The actuating member 720 is connected to the lock hook body 730, and the end of the actuating member 720 connected to the lock hook body 730 can move along the length direction of the mounting seat 710 to drive the lock hook body 730 to swing relative to the mounting seat 710. Therefore, when an external driving signal is received, the lock hook body 730 driven by the actuating member 720 swings within a certain angle, thereby realizing the locking and unlocking between the lock hook body 730 and the electrical switch cabinet of the longitudinal rotation type disconnecting circuit breaker to be connected.

[0032] Specifically, the lock hook body 730 of the present invention includes a body 731 and a protrusion 732 disposed at the bottom of the body 731. The end of the body 731 close to the actuator 720 is rotatably mounted on the mounting seat 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 transport vehicle, so the intelligent transport vehicle and the electrical switch cabinet are locked by hanging on the electrical switch cabinet through the hook portion 733. The protrusion 732 is provided with a slide groove 734 inclined relative to the upper surface of the body 731, and the actuator 720 is provided with a push block 740 that slides in the slide groove 734 to push the body 731 to swing relative to the mounting seat 710.

[0033] Preferably, the actuating member 720 in this embodiment is an actuating cylinder, the cylinder barrel of which is fixed on the mounting seat 710, and the movable rod 721 thereof is connected to the push block 740, so that the reciprocating motion of the push block 740 is realized by the telescopic motion of the movable rod 721, so as to push the lock hook body 730 to swing. The lock hook body 730 of this embodiment swings up and down relative to the mounting seat 710, and the hook portion 733 of the lock hook body 730 is bent upward to form a hook.

[0034] The mounting seat 710 is provided with an axle seat 711 at one end and a rotating seat 712 at the other end, wherein the axle seat 711 is used to mount the actuating cylinder, and the rotating seat 712 is used to mount the lock hook body 730. The axle seat 711 is provided with a pin hole 713, and a pin for fixing the cylinder barrel of the actuating cylinder in the mounting seat 710 is inserted into the pin hole 713, which is convenient for installation and removal, and can replace the actuating cylinder with different strokes according to different usage needs. The lock hook body 730 is pivotally arranged in the rotating seat 712, and a first pivot hole 714 is provided in the rotating seat 712. The end of the body 731 of the lock hook body 730 for connecting with the mounting seat 710 is provided with a second pivot hole 735, and a first pivot shaft passing through the second pivot hole 735 is inserted into the first pivot hole 714 to connect the lock hook body 730 with the rotating seat 712, and the lock hook body 730 can rotate relative to the rotating seat 712.

[0035] The present invention drives the lock hook body 730 to swing up and down by pushing the push block 740 by the actuating cylinder. 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 lock hook body 730 is inserted into the movable groove 741. At the same time, the push block 740 is provided with a third pivot hole 742 on both sides of the groove wall of the movable groove 741, and a rotating shaft 744 inserted into the sliding groove 734 of the protrusion 732 is provided in the third pivot hole 742 on both sides of the movable groove 741. 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 is extended and retracted, it will drive the push block 740 to reciprocate synchronously, and the rotating shaft 744 slides in the sliding groove 734 so that the lock hook body 730 swings up and down within a certain range relative to the rotating seat 712.

[0036] In a specific embodiment, when the movable rod 721 of the brake cylinder is retracted in its cylinder barrel, the lock hook body 730 is in a horizontal state and is not hooked in the corresponding lock hole on the electrical switch cabinet; when the movable rod 721 of the actuating cylinder extends out of its cylinder barrel, the push block 740 is pushed to lift the lock hook body 730 upward, so that the hook portion 733 is hooked in the lock hole provided in the electrical switch cabinet, so as to realize the temporary fixation of the intelligent operation vehicle and the electrical switch cabinet to each other, and ensure the stability and safety of subsequent transportation operations.

