Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically to a parking elevator. Background Technology

[0002] Multi-story parking garages can solve the problem of high parking space demand. The vertical expansion of space in multi-story parking garages multiplies the original parking space many times over. Currently, some multi-story parking garages use vertical elevators to transport cars. However, existing multi-story parking garages use traditional building structures, and in order to save space and provide more parking spaces, the space at the elevator entrance is limited. Furthermore, when cars enter the elevator car, the standard design of the elevator doors can be too narrow for some vehicles, potentially causing collisions and accidents for inexperienced drivers.

[0003] A search revealed that CN109339528B discloses an elevator for a multi-level parking garage. The elevator includes a car, a steel wire rope for pulling the car, a traction system for pulling and releasing the steel wire rope, a guide system for guiding the car up and down, a door system on each floor, a gravity balancing system for balancing the load on the car, a safety protection system to ensure elevator safety, a car carrier device for carrying cars waiting to be parked, a first turntable device, a conveying device, and a position identification device. The elevator loads cars onto the car carrier device, which then automatically rotates the turntable. Without requiring the car to drive into the elevator, the car is automatically pushed into the elevator car by the conveying device from the car carrier device, avoiding collisions due to narrow elevator openings or operator unfamiliarity, thus achieving safe car transport and parking in the multi-level parking garage.

[0004] However, the above-mentioned parking garage elevator still has the following problems: In order to adjust the position of the vehicle, the above-mentioned parking garage elevator has a turntable system on each floor. The turningtable system and the vehicle loading plate device work together to turn the vehicle and load it into the elevator. This multi-turntable system increases the construction cost, and the structural layout of the turntable makes the original elevator design space more confined, thus affecting the overall layout of the elevator. Summary of the Invention

[0005] This invention proposes a parking elevator that solves the problems of increased construction costs and impact on the overall layout of elevators caused by multi-turntable systems in the prior art.

[0006] The technical solution of the present invention is as follows: A parking elevator includes a car, a parking platform located outside the car, a car-carrying device located inside the car, and a conveying device for moving the car-carrying device between the car and the parking platform. A drop frame for vehicles to park laterally relative to the car is placed on the top of the parking platform. The car-carrying device includes a turntable, a top plate, and a trolley arranged horizontally from top to bottom. A lifting mechanism is provided between the trolley and the top plate, which pushes the turntable to lift the drop frame and the vehicle above it after the trolley enters the parking platform. A baffle is fixed at the middle of the bottom surface of the top plate. A stop plate is fixed on the top surface of the trolley, which abuts against the baffle to keep the drop frame lifted above the top surface of the parking platform. A drive mechanism is provided on the top plate to drive the turntable to rotate the drop frame and the vehicle above it to face the car. A buffer mechanism is provided on the trolley to buffer the drop frame when it is lowered.

[0007] Preferably, the lifting mechanism includes a shaft with connecting rods rotatably connected to both ends. One end of the connecting rod is hinged to a first hinge seat fixed to the top surface of the trolley, and the other end is hinged to a second hinge seat fixed to the bottom surface of the top plate. A U-shaped seat is rotatably connected to the middle of the shaft, and a movable shaft is rotatably connected to the end of the U-shaped seat away from the shaft. An L-shaped pressure rod is provided in the middle of the movable shaft, and a limiting groove for the movable shaft to pass through is provided on the L-shaped pressure rod. A third hinge seat fixed to the top surface of the trolley is hinged to the bottom of the L-shaped pressure rod. The conveying device inside the car sends the car-carrying device out of the car and moves it into the parking platform below the lowering frame. The clamping plate on the top surface of the turntable can be moved from the bottom of the lowering frame... One end of the slot slides in. When the trolley enters the enclosure, the L-shaped pressure rod, under the resistance of the inner wall of the enclosure, begins to push the U-shaped seat. The U-shaped seat pushes the shaft, causing the connecting rod to rotate counterclockwise. During this process, due to the rotation of the connecting rod, the height of the top plate and the turntable is gradually raised. The turntable can then lift the drop frame and the vehicle parked on it upwards, making them higher than the top surfaces of the first and second supports, until the baffle on the bottom surface of the top plate abuts against the stop plate on the top surface of the trolley. When the stop plate and the baffle abut, the angle between the connecting rod and the top surface of the trolley is less than 90 degrees. Therefore, after the trolley moves out of the parking platform, the connecting rod can tend to rotate clockwise and then press against the buffer mechanism.

