Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a bridge support state monitoring instrument. Background Art

[0002] Bridge bearings are important components for transferring loads, coordinating structural deformation, and ensuring structural safety between the upper and lower structures of bridges. Damage or destruction of bridge bearings will directly cause force deviation or imbalance of the upper and lower structures of bridges, which will in turn cause damage and destruction of other components, accelerate the decay of bridge life, and directly threaten the overall safety of bridge structures. With the development of economy and the increase of traffic volume, damage or destruction of bridge bearings has become one of the main diseases of bridges in service in my country.

[0003] As the main force-transmitting component between the superstructure and substructure of the bridge structure, the parameters such as force and strain of the bridge bearing will undergo significant changes. The changing patterns of parameters such as force and strain of the bearing can largely reflect the overall damage of the bridge. Therefore, strengthening the health monitoring of bridge bearings plays an important role in evaluating the overall safety of the bridge.

[0004] At present, many beam-falling diseases are caused by excessive bridge displacement or displacement deviation accumulated over many years. Regular manual inspection is a common means to obtain the health status of bridge bearings. However, mountainous areas and high piers are not conducive to manual inspection and maintenance of bearings. At the same time, bridge bearings are generally in harsh and hidden engineering environments. Manual inspection methods have certain limitations, which can easily lead to many diseases not being discovered and handled in a timely manner.

[0005] Therefore, it is necessary to provide a bridge bearing condition monitor to solve the above technical problems. Utility Model Content

[0040] In the embodiments of the present invention, reference is made to Figure 3 As shown, a plurality of distance measuring slots 15 are provided on the top of the support base 1 , and the third infrared rangefinder 16 is installed in the distance measuring slots 15 .

[0041] The working principle of a bridge bearing condition monitoring device provided by the utility model is as follows:

[0042] When in use, the bottom of the support seat 1 can be installed on the ground where the bridge bearing is located, and the bridge bearing is located on the inner side of the support seat 1, or the support seat 1 can be floated on the water surface where the bridge bearing is located through a corresponding fixing mechanism, that is, the first electric slide rail 3 and the second electric slide rail 19 are located on both sides of the bridge bearing. When measuring, the first electric slide rail 3 and the second electric slide rail 19 can be driven to drive the corresponding third electric slide rail 5 and the fourth slide block to move forward and backward, and the corresponding first infrared rangefinder 22 and the second infrared rangefinder 8 can be moved forward and backward.

[0043] Length measurement:

[0044] Start moving from one end of the first electric slide rail 3 or the second electric slide rail 19, and emit infrared rays to the bridge support through the first infrared rangefinder 22 or the second infrared rangefinder 8 during the movement. When the first infrared rangefinder 22 or the second infrared rangefinder 8 receives the reflected infrared rays, the corresponding first displacement sensor 17 or the second displacement sensor 23 starts to work and records the moving distance until the first infrared rangefinder 22 or the second infrared rangefinder 8 can no longer receive the reflected infrared rays, then stops recording. At this time, the distance recorded by the first displacement sensor 17 or the second displacement sensor 23 is the length of the bridge support;

[0045] Width measurement:

[0046] Since the first electric slide rail 3 and the second electric slide rail 19 are arranged in parallel, when they are on the same vertical plane, the distance between the first infrared rangefinder 22 and the second infrared rangefinder 8 is fixed. The first infrared rangefinder 22 and the second infrared rangefinder 8 can be moved to the same vertical plane through the first electric slide rail 3 and the second electric slide rail 19, and then the first infrared rangefinder 22 and the second infrared rangefinder 8 simultaneously emit infrared rays to the bridge support. When the first infrared rangefinder 22 and the second infrared rangefinder 8 receive the reflected infrared rays, the distances between the first infrared rangefinder 22 and the second infrared rangefinder 8 and the bridge support are obtained. The width of the bridge support can be obtained by subtracting the distances between the first infrared rangefinder 22 and the second infrared rangefinder 8 from the distances between the corresponding rangefinders and the bridge support.

[0047] Height measurement:

[0048] The third infrared rangefinder 16 emits infrared rays upward and receives reflected infrared rays, thereby measuring the distance between the third infrared rangefinder 16 and the bottom of the bridge. Since the third infrared rangefinder 16 is installed on the top of the support seat 1, that is, the height of the third infrared rangefinder 16 is fixed, the height of the bridge support can be obtained by adding the distance between the third infrared rangefinder 16 and the bottom of the bridge to the height of the third infrared rangefinder 16.

[0049] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0050] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
