Description

Technical Field

[0001] The present invention relates to a traffic device, in particular to a double-deck parking device. Background Art

[0002] With the development of the economy, the ownership of private cars in cities is also increasing continuously. In order to meet the parking needs of citizens as much as possible within the limited urban space, three-dimensional parking devices have emerged as the times require. The three-dimensional parking devices include double-deck parking devices and multi-layer parking devices. Among them, the double-deck parking device is the most widely used because of its relatively fast construction speed and relatively high safety.

[0003] The Chinese utility model patent with the publication number of CN206397233U discloses a double-deck parking device, which includes a walking chassis placed on a ground rail, a rotating support column arranged on the walking chassis, a lifting parking platform arranged on the rotating support column. The walking chassis is provided with a walking mechanism and a driving mechanism, and the walking chassis is also provided with a rotating mechanism and a stroke limiting mechanism connected to the rotating support column. The rotating support column is provided with a lifting mechanism with a parking platform and an anti-falling mechanism. The rotating support column of this double-deck parking device simply adopts a square hollow column, and most of the torsion applied by the square hollow column parking platform makes the rotating support column prone to fatigue after long-term use, and its service life is relatively short.

[0004] In view of this, the applicant of the present invention has conducted in-depth research on the above problems, and thus this case has arisen. Summary of the Invention

[0005] The purpose of the present invention is to provide a double-deck parking device with a relatively high service life.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A double-deck parking device includes a walking track horizontally installed on the ground, a walking box cooperating with the walking track, a guide post vertically arranged on the walking box, a lifting seat vertically slidably connected to the guide post, a car carrier plate fixedly connected to the lifting seat, and a lifting driving device for driving the lifting seat to slide relative to the guide post.

[0008] Support plates are respectively fixedly connected to the front and rear sides of the guide post. The cross-section of the support plate is trapezoidal. Buffer plates are arranged on the sides of each support plate away from the guide post. V-shaped grooves are formed on the sides of the buffer plates facing the corresponding support plates. The two side walls of the V-shaped grooves abut against the side walls of the corresponding support plates corresponding to the trapezoidal sides of their cross-sections, and the upper and lower ends of the buffer plates are respectively fixedly connected to the support plates.

[0009] As an improvement of the present invention, the front side of the buffer plate located on the front side of the guide column is fixedly connected or integrally connected with a hanging plate, and the hanging plate is provided with a plurality of locking grooves or locking holes arranged in sequence from top to bottom, and the upper end of the lifting seat is rotatably connected with a hook that cooperates with the locking groove or the locking hole, and the upper end of the hook is connected with a lifting member that is transmission-connected to the lifting drive device, and the lower end has a hook portion for penetrating into the locking groove or the locking hole, and the vertical plane where the rotating connection axis of the hook and the lifting seat is located is assumed to be a reference plane. When the hook is lifted upward by the lifting member, the connection position between the lifting member and the hook and the center of gravity of the hook are both located on the side of the reference plane away from the locking groove or the locking hole.

[0010] As an improvement of the present invention, the lifting seat is rotatably connected to a draw hook at a position directly below the hook, and the draw hook includes a rod portion which is gradually inclined from bottom to top toward the hanging plate, and a hook portion which is fixedly connected or integrally connected to the upper end of the rod portion for cooperating with the lock slot or the lock hole. The lifting seat is also provided with a safety motor for driving the draw hook to rotate and a weightlessness sensor cooperating with the safety motor.

[0011] As an improvement of the present invention, the weightlessness sensor includes a vertically arranged guide sleeve, a spring inserted in the guide sleeve, a counterweight ball abutting against the upper end of the spring, and an induction switch located above the counterweight ball, the upper end of the spring passes through the guide sleeve, and the diameter of the counterweight ball is larger than the inner diameter of the guide sleeve.

[0012] As an improvement of the present invention, the lower side wall of the lock groove or the lock hole is an inclined side wall which is gradually inclined upward from a side relatively close to the guide column to a side relatively far away from the guide column.

