Description

Technical Field

[0001] The utility model relates to the field of auxiliary components for parking sheds, and particularly to an intermediate 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 implementing this solution, the following problems will occur: 1. There are strict restrictions on the parked vehicles. Vehicles with a height exceeding 1.5m and a weight exceeding 1.5t cannot be used, and the practicality in actual applications 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 dedicated construction site, with a long construction period, complex engineering technology, and great construction difficulty; 4. For community users, it is not applicable to residents in residential areas 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 implementing this solution, the following problems will occur: 1. The space utilization rate is low, and the increased parking spaces are limited, unable to meet the current parking demand; 2. Adding parking spaces on the roadside will reduce the usable width of the road, slow down the traffic volume, and cause road congestion; 3. Adding parking spaces on the roadside will increase traffic accidents of vehicle scratches, and also increase the blind spots of vehicles in motion, increasing the risks of traffic accidents and traffic accidents.

[0005] Solution 3: Increase basement parking lots. When implementing this solution, 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 existing communities; 2. Once the original basement building is built, it cannot be modified. Content of the Utility Model

[0006] The purpose of the present utility model is to provide an intermediate frame of a 3D buried double-layer parking shed to solve the above problems. The intermediate frame assembly can be provided with multiple entrances and exits to enable multiple cars to enter and exit simultaneously, or can be set as a fixed single entrance and exit according to the needs of the site. The setting method of the entrance and exit is flexible, which facilitates the entry and exit of vehicles, saves parking time, and is conducive to improving parking efficiency. Details are described below.

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

[0008] The middle frame of the 3D in-ground double-layer parking shed provided by the utility model comprises middle frame columns, middle frame cross beams and a parking platform assembly. A plurality of groups of the middle frame columns and the middle frame cross beams are provided. Each group of the middle frame columns consists of four columns which are respectively erected at the four corners of the same rectangle. A plurality of the middle frame cross beams are fixedly spanned between the middle frame columns at both side positions to form a rectangular frame structure through the middle frame columns and the middle frame cross beams of each group.

[0009] Preferably, the upper part of the middle frame cross beam is a guiding beam for guiding the translational movement of the parking platform assembly, and the lower part of the middle frame cross beam is a reinforcing beam for enhancing the overall strength of the guiding beam.

[0010] Preferably, a roller mounting bracket and a chain supporting plate are respectively installed at the upper and lower positions on the inner sides of the middle frame cross beams at the lower positions close to each other. A plurality of chain supporting rollers evenly distributed in the transverse direction are rotatably connected to the roller mounting bracket.

[0011] Preferably, anti-cut arc plates for preventing the cutting of automobile tires are integrally fixed at the edges of the middle frame cross beams at the front and rear positions close to each other.

[0012] Preferably, wear-resistant plates are fixedly covered on the top surfaces of the chain supporting plates.

[0013] Preferably, the wear-resistant plate is an epoxy resin plate.

[0014] When the above-mentioned middle frame of the 3D in-ground double-layer parking shed is adopted, specifically in the setting process, since the middle frame assembly can be provided with multiple entrances and exits to allow multiple automobiles to enter and exit simultaneously, or can be set as a fixed single entrance and exit according to the site requirements, the setting method of the entrances and exits is flexible, which facilitates the entry and exit of vehicles, saves parking time and is beneficial to improving the parking efficiency. At the same time, the middle frame cross beams of the upper and lower layers of the middle frame assembly can respectively stably support and limit the parking platform assemblies of the upper and lower layers, which not only ensures that the parking platform assemblies of the upper and lower layers can park vehicles simultaneously, but also ensures that the parking platform assemblies of the upper and lower layers can operate smoothly. Further, since the chain supporting rollers and the chain supporting plates are arranged at the bottom of the middle frame assembly, the translational rotating chain of the translational driving assembly can be supported and limited through the arrangement of the chain supporting rollers and the chain supporting plates, ensuring that the chain buckle of the lower translational rotating chain can be smoothly engaged and clamped with the inner chain limiting buckle of the parking platform assembly.

[0015] The beneficial effects are as follows: 1. The middle frame assembly of the utility model can be provided with multiple entrances and exits to allow multiple automobiles to enter and exit simultaneously, or can be set as a fixed single entrance and exit according to the site requirements. The setting method of the entrances and exits is flexible, which facilitates the entry and exit of vehicles, saves parking time and is beneficial to improving the parking efficiency;

[0016] 2. The middle frame crossbeams on the upper and lower layers of the middle frame assembly can respectively provide stable support and limit for the parking platform assemblies on the upper and lower layers, which not only ensures that the parking platform assemblies on the upper and lower layers can park vehicles simultaneously, but also ensures that the parking platform assemblies on the upper and lower layers can operate smoothly.

