[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0040] like Figures 1 to 11 As shown, the transfer vehicle for intelligent manufacturing workshops according to the present invention is specifically as follows:

[0041] It includes a trackless transfer vehicle 1; the trackless transfer vehicle 1 is provided with a placement mechanism 2; a counterweight 11 is installed at the rear of the trackless transfer vehicle 1; a mounting slot 12 is provided at the front of the trackless transfer vehicle 1, located inside the trackless transfer vehicle 1; right-angle mounting plates 13 are fixedly connected to the end surfaces of both sides of the trackless transfer vehicle 1 below the mounting slot 12; and first servo motors 14 are fixedly connected to the end surfaces of the two right-angle mounting plates 13 on opposite sides.

[0042] The placement mechanism 2 includes a drive shaft 21; the drive shaft 21 rotates in the mounting groove 12, and the two ends of the drive shaft 21 extend out of the mounting groove 12; the rotating shafts on the two first servo motors 14 are fixedly connected to the drive shaft 21 through a coupling;

[0043] The drive shaft 21 is provided with a flat surface, which is initially perpendicular to the ground. Two mounting seats 22 are fixedly mounted on the flat surface of the drive shaft 21. A lead screw 23 is rotatably connected to the two mounting seats 22, and the threads on the lead screw 23 are opposite to each other with the center line of the lead screw 23 as the dividing line.

[0044] A first gear 24 is fixedly connected to the lead screw 23 between the two mounting seats 22; a chamber is defined in the drive shaft 21, and a second servo motor 25 is installed in the chamber; a second gear 26 is fixedly connected to the rotating shaft of the second motor, and the second gear 26 is meshed with the first gear 24;

[0045] A lifting plate 27 is provided on each of the lead screws 23 on opposite sides of the two mounting seats 22, and the lifting plates 27 are threadedly engaged with the lead screws 23; the end of the lifting plate 27 away from the drive shaft 21 is parallel to the ground, and the end close to the drive shaft 21 is tilted upward; a first sliding groove 28 is defined on the plane of the drive shaft 21; a first slider 29 is fixedly connected to the side of the lifting plate 27 close to the drive shaft 21, and the first slider 29 slides in the first sliding groove 28;

[0046] A rectangular groove 3 is provided inside the trackless transfer vehicle 1; a support plate 31 is rotatably connected to the rectangular groove 3 via a pin; an electric telescopic rod 32 is installed in the rectangular groove 3, and the other end of the electric telescopic rod 32 is hinged to the support plate 31; the upper surface of the support plate 31 is a V-shaped surface; the upper surface of the trackless transfer vehicle 1 opposite to the first gear 24 of the support plate 31 is also a V-shaped surface;

[0047] The V-shaped surface on the upper surface of the support plate 31 and the V-shaped surface on the upper surface of the trackless transfer vehicle 1 are rotatably connected with two rows of evenly arranged rollers 33;

[0048] During operation, when the trackless transfer vehicle 1 is used to transfer steel coils or cylindrical goods, the staff controls the trackless transfer vehicle 1 to move in front of the goods to be transferred. At this time, the two lifting plates 27 on the screw 23 are located on both sides of the goods. Then the staff stops the trackless transfer vehicle 1 and continues to move. Then the second servo motor 25 is controlled to run. Then the second gear 26 rotates following the second servo motor 25. The first gear 24 engaged with the second gear 26 rotates under the drive of the first gear 24, thereby driving the screw 23 to rotate in the mounting seat 22. At the same time, The lifting plates 27 threadedly engaged with the lead screw 23 move closer to each other, and at the same time, the first slider 29 fixed to the lifting plates 27 slides in the first slide groove 28 provided in the drive shaft 21. As the two lifting plates 27 approach each other, they gradually come into contact with the cylindrical surface of the steel coil or cylindrical cargo. After the lifting plates 27 come into contact with the cargo, the two lifting plates 27 continue to move closer to each other and squeeze the cylindrical surface of the cargo. As the lifting plates 27 gradually squeeze the cargo, the cargo is gradually squeezed between the two lifting plates 27, and then the second servo motor 25 is controlled to stop running.

