Abstract
Description
Technical Field
[0001] This invention relates to the field of automated parking systems, specifically a four-layer chain-driven PSH parking system. Background Technology
[0002] Intelligent multi-level parking refers to parking equipment that utilizes space resources to park vehicles vertically, saving land and maximizing its use. The biggest advantage of multi-level parking systems is their ability to fully utilize urban space, earning them the title of "energy savers" for urban spaces. With the development of technology, multi-level mechanical parking garages are ubiquitous. For four-level parking systems, the chain-lift method is relatively low-cost, thus creating a need for a four-level chain-driven PSH parking system.
[0003] Currently used parking equipment often experiences shaking and vibration during the lifting process. The lifting system's initial activation pulls the comb frame upwards, causing it to sway and vibrate, which in turn causes the vehicle to shake. With prolonged use, the lifting chain is prone to breakage due to wear and the initial tension. To address this, some existing parking equipment includes emergency mechanisms to prevent the comb frame and vehicle from falling in the event of a chain breakage. These mechanisms typically involve an instantaneous locking brake to stop the comb frame, but this instantaneous braking can cause significant shaking, and the vehicle may still tilt and fall off the comb frame. The lifting system uses sensors to position the comb frame height during lifting. If the lifting system malfunctions, the vehicle may fail to stop at the top parking position, potentially causing it to collide with the top of the parking equipment. Furthermore, with prolonged use, the lifting chain may loosen, making it difficult for the comb frame to accurately stop at the designated height for different levels. Summary of the Invention
[0004] To address the problems in the prior art, the present invention provides a four-layer chain-type PSH parking device.
[0005] The objective of this invention can be achieved through the following technical solutions:
[0006] A four-layer chain-type PSH parking equipment includes a garage frame, the bottom of which is fixed to the ground. The garage frame is spliced from H-shaped steel beams. A comb frame is slidably connected to the garage frame. A lifting system is installed at the top of the garage frame. The lifting system drives the comb frame to rise and fall along the H-shaped steel beams via a chain. The comb frame includes symmetrically distributed steel frames. Emergency mechanisms are fixedly connected at both ends of the steel frames. A sliding limit mechanism is provided at the top of the steel frames.
[0007] The emergency mechanism is equipped with a first sliding block that slides with the H-shaped steel beam, a first sliding groove at the top of the steel frame, and an array of first connecting plates welded between two opposing H-shaped steel beams. An installation frame is connected to the side wall of the first connecting plate, and a support mechanism is provided inside the installation frame.
[0008] Preferably, the comb frame includes a front baffle, and the inner wall of the steel frame is provided with front comb teeth and rear comb teeth that are fixedly connected. The front baffle is located at the front end of the front comb teeth. The limiting mechanism is set on the top of the steel frame near the rear wheel of the vehicle. The garage frame is provided with a slidingly connected transverse frame at a specified height. The comb teeth of the transverse frame and the comb teeth of the comb frame are arranged alternately.
[0009] Preferably, the emergency mechanism includes a first support, one side of which is fixedly connected to the outer wall of the steel frame, and the other side of which is fixedly connected to a second support and a first sliding block. A first connecting rod is welded to the center of the side wall of the H-shaped steel beam near the second support, and a first electric cylinder is installed on the side wall of the second support near the first support.
[0010] Preferably, the first electric cylinder telescopic rod passes through the second bracket and connects to the first telescopic rod. The telescopic end of the first telescopic rod is fixedly connected to the positioning pin. A spring is wound around the outside of the first telescopic rod. A hole corresponding to the positioning pin is opened on the first connecting rod. Several holes are evenly distributed on the first connecting rod. At the same time, when the vehicle is parked on the second, third and fourth floors, there are holes at the corresponding positions of the first connecting rod.
[0011] Preferably, the inner wall of the second bracket is provided with symmetrically distributed second telescopic rods, the telescopic end of the second telescopic rod is fixedly connected to a wedge block, a spring is wound around the outside of the second telescopic rod, a second electric cylinder is installed on the outer wall of the second bracket on the side opposite to the H-shaped steel beam, the telescopic rod of the second electric cylinder passes through the second bracket and is fixedly connected to a compression block, a pull ring is fixedly connected to the top of the first sliding block, and a sliding wheel is provided inside the first sliding block.
