Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional garages, and in particular to a heavy-duty beam-type shelf based on a three-dimensional garage. Background Art

[0002] When transporting newly produced vehicles, automobile manufacturers will store them in automated high-bay warehouses in advance. The automated high-bay warehouses have multiple layers of heavy-duty beam shelves that can be lifted and lowered, which can achieve the effect of storing vehicles on multiple layers. However, when parking the vehicle on the heavy-duty beam shelves, the driver may cause the position of the vehicle on the heavy-duty beam shelves to deviate due to manual operation, and the vehicle may appear skewed or non-centered. This situation will make it inconvenient for the driver to open the door and get on and off the vehicle, and may also cause friction damage between the wheel hub and the heavy-duty beam shelves when the vehicle drives off the heavy-duty beam shelves. In addition, when heavy-duty beam racks transport and store vehicles, most of them use chains for transportation. However, the chains will wear out during long-term use, and lubricating oil and dust will mix to produce sludge, which will cause the transmission operation of the chain to jam. In addition, after long-term use, the chain will wear out and cause the pitch to lengthen, which will cause the transmission connection between the chain and the sprocket to loosen. When the sprocket drives the chain for transmission, it will cause the risk of tooth jumping and chain derailment. In severe cases, the heavy-duty beam rack will be unable to transport the vehicle, affecting the effect of the heavy-duty beam rack for three-dimensional storage of vehicles. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a heavy-duty beam-type shelf based on a stereo garage.

[0008] Furthermore, the two mounting grooves correspond to the positions of the through grooves of the fixed support plate, the two driving sprockets rotate inside the mounting grooves, the shape of the limit plate matches the shape of a single part of the chain, and an extended support bar is fixedly connected to the side wall of the through groove of the fixed support plate. The shape of the upper surface of the support bar matches the shape of the roller, and the roller rolls on the upper surface of the support bar.

[0009] Furthermore, the conveyor bars are evenly arranged along the transmission track of the chain, the length of the conveyor bars is adapted to the width of the through slot of the fixed support plate, and the side of the conveyor bars away from the block is provided with the same anti-slip groove as the fixed support plate.

[0010] Furthermore, two groups of cleaning components are provided at the bottom of the fixed support plate, and the cleaning components include two groups of fixing frames one fixedly connected to the bottom of the fixed support plate, and each group of fixing frames one is provided with two, and an oil pump is fixedly connected between the two fixing frames one of the two groups, and two brush racks are fixedly connected to the oil pump, and brush plates are clamped at the upper and lower ends of the two brush racks, and an oil pipe is fixedly connected between the bottom of the oil pump and the bottom of the brush rack.

[0011] Furthermore, the oil pumps are located on both sides of the interior of the chain, one end of the brush plate away from the brush holder contacts the chain, and the bottom end of the oil delivery pipe passes through the bottom of the brush holder.

[0012] Furthermore, two tensioning assemblies are provided at the bottom of the fixed support plate, and the tensioning assembly includes two fixing frames 2 fixedly connected to the lower surface of the fixed support plate, and a threaded rod is rotatably connected to the interior of the two fixing frames 2, and an adjusting bracket is threadedly connected to the two threaded rods. The two adjusting brackets are composed of a threaded ring and a sleeve, and a rotating shaft is rotatably connected between the two adjusting bracket sleeves. The middle of the rotating shaft is fixedly connected to a tensioning sprocket, the bottom end of each threaded rod is fixedly connected to a turntable, and the outer surface of each turntable is fixedly connected to a plurality of handles. The bottom of the side of the two fixing frames 2 away from each other is fixedly connected to the support platform, and each fixing frame 2 support platform is fixedly connected with a spring, the top of each spring is fixedly connected to a limiting rod, and the bottom end of each limiting rod is fixedly connected to a limiting block.