[0017] 3. Chain carrier wheels and chain carrier plates are provided at the bottom of the middle frame assembly. By means of the chain carrier wheels and chain carrier plates, the translation rotating chain of the translation drive assembly can be supported and limited, ensuring that the chain buckle of the lower translation rotating chain can be smoothly engaged and locked with the inner chain limit buckle of the parking platform assembly.

Detailed implementation manners

[0037] 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. Apparently, the described embodiments are only a part rather than all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0038] See Figures 1 - 16As shown in the figure, the present utility model provides a 3D underground 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, and is used 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 has four columns and are respectively erected at the four corners of the same rectangle. And multiple intermediate frame cross beams 301 are fixedly spanned between the intermediate frame columns 302 at both side positions, so as to form a rectangular frame structure through each group of intermediate frame columns 302 and intermediate frame cross beams 301. In this way, 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.

[0039] See Figures 1 - 15 As shown in the figure, specifically for the parking platform assembly 4, the parking platform assemblies 4 each include a table top substrate 403. The table top substrates 403 are all horizontally placed between the intermediate frame cross beams 301 at the front and rear positions, and are used to stably support and limit the table top substrates 403 on the upper and lower layers through the intermediate frame cross beams 301 on the upper and lower layers respectively. A plurality of transverse movement track wheels 406 are rotatably connected to the front and rear positions of the bottom surface of the table top substrate 403 through mounting brackets 405, and are used to limit and guide the translation of the table top substrate 403 by linearly rolling the transverse movement track wheels 406 along the guide beam 304. A plurality of outer chain limit buckles 407 and inner chain limit buckles 409 are evenly distributed and fixed at the front and rear positions of the table top substrate 403 corresponding to the front and rear of the mounting brackets 405 respectively. The inner chain limit buckles 409 are used to drive the table top substrate 403 at the lower layer to perform translational movement by cooperating with the translation drive assembly 5 at the lower position, and at the same time, the outer chain limit buckles 407 are used to drive the table top substrate 403 at the lower layer to perform translational movement by cooperating with the translation drive assembly 5 at the upper position. The function of this setting is that the movement of the parked vehicle can be realized by the cooperation of the parking platform assembly 4 with the translation drive assembly 5, the end frame assembly 1, the intermediate frame assembly and the lifting frame assembly 2, ensuring that multiple parking platform assemblies 4 can successfully complete the cyclic parking operation of the vehicle.

[0040] 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 fixed across between the end frame columns 101 on both sides to form a rectangular frame structure through the end frame columns 101 and end frame cross beams 104 on both sides. The end frame columns 101 on both sides close to each other are fixedly connected to the intermediate frame columns 302 at the outermost edge positions on both sides. Limiting and guiding tracks 102 are provided at the inner sides close to each other of the end frame columns 101 on the same side to limit and guide the vertical lifting of the lifting frame components 2 by linearly cooperating with the lifting frame components 2 through the limiting and 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 components 2 can be limited and guided by linearly cooperating the limiting and guiding tracks 102 inside the end frame columns 101 with the limiting and guiding bearings 207 of the lifting frame components 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 positions 103.

[0041] See Figures 1 - 15As shown, 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. A lower lifting frame 202 and an upper lifting crossbeam 201 are respectively arranged at the upper and lower positions between the front and rear positions of the end head frame assembly 1. The front and rear positions of the table top substrate 403 at the edge position straddle between the corresponding lower lifting frames 202 on the same side, so as to drive the table top substrate 403 at the edge position to complete the lifting and lowering actions by the vertical lifting of the lower lifting frame 202. Both sides of the bottom of the upper lifting crossbeam 201 are rotatably installed with lifting sprockets 205 through sprocket mounting seats 203, and the peripheries of the lifting sprockets 205 are all meshed and bypassed by lifting chains 206. At the same time, both ends of the lifting chain 206 are fixedly connected to the end head frame crossbeam 104 at the bottom of the end head 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 head frame crossbeam 104 at the bottom of the end head 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 movement in the entire parking shed. Moreover, since both ends of the lifting chain 206 are respectively fixed to the end head 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.

