AI Technical Summary

Technical Problem

Once the existing force measuring support is damaged, it will be difficult to replace, resulting in the loss of the force measuring function of the support, which requires overall replacement, which increases the cost.

Method used

A vertical force measuring ball bearing with replaceable force measuring elements is designed, and the force measuring elements can be detachable and replaced by the cooperation of a multi-layer seat plate and a fixed friction pair, including a cover plate, a pull-out plate, a force sensor and a central pressure plate.

Benefits of technology

The force sensor is replaced, avoiding the need to replace the bearing as a whole, reducing maintenance costs, and ensuring the force measurement function of the bearing throughout its life cycle.

Abstract

A vertical force-measuring ball bearing with a replaceable force-measuring element is provided with a bearing body with multiple layers of seat plates arranged in coordination with each other layer by layer. The bottom seat plate and the second-to-last seat plate are in a fixed state. A force-measuring element and a fixed friction pair are provided between the bottom seat plate and the second-to-last seat plate. The fixed friction pair is composed of a fixed metal slide plate provided on the bottom surface of the second-to-last seat plate and a fixed non-metal slide plate provided on the bottom surface of the bottom seat plate basin. A mounting groove for installing a replaceable force-measuring element is provided from the side of the bottom seat plate to the center of the bottom seat plate and the fixed non-metal slide plate. The replaceable force-measuring element includes a cover plate, a drawer plate, a force sensor and a center pressure plate. When the force-measuring element loses its function, the force-measuring element can be replaced without replacing the bearing as a whole, thereby providing a reliable full-life cycle monitoring technology for bridges or buildings.