[0012] Preferably, the limiting mechanism includes a second sliding block, a first motor is installed on one outer wall of the second sliding block, the bottom output shaft of the first motor passes through the second sliding block and is rotatably connected to a bidirectional threaded rod, a second sliding groove is provided on one side wall of the second sliding block, a slidable third sliding block is symmetrically arranged in the second sliding groove, the bidirectional threaded rod is rotatably connected to the third sliding block, the third sliding block is rotatably connected to a first baffle, and the two first baffles are simultaneously rotatably connected to the second connecting plate.
[0013] Preferably, the steel frame has an installation cavity inside, and a third electric cylinder is installed in the installation cavity. The telescopic rod of the third electric cylinder is fixedly connected to the bottom mounting seat of the second sliding block.
[0014] Preferably, the support mechanism includes a second motor, which is fixedly connected to the bottom of the mounting frame. A lever sensor is provided on the top of the mounting frame. The bottom output shaft of the second motor is rotatably connected to a drive sprocket. The drive sprocket is connected to a driven sprocket via a transmission chain. The bottom output shaft of the driven sprocket is rotatably connected to a rotating shaft. Both ends of the rotating shaft are connected to second connecting rods, and both second connecting rods are simultaneously connected to the support plate.
[0015] Preferably, a rotating rod is fixedly connected to the top of the garage frame, the rotating rod has a thread inside, a third telescopic rod is rotatably connected inside the rotating rod, a limiting plate is fixedly connected to the telescopic end of the third telescopic rod, a third bracket is fixedly connected to the top of the garage frame, a proximity sensor is rotatably connected to the third bracket, a distance sensor is fixedly connected to the top of the garage frame, and a corresponding distance sensor receiver is installed on the comb frame.
[0016] The beneficial effects of this invention are as follows: With a sliding limiting mechanism, after the vehicle comes to a complete stop, the first motor rotates, driving the bidirectional threaded rod to rotate. The two third sliding blocks, connected to the bidirectional threaded rod, slide towards the center of the second sliding groove, pressing the first baffle to rotate it from a horizontal to a vertical position. Then, the third electric cylinder is activated, and its telescopic rod pulls the second sliding block towards the wheel. The first baffle stops after pressing against the rear wheel, thus positioning the rear wheel. Simultaneously, the front baffle positions the front wheel, ensuring the vehicle's safety within the comb frame.
[0017] The emergency mechanism reduces the risk of the vehicle slipping if the chain at one end of the lifting system suddenly breaks. The extension rod of the second electric cylinder pushes the compression block towards the first connecting rod. The compression block presses the two symmetrically distributed wedge blocks against the first connecting rod, performing an emergency stop. At the same time, the positioning pin is inserted into the hole set in the first connecting rod. The emergency stop also reduces the risk of the positioning pin breaking due to the sudden push of the first electric cylinder in a state of sudden imbalance. The dual emergency treatment can reduce the tilting speed at one end of the comb frame, so that the vehicle will not violently vibrate and slip out of the comb frame in a state of sudden imbalance.
[0018] A rotatable support mechanism is provided. When the vehicle reaches a designated height and moves laterally, the lever sensor is triggered, and the support plate rotates from a vertical state to a horizontal state to support the bottom of the comb frame. At the same time, the positioning pin is inserted into the corresponding hole of the first connecting rod. The double support ensures that the comb frame can exchange more stably with the lateral frame when the lifting system is closed, thus ensuring vehicle safety.
