Abstract

The utility model relates to a railway gauging rule leveler, which is used for detecting the level of two railway tracks and a high and low value. The leveler is improved on the basis of the traditional cylindrical helical leveler, and is characterized in that: the situation that the axis of a sliding contact and the axis of a horizontal connecting rod are in the same straight line in the traditional gauging rule leveler is changed into the situation that the axis of the sliding contact is perpendicular to the axis of the horizontal connecting rod, and the situation that the sliding contact is arranged in a helical groove arranged on the section of the transverse center of the cylindrical helical body is changed into the situation that the sliding contact is arranged in the helical groove on the section of the longitudinal center of the cylindrical helical body, thereby the idle stroke phenomenon generated when the rotating direction of a circular dial is changed can be avoided, the accuracy of the horizontal height difference between the two rails measured by the gauging rule is improved, and simultaneously, the situation that the accuracy of the horizontal height difference between the two rails is affected when the error between the processed and manufactured helical surface of the cylindrical helical body and the perpendicularity of the axis of the cylindrical spiral body exists can be avoided.

Description

A kind of railway gauge chi level gauge
Affiliated technical field
The utility model belongs to the measuring apparatus technical field, specifically refers to a kind of a kind of railway gauge chi level gauge that detects railroad track two rail levels and high low value thereof.
Background technology
The railway gauge chi is a kind of survey tool of rail track, the railway gauge chi of the present usefulness of China is except that can measuring two strands of gauges between rail, also to measure the difference in level between two strands of rail of railway, present domestic gauging rule is measured the rail track difference in level and is used commonplace level gauge, its structure is a kind of cylindrical screw structure, this structure is to utilize similar triangles geometric ratio relation, utilize spiral lifting to make air level principle placed in the middle, measure two bursts of difference in level between rail, because the slider axis of air level assembly and waling stripe axis are on same straight line in this structure, and slider is arranged in the helicla flute of cylindrical screw body transverse center tangent plane position, thereby causes the air level assembly only not to be subjected to responsive to axial force merely.When the rotation circular scale, slider can be done upper and lower slip along helicoid in helicla flute, it is left and right mobile also will to do horizontal direction simultaneously, when there are error in processing and fabricating helicoid and cylindrical screw body axis verticality, can influence the accuracy of two bursts of difference in level indicating values between rail like this.In addition, because inevitably there is certain clearance in each drive disk assembly, when the circular scale clockwise direction rotates and counterclockwise rotate conversion mutually, will inevitably produce the idle stroke of a trace, thereby also can influence the accuracy of two bursts of difference in level indicating values between rail.
Summary of the invention
It is a kind of simple for production that the purpose of this utility model is to provide, and operates, observes convenient and can improve the gauging rule level gauge that gauging rule is measured the difference in level accuracy between two strands of rail.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of railway gauge chi level gauge, constitute by protective cover, cylindrical screw body, circular scale, circular scale reading pointer, the superelevation groove, watch window and the air level assembly that are engraved on the circular scale, circular scale is fixedly mounted on cylindrical screw body top, be positioned at the protective cover outside, circular scale reading pointer is installed on the protective cover corresponding with the circular scale position; Described air level assembly comprises air level, waling stripe and slider, and air level is installed on the waling stripe, and waling stripe is provided with slider by rotating shaft location, waling stripe top, and slider is arranged in the helicla flute of cylindrical screw body; Watch window is arranged on the protective cover corresponding with the air level position, and described slider axis is vertical mutually with the waling stripe axis, and slider is arranged in the helicla flute of cylindrical screw body longitudinal center tangent plane position.
The beneficial effects of the utility model are, because it is the slider axis in the former gauging rule level construction is vertical mutually by changing on same straight line with the waling stripe axis, slider is arranged in the helicla flute of cylindrical screw body transverse center tangent plane position, change into slider is arranged in the helicla flute of cylindrical screw body longitudinal center tangent plane position, thereby make air level assembly axially loaded always, so no matter how the circular scale rotation direction is changed, circular scale can not produce the idle stroke phenomenon, avoid each drive disk assembly to have the influence of certain interval, thereby can improve the accuracy that gauging rule is measured the difference in level between two strands of rail; Simultaneously, can make slider when helicoid is made upper and lower slip fortune, it is on a certain concentric circles at center that its contact point remains at the cylindrical screw body axis, thereby when avoiding there is error, influence the accuracy of two bursts of difference in level indicating values between rail because of the cylindrical screw body helicoid of processing and fabricating and cylindrical screw body axis verticality.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a structural representation of the present utility model:
Fig. 2 is the vertical view of Fig. 1.
By Fig. 1, shown in Figure 2,1 is that protective cover, 2 is helicla flute for rotating shaft, 11 for slider, 10 for waling stripe, 9 for air level, 8 for watch window, 7 for the superelevation groove on the circular scale, 6 for circular scale reading pointer, 5 for circular scale, 4 for cylindrical screw body, 3.
The specific embodiment
As shown in Figure 1 and Figure 2, this railway gauge chi level gauge, constitute by superelevation groove 5, watch window 6 and air level assembly on protective cover 1, cylindrical screw body 2, circular scale 3, circular scale reading pointer 4, the circular scale, circular scale 3 is fixedly mounted on cylindrical screw body 2 tops, be positioned at protective cover 1 outside, circular scale reading pointer 4 is installed on the protective cover 1 corresponding with circular scale 3 positions; The air level assembly comprises air level 7, waling stripe 8 and slider 9, air level 7 is installed on the waling stripe 8, waling stripe 8 is provided with slider 9 by rotating shaft 10 location, waling stripe 7 tops, and slider 9 is arranged in the helicla flute 11 of cylindrical screw body 2; Watch window 6 is arranged on the protective cover 1 corresponding with air level 7 positions, and slider 9 axis are vertical mutually with waling stripe 7 axis, and slider 9 is arranged in the helicla flute 11 of cylindrical screw body 2 longitudinal center tangent plane positions, can slide in helicla flute 11.
In the railway track measurement operation, rotate circular scale 3, thereby make cylindrical screw body 2 drive slider 9 upper and lower slip in helicla flute 11, and drive waling stripe 8 along rotating shaft 10 upper and lower moving, air level 7 on the while eye-level connecting rod 8, after air level 7 moves to horizontal level between two parties, read the indicating value on the superelevation groove 5 on the circular scale that coincides with circular scale reading pointer 4, be measured numerical value.
