Description

Technical Field

[0001] This invention relates to the field of automated parking equipment technology, specifically a large, manually releasable, circular parking system for cars. Background Technology

[0002] With the rapid development of my country's urban economy and automobile industry, more and more families own private cars. Data shows that in recent years, the average growth rate of urban motor vehicles in my country has been 15%-20%, while the average growth rate of urban parking infrastructure during the same period has been only 2%-3%. In particular, the growth rate of motor vehicle ownership in large cities far exceeds the growth rate of parking infrastructure.

[0003] Vertical circulation parking garages are automated multi-level parking systems suitable for underground garages or public places with limited parking spaces. Controlled by a computer, they vertically lift vehicles to a preset height and then transfer them to their corresponding parking spaces, allowing multiple vehicles to be parked within a single vertical space. During the lifting process, the bottom of the vehicle platform has limited safety features, making vehicles prone to swaying. Furthermore, vertical circulation parking garages require electricity; if the drive mechanism malfunctions or a power outage occurs, the entire garage will be unusable. Some vertical circulation parking garages are equipped with a manual release system, allowing manual vehicle retrieval during power outages. However, retrieving heavier, larger vehicles is labor-intensive and inefficient. Summary of the Invention

[0022] The locking mechanism and manual release mechanism allow for manual vehicle storage and retrieval during power outages. When the parking equipment suddenly loses power, the telescopic electromagnetic lock is de-energized, the first positioning pin returns to its original position along the ball bearings at both ends of the through hole, the spring regains its elasticity, and the torsion spring between the two first rotating rods returns to its initial state, causing the two arc-shaped blocks to engage with the first gear. The two staggered hooks engage, and the vehicle can then be retrieved using the manual release mechanism. The rack is pulled outward from the operating box using the pull rod, and then the first locking block is locked in the slot, fixing the rack's position and unlocking the rack from the second gear.

[0023] Rotating the throttle pulls the wire rope in the first winding reel downwards and winds it onto the second winding reel. When manually rotating the throttle is too strenuous, the lever is pushed outwards, separating the second and third locking blocks and removing the throttle from the sleeve. Then, the second positioning pin is pulled upwards, inserting the external motor shaft into the circular groove. After releasing the second positioning pin, the rectangular block is locked in the groove of the external motor shaft, fixing the external motor shaft to the sleeve. Rotating the external motor can replace manually rotating the throttle, saving labor costs and improving the efficiency of storing and retrieving vehicles. Attached Figure Description

[0055] A contact sensor 414 is fixedly connected to the inner wall of the mounting box 41. When the third support plate 451 touches the contact sensor 414, it indicates that the operator is manually moving the vehicle platform 31. When the contact sensor 414 loses signal, it indicates that the wire rope is broken during use. At this time, the operator needs to be notified for maintenance. A rotatable manual release mechanism 5 is provided on the outer wall of the first support frame 11. The manual release mechanism 5 includes an operation box 51, which is located in the lower half of the first support frame 11.

[0056] The operation box 51 is equipped with a rotatable third rotating shaft 511 and a fourth rotating shaft 512. The third rotating shaft 511 is located below the fourth rotating shaft 512.

The outer wall of the operation box 51 is provided with a third fixing block 536 and a slot 537 that are fixedly connected. The slot 537 is located above the third fixing block 536. When the power is on, the first locking block 535 is locked on the third fixing block 536, and the rack 533 meshes with the second gear 53. When the power is off, the rack 533 can be pulled outward from the operation box 51 by using the pull rod 538. At this time, the first locking block 535 is locked in the slot 537, and the position of the rack 533 is fixed.

[0058] The third rotating shaft 511 extends to the port outside the operation box 51 and is provided with a fixedly connected sleeve 54. The other end of the sleeve 54 is provided with a detachable handle 55. The handle 55 is provided with symmetrically opened sliding grooves 551. The sliding grooves 551 are provided with slidable levers 552. The side wall of the lever 552 is provided with a second locking block 553 that is elastically connected. The outer wall of the sleeve 54 is provided with a third locking block 541 that is fixedly connected. When the lever 552 is pushed outward, the handle 55 is put into the sleeve 54. When the lever 552 is released, the second locking block 553 and the third locking block 541 are locked together, and the position of the handle 55 is fixed.

