[0055] Specifically, as Figures 1 to 5 shown, the lifting system according to the embodiment of the first aspect of the present utility model for a caisson garage may include: a hoisting mechanism 100, a lifting mechanism 200, and two counterweight assemblies 300.

[0056] Among them, the hoisting mechanism 100 is arranged in the machine room 1000 on the ground floor of the caisson garage. The lifting mechanism 200 is arranged in the basement floor of the caisson garage. A longitudinal movement trolley 211 for carrying vehicles is arranged on the lifting mechanism 200, and the longitudinal movement trolley 211 can move along the length direction of the lifting mechanism 200. The two counterweight assemblies 300 are arranged in the basement floor of the caisson garage and are symmetrically located at both ends of the length direction of the lifting mechanism 200. The hoisting mechanism 100 includes a rope mechanism 110. The rope mechanism 110 is used to be connected to both ends of the length direction of the lifting mechanism 200 and the two counterweight assemblies 300 respectively. The hoisting mechanism 100 is used to drive the lifting mechanism 200 and the counterweight assemblies 300 to lift and lower synchronously in opposite directions, and the counterweight assemblies 300 are used to balance the lifting load of the lifting mechanism 200.

[0057] Specifically, as Figures 1 to 5 shown, for the lifting system according to the present utility model, a hoisting mechanism 100, a lifting mechanism 200, and two counterweight assemblies 300 are arranged in the machine room 1000 on the ground floor of the caisson garage. Taking vehicle storage as an example, a longitudinal movement trolley 211 for carrying vehicles is arranged on the lifting mechanism 200. After the vehicle drives into the entrance and exit, the vehicle storage and retrieval device on the longitudinal movement trolley 211 hooks the vehicle onto the longitudinal movement trolley 211, and then the hoisting mechanism 100 drives the lifting mechanism 200 to descend through the rope mechanism 110. At the same time, the counterweight assemblies 300 rise synchronously in the opposite direction to the lifting mechanism 200 to balance the lifting load of the lifting mechanism 200. At the same time, the longitudinal movement trolley 211 moves along the length direction of the lifting mechanism 200 to move the vehicle to a position corresponding to the designated parking space. When the lifting mechanism 200 reaches the floor of the designated parking space, the vehicle can be sent to the designated parking space through a vehicle storage and retrieval device such as a chain pulling device. When taking a vehicle, the principle is the same as that of vehicle storage, and the description thereof is omitted here.

[0058] Therefore, the lifting system provided by the present utility model sets a longitudinal moving trolley 211 on the lifting mechanism 200. By using the longitudinal moving trolley 211 to move in the length direction of the lifting mechanism 200, the vehicle is moved to the parking position beside the designated parking space. This form improves the utilization rate of the hoistway space, is conducive to increasing the number of parking spaces in the caisson garage, and compared with the existing lifting and slewing mechanisms used in the caisson garage, it reduces the waiting time of users during the peak period of vehicle access and improves the efficiency of vehicle access and storage. Moreover, in the lifting system provided by the present utility model, two counterweight assemblies 300 are located at both ends of the lifting mechanism 200, effectively balancing the lifting load. The longitudinal moving trolley 211 is arranged on the lifting mechanism 200, with a compact structure, reducing the occupation of the hoistway space, improving the space utilization rate, and enabling more parking spaces to be set up.

[0059] In some embodiments of the present utility model, as Figures 1 to 2 shown, the hoisting mechanism 100 further includes: a drum 120 and a first driving member (not shown). One end of the rope mechanism 110 is wound around the drum 120, and the other end of the rope mechanism 110 is respectively connected to both ends in the length direction of the lifting mechanism 200 and two counterweight assemblies 300. The first driving member is used to be connected to the drum 120 to drive the drum 120 to rotate. That is to say, the hoisting mechanism 100 drives the drum 120 to rotate through the first driving member, and then drives the rope mechanism 110 to drive the lifting system and the counterweight assembly 300 to lift and lower synchronously and in opposite directions, with a simple structure and stable lifting.

