Description

Technical Field

[0001] This utility model relates to the field of cable construction equipment technology, and in particular to a cable laying device. Background Technology

[0002] Due to my country's rapid economic development, construction and installation projects in petrochemical, power, civil engineering, and metallurgy industries often have short construction periods and heavy workloads. In these projects, the amount of cable laying work is considerable, characterized by its large quantity and variety of specifications. The speed of cable laying directly affects the speed of on-site electrical installation. Under these circumstances, cable laying in electrical installation is even more critical, and the slightest carelessness can affect the electrical installation schedule and even the overall project schedule.

[0003] Traditional cable laying devices often use fixed supports or simple rollers, which have the following problems: the cable reel may become uncontrollable due to inertia during high-speed laying, which can easily lead to safety accidents when unattended; the supports are too bulky, making the installation and transportation of the device inconvenient; and the lack of effective damping design can cause damage to the cable surface during laying. Improvements are urgently needed. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a cable laying device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cable laying device, characterized in that it comprises:

[0007] Base;

[0008] Two sets of idler rollers, each set of idler rollers includes two parallel idler rollers. The roller shafts of the idler rollers are rotatably connected to the base through bearings. The end of the roller shaft away from the idler roller is provided with a positioning pin hole and is connected to the base through the positioning pin.

[0009] A flexible damping layer is applied to the outer surface of the idler roller to limit the rotation speed of the cable reel during the cable feeding process through damping.

[0010] Preferably, the idler roller is made of thick-walled steel pipe with end plates welded to both ends, and the roller shaft is connected to the end plates.

[0011] Preferably, the base also includes a steel profile, which is detachable from the base, and the roller assembly is mounted on the steel profile via positioning pins.

[0012] Preferably, the flexible damping layer material is selected from rubber or resin materials, with a coating thickness of 5mm-15mm, to provide a uniform damping effect.

[0013] Preferably, the base is provided with multiple bearing seats, which are arranged at equal intervals along the radial direction of the cable reel.

[0014] Preferably, the surface of the flexible damping layer is provided with uniformly distributed damping patterns, which are straight stripes parallel to the axis of the idler roller or granular protrusions distributed along the circumferential direction.

[0015] Preferably, the thick-walled steel pipe has radial reinforcing ribs welded inside, and the ribs are evenly distributed along the circumference of the pipe wall.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Compared with existing technologies, the combination of flexible damping layer and rigid roller assembly ensures both the dynamic stability of the cable reel and the speed control of the cable during the laying process, preventing the cable reel from going out of control during high-speed laying and ensuring construction safety. The spacing between the rollers can be adjusted by different cable reel diameters to achieve multi-functionality. By welding ribs to the inner wall of the thick-walled steel pipe, the rigidity and reliability of the rollers can be ensured while avoiding excessive weight. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3 As shown, this embodiment provides a cable laying device, including:

[0024] Base 1;

[0025] Two sets of idlers, each set of idlers includes two parallel idlers 2. The roller shaft 5 of the idler 2 is rotatably connected to the base 1 through a bearing. The end of the roller shaft 5 away from the idler 2 is provided with a positioning pin hole 51 and is connected to the base 1 through a positioning pin 6.

[0026] The flexible damping layer 7 is wrapped around the outer surface of the idler roller 2 and limits the rotation speed of the cable reel 3 during the cable feeding process through damping.

[0027] Overall, the roller shaft 5 of the idler roller 2 is installed on the base 1 through bearings, and the positioning pin 6 is inserted into the positioning pin hole 51 to realize the installation of the idler roller 2. When the cable 4 is laid out, the flexible damping layer 7 covering the outer surface of the idler roller 2 can suppress the inertial rotation of the cable reel 3 and prevent the speed of the cable 4 from getting out of control during the laying process. This can not only ensure the safety of construction, but also reduce the need for special personnel to supervise.

[0028] like Figure 3 As shown, in this embodiment, the idler roller 2 is made of thick-walled steel pipe, and end plates 8 are welded to both ends, with the roller shaft 5 connected to the end plates 8.

[0029] Specifically, the idler roller 2 is constructed from a thick-walled steel pipe, with end plates 8 welded to both ends of the thick-walled steel pipe. This ensures the overall rigidity of the idler roller 2 so that it can support the cable reel 3, while the tubular design allows the entire device to be lightweight, reducing the maintenance frequency.

[0030] like Figures 1-2 As shown, in this embodiment, the base 1 also includes a steel profile 11, which is detachable from the base 1. The roller 2 group is installed on the steel profile 11 by a positioning pin 6.

[0031] By implementing a detachable design for the steel profile 11 and the base 1, the entire device can be modularly assembled, which facilitates the transportation of various components and rapid deployment on site. Different specifications of steel profile 11 can also be replaced according to different sizes of cable reels 3, thereby improving the versatility and adaptability between devices.

[0032] like Figure 3 As shown, in this embodiment, the flexible damping layer 7 is made of rubber or resin material, with a coating thickness of 5mm-15mm, to provide a uniform damping effect.

[0033] Specifically, the flexible damping layer 7 is made of rubber or resin, and the coating thickness is selected and replaced according to the actual use. There are no restrictions here. The material's self-adaptability can compensate for the unevenness of the cable reel 3 surface and maintain the uniformity of the cable 4 speed during the laying process. This can reduce the damage to the cable 4 during the laying process and improve the laying efficiency of the cable 4.

[0034] like Figures 1-2As shown, in this embodiment, the base 1 is provided with multiple bearing seats, which are arranged at equal intervals along the radial direction of the cable reel 3.

[0035] By setting multiple bearing seats, the spacing between the two parallel rollers 2 can be appropriately adjusted according to the diameter of the cable reel 3, and positioned by the positioning pin 6, which can meet the needs of cable reels 3 of different diameters and significantly improve construction efficiency.

[0036] like Figures 2-3 As shown, in this embodiment, the surface of the flexible damping layer 7 is provided with uniformly distributed damping patterns, which are straight stripes parallel to the axis of the idler roller 2 or granular protrusions distributed along the circumferential direction.

[0037] By setting straight stripes to provide directional frictional resistance, it is suitable for high-speed cable laying scenarios; while by setting particle protrusions on the surface of the flexible damping layer 7 and forming multi-point contact, the anti-slip ability of the cable 4 at low speeds during cable laying is enhanced. The design of the pattern can be flexibly selected according to the different materials of the cable 4, and there are no restrictions here.

[0038] like Figure 3 As shown, in this embodiment, radial reinforcing ribs are welded inside the thick-walled steel pipe, and the ribs are evenly distributed along the circumference of the pipe wall.

[0039] Specifically, the internal welding of reinforcing ribs into the thick-walled steel pipe can improve the overall strength of the thick-walled steel pipe. By evenly distributing the ribs along the axial direction of the pipe wall, the concentrated load received by the idler roller 2 can be distributed to the three pipe walls, avoiding local deformation of the thick-walled steel pipe, ensuring the balance of the idler roller 2 during rotation, and reducing the risk of bearing wear.

[0040] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
