Adjustable forced centering support for automatic monitoring devices for high speed rails, railway tunnels, reservoir dams and the like

Abstract

An adjustable forced centering support for automatic monitoring equipment such as high-speed railways, subway tunnels, and reservoir dams, including an upper fulcrum, a lower fulcrum, and a base, and is characterized in that the upper fulcrum and the lower fulcrum are fixed on the wall, and the upper fulcrum A horizontal bar is hinged, and there are two lower fulcrums. Left and right oblique struts are hinged on the two lower fulcrums. A base is provided at the upper end of the cross bar, and a base is provided above the base. The invention has the characteristics of simple structure, safety and reliability, and is not easy to be damaged. The monitoring equipment is connected with the base of the bracket through screws to ensure the measurement accuracy.

Description

technical field [0001] The invention relates to a support for monitoring equipment, in particular to an adjustable and forced centering support for automatic monitoring equipment such as high-speed railways, subway tunnels, reservoir dams and the like. Background technique [0002] When performing special precision engineering measurement operations, due to the extremely high precision requirements, the centering error will have a significant impact on the overall error when using vertical ball centering, optical centering or laser centering. Therefore, when using precision instruments to observe, it is often used The method of forced alignment is adopted. [0003] At present, the forced centering method commonly used in precision engineering measurement: during the whole observation process, the position of the instrument remains unchanged, so that there is almost no centering error, but it is difficult to keep the instrument stationary for a long time, and it is only suita...

Problems solved by technology

[0003] At present, the forced centering method commonly used in precision engineering measurement: During the whole observation process, the position of the instrument remains fixed, so that there is almost no centering error, but it is difficult to keep the instrument stationary for a long time, and it is only suitable for short-term projects

In many places, the application is limited, and it cannot meet the long-term measurement. At the same time, it is easy to be damaged and corroded, which limits the accuracy of measurement and its wide application.
