Description

Technical Field

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

[0002] During the construction of construction projects, mechanical equipment and on-site lighting require a large amount of electricity, and the temporary electricity demand of the construction site must be met. Due to the relatively poor conditions at the construction site, its temporary nature and high mobility, the requirements for power load are relatively large, and therefore the requirements for the safe supply of electricity for engineering construction are higher.

[0003] At present, there are two ways to lay cables in on-site construction: manual laying and mechanical laying. When laying cables manually, the rhythm is unified and commanded. Every 1.5 to 3 meters, one person carries the cable on his shoulder and lays and pulls it slowly. When laying cables mechanically, a special cable laying machine is generally used and equipped with necessary traction tools. The traction force is appropriate and evenly controlled to avoid damaging the cable.

[0004] Before laying the cable, check whether the cable appearance and the cable heads are intact. When laying the cable, pay attention to the rotation direction of the cable reel. Do not flatten or scratch the outer sheath of the cable. Do not straighten the cable by dropping it in the low temperature in winter to avoid cracking the insulation and sheath.

[0005] The tunnel of this project is 4011m long. The electricity required for the internal structure construction must meet the progress of on-site construction. Construction cables must be laid at regular intervals. In order to meet the on-site electricity needs more conveniently and promptly, this new device is specially designed.

[0006] The existing technology for laying cables on construction sites has the following main technical problems and challenges:

[0007] 1. Efficiency issues

[0008] Manual cable laying: It requires a lot of manpower, and the laying speed is limited by the walking speed and physical strength of the manpower, so the efficiency is low. In long-distance or large-scale engineering projects, this method is particularly inefficient and it is difficult to quickly respond to changes in the construction progress.

[0009] Mechanical cable laying: Although it is more efficient than manual laying, it still requires special cable laying machines and traction tools. For smaller projects or projects with limited resources, there are issues of cost and equipment deployment.

[0010] 2. Security issues

[0011] Manual laying: When carrying cables on shoulders, the weight of the cables and the physical pressure during the laying process may cause workers to become fatigued or injured, increasing work risks.

[0012] Mechanical release: If the traction force is not properly controlled, the cable will be overstretched or twisted, damaging the internal structure of the cable, affecting the service life and safety of the cable. In addition, incorrect rotation direction and the act of dropping the cable will also cause damage to the outer sheath of the cable, increasing safety hazards during later use.

[0013] 3. Operational complexity

[0014] Human laying: It requires unified command and control of the rhythm, dispatching and management of a large number of human resources, which increases the difficulty of construction management.

[0015] Mechanical laying: Operating a dedicated cable laying machine requires professional skills, and in certain environments (such as low temperatures in winter), the physical properties of the cable will change, requiring additional measures to protect the cable, increasing the complexity of the construction.

[0016] 4. Cost considerations

[0017] Human labor installation: Although the initial investment is low, it increases labor costs in the long run, especially in areas with high human resource costs or in large-scale projects.

[0018] Mechanical placement: requires investment in special equipment and tools. For short-term or small-scale projects, the cost of purchasing and maintaining the equipment is not economical.

[0019] In summary, the existing cable laying technology has a series of problems in terms of efficiency, safety, operational complexity and cost. There is an urgent need for a new cable laying method or device to improve construction efficiency, reduce safety risks, simplify the operating process, and be economical and efficient. Utility Model Content

[0020] In view of the problems existing in the prior art, the utility model provides a convenient cable laying device.

[0021] The utility model is implemented in this way: a portable cable laying device comprises:

[0022] It is composed of central axis steel pipe, horizontal reinforcing ribs, positioning stirrups, horizontal anti-falling steel bars, vertical steel bar frame, piston and lifting ring structure;

[0023] The central axis steel pipe is 100mm in diameter, 3mm thick and 1.8m long as support.

[0024] Furthermore, two positioning stirrups are arranged at the upper and lower parts of the central axis steel pipe, three horizontal reinforcing ribs are respectively welded to the steel pipe, and four frame steel bars are vertically arranged and connected to the stirrups.

[0025] Furthermore, horizontal anti-falling steel bars are welded at the bottom of the central axis steel pipe, and the anti-falling steel bars at the middle and upper positions are connected by welding connectors. A 20mm diameter reserved hole is horizontally reserved at the top of the central axis steel pipe as a piston for placing a lifting ring.

[0026] Furthermore, the steel bars are all threaded steel bars with a diameter of 22.

[0027] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the utility model are as follows:

[0028] When laying cables manually, it is necessary to unify the command and control rhythm. Every 1.5 to 3 meters, one person carries the cable on his shoulder and pulls it slowly. When laying cables mechanically, a special cable laying machine is generally used and equipped with necessary traction tools. The traction force is appropriate and evenly controlled to avoid damaging the cable. However, this new device only requires a forklift and 2 to 3 people to complete the work, which greatly improves the efficiency of cable laying, while reducing the input of personnel and construction costs.

[0029] The new device has a clear structural principle, simple structure, and is easy to operate. The materials used are steel pipes, steel bars, and steel plates commonly used in engineering projects. The materials are easy to obtain, low in cost, and can be recycled, which conforms to the concept of economy, greenness, and environmental protection. In addition, the device is smart and can be easily transported, does not occupy too much construction site, and does not affect the normal order of on-site construction.

[0030] To lay 200 meters of large construction cables by manual dragging, it would take at least 10 people 3 hours to complete the task. However, with this new device, it only takes 3 people 1 hour to complete the task.

[0031] The device has a simple structure, and all its components are made of materials commonly used in engineering, which conforms to the concepts of economy, greenness and environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS
