Description

Technical Field

[0001] This invention relates to the field of safety and fall prevention technology for multi-level parking garages, and more particularly to an electromechanical integrated vehicle safety and fall prevention device. Background Technology

[0002] In existing automated parking garages, safety anti-fall devices are installed to prevent the vehicle platform from falling due to the breakage of the lifting steel cable. For example, CN210439748U discloses a utility model patent for a safety anti-fall device and an automated parking garage with a safety anti-fall device, which solves the problem of vehicle damage and personal safety that may occur in the event of mechanical failure in traditional automated parking garages due to the lack of safety anti-fall devices.

[0003] However, the safety fall arrest devices currently used in ring-shaped multi-level parking garages cannot meet the requirements of single-sided braking. If the lifting steel cable is not completely broken, the safety fall arrest device cannot meet the activation conditions. At this time, the tension on the vehicle platform will be unbalanced, causing the platform to tilt as a whole. When the platform is fully loaded with vehicles, a serious accident will occur, posing a safety hazard. In addition, the existing safety fall arrest devices only work when the steel cable breaks, and cannot work when there is a power outage. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose an electromechanical integrated vehicle safety fall arrest device to solve the problem that existing safety fall arrest devices only work when the steel wire rope breaks, and cannot work when it is not completely broken or when there is a power outage.

[0052] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0054] like Figures 1 to 4 As shown, an electromechanical combined vehicle safety fall arrestor includes a lower pressure plate 1 with an upper pressure plate 2 mounted on top. The lower pressure plate 1 has at least four outwardly extending lower cantilever arms 3. The upper pressure plate 2 has upper cantilever arms 4 corresponding to all the lower cantilever arms 3. The top of the upper pressure plate 2 has at least four buffer devices 5 for reducing the rigid impact between the vehicle and the fall arrestor when the wire rope breaks. Each buffer device 5 is fixedly connected to the upper pressure plate 2. A wire rope protection device 6 is provided between each lower cantilever arm 3 and each upper cantilever arm 4 to prevent the fall arrestor from falling directly due to wire rope breakage and loosening. Furthermore, each upper cantilever arm 4 has a power failure protection device 7 at the end away from the upper pressure plate 2 to prevent the upper pressure plate 2 from overturning or falling when the power is off.

[0055] When the wire rope breaks, the other wire rope is fixed in place by the wire rope protection device 6. At the same time, the impact on the car and the upper pressure plate 2 is reduced by the buffer device 5, which greatly improves the safety of the device. By installing the power failure protection device 7 on the upper cantilever 4, the situation of vehicle rollover or falling can be taken into account when the power is cut off, making the safety more significant. This solves the problem that the existing safety anti-fall device only works when the wire rope breaks, and cannot work when it is not completely broken or when the power is cut off.

[0056] As an optional embodiment, the buffer device 5 includes:

[0057] The mounting base plate 8 is fixedly connected to the upper pressure plate 2;

[0058] The top plate 9 is installed on top of the bottom plate 8;

[0059] At least four guide rods 10 are evenly distributed and pass through the mounting base plate 8. One end of each guide rod 10 is fixedly connected to the mounting top plate 9, and the other end passes through the upper pressure plate 2.

[0060] At least four first springs 11 are distributed and sleeved on the guide rod 10, and the two ends of each first spring 11 abut against the mounting base plate 8 and the mounting top plate 9 respectively;

[0061] At least four first crank linkage assemblies are disposed between the mounting base plate 8 and the mounting top plate 9. All the first crank linkage assemblies are staggered with all the guide rods 10. Both ends of each first crank linkage assembly are fixedly connected to the mounting base plate 8 and the mounting top plate 9, respectively.

[0062] As an optional embodiment, the first crank linkage assembly includes:

[0063] The fixing block 12 is fixed on the mounting base plate 8;

[0064] The first connecting arm 13 has one end hinged to the top of the fixing block 12;

[0065] The second connecting arm 14 has one end hinged to the end of the first connecting arm 13 away from the fixing block 12;

[0066] Guide rail 15, one end of which is fixedly connected to the mounting top plate 9;

[0067] The first slider 16 is slidably sleeved on the guide rail 15, and the first slider 16 is hinged to the end of the second connecting arm 14 away from the first connecting arm 13.

[0068] For example, by installing the top and fixing it to the garage platform, and by installing the base plate 8 and fixing it to the upper pressure plate 2, when the wire rope protection device 6 completes its braking action, as shown in the attached... Figure 2 The fixed block 12, first connecting arm 13, second connecting arm 14, first slider 16, and guide rail 15 in the buffer device 5, together with the first spring 11 and guide rod 10, play a role in telescopic buffering, thereby reducing the rigid impact between the car and the upper pressure plate 2 when the wire rope breaks, and preventing damage. This solves the problem of preventing the car from directly impacting the upper pressure plate 2 due to the wire rope breaking.

[0069] As an optional embodiment, the wire rope protection device 6 includes:

[0070] The first multi-grooved wheel 17 is rotatably connected to the top of the upper cantilever 4, and the first multi-grooved wheel 17 is located on the upper cantilever 4 away from the upper pressure plate 2;

[0071] The second multi-grooved wheel 18 is rotatably connected to the upper cantilever 4 near the upper pressure plate 2;

[0072] H-shaped mounting bracket 19 is disposed between the first multi-grooved wheel 17 and the second multi-grooved wheel 18, and the bottom of the H-shaped mounting bracket 19 is fixedly connected to the upper cantilever 4.

