Description
Technical field
The utility model is related to pulley, specifically a kind of device for preventing well logging top sheave interior media from jumping out.
Background technology
When progress cable, steel wire remove instrument well logging, top sheave connection is arranged at the top of lubricator.Lifting,
Double swerve is very big when holding up lubricator, and cable, steel wire are easy to jump out out of top sheave groove, it is necessary to which 1-2 people tenses cable, steel
Silk, prevents cable, steel wire from jumping out as far as possible, and squeezes wound and break.Generation instrument falls well, casualty accident, there is hidden danger, and
Labor strength is big.Therefore, we devise a kind of convenient preventing jump type well logging top sheave.It is simple and practical, reduce constructor
Member, alleviate labor intensity, it is to avoid cable, wire out groove, break cable or steel wire, occur instrument and the accident such as fall well, hurt sb.'s feelings.
Utility model content
The purpose of this utility model is to provide a kind of device for preventing well logging top sheave interior media from jumping out, in lifting
When, cable wire is remained in top sheave groove without job-hoping.Avoid that cable, wire out groove are broken, instrument falls well thing
Therefore.
In order to reach above-mentioned purpose, the utility model employs following technical scheme, and one kind is prevented inside well logging top sheave
The device that medium is jumped out, including U-shaped support, the U-shaped support include front frame body and back frame body, the front frame body and after-frame
Body is located at pulley front and rear sides and is fixed on the pulley spindle of pulley respectively, in addition to preceding Y-shaped support, rear Y-shaped support, pressure
Post, the preceding Y-shaped support is connected to front frame body upper end, and the rear Y-shaped support is connected to back frame body upper end and and after-frame
Body is integral type structure, and compression leg is connected between the preceding Y-shaped pedestal upper end and rear Y-shaped pedestal upper end.
The compression leg front end is welded and fixed with preceding Y-shaped support, and compression leg rear end is then overlapped on rear Y-shaped pedestal upper end and opened up
Arc groove in.
Copper pipe is cased with outside the compression leg.
The preceding Y-shaped support lower semisection opens up chute hole, and the front frame body upper semisection welds positioning cylinder, positioning cylinder
Insert in chute hole.
Threaded circular hole is opened up on the front frame body, with band handle screw bolt passes chute hole, threaded circular hole by preceding Y
Font support is fixed on front frame body.
Compared to prior art, the utility model has the advantages that：
The top sheave, design is simple, and operation is flexible, safe and reliable, usually lifts by crane lubricator；It is tight when loose during cable wire；
It is very serious that top sheave rocks；Cable or steel wire are easy to jump out from race, it is necessary to which 1-2 people's righting is tensed；And this top sheave
Cylinder position of the pedestal upper end with copper pipe compresses pulley and combined closely with pulley, without space, is enclosed on the copper outside cylinder
Pipe can together be rotated with top sheave, because copper pipe material is softer than steel wire, without being damaged to cable or steel wire.Due to being tight
Close combination, in lifting, cable wire is remained in top sheave groove without job-hoping.Cable, wire out groove is avoided to draw
Disconnected, instrument falls well accident；Reduce staff, to alleviate labor intensity safe and reliable, easy to use.
