Automobile lifting type vertical and horizontal moving stereo garage

Abstract

This utility model discloses a car lift-type vertical parking garage. The vertical parking garage includes a horizontal car lift, a vertical parking frame, horizontal moving vehicles, wheel supports, and an electrical control box. The garage uses unpowered horizontal moving vehicles to carry vehicles parked on the first floor, and one car lift to lift all vehicles on the second floor. A horizontal traction device handles the horizontal movement of all vehicles on the first floor, as well as the car lift itself. The wheel supports of the second-floor vehicles move without load, resulting in low resistance and reliable movement. When loaded, the power components do not bear load, preventing vehicles from sliding or falling. There is virtually no ground-level construction work required, making it particularly suitable for converting existing single-story underground parking garages in old high-rise buildings into two-story vertical parking systems. This utility model offers advantages such as fewer power sources, high safety and reliability, and low overall cost.

Description

Technical Field

[0001] This utility model relates to the field of multi-level parking, and in particular to a car lifting and lateral moving multi-level parking garage. Background Technology

[0002] With increasing urbanization, vehicles have become an important means of transportation for people's lives. As the number of vehicles gradually increases, parking spaces are becoming increasingly scarce, leading to traffic jams and obstruction of fire lanes. Therefore, multi-level parking garages are widely used in roadside or underground parking garages. Lift-and-slide multi-level parking garages are a common type of multi-level parking garage. Currently, each parking space on the first floor of a lift-and-slide multi-level parking garage is equipped with a separate motor to drive the lateral movement, and each parking space on the second floor is equipped with a separate drive device to handle lifting. Its drawbacks are: the system is complex, with multiple power sources and control components. Furthermore, because it generally uses steel cables or chains hanging down from both sides to carry out the lifting action, it is troublesome to enter and exit parking spaces, has poor safety and reliability, and the overall cost of the equipment is high. Utility Model Content

[0003] To address one or more of the aforementioned problems, this utility model provides a car lifting and lateral sliding three-dimensional parking garage.

[0004] According to one aspect of this utility model, a car lifting and lateral sliding multi-level parking garage includes: a lateral sliding car lift, a multi-level parking space frame, a single-level lateral sliding vehicle, and wheel brackets. The lateral sliding car lift includes a lift; the multi-level parking space frame includes N single-level parking spaces and N double-level parking spaces, and the number of single-level lateral sliding vehicles is N-1; the lift and the single-level lateral sliding vehicles are capable of lateral movement; the height of the lift in its retracted state is lower than the vehicle chassis, and the height of the lift in its extended state is higher than the height of the double-level parking spaces; the wheel brackets are located in the double-level parking spaces of the multi-level parking space frame, and the number of wheel brackets is N sets; the wheel brackets, in their extended state, are used to support vehicles in the double-level parking spaces.

[0005] In some embodiments, the lateral car lift also includes a flexible roller section, a lateral traction section, and a lever mechanism. At least four sets of flexible roller sections are installed under the lift and can be laterally inserted under the vehicle chassis. Each set of flexible roller sections includes: a lateral roller, a lateral roller axle, a lateral frame, a swing hinge seat, a swing spring, and an adjusting bolt. The lateral roller is installed laterally in the lateral frame groove of the U-shaped structure through the lateral roller axle, and each lateral frame is installed vertically at the two outer corners of the lift base frame through the swing hinge seat. The swing spring is installed vertically above the swing hinge seat through the adjusting bolt. The adjusting bolt passes through the lateral hole of the lift base frame and is screwed into the threaded hole at the upper end of the lateral frame to adjust the pressure of the swing spring.

[0006] In some embodiments, the lateral traction unit includes: a traction motor, a traction sprocket, a traction chain, and guide wheels. There is one traction sprocket and three guide wheels. The traction motor is connected to the traction sprocket. A traction chain passes around the traction sprocket and the three guide wheels respectively. The two ends are connected to the center of the two outer sides of the lift chassis to form a closed loop. After the traction motor is started, the traction sprocket pulls the lift to move laterally left and right through the traction chain.

[0007] In some embodiments, the lever mechanism is installed on the middle of the two outer sides of the lift chassis. The left and right lever mechanisms each control the "left" or "right" movement. Each lever mechanism includes a swing lever, a lever connecting rod, and a lever cylinder. Two L-shaped swing levers are movably inserted into two horizontal shaft holes on each outer side of the lift chassis. The lever connecting rod connects two elbows. A lever cylinder with a spring installed in its piston rod chamber is hinged at one end to the middle section of the lever connecting rod and at the other end to the outer side of the lift chassis. When the oil cylinder chamber of the lever cylinder enters... After the hydraulic oil is applied, the piston rod extends, pulling the two swing levers to rotate upwards, making the bend vertical and higher than the height of the space below the middle of the first-level traverse car frame. This allows the first first-level traverse car in the direction of movement to be pushed, and the other first-level traverse cars in the corresponding direction are moved in the same direction by contact with the first first-level traverse car. When the lift moves alone, the lever cylinder is in the oil-draining state, and the piston rod automatically retracts under the action of the internal spring. The bend of the swing lever rotates downwards, and the height of the head end is lower than the height of the space below the middle of the first-level traverse car frame.

