Description

Technical Field

[0001] The utility model relates to the field of auxiliary components for parking sheds, and particularly to a lifting frame of a 3D buried double-layer parking shed. Background Technique

[0002] At present, in view of the increasing number of civilian vehicles and private vehicles, as well as the situation of few parking spaces, difficult parking, and insufficient parking spaces, there are usually three solutions:

[0003] Solution 1: Build a large-scale three-dimensional parking garage. When this solution is actually implemented, the following problems will occur: 1. There are strict restrictions on the parked vehicles. Vehicles with a height exceeding 1.5 m and a weight exceeding 1.5 t cannot be used, and the practicality in actual application is relatively poor; 2. It is only applicable to commercial center areas and areas with relatively concentrated public parking garages, and is not suitable for ordinary families; 3. It is necessary to delimit a special construction site, with a long construction period, complex engineering technology, and great construction difficulty; 4. For community users, it is not applicable to residents whose residential areas are far from the parking garage; 5. It cannot be adapted to single-family villas, townhouse villas, and sites with limited space.

[0004] Solution 2: Increase ordinary ground parking lots and basement parking spaces. When this solution is actually implemented, the following problems will occur: 1. The space utilization rate is low, and the increased parking spaces are limited and cannot meet the current parking demand; 2. Adding parking spaces by the roadside will reduce the usable width of the road, slow down the traffic volume, and cause road congestion; 3. Adding parking spaces by the roadside will increase traffic accidents of vehicle scratching, and also increase the blind areas of vehicles in motion, increasing the risks of traffic accidents and accidents.

[0005] Solution 3: Increase basement parking lots. When this solution is actually implemented, the following problems will occur: 1. The basement needs to be planned synchronously with the initial construction of the community, and there is no room for renovation in the already built community; 2. Once the original basement building is built, it cannot be modified. Content of the Utility Model

[0006] The purpose of the utility model is to provide a lifting frame of a 3D buried double-layer parking shed to solve the above problems. Through the telescopic movement of the lifting cylinder of the lifting frame assembly and the meshing of the lifting chain around the lifting sprocket, the smooth lifting and lowering of the upper lifting cross beam and the lower lifting frame can be realized, ensuring that the parking platform assembly can move smoothly in the entire parking shed in a cycle, as will be elaborated below.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] The lifting frame of the 3D buried double-layer parking shed provided by the utility model comprises an end frame assembly, a parking platform assembly, a lower lifting frame, an upper lifting cross beam and a lifting cylinder. The lower lifting frame and the upper lifting cross beam are respectively arranged between the front and rear positions of the end frame assembly in the vertical direction. At the same time, the front and rear positions of the table top substrate of the parking platform assembly at the side part respectively span between the corresponding lower lifting frames on the same side, so as to drive the table top substrate at the side part to complete the lifting and lowering actions in the way of vertical lifting through the lower lifting frame.

[0009] Both sides of the bottom of the upper lifting cross beam are rotatably installed with lifting sprockets through sprocket mounting seats, and lifting chains are meshed and wound around the peripheries of the lifting sprockets. At the same time, the two ends of the lifting chains are respectively fixedly connected with the end frame cross beam at the bottom of the end frame assembly and the top of the lower lifting frame.

[0010] The end frame cross beam at the bottom of the end frame assembly is vertically fixed with the lifting cylinders at the positions beside the lifting chains, and the top ends of the hydraulic cylinders of the lifting cylinders are respectively fixedly connected with the bottom of the corresponding upper lifting cross beam.

[0011] Preferably, the lower lifting frame is an integral frame structure symmetrical up and down.

[0012] Preferably, a plurality of groups of longitudinal and transverse limit guiding bearings are rotatably installed at both ends of the lower lifting frame and the upper lifting cross beam, so as to limit and guide the lifting process of the parking platform assembly in the way of linear rolling of the limit guiding bearings along the limit guiding track of the end frame assembly.

[0013] Preferably, the hydraulic pipelines of the lifting cylinders at both sides are connected in series, so as to make the lifting cylinders run synchronously.

[0014] Preferably, the length of the lifting chain is at least twice the length of the lifting cylinder.

