Description

Technical Field

[0001] This utility model relates to the field of tunnel operation safety technology, specifically a tunnel operation safety monitoring device. Background Technology

[0002] With the rapid development of urbanization and transportation infrastructure, the scale of tunnel engineering is constantly expanding, but its operational safety issues are becoming increasingly prominent. Tunnel structures are subject to long-term effects from geological activity, vehicle vibration, temperature and humidity changes, and corrosive gases, which can easily lead to accidents such as crack propagation, settlement deformation, gas leakage, and even collapse.

[0003] During the process of monitoring tunnel operation safety, it is necessary to monitor and handle the settlement of the tunnel roof. During the detection process, when the settlement inside the tunnel exceeds the limit, the monitoring device only issues an early warning for the settled part, and then waits for the construction personnel to inspect and repair it. This means that it cannot respond quickly and compensate for the settled part in a timely manner, thereby increasing the danger of the tunnel during operation. Utility Model Content

[0004] The purpose of this invention is to provide a tunnel operation safety monitoring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a tunnel operation safety monitoring device, including mounting plates on both sides, and a settlement support mechanism is provided on one side of each of the two mounting plates.

[0006] The settlement support mechanism includes a support assembly and a rebound assembly. The support assembly includes a first support plate disposed on one side of two mounting plates. A support frame is fixedly connected to one side of each of the two first support plates. A top plate is fixedly connected to the other side of each of the two support frames. A first fixing seat is fixedly connected to one side of the bottom of each of the two top plates. A first connecting rod is rotatably connected to one side of each of the two first fixing seats. The other end of the first connecting rod is rotatably connected to one side of two of the second fixing seats. A second connecting rod is rotatably connected to one side of the other two second fixing seats. A third fixing seat is rotatably connected to the other end of each of the two second connecting rods. A base plate is fixedly connected to the top of each of the two third fixing seats.

[0007] In one example, a second support plate is fixedly connected to one side of each of the two mounting plates. Grooves are provided on both sides of the top of the second support plate. A first slide rod is fixedly connected to the inner wall of each groove. A first slider is slidably connected to the outer wall of each first slide rod. The top of the first slider is fixedly connected to the bottom of the second fixed seat. A first spring is sleeved on the outer wall of each first slide rod.

[0008] In one example, two grooves are provided on the other side of each of the two support frames, and a second slider is slidably connected to the inner wall of each groove. The other end of the second slider is fixedly connected to one side of the base plate. Multiple support rods are fixedly connected to the top of each of the two base plates, and an arc-shaped plate is fixedly connected to the top of each support rod.

[0009] In one example, the rebound assembly includes two slots formed on one side of two mounting plates, each slot having a fixing block slidably connected to its inner wall, and the fixing block being fixedly connected to one side of a first support plate.

[0010] In one example, a third connecting rod is fixedly connected to both sides of the bottom of the two first support plates, and the other end of the third connecting rod is inserted into the top of the second support plate. A second spring is sleeved on the outer wall of each third connecting rod.

[0011] In one example, a monitoring device is fixedly connected to one side of the bottom of both second support plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This device is installed on the inner wall of the tunnel via a mounting plate. A support frame is provided on one side of the mounting plate via a first support plate. The support frame is in contact with the top of the tunnel. When the top of the tunnel settles, the support frame will also sink. During the sinking process of the support frame, the first connecting rod on one side of the first fixed seat will push the second fixed seat at the bottom forward. The bottom of the second fixed seat is provided with a first slider, which is connected to the groove on the top of the second support plate via a first sliding rod. The outer walls of the two first sliding rods are fitted with first springs. Under normal conditions, the first springs are in a free state. When the top of the tunnel settles, the first springs will be in a tensile state. This is to facilitate quick rebound after maintenance and to provide tighter support during the support process. Furthermore, a second connecting rod is provided on one side of the other two second fixed seats. The other end of the second connecting rod is provided with a base plate via a third fixed seat. The base plate will also rise under the action of the second connecting rod, thereby supporting the top of the tunnel and preventing the falling of gravel, thus improving safety during vehicle operation.

[0014] 2. The fixing block on one side of the first support plate is slidably connected to one side of the mounting plate. The bottom of the first support plate is provided with a third connecting rod, and a second spring is sleeved on the outside of the third connecting rod. The presence of the second spring is to assist the top support frame to rebound when the maintenance is completed, and then monitor the situation inside the tunnel. Attached Figure Description