[0013] As an improvement of the present invention, the car-carrying board includes two side beams arranged in parallel with each other, and a horizontal plate group and a corrugated plate group respectively located between the two side beams. There are two groups of the corrugated plate groups, and the two groups of the corrugated plate groups are respectively located on both sides of the horizontal plate group. The water level position of the horizontal plate group is higher than the horizontal position of the corrugated plate group. Slope plates are respectively connected between each corrugated plate group and the horizontal plate group. The horizontal plate group includes a plurality of square steel pipes arranged in sequence along the length direction of the side beam. Two ends of each square steel pipe are respectively fixedly connected to the corresponding side beam. The corrugated plate group includes a plurality of profiles arranged in sequence along the length direction of the side beam. Two ends of each profile are respectively fixedly connected to the corresponding side beam. The profile includes two side plates arranged vertically respectively, and a panel located between the two side plates and integrally connected to the upper ends of the side plates. Triangular convex strips protruding upward and arranged along the length direction of the panel are formed on the panel. In the same profile, a first connecting plate located directly below the panel is integrally connected to the lower end of one of the side plates, and a second connecting plate located below the side of the panel is integrally connected to the lower end of the other side plate; the first connecting plates on the opposite sides of two adjacent profiles abut against the corresponding second connecting plates and are fixedly connected to each other by bolts.

[0014] As an improvement of the present invention, the traveling track includes a base plate for connecting with the ground, an I-shaped guide rail and a helical gear rack fixedly connected to the base plate and arranged in parallel with each other. There are two I-shaped guide rails and two helical gear racks respectively. The two helical gear racks are respectively located between the two I-shaped guide rails, and the inclination directions of the teeth on the two helical gears are opposite; the traveling box includes a box body. Traveling wheel groups that are in one-to-one cooperation with each I-shaped guide rail are respectively arranged on both sides of the box body, and helical gears that are respectively engaged with each helical gear rack are also arranged at the position of the box body between the two groups of traveling wheel groups. A traveling motor for driving each helical gear to rotate is also arranged in the box body.

[0015] As an improvement of the present invention, bellows protective covers or stainless steel telescopic covers are respectively arranged between the two ends of the box body and the traveling track.

[0016] As an improvement of the present invention, the lifting seat includes a horizontally arranged bottom plate, a front plate and a side plate which are vertically arranged and welded to the bottom plate respectively. Among them, there are two side plates, and the two side plates are arranged in parallel. The front plate is located between the two side plates. The front plate and the two side plates together form a U-shaped cavity. A connecting plate parallel to the side plate is fixedly connected to one side of the front plate facing the U-shaped cavity. A front guide wheel set is respectively arranged between each connecting plate and the side plate relatively close to the connecting plate. A rear guide wheel set is arranged between the two side plates. The front guide wheel set and the rear guide wheel set are arranged up and down in a staggered manner and are respectively located on the front and rear sides of the guide post.

[0017] As an improvement of the present invention, a side guide wheel assembly is further arranged on the lifting seat. The side guide wheel assembly includes a first nylon wheel arranged on one of the side plates and a nylon wheel set arranged on the other side plate and corresponding to the first nylon wheel. The nylon wheel set includes a swing plate rotatably connected to the corresponding side plate and second nylon wheels respectively arranged at both ends of the swing plate.

[0018] Adopting the above technical solutions, the present invention has the following beneficial effects:

[0019] 1. By arranging the support plate and the buffer plate, the anti-torsion performance of the guide post is effectively improved, and thus the service life of the guide post is extended.

[0020] 2. By arranging the hook, when the lifting member of the parking equipment fails, the hook can be inserted into the lock groove or the lock hole under the action of gravity to prevent the lifting seat and the parking platform from falling. Since the hook operates by gravity and does not require electronic components, the safety is relatively high.

[0021] 3. By arranging the hook and the weightlessness sensor, when the descending speed of the car carrier plate is too fast and a weightlessness situation exceeding the preset threshold occurs, the safety motor drives the hook to swing downward to hook the lock groove or the lock hole, jointly forming a double protection with the hook, avoiding the failure of the protection caused by the fact that the hook cannot operate under the action of gravity due to the pulling force of the lifting member, and the safety is relatively high.

