Description

Technical Field

[0001] This invention relates to the field of parking equipment technology, and in particular to a hydraulic rear cantilever PSH parking equipment. Background Technology

[0002] With economic development, the number of cars in my country is increasing, causing parking difficulties. In order to expand parking capacity, some parking lots have developed parking equipment for professional parking management companies to increase parking capacity, revenue, and parking fee income. Among them, PSH is an important component of multi-level parking garages.

[0003] Existing PSH parking equipment includes hydraulic rear cantilever garages. When drivers park their vehicles on the garage, the vehicle's position may shift due to differences in driver skill. During the lifting process, the vehicle may be misaligned, which could lead to collisions between the car body and the internal mechanisms of the automated parking system, affecting its safe use. Alternatively, if the motor-operated braking system malfunctions, or if the steel cable or chain breaks, the entire pallet system may fall, posing a danger to both the vehicle and personnel. Summary of the Invention

[0010] Preferably, the fall protection mechanism includes a hydraulic column, a compression spring, a friction plate, and a bracket. The hydraulic column is symmetrically fixed on the inner walls of both sides of the frame. A compression spring fixed on the inner wall of the frame is provided on one side of the hydraulic column. One end of the hydraulic column and the compression spring is connected to the friction plate. The bracket is rotatably mounted on the inner wall of the frame in the middle of the friction plate. One side of the friction plate abuts against the outer wall of the first slider.

[0011] Preferably, the lifting pallet is divided into three sections, including an adjustment and centering mechanism and a base plate. The adjustment and centering mechanism is located at both ends of the lifting pallet, and the base plate is located in the middle of the lifting pallet.

[0012] Preferably, the adjustment and centering mechanism includes a V-shaped plate and a second guide rail. The V-shaped plate is disposed on one side of the lifting tray, and the second guide rail is disposed on the bottom plate of the V-shaped plate. Fixed limiting components fixed on the slider are disposed at both ends of the second guide rail.

[0013] Preferably, the fixed limiting assembly includes a limiting groove plate, a first hydraulic push rod, a connecting rod, a connecting roller, a bearing seat, a limiting fixing plate, an electric telescopic base, and a turntable. The limiting groove plate is fixed on a slider on a second guide rail. A hole is cut in the middle of the limiting groove plate. Two sets of first hydraulic push rods are symmetrically arranged on the two side walls of the limiting groove plate. The telescopic end of the first hydraulic push rod is hinged to the connecting rod. The other end of the connecting rod is rotatably connected to the connecting roller. The connecting roller passes through the bearing seat fixed on the limiting groove plate. The limiting fixing plate is installed in the middle of the connecting roller.

A first spring connected to the collar is set on one side of the deceleration block. An electric rotating rod passes through the middle of the collar and the top block.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention, through the cooperation of two sets of adjustment and centering mechanisms and fixed limiting components, addresses the issue that when drivers park their vehicles improperly, causing collisions between the car body and the mechanisms inside the automated parking system, the wheels, under the action of the turntable, prevent the vehicle from slipping due to excessive friction between the wheels and the pallet during centering. Subsequently, through the action of the two sets of adjustment and centering mechanisms, the originally tilted car body is kept level with the lifting pallet. Once the car body is aligned, the two limiting and fixing plates clamp inward to fix the wheels of the vehicle, preventing the vehicle from shifting during the lifting process and effectively securing the vehicle. Furthermore, the surface of the limiting and fixing plates is provided with several grooves to increase friction, allowing for a good grip on the wheel surface.

[0019] 2. This invention uses two power sources, a hydraulic rod lifting assembly and a lifting mechanism, to smoothly transport the lifting garage to a designated height. Furthermore, if one of the lifting devices fails, the lifting pallet can be smoothly placed on the ground, preventing the lifting pallet from falling rapidly to the ground due to loss of power and posing a danger to vehicles and personnel.

[0020] 3. The present invention uses a first slider and an anti-fall mechanism to work together. During the lifting process, the first slider is pulled up to a specified height by a hook. When the lifting mechanism malfunctions or the lifting pallet reaches the specified height, the anti-fall mechanism can lock the first slider to secure the lifting garage. The anti-fall mechanism has a simple overall structure, low manufacturing cost, and fast response speed.