[0013] Furthermore, the end of the turning handle away from the turntable is configured to be bent upward, and a through hole is provided on the support platform of each fixed frame 2 for the limit rod to slide up and down. The bottom end of each limit rod passes through the through hole on the support platform of each fixed frame 2, and the bottom of the limit block fits into the outer surface of the turning handle. The bottom of the limit block is configured to be an arc groove, and the tensioning sprocket is connected to the chain transmission.

[0014] As described above, the beneficial effects of the heavy-duty beam-type rack based on the stereo garage in the present invention are as follows:

[0015] The conveying strips on the two conveying components are used to transmit the load in different directions, which can drive the front and rear wheels of the vehicle to move in different directions, thus achieving the effect of centering the vehicle. This prevents the wheels or hubs from being scratched when the vehicle leaves the fixed pallet, thus reducing the damage rate of new vehicles. At the same time, centering the vehicle can prevent the driver from having difficulty opening and closing the door when getting on and off the vehicle, thus providing convenience for the driver.

[0016] The lubricating oil is applied to the chain along the brush plate at the bottom, thereby achieving lubrication of the chain. Since the oil pump is close to the drive sprocket, the lubricating oil applied to the chain can timely lubricate the transmission connection between the drive sprocket and the chain when the chain is transmitting. The lubricating oil can form an oil film on the contact surface between the chain and the drive sprocket, thereby reducing the direct friction between the chain and the drive sprocket, reducing energy consumption, improving the transmission efficiency of the chain, and extending the service life of the chain and the drive sprocket.

[0017] By brushing the chain with a brush plate, the hard sludge formed by the oil and dust accumulated in the gaps of the chain joints can be cleaned to prevent the sludge from affecting the flexibility of the chain transmission. At the same time, it can also remove metal debris and other particles embedded in the chain caused by the operation of metal parts, preventing the wear of the clamp chain and the drive sprocket. At the same time, with the pumping effect of the oil pump, after the brush plate brushes away the old oil, the newly added lubricating oil can be more fully attached to the chain, improving the effect of forming an oil film on the chain;

[0018] By pushing the lower part of the chain downwards through the tensioning sprocket, the chain is gradually tightened, thereby ensuring that the transmission connection between the chain and the drive sprocket remains tight, preventing problems such as tooth jumping and chain derailment when the drive sprocket drives the chain for transmission, improving the stability of the drive sprocket driving the chain for transmission, further improving the stability of the conveyor bar during transportation, and eliminating chain swinging, reducing the noise generated by the swinging and the impact friction caused by the swinging. In addition, it can also ensure the effectiveness of the conveyor bar in correcting the vehicle transportation and avoid deviations in vehicle transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] The embodiments provided by the present invention will be described in detail below:

[0040] like Figures 1 to 10 As shown, a heavy-duty beam type shelf based on a stereo garage includes a heavy-duty beam 1, two heavy-duty beams 1 are provided, and a fixed support plate 2 is fixedly connected between the two heavy-duty beams 1 by bolts. The fixed support plate 2 has two through slots. The fixed support plate 2 is based on Figure 1 The right side end shown is set to be tilted downward, so that the vehicle can travel from the tilt of the fixed support plate 2 to the top of the fixed support plate 2. The fixed support plate 2 is provided with a plurality of anti-skid grooves arranged in a linear array. Figure 1 As shown, one of the heavy-duty crossbeams 1 is fixedly connected to two binocular vision sensors 6, and the two binocular vision sensors 6 correspond to the two through slots of the fixed support plate 2 respectively. The two binocular vision sensors 6 can measure the position of the vehicle wheels. A control panel 7 is fixedly connected to the heavy-duty crossbeam 1 on the side close to the binocular vision sensor 6. The position of the control panel 7 is convenient for the driver in the main driving seat to effectively view it. The control panel 7 has the functions of image display and voice broadcast. The image display can display the position of the vehicle in real time, and the voice broadcast can remind the driver. A conveying component for correcting the vehicle is provided in each of the two through slots of the fixed support plate 2;

[0041] It should be noted that the two conveying assemblies are respectively located in the two through slots of the fixed pallet 2, and the positions of the two through slots correspond to the front and rear wheels of a conventional vehicle, that is, the two conveying assemblies in the two through slots correspond to the front and rear wheels of a conventional vehicle.

