Abstract

The utility model discloses a portable stand for unwinding wires. Three supporting legs are movably connected with a circular disc, and a bearing is arranged in the center of the circular disc; the upper part of a hanging shaft which is provided with a hook at the lower part upwardly passes through an inner hole of the bearing, and besides, a screw nut and screw threads of a screw on the hanging shaft are connected to and positioned on an inner ring of the bearing. The utility model has the advantages of simple structure, easy fabrication and installation, convenient construction and labor saving. The utility model not only can reduce the number of people for pulling wires and relieving the labor intensity of people for unwinding wires, but also can improve the work efficiency of unwinding wires. Furthermore, the utility model which is safe and reliable does not damage a wire coil. The three supporting legs can be extended and folded, so no large space can be occupied in normal times. The utility model is convenient to transport and store.

Description

Portable stand for unwinding wire

The utility model belongs to set up telephone lines a kind of pay off rack of usefulness of electric industry department frame high tension cord and postal and telecommunication entities.

Publicly-owned pay off rack is made up of two tripods by three fixed bearing legs, during unwrapping wire, earlier the center shaft two ends of drum are through in the annulus of screw mandrel bottom of two tripods, rotary screw rod is suspended between two tripods drum again, hauls the end of a thread on the drum then, the beginning unwrapping wire, make the drum running under external force, the alignment on the drum extends outward, till the electric wire on the drum is pulled.With this pay off rack unwrapping wire, the backguy personnel will just can make drum rotate with very big power, even want just stretchy of tens people, and labour intensity is big, and the drum operating speed is slow, and work is renderd a service low, and often draws bad drum, and influencing setting-out work can not carry out smoothly.

The purpose of this utility model is to provide a kind of can overcome above-mentioned shortcoming, does not take the light pay off rack that great strength turns round rapidly with regard to the stretchy drum during unwrapping wire.

The method that the utility model is finished is that the upper end of three supporting legs is installed on the same circumference of disk equably, flexibly connect with disk, make three legs can inwardly draw in arbitrarily and outwards stretch out, a bearing is installed in the through hole of disk center, there is the hanging scroll of hook the bottom upwards by the bearing center through hole, utilize nut to be connected with the screw thread on hanging scroll top again, nut contacts with bearing inner ring by pad, has promptly formed light pay off rack.Before the unwrapping wire, three supporting legs of pay off rack are outwards stretched out, the hook of hanging scroll bottom hooks lifting rope on the drum center shaft by double hook or chain and tackle block, then rotate double hook screw or pulling chain and tackle block, till unsettled between three supporting legs, the bearing that at this moment is installed in disc centre not only can bear the vertical pressure of drum up to drum, and external force is just gone slick a little, as long as a little firmly holds the end of a thread, drum turns round immediately, and setting-out work just can be finished smoothly.

The utility model has the advantages that: simple in structure, manufacturing is installed easily, and easy construction is laborsaving, not only can significantly reduce the backguy personnel, alleviates unwrapping wire personnel's labour intensity, and can improve setting-out work and render a service, and safe and reliable, does not damage drum; Three supporting legs can be stretched out gathering, do not take up an area of dish at ordinary times, make things convenient for transportation and storage.

Accompanying drawing 1 is a main structure chart of the present utility model

Most preferred embodiment of the present utility model is to fix three pairs of axle ears (6) that axis hole is arranged on the same circumference below disk (9) uniformly, three transverse axis (4) respectively with three pairs of axle ears on shaft hole sleeve use, the axis hole of three supporting legs (8) upper end utilizes transverse axis to be positioned at respectively between three pairs of axle ears, flexibly connect with disk, the shaft hole sleeve of supporting leg upper end is contained on the transverse axis that passes through an ear, and utilize the jack construction opening pin (5) of transverse axis two outer ends, after being fixed on transverse axis on the hangers, can not come off.Through hole, disk center is equipped with bearing (11), the bottom has the hanging scroll top of hook (7) upwards to pass through bearing bore, the screw on hanging scroll top is threaded with nut (2), and construction opening pin (1) on the screw mandrel on nut, nut can not be become flexible, pad below the nut (3) contacts with bearing inner ring, and stay thimble (10) is welded on the disk.Formed the alleged light pay off rack of the utility model like this.
