Description

Technical Field

[0001] This invention relates to the field of automated parking systems, and in particular to a lifting device for automated parking systems with balance adjustment. Background Technology

[0002] Automated parking garages primarily use gondolas (or simply gondolas) to transfer cars parked on the ground floor to the floor where their designated parking spaces are located. The gondolas are equipped with lateral moving trolleys to facilitate the movement of the car to the corresponding space. These trolleys typically feature extendable and retractable grab arms to support the car's tires.

[0003] The general process of grabbing a car in a multi-level parking garage is as follows: when a vehicle is parked in one of the parking spaces, the car lowers, the trolley moves to the corresponding position, the grabbing mechanism extends forward to grab the vehicle and then retracts into the trolley. There are two operating modes: the first is that the trolley moves to the middle position of the car, the car rises to the vehicle placement level, and then the trolley moves laterally to the corresponding parking space after reaching the placement level; the second is that after the grabbing mechanism retracts, the car and the trolley move simultaneously, the car rises to the placement level, and the trolley moves laterally to align with the corresponding parking space.

[0004] In the first method, when the car rises, the trolley is in the middle position, so the car is in a balanced state. However, since the movement must follow this logical sequence, each step requires waiting for the sensor to confirm that it is in place before proceeding to the next movement step, which takes a long time.

[0005] The second method uses linear interpolation to move directly to the destination parking space, which takes less time. However, during the lifting process, the trolley is always in a lateral movement state. Therefore, the balance of the car is constantly changing. When the lateral movement vehicle is not in the middle position, the car will be unbalanced and tilt, making it impossible to lift and lower stably. In severe cases, the car may slip.

[0006] To improve transfer efficiency and safety, under the premise of adopting the second method, it is necessary to improve the car level tilt caused by the center offset. Summary of the Invention

[0007] This invention provides a three-dimensional parking garage lifting device with balance adjustment, which solves the problem of car tilting caused by center offset during car grabbing and transportation.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a three-dimensional parking garage lifting device with balance adjustment, including a car that moves up and down along a vertical guide rail. The car has a rectangular frame structure. At least four corners of the car are provided with pull cables for suspending the car. The pull cables include at least two first pull cables and at least two second pull cables. The first pull cables and second pull cables are respectively located at both ends of the length direction of the car. A trolley carriage that can slide along the length direction of the car is provided on the car. The device also includes a first tensioner. The first tensioner is provided with a rotatable rotating sleeve. Each end of the rotating sleeve is provided with a first pull rope locking terminal. The two ends of the first pull cables are respectively connected to one end of the car and the first pull rope locking terminal. The rotating sleeve rotates to raise or lower one end of the car.

[0009] Laser rangefinders are installed on the ground or at both ends of the lower end of the car to detect the real-time height of the four corners of the car, providing numerical data for leveling the car.

[0010] In a preferred embodiment, the first tensioner further includes a geared motor and a rotatable sector gear. The sector gear and the rotating sleeve are connected as a unit via a connecting shaft. The shaft end of the geared motor is provided with a drive gear, which meshes with the sector gear.

[0011] In a preferred embodiment, the system further includes a counterweight device, a first top beam, and a second top beam. A first tensioner is located in the middle of the first top beam. The counterweight device has third rotating wheels at both ends of its upper end. The first top beam has a fourth rotating wheel and a fifth rotating wheel at both ends. The second top beam has a seventh rotating wheel, a second rope locking terminal, and a third rope locking terminal at both ends. The car has a first rotating wheel and a second rotating wheel at each end. One end of the first pull cable is connected to the first rope locking terminal, and the other end passes sequentially around the fourth rotating wheel, the first rotating wheel, the fifth rotating wheel, the seventh rotating wheel, and the third rotating wheel to connect to the second rope locking terminal. One end of the second cable is connected to the third cable locking terminal, and the other end passes sequentially around the second rotating wheel, the seventh rotating wheel, and the third rotating wheel to connect to the second cable locking terminal.

[0012] In the preferred embodiment, a drive shaft and a power motor are also provided. The seventh rotating wheel is located at both ends of the drive shaft, and the power motor drives the seventh rotating wheel to rotate through the drive shaft.

[0013] In a preferred embodiment, an eighth rotating wheel is provided at the lower end of the seventh rotating wheel. One end of the second pull cable is connected to the third pull rope locking terminal, and the other end passes around the second rotating wheel, the eighth rotating wheel, the seventh rotating wheel and the third rotating wheel in sequence to connect to the second pull rope locking terminal.

[0014] In a preferred embodiment, a sixth rotating wheel is provided on the side of the seventh rotating wheel near the fifth rotating wheel. One end of the first pull cable is connected to the first pull rope locking terminal, and the other end passes sequentially around the fourth rotating wheel, the first rotating wheel, the fifth rotating wheel, the sixth rotating wheel, the seventh rotating wheel, and the third rotating wheel to connect to the second pull rope locking terminal.