[0008] In some embodiments, a single-level traverse vehicle includes a vehicle body, track wheels, solid wheels, and rubber bumpers; the vehicle body includes a vehicle body beam, a vehicle platform, and a ramp plate. The vehicle platform for parking the vehicle is installed between two longitudinal horizontal vehicle body beams, and the ramp plate is installed at the outer end of the vehicle platform; a track wheel with a grooved circumference is installed on each side of the end of the vehicle body, two solid wheels are installed on each side of the front end of the vehicle body, and a pair of rubber bumpers are installed on each of the two outer sides of the front and rear ends of the vehicle body. These bumpers are used to determine the center distance between two adjacent single-level traverse vehicles and to push each other when following each other, while also providing cushioning and noise reduction in the event of a collision.

[0009] In some embodiments, each set of wheel brackets includes four sets of wheel support devices, two bracket cylinders, and two sets of linkage mechanisms; each second-level parking space is equipped with one set of wheel brackets, and each set of wheel support devices, after being extended, will support the four wheels of the vehicle respectively. The two sets of wheel support devices installed symmetrically on the same side are driven by a bracket cylinder and a set of linkage mechanisms; the wheel support device includes a swing arm assembly, a suspension end link, a swing arm shaft, a cantilever pin, a pivot bushing, and a suspension end bushing; the swing arm assembly includes a set of C-shaped groove rods of equal width and different heights that can be stacked one by one, each C-shaped rod having a vertical hole at both ends, and pivot bushings of corresponding thickness are placed above and below each swing arm shaft end hole; the suspension end bushing of corresponding thickness is embedded in the C-shaped groove of the suspension end link end hole, and is hinged to the suspension end link by inserting a cantilever pin, forming a rotatable four-bar linkage mechanism with multiple parallel swing arms.

[0010] In some embodiments, the linkage mechanism includes: a driving arm, a driven arm, and a linkage rod; the driving arm is a three-hole plate, the driven arm is a two-hole plate, and the linkage rod is a two-hole strip; the length of the C-shaped swing arm rod with the minimum height of the swing arm assembly is greater than that of the other swing arm shafts, and the swing arm shaft and the mating rotating shaft pad are keyed together; the two swing arm shafts on the same side are keyed together with the driving arm and the driven arm respectively; another hole on the driving arm and the driven arm is hinged together by the linkage rod; one end of the bracket cylinder is hinged together with the third hole of the driving arm.

[0011] In some embodiments, each set of roller support includes two sets of symmetrically arranged swing arm groups and two half-suspension end connecting rods. The C-shaped swing arm rod with the smallest height in each swing arm group is a closed rectangular tube, and a pair of meshing half-gears are symmetrically installed on the outside of the two closed rectangular tube walls at the swing arm shaft hole end. When the swing arm group retracts, the two half-suspension end connecting rods separate to the left and right, and vice versa.

[0012] In some implementations, the system also includes an electrical control box, a distance sensor, a limit switch, and an alarm, with the electrical control box electrically connected to the distance sensor, the limit switch, and the alarm.

[0013] This utility model also provides a car lifting and traversing three-dimensional parking garage, including: a multi-stage scissor lift, a multi-layer three-dimensional frame, a single-layer traversing vehicle, a wheel bracket, a multi-stage scissor lift, a multi-layer three-dimensional frame, a car carrier, a multi-layer electrical control box, a drive unit, a flat hydraulic station, a middle-layer lever mechanism, a transverse track beam, and a middle-layer traversing vehicle.

[0014] The wheel brackets for the intermediate-level vehicle tires will be installed on a transverse traverse car that can move laterally on two transverse rail beams. The transverse traverse car includes two channel steels as longitudinal beams, a rectangular horizontal frame composed of two short beams, and a pair of movable rollers that can roll along the two transverse rail beams at each end of the horizontal frame. The horizontal space within the rectangular horizontal frame is larger than the vehicle's planar projection size, and a set of wheel brackets is installed inside the frame. Specifically, two sets of wheel supports and a set of bracket cylinders and linkage mechanisms are symmetrically installed on the inner sides of the two channel steels, serving as brackets to support the tires of the intermediate-level vehicles. One transverse traverse car needs to be placed less on each section of the intermediate level to create a displacement space for the intermediate level. Here, a ground-mounted multi-stage scissor lift is used to achieve multi-level height lifting operations. The upper surface of the lifting platform in the multi-stage scissor lift is flush with the ground level of the first floor, and other components are located in the excavated tunnel. Furthermore, intermediate-level lever mechanisms are also installed on both sides of the lifting platform on the lift, which will serve as thrust components for laterally moving the transverse traverse car.

