Description

Technical Field

[0001] The invention relates to the field of stereo garages, in particular to a circulating stereo garage with variable chain plate length. Background Art

[0002] The circulating stereoscopic car park includes three types: a vertical circulating stereoscopic car park as indicated by "a vertical circulating stereoscopic car park" disclosed in Chinese patent CN105672712A, a horizontal circulating stereoscopic car park as indicated by "a stereoscopic circulating double-layer parking garage" disclosed in Chinese patent CN106285109A, and a deflection-type circulating stereoscopic car park as indicated by "a circulating stereoscopic car park with double deflection function and its application method" disclosed in Chinese patent CN110259216A.

[0003] The circulating stereoscopic car park adopts the conveyor belt principle and uses two sets of transmission wheels 200. Driven by a power device 800, two sets of chains 300 connected end to end are driven to rotate in a circular manner. The transmission wheels 200 are located inside the closed curve of the chains 300. The transmission wheels 200 include sprockets, forks and wheels with smooth outer surfaces.

[0004] A triangular chain plate is provided at the corresponding position of the two pairs of chains 300, referred to as a chain plate 400 for short; the two chain plates 400 at the corresponding position are fixed or hinged to the two ends of the hanging beam shaft 500 respectively; Figure 3 As shown, the chain 300 is composed of a chain connecting plate 304, a chain link shaft 301, etc. The top of the chain plate 400 is connected to the hanging beam shaft 500, and the vertical distance from the axis of the hanging beam shaft 500 to the chain 300 is called the chain plate length 401, denoted by L.

[0005] The vehicle carrier 600 is suspended on the suspension beam shaft 500, and a vehicle is loaded on it; the vehicle carrier 600 is always kept in a horizontal direction by a vehicle carrier posture maintaining device, and moves with the suspension beam shaft 500; the appearance of the vehicle carrier 600 is approximately a cube, and the cross section of the vehicle carrier 600 is approximately a rectangle when viewed along the axis of the transmission wheel 200; the width of the rectangle is called the width of the vehicle carrier 600, recorded as w, and the height of the rectangle is called the height of the vehicle carrier 600, recorded as h, and h / w ​​is recorded as m; in the vehicle carrier 600, the vehicle is parked along the axis of the transmission wheel 200 or along the axis perpendicular to the transmission wheel 200; usually, when the vehicle is parked along the axis of the transmission wheel 200, m≧0.6; when the vehicle is parked along the axis perpendicular to the transmission wheel 200, m≧0.3; the length of the diagonal of the cross section of the vehicle carrier 600 is recorded as S, which is approximately,

[0006] S=sqrt(w^2+h^2) formula A1.

[0007] The link plates 400 are arranged at equal intervals on the chain 300; the length of the chain 300 between two adjacent carrier frames 600, that is, the length of the chain 300 between the central positions of the bottoms of two link plates 400 connected to two adjacent carrier frames 600, is called the link plate spacing 402, denoted as Len; the minimum value of the link plate spacing 402 that ensures that the carrier frames 600 do not collide during the cyclic movement is called the minimum link plate spacing of the cyclic three-dimensional garage, denoted as Lm; if the link plate spacing Len between the carrier frames 600 is set < Lm, the carrier frames 600 will collide; if Len = Lm is set, two adjacent carrier frames 600 will meet closely at certain positions, that is, the distance between certain parts of two adjacent carrier frames 600 is close to 0; if Len > Lm is set, the clearance width between two adjacent carrier frames 600 is too large, and the space occupied by the three-dimensional garage cannot be fully utilized; therefore, the cyclic three-dimensional garage body usually operates with the minimum link plate spacing, and there is close encounter of adjacent carrier frames 600 at one or some positions.

[0008] See Figure 1 to Figure 3 , the deflecting cyclic three-dimensional garage of the prior art.

[0009] A set of deflecting devices 900 are respectively arranged on the front and rear sides of the deflecting cyclic three-dimensional garage; the chain 300 rotates around the driving wheels 200 and the deflecting devices 900 to form two mutually parallel closed curves with the same shape; the number of driving wheels 200 in each set of driving wheels 200 is greater than two; the relative positions of the driving wheels 200 and the deflecting devices 900 are set such that the closed curve of the chain 300 includes at least one corner; the outer angle of the corner includes a driving wheel 200, a section of arc-shaped chain 300 and the chain 300 in a horizontal or nearly horizontal direction tangent to it; the deflecting device 900 is located at the inner angle of the corner of the closed curve of the chain 300, supporting the chain 300 and guiding the chain 300 to change direction.

[0010] In the deflecting cyclic three-dimensional garage, the moving directions of the carrier frames 600 are mainly horizontal and vertical; according to the shape of the closed curve of the chain 300, the deflecting cyclic three-dimensional garage includes shapes such as Z-shaped, C-shaped, or L-shaped.

