[0040] Specifically, the chassis 1 is an omnidirectional chassis. For example, the chassis of an AGV forklift can be adopted. Here, the AGV forklift is an unmanned forklift specifically used for cargo handling and stacking operations. The chassis 1 in this embodiment can achieve various functions such as 360° in-situ rotation, sideward translation, right-angle turning, and diagonal operation. In this embodiment, for example, the movement of the chassis 1 along the X-axis can drive the adjustment mechanism on the gantry assembly 2, so as to realize the linear movement of the rotor 100 along the X-axis. In this embodiment, the X-axis represents Figure 1 the front-back direction (i.e., the second direction) in Figure 1 and the left-right direction (i.e., the third direction) in Figure 1 and the up-down direction (i.e., the first direction) in

[0041] To realize the control of the movement of the chassis 1, preferably, the chassis 1 includes a remote control device, and through the remote control device, the corresponding movement functions of the chassis 1 can be controlled.

[0042] Furthermore, the gantry assembly 2 is arranged on the chassis 1 and extends along the Z-axis direction. The adjustment mechanism is arranged on the gantry assembly 2, and can be fixed on the front side of the gantry assembly 2 through fasteners such as bolts. Through the cooperation of the adjustment mechanism and the gantry assembly 2, the disassembly and assembly of the rotor 100 of, for example, a hundred-ton level can be realized, greatly reducing the labor intensity of the operator.

[0043] Furthermore, the chassis 1 here includes a recess 4, and the gantry assembly 2 is arranged in the space formed by the recess 4, which is convenient for the installation of the adjustment mechanism on the gantry assembly 2 to save installation space, and at the same time convenient for the disassembly and assembly of the rotor 100.

[0044] The adjustment mechanism is slidably arranged on the gantry assembly 2, and the adjustment mechanism can move up and down along the Z-axis direction relative to the gantry assembly 2, so as to drive the rotor 100 to realize the up and down movement along the Z-axis direction.

[0045] Furthermore, the adjustment mechanism includes a slewing drive seat 11, a slewing main beam 12, and a guide rail 13. Here, the slewing drive seat 11 is arranged on the gantry assembly 2, and the slewing main beam 12 and the guide rail 13 both extend along the Y-axis direction. The rotor 100 is connected to the slewing main beam 12; wherein, the slewing drive seat 11 is connected to the gantry assembly 2 through a slewing support member, for example. A rotary shaft extending along the Z-axis direction is arranged on the slewing drive seat 11, and the first end of the slewing main beam 12 is sleeved on the rotary shaft, so that the slewing main beam 12 can rotate relative to the slewing drive seat 11 around the axis of the rotary shaft (that is, the Z-axis direction).

[0046] Further, a first driving device and a first transmission device are connected to each other on the slewing drive base 11. The output end of the first transmission device is connected to the slewing main beam 12. Through the first driving device and the first transmission device, the slewing main beam 12 can be rotated, and further drive the rotor 100 to rotate along the Z-axis direction.

[0047] Wherein, in this embodiment, the first driving device may be a first servo motor 21, and the first transmission device is a first reducer assembly. Here, the first reducer assembly may be a first reducer 22 and a second reducer 23 connected to each other. The input end of the first reducer 22 is connected to the first servo motor 21, and the output end of the second reducer 23 is connected to the slewing main beam 12 through, for example, a flange.

[0048] In this way, the first servo motor 21 drives the first reducer 22, and the first reducer 22 drives the second reducer 23, so as to drive the slewing main beam 12 to rotate around the Z-axis direction, and further drive the rotor 100 to be able to rotate around the Z-axis direction through the guide rail 13.

[0049] Further, a support frame 14 is arranged on the first side of the guide rail 13. The rotor 100 is arranged on the support frame 14. The rotor 100 can move in multiple directions and / or rotate around multiple directions. A counterweight 3 is arranged on the second side of the guide rail 13. Here, the counterweight 3 is used to balance the weight of the rotor 100 to avoid the imbalance of the gantry assembly 2.

[0050] Further, a first hinge seat 131 is arranged in the middle of the guide rail 13. The first end of the slewing main beam 12 is rotatably connected to the guide rail 13 through the first hinge seat 131. The guide rail 13 is rotatably connected to the slewing main beam 12 to rotate around the X-axis direction.

[0052] Specifically, a second hinge seat 121 is further arranged at the second end of the slewing main beam 12. One end of the main body part 151 of the telescopic cylinder 15 is rotatably connected to the second end of the slewing main beam 12 through the second hinge seat 121.