[0022] 4. The weightlessness sensor adopted by the present invention uses a counterweight ball to achieve mechanical detection, with relatively high accuracy and relatively low failure rate.

[0023] 5. A spliced ​​structure is formed by setting a horizontal plate group and a corrugated plate group. When one of the square steel tubes or profiles is damaged or fails the inspection, only the corresponding square steel tube or profile needs to be replaced, and the maintenance cost is relatively low. At the same time, since the horizontal position of the horizontal plate group is higher than that of the corrugated plate group, when the driver drives the vehicle to the loading plate, the front wheels of the vehicle will have an uphill and downhill action, so that the driver can intuitively know that the vehicle is in the relatively middle position of the loading plate after completing the downhill action, without repeated adjustments, and the experience is relatively good.

[0024] 6. By forming a triangular boss profile wave structure on the profile panel, it helps to improve the stability of the vehicle after parking. By arranging the first connecting plate and the second connecting plate on the profile, the connection structure is more stable.

[0025] 7. By using helical gears and helical racks, the force between the two can be dispersed into two components in the length direction and width direction of the rack. The helical teeth are easy to mesh, and collisions are not likely to occur between the meshing teeth, which effectively avoids tooth damage and has a relatively long service life.

[0068] The following further describes the invention in conjunction with specific embodiments:

[0069] As Figures 1 - 11 shown, the parking equipment provided in this embodiment includes a traveling track 10 horizontally installed on the ground, a traveling box 20 cooperating with the traveling track 10, a guide post 30 installed on the traveling box 20 and vertically arranged, a lifting seat 40 vertically slidably connected to the guide post 30, a car carrier 50 fixedly connected to the lifting seat 40, and a lifting drive device 60 for driving the lifting seat 40 to slide relative to the guide post 30. When necessary, it may also include an upper track located directly above the traveling track 10, arranged parallel to the traveling track 10 and slidably connected to the guide post 30 to improve the stability of the guide post 30. Of course, the parking equipment provided in this embodiment also includes a control module for controlling the working sequence of the traveling box 20 and the lifting drive device 60. This control module is a conventional module, which can be directly purchased from the market and set according to actual functional requirements, and is not the focus of this embodiment, so it will not be elaborated here.

[0070] As Figure 2 and Figure 3As shown in the figure, the walking track 10 includes a base plate 11 for connecting to the ground, an I-shaped guide rail 12 and a helical rack 13 that are respectively fixedly connected to the base plate 11 and arranged in parallel with each other. Among them, there are two I-shaped guide rails 12 and two helical racks 13. The two helical racks 13 are respectively located between the two I-shaped guide rails 12, and the inclination directions of the teeth on the two helical gears 13 are opposite. Preferably, an arc groove is provided at the upper end of the I-shaped guide rail 12. First trapezoidal grooves 14 are respectively formed on the opposite sides of the two I-shaped guide rails 12, and second trapezoidal grooves 15 are respectively formed on the facing sides of the two I-shaped guide rails 12.

[0071] The walking box 20 includes a box body 21. Walking wheel sets 22 that are in one-to-one cooperation with the respective I-shaped guide rails 12 are respectively provided on both sides of the box body 21. Each walking wheel set 22 includes at least one walking wheel. The radial cross-sectional shape of the wheel rim of each walking wheel is the same as the cross-sectional shape of the corresponding arc groove, which helps to reduce the probability of the walking wheel derailing and improve the walking stability. It should be noted that the walking wheels are installed on the side of the side plate of the box body 21 facing its inner cavity to prevent the walking wheels from being exposed. Preferably, rubber sleeves are covered on the peripheries of the respective walking wheels.

[0072] The box body 21 is also provided with helical gears 23 that are respectively in cooperation with the respective helical racks 13 at the positions between the two groups of walking wheel sets 10. A walking motor (not shown in the figure) for driving the rotation of each helical gear is also provided in the box body 21. The specific connection structure between the walking motor and the helical gear 23 can be a conventional structure. In this embodiment, the walking motor is connected to the two helical gears 23 respectively through a double-output shaft reducer.