[0011] The deflecting device 900 includes types such as the deflecting device 900 with a single deflection function and the deflecting device 900 with a double deflection function; as Figure 1 shown, the deflecting device 900 with a single deflection function includes a deflecting wheel 901; as Figure 2 shown, the deflecting device 900 with a double deflection function includes two deflecting wheels 901 or the chain guide 700 that plays the same role for the chain 300; the deflecting wheel 901 includes types such as a sprocket wheel and a wheel disc with a smooth outer peripheral surface.

[0012] As Figure 1 As shown, the deflection-type circulating stereoscopic car park includes six areas in total, namely, a horizontal area 1000 , a vertical area 1001 , a rotation area 1002 , a deflection area 1003 , a horizontal deflection area 1004 and a vertical deflection area 1005 .

[0013] The area where the chain 300 rotates around the transmission wheel 200 is defined as the rotation area 1002; in the rotation area 1002, the chain plate 400, the hanging beam shaft 500, and the vehicle carrier frame 600 rotate around the transmission wheel 200, and the outer shape of the chain 300 is an arc with a radius R, and the radius R is called the chain rotation radius 305, and the center of the arc is called the chain rotation center 306; when using a transmission wheel 200 of the type such as a sprocket and a wheel with a smooth outer surface, the chain rotation radius 305 is equal to the radius of the transmission wheel 200.

[0014] The chain 300 moves in a horizontal direction or a direction close to the horizontal direction, and the area where both ends of the chain 300 are respectively connected to the two rotation areas 1002 is defined as a horizontal area 1000; in the horizontal area 1000, the chain plate 400, the hanging beam shaft 500, and the vehicle carrier frame 600 move in a horizontal direction or a direction close to the horizontal direction, and the outer shape of the chain 300 is a straight line in the horizontal direction or a direction close to the horizontal direction.

[0015] The chain 300 moves in a direction perpendicular or nearly perpendicular to the ground, and the areas where both ends of the chain 300 are respectively connected to the two rotating areas 1002 are defined as vertical areas 1001; in the vertical area 1001, the chain plate 400, the hanging beam shaft 500, and the vehicle carrier frame 600 move in a vertical or nearly vertical direction, and the outer shape of the chain 300 is a straight line in a vertical or nearly vertical direction.

[0016] The area where the chain 300 rotates around the deflection device 900 is defined as a deflection area 1003; the deflection area 1003 is located at the inner angle of the rotation angle of the closed curve of the chain 300; in the deflection area 1003 of the deflection type circulating stereoscopic carport using the deflection device 900 with a single deflection function, the chain plate 400, the hanging beam shaft 500, and the vehicle carrier 600 experience a continuous angle change driven by the chain 300, and the outer shape of the chain 300 is an arc, the rotation radius r of the chain 300 is called the deflection radius 902, and the arc center of the chain 300 is called the deflection center; in the deflection area 1003 of the deflection type circulating stereoscopic carport using the deflection device 900 with a double deflection function, the chain plate 400, the hanging beam shaft 500, and the vehicle carrier 600 experience two angle changes driven by the chain 300, and the outer shape of the chain 300 includes two arc sections and a straight line.

[0017] One end of the chain 300 is connected to a deflection area 1003, the other end is connected to a rotation area 1002, and the area where the rotation area 1002 is connected to a horizontal area 1000 is defined as a horizontal deflection area 1004; in the horizontal deflection area 1004, the chain plate 400, the hanging beam shaft 500, and the vehicle carrier frame 600 move in a horizontal or nearly horizontal direction, and the outer shape of the chain 300 is a horizontal or nearly horizontal straight line.

[0018] One end of the chain 300 is connected to a deflection area 1003, the other end is connected to a rotation area 1002, and the rotation area 1002 is connected to a vertical area 1001, which is defined as a vertical deflection area 1005; in the vertical deflection area 1005, the chain plate 400, the hanging beam shaft 500, and the vehicle carrier frame 600 move in a vertical or inclined direction, and the outer shape of the chain 300 is a straight line in the vertical or inclined direction.

[0019] In all six areas of the deflection-type circulating stereoscopic car park, observing any one of the areas in isolation, as well as any one area and its two adjacent areas, there is a near encounter when two adjacent vehicle carriers 600 move therein with a chain plate spacing 402 of a certain length; enumerate all combinations of the above-mentioned areas, and determine the chain plate spacing 402 when adjacent vehicle carriers 600 are near encounter in the combination of the areas respectively; when the stereoscopic car park operates with the maximum value of the chain plate spacing 402 as the chain plate spacing 402, there is a near encounter of adjacent vehicle carriers 600, and adjacent vehicle carriers 600 will not collide in all movement areas; therefore, the minimum chain plate spacing of the deflection-type circulating stereoscopic car park is equal to the maximum value of the chain plate spacing 402 when two adjacent vehicle carriers 600 are near encounter in the combination of each of the areas.

