Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent garages, and particularly relates to a lifting device for a car-carrying board, a fire-fighting device and a three-dimensional garage. Background Art

[0002] An intelligent garage is a modern parking facility integrating automation, informatization and intelligent technologies. It effectively solves the urban parking problem through functions such as automatically storing and retrieving vehicles, intelligently allocating parking spaces, and safety management. The lifting device of the car-carrying board is a key device for realizing the utilization of vertical space in an intelligent garage. It can not only lift the vehicle to different floors, thus greatly increasing the capacity of the garage, but also quickly move the vehicle on fire to specific safety facilities such as a fire-fighting pit in case of a vehicle fire, and extinguish the fire in time to prevent the spread of the fire.

[0003] However, in the existing lifting devices of car-carrying boards, the design structures of the lifting chain and the balance chain are usually relatively complex, and the installation and adjustment are inconvenient. The balance chain is usually arranged in the same direction. When the balance chain in the same direction is overloaded, the car-carrying board is prone to pitching, affecting the balance of the car-carrying board. At the same time, in order to realize the lifting of the car-carrying board, it is usually necessary to set up an installation frame around the lifting device, which requires a large space. In order to ensure the balance during the lifting process of the car-carrying board, a large space is also required to accommodate the balance chain and the sprocket, so that the lifting device of the car-carrying board cannot be installed in scenarios with limited space such as a fire-fighting pit. Summary of the Utility Model

[0061] The technical solution of the present utility model will be described in detail below with reference to specific embodiments and the accompanying drawings of the specification.

[0062] As shown in the Figure 1 - attached Figure 9 drawing, in a schematic embodiment of a lifting device for a car-carrying board of the present utility model, the lifting device includes a car-carrying board 1, a bottom fixed plane, a lifting drive mechanism 2, and a balance mechanism 3.

[0063] Among them, the car-carrying board 1 is horizontally arranged and is a rectangular plate-like structure. The two ends in its length direction are respectively a first end and a second end. A first fixed plane 8 is formed at the first end of the car-carrying board 1, and a first fixed plane 9 is formed at the second end of the car-carrying board 1.

[0064] The first fixed plane 8 and the second fixed plane 9 are used to install the lifting drive mechanism 2 and the balance mechanism 3, and provide a supporting force for the lifting device during the lifting process of the car-carrying board 1; the first fixed plane 8 and the second fixed plane 9 can be horizontal planes or vertical planes. When both the first fixed plane 8 and the second fixed plane 9 are horizontal planes, the first fixed plane 8 and the second fixed plane 9 can be in the same horizontal plane or in different horizontal planes. When both the first fixed plane 8 and the second fixed plane are vertical planes, the first fixed plane 8 and the second fixed plane are oppositely arranged.

[0065] The bottom fixed plane is located below the car-carrying board 1, not shown in the figure, and is used to install the balance mechanism 3. The bottom fixed plane is a horizontal plane.

[0066] The lifting drive mechanism 2 includes a drive motor 21 and a transmission chain assembly 22; the drive motor 21 is arranged at the first end and / or the second end of the car carrier plate 1, and is connected to the car carrier plate 1 through the transmission chain assembly 22 to drive the car carrier plate 1 to lift between the first fixed plane 8, the second fixed plane 9 and the bottom fixed plane. In this embodiment, the drive motor 21 is arranged at the second end of the car carrier plate 1 and is fixed on the second fixed plane 9 through a mounting seat.

[0067] The balance mechanism 3 includes a first-direction balance chain 33, a second-direction balance chain 34 and at least one set of balance sprockets.

[0068] Each set of balance sprockets includes a first balance sprocket 31 and a second balance sprocket 32. The first balance sprocket 31 is mounted at the bottom of the first end of the car carrier plate 1 through a sprocket mounting seat, and the position of the second balance sprocket 32 corresponds to that of the first balance sprocket 31 and is mounted at the bottom of the second end of the car carrier plate 1 through a sprocket mounting seat. In this embodiment, the structures and dimensions of the first balance sprocket 31 and the second balance sprocket 32 are the same.

