[0040] Figure 1 FIG. 1 shows a schematic diagram of an anti-fall mechanism 100 according to an embodiment of the present utility model. Figure 2 Another schematic diagram of the anti-fall mechanism 100 according to an embodiment of the present utility model is shown below. Figure 1 and Figure 2 Describe in detail.
[0041] like Figure 1 and Figure 2 As shown, the anti-fall mechanism 100 includes a pivot 110, an anti-fall lever 120 and a counterweight 130, wherein the pivot 110 is arranged along a first direction, and the first direction may be a horizontal direction (eg Figure 1 The middle part of the anti-falling lever 120 is connected to the pivot 110, and the counterweight 130 is installed at one end of the anti-falling lever 120 (for example Figure 1 The anti-fall lever 120 is configured to be rotatable around the axis of the pivot 110. Specifically, the anti-fall lever 120 and the pivot 110 may be fixedly connected, and the two may rotate together around the axis of the pivot 110. The anti-fall lever 120 and the pivot 110 may be movably connected, and the anti-fall lever 120 may rotate relative to the pivot 110. The anti-fall lever 120 has a blocking position and an avoidance position. The anti-fall lever 120 may switch between the blocking position and the avoidance position by rotating around the axis of the pivot 110. Specifically, the anti-fall lever 120 is suitable for being driven by the hoist to the avoidance position (details will be described later). Under the influence of gravity, the counterweight 130 may cause the anti-fall lever 120 to reset to the blocking position. When the anti-fall lever 120 is in the blocking position (for example Figure 1As shown), the anti-falling lever 120 can block the four-way shuttle vehicle and prevent the four-way shuttle vehicle from rushing out of the shelf track 210; when the anti-falling lever 120 is in the avoidance position, the anti-falling lever 120 will no longer affect the passage of the four-way shuttle vehicle.
[0042] According to one embodiment of the utility model, Figure 1 and Figure 2 As shown, the anti-falling lever 120 may include a blocking portion 121 and a counterweight portion 122 connected to each other, wherein a counterweight block 130 is connected to one side of the counterweight portion 122 (eg Figure 1 The length of the blocking portion 121 is greater than the length of the counterweight portion 122, and an angle of 105°-165° is formed between the blocking portion 121 and the counterweight portion 122 to reduce the anti-falling gear lever 120 in Figure 1 The space occupied by the left and right directions in the middle makes the anti-falling mechanism 100 Figure 1 The left and right directions are more compact, which prevents the anti-fall mechanism 100 from affecting other equipment and components in the vertical warehouse shelf 200.
[0043] Figure 3 A schematic diagram of an anti-falling gear lever 120 according to an embodiment of the utility model is shown. Figure 3 As shown, Figure 1 and Figure 3 As shown, a first through hole 123 may be provided at a position of the blocking portion 121 close to the counterweight portion 122. The pivot 110 passes through the anti-falling lever 120 through the first through hole 123 and is rotationally matched with the anti-falling lever 120 (first through hole 123).
[0044] According to one embodiment of the utility model, Figure 1 and Figure 2 As shown, a reinforcing rib 125 may be provided on the blocking portion 121 to enhance the structural strength of the blocking portion 121 so that the blocking portion 121 is not easily bent by the four-way shuttle. Preferably, the reinforcing rib 125 is formed by bending the edge of the blocking portion 121, for example Figure 1 In the illustrated embodiment, the upper edge and the lower edge of the blocking portion 121 are both bent forward and form reinforcing ribs 125 , respectively.
[0045] According to one embodiment of the utility model, Figure 1 and Figure 3 As shown, a waist-shaped hole 124 can be provided on the counterweight portion 122 of the anti-falling lever 120, and the length direction of the waist-shaped hole 124 is substantially parallel to the length direction of the counterweight portion 122. Figure 1 and Figure 3As shown, a second through hole (not shown) is provided on the counterweight 130. The anti-fall mechanism 100 may further include a bolt 140, which passes through the second through hole on the counterweight 130 and the waist-shaped hole 124 on the anti-fall lever 120 in sequence, and locks the counterweight 130 on the counterweight portion 122. The user can adjust the position of the counterweight 130 on the counterweight portion 122 (the anti-fall lever 120) by loosening the bolt 140, and then adjust the center of gravity of the assembly composed of the counterweight 130 and the anti-fall lever 120, so that when the anti-fall lever 120 is in the blocking position, the center of gravity of the assembly is directly below the pivot 110, so that after the anti-fall lever 120 rotates, the anti-fall lever 120 can be reset to the blocking position under the action of gravity.
[0046] According to one embodiment of the utility model, Figure 1 and Figure 2 As shown, the anti-fall mechanism 100 may further include a fixing seat 150, and the pivot 110 is connected to the fixing seat 150, wherein the pivot 110 may be a bolt, and a threaded hole (not shown in the figure) is provided on the fixing seat 150, and the connection between the pivot 110 and the fixing seat 150 can be achieved by screwing the pivot 110 into the threaded hole. The fixing seat 150 can be used to connect with the column 220 or the guide rail of the vertical warehouse shelf 200, and specifically, a plurality of third through holes 151 are provided on the fixing seat 150, and the third through holes 151 can cooperate with a fixing member (such as a screw) to install the fixing seat 150 on the column 220 or the guide rail.
