Description

Technical Field

[0001] The invention relates to the technical field of three-dimensional parking garages, in particular to a lifting and lateral shifting parking device based on core weight. Background Art

[0002] With the continuous compression of urban space and the continuous increase in the number of vehicles, parking issues have gradually become a difficult and key point in urban management, and a factor that cannot be ignored in affecting people's lives and production activities. Based on the limitations of space, the use of stereo garages has become the primary measure to solve the parking space problem. Stereo garages are divided into a variety of structures and modes. The first common use in underground garages (such as underground garages in public buildings or residential buildings) is the double-layer or three-layer lifting and sliding garage, which is based on the advantages of lightweight single-body structure, easy installation and layout, simple and safe transmission, etc., and is widely used in most indoor garages.

[0003] For stereo garages where parking spaces are subject to mechanical transmission, safety is the primary consideration. Since the use of stereo garages, a large number of safety accidents or property losses have occurred. For lifting and transverse shifting garages, the main safety issue comes from the lifting safety of the upper parking spaces. The falling of the upper parking spaces due to overloading, aging of wire ropes, transmission or control failure, etc., accounts for a large proportion of accidents in this type of garage. The root cause comes from the load and operation problems of the lifting pallet. In the existing management measures of underground garages, overload restrictions are mostly determined manually at the entrance and exit gates. Large and heavy vehicles will be required to park in designated areas or be prevented from entering. However, due to the unfavorable supervision after entering the warehouse, and with the development of electronic information, most gates have been changed to automatic identification, resulting in a lack of necessary control after heavy vehicles enter. After parking on the lifting parking pallet, the lifting equipment of the parking space (including wire ropes, motors, gearboxes, and other transmission and power facilities) will be overloaded, resulting in rapid wear or damage, which will bring safety hazards to subsequent vehicles. Summary of the invention

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0044] like Figure 1-11 As shown (in order to facilitate the clear display of the components and prevent the obstruction between the components, the coordination is clearly shown, the repeated structure is hidden in the figure, and only a single lower parking space and a single upper parking space are shown. It should be known that it is not limited to what is shown in the figure, and the upper and lower layers should be designed for multiple and unlimited number of parking spaces.) The device mainly includes a steel structure frame body, the frame body includes columns 1 located on both sides and between each parking space, and a shelf is welded and installed in the middle layer or / and the upper layer of the column 1. The shelf includes a longitudinal beam and a side beam. The longitudinal beam is a support beam whose length direction is consistent with the length direction of the garage. The longitudinal beam is fixedly installed on the front and rear sides of the frame body, and the side beam is a support beam consistent with the parking direction of the parking space. They are all welded with I-beams, and the side beams are arranged on both sides of the parking space. The shelf is divided into three groups of frame units 2 as shown in the figure by the longitudinal beams and side beams.

[0045] This example is only a double-layer structure, that is, the lower layer of the horizontal shift parking space mechanism is installed on the ground, and the layer frame is composed of three frame units 2 arranged in an array, and a lifting parking space mechanism is installed on each frame unit 2. It is not limited to this example, and multiple layers or other number of parking spaces can be used.

[0046] The transverse parking space mechanism includes a transverse guide rail 6 and a bottom tray 3 that translates left and right on the transverse guide rail 6 .

[0047] There are two transverse guide rails 6 and the length direction corresponds to the length direction of the frame body. The transverse guide rails 6 are fixedly installed on the ground. The two transverse guide rails 6 are respectively fixed near the front side and the parking side of the designed parking space. The transverse guide rails 6 have an I-shaped cross-section.

