[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0031] like Figures 1 to 9 As shown, a correction locking device for detachable vehicles includes a detachable locomotive frame 1 and a carriage 2 disposed above the detachable locomotive frame 1. It also includes correction frames 3 fixedly connected to the four corners of the interior of the detachable locomotive frame 1. Connecting blocks 4 are fixedly connected to the four corners of the bottom of the carriage 2. Locking mechanisms are provided on the front and rear sides of the correction frames 3.

[0032] like Figures 7 to 9 As shown, the position of the correction frame 3 corresponds one-to-one with the position of the docking block 4. The inner width of the correction frame 3 is greater than the width of the docking block 4. By setting the correction frame 3 and docking block 4 with corresponding positions on the detachable locomotive frame 1 and the car body 2 respectively, when the car body 2 is lowered and docked with the detachable locomotive frame 1 to complete the assembly, the one-to-one corresponding correction frame 3 and docking block 4 can interact to position and correct the left and right positions of the car body 2, so that the frame and the car body can complete the efficient and accurate assembly, and avoid the situation where the assembly of the two has deviations that affect the stability.

[0033] like Figures 1 to 3 As shown, the top of the correction frame 3 is V-shaped, and the top surface of the correction frame 3 is open on the side near the mounting part. The cross-sectional shape of the docking block 4 is trapezoidal, and the bottom slope of the docking block 4 is parallel to the top slope of the correction frame 3. By setting the top of the correction frame 3 to a V-shape, when the docking block 4 on the carriage 2 is biased towards the inside of the correction frame 3, the slope of the docking block 4 slides relative to the correction frame 3 to complete the correction, allowing the docking block 4 to enter the top opening of the correction frame 3 to complete the assembly. When the docking block 4 on the carriage 2 is biased towards the outside of the correction frame 3, the slope of the closed part at the top of the correction frame 3 interacts with the docking block 4, causing the docking block 4 and the carriage to complete the left and right movement correction, and then the docking block 4 enters the top opening of the correction frame 3 to complete the assembly. This device can efficiently realize the correction work when assembling the carriage and the truck bed, and the structure is simple and requires no additional operation. Example 2

[0034] like Figures 1 to 6As shown, a first roller 5 is rotatably connected to the top of the correction frame 3 near the mounting end. The length of the first roller 5 is adapted to the inner width of the correction frame 3. A second roller 6 is rotatably connected to the bottom of the docking block 4. By setting the first roller 5 on the correction frame 3, when the docking block 4 shifts inward, the bottom inclined surface of the docking block 4 contacts the first roller 5, and the left and right movement correction is completed by the sliding of the first roller 5. When the docking block 4 shifts outward, the second roller 6 on the docking block 4 interacts with the top inclined surface of the correction frame 3, thereby completing the left and right movement correction. The first roller 5 and the second roller 6 convert the sliding friction force in the correction process into rolling friction force, reducing the friction force in the correction process, thereby making the correction process smoother and avoiding wear caused by the correction frame 3 and the docking block 4 during the sliding correction process. Example 3

[0035] like Figures 1 to 6 As shown, the locking mechanism includes pressure cylinders 7 fixedly connected to both sides of the correction frame 3, and a locking block 8 fixedly connected to the output end of the pressure cylinders 7.

[0036] The bottom of the docking block 4 is provided with a locking hole 9. When the docking block 4 and the correction frame 3 are docked, the position of the locking hole 9 corresponds to the position of the locking block 8. By setting the locking hole on the docking block 4 and setting the locking block 8 driven by the pressure cylinder 7 on the correction frame 3, after the correction assembly of the detachable locomotive frame 1 and the carriage 2 is completed, the locking block 8 is exactly aligned with the locking hole 9. Then, the pressure cylinder 7 is activated to extend its output end, and the locking block 8 is extended into the locking hole 9 to complete the locking and engagement, so that the correction frame 3 and the docking block 4 are locked and assembled, and the detachable locomotive frame 1 and the carriage 2 are locked and assembled, improving the stability of the carriage 2 assembly. Moreover, the locking structure is stable and does not require manual operation.

[0037] like Figures 5 to 6 As shown, the end of the locking block 8 is semi-elliptical, and the diameter of the locking block 8 is adapted to the inner diameter of the locking hole 9. By setting the locking block 8 to a semi-elliptical shape, the outer surface of the locking block 8 is an arc-shaped bevel. When there is a slight deviation between the locking hole 9 and the locking block 8, the arc-shaped bevel on the outer side of the locking block 8 can slightly adjust the position of the docking block 4 with the locking hole 9, making the process of the locking block 8 being inserted into the locking hole 9 to complete the locking process smoother and more accurate.

[0038] like Figures 5 to 6 As shown, when the pressure cylinder 7 is fully extended, the ends of the two locking blocks 8 are in contact with each other. The extension stroke of the pressure cylinder 7 is equal to half the width of the inner wall of the correction frame 3. By limiting the extension stroke and extension position of the pressure cylinder 7, it can fully lock when it is extended and be located outside the correction frame 3 when it is retracted, so as to avoid affecting the interaction between the docking block 4 and the correction frame 3.

[0039] The working principle of the utility model is as follows:

[0040] S1, when the butt joint block 4 on the carriage 2 is deviated to the inner side of the rectification frame 3, the inclined surface of the butt joint block 4 and the rectification frame 3 slide relative to each other to complete rectification, so that the butt joint block 4 enters the top opening of the rectification frame 3 to complete assembly;

[0041] S2, when the butt joint block 4 on the carriage 2 is deviated to the outer side of the rectification frame 3, the inclined surface of the closed part at the top of the rectification frame 3 and the butt joint block 4 interact with each other, so that the butt joint block 4 and the carriage complete left-right movement rectification, and then the butt joint block 4 enters the opening at the top of the rectification frame 3 to complete assembly;

[0042] S3, after the rectification assembly of the detachable locomotive frame 1 and the carriage 2 is completed, the locking block 8 is aligned with the locking hole 9, then the pressure cylinder 7 is started to make its output end elongate, then the locking block 8 is inserted into the locking hole 9 to complete cooperation locking, so that the rectification frame 3 and the butt joint block 4 complete locking assembly, and further make the detachable locomotive frame 1 and the carriage 2 complete locking assembly.

[0043] The above is only used to explain the technical scheme of the utility model, not to limit it, and other modifications or equivalent replacements of the technical scheme of the utility model made by the ordinary skilled in the art should be covered in the scope of the claims of the utility model, as long as they do not deviate from the spirit and scope of the technical scheme of the utility model.
