Description

Technical Field

[0001] The invention relates to the technical field of parking equipment, in particular to a steel structure frame three-dimensional parking garage used in a basement. Background Art

[0002] Due to limited space in basement garages, double-layer lifting and sliding stereoscopic parking garages are often installed. The lower parking platform of the lifting and sliding stereoscopic parking garage can move horizontally, while the upper parking platform can be lifted and lowered. The upper parking platform mainly relies on motors to realize the lifting and lowering of vehicles. The motor drives the chain to pull the upper parking platform up and down. When a vehicle needs to be parked on the upper level, the lower parking platform directly below the vehicle is first translated to reserve space for the upper parking platform, and then the upper parking platform is lowered. After the vehicle enters the upper parking platform, the control system issues a command, the motor starts, and drives the chain to raise the upper parking platform to the specified position.

[0003] The existing basement multi-story parking garage requires the lower parking platform to move horizontally when parking and retrieving vehicles on the upper level. Therefore, during the peak period of vehicle parking and retrieving, the parking and retrieving of vehicles on the upper level will affect the parking and retrieving operations of vehicles on the lower level, so the efficiency is low. In addition, after the upper-level vehicle is parked, the gravity of the upper-level vehicle is mainly borne by the chain. Since the chain itself is flexible, the upper-level vehicle is prone to shaking during the parking process, increasing the risk of the vehicle rolling over and falling. Therefore, it does not meet the existing needs. In this regard, we propose a steel structure frame multi-story parking garage for the basement. Summary of the invention

[0004] The present invention provides a steel structure frame multi-story parking garage for a basement, which has a fixed lower parking platform and an upper parking platform. Parking and taking out vehicles on the upper level will not affect parking and taking out vehicles on the lower level. The parking and taking out efficiency of vehicles is relatively high, and the upper level vehicles are not prone to shaking after being parked and taken out, thereby reducing the risk of vehicle rollover and falling. The present invention solves the problem mentioned in the above background technology that the existing basement multi-story parking garage requires the lower level parking platform to perform translational coordination when parking and taking out vehicles on the upper level. Therefore, during the peak period of vehicle parking and taking out, the parking and taking out of the upper level vehicles will affect the parking and taking out operations of the lower level vehicles, so the efficiency is relatively low. In addition, after the upper level vehicle is parked, the gravity of the upper level vehicle is mainly borne by the chain. Since the chain itself is flexible, the upper level vehicle is prone to shaking during the parking process, increasing the risk of vehicle rollover and falling.

[0022] The present invention has the following beneficial effects:

[0023] 1. The steel structure frame three-dimensional parking garage used in the basement has a lower parking platform and an upper parking platform fixed on a garage bracket. When the upper vehicle is parked, since the upper parking platform is fixed, the mobile base is placed on the upper parking platform for greater stability, reducing the risk of the upper vehicle tipping over and falling, thereby improving the safety of the device. Moreover, when the upper vehicle is parked or retrieved, it is only necessary to raise or lower the mobile base through an electric lifting platform. During this process, the parking or retrieval of the lower vehicle is not affected by the upper vehicle. During the peak period of vehicle parking or retrieval, the upper and lower vehicles can be parked or retrieved at the same time, thereby improving the efficiency of the device in parking or retrieval of vehicles.

[0024] 2. In the steel structure frame three-dimensional parking garage used in the basement, when the upper vehicle is parked or taken out, one end of the moving rod is located in the limiting groove on the guide plate. In the process of the moving rod moving from the No. 1 inclined slide groove to the straight slide groove, the moving rod moves toward the inside of the moving base, and the No. 1 protrusion installed at one end of the moving rod is in sliding contact with the No. 2 protrusion, thereby driving the rotating shaft to rotate, and further driving the No. 1 connecting rod and the No. 2 connecting rod to rotate. When rotating, the No. 2 connecting rod pushes the slide plate out of the No. 1 slide groove, and at the same time, the slide plate rack arranged at the bottom of the slide plate meshes with the guide gear on the upper parking platform. The guide gear assists in guiding the moving base by meshing with the slide plate, preventing the moving base from deviating during the movement, thereby ensuring that the base rack at the bottom of the moving base can always mesh with the passive gear, thereby improving the reliability of the device.

