Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically a cable culvert corner laying device. Background Technology

[0002] During cable installation, corners are inevitable. Directly dragging the cable can easily damage the cable sheath, and it also creates significant resistance, making it time-consuming and labor-intensive. To protect the cable sheath and ensure smooth subsequent cable laying, auxiliary laying devices are typically used. Chinese patent document CN218828813U discloses an adjustable-angle cable laying device for corners, including an upper bracket, a lower bracket, and a screw. Both the upper and lower brackets consist of two side plates and a horizontal plate connecting the side plates. Screw holes are opened at the top and bottom ends of the side plates of both the upper and lower brackets. The screw holes at the bottom of the upper bracket and the bottom of the lower bracket overlap, and the screw passes through both screw holes. A first pulley is connected between the screw holes at the top of the upper bracket, and a second pulley is connected between the screw holes at the top of the lower bracket. First, this structure is only suitable for corners in the vertical direction; it cannot be used for corners in the horizontal plane. Second, in the horizontal direction, the cable can easily slip out of the device. Chinese patent document CN222107551U discloses a protective device for cable laying in energy storage systems at corners, comprising: a mounting post; a support component that uses the corner as a support point to clamp the mounting post in the corner, the support component cooperating with the mounting post; and rollers A, B, and C rotatably mounted on the mounting post. Rollers A and C are circumferentially distributed with the same diameter, and roller B is located outside the circumferential distribution trajectory of rollers A and C. This ensures that during cable laying, the cable enters the contact roller B tangentially from roller A and exits tangentially from roller C. Rollers A and C provide rolling limit on one side of the cable, and roller B provides rolling limit on the other side. With the corresponding rolling limit provided by rollers A, C, and B on both sides of the cable, the cable is laid at the corner of the trench, preventing contact with the corner during bending and turning, thus solving the problem of cable elasticity extending outwards to the corner and causing wear. This structure is suitable for corners in a horizontal plane. However, when laying the cable, it is supported by rollers in the horizontal plane but not in the vertical direction. The cable is prone to friction with the support components, which increases resistance and may damage the cable sheath. Utility Model Content

[0003] The purpose of this utility model is to provide a cable culvert corner laying device with a simple structure that can provide good support for cables, protect cables, and reduce the labor required for laying.

[0004] The basic technical solution for achieving the purpose of this utility model is: a cable culvert corner laying device, including a base, characterized in that it further includes a mounting frame assembly, a support assembly, and an adjustment assembly. The mounting frame assembly is rotatably mounted on the base via a plane bearing.

[0005] The support assembly includes 2 to 5 sets of omnidirectional ball bearings, arranged sequentially from back to front along the cable transport direction. Each set of omnidirectional ball bearings is spaced at equal intervals along the cable's circumference, thus providing axial and radial support for the cable. Each omnidirectional ball bearing is adjustable on the mounting bracket assembly via an adjustment mechanism.

[0006] Furthermore, to facilitate cable installation: the mounting bracket assembly includes a left mounting bracket, a right mounting bracket, and a connecting base. The lower part of the left mounting bracket is hinged to the left side of the connecting base, and the lower part of the right mounting bracket is hinged to the right side of the connecting base. The upper parts of the left and right mounting brackets are detachably and fixedly connected together by bolts.

[0007] Furthermore, to accommodate cables of different diameters, the number of adjusting components corresponds to the number of each set of universal ball bearings. Each set of adjusting components has the same structure, including an adjusting screw and an adjusting seat. Each set of adjusting components is angularly spaced along the circumference of the cable on the mounting frame assembly, and the adjusting seat is slidably mounted on the mounting frame assembly along the radial direction of the cable. A scale is provided on the adjusting seat. The adjusting screw is screwed radially onto the mounting frame assembly, and the inner end of the adjusting screw is rotatably connected to the adjusting seat. Each set of universal ball bearings in the same front-rear direction is fixedly mounted on the same adjusting seat.

[0008] The present invention has the following beneficial effects: (1) The cable culvert corner laying device of the present invention has a simple structure and can support the cable in all directions. It can not only adapt to cable turning and laying, but also be used for straight sections to avoid the cable contacting and rubbing with the ground or corner of the wall, causing damage to the cable sheath. At the same time, the laying resistance is small. (2) The cable culvert corner laying device of the present invention is equipped with an adjustment component, so it can adapt to cables of different diameters and has a wide range of applications. (3) The cable culvert corner laying device of the present invention uses universal ball bearings, which can support the cable and the rolling contact reduces resistance and improves laying efficiency.

[0015] Mounting bracket assembly 2 includes a left mounting bracket 21, a right mounting bracket 22, and a connecting seat 23. The lower part of the left mounting bracket 21 is hinged to the left part of the connecting seat 23, and the lower part of the right mounting bracket 22 is hinged to the right part of the connecting seat 23. The upper parts of the left mounting bracket 21 and the right mounting bracket 22 are detachably and fixedly connected together by bolts. The connecting seat 23 is fixedly mounted on a plane bearing 3, so that the mounting bracket assembly 2 is rotatably connected to the base 1 through the plane bearing 3.

[0016] The support assembly 4 includes 2 to 5 sets of universal ball bearings 41, with 3 to 8 universal ball bearings 41 in each set. In this embodiment, there are 3 sets. The 3 sets of universal ball bearings 41 are arranged sequentially from back to front along the cable conveying direction to support the cable axially. The universal ball bearings 41 in each set are arranged at equal intervals along the circumference of the cable to support the cable radially. In this embodiment, each set has 6 universal ball bearings 41. Each universal ball bearing 41 can be adjusted on the mounting frame assembly 2 via the adjustment assembly 5, that is, the position of each universal ball bearing 41 can be adjusted radially along the cable to accommodate cables of different diameters.