[0049] Subsequently, the staff controls the first servo motor 14 to operate, and the first servo motor 14 rotates slowly, and at the same time drives the drive shaft 21 to rotate slowly. Since the lifting plate 27 slides in the first slide groove 28 of the drive shaft 21 through the first slider 29, during the rotation of the drive shaft 21, it drives the first servo motor 14, the lead screw 23 and the lifting plate 27 to rotate slowly upward with the midpoint of the drive shaft 21 as the center of the circle. At the same time, the lifting plate 27 slowly drives the goods to rotate upward, thereby gradually tilting the goods. When the goods are tilted, the goods will slide from the high position of the lifting plate 27 to the low position until the goods move to the trackless transfer vehicle 1 When the cargo slides to the upper surface of the trackless transfer vehicle 1, the bottom of the cylindrical cargo will first contact the roller 33 on the V-shaped surface on the upper surface of the trackless transfer vehicle 1, and then continue to move. When the cargo completely leaves the lifting plate 27 and moves onto the trackless transfer vehicle 1, the cargo will move on the roller 33 and finally stop on the V-shaped surface of the support plate 31. Due to the presence of the counterweight 11, the center of gravity of the trackless transfer vehicle 1 can be prevented from being unstable and lifted. Then, when the drive shaft 21 rotates ninety degrees and stops rotating, the lifting plate 27 and the upper surface of the trackless transfer vehicle 1 are in a vertical state, and then the transfer can be carried out.

[0050] When the goods are transferred, due to the presence of the V-shaped surface, the center of gravity of the goods can be located at the lowest point of the support plate 31, thereby reducing the tendency of the goods to roll. At the same time, since the lifting plate 27 is perpendicular to the upper surface of the trackless transfer vehicle 1, the vertical lifting plate 27 can be used to block the goods, preventing the goods from moving forward when the trackless transfer vehicle 1 brakes, thereby separating from the trackless transfer vehicle 1. At the same time, due to the presence of the lifting plate 27, the trackless transfer vehicle 1 can be protected, preventing the trackless transfer vehicle 1 from hitting other things when moving, thereby protecting the trackless transfer vehicle 1 body. At the same time, since the lifting plate 27 is perpendicular to the upper surface of the trackless transfer vehicle 1, the highest point of the lifting plate 27 is higher than the goods. When the trackless transfer vehicle 1 is running, the staff can see the lifting plate 27 first, thereby playing a warning role, preventing the trackless transfer vehicle 1 from colliding with the staff who have not seen the trackless transfer vehicle 1 when turning, and unloading can be carried out when the trackless transfer vehicle 1 is transferred to the destination.

[0051] When unloading, the staff controls the lifting plate 27 to gradually rotate ninety degrees in the opposite direction, and controls the electric telescopic rod 32 to extend, thereby pushing the support plate 31 to rotate, and at the same time pushing the goods to gradually tilt. The tilted goods will move on the roller 33 on the V-shaped surface, and then the goods will slide between the two lifting plates 27. In the process of reverse rotation of the lifting plates 27, the side of the lifting plate away from the trackless transfer vehicle 1 will gradually become parallel to the ground. At this time, the goods will gradually slide downward on the lifting plates 27 until they slide to the bottom of the lifting plates 27. Then the second motor is controlled to reverse to drive the lifting plates 27 away from each other, thus completing the transfer of the goods.