[0046] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0047] like Figures 1 to 3 As shown, the present invention schematically illustrates a car lifting and traversing multi-level parking garage, which includes a traversing car lift, a multi-level parking space rack, a first-level traversing car, a second-level bracket, and an electrical control box.

[0048] The car lift-type horizontal sliding parking system includes: a horizontal sliding car lift 1, a multi-level parking space frame 2, a single-level horizontal sliding car 3, a wheel bracket 4, and an electrical control box 5;

[0049] like Figures 4 to 6 As shown, the lateral car lift 1 is a general-purpose ultra-thin type car lift, including: lift 11, elastic roller section 12, lateral traction section 13, hydraulic station 14, lever mechanism 15, distribution valve 16, moving oil supply device 17, synchronization mechanism 18, and I-beam rail 19. The lift 11 is generally a first-level or second-level general-purpose ultra-thin scissor lift 11, which can achieve a lifting height greater than the height of a second-level parking space, and a minimum height less than the minimum ground clearance of the vehicle. In order to be able to be inserted laterally under the wheel chassis on the same ground, at least four sets of elastic roller sections 12 are installed under the lift 11 to be inserted laterally under the vehicle chassis.

[0050] like Figure 4 As shown, each set of elastic rollers 12 includes: a transverse roller 121, a transverse roller shaft 122, a transverse frame 123, a swing hinge seat 124, a swing spring 125, and an adjusting bolt 126. The transverse roller 121 is horizontally mounted in the groove of the U-shaped transverse frame 123 via the transverse roller shaft 122, and each transverse frame 123 is mounted on the two outer corners of the base frame of the lift 11 via the swing hinge seat 124, which allows it to swing up and down. The swing spring 125 passes through the adjusting bolt 126 and is mounted vertically above the swing hinge seat 124. By screwing the swing spring 125 into the threaded hole at the upper end of the transverse frame 123 through the side hole of the underframe of the lift 11, the beneficial effect is that the lower surface of the underframe of the lift 11 can be lifted off the ground when it only needs to run sideways under no-load conditions, so as not to be scraped by the ground. Once under load, the swing spring 125 will be compressed, and the underframe of the lift 11 will also drop slightly, with the lower surface pressed to the ground. When the lift 11 is lifted, the underframe is not easy to move left and right, and the underframe can bear a large load without being deformed. The lift 11 is more stable and safer when lifting vehicles.

[0051] The lift 11 is placed in the center of the parallel longitudinal single-level parking spaces. The advantage of this is that it can pass laterally under the center bottom of all the single-level traverse vehicles 3 that are parked parallel longitudinally in the single-level parking spaces.

[0052] like Figures 7 to 8As shown, the lateral movement of the lift 11 and the first-floor traverse vehicle 3 is assisted by the traverse traction unit 13 installed on the first-floor ground. The traverse traction unit 13 includes: a traction motor 131, a traction sprocket 132, a traction chain 133, and guide wheels 134. One traction sprocket 132 and three guide wheels 134 are horizontally and movably mounted on a vertical shaft support on a fixed ground. The traction motor 131 is keyed to the traction sprocket 132. One traction chain 133 passes around the traction sprocket 132 and the three guide wheels 134 respectively, and its two ends are connected to the center of the two outer sides of the lift 11 chassis. This forms a closed loop. After the traction motor 131 starts, the traction sprocket 132 pulls the lift 11 laterally and left and right through the traction chain 133, reaching the area below the chassis of the vehicle that needs to be raised to each second-floor parking space. At this time, the vehicle must be in an empty space on the first floor. Therefore, before the lift 11 moves to the empty space, it can simultaneously move the empty space, which may contain a first-floor traverse vehicle 3, or the vehicle parked above it. The beneficial effect is that it has the ability to simultaneously push multiple loaded first-floor traverse vehicles 3, and the traction chain is kept as low as possible off the ground to avoid further excavation and increase the amount of civil engineering work.

