Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bridge engineering, and in particular to a bridge sensor installation structure. Background Art
[0002] The expansion joint of a bridge is an indispensable part of the bridge structure. If the design is unreasonable, the construction quality does not meet the standards, and the maintenance method is unscientific, these will cause varying degrees of damage to the expansion device of the bridge, resulting in height differences between the beams on both sides of the expansion joint, resulting in cracks in the road surface, and vehicles will jump and impact when passing, thereby causing additional impact loads on the bridge and the road surface, and making drivers feel uncomfortable. Severe cases may cause traffic accidents, thus affecting the normal life and operation of highway bridges. In order to meet the requirements of deformation and longitudinal displacement of the bridge superstructure, expansion joints are usually set between the two beam ends, between the beam end and the abutment, or at the hinged position of the bridge. Due to the great influence of temperature, concrete will expand and contract, which will cause the length of the beam to change. At the same time, under the action of vehicle loads, the length of the bridge beam will change and the lower structure will also settle.
[0003] At present, it is difficult to observe the expansion joints of bridges with the naked eye during the long-term use of bridges. If problems cannot be discovered in time during the long-term use of bridges, it will bring certain risks and serious losses to the use of the bridges. Utility Model Content

DETAILED DESCRIPTION
[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.
[0031] An embodiment of the present application discloses a bridge sensor installation structure.
[0032] Reference Figure 1 A bridge sensor installation structure includes an adjacent first bridge matrix 101 and a second bridge matrix 102, and includes two connectors 1. The ends of the two connectors 1 that are away from each other are fixedly connected with connecting plates 2, and expansion screws 21 are threadedly connected to the connecting plates 2. The two connecting plates 2 are respectively connected to the first bridge matrix 101 and the second bridge matrix 102 through the expansion screws 21. When the expansion joint between the first bridge matrix 101 and the second bridge matrix 102 becomes wider, the distance between the two connectors 1 is away from each other.
[0033] Reference Figure 1 and Figure 2 , detection plates 3 are installed on both connectors 1, and the detection plates 3 are detachably connected to the connector 1. A connecting groove 11 is provided on the side of the connector 1 away from the connecting plate 2. The detection plate 3 is located in the connecting groove 11 and is movably connected to the connector 1. A limiting component 4 for limiting the connection between the connector 1 and the detection plate 3 is provided in the connector 1. The limit assembly 4 includes a limit rod 41, a limit block 42 and an elastic spring 43. A limit groove 31 is provided on the side of the detection plate 3. A placement groove 12 connected to the connecting groove 11 is provided in the connecting body 1. The limit rod 41 is located in the placement groove 12 and is slidably connected to the connecting body 1. The elastic spring 43 is located in the placement groove 12. One end of the elastic spring 43 is fixedly connected to the end of the limit rod 41, and the other end of the elastic spring 43 is fixedly connected to the inner wall of the placement groove 12. The end of the limit rod 41 away from the elastic spring 43 is fixedly connected to the limit block 42. The end of the limit block 42 away from the limit rod 41 is provided with an inclined surface along the direction close to the notch of the connecting groove 11 to the direction away from the notch of the connecting groove 11. When the elastic spring 43 is in a natural state, the limit block 42 is located in the limit groove 31. During the process of moving the detection plate 3 into the placement groove 12 of the connector 1, the inclined surface of the limit block 42 abuts against the side wall of the detection plate 3, and the detection plate 3 continues to move into the placement groove 12, pushing the limit block 42 and the limit rod 41 into the placement groove 12, and the elastic spring 43 is compressed. When the limit groove 31 of the detection plate 3 corresponds to the placement groove 12, the compressed elastic spring 43 is released, pushing the limit rod 41 and the limit block 42 to move in the direction of the limit groove 31, so that the limit block 42 moves into the limit groove 31, and the detection plate 3 is connected to the connector 1.
[0034] Reference Figure 2A first rack 411 is installed on the top of the limit rod 41, and a connecting gear 5 is rotatably connected in the connecting body 1, and the connecting gear 5 is meshed with the first rack 411. A moving rod 6 is passed through the connecting body 1, and the moving rod 6 is movably connected to the connecting body 1. A moving block 61 is fixedly installed at the end of the moving rod 6 outside the connecting body 1, and the moving rod 6 is conveniently moved by the moving block 61. A second rack 62 meshed with the connecting gear 5 is installed on the side wall of the moving rod 6. By moving the moving rod 6 toward the connecting body 1, the connecting gear 5 is driven to rotate by the first rack 411, and the moving rod 6 is driven to move away from the limiting groove 31 by the second rack 62, so that the limiting block 42 is disengaged from the limiting groove 31. The two detection plates 3 often vibrate with the first bridge matrix 101 and the second bridge matrix 102, so that each component between the two detection plates 3 is prone to wear. The above structure is convenient for replacing each component between the two detection plates 3.
