Description

Technical Field

[0001] The utility model relates to the technical field of stress real test devices, in particular to a bridge stress real test device with a beam-arch structure. Background Art

[0002] A bridge stress test device with a beam-arch structure can be used to simulate the stress conditions of an actual bridge to evaluate the strength and stability of its structure. Through this experimental device, the stress distribution and structural response of the bridge under different load conditions can be simulated to evaluate its strength and stability, and provide a reference for actual bridge design and maintenance. Please note that during the experimental design and operation, relevant safety regulations and operating procedures should be followed to ensure the safety of the experiment.

[0003] At present, the existing stress test device for bridges with beam-arch structures has a fixed size and an integrated design, which easily leads to a poor measurement experimental effect when the device is used to perform stress tests on bridges with beam-arch structures of the same height. When facing different heights, due to the different telescopic lengths of the hydraulic rods, the forces released when pressing down and the interferences received are also different, which easily leads to deviations in measurement, affecting the measurement accuracy and the efficiency of the device.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the existing stress testing device is inconvenient to perform stress experiments on different bridges when in use. The overall idea is as follows: A stress testing device for a bridge with a beam-arch structure comprises a fixed base 1, a connecting side plate 13 is installed at the side end of the fixed base 1, and a stress testing device 11 is installed at the upper end of the fixed base 1; wherein, a support plate 2 is slidably installed at the side end of the connecting side plate 13, and a pushing motor 21 is installed inside the support plate 2; wherein, a pushing rod 22 is slidably installed inside the pushing motor 21, and a pressure column 23 is installed at the lower end of the pushing rod 22, and the stress testing device 11 part cooperates with the sensor pressure plate 12 part, so that the device can measure the stress of the bridge model when in use.

[0023] In view of the problems existing in the prior art, the utility model provides a bridge stress test device with a beam-arch structure, wherein a sensor pressure plate 12 is slidably installed on the upper end of the stress testing device 11; two bolts 14 are threadedly installed on the side end of the connecting side plate 13, and two limiting holes 15 are provided on the upper end of the connecting side plate 13; the connecting side plate 13 is installed on the side end of the fixed base 1 by matching the bolts 14 with the side end openings of the fixed base 1, and the threaded rotating rod 16 installed inside the connecting side plate 13 can achieve the goal of quickly installing the threaded rotating rod 16 when the device is in use.

[0024] Two threaded rotating rods 16 are rotatably installed inside the connecting side plate 13; each threaded rotating rod 16 is installed inside the connecting side plate 13 through a limiting hole 15, and the upper end of each threaded rotating rod 16 is sleeved with the same transmission belt 17; a rotating motor 18 is rotatably installed on the upper end of one of the threaded rotating rods 16, and the rotating motor 18 cooperates with the transmission belt 17 to drive the threaded rotating rod 16 to rotate, thereby driving the support plate 2 part to adjust the height, and cooperate with the stress testing device 11 part to achieve stress measurement of the bridge model.

[0025] The support plate 2 is slidably installed at the side end of the connecting side plate 13 by cooperating with the threaded rotating rod 16; the side end of the pushing rod 22 is rotatably installed with a buckle 24, and the pressure column 23 is installed under the pushing rod 22 through the side end opening of the pushing rod 22 and cooperating with the buckle 24. The pressure column 23 is quickly fixed by the buckle 24, so that the pressure column 23 can be quickly replaced when the device is in use, thereby performing stress testing on different points of the bridge model.

[0026] Working principle:

[0027] The first step is that when using, the user places the device on a horizontal surface, picks up the fixed base 1, installs the stress test device 11 on the fixed base 1, and then installs the sensor pressure plate 12 on the stress test device 11. Then the user picks up the connecting side plate 13, and installs two threaded rotating rods 16 along the two limiting holes 15 opened on the connecting side plate 13. Then the user picks up the transmission belt 17, connects the two threaded rotating rods 16, and then installs the rotating motor 18 on one of the threaded rotating rods 16. Then the user picks up the support Plate 2, install the pushing motor 21 inside the support plate 2, then pick up the pushing rod 22, install the pressure column 23 under the pushing rod 22, and then install the buckle 24 from the side end of the pushing rod 22 to fix the pressure column 23 and the pushing rod 22 part. Then the user installs the assembled pushing rod 22 part into the pushing motor 21, and then the user connects the assembled support plate 2 part along the side end opening with the threaded rotating rod 16 part, and then connects the assembled connecting side plate 13 part with the fixed base 1 part with the bolts 14.

[0028] In the second step, when the user needs to use the device, the user places the scaled bridge model on the fixed base 1 for fixation, and then the user starts the rotating motor 18, and the rotating motor 18 cooperates with the transmission belt 17 to drive the two threaded rotating rods 16 to rotate, thereby driving the support plate 2 to slide down until the bottom of the support plate 2 is close to the top of the bridge model, and then the user starts the stress testing device 11, and the stress testing device 11 lifts the sensor pressure plate 12 until it fits with the bottom of the bridge model, and then the user starts the pushing motor 21, and the pushing motor 21 pushes the pushing rod 22 downward, thereby pushing the pressure column 23 from the top of the bridge model, and cooperates with the stress testing device 11 at the bottom to measure the stress of the bridge, and by starting the rotating motor 18 to adjust the height position of the support plate 2, the device can perform stress measurement experiments on different bridge models to improve the experimental efficiency.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
