Problems solved by technology

[0003] When laying long-distance existing long-span bridges, more support rods are often required to support them to prevent local collapse. At the same time, existing long-span bridges often encounter obstacles when laying , the conventional solution is to extend the bridge to bypass obstacles and continue laying. A large degree of bending is not conducive to the safety of the cable itself, so we propose an adjustable combined large-span cable tray

Embodiment 1

[0021] This embodiment provides an adjustable combined long-span cable tray, such as Figure 1-3 As shown in the figure, it includes a plurality of bridge frames 1 arranged in a transverse connection, and the upper ends of two adjacent bridge frames 1 are connected and arranged by rotating shaft 2, and a gear 3 is fixed on the rotating shaft 2, and the gear 3 and the rotating shaft 2 are set for concentric rotation. Cooperate with the gear 3, so that the adjacent bridges 1 can be rotated to change their angles, and multiple bridges 1 are rotated at the same time, so that they form an arc together, so as to bypass the corresponding obstacles and avoid the extension of the bridges 1. , saves the cost of laying, and at the same time protects the structural safety of the cable itself to a certain extent, the upper end of the gear 3 is also provided with a matching limit mechanism, and the limit mechanism includes a sliding cavity 6 fixedly arranged in the side wall of the bridge 1,...

Abstract

The invention relates to an adjustable combined large-span cable bridge, which includes a plurality of bridges connected horizontally, and the upper ends of two adjacent bridges are connected by rotating shafts, and gears are fixed on the shafts. The gear and the rotating shaft are set to rotate concentrically, and the upper end of the gear is also provided with a matching limit mechanism. The lower ends of the individual bridges are fixedly provided with support plates, and the lower ends of the support plates are fixedly provided with support rods; when the present invention is laying bridges, when obstacles are encountered, the laying of the bridges will be affected. , we can make the cable tray curved and combined to bypass obstacles, ensuring the normal laying process of the cable tray and improving the scope of application of the cable tray.

Description

technical field [0001] The invention relates to the technical field of cable trays, in particular to an adjustable combined long-span cable tray. Background technique [0002] The cable tray is composed of brackets, supporting arms and installation accessories, etc. It can be erected independently, or can be laid on various buildings (structures) and pipe gallery brackets, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized and installed in the open air bridge outside the building. If it is near the sea or in a corrosive area, the material must have the characteristics of anti-corrosion, moisture resistance, good adhesion and high impact resistance; Span cable tray is a type of bridge with larger supporting span than ordinary cable tray, and because of its exquisite structure design, it has the characteristics of larger bearing capacity than ordinary cable tray; [0003]...
