Description

Technical Field

[0001] The utility model belongs to the technical field of cable laying, and in particular relates to a telescopic cable laying device with adaptive guidance. Background Art

[0002] With the rapid development of the domestic new energy industry, the construction of new booster stations and energy storage power stations is being promoted to meet the needs of renewable energy access to the grid and improve the quality and stability of power supply. The construction and operation of these power facilities are inseparable from a large amount of cable construction work. Cable laying is a key link in connecting various electrical equipment and realizing energy transmission. However, in current construction practices, cable laying still faces many challenges.

[0003] Traditional cable threading methods usually require a lot of manual work, which is not only labor-intensive but also inefficient. Especially at construction sites, the pipes that cables need to pass through often present a variety of curved shapes or have different diameters, which makes it very easy for cables to get stuck or damaged during the laying process. This situation is particularly obvious when passing through pipes of multiple materials or inconsistent diameters, which increases the difficulty of construction and may affect the safe operation of the entire power system.

[0004] In addition, the friction force on the cable during the pipe threading process can cause the outer skin to wear and even damage the internal conductor, which not only reduces the service life of the cable, but may also cause safety accidents such as electrical short circuits due to local damage to the cable. Therefore, reducing physical damage during cable laying and improving pipe threading efficiency have become technical issues that need to be urgently solved in this field.

[0005] In order to improve the safety, reliability and work efficiency of cable laying, it is urgent to develop a new type of cable pipe threading process or equipment to adapt to the development needs of the new energy industry, reduce labor input, reduce the risk of damage in cable construction, and improve construction efficiency.

[0007] The telescopic cable laying device with adaptive guidance comprises: a cylinder 1, which is axially through-through, and a convex ring 9 is provided at the front end of the cylinder 1, the outer diameter of the convex ring 9 gradually decreases from the back to the front, and a notch is provided on the convex ring 9 in an annular direction; a plurality of clamping arms 2 are annularly hinged on the outer wall of the cylinder 1 through a hinge structure, and the free ends of the clamping arms 2 extend to the rear of the cylinder 1 and are provided with a pulley 8;

[0008] A tension spring 5 is provided between the middle of each clamp arm 2 and the outer wall of the cylinder 1. The tension spring 5 and the clamp arm 2 are in the same plane. The connecting end of the tension spring 5 and the cylinder 1 is provided on one side of the hinge structure adjacent to the convex ring 9, and is used to pull the clamp arm 2 apart.

[0009] The cable 13 passes through the cylinder 1. When the cable 13 is laid in the pipe 12, one end of the clamping arm 2 provided with the pulley 8 is supported in the pipe 12, and the cylinder 1 and the cable 13 slide as a whole.

[0013] Preferably, the length of the clamping arm 2 is greater than the distance from the hinge structure to the rear end of the cylinder 1 .

[0014] The method for using the telescopic cable laying device with adaptive guidance comprises the following steps:

[0015] Step 1: Pass the cable 13 through the cylinder 1 of several devices and fix them;

[0016] Step 2: Insert the cable 13 from one end of the pipe 12. Before each device enters the pipe 12, retract the clamp arm 2 toward the center of the cylinder 1 until the device enters the pipe 12.

[0017] Step 3: When the cable 13 needs to be disassembled, the cable 13 and the device fixed thereon are pulled out from one end of the pipe 12.

The guiding and clamping mechanism provided by the device can ensure that the cable is evenly stressed during the laying process, reduce direct friction with the pipeline wall, thereby reducing wear and potential damage to the cable and extending the service life of the cable, because the possibility of cable damage is reduced; at the same time, by arranging a convex ring with an outer diameter that gradually decreases from the back to the front at the front end of the cylinder, the probability of friction damage between the front end of the cylinder and the pipeline is further reduced. By arranging a notch on the convex ring, the convex ring can be deformed to a certain extent, thereby increasing its service life. In the long run, it can reduce material waste and subsequent maintenance costs, and has good economic benefits.

[0021] 3) The utility model facilitates rapid deployment and disassembly, so that the cables can be quickly and continuously laid in a predetermined pipeline, which significantly improves work efficiency compared with the traditional manual laying method; the simple operation also means reducing the safety risks caused by improper operation and improving the safety of on-site construction.

[0028] The utility model is further described below in conjunction with the embodiments. The description of the following embodiments is only used to help understand the utility model. It should be pointed out that for ordinary people in this technical field, the utility model can also be modified in some ways without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.

[0029] Embodiment 1

[0030] As an example, Figures 1 to 5 As shown, this telescopic cable laying device with adaptive guidance includes: a cylinder 1, the cylinder 1 is axially penetrated, a convex ring 9 is provided at the front end of the cylinder 1, the outer diameter of the convex ring 9 gradually decreases from the back to the front, which can reduce the probability of friction damage between the front end of the cylinder 1 and the inner wall of the pipe 12, and a notch is provided on the convex ring 9 in an annular direction, so that the convex ring 9 can be deformed to a certain extent; a plurality of clamping arms 2 are circumferentially hinged on the outer wall of the cylinder 1 through a hinge structure, and the hinge structure includes a protrusion 6 and a connecting rod 10, the protrusion 6 is fixed to the outer wall of the cylinder 1, and the protrusion 6 is located on the side of the first connecting seat 3 away from the protrusion 9, and a receiving groove is provided at the end of the clamping arm 2 away from the moving component, and the connecting rod 10 is connected to the receiving groove, and the connecting rod 10 passes through the protrusion 6 and rotates in the protrusion 6.

