Handgrip, motor, winding pin, wheel, pulley A, pulley B, pulley C, tensiometer dial plate,
Steel wire rope, movable handgrip, it is characterised in that:The top of casing is provided with operating platform,
The upper end of operating platform is provided with detachable protective cover, is provided with the right-hand member of operating platform solid
Determine handgrip, the inner top side of casing is provided with motor, be provided with the rotary shaft of motor and twine
Terminal, the lower end of casing four, corner location is provided with wheel, is provided with the inside of casing
Pulley A, pulley B, pulley C, pulley A pulley A and is twined also in the right-hand member of box inside
Terminal is mutually correspondingly arranged up and down, pulley B, pulley C box inside left end, pulley B,
Pulley C is mutually to be correspondingly arranged up and down；The tensiometer dial plate is arranged under box inside
End；One end of the steel wire rope is fixed on winding pin, and passes sequentially through pulley A, tensiometer
Dial plate, pulley C, pulley B and movable handgrip are fixedly connected.
Further, the motor is connected with attaching plug by controller wire.
The device critical piece and operation principle are that motor positive and inverse moves the receipts for realizing steel wire rope
Put, this has a little liberated the artificial force to steel wire rope；Controller can make motor carry out rotating；
The draw-bar donamometer disc gage that Jing was verified is connected to two sections of steel wire rope, can accurately know pulling force
Size；Detachable protective cover is carrying out being played a protective role when belt force is tested, and prevents
Breaking because safety belt is unqualified causes testing crew to come to harm.
During work, safety belt is buckled, one end is enclosed within movable handgrip, the other end is enclosed within solid
Determine on handgrip, then by detachable protective cover install on the operational platform, rear motor connect electricity
Source, by the control of controller, motor is rotated forward, when draw-bar donamometer disc gage reaches or connect depending on number
When closely requiring, in slow control controller so as to which dynamics size reaches regulation requirement.Motor revolves
Turn to pull steel wire rope, so as to exert a force to safety belt, this is safety belt breakdown test test safety belt
Whether qualified steps necessary.If the quiet drawing of test of standard can be born within the time of regulation
Power, then test item is qualified, and the contrary test item if it can not bear (earn disconnected or deform) does not conform to
Lattice.After off-test, then motor reversal is made by controller, steel wire rope looseness, can by by
Test product safety belt is removed.
Test item includes back belt, safety rope and the enclosing belt of full body harness.
The invention has the beneficial effects as follows:Hand labor, simple structure are liberated.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
According to Fig. 1, a kind of full body harness breakdown test device of the invention, including case
Body 1, operating platform 2, detachable protective cover 3, fixed handgrip 4, motor 5, winding pin
6th, wheel 7, pulley A8, pulley B9, pulley C10, tensiometer dial plate 11, steel wire rope 12,
Movable handgrip 13, it is characterised in that:The top of casing 1 is provided with operating platform 2, in behaviour
The upper end for making platform 2 is provided with detachable protective cover 3, arranges in the right-hand member of operating platform 2
There is fixed handgrip 4, the inner top side of casing 1 is provided with motor 5, in the rotation of motor 5
Winding pin 6 is provided with axle, corner location is provided with wheel 7 the lower end of casing 1 four,
The inner side of casing 1 is provided with pulley A8, pulley B9, pulley C10, pulley A8 is also in case
The right-hand member of the inner side of body 1, pulley A8 and winding pin are mutually correspondingly arranged about 6, pulley B9,
In the left end of the inner side of casing 1, pulley B9, pulley C10 are mutually to correspond to up and down to pulley C10
Arrange；The tensiometer dial plate 11 is arranged on the lower end of the inner side of casing 1；The steel wire rope 12
