Description

Technical Field

[0001] The utility model relates to the technical field of bridge monitoring, and more specifically, to a bridge deformation monitoring device. Background Art

[0002] The static level is a precision instrument for measuring height difference and its changes. It is mainly used for monitoring vertical displacement and inclination of pipeline corridors, dams, nuclear power plants, high-rise buildings, foundation pits, tunnels, bridges, subways, etc. The static level is generally installed on the measuring pier of the same height as the measured object or on the wall contour of the measured object. Usually, the data is automatically collected and stored in the field collection system through the built-in stand-alone collection software of the field collection box, and then connected to the Internet through wired or wireless communication and transmitted to the background network software, so as to realize automatic observation.

[0003] Since the static level needs to be installed on the same plane as the reference surface, the required installation accuracy is relatively high. The existing method for installing the static level is to manually position the static level through measurement and then fix it. The operation is cumbersome and the work efficiency is low. Utility Model Content

[0006] By adopting the above technical solution, the static level is installed on the fixed plate. When the position and angle of the static level need to be adjusted, the staff needs to start the stepper motor by pressing an external switch, so that the stepper motor drives the first gear to rotate on the mounting frame. After the first gear rotates, it can drive the second gear to rotate, and the fixed block on the second gear and the static level rotate accordingly. When the static level rotates to the position corresponding to the bridge, the staff turns off the stepper motor, so that the static level is fixed and no longer rotates. Then, the bridge can be monitored by the static level, which is convenient for the staff to operate, simple to operate, and improves the installation efficiency of the static level. The stepper motor has the advantages of high precision and long life, is suitable for long-term operation outdoors, and improves the efficiency of adjusting the angle of the static level.

[0008] By adopting the above technical solution, the setting of the motor protection cover can protect the stepper motor and prevent the stepper motor from being exposed to the outside world and being affected by weather or dust, which may cause damage to the stepper motor.

[0009] The utility model is further configured as follows: connecting plates are arranged on all four sides of the motor protection cover, a first threaded hole is arranged on the connecting plate, a second threaded hole is arranged on the mounting frame, and threaded rods are rotatably connected in the first threaded hole and the second threaded hole.

[0010] By adopting the above technical solution, when the stepper motor needs to be repaired, the staff can rotate the threaded rod so that the threaded rod is gradually rotated out of the first threaded hole and the second threaded hole, thereby realizing the removal of the motor protection cover, so that the staff can repair or otherwise handle the stepper motor in time, and it is also convenient for the staff to continue to cover the motor protection cover on the stepper motor to protect the stepper motor. The structure is simple and convenient for the staff to operate.

[0011] The utility model is further configured as follows: the static level is fixed on the fixing block by a first screw.

[0012] By adopting the above technical solution, the static level is fixed to the fixed block by the first screw, which can ensure the fixing force of the static level after adjustment, ensure the stability of the static level during use, and also facilitate the disassembly of the static level, so that the static level can be removed from the fixed block and replaced with a new one when damaged.

[0013] The utility model is further configured as follows: the static level is fixedly connected to the mounting frame by a second screw, the mounting frame is provided with a plurality of third threaded holes for the second screw to be inserted, and the paths in which the plurality of third threaded holes are arranged are consistent with the rotation path of the static level under the action of the angle adjustment device.

[0014] By adopting the above technical solution, after the static level is corrected, the staff aligns the second screw with the corresponding third threaded hole, and then rotates the second screw to transfer the second screw into the third threaded hole, thereby fixing the static level. This also facilitates the staff's operation and ensures the fixing strength of the static level.

[0015] The utility model is further configured as follows: a plurality of connecting plates are protrudingly arranged on the outer side of the static level, and a plurality of the connecting plates are provided with through holes for the second screws to be screwed into.

[0016] By adopting the above technical solution, when the static level is fixed on the mounting frame, several connecting plates on the outside of the static level can pass through the second screw, so that the static level can be easily fixed on the mounting frame and removed from the mounting frame, thereby improving the operating efficiency of the staff.

[0017] The utility model is further configured as follows: a transparent protective cover is sleeved on the mounting frame.

[0018] By adopting the above technical solution, the transparent protective cover is used to cover the mounting frame to protect the entire structure and facilitate the staff to observe the internal situation.

[0019] In summary, the utility model has the following beneficial effects: the mounting plate is first mounted on the bridge, and then the position of the static level body is adjusted under the action of the angle adjustment device, and the operation is relatively simple, thereby improving the installation efficiency of the static level.