[0025] 3. In the steel structure frame three-dimensional parking garage used in the basement, after the vehicle is parked, the electric lift moves downward, and the first rack installed on the side of the electric lift engages with the one-way gear, driving the rotating rod to rotate, and further driving the two-way gear to rotate. Since the two-way gear engages with the second rack, the second rack moves upward, and the card plate installed on the top of the second rack moves up. When the card plate engages with the card slot set at the bottom of the mobile base, the insertion rod is inserted into the through hole under the action of the No. 3 tension spring to prevent the card plate from falling, thereby realizing the limitation of the mobile base, preventing the mobile base from moving due to the vibration of the garage bracket, making the mobile base more stable when the upper vehicle is parked, and further increasing the reliability of the device.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1: This embodiment aims to solve the problem that the existing basement multi-story parking garage requires the lower parking platform to move horizontally when parking and taking out the upper-level vehicle. Therefore, during the peak period of vehicle parking and taking out, the parking and taking out of the upper-level vehicle will affect the parking and taking out of the lower-level vehicle, so the efficiency is low. In addition, after the upper-level vehicle is parked, the gravity of the upper-level vehicle is mainly borne by the chain. Since the chain itself is flexible, the upper-level vehicle is prone to shaking during the parking process, increasing the risk of the vehicle rolling over and falling. Please refer to Figures 1 to 10A steel structure frame three-dimensional parking garage for a basement includes a garage support 101, on which an electric lifting platform 102 for lifting vehicles is arranged, a pair of lower parking platforms 201 and a pair of upper parking platforms 203 located on both sides of the electric lifting platform 102 are arranged on the garage support 101, the upper parking platform 203 is located directly above the lower parking platform 201, and a plurality of passive gears 208 are rotatably installed on the electric lifting platform 102 and the upper parking platform 203, a movable base 207 for parking vehicles is movably arranged on the upper parking platform 203, and a base rack 209 for meshing with the passive gear 208 is arranged at the bottom of the movable base 207.

[0039] Also, please refer to Figure 3 The mobile base 207 and the upper parking platform 203 are both provided with a driving mechanism 2100 for driving the mobile base 207 to move horizontally. The driving mechanism 2100 includes a driving gear 211, which is rotatably installed on the electric lifting platform 102 and the upper parking platform 203 respectively. The driving gear 211 is meshed with the base rack 209. The electric lifting platform 102 and the upper parking platform 203 are respectively provided with a motor 210 for driving the driving gear 211 to rotate.

[0040] Specifically, a transmission rod 212 is fixedly mounted on the side of the driving gear 211 , a driven bevel gear 213 is mounted on the transmission rod 212 , a driving bevel gear 214 is mounted on the output shaft of the motor 210 , and the driving bevel gear 214 meshes with the driven bevel gear 213 .

[0041] Also, please refer to Figure 4 The mobile base 207 is provided with a plurality of convex strips 204 for preventing the vehicle from slipping, and the mobile base 207 is provided with a limiting plate 205 and a limiting rod 206 for limiting the vehicle. A pair of limiting plates 205 are provided, and a pair of limiting plates 205 are respectively installed on both sides of the mobile base 207. The limiting rod 206 is arranged at one end of the mobile base 207, and vertical plates 202 for limiting the mobile base 207 are respectively installed on both sides of the garage bracket 101.

[0042] In this embodiment: the lower parking platform 201 and the upper parking platform 203 are fixedly arranged on the garage support 101. When the upper vehicle is parked, since the upper parking platform 203 is fixed, the mobile base 207 is placed on the upper parking platform 203 for greater stability, reducing the risk of the upper vehicle tipping over and falling, thereby improving the safety of the device. Moreover, when the upper vehicle is parked, it is only necessary to lift the mobile base 207 through the electric lifting platform 102. During this process, the parking and taking of the lower vehicle is not affected by the upper vehicle. During the peak period of vehicle parking and taking, the upper and lower vehicles can be parked and taken at the same time, thereby improving the efficiency of parking and taking vehicles by the device.

[0043] Embodiment 2: This embodiment is intended to promote the solution of the problem that the mobile base 207 is actively guided in the direction when the mobile base 207 moves, and prevents the mobile base 207 from tilting during the movement. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 10 A No. 1 slide groove 312 is provided at the bottom of the movable base 207, and a pair of slide plates 302 are slidably installed in the No. 1 slide groove 312. The pair of slide plates 302 are respectively located at the two ends of the No. 1 slide groove 312. A slide rack 309 is provided at the bottom of the slide plate 302. The electric lifting platform 102 and the upper parking platform 203 are both rotatably installed with a guide gear 303 for meshing with the slide rack 309. A movable rod 305 is slidably installed on the movable base 207, and the movable rod 305 is transmission-connected to the slide plate 302.

