For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0073] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0074] Example:

[0075] like Figure 1 As shown, an embodiment of the present application discloses a detection vehicle for dynamically and quickly spot-checking measuring equipment on a highway to assess whether its measurement data is accurate and whether it needs to be adjusted. Its structure includes: a tractor 1, a trailer 2, a carriage 3, a length adjustment mechanism 4, a width adjustment mechanism 5, a height adjustment mechanism 6, a side window mechanism 7 and a top window mechanism 8.

[0076] The tractor 1 is used to provide the forward power of the whole vehicle, that is, to pull the whole vehicle to move. It is a mature device in the prior art, so the specific structure is not described in detail.

[0077] The front bottom of the trailer 2 is connected to the tractor 1; it can be a semi-trailer or a full trailer, without limitation; specifically, the connection with the tractor 1 is achieved through a saddle, thereby achieving a rotational connection with the tractor 1, thereby meeting the turning requirements of the vehicle, which belongs to the prior art, so the specific structure is not described in detail.

[0078] The carriage 3 is installed on the top of the trailer 2, and has a top plate 31 and side plates 32 located on both sides of the top plate 31. The whole structure is a rectangular parallelepiped and has pillars around it.

[0079] The length adjustment mechanism 4 is installed at the front bottom of the tractor 1 and is used to adjust the length of the entire vehicle.

[0080] The width adjustment mechanism 5 is installed in the carriage 3 and is used to adjust the width of the entire vehicle.

[0081] The height adjustment mechanism 6 is installed in the vehicle compartment 3 and is used to adjust the height of the entire vehicle.

[0082] The side window mechanism 7 is mounted on the side panel 32 and corresponds to the width adjustment mechanism 5 , and can be opened or closed, so that the width adjustment mechanism 5 can be extended out of the vehicle compartment 3 to adjust the width of the entire vehicle.

[0083] The top window mechanism 8 is installed on the top plate 31 and corresponds to the height adjustment mechanism 6 , and can be opened or closed, so that the height adjustment mechanism 6 can be extended out of the vehicle compartment 3 to adjust the height of the entire vehicle.

[0084] In the above technical solution, by setting up a length adjustment mechanism 4, a width adjustment mechanism 5 and a height adjustment mechanism 6, the length, width and height of the whole vehicle can be adjusted, so that the measuring equipment on the highway can be dynamically and quickly inspected to assess whether the measurement data is accurate and whether it needs to be adjusted. Then, a side window mechanism 7 and a top window mechanism 8 are set, so that the width adjustment mechanism 5 and the height adjustment mechanism 6 can be extended out of the car 3 for easy storage and protection.

[0085] In some embodiments, Figure 1 and Figure 3 As shown, in order to improve the detection functionality, it also includes: an axle load adjustment mechanism 9, which can realize the change of the axle load; in addition, a load sensor is installed at the axle of the vehicle, so that the axle load data can be displayed on the display screen in the cab.

[0086] For example, if the axle load adjustment mechanism 9 adjusts the axle load of the vehicle axle to G; when the vehicle is inspected at a high-speed inspection station, the data is g; if the difference between g and G is within the allowable range, it means that the weight detection equipment of the inspection station is intact, otherwise the equipment of the inspection station needs to be calibrated.

[0087] Specifically, the axle load adjustment mechanism 9 includes:

[0088] The two support bases 91 are respectively installed on both sides of the vehicle compartment 3 in the length direction of the vehicle. The support bases 91 are in a right-angled triangle structure and are fixedly installed on the floor of the vehicle compartment 3 .

[0089] Multiple adjustment components 92 are spaced apart from each other in the width direction of the vehicle, preferably arranged symmetrically about the axis in the length direction of the vehicle, with uniform force, and there can be three, five or more adjustment components, without limitation.

[0090] For example, Figure 3 As shown, the adjustment component 92 includes:

[0091] The track 921 is installed between the two support seats 91 to support and guide the counterweight block 922 to slide left and right;

[0092] The counterweight block 922 is slidably connected to the track 921 and has a rectangular parallelepiped structure;

[0093] One end of the first oil cylinder 923 is connected to the counterweight 922 , and the other end is connected to a support seat 91 ; specifically, the cylinder body is hinged to the support seat 91 , and the cylinder rod is hinged to the counterweight 922 .

[0094] In the above technical solution, the counterweight 922 can be moved left and right on the track 921 by driving the first oil cylinder 923, so as to realize the change of the axle load. The operation method is simple, the adjustment effect is fast, and the use effect is good.

[0095] In some embodiments, Figure 4 As shown, a support frame 10 is vertically installed in the carriage 3 , and the support frame 10 is perpendicular to the axis in the length direction of the entire vehicle. The support frame 10 is preferably arranged at the rear side of the carriage 3 .

[0096] like Figure 2 As shown, the length adjustment mechanism 4 includes a first electric push rod 41, the cylinder body of the first electric push rod 41 is axially installed at the front end bottom of the tractor 1 and arranged horizontally, so that the cylinder rod can extend forward.

[0097] The detection method is: operate the first electric push rod 41 to extend, and the extension amount makes the total length of the vehicle (the distance from the front end of the first electric push rod 41 to the rear end of the vehicle) a preset value A, which is displayed on the display screen in the cab. When the vehicle is inspected at the highway inspection station, the inspection data is a. If the difference between a and A is within the allowable range, it means that the length detection equipment of the inspection station is intact, otherwise the inspection station equipment needs to be adjusted.

[0098] Through the above method, the length of the whole vehicle can be adjusted conveniently, quickly and efficiently, and the device has a simple structure, is easy to produce and assemble, and is convenient for practical application.

