Problems solved by technology

On the one hand, this standard does not provide an accurate method of pitching radius measurement; on the other hand, when measuring the pitching radius of artillery, the artillery trunnion must be exposed to use a tape measure for direct measurement, and most types of artillery trunnions are usually sealed No exposure, direct measurement is difficult to implement

Embodiment Construction

[0033] Concrete operation steps of the present invention are:

[0034] (1) The artillery to be tested drives into the designated detection area, and the artillery is adjusted vertically and horizontally with a jack, so that the barrel of the artillery is in a horizontal position;

[0035] (2) Accurately paste the crosshairs on the end face of the muzzle, so that the center of the crosshairs represents the center of the muzzle, and the firing pin is removed from the breech to reveal the firing pin hole;

[0036] (3) Set up the theodolite directly in front of the artillery, and turn the artillery direction machine and the height machine so that the optical axis of the theodolite coincides with the center of the muzzle cross and the center of the firing pin hole;

[0037] (4) Turn the gun direction machine until the side of the barrel can be observed in the theodolite, paste two cross marks on the busbar on the side of the barrel, and use the optical axis of theodolite to adjust ...

Abstract

The invention relates to a cannon pitching radius measuring method, and belongs to the technical field of measurement. An indirect measuring method is employed, and the cannon pitching radius measuring method relates to measurement of cannon size data and parameters needed for calculating the deviation angle that the gun bore line deviates the shooting plane. The artillery pitching radius measuring method comprises specific operations that a cannon to be tested travels into an assigned detection area; a cross curve is accurately pasted on the end face of the gun muzzle; a theodolite is erected right ahead the cannon; a steering gear box of the cannon is rotated until one side surface of the gun barrel can be observed in the theodolite; a total station is erected at one side, of the gun barrel, having marks; the pitching angle is in a range from 15 DEG to 20 DEG; and the pitching radius is obtained according to the measuring result. The cannon pitching radius measuring method provides parameters for cannon size data and deviation angle calculation. The measurement precision of the cannon pitching radius measuring method satisfies the usage requirement, and the cannon pitching radius measuring method can be operated conveniently.

Description

technical field [0001] The invention belongs to the technical field of measurement. Background technique [0002] The pitch radius of the gun refers to the distance from the end face of the muzzle to the center of the trunnion shaft, and is one of the main contents of the measurement of the deviation angle (hereinafter referred to as the deviation angle) of the axis of the gun bore from the shooting surface and the measurement items of various elements of the gun size. In the range artillery identification and design finalization test, pitch radius measurement and artillery deviation angle measurement are important assessment items. [0003] In the national military standard with the standard number 2977A-2006, in "7.16 Measurement of the deviation angle of the axis of the gun bore from the shooting surface", in 7.16.6.1.4 calculation formula (25) of the deviation angle, it is necessary to measure [0004] L 5 ——The distance from the end face of the muzzle to the center of...
