Description

Technical Field

[0001] The utility model relates to the technical field of settlement deformation detection, in particular to a settlement deformation detection device. Background Art

[0002] Road bridges generally refer to structures erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other traffic needs to make passage more convenient. The settlement deformation of road bridges is the vertical deformation or sinking of the foundation soil caused by compression under the action of load. When the settlement is too large, the elevation of the road bridge will be reduced and its use will be affected; while uneven settlement is more harmful to road bridges, causing additional stress on the road bridge and causing cracks, or even local component fractures, endangering the safety of road bridges and moving vehicles. Therefore, settlement deformation detection devices are needed to frequently detect road bridges.

[0003] For example, a road bridge settlement deformation detection device according to Chinese patent application number CN202322447027.2 includes a storage seat, a telescopic rod is movably connected to the top of the storage seat, the telescopic rod is fixedly connected to a control panel away from the top of the storage seat, and limiting grooves are arranged around the control panel. A detection plate is fixedly connected to the top of the control panel. When the road bridge settles, the detection plate will be pressed down, and the telescopic rod will be pressed down accordingly by the downward pressure of the detection plate. After the telescopic rod is pressed down synchronously, the display rod will move inside the storage seat, so that the display rod moves out of the third groove to detect the settlement distance of the road bridge. At the same time, when the road bridge is locally deformed, the local measuring block and the lower sliding rod are driven to be pressed down, so that the first scale and the second scale form a detection of the size of the local deformation of the road bridge, thereby making the result of the road bridge detection of the utility model more accurate.

[0004] However, in actual use, the above-mentioned device can only monitor the local settlement and deformation of roads and bridges, which not only reduces the detection efficiency but also has limitations. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-6 As shown, the utility model provides a settlement deformation detection device, which is installed on a road bridge body 3, wherein the road bridge body 3 is arranged on the top of two roadbeds 1, and a plurality of piers 2 are arranged between the two roadbeds 1 and the bottom of the road bridge body 3;

[0027] like Figure 1-4As shown, a settlement detection assembly 4 is provided between the several piers 2 for detecting the settlement deformation of the road bridge body 3. The settlement detection assembly 4 comprises a left fixing ring 41 and a right fixing ring 42. The left fixing ring 41 and the right fixing ring 42 are respectively clamped on both sides of the pier 2. A fixing pile 44 is fixedly provided on one side of the right fixing ring 42. A rotating shaft 46 is connected to the top of the fixing pile 44 through a bearing. A detection platform 47 is fixedly provided on the top of the rotating shaft 46. A first ultrasonic transmitter 48 and a first ultrasonic receiver 49 are respectively fixedly provided on both sides of the detection platform 47.

[0028] The intersections of the left fixing ring 41 and the right fixing ring 42 are both threadedly connected with bolts for fixing the left fixing ring 41, the right fixing ring 42 and the pier 2, so as to facilitate adjustment of the positions of the left fixing ring 41 and the right fixing ring 42 on the pier 2, and facilitate disassembly, so as to timely repair the first ultrasonic transmitter 48 and the first ultrasonic receiver 49. A motor 45 is fixedly arranged inside the fixing pile 44, and the output shaft of the motor 45 passes through the fixing pile 44 and is fixedly connected to the bottom end of the rotating shaft 46, so as to facilitate the operation of the motor 45 to drive the rotating shaft 46 to rotate and drive the detection platform 47 on the top thereof to rotate.

[0029] like Figure 1 , 2 As shown in , 5 and 6, it includes an inclination detection component 5 fixed on the top of the two roadbed seats 1, which is used to realize inclination deformation detection of the road bridge body 3. The inclination detection component 5 includes two fixed seats 51, and the two fixed seats 51 are respectively fixed at the top center of the roadbed seat 1. A connecting rod 52 is fixed on the top of the two fixed seats 51, and a fixing platform 53 is fixed on the top of the two connecting rods 52. A second ultrasonic transmitter 54 and a second ultrasonic receiver 55 are respectively fixed on opposite sides of the two fixing platforms 53, so as to facilitate the detection of the inclination deformation data of the pier 2. The first ultrasonic receiver 49 receives the signal emitted by the first ultrasonic transmitter 48, and the second ultrasonic receiver 55 receives the signal emitted by the second ultrasonic transmitter 54, so as to facilitate the detection of settlement and inclination deformation data of the pier 2.

[0030] By setting a settlement detection component 4 and a tilt detection component 5, a plurality of left fixing rings 41 and right fixing rings 42 are mutually clamped on the pier 2, and the positions of the left fixing ring 41 and the right fixing ring 42 are fixed by two bolts 43, and then the motor 45 is driven to drive the rotating shaft 46 to rotate and drive the detection platform 47 to rotate, and the first ultrasonic transmitter 48 transmits ultrasonic waves to the first ultrasonic receiver 49, and then the distance between the ultrasonic transmitter and the ultrasonic receiver is calculated in combination with the time when the ultrasonic waves are emitted and the time when they are received, so as to calculate the settlement deformation data of the road bridge according to the change of the distance data;

[0031] Similarly, ultrasonic waves are emitted from the second ultrasonic transmitter 54 to the second ultrasonic receiver 55, and then the distance between the ultrasonic transmitter and the ultrasonic receiver is calculated based on the time when the ultrasonic wave is emitted and the time when it is received, thereby calculating the inclination deformation data of the road bridge according to the change in distance data, and then by performing comprehensive detection of the road bridge, the detection effect and accuracy are improved, and the continuity of the detection data is ensured.

[0032] With the development of road and bridge inspection work, there are two ways to monitor the settlement and deformation of the road and bridge body 3: one is to realize the detection through the interaction of the fixed platform 53 and the second ultrasonic transmitter 54; the other is to realize the detection through the interaction of a plurality of first ultrasonic transmitters 48 and first ultrasonic receivers 49; the functions are as follows: the fixed platform 53 and the second ultrasonic transmitter 54 are the transition before the first ultrasonic transmitter 48 and the first ultrasonic receiver 49 are put into operation. When the first ultrasonic transmitter 48 and the first ultrasonic receiver 49 are used normally, the fixed platform 53 and the second ultrasonic transmitter 54 will no longer be used. At the same time, after the first ultrasonic transmitter 48 and the first ultrasonic receiver 49 are damaged, the fixed platform 53 and the second ultrasonic transmitter 54 can be used to re-detect the road and bridge body 3, thereby ensuring the continuity of the detection data, and the positions of the left fixed ring 41 and the right fixed ring 42 on the pier 2 are about 1m above the ground or water surface, so as to detect the settlement and lateral inclination of the pier 2, and the elevation difference between the two piers 2 is used to transmit the elevation, thereby ensuring the continuity of the monitoring data of each cycle.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
