Description
Technical field
The utility model relates to special equipment detection fields, in particular to a kind of traction elevator velocity measuring device.
Background technique
When carrying out tail guarantor and periodic detection to elevator at present, elevator speed detection is all referred to, to improve the accurate of detection
Degree, general requirement cannot directly take the speed signal on elevator-mainboard, need to use the third party device independently of elevator, measure elevator
Real time execution speed, to achieve the purpose that comparison and calibration.However, existing several elevator speed measurement methods exist it is a little
Disadvantage:
1, laser velocimeter method, this method use the principle of laser velocimeter, inject beam of laser to sedan-chair in elevator top
Compartment top calculates elevator speed by the laser reflection time.This method need to find one for carriage in elevator top
Duct, it is desirable that car top is smooth with vertical reflection laser, and it is close that right Today, most elevator top considers that safety factor has been done
Envelope processing, and there are the equipment such as air-conditioning, fan in bridge compartment top portion more, the use of the program has certain limitation, and high-precision laser
Speed measuring equipment price is generally higher, and laser velocimetry fails to be used widely in elevator speed-measuring field.
2, power wheel speed indirect measurement method, this method are passed through by installing magnetic sensor additional on elevator power wheel
The number of teeth converses elevator linear running speed on unit time internally-powered wheel.This method needs to dismantle elevator power wheel shield,
Install sensor additional on rotating machinery, not only installation is complicated, but also there are sensors to install unstable installation problems.
3, hoist ropes movement velocity measures, the hoist ropes movement velocity and elevator motion length velocity relation Cheng Gu of traction elevator
Electricity is calculated according to the traction ratio of elevator by the movement velocity of directly measurement hoist ropes in certainty ratio -- traction ratio, this method
The terraced speed of service.Program install convenient, applicability are wide, but it is most due to cannot be in close contact between hoist ropes and tachymeter and
There are slippage problems.It is existing frequently-used for hand-held speed instrument to solve slippage problems, it needs manually by equipment close to elevator traction
Rope drives the encoder connecting with fifth wheel to rotate, so that traction-type be calculated by the frictional force of hoist ropes and fifth wheel
Elevator speed.This method needs operator close to the elevator host of movement, and safety is poor, and artificial hold has the shakiness that tests the speed again
Fixed drawback.
Summary of the invention
The purpose of this utility model, which seeks to provide one kind, is easily installed fixation, and can directly measure elevator speed
