Problems solved by technology

[0005] In order to overcome the shortcomings of using a round wooden stick on the top of the head, excessive force will easily cause the lens and the round head of the gyroscope to fall off, causing the concrete mortar to flow out along the gap between the rock and the instrument, and the concrete mortar that comes out will cover the lens of the instrument. Technical problem : Provide a photoelastic instrument auxiliary installer that can quickly install and ensure the cleanliness of the photoelastic strain gauge lens

Abstract

The invention belongs to the technical field of ground pressure monitoring, and in particular relates to an auxiliary installer for a photoelastic instrument. The technical problem is to provide a photoelastic instrument auxiliary installer that can be quickly installed and ensures that the photoelastic stress meter lens is clean. An auxiliary installer for a photoelastic instrument includes a cylindrical sleeve, a casing, etc.; the cylindrical sleeve is provided with a casing. The invention achieves the effects of rapid installation and ensuring the cleanness of the lens of the photoelastic stress meter. The invention achieves the effect of quick installation and ensuring the cleanness of the photoelastic stress meter lens. The clamping device of the invention can quickly assist in clamping the photoelastic stress meter, and drives the clamping device and the photoelastic stress meter into the cylindrical sleeve through the push rod. It can protect the photoelastic stress meter. By pushing the push rod, the clamping device and the photoelastic stress meter are stuck into the cement mortar to achieve coupling with the rock wall. Then the clamping device is released and the ejector pin is reset. The device has a simple structure. , to facilitate and assist in the installation of the photoelastic stress meter.

Description

technical field [0001] The invention belongs to the technical field of ground pressure monitoring, and in particular relates to an auxiliary installer for a photoelastic instrument. Background technique [0002] Ground pressure monitoring is an important part of ground pressure research and a scientific means to reveal the laws of mine ground pressure activities. As a stress analysis method of optical elastic mechanics, photoelastic stress gauge (abbreviated as optical strain gauge) is a simple and practical method to monitor the stress change of ore and rock mass. In practical application, the photoelastic stress gauge can be used as a converter of surrounding rock stress, which can display obvious stress stripes and be observed with a photoelastic instrument. Compared with other electrical stress measurement methods, the optical strain gauge has the advantages of cheap price and convenient observation, and is not affected by harsh underground conditions, such as a very hu...
