Description

A reach truck AGV Technical Field

[0001] This utility model relates to the field of material handling equipment technology, specifically to a reach truck-type AGV. Background Technology

[0002] In modern logistics and industrial production, forklift-type AGVs are playing an increasingly important role as key equipment for automating material handling. With their automated operation, high-efficiency handling capabilities, and precise positioning, they significantly improve logistics efficiency and reduce labor costs.

[0003] As shown in Figure 1, the utility model patent with authorization announcement number CN206915132U provides a forklift-type AGV, including an AGV body, a vertically movable forklift frame, a drive device for driving the forklift frame, an anti-collision sensor, and a line-following identifier for identifying the travel route. The forklift frame is mounted on the upper surface of the AGV body; the anti-collision sensor is mounted on the side wall of the AGV body; the line-following identifier is mounted on the bottom of the AGV body; and a controller is provided inside the AGV body, which is connected to the anti-collision sensor, the line-following identifier, and the drive device. However, because the forks of this forklift-type AGV are mounted on the top of the AGV body, the installation height and working height of the forks are relatively high. Furthermore, during material handling, the AGV needs to move to a position below a pallet or rack, thus preventing low-level operation; that is, it cannot handle pallets or racks with lower space (below the AGV body), resulting in poor versatility.

[0026] The forks are provided in two pairs, spaced apart along the Y-axis. The first end of each fork is connected to the sliding seat, and the second end extends along the X-axis. The two forks can move closer or further apart along the Y-axis to change the distance between them.

[0027] A third drive structure is disposed on the sliding seat, and the third drive structure is used to drive the two forks to move closer or further apart to change the distance between the two forks.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0048] As shown in Figures 2-7, this utility model provides a reach truck AGV, including an AGV body 100 and a forklift device mounted on the AGV body 100.

[0049] The forklift device includes a moving frame 210, a first drive assembly, a fork assembly, and a second drive assembly.

[0050] The movable frame 210 is movably mounted on the AGV body 100, enabling it to reciprocate linearly along the X-axis. Specifically, the AGV body 100 has a U-shaped mounting groove 110 extending from top to bottom through the AGV body 100. The movable frame 210 is movably mounted in the mounting groove 110.

[0051] When installing the mobile frame 210, because the mounting slot 110 runs through the entire AGV body 100, the installation height of the mobile frame 210 can be minimized, thereby minimizing the minimum working height and installation height of the fork assembly and the overall height of the AGV. This allows it to be adapted to low warehouses, shelves, or pallets, improving space accessibility. At the same time, the low center of gravity structure enhances the stability of the AGV during movement, especially reducing the risk of tipping over when picking up heavy objects, thus improving the stability of picking up shelves or pallets.

[0052] The bottom of the mounting slot 110 is symmetrically equipped with first guide rails 120 on both sides. The cross-section of the first guide rail 120 is U-shaped. The two sides of the movable frame 210 are respectively provided with first rollers (not shown in the figure) that are adapted to the first guide rail 120.

[0053] During operation, the U-shaped first guide rail 120 engages with the first roller of the movable frame 210, bringing the support point of the movable frame 210 close to the bottom of the AGV body 100, further lowering the center of gravity. At the same time, the U-shaped first guide rail 120 provides lateral restraint, limiting the left and right swaying of the movable frame 210 and ensuring that the load center of gravity remains within the stable support range of the AGV body 100 when forking goods.

[0054] Meanwhile, the cross-section of the first guide rail 120 is U-shaped, forming a "groove-roller" fit with the first roller, which can precisely limit the movement of the moving frame 210 in the X-axis direction, avoid the gap error of traditional sliding guide rails, and ensure that the moving frame 210 moves smoothly in a straight line, especially reducing deflection when the forks 233 are inserted into the shelf or pallet, and improving operational stability.

[0055] In addition, the cooperation between the first roller and the first guide rail 120 can reduce friction, thereby reducing response time.

[0056] The first end of the fork assembly is connected to the moving frame 210, the second end extends along the X-axis, and the fork assembly can reciprocate linearly along the Z-axis to change the height of the fork assembly.

[0057] The first drive assembly is mounted on the AGV body 100 and is connected to the moving frame 210 via a transmission connection. The first drive assembly drives the moving frame 210 to perform reciprocating linear motion along the X-axis and can hold the moving frame 210 at a target position. The second drive assembly is mounted on the moving frame 210 and is connected to the fork assembly via a transmission connection. The second drive assembly drives the fork assembly to perform lifting and lowering motion and can hold the fork assembly at a target position.