[0020] The minimum gap width between two adjacent rows or columns of vehicle carriers 600 moving in the horizontal direction or vertical direction is called the vehicle carrier transverse spacing 601; in the rotation area 1002, the suspension beam shaft 500 moves along an arc, and the arc radius is the sum of the chain plate length L and the chain rotation radius 305; the vehicle carrier transverse spacing 601 of two rows of vehicle carriers 600 moving in the horizontal direction is recorded as L2h,

[0021] L2h=2(L+Rh)-hFormula A2;

[0022] The lateral distance 601 between two rows of vehicle carriers 600 moving in the vertical direction is denoted as L2v.

[0023] L2v=2(L+Rv)-wFormula A3;

[0024] Rh is the chain turning radius 305 of the turning area 1002 connected to the horizontal area 1000 , and Rv is the chain turning radius 305 of the turning area 1002 connected to the vertical area 1001 .

[0025] The volume of the space occupied by the outer contour of the movement trajectory of the vehicle carrier frame 600 of the circulating three-dimensional parking garage is called the volume of the circulating three-dimensional parking garage; under the condition of a certain size of the vehicle carrier frame 600, the number of vehicle carrier frames 600 accommodated in the circulating three-dimensional parking garage per unit volume indicates the space utilization rate of the circulating three-dimensional parking garage; for a circulating three-dimensional parking garage that accommodates the same number of vehicle carrier frames 600, the larger the volume, the lower the space utilization rate.

[0026] Under the condition that the size and number of vehicle carriers 600 accommodated in the multi-story parking garage are certain; the volume of the circulating multi-story parking garage mainly depends on the minimum chain plate spacing and the lateral spacing 601 of the vehicle carriers of the multi-story parking garage; the volume of the circulating multi-story parking garage is positively correlated with the minimum chain plate spacing and the lateral spacing 601 of the vehicle carriers, respectively; in the horizontal area 1000, the gap width between adjacent vehicle carriers 600 is equal to the difference between the minimum chain plate spacing and the width of the vehicle carrier 600; in the vertical area 1001, the gap width between adjacent vehicle carriers 600 is equal to the difference between the minimum chain plate spacing and the height of the vehicle carrier 600; therefore, under the same lateral spacing 601 of the vehicle carriers, the greater the difference between Lm and max{w, h}, the greater the wasted space of the multi-story parking garage and the larger the volume.

[0027] The two ends of the deflection area 1003 are respectively connected to a horizontal deflection area 1004 and a vertical deflection area 1005; when two adjacent vehicle carriers 600 located in the horizontal deflection area 1004 and the vertical deflection area 1005 respectively connected to the same deflection area 1003 are about to meet, the distance between the top angles of the rectangular cross-sections of the two vehicle carriers 600 approaches 0; the length of the chain 300 between two adjacent vehicle carriers 600 is the chain plate spacing 402 of the adjacent vehicle carriers 600 in the said area; the distance between the suspension beam axes 500 connected to the adjacent vehicle carriers 600 is equal to the length S of the diagonal of the vehicle carrier 600.

[0028] In the deflection type circulating stereoscopic car park of the prior art, the chain plate length 401 remains unchanged, and the hanging beam shaft 500 always moves outside the closed curve of the chain 300; in the rotation area 1002, the rotation radius and speed of the hanging beam shaft 500 and the vehicle carrier 600 are respectively greater than the rotation radius and speed of the chain 300 connected thereto; and in the deflection area 1003, the rotation radius and speed of the hanging beam shaft 500 and the vehicle carrier 600 are respectively smaller than the rotation radius and speed of the chain 300 connected thereto, and the length of the chain 300 between the vehicle carriers 600 is The degree, that is, the chain plate spacing 402, is greater than the length of the movement trajectory of the suspension beam shaft 500 between the suspension beam shafts 500 connected to adjacent vehicle carriers 600; therefore, when two adjacent vehicle carriers 600 respectively located in the horizontal deflection area 1004 and the vertical deflection area 1005 connected to the same deflection area 1003 are about to meet, the chain plate spacing 402 between the vehicle carriers 600 is the largest chain plate spacing 402 between the vehicle carriers 600 in all possible adjacent encounters of adjacent vehicle carriers 600 in the deflection-type circulating multi-story parking garage.

[0029] Therefore, the minimum chain plate spacing of the deflection-type circulating stereoscopic car park in the prior art is equal to the chain plate spacing 402 when two adjacent vehicle carriers 600 located in the horizontal deflection area 1004 and the vertical deflection area 1005 respectively connected to the same deflection area 1003 are about to meet.

[0030] According to the discussion in "A Circulating Stereoscopic Garage with Double Deflection Function and Its Application" disclosed in Chinese Patent CN110259216A, when two adjacent vehicle carriers 600 located in the horizontal deflection area 1004 and the vertical deflection area 1005 respectively connected to the same deflection area 1003 are close to each other, the chain plate spacing 402 between the adjacent vehicle carriers 600 is greater than the diagonal length S of the vehicle carriers 600; the minimum chain plate spacing of the deflection type circulating stereoscopic garage using the deflection device 900 with a single deflection function is much larger than S; the minimum chain plate spacing of the deflection type circulating stereoscopic garage in the prior art is greater than the diagonal length S of the vehicle carrier 600, that is,

[0031] Lm>S Formula A4.