[0015] Using the lifting frame of the above-mentioned 3D buried double-layer parking shed, specifically in the setting process, due to the setting of the lifting frame assembly, and the upper lifting cross beam and the lower lifting frame of the lifting frame assembly are connected by the lifting chain, so that through the telescopic movement of the lifting cylinder of the lifting frame assembly and the meshing of the lifting chain around the lifting sprocket, the smooth lifting and lowering of the upper lifting cross beam and the lower lifting frame can be realized, ensuring that the parking platform assembly can smoothly carry out circular motion in the entire parking shed. Moreover, since the two ends of the lifting chain are respectively fixed to the end head frame assembly and the lower lifting frame, the differential motion of the upper lifting cross beam and the lower lifting frame during the lifting and lowering process can be realized through the setting of the lifting chain. Specifically, at both ends of the upper lifting cross beam and the lower lifting frame, since multiple groups of longitudinal and transverse limiting and guiding bearings are installed at both ends of the upper lifting cross beam and the lower lifting frame, the limiting and guiding of the parking platform assembly during the lifting and lowering process can be realized by the linear rolling of the limiting and guiding bearings along the limiting and guiding track of the end head frame assembly. And because the lower lifting frame adopts an integral frame structure design, the reliable stability of the lower lifting frame is ensured, preventing the parking platform assembly from tipping over during the lifting and lowering process. Further, the hydraulic pipelines of the multiple lifting cylinders of the lifting frame assembly are connected in series, ensuring the synchronous operation of the lifting cylinders at both sides and avoiding the tipping over of the parking platform assembly during the lifting and lowering process due to the asynchronous operation of the lifting cylinders.

[0016] The beneficial effects are as follows: 1. The utility model is provided with a lifting frame assembly, and the upper lifting cross beam and the lower lifting frame of the lifting frame assembly are connected by a lifting chain. In this way, through the telescopic movement of the lifting cylinder of the lifting frame assembly and the meshing of the lifting chain around the lifting sprocket, the smooth lifting and lowering of the upper lifting cross beam and the lower lifting frame can be realized, ensuring that the parking platform assembly can smoothly carry out circular motion in the entire parking shed. Moreover, since the two ends of the lifting chain are respectively fixed to the end head frame assembly and the lower lifting frame, the differential motion of the upper lifting cross beam and the lower lifting frame during the lifting and lowering process can be realized through the setting of the lifting chain;

[0017] 2. Multiple groups of longitudinal and transverse limiting and guiding bearings are installed at both ends of the upper lifting cross beam and the lower lifting frame. In this way, the limiting and guiding of the parking platform assembly during the lifting and lowering process can be realized by the linear rolling of the limiting and guiding bearings along the limiting and guiding track of the end head frame assembly. At the same time, because the lower lifting frame adopts an integral frame structure design, the reliable stability of the lower lifting frame is ensured, preventing the parking platform assembly from tipping over during the lifting and lowering process;

[0018] 3. The hydraulic pipelines of the multiple lifting cylinders of the lifting frame assembly are connected in series, ensuring the synchronous operation of the lifting cylinders on both sides and preventing the tilting of the parking platform assembly during the lifting and lowering processes due to the asynchronous operation of the lifting cylinders.

[0038] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope protected by the present utility model.

[0039] Referring to Figures 1 - 16 As shown, the present utility model provides a 3D buried double-layer parking shed, which includes an intermediate frame assembly 3, a parking platform assembly 4, an end frame assembly 1, a lifting frame assembly 2, a translation drive assembly 5, and a safety protection assembly 6. The intermediate frame assembly 3 is provided with parking platform assemblies 4 on the upper and lower layers to stably support and limit the parking platform assemblies 4 on the upper and lower layers through the intermediate frame assembly 3. Specifically for the intermediate frame assembly 3, the intermediate frame assembly 3 includes intermediate frame columns 302 and intermediate frame cross beams 301. There are multiple groups of intermediate frame columns 302 and intermediate frame cross beams 301. Each group of intermediate frame columns 302 consists of four columns and is respectively erected at the four corners of the same rectangle. Multiple intermediate frame cross beams 301 are horizontally fixed between the intermediate frame columns 302 on both sides to form a rectangular frame structure through each group of intermediate frame columns 302 and intermediate frame cross beams 301. With this setting, the intermediate frame cross beams 301 on the upper and lower layers of the intermediate frame assembly 3 can respectively stably support and limit the parking platform assemblies 4 on the upper and lower layers.

