Description

Technical Field

[0001] The present invention relates to the technical field of bridge safety, and in particular to a vibration monitoring and early warning device and method for demolishing an old bridge. Background Art

[0002] As an indispensable part of modern road traffic, bridges carry a large number of vehicles and pedestrians. The safety of bridges is a very important matter concerning people's livelihood. In addition, there are many dangerous bridges and old bridges in the current road network. The overall bearing capacity of these bridges decreases with long-term use, cracks may appear inside the bridges, and the safety decreases. Therefore, when facing these problems, there are two main ways to deal with them: reinforcement and demolition. If the bridge is demolished, it is necessary to monitor and evaluate the bridge vibration and formulate a suitable demolition plan. By installing sensors and data acquisition equipment, the vibration generated by the bridge structure during the demolition process is recorded in real time, and these vibration data are analyzed and evaluated. The purpose of this monitoring is to ensure the safety and effectiveness of the bridge demolition process, and to promptly discover and deal with possible safety hazards.

[0003] Regarding the above-mentioned related technologies, the applicant believes that: currently, when monitoring the vibration of bridges, vibration sensors are generally installed at the bottom or a certain location outside the bridge for real-time monitoring. The monitored vibration frequency data is transmitted to the control platform for unified analysis, and early warning operations are performed based on the analysis results. However, the vibration monitored is local, not a large-scale bridge location, and the data source obtained is limited, which leads to deficiencies in the data analysis and evaluation of bridges.

[0004] To this end, the present invention provides a vibration monitoring and early warning device and method for old bridge demolition to solve the above problems. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a vibration monitoring and early warning device and method for old bridge demolition, which solves the above problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a vibration monitoring and early warning device and method for demolishing an old bridge, comprising a mobile box, a support assembly installed on the bottom wall of the mobile box, a placement assembly installed on the bottom of the front wall of the mobile box, a host console installed on the top of the mobile box via a lifting assembly, a display screen hingedly installed on the rear part of the top wall of the host console, an early warning sounder installed on the front part of the top wall of the host console, and an induction plate installed on the top wall of the host console and on the right side of the early warning sounder;

[0007] The placement assembly includes two placement racks, which are symmetrically arranged up and down. Two mounting grooves are provided at the bottom of the front wall of the mobile box. Limit slide grooves are provided on the inner walls of the two mounting grooves. Limit sliders are fixedly installed on the rear of the outer walls of the two placement racks and at the positions corresponding to the limit slide grooves. Placement grooves are provided on the top walls of the two placement racks. Protective pads are installed on the inner walls of the two placement slots.

[0008] Through the above technical solution, the placement component setting can be used to install and place the vibration sensor, which can be connected and used in conjunction with the host console when needed, thereby enabling vibration data monitoring of the old bridge on a larger scale.

[0009] Furthermore, the outer walls of the two placement racks are slidably connected to the inner walls of the corresponding mounting grooves, the outer walls of the two limit sliders are slidably connected to the inner walls of the corresponding limit slide grooves, the front walls of the two placement racks are fixedly installed with rubber pads, the outer walls of the two rubber pads are fit with the inner walls of the corresponding mounting grooves, the front walls of the two rubber pads are fixedly installed with handles, and the four corners of the top walls of several mounting seats are screwed with fastening bolts, several vibration sensors are electrically connected to the corresponding signal transmitters and sensing probes, and the outer walls of several sensing probes are fit with the corresponding inner walls of the through openings.

[0010] Through the above technical solution, the placement rack slides in the corresponding inner wall of the installation groove, and drives the limiting slider to slide in the corresponding inner wall of the limiting slide groove. At the same time, the rubber pad can increase the friction with the inner wall of the installation groove, which can prevent the placement rack from sliding outward when the mobile box is moved.

[0011] Furthermore, the support assembly includes two support plates, and an installation opening is opened on the bottom wall of the movable box. The two support plates are symmetrically arranged on the left and right, and both support plates are hingedly installed on the inner side wall of the installation opening. Support pads are fixedly installed on the adjacent sides of the two support plates.

[0012] Through the above technical solution, the support plate drives the support pad to prop up the mobile box to facilitate the staff to operate the host console.

[0013] Furthermore, the inner side walls of the installation opening are fixedly installed with magnet No. 1, and the top wall of the installation opening corresponding to the position of the support plate is fixedly installed with magnet No. 2, and the bottom walls of the two magnet No. 2 are in contact with the top wall of the support plate.

[0014] Through the above technical solution, when the support plate flips over and drives the support pad to contact the ground, the support plate is adsorbed and fixed to the No. 1 magnet.