[0053] like Figures 3 to 6 As shown, the action is achieved by lever mechanisms 15 installed on the middle of the two outer sides of the lifting machine 11 base frame. The left and right lever mechanisms 15 each control the "left" or "right" movement. Each lever mechanism 15 includes a swing lever 151, a lever connecting rod 152, and a lever cylinder 153. Two L-shaped swing levers 151 are movably inserted into two horizontal shaft holes on each outer side of the lifting machine 11 base frame. The lever connecting rod 152 connects two elbows. One end of the lever cylinder 153, with a spring installed in its piston rod chamber, is hinged to the middle section of the lever connecting rod 152, and the other end is hinged to the outer side of the lifting machine 11 base frame. When hydraulic oil enters the cylinder chamber of the lever cylinder 153, the piston rod extends, pulling the two swing levers... The lever 151 rotates upward, making the bend vertical, higher than the height of the space below the middle of the frame of the first-level traverse vehicle 3. This allows the first first-level traverse vehicle 3 in the direction of movement to be pushed. Other first-level traverse vehicles 3 in the same direction are moved in the same direction by contact with the first first-level traverse vehicle 3. When the lift 11 moves alone, the lever cylinder 153 is in the oil-discharging state. Under the action of the internal spring, the piston rod automatically retracts, and the bend of the lever 151 rotates downward, with the head height lower than the height of the space below the middle of the frame of the first-level traverse vehicle 3. The beneficial effect is that while moving the lift 11, other first-level traverse vehicles 3 that need to be moved can be pushed. The lever cylinder 153 uses a spring return, which can reduce one oil supply pipe.

[0054] like Figures 7 to 8As shown, the hydraulic cylinders 153 and 11 (lifting cylinders) are supplied with oil from the hydraulic station 14, the mobile oil delivery device 17, and the distribution valve 16. The hydraulic station 14 is installed on the inner end of the ground. Because the hydraulic cylinders 153 and 11 move laterally at any time, the mobile oil delivery device 17 needs to be equipped with a function that allows the oil delivery length to change at any time. This includes a hydraulic rotary joint 171, a hose reel 172, an oil delivery hose 173, and a pressure roller 174. The hydraulic oil output from the hydraulic station 14 is connected to the hydraulic rotary joint 171 via a rigid pipe, both fixed to a spindle. The rotating valve sleeve is connected to one end of a sufficiently long oil delivery hose 173, and is installed... The system is equipped with an automatic hose reel 172, with the oil hose 173 wound around the hose reel 172 in multiple turns. The rotating frame of the hose reel 172 and the pressure roller 174 is installed on the ground near the hydraulic station 14. The other end of the oil hose 173 is stably routed by the pressure roller 174 and attached to the outside of the traction chain 133. Guided by the guide wheel 134, it is connected to the distribution valve 16 installed on the side of the base frame of the lift 11. The electromagnetically controlled distribution valve 16 outputs two paths: one to the lever cylinder 153 and the other to the lifting cylinder of the lift 11. Both are single-acting cylinders; the former returns to its original position by spring, and the latter is compressed by gravity.

[0055] A typical car lift uses two parallel scissor lift mechanisms and two parallel lifting cylinders. Since the load on the left and right sides of the vehicle may not be the same, this can cause inconsistent lifting of the parallel lifting cylinders and scissor lift mechanisms. Here, a gear and rack mechanical synchronization mechanism 18 is used for synchronization. The synchronization mechanism 18 includes a synchronization gear 181, a synchronization coupling 182, and a synchronization rack 183. The two axial inner sides of the moving rollers or sliders on the inner side of the moving fork arms of the two parallel scissor lift mechanisms are extended, and each is connected to a synchronization gear 181 via a key sleeve. Each synchronization gear 181 meshes downwards with the synchronization rack 183. 3. The horizontal gears are fixed on the base frame of the lifting machine 11. At the same time, the inner end faces of the two synchronous gears 181 are rigidly connected by the synchronous coupling 182. The synchronous rack 183 is greater than the moving distance of the roller or slider under the scissor arm. When the moving roller or slider under one scissor mechanism may move faster than the other, at this moment, due to the relative movement of the gears and racks, the faster synchronous gear 181 generates an assist torque on the slower synchronous gear 181 through the synchronous coupling 182, thereby achieving dynamic balance and synchronization between the two. The beneficial effect is that the parallel lifting cylinders achieve dynamic balance and the two scissor mechanisms lift and lower synchronously.

[0056] The I-beam rail 19 is a standard I-beam rail, parallel to the central traction chain 133 of the traction lift 11. It can be directly installed on the inner side of the ground, and its length is approximately equal to the lateral length of the first-floor parking space. The rail is used to guide and support the first-floor traverse vehicle 3. A rail stop 191 is installed at each end to restrict the first-floor traverse vehicle 3 from moving out of the parking area. The beneficial effects are: the first-floor traverse vehicle 3 can move laterally in a straight line, and the movement of the first-floor traverse vehicle 3 out of the parking area is restricted.

