Description

Technical Field

[0001] This invention relates to the field of automated parking technology, and particularly to a pit-type, two-level lifting and traversing parking system. Background Technology

[0002] With the continuous increase in urban population, traffic congestion and parking shortages in cities are becoming increasingly serious problems. This situation has negatively impacted traffic flow and the quality of urban life. Traditional surface parking lots can no longer meet the ever-increasing number of vehicles. Parking issues are becoming increasingly prominent in the fields of urban traffic management and parking facilities, with the shortage of urban parking spaces, congestion, and environmental pollution attracting widespread attention. Traditional parking facilities, such as underground and surface parking lots, while efficient to some extent, suffer from problems such as large space occupation, low operational efficiency, significant environmental impact, and insufficient safety. These problems urgently require innovative solutions. The development of liftable parking facilities has emerged as a potential way to solve urban parking problems because they can effectively utilize limited land space and increase parking capacity and efficiency. Existing technologies have significant problems in terms of space efficiency, operational efficiency, environmental friendliness, and safety. Traditional parking facilities occupy a large amount of ground area, require time and labor for manual operation, easily lead to traffic congestion, and also pose environmental problems and vehicle safety hazards.

[0003] For example, a simple lifting and jacking parking device with patent publication number CN 110700657 A discloses "a frame, a car platform vertically lifted and mounted on the frame, a support arm driven by a power device below the car platform, a tie rod between the car platform and the support arm, a hook hinged to the car platform via a first pivot, a pin adapted to the hook on the support arm, a pull plate fixedly mounted on the first pivot, a tension spring between the pull plate and the car platform, a handle hinged to the car platform via a second pivot, a pull cable between the handle and the pull plate, the handle including a mounting end hinged to the car platform and a free end for easy operation, and a hook..." When disengaged from the pin, the free end is located below the vehicle-carrying platform. This invention solves the technical problems of unreliable safety performance and inconvenience in use of current simple lifting and lowering parking systems, and is widely used in multi-level parking garages. While the above structure can lift and lower vehicles, it is relatively bulky, and after the vehicle is raised, the space at the bottom is occupied by numerous mechanical parts, making it difficult to effectively park vehicles below to make reasonable use of space. Furthermore, after parking a vehicle below, retrieving a vehicle above requires moving the vehicle below, which is extremely inconvenient. In addition, many parking lots consist of two-story parking systems above ground, resulting in low space utilization. To better utilize parking space, we need a multi-level parking system that can accommodate three stories. In addition, conventional liftable parking equipment often requires shock absorption devices when in use, because the vehicle platform needs to be cushioned and damped when it is raised or lowered to park the vehicle. Existing vehicle platform shock absorption devices or other similar shock absorption devices are mostly simple shock-absorbing pads or shock-absorbing springs, which have poor cushioning and shock absorption effects when in use, and the vehicle platform is prone to large vertical fluctuations when raised or lowered.

[0004] To address the aforementioned issues, we provide a pit-type, two-level, lift-and-slide parking system that allows parking on two levels above ground and on one level below ground. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pit-type, two-story lifting and traversing parking device.

[0006] The objective of this invention is achieved as follows: a pit-type, two-level lifting and lateral sliding parking device includes a support frame with three parking platforms on it. Each parking platform includes multiple horizontally distributed vehicle-carrying plates. The lowest parking platform is below ground level, the highest parking platform is above ground level, and the middle parking platform is flush with the ground. The vehicle-carrying plates in the lowest and highest parking platforms can move vertically, while the vehicle-carrying plates in the middle platform can move horizontally. When the upper or lower vehicle-carrying plates need to load or unload vehicles, the middle vehicle-carrying plates are moved laterally, freeing up the space corresponding to the vehicle-carrying plate that needs to be moved up or down, facilitating the lower or higher vehicle-carrying plates to move up or down to a position flush with the ground.

[0007] Furthermore, a middle crossbeam support is provided in the middle of the support frame, and the parking platform of the middle layer is located on the middle crossbeam support.

[0008] Furthermore, a top crossbeam support is provided on the upper part of the support frame, and the top parking platform is located on the top crossbeam support.

[0009] Furthermore, rails are provided on the front and rear sides between the intermediate crossbeams, and multiple vehicle-carrying plates are provided on the parking platform of the middle layer. The front and rear ends of the vehicle-carrying plates move left and right along the rails to facilitate moving the vehicle-carrying plates that need to be moved up or down to a position flush with the ground.

[0010] Furthermore, each of the vehicle carrier plates is equipped with a drive motor at its bottom, which drives the vehicle carrier plate to move laterally along the guide rail.

