[0002] Special vehicles generally refer to vehicles whose external dimensions, weight, etc., exceed the design limits of vehicles, or vehicles for special purposes, or motor vehicles that have been specially made or modified and equipped with fixed devices and equipment, whose primary function is not to carry passengers or goods. These vehicles are usually used for special work or specific purposes and may display special vehicle license plates and be equipped with sirens and warning lights.

[0003] Special-purpose vehicles are widely used in various fields, including but not limited to: public safety, infrastructure construction, urban sanitation, cold chain logistics, and public utilities. In summary, special-purpose vehicles play an irreplaceable role in modern society, not only improving work efficiency but also ensuring public safety and social order.

[0004] Currently, the market for special-purpose vehicles is expanding, and the demand for new model development is also increasing. Before being launched on the market, new models must undergo reliability testing, with verifying their reliability under various operating conditions when fully loaded being an indispensable test. However, some monocoque chassis, especially turret-type superstructure vehicles, have structures different from traditional truck chassis and lack a frame structure. Conventional truck chassis have a frame, which can be used to add subframes and cargo boxes for counterweights. However, adding loads to special-purpose vehicles is extremely difficult, and the loads used in testing are generally counterweights, which are quite heavy. If these counterweights loosen, they can easily cause serious accidents, posing safety hazards and affecting the testing process. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing special vehicle chassis where it is difficult to add counterweights and the counterweights are prone to loosening, which affects the test verification. This invention provides a special vehicle chassis test loading device with a reasonable design, simple structure, convenient addition of counterweights, and high stability of the counterweights. It can not only effectively improve work efficiency, but also reduce safety hazards, which is conducive to test verification and suitable for promotion.

[0006] This utility model is achieved through the following technical solution: a special vehicle chassis test loading device includes a base assembly for connecting to a vehicle chassis, and a frame mechanism for loading counterweights is provided on the base assembly; the frame mechanism includes a supporting frame, which is disposed on the base assembly, and end stops are respectively provided at both ends of the supporting frame, and side stops are respectively provided on both sides of the supporting frame between the two end stops, so that the supporting frame, end stops and side stops can form a frame mechanism with a top opening; a number of counterweights can be placed inside the frame mechanism, and a number of pressure plates pressing on the top side of the counterweights are provided at the top opening of the frame mechanism, and the two ends of the pressure plates are respectively connected to the two sides of the supporting frame through fastening components, so that the pressure plates can press the counterweights in the frame mechanism.

[0007] When testing and verification are required, staff can install the loading device on a vehicle chassis or turret using bolt assemblies and base assemblies. Then, an appropriate amount of counterweights is selected according to the actual test requirements and placed inside the frame mechanism. After the counterweights are placed, a pressure plate is pressed onto the top side of the counterweights and secured firmly using fastening components. The entire installation process is very convenient, greatly reducing the difficulty of loading the counterweights. Furthermore, the cooperation of the pressure plate, fastening components, and frame mechanism ensures the stability and reliability of the counterweights, avoiding potential accidents caused by loose counterweights and effectively improving the safety of the testing and verification process, reducing safety hazards. Moreover, staff can easily remove the pressure plate using the fastening components, allowing for the replacement of different specifications and quantities of counterweights according to test requirements. This enables convenient adjustment of the loading load and the position of the load center of gravity, thereby improving the adaptability of the loading device.
