When the driving rod 10 is positioned at the bottom of the second strip through hole 6, the driving rod 10 is positioned in the movement conversion groove 11, and the projections of the bearing plate 4 and the driving rod 10 on the horizontal plane are mutually perpendicular; as the driving rod 10 moves up in the second elongated through hole 6, the driving rod 10 drives the vertical shaft 3 to rotate, and when the driving rod 10 reaches the junction of the first chute 7 and the second chute 8 along the first chute 7, the bearing plate 4 rotates to the lower part of the driving rod 10 along the vertical shaft 3.

When the car carrying plate falling protector is applied to the stereo garage, as shown in fig. 6 and 7, at least 4 groups of falling protectors can be installed on the frame of the stereo garage, so that the height of the carrying plate 4 is consistent with the height of the bottom surface of the car carrying plate 16 after the car carrying plate 16 is lifted to a high position. The anti-drop mechanism can effectively support the vehicle carrying plate 16, and normal vertical lifting of the vehicle carrying plate 16 cannot be affected. The driving rods 10 of the falling protectors are perpendicular to the edges of the vehicle carrying plate 16, and the vehicle carrying plate 16 can push the driving rods 10 to ascend simultaneously when ascending. For example, as shown in fig. 2 to 4, the sleeve 2 of each fall arrester is fixed at the bottom position of the upper layer frame 1 of the stereo garage. The bearing plate 4 can swing in the first strip through hole 5, and when the bearing plate 4 is parallel to the edge of the vehicle carrying plate 16, the vehicle carrying plate 16 can smoothly ascend through the height of the bearing plate 4; when the carrier plate 4 swings below the vehicle carrying plate 16, the carrier plate 16 can be supported, and the vehicle carrying plate 16 is prevented from accidentally descending or falling.

The second strip through hole 6 formed in the sleeve 2, the first chute 7, the second chute 8 and the vertical groove 9 formed in the peripheral surface of the vertical shaft 3 can realize guiding driving on rotation of the vertical shaft 3 in the sleeve 2. As shown in fig. 5, the first chute 7, the second chute 8 and the vertical chute 9 form a triangle on the development surface of the periphery of the vertical shaft 3, and are complete channels which are communicated end to end.

Because sleeve 2 is fixed relative to frame plate 1, that is when actuating lever 10 goes up and down vertically along rectangular through-hole 6 of second, first chute 7, second chute 8 and perpendicular groove 9 play the effect of guide way, can let vertical scroll 3 follow the lift of actuating lever 10 and produce the rotation, let loading board 4 rotate to the position that carries sweep 16 below.

According to the utility model, the bottoms of the first chute 7 and the vertical chute 9 are provided with the movable conversion chute 11 which is communicated with each other, and when the driving rod 10 is positioned in the movable conversion chute 11 and moves upwards along the second strip through hole 6, the driving rod 10 enters the first chute 7. When the driving rod 10 is located in the movement conversion groove 11, the projections of the bearing plates 4 and the driving rod 10 on the horizontal plane are perpendicular to each other, and each bearing plate 4 is parallel to the edge of the vehicle carrying plate 16, so that the vertical lifting of the vehicle carrying plate 16 cannot be interfered by each bearing plate 4. When the driving rod 10 moves up between the first chute 7 and the second chute 8, each carrying plate 4 rotates to the bottom of the carrying plate 16 below the driving rod 10, so as to form effective support for the bottom of the carrying plate 16, and at this time, if unexpected situations of out-of-control lifting or broken lifting steel ropes occur, each carrying plate 4 can prevent the carrying plate 16 from moving down or falling. When the driving rod 10 moves up to the top end of the second chute 8, the bearing plate 4 rotates to reset to an avoidance position parallel to the edge of the vehicle carrying plate 16, then the vehicle carrying plate 16 can vertically move down to a low position, the vehicle can be moved out in the stereo garage, when the vehicle carrying plate 16 moves down, the driving rod 10 descends to the movement conversion groove 11 along the vertical groove 9 under the action of self weight of the driving rod 10, and when the driving rod 10 moves down, the bearing plate 4 is always in the avoidance position.

The following describes in detail the action of each carrying plate 4 when the carrying plate 16 moves up and down vertically with reference to fig. 6-10, when the carrying plate 16 is located at the lower position of the stereo garage, as shown in fig. 2, the driving rod 10 of each falling protector is located at the bottom of the second long through hole 6 and in the movement conversion groove 11 at the same time, and each carrying plate 4 is located at the avoiding position, so that the vertical upward movement of the carrying plate 16 is not affected. When the car carrying plate 16 moves upwards, after the top surface of the car carrying plate 16 contacts with the driving rods 10 of each anti-falling device, the driving rods 10 are driven to synchronously move upwards, the driving rods 10 only move upwards vertically under the guide of the second long through holes 6, the driving rods 10 enter the first chute 7 from the moving conversion grooves 11, the bearing plates 4 at the bottoms of the driving rods are driven to swing towards the car carrying plate 16 gradually by the rotation of the vertical shafts 3 through the guide of the first chute 7 until the driving rods 10 move upwards to the top of the first chute 7, at the moment, the car carrying plate 16 moves upwards to the high position of the stereo garage, as shown in fig. 8 and 9, the bearing plates 4 completely rotate to the bottom of the bearing plates 4, and the car carrying plate 16 falls onto the bearing plates 4 to prevent unexpected falling or falling.

