[0030] The locking component of this invention is mainly used in intelligent transfer vehicles to enable the intelligent transfer vehicle to connect with the rotary disconnector circuit breaker, thereby improving the stability of the transfer of large or heavy components such as the handcart, insulation board, and current transformer of the rotary disconnector circuit breaker.

[0031] Please refer to Figures 1 to 4 According to one embodiment of the present invention, a locking assembly 700 is provided, comprising a mounting base 710, an actuator 720, and a locking hook 730. The mounting base 710 is fixed on the frame 100 of the intelligent transfer vehicle. The actuator 720 is mounted on the mounting base 710 and connected to the locking hook 730. The end of the actuator 720 connected to the locking hook 730 is movable along the length of the mounting base 710 to drive the locking hook 730 to swing relative to the mounting base 710. Therefore, when an external driving signal is received, the locking hook 730, driven by the actuator 720, swings within a certain angle, thereby achieving locking and unlocking between the locking hook 730 and the electrical switchgear of the longitudinal rotary disconnect circuit breaker to be connected.

[0032] Specifically, the locking hook body 730 of this utility model includes a body 731 and a protrusion 732 disposed at the bottom of the body 731. The end of the body 731 near the actuator 720 is rotatably mounted on the mounting base 710, and the end of the body 731 away from the actuator 720 forms a hook portion 733. The hook portion 733 is located outside the frame 100 of the intelligent transfer vehicle, so the intelligent transfer vehicle and the electrical switch cabinet are locked by hooking the hook portion 733 against the electrical switch cabinet. The protrusion 732 has a sliding groove 734 that is inclined relative to the upper surface of the body 731. The actuator 720 is provided with a pusher 740 that slides in the sliding groove 734 to push the body 731 to swing relative to the mounting base 710.

[0033] Preferably, in this embodiment, the actuator 720 is an actuating cylinder. The cylinder barrel of the actuating cylinder is fixed on the mounting base 710, and its movable rod 721 is connected to the push block 740. Thus, the reciprocating motion of the push block 740 is achieved through the extension and retraction of the movable rod 721, thereby pushing the lock hook body 730 to swing. In this embodiment, the lock hook body 730 swings up and down relative to the mounting base 710, and the hook portion 733 of the lock hook body 730 is bent upward into a hook shape.

[0034] The mounting base 710 has a bearing 711 at one end and a rotating base 712 at the other end. The bearing 711 is used to mount the actuating cylinder, and the rotating base 712 is used to mount the locking hook body 730. The bearing 711 has a pin hole 713, through which a pin is inserted to fix the cylinder barrel of the actuating cylinder within the mounting base 710. This facilitates installation and removal, allowing for the replacement of actuating cylinders with different strokes according to different usage needs. The locking hook body 730 is pivotally mounted within the rotating base 712. The rotating base 712 has a first pivot hole 714, and the end of the locking hook body 730 that connects to the mounting base 710 has a second pivot hole 735. A first pivot passes through the first pivot hole 714 and the second pivot hole 735 to connect the locking hook body 730 to the rotating base 712, allowing the locking hook body 730 to rotate relative to the rotating base 712.

[0035] This invention uses an actuating cylinder to push a push block 740 to drive the locking hook body 730 to swing up and down. One end of the push block 740 is connected to the end of the movable rod 721 of the actuating cylinder, and the other end is provided with a movable groove 741. The protrusion 732 of the locking hook body 730 is inserted into the movable groove 741. At the same time, a third pivot hole 742 is opened on both sides of the groove wall of the push block 740 located in the movable groove 741, and a rotating shaft 744 is provided in the third pivot hole 742 on both sides of the movable groove 741, which is inserted into the sliding groove 734 of the protrusion 732. Therefore, in this embodiment, since the sliding groove 734 of the protrusion 732 is inclined relative to the upper surface of the body 731, when the movable rod 721 of the actuating cylinder extends and retracts, it will drive the push block 740 to reciprocate synchronously. The rotating shaft 744 slides in the sliding groove 734, causing the locking hook body 730 to swing up and down relative to the rotating seat 712 within a certain range.

[0036] In a specific embodiment, when the movable rod 721 of the brake cylinder retracts into its cylinder, the locking hook body 730 is in a horizontal state and is not hooked into the corresponding lock hole on the electrical switchgear; when the movable rod 721 of the actuating cylinder extends out of its cylinder, it pushes the push block 740 to lift the locking hook body 730 upward, thereby hooking the hook 733 into the lock hole provided on the electrical switchgear, so as to realize the temporary mutual fixation between the intelligent transport vehicle and the electrical switchgear, and ensure the stability and safety of subsequent transfer operations.

