Description

The flexible test device that is used for cable

The utility model relates to a kind of flexible test device that is used for cable.

Known to cable, in a single day particularly cross-linking radiation polyolefin insulation used for rolling stock cable is not all carried out flexibility test,, will take place cable is installed inconvenience when the situation that cable flexible force difference occurs, and make cable cause damage easily, influence the normal use of cable.Therefore be very important for the flexible force of testing cable at present.

The purpose of this utility model is to fill up known nothing to be had pair blank of cable flexible force test and a kind of flexible test device that is used for cable that has the cable performance control ability and the authentic data foundation is provided for the raising of cable quality is provided.

The purpose of this utility model is achieved in that

The track plate is housed on plane on the casing, the rear and front end of track plate is separately installed with riser, on the track plate, have two parallel grooves, by trip bolt the slide plate that installs with the track plate is installed in the groove, on this slide plate, guide rail is housed, the riser that has screw is installed in rear end at slide plate, slide is installed on the guide rail, equal setting pressure sensor on two planes of symmetry of slide, the adjustment screw of adjusting pressure transducer also is housed on guide rail, on the guide rail of pressure transducer front end ball is housed, on ball, place bearing seat, bearing is installed on bearing seat, dynamometer link is housed in the bearing, screw by the riser on the slide plate also is coated with the leading screw that is packed on the track plate, one end of this leading screw passes on the track plate riser that an end is wherein installed, on its termination, be equipped with handwheel, the riser that the track plate other end is installed also is coated with leading screw, the outer end of its leading screw also is equipped with handwheel, the other end at this leading screw is installed slide block, setting pressure sensor on this slide block, on plane on the casing of track plate both sides, also be fixed with supporting seat respectively, the reel that has rotating shaft is installed in upper end at supporting seat, end at reel is shaped on the fixed cable hole, end in the rotating shaft on the reel is even adorned the speed reduction unit that is installed on the casing by shaft coupling, its input shaft of speed reducer also connects by the shaft coupling that has grating reductor is housed, reductor also is installed in casing, and motor also is installed on reductor, on the plane micro photo electric switch is being housed on the casing of grating bottom.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

Be described in further detail below in conjunction with embodiment of the present utility model:

See figures.1.and.2, track plate 32 is housed on plane on the casing 1, the rear and front end of track plate is installed riser 2 and riser 16 respectively, wherein riser 2 installs with casing, on the track plate, have two parallel grooves 24, slide plate 18 is housed in groove, and slide plate installs by trip bolt 17 and track plate.Guide rail 31 also is housed on slide plate 18, and the riser 35 that has screw is installed in the rear end of slide plate, and slide 33 is installed on guide rail, on two planes of symmetry of slide pressure transducer 20 is housed all, is equipped with adjustment screw 19 for adjusting this pressure transducer on guide rail.On the guide rail of the front end of this pressure transducer, ball 34 is housed, places bearing seat 21 on the ball, by bearing seat thereon, dynamometer link 23 is housed in bearing bearing 22 dresses.That screw by the riser on the slide plate 18 35 is coated with adjusting slider and be packed in leading screw 27 on the track plate, an end of leading screw is equipped with handwheel 15 after passing riser 16.Equally also be coated with leading screw 6 in riser 2, in the outer end of leading screw 6 handwheel 3 adorned thereon, the other end of this leading screw also is equipped with slide block 26, and pressure transducer 5 is housed on slide block, and this pressure transducer is installed on the slide block 26 by screw 4.On plane on the casing of track plate both sides, also be fixed with supporting seat 7 in addition respectively, the reel 8 that has rotating shaft 9 is installed in upper end at supporting seat, end at reel is shaped on fixed cable hole 30, end in rotating shaft on the reel connects dress by shaft coupling 28 and the speed reduction unit 10 that is packed on the casing, input shaft 11 on this speed reduction unit links to each other with the reductor 13 that also is packed on the casing by the shaft coupling 29 that has grating 12, and motor 14 also is installed on reductor.On the plane micro photo electric switch 25 is being housed on the casing of grating bottom.

Operating principle of the present utility model is:

Rotate handwheel 3, regulate pressure transducer 5, pressure transducer 5 is acted on the dynamometer link 23, reach the purpose that pressure transducer 5 is checked pressure transducers 20, accurate after, riser 2, handwheel 3, screw 4, pressure transducer 5 and slide block 26 are removed.Be wrapped in tested cable on the reel 8 by fixed cable hole 30 this moment again, regulate leading screw 27 simultaneously, promoting slide plate 18 makes the dynamometer link 23 and the down suction of reel 8 equal the diameter and the fine setting adjustment screw 19 of tested cable, make dynamometer link 23 and reel 8 keeping parallelisms, tested cable freely hangs down, by trip bolt 17 track plate 32 and slide plate are fixed again, starter motor 14, drive reductor 13, by the input shaft 11 on the shaft coupling 29 drive speed reduction units 10 that have grating 12, drive shaft coupling 28 by speed reduction unit 10 again, shaft coupling 28 drives 8 pairs of tested cables of reel again and carries out flexibility test, draws the flexible data of relevant tested cable at last by pressure transducer 20 process computer system programmed control.

Advantage and the good effect that the utlity model has are: the utility model passes through department of computer science System program control through data collecting system, makes the flexible force certainty of measurement height of tested cable, And data are accurate, namely use the utility model can strengthen the control ability of cable performance, for The raising of cable quality provides the authentic data foundation. The utlity model has rational in infrastructure, practicality The property strong advantage, the utility model also has handled easily and operates steadily and use reliable in addition Characteristics.