[0019] The garage frame is equipped with proximity and distance sensors at the top to detect the distance between the vehicle and the top when it rises to the fourth level. If the chain becomes loose after prolonged use, the vehicle will not be able to reach the designated height for lateral movement, and the signal will be sent to the back office for professional handling. If the proximity or distance sensor is damaged and the detected values are inconsistent, the signal will also be sent to the back office for emergency handling by professionals. When the lifting system malfunctions, the limit plate extending from the bottom of the rotating rod at the top of the garage frame will limit the vehicle's rising height, the torque protector of the lifting system will disengage, and the lifting system will shut down, ensuring that the vehicle will not be damaged due to continuous rising.

Detailed Implementation
[0031] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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 skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Please see Figure 1-9 As shown, a four-layer chain-type PSH parking equipment includes a garage frame 1, the bottom of which is fixed to the ground. The garage frame 1 is spliced from H-shaped steel beams 2. A comb frame 3 is slidably connected to the garage frame 1. A lifting system 11 is installed at the top of the garage frame 1. The lifting system 11 drives the comb frame 3 to rise and fall along the H-shaped steel beams 2 via a chain. The comb frame 3 includes symmetrically distributed steel frames 4. The inner wall of the steel frame 4 is provided with front comb teeth 5 and rear comb teeth 6 that are fixedly connected. Emergency mechanisms 8 are fixedly connected at both ends of the steel frame 4. A sliding limit mechanism 9 is provided at the top of the steel frame 4.
[0033] The emergency mechanism 8 is equipped with a first sliding block 83 that slides with the H-shaped steel beam 2. The top of the steel frame 4 is equipped with a first sliding groove 10. The limiting mechanism 9 can slide in the first sliding groove 10. An array of first connecting plates 13 are welded between the two opposing H-shaped steel beams 2. An installation frame 15 is connected to the side wall of the first connecting plate 13. A support mechanism 12 is provided in the installation frame 15. The garage frame 1 is equipped with a sliding transverse frame 14 at a specified height. The comb teeth of the transverse frame 14 are arranged alternately with the comb teeth of the comb tooth frame 3.
[0034] The comb frame 3 includes a front baffle 7, which is located at the front end of the front comb 5. When the vehicle drives into the comb frame 3, the front baffle 7 can position the front wheels of the vehicle to prevent the front wheels from falling off the comb frame 3 during lifting and lowering. The limiting mechanism 9 is located on the top of the steel frame 4 near the rear wheels of the vehicle to limit the position of the rear wheels.
[0035] The emergency mechanism 8 includes a first support 81, one side of which is fixedly connected to the outer wall of the steel frame 4, and the other side of which is fixedly connected to a second support 82 and a first sliding block 83. A first connecting rod 21 is welded to the center of the side wall of the H-shaped steel beam 2 near the second support 82. A first electric cylinder 84 is installed on the side wall of the second support 82 near the first support 81. The telescopic rod of the first electric cylinder 84 passes through the second support 82 and connects to the first telescopic rod 87. The telescopic end of the first telescopic rod 87 is fixedly connected to a positioning pin 86. A spring is wound around the outside of the first telescopic rod 87. The first connecting rod 21 has holes corresponding to the positioning pin 86. Several holes are evenly distributed on the first connecting rod 21. At the same time, when the vehicle is parked on the second, third and fourth floors, there are holes at the corresponding positions of the first connecting rod 21 to further ensure the stability when parked.
[0036] The inner wall of the second support 82 is provided with symmetrically distributed second telescopic rods 88. The telescopic ends of the second telescopic rods 88 are fixedly connected to wedge blocks 89. Springs are wound around the outside of the second telescopic rods 88. A second electric cylinder 85 is installed on the outer wall of the second support 82 opposite to the H-shaped steel beam 2. The telescopic rod of the second electric cylinder 85 passes through the second support 82 and is fixedly connected to the compression block 810. When the chain at one end of the parking equipment lifting system 11 suddenly breaks after long-term use, the second electric cylinder 85 starts to push the compression block 810 forward, pressing the two symmetrically distributed wedge blocks 89 onto the first connecting rod 21 for emergency braking. At the same time, the first electric cylinder 84 starts to push the positioning pin 86, which is driven into the hole of the first connecting rod 21 to ensure that the comb frame 3 will not suddenly tilt and cause the vehicle to fall.
