Spherical washer

Abstract

The present invention proposes a spherical washer, which includes a concave ball washer and a convex ball washer that are used in pairs. The concave ball washer is a hollow cylinder with a through-hole of the concave ball washer inside and communicated with the concave ball washer. A concave spherical surface with the holes connected to and concave toward the through hole of the concave ball pad; the convex ball pad is a truncated hollow spherical body, and its side surface is a convex spherical surface that protrudes outwards; wherein, the concave spherical surface and the convex spherical surface are The spherical surfaces have the same spherical radius; the concave spherical surface is matched with the convex spherical surface, so that the concave spherical pad and the convex spherical pad are inlaid into one body. When the outer working surface is inclined or uneven, the concave ball pad and the convex ball pad of the spherical washer of the present invention can contact and adjust the alignment by themselves, so as to ensure the neutrality and contact area of ​​the carrier used by the outside world, thereby ensuring the smooth operation of the anchor cable sensor. The installation improves the installation efficiency, and has the characteristics of simple structure, low cost, easy installation and convenient use.

Description

technical field

[0001] The invention relates to the field of mechanical engineering components, in particular to a spherical washer. Background technique

[0002] At present, in the field of civil engineering, anchor cable sensors are usually used to measure or monitor the stress of bridge cables, anchor cables for slope treatment, and anchor rods for mountain tunnels. However, engineers and technicians often install anchor cable sensors. It will encounter the problem that the anchor cable sensor cannot fit well with the measured plane due to the uneven inclination of the measured surface, resulting in deviation of the measured data, and when the measured surface is too inclined, the anchor cable sensor will not be able to Install. In order to ensure that the sensor can be installed correctly, engineers and technicians need to spend a lot of manpower and time to gouging the measured surface, which is very uneconomical, time-consuming and labor-intensive. Therefore, there i...
