The invention discloses an accurate overspeed and overload embedded part for highway entrance and exit. The accurate overspeed and overload embedded part comprises an embedded rod, wherein a fixing rod is fixedly connected to the top part of the embedded rod in an integrated forming manner; a connector is fixedly connected to the top part of the fixing rod; a sliding part sleeves the surface of the fixing rod; a sliding rail is fixedly connected to the sliding part; a limiting block is fixedly connected to the tail end of the sliding rail; a chuck is fixedly connected to the tail end of the limiting block; a sliding block is in sliding connection with the sliding rail; an adjusting cylinder is hinged to the top part of the fixing rod; and the tail end of a piston rod on the adjusting cylinder is hinged to the sliding block on the sliding rail. The embedded part is high in stability and hard to swing after being embedded, so that convenience is provided for people, and the overspeed andoverload monitoring can be conveniently performed.
Description
technical field [0001] The technical field of overspeed and overload measurement of the present invention, in particular, relates to an overspeed and overload pre-embedded part for precise high-speed entrance and exit. Background technique [0002] At present, there are many settlement observation points for high-speed railway operation and maintenance, heavy observation tasks, high precision, and high automation in the operation process. When the existing measuring devices are used, different types of measuring equipment need to be fixed by different embedded parts, and There is no agreed measurement mark component, but after the existing embedded parts are buried, they have low stability after long-term use, which causes certain inconvenience to people's use. Contents of the invention [0003] The purpose of the present invention is to provide a precise high-speed entrance and exit super-speed and overload built-in parts to solve the problems raised in the above-mentione...