[0037] Further preferably, the mounting seat 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, and the two detection switches 750 correspond to the starting end and the end of the displacement of the push block 740 on the mounting seat 710, respectively. The detection switch 750 of this embodiment is preferably a photoelectric switch, and 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 the receiver of the photoelectric switch is blocked, thereby detecting that the push block 740 has moved to the starting end or the end of its displacement. That is, when the baffle 743 moves with the push block 740 to the photoelectric switch at the beginning, the movable rod 721 shrinks in the cylinder of the actuating cylinder, and the lock hook body 730 is not connected to the lock hole of the electrical switch cabinet; and 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 to drive the lock hook body 730 to swing upward, so that the hook part 733 is hung in the lock hole of the electrical switch cabinet, completing the locking of the intelligent transport vehicle and the electrical switch cabinet. This embodiment uses a photoelectric switch to detect the position movement of the push block 740 to effectively control the swing of the lock hook body 730, with high detection accuracy and fast response speed, which can improve the connection efficiency between the intelligent transport vehicle and the electrical switch cabinet and improve the stability of the connection between the two.

[0038] Therefore, when the handcart or mutual inductor is transported or maintained by the intelligent transport vehicle and the electrical switch cabinet, the intelligent transport vehicle and the electrical switch cabinet can be locked by the locking assembly 700 first, so as to avoid the intelligent transport vehicle being displaced relative to the electrical switch cabinet due to the reaction force of the grabbing during the transport or maintenance process, thereby preventing dangerous situations from occurring during the transport or maintenance process, such as the transport grabbing being loose and causing the transported device to fall to the ground, resulting in damage to the device. Therefore, the locking assembly 700 of the present invention can improve the stability of the grabbing operation during the transport or maintenance process, and reduce the situation where the device falls due to the displacement of the intelligent transport vehicle relative to the electrical switch cabinet.

[0039] Furthermore, the present invention also discloses an intelligent transfer vehicle, which includes a frame 100, a lifting assembly 200, a track assembly 300, a push-pull assembly 400, a grabbing assembly 500, and an electrical control box 600, wherein the lifting assembly 200 is arranged on the frame 100 to realize the up and down movement of the grabbing assembly 500, and the push-pull assembly 400 arranged on the frame 100 is used to use the grabbing assembly 500 to move in the horizontal direction. Specifically, the track assembly 300 is arranged on the lifting assembly 200 and is driven to rise and fall by the lifting assembly 200, the push-pull assembly 400 is arranged on the track assembly 300, and the push-pull assembly 400 moves on the track assembly 300, and the grabbing assembly 500 is installed on the push-pull assembly 400, and the grabbing assembly 500 is used to grab devices such as trolleys or mutual inductors, so the devices to be transported (such as trolleys or mutual inductors, etc.) can be lifted or pushed and pulled back and forth in the vertical and horizontal directions, thereby realizing the transportation and maintenance of trolleys or mutual inductors, which is convenient to operate, saves time and effort, has accurate positioning and rapid adjustment.

[0040] In addition, the intelligent transport vehicle of the present invention further includes a locking assembly 700 arranged at the end of the track assembly 300 extending outside the frame 100, and the locking assembly 700 is the locking assembly 700 described above, and the track assembly 300 includes a track mounting seat 310 arranged on the frame 100 and a track 320 arranged on the track mounting seat 310, and the track 320 has an extended end extending outside the frame 100, and the locking assembly 700 is installed on the extended end. Therefore, the intelligent transport vehicle of the present invention utilizes the locking assembly 700 extending outside the frame 100 to connect with the electrical switch cabinet, so as to realize a quick temporary connection between the intelligent transport vehicle and the electrical switch cabinet.

[0041] Further preferably, the track 320 is provided with a baffle 321 in front of the rotating seat 712 of the locking assembly 700, and a window 322 is opened on the baffle 321, and the lock hook body 730 of the locking assembly 700 can extend from the window 322 to be connected with the lock hole of the electrical switch cabinet. Since the lock hook body 730 extends to the outside of the baffle 321, when the lock hook body 730 is connected with the lock hole of the electrical switch cabinet, the baffle 321 can realize the firm fit between the intelligent transport vehicle and the electrical switch cabinet, and facilitate the hook part 733 of the lock hook body 730 to enter the lock hole of the electrical switch cabinet to realize the locking action.

[0042] In summary, in the intelligent transfer vehicle equipped with the locking assembly 700 mentioned above, the intelligent transfer vehicle and the electrical switch cabinet are locked by the locking assembly 700, thereby ensuring the mutual fixation between the frame 100 and the electrical switch cabinet, and then the grasping assembly 500 is used to transport or maintain devices such as the trolley or the transformer, with high stability and high work efficiency.
