Embodiment 1

[0039] Now take the measurement of two degrees of freedom between hydraulic supports as an example, such as figure 1 and 2 As shown, the two-degree-of-freedom measuring device based on plane mirror imaging of the present embodiment is composed of a reference fixed plate 1, a reference plane mirror 2, a fastening connection bolt 3, a camera 5, a mirror frame 4, a horizontal marking rod 6-2, and a longitudinal marking rod 6-1. The fixed plate 8 to be tested, the plane mirror 7 to be tested and the computer 13 are composed.

[0040] Specifically: the reference fixed plate 1 of the present embodiment is a rectangular plate structure, which is used to install the reference flat mirror 2, that is, a rectangular reference flat mirror 2 is installed in the middle part of the reference fixed plate 1, as a measurement reference, on the reference flat mirror 2 The four corners are fastened with fastening bolts 3 and the reference fixed plate 1. Two mounting holes are provided in the mid...

Embodiment 2

[0056] see Figure 8 , the reference fixed plate 1 and the reference plane mirror 2 of the present embodiment, the fixed plate 8 to be measured and the plane mirror 7 to be measured are all fastened by the U-shaped fixing frame 9, that is, the fastening connecting bolt 3 is replaced by the U-shaped fixing frame 9, and the reference The fixed plate 1 is fastened to the reference plane mirror 2, and the fixed plate 8 to be tested is fastened to the plane mirror 7 to be tested. The fixing method of this embodiment is suitable for situations where the site is open and the installation space is large.

[0057] The U-shaped fixed mount 9 of the present embodiment comprises a first U-shaped fixed mount 9 and a second U-shaped fixed mount 9, the first U-shaped fixed mount 9 is used to fix the reference fixed plate 1 and the reference plane mirror 2, and the second U-shaped fixed mount 9 The frame 9 is used to fix the fixed plate 8 to be tested and the flat mirror 7 to be tested, see ...

Embodiment 3

[0062] see Figure 10 , the reference fixed plate 1 and the reference plane mirror 2 of the present embodiment, the fixed plate 8 to be measured and the plane mirror 7 to be measured are all fastened by the double-headed suction cup frame 10, that is, replace the fastening connecting bolt 3 with the double-headed suction cup frame 10, and the reference The fixed plate 1 is fastened to the reference plane mirror 2, and the fixed plate 8 to be tested is fastened to the plane mirror 7 to be tested. The fixing method of this embodiment does not need to drill holes and does not damage the hydraulic support.

[0063] There are 8 double-head suction cup holders 10 in this embodiment, which are divided into two groups, and are respectively distributed on the four corners of the reference plane mirror 2 and the plane mirror 7 to be measured. see Figure 11 and 12 , the double-headed suction cup frame 10 of the present embodiment is made of suction cup 10-1, spring 10-2, intermediate ...

Abstract

The invention relates to a two-degree-of-freedom measuring device and method based on plane mirror imaging. The measuring device includes a reference fixed plate and a fixed plate to be measured, and a reference plane mirror is fixed on the reference fixed plate and the fixed plate to be measured by fastening connectors respectively. and the plane mirror to be measured, the reference plane mirror is arranged opposite to the reflection surface of the plane mirror to be measured, a mirror frame on which a camera can be installed is arranged in front of the reflection surface of the reference plane mirror, a marking rod is arranged on the mirror frame, and the marking rod is parallel to the reference plane mirror, and the camera Connected to the computer through the data line, the invention applies the principle of multiple imaging of the plane mirror, and combines the optical principle with the mechanical structure. High performance, strong survivability, and simple structure, it solves the precise measurement of yaw angle and pitch angle between space planes, and has a guiding role in angle adjustment.

Description

technical field [0001] The invention belongs to the technical field of two-degree-of-freedom measurement, and in particular relates to a device and method for realizing two-degree-of-freedom measurement based on the imaging principle of a plane mirror. technical background [0002] For coal mine automatic fully mechanized mining, its main equipment includes: hydraulic support group, coal shearer and scraper conveyor, a fully mechanized mining face usually has hundreds of hydraulic supports used in groups, for coal shearer, scraper Conveyors, personnel and other equipment provide working space. At the same time, according to the trend of coal seam geology, each hydraulic support is not placed in parallel or vertically, but there is a certain dislocation in space. Due to the lack of coordinates in coal mines, the inclined hydraulic support is not easy to find. When the inclination is large, it is easy to fall down, which will cause the loss of personnel and property, and coal ...