[0040] Referring to Figures 1 - 15As shown, specifically for the parking platform component 4, each parking platform component 4 includes a tabletop substrate 403. The tabletop substrates 403 are all horizontally placed between the intermediate frame crossbeams 301 at the front and rear positions, so as to stably support and limit the upper and lower tabletop substrates 403 respectively through the intermediate frame crossbeams 301 of the upper and lower layers. At the front and rear positions of the bottom surface of the tabletop substrate 403, a plurality of transverse movement track wheels 406 are rotatably connected through mounting brackets 405, so as to limit and guide the translation of the tabletop substrate 403 by linearly rolling the transverse movement track wheels 406 along the guide beam 304. At the front and rear positions of the tabletop substrate 403, multiple groups of outer chain limit buckles 407 and inner chain limit buckles 409 are evenly distributed and fixed at the positions corresponding to the front and rear of the mounting brackets 405 respectively, so as to drive the tabletop substrate 403 at the lower layer to perform translational movement by the way of being clamped by the cooperation of the inner chain limit buckle 409 and the translational drive component 5 at the lower position, and at the same time drive the tabletop substrate 403 at the lower layer to perform translational movement by the way of being clamped by the cooperation of the outer chain limit buckle 407 and the translational drive component 5 at the upper position. The function of such a setting is that the movement of the parked vehicle can be realized by the mutual cooperation of the parking platform component 4 with the translational drive component 5, the end frame component 1, the intermediate frame component and the lifting frame component 2, ensuring that multiple parking platform components 4 can successfully complete the cyclic parking operation of the vehicle.

[0041] See Figures 1 - 15As shown, end frame components 1 are combined and connected to both sides of the intermediate frame component 3, and lifting frame components 2 are installed inside the end frame components 1 to limit and guide the vertical lifting of the lifting frame components 2 through the end frame components 1, and at the same time to lift and lower the parking platform component 4 at the edge position through the lifting frame components 2. Specifically for the end frame component 1, the end frame component 1 includes end frame columns 101 and end frame cross beams 104. There are multiple groups of end frame columns 101 and end frame cross beams 104. Each group of end frame columns 101 consists of four columns and are respectively erected at the four corners of the same rectangle. Multiple end frame cross beams 104 are fixedly spanned between the end frame columns 101 at both sides to form a rectangular frame structure through the end frame columns 101 and end frame cross beams 104 at both sides. The end frame columns 101 at both sides close to each other are fixedly connected to the intermediate frame columns 302 at the outermost edge positions on both sides. Limit guiding tracks 102 are provided at the inner sides close to each other of the end frame columns 101 at the same side to limit and guide the vertical lifting of the lifting frame component 2 by linearly cooperating with the lifting frame component 2 through the limit guiding tracks 102. Motor mounting positions 103 for installing the translation drive component 5 are provided at the middle and bottom of the end frame columns 101. The purpose of such a setting is that the vertical lifting of the lifting frame component 2 can be limited and guided by linearly cooperating the limit guiding track 102 inside the end frame column 101 with the limit guiding bearing 207 of the lifting frame component 2, and at the same time, the hydraulic motor body 503 of the translation drive component 5 can be stably limited and fixed through the motor mounting position 103.

