DETAILED DESCRIPTION
[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.
[0021] As Figure 1 And Figure 2 The utility model provides a kind of AGV electric flatcar of table surface can be lifted technical scheme, including platform car body 1, platform car body 1 upper end is equipped with table body 2, table body 2 is equipped with sliding slot 3, table body 2 is equipped with push plate 4 in sliding installation, platform car body 1 is equipped with lifting mechanism 5 in installation, platform car body 1 is equipped with unloading mechanism 6, by the cooperation of use of lifting mechanism 5 and unloading mechanism 6, the height of table can be adjusted, and unloading can be conveniently carried out.
[0022] As Figure 2 And Figure 3As shown, the lifting mechanism 5 includes a rear row of oil cylinders 502 fixedly installed at the rear end of the platform car body 1 and a front row of oil cylinders 501 rotatably installed at the edge of the front end of the platform car body 1, a driving screw rod 506 rotatably installed at the bottom of the platform car body 1, a screw nut 504 threadedly installed on the driving screw rod 506, and the screw nut 504 is fixed on the push plate 4, the front row of oil cylinders 501 and the rear row of oil cylinders 502 are each provided with a hinged seat 505, the front row of oil cylinders 501 is fixedly installed with a fixed leg 503 at the bottom, the platform car body 1 is provided with a positioning groove at the bottom, and the rear row of oil cylinders 502 is installed on the platform car body 1 through the positioning groove.
[0023] Specifically, through the precise control system, synchronous control of the front row of oil cylinders 501 and the rear row of oil cylinders 502 can be realized, so that the two oil cylinders can be extended in coordination. When the two oil cylinders are synchronously extended, they will jointly act on the table body 2 to push it to move upward, thereby realizing fine adjustment of the height of the table. In addition, the front row of oil cylinders 501 can be controlled to perform the extension action alone. When only the front row of oil cylinders 501 is extended, the table body 2 will rotate with the upper end of the rear row of oil cylinders 502 as the rotation axis. This rotating action will cause the table body 2 to tilt backward, so that the goods placed on the table can automatically slide down by the action of gravity, greatly simplifying the unloading process and improving the work efficiency.
[0024] As shown in Figure 2 and Figure 4 The unloading mechanism 6 includes a motor 601 and a retaining frame 610 fixedly installed on the platform car body 1, a driving shaft 606 fixedly installed at the output end of the motor 601, an adjusting shaft 609 rotatably installed on the retaining frame 610, a worm gear 608 fixedly installed on the adjusting shaft 609, a worm 607 rotatably installed below the worm gear 608, and the worm 607 is fixedly installed at the end of the driving shaft 606, a positioning shaft 507 is arranged below the driving screw rod 506 and above the driving shaft 606, a telescopic transmission shaft 603 is arranged between the positioning shafts 507, universal joints 602 are arranged at both ends of the telescopic transmission shaft 603, bevel gears 604 are arranged on the driving screw rod 506, the positioning shaft 507 and the driving shaft 606, and the bevel gears 604 are meshed with each other, clutches 605 are arranged on the positioning shaft 507 and the driving shaft 606, a bearing is arranged on the retaining frame 610, the adjusting shaft 609 is rotatably installed in the retaining frame 610 through the bearing, and the front row of oil cylinders 501 is fixed on the adjusting shaft 609 through the fixed leg 503
[0025] Specifically, the rotation of the drive shaft 606 will drive the worm 607 to rotate. The rotation of the worm 607 will further be transmitted to the worm gear 608, so as to drive the adjusting shaft 609 on the worm gear 608 to rotate. The rotation of the adjusting shaft 609 can adjust the angle of the front oil cylinder 501. This adjustment ensures that the mesa body 2 will not be stuck during rotation. When the clutch 605 on the positioning shaft 507 is in the engaged state, the rotation of the drive shaft 606 can be effectively transmitted to the telescopic transmission shaft 603. The rotation of the telescopic transmission shaft 603 will drive the drive screw 506 to rotate. The rotation of the drive screw 506 causes the nut 504 to move forward, and the forward movement of the nut 504 will push the push plate 4 to move forward. Finally, the forward movement of the push plate 4 can push the material adhering to the mesa body 2 down, significantly improving the unloading effect.
[0026] Working principle: When in use, the front oil cylinder 501 and the rear oil cylinder 502 can be controlled to extend synchronously. After the front oil cylinder 501 and the rear oil cylinder 502 extend synchronously, they will drive the mesa body 2 to move upward, thereby adjusting the height of the mesa. Only the front oil cylinder 501 can be extended, and when only the front oil cylinder 501 is extended, the mesa body 2 will rotate with the upper end of the rear oil cylinder 502 as the center, thereby making the mesa body 2 tilt backward, so that the goods on the mesa body 2 automatically slide down, facilitating unloading. During the rotation of the mesa body 2, the motor 601 can be started. After the motor 601 is started, it will drive the drive shaft 606 to rotate. After the drive shaft 606 rotates, it will drive the worm 607 to rotate. After the worm 607 rotates, it will drive the adjusting shaft 609 on the worm gear 608 to rotate, thereby adjusting the angle of the front oil cylinder 501 during the rotation of the mesa body 2, so that the mesa body 2 is not stuck during rotation. At the same time, the clutch 605 on the positioning shaft 507 can be controlled to be in the engaged state. When the clutch 605 on the positioning shaft 507 is in the engaged state, the drive shaft 606 can drive the telescopic transmission shaft 603 to rotate. When the telescopic transmission shaft 603 rotates, it will drive the drive screw 506 to rotate. When the drive screw 506 rotates, it will drive the nut 504 to move forward. When the nut 504 moves forward, it will drive the push plate 4 to move forward, thereby pushing the material adhering to the mesa body 2 down, improving the unloading effect.
