Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
With reference to Fig. 1, the dynamic impulsion strength test fixture of a kind of chain provided by the invention, rope, comprise frame 100, be located at the fixed bit 200 that frame 100 tops are connected with chain to be tested, rope one end, be positioned at fixed bit 200 belows be connected with chain to be tested, the rope other end and can increase, the bearing component 300 of loss of weight amount, and be located on the frame 100 and can drive bearing component 300 and move up and down and make its moment to fall and treat the hoisting gear 400 that test chain, rope produce impact tension.Among the present invention, chain to be tested, rope one end are fixed on the fixed bit 200, one end is connected with bearing component 300, also moment fell after bearing component 300 moved up under hoisting gear 400 drives, the bearing component 300 that falls is treated the test chain, rope produces impact tension, thus the dynamic impulsion intensity that can test chain, rope; And for different chains, rope, can increase, subtract the weight of bearing component 300, thus adopt this test fixture, simple to operate, reliable, reduce working strength, increase work efficiency.
The crossbeam 320 that in the present embodiment, bearing component 300 comprises a hook 310 that vertically arranges, worn by hook 310 middle part levels and the counterweight 330 of some Different Weight.Particularly, hook 310 two butt hooks 312 that comprise a body 311 and be located at respectively body 311 top and bottoms, crossbeam 320 is by passing in the body 311, the butt hook 312 that is positioned at body 311 tops is used for being connected with the other end of chain to be tested, rope, and the butt hook 312 that is positioned at body 311 bottoms is used for hanging counterweight 330.
Further, frame 100 comprises that the inboard of two columns, 120, two columns 120 of horizontal top 110 and roof supporting vertically arranges respectively a slide bar 500; The two ends of crossbeam 320 are sheathed on respectively on the slide bar 500 and can be along slide bar 500 upper and lower slips, like this, bearing component 300 move or folding process in, crossbeam 320 also plays position-limiting action, avoids bearing component 300 to rock.
Further, also be provided with locking mechanism 600 between the two ends of crossbeam 320 and the slide bar 500.Particularly, locking mechanism 600 comprises the spacing hole (not shown) of being located on the slide bar 500 and is located at crossbeam 320 two ends and can axially be inserted in the interior locking pin 610 of spacing hole.Preferably, locking pin 610 is a spring pin.By locking mechanism 600 is set, to realize the secondary of bearing component 300 is fixed, bearing component 300 falls when avoiding electromagnet 440 for absorption crossbeam 320 to lose efficacy, thereby also guarantees the security of test.
Refer again to Fig. 1, in the present embodiment, hoisting gear 400 is two groups, is located at respectively the both sides of fixed bit 200.When chain to be tested, rope want the load of load-bearing heavier, can promote by two groups of hoisting gears 400, efficient is high, and two groups of hoisting gears 400 lay respectively at fixed bit 200 both sides, namely be positioned at the both sides of chain to be tested, rope, guaranteed the stationarity that promotes; When chain to be tested, when the rope heavy burden is lighter, can only adopt one group of hoisting gear 400 to get final product, selection mode is flexible like this, also realizes the rational and efficient use of anchor clamps, does not cause waste.
Particularly, hoisting gear 400 comprises the motor 410 of being located at frame 100 tops, be located at drum 420, an end on the motor output shaft 411 is wound in the wire rope 430 on the drum 420 and is fixed in electromagnet 440 on the other end of wire rope 430 and the control circuit (not shown) of control motor 410 forward and backwards, and electromagnet 440 is adsorbed on the crossbeam 320.In the present embodiment, by control circuit control motor 410 forward or reverse, motor 410 is motor output shaft 411 forward or reverse when forward or reverse, drive drum 420 forward or reverse, thereby the lay winding wire ropes that upwards stretches 430 or loosen wire rope 430 downwards, electromagnet 440 is adsorbed on the crossbeam 320 in this process, thereby also correspondingly drives bearing component 300 and move up or down.
Further, in the present embodiment, control circuit carries out open and close control by telepilot (not shown) or line control machine (not shown).Like this, operating personnel can away from test fixture, guarantee tester's security when carrying out test job.
Further, in the present embodiment, but the inboard of column 120 also is provided with and is connected with control circuit and the travel switch 700 of perception crossbeam 320 sliding positions.Sense crossbeam 320 when hoisting gear 400 drives lower slider to the precalculated position when travel switch 700, control circuit is opened circuit, this moment, motor 410 stopped moving turning, thereby stopped the lifting to bearing component 300.
Further, with reference to Fig. 1, the bottom of two columns 120 also is provided with a base plate 130, and base plate 130 is provided with and can holds the drop cavity 131 of rear placement of counterweight 330.Like this, counterweight 330 drops and is placed in the cavity 131, effectively avoids its ejection to pound and hurts sb.'s feelings, thereby play effective safety protection function.
With reference to Fig. 2, be the counterweight structural representation of a kind of 10kg in the present embodiment, have a butt hook 331 on this counterweight 330.With reference to Fig. 3, be the counterweight structural representation of a kind of 20kg in the present embodiment, have two butt hooks 331 on this counterweight 330, the counterweight of convenient a plurality of Different Weight makes up the realization load-bearing, can carry out strength test to different chains, rope like this.In the present embodiment, counterweight 330 has the equal-specifications such as 5kg, 10kg, 15kg, 20kg, can select arbitrarily during actual the use.
In the present embodiment, the principle of work of test fixture is: by control circuit the electromagnet 440 in two groups of hoisting gears 400 is switched on, electromagnet 440 produces magnetic force crossbeam 320 is held, the recycling control circuit is controlled motor 410 forwards pulling wire rope 430 with crossbeam 320 and is linked up with 310 pull-ups, when travel switch 700 induction crossbeams 320 arrive predetermined altitude, the control motor is opened circuit, motor shuts down, thereby stop the lifting to crossbeam 320, at this moment, locking pin 610 is inserted in the spacing holes, crossbeam 320 is fixed on the slide bar 500, realize crossbeam 320 and link up with 310 secondary and fix.One end of chain to be tested, rope is fixed on the fixed bit 200, the other end is fixed on the butt hook 311 at hook 310 tops, then increase counterweight and bear a heavy burden according to chain to be tested, the required weight that bears of rope, when increasing to approrpiate wts, extract locking pin 610 out, then two electromagnet 440 are cut off the power supply simultaneously, lose magnetic force after electromagnet 440 outages, bearing component 300 freely fell along 500 moments of slide bar, treat test chain or wire rope and produce instant impact, thereby reach the purpose of testing chain, line strength.In the above-mentioned test process, directly utilize motor to mention and put down bearing component, alleviate operating personnel's workload, and whole operating process is simple and convenient, safe and reliable.
Below only be preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
