Technical field
The utility model relates to a kind of detection device of measurement instrument more particularly to a kind of taximeter detection dresses
It sets.
Background technique
Taximeter is to show the valuation finally charged then in conjunction with unit price by measuring taxi mileage travelled
Device, accuracy directly affect the vital interests of consumer.Detection device currently used for taximeter is usually by can
Part is handled with the drum apparatus of mileages rotation, the sensor of detection roller rotating cycle and computerized informations such as taxi driving wheels
It constituting, and drum apparatus generallys use spaced two rollers, taxi driving wheel is located at two rollers top when detection, and three
Person is tangent, acquire taxi driving wheel mileage travelled, but the tire of its driving wheel for having ignored taxi be it is flexible,
Be it is deformable, there are bigger differences for the denaturation after the stress of wheel and normally travel in the detection process, therefore influence inspection
Survey result.In addition, this kind of roller general diameter is smaller due to being designed using twin-roll, thus drum shaft and its rotating connector it
Between the factors such as gap, vibration and accuracy to size bring biggish error, or even phenomena such as dally, also influence
The accuracy of meter of hiring a car detection.
Utility model content
The utility model is intended to for deficiency present in background technique, and a kind of taximeter provided detects dress
It sets.

As the preferred of the utility model, it is equipped with longitudinal open slot on the isosceles trapezoid monitor station at rotary roller both ends,
The shaft lower part at rotary roller both ends is respectively mounted spring.
A kind of taximeter detection device of the utility model, preferably simulates taxi in the detection process
The stress condition of driving wheel when normally travel reduces driving wheel and deforms and the influence to testing result；Since it uses double roller
Positioning support, then by individually rotary roller is abutted with driving wheel in the middle part of double roller, rotary roller periphery be enclosed with rubber sleeve and
Frictional force between driving wheel is larger, will not improve the precision of detection data there is a situation where generation of skidding；In detection process
In, PLC control device can control brake gear, easy to operate.
Detailed description of the invention
Fig. 1 is the longitudinal sectional view of the utility model；
Fig. 2 is the top view of the utility model.
Specific embodiment
With reference to the accompanying drawing 1 and attached drawing 2 to a kind of taximeter detection device of the utility model, make furtherly
It is bright.
Embodiment 1
A kind of taximeter detection device of the utility model, including isosceles trapezoid monitor station 1, isosceles trapezoid inspection
1 front of scaffold tower is equipped with the transverse passageway 2 of upper opening, is successively arranged from front to back in transverse passageway 2 and is installed with the first load bearing roller
3, rotary roller 4 and the second load bearing roller 5, one end of 4 roll shaft of rotary roller are placed in the outer end of isosceles trapezoid monitor station 1 and are installed with disk
6, Hall sensor 7 is installed on the isosceles trapezoid monitor station 1 of the inside of disk 6, Hall sensor 7 and is fixed on isosceles trapezoid inspection
One end of 8 connection of PLC control device on scaffold tower 1,5 roll shaft of the second load bearing roller is placed in the outer end of isosceles trapezoid monitor station 1
Gear 9 is installed, gear 9 is engaged with the gear on the brake gear 10 for being fixed on 1 outside of isosceles trapezoid monitor station.
Embodiment 2
A kind of taximeter detection device of the utility model, including isosceles trapezoid monitor station 1, isosceles trapezoid inspection
1 front of scaffold tower is equipped with the transverse passageway 2 of upper opening, is successively arranged from front to back in transverse passageway 2 and is installed with the first load bearing roller
3, rotary roller 4 and the second load bearing roller 5, one end of 4 roll shaft of rotary roller are placed in the outer end of 1 side of isosceles trapezoid monitor station and are installed with
Disk 6, is installed with Hall sensor 7 on the isosceles trapezoid monitor station 1 of the inside of disk 6, Hall sensor 7 and is fixed on isosceles ladder
8 connection of PLC control device on shape monitor station 1, it is another that one end of 5 roll shaft of the second load bearing roller is placed in isosceles trapezoid monitor station 1
The outer end of side is simultaneously installed with gear 9, gear 9 and the gear on the brake gear 10 for being fixed on 1 outside of isosceles trapezoid monitor station
Engagement.4 periphery of rotary roller is enclosed with rubber layer 11, when the driving wheel traveling of taxi is parked in the first load bearing roller 3 and the
When on two load bearing rollers 5, the tire of driving wheel can with rotary roller 4 is tangent contacts, rubber layer 11 can guarantee the wheel with driving wheel
The abundant CONTACT WITH FRICTION of tire avoids slipping, influences detection data.First load bearing roller 3 is identical with 5 diameter of the second load bearing roller, revolution
Diameter of the diameter of roller 4 less than the first load bearing roller 3.Hall sensor 7 is used for the turnning circle of recording disc 6.PLC control device
The information that 8 collectable Hall sensors 7 export is calculated, and controls brake gear 10, is set on the PLC control device 8
There are display screen and operation keyboard.Longitudinal open slot 12, rotary roller 4 are equipped on the isosceles trapezoid monitor station 1 at 4 both ends of rotary roller
The shaft lower part at both ends is respectively mounted spring 13.Rotary roller 4 can float up and down in open slot 12, especially in driving wheel wheel
When tire is not disposed on the first load bearing roller 3 and the second load bearing roller 5, rotary roller 4 is placed in the apex of open slot 12, when driving wheel tire
When being placed on the first load bearing roller 3 and the second load bearing roller 5, driving wheel tire top and rotary roller 4 are tangent, and rotary roller 4 is driving at this time
Rotary roller 4 moves down under the pressure of driven wheel tire, and the roll shaft lower part at 4 both ends of rotary roller is installed with spring 13, in spring 13
Rotary roller 4 is made sufficiently to offset under tension with driving wheel tire, the disk 6 for avoiding rotary roller 4 from driving dallies, and guarantees to count
Accuracy.
When detection, taxi driving wheel row drives simultaneously between the first load bearing roller 3 and the second load bearing roller 5 and being supported by it
Driven wheel tire sufficiently offsets with rotary roller 4, and the parked brake in rear-wheel taxi is defined position, and starting driving wheel actively turns
Rotary roller 4 is driven to operate when dynamic, since 4 diameter of rotary roller is smaller, it is inconvenient to count, thus in the disk of one end installation major diameter
6, the circle number that Hall sensor 7 rotates acquisition rotary roller 4, PLC control device 8 then can be according to the circle number and its circle of rotary roller 4
The parameters such as the diameter of disk 6 play to calculate the mileage of taxi traveling then with the meter mileage comparison in taxi
The purpose of meter detection.
