[0002] In view of the domestic and international development trends and major technical requirements of urban three-dimensional transportation corridors, the scale and complexity of its projects are also constantly expanding, and the construction risks and operation and maintenance problems faced will become increasingly prominent. The existing public patent (announcement number is CN 113218343 B) discloses a deformation monitoring device for the roadbed under an existing viaduct, which belongs to the field of municipal construction technology, including deformation monitoring components respectively arranged at the four corners and the middle of the roadbed, the deformation monitoring component includes a connecting base plate, an inner rod and an outer sleeve, the connecting base plate is fixed to the roadbed, the inner rod is fixedly connected to the connecting base plate, the outer sleeve is arranged on the outside of the inner rod, the lower end of the outer sleeve is fixed to the compacted layer of the ground, the outer sleeve and the inner rod are sealed, and a displacement monitor is arranged in the outer sleeve, the displacement monitor is connected to a computer, and the displacement detector is used to monitor the deformation of the four corners and the middle of the roadbed. The device of the present invention can observe the collapse of the roadbed under the existing viaduct, and take necessary measures in time according to the collapse situation, so as to prevent further harm.

[0003] The above detection device directly monitors the roadbed, and its monitoring principle and the setting of the monitoring device are relatively cumbersome, which is not as efficient as directly monitoring the displacement change of the viaduct foundation column. To this end, we provide an viaduct displacement monitoring device to solve the above problems. Utility Model Content

[0005] The utility model discloses an elevated bridge displacement monitoring device, comprising an elastic touch switch, wherein the elastic touch switch comprises a base, a receiving portion integrally arranged on the upper part of the base, a reinforcing member fixed at the middle position of the receiving portion, an ear seat fixed at the middle position of the reinforcing member, a connecting rod movably arranged on the upper part of the ear seat, a plug-in matched with the upper end of the connecting rod, an end seat 1 movably matched with one end of the plug-in, and an end seat 2 matched with a branch at the lower part of the plug-in.

[0006] The utility model is further configured such that the end of the plug-in is inserted into a reserved hole of the elevated bridge, and the lower branch of the plug-in cooperates with two built-in contacts of the end seat.

[0007] The utility model is further configured that a spring is sleeved on the outside of the connecting rod, and a hook at the end of the spring matches the ear seat and the middle plug hole of the plug-in.

[0008] The utility model is further configured that the first end seat and the second end seat are threadedly fixed to the upper end of the receiving portion, and the interior of the receiving portion is a cavity structure.

[0009] The utility model is further configured that the edges of the two upper side surfaces of the end seat are arranged on the notch, and the end of the plug-in is inserted into the notch.

[0010] The utility model is further configured such that the upper end of the first end seat is closed, and the upper end of the second end seat is open.

[0011] The utility model has the following beneficial effects:

[0012] The utility model uses an elastic touch switch to assist in the displacement monitoring of the elevated bridge. It has a simple structure and is easy to install. It uses pressure sensing to monitor the displacement of the bridge. The implementation method is simple and efficient, and has great practical value.

[0013] The pressure generated when the lower branch of the plug-in squeezes it is monitored, and the displacement of the plug-in is judged according to the change in pressure, which further assists in judging the position of the elevated bridge. When the plug-in is subjected to instantaneous pressure, it moves downward, and when the pressure disappears, it returns to its initial position under the elastic action of the spring.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