[0032] According to formula A2 and formula A3, the lateral spacing 601 of the vehicle carrier frames of the deflection-type circulating stereoscopic parking garage is independent of the structure of the deflection area 1003; since the minimum chain plate spacing of the deflection-type circulating stereoscopic parking garage in the prior art is relatively large, the lateral spacing 601 of the vehicle carrier frames is usually designed to be smaller; under the condition that the size and number of vehicle carrier frames 600 accommodated in the stereoscopic parking garage are certain, the volume of the deflection-type circulating stereoscopic parking garage in the prior art is mainly determined by the minimum chain plate spacing of the stereoscopic parking garage.

[0033] The minimum chain plate spacing of the deflection type circulating stereoscopic garage using the deflection device 900 with a primary deflection function in the prior art is much larger than S. Under the condition of a certain size and number of vehicle carriers 600, the volume of the stereoscopic garage is relatively large.

[0034] In the deflection area 1003 of the deflection-type circulating stereoscopic garage using the deflection device 900 with a double deflection function in the prior art, the vehicle frame 600 moves on the outside of the closed curve of the chain 300 along an inclined line segment whose length and height are close to the width and height of the vehicle frame 600 respectively. Therefore, the deflection area 1003 additionally occupies a space of about one vehicle frame 600, increasing the volume of the stereoscopic garage. On the one hand, the minimum chain plate spacing of the stereoscopic garage is greater than the diagonal length S of the vehicle frame 600, and on the other hand, the deflection area 1003 increases the volume of the stereoscopic garage. Therefore, under the condition that the size and number of vehicle frames 600 accommodated in the stereoscopic garage are certain, the deflection-type circulating stereoscopic garage using the deflection device 900 with a double deflection function is larger in volume.

[0035] Therefore, the main disadvantage of the prior art deflection-type circulating stereoscopic garage is that its minimum chain plate spacing is large. Under the condition of a certain size and number of vehicle carriers 600, the volume of the stereoscopic garage is large and the space utilization rate is low.

[0036] The rotating area 1002 below the deflection type circulation type three-dimensional garage is provided with a vehicle entrance and exit; Figure 1 As shown, the rotation area 1002 is connected to a vertical area 1001 and a vertical deflection area 1005 respectively; when storing or retrieving a vehicle, the three-dimensional parking garage moves the vehicle carrier 600 to the vehicle entrance and exit, and then the user stores or retrieves the vehicle.

[0037] In the rotating area 1002 of the circulating multi-story parking garage, the chain 300 moves in an arc around the chain rotation center 306; in the rotating area 1002 connected to the horizontal area 1000, the angle between the line connecting any point on the plane where the transmission wheel 200 is located and the chain rotation center 306 and the horizontal direction, or, in the rotating area 1002 connected to the vertical area 1001, the angle between the line connecting any point on the plane where the transmission wheel 200 is located and the chain rotation center 306 and the vertical direction, is called the rotation angle of the point; the rotation angle is in the range of [-π / 2~π / 2].

[0038] In the rotating area 1002 below the circulating stereo garage, the vehicle frame 600 rotates around the transmission wheel 200, and when the suspension beam shaft 500 connected to the vehicle frame 600 reaches the lowest point, the vehicle frame 600 is close to the ground; when the lateral spacing 601 of the vehicle frames in the vertical area 1001 connected to the rotating area 1002 is large, according to formula A3, the rotation radius of the vehicle frame 600 is large, and there is a situation where adjacent vehicle frames 600 are located in the rotating area 1002 at the same time; in the rotating area 1002, when two adjacent vehicle frames 600 move to the two sides of the rotating area 1002 respectively, when the absolute values ​​of the rotation angles of the two suspension beam shafts 500 connected to the vehicle frame 600 are equal, the vehicle frames 600 reach the same height, and the height from the bottom of the vehicle frame 600 to the ground is called the parking height, and the angle between the two suspension beam shafts 500 and the chain rotation center 306 of the rotating area 1002 is called the parking angle.

[0039] Usually, the lateral spacing 601 of the vehicle frames in the vertical area 1001 connected to the turning area 1002 does not exceed the width of the vehicle frames 600, so that the three-dimensional parking garage can achieve a higher space utilization rate; in the prior art of the deflection-type circulating three-dimensional parking garage, when the lateral spacing 601 of the vehicle frames does not exceed the width of the vehicle frames 600, the parking height of two adjacent vehicle frames 600 located in the turning area 1002 is relatively large, and only one vehicle entrance and exit can be set in the central position of the turning area 1002, and only one vehicle can be stored and retrieved at a time; when multiple users request to store and retrieve vehicles at the same time, they need to queue up and proceed in turn, and the waiting time is relatively long.

