Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of gravity energy storage, and particularly relates to a gravity energy storage vertical transportation car structure and a gravity block loading and unloading method. BACKGROUND

[0002] As one of the energy storage methods, the principle of gravity energy storage is to convert electric energy into potential energy by an electric motor, lift the gravity block to a certain height, and then lower the gravity block when the power system needs electric energy to drive the generator to convert potential energy into mechanical energy, and then convert the mechanical energy into electric energy through the rotor cutting magnetic lines.

[0003] In the existing gravity energy storage technology, there are various implementation modes for gravity block transportation, such as transportation by winch traction steel rope and gear rack, etc. In any transportation structure, the car is an important execution component for realizing the vertical lifting of heavy objects. The stability of the car during operation and the stability of the gravity block in the car and the loading and unloading efficiency of the gravity block have important influence on the entire energy storage system. However, there are few patents on this part of technology, and how to ensure the stable work and efficiency improvement of the car and the gravity block still needs to be further explored. SUMMARY

[0004] The present application discloses a gravity energy storage vertical transportation car structure and a gravity block loading and unloading method, which aims to solve the technical problem that the stability of the car and the gravity block in the car and the work cooperation efficiency of the two need to be improved during the gravity energy storage process.

[0005] To solve the above technical problems, the technical scheme adopted by the present application is as follows:

[0006] A gravity energy storage vertical transportation car structure, comprising a car and a bearing unit,

[0007] The car is provided with a bearing unit,

[0008] The bearing unit comprises a mounting frame, a roller assembly and a roller coordination assembly, the mounting frame is arranged on the car, and the mounting frame is provided with the roller assembly,

[0009] The roller assembly comprises a first roller group, a second roller group and a third roller group arranged in sequence from the outer side to the inner side of the car, the first roller group and the third roller group are provided with the roller coordination assembly between the two roller groups and the mounting frame, or the first roller group, the second roller group and the third roller group are provided with the roller coordination assembly between the three roller groups and the mounting frame, for coordinating the relative height between the first roller group, the second roller group and the third roller group.

[0010] The application adjusts the relative height of different roller groups in the car by roller coordination assembly, so as to assist the gravity block to enter and exit the car and preliminarily limit the gravity block when the gravity block is in the car.

[0011] Specifically, when the gravity block enters the car, the roller coordination assembly adjusts the relative height of the first roller, the second roller and the third roller, so that the roller surface gradually inclines downward from the outside to the inside of the car, facilitating the gravity block to slide into the car; when the gravity block enters the car, the roller coordination assembly adjusts the height of the outermost roller of the first roller to be higher than the inner roller, so that the gravity block is preliminarily limited, preventing it from sliding out of the car, or the height of the second roller group in the middle can be adjusted to be lower, and the outer roller of the first roller group and the inner roller of the third roller group close to the car are adjusted to be higher, so as to assist locking to prevent the gravity block from sliding in the car; when the gravity block exits the car, the roller coordination assembly adjusts the relative height of the first roller group, the second roller group and the third roller group, so that the roller surface gradually inclines downward from the inside to the outside of the car, facilitating the gravity block to slide out of the car, thereby facilitating unloading; the improvement of loading and unloading and the limitation of the gravity block realize the smooth progress of the energy storage process, improve the efficiency and improve the stability of the gravity block.

[0012] The application provides a car structure for vertical transportation of gravity energy storage, the roller assembly includes two rows of roller groups, and a locking piece is arranged between the two rows of roller groups; when the gravity block reaches the inside of the car, the locking piece can be positioned and locked with the gravity block.

[0013] The application adjusts the relative height of different roller groups in the car by roller coordination assembly, so as to assist the gravity block to enter and exit the car and preliminarily limit the gravity block when the gravity block is in the car.

[0014] The application provides a car structure for vertical transportation of gravity energy storage, the roller assembly includes two rows of roller groups, and a locking piece is arranged between the two rows of roller groups; when the gravity block reaches the inside of the car, the locking piece can be positioned and locked with the gravity block.

[0015] When the gravity block is in the car, the gravity block is prone to shaking during vertical operation of the car in the shaft, affecting the stability of the whole car, the application preliminarily limits the gravity block by roller height matching, and the locking piece is more easily positioned and locked with the gravity block on the basis of the preliminary limitation, so as to improve the locking efficiency and ensure the stable operation of the gravity block.

[0016] The application preferably relates to a gravity energy storage vertical transportation car structure, wherein the locking member comprises a fixed plate arranged on the mounting frame and a jacking mechanism arranged below the fixed plate, the fixed plate is provided with a socket and / or a protrusion, and the socket and / or the protrusion are matched with the protrusion and / or the socket arranged on the bottom of the gravity block to realize locking.

[0017] The locking member and the gravity block are locked through the plug-in structure, specifically, when the fixed plate is provided with the socket, the bottom of the gravity block is provided with the protrusion, when the fixed plate is provided with the protrusion, the bottom of the gravity block is provided with the socket, and the protrusion and the socket are matched to realize the limiting in the transverse direction.

[0018] Preferably, the four corners of the fixed plate are provided with tapered holes, and the bottom of the gravity block is provided with tapered columns matched with the tapered holes.