[0037] The top of the first sliding block 83 is fixedly connected to the pull ring 831. The first sliding block 83 is equipped with a sliding wheel 832. The bottom chain of the lifting system 11 lifts and lowers the comb frame 3 by pulling the pull ring 831. The comb frame 3 slides along the H-shaped steel beam 2 through the sliding wheel 832.
[0038] The limiting mechanism 9 includes a second sliding block 91. A first motor 92 is installed on one side of the outer wall of the second sliding block 91. The bottom output shaft of the first motor 92 passes through the second sliding block 91 and is rotatably connected to a bidirectional threaded rod 93. A second sliding groove 910 is opened on one side wall of the second sliding block 91. A slidable third sliding block 94 is symmetrically arranged in the second sliding groove 910. The bidirectional threaded rod 93 is rotatably connected to the third sliding block 94. The third sliding block 94 is rotatably connected to a first baffle 95. The two first baffles 95 are simultaneously rotatably connected to the second connecting plate 96.
[0039] The steel frame 4 has an installation cavity 97 inside, and a third electric cylinder 98 is installed in the installation cavity 97. The telescopic rod of the third electric cylinder 98 is fixedly connected to the bottom mounting seat 99 of the second sliding block 91. After the vehicle drives into the comb frame 3, the first motor 92 is started. The rotation of the first motor 92 drives the bidirectional threaded rod 93 to rotate. Both third sliding blocks 94 slide towards the middle, pressing the first baffle 95. When the first baffle 95 rotates to be perpendicular to the third sliding block 94, the third electric cylinder 98 is started. The telescopic rod of the third electric cylinder 98 pulls the second sliding block 91 to slide in the first slide groove 10, and stops after it stops against the rear wheel of the vehicle, reducing the risk of the vehicle falling off.
[0040] The support mechanism 12 includes a second motor 121, which is fixedly connected to the bottom of the mounting frame 15. The top of the mounting frame 15 is equipped with a lever sensor 127. The bottom output shaft of the second motor 121 is rotatably connected to the drive sprocket 122. The drive sprocket 122 is connected to the driven sprocket 123 via a transmission chain. The bottom output shaft of the driven sprocket 123 is rotatably connected to the rotating shaft 124. Both ends of the rotating shaft 124 are connected to second connecting rods 125. Both second connecting rods 125 are simultaneously connected to the support plate 126. When the comb frame 3 slides to a specified height, the lever sensor 127 is triggered, and the second motor 121 starts. The rotation of the second motor 121 drives the drive sprocket 122 to rotate, and the driven sprocket 123, which is connected to the drive sprocket 122, also rotates. At the same time, it drives the rotation of the rotating shaft 124. The second connecting rods 125 connected to the rotating shaft 124 drive the support plate 126 from a vertical state to a horizontal state to support the bottom of the comb frame 3, ensuring the stability of the comb frame 3.
[0041] A rotating rod 16 is fixedly connected to the top of the garage frame 1. The rotating rod 16 has a thread inside. A third telescopic rod 161 is rotatably connected inside the rotating rod 16. A limiting plate 162 is fixedly connected to the telescopic end of the third telescopic rod 161. A third bracket 17 is fixedly connected to the top of the garage frame 1. A proximity sensor 18 is rotatably connected to the third bracket 17. A distance sensor 19 is fixedly connected to the top of the garage frame 1. A corresponding distance sensor 19 receiving end is installed on the comb frame 3. The rotating rod 16 can limit the rising comb frame 3 to a certain extent. When the lifting system 11 is damaged, it prevents the comb frame 3 from rising continuously and causing damage to the vehicle.