[0052] In the above operation process, there is no need to use auxiliary tools to transfer the goods to the trackless transfer vehicle 1, and there is no need to manually carry the goods to the trackless transfer vehicle 1, thereby reducing manpower and financial costs. At the same time, when unloading, the goods can be unloaded without the help of tools or manpower;

[0053] When the trackless transfer vehicle 1 needs to transfer the goods placed on the vehicle, the trackless transfer vehicle 1 is moved to the vehicle door, and then the lifting plate 27 is controlled to rotate with the center line of the drive shaft 21 as the center. When the lifting plate 27 is rotated away from one end of the trackless transfer vehicle 1 to be flush with the surface of the vehicle, the staff can push the goods between the two lifting plates 27. When pushing the goods, the bottom surface of the goods is directed toward between the two lifting plates 27. When the goods are pushed between the two lifting plates 27, continue to slowly rotate and lift, so that the goods gradually slide onto the trackless transfer vehicle 1. In this process, the goods on the vehicle can be directly transferred without unloading the goods from the vehicle before transfer.

[0054] The specific embodiment further includes a limiting mechanism 4; the limiting mechanism 4 includes two limiting plates 41; the two limiting plates 41 are respectively arranged at two sides of the rectangular groove 3; a second sliding groove 42 is opened on both sides of the rectangular groove 3; a second slider 43 is fixedly connected to the bottom of the two limiting plates 41, and the second slider 43 is slidably connected to the second sliding groove 42; the second slider 43 is connected to the second sliding groove 42 by a spring;

[0055] The V-shaped surface of the support plate 31 is hinged with a baffle 44 via a pin, and the other ends of the two baffles 44 extend to the opposite side of the limit plate 41;

[0056] In a specific embodiment, the two baffles 44 are located on one side of the end surface facing the support plate 31, and the inner wall of the baffle 44 is slidably connected to a baffle rod 45 through a spring, and when the baffle rod 45 is squeezed, it will slide into the baffle 44;

[0057] During operation, when the goods gradually leave the lifting plate 27 and slide onto the trackless transfer vehicle 1, the goods will move between the two limit plates 41. The existence of the limit plate 41 can limit the goods and prevent the goods from rolling on the trackless transfer vehicle 1. At the same time, since the second sliding block 43 fixedly connected to the limit plate 41 slides in the second sliding groove 42, the distance between the two limit plates 41 can be adjusted, so that it can be suitable for goods of different diameters. When the goods move to the tail of the support plate 31, the two baffles 44 will be squeezed. After being squeezed, the baffles 44 will rotate, so that the baffles 44 will contact the limit plates 41. At the same time, since the baffles 44 are provided with evenly arranged baffles 45, the baffles 45 can limit the limit plates 41, thereby further improving the fixation of the goods. At the same time, the existence of the baffles 44 can block the goods and prevent them from sliding down from the rear of the trackless transfer vehicle 1.

[0058] In a specific embodiment, the surfaces on the opposite sides of the two lifting plates 27 are arc surfaces;

[0059] Ball bearings are rotatably connected on the arc surfaces of the two lifting plates 27;

[0060] During operation, since the opposite sides of the two lifting plates 27 are arc surfaces, the lifting plates 27 can better fit the cylindrical surface of the goods. At the same time, since the lifting plates 27 are rotatably connected with evenly arranged balls, the presence of the balls can reduce the friction between the goods and the lifting plates 27.

[0061] In a specific embodiment, the side of the limit plate 41 facing the lead screw 23 is bent outward;

[0062] During operation, since the limit plate 41 bends outward toward one side of the lead screw 23, the goods can be guided when they are moved onto the trackless transfer vehicle 1. At the same time, it can also prevent the goods from being too large in diameter and unable to move between the two limit plates 41.

[0063] In a specific embodiment, a gap is left between the V-shaped surface on the upper surface of the support plate 31 and the two rows of rollers 33 on the V-shaped surface on the upper surface of the trackless transfer vehicle 1;

[0064] During operation, since there is a gap between the two rows of rollers 33, the center of gravity of the goods can be placed between the two rows of rollers 33, reducing the tendency of the goods to roll.

[0065] In a specific embodiment, both ends of the lead screw 23 are provided with a retaining ring 231, and the retaining ring 231 is threadedly connected to the lead screw 23;

[0066] Specifically, since retaining rings 231 are provided on both sides of the lead screw 23 , the presence of the retaining rings 231 can enable the lifting plate 27 to rotate out of the lead screw 23 .

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments.