[0048] The bottom tray 3 includes side guards on both sides, and the side guards are welded and fixed to the bottom tray 3 by I-beams. The length direction of the bottom tray 3 corresponds to the length direction of the parking space design, and bearing seats are respectively provided at the four corners of the bottom tray 3. Wheel axles 4 are rotatably installed on the left and right sides of the bottom surface of the bottom tray 3 through the bearing seats, and the length direction of the wheel axle 4 is adapted to one side of the long side of the bottom tray 3. Track wheels 5 are respectively fixed at the edges of both ends of the wheel axle 4, and the track wheels 5 cooperate with the upper track crowns of the transverse guide rails 6 to realize the left and right walking constraint of the guiding bottom tray 3 along the transverse guide rails 6. The track wheels 5 are I-shaped, have a stable guiding effect on the stroke, and have a good load-bearing effect. A lower sprocket 7 is fixed to one end of the wheel axle 4, and a transverse motor 9 is fixedly installed above the bottom tray 3 on the same side or on the side of the retaining edge. An upper sprocket 8 is fixedly installed on the output shaft of the transverse motor 9. A transverse chain is wound between the upper sprocket 8 and the lower sprocket 7. Based on the transverse chain transmission, the wheel axle 4 is driven to rotate, thereby realizing the control and drive of the left and right transverse stroke of the bottom tray 3.

[0049] A first sensor is installed beside the transverse guide rail 6 , which may be a proximity sensor or a distance sensor, and is installed near the column 1 , so as to determine the position of the bottom tray 3 and thereby provide relevant data feedback to the transverse motor 9 .

[0050] The parking space lifting mechanism includes a driving shaft 10 mounted on the frame unit 2 , a lifting motor 11 , a drum 12 , a front steel wire rope 13 , a rear steel wire rope 14 , a first pulley 15 , a second pulley 16 , a third pulley 17 , and a lifting tray 20 .

[0051] The driving shaft 10 is one and extends along the width direction of the frame unit 2. The driving shaft 10 is rotatably installed on the front side of the frame unit 2. The two ends of the driving shaft 10 are coaxially fixed to the reels 12 on both sides to drive the double reels 12. The lifting motor 11 is fixedly installed in the middle position of the front side of the frame unit 2. A driving sprocket 18 is connected to the output shaft of the lifting motor 11. A driven sprocket 19 fixedly installed on the driving shaft 10 is provided below the driving sprocket 18, and a lifting chain is wound between the driving sprocket 18 and the driven sprocket 19.

[0052] The first pulley 15, the second pulley 16 and the third pulley 17 are respectively 2 groups and are symmetrically arranged on the left and right sides. The first pulley 15 and the second pulley 16 are installed side by side at the front positions of the left and right sides of the frame unit 2, and the third pulley 17 is installed at the rear positions of the left and right sides of the frame unit 2 and is flush with the second pulley 16.

[0053] There are two front steel wire ropes 13 and two rear steel wire ropes 14, and each drum 12 is wound with a front steel wire rope 13 and a rear steel wire rope 14 respectively. The front steel wire rope 13 passes over the first pulley 15 from the upper side and extends downward, and the end thereof is hooked and fixed to the edge of the lifting tray 20. The rear steel wire rope 14 passes over the second pulley 16 and the third pulley 17 in sequence and extends downward, and the end thereof is hooked and fixed to the edge of the lifting tray 20.

[0054] Based on the above structure, through the rotation of the lifting motor 11, the rotation of the drums 12 on both sides can be synchronously controlled to achieve synchronous retraction and release of the front steel wire ropes 13 and the rear steel wire ropes 14 on both sides, thereby completing the lifting or lowering control of the lifting pallet 20.

[0055] The center of the lifting tray 20 is provided with a strip opening 21 extending in the middle along its length direction. In order to facilitate the display of the central structure, the strip opening 21 in the attached figure is shown as widened. The strip opening 21 can reduce the weight of the lifting tray 20 and reduce the load on the lifting transmission structure during operation. The strip opening 21 is located in the center. Based on the constraint of the width of the tray when the vehicle enters the lifting tray 20, it can limit the wheels from entering the strip opening 21 (if a single side wheel enters the strip opening 21, its diagonal or target wheel must be outside the tray). The front side of the strip opening 21 is provided with a conical opening structure with the tip in front. Guide plates 22 are provided on both sides of the conical opening. The guide plates 22 are rubber strips. Side strips 23 are fixed on both sides of the lifting tray 20. The side strips 23 and the guide strips can assist in limiting the wheels and assisting the driver to drive the vehicle into the lifting tray 20 in the center.