[0008] Preferably, the drive mechanism includes a motor, which is fixedly embedded in the bottom of the top plate. A gear is fixed to the output shaft end of the motor. A rotating ring that is rotatably connected to the top plate is fixed to the bottom of the turntable. The outer ring surface of the rotating ring is provided with an annular tooth surface that meshes with the gear. When the turntable lifts the car frame and the vehicle parked on the car frame upwards, and the baffle above the top surface of the first and second support platforms comes into contact with the stop plate on the top surface of the top plate, the motor can work to drive the gear to rotate. The meshing of the gear with the annular tooth surface on the outer ring surface of the rotating ring can drive the turntable to rotate. In turn, the engagement of the clamping plate with the clamping groove at the bottom of the car frame will drive the car frame and the vehicle parked on the car frame to rotate, so that the vehicle is facing the car.

[0009] Preferably, the buffer mechanism includes a slide block, which is fixed to the top surface of the trolley. A slider is slidably connected to the inner side of the slide block. A pad for supporting the shaft is fixed to the top of the slider. A spring damper is provided at the bottom of the slider and abuts against the top surface of the trolley. The pressure is transmitted to the spring damper by the support of the shaft by the pad, and then the spring damper buffers the impact force during the fall.

[0010] Preferably, the vehicle lowering frame has guard plates on both sides to prevent the vehicle from deviating. One end of the vehicle lowering frame has two protruding strips on its top surface to facilitate the positioning of the front wheels. The bottom surface of the vehicle lowering frame has two slots perpendicular to the length direction of the vehicle lowering frame. The top surface of the turntable is fixed with a plate that can slide and engage with the two slots. Driven by a motor, the engagement of the plate with the slots at the bottom of the vehicle lowering frame can rotate the vehicle lowering frame and the vehicle parked on it, thereby adjusting the vehicle's position.

[0011] Preferably, the parking platform includes a first platform, a second platform opposite to the first platform, and a retaining plate fixed at both ends to the first platform and the second platform respectively. The top surfaces of the first platform and the second platform are provided with grooves adapted to the vehicle lowering frame. The second platform is provided with a ramp and side rails located on both sides of the ramp to guide the vehicle to park correctly.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. This invention uses the lifting mechanism to lift the vehicle-carrying device by contacting the parking platform, causing the top plate and turntable on the vehicle-carrying device to lift the vehicle-carrying frame upwards. The drive mechanism then drives the turntable to adjust the vehicle's position, protecting the vehicle's stability without requiring manual operation to drive the car into the elevator car. Compared to existing technologies, the vehicle's position can be adjusted using only the vehicle-carrying device, eliminating the need for turntables on each floor, thus saving design costs and solving the problems of increased construction costs and impact on the overall elevator layout caused by multiple turntable systems in existing technologies.

[0014] 2. In this invention, when the stop plate and the baffle are in contact, the angle between the connecting rod and the top surface of the trolley is less than 90 degrees. Therefore, after the trolley moves out of the parking platform, the connecting rod can tend to rotate clockwise and press against the buffer mechanism. The pressure is transmitted to the spring damper by the support of the axle by the pad of the buffer mechanism. The spring damper then buffers the impact force during the fall to ensure the smooth fall of the vehicle. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1 and Figure 2 This invention provides a technical solution: a parking elevator, including a car 1, a parking platform 3 located outside the car 1, a car-carrying device 2 located inside the car 1, and a conveying device for moving the car-carrying device 2 between the car 1 and the parking platform 3. A drop frame 4 for vehicles to park laterally relative to the car 1 is placed on the top of the parking platform 3. The car-carrying device 2 includes a turntable 23, a top plate 22, and a trolley 21 arranged horizontally from top to bottom. A lifting mechanism 25 is provided between the trolley 21 and the top plate 22, which, when the trolley 21 enters the parking platform 3, pushes the turntable 23 to lift the drop frame 4 and the vehicle above it. A baffle 28 is fixed at the center of the bottom surface of the top plate 22. A stop plate 27 is fixed on the top surface of the trolley 21, which abuts against the baffle 28 to keep the drop frame 4 lifted above the top surface of the parking platform 3. The invention is equipped with a drive mechanism 24 that drives the turntable 23 to rotate the upper drop frame 4 and the vehicle to face the car 1. The trolley 21 is equipped with a buffer mechanism 26 to buffer the drop frame carrying the vehicle when the top plate 22 is lowered. The invention uses the lifting mechanism 25 to abut against the parking platform 3, so that the top plate 22 and the turntable 23 on the vehicle carrier 2 lift the drop frame carrying the vehicle upward. The drive mechanism 24 drives the turntable 23 to adjust the position of the vehicle. The invention protects the stability of the vehicle without the need for manual operation to drive the car into the car 1. Compared with the prior art, the vehicle position can be adjusted by the vehicle carrier 2 alone, without the need to set up turntables 23 on each floor. This saves design costs and solves the problems of increased construction costs and impact on the overall layout of the elevator caused by the multiple turntable system in the prior art.

