Abstract

The invention discloses a pay-off device. According to the technical scheme, the pay-off device comprises a rotating shaft and a shaft seat, wherein the rotating shaft is an inverted pot body; the rotating shaft and the shaft seat are connected through a tapered roller bearing; a drum brake with a bidirectional double-leading-shoe structure is mounted on the tapered roller bearing; the bottom of the brake is connected with a brake arm; an opening through which the brake arm passes and moves is formed in the shaft seat; a bottom bracket is mounted at the bottom of the shaft seat; a limiting rodis arranged on the bottom bracket and is used for limiting the brake arm in the vertical direction; the top of a brake drum is connected with a tray bracket through a bolt; and the top of the tray bracket is fixedly connected with a vertical rod. The pay-off device has the beneficial effects that sliding friction between the rotating shaft and the shaft seat is converted into rolling friction through the tapered roller bearing, so that the friction coefficient is reduced, and the pay-off device is convenient to start; and the drum brake can brake the rotating shaft in rotation, so that the hidden dangers of cable extrusion, injury to people and the like caused by over-high rotating speed of a wire coil are prevented.

Description

technical field

[0001] The invention relates to the technical field of pay-off equipment, in particular to a pay-off device. Background technique

[0002] In the construction process of power medium and low voltage transformation and communication transformation, many places need to use power cables, communication cables, and communication optical cables. Since various cables (including power cables, communication cables, and communication optical cables, etc.) are wound in the cable reel, when the cables need to be used, they need to be supported by a pay-off bracket, and the cables are dragged by an external force to be unwound. During the pay-off process, due to the friction between the pay-off bracket and the cable reel, a large external force is required to drag the cable reel to rotate, and once the cable reel rotates at a high speed, it takes a lot of external force to make it The cable reel slows down, and there are hidden dangers such as cable extrusion and injury....