[0040] In summary, the minimum chain plate spacing of the prior art's deflection-type circulating multi-story parking garage is relatively large. Under the condition of accommodating a certain size and number of vehicle carriers 600, the volume of the multi-story parking garage is large and the space utilization rate is low. The prior art's deflection-type circulating multi-story parking garage that uses the lower rotating area 1002 as a vehicle entrance and exit can only store or retrieve one vehicle at a time, and the waiting time is long when multiple users request to store or retrieve vehicles at the same time.

[0053] As a further technical solution, the outer shape of the suspension beam shaft guide rail in the rotation area below the stereoscopic garage is a concave curve; the outer shapes of the suspension beam shaft guide rails from the upper left end to the -63° rotation angle and from the upper right end to the 63° rotation angle in the rotation area are respectively straight lines perpendicular to the ground, and the distance from them to the chain rotation center in the rotation area is d0, and d0 is in the range of [0.54h + 0.38w to w]; the outer shape of the suspension beam shaft guide rail in the -33° to 33° rotation angle in the rotation area is a horizontal line, and the distance from it to the chain rotation center in the rotation area is d1, and d1 is in the range of [d0 - 0.4w to d0 + 0.15w]; d0, d1 and ψ0 are a set of solutions to the following formula, max{d1 - d0 / tan(ψ0 / 2), 0} ≤ 0.15w, when d1 ≥ h, ψ0 = arctan((w - d0) / d1) + arctan(d0 / (d1 - h)), when d1 < h, ψ0 = Lm / (Lm + d1 - h) * [π / 2 + arctan((w - d0) / d1)]; ψ and H1 are a set of solutions to the following formula, H1 = max{d1 - d0 / tan(ψ / 2), 0}, H1 ≤ 0.15w, ψ ≥ ψ0; the suspension beam shaft guide rail in the rotation area passes through point A in the ψ / 2 rotation angle direction and point A' in the -ψ / 2 rotation angle direction, and the height of point A and point A' from the horizontal suspension beam shaft guide rail in the rotation area is in the range of [H1 to 0.15w]; the chain rotation radius in the rotation area is R, and the chain plate spacing between the carrier frames is Len, R = Len / ψ; in the above formula, ψ is the parking angle of the carrier frame when two adjacent carrier frames are simultaneously in the rotation area, ψ0 is the parking angle of the carrier frame when there is a carrier frame in the rotation area approaching an adjacent carrier frame, H1 is the minimum value of the height of the suspension beam shaft guide rail in the ψ / 2 and -ψ / 2 rotation angle directions from the horizontal suspension beam shaft guide rail in the rotation area, w is the width of the carrier frame, h is the height of the carrier frame, h / w is in the range of [0.65 to 0.95], and Lm is the minimum chain plate spacing; the max{} is the maximum value function.

DETAILED DESCRIPTION

[0094] The following is a specific embodiment with reference to the accompanying drawings. Figure 4-Figure 35 , the technical solution of the present invention is further explained.

[0095] The invention relates to a circulating stereoscopic car park with a variable chain plate length, comprising two sets of transmission wheels 200, two pairs of chains 300, two sets of deflection devices 900, two sets of suspension beam shaft guide rails 1100, chain plates 400, suspension beam shafts 500, a vehicle carrier 600 and a set of vehicle carrier posture maintaining devices;

[0096] The axes of the transmission wheels 200 are parallel to each other, and the transmission wheels 200 are respectively arranged on both sides of the support frame 100;

[0097] The chain 300 rotates around a set of transmission wheels 200; the shape of the chain 300 is a closed curve, and the closed curve includes a corner;

[0098] At the inner angle of the corner of the closed curve of the chain 300, the deflection device 900 is respectively arranged on both sides of the support frame 100, supporting the chain 300 on the corresponding side and guiding the chain 300 to change direction;

[0099] The chain plates 400 are fixed on the two chains 300 at equal intervals.

[0100] The two ends of the suspension beam shaft 500 are respectively connected to the chain plates 400 at corresponding positions on the two pairs of chains 300;

[0101] The beam shaft guide rails 1100 are respectively arranged on both sides of the support frame 100 to support and guide the beam shaft 500; the shape of the beam shaft guide rails 1100 is a closed curve;

[0102] The vehicle carrier 600 is suspended on the suspension beam shaft 500;

[0103] The vehicle frame posture maintaining device includes a vehicle frame roller 610 provided on the vehicle frame 600 and a vehicle frame guide rail 1200 provided on the support frame 100 and guiding the vehicle frame roller 610, so that the vehicle frame 600 maintains a horizontal posture;

