[0022] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0023] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0024] See also Figure 1 The present application provides a semi-trailer longitudinal beam assembly platform 1, which includes an assembly platform body 11. The assembly platform body 11 includes a loading platform 111 and positioning grooves 112 arranged on both sides of the loading platform 111. In this embodiment, a plurality of power-assisted flipping mechanisms 2 are respectively arranged on both sides of the assembly platform body 11, and the plurality of power-assisted flipping mechanisms 2 are arranged at intervals on the outer sides of the positioning grooves 112 along the length direction of the loading platform 111.

[0025] Specifically, see Figure 2 and Figure 3 The power-assisted flipping mechanism 2 includes a base 21, a flipping member 22, a power unit 23 and an adsorption unit 24. The base 21 is mounted on the outside of the positioning groove 112. The flipping member 22 is rotatably mounted on the base 21, and the axis of rotation is parallel to the length direction of the stage 111. The power unit 23 is fixed on the base 21, and the power unit 23 is connected to the flipping member 22 to drive the flipping member 22 to rotate. The adsorption unit 24 includes an adsorption member 241 for adsorbing and fixing the wing plate. The adsorption unit 24 is suspended on the flipping member 22 and can approach or move away from the stage 111 as the flipping member 22 rotates. When the adsorption unit 24 approaches the stage 111, the adsorption member 241 adsorbs and fixes the wing plate placed on the stage 111; when the adsorption unit 24 moves away from the stage 111, the adsorption member 241 drives the wing plate to move toward the positioning groove 112, and the wing plate falls vertically into the positioning groove 112 under the action of its own gravity.

[0026] The flip member 22 of this embodiment includes a connecting rod portion 221 and a mounting portion 222. The mounting portion 222 is formed by extending outward from the bottom of the connecting rod portion 221 close to the side of the stage 111, and the outer contour of the mounting portion 222 is roughly triangular.

[0027] In this embodiment, the top end of the connecting rod 221 is connected to the adsorption unit 24, and the bottom end is fixedly connected to the power unit 23. The mounting portion 222 is rotatably mounted on the base 21 via the rotating shaft 224, and a through hole for the rotating shaft 224 to pass through is provided at a corresponding position of the mounting portion 222. In this embodiment, the rotating shaft 224 is penetrated on the base 21, and the axial direction of the rotating shaft 224 is parallel to the length direction of the stage 111.

[0028] Furthermore, an inwardly curved concave surface is formed between the mounting portion 222 and the connecting rod portion 221, so that the flip member 22 can accommodate the adsorption unit 24. When the power-assisted flip mechanism 2 is in a non-working state, the adsorption unit 24 suspended from the top of the connecting rod portion 221 is accommodated in the flip member 22, so as to avoid interference between the adsorption unit 24 and other components of the power-assisted flip mechanism 2 or the longitudinal beam of the semi-trailer.

[0029] In this embodiment, the flip member 22 includes two connecting plates 220 disposed opposite to each other, and each connecting plate 220 includes a connecting rod portion 221 and a mounting portion 222. The flip member 22 is composed of two connecting plates 220, which can not only ensure the overall structural strength of the flip member 22, but also help to reduce the weight of the flip member 22.

[0030] The top and bottom of the two connecting plates 220 are fixed by connecting rods 223 to make the interior of the flip member 22 hollow. The two ends of the connecting rod 223 are respectively fixed to the inner surfaces of the two connecting plates 220, and the connecting rod 223 at the bottom is used to connect with the power unit 23.

[0031] Furthermore, the adsorption unit 24 is suspended at the top of the connecting rod 221 by a flexible suspension member 25, and the flexible suspension member 25 is kept in a vertical state under the gravity of the adsorption unit 24. When the adsorption unit 24 falls onto the stage 111 and the stage 111 bears its gravity, the flexible suspension member 25 that can be bent arbitrarily allows the adsorption unit 24 to adjust its position, thereby facilitating the adsorption and fixation of the adsorption member 241 and the wing plate.

[0032] In this embodiment, the flexible hanging member 25 is a chain. The chain is formed by connecting a plurality of chain links in sequence, and the chain links at both ends of the chain are respectively fixedly connected to the connecting rod 221 and the adsorption unit 24. It should be noted that in some other preferred embodiments, the flexible hanging member 25 can also be a rope, a chain, etc.

[0033] Furthermore, in the adsorption unit 24 of the present embodiment, the adsorption member 241 is an electromagnet, and the adsorption member 241 is in a block shape. The adsorption member 241 is energized to be magnetic. Since the wing plate of the longitudinal beam of the semi-trailer is made of metal material, the adsorption member 241 after being energized will have a magnetic adsorption effect when it contacts the wing plate, so that the wing plate is adsorbed and fixed on the adsorption unit 24. After the wing plate falls vertically into the positioning groove 112, the adsorption member 241 is powered off and demagnetized to disconnect the adsorption connection with the wing plate.

[0034] The adsorption unit 24 of this embodiment further includes a mounting seat 242, and the adsorption member 241 is fixed on the surface of the mounting seat 242 facing the stage 111. In this embodiment, the mounting seat 242 is suspended on the top of the connecting rod 221 through a chain.

