Description

Technical Field

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

[0002] A cable laying rack is a device used to place and support cables. It is commonly used in construction sites, power construction, or communication engineering. It is usually made of lightweight materials such as metal or plastic, and has a reasonable structural design that is easy to carry and set up. It is used to store and organize cables, preventing them from becoming messy, tangled, or damaged, thereby improving construction efficiency and work safety. For example, a cable reel laying rack with patent publication number CN223032735U has an adjustment component consisting of a bidirectional screw and a guide rod, which allows for adjustment of the distance between two support plates. This allows it to accommodate cable reels of different diameters, improving the versatility of the equipment to some extent. However, the cable reel and the support rollers experience sliding friction, which is not conducive to smooth cable laying. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a cable laying device that can effectively reduce the frictional resistance during the laying process and adapt to the axial limiting requirements of laying drums of different specifications.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A cable laying device includes a base and a support. A cable laying drum is mounted on the support. The support includes movable frames on both sides of the base. Each movable frame is provided with a limiting plate. The cable laying drum is rotatably mounted between the two movable frames and is limited by the limiting plates on both sides. The limiting plates are provided with a rolling device to reduce the frictional resistance when the cable laying drum rotates.

[0006] Furthermore, a fixed rod is provided between the moving frames, and a mounting hole is provided in the center of the pay-off drum. A bearing is pressed into the mounting hole, and the pay-off drum is supported on the fixed rod by the bearing to reduce the rotational friction of the pay-off drum.

[0007] Furthermore, the rolling device is a ball bearing, which is located on the contact surface between the limiting plate and the end of the feed drum.

[0008] Furthermore, the movable frame is equipped with a screw and a limiting rod. The screw is threadedly connected to the movable frame and its end is rotatably connected to the limiting plate. The limiting rod passes through the movable frame and is connected to the limiting plate. By rotating the screw, the limiting plate is driven to move, thereby adjusting the distance between the two limiting plates.

[0009] Furthermore, the mobile frame is equipped with a fixed base, and the two ends of the fixed rod are fixed inside the fixed base.

[0010] Furthermore, a lifting device is provided on the base, and the output end of the lifting device is connected to the movable frame to drive the movable frame and the wire feeding drum to lift and lower, so as to avoid friction between the wire feeding drum and the base when the wire feeding drum rotates.

[0011] Furthermore, the base is located on the pedestal, and the base and the pedestal are connected by a rotating rod. The pedestal is equipped with a slide rail, and the base is equipped with a fixing frame. The end of the fixing frame is embedded in the slide rail, so that the base can rotate along the slide rail.

[0012] Furthermore, a motor is installed on the base, and the output end of the motor is connected to a drive gear. A driven gear is installed on the rotating rod. The base is driven to rotate through the meshing of the drive gear and the driven gear.

[0013] Furthermore, guide rails are provided on the sides of the base.

[0014] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0015] 1. In this utility model, by setting a matching structure between the fixed rod and the bearing, the sliding friction between the wire reel and the support is transformed into rolling friction inside the bearing, which significantly reduces the rotational resistance and makes the wire feeding process more labor-saving and smoother, especially suitable for wire feeding operations of heavy cable reels;

[0016] 2. In this utility model, by setting a ball bearing on the limiting plate as a rolling device, it contacts the end face of the pay-off drum but does not bear weight. While providing effective axial limiting, it further reduces the frictional resistance when the end face of the pay-off drum rotates, avoids the additional friction caused by axial limiting in the traditional structure, and ensures the stability and efficiency of the pay-off process.

[0017] 3. In this utility model, by setting a movable frame driven by a lifting device, not only can the wire-feeding drum be raised to avoid friction with the base, but the height of the movable frame can also be adjusted to quickly align the through hole of the fixed seat with the mounting hole of the wire-feeding drum, which greatly simplifies the installation and positioning process of the heavy-duty wire-feeding drum and improves the convenience and safety of operation.

[0018] 4. In this utility model, the adjustment mechanism composed of the screw and the limiting rod can flexibly drive the limiting plates on both sides to move towards or away from each other, thereby precisely adjusting their spacing. This allows the device to stably adapt to cable reels of different widths, enhancing the versatility of the equipment and meeting diverse construction needs. Attached Figure Description

Detailed Implementation

[0026] like Figures 1 to 5 As shown, this utility model provides a cable laying device. The device includes a base 14 and a base 1. A support 2 is provided on the upper surface of the base 1, and a cable laying drum 3 for releasing cables is supported on the support 2.

[0027] The support 2 includes a movable frame 4 symmetrically and movably mounted on the base 1. The top surface of the movable frame 4 is provided with a fixed seat 12. The fixed seat 12 has a through hole in its center. The center of the wire feeding drum 3 is provided with a mounting hole 8 corresponding to the through hole. A rolling bearing 9 is pressed into the mounting holes 8 at both ends of the wire feeding drum 3. It can be set as a deep groove ball bearing 9.