[0073] First side wheel sets 24 installed on the box body 21 are respectively provided in the respective first trapezoidal grooves 14. Each first side wheel set 24 includes at least one first side guide wheel that abuts against the upper side wall of the corresponding first trapezoidal groove 14. It should be noted that the peripheral surface of the first side guide wheel is a conical surface that cooperates with the side wall of the first trapezoidal groove 14. Preferably, a horizontally arranged pulley 25 is also provided at the position of the box body 21 between the two groups of walking wheel sets 22. The pulley 25 is inserted into each of the second trapezoidal grooves 15 at the same time, and there is a small gap between the pulley 25 and the bottom of each second trapezoidal groove 15, that is, the helical gear 23 and the pulley 25 are arranged along the length direction of the walking track 10. When the box body 21 is slightly flipped due to torsion, the pulley 25 will abut against the bottom of one of the second trapezoidal grooves 15 to form a support. Of course, two pulleys that respectively abut against the two second trapezoidal grooves 15 one by one can also be provided, and the above effects can also be achieved.

[0074] In addition, bellows protective covers or stainless steel telescopic covers (not shown in the figure) that can be directly purchased from the market are respectively arranged between the two ends of the box body 21 and the traveling track 10 to prevent sundries from falling between the two I-shaped guide rails 12 of the traveling track 10 and affecting the normal operation of the traveling mechanism. Of course, a rotating seat 26 that cooperates with the guide post 30 (see Figure 1 ) and a rotating motor (not shown in the figure) for driving the rotating seat 26 to rotate are also arranged on the box body 21. The specific structure of the rotating seat 26, the specific connection structure between the rotating seat 26 and the box body 21, and the specific connection structure between the rotating motor and the rotating seat 26 are the same as those of conventional three-dimensional parking equipment and will not be elaborated here.

[0075] As Figures 4 - 9 shown, for the convenience of description, in this embodiment, the side of the guide post 30 facing the parked vehicle (i.e., the side facing the car carrier 50) when in use is defined as the front side of the guide post 30 and the lifting seat 40, and the opposite side is defined as the rear side of the guide post 30 and the lifting seat 40. It should be noted that since the guide post 30 and the lifting seat 40 will rotate, the front side of the guide post 30 and the lifting seat 40 will change with their different rotation states.

[0076] The guide post 30 is a square hollow column. Support plates 31 are respectively fixedly connected to the front and rear sides of the guide post 30. The cross-section of the support plate 31 is trapezoidal, and the side corresponding to the bottom edge of the trapezoid is fixedly connected to the guide post 30 in a form of bolt connection, welding or integral connection. Buffer plates 32 are arranged on the side of each support plate 31 away from the guide post 30. V-shaped grooves are formed on the side of the buffer plate 32 facing the corresponding support plate 31. The two side walls of the V-shaped groove abut against the side walls of the corresponding support plate 31 corresponding to the trapezoidal sides of its cross-section, and the upper and lower ends of the buffer plate 32 are respectively fixedly connected to the support plate 31 by bolts, which helps to increase the torsional resistance of the guide post 30, improve safety and service life. In addition, a hanging plate 33 is fixedly connected or integrally connected to the front side of the buffer plate 32 located on the front side of the guide post. A plurality of lock grooves or lock holes are arranged on the hanging plate 33 in a straight line from top to bottom.

[0077] The lifting seat 40 includes a horizontally arranged bottom plate 43, a front plate 41 and side plates 42 which are vertically arranged and welded to the bottom plate 43 respectively. Among them, there are two side plates 42, and the two side plates 42 are arranged in parallel. The front plate 41 is located between the two side plates 42, and both sides of the front plate 41 are welded to the corresponding side plates 42 respectively. The front plate 41 and the two side plates 42 together form a U-shaped cavity. The bottom plate 43 is provided with a notch at a position corresponding to the U-shaped cavity, and the bottom plate 43 is provided with a first through hole for inserting the front plate 41 and each side plate 42, that is, the cross-sectional shape of the first through hole is the same as the cross-sectional shape of the whole formed after the connection of the front plate 41 and each side plate 42. The bottom plate 43, the front plate 41 and each side plate 42 are welded to the bottom plate 42 respectively at positions on both sides of the first through hole, that is, welding treatment is carried out on both sides of the bottom plate 43. This connection structure of first tenon-mortise connection and then welding is relatively firm and not easily damaged.