[0030] Please see Figure 2 and Figure 3The lifting mechanism 25 includes a shaft 254, with connecting rods 253 rotatably connected to both ends of the shaft 254. One end of the connecting rod 253 is hinged to a first hinge seat 251 fixed to the top surface of the trolley 21, and the other end of the connecting rod 253 is hinged to a second hinge seat 252 fixed to the bottom surface of the top plate 22. A U-shaped seat 255 is rotatably connected to the middle of the shaft 254, and a movable shaft 258 is rotatably connected to the end of the U-shaped seat 255 away from the shaft 254. An L-shaped pressure rod 257 is provided in the middle of the movable shaft 258, and a limiting groove 259 is provided on the L-shaped pressure rod 257 for the movable shaft 258 to pass through. A third hinge seat 256 fixed to the top surface of the trolley 21 is hinged to the bottom of the L-shaped pressure rod 257. The conveying device in the car 1 sends the car-carrying device 2 out of the car 1 and moves it into the parking platform 3 below the drop frame 4. The card plate 233 on the top surface of the turntable 23 can be moved by the drop frame 4. One end of the slot 43 at the bottom of frame 4 slides in. When the trolley 21 enters the enclosure 35, the L-shaped pressure rod 257, under the resistance of the inner wall of the enclosure 35, begins to push the U-shaped seat 255. The U-shaped seat 255 pushes the shaft 254, causing the connecting rod 253 to rotate counterclockwise. During this process, due to the rotation of the connecting rod 253, the height of the top plate 22 and the turntable 23 is gradually raised, so that the turntable 23 can then lift the lowering frame 4 and the lowering frame. The vehicle parked on the 4th floor is lifted upwards and becomes higher than the top surface of the first platform 31 and the second platform 32, until the baffle 28 on the bottom surface of the top plate 22 abuts against the stop plate 27 on the top surface of the trolley 21. When the stop plate 27 abuts against the baffle 28, the angle between the connecting rod 253 and the top surface of the trolley 21 is less than 90 degrees. Therefore, when the trolley 21 moves out of the parking platform 3, the connecting rod 253 can tend to rotate clockwise and then press against the buffer mechanism 26.

[0031] Please see Figure 5 The drive mechanism 24 includes a motor 241, which is fixedly embedded in the bottom of the top plate 22. A gear 242 is fixed to the output shaft end of the motor 241. A rotating ring 231, which is rotatably connected to the top plate 22, is fixed to the bottom of the turntable 23. The outer ring surface of the rotating ring 231 is provided with annular toothed surfaces 232 that mesh with the gear 242. The turntable 23 lifts the drop frame 4 and the vehicle parked on the drop frame 4 upwards, making them higher than the top of the first support platform 31 and the second support platform 32. When the baffle 28 on the bottom surface of the top plate 22 comes into contact with the stop plate 27 on the top surface of the trolley 21, the motor 241 can work to drive the gear 242 to rotate. The meshing of the gear 242 with the annular tooth surface 232 on the outer ring of the rotating ring 231 can drive the turntable 23 to rotate. Then, the engagement of the clamping plate 233 with the bottom groove 43 of the drop frame 4 will drive the drop frame 4 and the vehicle parked on the drop frame 4 to rotate 90 degrees, so that the vehicle is facing the car 1.