[0031] The free end of the clamping arm 2 extends to the rear of the cylinder 1 and is provided with a pulley 8; the free end of the clamping arm 2 is provided with a groove 7, and the pulley 8 is installed in the groove 7. A bearing 11 is installed on the inner ring of the pulley 8 to facilitate sliding and reduce resistance, and the rotating axis of the pulley 8 is perpendicular to the length direction of the clamping arm 2.

[0032] A tension spring 5 is provided between the middle of each clamp arm 2 and the outer wall of the cylinder 1 as a guide device. The guide mechanism can change the extension angle of the clamp arm 2 to adapt to pipes 12 with different inner diameters. Specifically, a first connecting seat 3 is provided on the outer wall of the cylinder 1, and a second connecting seat 4 is provided on the side of the middle of the clamp arm 2 facing outward. The two ends of the tension spring 5 are respectively connected to the first connecting seat 3 and the second connecting seat 4. The tension spring 5 and the clamp arm 2 are in the same plane, and the connecting end of the tension spring 5 and the cylinder 1 is provided on the side of the hinge structure adjacent to the convex ring 9, which is used to pull the clamp arm 2 apart; because the spring 5 continuously provides tension, the clamp arm 2 can be extended or retracted, so that the pulley 8 always moves in contact with the inner wall of the pipe according to the inner diameter of the pipe 12, so as to adapt to pipes with different diameters and curvatures. Therefore, it has high applicability and can be applied to a variety of different construction environments and cable specifications, reducing the demand for a variety of different equipment in the project.

[0033] The length of the clamp arm 2 is greater than the distance from the hinge structure to the rear end of the cylinder 1, so that the clamp arm 2 still protrudes from the rear end of the cylinder 1 after opening, and the rear end of the cylinder 1 will not directly contact the inner wall of the pipe 12, thereby avoiding wear and tear of the device and friction damage to the inner wall of the pipe 12.

[0034] The cable 13 passes through the cylinder 1. When the cable 13 is laid in the pipe 12, one end of the clamping arm 2 provided with the pulley 8 is supported in the pipe 12, and the cylinder 1 and the cable 13 slide as a whole.

[0035] Embodiment 2

[0036] As another embodiment, this embodiment 2 is proposed on the basis of the embodiment 1. The method for using the telescopic cable laying device with adaptive guidance is composed only of mechanical parts and does not need to rely on complex electronic control systems or software, which greatly simplifies the training requirements and operation procedures of operators, making the cable laying process easier to control and execute; and includes the following steps:

[0037] Step 1: Pass the cable 13 through the cylinders 1 of several devices and fix them; according to the degree of curvature of the pipeline 12, set the distance between the devices on the cable 13.

[0038] Step 2: Insert the cable 13 from one end of the pipe 12. Before each device enters the pipe 12, retract the clamp arm 2 toward the center of the cylinder 1 until the device enters the pipe 12. The tension spring 5 pulls the clamp arm 2 open until the pulley 8 at the end of the clamp arm 2 contacts the inner wall of the pipe 12.

[0039] Step 3: When the cable 13 needs to be disassembled, the cable 13 and the device fixed thereon are pulled out from one end of the pipe 12. When each device is pulled out from the end of the pipe 12, the tension of the tension spring 5 automatically restores the clamp arm 2; the device is disassembled from the cable 13 and used for the next construction. Since the device has a simple structure, the manufacturing and maintenance costs are low, and since the possibility of damage to the cable 13 is reduced, in the long run, material waste and subsequent maintenance costs can be reduced, which has good economic benefits; simple operation also means reducing safety risks caused by improper operation and improving on-site construction safety.

[0040] Embodiment 3

[0041] As another embodiment, this embodiment three proposes, on the basis of embodiment two, a more specific method for using a telescopic cable laying device with adaptive guidance.

[0042] In the straight pipe 12, several clamping arms 2 on the cylinder 1 are symmetrically opened to support the cable 13 in the center of the pipe 12, so that the cable 13 will not come into direct contact with the inner wall of the pipe 12, thereby avoiding safety accidents such as electrical short circuit caused by local damage to the cable 13.

[0043] Furthermore, when there is a curved portion in the pipe 12, such as Figure 3As shown, by setting the density of the devices on the cable 13 and controlling the distance between the devices, a plurality of the devices are used to form a multi-body centipede, which can realize the corner-crossing function. When the cable 13 moves in the curved pipe 12, the exposed parts of the cable 13 between the devices will not be scratched against the inner wall of the pipe 12. The several clamping arms 2 on the cylinder 1 at the curved position are asymmetrically opened, but can all be supported on the inner wall of the pipe 12, so that the device is roughly maintained in the center of the pipe 12.

[0044] When the inner diameter of the pipe 12 changes, the free end of the clamp arm 2 is squeezed and radially contracts or expands toward the cylinder 1, automatically adapting to the size of the pipe 12. Each clamp arm 2 is independently hinged to the cylinder 1, so it can also cope with pipes 12 with irregular internal shapes.

[0045] It should be noted that the parts in this embodiment that are the same or similar to those in the second embodiment can be referenced to each other and will not be described in detail in this application.

[0046] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
