Description

Technical Field

[0001] This utility model relates to the field of garages, and more particularly to a multi-entrance, multi-level garage equipped with a movable lifting mechanism. Background Technology

[0002] With the acceleration of urbanization, the number of motor vehicles in cities has increased dramatically, and parking problems have become increasingly prominent. Currently, urban parking resources are scarce, and problems such as difficulty and disorder in parking are commonplace, seriously affecting citizens' travel experience and urban traffic order. Optimizing parking management and improving parking service levels have become urgent issues to be addressed in the urban transportation sector. Mechanical parking equipment, as an important technical means to solve urban parking problems, is being increasingly widely used.

[0003] Traditional mechanical automated parking systems typically employ a single entrance / exit design, relying on a single lifting channel for parking and retrieval. This results in low efficiency, with an average waiting time exceeding 5 minutes and severe queuing during peak hours. To address the inefficiency of a single entrance / exit, additional lifting channels are needed. For example, vertical lifting systems require an additional lifting system for each channel added, increasing costs by 30%-50%. Similarly, lifting and traversing systems, with their independent power supply for each parking space, require a separate lifting power unit for each group, further driving up equipment costs.

[0004] Furthermore, traditional mechanical automated parking systems mount lateral movement power onto the lateral frame, with each lateral vehicle independently powered. However, their power supply often employs cycloidal lines, cable chains, or sliding contact lines, which are prone to slippage. Cable chains are susceptible to short circuits and arcing due to mechanical wear, resulting in high maintenance costs. Additionally, the lateral wheels use channeled steel wheels pressed onto square tracks, but the channels are often shallow, posing a significant risk of derailment when the frame deforms or the load is uneven. The large wheelbase of the lateral frame also leads to insufficient rigidity, causing track wear and misalignment under dynamic loads, creating further safety hazards. Utility Model Content

[0005] The purpose of this utility model is to address the problems in the background technology, such as the low efficiency of relying on a single lifting channel for vehicle storage and retrieval, the need for the lifting system to be increased synchronously according to the number of channels, high cost, and the easy wear and tear of the track under dynamic loads, which poses safety hazards.

[0017] Example 1: This utility model proposes a multi-entrance, multi-level parking garage equipped with a movable lifting mechanism, comprising: The steel frame 1 includes multiple columns 101 in two rows, multiple horizontal beams 102 arranged side-by-side inside the columns 101, and multiple longitudinal beams 103 arranged side-by-side between the opposing columns 101. The steel frame 1 forms a multi-row parking structure. It is important to note that the steel frame 1 is only long enough for one vehicle to park in the front-to-back direction. The "multi-row" designation refers to the horizontal arrangement from a frontal view. A support base 105 is located at the middle of the rear side of the steel frame 1. To enhance the overall frame strength, multiple diagonal angle steels 104 are installed between adjacent longitudinal beams 103 and adjacent horizontal beams 102. The columns 101, horizontal beams 102, longitudinal beams 103, and diagonal angle steels 104 are all fixedly connected by steel bolts. The steel frame 1 is a modular structure with multiple horizontal rows and a variable number of vertical layers, allowing for rapid reconfiguration of the parking garage shape according to site characteristics. Figure 1 and Figure 2 As shown; The lateral moving platform 7 is slidably mounted on the front and rear crossbeams 102. The number of lateral moving platforms 7 in each row is one less than the number of parking spaces, thus creating a row that is completely empty of vehicles and lateral moving platforms 7. Each lateral moving platform 7 is equipped with a lateral moving drive 8, which drives the lateral moving platform 7 to move laterally. Figure 8 As shown; The lifting platform 6 is vertically slidably mounted on four adjacent columns 101. The lifting platform 6 and the transverse platform 7 can alternate in the same column to complete the transfer of the vehicle from the transverse platform 7 to the lifting platform 6; Figure 7 As shown; The transverse frame is set on the top of the steel structure frame 1 along the transverse sliding direction. After the lifting platform 6 moves to the top, it can change its transverse position through the transverse frame, so that the lifting platform 6 can be dispatched across areas. And the lifting power unit lateral movement mechanism 3, which is laterally slidably mounted on the support base 105, on which the lifting power unit 2 is mounted to drive the lifting platform 6 to rise and fall; such as Figure 3 and Figure 4 As shown.

