[0036] refer to Figure 1 and Figure 2 A layered picker includes a fixed frame 11, a connecting frame 21 and a plurality of clamping arms 31.
[0037] The connecting frame 21 is installed on the fixed frame 11, the connecting frame 21 is fixedly connected to the connecting seat 15, the connecting seat 15 is fixedly connected to the connecting rod 12, the fixing frame 11 is fixedly connected to the connecting sleeve 13, and the connecting sleeve 13 is slidably connected to the connecting rod 12. A telescopic driving member 14 is provided between the fixing frame 11 and the connecting frame 21 to realize the function of driving the connecting frame 21 to move relative to the fixing frame 11. The telescopic driving member 14 is a hydraulic cylinder whose two ends are respectively fixedly connected to the fixing frame 11 and the connecting frame 21, and realizes the function of the telescopic driving member 14 driving the connecting frame 21 to move.
[0038] The connecting frame 21 is fixedly connected with a plurality of guide sleeves 32, and the clamping arm 31 is fixedly connected with a guide rod 33. The guide rod 33 is slidably connected with the guide sleeve 32. The plurality of guide sleeves 32 correspond to the guide rods 33 on the plurality of clamping arms 31 one by one. A hydraulic drive mechanism is provided between the connecting frame 21 and the clamping arm 31. The connecting frame 21 is rotatably connected with the synchronous gear 22. The clamping arm 31 is fixedly connected with the synchronous rack 23. The synchronous racks 23 on the plurality of clamping arms 31 are all meshed with the synchronous gear 22. A total of four clamping arms 31 are provided. The four clamping arms 31 are evenly distributed around the circumference with the synchronous gear 22 as the center. The synchronous racks 23 on the two adjacent clamping arms 31 are staggered up and down, and the synchronous racks 23 on the opposite clamping arms 31 are located at the same height. Each clamping arm 31 is provided with a total of two guide rods 33. The synchronous gear 22 is located between the two guide rods 33, which plays a role in improving the stability of the structure.
[0039] refer to Figure 3 and Figure 4The hydraulic drive mechanism includes a central oil pipe 41, a plurality of branch oil cylinders 42, a plurality of piston rods 43 and a plurality of piston blocks 44. The plurality of branch oil cylinders 42 are all connected to the central oil pipe 41. The plurality of piston blocks 44 are respectively connected to the inner walls of the plurality of branch oil cylinders 42 in a sliding manner. The piston rods 43 are fixedly connected to the piston blocks 44. The piston rods 43 extend out of the branch oil cylinders 42 and are fixedly connected to the clamp arms 31. The plurality of piston rods 43 correspond to the plurality of clamp arms 31 one by one. Hydraulic oil is provided in the central oil pipe 41 and the branch oil cylinders 42. The central oil pipe 41 is connected to a first oil pipe interface 45. The branch oil cylinders 42 are connected to a second oil pipe interface 46. The piston blocks 44 are located between the first oil pipe interface 45 and the second oil pipe interface 46. The plurality of branch oil cylinders 42 are evenly distributed around the central oil pipe 41. There are four clamping arms 31, branch oil cylinders 42, piston rods 43 and piston blocks 44, and there is a one-to-one correspondence between the four clamping arms 31, the four branch oil cylinders 42, the four piston rods 43 and the four piston blocks 44. The four clamping arms 31 clamp the goods at the same time, which plays a role in providing stability in clamping the goods.
[0040] The fixing frame 11 is installed on a forklift, and the forklift drives the fixing frame 11, the connecting frame 21 and the clamping arms 31 to move, so that the goods are located between the multiple clamping arms 31, and the hydraulic drive mechanism drives the multiple clamping arms 31 to move. The movement direction of the clamping arms 31 is guided by the setting of the guide rod 33 and the guide sleeve 32, so that the multiple clamping arms 31 are brought close to each other and clamp the goods, thereby realizing the function of clamping the goods.
[0041] This embodiment has the following advantages:
[0042] When the hydraulic drive mechanism drives the multiple clamping arms 31, the synchronous rack 23 drives the synchronous gear 22 to rotate. During the rotation, the synchronous gear 22 restricts the multiple synchronous racks 23 to move at the same speed, so that the multiple clamping arms 31 can move at the same speed, thereby improving the stability of the layered sorter during movement, and enabling the geometric center of the goods to be located at the center position of the layered picker after the goods are clamped, thereby preventing the forklift from tipping over during the transportation of goods, thereby achieving the advantage of better safety.
[0043] The hydraulic oil in the central oil pipe 41 is pumped out to generate negative pressure in the central oil pipe 41, driving multiple piston blocks 44 to move toward the central oil pipe 41 at the same time. The piston blocks 44 drive the piston rods 43 to move, thereby realizing the function of driving multiple clamping arms 31 to move at the same time.
[0044] Hydraulic oil is extracted from the first oil pipe interface 45 to realize the function of extracting the hydraulic oil in the central oil pipe 41. Hydraulic oil is injected into the second oil pipe interface 46 to generate positive pressure on the side of the piston block 44 away from the central oil pipe 41, pushing the piston block 44 to move toward the central oil pipe 41, which can increase the thrust on the piston block 44, thereby increasing the clamping force of the clamp arm 31 on the cargo through the piston rod 43.
[0045] The branch oil cylinders 42 evenly distributed around the circumference can make the hydraulic drive mechanism more balanced and uniform in force, thereby improving the stability of the hydraulic drive mechanism.
[0046] By sliding the connecting rod 12 on the connecting sleeve 13, the connecting seat 15 and the connecting frame 21 can move relative to the fixing frame 11, so as to adjust the position of the connecting frame 21 and facilitate the transportation of goods.
[0047] Adjacent synchronous racks 23 are staggered up and down, which prevents adjacent synchronous racks 23 from colliding with each other, making the overall structure more compact.
[0048] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
