Abstract
The utility model relates to a four-full type digital display steel rail abrasion wear detecting instrument which comprises a vertical abrasion rule, a side abrasion rule and a positioning block; wherein the side abrasion rule is horizontally arranged at the left end of a main base; the vertical abrasion rule is vertically arranged on the horizontal surface of the main base; the positioning block is arranged at the right lower part of the main base; and digital display devices are respectively arranged on the vertical abrasion rule and the side abrasion rule. The detecting instrument can be used for measuring the cross section abrasion wear of different steel rails of 43Kg/m, 50Kg/m, 60Kg/m and 75Kg/m, realize the mutual exchange of practicability during the detection, implement normalized data management and provide more reliable safety guarantee for safety detection of urban subway rails of public service lines and prevention of derailment accidents of locomotive vehicles.
Description
Technical field: the utility model relates to four full formula digital display Rail Abrasion Detection System instrument, is the special detector that is used to measure the rail profile abrasion.
Background technology: detect rail profile abrasion vernier caliper at present, abrasion, the measurement data that can not measure rail vertical plane, side point simultaneously be inaccurate, can not in time grasp the rail profile degree of injury.Influenced the be engaged in safety detection of circuit of worker, exist the worker be engaged in circuit city underground track can not safety detection, the hidden danger of rolling stock derailing.
Summary of the invention: purpose of the present invention will provide a kind of four full formula digital display Rail Abrasion Detection System instrument exactly, and it can overcome present detection rail profile and wear away inaccurate existing problem.The purpose of this utility model is to realize like this, four full formula digital display Rail Abrasion Detection System instrument, comprising that the mill chi that hangs down, side grinding chi, locating piece form, it is characterized in that: the left end of the seat of honour has been horizontally disposed with the side grinding chi, be vertically installed with the mill chi on the surface level of the seat of honour, the lower right of the seat of honour is provided with locating piece; Be respectively arranged with device for digit-displaying on described vertical mill chi, the side grinding chi.Detector of the utility model can be used for measuring the section abrasion of 43Kg/m, 50Kg/m, the different rail of 60Kg/m, 75Kg/m, practicality when having realized detecting is exchanged, it to the worker be engaged in circuit city underground track safety detection and prevent the rolling stock derailment accident, carry out the standardization data management, more reliable safety guarantee is provided.
Important technological parameters:
1. detection position: according to the worker of the Ministry of Railways maintenance definition 3.4.2 bar of being engaged in, vertical abrasion are measured at wide 1/3 place of rail surface, and side wear is the measurement of 16mm place under rail tread.
2. sensing range: vertical abrasion: 0-15mm; Side wear: 0-25mm.
3. show: the liquid crystal display reading.
4. accuracy of detection: ± 0.1mm.
5. reading resolution: 0.01mm.
6. working temperature: 0-+40 ℃.
7. relative temperature: Φ≤80%.
8. storage temperature :-20 ℃-+70 ℃.
9. be measured as mechanical type chi bar scale reading and banyan grid sensing liquid crystal digital and show the reading measurement.
Description of drawings:
Structural representation when Fig. 1 is the utility model actual measurement;
1. mill chi, 2. side grinding chi, 3. module, 4. locating piece, the 5. seat of honour hang down.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
Four full formula digital display Rail Abrasion Detection System instrument, comprising that the mill chi 1 that hangs down, side grinding chi 2, locating piece 4 form, it is characterized in that: the left end of the seat of honour 5 has been horizontally disposed with side grinding chi 2, is vertically installed with mill chi 1 on the surface level of the seat of honour 5, and the lower right of the seat of honour 5 is provided with locating piece 4; Be respectively arranged with device for digit-displaying on described vertical mill chi 1, the side grinding chi 2.During concrete enforcement, with locating piece curved surface and inoperative side, the yoke face is closely connected seamless, advancing hangs down grinds chi, side grinding chi, reads vertical abrasion and side wear value respectively by the device for digit-displaying display digit.On the occasion of being wearing valve, negative value is for being higher than standard section profile value.Pull out two gauge heads of hang down mill chi, side grinding chi respectively, avoid damaging when the road is measured under instrument gauge head.Change battery, take off battery case lid and change new anode up, prevent the both positive and negative polarity short circuit by the primary element position.Changing 43Kg/m, 50Kg/m, 60Kg/m tightens lock screw as long as shift locating piece onto extreme position during 75Kg/m rail locating piece again.
