Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical parking garages, and relates to lifting and traversing parking garages, specifically an energy-saving hydraulically driven lifting and traversing parking garage. Background Technology
[0002] With the development of the national economy and the gradual improvement of people's living standards, more and more families own private cars, and the demand for parking facilities is constantly increasing. How to make full use of existing space to park more vehicles has become an urgent problem to be solved. Although the most common underground parking lots can solve some parking problems, they occupy a large area and are prone to congestion. Moreover, car owners need to park and retrieve their vehicles themselves, which also wastes time. Therefore, multi-level parking garages have emerged. Multi-level parking garages can be mainly divided into lift-and-slide type, vertical circulation type, lane stacking type, vertical lift type, and simple lift type according to different principles. Among them, lift-and-slide type multi-level parking garages are the most common.
[0003] Lift-and-slide automated parking systems use lifting or sliding platforms to store and retrieve vehicles. These systems can be built outdoors or underground, offering advantages such as ease of maintenance and lower cost. A common lift-and-slide automated parking system has a two-story structure: two sliding platforms on the first floor and three lifting platforms on the second floor. Currently, the power units for lift-and-slide automated parking systems are generally electric motor-driven or hydraulic cylinder-driven.
[0004] Currently, most hydraulically driven lift-and-slide parking systems on the market use a one-cylinder-one-platform transmission mode, meaning one hydraulic cylinder drives only one lifting platform. This allows the transmission system to directly lift and lower an individual platform, but it also increases energy consumption and floor space. Meanwhile, some lift-and-slide parking systems on the market use a one-cylinder-multiple-platform transmission mode, where a single hydraulic cylinder can drive multiple different lifting platforms. However, regardless of whether it's a one-cylinder-multiple-platform or one-cylinder-one-platform transmission mode, the hydraulic motor needs to be activated to provide power for raising or lowering any platform. In other words, while the one-cylinder-multiple-platform transmission mode reduces the number of hydraulic motors, it doesn't reduce energy consumption. Utility Model Content
[0005] This invention addresses the technical problem that existing hydraulically driven lifting and sliding multi-plate parking garages still consume a lot of energy, and designs an energy-saving hydraulically driven lifting and sliding parking garage.
[0006] The technical solution adopted in this utility model is as follows:
[0007] An energy-saving hydraulically driven lifting and sliding garage includes a PLC controller, a garage frame, three lifting platforms mounted on the frame, a sliding platform below one of the lifting platforms, and a hydraulic lifter on one side of the frame. The garage frame, located at the rear of the lifting platforms, includes four columns and parallel front and rear crossbeams fixedly mounted on the tops of the columns. The sliding platform is mounted on a sliding rail, which is fixedly mounted on a plane below the lifting platforms. A lifting slider is vertically fixedly mounted at the rear of the lifting platforms. A diagonal tie rod connects the top of the lifting slider to a fixed point in the middle of the lifting platform. Vertical lifting grooves are provided on the columns of the frame, and these grooves cooperate with the lifting slider. The upper and lower ends of two lifting sliders on the same lifting platform are respectively connected and fixedly connected by a crossbar, with the center of the upper crossbar... A locking ring is provided at the top; the locking ring cooperates with an electronic locking hook that is simultaneously fixed between the front and rear crossbeams; two height limit bars are provided on both sides of the electronic locking hook; the lifting rod of the hydraulic lift is equipped with a lift pulley; the top of the four columns of the platform frame, the bottom of the column near the hydraulic lift, both ends of the crossbar above each lifting platform, and the bottom of the hydraulic lift are all equipped with pulleys, and each pulley is connected to a hysteresis brake and a speed sensor; one end of a rope is fixed to the ground below the hydraulic lift, first passing around the lift pulley from the inside to the outside, then around the pulley at the bottom of the hydraulic lift, then from the bottom to the top of the column near the hydraulic lift, then from the outside to the inside, then around the pulley at the top of the column, then passing around the two pulleys of the lifting platform from the bottom to the top, then from the top to the bottom of the next column, three times in the order of passing around the pulleys at the top of the lifting platform from the bottom to the top, and finally fixed to the ground. Furthermore, the lifting platform is also equipped with a protective frame, which is used to prevent the lifting platform above from being accidentally lowered or tilted due to operational errors or damage, which could cause damage to the traverse platform and the vehicles on it.