[0042] 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 horizontally 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 the hydraulic motor body 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 body 503 are respectively rotatably connected with a driven shaft 508 longitudinally through a bearing seat 509, and the driven shafts 508 are respectively flush with the hydraulic motor body 503 at the corresponding 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 a driving sprocket 506, and the front and rear positions of the driven shaft 508 are coaxially fixed with a driven sprocket 507. A complete translation rotating chain 504 is meshed and wound around the corresponding driving sprocket 506 and driven sprocket 507 at both sides. A plurality of chain buckles 505 are evenly fixed on the links of the translation rotating chains 504 at the upper and lower positions. 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 engaged and locked 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 engaged and locked with each other. It is used to drive the table substrate 403 at the lower level to move horizontally by the way of the inner chain limit buckle 409 being engaged and locked with the chain buckle 505 at the lower position, and at the same time, to drive the table substrate 403 at the lower level to move horizontally by the way of the outer chain limit buckle 407 being engaged and locked 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 make a circular motion. Thus, the parking platform assembly 4 at the lower level can be driven to move horizontally 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 assembly 4, and at the same time, the parking platform assembly 4 at the upper level can be driven to move horizontally 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 assembly 4.

[0043] See Figures 1 - 15As shown in the figure, a safety protection component 6 for 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 carried out respectively before, during, and after the parking process of the entire parking process, ensuring that the entire parking process can operate safely and reliably.

[0044] See Figures 1 - 15 As shown in the figure, 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 upper and lower positions on the inner sides close to each other of the intermediate frame crossbeam 301 at the lower position, a carrier roller mounting bracket 307 and a chain carrier plate 308 are respectively installed. The carrier roller mounting bracket 307 is rotatably connected with a plurality of chain carrier rollers 306 evenly distributed in the transverse direction. In this way, it is convenient to support and limit the translational rotation chain 504 of the translational drive component 5 through the settings of the chain carrier rollers 306 and the chain carrier plate 308, ensuring that the chain buckle 505 of the lower translational rotation 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 close to each other of the intermediate frame crossbeams 301 at the front and rear positions. 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 carrier 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 carrier plates 308 to have good and stable wear resistance, and at the same time, it is convenient for the wear-resistant plates 309 to have reliable and stable wear resistance and serviceability.

[0045] See Figures 1 - 15As shown, the following optimizations are made to the parking platform component 4. Specifically, reinforcing ribs 408 with an integral skeleton are welded to the bottom of the tabletop substrate 403, so that the tabletop substrate 403 has good and stable service strength. At the same time, the optional reinforcing ribs 408 are T-shaped steel bars, and the reinforcing ribs 408 in the longitudinal direction are designed with staggering. Preferably, the reinforcing ribs 408 are intensively strengthened at the positions corresponding to the automobile tires, so that the tabletop substrate 403 is reliable and stable during the process of parking a 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, and at the same time, it is also convenient for 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 that the parking is in place by touching the flexible safety net 401 with the front or rear of the vehicle, ensuring that the driver can successfully park the vehicle on the tabletop substrate 403;

[0046] See Figures 1 - 15 As shown, the following optimizations are made to the end frame component 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 service 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 usage needs. Vertical limit guiding plates 107 are fixedly extended at the inner edges of the end frame columns 101 on both sides that are close to each other, so as to limit and guide the vertical lifting process of the parking platform component 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 means of inserting and installing bolts. At the same time, extended connecting plates 106 are erected and extended at the middle positions 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. The end frame columns 101 and the middle frame column 302 are strengthened and fixedly connected by means of inserting and installing bolts through the extended 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 extended connecting plates 106 can prevent the bolts from interfering with the smooth linear rolling of the limit guiding bearings 207 along the limit guiding track 102. Upper guide chain plates 105 and lower guide chain plates 108 for guiding the translation drive component 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.

[0047] 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 means of linear rolling of the limiting and guiding bearings 207 along the limiting and guiding track 102. The hydraulic pipelines of the lifting cylinders 204 on 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 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 setting length of the lifting chain 206 to meet the usage requirements.

[0048] 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 rotation chain 504 to rotate.

[0049] See Figures 1 - 15As shown in the figure, 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 part 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 translational 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 there are vehicles, personnel or pets passing by or getting on and 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 vehicles or personnel from being dragged or squeezed, resulting in damage or personal injury. The safety grating sensor 603, the infrared temperature sensor 604 and the liquid level sensor 606 at the lower part 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, because when personnel or pets get on and off the vehicle, they accidentally break into the end frame component 1. When the parking platform component 4 descends, there are items, personnel or pets staying on the lower plane of the end frame component 1. 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, resulting in damage or personal injury. Further optionally, the liquid level sensor 606 is non-contact. 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 water accumulation at the bottom of the end frame component 1. Specifically, when there is water accumulation 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 water accumulation in time, or gives an alarm in time to remind the vehicle owner that there is water accumulation in the lower layer, so as to facilitate 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.