[0060] In some embodiments of the present utility model, as Figures 1 to 2 shown, the rope mechanism 110 includes: two first steel wires 111 and two second steel wires 112. One end of one of the first steel wires 111 is wound around the drum 120 and the other end is connected to one end in the length direction of the lifting mechanism 200. One end of the other first steel wire 111 is wound around the drum 120 and the other end is connected to the other end in the length direction of the lifting mechanism 200. One end of one of the second steel wires 112 is wound around the drum 120 and the other end is connected to one of the counterweight assemblies 300. One end of the other second steel wire 112 is wound around the drum 120 and the other end is connected to the other counterweight assembly 300. That is to say, during the operation of the hoisting mechanism 100, when the first steel wire 111 is wound by the drum 120, the lifting mechanism 200 descends. At the same time, the second steel wire 112 is unwound by the drum 120, so that the counterweight assembly 300 and the lifting mechanism 200 rise synchronously and in opposite directions. Thus, through the coordinated action of the two first steel wires 111, the two second steel wires 112 and the two counterweight assemblies 300, the stability of the lifting process is effectively ensured, and the multiple steel wires and the multiple counterweight assemblies 300 further improve the stability and reliability of the lifting system.

[0061] In some embodiments of the present utility model, asFigures 1 to 2 As shown, the hoisting mechanism 100 further includes two first pulley assemblies 130. The first pulley assemblies 130 are used to cooperate with the first steel wire ropes 111 one by one. Each first pulley assembly 130 includes: a first fixed pulley 131 and a first movable pulley 132. The first fixed pulley 131 is used to be arranged in the machine room 1000, and the first movable pulley 132 is used to be arranged at the end of the lifting mechanism 200 in the length direction. Wherein, one end of the first steel wire rope 111 far away from the drum 120 passes through the corresponding first fixed pulley 131 and first movable pulley 132 and is fixed in the machine room 1000. The first fixed pulley 131 and the first movable pulley 132 can be one, two or more. Thus, by arranging the first pulley assemblies 130, when the drum 120 rotates, the lifting direction of the first steel wire rope 111 is guided, the sway caused by the change of the tension of the first steel wire rope 111 is avoided, the stable progress of the lifting process is ensured, and it is also more labor-saving.

[0062] In some embodiments of the present utility model, as Figures 1 to 2 As shown, the hoisting mechanism 100 further includes two second pulley assemblies 140. The second pulley groups are used to cooperate with the second steel wire ropes 112 one by one. Each second pulley assembly 140 includes: a second fixed pulley 141 and a second movable pulley 142. The second fixed pulley 141 is used to be arranged in the machine room 1000, and the second movable pulley 142 is used to be arranged on the counterweight assembly 300. Wherein, one end of the second steel wire rope 112 far away from the drum 120 passes through the corresponding second fixed pulley 141 and second movable pulley 142 and is fixed in the machine room 1000. The second fixed pulley 141 and the second movable pulley 142 can be one, two or more. Similarly, by arranging the second pulley assemblies 140, when the drum 120 rotates, the lifting direction of the second steel wire rope 112 is guided, the sway caused by the change of the tension of the first steel wire rope 111 is avoided, the stable progress of the lifting process is ensured, and it is also more labor-saving.

[0063] In some embodiments of the present utility model, as Figures 3 to 5 As shown, the lifting mechanism 200 includes: a lifting platform 210, a second driving member (not shown), and a guiding mechanism 220.

[0064] Wherein, the lifting platform 210 is arranged in the lifting passage of the caisson garage. The longitudinal moving trolley 211 is arranged on the lifting platform 210. A longitudinal moving track (not shown) matching with the longitudinal moving trolley 211 is arranged in the length direction of the lifting platform 210. The second driving member is arranged on the lifting platform 210, and the second driving member is used to drive the longitudinal moving trolley 211 to move along the longitudinal moving track. The guiding mechanism 220 is arranged in the vertical direction and is used to cooperate with the lifting platform 210, and the lifting platform 210 is lifted along the guiding mechanism 220.