[0042] To further illustrate, the heavy beam 1 is mainly installed in an existing automated stereoscopic warehouse. The automated stereoscopic warehouse has a suspension and lifting function, which enables the heavy beam 1 to move up and down, thereby achieving the effect of multi-layer stereoscopic placement of vehicles.

[0043] The conveying assembly includes two mounting grooves 31 opened on the side close to each other of the two heavy beams 1. The two mounting grooves 31 correspond to the through-groove positions of the fixed support plate 2. A servo motor group 32 is fixedly connected in the two mounting grooves 31. A driving sprocket 33 is fixedly connected to the output shaft of the two servo motor groups 32. The two driving sprockets 33 rotate inside the mounting grooves 31. A chain 34 is connected between the two driving sprockets 33. A plurality of groups of card blocks 35 are evenly connected to the chain 34. Each group of card blocks 35 is provided with two. The two card blocks 35 of each group are fixedly connected to each other. A conveyor bar 36, each conveyor bar 36 is fixedly connected to a limit plate 37 on one side close to the block 35, each limit plate 37 is located between the two blocks 35 of each group, the shape of the limit plate 37 is adapted to the shape of a single part of the chain 34, the block 35 and the limit plate 37 cooperate with each other to enable the conveyor bar 36 to be effectively fixed on the chain 34, each conveyor bar 36 is rotatably connected to rollers 38 at both ends, and an extended support bar is fixedly connected to the side wall of the through groove of the fixed support plate 2, the shape of the upper surface of the support bar is adapted to the shape of the roller 38, and the roller 38 rolls on the upper surface of the support bar.

[0044] It should be noted that the conveying bar 36 is evenly arranged along the transmission track of the chain 34, the length of the conveying bar 36 is adapted to the width of the through groove of the fixed pallet 2, and the side of the conveying bar 36 away from the block 35 is provided with the same anti-slip groove as the fixed pallet 2, which is used to increase the friction force in contact with the wheel hub. The length of the conveying bar 36 is longer than the diameter of the existing conventional vehicle wheel, so that the vehicle wheel can contact the conveying bar 36 after the vehicle is effectively parked on the fixed pallet 2.

[0045] Specifically, when it is necessary to store the newly produced vehicles in the automated warehouse, the driver reverses the vehicle from the inclined position of the fixed pallet 2 to the upper surface of the fixed pallet 2. During the driving of the vehicle, the binocular vision sensor 6 monitors in real time whether the wheels of the vehicle are located on the upper surface of the conveyor bar 36. When the vehicle has completely driven to the upper surface of the fixed pallet 2, the driver is reminded through the control panel 7 based on the detection of the binocular vision sensor 6. The reminders contained in the control panel 7 are mainly images and sounds. The image mainly shows whether the vehicle is effectively driving on the upper surface of the fixed pallet 2, and the sound reminds the driver based on the position of the vehicle. For example, when the vehicle has not completely driven to the upper surface of the fixed pallet 2, the control panel 7 reminds the driver to continue reversing through sound, thereby providing preliminary instructions to the driver for the operation of reversing into the warehouse, so that the vehicle after reversing into the warehouse can effectively stop when it drives to the upper surface of the fixed pallet 2. When the vehicle stops, the front and rear wheels of the vehicle can contact the conveyor bar 36, that is, the front and rear wheels of the vehicle can correspond to the two binocular vision sensors 6.