When the carrying plates 16 need to move downwards, the vertical limit of the carrying plates 4 on the carrying plates 16 needs to be relieved, at this time, the carrying plates 16 need to drive the driving rods 10 to move upwards in the second long through holes 6, so that the driving rods 10 enter the second chute 8 from the first chute 7, as the second chute 8 and the first chute 7 are symmetrically arranged on the horizontal line of the connecting part, the vertical shafts 3 can rotate reversely, the carrying plates 4 swing gradually and far away from the bottom of the carrying plates 4, when the driving rods 10 move upwards to the top of the second chute 8, as shown in fig. 10, the carrying plates 4 swing to be completely separated from the carrying plates 16 at this time, the carrying plates 16 can move downwards vertically, and after the driving rods 10 lose the lifting of the carrying plates 16, the driving rods can fall down through the vertical grooves 9 under the dead weight and finally fall into the moving conversion grooves 11, so that the carrying plates 16 can be driven to move upwards synchronously when moving upwards next time, and a cycle is completed. In the falling process of the driving rod 10, the bearing plate 4 cannot rotate to interfere with the vertical lifting of the vehicle carrying plate 16.

In order to ensure that the driving rod 10 is firmly arranged between the sleeve 2 and the vertical shaft 3 and avoid the separation of the driving rod 10 and the sleeve 2, the following technical scheme can be adopted: the widths of the first chute 7, the second chute 8, the vertical chute 9 and the movable transition chute 11 are larger than the width of the second long through hole 6, one end of the driving rod 10 positioned in the sleeve 2 is provided with a sliding block 12, the sliding block 12 is matched with the first chute 7, the second chute 8, the vertical chute 9 and the movable transition chute 11, and the width of the sliding block 12 is larger than the width of the second long through hole 6 so as to prevent the driving rod 10 from falling off. Wherein the slide 12 can be made of a metal material with a high density to ensure a lowering and resetting by its own weight in the vertical slot 9.

Wherein the angle between the first chute 7 and the second chute 8 may also be other than 90 degrees in order to accommodate other types of products.

In order to ensure that the driving rod 10 which is positioned in the movement conversion groove 11 enters the first chute 7 when moving upwards vertically and the driving rod 10 which is moved downwards in the vertical groove 9 can enter the bottommost position of the movement conversion groove 11, the following technical scheme can be adopted: the movable conversion slot 11 comprises a vertical edge 13, an arc edge 14 and a bevel edge 15 which are sequentially connected, and the arc edge 14 is positioned at the bottommost part of the movable conversion slot 11 and is matched with the end part of the driving rod 10. Wherein the vertical side 13 and the arc side 14 are positioned at the lower part of the first chute 7, the inclined side 15 is positioned at the lower part of the vertical chute 9, and the bottommost part of the inclined side 15 is connected with the arc side 14. When the driving rod 10 in the arc-shaped edge 14 moves upwards along the second long through hole 6, the driving rod 10 enters the first chute 7 upwards, and when the driving rod 10 in the vertical groove 9 moves downwards along the second long through hole 6, the driving rod 10 moves to the arc-shaped edge 14 along with the inclined edge 15, and the reciprocating rotation of the bearing plate 4 at the bottom of the vertical shaft 3 is completed through the vertical lifting of the driving rod 10 and the guide grooves matched with the surface of the vertical shaft 3. The above technical solution can ensure that the switching between the vertical groove 9 and the first chute 7 can be automatically completed when the driving rod 10 reaches the movement conversion groove 11, and ensure that the driving rod 10 does not return to the vertical groove 9 when moving upwards after descending. Through the technical scheme, the movement of the driving rod 10 can be completely completed under the dead weight and the driving of the vehicle carrying plate 16, no additional switching device or additional control unit is required, and the garage is safer and more reliable to operate and can realize maintenance-free within 3-5 years.

The vertical shaft 3 in the anti-falling device is provided with a chute which can force the sliding block 12 to slide at a certain angle, namely a first chute 7, a second chute 8 and a vertical chute 9. The sliding grooves are arranged at a certain angle, so that the sliding blocks 12 are forced to slide at a certain angle, and the bearing plate 4 connected with the vertical shaft 3 is driven to rotate to a position capable of preventing the vehicle carrying plate 16 from sliding down. When the sliding block 12 is driven by the vehicle carrying plate 16 to the middle position of the sliding groove, namely the position where the first chute 7 and the second chute 8 are connected, the carrying plate 4 is arranged at the position where the vehicle carrying plate 16 is prevented from falling, and when the sliding block 12 continues to ascend, the sliding block 12 is forced to reversely drive the vertical shaft 3 to link the carrying plate 4 to reversely run due to the reverse angle of the sliding groove, namely the first chute 7 and the second chute 8 are reversely arranged, so that the carrying plate 4 returns to the original position, and the normal descending of the vehicle carrying plate 16 is prevented. The slide 12 is moved to the highest point of the chute, namely the top position of the second chute 8, and then moves into the vertical chute 9, and the slide 12 falls to the original point by the self weight, so that a cycle is completed.

In the above process, the power for rotating the bearing plate 4 is derived from the vertical lifting of the vehicle carrying plate 16, and the bearing plate 4 can be driven to rotate and be positioned at the bottom of the vehicle carrying plate 16 to realize the anti-falling function without additional power input through the lifting of the vehicle carrying plate 16, so as to achieve the purpose of self-service anti-falling.