[0078] Preferably, rib plates 44 are respectively welded to the lower parts of the front plate 10 and each side plate 42. Second through holes that are in one-to-one correspondence with the respective rib plates 44 are formed in the bottom plate 13. Each rib plate 44 is inserted into the corresponding second through hole, and each rib plate 44 is welded to the bottom plate 13 at positions on both sides of the second through hole, which helps to further improve the stability of the lifting seat 40. In addition, a hook 45 that is engaged with the locking groove or the locking hole is rotatably connected to the upper end of the lifting seat 40. Specifically, two support plates 45a are fixedly connected to the front plate 41, and the hook 45 rotates on the two support plates 45a through a rotating shaft 45b (that is, the two ends of the rotating shaft 45b are rotatably connected to the two support plates 45a in one-to-one correspondence); a lifting member 81 that is drivingly connected to the lifting driving device 80 is connected to the upper end of the hook 45, and a hook portion for penetrating into the locking groove or the locking hole is provided at the lower end. Taking the vertical plane where the rotating connection shaft (i.e., the rotating shaft 45b) of the hook 45 and the lifting seat 40 is located as the reference plane, when the hook 45 is lifted upward by the lifting member 81, the connection position between the lifting member 81 and the hook 45 and the center of gravity of the hook 45 are both located on the side of the reference plane away from the locking groove or the locking hole 34, so as to ensure that when the lifting member 81 fails to lift the hook 45 upward due to a break or other faults, the hook 45 can rotate along the rotating shaft 45b under the action of gravity, so that the hook portion penetrates into a certain locking groove or locking hole, to prevent the lifting seat 40 from sliding towards each other. It should be noted that during use, regardless of whether the lifting seat 40 is in the ascending, descending or stationary state, the lifting member 81 will lift the hook 45 upward, but the force with which the lifting member 81 lifts upward is different in different states. That is to say, when the lifting seat 40 descends, it is not in free fall and is still pulled by the lifting member 81. The lifting member 81 can be a conventional part, such as a lifting rod, a lifting rope or a chain, etc., as long as it can lift the hook 45 upward to drive the lifting seat 40 to slide relative to the guide post 30, which will not be elaborated here. In this embodiment, the lifting member 81 is a chain, and the lifting driving device 60 is a motor driving device. The motor driving device has a motor and a sprocket that cooperates with the chain to drive the chain to act in sequence. The specific connection structure between the lifting driving device 60 and the lifting member 81 is the same as that of a conventional double-deck parking device and is not the focus of this embodiment, so it will not be elaborated here.

[0079] Further, the lifting seat 40 is rotatably connected with a hook 82 at a position directly below the hook 45. The hook 82 includes a rod portion that is gradually tilted from bottom to top toward the hanging plate 33 and a hook portion that is fixedly connected or integrally connected to the upper end of the rod portion for cooperating with the lock slot or lock hole 34. At the same time, the lifting seat 40 is also provided with a safety motor 83 for driving the hook 82 to rotate and a weightlessness sensor 70 that cooperates with the safety motor 83. The weightlessness sensor 70 and the safety motor 83 can be coordinated through a control module. In order to improve the safety performance, in this embodiment, the weightlessness sensor 70 and the safety motor 83 are 3 is connected through an independent PLC control chip communication. When the vehicle loading plate 50 falls or descends too fast and a preset threshold value of weightlessness occurs, the weightlessness sensor 70 sends a signal to the PLC control chip, and the PLC control chip controls the safety motor 83 to drive the hook 82 to swing toward the hanging plate 33, so that it hooks the lock slot or lock hole 34 to form a hook lock state to prevent the vehicle loading plate 20 from continuing to fall; when the hook lock state needs to be released, the vehicle loading plate 20 can be driven to move upward a short distance through the lifting drive device 60, and then the safety motor 83 is used to make the hook 82 disengage from the corresponding lock slot or lock hole 34. It should be noted that the lower side wall of the lock slot or lock hole 34 is preferably an inclined side wall that is gradually inclined upward from the side relatively close to the guide column 30 to the side relatively far from the guide column 30, so as to facilitate the hook 82 to hook, and also help to prevent the hook 82 from slipping after hooking.