[0021] 4. This invention, through the cooperation of the first slider and the deceleration mechanism, when the lifting mechanism malfunctions and the I-beam lifting block lacks lifting force, under the tension of the tension spring, the I-beam lifting block will touch the trigger block. The trigger block sends an electrical signal to the PLC controller, and the PLC controller controls the deceleration mechanism to start working. The deceleration mechanism abuts against the inner wall of the frame through two deceleration blocks, reducing the speed of the lifting pallet. The overall structure of the deceleration mechanism is simple, and with the anti-fall mechanism, it can ensure the smooth descent of the lifting pallet, ensuring the safety of vehicles and personnel.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figure 1-9A hydraulic rear cantilever PSH parking device includes a frame 1. The interior of the frame 1 is hollow to reduce the overall weight of the parking device. A base frame 101 is provided at the bottom of the frame 1, and a top plate 2 is provided at the top of the frame 1. Lifting mechanisms 3 are provided at both ends of the top plate 2. A backup power supply is also provided on the top plate 2. A first slider 4 is connected to the bottom of the lifting mechanism 3 and is located inside the frame 1. One end of the first slider 4 is hinged to a hydraulic telescopic rod 6. An electric slider 7 is provided at the telescopic end of the hydraulic telescopic rod 6. Two symmetrical electric sliders 7 are respectively connected to the slide grooves of the side plate of the lifting tray 8 on one side of the frame 1. The electric sliders 7 keep the lifting tray 8 in a horizontal state when the lifting tray 8 rises and falls. An anti-fall mechanism 5 is provided inside the frame 1. The outer wall of the first slider 4 abuts against the anti-fall mechanism 5. When the lifting mechanism 3 malfunctions or the lifting tray 8 reaches the specified height, the anti-fall mechanism 5 can lock the first slider 4 and fix the lifting tray 8 stably. A deceleration mechanism 10 is provided below the first slider 4, and a hydraulic rod lifting assembly 11 is provided below the deceleration mechanism 10.

[0034] The lifting mechanism 3 includes a servo motor 301, a sprocket 302, and a reel 303. The servo motor 301 is located on both sides of the top plate 2. A reel 303 is located on one side of the servo motor 301. The chain of the reel 303 is connected to the sprocket 302 located below. A hook is located below the sprocket 302. The servo motor 301 drives the reel 303 to rise, and the reel 303 winds the cable to pull the sprocket 302 to rise. By setting two sets of power sources, the lifting mechanism 3 lifts the lifting pallet 8 from above, and the hydraulic rod lifting assembly 11 supports the lifting pallet 8 from below, so that the lifting pallet 8 can rise and fall smoothly. Compared with the existing equipment that usually uses a single set of power sources to lift the garage, the two sets of power sources can ensure that even if one set of power fails, the other set still has power, which can place the lifting pallet 8 smoothly on the ground and ensure the safety of vehicles and personnel.

[0035] The first slider 4 is connected inside the frame 1. The first slider 4 has a cavity 402 inside. An I-beam lifting block 403 is set at the top of the cavity 402. A tension spring 404 is set below the I-beam lifting block 403. A trigger block 405 is connected below the tension spring 404. When the chain breaks or the servo motor 301 fails, the I-beam lifting block 403 lacks lifting force. Under the tension of the tension spring 404, the I-beam lifting block 403 will touch the trigger block 405. The trigger block 405 sends an electrical signal to the PLC controller. The PLC controller controls the anti-fall mechanism 5 to start working. The overall response speed is fast and the structure is simple. In the power failure state, the device is equipped with a backup power supply on the top plate 2. The backup power supply is electrically connected to the PLC controller, trigger block 405, anti-fall mechanism 5, deceleration mechanism 10 and hydraulic rod lifting assembly 11 of the device. A lifting ring is set at the top of the I-beam lifting block 403. The hook below the sprocket 302 is connected to the lifting ring on the I-beam lifting block 403.

[0036] The fall arrest mechanism 5 includes a hydraulic column 501, a compression spring 502, a friction plate 503, and a bracket 504. The hydraulic column 501 is symmetrically fixed on the inner walls of both sides of the frame 1. A compression spring 502, fixed on the inner wall of the frame 1, is provided on one side of the hydraulic column 501. One end of the hydraulic column 501 and the compression spring 502 is connected to the friction plate 503. The bracket 504, which is rotatably mounted on the inner wall of the frame 1, is located in the middle of the friction plate 503. One side of the friction plate 503 abuts against the outer wall of the first slider 4. When the trigger block 405 is activated... When triggered, or when the lifting pallet 8 reaches the designated position, the anti-fall mechanism 5, under the control of the PLC controller, extends the bottom hydraulic column 501 and retracts the top hydraulic column 501. At this time, the space inside the frame 1 is larger at the top and smaller at the bottom. The bottom of the first slider 4 abuts against the friction plate 503. Because the friction plate 503 is in an inclined state, the first slider 4 is stuck and cannot descend. The anti-fall mechanism 5 can fix the first slider 4. Moreover, the overall structure of the anti-fall mechanism 5 is simple and the response speed is fast.