[0050] With the above structure, specifically in the process of setting, due to the provision of a double-layer parking platform assembly 4, when the parking lot area is inconvenient, the parking capacity can be doubled through the double-layer parking platform assembly 4, and at the same time, it does not occupy new bottom space during setting, and the layout can be completed only after a secondary transformation of the original parking lot. Moreover, the parking platform assembly 4 has no strict height and weight restrictions on parked vehicles, and the use range of parked vehicles is wide and the applicability is good. Specifically, a double-layer circulating structure parking shed is formed by the middle frame assembly 3, the lifting frame assembly 2, the end frame assembly 1, the parking platform assembly 4 and the translation drive assembly 5. The structure is simple and easy to operate, and the installation can be flexibly adjusted according to the actual situation of the installation site. The method has low requirements for the installation site, can be installed underground or directly 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 intermediate frame component 3, since the intermediate frame component 3 can be provided with multiple entrances and exits to enable multiple vehicles to enter and exit at the same time, it can also be provided as a fixed entrance and exit according to the needs of the site. The setting method of the entrance and exit is flexible, which facilitates the entry and exit of vehicles, saves parking time and is conducive to improving parking efficiency. Specifically, as for the translation drive component 5, since the translation drive component 5 is provided, the hydraulic motor body 503 of the translation drive component 5 can drive the translation rotation chain 504 to perform a circular motion, thereby passing through the chain buckle 505 of the lower translation rotation chain 504 The inner chain limit buckle 409 stuck in the parking platform assembly 4 can drive the parking platform assembly 4 at the lower position to move in translation. At the same time, the chain buckle 505 of the upper translational rotating chain 504 is stuck in the outer chain limit buckle 407 of the parking platform assembly 4, which can drive the parking platform assembly 4 at the upper position to move in translation. The translation drive method of the parking platform assembly 4 is reliable and easy to implement, which makes it convenient for the parking platform assembly 4 to drive the vehicle to move in translation. As for the end frame assembly 1, since the end frame assembly 1 is provided, the vertical lifting of the lifting frame assembly 2 can be limited and guided by the linear cooperation between the limit guide rail 102 on the inner side of the end frame column 101 and the limit guide bearing 207 of the lifting frame assembly 2. At the same time, the motor mounting position 103 can be used to stably limit and fix the hydraulic motor body 503 of the translation drive assembly 5 to prevent the hydraulic motor body 503 of the translation drive assembly 5 from moving around, and the limiting guide plate 107 at the edge of the end frame column 101 can limit and guide the vertical lifting of the parking platform assembly 4 to prevent the parking platform assembly 4 from sliding off the lifting frame assembly 2 laterally during the vertical lifting of the lifting frame assembly 2. More specifically, the intermediate frame assembly 3 is provided, so that the intermediate frame crossbeams 301 of the upper and lower layers of the intermediate frame assembly 3 can respectively support and limit the upper and lower parking platform assemblies 4 stably, which ensures that the upper and lower parking platform assemblies 4 can park vehicles at the same time.Meanwhile, it also ensures the smooth operation of the upper and lower parking platform components 4. 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 buckle 505 of the lower translation drive chain 504 can be smoothly engaged and clamped with the inner chain limiting buckle 409 of the parking platform component 4. Specifically for the lifting frame component 2, since the lifting frame component 2 is provided, 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 cylinder 204 of the lifting frame component 2 and the meshing of the lifting chain 206 around the lifting sprocket 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, 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 two ends of the upper lifting cross beam 201 and the lower lifting frame 202, since multiple longitudinal and transverse limiting and guiding bearings 207 are installed at both ends of the upper lifting cross beam 201 and the lower lifting frame 202, the limiting and guiding of the parking platform component 4 during the lifting process can be achieved through the linear rolling of the limiting and guiding bearings 207 along the limiting and guiding track 102 of the end frame component 1. And since the lower lifting frame 202 adopts an integral frame structure design, it ensures that the lower lifting frame 202 has a reliable stabilizing effect, preventing the parking platform component 4 from tipping over 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 sides and avoiding the tipping over 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, since the parking platform component 4 is provided, 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 direction are designed with staggering, ensuring the firmness and durability of the tabletop substrate 403. At the same time, a raised passage 404 is covered and fixed on one side of the top surface of the tabletop substrate 403, and through the setting of the raised passage 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, since the safety protection component 6 is provided,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 respectively before, during, and after the parking process of the entire parking process, ensuring that the entire parking process can operate safely and reliably.