[0011] Furthermore, the vehicle platform is equipped with a transmission rod that can rotate on both the left and right sides. Rollers are fixed at both ends of the transmission rod, and the rollers are located on the track. The drive motor drives the transmission rod to rotate.

[0012] Furthermore, lifting motors are installed on the middle crossbeam support and the top crossbeam support above the vehicle carrier plate two and vehicle carrier plate three on the top parking platform and the bottom parking platform, and the vehicle carrier plate two and vehicle carrier plate three are lifted and lowered by driving motors.

[0013] Furthermore, rotating rods are respectively installed on the support frame below the middle crossbeam support and the top crossbeam support.

The lower end of the chain is fixedly connected to the rear end of the vehicle platform, and the front end of chain two is fixedly connected to the front end of the vehicle platform. The vehicle platform moves up and down through chains one and two. The rear ends of chains one and two pass around gears two and three respectively. A counterweight is fixedly connected to the rear ends of chains one and two. The counterweight hangs vertically downward.

[0014] A shock-absorbing pad mechanism is installed on the ground below the vehicle platform to mitigate the inertia when the vehicle platform falls.

[0015] The shock-absorbing pad mechanism includes a base plate, with pads provided on the front and rear sides of the upper part of the base plate. A buffer mechanism is provided in the middle of the base plate that can move up and down. The buffer mechanism includes a buffer wheel that can move up and down on the base plate.

[0016] Furthermore, the buffer mechanism also includes a lifting block that can move up and down, with buffer wheels mounted on the lifting block.

[0017] Furthermore, a lifting groove is provided on the base plate, and the lifting block is located in the lifting groove and can move up and down.

[0018] Furthermore, the lower part of both the left and right sides of the lifting groove is provided with a slider groove, and the lifting block is provided with sliders on both the left and right sides, and the sliders are located in the slider grooves and can move up and down.

[0019] Furthermore, the slider and the lifting block are rotatably connected, and a rotating shaft is provided between the slider and the lifting block. The slider and the lifting block are rotatably connected through the rotating shaft, and the lifting block is located in the lifting groove and can rotate around the rotating shaft. Springs are respectively provided at the lower ends of the two sliders, and the bottom of the springs is connected to the bottom of the slider groove.

[0020] Furthermore, a spring groove is provided at the bottom of the lifting groove, and a spring is provided in the spring groove. The upper end of the spring is fixedly connected to the bottom of the lifting block, and the lower end of the spring is connected to the bottom of the spring groove.

[0021] Furthermore, there are two buffer wheels, symmetrically distributed on the front and rear sides of the lifting block. The two buffer wheels are connected to the lifting block by support rods. The upper end of the support rod is rotatably connected to the buffer wheel, and the lower end of the support rod is rotatably connected to the lifting block. An elastic mechanism is provided between the two support rods. The elastic mechanism includes a double-ended screw, a rotating block is provided in the middle of the double-ended screw, and nuts are threaded through both ends of the double-ended screw. The threads at both ends of the double-ended screw rotate in opposite directions. A rotating seat is rotatably provided inside the support rod, and a spring is provided between the rotating seat and the nut.

[0022] Furthermore, the upper part of the base plate is provided with a limiting wheel that can move left and right, and a transmission plate is provided between the limiting wheel and the base plate. The base is provided with left and right transmission plate slots, the transmission plate is rotatably located in the transmission plate slots, the limiting wheel is rotatably located at the upper part of the transmission plate, the transmission plate has an L-shaped obtuse angle structure, and the upper part of the transmission plate can rotate relative to the base.

[0023] Furthermore, a guide seat is provided on the outer side of the bottom of the transmission plate.

[0024] Furthermore, an extrusion block is fixedly connected to the outer side of the inner slider. The lower surface of the extrusion block has a sloping structure. The bottom of the transmission plate is located below the extrusion block. An arc-shaped groove is provided on the outer side of the extrusion block. A locking rod is rotatably provided at the bottom of the transmission plate.