[0056] A rectangular positioning opening 24 is provided in the center of the lifting tray 20 and crosses the strip opening 21. The positioning opening 24 is used to cooperate with the positioning platform 42 below for positioning. Based on the positioning opening 24, the strip opening 21 is divided into a front strip opening 21 (close to the front end of the vehicle and having a tapered opening structure) and a rear strip opening 21.

[0057] The front and rear sides of the positioning opening 24 are respectively provided with unpowered limiting mechanisms with symmetrical structures, and the limiting mechanism includes a main shaft 25 and a secondary shaft 26 extending along the width direction of the lifting pallet 20, and the secondary shaft 26 is close to the positioning opening 24 and is rotatably installed in the strip opening 21, the axes of the main shaft 25 and the secondary shaft 26 are horizontally parallel, and the secondary shaft 26 and the main shaft 25 are rotatably installed in the strip opening 21 in a sequence from near to far relative to the positioning opening 24, and the two ends of the main shaft 25 are respectively fixed with swing rods 27 perpendicular to the main shaft 25, and the end of the swing rod 27 away from the main shaft 25 is provided with a limiting shaft 28 parallel to the main shaft 25, and the outside of the limiting shaft 28 is rotatably sleeved with a roller sleeve, and the roller sleeve is a rubber sleeve, which is rotatably sleeved on the outside of the limiting shaft 28 and can be undamaged when in contact with the wheel. Strip grooves 29 are respectively provided on the lifting trays 20 on both sides of the strip opening 21. The size and position of the strip grooves are adapted to the dropped sleeve. When the end of the swing shaft swings downward, the sleeve and the limiting shaft 28 fall into the strip grooves, which facilitates the vehicle tires to pass through without rising and falling or obstruction.

[0058] A main connecting rod 30 is fixed at the center of the main shaft 25 , and a secondary connecting rod 31 is fixed at the center of the secondary shaft 26 .

[0059] The cam 35 is a substantially parallel rod 32 which is adapted to engage the cam 31 and engage the cam 32 with the aid of which the lever 32 is secured.

[0060] The sliding rod 32 can be loaded with a counterweight 36 as required. The counterweight 36 is made of a cast iron block. A slot is provided on the bottom side of the counterweight 36. The slot is movably plugged into the sliding rod 32. A fastening bolt 37 and a nut are passed through the side wall of the slot. When the counterweight 36 is inserted into the sliding rod 32, the fastening bolt 37 passes through the strip-shaped slide groove 33 and cooperates with the nut to fix the counterweight 36 on the sliding rod 32, and the fastening bolt 37 can prevent the passage of the slide bar 35. The above structure is simple and convenient, and it is easy to install, disassemble, and adjust the number and position of the counterweight 36. The counterweight 36 can not only increase the counterweight of the middle sliding rod 32, but also make the limit response more agile, and ensure the automatic lifting of the swing rod 27. At the same time, the counterweight block 36 can also adjust its position so that when the swing rod 27 falls, the counterweight block 36 is close to the position of the inner end of the slider, thereby blocking the slider from the maximum stroke position in the central direction through the fastening bolts 37 (which pass through the strip-shaped slide groove 33) on the counterweight block 36, constraining and assisting the sliding rod 32 to be in the middle position when it rises, thereby achieving counterweight balance.

[0061] Screw rods 38 are respectively provided at both ends of the sliding rod 32, penetrating the sliding rod 32 and being threadedly connected thereto. One end of the screw rod 38 is located in the strip-shaped slide groove 33. When the slide bar 35 slides toward the two ends of the sliding rod 32, the slide bar 35 can be limited by the inner end of the screw rod 38, thereby adjusting the farthest distance that the slide bar 35 slides toward the outer end of the sliding rod 32, thereby adjusting the height to which the limit shaft 28 is lifted.