[0018] Example 2: This utility model proposes a multi-entrance, multi-level parking garage equipped with a movable lifting power unit. Compared with Example 1, this example details the structure of the lifting power unit lateral movement mechanism 3 and the lifting power unit 2. like Figure 4 As shown, the lifting power unit lateral movement mechanism 3 includes a lateral movement fixed base, a lateral movement motor 301 mounted on the lateral movement fixed base, a lateral movement wheel 302 mounted on the output shaft of the lateral movement motor 301, an I-beam lateral movement track 304 laterally mounted on the support base 105, and two lateral movement guide wheel sets 303 rotatably mounted on the lateral movement fixed base; the bottom of the lateral movement wheel 302 rolls in contact with the top of the I-beam lateral movement track 304, and the lateral movement power is provided by the lateral movement wheel 302; the two lateral movement guide wheel sets 303 clamp the web of the I-beam lateral movement track 304 from the front and rear sides respectively; the lateral movement motor 301 drives the lateral movement wheel 302 by a coupling.

[0019] like Figure 3As shown, the lifting power unit 2 includes a steel structure fixing component 204 mounted on a transverse fixed base, a left wire rope drum 201 and a right wire rope drum 202 mounted on the steel structure fixing component 204 via a drum connecting shaft 205, and a lifting motor 203 mounted on the steel structure fixing component 204 that drives the left wire rope drum 201 and the right wire rope drum 202 to rotate. Specifically, both the output shaft of the lifting motor 203 and the drum connecting shaft 205 are equipped with transmission sprockets 206, which are connected by a chain drive. Two fixed pulleys are mounted on the transverse frame, and the wires on the left wire rope drum 201 and the right wire rope drum 202 pass upwards over the fixed pulleys and connect to the lifting platform 6. The steel structure fixing component 204 and... The transverse frame is connected, thereby driving the transverse frame to move horizontally synchronously; the lifting power unit 2 of the present invention adopts a non-friction power transmission structure with a motor chain driving a steel wire rope drum; the transverse fixed seat is a mounting plate 207 set at both ends of the steel structure fixed component 204; therefore, the lifting power unit 2 realizes the vertical direction by using a motor to drive the steel wire rope drum, forcibly traction the steel wire rope to drive through the fixed pulley block at the top of the equipment steel structure, guides the lifting lifting platform 6, and the horizontal transverse mechanism 3 of the lifting power unit uses the transverse motor 301 to drive the entire transverse frame and the lifting power unit 2 installed on the transverse frame to move horizontally, which can realize cross-regional scheduling through the movable lifting power unit 2 and support the parallel operation of 2-4 independent entrances and exits.

[0020] Example 3: This utility model proposes a multi-entrance, multi-level parking garage equipped with a movable lifting mechanism. Compared with Example 2, this example details the structure of the lifting platform 6 and the lateral moving platform 7. like Figure 7 As shown, the lifting platform 6 includes two symmetrical left comb tooth assemblies 601 and right comb tooth assemblies 602. Both the left comb tooth assembly 601 and the right comb tooth assembly 602 include multiple front comb teeth and multiple rear comb teeth. The front and rear comb teeth are fixed on a longitudinal channel steel and have the same spacing. Both ends of the left comb tooth assembly 601 and the right comb tooth assembly 602 are provided with vertically moving lifting guide systems 5.

[0021] like Figure 8 and Figure 10As shown, the transverse platform 7 is a rectangular frame structure. Multiple forward transverse comb teeth 703 are located on the left and right sides of the front end of the frame, and multiple backward transverse comb teeth 704 are located at the rear end. The forward and backward transverse comb teeth 703 and 704 are of the same length and have the same spacing. The forward and backward transverse comb teeth 703 and 704 correspond alternately with the front and rear comb teeth of the lifting platform 6 for exchanging and parking vehicles. The transverse platform 7 has a front grooved track 701 and a rear grooved track 702 at its front and rear ends. An oil drip plate 705 is installed in the upper middle part of the transverse platform 7 to prevent liquid from flowing down and contaminating vehicles below, which also complies with relevant regulations. The specifications stipulate that a transverse transmission 8 is installed on the steel frame 1 to drive the transverse moving platform 7 laterally. The main body of the transverse transmission 8 is a square tube transverse transmission beam 801. Multiple friction rollers 803 are horizontally mounted on the transverse transmission beam 801, with the upper surfaces of all friction rollers 803 on a horizontal plane. Several transverse transmission sprockets 805 are also mounted at one end of each friction roller 803. The transverse transmission sprockets 805 are staggered on the vertical plane and power is transmitted via a series of transverse transmission chains 806. The transverse transmission chains 806 are driven by a transverse transmission motor 802 mounted on the upper end of the square tube structure of the transverse transmission beam 801. A tensioning sprocket 804 is also provided on the transverse transmission chain 806 to adjust its tension. The transverse transmission 8 is arranged on the crossbeam 102 of the steel structure frame on each floor. The transverse transmission 8 is provided at the front and rear of each row of parking spaces on the second floor and above. The transverse transmission 8 corresponds to the transverse car plate on each floor. When the transverse transmission motor 802 is energized and rotates, it drives the transverse transmission chain 806 to transmit power to each transverse transmission sprocket 805. The transverse transmission sprocket 805 drives several friction rollers 803 to rotate together. The friction of the rotating friction rollers 803 drives the transverse car plate 7, which is tightly fastened to the front groove track 701 and the rear groove track 702, to move horizontally.

