Description
Technical field
The utility model is a kind of proving installation of life-float, particularly is that the drag-line that is used for life-float examination and test of products project starts a kind of tension measuring device of inflating tensile test.
Background technology
Air inflation raft, have easy to use, inflation rapidly, the relief number is more and advantage such as good heat insulating, in case run into maritime affairs, just may in time be succoured after using air inflation raft, be that in a single day comparatively desirable lifesaving equipment behind the casualty takes place boats and ships.China waters can both be used at boats and ships, tourism, operation at sea more greatly, just has been equipped with air inflation raft on the fishing boat, can succour the life that surpasses 200 fishermen every year, and this has demonstrated fully the importance of this production.Life-float cloth quality is directly connected to the personnel's that rescued life security, so life-float cloth air-tightness is an important indicator of judging life-float cloth quality.
Life-float is a kind of lifesaving appliance that the boats and ships operation at sea must be equipped with, and is the most direct after overwater accident takes place, the instrument of saving oneself the most rapidly.At present, all use air inflation raft both at home and abroad, only need pulling to start drag-line, just can be the life-float carcass and inflate, rescue effect in the performance water.Along with China's rapid economy development, the demand of domestic life jacket constantly rises, and many in recent years enterprises have pushed product to international market.But the data of spot-check in recent years with consignment according to my center show, domestic life-float starts the pulling force ubiquity, and to start pulling force too high, can not satisfy existing domestic and international standard.Trace it to its cause: be life-float product sole mass problem on the one hand; Manual operation factor when being detection on the other hand, pulling start the power thrusts of drag-line, the size of exerting oneself etc. all can influence test result.
In order to promote China's life-float detection level, for the user holds gate of the quality monitoring, for manufacturing enterprise is responsible for, must provide a kind of life-float to start pull force tester, eliminate the mode that in the past adopts hand-held tautness meter to measure, with science more, more reasonable manner detects, and reduces the influence of human factor to testing result, improves the accuracy of Monitoring Data.
Summary of the invention
The purpose of this utility model intends providing a kind of life-float to start pull force tester, and eliminating and reducing human factor influences, and improves the accuracy of Monitoring Data and convenience, the practicality of test.The purpose of this utility model so realizes.
A kind of air inflation raft drag-line device for measuring force is characterized in that:
A rotating shaft is set being the upper rack of being inverted the T word, is positioned at the position configuration runner of frame vertical centre, the outer end configuration turning handle of rotating shaft in rotating shaft;
On runner, be nested with lifting rope, one end of lifting rope hangs the gravitational equilibrium piece, the strip pulling force transverse arm that the fixedly connected level of the other end of lifting rope is horizontal, the two ends of pulling force transverse arm are provided with two sprocket wheels, be nested with a chain around two sprocket wheels, fixing pulling force seat on chain is provided with pull hook through tautness meter on the pulling force seat, and pull hook and tested life-float G drag-line are interlockingly connected;
The end that pulling force transverse arm and life-float G offset is provided with a pair of arranged side by side, vertical rubber pin;
With the sprocket coaxiality on the pulling force transverse arm other end, fixing rotation pulling force handle.
Further, the bottom of described frame is provided with wheel.
Further, the mounting hole of described rotating shaft on the upper rack rectangular frame is configured in upper rack;
The outer end of rotating shaft disposes a set lever with thread forms between turning handle and rectangular frame sidewall.
Further, on described pulling force seat, cover the retaining over cap through tautness meter top.
Adopt the technical program, mainly contain following three actions:
1. highly regulate up and down:
According to detection life-float valve body size, can make the pulling force transverse arm do vertical movement up and down by regulating turning handle, and drive a pulling force seat and a gravitational equilibrium piece relatively moves, thereby can adjust the height of pulling force seat by the testing staff easily, easily, make that the startup drag-line is stressed at horizontal level.
2. parallel pulling mechanism:
In order to obtain science, to start pulling force data accurately, two vertical rubber pins that utilize pulling force transverse arm front end to be equipped with, two bars are close to raft body under the effect of pulling force, guarantee that pulling force and startup drag-line are on the same horizontal line and vertical with valve body.
3. tensile machine
A pulling force handwheel is arranged,, tautness meter is housed on the chain by chain transmission.During detection; pass through operating personnel; the uniform rotation rotating disk; under the draw of chain; tautness meter can move back and forth on the chute of pulling force transverse arm; wherein to be inserted in the tautness meter pedestal be on the pulling force seat to tautness meter, and prevent that by the retaining over cap tautness meter from coming off, and accurately measured and record starts pulling force by tautness meter.
Advantage of the present utility model and beneficial effect provide a kind of life-float to start pull force tester, eliminate and the human factor influence of minimizing in test, have improved the accuracy of Monitoring Data and convenience, the practicality of test.
