A large-tonnage graded continuous force-measuring force-adjusting support and cluster control system

Abstract

The invention discloses a large-tonnage graded continuous force measurement and adjustment support and cluster control system. The system comprises multiple support body systems, a force measurement sensing acquisition system, a force adjustment system and a monitoring analysis control system. A fiber grating force measurement module installed in each support body system transmits wave length change information of reflecting light waves to a fiber grating data acquisition instrument through an optical fiber signal line, acquired reflecting light wave length data are then transmitted to a dataprocessing terminal of the monitoring analysis control system through a network to be processed, and therefore force adjustment control is achieved through the monitoring analysis control system. By the adoption of the support and cluster control system, graded continuous synchronous multiple-times force measurement and adjustment of large-tonnage and super-tonnage support clusters can be achieved; and manual field detection or far-end long-term continuous effective automatic monitoring of the support clusters can be achieved, and database analysis, evaluation and early warning are correspondingly conducted.

Description

technical field [0001] The invention relates to the technical fields of highways, railways, urban bridges and building structure engineering, in particular to a large-tonnage graded continuous force-measuring force-adjusting support and a cluster control system. Background technique [0002] The support is an important part connecting the upper and lower structures, and can reliably transmit the dead load, live load and deformation (displacement and rotation angle) of the upper structure to the lower structure. The spherical bearing has the advantages of large bearing capacity, good reliability, large linear displacement, flexible corner and consistent rotation performance in all directions. At the same time, it has a wide range of temperature applications, good durability and long service life, so it is increasingly widely used in various Class roads, railways, urban bridges and building structures. [0003] Like the traditional plate-type and basin-type rubber bearings, t...

Problems solved by technology

[0006] The lack of force measurement function makes it impossible to intuitively and conveniently detect and track the force state of the support cluster for a long time during the installation and operation process, and then cannot analyze and judge the force state of the superstructure, which is not conducive to timely and dynamic monitoring of the health status of the bridge structure. Monitoring and evaluation; it is difficult to measure the actual vertical load value of the support in real time and multiple times in a number of special working conditions, key nodes or abnormal conditions in the construction operation, and further analyze the actual internal force of each section of the superstructure Therefore, it is difficult to visually verify and evaluate the rationality of the design scheme and the stress state, safety and reliability of the actual structure

[0007] 2) The traditional spherical bearing structure does not have the force adjustment function

For the force adjustment of the existing traditional support of the current beam body, it is mainly realized by jacking up the beam body and adding single-layer or multi-layer thin steel plates to realize the external auxiliary height-adjusting support method, which is time-consuming and laborious, and needs to interrupt the current situation transportation