[0044] For details, please refer to Figure 5 , Figure 6 A No. 1 connecting rod 322 is hinged on the skateboard 302, and a No. 2 connecting rod 321 is hinged on one end of the No. 1 connecting rod 322. A rotating shaft 320 is rotatably installed on the movable base 207, and the rotating shaft 320 is fixedly connected to the No. 2 connecting rod 321. A No. 1 protrusion 318 is also fixedly installed on the rotating shaft 320. A No. 2 protrusion 317 is installed at one end of the movable rod 305. Both the No. 2 protrusion 317 and the No. 1 protrusion 318 are configured as arc protrusions, and the arc surface of the No. 2 protrusion 317 is in sliding contact with the arc surface of the No. 1 protrusion 318.

[0045] Also, please refer to Figure 5 Guide plates 301 are installed on both sides of the upper parking platform 203 respectively. A limiting groove 324 is opened on the side of the guide plate 301 close to the driving gear 211. The limiting groove 324 includes a No. 1 inclined groove 3041, a straight groove 3042 and a No. 2 inclined groove 3043. The No. 1 inclined groove 3041, the straight groove 3042 and the No. 2 inclined groove 3043 are connected in sequence. When the upper parking platform 203 parks or takes a vehicle, one end of the moving rod 305 slides with the inner wall of the limiting groove 324.

[0046] In addition, see Figure 5 A fixed plate 310 is installed at one end of the skateboard 302, a No. 1 tension spring 311 is installed on the side close to the skateboard 302, the other end of the No. 1 tension spring 311 is fixedly connected to the skateboard 302, and a No. 2 tension spring 314 is sleeved on the moving rod 305, and the other end of the No. 2 tension spring 314 is fixedly connected to the moving base 207.

[0047] In this embodiment: when the upper vehicle stops, the motor 210 drives the driving gear 211 to rotate, and the upper vehicle moves to the upper parking platform 203 along with the moving base 207. When the moving base 207 moves, one end of the moving rod 305 is located in the limiting groove 324 on the guide plate 301. When the moving rod 305 moves from the No. 1 inclined slide groove 3041 to the straight slide groove 3042, the moving rod 305 moves toward the inside of the moving base 207, and the No. 2 protrusion 317 installed at one end of the moving rod 305 slides in contact with the No. 1 protrusion 318, thereby driving the rotating shaft 320 to rotate, and further driving the No. 2 connecting rod 321 and the No. 1 connecting rod 322 to rotate. Since the other end of the No. 1 connecting rod 322 is hinged to the slide plate 302, the No. 1 connecting rod 322 will push the slide plate 302 out of the No. 1 slide groove 312 when it rotates, and at the same time, The skateboard rack 309 at the bottom of the skateboard 302 is meshed with the guide gear 303 on the upper parking platform 203. The guide gear 303 assists in guiding the mobile base 207 by meshing with the skateboard 302. When the mobile base 207 is translated, the garage bracket 101 will produce a certain degree of vibration, so that when the mobile base 207 moves to the upper parking platform 203, the base rack 209 at the bottom of the mobile base 207 is not well meshed with the passive gear 208 on the upper parking platform 203. The auxiliary guiding design of the guide gear 303 can prevent the mobile base 207 from deviating during the movement, and ensure that the base rack 209 at the bottom of the mobile base 207 can always mesh with the passive gear 208, so that the mobile base 207 is more stable during the movement process, thereby improving the reliability of the device.

[0048] Embodiment 3: This embodiment aims to solve the problem of limiting the position of the mobile base 207 after the upper vehicle is parked to prevent the mobile base 207 from moving. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figures 1 to 10 A limiting mechanism 4100 for limiting the movable base 207 is provided on the upper parking platform 203. The limiting mechanism 4100 includes a No. 2 slide groove 404. The No. 2 slide groove 404 is installed on the upper parking platform 203. A slider 406 is slidably installed in the No. 2 slide groove 404. A first rack 412 is installed on the side of the slider 406. A card plate 401 is installed on the upper end of the first rack 412. A card slot 416 for engaging with the card plate 401 is opened at the bottom of the movable base 207.

