Description

Technical Field

[0001] This utility model relates to the field of road and bridge inspection technology, specifically a road and bridge settlement and deformation detection device. Background Technology

[0002] Settlement deformation is one of the important factors affecting structural safety and service life during the construction and maintenance of roads and bridges.

[0003] For example, patent publication number "CN220649474U", entitled "A Road and Bridge Settlement Deformation Detection Device", involves pressing down the detection plate, which in turn presses down the telescopic rod. The synchronous pressing down of the telescopic rod causes the display rod to move inside the housing, thus moving the display rod out of the third groove to detect the distance of road and bridge settlement. At the same time, when local deformation occurs in the road and bridge, it causes the local measuring block and the sliding rod to press down, so that the first and second scales can detect the magnitude of the local deformation of the road and bridge, thereby making the detection results of this utility model more accurate.

[0004] The aforementioned device detects road and bridge settlement by pressing down on the telescopic rod. However, since the mounting base and the telescopic rod are positioned vertically, the device can only detect road and bridge settlement in the vertical direction and does not support settlement deformation detection over long spans. Therefore, a road and bridge settlement deformation detection device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a road and bridge settlement and deformation detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a road and bridge settlement deformation detection device, the detection device comprising:

[0011] The detection tube is installed on the moving end of the connecting component;

[0012] The piston has its outer wall slidably connected to the inner wall of the detection tube.

[0013] A displacement detector is installed between the detection tube and the piston to detect the position of the piston inside the detection tube.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This road and bridge settlement deformation detection device has a connecting component installed between two fixed parts. The two connecting pipes are interconnected by a flexible hose, which enables settlement deformation detection over long distances. The displacement detector accurately measures the position change of the piston in the detection pipe and then analyzes the height difference of the liquid level in the two detection pipes to achieve accurate detection of settlement deformation of long-span bridges.

The control terminal controls the No. 1 motor to start according to the tilt angle, adjusting the connector to a horizontal state, thereby ensuring the normal use of the connecting components.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-3 As shown, this utility model provides a technical solution: a road and bridge settlement deformation detection device, the detection device comprising:

[0029] Fastener 1;

[0030] Connecting component 2 is installed inside the fixing component 1;

[0031] Connectivity component 2 includes:

[0032] A connecting component, used to keep the connecting component 2 horizontal, is mounted on one side of the fixing component 1;

[0033] Detection tube 201 is installed on the moving end of the connecting component;

[0034] Piston 202, the outer wall of piston 202 and the inner wall of detection tube 201 are slidably connected;

[0035] A displacement detector 203 is installed between the detection tube 201 and the piston 202 to detect the position of the piston 202 inside the detection tube 201.

[0036] The bottom end of the detection tube 201 is fixedly connected to the connecting tube 204, and one end of the connecting tube 204 is fixedly connected to the flexible tube 209.

[0037] The connecting assembly includes a connector 205, one end of which is rotatably connected to one side of the fixing member 1, one end of the detection tube 201 is fixed to the bottom end of the connector 205, and a leveling device for keeping the connector 205 in a horizontal state is installed between the connector 205 and the fixing member 1.

[0038] The leveling device includes an electronic level 206, one end of a connector 205 is fixed to one end of the electronic level 206, and a motor 207 is fixedly connected inside the fixing member 1. The output end of the motor 207 is fixed to one end of the connector 205.

[0039] The internal fixed connection of the fastener 1 includes the control terminal 208, the electronic level 206, and the control terminal 208 being electrically connected.

[0040] A connecting rope 4 is fixedly connected to the outer wall of the connecting pipe 204, and the top end of the connecting rope 4 is fixed to the bottom end of the bridge.

[0041] A pressure detector 3 for detecting the internal air pressure of the detection tube 201 is installed between the detection tube 201 and the piston 202. An air pump for controlling the internal air pressure of the detection tube 201 is installed inside the detection tube 201.

[0042] Fixing components 1 are installed at the bottom of the base and the bridge respectively. A connecting component 2 is installed between the two fixing components 1 to detect the settlement deformation of the road and bridge. The detection device is installed between the base and the bridge. The real-time monitoring of the settlement deformation of the bridge is achieved by stabilizing the base. When the bridge settles and deforms, the fixing component 1 may tilt. A leveling device is used to ensure that the connecting component 205 and the detection tube 201 are in a horizontal state so that the connecting component 2 can be used. When the connecting component 205 tilts due to the settlement of the bridge, the electronic level 206 detects and obtains the tilt angle and inputs the tilt angle into the control terminal 208. The control terminal 208 controls the start of the first motor 207, thereby causing the connecting component 205 to rotate to correct the tilt angle.

[0043] The two connecting pipes 204 are interconnected by a flexible hose 209. Considering that the settlement and deformation of the road and bridge will change the position and angle of the actual device, the flexible hose 209 is used to connect the two connecting pipes 204 in order to ensure that the connecting component 2 can be used normally, thereby avoiding damage to the adjacent device caused by the position and angle of the actual device.

[0044] Considering that the detection device is used in the outside environment, the outside temperature will affect the use of the connecting component 2. Therefore, a pressure detector 3 is used to detect the internal pressure of the detection tube 201, and an air pump is used to control the internal pressure of the detection tube 201 to ensure that the pressure detection values ​​in the two detection tubes 201 are consistent. A displacement detector 203 is used to detect the position between the detection tube 201 and the piston 202, thereby detecting the liquid level in the detection tube 201. By analyzing the height difference of the liquid level in the two detection tubes 201, the settlement deformation of the bridge can be detected, with the detection tube 201 located on the base as the reference.

[0045] The connecting pipe 204 is connected by a connecting rope 4 to effectively support the long-span connecting pipe 204, thereby ensuring that the connecting component 2 can detect the position of the long-span bridge. The connecting component 2 is installed between the two fixing parts 1, and the two connecting pipes 204 are interconnected by a hose 209, so that settlement deformation detection can be carried out over long distances. The displacement detector 203 accurately measures the position change of the piston 202 in the detection pipe 201, and then analyzes the height difference of the liquid level in the two detection pipes 201 to achieve accurate detection of settlement deformation of the long span of the bridge. With the setting of the leveling device, using an electronic level 206 and a first motor 207, when the bridge settlement causes the fixing part 1 to tilt, the electronic level 206 can detect the tilt angle in real time and transmit the data to the control terminal 208. The control terminal 208 controls the first motor 207 to start according to the tilt angle, and adjusts the connecting part 205 to a horizontal state, thereby ensuring the normal use of the connecting component 2.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
