Description

Technical Field

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

[0002] Cable laying is a common and important task in many fields such as power construction and telecommunications engineering, and cable laying supports are widely used. However, existing cable laying supports have some significant shortcomings in practical operation. When it is necessary to adjust the laying direction, the existing support structure design makes the adjustment process extremely inconvenient, often requiring construction workers to expend a lot of manpower and time to complete the adjustment. This not only increases labor intensity but also reduces overall construction efficiency.

[0003] Furthermore, existing cable laying supports typically only allow for the installation of one laying roller. In large-scale projects requiring batch laying, the design of a single laying roller means that only one cable can be laid out at a time, failing to meet the need for simultaneous laying of multiple cables. This significantly impacts laying efficiency and prolongs the project's construction cycle. Therefore, there is an urgent practical need to develop a portable cable laying support that allows for easy adjustment of the laying direction and enables batch laying. Utility Model Content

[0004] The main objective of this invention is to provide a portable cable management bracket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A portable cable delivery bracket includes a base with a push handle fixed to one side and casters mounted on the bottom. A mounting cavity is formed in the base, and a steering assembly is disposed within the cavity, with a vertical rod driven through the steering assembly. A mounting plate is fixed to the top of the vertical rod, and a housing is fixed above the mounting plate, containing a cable delivery drive assembly. Connecting rods are connected to both sides of the cable delivery drive assembly, and cable delivery rollers are fitted onto the connecting rods. A limiting rod is provided at the end of the connecting rod near the cable delivery drive assembly, and a limiting groove for the limiting rod to engage is formed on the same side of the cable delivery roller. An external thread is provided at the end of the connecting rod, and a fastening nut is installed. A wire assembly is located at the lower end of the vertical rod, directly below the cable delivery roller.

[0007] Furthermore, the steering assembly includes a steering motor, a first rotating shaft, a drive gear, a second rotating shaft, and a driven gear. The steering motor is vertically positioned, and its output shaft passes through the base and extends into the mounting cavity. The output shaft of the steering motor is connected to the first rotating shaft, on which the drive gear is fixed. A vertical second rotating shaft is positioned on one side of the first rotating shaft, on which a driven gear meshing with the drive gear is fixed. The second rotating shaft rotates upward through the base and is fixedly connected to a vertical rod.

[0008] Furthermore, the wire feeding drive assembly includes a wire feeding motor, a worm gear, and a worm. The wire feeding motor is vertically fixed to the top of the housing. The output shaft of the wire feeding motor passes through the top of the housing and extends into the housing. The output shaft of the wire feeding motor is connected to the worm gear. A worm is engaged with one side of the worm gear, and the worm passes through the side plates of the housing on both sides and is fixedly connected to the connecting rod.

[0009] Furthermore, the conductor assembly includes a crossbar, a mounting bracket, and a conductor wheel. The lower end of the vertical bar is fixed with a crossbar, and the end of the crossbar is fixed with a U-shaped mounting bracket. A rotatable conductor wheel is installed at the opening of the mounting bracket.

[0010] This utility model also includes other components that enable the portable cable laying bracket to function properly, and these devices or components all employ conventional techniques in the art. Furthermore, devices and components not limited in this utility model all employ conventional techniques in the art, such as the cable laying motor and steering motor mentioned in this application. In specific implementation, appropriate device or component models can be selected according to the specific working scenario.

[0011] The working principle of this invention is as follows: the cable wound on the pay-off roller passes downward through the gap between the guide wheel and the mounting frame, and the guide wheel provides rolling support for the cable during the pay-off process. A steering motor drives a drive gear to rotate via a first shaft, which meshes with a driven gear to drive a second shaft to rotate, enabling the vertical rod to adjust the pay-off roller's position 360°. The pay-off motor drives a worm gear to rotate, which in turn drives the connecting rods on both sides to rotate synchronously. After the limiting rod is inserted into the limiting groove of the pay-off roller, it is locked by a fastening nut to achieve synchronous rotation of the pay-off roller and the connecting rods. This structure allows pay-off rollers to be installed on both sides of the pay-off drive assembly for synchronous pay-off operations, significantly improving cable laying efficiency.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. It enables 360-degree directional adjustment of the feeding roller, which facilitates the adjustment of the feeding direction and reduces manpower consumption.