[0059] The sleeve 54 has a circular groove 542 inside, and the top of the sleeve 54 has a second positioning pin 543 that is elastically connected. The lower end of the second positioning pin 543 has a rectangular block 544 that is fixedly connected. When the power is off, if it is too difficult to manually turn the handle 55, the second positioning pin 543 can be pulled up to insert the external motor shaft into the circular groove 542. Then the second positioning pin 543 is released. At this time, the external motor shaft is fixed to the sleeve 54, which can save labor costs.

[0060] Working principle:

[0061] In use, the driver drives the vehicle into the vehicle-carrying mechanism 3 from the ramp 15 at the entrance. After the front wheels encounter the front baffle 312, the driver stops and leaves. At this time, the second motor 34 is started. The rotation of the second motor 34 drives the rotating block 33 to rotate, and the third link 331 also moves accordingly, causing the second rotating seat 332 to slide towards the rotating block 33. The sliding of the second rotating seat 332 causes the fourth link 333 to rotate, and the fourth connecting column 337 also rotates accordingly, causing the first fixed block 335 to rotate. The symmetrically distributed fifth connecting columns 336 can be used to position the tires, reducing the risk of the car falling during the lifting and lowering cycle.

[0062] After the vehicle is positioned, the first motor 13 is started. The first motor 13 and the first rotating shaft 2 are driven by a sprocket. The rotation of the first motor 13 drives the first rotating shaft 2 to rotate. At the same time, the drive wheel 21 also rotates, which drives the first chain 23 to rotate. The triangular plate 24 also moves, which drives the first connecting column 321 to move. The vehicle carrying mechanism 3 also moves along the second guide rail 14.

[0063] When the parking equipment suddenly loses power, the telescopic electromagnetic lock 412 is de-energized, the first positioning pin 413 returns to its original position along the ball bearings at both ends of the through hole 429, the spring 426 regains its elasticity, the torsion spring between the two first rotating rods 423 returns to its initial state, and drives the inner tooth blocks of the two arc-shaped blocks 424 to engage with the first gear 44, and the two staggered hooks 428 engage. At this time, the vehicle can be stored and retrieved using the manual release mechanism 5. The rack 533 is pulled outward from the operating box 51 using the pull rod 538, and then the first locking block 535 is locked in the slot 537, the position of the rack 533 is fixed, and the rack 533 is unlocked from the second gear 53.

[0064] Rotating the throttle 55 pulls the wire rope in the first take-up reel 43 downwards and winds it onto the second take-up reel 521. The wire rope in the first take-up reel 43 passes through the first groove 452 in the second support plate 45 and the third support plate 451. The friction between the third magnet 453 and the wire rope causes the third support plate 451 to rotate outwards from the mounting box 41. When the third support plate 451 touches the contact sensor 414, the contact sensor 414 sends a signal, the disc 42 rotates, driving the first gear 44 to rotate, the shaft of the first motor 13 rotates, and the first rotating shaft 2 also rotates, causing the vehicle carrier mechanism 3 to move.

[0065] When the wire rope breaks during use, the friction between the third magnet 453 and the wire rope disappears, the third support plate 451 returns to its initial state, and the contact sensor 414 loses its signal. At this time, the operator needs to perform maintenance. It can be used to detect the connection status of the wire rope. When it is difficult to manually turn the handle 55, the lever 552 is pushed outward, the second locking block 553 and the third locking block 541 are separated, the handle 55 is removed from the sleeve 54, and then the second positioning pin 543 is pulled upward. After inserting the external motor shaft into the circular groove 542, the second positioning pin 543 is released. At this time, the rectangular block 544 is locked in the groove of the external motor shaft, and the external motor shaft is fixed to the sleeve 54. The rotation of the external motor can replace the manual rotation of the handle 55, which can save labor costs and improve the efficiency of storing and retrieving vehicles.
