[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a heavy engineering machinery vehicle disassembly and assembly device, including a forklift body 1 and a mounting frame 2. Two brackets 3 are fixed to the front side of the mounting frame 2. The two brackets 3 are L-shaped. A first limiting block 4 is fixed to the lower end of the brackets 3. Guide rods 5 are fixed to the front side of both brackets 3. A mounting plate 6 is fixed between the two guide rods 5. A movable frame 7 is slidably connected between the two guide rods 5. The movable frame 7 is a door-shaped structure. A screw 8 is threaded inside the movable frame 7. One end of the screw 8 is rotatably connected to the outside of the mounting frame 2. The other end of the screw 8 is rotatably connected to the outside of the mounting plate 6. A second limiting block 9 is fixed to the lower end of the movable frame 7. The second limiting block 9 and the first limiting block 4 are both triangular structures. A motor 10 is fixed to the rear side of the mounting frame 2. The output end of the motor 10 passes through the interior of the mounting frame 2 and is coaxially fixedly connected to one end of the screw 8.

[0023] The mounting frame 2 is moved above the support rollers and guide rollers by the forklift body 1, so that the support rollers and guide rollers are on the brackets 3 and 7. Then, the brackets 3 and 7 are lowered, and the motor 10 is started to drive the lead screw 8 to rotate. The lead screw 8 drives the 7 to move along the guide rod 5 toward the bracket 3. During this process, the first limit block 4 and the second limit block 9 on the brackets 3 and 7 lift the support rollers and guide rollers from below. Then, the support rollers and guide rollers are moved to the designated position by the forklift body 1. Then, by reversing the motor 10, the lead screw 8 drives the 7 to move away from the bracket 3 along the guide rod 5, thereby lowering the support rollers and guide rollers. This solves the problem of having to manually place the support rollers and guide rollers on the forklift and then manually remove them after moving them to the designated position, which is time-consuming and labor-intensive.

[0024] Furthermore, two sliding grooves 11 are provided on the front side of the movable frame 7. A third limiting block 12 is slidably connected to the inner side of the sliding groove 11. The third limiting block 12 has a triangular structure. A connecting plate 13 is fixed between the two third limiting blocks 12. A sleeve 14 is fixed to the middle of the rear side of the connecting plate 13. A vertical plate 15 is slidably connected to the inner side of the sleeve 14. The upper end of the vertical plate 15 is fixedly connected to the outer side of the movable frame 7. Multiple slots 16 are provided on the front side of the vertical plate 15. A handle 17 is fixed to the front side of the connecting plate 13. A plug rod 18 is slidably connected to the outer side of the handle 17. One end of the plug rod 18 passes through the interior of the connecting plate 13 and is inserted into the inner side of the slot 16. A spring 19 is fixed between the plug rod 18 and the handle 17.

[0025] By pushing the connecting plate 13 up and down along the vertical plate 15 with the handle 17, the connecting plate 13 drives the third limiting block 12 up and down along the slide groove 11 on the moving frame 7, thereby adjusting the distance between the third limiting block 12 and the second limiting block 9, so that the third limiting block 12 can fit against the support wheel and the guide wheel. During the movement, the function of stabilizing the support wheel and the guide wheel is activated. The insertion rod 18 is inserted into the slot 16 on the vertical plate 15 under the action of the spring 19, thereby fixing the position of the connecting plate 13 and the third limiting block 12, which is convenient and quick to use.

[0026] The specific usage and function of this embodiment: The present invention moves the mounting frame 2 above the support roller and guide roller by the forklift body 1, so that the support roller and guide roller are on the support of the bracket 3 and the movable frame 7. Then, the bracket 3 and the movable frame 7 are lowered, and the motor 10 is started to drive the lead screw 8 to rotate. The lead screw 8 drives the movable frame 7 to move along the guide rod 5 toward the bracket 3. During this process, the first limiting block 4 and the second limiting block 9 on the bracket 3 and the movable frame 7 lift the support roller and guide roller from below. Then, the support roller and guide roller are moved to the designated position by the forklift body 1. Then, by reversing the motor 10, the lead screw 8 drives the movable frame 7 away from the bracket 3 along the guide rod 5, thereby lowering the support roller and guide roller.

[0027] By pushing the connecting plate 13 up and down along the vertical plate 15 with the handle 17, the connecting plate 13 drives the third limiting block 12 up and down along the slide groove 11 on the moving frame 7, thereby adjusting the distance between the third limiting block 12 and the second limiting block 9, so that the third limiting block 12 can fit against the support wheel and the guide wheel. During the movement, the function of stabilizing the support wheel and the guide wheel is activated. The insertion rod 18 is inserted into the slot 16 on the vertical plate 15 under the action of the spring 19, thereby fixing the position of the connecting plate 13 and the third limiting block 12.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
