Embodiment
Be described further according to specific embodiment below.
As shown in Figure 1, (1) support 1 and suspension platform 2, support 1 adopts gantry frame structure form.Utilize square steel to be welded, there is simple for structure, that stability is high feature.Suspension platform 2 is for the load that applies in bearing test process and balancing weight 8.
(2) haulage gear: comprise main rope 14, secondary rope 15, pulling rope 16, electric hoist 9, blind rope chopper 5, one end of main rope 14 connects blind rope chopper 5, and through the swing arm of safety lock 4 to be measured, the other end is connected with electric hoist.Main rope 14 is driven to control the lifting of suspension platform 2 by electric hoist 9 during system works.Secondary rope 15 is by safety lock 7 to be measured, when motor 12 works, namely blind rope chopper 5 is pulled to make it thread off when suspension platform 2 freely falling body is to certain distance, secondary rope 15 is lockable, and utilizes displacement sensor for pull rope 11 distance measured now to be exactly the lock rope distance of safety lock 7 to be measured when simulating suspension platform 2 free falling.
(3) bindiny mechanism: utilize blind rope chopper 5 to connect main rope 14, utilizes motor 12 to control to clamp the duty of blind rope chopper 5 simultaneously.
(4) counterweight: counterweight adopts combined counterbalance block 8 corresponding to the trial load of standard-required to realize.
(5) buffer gear: adopt elastic buffering mechanism 17, be placed on the below of balancing weight 8, when safety lock 7 disabler to be measured, play buffer action.
(6) measuring mechanism: be divided into hardware and software two parts.
Hardware components: be divided into the displacement transducer in angular transducer 6 and rope sensor 11.
A, measurement of angle: the angle of swing arm when utilizing obliquity sensor 6 to measure safety lock 7 locked main rope 14 to be measured, obliquity sensor 6 is arranged on suspension platform, the angle of inclination of real-time measurement suspension platform 2, utilize traction rope 16 to hold suspension platform 2 side, electric hoist 9 puts down main rope gradually, suspension platform 2 opposite side declines, cause inclination, when angle reaches safety lock 7 locked angle to be measured, secondary rope 15 is locked, suspension platform 2 cannot decline, and utilizes obliquity sensor 6 to measure angle now.
B, range observation: utilize the displacement sensor in rope sensor 11 to lock rope Distance geometry and leave standstill slippage and lock rope speed.Rope sensor 11 is arranged on the entablature of support 1, and main rope 14 one end is fixed on suspension platform 2.When blind rope chopper 5 depart from main rope 14, suspension platform 2 fall time, secondary rope 15 is pinned by safety lock 7 to be measured, utilizes the distance now of the displacement sensor in rope sensor 11 to be exactly the lock rope distance of suspension platform 2 free falling.Utilize this result can calculate lock rope speed by formula, when pinning secondary rope 15, static placement suspension platform 2, utilize the displacement transducer in rope sensor 11 can measure standing sliding displacement, computing machine 18 picks up displacement transducer distance signal, obliquity sensor 6 angle signal in rope sensor 11, carries out analyzing and processing to the signal of sensor.
