DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Please refer to Figure 1-3 ;

[0023] The anti-fall structure described in the present invention is intended to realize the gravity change that occurs when the vehicle supporting device 22 and the transverse comb teeth alternate, or to provide protection when the lifting device 21 chain breaks and causes falling, so as to minimize the loss; it specifically includes a frame 1, which can specifically refer to the frame 1 that constitutes the elevator shaft, or the frame 1 of the entire garage, and four support assemblies 3 are rotatably connected to the frame 1 corresponding to each floor, and the four support assemblies 3 respectively correspond to the four support parts 23 of the lifting device 21, and the four support assemblies 3 are grouped into two, and each support assembly 3 is provided with the same structure, one end of the two support assemblies 3 is respectively connected to the two pull rods 4, one end of the two pull rods 4 is connected to the pull rope device 5, and the other end is provided with a spring 61, which is driven by the pull rope device 5 to drive the support assembly 3 to self-lock and lock, and the two ends of the spring 61 are respectively in contact with the fixing member 1 62 and the fixing member 2 63, the fixing member 1 62 is arranged on the frame 1, and the fixing member 2 63 is arranged on the pull rod 4;

[0024] When the lifting device 21 needs to drive the vehicle supporting device 22 to move upward, the pull rope device 5 is in a stretched state, and the pull rod 4 moves downward under the action of the spring 61, causing the support assembly 3 to flip over and be in an unlocked state, and will not block the lifting device 21 from moving upward; after the lifting device 21 reaches the specified position, the pull rope device 5 drives the pull rod 4 to lift upward and compresses the spring 61 at the same time. When the pull rod 4 is lifted upward, the support assembly 3 will rotate in the opposite direction and reset, so that it is extended and placed in the lifting shaft to correspond to the support part 23 of the lifting device 21. When the lifting device 21 accidentally falls, its four support parts 23 respectively conflict with the four support assemblies 3, and the four support assemblies 3 support the lifting device 21, that is, to prevent the vehicle supporting device 22 from falling to the next level. After the transverse comb teeth are completed and the vehicle is moved, the support assembly 3 will be unlocked again under the action of the pull rope device 5 to make room for the lifting device 21 to move.

[0025] The utility model locks the support assembly 3 after the lifting device 21 reaches the specified position, so that the support assembly 3 is located below the support part 23, providing protection at all times during the subsequent vehicle moving process. If an accidental fall occurs, the four support assemblies 3 support the support part 23 of the lifting device 21, thereby preventing the vehicle supporting device 22 from falling to the next level.

[0026] Preferably, after the lifting device 21 drives the vehicle supporting device 22 to stabilize on one layer, the distance between the support portion 23 and the support assembly 3 is less than 5 cm, that is, when the vehicle supporting device 22 falls, it will only drop a distance of 5 cm, reducing the impact force.

[0027] In another embodiment, the spring 61 can be replaced by a tension spring. Of course, the installation method will also change. The spring 61 provides downward pressure to the pull rod 4, and the corresponding tension spring applies downward tension to the pull rod 4, which can also achieve the same technical effect. In this way, this is an equivalent structure.

[0028] One embodiment of the stretching device of the present invention specifically includes a motor 51. A winding drum 52 is provided at the output end of the motor 51. Two steel cables (not shown) are wound around the winding drum 52. Preferably, the winding drum 52 has two independent slots for accommodating the two steel cables, so that the two steel cables are extended in opposite directions and wound around the roller 53. Of course, it is also possible to use a single steel cable, for example, by cross-rotating the cable so that the cable extends in two different directions. However, it should be noted that the opposite ends can be extended or wound at the same time.

[0029] In this embodiment, two steel cables extending in opposite directions are respectively connected to two pull rods 4. When the motor 51 rotates forward, it drives the winding drum 52 to rotate, so that the steel cables at both ends are wound up, thereby driving the two pull rods 4 to lift. When the motor 51 rotates reversely, it drives the winding drum 52 to rotate in the opposite direction, so that the steel cables are in a stretched state. At the same time, the spring 61 can pull the pull rod 4 downward; preferably, the pull rod 4 needs to move up and down longitudinally, so a guide member can be set on the frame 1 to limit the position of the pull rod 4.

[0030] The support assembly 3 in the present invention has two implementation modes;

[0031] Embodiment 1 specifically includes a fixing member 311 mounted on the frame 1. The fixing member 311 is placed upright and has a limiting protrusion 312 and a support block 32 rotatably connected to its side. The end of the support block 32 is rotatably connected to a connecting rod 33. The other end of the connecting rod 33 is rotatably connected to a fixing member 4 34. The fixing member 4 is fixed to the pull rod 4. When unlocking is required, the pull rod 4 moves downward under the action of the spring 61, which simultaneously drives the fixing member 4 34 downward and pushes the connecting rod 33, ultimately driving the support block 32 away from the limiting protrusion 312, that is, rotating from a horizontal state to an upright state, thereby making room for the support portion 23 to pass through.

[0032] When locking is required, the pull rod 4 moves upward, and at the same time drives the fixing part 4 34 to move upward and pushes the connecting rod 1 33 to reset, and finally drives the support block 1 32 to rotate toward the limit protrusion 1 312, so that the bottom of the support block 1 32 contacts the limit protrusion 1 312. Under the limitation of the limit protrusion 1 312 and the rotation position, the support block 1 32 cannot move further and maintains a horizontal state. At this time, it extends out of the lifting shaft and corresponds to the support part 23.

[0033] Preferably, a second limiting protrusion 313 is provided on the fixing member 311, and the second limiting protrusion 313 can interfere with the upper end surface of the supporting block 1 32 to prevent the supporting block 1 32 from flipping too much when in the unlocked state.

[0034] The second embodiment specifically includes a fixing member 5 35 installed on the frame 1, and the fixing member 5 35 is in a horizontal fixed state. The fixing member is non-rotatably connected to a "Z"-shaped support block 2 36, wherein one end of the support block 2 36 is a supporting portion 361, which is used to extend out of the lifting shaft and correspond to the support portion 23, and the other end is rotatably connected to a connecting rod 2 37, and the end of the connecting rod 2 37 is rotatably connected to a fixing member 6 38, and the fixing member 6 38 is fixed on the pull rod 4. The specific operation method is the same as that of the first embodiment. The connecting rod 2 37 is driven by the up and down movement of the pull rod 4 to flip the support block 2 36 to realize the unlocking and locking operations. Preferably, a movable groove 362 is provided in the support block 2 36, and the connecting rod 2 37 is placed in the movable groove 362.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