[0042] See Figures 1 - 15As shown in the figure, specifically for the lifting frame assembly 2, the lifting frame assembly 2 includes a lower lifting frame 202, an upper lifting crossbeam 201, and a lifting cylinder 204. The lower lifting frame 202 and the upper lifting crossbeam 201 are respectively arranged at the upper and lower positions between the front and rear positions of the end frame assembly 1. The front and rear positions of the tabletop substrate 403 at the side position respectively span between the corresponding lower lifting frames 202 on the same side, so as to drive the tabletop substrate 403 at the side position to complete the lifting and lowering actions by the vertical lifting of the lower lifting frame 202. On both sides of the bottom of the upper lifting crossbeam 201, lifting sprockets 205 are rotatably installed through sprocket mounting seats 203, and lifting chains 206 are meshed around the peripheries of the lifting sprockets 205. At the same time, both ends of the lifting chain 206 are fixedly connected to the end frame crossbeam 104 at the bottom of the end frame assembly 1 and the top of the lower lifting frame 202 respectively. Lifting cylinders 204 are vertically fixed at the positions of the end frame crossbeam 104 at the bottom of the end frame assembly 1 beside the lifting chain 206, and the top ends of the hydraulic cylinders of the lifting cylinders 204 are fixedly connected to the bottom of the corresponding upper lifting crossbeam 201. The advantage of such a setting is that through the telescopic movement of the lifting cylinder 204 of the lifting frame assembly 2 and the meshing of the lifting chain 206 around the lifting sprocket 205, the smooth lifting and lowering of the upper lifting crossbeam 201 and the lower lifting frame 202 can be realized, ensuring that the parking platform assembly 4 can smoothly perform circular motion in the entire parking shed. Moreover, since both ends of the lifting chain 206 are respectively fixed to the end frame assembly 1 and the lower lifting frame 202, the differential movement of the upper lifting crossbeam 201 and the lower lifting frame 202 during the lifting and lowering processes can be realized through the setting of the lifting chain 206.

[0043] See Figures 1 - 15As shown, a translation drive assembly 5 is installed between the end frame assemblies 1 at both sides to drive the parking platform assemblies 4 at the upper and lower levels to move translationally through the translation drive assembly 5 at the upper and lower positions. Specifically for the translation drive assembly 5, the translation drive assembly 5 includes a hydraulic motor body 503 and a translation rotating chain 504. The motor mounting positions 103 of the end frame columns 101 at both sides are respectively fixedly installed with hydraulic motor bodies 503, and the hydraulic motor bodies 503 at both sides are diagonally misaligned. The positions of the end frame columns 101 at both sides far from the hydraulic motor bodies 503 are respectively rotatably connected longitudinally with driven shafts 508 through bearing seats 509, and the driven shafts 508 are respectively level with the corresponding hydraulic motor bodies 503 in height. The drive shafts 502 of the hydraulic motor bodies 503 at the front and rear positions on the same side are coaxially fixed with driving sprockets 506, and the front and rear positions of the driven shafts 508 are coaxially fixed with driven sprockets 507. The corresponding driving sprockets 506 and driven sprockets 507 on both sides are peripherally engaged and wound with a full-circle translation rotating chain 504. The links of the translation rotating chains 504 at the upper and lower positions are evenly fixed with a plurality of chain buckles 505. The chain buckles 505 of the upper translation rotating chain 504 are vertically corresponding to the outer chain limit buckles 407 of the parking platform assembly 4 and can be cooperatively clamped with each other. At the same time, the chain buckles 505 of the lower translation rotating chain 504 are vertically corresponding to the inner chain limit buckles 409 of the parking platform assembly 4 and can be cooperatively clamped with each other. It is used to drive the table base plate 403 at the lower level to move translationally by the way of the inner chain limit buckle 409 being cooperatively clamped with the chain buckle 505 at the lower position, and at the same time, to drive the table base plate 403 at the lower level to move translationally by the way of the outer chain limit buckle 407 being cooperatively clamped with the chain buckle 505 at the upper position. With such a setting, the hydraulic motor body 503 of the translation drive assembly 5 can drive the translation rotating chain 504 to perform a cyclic motion, so that the parking platform assembly 4 at the lower level can be driven to move translationally by the way of the chain buckle 505 of the lower translation rotating chain 504 being clamped in the inner chain limit buckle 409 of the parking platform assembly 4, and at the same time, the parking platform assembly 4 at the upper level can be driven to move translationally by the way of the chain buckle 505 of the upper translation rotating chain 504 being clamped in the outer chain limit buckle 407 of the parking platform assembly 4.

