[0026] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, rather than any limitation on the utility model and its application or use.

[0027] Embodiment one

[0028] The embodiment provides a RGV anti-falling structure, which comprises a blocking pin 1 for limiting the movement of RGV out of the inside of a guide rail 9, a first wedge 3 for pushing the blocking pin 1 out of the inside of the guide rail 9 and a reset spring 2 arranged on the blocking pin 1, the wheels of the RGV 10 are located in the inside of the guide rail 9, one end of the blocking pin 1 is arranged in the inside of the guide rail 9 from the side surface of the guide rail 9, and the first wedge 3 is installed on a lifting frame 11.

[0029] The lifting frame 11 moves up and down through an elevator 12 and is used for receiving the RGV, the first wedge 3 is installed on the lifting frame 11, when the lifting frame 11 is located at the position for receiving the RGV 10, the first wedge 3 on the lifting frame 11 pushes the blocking pin 1 out of the inside of the guide rail 9.

[0030] The first wedge 3 moves up and down along with the lifting frame 11, in the process of moving the lifting frame 11 to the position, the first wedge 3 pushes the blocking pin 1 to move and gradually separates from the inside of the guide rail 9, when the lifting frame 11 moves to the position, the blocking pin 1 completely separates from the inside of the guide rail 9 and no longer limits the wheels of the RGV 10, and the RGV 10 enters the lifting frame 11 and is conveyed to the designated position.

[0031] Before the lifting frame 11 is in place, the RGV10, which has moved to the end of the guide rail 9, continues to move forward. At this time, the first wedge 3 on the lifting frame 11 has not yet pushed the stop pin 1. The stop pin 1 is still located inside the guide rail 9, which restricts the wheels on the RGV, thereby preventing the RGV from rushing out of the travel guide rail 9 and falling due to misoperation or sensor failure.

[0032] Example 2

[0033] This embodiment provides an RGV anti-fall structure based on Embodiment 1, with the following differences:

[0034] like Figure 1 , Figure 2 , Figure 3 As shown, the wheels on both sides of the RGV10 are respectively mounted on two guide rails 9. A stop pin 1 is provided on the outer side of each guide rail 9. The two stop pins 1 are symmetrically arranged around the central axis of the RGV10 to control the movement of the wheels on both sides of the RGV10 on the guide rails 9, so as to prevent the RGV10 from falling off the guide rails 9 and being damaged before the lifting frame 11 is in place.

[0035] The end of the stop pin 1 away from the side surface of the guide rail 9 is mounted on the base 7. The base 7 includes a base plate and side plates. One end of the base plate is mounted on the bottom of the guide rail 9 by a base bolt 8, and two side plates are arranged at intervals on the other end. A pressure plate 6 is provided on the top of the side plates. The pressure plate 6, the base plate, and the side plates form a compartment. One end of the stop pin 1 passes through the side plate and is located in the compartment, with a fixing nut 5 at the end. A second wedge 4 is provided in the compartment. The second wedge 4 is arranged parallel to the side plate and is installed in a groove in the compartment. It is guided to move by the groove. When the second wedge is pushed by the first wedge, the stop pin and the second wedge are pushed together.

[0036] Both the first wedge 3 and the second wedge 4 have a V-shaped structure with trapezoidal cross-sections at both ends and a wedge angle of 35°. The first wedge 3 and the second wedge 4 engage head-to-tail contact to push each other. The first wedge 3 is mounted on the side rod of the lifting frame 11, which is mounted on the elevator 12. The elevator 12 controls the up-and-down movement of the lifting frame 11. One end of the second wedge 4 extends outward from the compartment. As the lifting frame 11 moves towards the destination point, the outward-extending end of the second wedge 4 contacts the first wedge 3 on the lifting frame 11 and pushes the second wedge 4 away from the guide rail 9. After the lifting frame 11 reaches the destination point, the stop pin 1 disengages from the guide rail 9 and does not obstruct the movement of the RGV10 on the guide rail 9.

[0037] like Figure 2As shown, the blocking pin 1 is provided with a convex ring, one side of the convex ring is in contact with the side edge of the guide rail 9, and the other side is in contact with one end of the reset spring 2 on the blocking pin 1, and the other end of the reset spring 2 is against the side plate close to the guide rail 9. When the blocking pin 1 is pushed by the first wedge block 3 to move away from the end of the guide rail 9, and the first wedge block 3 moves away with the lifting frame 11, the rebounding force of the reset spring 2 acts on the convex ring, driving the blocking pin 1 to move towards the guide rail 9, and the end of the blocking pin 1 extends into the inside of the guide rail 9 for limiting the movement of the RGV.

[0038] As shown in Figure 2 , Figure 4 , Figure 5 As shown, the lifting frame 11 is provided with a first wedge block 3 at both ends, which acts with the blocking pin 1 on the guide rail 9 of the RGV 10 during movement. The movement of the left blocking pin 1 and the first wedge block 3 on the left side of Figure 4 , Figure 5 will be described below. Specifically, the lifting frame 11 is controlled to move downward by the elevator 12, and the first wedge block 3 on the lifting frame 11 moves downward and contacts the second wedge block 4 arranged in the compartment. Since one end of the second wedge block 4 extends from the compartment, when the first wedge block 3 contacts the second wedge block 4, the first wedge block 3 will not contact the blocking pin 1 on the second wedge block 4, and the second wedge block 4 will not contact the lifting frame 11. As the lifting frame 11 moves downward, the first wedge block 3 continuously pushes the second wedge block 4 to move left, and at this time, the spring on the blocking pin 1 is compressed by the side plate and the convex ring. When the first wedge block 3 contacts the rightmost point of the second wedge block 4 at the leftmost point of the first wedge block 3, i.e., the convex points of the two wedge blocks contact each other, the lifting frame 11 is in place, the blocking pin 1 is away from the inside of the guide rail 9, and the end of the blocking pin 1 no longer blocks the wheels of the RGV 10 on the guide rail 9, so the RGV 10 can freely enter the in-place lifting frame 11 from the guide rail 9. After the RGV 10 enters the lifting frame 11, the lifting frame 11 moves upward or continues to move downward under the action of the elevator 12. During the movement, the first wedge block 3 gradually moves away from the second wedge block 4, and through the rebounding force of the reset spring 2 on the blocking pin 1, the blocking pin 1 gradually moves right. After the first wedge block 3 is not in contact with the second wedge block 4, the end of the blocking pin 1 is located in the inside of the guide rail 9 to continue to limit and block the RGV 10 on the guide rail 9, so as to avoid the RGV from falling off the guide rail 9 due to misoperation or sensor failure, and to avoid damaging the RGV.