[0019] The roller assembly of the application is divided into two rows, and the locking member capable of jacking is arranged in the space between the two rows of rollers. The movement tendency of the gravity block mainly comes from the transverse force, such as the horizontal pushing force, the pulling force or the vibration generated force, that is, the direction of the force is parallel to the ground. At this time, the fixed plate acts as the main force bearing member and needs to directly bear and offset these transverse forces to prevent the horizontal movement of the gravity block. The jacking force generated by the jacking mechanism at the bottom of the fixed plate is not directly opposed to the transverse force, but the tapered column is "jacked into" the tapered hole of the fixed plate. Due to the slope (taper) of the tapered column, the contact area between the column and the hole wall increases with the increase of the insertion depth, forming a "wedge effect", which is more and more firm with the jacking, and the friction force and the constraint force are generated by the wedge effect of the tapered structure. Due to the design of the inclination angle of the tapered column, a small jacking force can generate a large positive pressure in the transverse direction, thereby limiting the movement of the gravity block, and the load bearing of the gravity block is mainly completed by the rollers in contact with the gravity block.

[0020] The application preferably relates to a gravity energy storage vertical transportation car structure, wherein a limiting block is arranged at the rear side of the car, and the limiting block and the first roller group cooperate to preliminarily limit the gravity block when the gravity block enters the car.

[0021] When the gravity block enters the car, the inner side wall is in contact with the limiting block, and the height of the outer roller of the first roller group is higher than that of the other rollers of the first roller group and is higher than that of the second roller group and the third roller group, thereby forming a high-position roller, so that the gravity block sinks to the low-position roller, and a limiting space is formed between the limiting block and the outer roller, thereby preventing the gravity block from moving along the direction of entering and exiting the car.

[0022] Preferably, the limiting block and the high-position roller of the first roller group are matched with the locking member, when the gravity block abuts against the limiting block and the limiting block and the high-position roller preliminarily limit the gravity block, the fixed plate below the gravity block is matched with the gravity block to complete the locking under the driving of the jacking mechanism, since the preliminary limiting is performed first, the locking action can be more accurate and efficient.

[0023] Preferably, as for the limiting and locking of the gravity block, the second roller group can be in the low position, the rollers of the first roller group and the third roller group close to the second roller group are also in the low position, so that the high-position rollers of the first roller group and the third roller group are matched to limit the gravity block, wherein the heights of the intermediate low-position rollers can be equal, so that the low-position rollers jointly bear the gravity block, in addition, the intermediate low-position rollers can be gradually raised from the middle to the two ends to form an arc surface, from the side, the gravity block is on the vertically symmetrical arc surface, under the action of gravity, the gravity block finally is in the middle position, so as to realize that the center of the gravity block and the center of the roller are in the same plane, improve the alignment accuracy of the gravity block and the fixed plate and then improve the locking effect, in this case, the limiting and locking of the gravity block can be realized without the rear limiting block.

[0024] Preferably, at least two limiting blocks are arranged at the rear side of the car, i.e. the final parking end of the gravity block, and are symmetrically distributed on both sides of the car width direction centerline to ensure that the gravity block completely enters the car to contact the limiting block, and the locking member completes the locking.

[0025] Preferably, a gravity storage energy vertical transportation car structure is provided, and the car is provided with transverse blocking members on both sides, which are located between adjacent two rollers and are used for limiting the gravity block in the transverse direction.

[0026] The transverse blocking members are respectively installed at the outermost ends of the left and right rollers, preferably, the contact surface of the transverse blocking member with the gravity block is smooth and has a round corner for guidance, more preferably, the transverse blocking member can be a vertically arranged roller to limit the gravity block in the left-right direction, so that the left and right blocking members can play a limiting role when the gravity block just enters or exits the car, so that the gravity block always remains stable and does not tilt; meanwhile, the transverse blocking member is matched with the two limiting blocks and the outer high-position roller arranged at the rear side of the car to limit the gravity block in the front-rear direction and the left-right direction, and then the bottom is locked, thereby improving the accuracy and efficiency of the locking of the gravity block.

[0027] Specifically, the scheme realizes transverse full-range limiting through the left and right continuous blocking members, which play a limiting role from the beginning when the gravity block enters the car, avoiding initial deviation, and realizes accurate positioning in the transverse and longitudinal directions in combination with the rear positioning limiting block, so as to finally ensure that the four conical surfaces below the gravity block are concentric with the four corners of the car locking device, thereby improving the locking efficiency.

[0028] The application provides a gravity energy storage vertical transportation car structure.

[0029] The car is meshed with a rack in a shaft through a gear of a drive system, a drive motor drives the gear to rotate to move on the rack, and vertical movement of the car in the shaft is realized.

[0030] Preferably, the gear floating assembly comprises a one-way movable ball type support and a telescopic double-cross shaft universal coupling, the one-way movable ball type support is vertically installed between the car and a gear bearing seat, and the telescopic double-cross shaft universal coupling is transversely installed between a speed reducer and a gear shaft, and is used for realizing position floating between the gear and the car.