[0058] During operation, firstly, the second drive component drives the fork assembly to move to the target position and hold it there; then, the first drive component drives the moving frame 210 forward, causing the fork assembly to insert under the target shelf or target pallet; next, the second drive component drives the fork assembly to rise, causing it to lift the target shelf or target pallet; then, the first drive component drives the moving frame 210 backward, moving the target shelf or target pallet above the AGV body 100; finally, the second drive component drives the fork assembly to descend, placing the target shelf or target pallet on the AGV body 100.

[0059] As shown in Figure 4, in this embodiment, the first drive component includes a chain box 221, a rigid chain 222, and a first drive structure.

[0060] A chain box 221 is fixedly mounted on the AGV body 100, and the chain box 221 has an inlet and outlet. A rigid chain 222 is disposed inside the chain box 221, with one end of the rigid chain 222 extending out of the inlet and outlet and connecting to the moving frame 210. A first drive structure is disposed on the AGV body 100, and the first drive structure is used to drive the rigid chain 222 to extend out of or retract into the chain box 221.

[0061] During operation, the first drive structure drives the rigid chain 222 to extend from the chain box 221. The rigid chain 222 applies a pushing force to the movable frame 210, thereby pushing the movable frame 210 forward, so that the fork assembly inserts under the target shelf or target pallet. The first drive structure drives the rigid chain 222 to retract into the chain box 221. The rigid chain 222 applies a pulling force to the movable frame 210, thereby pulling the movable frame 210 backward.

[0062] Specifically, in this embodiment, the first drive structure includes a sprocket (not shown in the figures) and a first motor 223.

[0063] The sprocket is housed in the chain box 221 and rotatably connected to the chain box 221, and the sprocket meshes with the rigid chain 222. The first motor 223 is fixedly mounted on the AGV body 100, and the power output shaft of the first motor 223 is connected to the power input shaft of the sprocket to drive the sprocket to rotate.

[0064] During operation, the first motor 223 drives the sprocket to rotate, which in turn drives the rigid chain 222 to move, thereby causing the rigid chain 222 to extend into or retract from the chain box 221. Specifically, when the first motor 223 drives the sprocket to rotate in the forward direction, the sprocket drives the rigid chain 222 to extend out of the chain box 221; when the first motor 223 drives the sprocket to rotate in the reverse direction, the sprocket drives the rigid chain 222 to retract into the chain box 221.

[0065] In this embodiment, the first drive component, the rigid chain 222, can be housed within the rigid chain 222, making the overall structural layout more compact. Compared with flexible chains or belts, the rigid chain 222 has stronger resistance to deformation and almost no elastic deformation when transmitting thrust and tension, which can ensure the accuracy and reliability of the movement of the moving frame 210. At the same time, by controlling the extension length of the rigid chain 222, the stroke and positioning can be precisely controlled.

[0066] As shown in Figures 1, 4, 5, and 7, in this embodiment, the second drive assembly includes a lifting frame 241 and a second drive structure.

[0067] The lifting frame 241 is movably connected to the movable frame 210, enabling the lifting frame 241 to move vertically along the Z-axis. Specifically, the movable frame 210 has symmetrically arranged second guide rails A211 on both sides, and the lifting frame 241 has symmetrically arranged second guide rails B201 on both sides, which cooperate with the second guide rails A211. During operation, the cooperation of the second guide rails A211 and B201 effectively suppresses the left-right swaying or front-back tilting of the lifting frame 241 during the lifting process, thereby improving the reliability of the operation.

[0068] Preferably, the second guide rail A211 and the second guide rail B201 are I-shaped to enhance their strength and thus improve their service life. The second guide rail A211 and the second guide rail B201 are staggered and interlocked. A second roller A212 is rotatably mounted on the top of the second guide rail A211, and the outer diameter of the second roller A212 matches the groove of the second guide rail B201. A second roller B is rotatably mounted on the bottom of the second guide rail B201, and the outer diameter of the second roller B matches the groove of the second roller A212.

[0069] The second roller A212 and the second guide rail B201, as well as the second guide rail A211 and the second roller B, form a "groove-roller" fit, which can precisely limit the movement of the lifting frame 241 in the Z-axis direction, thereby ensuring that the lifting frame 241 moves smoothly along a straight line and improving operational stability. At the same time, the fit between the second roller A212 and the second guide rail B201, and between the second guide rail A211 and the second roller B, can also reduce friction, thereby reducing response time.

[0070] The lifting frame 241 is connected to the fork assembly so that the lifting frame 241 can move together with the fork assembly. Specifically, the lifting frame 241 and the fork assembly are connected by a flexible connecting belt 243. Specifically, the first end of the connecting belt 243 is fixedly connected to the lifting frame 241, and the second end is fixedly connected to the fork assembly. During operation, the connecting belt 243 is elastic, which can buffer the inertial impact force when the lifting frame 241 is raised or lowered, thereby reducing the instantaneous stress on components such as the second guide rail A211, the second guide rail B201, and the second drive structure, and thus extending the equipment's lifespan.