[0025] In use, this invention employs a controller to control the start and stop of the entire device. The controller can be any existing technology capable of performing the following functions. The movement method of each vehicle carrier is unique to this device. When a vehicle needs to be parked on the upper vehicle carrier (secondary), the drive motor on the middle parking platform (firstary) moves the vehicle carrier (firstary) laterally, creating space on the parking platform below the vehicle carrier (secondary) to facilitate its descent. Then, the lifting motor corresponding to the lowering vehicle carrier (secondary) is rotated. The lifting motor, via chain four, drives gear one to rotate. A drive gear is fixedly installed at the output end of the lifting motor, and chain four connects the drive gear and gear one. This, in turn, drives a rotating rod to rotate. The rotating rod then drives gears two and three to rotate, which in turn moves chains one and two connected to the vehicle carrier (secondary). When chains one and two are lowered, the vehicle carrier falls, and the counterweight connected to the rear end moves upward. (A gear five is located in the middle of chain one on the second vehicle platform. Gear five is rotatably mounted on the top crossbeam support. Chain one passes over gear five from above and connects to the rear end of the second vehicle platform. A gear four is located in the middle of chain two on the second vehicle platform. Gear four is rotatably mounted on the top crossbeam support. Chain two passes over gear four from above and connects to the front end of the second vehicle platform.) Until the second vehicle platform is level with the ground, move the vehicle onto the second vehicle platform. Then, control its corresponding lifting motor to reverse, causing the second vehicle platform to move upwards and the counterweight to move downwards. This prevents chain two from disengaging from chain one and gear two and gear three, and also prevents the chain from swinging. When it is necessary to lower the vehicle platform from the parking platform above to unload the vehicle, the same steps can be used.

[0026] When a vehicle needs to be parked on the bottom vehicle platform three, the corresponding vehicle platform one on the middle parking platform above it is also moved horizontally to make room for the corresponding vehicle platform three below to move upward; the lifting motor is controlled by the controller to rotate, which drives the chain one and chain two connected to the vehicle platform three to move. When the chain one and chain two are retracted, the vehicle platform moves upward and the counterweight block connected to the rear moves downward. (The bottom of chain one on vehicle carrier plate three is connected to the rear end of vehicle carrier plate three; gears six, seven, and eight are set in the middle of chain two on vehicle carrier plate three. Gears six, seven, and eight are rotatably mounted on the support frame. Chain two passes over gears six and seven from below, and then passes over gear eight from above, connecting to the front end of vehicle carrier plate three;) until vehicle carrier plate three is moved to a position level with the ground, move the vehicle onto vehicle carrier plate three, and then control its corresponding lifting motor to reverse, driving vehicle carrier plate three to move downwards and the counterweight to move upwards, preventing chain two from disengaging from gears two and three, and also preventing the chain from swinging. When it is necessary to lift the vehicle from the vehicle carrier plate on the parking platform below, the above steps can also be used to unload the vehicle.

[0027] Vehicles can also be parked on the vehicle platform in the middle position to make reasonable use of space and park more vehicles; and when the lowest vehicle platform is in direct contact with the ground, a shock-absorbing pad mechanism is installed to buffer the falling speed of the vehicle platform to avoid damage to the ground or vehicle platform caused by direct hard contact with the ground when the vehicle platform falls. The shock-absorbing pad mechanism is placed below the vehicle platform. When the vehicle platform moves downwards, it first contacts the buffer wheels. If the bottom of the vehicle platform is uneven, it will first contact one buffer wheel. As the vehicle platform continues to press down, the lifting block rotates around the pivot, causing the buffer wheel on the other side to contact and adhere to the bottom of the vehicle platform. The two buffer wheels are distributed on both sides of the pivot, thus enabling the lifting block to rotate and ensure that both buffer wheels contact the ground when the vehicle platform moves downwards. After the two buffer wheels contact the ground, the support rod rotates downwards, spring two is stretched, and spring four is compressed. The buffer wheels provide an upward elastic force to the vehicle platform, achieving cushioning. As the vehicle platform continues to move downwards, the elastic force from springs two and four increases, further achieving the cushioning effect of the vehicle platform's downward movement. This continues until the upper surface of the buffer wheel and the upper surface of the pad are on the same plane. The pad is made of elastic rubber material and is used to support the vehicle platform, preventing hard collisions and achieving two-stage cushioning. When the vehicle platform's compression buffer rollers move downwards, the two buffer rollers open outwards, causing them to rotate upon contact with the vehicle platform and expand outwards, thus preventing scratches on the lower surface of the vehicle platform. As the vehicle platform moves downwards, the lifting block moves downwards, and the compression block's inclined surface presses against the lower part of the transmission plate, causing the compression plate to rotate around the guide seat. The guide seat has an L-shaped obtuse angle structure. During rotation, the limiting roller above the guide seat moves inwards, allowing it to move towards the side of the vehicle platform until the side of the vehicle platform contacts the limiting roller. When the compression block continues to move downwards, the limiting roller can no longer move towards the vehicle platform. At this point, the transmission plate moves outwards, the guide seat moves outwards, and the spring is compressed. When the vehicle platform stops falling, the locking rod engages with the arc-shaped groove. The above implementation can be achieved through the selection of matching component dimensions, which is existing technology and will not be described in detail.

