cooperation of connecting grooves, connecting ears, and connecting pins. By setting multiple rotatably connected limiting seats, this application allows for flexible adjustment of the installation station size to accommodate cables of different specifications, significantly improving work efficiency. The sliding assembly reduces frictional resistance during cable laying, replacing manual carrying and pulling, reducing labor intensity, and preventing cable wear and bending, eliminating safety hazards and quality risks. The compact modular structure occupies little space, and the stable cooperation of the connecting assembly enhances assembly stability and prevents cable slippage. Its structure is simple, easy to operate, low in implementation cost, highly adaptable, and easy to promote and implement.