[0022] like Figure 11 As shown, each parking level has several horizontally arranged traverse pallets 7. The front groove-shaped track 701 and rear groove-shaped track 702 of each traverse pallet 7 are placed on the traverse transmission 8. The number of horizontally distributed traverse pallets 7 is N-1, which is one less than the number of rows N of the equipment. The empty row is used as the lifting channel for the lifting pallets 6. When a car needs to be stored or retrieved, the traverse pallets 7 located in the lifting channel above the entrance / exit must move horizontally to the left and right, only if there are no traverse pallets 7 in the lifting channel above the entrance / exit, and the lifting pallet 6 is located at the first-floor entrance / exit. The control system initiates the car storage / retrieval procedure as follows: the corresponding traverse transmission motor 802 of the traverse transmission 8 starts, driving the friction roller 803 to rotate. The traverse pallets 7 of that level and those needing to clear the entrance / exit channel move horizontally to both sides of the channel. Furthermore, the control system optimizes the calculation so that several traverse pallets 7 of that level or other levels that need to move move simultaneously, ensuring that there are no parking spaces in the channel above the entrance / exit, thus saving traverse time.

[0023] like Figure 9 The diagram shows the exchange of vehicles using the lifting platform 6 and the lateral moving platform 7, providing a more detailed explanation of the comb tooth exchange principle. Specifically, the lifting platform 6 is composed of two separate symmetrical comb tooth assemblies. The left and right assemblies operate independently but are synchronized through left and right steel wire rope drums. Each assembly has several comb teeth arranged front and back, with equal spacing between the teeth to ensure uniform force distribution. The tips of all comb teeth face the center axis of the platform, facilitating precise alignment and engagement during the exchange process. The lateral moving platform 7 is a frame structure with a front grooved track 701 and a rear grooved track 702. Several lateral moving front comb teeth 703 and lateral moving rear comb teeth 704 are located on both sides of the frame, facing outwards and spaced equally; a symmetrical layout. The comb teeth of the lateral moving platform 7 are alternately arranged with corresponding comb teeth of the lifting platform 6, with equal spacing. Furthermore, during vehicle storage, after the lifting platform 6, carrying the target vehicle, is raised to a predetermined position above the target layer, the lateral moving platform 7 moves horizontally to a position directly below the lifting platform 6. The lifting platform 6 then descends, and through a comb-tooth exchange mechanism, the vehicle is transferred from the lifting platform 6 to the lateral moving platform 7. After the exchange is complete, the lifting platform 6 continues to descend until it reaches its final position. After a safety delay, the control system initiates the reset of the lateral moving platform 7 to its original position, completing the vehicle storage process.

[0024] like Figure 9 As shown, when retrieving a car, after the control system receives the command to retrieve the car from the target parking space, the target lateral moving platform 7 moves horizontally to the center position of the entrance / exit shaft. The lifting platform 6 rises via frequency conversion, decelerating and switching when it approaches the target lateral moving platform 7, until the car is transferred onto the comb frame of the lifting platform 6. After continuing to rise to the set position, it stops. At this point, after the lateral moving platform 7 returns to its original position, the control system starts the lifting platform 6 to descend until it reaches the desired position, completing the car retrieval process.

[0025] Example 4: This utility model proposes a multi-entrance, multi-level parking garage equipped with a movable lifting power system. Compared with Example 3, this example details the structure of the locking and positioning mechanism 4, the lifting and guiding system 5, and the filling platform 9. like Figure 7As shown, the lifting and guiding system 5 includes a left lifting arm 501 and a right lifting arm 502 located at both ends of the left comb assembly 601 and the right comb assembly 602. Both the left lifting arm 501 and the right lifting arm 502 have a square main structure. The left lifting arm 501 and the right lifting arm 502 are also symmetrical components, which are installed alternately and symmetrically at both ends of the left comb assembly 601 and the right comb assembly 602. That is, the left lifting arm 501 is installed at the front end of the left comb assembly 601 and the right lifting arm 502 is installed at the rear end, and the right lifting arm 502 is installed at the front end of the right comb assembly 602 and the left lifting arm 501 is installed at the rear end. The square main structure of the left lifting arm 501 and the right lifting arm 502 is provided with left and right guide wheels 503 and front and rear guide wheels 504. The left and right guide wheels 503 and the front and rear guide wheels 504 are in contact with the inner wing plate and web plate of the H-shaped steel of the steel structure frame 1, respectively, to ensure that the lifting platform 6 can run smoothly and at high speed.

