After drawing wirerope group around the traction sheave of traction machine, one end is fixedly connected with carriage, the other end and to reconnection, in order to
It avoids the problem that counterweight and carriage hypotelorism and collision occurs, under normal circumstances, a directive wheel can be also set, by leading
The position for changing the traction steel-cable of counterweight-side to wheel, so that counterweight is far from carriage.Due to counterweight weight=car weight
+ rated load * coefficient of balance, therefore when elevator no-load, the power on counterweight-side traction steel-cable is greater than cage side traction steel wire
Power on rope.Based on above structure, according to elevator Euler's formula, in actual installation, elevator no-load provided by the present invention
Static traction test detection device is mounted on the traction steel-cable of cage side, also, distance-measuring equipment 1 and traction load are
It unites ipsilateral installation.
In said structure design, distance-measuring equipment 1 preferably uses laser range finder, and distance-measuring equipment 1 is installed to traction steel
In cord and it is fixed, distance-measuring equipment 1 is using computer room roof as reference, when traction steel-cable skids and change in displacement occurs,
Distance-measuring equipment 1 can be mobile with traction steel-cable, and the distance apart from roof will change, then it can be assumed that: work as survey
When changing away from equipment 1 and roof distance, slipping phenomenon is had occurred in traction steel-cable.
Why distance-measuring equipment of the present invention 1 is preferably laser range finder, be because laser range finder have it is small and exquisite it is portable,
The advantages that range accuracy is high, laser range finder compact structure, convenient for its installation on traction steel-cable, range accuracy height can
To improve test accuracy, small skidding is avoided the occurrence of and appearance the problem of can not measure.Certainly, the present invention can also use it
The distance-measuring equipment 1 of his type, such as ultrasonic range finder etc..
In order to intuitively reflect distance measurement result, the present invention is also provided with one and connect, uses with 1 signal of distance-measuring equipment
In to ranging data carry out real-time display signal acquisition display instrument 8, signal acquisition display instrument 8 also with tension sensor 4, drag
The connection of gravitation loading device (the specially driver of the driving motor of traction force loading device) signal, connection type are wired

Rangefinder, tension sensor 4, driving motor driver can be inserted in by data line in communication interface with realize data believe
The transmission of breath, also can be wireless.Signal acquisition display instrument control circuit board has the function of signal processing etc., in feedback loop
Section introduces PID control method, it can be ensured that the stability of applied force on traction steel-cable.Specifically, signal acquisition display instrument
The signal that the detection of tension sensor 4 can be received, calculates driving of the value of thrust as feedback signal back to driving motor
Device, to control the torque of driving motor.Meanwhile signal acquisition display instrument is after receiving ranging data information, it will be able to control
The display screen of signal acquisition display instrument 8 processed shows that distance measurement result can be observed directly to ranging data.
Wherein, when promoting torque arithmetic to screw rod, it is as follows that screw rod promotes torque arithmetic derivation:
The power of boom hoist cable is provided by screw rod, and in the present invention, screw rod selects trapezoidal screw, and screw rod is machine tool
With actuated element most-often used on precision machinery, major function is to convert rotational motion to linear movement, or by torque
It is converted into axial repeated action power, while having both high-precision, invertibity and efficient feature.And trapezoidal thread root of the tooth intensity
It is high, to neutral good, it is more wear resistant compared to other screw threads, and when lead angle is less than 5 ° has self-locking function.
Shown in the torque of trapezoidal thread rotating cylinder such as formula (1):
Mq=Mt1+Mt2+Mt3 (1)
In formula: MqFor driving torque；Mt1For thread friction torque；Mt2For screw rod axial support surface moment of friction；Mt3For
Screw rod transverse bearing moment of friction.
In design, thrust bearing is added on the supporting surface (structure of mounting base) being supported to trapezoidal thread rotating cylinder
With deep groove ball bearing, by screw rod axial support surface moment of friction Mt2, screw rod transverse bearing moment of friction Mt3Influence to system
Very little is dropped to, is ignored herein, therefore MqCalculation formula can simplify are as follows:
Mq≈Mt1 (2)
d2=d-0.5P (4)
In formula: d2For pitch diameter of external thread；F is the axial load of worm drive；λ is lead angle；ρ ' is equivalent friction
Angle；D is external screw thread major diameter (nominal diameter)；P is screw pitch；S is lead；F is friction factor；α is groove profile angle.
T-type screw thread specification of the present invention is as follows: d=16mm, P=2mm, s=2mm, f=0.06, α=pi/2,
After the parameter is substituted into formula (2)~(6), the relationship of lifting force and torque can be obtained.