[0028] As the vehicle platform moves upward, the limiting wheel remains in contact with the side of the vehicle platform until it disengages from the buffer wheel. When the vehicle platform disengages from the buffer wheel, the lifting block moves upward under the action of the two springs, causing the pressing block to move upward, just enough to disengage the locking rod from the arc-shaped slot. This technical solution can achieve the above function through the elastic force of the spring, which is existing technology and will not be elaborated further. The vehicle platform continues to move upward, disengaging from the limiting wheel, and the limiting wheel resets.

[0029] Rotating the rotating block adjusts the distance between the nuts on both sides and the center of the double-ended screw, thereby adjusting the distance between the two buffer wheels when no external force is applied. The smaller the distance, the greater the buffering reaction force on the object. Furthermore, the opposite threads of the double-ended screw ensure that the distance between the outer ends of the two springs and the center of the double-ended screw can be adjusted simultaneously. The presence of a spring ensures that the two buffer wheels always face upwards when the platform is moved upwards.

[0030] Beneficial effects: This device can park vehicles on two levels of vehicle platforms above ground, as well as on a vehicle platform on the first basement level. It effectively utilizes parking space, requiring only a gap of one vehicle platform in the central parking platform to accommodate vehicles on three levels. It is equipped with shock-absorbing pads to cushion the vehicle platforms, and limit wheels to restrict the sides of the vehicle platforms, preventing excessive lateral swaying. The limit wheels also automatically press and fit the sides of the falling vehicle platforms, making it more convenient to use. Furthermore, the two buffer wheels can adapt to vehicle platforms with different bottom surfaces. Attached Figure Description

[0064] When using this invention, the start and stop of the entire device is controlled by a controller. The controller can be any existing technology that can achieve the following functions. The movement method of each vehicle carrier is unique to this device. When a vehicle needs to be parked on the upper vehicle carrier 4, the vehicle carrier 5 on the middle parking platform is controlled by the drive motor 23 to move the vehicle carrier 5 laterally, so that a space is made on the parking platform below the vehicle carrier 4 that needs to be lowered, so as to facilitate the lowering of the vehicle carrier. Then, by controlling the lifting motor 9 corresponding to the vehicle platform 2 4 that needs to be lowered, the lifting motor 9 rotates through the chain 4 10, which drives the gear 1 15 to rotate. The output end of the lifting motor 9 is fixedly equipped with a drive gear, and the chain 4 10 is set between the drive gear and the gear 1 15. This drives the rotating rod 14 to rotate. When the rotating rod 14 rotates, it drives the gear 2 16 and the gear 3 17 to rotate, which in turn drives the chain 1 11 and the chain 2 13 connected on the vehicle platform 2 4 to move. When the chain 1 11 and the chain 2 13 are lowered, the vehicle platform falls, and the counterweight block 18 connected at the rear end moves upward. (A gear 12 is installed in the middle of chain 11 on the second vehicle platform 4. Gear 12 is rotatably mounted on the top crossbeam bracket 3. Chain 11 passes over gear 12 from above and connects to the rear end of the second vehicle platform 4. A gear 19 is installed in the middle of chain 213 on the second vehicle platform 4. Gear 19 is rotatably mounted on the top crossbeam bracket 3. Chain 213 passes over gear 19 from above and connects to the front end of the second vehicle platform 4.) Until the second vehicle platform 4 falls to a position level with the ground, the vehicle is moved onto the second vehicle platform 4. Then, the corresponding lifting motor 9 is reversed to move the second vehicle platform 4 upwards and the counterweight 18 downwards, preventing chain 213 from disengaging from chain 11 from gears 216 and 317, and also preventing chain swaying. When it is necessary to lower the vehicle platform from the parking platform above to unload the vehicle, the above steps can also be used to unload the vehicle.

[0065] When a vehicle needs to be parked on the bottom vehicle platform 36, the corresponding vehicle platform 5 on the middle parking platform above it is also moved horizontally to make room for the vehicle platform 36 below to move upward. The lifting motor 9 is controlled by the controller to rotate, which drives the chain 11 and chain 2 13 connected to the vehicle platform 36 to move. When the chain 11 and chain 2 13 are retracted, the vehicle platform moves upward and the counterweight block 18 connected to the rear moves downward. (The bottom of chain 11 on vehicle platform 36 is connected to the rear end of vehicle platform 36; gears 6, 7, and 8 are provided in the middle of chain 213 on vehicle platform 36. Gears 6, 7, and 8 are rotatably mounted on support frame 2. Chain 213 passes over gears 6 and 7 from below, and then passes over gear 8 from above to connect with the front end of vehicle platform 36;) Until vehicle platform 36 is raised to a position level with the ground, the vehicle is moved onto vehicle platform 36, and then the corresponding lifting motor 9 is controlled to reverse, driving vehicle platform 36 to move downwards and counterweight 18 to move upwards, preventing chain 213 from disengaging from chain 3 and gears 216 and 317, and also preventing the chain from swinging. When it is necessary to lift the vehicle from the vehicle platform on the parking platform below, the above steps can also be used to unload the vehicle.

