Monitoring device for strained condition of pressure dispersion anchorage cable based on force transmitting board

Abstract

The invention discloses a pressure dispersion type anchor rope stress state monitoring device based on a force passing plate, relates to a anchor rope stress state monitoring device, mainly solves the force passing problem when the prestress between an expansion plate and an anchor backing plate is stretched and drawn, and effectively avoids the problem that the anchor backing plate can be damaged when the anchor rope is stretched and drawn when the pressure dispersion type anchor rope stress state is monitored. The monitoring device comprises an anchor plate (10), an anchor rope force meter (20), an expansion plate (30), an anchor backing plate (40) and a force passing plate (40). The anchor backing plate (40), the force passing plate (50), the expansion plate (30), the anchor rope force meter (20) and the anchor plate (10) are connected in sequence. The force passing plate (50) is provided with a round ring bass hollow thick round plate. The invention can avoid the phenomena that the anchor backing plate (40) can be damaged, and is suitable for monitoring the artificial side slopes or sliding slopes reinforced by the pressure dispersion anchor rope in the projects, such as high ways, railways, mines, hydropower stations, and the like.

Description

technical field [0001] The invention relates to a monitoring device for the stressed state of the anchor cable, in particular to a pressure dispersion type monitoring device for the stressed state of the anchor cable based on a force transmission plate; The problem of force transmission during tension can effectively avoid the problem that the anchor plate may be damaged when the anchor cable is tensioned when the force state monitoring is carried out on the pressure dispersion anchor cable. Background technique [0002] From the perspective of natural disasters, the loss caused by landslides to all countries in the world may be second only to earthquakes and tsunamis. Many countries, including China, are countries with relatively serious landslide disasters. According to statistics in recent years, the loss of economic construction and people's life and property caused by geological disasters caused by slope instability is nearly 30 billion yuan in our country every year. ...

Problems solved by technology

[0007] However, in practical applications, it is found that there is a phenomenon that the anchor plate 40 is destroyed when the prestress is applied.

This is because the anchor plate 40 is a cast iron body, and the anchor plate 10 will be embedded in the depression of the anchor plate 40 when it is installed, so that the main force-bearing part is the depression when the anchor cable is stretched, and the anchor plate 40 One part is thicker and will not be damaged when the prestress is applied to the anchor cable; but when installing the pressure dispersion type anchor cable stress state monitoring device, in order to meet the installation of the anchor cable dynamometer 20, a The expansion plate 30, because the diameter of the expansion plate 30 is larger than the concave diameter of the original anchor plate 40, the force-bearing part changes when the anchor cable is stretched, and the thinner part of the anchor plate 40 bears the pressure, so that the anchor plate 40 It may be damaged under pressure, and normal stress state monitoring cannot be carried out