[0008] Furthermore, a support rod for support or reinforcement is provided between the two crossbars of the lifting vehicle.
[0009] The initial state of the above-mentioned lift-and-slide garage is as follows: two lift platforms are raised to their highest positions, and their corresponding electronic lock hooks pop out and engage with their corresponding locking rings; the other lift platform is lowered to the ground, and its corresponding electronic lock hook retracts; the slide platform is located below one of the raised lift platforms; and the hydraulic lift is in an inactive state.
[0010] When the lift-and-slide garage is in operation, it will raise one lift platform and immediately lower another lift platform (if there is a slide platform, it needs to be moved below the stationary lift platform in advance).
[0011] If the weight of the raised and lowered lifting platforms are roughly equal, or if the raised platform is heavier than the lowered platform, the hydraulic lift will first be activated to raise the platform until it reaches its highest position. At this point, the corresponding electronic locking hook will deploy. Then, the hydraulic lift will be shut off, allowing the platform to automatically descend, while the electronic locking hook for the lowered platform retracts. Due to gravity, the platform will descend rapidly. If the platform descends too quickly, and the rotational speed sensor of the corresponding pulley exceeds or equals the maximum threshold, the corresponding hysteresis brake will activate to slow the descent until the platform reaches the ground.
[0012] If the raised platform is lighter than the lowered platform, the hydraulic lift is not activated; instead, the electronic locking hook of the lowered platform is retracted directly. Because the lowered platform is heavier than the raised platform, it descends rapidly due to the difference in gravity. If the lowered platform decelerates too quickly or the raised platform rises too quickly, and the rotational speed measured by the corresponding pulley's speed sensor is greater than or equal to the maximum threshold, the corresponding hysteresis brake is activated to slow down the descent and ascent of the platform until the lowered platform reaches the ground and the raised platform reaches its highest position. Then, the electronic locking hook of the raised platform is released.
[0013] As can be seen from the above, in the aforementioned lift-and-slide parking garage, when only the lifting platform is descending or the descending platform is heavier than the rising platform, the hydraulic lift is not activated. Instead, the rotational speed of the corresponding pulley is monitored. When the speed exceeds the safe speed, the corresponding hysteresis brake is activated to slow down the pulley's rotation, allowing the lifting platform to be safely lowered or raised. The safe speed is the rotational speed at which the pulley's rotational speed is less than or equal to the speed at which damage will not occur to the lifting platform or the vehicle on it.
[0014] This utility model has the following beneficial effects:
[0015] 1. The lifting and traversing garage adopts a hydraulic transmission drive, so that when one lifting platform is raised, the other lifting platform is lowered immediately, which saves time and reduces energy consumption.
[0016] 2. When only the lifting platform is descending or the descending lifting platform is heavier than the rising lifting platform, it is not necessary to start the hydraulic lifting machine. It is only necessary to detect the pulley speed and start the corresponding hysteresis brake in time.
[0017] 3. Simple structure: one hydraulic lift can control multiple lifting platforms, reducing energy consumption. Attached Figure Description

Obviously, the embodiments described below are only some embodiments of this utility model. For those skilled in the art, other examples can be obtained based on these embodiments without creative effort.