[0044] See Figures 1 - 15As shown, a safety protection component 6 for performing safety monitoring during the entire parking process is installed on the intermediate frame component 3. Specifically for the safety protection component 6, the safety protection component 6 includes a signal lamp 601, a parking horn 602, a safety grating sensor 603, an infrared temperature sensor 604, a position switch 605, and a liquid level sensor 606. The signal lamp 601 and the parking horn 602 are respectively installed at the upper position of the intermediate frame component 3, and the safety grating sensor 603, the infrared temperature sensor 604, and the position switch 605 are respectively installed at the lower position of the intermediate frame component 3. The safety grating sensor 603, the infrared temperature sensor 604, and the liquid level sensor 606 are respectively installed at the lower position of the end frame component 1. The advantage of such a setting is that safety monitoring can be performed respectively before, during, and after the entire parking process, ensuring that the entire parking process can operate safely and reliably.

[0045] See Figures 1 - 15 As shown, the following optimizations are made to the intermediate frame component 3. Specifically, the upper part of the intermediate frame crossbeam 301 is a guiding beam 304 for guiding the translational movement of the parking platform component 4, and the lower part of the intermediate frame crossbeam 301 is a reinforcing beam 305 for enhancing the overall strength of the guiding beam 304. At the lower position, a roller mounting bracket 307 and a chain support plate 308 are respectively installed at the upper and lower positions on the inner sides of the intermediate frame crossbeams 301 close to each other. The roller mounting bracket 307 is rotatably connected with a plurality of chain rollers 306 evenly distributed in the transverse direction. In this way, it is convenient to support and limit the translational rotating chain 504 of the translational drive component 5 through the settings of the chain rollers 306 and the chain support plate 308, ensuring that the chain buckle 505 of the lower translational rotating chain 504 can be smoothly engaged and clamped with the inner chain limit buckle 409 of the parking platform component 4. Anti-cut arc plates 303 for preventing the cutting of automobile tires are integrally fixed on the edges of the intermediate frame crossbeams 301 at the front and rear positions close to each other. Preferably, the anti-cut arc plate 303 is an arc plate to prevent the vehicle from being cut and damaged by the sharp edges of the intermediate frame crossbeam 301 during the translational movement. Wear-resistant plates 309 are fixedly covered on the top surfaces of the chain support plates 308. The wear-resistant plates 309 are epoxy resin plates. With such a setting, first, it is convenient for the top surfaces of the chain support plates 308 to have a good and stable wear-resistant effect, and at the same time, it is convenient for the wear-resistant plates 309 to have a reliable and stable wear-resistant use ability.

[0046] See Figures 1 - 15As shown in the figure, the following optimizations are made to the parking platform assembly 4. Specifically, reinforcing ribs 408 with an integrated skeleton are welded to the bottom of the tabletop substrate 403 to facilitate the tabletop substrate 403 to have good and stable use strength. At the same time, the optional reinforcing ribs 408 are T-shaped steel bars and the reinforcing ribs 408 in the longitudinal position adopt a dislocation design. Preferably, the reinforcing ribs 408 are intensively strengthened at the positions corresponding to the automobile tires to facilitate the reliable stability of the tabletop substrate 403 during the process of parking the vehicle. A heightening channel 404 is fixedly covered along the longitudinal direction on one side of the top surface of the tabletop substrate 403. Preferably, the heightening channel 404 is arranged on the side close to the driver's seat. In this way, firstly, it is more convenient to get on and off the vehicle when parking the vehicle, and at the same time, it can also facilitate the driver to pass smoothly after getting off the vehicle. A flexible safety net 401 that is tilted and erected is installed on the rear part of the top surface of the tabletop substrate 403 through a net support 402. With such a setting, it is convenient to clearly indicate the parking in place by the way of the head or tail of the vehicle contacting the flexible safety net 401, ensuring that the driver can park the vehicle on the tabletop substrate 403 smoothly;