[0057] The beneficial effect is that by using a conventional ultra-thin car lift structure that can move laterally, it is possible to move the lift 11 and all the first-floor lateral moving vehicles 3 laterally, and also to lift all the second-floor vehicles, thus achieving the goal of low overall garage cost.

[0058] like Figures 1 to 3 As shown, the three-dimensional parking frame 2 includes: uprights 21, transverse beams 22, end beams 23, guardrails 24, and H-beams 25. Generally, at least two uprights 21, two transverse beams 22, and two end beams 23 form a rectangular three-dimensional large space frame, occupying the entire area and space of the first-floor parking space, while bearing the weight of all vehicles on the second floor. Guardrails 24 are installed on the transverse beams 22 to prevent possible wheel slippage or falling accidents on the second floor. Multiple H-beams 25 are spaced one parking space width apart, parallel to each other, and connected at both ends to the inner side of the front and rear transverse beams 22. The space between two adjacent H-beams 25 is a second-floor parking space, that is, each H-beam 25 can bear the weight of at least one vehicle. The beneficial effect is that the all-steel structure is compact, sturdy, safe, and durable.

[0059] like Figures 9 to 11As shown, the single-level traverse vehicle 3 includes: a vehicle body 31, track wheels 32, solid wheels 33, rubber impact blocks 34, and traction impact blocks 35. The single-level traverse vehicle 3 is a low-height vehicle that allows vehicles parked on one level to move laterally on one level of ground without powered wheels. The vehicle body 31 includes a vehicle body beam 311, a vehicle platform 312, and a ramp 313. The vehicle platform 312 is installed between two longitudinal horizontal vehicle body beams 311. The inner end of the vehicle body beam 311 and the lower part of the vehicle platform 312 are supported and reinforced by crossbeam steel. The ramp 313 is installed at the outer end of the vehicle platform 312 for vehicles parked on one level to climb uphill and park on the vehicle platform 312 of the single-level traverse vehicle 3. A track wheel 32 with grooves on its circumference is installed on each side of the end of the vehicle body 31. The track wheels 32 will run on the I-beam rails 19. Two solid wheels 33 are installed on each side of the front end of the car body 31, or multiple solid wheels 33 are installed on both sides of the middle section. After all the wheels are installed, the car platform 312 can remain horizontal whether it is empty or fully loaded, and when it moves laterally. A pair of rubber bumpers 34 are installed on each of the two outer sides of the front and rear ends of the car body 31. They are used to determine the center distance between two adjacent single-level traverse cars 3 and to push each other when they follow each other. At the same time, they can buffer and muffle the collision. A pair of traction bumpers 35 are installed in the middle of the two outer sides of the car body 31 at the vertical position of a pair of swing levers 151 on the lever mechanism 15 of the corresponding lift 11. The traction bumpers 35 can be made of soft rubber material. When the swing levers 151 push against them, they can buffer and muffle the noise.

[0060] The beneficial effects are: all the single-level traverse vehicles are unpowered, have a simple structure, low cost, and utilize the lateral movement of the lift to simultaneously complete the side movement of the single-level traverse vehicles, making operation convenient and fast.

[0061] like Figures 12 to 14 As shown, the wheel bracket 4 includes four sets of wheel supporters 41, two bracket cylinders 42, and two sets of linkage mechanisms 43. Each second-floor parking space is equipped with one set of wheel brackets 4. After each set of wheel supporters 41 extends and unfolds, it will support the four wheels of the vehicle. The two sets of wheel supporters 41 installed symmetrically on the same side are driven by a bracket cylinder 42 and a set of linkage mechanisms 43. The four wheel supporters 41 are installed on the inner side of the H-beams 25 on both sides of each second-floor parking space. After the wheel supporters 41 unfold and rotate out, they are located in the area below the position of each wheel of the second-floor vehicle, thereby achieving support and parking for the second-floor vehicle.

