Shock-absorbing and buffering assembly of bridge and monitoring system

Abstract

The invention provides a shock-absorbing and buffering assembly of a bridge and a monitoring system. The shock-absorbing and buffering assembly of the bridge comprises L-shaped sliding tracks arranged under the bridge, I-shaped steel arranged between the L-shaped sliding tracks, a curved surface arranged on the I-shaped steel, a slider arranged on and cooperating with the curved surface, a base sleeved on the lower part of the I-shaped steel, a track mechanism arranged at the bottom surface of the bridge and a detecting machanism arranged on the track mechanism and used for detecting the actual situation of the bottom surface of the bridge, wherein the L-shaped sliding tracks are connected with the base through springs. The shock-absorbing and buffering assembly of the bridge and the monitoring system have the advantages of realizing the laying of the detecting mechanism from a main track to a secondary track, ensuring the full-scale starting of monitoring tests, avoiding the phenomenon of long detection periods, achieving quick comparison and analysis by sending acquired data and information back to a central control room and finding problems of the bottom of the bridge by the quick comparison.

Description

technical field [0001] The invention relates to the technical field of bridge detection devices, in particular to a bridge shock absorbing and buffering component and a monitoring system. Background technique [0002] Long-span bridges are major transportation infrastructure projects. In order to reduce secondary disasters after earthquakes and ensure the safety of traffic lifelines, their seismic safety cannot be underestimated. With the implementation of my country's western resource development strategy and the "One Belt, One Road" national strategy, the construction of long-span bridges in high-intensity earthquake areas and active fault areas has become an inevitable and realistic demand. A lot of practice has proved that adopting proper seismic reduction and isolation design is an effective method to improve the seismic performance of long-span bridges. , can significantly reduce the inertial force transmitted to the substructure, and realize the mutual balance betwee...

Problems solved by technology

At present, the commonly used equipment for bridge deformation monitoring are: conventional ground measurement equipment, GPS bridge displacement detection equipment, and radar deformation measurement equipment; Timely response and treatment will result in huge property losses and heavy casualties, so we need to monitor the deformation of the bridge in real time to achieve the purpose of early treatment

[0004] A real-time monitoring system for bridge deformation is disclosed in the publication number CN 105890663 A. The invention includes a monitoring room and a bridge deck; the bottom of the bridge deck is connected with a bridge deck support beam; the two ends of the bridge deck support beam bottom are connected with bridge piers; One side of the bridge deck is equipped with bridge deck monitoring point sensors; the monitoring room is associated with the bridge deck monitoring point sensors; both sides of the bridge deck are provided with flanges; the flanges are in a horizontal state; the inside of the monitoring room is equipped with a data processor; An evaluation worker is set on one side of the data processor; the top surface of the evaluation worker is connected to a console; bridge monitoring point sensors are set at both ends of the front of the bridge deck support beam; bridge pier monitoring point sensors are set on the side of the bridge pier near the bottom ;The side of the other pier near the bottom is equipped with a displacement gauge; although this structure has obtained a good detection effect, it cannot detect the interior and all-round detection, which makes it prone to mistakes

[0005] In the publication number CN 105973452 A, a remote bridge vibration monitoring system includes a laser transmitter, an optical fiber coupler, an optical fiber, a stepping motor, a plane mirror, an optical fiber collimator, a photoelectric detector and a signal transmission module, and a laser transmitter The emitted laser light is dispersed into multiple laser beams after passing through the fiber coupler. The first laser beam is irradiated on the rotatable plane mirror through the optical fiber, and the laser beam is reflected on the plane mirror. The laser light is sent to multiple photodetectors respectively through the optical fiber; the photodetector also receives the scattered signal of the laser light on the bottom surface of the bridge and sends the signal together with the laser signal received from the optical fiber to the signal sending module; To obtain the information of the bridge, but it has not realized the all-round detection of the bridge, so it is also prone to mistakes.