[0047] See Figures 1 - 15 As shown in the figure, the following optimizations are made to the end frame assembly 1. Specifically, the end frame column 101 is an H-shaped steel column, and the limit guiding track 102 corresponds to the inner channel of the end frame column 101, so that the limit guiding track 102 has good and reliable use effects. There are four motor mounting positions 103 on both sides, so that the appropriate number of hydraulic motor bodies 503 can be selected and installed according to actual use needs. Vertical limit guiding plates 107 are vertically extended and fixed at the inner edge positions where the end frame columns 101 on both sides are close to each other, so as to limit and guide the vertical lifting process of the parking platform assembly 4 through the limit guiding plates 107. The upper and lower parts of the end frame columns 101 on both sides that are close to each other and the middle frame column 302 at the nearest outermost edge position are fixedly connected together by the way of inserting and installing bolts. At the same time, the end frame columns 101 on both sides that are close to each other and the middle frame column 302 at the nearest outermost edge position are both vertically extended and fixed with extension connecting plates 106 at the middle section position, and the end frame columns 101 and the middle frame column 302 are both strengthened and fixedly connected by the way of inserting and installing bolts through the extension connecting plates 106. With such a setting, it is convenient for the end frame column 101 and the middle frame column 302 at the nearest outermost edge position to be stably fixedly connected together, and at the same time, the way of fixedly connecting through the extension connecting plate 106 can prevent the bolts from interfering with the smooth linear rolling of the limit guiding bearing 207 along the limit guiding track 102. Upper guide chain plates 105 and lower guide chain plates 108 for guiding the translation drive assembly 5 are respectively installed at the end positions of the end frame cross beam 104 at the middle position and the end frame cross beam 104 at the lower position. In this way, it is convenient to respectively constrain and guide the circumferential rotation of the translation rotating chain 504 through the upper guide chain plates 105 and the lower guide chain plates 108.

[0048] See Figures 1 - 15 As shown, the following optimizations are made to the lifting frame assembly 2. Specifically, the lower lifting frame 202 is an integrally formed frame structure that is symmetrical up and down, so as to ensure that the lower lifting frame 202 has a reliable stabilizing effect and prevent the parking platform assembly 4 from tipping over during the lifting and lowering processes. A plurality of longitudinal and transverse limiting and guiding bearings 207 are rotatably installed at both ends of the lower lifting frame 202 and the upper lifting cross beam 201, and are used to limit and guide the lifting process of the parking platform assembly 4 by linearly rolling the limiting and guiding bearings 207 along the limiting and guiding track 102. The hydraulic pipelines of the lifting cylinders 204 at both sides are connected in series, so as to make the lifting cylinders 204 operate synchronously, thereby avoiding the tipping over of the parking platform assembly 4 during the lifting and lowering processes due to the asynchronous operation of the lifting cylinders 204. The length of the lifting chain 206 is at least twice the length of the lifting cylinder 204, so as to facilitate the lifting chain 206 to have a set length that meets the use requirements.

[0049] See Figures 1 - 15 As shown, the following optimizations are made to the translation drive assembly 5. Specifically, a connecting shaft 501 is coaxially fixed between the drive shafts 502 of the hydraulic motor bodies 503 at the front and rear positions on the same side, so as to make the drive shafts 502 at the front and rear positions rotate synchronously, which is beneficial to improving the stability of the translation drive assembly 5 during operation. The hydraulic motor bodies 503 are all self-locking hydraulic motors, so as to prevent the parking platform assembly 4 from accidentally moving when the parking platform assembly 4 is driven to move in place. The transmission ratio of the driving sprocket 506 and the driven sprocket 507 is 1. With such a setting, it is convenient for the driving sprocket 506 and the driven sprocket 507 to have good transmission smoothness during the process of driving the translation rotating chain 504 to rotate.