[0026] like Figure 7 As shown, a lifting rod 505 is provided at the top of the left lifting arm 501 and the right lifting arm 502. The lifting rod 505 is used to connect with the ends of the wire ropes of the left wire rope drum 201 and the right wire rope drum 202. A compression spring 506 is sleeved on the lifting rod 505. The bottom of the compression spring 506 is connected to the bottom of the lifting rod 505, and the top of the compression spring 506 is connected to the left lifting arm 501 or the right lifting arm 502.

[0027] like Figure 5 and Figure 6As shown, a locking and positioning mechanism 4 is provided between the transverse frame and the lifting platform 6. The lifting platform 6 moves upward to initial locking. When the lifting platform 6 continues to rise and then falls, it engages the lock. After the lifting platform 6 moves to the highest point, it disengages from the column 101 and moves laterally above the column 101 after being driven by the transverse frame. It stops after reaching the desired position. After the lifting platform 6 falls, it re-enters the sliding engagement with the other columns 101, thereby horizontally adjusting the position of the lifting platform 6. Specifically, a positioning seat 402 with an opening facing downward is provided at each of the four corners of the bottom of the transverse frame. A sliding hole is provided on both sides of the opening of the positioning seat 402. A spring pin 404 is slidably installed in the sliding hole. One end of the spring pin 404 is a pointed tip and is inserted into the cavity of the positioning seat 402. The other end of the spring pin 404 is provided with an external thread and passes through the wall of the sliding hole. An adjusting nut 406 is provided on the external thread. A spring 405 is sleeved on the external thread section of the spring pin 404. In the compressed state; a positioning pin 401 is provided at the top of either the left lifting arm 501 or the right lifting arm 502. The top of the positioning pin 401 is a pointed tip that can be smoothly inserted into the positioning seat 402. The top of the positioning pin 401 is provided with a groove, and a positioning slip ring 403 is slidably installed in the groove along the vertical direction. The working process is described in detail below: When dispatching across areas, the lifting power unit 2 lifts the lifting platform 6 to the top. The positioning pin 401 is inserted into the positioning seat 402. The arc surface at the top of the positioning pin 401 pushes the spring pin 404 to compress the spring 405 and pushes the spring pin 404 back. After the positioning pin 401 continues to rise, the spring pin 404 extends and gets stuck between the groove of the positioning pin 401 and the positioning slip ring 403. The positioning pin 401 is then locked on the positioning seat 402. Therefore, the lifting guide system 5 and the lifting platform 6 can be fixed on the transverse frame. After being locked and stabilized, the lifting power unit 2 can be moved horizontally to the upper part of the entrance / exit column that needs to be replaced. During unlocking, the lifting platform 6 needs to be raised further. The positioning pin 401 of the locking and positioning mechanism 4 on the lifting guide system 5 installed on the lifting platform 6 continues to penetrate deeper into the positioning seat 402. The spring pin 404 is pushed and retracted by the inclined surface of the positioning slip ring 403. After the spring pin 404 retracts, as the positioning pin 401 rises, the spring pin 404 will slide out to the lower part of the positioning slip ring 403. The unlocking sensor detects the unlocking completion signal and sends it to the control system. After the control system receives the unlocking signal, the lifting power unit 2 will descend, and the positioning pin 401 on the lifting platform 6 will move downward. The spring pin 404 pushes the positioning slip ring 403 upward into the upper groove of the positioning pin 401. As the positioning pin 401 continues to descend, the positioning slip ring 403 pushes the spring pin 404 to retract and slide to the upper part of the positioning pin 401, thus completing the unlocking. The lifting power unit 2 can then perform vertical lifting operations.It should be noted that the lifting power unit 2 of this utility model supports combined vertical lifting and horizontal lateral movement. However, in order to ensure equipment safety, vertical lifting and horizontal lateral movement cannot be carried out simultaneously. One action can only be carried out after the other action is completed. Moreover, the horizontal lateral movement is only carried out after receiving the instruction to change the entrance / exit, and the top of the lifting platform 6 is lifted and locked in place. It is only used when scheduling across regions.