[0031] After the position floating of the gear, the transmission of vertical load between the gear and the car should be met, meanwhile, the transmission of torque between the gear shaft and the output shaft of the car speed reducer should be ensured, and self-adapting guiding and accurate meshing between the gear and the rack should be realized.

[0032] Preferably, a rack back wheel assembly is connected to the gear bearing seat, and self-adapting guiding and accurate meshing between the gear and the rack are realized through cooperation of the rack back wheel assembly and the gear floating assembly.

[0033] The application provides a gravity energy storage vertical transportation car structure, a guide rail is arranged in a shaft in which the car runs, the car is provided with a guide assembly matched with the guide rail, a holding structure is arranged on the guide assembly, and the holding structure is used for holding the guide rail when the car needs to stop.

[0034] A method for loading and unloading a gravity block, comprising the following steps:

[0035] Step 1: After the car arrives at the corresponding floor for loading the gravity block, stop running, start the roller coordination assembly of the first roller group to rise, and the roller coordination assembly of the third roller group to lower, so that the entire roller assembly forms a downward inclined roller surface from the outside to the inside of the car;

[0036] In step 1, the roller coordination assemblies of the first, second and third roller groups can also be started simultaneously to form a downward inclined roller surface from the outside to the inside of the car;

[0037] Step 2: Push the gravity block into the car, and when the gravity block enters the car, the rollers of the first roller group near the second roller group are lowered to the height of the second roller group, the third roller group is raised to the height of the second roller group, and the rollers on the outside of the first roller group are higher than the rollers on the inside to limit the gravity block;

[0039] Step 3: Jack up the fixed plate so that the gravity block is locked with the fixed plate to complete the loading of the gravity block in the car;

[0040] Step 4: After the car arrives at the corresponding floor for unloading the gravity block, stop running, start the roller coordination assembly of the first roller group to lower, and the roller coordination assembly of the third roller group to rise, so that the entire roller assembly forms a downward inclined roller surface from the inside to the outside of the car;

[0041] In step 4, the roller coordination assemblies of the first, second and third roller groups can also be started to form a downward inclined roller surface from the inside to the outside of the car;

[0042] Step 5: The jacking mechanism below the fixed plate is retracted to release the locking of the gravity block by the fixed plate;

[0043] Step 6: Drive the gravity block to move outward from the car to complete the unloading of the gravity block in the car;

[0044] The above loading and unloading processes are cyclically operated to realize the vertical transportation of the gravity block.

[0045] In the step 2, when the gravity block abuts against the limiting block in the car, the lifting mechanism is triggered to lift the locking part to lock the gravity block; and in the step 5, when the gravity block is separated from the limiting block, the lifting mechanism is triggered to lower the locking part to release the locking of the gravity block.

[0046] In conclusion, the present application has the following advantages:

[0047] 1. The present application adopts different roller groups to assist the gravity block to enter and exit the car, and uses the outer high roller or the inner and outer high rollers to preliminarily limit the gravity block when the gravity block is in the car, thereby ensuring efficient and smooth loading and unloading and improving the stability of the lifted gravity block.

[0075] Embodiment 1

[0076] A gravity energy storage vertical transportation car 1 structure, as shown in the figure, comprising a car 1 and a bearing unit, Figures 1-4 The car 1 is provided with a bearing unit,

[0077] The car 1 is provided with a bearing unit,

[0078] The bearing unit comprises a mounting frame 2, a roller assembly 7 and a roller coordination assembly 3, the mounting frame 2 is arranged on the car 1, and the roller assembly is mounted on the mounting frame 2,

[0079] The roller assembly 7 comprises a first roller group 71, a second roller group 72 and a third roller group 73 distributed in turn from the outside to the inside of the car 1, the roller coordination assembly 3 is arranged between the rollers of the first roller group 71 and the third roller group 73 and the mounting frame 2, or the roller coordination assembly 3 is arranged between the first roller group 71, the second roller group 72, the third roller group 73 and the mounting frame 2, for coordinating the relative height between the first roller group 71, the second roller group 72 and the third roller group 73.

[0080] The present application adjusts the relative position height between different rollers through the roller coordination assembly 3 arranged in the car 1, thereby assisting the gravity block 11 to enter and exit the car 1, and preliminarily limiting the gravity block 11 when it is located in the car 1.

[0081] Specifically, when the gravity block 11 enters the car 1, the roller coordination assembly 3 coordinates the relative height of the first roller group 71, the second roller group 72 and the third roller group 73, so that the roller surface gradually inclines downward from the outside to the inside of the car 1, facilitating the sliding of the gravity block 11 into the car 1; after the gravity block 11 enters the car 1, the roller coordination assembly 3 coordinates the roller on the outermost side of the first roller group 71 to be higher than the roller on the inner side, thereby preliminarily limiting the gravity block 11 and preventing it from sliding out of the car 1; when the gravity block 11 exits the car 1, the roller coordination assembly 3 coordinates the relative height of the first roller group 71, the second roller group 72 and the third roller group 73, so that the roller surface gradually inclines downward from the inside to the outside of the car 1, facilitating the sliding of the gravity block 11 out of the car 1, thereby facilitating unloading. The smooth progress of the energy storage process is realized through the improvement of loading and unloading and the limitation of the gravity block 11, the efficiency is improved, and the stability of the gravity block 11 is improved.