[0015] In a preferred embodiment, a second tensioner and a third tensioner are also included. The second and third tensioners have the same structure as the first tensioner. The second tensioner is located between the fourth rotating wheel and the first tensioner and breaks the first pull cable. The pull cable locking terminals at both ends of the second tensioner are connected to the broken first pull cable. The third tensioner is located between the second pull cable locking terminal and the third rotating wheel and breaks the second pull cable. The pull cable locking terminals at both ends of the third tensioner are connected to the broken second pull cable.

[0016] In the preferred embodiment, the outer side of the rotating sleeve is provided with multiple protruding ears, and a pin is provided on the protruding ears. One end of the first pull rope locking terminal is hinged to the protruding ear through the pin.

[0017] In the preferred embodiment, the pin is inserted into the protruding lug, and a retaining pin is provided at the end of the pin.

[0018] In the preferred embodiment, the outer wall of the connecting shaft is provided with multiple retaining keys along the circumferential direction, and the retaining keys engage with the rotating sleeve.

[0019] The beneficial effects of this invention are as follows: By using a tensioner to wind up the cable at a certain angle and changing the height of one end of the car, the length of the car remains horizontal during the lateral movement of the trolley during the lifting process without affecting the transfer efficiency, preventing one end from tilting down; by adjusting the cable length to change the height of one end of the car, the load-bearing frame structure of the lifting device does not move, making the adjustment safer and more reliable; by using pulleys instead of conventional fixed lifting points, and through a special rope winding method, the two ends of the car can be balanced by a single counterweight; in the preferred embodiment, the lengths of all three cables can be adjusted, and the height of the car in the front-to-back and left-to-right directions can be changed, ensuring good car levelness during the lateral movement of the trolley and when grabbing the car, making it safer and more reliable.

Detailed Implementation

[0033] like Figure 1-11 In this invention, a lifting device for a three-dimensional parking garage with balance adjustment includes a car 1 that moves up and down along a vertical guide rail 7. The car 1 has a rectangular frame structure. At least four corners of the car 1 are provided with pull cables for suspending the car 1. The pull cables include at least two first pull cables and at least two second pull cables. The first pull cables and second pull cables are located at both ends of the length direction of the car 1, respectively. A trolley 6 that can slide along the length direction of the car 1 is provided on the car 1. The device also includes a first tensioner 3. The first tensioner 3 is provided with a rotatable rotating sleeve 302. Each end of the rotating sleeve 302 is provided with a first pull rope locking terminal 301. The two ends of the first pull cable are respectively connected to one end of the car 1 and the first pull rope locking terminal 301. The rotating sleeve 302 rotates to raise or lower one end of the car 1.

[0034] The car 1 is welded from profiles and plates into a whole. The upper surface of the car 1 is provided with a track, and the middle carriage 6 slides on the track. A synchronous belt device 10 is also provided. The synchronous belt device 10 includes a drive motor, a ring-shaped synchronous belt, a synchronous pulley, and a synchronous belt clamping component. The synchronous belt clamping component connects the synchronous belt to the bottom of the middle carriage 6. The drive motor drives the synchronous belt to move through the synchronous pulley. Vertical guide rails 7 are installed on the support frame or building body. There are at least four vertical guide rails 7 located at the four corners of the car 1. The four corners of the car 1 are provided with orthogonal guide wheels that can roll against the two vertical sides of the vertical guide rails 7.

[0035] The medium-sized vehicle 6 is used to install a grabber device that can extend and retract.

[0036] Laser rangefinders are installed on the ground or at both ends of the lower end of the car 1 to detect the real-time height of the four corners of the car 1, providing numerical data for leveling the car 1.

[0037] In a preferred embodiment, the first tensioner 3 further includes a reduction motor 305 and a rotatable sector gear 303. The sector gear 303 and the rotating sleeve 302 are connected as a whole through a connecting shaft 309. The shaft end of the reduction motor 305 is provided with a drive gear 304, which meshes with the sector gear 303.

[0038] Initially, the drive gear 304 is located at the center of the outer end gear surface of the sector gear 303. The rotating sleeve 302 rotates through a certain angle, retracting part of the first cables on both sides, so that the first cables on both sides are at a certain angle. When this end is too high, the sector gear 303 is adjusted to make the first cables on both sides closer to parallel. Since the shortest distance between two points is a straight line, the end of the car 1 connected to the first tensioner 3 descends. If this end is too low, the sector gear 303 is adjusted in the opposite direction to pull the first cables at both ends more towards the middle, making the included angle more obvious, and the end of the car 1 then rises.