[0050] See Figures 1 - 15As shown, the following optimizations are made to the safety protection component 6. Specifically, the signal lamp 601 and the parking horn 602 are respectively installed on the middle frame cross beam 301 at the front position of the middle frame component 3 to give a warning before parking, so as to effectively alert external personnel before parking preparation. The safety grating sensor 603, the infrared temperature sensor 604 and the position switch 605 at the lower position of the middle frame component 3 are respectively installed in the middle and lower parts of the middle frame column 302 to immediately stop the horizontal movement of the parking platform component 4 when detecting the movement of vehicles, personnel and pets. Specifically, when the parking platform starts to operate and a vehicle, a person or a pet passes by or is getting on or off the parking platform, at this time, the safety grating sensor 603, the infrared temperature sensor 604 and the position switch 605 receive signals and stop running in time to prevent the vehicle or personnel from being dragged or squeezed and damaged or injured. The safety grating sensor 603, the infrared temperature sensor 604 and the liquid level sensor 606 at the lower position of the end frame component 1 are respectively installed in the middle and lower parts of the end frame column 101 to immediately stop the lifting movement of the parking platform component 4 when detecting the movement of personnel and pets getting on and off the vehicle. Specifically, when a person or a pet accidentally enters the end frame component 1 when getting on or off the vehicle, and when there are items, personnel or pets staying on the lower plane of the end frame component 1 when the parking platform component 4 descends, at this time, the safety grating sensor 603 and the infrared temperature sensor 604 receive signals and stop descending in time to prevent the items, personnel or pets staying on the lower plane of the end frame component 1 from being squeezed and damaged or injured. Further optionally, the liquid level sensor 606 is non-contact, and the liquid level sensor 606 is installed on the bottom surface of the end frame cross beam 104 at the bottom position to give an alarm in time when there is accumulated water at the bottom of the end frame component 1. Specifically, when there is accumulated water in the foundation of the lower plane of the end frame component 1, the liquid level sensor 606 gives an alarm in time to remind the operator to deal with the accumulated water in time, or gives an alarm in time to remind the vehicle owner that there is accumulated water in the lower layer, so as to facilitate a timely response and quickly take out and move the vehicle on the lower parking platform component 4 or lift it to the upper parking platform component 4 to prevent the vehicle from being soaked in water.