[0082] As shown in the figure, Figure 3 And 4As shown in the figure, the roller assembly of the roller assembly includes a roller bracket 70 and a roller above the roller bracket 70, the roller bracket 70 is slidingly installed on the mounting frame 2, the roller assembly 3 includes a lifting driving device, the roller bracket 70 of the roller assembly 7 which needs to be adjusted in height is provided with the lifting driving device between the mounting frame 2, for driving the roller above to lift, in particular, the bottom of the lifting driving device is connected with the frame of the car 1, the upper end is connected with the roller bracket 70 through the mounting frame 2, and the roller bracket 70 can move up and down relative to the mounting frame 2 under the driving of the lifting driving device.

[0083] The present application can realize various height matching of the roller group by setting the lifting driving device below the roller which needs to be adjusted in height, such as one side high and one side low to facilitate the gravity block 11 to enter and exit, or both sides high and the middle low to facilitate the gravity block 11 to be limited or positioned, or the height of the entrance side of the car 1 is high to limit the gravity block 11.

[0084] In the embodiment, the setting mode of the roller bracket 70 and the mounting frame 2 is specifically as shown in the figure Figure 4 As shown in the figure, the roller is connected with the roller bracket 70 through the roller mounting seat, the mounting frame 2 is provided with a mounting groove, and the roller bracket 70 can move up and down in the mounting groove of the mounting frame 2 under the action of the roller assembly 3 at the bottom of the roller bracket 70, so as to realize the height adjustment of the roller.

[0085] Embodiment 2

[0086] The difference between the embodiment and the embodiment 1 is that, as shown in the figures Figure 5 , Figure 6 and Figure 7 As shown in the figure, the roller assembly 7 includes two rows of roller groups, and a locking piece 8 is arranged on the frame body between the two rows of roller groups, and the locking piece 8 can be positioned and locked with the gravity block 11 after the gravity block 11 reaches the inside of the car 1.

[0087] When the gravity block 11 is located in the car 1, due to the low friction of the roller, the gravity block 11 is easy to shake when the car 1 runs vertically in the shaft, which affects the stability of the whole car 1, the present application realizes preliminary limiting through the height matching of the roller, and the locking piece 8 is more easily positioned and locked with the gravity block 11 on the basis of the preliminary limiting, which improves the locking efficiency and ensures the stable operation of the gravity block 11.

[0088] In the embodiment, the locking piece 8 includes a fixed plate 80 arranged on the frame of the car 1 and a jacking mechanism 82 arranged below the fixed plate 80, the jacking mechanism 82 can adopt a screw rod spiral lifter, the fixed plate 80 is provided with a thimble and / or a protrusion, and the thimble and / or the protrusion are matched with the protruding block and / or the thimble arranged at the bottom of the gravity block 11 to be positioned and locked.

[0089] The locking member 8 and the gravity block 11 are locked by a plug-in structure. Specifically, when a plug hole is arranged on the fixed plate 80, a protrusion is arranged on the bottom of the gravity block 11; when a protrusion is arranged on the fixed plate 80, a plug hole is arranged on the bottom of the gravity block 11, and the protrusion and the plug hole are matched to realize the limiting in the transverse direction.

[0090] In the embodiment, as shown in Figure 6 and Figure 10 , the four corners of the fixed plate 80 are provided with tapered holes 81, and the bottom of the gravity block 11 is provided with tapered columns 110 matched with the tapered holes 81.

[0091] In the embodiment, as shown in Figure 2 , in each column of the roller assembly 7, the number of rollers of the first roller group 71 and the third roller group 73 is 5, and the number of rollers of the second roller group 72 is 2.

[0092] The roller assembly of the application is divided into two columns, and the locking member 8 capable of being jacked up is installed by using the space between the two columns of rollers. The moving tendency of the gravity block 11 mainly comes from the transverse force, such as the horizontal pushing force, the pulling force or the force generated by vibration, that is, the direction of the force is parallel to the ground. At this time, the fixed plate 80 as the main force bearing member needs to directly bear and offset these transverse forces to prevent the horizontal movement of the gravity block 11. The jacking mechanism 82 at the bottom of the fixed plate 80 generates a jacking force, which is not directly opposed to the transverse force, but by jacking, the tapered column 110 is “inserted” into the tapered hole 81 of the fixed plate 80. Due to the slope of the taper, that is, the taper, the contact area between the column and the groove wall increases with the increase of the insertion depth, forming a “wedge effect”, which is more and more firm, and the wedge effect of the tapered structure generates friction and restraint force. Due to the design of the inclination angle of the tapered column 110, a smaller jacking force can generate a larger positive pressure in the transverse direction, thereby limiting the movement of the gravity block 11.

[0093] Embodiment 3

[0094] The difference between the embodiment and the embodiment 2 is that, as shown in Figure 5 , Figure 6 and Figure 8 , the rear side of the car 1 is provided with a limiting block 9. When the gravity block 11 enters the car 1, the limiting block 9 cooperates with the first roller group 71 to preliminarily limit the gravity block 11.

