Vertical intelligent force measurement support

Abstract

The invention relates to a vertical intelligent force measurement support which comprises an upper pendulum, a lower pendulum and a base, wherein the lower surface of the upper pendulum is a convex spherical surface, the upper surface of the lower pendulum is a concave spherical surface, the upper pendulum is in spherical contact with the lower pendulum, the lower pendulum is arranged on the base, is provided with at least one resistance strain element on the peripheral cylindrical surface thereof and generates the circumferential horizontal pulling force under the action of the upper pendulum spherical normal compressive strain, the circumferential horizontal pulling force enables the resistance strain element on the peripheral cylindrical surface of the lower pendulum to vary, and the variable quantity reduces the size of load acting on the intelligent force measurement support after collection, analysis and treatment of a data collection module. The vertical intelligent force measurement support can be used as a support of a bridge, a building or other engineering structures, is used for testing and monitoring various loads including vertical loads such as static load, dynamic load, impact load and the like for a long term, in particular to monitoring the reaction force of a high-speed railway bridge support, and has important practical significance on ensuring the safety of high-speed railway operation.

Description

technical field [0001] The invention relates to a bridge force-measuring support, in particular to a vertical intelligent force-measuring support capable of automatically testing loads acting on structures in the vertical direction. force support. Background technique [0002] The rapid development of transportation infrastructure has taken up a lot of valuable land resources. In order to save the increasingly scarce land, in recent years, it has become more and more common to use bridges instead of roads in the construction of high-speed railways. For example, the bridges of the Beijing-Shanghai high-speed railway account for more than 80% of the total line length. In order to ensure the safe operation of trains with a speed of 350 kilometers per hour on a line with so many bridges, it is extremely important to monitor and know whether each bridge is in good working condition at any time, and it is an indispensable measure to avoid catastrophic accidents . [0003] The g...

Problems solved by technology

[0004] At present, there is no test automation and cost-effective force-measuring bearing at home and abroad that can be used for safety monitoring of high-speed railway bridges or other bridges. Either the technical performance cannot meet the requirements, or the cost is high, and it is not suitable for mass use.