[0051] With the above structure, specifically in the process of setting, since there is a double-layer parking platform component 4, then in the case of inconvenient parking lot area, the parking capacity can be doubled through the double-layer parking platform component 4. At the same time, it does not occupy new bottom space during setting, and only needs to be re-transformed on the original parking lot to complete the layout. Moreover, the parking platform component 4 has no strict height and weight restrictions on parked vehicles, and the scope of use of parked vehicles is wide and the applicability is good. Specifically, a double-layer circular parking shed is formed by the middle frame component 3, the lifting frame component 2, the end frame component 1, the parking platform component 4 and the translation drive component 5. The structure is simple and easy to operate. At the same time, it is convenient to flexibly adjust the installation method according to the actual situation of the installation site, has low requirements for the installation site, can be installed in a buried manner, or can be directly installed on the ground, has a short construction period, low comprehensive construction cost, strong installation adaptability, and large transformation space. Specifically, in the setting of the middle frame component 3, since the middle frame component 3 can be provided with multiple entrances and exits to enable multiple cars to enter and exit at the same time, or can be set as a fixed one entrance and exit according to the site needs, the setting method of the entrance and exit is flexible, which facilitates the entry and exit of vehicles, saves parking time and is beneficial to improving parking efficiency. Specifically, for the translation drive component 5, since there is a translation drive component 5, the hydraulic motor body 503 of the translation drive component 5 can drive the translation rotating chain 504 to perform a circular motion, so that the parking platform component 4 at the lower layer can be driven to perform translational movement by the chain buckle 505 of the lower translation rotating chain 504 being stuck in the inner chain limit buckle 409 of the parking platform component 4, and at the same time, the parking platform component 4 at the upper layer can be driven to perform translational movement by the chain buckle 505 of the upper translation rotating chain 504 being stuck in the outer chain limit buckle 407 of the parking platform component 4. The translational drive method for the parking platform component 4 is reliable and easy to implement, and then it is convenient for the parking platform component 4 to drive the vehicle to perform translational movement. Specifically, for the end frame component 1, since there is an end frame component 1, the vertical lifting of the lifting frame component 2 can be limited and guided by the linear cooperation of the limit guiding track 102 inside the end frame column 101 and the limit guiding bearing 207 of the lifting frame component 2. At the same time, the hydraulic motor body 503 of the translation drive component 5 can be stably limited and fixed through the motor mounting position 103 to prevent the hydraulic motor body 503 of the translation drive component 5 from moving randomly. Moreover, the vertical lifting of the parking platform component 4 can be limited and guided by the limit guiding plate 107 at the edge of the end frame column 101 to prevent the parking platform component 4 from slipping horizontally from the lifting frame component 2 during the vertical lifting process with the lifting frame component 2. Further specifically for the middle frame component 3, since there is a middle frame component 3, the middle frame cross beams 301 on the upper and lower layers of the middle frame component 3 can respectively stably support and limit the parking platform components 4 on the upper and lower layers, which not only ensures that the parking platform components 4 on the upper and lower layers can park vehicles at the same time,Meanwhile, it also ensures the smooth operation of the parking platform components 4 on the upper and lower layers. Further, since chain carrier wheels 306 and chain carrier plates 308 are provided at the bottom of the intermediate frame component 3, the translation drive chain 504 of the translation drive component 5 can be supported and limited through the settings of the chain carrier wheels 306 and the chain carrier plates 308, ensuring that the chain fasteners 505 of the lower translation drive chain 504 can be smoothly engaged and clamped with the inner chain limit buckles 409 of the parking platform component 4. Specifically for the lifting frame component 2, due to the provision of the lifting frame component 2, and the upper lifting cross beam 201 and the lower lifting frame 202 of the lifting frame component 2 are connected by a lifting chain 206, the smooth lifting and lowering of the upper lifting cross beam 201 and the lower lifting frame 202 can be achieved through the telescopic movement of the lifting cylinders 204 of the lifting frame component 2 and the meshing of the lifting chain 206 around the lifting sprockets 205, ensuring that the parking platform component 4 can smoothly perform circular motion in the entire parking shed. Moreover, since both ends of the lifting chain 206 are respectively fixed to the end frame component 1 and the lower lifting frame 202, the differential motion of the upper lifting cross beam 201 and the lower lifting frame 202 during the lifting and lowering processes can be achieved through the setting of the lifting chain 206. Specifically for the positions at both ends of the upper lifting cross beam 201 and the lower lifting frame 202, since multiple longitudinal and transverse limit guiding bearings 207 are installed at the positions at both ends of the upper lifting cross beam 201 and the lower lifting frame 202, the limit guiding during the lifting and lowering processes of the parking platform component 4 can be achieved through the linear rolling of the limit guiding bearings 207 along the limit guiding track 102 of the end frame component 1. And since the lower lifting frame 202 adopts an integral frame structure design, it further ensures the reliable stability of the lower lifting frame 202, preventing the parking platform component 4 from overturning during the lifting and lowering processes. Further, the hydraulic pipelines of the multiple lifting cylinders 204 of the lifting frame component 2 are connected in series, ensuring the synchronous operation of the lifting cylinders 204 at both positions and avoiding the overturning of the parking platform component 4 during the lifting and lowering processes due to the asynchronous operation of the lifting cylinders. Specifically for the parking platform component 4, due to the provision of the parking platform component 4, the movement of the parked vehicle can be achieved through the mutual cooperation of the parking platform component 4 with the translation drive component 5, the end frame component 1, the intermediate frame component 3, and the lifting frame component 2, ensuring that multiple parking platform components 4 can smoothly complete the circular parking operation of the vehicle. More specifically, reinforcing ribs 408 with an integral skeleton are welded at the bottom of the tabletop substrate 403 of the parking platform component 4, and the reinforcing ribs 408 in the longitudinal position are designed with offsets, thus ensuring the firmness and durability of the tabletop substrate 403. At the same time, a raised channel 404 is covered and fixed on one side of the top surface of the tabletop substrate 403, and through the setting of the raised channel 404, it is more convenient to get on and off the vehicle when parking the vehicle, and it can also facilitate the driver to pass smoothly after getting off the vehicle. Specifically for the safety protection component 6, due to the provision of the safety protection component 6,Moreover, the safety protection component 6 includes a signal lamp 601 and a parking horn 602 installed at the upper position of the intermediate frame component 3, a safety grating sensor 603, an infrared temperature sensor 604 and a position switch 605 installed at the lower position of the intermediate frame component 3, and a safety grating sensor 603, an infrared temperature sensor 604 and a liquid level sensor 606 installed at the lower position of the end frame component 1, so as to be able to perform safety monitoring before, during and after the entire parking process respectively, ensuring that the entire parking process can operate safely and reliably.