[0053] Further, a third hinge seat 132 is also provided on the second side of the guide rail 13, and the other end of the main body portion 151 of the telescopic cylinder 15 is rotatably connected to the second side of the guide rail 13 through the third hinge seat 132.

[0054] In this embodiment, the rotation of the rotor 100 is realized based on the lever principle through the cooperation between the telescopic cylinder 15 and the first hinge seat 131. Specifically, when the telescopic portion 152 of the telescopic cylinder 15 extends or retracts the telescopic rod along the Z-axis direction, a force is applied to or removed from the second end of the guide rail 12. According to the lever principle, a fulcrum is formed at the position of the first hinge seat 131, and the rotation of the guide rail 13 around the fulcrum enables the rotor 100 to rotate upward or downward around the X-axis direction.

[0055] Further, the support frame 14 includes a bottom plate 141, and a vertical plate 142 is provided on each side of the bottom plate 141. The bottom plate 141 and the vertical plates 142 are both arranged along the extension direction of the guide rail 13 (i.e., the Y-axis direction). Among them, the bottom plate 141 is located below the guide rail 13, and the two vertical plates 142 are respectively located on both sides of the guide rail 13. A connecting member 143 is provided below the bottom plate 141, and a rotor drive shaft 110 is provided on the connecting member 143. The rotor drive shaft 110 can rotate on the connecting member 143, and the end of the rotor drive shaft 110 is used to connect to the rotor 100.

[0056] Further, the rotor 100 is connected to the rotor drive shaft 110 through a connecting flange 38, and the rotor drive shaft 110 enables the rotor 100 to rotate around the Y-axis.

[0058] Specifically, the second reducer assembly includes a third reducer 32 and a fourth reducer 33 that are connected to each other. The second servo motor 31 is connected to the input end of the third reducer 32, and the output end of the fourth reducer 33 is connected to the gear-rack assembly.

[0059] Furthermore, the gear-rack assembly includes a gear 34 and a rack 35. Among them, the gear 34 is connected to the output end of the fourth speed reducer 33, and the rack 35 is arranged on the guide rail 13 and meshes with the gear 34 to drive the movement of the support frame 14 in the Y-axis direction through the rotation of the gear 34. The pulley 36 here is used to assist the movement of the support frame 14. Specifically, the rotation of the gear 34 on the rack 35 can drive the support frame 14 to move relative to the guide rail 13 in the Y-axis direction. At the same time, the pulley 36 drives the support frame 14 to move on the guide rail 13 to reduce friction, and finally drives the rotor 100 to move in the Y-axis direction.

[0060] In addition, the drive device further includes a first handwheel 37, and the first handwheel 37 is connected to the second speed reducer assembly, especially to the input end of the third speed reducer 32. In this way, by operating the first handwheel 37, the operation of the second speed reducer assembly can also be driven.

[0061] In this embodiment, the rotation of the second servo motor 31 is used to drive the third speed reducer 32, the third speed reducer 32 drives the fourth speed reducer 33, the fourth speed reducer 33 drives the gear 34 to rotate on the rack 35, and the pulley 36 drives the support frame 14 to reciprocate along the extension direction of the guide rail 13. Finally, the linear reciprocating motion of the rotor 100 in the Y-axis direction is realized through the movement of the support frame 14 on the heavy-duty guide rail 13. In addition, in this embodiment, while realizing the electric adjustment of the linear motion, the operator can also drive the rotor 100 to realize the linear motion in the Y-axis direction by shaking the first handwheel 37.

[0062] In this embodiment, a third drive device and a third transmission device are further arranged on the support frame 14.

[0065] In addition, while the electric adjustment is achieved through the third driving device and the third transmission device, the operator can also drive the rotor 100 to rotate around the Y-axis direction by shaking the second hand wheel 44.

[0066] In this embodiment, whether controlling the rotor 100 to move linearly along the Y-axis direction or to rotate around the Y-axis direction, a reducer assembly formed by two reducers can achieve two-stage reduction in speed to increase the reduction ratio, thereby achieving precise control of the movement or rotation of the rotor 100.

[0067] Furthermore, the third reducer 32 and the fourth reducer 33 or the fifth reducer 42 and the sixth reducer 43 are arranged in an L shape, which can minimize the space occupied by the reducer assembly.

[0068] In addition, the third reducer 32 and / or the fifth reducer 42 are both connected to corresponding hand wheels, and the hand wheels can realize electric adjustment and corresponding control manually at the same time.
