Description

Technical Field

[0001] This utility model specifically relates to the field of warehouse robot technology, and more specifically to an intelligent forklift robot used for stacking goods. Background Technology

[0002] Intelligent forklift robots are devices that integrate advanced intelligent technologies into traditional forklifts, enabling them to operate automatically and intelligently. They can automatically complete tasks such as picking up, moving, and stacking goods according to preset instructions, without the need for direct human operation. This significantly improves work efficiency and accuracy, reduces labor costs, and is used in warehouses, logistics centers, and other places for the processes of receiving, storing, inventorying, and shipping goods, achieving efficient handling and precise management of goods, and improving the utilization rate of warehouse space and the efficiency of logistics operations.

[0003] However, in practice, it has been noted that due to the limited warehouse area, with most of the space used for storing goods and limited aisles between goods, and the fact that most forklifts are quite long, space is needed to adjust the orientation of the forks when picking up or stacking goods. For goods in narrow aisles, the forklifts can only be transported nearby and then stacked manually, which is labor-intensive and greatly affects the efficiency of stacking. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent forklift robot for stacking goods. Through a steering mechanism connecting the support frame and a lateral adjustment mechanism, the orientation of the forks can be adjusted, enabling stacking and retrieving of goods in relatively narrow aisles that are only accessible by forklifts. This solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The intelligent forklift robot for stacking goods includes a forklift moving part and a forklift lifting part, and a lateral adjuster and a steering linkage are movably connected between the forklift moving part and the forklift lifting part.

[0007] The steerable connecting bracket has a steering connecting frame that is fixedly connected to the lifting part of the forklift. The steering connecting frame is triangular in shape, and the end of the steering connecting frame near the lateral adjuster is semi-circular.

[0008] Furthermore, the steering connecting frame has a fixed gear ring arranged in a ring array at one end, which is semi-circular. The side of the fixed gear ring is connected to a drive gear, and the drive gear is movably connected to the lateral adjuster.

[0009] As a further technical solution of this utility model, the end of the drive gear passes through the lateral adjuster and is in transmission cooperation with the hydraulic motor fixedly connected to the lateral adjuster.

[0010] Both ends of the steering connecting frame are integrally provided with inclined triangular seats, and each inclined triangular seat is provided with an inclined hydraulic cylinder that is movably connected to the steering connecting frame.

[0011] As a further technical solution of this utility model, the lateral adjuster includes a grooved slide rail fixedly connected to the moving part of the forklift. A longitudinal moving seat is slidably fitted on the side of the grooved slide rail, and a threaded hole is provided in the longitudinal moving seat. A threaded adjusting rod is threadedly fitted in the threaded hole, and both ends of the threaded adjusting rod are movably connected to the grooved slide rail.

[0012] As a further technical solution of this utility model, the end of the longitudinal moving seat away from the groove slide rail is U-shaped, and the end of the steering connecting frame is inserted into the U-shaped longitudinal moving seat. The end of the longitudinal moving seat is fixedly connected to a central shaft, and the central shaft passes through the end of the steering connecting frame.

[0013] As a further technical solution of this utility model, the forklift moving part includes an AGV (Automated Guided Vehicle), the bottom of which is equipped with drive wheels, and the grooved slide rail is embedded in the end of the AGV.

[0014] As a further technical solution of this utility model, the forklift lifting part includes a lifting frame, the lifting frame having a lifting fork frame with lifting forks welded to one end, and a symmetrical lifting hydraulic cylinder fixedly connected to the other end of the lifting fork frame, and a fixed mast also slidingly fitted to the side of the lifting fork frame.

[0015] As a further technical solution of this utility model, the fixed gantry has a limiting slide rail that slides with both ends of the lifting fork frame, and a symmetrical U-shaped reinforcing frame and a connecting stop are welded on the side of the limiting slide rail away from the lifting fork frame.

[0016] Both ends of the connecting bracket are movably connected to the end of the tilting hydraulic cylinder away from the steering connecting bracket, while the bottom of the limiting slide rail is movably connected to the tilting triangular seat via a small rotation; the other end of the lifting hydraulic cylinder is fixedly connected to the limiting slide rail.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, when the hydraulic motor drives the drive gear to rotate, the transmission between the fixed gear ring and the drive gear causes the steering connecting frame to rotate the fixed mast, thereby allowing the forks to move laterally. This enables the forklift robot to pick up goods from the side in locations where turning around is inconvenient, increasing its applicability. Furthermore, the threaded engagement between the threaded adjusting rod and the threaded hole allows the fixed mast to move axially along the longitudinal moving seat. With the forks after steering, it can pick up goods from the side of the AGV (Automated Guided Vehicle), and the longitudinal position of the forks before steering can be adjusted, eliminating the need for frequent adjustments to the AGV's position and improving stacking efficiency. Finally, the steering connecting frame has a shaft hole corresponding to the central shaft at one end near the longitudinal moving seat. The central shaft and the shaft hole at the end of the steering connecting frame are movably connected via bearings, ensuring a smooth connection between the steering connecting frame and the longitudinal moving seat and guaranteeing normal rotation.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 This utility model provides an intelligent forklift robot for stacking goods, including a forklift moving part and a forklift lifting part, and a lateral adjuster 3 and a steerable connecting bracket 4 are movably connected between the forklift moving part and the forklift lifting part.

[0030] The steerable connecting bracket 4 has a steering connecting frame 41 that is fixedly connected to the lifting part of the forklift. The steering connecting frame 41 is triangular in shape, and the end of the steering connecting frame 41 near the lateral adjuster 3 is semi-circular.