[0073] A rope clamping assembly is provided on the lower cantilever 3, and one end of the rope clamping assembly passes through the upper cantilever 4;

[0074] The third multi-groove wheel 20 is disposed at the bottom of the H-shaped mounting bracket 19. A tensioning member is provided between the third multi-groove wheel 20 and the H-shaped mounting bracket 19. The third multi-groove wheel 20 is slidably mounted on the upper cantilever 4, and the third multi-groove wheel 20 is rotatably connected to the end of the rope clamping assembly away from the lower cantilever 3.

[0075] The fourth multi-grooved wheel 21 is rotatably connected to the top of the H-shaped mounting bracket 19;

[0076] The fifth multi-grooved wheel 22 is rotatably connected between the first multi-grooved wheel 17 and the H-shaped mounting bracket 19.

[0077] As an optional embodiment, the tensioning member includes:

[0078] A support plate 23 is mounted on top of the third multi-grooved wheel 20, and the bottom of the support plate 23 is rotatably connected to both ends of the third multi-grooved wheel 20.

[0079] The second spring 24 is positioned between the H-shaped mounting bracket 19 and the support plate 23, with its two ends abutting against the bottom of the H-shaped mounting bracket 19 and the top of the support plate 23, respectively.

[0080] As an optional embodiment, the rope clamping assembly includes:

[0081] Mounting frame 25 is disposed between the upper cantilever 4 and the lower cantilever 3, and the two ends of the mounting frame 25 are fixedly connected to the upper cantilever 4 and the lower cantilever 3 respectively.

[0082] The weight 26 is slidably connected inside the mounting frame 25, and both ends of the third multi-grooved wheel 20 are rotatably connected to the top of the weight 26.

[0083] Mechanical gripper 27 is fixedly mounted on the top of the lower cantilever 3, and the mechanical gripper 27 is located on the lower cantilever 3 away from the lower pressure plate 1;

[0084] The second crank linkage assembly has one end connected to the weight 26 and the other end connected to the mechanical gripper 27.

[0085] As an optional embodiment, the second crank linkage assembly includes:

[0086] A limiting frame 28 is fixed on the lower cantilever 3, and one end of the limiting frame 28 is sleeved on the drive rod of the mechanical gripper 27.

[0087] The second slider 29 is slidably connected inside the limiting frame 28, and the second slider 29 is fixedly connected to the drive rod of the mechanical gripper 27;

[0088] The third connecting arm 30 has one end hinged to the second slider 29;

[0089] The triangular active rod 31 has one end hinged to the lower cantilever 3, and the other two ends hinged to the weight 26 and the third connecting arm 30, respectively.

[0090] For example, since the parking garage is lifted by four hydraulic cylinders, wire rope protection devices 6 are installed at all four ends. If any end breaks, the mechanical grippers 27 of that section can immediately clamp the wire rope. The process is illustrated using the left end as an example. The rope winding method is as follows... Figure 3As shown, the wire rope passes sequentially from left to right through the lower ends of the first multi-grooved pulley 17, the third multi-grooved pulley 20, and the second multi-grooved pulley 18, then through the upper end of the fourth multi-grooved pulley 21 and the lower end of the fifth multi-grooved pulley 22, and finally connects to the pulley block at the left end of the automated parking garage. When the wire rope is intact, the second spring 24 is in a compressed state, and the weight 26 is stationary at a high position inside the mounting frame 25. When the wire rope breaks, the second spring 24 pops out, and the weight 26 descends. At this time, the weight 26 drives the triangular active rod 31 to rotate to the right, which pulls the third connecting arm 30 through the triangular active rod 31, causing the second slider 29 to move to the right in the limiting frame 28 as well. The mechanical gripper 27 clamps the wire rope, thereby preventing it from falling. The mechanical gripper 27 has four holes in the middle of the upper and lower pressure plates, which are specifically used to pass through four wire ropes. The working principle of the other three ends is the same.

[0091] As an optional embodiment, the power failure protection device 7 includes:

[0092] Gear 32 is rotatably connected to the side of the upper cantilever 4 away from the upper pressure plate 2;

[0093] A pawl 33 is disposed on the top of the gear 32, and one end of the pawl 33 is hinged to the upper cantilever 4;

[0094] An electromagnet 34 is disposed on the top of the pawl 33, and the electromagnet 34 is fixedly connected to the upper cantilever 4;

[0095] Two ratchet wheels 35 are respectively disposed on one side of the gear 32, and each ratchet wheel 35 is fixedly connected to one end of the gear 32.

[0096] For example, during normal operation of the automated parking garage, the electromagnet 34 is energized, the pawl 33 is attracted to the electromagnet 34, and the ratchet 35 can follow the gear 32 in normal forward and reverse rotation. In the event of a sudden power outage, the electromagnet 34 disconnects from the magnetic connection with the pawl 33, the pawl 33 descends, and it brakes the ratchet 35, preventing the gear 32 from rotating. This prevents the parking garage platform from tipping over or falling, thus ensuring that the safety anti-fall device can prevent vehicles from tipping over or falling even in the event of a power outage.