[0037] The lifting pallet 8 is divided into three sections, including the adjustment and centering mechanism 9 and the base plate. The adjustment and centering mechanism 9 is located at both ends of the lifting pallet 8, and the base plate is located in the middle of the lifting pallet 8.

[0038] The centering adjustment mechanism 9 includes a V-shaped plate 901 and a second guide rail 902. The V-shaped plate 901 is set on one side of the lifting pallet 8, and the second guide rail 902 is set on the bottom plate of the V-shaped plate 901. The two ends of the second guide rail 902 are fixed limit components 12 fixed on the slider. During the operation of the two sets of centering adjustment mechanisms 9, the wheels will not slip due to excessive friction during centering under the action of the turntable 1208. Under the action of the two sets of centering adjustment mechanisms 9, the originally tilted car body is kept horizontal with the lifting pallet 8, reducing the possibility of the car body colliding with the mechanism inside the three-dimensional parking garage due to improper parking by the driver.

[0039] The fixed limiting assembly 12 includes a limiting groove plate 1201, a first hydraulic push rod 1202, a connecting rod 1203, a connecting roller 1204, a bearing seat 1205, a limiting fixing plate 1206, an electric telescopic base 1207, and a turntable 1208. The limiting groove plate 1201 is fixed on a slider on the second guide rail 902. A hole is cut in the middle of the limiting groove plate 1201. Two sets of first hydraulic push rods 1202 are symmetrically arranged on the two side walls of the limiting groove plate 1201. The telescopic end of the first hydraulic push rod 1202 is hinged to the connecting rod 1203. The other end of the connecting rod 1203 is rotatably connected to the connecting roller 1204. The connecting roller 1204 passes through the bearing seat fixed on the limiting groove plate 1201. 1205, A limiting and fixing plate 1206 is inserted through the middle of the connecting roller 1204. The surface of the limiting and fixing plate 1206 is provided with several grooves to increase friction, which can grip the surface of the wheel well. Both limiting and fixing plates 1206 clamp inward to fix the wheel of the vehicle, preventing the vehicle from deviating during the lifting process and effectively fixing the vehicle. An electric telescopic base 1207 is provided in the hole in the middle of the limiting groove plate 1201. A turntable 1208 is provided at the upper end of the electric telescopic base 1207. When the electric telescopic base 1207 lifts the wheel, the wheel will not slip due to excessive friction during the straightening process under the action of the turntable 1208.

[0040] The hydraulic rod lifting assembly 11 includes a hydraulic rod 1101 and a hydraulic rod slider 1102. The hydraulic rod 1101 is located inside the frame 1. The hydraulic rod 1101 is sleeved on the hydraulic rod 1102, which can move up and down. One side of the hydraulic rod slider 1102 is connected to the side wall of the lifting tray 8. When the hydraulic rod lifting assembly 11 is powered on, the hydraulic rod slider 1102 can drive the lifting tray 8 to move upward smoothly.

[0041] The deceleration mechanism 10 includes a collar 1001, an electric rotating rod 1002, a top block 1003, and a deceleration block 1004. One end of the collar 1001 is connected to the side wall of the lifting tray 8, and the other collar 1001 is disposed inside the frame 1. The top block 1003 is disposed between the two collars 1001, and deceleration blocks 1004 are disposed on both sides of the top block 1003. The deceleration blocks 1004 slide on the collar 1001 via guide rails. A first spring 1005 is disposed on one side of the deceleration block 1004 and connected to the collar 1001. The collar 1001 and the top block 1004 are connected to the top block 1001. An electric rotating rod 1002 passes through the middle of the 003. The deceleration mechanism 10 can support the two sets of deceleration blocks 1004 by rotating the top block 1003 when the first slider 4 loses its lifting force or when the lifting pallet 8 reaches the specified height. The deceleration blocks 1004 abut against the inner wall of the frame 1, thus fixing the lifting pallet 8. The overall structure of the deceleration mechanism 10 is relatively simple. In conjunction with the anti-fall mechanism 5, the two can quickly support the lifting pallet 8 when it falls. Finally, the lifting pallet 8 can be placed steadily on the ground to ensure the safety of vehicles and personnel.

