Description
Pulling device for cable installation The present invention relates to a cable laying traction device, and more specifically, to a cable laying traction device that can be installed in a cable collection section called a cable tray by utilizing the function of a cable tray mechanism, is designed to allow for spacing adjustment of a pair of feeding tires, and minimizes the burden on manpower associated with the extrusion and transport of cables for laying by tightening, pulling, and pushing cables of various specifications (thickness) from both sides using a pair of feeding tires through a dual-power drive motor driven by battery power, and provides a control function via a wired or wireless method selectable depending on the environment, thereby enabling automated laying work by applying the operation of multiple traction devices through individual or integrated control. It is a well-known fact that, generally, numerous cables are routed along ceilings, floors, or walls to supply power to industrial facilities such as apartments and factories, as well as to ships and offshore structures; in particular, cable trays are used for cable laying to avoid aesthetic issues or inconvenience to passersby. Such power line installation work not only requires a large workforce but also creates extremely poor working conditions due to cramped workspaces and cable trays, resulting in very long construction periods and a high labor requirement; consequently, musculoskeletal disorders among workers are rapidly increasing. To solve this problem, a cable traction device for laying wires is used in which a cable is inserted and transported between two feeder balls that are rotated in opposite directions by an electric motor. By using this cable traction device, the worker can move the cable to the destination without exerting force, thereby improving the efficiency of the laying work and shortening the laying construction period. Although such conventional cable traction devices for laying wires have a configuration that allows for adjusting the distance between a pair of feeder balls, there are problems such as the motor's driving force not being properly transmitted or power transmission failures occurring when adjusting the distance because the driving force of the motor must be transmitted to both of the pair of feeder balls. Additionally, when two motors are used to transmit power to each pair of feeder balls, the power consumption increases further, and there is a problem of the overall weight of the cable traction device increasing. Furthermore, since these conventional cable traction devices for wire laying are configured so that both of the pair of feeder balls are driven by the motor's driving force, they have the drawback of high power consumption due to the high power requirements. In addition, most conventional cable pulling devices for laying cables simply use a fixed bracket to fasten them to the cable tray with bolts, which resulted in significant installation and removal times, leading to the drawback of a longer overall laying time. In addition, most conventional cable traction devices are designed so that the fixing bracket is mounted to the support connecting the side frames rather than to the side frame of the cable tray. Consequently, if the size of the cable traction device is larger than the distance between a pair of side frames, it cannot be installed on the corresponding cable tray, which resulted in poor compatibility. In addition, most existing cable towing devices are designed so that they cannot be stood upright and must be stored in a raised position, which has the problem of limited storage space. Although some cable towing devices are designed to be stored upright on the ground, to achieve this, the width of the main body casing is designed to be large so that the wide side of the main body casing is supported on the ground. As a result, the size of the main body casing increases, causing the overall weight of the cable towing device to rise and reducing transportability. In addition, existing cable pulling devices use heavy AC motors, and because of the use of these AC motors, a separate inverter device must be additionally provided. Therefore, when transporting the cable pulling device, the inverter device must also be transported together, which made the laying work very difficult and required a lot of time. In addition, in order to apply AC power to an AC motor, step-down transformers and inverters are essential, which leads to electric shock and reduced work efficiency. In particular, if AC power cannot be supplied depending on the site conditions, work cannot be performed, and availability is not guaranteed. Furthermore, the use of equipment based on a simple AC voltage application method inevitably leads to problems such as motor durability issues and the failure to detect accidents, which result in personnel accidents. Accordingly, there is a need to develop a cable laying traction dev