[0042] In use, the operator drives the vehicle into the comb frame 3, with the front wheels engaged in the front comb teeth 5 and the rear wheels engaged in the rear comb teeth 6. The front comb teeth 5 have a front baffle 7 at the front end, which positions the front wheels to prevent the vehicle from falling off during lifting and lowering if the front of the vehicle exceeds the comb frame 3. After the vehicle stops, the first motor 92 is started, which rotates and drives the bidirectional threaded rod 93 to rotate. The two third sliding blocks 94, which are rotatably connected to the bidirectional threaded rod 93, slide towards the center of the second sliding groove 910, pressing the first baffle 95 to rotate from a horizontal to a vertical position. Then, the third electric cylinder 98 is started, and the telescopic rod of the third electric cylinder 98 pulls the second sliding block 91 towards the wheel. The first baffle 95 stops after it comes into contact with the rear wheel of the vehicle. The third electric cylinder 98 is then turned off. The first baffle 95 positions the rear wheel of the vehicle, ensuring the safety of the vehicle within the comb frame 3.
[0043] After the vehicle is positioned in the comb frame 3, the lifting system 11 pulls the pull ring 831 via the chain to raise and lower the comb frame 3. A level sensor is installed at the bottom of the comb frame 3. When the chain at one end of the lifting system 11 suddenly breaks, the level sensor becomes unbalanced, and the emergency mechanism 8 at the corresponding end of the comb frame 3 is activated. The telescopic rod of the second electric cylinder 85 pushes the compression block 810 to move towards the first connecting rod 21. The compression block 810 presses the two symmetrically distributed wedge blocks 89 against the first connecting rod 21. The second telescopic rod 88 is stretched to perform an emergency brake and reduce the tilting speed at one end of the comb frame 3.
[0044] At the same time, the telescopic rod of the first electric cylinder 84 pushes the first telescopic rod 87 to move towards the first connecting rod 21, and the positioning pin 86 is inserted into the hole set in the first connecting rod 21. The sliding wheel 832 at one end of the comb frame 3 no longer slides down, and the broken end of the chain no longer tilts down. The risk of slippage is reduced due to the setting of the front baffle 7 and the first baffle 95. At the same time, the emergency braking also reduces the risk of breakage caused by the sudden push of the first electric cylinder 84 in the state of sudden imbalance. After the tilting speed of the comb frame 3 is controlled, it is handled by professionals.
[0045] When the vehicle rises to the designated height, the lifting system 11 is turned off, the lever sensor 127 is triggered, and the second motor 121 is started. The second motor 121 starts to rotate, driving the drive sprocket 122 to rotate. The driven sprocket 123, which is connected to the drive sprocket 122, also rotates, driving the rotation shaft 124 to rotate. The second connecting rod 125, which is connected to the rotation shaft 124, drives the support plate 126 to rotate from a vertical state to a horizontal state, supporting it at the bottom of the comb frame 3. At the same time, the positioning pin 86 is inserted into the corresponding hole set in the first connecting rod 21 to ensure the stability of the comb frame 3. Then the transverse frame 14 moves the vehicle to the corresponding parking space.
[0046] When the vehicle rises to the fourth level, the proximity sensor 18 issues an alarm. The distance measured by the distance sensor 19 is consistent with the value set by the proximity sensor 18. The lifting system 11 is shut down, and the lateral frame 14 moves the vehicle to the corresponding parking space. After long-term use, when the chain becomes loose, the vehicle does not reach the height specified by the fourth level. The distance measured by the distance sensor 19 also exceeds the original value. The vehicle cannot reach the specified height for lateral movement. Professional personnel are notified for handling.
[0047] When the proximity sensor 18 or the distance sensor 19 malfunctions, the proximity sensor 18 will issue an alarm when it reaches the set value, while the distance sensor 19 will issue an alarm when the distance measured is inconsistent with the set value or the proximity sensor 18 has not reached the set value but the distance measured by the distance sensor 19 has reached the set value. The vehicle height cannot be determined, the lifting system 11 will be shut down, and professional personnel will be notified for handling.
[0048] When the lifting system 11 malfunctions and the vehicle's rising height cannot be controlled, when the vehicle reaches the limit plate 162 extending from the bottom of the rotating rod 16, the limit plate 162 can restrict the vehicle from rising continuously. At the same time, the torque protector in the lifting system 11 disengages, the lifting system 11 is shut down, and professional personnel are notified to handle the situation.