[0035] Specifically, a chain is provided at the top of each of the two connecting plates 220 of the connecting rod portion 221, and the ends of the two chains are fixedly connected to the mounting seat 242. The positions where the two chains are connected on the mounting seat 242 are symmetrically arranged on both sides of the top of the mounting seat 242, so as to facilitate the position adjustment of the adsorption unit 24 when it is close to the stage 111, so that the surface of the block-shaped adsorption member 241 fits with the wing plate, thereby stably adsorbing and fixing the wing plate on the adsorption unit 24.

[0036] Furthermore, the power unit 23 of the present embodiment is a cylinder, including a cylinder body 231 and a telescopic rod 232 arranged on the cylinder body 231. The cylinder body 231 is mounted on the base 21, and the telescopic rod 232 can be extended and retracted in a direction perpendicular to the loading platform 111. In the present embodiment, the power unit 23 is arranged below the flip member 22, and the connecting rod 223 at the bottom of the connecting rod portion 221 in the flip member 22 is fixedly connected to the top of the telescopic rod 232. This arrangement can reduce the space occupied by the power-assisted flipping mechanism 2 on both sides of the assembly platform body 11, which helps to reduce the overall volume of the semi-trailer longitudinal beam assembly platform 1.

[0037] During actual operation, when the telescopic rod 232 is extended in a direction perpendicular to the stage 111, the telescopic rod 232 drives the flip member 22 to rotate, thereby driving the adsorption unit 24 to approach the stage 111, so that the adsorption member 241 adsorbs and fixes the wing plate placed on the stage 111; when the telescopic rod 232 is retracted in a direction perpendicular to the stage 111, the telescopic rod 232 drives the flip member 22 to rotate, thereby driving the adsorption unit 24 to move away from the stage 111, so that the adsorption member 241 drives the wing plate to move toward the positioning groove 112.

[0038] Preferably, the connection point between the connecting rod 223 and the telescopic rod 232 is the first connection point, the connection point between the connecting rod portion 221 and the adsorption unit 24 is the second connection point, and the connection point between the mounting portion 222 and the base 21 is the third connection point. The angle between the line connecting the first connection point and the second connection point and the line connecting the first connection point and the third connection point is an acute angle. This arrangement can effectively reduce the stroke of the cylinder while ensuring the normal operation of the power-assisted flipping mechanism 2, thereby reducing the space occupied by the power-assisted flipping mechanism 2 when it is working.

[0039] In addition, a mounting plate 26 is provided on one side of the base 21 of the present embodiment, which is close to the loading platform 111. The mounting plate 26 is screwed and fixed to the outer side of the assembly platform body 11, so as to realize the installation of the power-assisted flipping mechanism 2 on the semitrailer longitudinal beam assembly platform 1. In the present embodiment, a protective cover 27 is provided on the side of the base 21 which is away from the loading platform 111. The protective cover 27 is arranged close to the flipping member 22 to isolate the operator from the flipping member 22, so as to prevent the worker from being pinched when the power-assisted flipping mechanism 2 is working.

[0040] When the semi-trailer longitudinal beam assembly platform 1 of the present embodiment is used to assemble the flange and web of the longitudinal beam, the flange and web to be assembled are placed horizontally on the loading platform 111. The power-assisted flipping mechanism 2 on both sides of the assembly platform body 11 is activated, so that the telescopic rod 232 of the power unit 23 is extended in a direction perpendicular to the loading platform 111 to rotate the flipping member 22, and the adsorption unit 24 moves toward the loading platform 111 along with the rotating flipping member 22, so that the energized electromagnet adsorbs and fixes the flange placed on the loading platform 111; after the adsorption member 241 is adsorbed and fixed to the flange, the telescopic rod 232 of the power unit 23 is retracted in a direction perpendicular to the loading platform 111, and the adsorption unit 24 gradually moves away from the loading platform 111 along with the rotation of the flipping member 22, so that the adsorption member 241 drives the flange to move toward the positioning groove 112. When the wing plate moves toward the positioning groove 112, due to its own gravity, the wing plate will vertically fall into the positioning groove 112 after the electromagnet is powered off, so as to stand on both sides of the web.

[0041] For the semi-trailer longitudinal beam assembly platform 1 of this embodiment, a clamping mechanism can be provided on both sides of the assembly platform body 11 to clamp the web and the wing plates erected on both sides of the web, so as to facilitate the subsequent spot welding operation. In addition, a lifting roller can be provided on the assembly platform body 11, and the lifting roller is used to transport the wing plates and web plates to be assembled and the semi-trailer longitudinal beam after assembly. When the wing plates and web plates are transported to the right place, the lifting roller falls down to make the wing plates and web plates fall on the upper surface of the loading platform 111; after the wing plates and web plates are assembled and welded and fixed, the lifting roller rises to transport the semi-trailer longitudinal beam to the next workbench position.

[0042] In summary, for the semi-trailer longitudinal beam assembly platform of this embodiment, the wing plates can be erected on both sides of the web plate through the power-assisted flipping mechanism on both sides of the assembly platform body. Among them, the adsorption member is used to adsorb and fix the wing plate, and the power unit and the flipping member work together to provide assistance, so that the wing plate moves toward the positioning groove, so that it falls vertically into the positioning groove under its own gravity, so as to realize the erection of the wing plate on both sides of the web plate. The whole process only requires one operator to control, which effectively reduces the labor intensity of the workers, and to a certain extent improves the work efficiency of longitudinal beam assembly, reducing the probability of industrial accidents.