[0062] Based on the above-mentioned limiting structure, as the lifting tray 20 rises, when it gradually separates from the mobile platform 39 below, the sliding rod 32 automatically sinks under the counterweight, and the swing rod 27 is driven to swing based on gravity, so that the limiting shaft 28 is lifted upward, and the wheels are respectively enclosed in front of the front wheel and behind the rear wheel to hinder movement, and the height of the limiting shaft 28 is adjustable, and the limiting height relative to the tire can be adjusted so that the limiting shaft 28 is located above the tire radius. When the tire contacts the limiting shaft 28 and the roller sleeve, the limiting effect can be enhanced. In addition, this structure does not hinder the vehicle when driving in and out, so it does not affect driving. For drivers with poor driving ability, it can reduce accidents caused by improper driving when driving in and out.

[0063] The above structure provides a method of realizing unpowered automatic limiting through a mechanical structure, which is not limited to the above structure. Electric control can be used to directly control the swing rod 27, and the swing rod 27 falls when the lifting tray 20 falls, and rises synchronously when the lifting tray 20 is raised.

[0064] A core weight mechanism is also provided below the bottom tray 3, and the core weight mechanism includes a moving platform 39, a translation guide rail 40, a rack 41, and a travel gear;

[0065] The movable platform 39 is located below the bottom tray 3 and does not interfere with the lateral movement of the bottom tray 3 .

[0066] There are two translation guide rails 40 and they are arranged in parallel in the same direction between the transverse guide rails 6. The translation guide rail 40 and the transverse guide rail 6 are arranged in parallel. The rack 41 is fixed in the same direction between the two translation guide rails 40. There is a slider slidingly matched on the translation guide rail 40. The slider is fixedly installed on the moving platform 39. The travel gear is rotatably installed under the moving platform 39 and is driven by the travel motor on the moving platform 39. Based on the above structure, the moving platform 39 is in the middle of the parking space and can have a left and right straight travel between each parking space. It can be moved to the corresponding position of any bottom parking space to achieve cooperation with the upper lifting pallet 20.

[0067] A positioning platform 42 corresponding to the size and position of the positioning opening 24 is provided in the center of the upper part of the mobile platform 39, and a bearing step 43 is provided between the positioning platform 42 and the mobile platform 39. A weighing module is installed on the bearing step 43. The weighing module can use an electronic sensor to weigh the fallen lifting tray 20 and obtain weighing data.

[0068] Based on the falling of the lifting tray 20 , the positioning platform 42 passes through and is located in the positioning opening 24 , and when the bottom surface of the lifting tray 20 contacts the bearing step 43 , the top surface of the positioning platform 42 is flush with the top surface of the lifting tray 20 .

[0069] A matching groove 44 is provided in the center of the positioning platform 42, which passes through the front and back of the positioning platform 42. The matching groove 44 is a through groove and passes through the front and rear end surfaces of the positioning platform 42 respectively. The width and position of the matching groove 44 correspond to the sliding rod 32. When the positioning platform 42 is located in the positioning opening 24, the sliding rod 32 falls into the matching groove 44 and is lifted up by the bottom of the matching groove 44, so that the swing rod 27 swings downward to be located in the strip opening 21, and the limiting shaft 28 is located in the strip groove 29.

[0070] By the lifting tray 20 falling down and cooperating with the positioning platform 42, the positioning opening 24 is filled and the swing rod 27 is dropped down, so as to facilitate the vehicle to enter or exit.

[0071] The front and rear sides of the bearing step 43 are respectively provided with locking blocks 45, and the top surface of the locking block 45 is provided with a wedge-shaped surface, the projection position of the wedge-shaped surface corresponds to the main shaft 25, and there are two locking blocks 45 on the same side and they are symmetrically arranged relative to the matching groove 44, so as to make room for the central space and facilitate the travel of the sliding rod 32. A vertical locking frame 46 is provided on the outer side of the locking block 45, and a connecting frame 47 connecting the two locking frames 46 on the same side is provided at the bottom end of the locking frame 46, and the connecting frame 47 is used to synchronize the extension and retraction of the two locking blocks 45. Two telescopic rods 48 are fixed to the connecting frame 47, and the telescopic rods 48 are located below the bearing step 43 and extend horizontally along the length direction of the lifting tray 20.