[0039] In a preferred embodiment, the system further includes a counterweight device 2, a first top beam 4, and a second top beam 5. A first tensioner 3 is located in the middle of the first top beam 4. The counterweight device 2 has a third rotating wheel 201 at both ends of its upper end. The first top beam 4 has a fourth rotating wheel 401 and a fifth rotating wheel 402 at both ends. The second top beam 5 has a seventh rotating wheel 502, a second rope locking terminal 504, and a third rope locking terminal 505 at both ends. The car 1 has a first rotating wheel 101 and a second rotating wheel 102 at each end. One end of the first cable is connected to the first rope locking terminal 301, and the other end passes sequentially around the fourth rotating wheel 401, the first rotating wheel 101, the fifth rotating wheel 402, the seventh rotating wheel 502, and the third rotating wheel 201 to connect with the second rope locking terminal 504. One end of the second cable is connected to the third cable locking terminal 505, and the other end passes sequentially around the second rotating wheel 102, the seventh rotating wheel 502 and the third rotating wheel 201 to connect to the second cable locking terminal 504.

[0040] Each wheel is a multi-grooved wheel, which can arrange multiple pull cables at the same time. Both the first and second pull cables are multiple.

[0041] In a preferred embodiment, a drive shaft 506 and a power motor 507 are also provided. The seventh rotating wheel 502 is located at both ends of the drive shaft 506, and the power motor 507 drives the seventh rotating wheel 502 to rotate through the drive shaft 506.

[0042] One end of the drive shaft 506 is connected to the seventh rotating wheel 502 via a universal joint, reducing the requirement for the coaxiality of the two seventh rotating wheels 502.

[0043] In a preferred embodiment, an eighth rotating wheel 503 is also provided at the lower end of the seventh rotating wheel 502. One end of the second pull cable is connected to the third pull rope locking terminal 505, and the other end passes through the second rotating wheel 102, the eighth rotating wheel 503, the seventh rotating wheel 502 and the third rotating wheel 201 in sequence to connect with the second pull rope locking terminal 504.

[0044] In a preferred embodiment, a sixth rotating wheel 501 is provided on the side of the seventh rotating wheel 502 near the fifth rotating wheel 402. One end of the first pull cable is connected to the first pull rope locking terminal 301, and the other end passes sequentially around the fourth rotating wheel 401, the first rotating wheel 101, the fifth rotating wheel 402, the sixth rotating wheel 501, the seventh rotating wheel 502 and the third rotating wheel 201 to connect with the second pull rope locking terminal 504.

[0045] The main functions of the sixth rotating wheel 501 and the eighth rotating wheel 503 are to change the direction of the cable pulling to avoid interference, and at the same time increase the wrap angle of the cable pulling.

[0046] In a preferred embodiment, the device further includes a second tensioner 8 and a third tensioner 9. The second tensioner 8 and the third tensioner 9 have the same structure as the first tensioner 3. The second tensioner 8 is located between the fourth rotating wheel 401 and the first tensioner 3 and breaks the first pull cable. The pull cable locking terminals at both ends of the second tensioner 8 are connected to the broken first pull cable. The third tensioner 9 is located between the second pull cable locking terminal 504 and the third rotating wheel 201 and breaks the second pull cable. The pull cable locking terminals at both ends of the third tensioner 9 are connected to the broken second pull cable.

[0047] One of the two first pull cables is equipped with a second tensioner 8 on the front side, and one of the two second pull cables is equipped with a third tensioner 9 on the front side. The front side refers to the side where the middle carriage enters and exits when grabbing the car. At this time, among the four pull cables, only the length of the second pull cable closest to the rear is not adjustable, while the length of both first pull cables can be uniformly adjusted by winding up the first tensioner 3. In addition, the length of the first pull cable on the front side can be adjusted again by winding up the second tensioner 8. Among the two second pull cables, the length of the second pull cable on the front side can be adjusted by winding up the third tensioner 9. Therefore, three of the four corners of the car 1 can be pulled up or lowered.

[0048] During initial debugging, adjust the sector gears of the three tensioners so that the drive gear is in the center, i.e., the tensioners are pre-wound at a certain angle. After adjusting the car 1 to a horizontal state, lock the rope locking terminal. When the grabbing mechanism extends to grab the car, the grabbing arm extends from the middle carriage 6 to lift the car, and the overall center of gravity of the car shifts to the front. At this time, the second tensioner 8 and the third tensioner 9 are wound up, so that the front is slightly lifted. As the grabbing device retracts, the car is pulled back into the middle carriage 6, and the center of gravity gradually returns to normal. During this process, the second tensioner 8 and the third tensioner 9 are continuously adjusted to keep the car 1 horizontal at all times.

[0049] In the preferred embodiment, the outer side of the rotating sleeve 302 is provided with multiple protruding ears, and a pin 306 is provided on the protruding ears. One end of the first pull rope locking terminal 301 is hinged to the protruding ear through the pin 306.

[0050] In the preferred embodiment, the pin 306 is inserted into the protruding ear, and the end of the pin 306 is provided with a retaining pin 307.

[0051] In the preferred embodiment, the outer wall of the connecting shaft 309 is provided with a plurality of locking keys 308 along the circumferential direction, and the locking keys 308 are engaged with the rotating sleeve 302.

[0052] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
