Description

Technical Field

[0001] This utility model relates to the field of bridge load-bearing capacity testing technology, and in particular to a bridge load-bearing capacity testing device. Background Technology

[0002] Bridge load-bearing capacity testing refers to a series of tests and evaluations conducted on a bridge structure to determine the maximum load it can safely bear under its current condition. In the field of bridge engineering, concrete, as the main building material, has a strength value that is an important indicator for evaluating the safety performance and load-bearing capacity of a bridge structure.

[0003] Current bridge load-bearing capacity testing typically involves manually testing the rebound value of the test surface using a concrete rebound hammer, then spraying phenolphthalein reagent onto the test area, and finally inserting a carbonation depth tester to measure the carbonation value of the concrete. The bridge strength is then assessed by combining the carbonation value with the rebound value. However, the entire testing process relies on manual operation, which is cumbersome, time-consuming, and inefficient, thus affecting work efficiency and causing considerable inconvenience.

[0004] Therefore, it is necessary to design a bridge load-bearing capacity testing device that can automatically detect concrete strength values, reduce manual operation, save manpower and time, and improve work efficiency. Utility Model Content

[0006] The technical implementation scheme of this utility model is as follows:

[0007] A bridge load-bearing capacity testing device includes a base wheel, a connecting frame, a first motor, a main frame, a moving frame, a controller, and a testing component.

It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0023] A bridge load-bearing capacity testing device, such as Figure 1 , Figure 4 and Figure 5 As shown, it includes a base wheel 1, a connecting frame 2, a first motor 3, a main frame 6, a moving frame 7, a controller 8, and a detection component. The moving frame 7 has two parts, left and right. The right moving frame 7 has a push handle for easy gripping and pushing. The connecting frame 2 is rotatably connected to the base wheel 1 on both the front and rear sides. The left moving frame 7 is connected to the upper part of the connecting frame 2. The first motor 3 is connected to the inner left side of the connecting frame 2. The output shaft of the first motor 3 is connected to the main frame 6. The main frame 6 is rotatably connected to the right connecting frame 2. The controller 8 is connected to the upper side of the right moving frame 7. The main frame 6 is equipped with a detection component.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the detection assembly includes a reagent chamber 10, a reaction reagent nozzle 12, an ultrasonic detector 13, a carbonation depth detector 14, a concrete rebound hammer 15, a first electric actuator 16, a second electric actuator 17, a third electric actuator 18, a third motor 20, a lead screw 21, and a spring 22. Two third motors 20 are connected to the inner front part of the main frame 6. Each third motor 20 has a lead screw 21 connected to its output shaft. The lead screws 21 are rotatably connected to the main frame 6. The left lead screw 21 has a threaded moving block that is slidably connected to the main frame 6. The right lead screw 21 also has a threaded moving block. The movable plate is slidably connected to the main frame 6. A reagent chamber 10 is connected to the upper side of the movable plate. A reaction reagent nozzle 12 is connected to the reagent chamber 10 via a hose. A first electric actuator 16 is connected to the lower side of the movable plate. An ultrasonic detector 13 is connected to the telescopic end of the first electric actuator 16. A third electric actuator 18 is connected to the lower side of the movable plate. A carbonation depth detector 14 is connected to the telescopic end of the third electric actuator 18 via a spring 22. The carbonation depth detector 14 is connected to the reaction reagent nozzle 12. A second electric actuator 17 is connected to the rear of the movable plate. A concrete rebound hammer 15 is connected to the telescopic end of the second electric actuator 17.

[0025] like Figures 1-4 As shown, it also includes a second motor 4, a cleaning brush head 5, a pigment tank 9, a marking nozzle 11, and a camera 19. The second motor 4 is connected to the lower left side of the connecting frame 2. The cleaning brush head 5 is connected to the output shaft of the second motor 4. The pigment tank 9 is connected to the upper side of the moving block. The marking nozzle 11 is connected to the pigment tank 9 through a hose. The ultrasonic detector 13 is connected to the marking nozzle 11. The camera 19 is connected to the right side of the moving plate.

[0026] When using this device, first push the connecting frame 2 onto the bridge, then start the second motor 4 through the controller 8 to drive the cleaning brush head 5 to rotate. The cleaning brush head 5 cleans the area to be tested. After cleaning, start the first electric push rod 16 to drive the ultrasonic detector 13 to move downwards, so that the ultrasonic detector 13 is close to the testing area. Then start the third motor 20 on the left to drive the lead screw 21 to rotate, so that the moving block moves back and forth under the action of the thread. The ultrasonic detector 13 detects cracks and voids inside the concrete and around the steel bars.

[0027] When the ultrasonic detector 13 detects cracks and voids in certain areas of the reinforcing steel, pressing the pigment chamber 9 causes paint to be sprayed through the marking nozzle 11 for marking. This allows for marking when cracks and voids are detected in the reinforcing steel, facilitating subsequent detailed inspection and repair. After the reinforcing steel inspection is completed, the third motor 20 on the right is activated, driving the lead screw 21 to rotate, causing the moving plate to move under the action of the thread. Subsequently, the second electric actuator 17 is activated, driving the concrete rebound hammer 15 downwards, so that the concrete rebound hammer 15 contacts the bridge inspection area, and then... The second electric actuator 17 controls the concrete rebound hammer 15 to move upward, and the rebound value is detected by the concrete rebound hammer 15. Then, the third electric actuator 18 is activated to drive the carbonation depth detector 14 to move downward. The detection area is observed through the camera 19. Then, the reagent chamber 10 is pressed, so that the phenolphthalein reagent is sprayed out through the reaction reagent nozzle 12 to the detection area. When the carbonation depth detector 14 moves downward, the spring 22 will be squeezed and contracted. The spring 22 provides buffering. The carbonation depth detector 14 moves downward and inserts the detection head into the bridge detection area to detect the concrete carbonation value.

[0028] The strength of the bridge is evaluated by measuring the carbonation value and rebound value, thus enabling fully automated testing of concrete strength. This reduces manual operation, saves manpower and time, and improves work efficiency. After the test is completed, the carbonation depth detector 14 is moved upward by the third electric actuator 18, and the spring 22 returns to its original position, allowing the carbonation depth detector 14 to be removed from the testing area. When it is necessary to test both sides of the bridge, the first motor 3 on the connecting frame 2 can be started to rotate the main frame 6, so that the ultrasonic detector 13, carbonation depth detector 14 and concrete rebound hammer 15 face the testing surface. This allows the ultrasonic detector 13, carbonation depth detector 14 and concrete rebound hammer 15 to be rotated, facilitating the testing of both sides of the bridge.