[0095] When the gravity block 11 enters the cabin 1, the rear side wall contacts the limiting block 9, and the height of the outer roller of the first roller group 71 is higher than that of the other rollers of the first roller group 71 and the heights of the second roller group 72 and the third roller group 73, forming a high roller, so that the gravity block 11 sinks to the low roller, and a limiting space is formed between the limiting block 9 and the outer roller, preventing the gravity block 11 from moving in the direction of entering and exiting the cabin 1.

[0096] In the embodiment, the limiting block 9 and the high roller of the first roller group 71 are matched with the locking member 8. When the gravity block 11 abuts against the limiting block 9 and the limiting block 9 and the high roller preliminarily limit the gravity block 11, the fixed plate 80 below the gravity block 11 is matched with the gravity block 11 upwardly under the driving of the jacking mechanism 82 to complete locking. Since preliminary limiting is performed first, the locking action can be more accurate and efficient.

[0097] In the embodiment, two limiting blocks 9 are arranged at the rear side of the cabin 1, i.e., the final parking end of the gravity block, and are symmetrically distributed on both sides of the width direction center line of the cabin 1 to ensure that the gravity block completely enters the cabin 1 to contact the limiting block 9, and the locking member 8 completes locking.

[0098] When the gravity block 11 contacts the rear side limiting block 9, the four conical surfaces below the gravity block 11 have a concentricity error of ≤0.5mm with the four corners of the locking device of the cabin 1, directly meeting the locking docking requirements. By accurately calculating the length of the gravity block 11, the roller spacing, and the position of the limiting block 9, the center coordinates of the bottom conical surface of the gravity block 11 and the preset coordinates of the locking device are ensured to have a deviation of ≤0.3mm when the gravity block 11 contacts the rear side limiting block 9.

[0099] Embodiment 4

[0100] The difference between the embodiment and embodiment 3 is that the limiting block 9 is two or three or more, and a buffer member such as a rubber pad is arranged at the end of the limiting block 9 in contact with the gravity block 11. When the gravity block 11 slides along the roller to the inside of the cabin 1, the buffer member can effectively prevent the gravity block 11 from impacting the cabin 1 in an extreme case.

[0101] Embodiment 5

[0102] The difference between the embodiment and embodiment 3 is that, as shown in Figure 8 and Figure 9 The lateral blocking member 10 is arranged on both sides of the cabin 1 and located between adjacent two rollers, for limiting the gravity block 11 in the lateral direction.

[0103] In the embodiment, the lateral blocking piece 10 is smooth and rounded in contact with the gravity block 11, or the lateral blocking piece 10 can also be a vertically arranged roller to limit the left-right direction of the gravity block 11, so that the lateral blocking piece 10 on the left and right sides of the gravity block 11 can immediately play a limiting role when the gravity block 11 just enters or exits the car 1, so that the gravity block 11 always remains stable and does not tilt; at the same time, the lateral blocking piece 10 cooperates with the limiting block 9 installed at the rear side of the car 1 and the outer high roller to limit the front-back direction and the left-right direction of the gravity block 11, and then is locked at the bottom, improving the accuracy and efficiency of the locking of the gravity block 11.

[0104] In the embodiment, the lateral blocking piece 10 is smooth and rounded in contact with the gravity block 11, or the lateral blocking piece 10 can also be a vertically arranged roller to limit the left-right direction of the gravity block 11, so that the lateral blocking piece 10 on the left and right sides of the gravity block 11 can immediately play a limiting role when the gravity block 11 just enters or exits the car 1, so that the gravity block 11 always remains stable and does not tilt; at the same time, the lateral blocking piece 10 cooperates with the limiting block 9 installed at the rear side of the car 1 and the outer high roller to limit the front-back direction and the left-right direction of the gravity block 11, and then is locked at the bottom, improving the accuracy and efficiency of the locking of the gravity block 11.

[0105] In the embodiment, the lateral blocking piece 10 is installed at the gap between the rollers, and the deviation is corrected by arc surface guidance or vertical roller surface guidance, wherein a lateral deviation of ±10mm is allowed. As the gravity block 11 moves, the present application is designed to be 0.245m / step, and the limiting action of the next lateral blocking piece 10 is triggered every time the gravity block 11 enters a roller spacing, forming a step-by-step constraint, controlling the lateral deviation within 3-5mm, and ensuring stable movement without tilting.

[0106] Another way to constrain the lateral displacement in the embodiment is to set a texture with increased friction coefficient on the surface of the roller or wrap a layer of rubber material, relying on the friction force of the contact plane to provide a lateral restraining force.

[0107] Embodiment 6

[0108] The difference between the present embodiment and the above embodiments is that, as shown in Figure 1 , Figure 5 and Figure 11 , the car 1 is provided with a driving system 5, the driving system 5 is two sets, symmetrically distributed below the mounting frame 2, the driving system 5 includes a driving motor 501, a speed reducer 502 and a driving gear 504, the driving motor 501 is connected to the gear 504 through the speed reducer 502, the driving gear 504 is engaged with the rack 13 in the shaft, thereby driving the car 1 to ascend and descend along the shaft, the gear 504 is connected with a gear floating assembly, and the gear floating assembly is used to adjust the stable cooperation between the driving gear 504 and the rack 13.