[0035] Reference Figure 1 and Figure 3 , a detection assembly 7 is arranged between the two detection plates 3, and the detection assembly 7 includes a first connecting tube 71, a second connecting tube 72 and a connecting rod 73. One end of the first connecting tube 71 is hinged to one of the detection plates 3, and the second connecting tube 72 is hinged to the other detection plate 3. The end of the first connecting tube 71 close to the second connecting tube 72 is rotatably connected to the connecting rod 73. The surface of the end of the connecting rod 73 away from the first connecting tube 71 is provided with an external thread, and the inner wall of the second connecting tube 72 is provided with an internal thread. The connecting rod 73 is threadedly connected to the second connecting tube 72, and a distance sensor 8 is arranged at the inner end of the connecting rod 73 located in the second connecting tube 72. When the expansion joint between the first bridge matrix 101 and the second bridge matrix 102 widens, the first connecting tube 71 and the second connecting tube 72 move away from each other, the connecting rod 73 rotates with the first connecting tube 71 and moves in a direction away from the second connecting tube 72, and the distance sensor 8 detects the distance to the bottom of the inner tube of the second connecting tube 72. Or when the first bridge matrix 101 and the second bridge matrix 102 are vibrated and misaligned, the first connecting tube 71 and the second connecting tube 72 are respectively hinged to the corresponding detection plate 3, the first connecting tube 71 and the second connecting tube 72 are tilted, and the distance between the first connecting tube 71 and the second connecting tube 72 is changed. The distance sensor 8 in the second connecting tube 72 performs real-time detection and timely detects the expansion joint of the bridge.
[0036] Reference Figure 1 and Figure 3 The surface of the connecting rod 73 is marked with a scale 731, and the second connecting tube 72 is extended to be installed with an indicating tube 721 sleeved outside the connecting rod 73. The scale 731 is convenient for observing the distance between the first connecting tube 71 and the second connecting tube 72, so as to judge the distance between the expansion joints.
[0037] Reference Figure 3and Figure 4 The distance sensor 8 is electrically connected to a comparison module 81. The distance sensor 8 sends a distance signal to the comparison module 81. The comparison module 81 responds to the distance signal and compares the distance signal with a preset reference value. When the distance signal is greater than the preset reference value, the comparison module 81 outputs an alarm signal. The detection board 3 is equipped with a power module 82 and an alarm module 83. The power module 82 is electrically connected to the distance sensor 8, the comparison module 81 and the alarm module 83. The comparison module 81 is electrically connected to the alarm module 83. The alarm module 83 responds to the alarm signal and gives an alarm. The distance sensor 8 detects the distance between the end of the connecting rod 73 and the bottom of the second connecting tube 72. The closer the distance, the smaller the distance signal value, and the farther the distance, the larger the distance signal value. When the first connecting tube 71 and the second connecting tube 72 move away from each other, the distance sensor 8 moves away from the second connecting tube 72. When the distance signal is greater than the preset reference value, the alarm module 83 gives an alarm to remind the staff to perform maintenance in time.
[0038] Among them, the alarm module 83 is an audible and visual alarm, which is convenient for the staff to locate the position of the device in time.
[0039] The implementation principle of a bridge sensor installation structure in an embodiment of the present application is as follows: the connecting plate 2 is connected to the first bridge matrix 101 and the second bridge matrix 102 by means of expansion screws 21. When the expansion joint between the first bridge matrix 101 and the second bridge matrix 102 becomes wider, the first connecting tube 71 and the second connecting tube 72 move away from each other, the connecting rod 73 rotates with the first connecting tube 71 and moves away from the second connecting tube 72, and the distance sensor 8 detects the distance to the bottom of the inner tube of the second connecting tube 72. When the first bridge matrix 101 and the second bridge matrix 102 vibrate and misalign, the first connecting tube 71 and the second connecting tube 72 are respectively hinged to the corresponding detection plate 3, and the first connecting tube 71 and the second connecting tube 72 are tilted, which also changes the distance between the first connecting tube 71 and the second connecting tube 72. The distance sensor 8 in the second connecting tube 72 performs real-time detection to detect the expansion joint of the bridge in time.
[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
