Description

Technical Field

[0001] This utility model relates to the field of high mast lighting technology, specifically to a high mast lighting lifting rope divider. Background Technology

[0002] With the development of urban infrastructure, the demand for efficient lighting in large outdoor plazas, docks, freight yards, airports, and other locations is increasing. Rising high-mast lights are widely used due to their wide lighting range and convenient maintenance. Their principle is to use a lifting mechanism to raise or lower steel wire ropes, which drive the light panel to move up and down along the light pole. The steel wire ropes are divided into main and auxiliary steel wire ropes that connect vertically, and a rope separator is the component that connects the main and auxiliary steel wire ropes.

[0003] The existing high-mast lighting lifting mechanism has problems with the wire rope spinning and cable tangling. The reason is that the wire rope is under tension during the lifting process, which generates internal stress, causing the wire rope to rotate and drive the rope separator to rotate, thus causing the wire rope and cable to entangle. Utility Model Content

[0004] The purpose of this invention is to provide a high-mast light lifting rope separator to eliminate the problem of wire rope and cable entanglement caused by the rotation of the wire rope.

[0005] This utility model adopts the following technical solution: a high-mast light lifting rope separator, comprising: The main connecting plate has a central hole at its shaft and multiple evenly distributed side holes around its perimeter.

[0011] A high-mast light lifting rope divider, comprising: The main connecting plate has multiple sets of evenly distributed outer holes around its perimeter; multiple evenly distributed inner holes are also provided on the main connecting plate inside the outer holes. A cable pull plate, fixed on the main connecting plate, is used to secure the cable. The main connecting plate has a forward-arranged pull rope connecting assembly installed in the outer hole and a reverse-arranged pull rope connecting assembly installed in the inner hole.

It should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation.

[0028] Example 1: like Figures 1 to 3 As shown, this utility model provides a high-mast light lifting rope divider, including a main connecting plate 1 and a cable pull plate 2 and a rope connecting assembly 4 installed on the main connecting plate 1.

[0029] The main connecting plate 1 is a disc with a central hole at its axis and three side holes evenly distributed around its axis. A forward-facing pull rope connecting assembly 4 is installed in the side holes of the main connecting plate 1, and a reverse-facing pull rope connecting assembly 4 is installed in the central hole of the main connecting plate 1. The forward-facing and reverse-facing pull rope connecting assemblies 4 have the same structure but are arranged in opposite directions.

[0030] Taking the forward-arranged pull rope connection assembly 4 installed in the side hole of the main connecting plate 1 as an example: The pull rope connection assembly 4 includes a pull rod 41 that passes through a side hole in the main connecting plate 1, and the pull rod 41 can slide up and down along the side hole. An adjusting nut 43 is threadedly connected to the lower end of the pull rod 41. A spring 42 is fitted onto the pull rod 41, and retaining rings 44 fitted onto the pull rod 41 are respectively provided at both ends of the spring 42. Under the elastic force of the spring 42, the retaining rings 44 on both sides are respectively attached to the main connecting plate 1 and the adjusting nut 43. A wire rope fixing member 3 for connecting the wire rope is provided at the upper end of the pull rod 41. Combined Figure 4As shown, the wire rope fixing component 3 includes a hinge seat 31 hinged to the end of the tie rod 41, with a through conical hole at the upper end of the hinge seat 31; a conical block 32 is inserted from the lower end of the conical hole and fits with the inner wall of the conical hole; grooves are opened on both sides of the conical block 32; when connecting the wire rope, the wire rope is wound around the conical block 32 and clamped between the conical block 32 and the inner wall of the conical hole; the wire rope fixing component 3 adopts a wedge fixing structure, which has high reliability and is easy to install.

[0031] The cable pull plate 2 is located on the upper side of the main connecting plate 1. The cable pull plate 2 is vertically welded and fixed to the axis of the main connecting plate 1. The lower end of the cable pull plate 2 has a clearance groove that cooperates with the pull rope connection assembly 4. A cable fixing component 5 is provided on one side of the upper end of the cable pull plate 2. The cable fixing component 5 includes a base block 51 and a pressure block 52 that are fixed together to the cable pull plate 2 by screws. A through hole is provided at the contact surface of the base block 51 and the pressure block 52. The two ends of the through hole are designed with rounded corners to avoid stress concentration. The cable passes through the through hole between the base block 51 and the pressure block 52 and is pressed tightly onto the base block 51 by the pressure block 52. The cable is clamped in the entire circumference, with a large contact area, uniform cable stress, and safe and reliable operation.

[0032] The rope splitter provided in this embodiment realizes the connection design of one main rope pulling three. One main steel wire rope is fixed by the reverse-arranged pull rope connection component 4, and one auxiliary steel wire rope is fixed by the three forward-arranged pull rope connection components 4 respectively. Among them, the pull rope connection component 4 integrates a buffer function. The spring 42 can play a role in lifting and starting, buffering at extreme positions, and self-adjusting when the wire rope length is uneven. Together with the rotatable pull rod 41, it releases the internal force of the wire rope rotation, which can eliminate the influence of the wire rope spinning and prevent the wire rope from getting tangled with the cable.

[0033] Example 2: Based on the above embodiment one, combined with Figures 5 to 8 As shown, the difference between this second embodiment and the first embodiment is: The rope separator adopts a two-to-six main rope connection design. Three sets of outer holes, evenly distributed around the axis of the main connecting plate 1, are opened around the periphery of the main connecting plate 1, with each set consisting of two outer holes. Two inner holes, evenly distributed around the axis of the main connecting plate 1, are opened on the main connecting plate 1 inside the outer holes. A forward-arranged pull rope connecting assembly 4 is installed in the outer holes of the main connecting plate 1, and a reverse-arranged pull rope connecting assembly 4 is installed in the inner holes of the main connecting plate 1. Figure 6 , Figure 7 As shown, in this embodiment, the reverse-arranged pull rope connection assembly 4 does not have a wire rope fixing component 3, but instead directly fixes and presses the rope head 8 at the lower end of the pull rod 41 to achieve a fixed connection with the main wire rope.

[0034] Additionally, a secondary connecting plate 6 is arranged parallel to the main connecting plate 1 on its lower side. The secondary connecting plate 6 is fixed to the main connecting plate 1 by three screw assemblies 7 evenly distributed around the axis of the main connecting plate 1. The secondary connecting plate 6 has clearance holes corresponding to the inner holes of the main connecting plate 1, allowing the main wire rope to pass through. A locking plate 61 is fixed to the lower side of the secondary connecting plate 6, and the locking plate 61 cooperates with the locking mechanism at the bottom of the high mast light; for example, the locking plate 61 and the entire rope divider are locked to the bottom of the high mast light by a pin, facilitating installation and maintenance.