[0072] The front and rear sides of the movable platform 39 are respectively fixed with mounting tubes 49 which are telescopically matched with the telescopic rod 48. The length direction of the mounting tube 49 corresponds to the front-to-back direction of the bottom tray 3. A telescopic cavity is provided inside the mounting tube 49. A tube mouth is provided on the outer end face of the mounting tube 49 away from the movable platform 39. The telescopic rod 48 passes through the tube mouth and is telescopically matched with the mounting tube 49. A spring 50 is provided in the telescopic cavity. The spring 50 is installed between the inner end of the telescopic rod 48 and the tube mouth of the mounting tube 49. The spring 50 has an elastic force to retract the telescopic rod 48 into the mounting tube 49.

[0073] A mounting cavity is provided inside the mobile platform 39, which penetrates the mobile platform 39 from front to back. A double-headed cylinder 51 is fixedly installed in the mounting cavity. The double-headed cylinder 51 can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The two ends of the double-headed cylinder 51 are provided with cylinder rods 52 that are telescopically matched with the double-headed cylinder 51. The outer ends of the two cylinder rods 52 are provided with push plates 53, respectively. The push plates 53 are located in the telescopic cavity of the mounting tube 49 and are arranged near the inner end of the mounting cavity. The inner end of the telescopic rod 48 abuts against the push plate 53.

[0074] Based on the above structure, when the telescopic rod 48 is retracted into the installation tube 49 without external force, the locking block 45 is close to the positioning platform 42, and the wedge surface of the locking block 45 in the initial state corresponds to the position of the main shaft 25 of the lifting tray 20 (cooperating with the positioning platform 42). When the lifting tray 20 falls, the main shaft 25 moves downward and approaches the wedge surface. Based on the inclination of the wedge surface, the locking block 45 moves away from the positioning platform 42. After the main shaft 25 falls and enters below the locking block 45, the locking block 45 is reset to be above the main shaft 25, realizing the automatic locking of the mobile platform 39 and the lifting tray 20. When unlocking is required, the double-headed cylinder 51 is started, and the two cylinder rods 52 extend in the forward and backward directions respectively, so that the push plate 53 moves outward from the inner end of the installation cavity (the end close to the positioning platform 42), pushing the telescopic rod 48 out of the installation tube 49, so that the locking blocks 45 on the front and rear sides are respectively away from and staggered with the position of the main shaft 25, and the lifting tray 20 can be freely lifted and separated from the mobile platform 39.

[0075] The start-up of the double-headed cylinder 51 is connected to the weighing module data, and responds based on the data information fed back by the weighing module. Specifically, some thresholds are pre-set in the system, including the weight data H' of the lifting tray 20, the upper limit weight data that the lifting tray 20 can load is h, and the actual weighing data obtained by the weighing module is H:

[0076] When the weighing data H≤H', the double-headed cylinder 51 is in a standby state, and the cylinder rod 52 is retracted into the double-headed cylinder 51, without interfering with the telescopic rod 48;

[0077] When H'<weighing data H<h, the vehicle drives onto the dropped lifting tray 20 and is not overweight, the double-headed cylinder 51 is started and the telescopic rod 48 is kept extended, so the locking block 45 remains offset from the main shaft 25, and the lifting tray 20 can be lifted according to manual operation.

[0078] When the weighing data H≥h, the double-headed cylinder 51 is not started, the cylinder rod 52 is retracted into the double-headed cylinder 51, and the telescopic rod 48 is not interfered with. The locking block 45 continues to lock the lifting tray 20, which becomes a double mechanical insurance. Even if there is a manual operation error or a lifting operation error, the lifting tray 20 can be prevented from rising.