[0080] The weight loss sensor 70 can be directly purchased on the market. In order to improve the accuracy of the weight loss sensor 70 and reduce its failure rate, preferably, the weight loss sensor 70 provided in this embodiment includes a vertically arranged guide sleeve 71, a spring 72 inserted into the guide sleeve 71, a counterweight ball 73 abutted against the upper end of the spring 72, and an induction switch 74 located above the counterweight ball 73. Among them, the lower end of the spring 72 is fixedly connected to the guide sleeve 71, and the upper end of the spring 72 will pass through the guide sleeve 71 regardless of whether it is impacted by the pressure of the counterweight ball 73, so as to prevent the counterweight ball from directly hitting the guide sleeve 71. Of course, the diameter of the counterweight ball 73 is larger than the inner diameter of the guide sleeve 71, so the counterweight ball 73 cannot penetrate into the guide sleeve 71. In addition, a cylinder 75 with a diameter slightly larger than that of the counterweight ball 73 is fixedly connected to the upper end of the guide sleeve 71. The counterweight ball 73 and the induction switch 77 are both located inside the cylinder 75 to ensure that the counterweight ball 73 can only move up and down inside the cylinder 75. When in use, during the process of the weight loss sensor 70 descending with the carrier plate 20, if a weightless state occurs, the counterweight ball 73 will move upward relative to the guide sleeve 71 with the assistance of the spring 72. When the counterweight ball 73 touches the induction switch 74, the weight loss sensor 70 is triggered and sends a signal to the control module. It should be noted that the height position of the induction switch 74 inside the cylinder 75 can be adjusted, that is, the induction switch 74 is connected to the cylinder 75 through an adjustable structure. The specific adjustable structure is a conventional structure, such as a sliding connection or a detachable connection, etc. In this way, the distance between the induction switch 74 and the counterweight ball 73 can be adjusted by adjusting the height position of the induction switch 74, and then the preset threshold of the weight loss sensor 70 can be adjusted.

[0081] Two connecting plates arranged parallel to the side plates 42 are fixedly connected to the side of the front plate 41 of the lifting seat 40 facing the U-shaped cavity. A front guide wheel group 46 is respectively arranged between each connecting plate and the side plate relatively close to the connecting plate, that is, there are two groups of front guide wheel groups 46, and the two groups of guide wheel groups 46 are arranged horizontally. Since the weight at the front of the vehicle is usually greater than that at the rear of the vehicle, when in use, the carrier plate or the parking platform will not only apply a downward pulling force to the lifting platform 40, but also apply a torsional force to it. Therefore, the forces received by the two groups of front guide wheel groups 46 are different. Compared with directly arranging the front guide wheel group 46 between the two side plates 42, its rotating shaft is less likely to break, and a part of the torsional force can be offset through the cooperation of the support plate 31 and the buffer plate 32.

[0082] A rear guide wheel set 47 is arranged between two side plates 42. The front guide wheel set 46 and the rear guide wheel set 47 are arranged in an up-and-down staggered manner and are respectively located on both sides of the guide post 30, and respectively abut against the corresponding buffer plates 32 to prevent the lifting seat 40 from shaking back and forth. In addition, a side guide wheel assembly is also arranged on the lifting seat 40. The side guide wheel assembly includes a first nylon wheel 48 arranged on one of the side plates 42 and a nylon wheel set 49 arranged on the other side plate 42 and corresponding to the first nylon wheel 48. The nylon wheel set 49 includes a swing plate 49a rotatably connected to the corresponding side plate 42 and second nylon wheels 49b respectively arranged at both ends of the swing plate 49a. Of course, the rotation connection shaft of the swing plate 49a and the corresponding side plate 42 is located between the two second nylon wheels 49b, so as to form a seesaw structure to ensure that the first nylon wheel 48 and one of the second nylon wheels 49b are tightly attached to the guide post 30 to prevent the lifting seat 40 from shaking left and right. Preferably, in this embodiment, there are more than two side guide wheel assemblies, and the side guide wheel assemblies are arranged in sequence from top to bottom, and the first nylon wheels 48 of adjacent two side guide wheel assemblies are located on different side plates 42.