[0069] As shown in the Figure 2 - attached Figure 4 figure, the length of the first-direction balance chain 33 is fixed and includes at least one. It is arranged below the car carrier plate 1. One end of the first-direction balance chain 33 is fixedly connected to the first fixed plane 8 through a first chain fixing seat 61, and the other end successively bypasses the first balance sprocket 31 in the same set of balance sprockets from below, bypasses the second balance sprocket 32 in the same set of balance sprockets from above, and extends vertically downward, and is fixedly connected to the bottom fixed plane below the car carrier plate 1 through a second chain fixing seat 62. The connection position of the other end of the first-direction balance chain 33 on the bottom fixed plane corresponds to the second balance sprocket 32 and is close to the second fixed plane 9; after the first-direction balance chain 33 is connected, the projection of the chain between the first balance sprocket 31 and the second balance sprocket 32 in the vertical direction is parallel to the length direction of the car carrier plate 1, and the chain between the second balance sprocket 32 and the bottom fixed plane is vertically arranged.

[0070] As shown in the Figure 5 - attached Figure 6As shown, the length of the second-direction balance chain 34 is fixed, including at least one, which is arranged below the car carrier plate 1 and is spaced from the first-direction balance chain 33. One end of the second-direction balance chain 34 is fixedly connected to the second fixed plane 9 through the first chain fixing seat 61, and the other end sequentially bypasses the second balance sprocket 32 in the same set of balance sprockets from below, bypasses the first balance sprocket 31 in the same set of balance sprockets from above, and extends vertically downward, and is fixedly connected to the bottom fixing plane below the car carrier plate 1 through the second chain fixing seat 62. The connection position of the other end of the second-direction balance chain 34 on the bottom fixing plane corresponds to the first balance sprocket 31 and is close to the first fixed plane 8; after the second-direction balance chain 34 is connected, the projection of the chain between the first balance sprocket 31 and the second balance sprocket 32 in the vertical direction is parallel to the length direction of the car carrier plate 1, and the chain between the first balance sprocket 31 and the bottom fixing plane is vertically arranged.

[0071] In this embodiment, as shown in the attached Figure 2 - attached Figure 6 As shown, the lengths of the first-direction balance chain 33 and the second-direction balance chain 34 are equal but the connection directions are opposite. During the lifting and lowering of the car carrier plate 1, the first-direction balance chain 33 and the second-direction balance chain 34 cooperate with each other and run synchronously to further ensure the balance of the car carrier plate 1.

[0072] When the lifting drive mechanism 2 drives the car carrier plate 1 to descend, in the first-direction balance chain 32, the chain section between the first balance sprocket 31 and the first fixed platform 8 continuously increases, and the chain section between the second balance sprocket 33 and the bottom end fixed platform continuously shortens; in the first-direction balance chain 32, the chain section between the second balance sprocket 34 and the second fixed platform 9 continuously increases, and the chain section between the first balance sprocket 31 and the bottom end fixed platform continuously shortens.

[0073] When the lifting drive mechanism 2 drives the car carrier plate 1 to ascend, in the first-direction balance chain 33, the chain section between the first balance sprocket 31 and the first fixed platform 8 continuously shortens, and the chain section between the second balance sprocket 32 and the bottom end fixed platform continuously increases; in the first-direction balance chain 33, the chain section between the second balance sprocket 34 and the second fixed platform 9 continuously shortens, and the chain section between the first balance sprocket 31 and the bottom end fixed platform continuously increases.

[0074] The present utility model arranges the drive motor 21 and the transmission chain assembly 22 on one side of the car carrier plate 1, and the structure is more simple and reasonable, making the installation and adjustment of the lifting drive mechanism 2 more convenient.

[0075] In order to ensure the balance of the car-carrying board 1 during the lifting process, a balance mechanism 3 is provided at the bottom of the car-carrying board 1, and the connection mode of the balance chain is optimized, so that the first-direction balance chain 33 and the second-direction balance chain 34 are connected in the opposite direction. During the lifting process of the car-carrying board 1, the first-direction balance chain 33 and the second-direction balance chain 34 will run synchronously to ensure that the forces on the first end and the second end in the length direction of the car-carrying board 1 are balanced, realizing the maintenance of the level of the car-carrying board 1. This connection mode not only saves the installation space around the car-carrying board 1, enabling the lifting device to be applicable to application scenarios where the space around the car-carrying board 1 is limited during the lifting process, such as a fire pit 7, but also effectively prevents the phenomenon of skip teeth caused by excessive force on the balance chains in the same direction, improving the running stability of the lifting device.

