Description

Technical Field

[0001] This utility model relates to the technical field of cable laying tools, specifically a support frame for high-altitude laying of large-section cables. Background Technology

[0002] When laying cables at high altitudes, the cables need to be gradually lifted. Large-section cables are heavy, increasing the difficulty of lifting. Traditional lifting methods use support frames with rollers. However, there are many uncontrollable factors during the cable lifting process. To increase laying efficiency, the laying machine power is generally selected to be high. This can lead to increased cable swaying in the air when the cable lifting speed is too fast. Without cable fixing measures, the cable lifting device may derail, causing severe friction between the cable and the support frame, damaging the cable sheath and affecting its service life. If the impact force generated when the cable derails is large, these support frames, constructed from scaffolding, are easily damaged, causing them to loosen and collapse, destroying the entire cable lifting system and directly affecting the efficiency and safety of cable laying. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a support frame for high-altitude laying of large-section cables. This frame, in conjunction with a lifting support frame, ensures the stability of the cable during lifting and provides guidance and support for the cable. The technical solution adopted by this utility model is as follows:

[0004] A support frame for high-altitude laying of large-section cables includes a horizontal mounting frame and a vertical support frame. The upper end of the support frame is mounted on the mounting frame. The support frame is provided with three rotatable rollers arranged in a triangular pattern. Connecting seats are provided on the left, right and top sides of the support frame. The two ends of each roller are respectively installed between adjacent connecting seats. The cable passes through the area enclosed by the three rollers.

[0005] The aforementioned support frame for high-altitude laying of large-section cables includes a connecting seat comprising a base plate and two side plates. The base plate is connected to the upright frame, and the two side plates are arranged at an obtuse angle and are respectively used to connect corresponding rollers.

[0006] The aforementioned support frame for high-altitude laying of large-section cables has a through hole in the center of the roller shaft to allow it to rotate through the screw rod, and both ends of the screw rod are screwed to the connecting seat.

[0007] The support frame for high-altitude laying of large-section cables mentioned above has three rollers arranged in an equilateral triangle.

[0008] The beneficial effects of this utility model are as follows: the support frame is equipped with three rollers, which can support and guide the cable during lifting, greatly reducing cable damage and derailment, and also reducing the impact on the supporting lifting frame, thus improving construction safety and efficiency.

[0013] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings. The following embodiments are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical terms used have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should be noted that the terminology used is for describing specific embodiments only and is not intended to limit the scope of this application.

[0014] This embodiment is a support frame for high-altitude laying of large-section cables, such as... Figure 1 As shown, the support frame includes a horizontal mounting frame 1 and a vertical support frame 2. When viewed from the side, the support frame is shaped like a "7". The upper end of the support frame 2 is mounted on the mounting frame 1. Both the mounting frame 1 and the support frame 2 are welded from angle steel, making the materials readily available.

[0015] The upright frame 2 is equipped with three rotatable rollers 5 arranged in a triangle. Connecting plates 3 are welded to the left, right, and top sides of the upright frame 2, and each connecting plate 3 is fitted with a connecting seat 4. Specifically, as shown... Figure 2 As shown, the connecting seat 4 includes a base plate 41 and two side plates 42. The base plate 41 is bolted to the connecting plate 3 for easy replacement and adjustment. The two side plates 42 are arranged at an obtuse angle. The two ends of each roller 5 are respectively installed between the side plates 42 of the adjacent connecting seat 4. The cable passes through the area enclosed by the three rollers 5. Preferably, the three rollers 5 are distributed in an equilateral triangle to improve the ease of installation.

[0016] Specifically, the roller 5 has a through hole in its shaft to rotate through the screw, and both ends of the screw are screwed to the connecting seat 4.

[0017] When using this support frame, if Figure 3As shown, the mounting bracket 1 (the black 7-shaped component in the figure) is installed on the support lifting bracket 8. The cable 7 is pulled out from the cable reel 6 and lifted. When it reaches the support lifting bracket 8, it passes through the support frame. The support frame supports and guides the cable 7 to avoid problems such as the cable 7 shaking and derailing, thus ensuring stability.

[0018] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various changes or improvements without departing from the principles of this application, and these changes or improvements should also be considered within the scope of protection of this application.