[0066] Vehicles can also be parked on the vehicle platform in the middle position to make reasonable use of space and park more vehicles; and when the lowest vehicle platform is in direct contact with the ground, a shock-absorbing pad mechanism 8 is set to buffer the falling speed of the vehicle platform to avoid damage to the ground or vehicle platform caused by direct hard contact with the ground when the vehicle platform falls. The shock-absorbing pad mechanism 8 is placed below the vehicle platform. When the vehicle platform moves downward, it first contacts the buffer wheel 808. If the bottom of the vehicle platform is uneven, it will first contact one buffer wheel 808. As the vehicle platform continues to press down, the lifting block 806 rotates around the pivot, so that the buffer wheel 808 on the other side contacts and adheres to the bottom of the vehicle platform. The two buffer wheels 808 are distributed on both sides of the pivot, so that the lifting block 806 can rotate when the vehicle platform moves downward, allowing both buffer wheels 808 to contact the ground of the vehicle platform. After the two buffer wheels 808 contact and move downward, the support rod 805 rotates downward, the second spring 820 is pulled, and the fourth spring 810 is compressed. The buffer wheel 808 gives the vehicle platform an upward elastic force, realizing the buffering of the vehicle platform. As the vehicle platform continues to move downward, the elastic force given to the vehicle platform by the second spring 820 and the fourth spring 810 increases, thus realizing the buffering effect of the vehicle platform moving downward. The buffer wheel 808 and the pad 802 are aligned on the same plane until the vehicle platform is in contact with the upper surface of the buffer wheel 808. The pad 802 is made of elastic rubber and is used to support the vehicle platform to prevent hard collisions, thus achieving secondary buffering. When the vehicle platform presses against the buffer wheel 808 and moves downward, the two buffer wheels 808 open outward. Therefore, when they contact the vehicle platform and expand outward, the buffer wheel 808 rotates, preventing scratches on the lower surface of the vehicle platform. As the vehicle platform moves downward, the lifting block 806 moves downward, and the pressing block 817 presses against the lower part of the transmission plate 807 at an angle, causing the pressing plate to rotate around the guide seat 816. The guide seat 816 has an L-shaped obtuse angle structure. When rotating, the limiting wheel 803 above the guide seat 816 moves inward, so that the limiting wheel 803 moves towards the side of the vehicle platform until the side of the vehicle platform is in contact with the limiting wheel 803. When the pressing block 817 continues to move downward, the limiting wheel 803 can no longer move towards the vehicle platform. At this time, the transmission plate 807 moves outward, the guide seat 816 moves outward, and the spring 815 is compressed. When the vehicle platform stops falling, the locking rod 818 is engaged in the arc-shaped locking groove. The above implementation method can be achieved by selecting the matching of component dimensions, which is the prior art and will not be described in detail.

[0067] As the vehicle platform moves upward, before it disengages from the buffer wheel 808, the limiting wheel 803 remains in contact with the side of the vehicle platform. When the vehicle platform disengages from the buffer wheel 808, the lifting block 806 moves upward under the action of the two springs 820, causing the pressing block 817 to move upward, just enough to disengage the locking rod 818 from the arc-shaped locking groove. The above technical solution can achieve the above function through the elastic force of the spring 810, which is existing technology and will not be described in detail. The vehicle platform continues to move upward, disengages from the limiting wheel 803, and the limiting wheel 803 returns to its original position.

[0068] Rotating the rotating block 823 adjusts the distance between the nuts 821 on both sides and the center of the double-ended screw 822, thereby adjusting the distance between the two buffer wheels 808 when no external force is applied. The smaller the distance, the greater the buffer reaction force on the object. Furthermore, the opposite threads of the double-ended screw 822 ensure that the distance between the outer ends of the two springs and the center of the double-ended screw 822 can be adjusted simultaneously. The presence of spring 812 ensures that the two buffer wheels 808 always face upwards when the vehicle platform moves upwards.