[0028] Move the pay-off spool 3 between the two movable frames 4, aligning the inner holes of the bearings 9 at both ends with the through holes on the fixed base 12. Then, insert one end of the fixing rod 7 into the through hole of one side of the fixed base 12, and then sequentially pass through the inner holes of the bearings 9 at one end of the pay-off spool 3 and the inner holes of the bearings 9 at the other end, finally exiting through the through hole of the other side of the fixed base 12. After the fixing rod 7 is in place, its two ends can be fixed to the fixed base 12 by means of pins, set screws, or other quick-locking mechanisms, thus making the fixing rod 7 a stationary load-bearing shaft. The pay-off spool 3 is supported on the fixing rod 7 by the bearings 9 at both ends, converting sliding friction into rolling friction inside the bearings 9, thereby reducing rotational resistance.

[0029] In order to effectively limit the axial movement of the wire feeding drum 3, limit plates 5 are provided on both sides of the moving frame 4 to clamp the drum from both sides.

[0030] A rolling device 6 is provided at the contact point between the limiting plate 5 and the end face of the feeding drum 3 to reduce the frictional resistance when the feeding drum 3 rotates.

[0031] The rolling device 6 includes multiple balls 61. The end face of the limiting plate 5 facing the wire feeding drum 3 is provided with a groove, and the balls are provided in the groove. The balls 61 are partially assembled in the groove and protrude from the end face of the limiting plate 5 and contact the end face of the wire feeding drum 3.

[0032] To further secure the ball bearing 61 and ensure its normal rolling, the rolling device 6 also includes a retainer. The retainer is disposed within a groove and has retaining holes corresponding to the balls, in which the balls 61 are embedded. The retainer is detachably mounted on the limiting plate 5 by screws, facilitating the maintenance and replacement of the balls 61. Through this structure, the balls 61 can generate rolling friction between the limiting plate 5 and the end face of the feed drum 3, effectively reducing the frictional resistance when the feed drum 3 rotates, while ensuring the reliability of axial positioning.

[0033] The movable frame 4 is symmetrically provided with connecting seats at both ends. The connecting seats are located on both sides of the fixed seat 12, and a screw 10 and a limiting rod 11 are respectively installed on the connecting seats on both sides. The screw 10 is threadedly connected to the connecting seat, and one end is rotatably connected to the limiting plate 5. The limiting rod 11 moves through the connecting seat, and one end is fixedly connected to the limiting plate 5. By rotating the screw 10, the limiting plate 5 can be driven to move along the limiting rod 11, thereby flexibly adjusting the distance between the two limiting plates 5 to accommodate different specifications of spools.

[0034] A lifting device 13 is installed on the base 1. The lifting device 13 can be set as an electric push rod or a cylinder. The cylinder can be an Airtac MY series standard cylinder.

[0035] The output end of the lifting device 13 is connected to the movable frame 4, which can drive the movable frame 4 and the wire feeding drum 3 to lift.

[0036] The lifting device 13 moves the wire feeding drum 3 upward and separates it from the base 1 to prevent the wire feeding drum 3 from rubbing against the base 1 when it rotates.

[0037] Meanwhile, the height of the movable frame 4 can be adjusted by setting the lifting device 13, and the through hole of the fixed seat 12 on the movable frame 4 can be aligned with the mounting hole 8 on the wire feeding drum 3, which facilitates the installation of the fixed rod 7.

[0038] The base 1 is connected to the base 14 below via a rotating rod 15. The base 14 is provided with an arc-shaped slide rail, and the base 1 is provided with a fixing frame 17. The base 1 can rotate along the slide rail by the fitting of the end of the fixing frame 17 with the slide rail, thereby flexibly adjusting the wire feeding direction.

[0039] The base 1 can be automated by driving the motor 18, that is, the motor 18 is fixed on the base 14, and the motor 18 can be a Delta ECMA series AC servo motor 18.

[0040] The output end of the motor 18 is fixedly connected to the drive gear 19, and the driven gear 20 is installed on the rotating rod 15. The drive gear 19 and the driven gear 20 mesh, and the base 1 can be rotated by the motor 18.

[0041] An auxiliary guide rail 21 is provided on the side of the base 14. A support seat is provided on the bottom surface of the guide rail 21. One end of the guide rail 21 is attached to the edge of the base 1, and the other end is placed on the ground through the support seat at the bottom. The angle between the guide rail 21 and the ground can be set according to the actual situation to facilitate the movement of the wire feeding drum 3 to the working position of the bracket 2.

[0042] Meanwhile, a support rod is provided on the bottom surface of the guide rail 21, and a groove corresponding to the support rod is provided on the base 14. By inserting the support rod into the groove, the position of the guide rail 21 is fixed, preventing the guide rail 21 from separating from the base 1 when the wire feeding drum 3 is transferred to the bracket 2 via the guide rail 21, thus facilitating the installation of the wire feeding drum 3.

[0043] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