[0031] Furthermore, the steering connecting frame 41 is semi-circular, with a fixed gear ring 44 arranged in a ring array at one end. The side of the fixed gear ring 44 is driven by a drive gear 46, and the drive gear 46 is movably connected to the lateral adjuster 3.

[0032] Furthermore, the end of the drive gear 46 passes through the lateral adjuster 3 and is in transmission engagement with the hydraulic motor 45 fixedly connected to the lateral adjuster 3.

[0033] Both ends of the steering connecting frame 41 are integrally provided with inclined triangular seats 42, and each inclined triangular seat 42 is provided with an inclined hydraulic cylinder 43 that is movably connected to the steering connecting frame 41.

[0034] By adopting the above technical solution, when the hydraulic motor 45 drives the drive gear 46 to rotate, the transmission between the fixed gear ring 44 and the drive gear 46 causes the steering connecting frame 41 to drive the fixed mast 5 to turn, thereby causing the forks 7 to move laterally. This allows for the picking up of goods on the side in locations where it is inconvenient to turn around, increasing the applicability of the forklift robot.

[0035] Furthermore, the lateral adjuster 3 includes a grooved slide rail 31 fixedly connected to the moving part of the forklift. A longitudinal moving seat 33 is slidably fitted on the side of the grooved slide rail 31, and a threaded hole 34 is provided in the longitudinal moving seat 33. A threaded adjusting rod 32 is threadedly fitted in the threaded hole 34, and both ends of the threaded adjusting rod 32 are movably connected to the grooved slide rail 31.

[0036] More specifically, the end of the longitudinal moving seat 33 away from the groove slide rail 31 is U-shaped, and the end of the steering connecting frame 41 is inserted into the U-shaped longitudinal moving seat 33. The end of the longitudinal moving seat 33 is fixedly connected to a central shaft 35, and the central shaft 35 passes through the end of the steering connecting frame 41.

[0037] By adopting the above technical solution, the fixed mast 5 can move along the axial direction of the longitudinal moving seat 33 through the threaded engagement between the threaded adjusting rod 32 and the threaded hole 34. With the fork 7 after turning, it can pick up the goods on the side of the AGV automatic guided vehicle 1. Furthermore, the longitudinal position of the fork 7 before turning can be adjusted, eliminating the need for frequent adjustments to the position of the AGV automatic guided vehicle 1, thereby improving the efficiency of stacking.

[0038] Furthermore, the forklift moving part includes an AGV (Automated Guided Vehicle) 1, with drive wheels 2 mounted on the bottom of the AGV 1, and grooved slide rails 31 embedded in the end of the AGV 1.

[0039] Furthermore, the forklift lifting part includes a lifting frame 6, which has a lifting fork 61 with lifting forks 7 welded to one end, and a symmetrical lifting hydraulic cylinder 62 fixedly connected to the other end of the lifting fork 61. A fixed mast 5 is also slidably fitted on the side of the lifting fork 61.

[0040] More specifically, the fixed gantry 5 has a limiting slide rail 52 that slides with both ends of the lifting fork 61. A symmetrical U-shaped reinforcing frame 51 and a connecting baffle 53 are welded to the side of the limiting slide rail 52 away from the lifting fork 61.

[0041] Both ends of the connecting bracket 53 are movably connected to the end of the tilting hydraulic cylinder 43 away from the steering connecting bracket 41, while the bottom of the limiting slide rail 52 is movably connected to the tilting triangular seat 42 through a small circle; the other end of the lifting hydraulic cylinder 62 is fixedly connected to the limiting slide rail 52.

[0042] Furthermore, a drive motor is installed on the inner side of the AGV automated guided vehicle 1 near the lateral adjuster 3, and the drive motor is connected to the end of the threaded adjusting rod 32 through a gear transmission. The drive motor can drive the threaded adjusting rod 32 to rotate inside the grooved slide rail 31.

[0043] Furthermore, each of the aforementioned limiting slide rails 52 is fixedly connected to a universal caster 8. The universal caster 8 shares part of the load acting on the connection between the lateral adjuster 3 and the steerable connecting bracket 4, preventing the connection from being damaged due to excessive force.

[0044] The working principle of this utility model is as follows: In use, the drive wheel 2 at the bottom of the AGV (Automated Guided Vehicle) 1 first pushes the fixed mast 5 to one end of the cargo. Then, the lifting hydraulic cylinder 62 drives the lifting frame 6 to move downwards, lowering the forks 7 fixedly connected to the end of the lifting frame 6. The cargo is then lifted. When the cargo is in a relatively narrow space where the robot cannot turn around, the hydraulic motor 45 drives the steering connecting frame 41 to rotate to the side through the meshing of the drive gear 46 and the fixed gear ring 44. Simultaneously, the threaded adjusting rod 3 in the AGV 1... The drive motor of the transmission connection drives the threaded adjusting rod 32 to rotate. Through the mutual meshing between the threaded adjusting rod 32 and the threaded hole 34, the longitudinal moving seat 33 drives the steerable connecting bracket 4 to move along the axial direction of the threaded adjusting rod 32. This allows for the forklift to pick up goods in confined spaces or inconvenient locations where turning around is difficult. At the same time, the lateral position of the forks 7 can be adjusted without turning, allowing for the stacking and picking up of goods near the edge. This increases the applicability of the forklift. The structure is simple, the operation is very convenient, and the intensity of manual labor is effectively reduced.