[0109] The car 1 is engaged with the rack 13 in the shaft through the gear 504 of the drive system 5, the drive motor 501 drives the gear 504 to rotate to move on the rack 13, so as to realize the vertical operation of the car 1 in the shaft. Due to the influence of factors such as manufacturing error, installation error, structural stress deformation and the like, there is an inevitable relative position deviation between the car 1 and the rack. In order to realize the accurate transmission of the gear and the rack, the correct installation distance is needed to ensure the reasonable meshing clearance between the gears and to avoid the relative angle deviation between the gears and the rack. The transmission between the car 1 and the rack 13 is realized through the pinion 504, so the car 1, the pinion 504 and the rack 13 are analyzed. In order to ensure the reliability and high efficiency of the gear and rack transmission, the interference of the relative position deviation between the car 1 and the rack 13 on the gear and rack transmission should be eliminated, so that the gear and rack transmission can adapt to various relative position deviations, and therefore the position floating of the gear 504 needs to be considered, and the gear floating assembly is set.

[0110] The gear floating assembly comprises a one-way movable ball type support 505 and a telescopic double cross shaft universal coupling 503. The one-way movable ball type support 505 is vertically installed between the car 1 and the gear bearing seat 506, and the telescopic double cross shaft universal coupling 503 is transversely installed between the speed reducer 502 and the gear shaft, so as to realize the position floating between the gear 504 and the car 1.

[0111] After the position floating of the gear 504, the transmission of the vertical load between the gear 504 and the car 1 should be met, and at the same time, the transmission of the torque between the gear shaft of the gear 504 and the output shaft of the speed reducer 502 in the car 1 should be ensured, and the self-adaptive guiding and accurate meshing between the gear 504 and the rack 13 should be realized. The one-way movable ball type support 505 and the telescopic double cross shaft universal coupling 503 are combined to realize the position floating between the gear 504 and the car 1. The one-way movable ball type support 505 comprises three rotational degrees of freedom and one transverse movement degree of freedom, and the telescopic double cross shaft universal coupling 503 comprises five degrees of freedom.

[0112] The rack back wheel assembly 12 is connected to the gear bearing seat 506, and the self-adaptive guiding and accurate meshing of the gear 504 and the rack are realized through the cooperation of the rack back wheel assembly 12 and the above-mentioned gear floating assembly.

[0113] In this embodiment, the car 1 is fastened to the upper support plate of the one-way movable ball-type support 505, the gear bearing seat 506 is fastened to the lower support plate of the one-way movable ball-type support 505, there is only one rotational degree of freedom between the gear bearing seat 506 and the gear 504, and the two ends of the telescopic double-cross shaft universal coupling 503 are fastened to the gear shaft and the reducer 502 output shaft respectively. The gear bearing seat 506 is fastened between the bracket of the rack back wheel assembly 12 and the gear rack 13 is fastened to the gear rack bottom plate 130, and the two edges of the gear rack bottom plate 130 serve as guide rail surfaces and are in contact with the rollers of the rack back wheel assembly 12.

[0114] The axial direction of the gear shaft is defined as the longitudinal direction, the radial direction of the gear and rack transmission is defined as the transverse direction, and the tangential direction of the gear and rack transmission is defined as the vertical direction. The following analyzes the six independent movements of the gear in space respectively.

[0115] 1) The deflection of the gear 504 around the transverse direction: in this direction of rotational movement, the gear 504 and the car 1 are decoupled and floating through the ball-type support 505; and the gear 504 and the gear rack 13 are limited through the contact of the meshing tooth surfaces, so that the angle position of the gear 504 in this direction of rotation follows the change of the gear rack 13, to avoid the uneven load distribution of the meshing tooth surfaces due to the angle deviation between the gear and the rack.

[0116] 2) The rotation of the gear 504 around the longitudinal direction: in this direction of rotational movement, the gear 504 and the car 1 are decoupled and floating through the ball-type support 505; the gear 504 and the car reducer 502 output shaft are linked through the telescopic double-cross shaft universal coupling 503, and there is only the mutual constraint of the rotational freedom in this direction between them, and the remaining five degrees of freedom are decoupled and floating; and the gear 504 and the gear rack 13 exist the rotational movement in this direction, to meet the demand of the gear and rack transmission;

[0117] 3) The deflection of the gear 504 around the vertical direction: in this direction of rotational movement, the gear 504 and the car 1 are decoupled and floating through the ball-type support 505; and the gear 504 and the gear rack 13 are constrained through the rack back wheel assembly 12, so that the angle position of the gear 504 in this direction of rotation follows the change of the gear rack 13, to avoid the uneven load distribution of the meshing tooth surfaces;

[0118] 4) The translation of the gear in the transverse direction: in this direction of translation, the gear 504 and the car 1 are decoupled and floating through the ball-type support 505; and the gear 504 and the gear rack 13 are constrained through the rack back wheel assembly 12, so that the translation position of the gear 504 in this direction follows the change of the gear rack 13, to ensure the correct installation distance and meshing clearance of the gear and rack transmission, and the rack back wheel assembly 12 can also offset the radial meshing force of the gear 504;

