Lifting type wire unwinding device with drum type foot brake

Abstract

The invention provides a lifting type wire unwinding device with a drum type foot brake. Through the small-size fixed rolling wheel structures, the space is greatly saved, and the lifting type wire unwinding device is light in weight, easy to carry, assemble and disassemble and convenient to transport and store. Through locking pins, a cable reel can be placed on the locked rolling wheels for usein the transportation process. Disks of the cable reel are supported respectively so that the cable reel cannot be abraded in the unwinding process without adjustment, the working efficiency is high,and the cable reel is free of restriction of road traffic police. The cable reel can be placed more stably and reliably by adjusting the distance between the two rolling wheels and is more convenientand flexible to adjust and use. The drum type foot brake device is arranged and suede for controlling rotation of the cable reel. The lifting type wire unwinding device with the drum type foot brake can guarantee that a cable on the cable reel is unwound orderly during actual construction according to the practical situation and is faster and more convenient to use. The lifting type wire unwindingdevice is simple in structure, fast and convenient to install and operate, reusable, economical, practical, reasonable in design, compact in structure and suitable for extensive popularization.

Description

technical field [0001] The invention relates to the technical field of electric power system auxiliary equipment, in particular to a lift-type wire spreading device with a drum-type foot brake. Background technique [0002] Conventional wire pay-off brackets and wire reel trailers have the following problems: 1. The pay-off rack is large in size and weight, takes up transportation space, and requires laborious loading and unloading; 2. A large iron bar is required to support the wire reel, which is very heavy and requires two people to carry it Carrying and moving consumes a lot of manpower and increases the transportation volume; 3. During the unwinding process, it is easy to cause the reel to rub against the pay-off bracket, which needs to be adjusted to affect work efficiency; Vehicles and artillery vehicles need to have brakes and complete lights; 5. Due to the high center of gravity, the bracket area is small, unstable, and can be tilted and hurt people; 6. The improper...

[0002] Conventional wire pay-off brackets and wire reel trailers have the following problems: 1. The pay-off rack is large in size and weight, takes up transportation space, and requires laborious loading and unloading; 2. A large iron bar is required to support the wire reel, which is very heavy and requires two people to carry it Carrying and moving consumes a lot of manpower and increases the transportation volume; 3. During the unwinding process, it is easy to cause the reel to rub against the pay-off bracket, which needs to be adjusted to affect work efficiency; Vehicles and artillery vehicles need to have brakes and complete lights; 5. Due to the high center of gravity, the bracket area is small, unstable, and can be tilted and hurt people; 6. The improper use of the shaft bracket of the reel bracket causes personal injury and death accidents; 7. Assembling the pay-off frame requires many people to complete, and the labor intensity is high; 8. There is no special equipment to control the pay-off speed during display, which is prone to safety accidents, so it is necessary to develop a pay-off device