[0104] The chain plate 400 is composed of a chain plate fixed arm 410 and a chain plate movable arm 420; the chain plate fixed arm 410 is fixed on the chain 300; the chain plate movable arm 420 is connected to one end of the suspension beam shaft 500, and the chain plate fixed arm 410 and the chain plate movable arm 420 are telescopically connected; through the connection between the chain plate fixed arm 410 and the chain plate movable arm 420, the suspension beam shaft 500 can move along the length direction of the chain plate 400; in the deflection area 1003, the shape of the suspension beam shaft guide rail 1100 is a convex curve relative to the inner side of the chain 300 or relative to the outer side of the chain 300. The side is a concave curve, the beam shaft guide rail 1100 is located on the inner side of the closed curve of the chain 300, or the beam shaft guide rail 1100 is located on the outer side of the closed curve of the chain 300 and approximately coincides with the corresponding closed curve of the chain 300, and the beam shaft guide rail 1100 is smoothly connected to the beam shaft guide rail 1100 in the adjacent horizontal deflection area 1004 and the beam shaft guide rail 1100 in the vertical deflection area 1005; in the horizontal deflection area 1004 and the vertical deflection area 1005, the beam shaft guide rail 1100 or the chain 300 is in an inclined direction.

[0105] like Figure 7As shown, the outer shape of the beam shaft guide rail 1100 in the deflection area 1003 is a convex curve; in the rectangular coordinate system XOY with the horizontal direction as the X-axis, the coordinates of each point on the beam shaft guide rail 1100 are y=f(x), f(x) is a second-order differentiable continuous function; when the function curve is below the tangent of any point on it or on the tangent, the function curve is called a convex curve; when the function curve is above the tangent of any point on it or on the tangent, the function curve is called a concave curve.

[0106] See also Figure 4 , Figure 7 In the circulating stereoscopic car park with variable chain plate length of the present invention, the hanging beam shaft guide rail 1100 of the deflection area 1003 is located on the inner side of the closed curve of the chain 300.

[0107] In the circulating stereo garage with variable chain plate length of the present invention, two pairs of chains 300 are respectively arranged around a group of transmission wheels 200 and a deflection device 900 to form two closed curves parallel to each other; the closed curve of the chain 300 includes at least one corner; two groups of chain plates 400 are fixed on the two pairs of chains 300 in a one-to-one correspondence; the chain plates 400 at corresponding positions on the two pairs of chains 300 are respectively connected to the two ends of the hanging beam shaft 500; the two ends of the hanging beam shaft 500 move along the hanging beam shaft guide rails 1100 under the support and guidance of the two groups of hanging beam shaft guide rails 1100; the vehicle carrier 6 00 is suspended on the hanging beam shaft 500; the vehicle loaded on the vehicle carrier 600 is parked along the direction close to the axis of the transmission wheel 200 or along the direction close to the axis perpendicular to the transmission wheel 200; the power device 800 drives the transmission wheel 200 to rotate, driving the chain 300, the chain plate 400, the hanging beam shaft 500 and the vehicle carrier 600 to move; the circulating three-dimensional parking garage with variable chain plate length of the present invention includes a horizontal area 1000, a vertical area 1001, a rotation area 1002, a deflection area 1003, a horizontal deflection area 1004 and a vertical deflection area 1005, a total of 6 areas.

[0108] In the horizontal region 1000 , the vertical region 1001 and the rotation region 1002 , the beam shaft guide rail 1100 is arranged outside the closed curve of the chain 300 , and the beam shaft 500 is always located outside the closed curve of the chain 300 .

[0109] The two ends of the deflection area 1003 are respectively connected to a horizontal deflection area 1004 and a vertical deflection area 1005; in the deflection area 1003, the chain 300 has an arc shape; in the horizontal deflection area 1004, the hanging beam shaft guide rail 1100 is arranged along a horizontal or nearly horizontal direction; in the vertical deflection area 1005, the hanging beam shaft guide rail 1100 is arranged along a vertical ground or inclined direction; in the horizontal deflection area 1004 and the vertical deflection area 1005, one end of the hanging beam shaft guide rail 1100 is smoothly connected to the hanging beam shaft guide rail 1100 of the deflection area 1003, and the other end is smoothly connected to the hanging beam shaft guide rail 1100 of the adjacent rotation area 1002.

[0110] The beam shaft guide rail 1100 of the deflection area 1003 is arranged on the inner side of the closed curve of the chain 300; therefore, viewed along the axial direction of the transmission wheel 200, in the horizontal deflection area 1004 and the vertical deflection area 1005, the beam shaft guide rail 1100 intersects with the chain 300 respectively.

[0111] When the vehicle carrier 600 located in the horizontal deflection area 1004 or the vertical deflection area 1005 moves toward the deflection area 1003, the beam shaft guide rail 1100 constrains the relative positions of the chain plate movable arm 420 and the chain plate fixed arm 410 of the chain plate 400, thereby changing the chain plate length 401, and the beam shaft 500 moves within the range on both sides of the chain 300 along the length direction of the chain plate 400, and the beam shaft 500 gradually moves from the outside of the closed curve of the chain 300 to the inside of the closed curve of the chain 300.

