Description

Technical Field

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

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

[0003] Solution 1: Construct a large-scale three-dimensional parking garage. When actually implementing this solution, 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. A dedicated construction site needs to be demarcated, the construction period is long, the engineering technology is complex, and the construction difficulty is relatively large; 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 actually implementing this solution, 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 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 actually 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 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 an end frame of a 3D buried double-layer parking shed to solve the above problems. The vertical lifting of the lifting frame assembly can be limited and guided by the linear cooperation between the limit guiding track inside the end frame column and the limit guiding bearing of the lifting frame assembly, as described in detail below.

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

[0008] The end frame of the 3D buried double-layer parking shed provided by the present utility model includes end frame columns, end frame cross beams, intermediate frame components, lifting frame components, translation drive components and parking platform components. There are multiple groups of the end frame columns and the end frame cross beams. Each group of the end frame columns consists of four columns and are respectively erected at the four corners of the same rectangle. Multiple end frame cross beams are fixedly spanned between the end frame columns at both sides to form a rectangular frame structure through the end frame columns and the end frame cross beams at both sides. The end frame columns at both sides close to each other are fixedly connected to the intermediate frame columns of the intermediate frame components at the outermost positions on both sides;

[0009] Limit guiding tracks are arranged at the inner sides close to each other of the end frame columns at the same side to limit and guide the vertical lifting of the lifting frame component by linearly cooperating the limit guiding tracks with the lifting frame component;

[0010] Motor mounting positions for mounting the translation drive component are arranged at the middle and bottom of the end frame columns.

[0011] Preferably, the end frame columns are H-shaped steel columns, and the limit guiding tracks correspond to the inner channels of the end frame columns.

[0012] Preferably, there are four motor mounting positions at both sides.

[0013] Preferably, limit guiding plates are vertically and fixedly extended at the inner edge positions close to each other of the end frame columns at the same side to limit and guide the vertical lifting process of the parking platform component through the limit guiding plates.

[0014] Preferably, the upper and lower parts of the end frame columns at both sides close to each other and the intermediate frame columns at the outermost positions close to them are fixedly connected by inserting and installing bolts. At the same time, extension connecting plates are erected and extended and fixed at the middle sections of the end frame columns at both sides close to each other and the intermediate frame columns at the outermost positions close to them, and the end frame columns and the intermediate frame columns are further fixedly connected by inserting and installing bolts through the extension connecting plates.

[0015] Preferably, upper guide chain plates and lower guide chain plates for guiding the translation drive component are respectively installed at the end positions of the end frame cross beams at the middle position and the end frame cross beams at the lower position.

[0016] Using the end frame of the above-mentioned 3D buried double-layer parking shed, specifically in the setting process, due to the setting of the end frame assembly, the vertical lifting of the lifting frame assembly can be limited and guided by the linear cooperation of the limit guiding track inside the end frame column and the limit guiding bearing of the lifting frame assembly. At the same time, the hydraulic motor body of the translation drive assembly can be stably limited and fixed through the motor mounting position, preventing the hydraulic motor body of the translation drive assembly from moving randomly. Moreover, the vertical lifting of the parking platform assembly can be limited and guided by the limit guiding plate at the edge position of the end frame column, avoiding the parking platform assembly from slipping horizontally off the lifting frame assembly during the vertical lifting process with the lifting frame assembly.

[0017] The beneficial effects are as follows: The utility model is provided with an end frame assembly. In this way, the vertical lifting of the lifting frame assembly can be limited and guided by the linear cooperation of the limit guiding track inside the end frame column and the limit guiding bearing of the lifting frame assembly. At the same time, the hydraulic motor body of the translation drive assembly can be stably limited and fixed through the motor mounting position, preventing the hydraulic motor body of the translation drive assembly from moving randomly. Moreover, the vertical lifting of the parking platform assembly can be limited and guided by the limit guiding plate at the edge position of the end frame column, avoiding the parking platform assembly from slipping horizontally off the lifting frame assembly during the vertical lifting process with the lifting frame assembly.