[0062] like Figures 15 to 18As shown, this is one of the preferred embodiments of the roller support 41: The roller support 41 includes a swing arm assembly 411, a suspension end connecting rod 412, a swing arm shaft 413, a cantilever pin 414, a pivot bushing 415, and a suspension end bushing 416; the swing arm assembly 411 is composed of a group (5 to 9) of C-shaped groove rods with equal widths but unequal heights, which can be stacked one by one. Each C-shaped rod has a vertical hole at each end. The upper and lower ends of each swing arm shaft 413 end hole are respectively fitted with pivot bushings 415 of corresponding thickness. The upper and lower swing arm shafts 413 at this end are coaxially hinged into the vertical holes of the wing plates of the H-beam 25; the suspension end connecting rod 412 end hole C-shaped groove is fitted with a suspension end bushing 416 of corresponding thickness. This end is hinged to the suspension end connecting rod 412 by inserting the cantilever pin 414, forming a rotatable four-bar linkage with multiple parallel swing arms;

[0063] like Figure 14 As shown, the left swing arm assembly 411 is in a fully rotated-in, overlapping state, which reduces the overall width of the swing arm assembly 411 and allows it to be folded horizontally into the H-beam 25 groove; the right swing arm assembly 411 is in a fully rotated-out, unfolded state, with the upper surface being rectangular after rotation, which can support one tire of the vehicle.

[0064] like Figure 18 The figure shows a cross-sectional view of the interlocking and overlapping state of the swing arm assembly 411 after it has been fully rotated in.

[0065] The linkage mechanism 43 includes: an active arm 431, a driven arm 432, and a linkage rod 433; the active arm 431 is a three-hole plate, the driven arm 432 is a two-hole plate, and the linkage rod 433 is a two-hole strip; the swing arm shaft 413 of the C-shaped swing arm rod with the minimum height of the swing arm assembly 411 is lengthened, and its top or bottom end extends beyond the wing plate of the H-beam 25; the swing arm shaft 413 and the pivot bushing 415 are machined with keyways, and after the corresponding key strips are installed, the top (or bottom) ends of the two swing arm shafts 413 on the same side are keyed to the active arm 431 and the driven arm 432 respectively; another hole on the active arm 431 and the driven arm 432 is hinged to the linkage rod 433; one end of the bracket cylinder 42 is hinged to the third hole of the active arm 431, and the other end is hinged to the upper (or lower) plane of the wing plate of the H-beam 25; whenever the bracket cylinder 42 retracts, it pushes the active arm 431 to rotate, thus... The horizontally arranged linkage 433 drives the boom 432 to rotate in opposite directions at the same angle, causing both wheel supports 41 on the same side to rotate towards the center of the vehicle (to support the vehicle's tires) or in the opposite direction (to retract into the groove of the H-beam 25). This completes the parking or retrieval operation for each second-floor vehicle. Because each linkage 433 is horizontally arranged in an oblique direction, if two adjacent linkage mechanisms 43 installed on the same H-beam 25 are located on the same plane, motion interference will occur. Therefore, the two adjacent linkage mechanisms 43 are installed on the upper or lower plane of the H-beam 25 respectively; or the horizontal distance between them needs to be increased, which increases the width of the H-beam 25 and the width of the two adjacent parking spaces, which is not conducive to saving parking space and reducing steel structure costs. When the hydraulic oil pipe is long, the bracket cylinder 42 can be replaced by an electric push rod.

[0066] The beneficial effects are: the wheel carrier moves with low resistance and reliable movement when there is no load, and when under load, the power component does not bear the load, and the load force is not consistent with the direction of movement of the wheel carrier. Therefore, the wheel carrier is not easy to lose its position and the vehicle is not easy to slip or fall. It is especially suitable for the conversion of the original single-story underground garage of old high-rise buildings into a two-story multi-level parking system.

[0067] Furthermore, such as Figures 19 to 21 As shown, to increase the strength of the swing arm assembly 411 and better adapt to supporting the wheel arc, and to reduce the overall width of the swing arm assembly 411 after retraction, the swing arm assembly 411 is divided into two symmetrical halves, and the suspension connecting rod 412 is cut into two equal segments. Furthermore, the C-shaped swing arm rod with the smallest height in each half of the swing arm assembly 411 is replaced with a closed rectangular tube. A pair of meshing half-plate gears 417 are symmetrically installed on the outer walls of the two closed rectangular tubes at the hole end of the swing arm shaft 413, forming a "V"-shaped symmetrical expansion or contraction movement. When the swing arm assembly 411 retracts, the two halves of the suspension connecting rod 412 separate to the left and right, and vice versa. Replacing the two middle C-shaped swing arm rods with closed rectangular tubes increases the strength and rigidity of the swing arm assembly 411. Figure 20The central linkage mechanism 43 is located below the H-beam 25;

[0068] The beneficial effects are: the “V” shaped symmetrical structure, with the upper surface of each wheel support having a concave contour surface, better fits the circumference of the wheel pressing surface, making the vehicle more stable when parked and less likely to move back and forth. In addition, the two sides are separated and overlapped, and the overall width is smaller after shrinking, which allows for a smaller distance between the two parking spaces.

[0069] The electrical control box 5 includes electrical components such as a distance sensor, limit switch, and alarm. It is the program control and operation box for the equipment and can be mounted on the side of the middle section of a column.