[0047] According to one embodiment of the utility model, Figure 1 and Figure 2 As shown, a positioning pin 160 can be provided on the fixing seat 150, and the positioning pin 160 can limit the rotation angle of the anti-falling lever 120, avoid the blocking portion 121 and the counterweight portion 122 of the anti-falling lever 120 from being replaced, and improve the reliability of the anti-falling mechanism 100. Figure 1 As shown, the blocking portion 121 of the anti-fall lever 120 is located on the right side of the pivot 110, and the counterweight portion 122 is located on the left side of the pivot 110. By setting a positioning pin 160, it is possible to prevent the blocking portion 121 from rotating to the left side of the pivot 110 and the counterweight portion 122 from rotating to the right side of the pivot 110.
[0048] Figure 4 , Figure 5 and Figure 6 The schematic diagrams of the vertical warehouse shelf 200 according to an embodiment of the utility model are shown respectively. Figures 4 to 6 Describe in detail.
[0049] like Figures 4 to 6As shown, the vertical warehouse rack 200 includes a rack rail 210, a hoist (not shown) and the anti-fall mechanism 100 as described above. The rack rail 210 can be provided with one or more layers ( Figures 4 to 6 210), the shelf track 210 can be set on the column 220, and the column 220 provides support for the shelf track 210. The shelf track 210 has an entrance and exit 211, and the four-way shuttle can enter or exit the shelf track 210 through the entrance and exit 211. The anti-fall mechanism 100 is set at the entrance and exit 211 of the shelf track 210. The elevator includes a lifting basket and a lifting device (the lifting basket and the lifting device are not shown in the figure), wherein the lifting device is used to drive the lifting basket to do lifting and lowering movements, and the lifting basket is used to carry the four-way shuttle to move between the multiple layers of the shelf track 210 to realize the layer change of the four-way shuttle. A collision block 230 is provided on the lifting basket, and the position of the collision block 230 corresponds to the position of the anti-fall mechanism 100. When the lifting basket is docked with the entrance and exit 211 of the shelf rail 210, the collision block 230 prompts the anti-fall lever 120 of the anti-fall mechanism 100 to rotate to the avoidance position so that the four-way shuttle vehicle can pass between the lifting basket and the shelf rail 210.
[0050] like Figure 4 As shown, when the lifting basket is not docked with the shelf track 210 , the anti-falling lever 120 of the anti-falling mechanism 100 is in a blocking position, and the anti-falling lever 120 can prevent the four-way shuttle vehicle from rushing out of the entrance and exit 211 of the shelf track 210 .
[0051] like Figure 5 As shown, when the lifting basket moves from the bottom of the shelf rail 210 to the state where it is flush with the shelf rail 210 (the lifting basket is docked with the shelf rail 210), the collision block 230 pushes the anti-falling gear bar 120 to the avoidance position, and the anti-falling gear bar 120 loses its blocking effect, and the four-way shuttle can pass between the lifting basket and the shelf rail 210. When the lifting basket leaves the shelf rail 210 (that is, after the lifting basket moves upward or downward), the collision block 230 leaves the anti-falling gear bar 120, and the anti-falling gear bar 120 is reset to the blocking position under the action of gravity.
[0052] like Figure 6 As shown, when the lifting basket moves from above the shelf rail 210 to a state where it is flush with the shelf rail 210 (the lifting basket is docked with the shelf rail 210), the collision block 230 presses the anti-falling gear bar 120 down to the avoidance position, and the anti-falling gear bar 120 loses its blocking effect, and the four-way shuttle can pass between the lifting basket and the shelf rail 210. When the lifting basket leaves the shelf rail 210, the collision block 230 leaves the anti-falling gear bar 120, and the anti-falling gear bar 120 is reset to the blocking position under the action of gravity.
[0053] According to one embodiment of the utility model, Figure 4 As shown, two anti-falling mechanisms 100 can be provided at the entrance and exit 211 of each shelf track 210, and the two anti-falling mechanisms 100 are symmetrically installed on both sides of the entrance and exit 211 ( Figure 4 Correspondingly, two collision blocks 230 are arranged on the lifting basket, and the two collision blocks 230 correspond to the two anti-falling mechanisms 100 in position.
[0054] Compared with the prior art, the embodiment of the utility model provides an anti-fall mechanism 100 and a vertical warehouse shelf 200, wherein the anti-fall mechanism 100 has a simple mechanical structure, is easy to install and maintain, and the anti-fall lever 120 can switch between a blocking position and an avoidance position by relying on gravity and the movement of the elevator, without the need to configure an additional power source and electrical control system.
[0055] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
