Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a cable laying base. Background Art

[0002] Currently, a large number of cables are used in all types of buildings, including chemical, electric power, municipal, water conservancy, etc., many of which have larger diameters.

[0003] In traditional construction, cables are mainly pulled manually or mechanically. During manual or mechanical pulling, the assembled cables are heavy and cannot be moved as a whole. The cables need to be removed from the cable reel and straightened before pulling construction can be carried out. During manual or mechanical pulling, the assembled cables are heavy, making it difficult to pull and straighten them when laying out the cables, and the cable reel is prone to rolling during pulling without fixing measures.

[0004] Therefore, the utility model provides a cable laying base to solve the problems raised in the above background technology. Utility Model Content

[0008] Steel plates are fixedly arranged at the outer edge and the inner edge of the lower end surface of the auxiliary support, solid round steel is arranged between two steel plates facing each other front and back among the plurality of steel plates, and rotating rollers are rotatably sleeved on the outer sides of the plurality of solid round steels;

[0009] Through the above technical scheme, the main platform of the whole device is formed by welding H-shaped steel in the middle of the support, forming a main support with higher strength and better stability. Compared with the traditional construction without support, the rolling of the finished cable reel is reduced, which increases safety. At the same time, the higher strength also enables the utility model to adapt to finished cable reels of different weights.

[0010] Further, through holes are penetrated and provided at the midpoints of one sides of the plurality of steel plates, and one ends of the plurality of solid round steel bars are connected and arranged in the through holes by welding;

[0011] Through the above technical solution, it is beneficial to ensure the integral structure of the steel plate and the solid round steel bar.

[0012] Further, the plurality of rotating rollers are all rotatably arranged on the upper surface of the main support;

[0013] Through the above technical solution, it plays a role in reducing resistance and also plays a role in supporting the sub-support.

[0014] Further, one end of the central shaft rod penetrates through the central shaft rotary bearing, and the central shaft rotary bearing includes two rotary bearings, and the two rotary bearings are respectively embedded at the upper and lower ends of the intersection points of the plurality of H-shaped steels on the sub-support;

[0015] Through the above technical solution, the setting of the central shaft rotary bearing can further reduce the friction force during the working state.

[0016] Further, holes are provided at the midpoints of the intersection points of the plurality of H-shaped steels located inside the main support, and one end of the central shaft rod is connected to the holes at the midpoints of the intersection points of the plurality of H-shaped steels inside the main support by welding, and the central shaft rod is installed perpendicular to the entire main support platform;

[0017] Through the above technical solution, the concentric purpose is achieved by fixing with the central shaft rod and the central shaft rod rotary bearing in the middle.

[0018] Further, both the sub-support and the main support are made of circular ring channel steels, and the inner sides of the sub-support and the main support are both C-shaped structures;

[0019] Through the above technical solution, the use of a plurality of combined steel materials for assembly is adopted to avoid the use of a whole piece of steel material, and the construction cost can be saved.

[0020] The utility model has the following beneficial effects:

[0021] 1. The cable laying base proposed by the utility model forms the main platform of the whole device by welding H-shaped steel in the middle of the annular channel steel, forming a main support with relatively high strength and good stability. Compared with the traditional construction without a support, the rolling of fewer finished cable reels is reduced, the safety is increased, and at the same time, the relatively high strength also enables the utility model to adapt to finished cable reels of different weights.

[0022] 2. The cable laying base proposed in the utility model has a sub-support rotating roller welded under the sub-support, which is installed on the central axis of the H-shaped steel of the rotating sub-support to ensure the balance and stability of the rotating sub-support, and the rotating roller and the central axis rotating bearing reduce the friction between the rotating sub-support and the main support and the central axis rod under working conditions, thereby saving manpower and material resources at work and improving work efficiency. At the same time, the utility model has a strong structural rigidity, and its components are conventional equipment, which can be reused continuously, has a high utilization rate and a long life cycle, and the maintenance materials are easy to find and simple and convenient.