[0076] In order to achieve better cooperation between the first-direction balance chain 33 and the second-direction balance chain 34 and further ensure the balance of the car-carrying board 1 during the lifting process, as an implementation form of the present utility model, the second-direction balance chain 34 is arranged along the center line of the car-carrying board 1; the first-direction balance chain 33 includes two, which are respectively arranged on both sides in the width direction of the car-carrying board 1, and the two first-direction balance chains 33 are symmetrically arranged with respect to the second-direction balance chain 34 to ensure the force balance at the left, middle, and right points at both ends of the car-carrying board 1.

[0077] In order to achieve better cooperation between the first-direction balance chain 33 and the second-direction balance chain 34 and further ensure the balance of the car-carrying board 1 during the lifting process, as another implementation form of the present utility model, the first-direction balance chain 33 is arranged along the center line of the car-carrying board 1; the second-direction balance chain 34 includes two, which are respectively arranged on both sides in the width direction of the car-carrying board 1, and the two second-direction balance chains 34 are symmetrically arranged with respect to the first-direction balance chain 33 to ensure the force balance at the left, middle, and right points at both ends of the car-carrying board 1.

[0078] In order to achieve better cooperation between the first-direction balance chain 33 and the second-direction balance chain 34 and further ensure the balance of the car-carrying board 1 during the lifting process, as an implementation form of the present utility model, both the first-direction balance chain 33 and the second-direction balance chain 34 include two. The arrangement mode of the four balance chains is that the first-direction balance chain 33 is arranged on the outside, the second-direction balance chain 34 is arranged on the inside, or the first-direction balance chain 33 is arranged on the inside, the second-direction balance chain 34 is arranged on the outside, or the first-direction balance chain 33 and the second-direction balance chain 34 are arranged at intervals. It should be noted that for each arrangement mode, the positions of the four balance chains need to be evenly distributed to ensure the force balance at the four points at both ends of the car-carrying board 1.

[0079] In order to disengage the lifting sprocket 231 from the motor while the lifting drive mechanism 2 drives the car carrier plate 1 to lift through the drive chain assembly 22, and avoid damage to the drive mechanism caused by excessive force when the lifting drive mechanism 2 operates, in some embodiments of the present utility model, as shown in the appended Figure 1 and the appended Figure 7 figures, the lifting drive mechanism 2 further includes a lifting shaft 23. The lifting shaft 23 is fixed on the first fixed plane 8 or the second fixed plane 9 through a bearing fixing bracket 251 and a bearing seat 252 which are connected to each other. Among them, the bearing fixing bracket 251 is connected to the lifting shaft 23, and the bearing seat 252 is connected to the first fixed plane 8 or the second fixed plane 9. The lifting shaft 23 is directly or indirectly connected to the output shaft of the drive motor 21 and rotates under the drive of the output shaft of the drive motor 21. Lifting sprockets 231 are provided at both ends of the lifting shaft 23 in the length direction.

[0080] The drive chain assembly 22 includes a lifting chain 221. A lifting chain 221 is meshed and connected to each lifting sprocket 231, and one end of the lifting chain 221 is connected to the car carrier plate 1. In this connection mode, the force exerted by the lifting chain 221 on the sprocket is borne by the bearing seat 252.

[0081] When the lifting drive mechanism 2 drives the car carrier plate 1 to lift through the drive chain assembly 22, the lifting shaft 23 rotates, and the lifting sprocket 231 and the lifting chain 221 cooperate with each other to provide power for the lifting operation of the car carrier plate 1, thereby ensuring the feasibility of the device operation.

[0082] In order to ensure the balanced force during the lifting process of the car carrier plate 1, in some embodiments of the present utility model, there are two lifting shafts 23. The two lifting shafts 23 are respectively arranged at the first end and the second end of the car carrier plate 1 and are installed on the first fixed plane 8 and the second fixed plane 9 through the bearing fixing bracket 251 and the bearing seat 252. One of the lifting shafts 23 is connected to the output shaft of the drive motor 21. The two lifting shafts 23 altogether include four lifting sprockets 231, and the four lifting sprockets 231 are altogether meshed and connected with four lifting chains 221. The four lifting chains 221 are respectively connected to the four corners of the car carrier plate 1 to ensure the balanced force during the lifting process of the car carrier plate 1.