[0083] Preferably, in this embodiment, a fall prevention assembly is arranged at the upper end of the guide post 30. The fall prevention assembly includes an induction switch cooperating with the lifting seat 40, an execution motor communicatively connected to the induction switch through a wire, and a lifting hook (the specific transmission connection structure can be a conventional structure, such as direct fixed connection between the two, etc.) drivingly connected to the execution motor. A hook portion cooperating with the lifting hook is arranged on the lifting seat 40. When the lifting seat 40 rises to the upper limit position, it will touch the induction switch. After the induction switch is touched, the execution motor drives the lifting hook to hook the hook portion to prevent the lifting seat 40 from falling. Of course, the execution motor should also be communicatively connected to the control module so as to control the execution motor to release the lifting hook from the hook portion when the lifting seat 40 needs to descend.

[0084] As Figure 10 and Figure 11 shown, the vehicle-carrying plate 50 is used to carry a vehicle, and it can adopt a conventional vehicle-carrying plate. In this embodiment, the vehicle-carrying plate 50 includes two side beams 510 arranged in parallel with each other and a horizontal plate group 520 and a corrugated plate group 530 respectively located between the two side beams 510. Among them, there are two groups of corrugated plate groups 530, and the two groups of corrugated plate groups 530 are respectively located on both sides of the horizontal plate group 520. When the vehicle is parked on the vehicle-carrying plate 50, its front wheels and rear wheels are respectively located on different corrugated plate groups 530.

[0085] The water level of the horizontal plate group 520 is higher than the horizontal position of the wave plate group 530. A ramp plate 540 is connected between each wave plate group 530 and the horizontal plate group 520, that is, there are two ramp plates 540, and the inclination directions of the two ramp plates 540 relative to the horizontal plane are different. When in use, when the driver drives the vehicle to the vehicle loading plate 50, the front wheel of the vehicle will have an uphill and downhill action, so that the driver can intuitively see that the vehicle is already in the relatively middle position of the vehicle loading plate 50 after completing the downhill action, without repeatedly adjusting the vehicle position, and the experience is relatively good. Preferably, in order to facilitate the vehicle to drive onto the vehicle loading plate 50, a side of each wave plate group 530 away from the horizontal plate group 520 is respectively provided with an inclined guide plate 550 fixedly connected to the side plate 510, that is, there are two inclined guide plates 550, and the inclination directions of the two inclined guide plates 550 relative to the horizontal plane are different. In addition, the inclination angle of the ramp plate 540 and / or the inclined guide plate 550 relative to the horizontal plane is preferably 20°-45°.

[0086] The horizontal plate group 520 includes a plurality of square steel tubes (not shown) arranged in sequence along the length direction of the side beam 510. Each square steel tube is arranged perpendicular to the side beam 510 and its two ends are respectively connected to the corresponding side beam 510 by welding or bolts. Two adjacent square steel tubes are locked by bolts. Of course, the square steel tubes can also be replaced by steel bars with a U-shaped cross section. In addition, if necessary, decorative panels can be laid on top of each square steel tube.

