Abstract
The utility model relates to a reduce value measuring instrument, particularly relates to a special measuring tool for measuring high speed railway and passenger transport line point detection and maintenance, namely, a tongue reduce value measuring instrument, which is composed of a frame and a data storage display system. The frame comprises two slide rails that are arranged in a parallel way, a fixation base, a scale, a sliding base and auxiliary legs; the two slide rails that are arranged in parallel are provided with a measure mechanism that can slide back and forth in a horizontal direction, and the measure mechanism is provided with a linear displacement sensor; the auxiliary legs are detachable and folding; the data storae system can display the output result in real time and store 20 groups of metrical data. The utility model can measure the reduce value of a tongue relative to a stock rail and that of a point rail superface lower than a wing rail based on a measure displacement sensor. In the utility model, the tongue reduce value measuring instrument can combine based on measure requirement, and is provided with feathres like small size, light weight, high measure efficiency and convenient operation, and can reduce labor intensity for workers.
Description
Affiliated technical field
The utility model relates to a kind of reduction value measuring instrument, and relating in particular to a kind of special measurement instrument that is used for the laying of measurement high speed railway and Line for Passenger Transportation track switch, inspection and maintenance is tongue reduction value measuring instrument.
Background technology
To be rolling stock change or cross the line facility of another strand track over to from one track to track switch, is the important component part of railroad track.Track switch is the weak link on the circuit, is one of the key of the safety of line influence train running speed.As far as high-speed railway, track switch is occupied crucial special status.Along with opening in succession of China Express Railway and Line for Passenger Transportation built and operation, high-speed railway and the maintenance of Line for Passenger Transportation track switch routine servicing are brand-new problems.
When track switch is laid and is used, according to " track switch is laid the handbook requirement, and point tongue need be provided with different reduction values with respect to stock rail apart from four different section parts of the point of switch; Same road frog rail need be provided with different reduction values with respect to wing rail at most advanced and sophisticated three the different sections of centroid rail.
The laying of track switch, inspection and adjust determining the whether raising of safety and the speed of service of train operation.And present domestic track switch checks that laying, detection do not have complete special tool and corresponding with it construction technology with maintenance tool, can't form unified standard, can't reach the requirement of " protect technology, protect construction quality with technology with equipment frock ".Reality is that the workman measures tongue reduction value and heart rail reduction value by means of clearance gauge and leveling ruler, obviously can not satisfy required precision, and operating efficiency is low.Therefore, it is just necessary to develop light, high-precision tongue reduction value measurement mechanism-tongue reduction value measuring instrument, to satisfy track switch inspection and the on-the-spot needs that keep in repair.
Summary of the invention
For the defective that the efficient that overcomes prior art is hanged down low precision, the utility model provides a kind of high-precision tongue reduction value measuring instrument of automation.
The utility model solves the technical scheme that its technical problem adopted: a kind of tongue reduction value measuring instrument is characterized in that being made up of frame and storage display system.Frame is by placing two slide rails that are arranged in parallel, measuring mechanism, holder, scale, slip base and auxiliary supporting leg in the frame to form.On said two slide rails that are arranged in parallel the measuring mechanism that can laterally slidably reciprocate is housed, Linear displacement transducer (hereinafter to be referred as sensor) is housed on the measuring mechanism, this sensor is one of core component that guarantees certainty of measurement.
When carrying out the measurement of frog rail reduction value, frame need not be installed auxiliary supporting leg.The frame holder places one to survey on the wing rail, stirs slip base to another wing rail, and movable sensor is located at heart rail top, can record the reduction value of heart rail with respect to wing rail by the lower sensor handgrip.
When carrying out the measurement of point tongue reduction value, auxiliary supporting leg must be installed, be combined into frame main body.The frame holder places on the stock rail, and directly over stock rail, movable sensor is located at the tongue top, can record the reduction value of tongue with respect to stock rail by the lower sensor handgrip with scale " 0 " position.
Above-mentioned measurement result is sent into single-chip microcomputer automatically and is stored, and is shown in real time by the LCD LCDs that is installed in the frame top.And can be as required, " on turn over " of push dish or " turning over down " button are transferred the data of storage.
Auxiliary supporting leg is detachable and collapsible.
In a word, the utility model can carry out the dismounting combination according to measurement requirement, and volume is little, and is in light weight, is easy to carry; LCD LCDs, scale place above the frame, are convenient to reading and contraposition, and efficiency of measurement is high; And sensor operated is convenient, can alleviate working strength of workers greatly.
Below in conjunction with accompanying drawing the utility model is done further explanation:

The specific embodiment
As shown in Figure 2, when carrying out the measurement of point tongue reduction value, will assist supporting leg 3 to connect through four bolts 2 earlier, be combined into frame main body.Frame holder 5 places on the stock rail, and directly over stock rail, movable sensor 9 is located at the tongue top, can record the reduction value of tongue with respect to stock rail by lower sensor handgrip 1 with scale 8 " 0 " positions.
As shown in Figure 1, to carry out the frog rail and reduce when measuring, frame need not be installed auxiliary supporting leg 3.Frame holder 5 places one to survey on the wing rail, stirs slip base 6 to another wing rail, moves to be installed in two sensors 9 on the parallel sliding track 7 and to be located at heart rail top, can record the reduction value of heart rail with respect to wing rail by lower sensor handgrip 1.
Auxiliary supporting leg 3 can be folding through joint 4, makes easy to carry; When auxiliary supporting leg 3 needs to connect or dismantles, can realize through four bolts 2.
As shown in Figure 3, work finishes, and unclamps bolt 11 and can rechargeable battery 10 be ejected, so that charging.
As shown in Figure 4, above-mentioned measurement result is sent in the single-chip microcomputer automatically and is stored, and is shown in real time by the LCD LCDs 12 that is installed in the frame top.Also can be as required, " on turn over " of push dish 13 or " turning over down " button are transferred the data of storage.
Claims (3)
1. a tongue reduction value measuring instrument is characterized in that comprising frame and storage display system, and said frame comprises two slide rails that are arranged in parallel, holder, scale, slip base and auxiliary supporting leg.
2. tongue reduction value measuring instrument as claimed in claim 1 is characterized in that said two slide rails that are arranged in parallel place in the frame, and the measure linear displacement transducer is installed.