[0119] 5) Longitudinal movement of the gear 504: in this direction, the gear 504 is constrained to the car 1 through the spherical bearing 505 and does not float, and the position of the gear 504 in this direction changes with the car 1; while between the gear 504 and the rack, there is a freedom of movement in this direction, which allows a small range of movement, while the effective engagement width should not change;

[0120] 6) Vertical movement of the gear 504: in this direction, the gear 504 is connected to the car 1 through the spherical bearing 505 to transfer the vertical load and does not float; while between the gear 504 and the rack 13, there is a linear movement in this direction, which meets the requirements of the gear and rack transmission, and this linear movement and the rotational movement of the gear and rack in 2) above constitute the meshing movement together, which has a certain transmission relationship and only contains one degree of freedom.

[0121] The gear floating scheme combines the spherical bearing 505, the telescopic double-cross shaft universal coupling 503, and the rack back wheel assembly 12 to realize the adaptive floating of the gear 504 position while ensuring the effective transmission of power, i.e., the transmission of the vertical load between the car 1 and the gear bearing seat 506 and the transmission of the torque between the output shaft of the car reducer 502 and the gear shaft.

[0122] The gear floating scheme can adapt to the position deviation of the car 1 and the rack 13, reduce the influence of the position deviation on the gear and rack engagement accuracy, increase the stability and reliability of the gear and rack transmission, and help improve the transmission efficiency.

[0123] The gear floating scheme is convenient to arrange and can be used in different car 1 gear and rack arrangement forms, and can also avoid the gear shaft in a cantilever state to ensure the strength of the pinion shaft.

[0128] In the embodiment, the guide assembly 4 is arranged at eight top corners of the car 1 to enhance the guiding and tightly holding stability when parking.

[0129] In the embodiment, the guide assembly further comprises a support frame 401, the support frame 401 is in L shape, the support frame 401 is connected with the car 1, and two adjacent inner walls of the support frame 401 are respectively provided with one guide wheel set 6,

[0131] In the embodiment, the driving member is a hydraulic pushing device or an electric pushing device, the pushing device pushes the pressing plate 4021 to rise, thereby driving the guide rod and the support frame 401 to slide relative to each other, until the first inclined portion 4025 on the guide rod is matched with the second inclined portion 611 on the guide wheel set 6, in the process that the pushing device continuously pushes the pressing plate 4021 and the guide rod upwards, the second inclined portion 611 and the first inclined portion 4025 abut and slide relative to each other, under the action of the first inclined portion 4025 and the second inclined portion 611, part of the force that the pushing device pushes upwards is converted into a horizontal component force, thereby driving the guide wheels 602 to tightly hold the guide rail inwardly, wherein eight guide wheels at four corners of the car simultaneously press tightly, the guide rail is tightly held, and the car 1 is fixed; in addition, the pushing device is preferably a bidirectional pushing device, the two pressing plates 4021 can be simultaneously pushed, thereby making the two guide wheel sets 6 simultaneously tightly hold the guide rail, which is more convenient to control and is beneficial to reducing the overall weight.

[0132] In the embodiment, the guide wheel set 6 comprises a guide wheel 602, a fixed frame 601, a sliding block 604 and a pushing block 603,

[0133] The guide wheel 602 is movably arranged in the fixed frame 601, the fixed frame 601 is opened on the side away from the support frame 401 to allow the guide wheel 602 to extend outward, both ends of the guide wheel 602 are connected with a rotating shaft 606, long holes 609 are opened on the opposite sides of the fixed frame 601, the sliding block 604 is arranged between the guide wheel 602 and the fixed frame 601, the rotating shaft 606 penetrates through the sliding block 604 and extends into the long hole 609, a through hole 610 is opened on the side of the fixed frame 601 close to the support frame 401, one end of the pushing block 603 penetrates through the through hole 610 and is connected with the sliding block 604, the first elastic member 607 is connected between the pushing block 603 and the fixed frame 601, and the second inclined portion 611 is arranged on the side of the pushing block 603 close to the support frame 401.

[0134] In the embodiment, the fixed frame 601 functions to limit the movement of the guide wheel 602 and the sliding block 604, the rotating shaft 606 at both ends of the guide wheel 602 is arranged in the long hole 609 on the corresponding side of the fixed frame 601 and is in sliding fit with the long hole 609, so that the guide wheel 602 can only move along the length direction of the long hole 609 to tightly hold the guide rail, the guide wheel 602 cooperates with the surface of the guide rail in the shaft and rolls, and since the rotating shaft 606 penetrates through the sliding block 604, the movement of the sliding block 604 is also limited, the pushing block 603 adopts a T-shaped structure, one end of which penetrates through the through hole 610 on the support frame 401, after the guide rod abuts against the pushing block 603, under the limiting of the through hole 610, the pushing block 603 pushes the sliding block 604 to move in the transverse direction, thereby driving the guide wheel 602 to move inward to tightly hold; in addition, it should be noted that the first inclined portion 4025 is inclined from the upper left to the lower right, and the second inclined portion 611 is consistent with the inclination direction of the first inclined portion 4025; finally, it should be noted that the first elastic member 607 is compressed under stress during the inward movement of the pushing block 603, and the sliding block 604 is quickly reset by the elastic force of the first elastic member 607 after the tight holding is released, in addition, since the guide wheel 602 and the guide rail are in rolling fit, the first elastic member 607 can also be used for damping to enhance the stability during work.

