Description

Technical Field

[0001] The invention relates to the technical field of bridge bearing detection, and in particular to a bridge bearing detection auxiliary device. Background Art

[0002] As an important load-bearing and weight-reducing component in the bridge structure, rubber bearings are responsible for connecting the upper structure and lower bearings of the bridge. Regular inspection of the status and performance of bridge rubber bearings is crucial to ensure the safety and stability of bridge operation. The main functions of bridge rubber bearing inspection include: evaluating the performance of rubber bearings. The main inspection methods include: ultrasonic inspection, vibration table test and thermal infrared inspection. Here, ultrasonic inspection technology is mainly used for rubber bearings of bridge bearings that have been installed and used to evaluate their quality and damage. It mainly uses the propagation speed of ultrasonic waves in the material and the change of echo signals for analysis. This non-destructive inspection technology can not only evaluate the physical properties of rubber bearings, but also provide detailed information about their structure and performance without affecting the normal use of rubber bearings. It is of great significance to ensure the safe operation of bridges.

[0003] The traditional inspection method is to use a lift to send staff to the vicinity of the bridge support and inspect the bridge support manually. In order to accommodate the inspection personnel, the size of the lift is large. Before the inspection, a vehicle of corresponding size is required to transport the lift to the bridge. The larger vehicle occupies the space used by the bridge, and during the inspection process, the inspection personnel and the elevator control personnel are required to communicate and cooperate with each other to ensure the smooth progress of the inspection. The whole process is time-consuming and affects the normal use of the bridge. In addition, it is difficult to inspect the back side manually during the inspection process, which further causes the inspection to take longer. Summary of the invention

[0015] It can be seen from the above technical solutions that the present invention has the following advantages:

[0016] 1. In the present invention, the center axis of the semicircular gear ring is aligned with the center axis of the adjacent bridge support by cooperating with the close-fitting frame 1 and the close-fitting frame 2, and the detection probe is moved to the surface of the rubber support, and the motor 4 drives the winding drum to rotate, thereby winding the wire rope and driving the detection probe to rotate 180° around the rubber support.

[0017] 2. In the present invention, the forces between the center column 1 and the connecting column 1 and between the center column 1 and the square column 1 are balanced by a balancing spring 1, and adaptive compensation is performed on the compensation column 1 and the connecting column 1 by a pair of cylindrical springs, so as to achieve the purpose of aligning the center of the alignment frame with the center of the support pad stone.

[0018] 3. In the present invention, by adjusting the horizontal position of the limit column during the horizontal movement of the isosceles triangle block, it is ensured that the distance between the connecting column 1 and the supporting pad stone and the distance between the connecting column 2 and the supporting pad stone are small, so as to prevent the alignment frame on either side from contacting the bridge support when the connecting column 1 and the connecting column 2 move horizontally toward the bridge support, thereby causing damage to the alignment frame.

[0019] 4. In the present invention, the distance between the inclined plates on the front and rear sides is adjusted by cooperating with the bidirectional screw rod 1 and the bidirectional screw rod 2, and the inclination angle of the inclined plates is adjusted at the same time, to ensure that when the square column 1 and the connecting column 1 move toward the bridge support together, the inclined plates first contact with the support pedestal stone, and the compensation column 2 and the connecting column 2 are adaptively compensated by the cylindrical spring 2, so as to achieve the purpose of aligning the center of the center column 1 with the center of the support pedestal stone.

[0020] 5. In the present invention, after the test probe performs a 180° test on the rubber bearing, if a more detailed test result is required, the sprocket one is driven to rotate by the motor three, and with the cooperation of the toothed chain belt one, the sprocket two and the sprocket three, the sprocket two and the sprocket three rotate synchronously, and the cylindrical gear one on the right rotates synchronously with the cylindrical gear two, so that the cylindrical gears one on the left and right sides rotate in the opposite direction, driving the semicircular gears on the left and right sides to rotate in the opposite direction, thereby driving the detection probe to continue to rotate 180°, and finally making the detection probe rotate one circle to obtain more detailed test data.

[0021] 6. In the present invention, the length of the connecting plate is adjusted by the connecting rod to change the horizontal displacement of the sprocket wheel 2, thereby compensating for the deformed toothed chain belt 1, ensuring that the toothed chain belt 1 is always in a taut state, and ensuring the smooth transmission between the sprocket wheel 1, the sprocket wheel 2, the sprocket wheel 3 and the toothed chain belt 1.