[0023] Example 1
[0024] This embodiment relates to an energy-saving hydraulically driven lifting and sliding garage, such as... Figure 1-3As shown, the lifting and traversing parking garage includes a PLC controller (not shown in the figure), a parking platform frame 1, three lifting platforms 2 mounted on the platform frame 1, a traversing platform 3 positioned below one of the lifting platforms 2, and a hydraulic lifter 4 positioned on one side of the platform frame 1; the platform frame 1 is located at the rear end of the lifting platforms 2 and includes four columns 5 and parallel front and rear crossbeams 6 and 7 fixedly mounted on the tops of the columns 5; the traversing platform 3 is mounted on a traversing slide rail 8, which is fixedly mounted on a plane below the lifting platform 2; A lifting slider 9 is vertically fixedly installed at the rear end of the lifting platform 2; a diagonal tie rod 10 connects the top of the lifting slider 9 to the middle fixed point of the lifting platform 2; a vertical lifting groove 11 is provided on the column 5 of the platform frame 1, and the lifting groove 11 cooperates with the lifting slider 9; the upper and lower ends of the two lifting sliders 9 of the same lifting platform 2 are respectively connected and fixedly connected by a crossbar 12, and a locking ring 13 is provided above the center of the upper crossbar 12; the locking ring 13 is connected to an electronic lock that is simultaneously fixed between the front crossbeam 6 and the rear crossbeam 7. The hook 14 is used in conjunction with the hydraulic lifter 4; two height limit bars 15 are provided on both sides of the electronic lock hook 14; the lifting rod of the hydraulic lifter 4 is equipped with a lifter pulley 16; the top of the four columns 5 of the platform frame 1, the bottom of the column 5 near the hydraulic lifter 4, both ends of the crossbar 12 above each lifting platform 2, and the bottom of the hydraulic lifter 4 are all equipped with pulleys 17, and each pulley 17 is connected to a hysteresis brake and a speed sensor (the two are not shown in the figure, but are installed in accordance with the conventional method in the art); a rope 18 (for the purpose of showing the rope). The rope's trajectory (shown in its entirety in the diagram, though some sections are not actually visible) is fixed at one end to the ground below the hydraulic lift 4. It first winds around the lift pulley 16 from the inside out, then around the pulley 17 at the bottom of the hydraulic lift 4, then upwards around the pulley 17 at the bottom of the column 5 near the hydraulic lift 4, then inwards around the pulley 17 at the top of the column 5. This process is repeated three times, winds around the two pulleys 17 of the lifting platform 2 from bottom to top, then downwards around the pulley 17 at the top of the next column 5, before finally being fixed to the ground. The lifting platform 2 is also equipped with a protective frame to prevent accidental lowering or tilting of the lifting platform 2 due to operational errors or damage, which could damage the lateral moving platform 3 and the vehicles on it. A support rod 19 is provided between the two crossbars 12 of the lifting vehicle for support or reinforcement.
[0025] The initial state of the aforementioned lift-and-slide parking garage is as follows: two lift platforms are raised to their highest positions, and their corresponding electronic locking hooks extend and engage with their corresponding locking rings; the other lift platform is lowered to the ground, and its corresponding electronic locking hook retracts; the slide platform is positioned below one of the raised lift platforms, and the hydraulic lift is not activated. When a vehicle is parked in this lift-and-slide parking garage, it can be parked on either the slide platform or the lowered lift platform. When both the slide platform and the lowered lift platform are occupied, the lowered lift platform can be raised while the other empty lift platform is lowered. If there is a slide platform below the empty lift platform, the slide platform must be moved laterally to be below the stationary lift platform before or after the lowered lift platform is raised.
[0026] When retrieving a vehicle from the lift-and-slide garage, if the vehicle is on the lateral sliding platform or a lowered lift-and-slide platform, simply remove the vehicle. If there is no lateral sliding platform below the lift platform where the vehicle is located, the lowered lift-and-slide platform needs to be raised while the corresponding lift platform is lowered, and then the vehicle can be removed. If there is a lateral sliding platform below the lift platform where the vehicle is located, the lateral sliding platform needs to be moved horizontally to below the stationary lift platform after the lowered lift platform is raised or before the lowered lift platform is raised, then the corresponding lift platform is lowered, and then the vehicle can be removed.