[0014] 2. Allows for the installation of wire-laying rollers on both sides of the wire-laying drive assembly for synchronous operation, significantly improving cable laying efficiency.

[0015] 3. The worm gear and limit locking structure ensure synchronous rotation of the two-sided feed rollers, improving transmission stability. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example:

[0023] like Figures 1-4 As shown, a portable cable delivery bracket includes a base 1, a push handle 18 fixed to one side of the base 1, and casters 17 mounted on the bottom of the base 1. A mounting cavity 16 is formed in the base 1, and a steering assembly 3 is disposed within the mounting cavity 16. The steering assembly 3 is drivenly connected to a vertical rod 4. A mounting plate 5 is fixed to the top of the vertical rod 4, and a housing 6 is fixed above the mounting plate 5. A cable delivery drive assembly is disposed within the housing 6. Connecting rods 10 are connected to both sides of the cable delivery drive assembly, and cable delivery rollers 11 are fitted onto the connecting rods 10. A limiting rod 12 is provided at the end of the connecting rod 10 near the cable delivery drive assembly, and a limiting groove 13 for the limiting rod 12 to engage is formed on the same side of the cable delivery roller 11. An external thread 15 is provided at the end of the connecting rod 10, and a fastening nut 14 is installed thereon. A wire assembly 2 is disposed at the lower end of the vertical rod 4, directly below the cable delivery roller 11.

[0024] Specifically, the steering assembly 3 includes a steering motor 31, a first rotating shaft 32, a drive gear 33, a second rotating shaft 34, and a driven gear 35. The steering motor 31 is vertically arranged, and its output shaft passes through the base 1 and extends into the mounting cavity 16. The output shaft of the steering motor 31 is connected to the first rotating shaft 32, and the drive gear 33 is fixed on the first rotating shaft 32. A vertical second rotating shaft 34 is arranged on one side of the first rotating shaft 32, and the driven gear 35, which meshes with the drive gear 33, is fixed on the second rotating shaft 34. The second rotating shaft 34 rotates upward through the base 1 and is fixedly connected to the vertical rod 4.

[0025] The wire feeding drive assembly includes a wire feeding motor 7, a worm gear 8, and a worm 9. The wire feeding motor 7 is vertically fixed to the top of the housing 6. The output shaft of the wire feeding motor 7 passes through the top of the housing 6 and extends into the housing 6. The output shaft of the wire feeding motor 7 is connected to the worm gear 8. The worm 9 is meshed on one side of the worm gear 8. The worm 9 passes through the side plates of the housing 6 on both sides and is fixedly connected to the connecting rod 10.

[0026] The conductor assembly 2 includes a crossbar 21, a mounting bracket 22, and a conductor wheel 23. The lower end of the vertical rod 4 is fixed with the crossbar 21, and the end of the crossbar 21 is fixed with a U-shaped mounting bracket 22. A rotatable conductor wheel 23 is installed at the opening of the mounting bracket 22.

[0027] The working principle of this portable cable laying bracket is as follows: the cable 19 wound on the laying roller 11 passes downward through the gap between the guide wheel 23 and the mounting frame 22, and the guide wheel 23 provides rolling support for the cable during the laying process. The steering motor 31 drives the drive gear 33 to rotate through the first rotating shaft 32, and after meshing with the driven gear 35, it drives the second rotating shaft 34 to rotate, so that the vertical rod 4 drives the laying roller 11 to achieve 360° directional adjustment. The laying motor 7 drives the worm gear 8 to rotate, and the worm 9 drives the connecting rods 10 on both sides to rotate synchronously. After the limiting rod 12 is embedded in the limiting groove 13 of the laying roller 11, it is locked by the fastening nut 14 to achieve synchronous rotation of the laying roller 11 and the connecting rod 10. This structure allows the laying roller 11 to be installed on both the left and right sides of the laying drive assembly for synchronous laying operations, which significantly improves the cable laying efficiency.