[0070] All vehicles on the first floor of the automated parking garage drive to the first-floor traverse vehicle 3 for parking. In the same row of first-floor parking spaces, at least one less first-floor traverse vehicle 3 is placed, which serves as the entrance and exit for the second-floor vehicles. The equipment program control only performs storage and retrieval operations for second-floor vehicles.

[0071] Initial state of the actuator:

[0072] 1. In each second-level parking space, the two bracket cylinders 42 of the wheel bracket 4 are in the retracted state, and the four sets of wheel support devices 41 are all retracted into the H-beam 25 groove;

[0073] 2. The lifting machine 11 and the two lever mechanisms 15 are both in the lowest descent state;

[0074] 3. The procedure for storing and retrieving parking spaces on the second floor is as follows: Parking spaces in the same row on the second floor are first numbered sequentially as 1, 2, 3...;

[0075] First and second floor vehicle storage operation steps:

[0076] Driver A presses the "Serial Number" button for the second empty slot in the control box 5, and then presses the "Store" button.

[0077] Based on the "position" of the empty space on the first floor, the sensor b starts the traction motor 131, pulls the lift 11 to the direct below the corresponding first-floor traverse vehicle 3, and supplies oil to the left or right side lever cylinder 153 of the lift 11, so that the swing lever 151 in the corresponding side lever mechanism 15 rises.

[0078] The traction motor 131 is restarted, the lift 11 moves to the left or right, the raised swing lever 15 pushes all the first-floor lateral trolleys 3 on this side, fills the original first-floor empty space, and at the same time selects the empty parking space below the second floor "serial number" to become the new first-floor empty space. At this moment, the lift 11 also reaches the position.

[0079] After the driver drives the vehicle to the empty space on the first floor, he gets off the vehicle, straddles the lift 11, and supplies oil to the lifting cylinder of the lift 11. The lift then lifts the vehicle chassis and raises it to its highest point.

[0080] e supplies oil to the bracket cylinder 42 of the wheel bracket 4 groups on the second-floor empty parking space, and the swing arm 411 of the four wheel support 41 unfolds and rotates to under the four tires of the vehicle.

[0081] f releases oil from the lifting cylinder of the lift 11, the vehicle chassis is removed from the lift, the four wheels of the vehicle are supported by the wheel support 41, the lift is lowered to the lowest point, and at the same time, oil is released from the lever cylinder 153. Under the action of the spring installed in the piston rod chamber, the piston rod retracts, and the swing lever 151 rotates and lowers to the lowest point.

[0082] Complete a parking operation for a vehicle in a second-level parking space.

[0083] Steps for retrieving vehicles from the second floor:

[0084] The driver first presses the "serial number" button for the parking space on the second floor of the electronic control box 5, and then presses the "retrieve" button;

[0085] According to the "position" of the first-floor empty space, the i-sensor restarts the traction motor 131, pulls the lift 11 to the left or right side of the second-floor retrieval vehicle parking space below the horizontal moving vehicle 3, and supplies oil to the corresponding side lever cylinder 153 of the lift 11, causing the swing lever 151 in the corresponding side lever mechanism 15 to rise.

[0086] The traction motor 131 restarts, the lift 11 moves to the left or right, the raised swing lever 15 pushes all the first-floor lateral sliding vehicles 3 on this side, filling the original first-floor empty space. At the same time, the lift 11 reaches the position of the new empty space below the second-floor vehicle parking space.

[0087] K supplies oil to the lifting cylinder of the lift 11, and the lift rises to the highest point, lifting the chassis of the two-story vehicle, and the vehicle tires are separated from the four roller supports 41.

[0088] The oil supply is provided to the piston rod chamber of the hydraulic cylinder 42 of the wheel bracket 4 group of the second-level parking space, and the swing arm group 411 of the four wheel brackets 41 retracts and rotates into the groove of the H-beam 25.

[0089] g releases oil from the lifting cylinder of the lift 11, and the lift lowers the vehicle to its lowest point, with the vehicle wheels supported on the ground and the vehicle chassis detached from the lift. At the same time, oil is released from the lever cylinder 153, and the rising swing lever 151 lowers to its lowest point.

[0090] The driver gets into the vehicle and drives it over the lift 11, creating one level of space.

[0091] Complete the retrieval of a vehicle from a second-level parking space.

[0092] The beneficial effects are: a single lateral traction mechanism realizes the lateral displacement of the lift and completes the lateral displacement of all vehicles on the first floor; at the same time, a single car lift completes the lifting and lowering operations for all vehicles on the second floor. Therefore, this car lift-type lifting and lateral parking garage has fewer handling equipment, unified actions, simple procedures, fewer power components, and easy-to-operate electrical control box. It is suitable for use in the underground two-story parking garages of current high-rise buildings, and is significantly cheaper than the currently commonly used underground lifting and lateral two-story parking garages.