[0015] Furthermore, the lifting assembly includes two limit blocks, which are arranged symmetrically on the left and right. The outer walls of the two limit blocks are fixedly connected to the outer walls of the host console. The top wall of the mobile box is provided with an installation cavity, and the inner wall of the installation cavity is slidably connected to the outer wall of the host console.

[0016] Through the above technical solution, the host console is mainly installed in the inner wall of the installation cavity and can be freely raised and lowered.

[0017] Furthermore, the inner side walls of the installation cavity are each provided with a limiting long groove, and the inner walls of the two limiting long grooves are both slidably connected to the outer walls of the corresponding limiting blocks.

[0018] Through the above technical solution, when the host console is raised or lowered, it will drive the limit block to slide in the inner wall of the corresponding limit long groove.

[0019] Furthermore, telescopic rods are fixedly installed at the four corners of the bottom wall of the installation cavity, the top ends of several telescopic rods are fixedly connected to the bottom wall of the host console, springs are installed on the outer walls of several telescopic rods, and downward pressure columns are fixedly installed at the four corners of the top wall of the host console.

[0020] Through the above technical solution, when the cover is closed, it will drive the down-pressing column and the host console to slide in the inner wall of the installation cavity, and compress the telescopic rod and the spring, so that the host console enters the inner wall of the installation cavity.

[0021] Furthermore, a cover plate is hingedly mounted on the rear portion of the top wall of the mobile box, a protective pad is fixedly mounted on the outer wall of the cover plate, and a handle is fixedly mounted on the rear wall of the cover plate.

[0022] Through the above technical solution, the protective pad is mainly used to protect the electronic components at the top of the host console.

[0023] Furthermore, a buckle is fixedly installed on the top wall of the cover plate, and a socket matching the buckle is fixedly installed on the front wall of the moving box.

[0024] Through the above technical solution, the cover plate can be sealed and fixed by the cooperation between the buckle and the socket.

[0025] A vibration monitoring and early warning method for old bridge demolition includes the following steps:

[0026] S1. Before dismantling the old bridge, perform vibration monitoring, turn the buckle to disengage it from the card holder, and then start to flip the cover to disengage it from the top wall of the mobile box. At the same time, the protective pad is disengaged from the contact with the host console. The spring and the telescopic rod are in a compressed state. When the cover is opened and no longer in contact with the lower pressure column, the elastic action of the spring pushes the telescopic rod to extend, and then pushes the host console to slide upward in the inner wall of the installation cavity, thereby driving the limit block to slide upward in the inner wall of the corresponding limit slot, flipping the display screen open and starting the host console to open.

[0027] S2. Flip the support plate downward to drive the support pad to rotate downward, so that the support plate is separated from the adsorption state of the second magnet and the support plate is separated from the mounting port. When the support plate and the support pad are flipped, the support plate is adsorbed and fixed by the first magnet, and the support pad is in contact with the ground for support, thereby driving the mobile box and the host console to be propped up, making it easier for the staff to operate and use;

[0028] S3, then pull the handle outward to drive the rubber pad to move outward, the rubber pad slides outward on the inner wall of the installation groove and drives the placement bracket to slide in the inner wall of the installation groove. When the installation groove slides, it drives the limit slider to slide outward in the corresponding inner wall of the limit slide groove, and the movable mounting seat drives the vibration sensor and the stud to move outward, so that the mounting seat is out of contact with the inner wall of the groove, and the sensing probe is out of contact with the inner wall of the through hole, and the vibration sensor is rotated to drive the stud to rotate and lock in the inner wall of the screw barrel to maintain the installation stability of the vibration sensor and the signal transmitter, start the vibration sensor to work formally and contact the signal transmitter with the sensing plate, and operate the information entry and signal connection of the vibration sensor through the host console, and after the information entry of the vibration sensor is completed and the signal connection is unobstructed, start to drive the mounting seat to be screwed to the external position of the old bridge by tightening the bolts, check the signal connection status of all vibration sensors after installation on the display screen through the host console, and test whether the host console can receive the data signal sent by the vibration sensor;

[0029] S4. Vibration sensors are evenly installed on the outer surface of the bridge. When the old bridge vibrates, the induction probe of the vibration sensor installed on the outer surface of the bridge senses the vibration and sends the vibration data to the signal input end of the host console through the signal transmitter. After receiving the signal, the host console will summarize and analyze the data and formulate a suitable plan for the demolition of the bridge to avoid safety hazards to a greater extent. When the vibration exceeds the safe range, the host console will control the early warning sounder to sound an alarm to warn the staff.