[0037] More preferably, the mounting base 710 is provided with a detection switch 750 for detecting the position of the push block 740. In this embodiment, two detection switches 750 are provided, corresponding to the beginning and end of the movement displacement of the push block 740 on the mounting base 710, respectively. Preferably, the detection switch 750 in this embodiment is a photoelectric switch. The push block 740 is provided with a baffle 743 that moves with the push block 740 and can be inserted into the photoelectric switch. When the baffle 743 is inserted into the photoelectric switch, the light beam between the transmitter and receiver of the photoelectric switch is blocked, thereby detecting that the push block 740 has moved to the beginning or end of its movement displacement. When the baffle 743 moves with the push block 740 to the photoelectric switch at the beginning, the movable rod 721 retracts into the cylinder of the actuating cylinder, and the locking hook 730 is not connected to the lock hole of the electrical switch cabinet. However, when the baffle 743 moves with the push block 740 to the photoelectric switch at the end, the movable rod 721 extends out of the cylinder of the actuating cylinder to push the push block 740, driving the locking hook 730 to swing upwards. This causes the hook 733 to engage with the lock hole of the electrical switch cabinet, completing the locking of the intelligent transport vehicle and the electrical switch cabinet. This embodiment utilizes a photoelectric switch to detect the position movement of the push block 740 to effectively control the swing of the locking hook 730. It offers high detection accuracy and fast response, improving the connection efficiency and stability between the intelligent transport vehicle and the electrical switch cabinet.

[0038] Therefore, when transferring or maintaining handcarts or transformers via intelligent transfer carts and electrical switchgear, the locking component 700 can be used to lock the intelligent transfer cart and electrical switchgear together. This prevents the intelligent transfer cart from shifting relative to the electrical switchgear due to the reaction force of the gripping action during the transfer or maintenance process, which could lead to dangerous situations, such as the transferred device falling to the ground due to a loose grip, resulting in damage. Thus, the locking component 700 of this invention improves the stability of the gripping operation during transfer or maintenance, reducing the likelihood of devices falling due to displacement of the intelligent transfer cart relative to the electrical switchgear.

[0039] Furthermore, this utility model also discloses an intelligent transfer vehicle, which includes a frame 100, a lifting component 200, a track component 300, a push-pull component 400, a gripping component 500, and an electrical control box 600. The lifting component 200 is mounted on the frame 100 to enable the gripping component 500 to move up and down, while the push-pull component 400 mounted on the frame 100 is used to enable the gripping component 500 to move horizontally. Specifically, the track assembly 300 is mounted on the lifting assembly 200 and is driven by the lifting assembly 200 to move up and down. The push-pull assembly 400 is mounted on the track assembly 300 and moves on the track assembly 300. The gripping assembly 500 is mounted on the push-pull assembly 400. The gripping assembly 500 is used to grip devices such as handcarts or current transformers. Therefore, the devices to be transferred (such as handcarts or current transformers) can be lifted up or pushed and pulled back and forth in the vertical and horizontal directions, thereby realizing the transfer and maintenance of handcarts or current transformers. The operation is convenient, time-saving, labor-saving, accurate in positioning, and quick in adjustment.

[0040] Furthermore, the intelligent transfer vehicle of this invention also includes a locking component 700 disposed at the end of the track assembly 300 extending outside the frame 100. This locking component 700 is the same as described above. The track assembly 300 includes a track mounting base 310 disposed on the frame 100 and a track 320 disposed on the track mounting base 310. The track 320 has an extended end extending outside the frame 100, and the locking component 700 is mounted on the extended end. Therefore, the intelligent transfer vehicle of this invention utilizes the locking component 700 extending outside the frame 100 to connect with the electrical switchgear, thereby achieving a quick temporary connection between the intelligent transfer vehicle and the electrical switchgear.

[0041] More preferably, the track 320 has a baffle 321 in front of the rotating seat 712 of the locking assembly 700. The baffle 321 has a window 322, through which the locking hook 730 of the locking assembly 700 can extend for connection with the lock hole of the electrical switchgear. Because the locking hook 730 extends to the outside of the baffle 321, when the locking hook 730 is connected to the lock hole of the electrical switchgear, the baffle 321 ensures a secure fit between the intelligent transfer vehicle and the electrical switchgear, facilitating the entry of the hook 733 of the locking hook 730 into the lock hole of the electrical switchgear to achieve the locking action.

[0042] In summary, in the intelligent transfer vehicle equipped with the locking component 700 mentioned above, the locking component 700 locks the intelligent transfer vehicle to the electrical switch cabinet, thereby ensuring the mutual fixation between the frame 100 and the electrical switch cabinet. Then, the gripping component 500 is used to transfer or maintain devices such as handcarts or current transformers. The system has high stability and high work efficiency.