[0112] like Figure 4 As shown, the rotation area 1002-1 is located at the outer corner of the corner of the closed curve of the chain 300; in the deflection area 1003, since the suspension beam shaft guide rail 1100 is a convex curve and is arranged on the inner side of the closed curve of the chain 300, the suspension beam shaft 500 always moves on the inner side of the closed curve of the chain 300, and the movement law of the vehicle carrier 600 is basically the same as its movement law in the rotation area 1002-1, and the movement speed and rotation radius of the vehicle carrier 600 are respectively greater than the movement speed and rotation radius of the chain 300 connected thereto.

[0113] In the deflection-type circulating multi-story parking garage of the prior art, since the hanging beam shaft 500 always moves outside the closed curve of the chain 300, in the deflection area 1003, the rotation radius and speed of the hanging beam shaft 500 and the vehicle carrier 600 are respectively smaller than the rotation radius and speed of the chain 300 connected thereto; therefore, under the same chain plate spacing 402 and the size of the vehicle carrier 600, in the circulating multi-story parking garage with variable chain plate length of the present invention, the distance between two adjacent vehicle carriers 600 located in the horizontal deflection area 1004 and the vertical deflection area 1005 connected to the same deflection area 1003 is larger than the distance between two adjacent vehicle carriers 600 located in the horizontal deflection area 1004 and the vertical deflection area 1005 connected to the same deflection area 1003 in the deflection-type circulating multi-story parking garage of the prior art.

[0114] Therefore, in the circulating multi-story parking garage with variable chain plate length of the present invention, the chain plate spacing Len of two adjacent vehicle carriers 600 respectively located in the horizontal deflection area 1004 and the vertical deflection area 1005 connected to the same deflection area 1003 when they are about to meet is smaller than the chain plate spacing 402 of two adjacent vehicle carriers 600 respectively located in the horizontal deflection area 1004 and the vertical deflection area 1005 connected to the same deflection area 1003 when they are about to meet in the deflection-type circulating multi-story parking garage of the prior art.

[0115] In the horizontal deflection region 1004 and the vertical deflection region 1005, the beam shaft guide rail 1100 is approximately a straight line, the angle between the beam shaft guide rail 1100 and the horizontal direction is denoted as α, and the angle between the chain 300 and the horizontal direction is denoted as β; -π / 2<α≦π / 2, -π / 2<β≦π / 2.

[0116] For a vehicle carrier 600 with a width of w and a height of h, let,

[0117] θ = arctan(h / w) Formula 1.

[0118] The chain plate spacing 402 of two adjacent vehicle carriers 600 that are simultaneously located in the horizontal deflection area 1004 or the vertical deflection area 1005 when they are about to meet is recorded as Len1.

[0119] When |α|≦θ, the two vehicle carriers 600 are close to each other, and the horizontal distance between the two vehicle carriers 600 is w; therefore,

[0120] Len1=max{w*cos(β-α) / cos(α),w}, |α|≦θ Formula 2.

[0121] When |α|>θ, the two vehicle carriers 600 are close to each other, and the vertical distance between the two vehicle carriers 600 is h; therefore,

[0122] Len1=max{h*cos(β-α) / sin(|α|), h}, |α|>θ Formula 3.

[0123] Since the beam guide rails 1100 of the horizontal deflection area 1004 and the vertical deflection area 1005 intersect with the chain 300 respectively, the angle between the chain 300 and the beam guide rail 1100 is |β-α|, therefore,

[0124] |β-α|>0 Formula 4.

[0125] According to Formula 2, Formula 3 and Formula 4, it can be concluded that for any value of the angle β between the chain 300 and the horizontal direction and the angle α between the beam shaft guide rail 1100 and the horizontal direction, we have:

[0126] Len1 < S Formula 5;

[0127] According to formula A4, Len1 is smaller than the minimum chain plate spacing of the deflection-type circulating stereoscopic carport in the prior art.

[0128] In the circulating stereo garage with variable chain plate length of the present invention, the chain plate spacing 402 of two adjacent vehicle frames 600 located in the horizontal area 1000 or in the vertical area 1001 when they are about to meet is recorded as Len2; in the horizontal area 1000 and the vertical area 1001, the arrangement of the chain 300, the hanging beam shaft guide rail 1100 and the movement law of the vehicle frame 600 of the circulating stereo garage with variable chain plate length of the present invention are the same as those of the deflection-type circulating stereo garage in the prior art; therefore, the chain plate spacing Len2 is equal to the width w of the vehicle frame 600 and the height h of the vehicle frame 600, respectively, which is smaller than the minimum chain plate spacing of the deflection-type circulating stereo garage in the prior art.