[0079] In the control of the fall of the lifting tray 20, it is necessary to ensure that the lifting tray 20 falls completely on the mobile platform 39, so that the weighing data can be obtained through the weighing module. The height of the descent can be preset, that is, the length of the wire rope released by the drum 12 controlled by the lifting motor 11. Because the wire rope will gradually elongate due to stretching and fatigue during use. Therefore, in the control of the fall of the lifting tray 20, the weighing data can be linked to the operation process of the lifting motor 11 in controlling the fall of the lifting tray 20 through upgrading, and the weight data H' of the lifting tray 20 can be loaded in advance. When the weighing data H is consistent with H', the lifting motor 11 stops running and the drum 12 stops releasing the wire rope.

[0080] At the same time, it is well known that there are strict standards for the elongation and maintenance of the wire rope used in the stereo garage. For the elongation limit of the wire rope, generally speaking, if the elongation of the wire rope reaches 5% of its original length, it should be scrapped. This is because the breaking force of the wire rope will decrease if it exceeds this elongation, which poses a safety hazard. Based on the above mode of feedback of the landing stop by weighing data, a label is further marked on the wire rope. In the case of the use of a non-destructive wire rope, when the lifting tray 20 is dropped from the second-floor parking space to the mobile platform 39, the length of the front wire rope 13 and the rear wire rope 14 to be released is ΔL, and when the lifting tray 20 is dropped on the mobile platform 39, the front original label is marked on the front wire rope 13 at the first pulley 15, and the rear original label is marked on the rear wire rope 14 at the third pulley 17, and the maximum allowable elongation is defined as Lx, which can be calculated based on ΔL (for example, 5% of ΔL, or the data is reduced according to regulations), or it can be defined by itself. A front critical label is added at a distance Lx from the front original label on the front steel wire rope 13, and a rear critical label is added at a distance Lx from the rear original label on the rear steel wire rope 14, and readers for the above labels are respectively installed on the first pulley 15 and the third pulley 17, so that when the front critical label and the rear critical label are read, an alarm is triggered, the lifting pallet 20 is stopped from descending, and the staff is reminded to replace the steel wire rope.

[0081] Furthermore, scale labels can be added at equal intervals between the front original label and the front critical label, and between the rear original label and the rear critical label, so that the actual elongation of the wire rope can be obtained and fatigue problems of the wire rope can be paid attention to in time.

[0082] Based on this upgrade, timely feedback on the fatigue status of the wire rope can be achieved. Compared with the existing method of only discovering problems through regular operation and maintenance inspections, this timely observation of fatigue and elongation can greatly improve the safety management level of the safe operation of the three-dimensional parking garage lifting and reduce accidents caused by wire rope operation and maintenance.

[0083] After the above-mentioned transformation of the lifting and overload weight of the three-dimensional parking garage, the parking process and method of the vehicle entering the parking system during the parking process includes at least the following processes:

[0084] When the bottom tray 3 of the lower layer is full and a new car needs to park, the upper vacant lifting tray 20 is activated, and the mobile platform 39 moves to the bottom of the activated lifting tray 20;

[0085] The lifting tray 20 falls to the positioning platform 42 and enters the positioning opening 24, the locking block 45 automatically locks the main shaft 25, and the sliding rod 32 rises under the lifting effect of the matching groove 44, so that the swing rod 27 falls, and the limit shaft 28 falls into the strip groove, so that the top surface of the lifting tray 20 has no structure that hinders the vehicle from driving in;

[0086] When the weighing data obtained by the mobile platform 39 is consistent with the weight of the lifting tray 20, the lifting of the lifting tray 20 stops, and the lifting tray 20 completes its fall;

[0087] When the vehicle enters the lifting tray 20 and the weighing data obtained by the mobile platform 39 is not overweight, the locking block 45 automatically moves forward and backward and staggers with the main shaft 25, and the mobile platform 39 unlocks the lifting tray 20.
