Abstract
The patent relates to a special precision reflection prism for track monitoring. The special precision reflection prism of track monitoring includes: the base is hinged with the pyramid prism shell; the base is fixedly connected to the rail waist or the sleeper; the corner cube is rotatable along a hinge axis with the corner cube housing. The utility model has simple structure, the precision is consistent with that of the traditional prism, and the safety is equivalent to that of the traditional reflecting sheet, thereby improving the measurement accuracy and weakening the influence on the driving safety.
Description
Technical Field
The patent relates to optics, in particular to a special precision reflection prism for track monitoring.
Background
For a long time, monitoring in a protection area of a urban rail or a railway cannot perform substantial high-precision horizontal displacement measurement, and mainly because a reflector needs to be fixed in the horizontal displacement measurement, a measuring instrument robot can accurately measure the variation of a structure. The traditional reflector plate has high safety but poor precision; the precision reflection prism has high precision, but most of the precision reflection prism is made of metal materials such as iron materials or aluminum alloys, for example, the aging of adhesive glue or the falling-off of fixing screws easily causes great potential safety hazards to traveling crane.
Disclosure of Invention
This patent provides a special accurate reflection prism of track monitoring, has overcome the unable problem of installing of accurate reflection prism. The specific technical scheme is as follows:
the special precision reflection prism of track monitoring includes: the base is hinged with the pyramid prism shell; the base is fixedly connected to the rail waist or the sleeper; the corner cube is rotatable along a hinge axis with the corner cube housing.
In one preferred embodiment, the hinge shaft is a bolt shaft.
In a second preferred scheme, one end face of the cylindrical shell is open, and light enters and exits the reflecting prism from the end face; the center of the other end face of the cylindrical shell is provided with a first hinging handle (2).
In a third preferred scheme, the base is a cylinder (3), one bottom surface of the cylinder is fixedly connected with the rail web or the sleeper through glue, and a second hinge handle (4) is arranged at the center of the other bottom surface of the cylinder.
The utility model has simple structure, the prism head adopts the traditional pyramid prism, the bracket and the prism shell adopt environment-friendly silica gel materials, the prism head and the shell adopt sealant for waterproof treatment, the precision is consistent with that of the traditional prism, and the safety is equivalent to that of the traditional reflecting sheet, thereby not only improving the measurement accuracy, but also weakening the influence on the driving safety.

Detailed Description
Embodiments of the present patent are described with reference to fig. 1-3.
The special precision reflection prism of track monitoring includes: the base is hinged with the pyramid prism shell; the base is fixedly connected to the rail waist or the sleeper; the corner cube is rotatable along a hinge axis with the corner cube housing. The pyramid prism shell is cylindrical, one end face of the cylindrical shell is open, and light rays enter and exit the reflecting prism from the end face; the center of the other end face of the cylindrical shell is provided with a first hinged handle 2; the base is a cylinder 3, one bottom surface of the cylinder is fixedly connected with the rail web or the sleeper through glue, and a second hinge handle 4 is arranged at the center of the other bottom surface of the cylinder; the first hinging handle and the second hinging handle are hinged through a bolt shaft 5.
The bracket and the prism shell are made of environment-friendly silica gel materials, waterproof treatment is carried out between the prism head and the shell by adopting sealant, and the precision is consistent with that of a traditional prism.
After the direction is adjusted, the high-strength building nail-free adhesive is adopted to be stuck on the rail web or sleeper.