[0049] Also, please refer to Figure 7 , Fig. 9A support plate 409 is installed on the upper parking platform 203, and a plug rod 408 is slidably installed on the support plate 409. A No. 3 tension spring 413 is sleeved on the plug rod 408, and the other end of the No. 3 tension spring 413 is connected to the support plate 409. One end of the plug rod 408 is in contact with the card plate 401, and a pull plate 407 is installed on the other end of the plug rod 408. A through groove 415 is provided on the pull plate 407. A wedge block 403 is installed on the side of the electric lifting platform 102, and the wedge block 403 is located directly below the through groove 415. A through hole 417 is provided on the support plate 409, and the through hole 417 is located directly below the plug rod 408. When the card plate 401 moves upward, the plug rod 408 slides and engages with the through hole 417, and a No. 3 tension spring 413 is connected between the card plate 401 and the upper parking platform 203.

[0050] Also, please refer to Fig. 9 , Fig.10 A rotating rod 420 is rotatably installed on the upper parking platform 203, and a one-way gear 411 and a two-way gear 405 are installed on the rotating rod 420. The two-way gear 405 is meshed with a first rack 412. A second rack 402 is installed on the side of the electric lifting platform 102, and the second rack 402 is meshed with the one-way gear 411. A ratchet 418 is arranged in the one-way gear 411, and a pawl 419 is hinged on the rotating rod 420. The ratchet 418 is movably engaged with the pawl 419, wherein the pawl 419 can rotate unidirectionally through a spring. The ratchet and pawl are common mechanical matching means that are well known to those skilled in the art and will not be elaborated here.

[0051] It should be noted that when the electric lifting platform 102 moves downward, the second rack 402 installed on the side of the electric lifting platform 102 meshes with the one-way gear 411, and at this time the ratchet 418 and the pawl 419 engage, so that the one-way gear 411 drives the rotating rod 420 to rotate, and further drives the two-way gear 405 to rotate. Since the two-way gear 405 meshes with the first rack 412, the first rack 412 moves upward, and the card plate 401 installed on the top of the first rack 412 moves upward. When the card plate 401 is engaged with the card slot 416 set at the bottom of the moving base 207, the insertion rod 408 is inserted into the through hole 417 under the action of the No. 3 tension spring 413, preventing the card plate 40 When the vehicle is dropped down and the electric lifting platform 102 is picked up, the electric lifting platform 102 moves upward, the wedge block 403 installed on the side of the electric lifting platform 102 is slidably plugged with the pull plate 407, the pull plate 407 and the insertion rod 408 move away from the clamping plate 401, and the insertion rod 408 and the through hole 417 are no longer engaged, so that the clamping plate 401 moves downward under the tension of the No. 3 tension spring 413, so that the clamping plate 401 releases the limiting function of the movable base 207. In addition, during the rising process of the electric lifting platform 102, although the second rack 402 is engaged with the one-way gear 411, the ratchet 418 and the pawl 419 are not engaged, so the rotation of the one-way gear 411 will not cause the rotating rod 420 to rotate.

[0052] In this embodiment: after the vehicle is parked, the electric lifting platform 102 moves downward, and the second rack 402 installed on the side of the electric lifting platform 102 meshes with the one-way gear 411, driving the rotating rod 420 to rotate, and further driving the two-way gear 405 to rotate. Since the two-way gear 405 meshes with the first rack 412, the first rack 412 moves upward, and the card plate 401 installed on the top of the first rack 412 moves upward. When the card plate 401 is engaged with the card slot 416 set at the bottom of the mobile base 207, the insertion rod 408 is inserted into the through hole 417 under the action of the No. 3 tension spring 413 to prevent The card plate 401 falls, and the card plate 401 limits the mobile base 207, preventing the mobile base 207 from moving due to the vibration of the garage bracket 101, making the mobile base 207 more stable when the upper vehicle is parked, preventing the vehicle from collapsing and overturning during parking, and when taking the vehicle, the insertion rod 408 and the through hole 417 are no longer engaged, causing the card plate 401 to move downward under the tension of the No. 3 tension spring 413, so that the card plate 401 automatically releases the limiting function of the mobile base 207, thereby facilitating the removal of the mobile base 207, further increasing the reliability of the device.