[0135] In the embodiment, the guide wheel set 6 further comprises a limiting member 605, the limiting member 605 is slidably arranged on the upper and lower sides of the sliding block 604, and the second elastic member 608 is connected between the limiting member 605 and the fixed frame 601.

[0136] In addition to the cooperation of the rotating shaft 606 and the long hole 609 to limit the moving direction of the sliding block 604 and the guide wheel 602, the limiting piece 605 also plays a guiding and positioning role on the sliding block 604. When the second elastic piece 608 is at the free length, extrusion is generated between the limiting piece 605 and the sliding block 604, and under the action of the second elastic piece 608, the movement of the sliding block 604 in the unintended direction, such as up and down or tilting, is further limited. Under the cooperation of the second elastic piece 608 and the limiting piece 605 and the cooperation of the rotating shaft 606 and the long hole 609, it is ensured that the sliding block 604 can move stably along the direction of the long hole 609, thereby helping to tightly hold the guide rail. In addition, the second elastic piece 608 also plays a role in buffering and shock absorption, thereby enhancing the stability during movement.

[0137] In the embodiment, the two guide wheel groups 6 on the adjacent two inner walls of the support frame 401 are arranged in a staggered manner, and the two guide wheel groups 6 are perpendicular to each other, thereby avoiding interference between the two guide wheel groups 6 during the holding process.

[0139] After the technical scheme is adopted, during the movement of the sliding block 604, because the sliding block 604 adopts a wedge-shaped block, the inward movement of the sliding block 604 will continuously extrude the limiting pieces 605 on the upper and lower sides of the sliding block 604, thereby causing the second elastic piece 608 to compress and generate elastic force. Under the action of the elastic force, the limiting pieces 605 will extrude the sliding block 604, thereby helping to maintain the stability of the sliding block 604 during the sliding process. After the movement is completed, the hydraulic or electric pushing device stops continuing to rise, at this time, the positions of the sliding block 604 and the guide wheel 602 are fixed, at this time, the elastic force generated by the second elastic piece 608 will extrude the sliding block 604 through the limiting piece 605, thereby assisting in fixing the positions of the sliding block 604 and the guide wheel 602. In addition, the sliding block 604 adopts a wedge-shaped block, the shape of the limiting piece 605 is matched with the shape of the sliding block 604, and the second elastic piece 608 is set and cooperates with each other, which can make the movement of the sliding block 604 and the guide wheel 602 more stable, and the holding effect is better.

[0140] In the embodiment, two connecting plates 404 are arranged on the adjacent two sides of the fixed frame 601, and the support frame 401 is arranged between the two connecting plates 404 on the same side.

[0142] According to the technical scheme, the first guide rail 403 and the second guide rail 405 are provided with sliding grooves, and the guide rods are arranged in the sliding grooves to guide the movement of the guide rods.

[0143] In the embodiment, the guide rods include a first guide rod 4022, a second guide rod 4023, and a third guide rod 4024, the pressing plate 4021 is triangular, the first guide rod 4022, the second guide rod 4023, and the third guide rod 4024 are arranged at the three corners of the pressing plate 4021, respectively, and the support frame 401 is provided with a third guide rail 406 at the intersection of the two inner walls, and the first guide rod 4022, the second guide rod 4023, and the third guide rod 4024 are in sliding fit with the first guide rail 403, the second guide rail 405, and the third guide rail 406, respectively.

[0144] According to the technical scheme, the embodiment provides another setting for enhancing the structural strength and movement stability of the transmission member 402, that is, the pressing plate 4021 is triangular, and three guide rods and corresponding guide rails are arranged, so as to enhance the structural strength and movement stability of the entire transmission member 402.

[0147] Embodiment 9

[0148] The embodiment is different from the above-mentioned embodiments in that one side of the limiting block 9 at the back side of the car 1, which can contact the gravity block 11, is provided with a pressure trigger switch. When the gravity block 11 abuts against the limiting block 9, the pressure trigger switch triggers the jacking mechanism 82 of the locking piece 8 to work, so that the locking piece 8 locks the gravity block 11. When the roller groups are lifted to form an inclined surface that is inclined downward from the inside of the car 1 to the outside of the car 1, the gravity block 11 is located on the inclined surface and tends to move downward along the roller surface. On the one hand, the part of the third roller group 73 that is lifted on the inside of the car 1 weakens the locking of the gravity block 11 by the locking piece 8, so that the gravity block 11 tends to move outward. At the same time, the switch on the limiting block 9 is gradually released under the tendency of the gravity block 11 to move downward, and the jacking mechanism 82 of the locking piece 8 is retracted. At this time, the gravity block 11 can smoothly exit outward along the inclined surface.