[0065] That is to say, the hoisting mechanism 100 drives the lifting platform 210 to lift through the first steel wire rope 111 and the first pulley assembly 130, and the guiding mechanism 220 ensures the stable lifting of the lifting platform 210 in the vertical direction. A longitudinal movement track matching with the longitudinal movement trolley 211 is arranged in the length direction of the lifting platform 210, which is used to guide the movement of the longitudinal movement trolley 211 in the length direction of the lifting platform 210. Thus, by setting the guiding mechanism 220, the stability of the lifting platform 210 during the lifting process of accessing vehicles is further ensured. The setting of the longitudinal movement track and the second driving member enables parking spaces to be arranged in the length direction of the lifting platform 210 in the hoistway, further increasing the number of parking spaces per floor and improving the utilization rate of the hoistway space.

[0066] In some embodiments of the present invention, as Figures 3 to 5 shown, the lifting platform 210 is formed into a plate girder structure, and the guiding mechanism 220 includes four groups, and the four groups of guiding mechanisms 220 are respectively arranged at the four corners of the lifting platform 210. Thus, each group of guiding mechanisms 220 cooperates with the corresponding corner of the lifting platform 210 to ensure the stable lifting of the lifting platform 210 along a predetermined path, avoid the horizontal offset of the lifting platform 210, and improve the stability of the lifting system.

[0067] In some embodiments of the present invention, as Figures 3 to 5 shown, each group of guiding mechanisms 220 includes: two guiding wheels 221 and a vertical guide rail 222. The two guiding wheels 221 are respectively arranged at the upper and lower ends of the lifting platform 210, the vertical guide rail 222 is arranged on the library body frame 500 in the lifting channel along the vertical direction, and the guiding wheels 221 are used to roll up and down along the vertical guide rail 222. That is to say, the hoisting mechanism 100 drives the lifting platform 210 to lift through the first steel wire rope 111 and the first pulley assembly 130. The upper and lower two guiding wheels 221 respectively arranged at the four corners of the lifting platform 210 cooperate with the vertical guide rail 222 arranged on the library body frame 500 in the lifting channel to ensure the stable lifting of the lifting platform 210 in the vertical direction and avoid its horizontal offset. Compared with the design of setting a single guiding wheel 221, the design of arranging two guiding wheels 221 at the upper and lower ends of the lifting platform 210 also further improves the stability of the lifting system.

[0068] In some embodiments of the present invention, as Figures 3 to 5As shown, the lifting system also includes a leveling device 230, which is installed on the lifting mechanism 200 and is used to cooperate with the leveling latch 400 of each parking space on each floor of the caisson garage. When the lifting mechanism 200 reaches the floor of the designated parking space, the leveling device 230 extends into the leveling latch 400. The leveling device 230 is usually equipped with a sensor to stop the leveling device 230 near the leveling latch 400, ensuring that the lifting mechanism 200 can accurately park at the designated parking space level. In addition, the leveling latch 400 can be a bell-shaped mouth to facilitate the insertion of the leveling roller of the leveling device 230, thereby realizing the anti-fall function and eliminating the height error between the parking and retrieval device and the parking space.

[0069] According to the second embodiment of the utility model, the sunken well garage is as follows: Figures 1 to 5 As shown, it includes a lifting system according to any embodiment of the first aspect. The caisson garage of the present invention also includes a garage frame 500 and a machine room 1000, etc. The garage frame 500 is provided with multiple parking spaces in sequence along the vertical direction. The garage frame 500 is also provided with a maintenance platform corresponding to each parking space and a ladder corresponding to each maintenance platform, etc., which will not be described in detail here. Figure 3 As shown, the caisson garage of the present invention may include two lifting channels, each of which is provided with a lifting system according to the first embodiment described above, and multiple layers of parking spaces are provided on both sides of each lifting system, which is equivalent to setting up two independently operated garages in the shaft. Especially during the peak hours of storing and retrieving cars, the efficiency is doubled compared to traditional caisson garages.

[0070] Based on the above-mentioned embodiments of the present invention, in the absence of explicit negation or conflict, the technical features of one embodiment may be beneficially combined with one or more other embodiments.

[0071] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