[0046] Next, after the vehicle has been parked on the upper surface of the fixed pallet 2, if the two binocular vision sensors 6 detect that the front and rear wheels of the vehicle are not aligned, that is, the two binocular vision sensors 6 detect that there is a difference in the distance between the front and rear wheels and the binocular vision sensors 6, and then detect that the vehicle is not parked neatly, that is, it is skewed. If the vehicle has this situation, it will affect the driver's getting on and off the vehicle and opening the door. In addition, when the subsequent vehicle drives off the fixed pallet 2, friction damage will occur between the wheel hub and the heavy beam 1, and then the control panel 7 will display a "Do not get off" pattern. Then, the controller controls the servo motor group 32 to start, and the output shaft of the servo motor group 32 will drive the drive sprocket 33 to rotate. When the drive sprocket 33 rotates, it will drive the chain 34 for transmission. The chain 34 will cooperate with the block 35 and the limit plate 37 to enable the conveying bar 36 to be driven synchronously for transmission. When the conveying bar 36 is transmitting, the rollers 38 at both ends of the conveying bar 36 will The conveying bar 36 is supported by the support bar and the conveying bar 36 is supported by the support bar so that the conveying bar 36 can be transmitted stably. The above description only describes a single conveying component. Because there are two conveying components, the servo motor groups 32 in the two conveying components drive the drive sprocket 33 to rotate in different directions, so that the chains 34 on the two conveying components and the conveying bar 36 are transmitted in different directions, thereby driving the front and rear wheels of the vehicle to move in different directions. Specifically, if the front wheel of the vehicle is to the left, the transmission direction of the conveying bar 36 in contact with the front wheel is to the right, otherwise the rear wheel of the vehicle is to the right, that is, the transmission direction of the conveying bar 36 in contact with the rear wheel is to the left, thereby achieving the effect of centering the vehicle, avoiding the situation where the wheels or wheel hubs of the vehicle are scratched when the vehicle drives out of the fixed pallet 2, reducing the damage rate of new cars, and at the same time, centering the transportation can prevent the problem of inconvenience in opening and closing the car door when the driver gets on and off the vehicle, providing convenience for the driver to get on and off the vehicle.

[0047] It should be noted that if the distance between the front and rear wheels of the vehicle and the two binocular vision sensors 6 is the same, but the vehicle is not parked in a centered position relative to the fixed pallet 2, that is, the wheels of the vehicle are not within the threshold of the detection distance of the binocular vision sensor 6, then the centering is performed in the same way as the above operation, but the difference is that the conveying bars 36 on the two conveying components convey the front and rear wheels of the vehicle synchronously in the same direction. When the vehicle wheels are conveyed to the threshold of the detection distance of the binocular vision sensor 6, stopping the conveyance of the vehicle wheels can also achieve the centering effect.

[0048] When the binocular vision sensor 6 detects that the two wheels are in the center position, the control panel 7 displays a "get off" pattern, and the entire conveying process of the conveying assembly is completed.

[0049] like Figure 2 、 Figures 9 to 12As shown, two groups of cleaning components for replenishing oil and cleaning the chain 34 are provided at the bottom of the fixed support plate 2. The cleaning components include two groups of fixing frames 41 fixedly connected to the bottom of the fixed support plate 2 by bolts. Each group of fixing frames 41 is provided with two. An oil pump 42 is fixedly connected between the two fixing frames 41 of the two groups. An oil tank is provided on one of the fixing frames 41 for storing lubricating oil. The oil tank and the oil pump 42 are connected by a pipeline. The oil pump 42 is located on both sides of the interior of the chain 34, that is, the oil pump 42 is close to the drive sprocket 3 3, which is used to lubricate the contact position between the chain 34 and the driving sprocket 33 in time after the lubricating oil is pumped out. Two brush racks 43 are fixedly connected to the oil pump 42. Brush plates 44 are clamped at the upper and lower ends of the two brush racks 43. The end of the brush plate 44 away from the brush rack 43 is in contact with the chain 34. An oil pipe 45 is fixedly connected between the bottom of the oil pump 42 and the bottom of the brush rack 43. The bottom end of the oil pipe 45 passes through the bottom of the brush rack 43. The brush plate 44 is provided with a hole adapted to the oil pipe 45 to facilitate the lubricating oil to fall from the brush plate 44.

