Technical Field
[0001] This utility model belongs to the field of bridge model testing technology, specifically relating to a multifunctional bridge model performance testing device. Background Technology
[0002] Bridge model competitions are a key platform for evaluating the level of bridge design and construction. The load-bearing capacity and impact resistance of the models are core evaluation indicators, which need to be objectively assessed through multi-dimensional testing to provide a scientific basis for fair judging of the competition.
[0003] Current bridge model inspection has significant shortcomings: traditional manual inspection relies on simple tools and subjective judgment, making it difficult to accurately quantify key data such as deformation and impact resistance; existing inspection devices have limited functions, mostly only capable of static load-bearing tests, and cannot simulate complex scenarios such as vehicle traffic and unexpected impacts in competitions, and parameter adjustments are inconvenient, making it difficult to meet the competition's demand for multi-dimensional and rapid and accurate inspection of models, resulting in a lack of comprehensive data support for evaluation.
[0004] As bridge model competitions become increasingly professional, the demand for comprehensive and accurate testing is becoming more urgent. There is a pressing need for a testing device that can provide multiple testing methods tailored to competition scenarios, simulate actual working conditions, flexibly adjust parameters, solve the bottlenecks of traditional testing, and provide reliable data support for competition evaluation and model performance optimization.

[0017] like Figure 1-2As shown, the multifunctional bridge model performance testing device includes a support frame 1, on which a lower mounting frame 2 and an upper mounting frame 3 are mounted. A left support plate 4 is mounted at one end of the lower mounting frame 2, and a right support plate 5 is mounted at the other end. Lifting plates 6 are respectively located on the outer sides of the left and right support plates 4 and 5. The lifting plates 6 are controlled by a lifting control mechanism. A load-bearing trolley 7 is placed on one lifting plate 6, and a winding wheel 8 is mounted on the other lifting plate 6. The winding wheel 8 is driven to rotate by a motor 9. The load-bearing trolley 7 is connected by a pull rope. A receiving reel 8 is mounted on the upper mounting frame 3. A lower pressure plate 10 is installed in the middle of the upper mounting frame 3. The lower pressure plate 10 is driven to move up and down by a lower pressure electric push rod 11. A pressure sensor and an electromagnet are installed on the lower pressure plate 10. An impact hammer 12 is magnetically attracted to the lower pressure plate 10 through the electromagnet. An inclined tube 13 is installed at one end of the upper mounting frame 3. The lower end of the inclined tube 13 points to the middle of the lower mounting frame 2. Several infrared distance detectors 14 are installed below the middle of the lower mounting frame 2. A display is installed on the bracket 1 to display the values of the infrared distance detectors 14. The two ends of the bridge model are placed on the left support plate 4 and the right support plate 5 respectively. The height of the lifting plate 6 is adjusted so that the lifting plate 6 is level with the bridge model. A certain load is attached to the load trolley 7. The motor 9 drives the take-up reel 8 to rotate, pulling the load trolley 7 across the bridge surface of the bridge model. The deformation of the bridge model is sensed by the infrared distance detectors 14. The downward-pressing electric push rod 11 drives the lower pressure plate 10 to descend, applying pressure to the middle of the bridge model. The infrared distance detector 14 senses the deformation of the bridge model. The lower pressure plate 10 rises to a certain height and magnetically attracts the impact hammer 12 via an electromagnet. Then, the electromagnet is de-energized, and the impact hammer 12 falls freely, impacting the bridge model. The infrared distance detector 14 senses the deformation of the bridge model. A test ball of a specific weight is dropped into the inclined tube 13 from the top. The test ball falls along the inclined tube 13, impacting the bridge model at a certain angle. The infrared distance detector 14 senses the deformation of the bridge model. The infrared distance detector 14 can also be replaced by a light curtain sensor. The transmitter and receiver of the light curtain sensor are installed on both sides of the bridge model, with adjustable height, or multiple sensors can be arranged from top to bottom. Once the bridge model deforms, the light curtain between the transmitter and receiver is broken, generating a deformation signal, thus quickly and easily determining whether the bridge model is qualified, forming a rapid detection method.
[0018] Furthermore, the lifting control mechanism is a shear-type lifting mechanism 15, which is driven to lift via a screw 16, on which a handwheel is fixedly connected. By rotating the screw 16, the height of the lifting plate 6 is adjusted so that it matches the height of the bridge model, allowing the trolley 7 to smoothly pass over the bridge model.
[0019] Furthermore, the impact hammer 12 is connected to the upper mounting frame 3 via a pull rope. After the impact hammer 12 free-falls and impacts the bridge model, the pull rope holds the impact hammer 12, facilitating its quick retraction.
[0020] Furthermore, the lower mounting frame 2 is provided with several lower sliding rails 17, and several sliders 18 are fixedly connected to the left support plate 4 and the right support plate 5 respectively. The sliders 18 slide in engagement with the lower sliding rails 17, and the sliders 18 are fixed to the lower sliding rails 17 by locking bolts. The positions of the left support plate 4 and the right support plate 5 are adjustable to accommodate bridge models of different lengths.
[0021] Furthermore, the upper mounting frame 3 is equipped with several upper slide rails 19. Rotary shafts 20 are fixedly connected to both sides of the upper end of the inclined tube 13. Each rotating shaft 20 is rotatably connected to a movable plate 21, which is slidably mounted on the upper slide rails 19. The lower end of the inclined tube 13 is connected to a hanging rod 23 via a suspension rope 22. Both ends of the hanging rod 23 are slidably connected to the upper slide rails 19. By adjusting the length and position of the suspension rope 22, the angle and lower end position of the inclined tube 13 can be adjusted according to testing requirements.
[0022] Furthermore, positioning clamps 24 are respectively provided on both sides of the left support plate 4 and both sides of the right support plate 5. Adjusting screws 16 are fixedly connected to the positioning clamps 24, and the adjusting screws 16 are rotatably connected to a fixing plate 25. The fixing plate 25 is fixedly connected to either the left support plate 4 or the right support plate 5. After placing both ends of the bridge model on the left support plate 4 and the right support plate 5 respectively, rotating the adjusting screws 16 causes the positioning clamps 24 to clamp the bridge model, thus positioning the bridge model and preventing it from slipping during testing.
[0023] Furthermore, a storage battery is installed on the bracket 1, and the motor 9, electromagnet, infrared distance detector 14, display, pressure sensor, and downward electric push rod are all connected to the storage battery for power supply. The storage battery provides power, and the entire detection device is portable, allowing it to be moved to various locations within schools, such as playgrounds, auditoriums, and sports stadiums. It can also be connected to mains power via a power cord.
[0024] It is worth mentioning that the technical features involved in this utility model patent application, such as the storage battery, motor 9, electromagnet, infrared distance detector 14, display, downward electric push rod, and shear-type lifting mechanism 15, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.
[0025] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