[0042] In use, the driver parks the vehicle on the lifting pallet 8, with the vehicle wheels resting on the front and rear V-shaped plates 901. After the driver gets out of the vehicle, the two adjustment and centering mechanisms 9 and the fixed limiting assembly 12 of the lifting pallet 8 are connected to an external power source and begin operation. The extended end of the electric telescopic base 1207 lifts the vehicle upward by 1-2 cm, causing the vehicle wheels to leave the lifting pallet 8. The electric block on the second guide rail 902 drives the fixed limiting assembly 12 to run on the second guide rail 902. During the operation of the two sets of adjustment and centering mechanisms 9, the wheels, under the action of the turntable 1208, prevent the vehicle from slipping due to excessive friction during centering. Under the action of the two sets of adjustment and centering mechanisms 9, the originally tilted vehicle body is aligned with the lifting pallet 8. Maintaining a horizontal position, once the vehicle and the lifting pallet 8 are level, the electric telescopic base 1207 begins to descend. The vehicle's wheels abut against the horizontal limiting fixing plate 1206. The limiting fixing plate 1206 has several grooves on its surface to increase friction, effectively gripping the wheel surface. At this time, the first hydraulic push rod 1202 begins to operate. The extended end of the first hydraulic push rod 1202 extends and rotates forward against the connecting rod 1203. The connecting rod 1203 drives the connecting roller 1204 to rotate, which in turn drives the middle limiting fixing plate 1206 to rotate. Both the front and rear limiting fixing plates 1206 clamp inward, fixing the vehicle's wheels and preventing the vehicle from shifting during ascent, thus effectively securing the vehicle.

[0043] After the vehicle's position is adjusted, the PLC controller controls the lifting mechanism 3 and the hydraulic rod lifting assembly 11 to connect to an external power source and begin operation. The output shaft of the servo motor 301 drives the winding drum 303 to move, and the winding drum 303 begins to reel in the wire. The hook below the sprocket 302 drives the first slider 4 to move upward. The hydraulic telescopic rod 6, which is hinged to the first slider 4, is pulled upward under traction. The extended end of the hydraulic telescopic rod 6 drives the electric slider 7 to move upward together. The electric slider 7 passes through the middle of the lifting pallet 8 and drives the lifting pallet 8 to move upward. The hydraulic rod lifting assembly 11 connects to an external power source, and the hydraulic rod 1101 rotates, driving the hydraulic rod slider 1102 to move upward. The hydraulic rod slider 1102, connected to the bottom end of the lifting pallet 8, moves upward. Under the combined action of the lifting mechanism 3 and the hydraulic rod lifting assembly 11, the lifting pallet 8 moves smoothly upward. Through the two sets of lifting mechanisms, the lifting pallet 8 can be smoothly transported to the designated position.

[0044] When the lifting pallet 8 moves to the designated position, the PLC controller controls the anti-fall mechanism 5 to connect the external power supply and the deceleration mechanism 10. Under the control of the PLC controller, the extended end of the hydraulic column 501 at the bottom of the anti-fall mechanism 5 extends out, and the extended end of the hydraulic column 501 at the top retracts. At this time, the space inside the frame 1 is larger at the top and smaller at the bottom. The bottom end of the first slider 4 abuts against the friction plate 503. Because the friction plate 503 is in an inclined state, the first slider 4 is stuck and cannot descend. The PLC controller controls the electric rotating rod 1002 to rotate 90 degrees. At this time, the top block 1003 rotates simultaneously under the drive of the electric rotating rod 1002. The two ends of the top block 1003 abut against the deceleration block 1004. The deceleration block 1004 expands outward along the guide rail. At this time, the two deceleration blocks 1004 abut against the inner wall of the frame 1 and lock the deceleration mechanism 10. The lifting pallet 8 connected to the deceleration mechanism 10 is fixed.

[0045] When the machine malfunctions, such as the servo motor 301 stopping or the sling breaking, the lifting pallet 8 descends too quickly. The first slider 4 loses tension and moves downwards. The I-beam lifting block 403 is pulled downwards by the tension spring 404. The bottom of the I-beam lifting block 403 touches the trigger block 405, which outputs an electrical signal to the PLC controller. The PLC controller then controls the extension end of the hydraulic column 501 at the bottom of the fall arrestor 5 to extend, while the extension end of the upper hydraulic column 501 retracts. At this time, the space inside the frame 1 is wider at the top and narrower at the bottom. The bottom of the first slider 4 abuts against the friction plate 503. Because the friction plate 503 is tilted, the first slider 4... When slider 4 is stuck and cannot descend, the PLC controller controls the deceleration mechanism 10, and the electric rotating rod 1002 rotates 90 degrees. At this time, the top block 1003 rotates simultaneously under the drive of the electric rotating rod 1002. The two ends of the top block 1003 abut against the deceleration block 1004, and the deceleration block 1004 expands outward along the guide rail. At this time, the two deceleration blocks 1004 abut against the inner wall of the frame 1 and lock the deceleration mechanism 10. The lifting pallet 8 connected to the deceleration mechanism 10 is fixed. The anti-fall mechanism 5 and the deceleration mechanism 10 work together to quickly support the lifting pallet 8. Finally, the lifting pallet 8 can be placed steadily on the ground to ensure the safety of vehicles and personnel.