[0087] The corrugated plate group 530 includes a plurality of profiles 531 arranged in sequence along the length direction of the side beam 510. Each profile 531 is perpendicularly arranged to the side beam 510, and its two ends are respectively fixedly connected to the corresponding side beam 510 by welding or bolts. The thickness of the profile 531 is preferably above 3 mm, and the profile 531 is preferably an alloyed galvanized steel (i.e., a galvanized steel with a relatively low aluminum content in the galvanized layer), having good rust prevention ability. The profile 531 includes two side plates 532 arranged vertically respectively and a panel 533 located between the two side plates 532 and integrally connected to the upper ends of the respective side plates 532. Among them, at least one triangular rib 534 that protrudes upward and is arranged along the length direction of the panel 533 is formed on the panel 533. In this embodiment, there are two triangular ribs 534 on each panel 533, and the distance between the two triangular ribs 534 is 100 - 200 mm, preferably 140 mm. In the same profile, a first connecting plate 535 located directly below the panel 533 is integrally connected to the lower end of one of the side plates 532, and a second connecting plate 536 located below the side of the panel 533 is integrally connected to the lower end of the other side plate 532, that is, both connecting plates are on the same side of the corresponding side plate 532. The lower side of the first connecting plate 535 on the opposite side of adjacent two profiles 531 abuts against the upper side of the corresponding second connecting plate 536, and the two are fixedly connected to each other by bolts. In this way, when in use, the main force borne by the bolt is the radial shear force (of course, it also needs to bear the axial force, but its force value is relatively low), and it is more difficult to be damaged and more difficult to loosen. It should be noted that in order to ensure that the upper end faces of adjacent two profiles 531 are flush, the sum of the height of the side plate connected with the first connecting plate 535 and the thickness of the corresponding first connecting plate 535 is equal to the height of the side plate connected with the second connecting plate 536 (allowing for errors). Preferably, the width of the second connecting plate 536 is greater than the width of the first connecting plate 535, and a vertically arranged baffle 537 is integrally connected to the side of the second connecting plate 536 away from the corresponding side plate 532, so as to realize the rapid lapping of adjacent two profiles 531, which helps to improve the production efficiency.

[0088] Preferably, in this embodiment, a lower radar sensing device (not shown in the figure) is provided on the lower side of the horizontal plate group 520 and / or each corrugated plate group 530. In this way, when the carrier board 50 descends, it can confirm whether there are people or objects below through the lower radar sensing device, improving the safety and reliability of the parking equipment. An upper radar sensing device (not shown in the figure) is provided at the middle position on the upper side of the horizontal plate group 520, which is used to confirm whether there is a vehicle on the carrier board 50, so as to form a closed-loop feedback in the control system of the double-deck parking equipment. The radar sensing device can be directly purchased from the market and will not be elaborated here.

[0089] Preferably, pressure sensing devices (not shown in the figure) are respectively provided on each ramp plate 540, and a signal lamp assembly 511 cooperating with the pressure sensing devices is provided on one of the side beams 510. Both the pressure sensing devices and the signal lamp assembly 511 are components that can be directly purchased from the market. During use, when the car-carrying plate is in an ungrounded state, the signal lamp assembly 511 always gives a signal prohibiting driving (i.e., the red light is on). After the car-carrying plate is stably placed on the ground, the signal lamp assembly 511 gives a signal allowing driving (i.e., the green light is on). After the two pressure sensing devices are pressed in sequence once, it means that a vehicle has driven out or in, and the signal lamp assembly 511 always gives a signal prohibiting driving to prepare for the reset of the car-carrying plate 50. If only one pressure sensing device is pressed or one of the pressure sensing devices is pressed twice, it indicates that the vehicle is not properly placed or there are potential safety hazards, and the signal lamp assembly 511 gives a warning signal (i.e., the yellow light is on).

[0090] The double-deck parking equipment provided in this embodiment has two parking spaces. One is a ground parking space beside the traveling track 10, and the other is an upper-layer parking space provided on the car-carrying plate 50. When in use, the ground parking space can be parked in the conventional manner, which will not be elaborated here. When the vehicle needs to be parked in the upper-layer parking space, first, the rotary motor drives the guide column 30 to drive the car-carrying plate 50 to move from the position directly above the ground parking space to the position directly above the road in front of the ground parking space (i.e., the side above the ground parking space). At the same time, the traveling motor drives the traveling box 20 to drive the guide column 30 to move in the direction of the road in front of the ground parking space. Then, the lifting drive device 60 drives the lifting seat 40 to descend so that the car-carrying plate 50 is placed on the ground. After that, the vehicle is driven onto the car-carrying plate 50, and then each drive device 60 is used to control the reset of the car-carrying plate 50 so that it returns to the position directly above the ground parking space, completing the parking process.

[0091] The above has made a detailed description of the present invention in conjunction with the drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various deformations to the present invention according to the prior art, and these all belong to the protection scope of the present invention.