[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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. 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 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, so as 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 is 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 sides, 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, each parking platform assembly 4 includes 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, so as 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. Multiple 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, so as to limit and guide the translation of the table top substrate 403 by the linear rolling of the transverse movement track wheels 406 along the guide beam 304. Multiple groups of outer chain limit buckles 407 and inner chain limit buckles 409 are evenly 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, so as to drive the table top substrate 403 at the lower layer to perform translational movement by the way of being clamped in cooperation with the translation drive assembly 5 at the lower position by the inner chain limit buckle 409, and at the same time drive the table top substrate 403 at the lower layer to perform translational movement by the way of being clamped in cooperation with the translation drive assembly 5 at the upper position by the outer chain limit buckle 407. 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 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 middle 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. At the same time, the parking platform components 4 at the edge positions are lifted and lowered through the lifting frame components 2. Specifically for the end frame components 1, each 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 is 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 middle frame columns 302 at the outermost edge positions on both sides. Limiting and guiding tracks 102 are provided at the inner sides of the end frame columns 101 at the same side close to each other 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 components 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. 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. 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 head 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 means of 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 mounts 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 respectively 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. The end head frame crossbeams 104 at the bottom of the end head frame assembly 1 are all vertically fixed with lifting cylinders 204 at the positions beside the lifting chain 206, and the top ends of the hydraulic cylinders of the lifting cylinders 204 are all fixedly connected to the bottom of the corresponding upper lifting crossbeam 201. The advantage of such a setting is that the smooth lifting and lowering of the upper lifting crossbeam 201 and the lower lifting frame 202 can be realized 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, 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 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 in the figure, 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 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 away from the hydraulic motor bodies 503 are respectively rotatably connected with driven shafts 508 longitudinally through bearing seats 509, and the driven shafts 508 are respectively flush with the hydraulic motor bodies 503 at the corresponding heights. 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 at both sides are peripherally engaged and wound with a full-circle translation rotating chain 504. 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 translation rotating chain 504 at the upper position 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 translation rotating chain 504 at the lower position 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 base plate 403 at the lower layer 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, drive the table base plate 403 at the lower layer 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 layer 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 layer 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, 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 this setting is that safety monitoring can be carried out respectively before, during, and after 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 guide 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 reinforcement beam 305 for enhancing the overall strength of the guide beam 304. At the inner upper and lower positions 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 rotating 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 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 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 facilitate preventing 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 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 service ability.

[0045] 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 integral skeleton are welded to the bottom of the tabletop substrate 403 to facilitate the tabletop substrate 403 to have 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 position are designed with dislocation. Preferably, the reinforcing ribs 408 are intensively strengthened at the positions corresponding to the vehicle tires to facilitate the reliable and stable operation of the tabletop substrate 403 during the vehicle parking process. A heightening channel 404 is fixedly covered longitudinally 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 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 bracket 402. In this way, it is convenient to clearly indicate the parking in place by the way of the vehicle head or tail contacting the flexible safety net 401, ensuring that the driver can park the vehicle on the tabletop substrate 403 smoothly;

[0046] 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 limiting and guiding track 102 corresponds to the inner channel of the end frame column 101, so that the limiting and 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 use needs. Limiting and guiding plates 107 are vertically extended and fixed at the inner edge positions of the end frame columns 101 close to each other on both sides to limit and guide the vertical lifting process of the parking platform assembly 4 through the limiting and guiding plates 107. The upper and lower parts of the end frame columns 101 close to each other on both sides and the middle frame column 302 at the nearest outermost edge position are fixedly connected together by inserting and installing bolts. At the same time, extension connecting plates 106 are erected and extended and fixed at the middle positions of the end frame columns 101 close to each other on both sides 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 inserting and installing bolts through the extension connecting plates 106. In this way, 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. At the same time, the method of fixedly connecting through the extension connecting plate 106 can prevent the bolts from interfering with the smooth linear rolling of the limiting and guiding bearing 207 along the limiting and 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 in the middle position and the end frame cross beam 104 in 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 plate 105 and the lower guide chain plate 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 integral 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 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 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 setting length of the lifting chain 206 that meets the use 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 rotating chain 504 to rotate.

[0049] 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 intermediate frame cross beam 301 at the front position of the intermediate 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 intermediate frame component 3 are respectively installed in the middle and lower parts of the intermediate 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 run 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 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, 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 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, since there is a double-layer parking platform component 4, then in the case where the area of the parking lot is inconvenient, the double-layer parking platform component 4 can double the parking capacity. At the same time, it does not occupy new bottom space during setting, and only needs to perform secondary transformation on the original parking lot to complete the layout. Moreover, the parking platform component 4 has no strict height and weight restrictions on the parked vehicles, and the scope of use of the parked vehicles is wide and the applicability is good. Specifically, a double-layer circulating structure 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. The construction period is short, the comprehensive construction cost is low, the installation adaptability is strong, and the transformation space is large. 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 allow multiple cars to enter and exit at the same time, or can be set as a fixed single entrance according to the site needs. The setting method of the entrances and exits is flexible, which facilitates the entry and exit of vehicles, saves parking time and is conducive 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. Thus, by the way that the chain buckle 505 of the lower translation rotating chain 504 is stuck in the inner chain limit buckle 409 of the parking platform component 4, the parking platform component 4 at the lower layer can be driven to perform translational movement. At the same time, by the way that the chain buckle 505 of the upper translation rotating chain 504 is stuck in the outer chain limit buckle 407 of the parking platform component 4, the parking platform component 4 at the upper layer can be driven to perform translational movement. 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 side 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 chain carrier plates 308, ensuring that the chain buckle 505 of the lower translation drive chain 504 can cooperate and engage with the inner chain limit buckle 409 of the parking platform component 4 smoothly. 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 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 move in a cycle smoothly 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 movement 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 limit guiding bearings 207 are installed at the two ends of the upper lifting cross beam 201 and the lower lifting frame 202, the limit guiding during the lifting process 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 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, 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 successfully complete the cyclic 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, thereby ensuring the 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 the setting of the raised channel 404 facilitates getting on and off the vehicle more conveniently 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.