[0050] Specifically, when the controller controls the servo motor group 32 to start, the oil pump 42 is also started synchronously by the controller. After the oil pump 42 is started, the lubricating oil in the oil tank can be extracted and pumped into the oil pipe 45, and then the lubricating oil is pumped downward through the oil pipe 45. The lubricating oil leaks out along the holes of the brush plate 44 at the bottom and is coated on the chain 34, thereby lubricating the chain 34. Because the oil pump 42 is close to the drive sprocket 33, the lubricating oil coated on the chain 34 can lubricate the transmission connection between the drive sprocket 33 and the chain 34 in time when the chain 34 is transmitting. The lubricating oil can form an oil film on the contact surface of the chain 34 and the drive sprocket 33, thereby reducing the direct friction between the chain 34 and the drive sprocket 33, reducing energy consumption, improving the transmission efficiency of the chain 34, and extending the service life of the chain 34 and the drive sprocket 33.

[0051] In addition, when the chain 34 is transmitting, the brush plate 44 is in contact with the chain 34, and the chain 34 can be cleaned by the brush plate 44, and the hard sludge formed by the oil and dust mixed with accumulated in the joint gaps of the chain 34 can be cleaned to prevent the sludge from affecting the flexibility of the chain 34 transmission. At the same time, it can also remove metal debris and other particles generated by the operation of metal parts embedded in the chain 34, and prevent the wear of the clamp chain 34 and the drive sprocket 33. At the same time, with the oil pumping effect of the oil pump 42, after the brush plate 44 brushes away the old oil, the newly added lubricating oil can be more fully attached to the chain 34, thereby improving the effect of forming an oil film on the chain 34.

[0052] It should be noted that during long-term use, the brush plate 44 may be condensed with lubricating oil due to accumulation. At this time, the staff can manually remove the brush plate 44 by pulling it downward to release the clamping relationship between the brush plate 44 and the brush holder 43, replace the new brush plate 44 and re-clamp it on the brush holder 43, thereby completing the replacement operation of the brush plate 44.

[0053] like Figure 2 、 Figure 4 、 Figure 9 、 Figure 10 、 Figure 13 and Figure 14 As shown, the bottom of the fixed support plate 2 is provided with two tensioning assemblies for adjusting the tension of the chain 34. The tensioning assembly includes two fixing frames 51 fixedly connected to the lower surface of the fixed support plate 2 by bolts. The interior of the two fixing frames 51 is rotatably connected to a threaded rod 52, and the bottom end of the threaded rod 52 passes through the bottom of the fixing frame 51. An adjusting bracket 53 is threadedly connected to the two threaded rods 52. The two adjusting brackets 53 are composed of a threaded ring and a housing. The openings of the two adjusting bracket 53 housings correspond to each other. A rotating shaft 54 is rotatably connected between the two adjusting bracket 53 housings. The middle part of the rotating shaft 54 is fixedly connected to a tensioning sprocket 55. The tensioning sprocket 55 is transmission-connected to the chain 34. The bottom end of each threaded rod 52 passing through the fixed frame 51 is fixedly connected to a turntable 56. The outer surface of each turntable 56 is fixedly connected to There are multiple turning handles 57 arranged in a circular array. The end of the turning handle 57 away from the turntable 56 is set to be bent upward, which is convenient for the staff to hold the turning handle 57 and rotate it. The bottom of the two fixed frames 51 on the side away from each other are fixedly connected to the support platform, and each fixed frame 2 51 support platform is fixedly connected with a spring 58. The top of each spring 58 is fixedly connected to a limiting rod 59. A through hole is provided on the support platform of each fixed frame 2 51 for the limiting rod 59 to slide up and down. The bottom end of each limiting rod 59 passes through the through hole on the support platform of each fixed frame 2 51, and one end of each limiting rod 59 passing through the through hole is fixedly connected to a limiting block 510. The bottom of the limiting block 510 is in contact with the outer surface of the turning handle 57, and the bottom of the limiting block 510 is set as an arc groove, which can limit the turning handle 57 when the limiting block 510 is in contact with the outer surface of the turning handle 57.

