[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1 - Figure 4 As shown, the utility model provides a main beam and support beam positioning device for a trough semi-trailer, comprising a workbench 1, a rotating mechanism 2 is provided on the top of the workbench 1, a part main beam 3 is provided on the top of the rotating mechanism 2, a part support beam 4 is provided on the top of the part main beam 3, a pushing mechanism 5 is provided on the top of the workbench 1, a part connecting beam 6, a pushing beam 7 and a stop beam 8 are provided on the top of the workbench 1, a limiting groove 9 is provided on the top of the workbench 1, two fixed plates 10 are fixedly connected to the bottom of the workbench 1, and a two-way threaded rod 11 is rotatably connected to the opposite side of the two fixed plates 10, and a movable plate 12 is sleeved on the outer surface of the two-way threaded rod 11, and a buffer mechanism 13 is provided on one side of the movable plate 12, and a positioning plate 14 is provided at one end of the buffer mechanism 13, and a driving motor 15 is fixedly installed on one side of one of the fixed plates 10, and the output end of the driving motor 15 passes through one of the fixed plates 10 and is fixedly connected to the smooth end of the two-way threaded rod 11.

[0022] The effect achieved by the entire embodiment 1 is as follows: by hoisting the two pre-welded component main beams 3 to the top of the rotating mechanism 2, and then starting the drive motor 15, the drive motor 15 drives the bidirectional threaded rod 11 to rotate. Since the limit groove 9 limits the movable plate 12, the bidirectional threaded rod 11 drives the two movable plates 12 to move relative to each other, thereby driving the two positioning plates 14 to move relative to each other, which is convenient for positioning the two component main beams 3 so that the end faces of the two component main beams 3 are at the same level. Then, by starting the reverse direction of the drive motor 15, the two positioning plates 14 are moved to the initial position, and then the two component connecting beams 6 are placed in a position close to the end faces of the two component main beams 3 and perpendicular to the component main beams 3, and then the component support beam 4 is inserted into the hole opened on the component main beam 3. The component support beam 4 is the same length as the component connecting beam 6. Finally, through the pushing mechanism 5, the push beam 7 is pushed forward, and the push beam 7 pushes the component connecting beam 6 to move forward at the same time until it hits the stop beam 8. Then, the connection between the component support beam 4 and the component main beam 3 is spot welded to complete the positioning, and then all parts are fully welded to complete the processing.

[0023] Example 2, as Figure 1 - Figure 4 As shown, the rotating mechanism 2 includes two support plates 201, which are fixedly connected to the top of the workbench 1, and the opposite sides of the two support plates 201 are rotatably connected with rollers 202. The pushing mechanism 5 includes a mounting plate 501, which is fixedly connected to the top of the workbench 1, and an electric push rod 502 is fixedly installed on one side of the mounting plate 501. The telescopic end of the electric push rod 502 is movably passed through the mounting plate 501, and the telescopic end of the electric push rod 502 is fixedly connected to a push plate 503. The buffer mechanism 13 includes a sleeve 131, which is fixedly connected to one side of the movable plate 12, and a return spring 132 is fixedly connected in the sleeve 131. A slide plate 133 is slidably connected in the sleeve 131. One end of the slide plate 133 is fixedly connected to the return spring 132, and one end of the slide plate 133 is fixedly connected to a movable rod 134, which movably passes through the sleeve 131.

[0024] The effect achieved by the entire embodiment 2 is that, by providing a rotating mechanism 2, it is convenient to position the two part main beams 3, and then by providing a pushing mechanism 5, the electric push rod 502 is started, so that the electric push rod 502 drives the push plate 503 to move forward, which is convenient for pushing the push beam 7 forward, and then by providing a buffer mechanism 13, when the two positioning plates 14 move relative to each other to position the two part main beams 3, the positioning plates 14 are subjected to force, so that the movable rod 134 drives the slide plate 133 to slide, and the return spring 132 is squeezed by the slide plate 133 and begins to shrink. Under the action of the elastic force of the return spring 132, it plays a buffering role to avoid excessive clamping force when positioning the part main beam 3 and causing damage to it.

[0025] Working principle: When in use, the two pre-welded component main beams 3 are hoisted onto the plane formed by the tops of multiple rollers 202 on the workbench 1, and then the drive motor 15 is started, so that the drive motor 15 drives the bidirectional threaded rod 11 to rotate. Since the limiting groove 9 limits the movable plate 12, the bidirectional threaded rod 11 drives the two movable plates 12 to move relative to each other, thereby driving the two positioning plates 14 to move relative to each other, and positioning the two component main beams 3. When positioning the two component main beams 3, the positioning plate 14 is subjected to force, so that the movable rod 134 drives the slide plate 133 to slide, and the return spring 132 is squeezed by the slide plate 133 and begins to shrink. Under the elastic force of the return spring 132, it plays a buffering role to avoid clamping when positioning the component main beam 3. Excessive force causes damage to it, so that the end faces of the two part main beams 3 are at the same level. Then, by starting the drive motor 15 to reverse, the two positioning plates 14 are moved to the initial position, and then the two part connecting beams 6 are placed in a position that is close to the end faces of the two part main beams 3 and perpendicular to the part main beam 3. Then, the part support beam 4 is inserted into the hole opened on the part main beam 3. The part support beam 4 and the part connecting beam 6 are the same length. Finally, the electric push rod 502 is started, so that the electric push rod 502 drives the push plate 503 to move forward, pushing the push beam 7 forward, and the push beam 7 pushes the part connecting beam 6 and the part support beam 4 forward at the same time until they hit the stop beam 8. Then, the connection between the part support beam 4 and the part main beam 3 is spot welded to complete the positioning, and then all places are fully welded to complete the processing.
