[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] like Figure 1 As shown, a vehicle bridge test equipment includes a supporting bridge 1, and also includes a shelf structure and a pressing mechanism 7 that cooperate with the supporting bridge 1. The supporting bridge 1 includes an axle beam 2, and the shelf structure includes relatively arranged shelf frames 5. The shelf frames 5 on both sides are provided with limiting grooves 6 that cooperate with the axle beam 2.

[0022] Through the above structure, the support bridge 1 that needs to be tested can be shelved using the shelving structure. How to perform the test, the specific structure is as follows:

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the pressing mechanism 7 includes at least one hydraulic cylinder 9 which is evenly arranged relative to each other, the lower ends of the hydraulic cylinders 9 are fixedly connected with mounting frames 8, the bottoms of the mounting frames 8 are adhered with anti-skid pads, the hydraulic cylinders 9 are respectively located on both sides of the shelf 5, the upper ends of the hydraulic cylinders 9 are provided with a supporting frame 11, the four corners of the lower ends of the supporting frame 11 are fixedly connected with corner limiting plates 10 which cooperate with the hydraulic cylinder 9, which can prevent the supporting frame 11 from separating from the upper ends of the hydraulic cylinders 9 and can limit the supporting frame 11, at least one evenly arranged supporting plate 12 is fixedly connected in the supporting frame 11, the supporting plate 12 is fixedly connected with a connecting plate 13, the lower end of the connecting plate 13 is fixedly connected with a pressing plate 14 which cooperates with the axle beam 2, the lower end of the pressing plate 14 is provided with a protrusion which cooperates with the axle beam 2, so that the axle beam 2 can be subjected to concentrated force.

[0024] Through the above structure, a heavy object is placed on the object-bearing frame 11, and the hydraulic cylinder 9 is controlled to contract, so that the protrusion can be used to press down the axle beam 2, thereby testing the load-bearing performance of the axle beam 2.

[0025] Embodiment 2

[0026] like Figure 1 As shown, the shelf structure is provided with a shelf plate 3 matched with the shelf rack 5 , the shelf plate 3 is provided with a shelf groove 4 matched with the shelf rack 5 , and the shelf rack 5 is fixedly connected to the inner wall of the shelf groove 4 .

[0027] Through the above structure, the stability of the shelf 5 can be improved.

[0028] When the utility model is implemented, if it is necessary to test the bearing performance of the axle beam of the supporting bridge, the supporting bridge is first placed in the resting groove, and the axle beam is placed in the limit grooves on both sides. At this time, the protrusion of the lower pressure plate is located above the axle beam, and then the testing test can be started. Specifically, heavy objects are placed on the upper ends of the object-bearing frame and the object-bearing plate, and then the hydraulic cylinders are controlled to contract at the same time, and the object-bearing frame will drop until the lower pressure plate contacts the axle beam and generates pressure on the axle beam, and the deformation of the axle beam is observed;

[0029] When replacing weights of different weights, first control the hydraulic cylinder to extend and the supporting frame to rise, then replace the weights of different weights on the supporting plate, and repeat the above-mentioned pressing operation. The axle beam can be tested with different pressures. In this way, when testing the bearing performance of the axle beam supporting the bridge, there is no need to install it on a trailer for actual road driving test, which facilitates the detection test.

[0030] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
