Lifting type wire unwinding device with lever hand brake

Abstract

The invention provides a lifting type wire unwinding device with a lever hand brake. A fixed type roller structure small in size is adopted, space is greatly saved, the weight is small, carrying, loading and unloading are easy, and transportation and storage management are facilitated. A locking pin is arranged, and therefore a wire coil is placed on positioned and locked rollers in the transporting process and can be used more conveniently and quickly; discs of the wire coil are supported independently, wire coil friction in the unwinding process is avoided, adjustment is not needed, the working efficiency is high, and limitation to road traffic polices is avoided; the distance between the two rollers is adjusted, the wire coil can be placed more stably and reliably, and adjustment and use are more convenient and flexible; the lever hand brake device is arranged, the rotating speed of the wire coil is controlled, and orderly wire coil unwinding according to actual condition in actualconstruction can be guaranteed; and the lifting type wire unwinding device is simple in structure, convenient and quick to install and operate, recyclable, economical, practical, reasonable in design,compact in structure and suitable for wide popularization.

Description

Technical field [0001] The invention relates to the technical field of auxiliary equipment for power systems, and in particular to a lift-type wire extension device with a lever hand brake. Background technique [0002] Conventional wire pay-off brackets and spool trays have the following problems: 1. The pay-off racks are large in size and weight, occupying transportation space and laborious loading and unloading; 2. Large iron bars are required to support the spools, which are extremely heavy and require two people to lift them. Handling and moving consumes a lot of manpower and increases the transportation volume; 3. It is easy to cause the spool to rub against the pay-off bracket during the laying-out process, which needs to be adjusted, which affects the work efficiency; 4. When the spool is transported by a gun truck, the road traffic police checks the buckle Cars and artillery carts need to have brakes and complete lighting; 5. Due to the high center of gravity, the bracke...

Problems solved by technology

[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