[0099] like Figure 4 As shown, the width adjustment mechanism 5 includes two second electric push rods 51, and the cylinder bodies of the two second electric push rods 51 are installed on the support frame 10 in a transverse manner and opposite to each other. The cylinder bodies are arranged horizontally so that the cylinder rods extend to both sides.

[0100] The detection method is: when the side window mechanisms 7 on both sides are opened, the second electric push rod 51 can be extended to the outside of the car 3. When the vehicle is inspected at the high-speed inspection station, the second electric push rod 51 is operated to extend, and the extension amount makes the total width of the vehicle (i.e., the distance between the left and right ends of the second electric push rod 51) a preset value W. The system can calculate the width of the entire vehicle and display it on the display screen in the cab. If the width data measured by the inspection station is w, and the difference between w and W is within the allowable range, it means that the width detection equipment of the inspection station is intact, otherwise the equipment of the inspection station needs to be adjusted.

[0101] Through the above method, the width of the vehicle can be adjusted conveniently, quickly and efficiently, and the device has a simple structure, is easy to produce and assemble, and is convenient for practical application.

[0102] like Figure 4 As shown, the height adjustment mechanism 6 includes a third electric push rod 61, which is vertically mounted on the support frame 10, and the cylinder body is vertically arranged so that the cylinder rod can extend upward.

[0103] The detection method is: when the top window mechanism 8 is opened, the third electric push rod 61 can be extended to the outside of the car 3. When the vehicle is inspected at the high-speed inspection station, the third electric push rod 61 is operated to extend, and the extension amount makes the total height of the vehicle (the distance from the top of the third electric push rod 61 to the ground) a preset value H. The value is displayed on the cab display screen. If the height data measured by the inspection station is h, and the difference between h and H is within the allowable range, it means that the height detection equipment of the inspection station is intact, otherwise the equipment of the inspection station needs to be adjusted.

[0104] Through the above method, the height of the whole vehicle can be adjusted conveniently, quickly and efficiently, and the device has a simple structure, is easy to produce and assemble, and is convenient for practical application.

[0105] In some embodiments, Figure 4 and Figure 5 As shown, the side window mechanism 7 is designed so that a side window 321 is provided on the side plate 32, and the side window 321 is in a rectangular structure.

[0106] Specifically, the side window mechanism 7 includes:

[0107] The side window plate 71 is a concave structure, and one side is rotatably connected to the top of the side window 321; the shape and size match the side window 321, and the connection method is preferably a hinge, and it can also be other parts without limitation;

[0108] The limiting plate 72 is an L-shaped structure and is installed at the bottom of the side window 321;

[0109] The first flip assembly 73 has one end connected to the side window panel 71 and the other end connected to the side panel 32 , and is used to drive the side window panel 71 to flip.

[0110] The operation method is: start the first flip assembly 73, which pushes the side window panel 71 to flip until it rotates from a vertical state to a horizontal state, so that the side window 321 is no longer closed. At this time, the second electric push rod 51 can extend from the side window 321, and when the side window panel 71 is closed, it can fit together with the limit plate 72, thereby being blocked by the limit.

[0111] Through the above method, the opening and closing of the side window 321 can be completed quickly, and the structure is simple, the regularity is high, the sealing is good, and it is easy to produce.

[0112] For example, Figure 5 As shown, the first flip assembly 73 includes:

[0119] Specifically, the top window mechanism 8 includes:

[0120] The top window plate 81 is a concave structure, and one side is rotatably connected to the top window 311. The shape and size match the top window 311. The connection method is preferably a hinge, but it can also be other parts without limitation.

[0121] The return pipe 82 has a rectangular cross section and is installed in the top window 311;

[0122] Two second rubber strips 83 are installed on both sides of the top of the circular tube 82;

[0123] The second flip assembly 84 has one end connected to the top window plate 81 and the other end connected to the top plate 31 , and is used to drive the top window plate 81 to flip.

[0124] The operation method is: start the second flip assembly 84, which pushes the top window plate 81 to flip until it rotates from a horizontal state to a vertical state, so that the top window 311 is no longer closed. At this time, the third electric push rod 61 can extend from the top window 311, and when the top window plate 81 is closed, it can cover the return tube 82, thereby being blocked by the limit.

[0125] Through the above method, the top window 311 can be opened and closed quickly, and its structure is simple, regularity is high, sealing is good, and it is easy to produce.

[0126] For example, Figure 6 As shown, the second flip assembly 84 includes:

[0127] The second support 841 is installed on the top plate 31 and has a right-angle structure with high structural strength;

[0128] The second bracket 842 is installed on the top window plate 81 and has an L-shaped structure;

[0129] One end of the second cylinder 843 is hinged to the second support 841 , and the other end is hinged to the second bracket 842 .

[0130] The second flip assembly 84 arranged as above has the advantages of high connection stability, reasonable layout position, stable driving, etc., and is convenient for actual assembly and use.

[0131] In some embodiments, Figure 7 As shown, in order to facilitate the inspection of the equipment inside the carriage 3, the side plate 32 is L-shaped and hinged to the top plate 31;

[0132] In addition, it also includes: a side wing opening and closing mechanism 11, which is installed between the side panel 32 and the pillar of the carriage 3, and is used to drive the side panel 32 to flip; preferably, there are four side wing opening and closing mechanisms 11 and they are arranged around the carriage 3, and their supporting stability is high.

[0133] Exemplarily, the wing opening and closing mechanism 11 includes:

[0135] The fourth support 112 is mounted on the column of the carriage 3;