[0071] Preferably, the lifting frame 241 is provided with a guide wheel (not shown in the figure), and the first end of the connecting belt 243 is fixedly connected to the lifting frame 241, and the second end is fixedly connected to the fork assembly after passing around the guide wheel, so as to improve the reliability of the whole device.

[0072] The second drive structure is mounted on the movable frame 210 and is used to drive the lifting frame 241 to perform lifting and lowering movements.

[0073] During operation, when the second drive structure drives the lifting frame 241 to rise, the height of the lifting frame 241 increases, and the lifting frame 241 carries the fork assembly to rise; when the second drive structure drives the lifting frame 241 to fall, the height of the lifting frame 241 decreases, thereby carrying the fork assembly to fall.

[0074] Specifically, in this embodiment, the second driving structure includes a second telescopic device 242, which is mounted on the movable frame 210. The power output end of the second telescopic device 242 is connected to the lifting frame 241 to drive the lifting frame 241 to perform lifting movements. Specifically, the second telescopic device 242 is one of an electric push rod, an electro-hydraulic push rod, a pneumatic cylinder, or a hydraulic cylinder.

[0075] During operation, the second telescopic device 242 extends, thereby driving the lifting frame 241 to rise, and in turn driving the fork assembly to rise; the second telescopic device 242 retracts, thereby driving the lifting frame 241 to fall, and in turn driving the fork assembly to fall.

[0076] As shown in Figures 2, 3, 4, 6, and 7, in this embodiment, the fork assembly includes a sliding seat 231, forks 233, and a third drive structure.

[0077] The sliding seat 231 is movably mounted on the movable frame 210 so that the sliding seat 231 can move up and down along the Z-axis. Specifically, the movable seat is mounted on the lifting frame 241. Third rollers 232 are provided on both sides of the sliding seat 231. The outer diameter of the third rollers 232 is adapted to the groove of the second guide rail B201 to limit the back-and-forth and left-and-right swing of the sliding seat 231.

[0078] Two forks 233 are provided, spaced apart along the Y-axis. The first end of each fork 233 is connected to the sliding seat 231, and the second end extends along the X-axis. The two forks 233 can move closer or further apart along the Y-axis, so that the distance between the two forks 233 can be changed.

[0079] During operation, the spacing between the two forks 233 can be adjusted to accommodate different sizes of shelves or pallets, ensuring stable support for different shelves or pallets and preventing goods from tilting or slipping. At the same time, this adjustability improves the versatility of the AGV, reduces the need for different models of equipment, and thus achieves the goal of reducing costs.

[0080] Specifically, a fourth roller A234 is rotatably mounted on the first end of the fork 233. The axis of the fourth roller A234 is parallel to the X-axis, and its circumferential wall abuts against the top and bottom side walls of the sliding seat 231. A fourth roller B235 is also rotatably mounted on the first end of the fork 233. The axis of the fourth roller B235 is parallel to the Z-axis, and its circumferential wall abuts against the front and rear side walls of the sliding seat 231. During operation, the cooperation of the fourth rollers A234 and B235 with the corresponding side walls of the sliding seat 231 achieves the purpose of limiting the vertical and horizontal movement and the forward and backward movement of the sliding seat 231, while also reducing friction.

[0081] The third drive structure is mounted on the sliding seat 231. The third drive structure is used to drive the two forks 233 to move closer or further apart, so as to change the distance between the two forks 233.

[0082] Specifically, the third drive structure includes a third telescopic device 236, which is mounted on the sliding seat 231. Two third telescopic devices 236 are provided, and their power output ends are respectively connected to two forks 233. Specifically, the first end of the third telescopic device 236 is fixedly connected to the sliding seat 231, and the second end is fixedly connected to the forks 233. Preferably, the first end of the third telescopic device 236 is fixedly connected to one side of the sliding seat 231, and the other end is fixedly connected to the fork 233 located on the other side of the sliding seat 231, to achieve a more compact overall structure for the fork assembly.

[0083] The third telescopic device 236 is one of an electric push rod, an electro-hydraulic push rod, a pneumatic cylinder, or a hydraulic cylinder.

[0084] Finally, it should be noted that in all embodiments of this utility model, the X-axis direction refers to the length direction of the AGV body 100, the Y-axis direction refers to the width direction of the AGV body 100, and the Z-axis direction refers to the longitudinal direction.