[0093] Furthermore, such as Figure 22 As shown, in the case of two rows of lift-and-slide multi-level parking garages that are typically arranged parallel to each other on the ground floor, the lifts 11 of these two rows of lift-and-slide multi-level parking garages and all the slide cars 3 on the first floor can share a set of slide traction units 13. That is, two lifts 11 are connected in series symmetrically on a traction chain 133, and two hose guide wheels 175 are added, and two hydraulic oil and oil delivery devices are arranged appropriately. The beneficial effect is that it is suitable for use in underground parking garages of commercial buildings, and the vehicles do not enter and exit in a concentrated manner, which can greatly reduce the manufacturing cost.

[0094] Furthermore, when the minimum height of the car lift cannot be made lower than the minimum ground clearance of the vehicle chassis, or when the number of floors in the multi-level parking garage is greater than two, the lateral movement of the car lift will be achieved by excavating a tunnel. The beneficial effects are: it can increase the strength and height of the car lift, and the hydraulic station can be placed on the lift, eliminating the need for a complex mobile oil delivery device 17.

[0095] like Figure 23 As shown, taking a three-story automated parking garage as an example, the differences between multi-story lift-and-slide automated parking garages are:

[0096] Here, the parking space of the multi-level rack 20 has more than two levels. It is not a single level or the top level. The two transverse beams of the middle level are set as continuous transverse track beams 220. That is, there are no fixed H-beams 25 on the middle level. The wheel brackets 4 of the vehicles in the middle level are installed on the two transverse track beams 220 and can move laterally on the middle level traverse vehicle 6. The middle level traverse vehicle 6 includes two channel steels 61 as longitudinal beams, a rectangular horizontal frame composed of two short beams 62, and a pair of movable rollers 63 installed at each of the front and rear ends of the horizontal frame, which can roll along the front and rear transverse track beams 220. The horizontal space dimension within the rectangular horizontal frame is larger than the vehicle's planar projection dimension, and the frame... A set of wheel brackets 4 is installed on the inner side of the frame. That is, two sets of wheel supporters 41 and a set of bracket cylinders 42 and linkage mechanism 43 are symmetrically installed on the inner side of the two channel steels 61. These serve as brackets to support the tires of the vehicles stored in the middle layer. Each middle layer lateral transfer car 6 needs to be placed one less to serve as a displacement space for the middle layer. Here, a ground-mounted multi-stage scissor lift is used to realize the lifting operation of multiple layers. The upper surface of the lifting platform of the multi-stage scissor lift 10 is flush with the ground of the first layer. Other components are located in the excavated tunnel. The two outer sides of the lifting platform on the lift are also equipped with middle layer levers 150, which will serve as thrust components for lateral movement of the middle layer lateral transfer car 6.

[0097] Since all components of the lift 10 do not need to be higher than the ground, the vehicle platform on the first-level vehicle platform 30 is flat and does not need to be raised in the middle. Furthermore, the hydraulic station of the multi-stage scissor lift adopts a flat hydraulic station 140, which is installed on the base frame of the multi-stage scissor lift 10 and can move with it. Therefore, there is no need to move the oil supply device 17 here. The lateral drive device 130 can be installed vertically, and only one drive sprocket and one guide wheel are needed.

[0098] Here, the program data of the multi-level electrical control box 50 needs to be supplemented with the "serial number" of the intermediate level, and a "level" button needs to be added to the operation panel; all bracket cylinders 42 and lever cylinders 153 in the multi-level lifting and traversing parking garage are recommended to be replaced with electric push rods.

[0099] The difference between operating a multi-level lift-and-slide automated parking system and a two-level lift-and-slide automated parking system is that you need to first select the "number of levels", then select the "number of positions", and finally select "entry" or "exit".

[0100] The operation of the equipment will include the movement of the middle-level traverse car 6 and the coordination of the wheel bracket 4 on the middle-level traverse car 6.

[0101] The beneficial effects are: a single lateral traction mechanism enables the lateral displacement of the lift and completes the lateral displacement of all vehicles on the first and middle floors. At the same time, a single car lift completes all lifting operations for all vehicles above the first floor. After the civil engineering work is added, it is suitable for development into a multi-story parking garage. It basically retains the handling equipment form of the original two-story parking garage, with fewer power sources, simpler equipment, and lower cost. It is suitable for new above-ground or underground parking garage projects and renovation projects that need to increase parking spaces.

[0102] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