[0032] Please see Figure 3 and Figure 4The buffer mechanism 26 includes a slide 261, which is fixed to the top surface of the trolley 21. A slider 262 is slidably connected to the inner side of the slide 261. A pad 263 for supporting the shaft 254 is fixed to the top of the slider 262. A spring damper 264 is provided at the bottom of the slider 262 and abuts against the top surface of the trolley 21. The pressure is transmitted to the spring damper 264 by the pad 263 supporting the shaft 254, and then the spring damper 264 buffers the impact force when falling.

[0033] Please see Figure 6 and Figure 7 The vehicle drop frame 4 has guard plates 41 on both sides to prevent the vehicle from deviating. The top surface of one end of the vehicle drop frame 4 has two protruding strips 42 to facilitate the positioning of the front wheels. The bottom surface of the vehicle drop frame 4 has two slots 43 perpendicular to the length direction of the vehicle drop frame 4. The top surface of the turntable 23 is fixed with a plate 233 that can slide and engage with the two slots 43. Driven by the motor 241, the engagement of the plate 233 with the slots 43 at the bottom of the vehicle drop frame 4 can drive the vehicle drop frame 4 and the vehicle parked on the vehicle drop frame 4 to rotate, thereby adjusting the position of the vehicle.

[0034] Please see Figure 8 The parking platform 3 includes a first platform 31, a second platform 32 opposite to the first platform 31, and a retaining plate 35 fixed at both ends to the first platform 31 and the second platform 32 respectively. The top surfaces of the first platform 31 and the second platform 32 are provided with grooves 36 that are adapted to the vehicle drop frame 4. The second platform 32 is provided with a ramp 33 and side rails 34 on both sides of the ramp 33 to guide the vehicle to park correctly.

[0035] The working principle and usage process of this invention are as follows: The vehicle first travels along the ramp 33 on the side where the second support platform 32 is located to the drop frame 4, and stops when the front wheels pass the first raised strip 42. Then, the conveying device in the car 1 sends the vehicle carrying device 2 out of the car 1 and moves it into the parking platform 3 below the drop frame 4. At this time, the device... Figure 9 As shown, the card plate 233 on the top surface of the turntable 23 can slide into one end of the slot 43 at the bottom of the drop frame 4. When the trolley 21 enters the enclosure 35, the L-shaped pressure rod 257, under the contact of the inner wall of the enclosure 35, begins to push the U-shaped seat 255. The U-shaped seat 255 pushes the shaft 254, causing the connecting rod 253 to rotate counterclockwise. During this process, due to the rotation of the connecting rod 253, the height of the top plate 22 and the turntable 23 is gradually raised. Then, the turntable 23 can lift the drop frame 4 and the vehicle parked on the drop frame 4 upwards, making them higher than the top surfaces of the first support platform 31 and the second support platform 32, until the baffle 28 on the bottom surface of the top plate 22 contacts the stop plate 27 on the top surface of the trolley 21. At this time, the device is as follows: Figure 10As shown, the motor 241 then operates, driving the gear 242 to rotate. The meshing of the gear 242 with the annular tooth surface 232 on the outer ring of the rotating ring 231 rotates the turntable 23. This, in turn, causes the card plate 233 to engage with the slot 43 at the bottom of the lowering frame 4, rotating the lowering frame 4 and the vehicle parked on it by 90 degrees, so that the vehicle faces the car 1. At this time, the device functions as follows: Figure 11 As shown, the vehicle carrier 2 and the vehicle loaded on the vehicle carrier 2 can then be sent into the car 1 by the conveying device, so as to be raised and lowered to other floors.

[0036] During the above process, when the baffle 28 on the bottom surface of the top plate 22 abuts against the stop plate 27 on the top surface of the trolley 21, the angle between the connecting rod 253 and the top surface of the trolley 21 is less than 90 degrees. Therefore, after the trolley 21 moves out of the parking platform 3, the connecting rod 253 can tend to rotate clockwise and press against the buffer mechanism 26. The pressure is transmitted to the spring damper 264 by the pad 263 on the buffer mechanism 26 supporting the shaft 254. The spring damper 264 then buffers the impact force during the fall, thereby protecting the falling vehicle and preventing the vehicle from sliding relative to the vehicle carrier 2 during the fall.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
