Abstract
The utility model discloses a kind of taximeter pick-up unit, comprise an at right angles trapezoidal monitor station, be provided with revolving cylinder in monitor station, revolving cylinder upper end is exposed on the surface level of monitor station, and drum shaft supports fixing through bracing frame; Bracing frame is separately provided with Hall element and brake gear; The inclined-plane of monitor station is provided with lifting block; Separately be provided with PLC control device in monitor station, the information that PLC control device can collect the output of Hall element is calculated, and can control the duty such as brake gear, lifting block.Its scientific structure design, convenient to operation, avoid the error that driving wheel squeegee action in testing process, revolving cylinder bearing clearance, vibration and size out of true etc. are brought, improve the accuracy of testing result.
Description
Technical field
The utility model relates to a kind of checkout equipment of measurement instrument, particularly relates to a kind of taximeter pick-up unit.
Background technology
Taximeter is by measuring distance travelled of hiring a car, and then show the pricing device of final charge in conjunction with unit price, its accuracy directly affects the fairness of transaction.At present for the pick-up unit of taximeter usually by the drum apparatus that can rotate with the mileage such as taxi driving wheel, sensor and the computerized information processing section of detecting the drum rotating number of turns are formed, and drum apparatus adopts spaced two cylinders usually, during detection, taxi driving wheel is positioned at above two cylinders, three is tangent, this ensure that the collection of taxi driving wheel distance travelled, but its tire that have ignored taxi driving wheel be have flexible, deformable, in testing process wheel stressed after sex change and normal traveling there is bigger difference, therefore affect testing result.In addition, owing to adopting twin-roll design, this kind of cylinder general diameter is less, therefore the factors such as gap between drum shaft and rotating connector thereof, vibration and accuracy to size bring larger error, also affects the accuracy of taximeter detection.
Utility model content
For overcoming prior art problem, the utility model provides a kind of easy to operate, and cost is lower, detects taximeter pick-up unit comparatively accurately.
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of taximeter pick-up unit, comprise an at right angles trapezoidal monitor station, one is provided with for carrying the revolving cylinder of the driving wheel of taxi in described monitor station, revolving cylinder upper end is exposed on the surface level of monitor station, and the drum shaft at revolving cylinder two ends supports fixing through bracing frame; Described bracing frame is separately provided with the Hall element that record revolving cylinder rotates the number of turns and the brake gear that revolving cylinder can be stoped to rotate; The inclined-plane of described monitor station is provided with a lifting block for stoping taxi trailing wheel to glide, described lifting block provides lifting drive by motor; Separately be provided with PLC control device in described monitor station, the information that PLC control device can collect the output of Hall element is calculated, and can control the duty such as brake gear, lifting block; Described PLC control device is provided with display screen and operation keyboard; The diameter of described revolving cylinder is greater than 2 times of driving wheel diameter to be detected.
The utility model has following beneficial effect: during detection, taxi driving wheel is supported by revolving cylinder, trailing wheel then limits position by lifting block, revolving cylinder running is driven during driving wheel active rotation, and Hall element will gather the number of turns of revolving cylinder rotation, the parameters such as the diameter of the number of turns that PLC control device then can rotate according to revolving cylinder and revolving cylinder thereof calculate the mileage that taxi travels, and namely serve the object that fee register detects.It simulates the stressing conditions of driving wheel when taxi normally travels preferably in testing process, avoids driving wheel distortion and impact on testing result; Because it adopts an independent revolving cylinder to carry out support drive wheel, therefore friction force between revolving cylinder and driving wheel is larger, the situation that can not occur to skid occurs, and can support drive take turns because revolving cylinder must have larger diameter, then reduce the error that bearing clearance, vibration and size out of true etc. are brought thus; In testing process, brake gear, lifting block carry out cooperation control by PLC control device, convenient to operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation after the utility model cross-section.
Embodiment
Shown in Fig. 1,2, a kind of taximeter pick-up unit, comprise an at right angles trapezoidal monitor station 1, one is provided with for carrying the revolving cylinder 5 of the driving wheel 11 of taxi in monitor station 1, revolving cylinder 5 upper end is exposed on the surface level of monitor station 1, and the drum shaft 12 at revolving cylinder 5 two ends supports fixing through bracing frame 8; Bracing frame 8 is separately provided with the Hall element 10 that record revolving cylinder 5 rotates the number of turns and the brake gear 9 that revolving cylinder 5 can be stoped to rotate; The inclined-plane of described monitor station 5 is provided with a lifting block 6 for stoping the trailing wheel 13 of taxi to glide, described lifting block 6 provides lifting drive by motor 7; The information that PLC control device 3, PLC control device 3 can collect the output of Hall element 10 is separately installed in described monitor station 1 calculated, and the duty of the parts such as brake gear 9, lifting block 6 can be controlled; Described PLC control device 3 is provided with display screen 4 and operation keyboard 2; The diameter of described revolving cylinder 5 is greater than 2 times of driving wheel 11 diameter to be detected.
During detection, driving wheel 11 is supported by revolving cylinder 5, trailing wheel 13 limits position by lifting block 6, revolving cylinder 5 is driven to operate during driving wheel 11 active rotation, and the number of turns that collection revolving cylinder 5 rotates by Hall element 10, the PLC control device then parameter such as 3 number of turns can rotated according to revolving cylinder 5 and diameter thereof calculates the mileage of taxi traveling, namely serves the object that fee register detects.