[0028] like Figure 12 and Figure 13As shown, because the split comb frame of the lifting platform 6 has a certain thickness, in order to ensure the level of the entrance and exit surface, a pit is left at the lower level of the equipment's entrance and exit position for the lower part of the lifting platform 6. When the lifting platform 6 is lowered into place, its upper surface remains level with the ground, thus forming a smooth entry and exit channel. A pit is left in the middle of the lifting platform 6. In addition, the lifting platform 6 needs to exchange with the transverse moving platform 7 using combs. The spacing of the comb frame of the lifting platform 6 is relatively large. The small pit and the large gap of the comb frame will cause problems when vehicles enter and exit. To address this inconvenience, a special entrance / exit platform 9 was installed. Platform 9 is a rectangular structure. Unlike the transverse sliding platform 7, platform 9 lacks grooved tracks at its front and rear ends; instead, it has front and rear comb teeth 901 and 902 on both sides, identical in layout to those on the transverse sliding platform 7. The front and rear comb teeth 901 and 902 are of the same length and have the same spacing. These teeth correspond to the front and rear comb teeth of the lifting platform 6, alternating for vehicle exchange and parking. The middle section of platform 9 is covered with a patterned cover plate 903, which increases the coefficient of friction through raised textures, meeting the anti-slip requirements for pedestrians and vehicles, and facilitating vehicle movement. At the four corners of the lower part of platform 9, there are also fixed base plates 904 for installation. These base plates 904 have mounting holes, allowing platform 9 to be fixed to the garage pit using expansion bolts or other fasteners. The filling platform 9 has a 5mm thick rubber pad laid on the contact surface between its fixed base plate 904 and the foundation pit to eliminate installation gaps and buffer vibrations. The filling platform 9 can also be freely arranged and installed in the required position according to the needs of the entrance / exit, and fixed with bolts. During installation, the filling platform 9 is located in the center of the entrance / exit foundation pit, staggered with the lifting platform 6. Its upper surface is horizontal to the ground, and its vertical surface is staggered with the lifting platform 6. When the lifting platform 6 descends to its position, the filling platform 9 will be staggered with the lifting platform, and the foundation pit at the entrance / exit will be filled, minimizing the gaps between the teeth. This greatly improves the safety of vehicle storage and retrieval and personnel access. The staggered vertical design of the filling platform 9 and the lifting platform 6 essentially achieves foundation pit depth compensation through mechanical linkage. When the lifting platform 6 descends to the predetermined position, the horizontal plane of the filling platform 9 forms a continuous plane with the platform comb teeth, filling the pit drop problem caused by the lifting of the platform in traditional tower garages. Through the precise cooperation of the staggered structure, the gap between the comb teeth can be controlled to ≤30mm, which is far lower than the industry's common gap requirement of 50mm, referring to the GB / T 27545-2011 standard for mechanical parking equipment, effectively avoiding the risk of wheels or people stepping into empty spaces.

[0029] In summary, this utility model is a multi-entrance, power-assisted, mobile three-dimensional parking garage. The steel structure adopts a modular design, supporting rapid reconfiguration of the parking garage shape according to site characteristics, and can be combined into single-row, multi-column, and multi-level configurations. It employs a mobile lifting power unit 2 and track-changing guidance technology, sharing the lifting power unit 2. It can also automatically identify empty spaces and optimize the layout and position of the lifting channels according to real-time equipment needs. The mobile lifting power unit 2 enables cross-regional scheduling, and through the coordinated operation of the lifting power unit 2 and the lateral movement system, it can change the number and position of entrances and exits in real time, supporting 2-4 independent entrances and exits operating in parallel. It adopts a friction drive method using the grooved track of the lateral movement platform 7 tightly engaging the friction rollers 803, preventing derailment. It uses a fixed power supply, greatly improving the safety performance of power supply for high-rise parking and retrieval. The entrance filling platform 9 is designed and used, and through the staggered linkage design of the lifting platform 6 and the filling platform 9, it achieves pit filling and minimizes the gap between the comb teeth, reducing the original 100mm gap of the lifting comb teeth to 30mm, effectively avoiding the risk of wheels or personnel stepping into empty spaces. This utility model integrates the centralized drive concept of vertical lifting parking garages. Through a power resource sharing mechanism, it breaks through the energy efficiency bottleneck of traditional tower garages, effectively reducing the construction cost per parking space, reducing equipment failure rate, and significantly reducing maintenance costs.