[0083] In some embodiments of the present utility model, the lifting drive mechanism 2 further includes a transmission shaft 24. The transmission shaft 24 is fixed on the first fixed plane 8 or the second fixed plane 9 through a bearing fixing bracket 251 and a bearing seat 252 which are connected to each other. Among them, the bearing fixing bracket 251 is connected to the transmission shaft 24, and the bearing seat 252 is connected to the first fixed plane 8 or the second fixed plane 9. The transmission shaft 24 is coaxially connected to the output shaft of the drive motor 21 and is arranged parallel to the lifting shaft 23.

[0084] A first drive sprocket 241 is provided on the drive shaft 24; a second drive sprocket 242 is provided on the lifting shaft 23, and the first drive sprocket 241 is spaced apart from the lifting sprockets 231 at both ends thereof.

[0085] The drive chain assembly 22 includes a drive chain 222, and the first drive sprocket 241 and the second drive sprocket 242 are connected by the drive chain 222.

[0086] It should be noted that, in this embodiment, the force exerted by the chain on the sprocket is borne by the bearing seat 252, which can effectively prevent the lifting drive mechanism 2 from being damaged due to excessive force during operation. At the same time, when the drive mechanism is working, the force on the drive chain 222 is transmitted from the bearing seat 252 above the bearing fixing bracket 251, and the bearing fixing bracket is used to ensure the center distance between the two sprockets, which can ensure that the chain will not skip teeth due to the reduction of the center distance, and is beneficial to improving the stability and reliability of the lifting device operation.

[0087] In some embodiments of the present utility model, as shown in the attached Figure 1 As shown, two support columns 4 are provided at the first end of the car carrier plate 1, and the two support columns 4 are respectively arranged on both sides of the car carrier plate 1. The upper end surfaces of the two support columns 4 can be used as the first fixing plane 8 or a part of the first fixing plane 8, or the upper end surfaces of the two support columns 4 can be used as the second fixing plane 9 or a part of the second fixing plane 9. In this embodiment, both ends of the lifting shaft 23 close to the drive motor are respectively fixed on the upper end surfaces of the two support columns 4.

[0088] In order to ensure the vertical movement of the car carrier plate 1, in some embodiments of the present utility model, as shown in the attached Figure 9 As shown, it further includes a limiting mechanism 5. Specifically, the limiting mechanism 5 includes a plurality of vertically arranged chutes 51, and the plurality of chutes 51 are arranged around the car carrier plate 1 and are all connected to the car carrier plate 1 to enable the car carrier plate 1 to move vertically along the chutes 51.

[0089] In order to further ensure the vertical movement of the car carrier plate 1, in some embodiments of the present utility model, as shown in the attached Figure 8 - attached Figure 9 As shown, the limiting mechanism 5 further includes a balance bolt 52. In this embodiment, there are four balance bolts 52, which are respectively arranged at the four corners of the car carrier plate 1. One end of the balance bolt 52 is fixed on the fixed platform, and the other end is connected to the car carrier plate 1 for limiting the car carrier plate 1 during the lifting process of the car carrier plate 1.

[0090] In this embodiment, the working principle of the lifting drive mechanism 2 for driving the car carrier 1 to lift is as follows: The output shaft of the drive motor 21 rotates, driving the transmission shaft 24 to rotate. The transmission shaft 24 drives the lifting shaft 23 to rotate through the transmission chain 222. The rotation of the lifting shaft 23 further causes the lifting chain 221 connecting the lifting shaft 23 and the car carrier 1 to shorten or elongate. When the lifting chain 221 connecting the lifting shaft 23 and the car carrier 1 shortens, the car carrier 1 moves vertically upward along the chute 51. When it reaches the highest point, the car carrier 1 is limited by the balance pin 52. When the lifting chain 221 connecting the lifting shaft 23 and the car carrier 1 elongates, the car carrier 1 moves vertically downward along the chute 51.

[0091] Some embodiments of the present utility model further provide a fire fighting device, as shown in the attached Figure 9 figure, which includes a fire fighting pit 7 and a lifting device for the car carrier.

[0092] Among them, the fire fighting pit 7 is arranged on a platform, and its horizontal cross-section is rectangular.

[0093] The lifting device for the car carrier is the above-mentioned lifting device for the car carrier.

[0094] In the lifting device for the car carrier, the car carrier 1 is located above the fire fighting pit 7. The top plane of the platform near the first end of the car carrier 1 is used as the first fixed plane 8, the top plane of the platform near the second end of the car carrier 1 is used as the second fixed plane 9, and the bottom wall of the fire fighting pit 7 is used as the bottom fixed plane.