[0054] It should be noted that the two tensioning assemblies correspond to the chains 34 in the two conveying assemblies respectively, that is, the two tensioning assemblies can independently adjust the tension of the chains 34 in the two conveying assemblies.

[0055] Specifically, when the chain 34 is used for a long time, the pitch is elongated due to friction, which will cause the transmission connection between the chain 34 and the driving sprocket 33 to become loose. When the driving sprocket 33 drives the chain 34 for transmission, it will cause the risk of tooth jumping and chain derailment. Therefore, the chain 34 can be tensioned and adjusted by a tensioning assembly, which requires the lifting device in the existing automated warehouse to lift the overall position of the heavy beam 1 and the fixed pallet 2, so as to facilitate the adjustment of the staff. When the heavy beam 1 is adjusted to the appropriate height, the staff can enter the height below the fixed pallet 2. At this time, after holding the turning handle 57, the staff pushes the turning handle 57 and drives the turntable 56 to rotate. The turntable 56 will drive the threaded rod 52 to rotate inside the fixed frame 2 51, and the threaded rod 52 will drive the threaded connection thereto. The threaded ring of the adjusting support 53 moves downward, and the threaded ring of the adjusting support 53 drives the housing to move downward synchronously. The housing of the adjusting support 53 drives the rotating shaft 54 to move downward. When the rotating shaft 54 moves downward, it pushes the lower part of the chain 34 downward through the tensioning sprocket 55, so that the chain 34 is gradually tightened, thereby ensuring that the transmission connection between the chain 34 and the driving sprocket 33 remains in a tight state, preventing the problems of tooth jumping and chain derailment when the driving sprocket 33 drives the chain 34 to transmit, improving the stability of the transmission when the driving sprocket 33 drives the chain 34, further improving the stability of the conveying bar 36 during transportation, and eliminating the swinging of the chain 34, reducing the noise generated by the swinging and the impact friction caused by the swinging, and also ensuring the effectiveness of the conveying bar 36 in correcting the automobile transportation, avoiding deviations in automobile transportation.

[0056] When the staff pushes the turning handle 57 to rotate, the limit block 510 will be continuously pushed, so that the limit block 510 drives the limit rod 59 to move upward. When the limit rod 59 moves upward, the spring 58 will be stretched. When the turning handle 57 passes the limit block 510 or the turning handle 57 is not in contact with the limit block 510, the limit rod 59 drives the limit block 510 to move downward under the elastic reset action of the spring 58. After adjusting the tension of the tensioning sprocket 55 on the chain 34, the turning handle 57 needs to be aligned with the limit block 510, so that the limit block 510 can effectively contact and fit with the turning handle 57. The turning handle 57 can be restricted by the limit block 510 to prevent loosening after adjusting the tension of the tensioning sprocket 55 on the chain 34, thereby improving the stability of the tensioning sprocket 55 on the chain 34 and ensuring that the tensioning sprocket 55 effectively tightens the chain 34.

[0057] It should be noted that if the staff pushes the handle 57 to rotate and the handle 57 is not aligned with the limit block 510, the staff can push the handle 57 closest to the limit block 510 at a small angle to make the handle 57 rotate at a small angle with the turntable 56 as the axis. When the handle 57 is rotated to the position corresponding to the limit block 510, the limit block 510 will contact and fit with the handle 57, and the handle 57 can also be limited to ensure the stability of the tensioning sprocket 55 in adjusting the tension of the chain 34.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
