Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] Such as figure 1 , figure 2 , image 3 as well as Figure 4 As shown, among them, figure 1 It is schematically shown that the vertical displacement measuring device 100 includes a control cabinet, an automatic lifting assembly 2 , a cover plate 3 and a trigger switch bracket 4 .

[0033] The vertical displacement measuring device 100 of the present application is mainly used for calibrating the accuracy of the automatic penetrometer 200 .

[0034] The control cabinet is mainly used to control the lifting function of the relevant components in the automatic lifting assembly 2 .

[0035] The automatic lifting assembly 2 is connected with the control cabinet. For example, there can be both electrical and mechanical connections.

[0036] The cover plate 3 is arranged on the upper end of the automatic lifting assembly 2 and can carry the automatic penetrometer 200...

Abstract

The invention relates to a vertical displacement measurement device and a calibration method therefore. The device is used for calibrating an automatic penetrometer, and comprises a control cabinet; an automatic lifting assembly which is connected with the control cabinet; a cover plate which is disposed at the upper end of the automatic lifting assembly, can support the automatic penetrometer, and can make vertical movement under the action of the control cabinet; and trigger switch supports which are relatively disposed at two sides of the upper end of the automatic lifting assembly, can limit the vertical movement of the cover plate and detects the vertical movement of the cover plate. The device can precisely judge the accuracy of the automatic penetrometer.

Description

technical field [0001] The invention relates to the technical field of equipment calibration, in particular to a vertical displacement measuring device and a calibration method thereof. Background technique [0002] Asphalt penetration is one of the main quality indicators of asphalt, which can clearly reflect the rheological properties of asphalt, and it is an indicator of the softness, hardness and consistency of asphalt. The needle penetration is measured according to the measurement method stipulated in the national standard, that is, it is expressed by the depth that a standard needle penetrates directly into the asphalt sample under a certain load, temperature and time, usually in units of 0.1 mm. [0003] The Asphalt Penetration Meter is the main instrument for measuring the penetration, and it is especially suitable for the determination of residues after evaporation of road petroleum asphalt and liquid petroleum asphalt. [0004] At present, the displacement value ...