[0129] In the circulating stereo garage with variable chain plate length of the present invention, the chain plate spacing of two adjacent vehicle carriers 600 respectively located in the rotating area 1002 and the horizontal area 1000 or the vertical area 1001 connected thereto when they are about to meet is recorded as Len3; in the rotating area 1002, the arrangement of the chain 300, the hanging beam shaft guide rail 1100 and the movement law of the vehicle carrier 600 of the circulating stereo garage with variable chain plate length of the present invention are basically the same as those of the deflection-type circulating stereo garage in the prior art; the chain plate spacing Len3 is not affected by the deflection area 1003; therefore, the chain plate spacing Len3 is basically the same as the chain plate spacing 402 of two adjacent vehicle carriers 600 respectively located in the rotating area 1002 and the horizontal area 1000 or the vertical area 1001 connected thereto in the deflection-type circulating stereo garage in the prior art when they are about to meet, and is smaller than the minimum chain plate spacing of the deflection-type circulating stereo garage in the prior art.

[0130] The minimum chain plate spacing of the circulating stereoscopic car park with variable chain plate length of the present invention is equal to the maximum value of the chain plate spacings 402 when adjacent vehicle carriers 600 are close to each other under all combinations of the movement area; since Len, Len1, Len2, and Len3 are all smaller than the minimum chain plate spacing of the deflection-type circulating stereoscopic car park in the prior art, the minimum chain plate spacing of the circulating stereoscopic car park with variable chain plate length of the present invention is smaller than the minimum chain plate spacing of the deflection-type circulating stereoscopic car park in the prior art.

[0131] When the circulating stereoscopic carport with variable chain plate length of the present invention includes multiple deflection areas 1003, the above conclusion also holds true.

[0132] See also Figure 31-Figure 33 , the chain plate length variable circulation stereo garage of the present invention; in the deflection area 1003, the hanging beam shaft guide rail 1100 is located outside the closed curve of the chain 300, and approximately coincides with the closed curve of the chain 300 on the corresponding side;

[0133] like Fig.31 As shown, in the deflection area 1003, the chain plate length 401 of the chain plate 400 is the minimum length, and the movement speed and the rotation radius of the carrier frame 600 are respectively close to the movement speed and the rotation radius of the chain 300 connected thereto; while in the deflection-type circulating multi-story parking garage in the prior art, since the chain plate length 401 of the chain plate 400 is relatively large, in the deflection area 1003, the rotation radius and speed of the hanging beam shaft 500 and the carrier frame 600 are respectively smaller than the rotation radius and speed of the chain 300 connected thereto.

[0134] According to the same principle as above, in the circulating stereoscopic car park with variable chain plate length of the present invention, the chain plate spacing Len of two adjacent vehicle carriers 600 respectively located in the horizontal deflection area 1004 and the vertical deflection area 1005 connected to the same deflection area 1003 when they are about to meet is smaller than the chain plate spacing 402 of two adjacent vehicle carriers 600 respectively located in the horizontal deflection area 1004 and the vertical deflection area 1005 connected to the same deflection area 1003 in the deflection-type circulating stereoscopic car park in the prior art when they are about to meet; therefore, the minimum chain plate spacing of the circulating stereoscopic car park with variable chain plate length of the present invention is smaller than the minimum chain plate spacing of the deflection-type circulating stereoscopic car park in the prior art.

[0192] In the rotating area 1002, when the transmission wheel 200 is a fork wheel type and the shape of the chain guide 700 is a non-circular arc, the motion trajectory of the chain 300 in the rotating area 1002 is fitted with an arc line that is close to a semicircle; the arc line is symmetrical with respect to the straight line perpendicular to the ground passing through the chain rotation center 306, the radius of the arc line is equal to d0-L0, and the bottom of the arc line is located at the lowest point of the chain 300, and the center point O of the arc line is determined accordingly; the role played by the chain 300 in the rotating area 1002 is the same as that of the chain 300 rotating around the transmission wheel 200 with a radius of d0-L0 and an axis at point O, and formula 24 still holds.

[0193] In the rotating area 1002, the beam shaft guide rail 1100 is within a rectangle enclosed by the straight beam shaft guide rail 1100 and its extension line in the vertical direction on the left and right sides of the three-dimensional parking garage and the horizontal direction at the bottom; therefore, the minimum height of the beam shaft guide rail 1100 in the rotating angle directions of ψ / 2 and -ψ / 2 from the beam shaft guide rail 1100 in the horizontal direction of the rotating area 1002 is H1, and H1 is as shown in Formula 19.

When d1 ≥ h, when the aforesaid approaching and meeting occurs, ψ = ψ0, and ψ0 is as shown in Formula 17. When d1 < h, when the aforesaid approaching and meeting occurs and the minimum value of the length of the chain 300 between adjacent car carriers 600 is equal to the minimum chain plate spacing Lm of the three-dimensional garage, Len = Lm, ψ = ψ0, and ψ0 is as shown in Formula 18.

[0195] According to Formula 20, ψ ≥ ψ0, and adjacent two car carriers 600 located in the rotation area 1002 will not collide.

[0196] When the circulating three-dimensional garage with variable chain plate length of the present invention operates at a chain plate spacing Len, the length of the chain 300 between adjacent two car carriers 600 is Len; Len and R are set according to Formula 24, the lower limit of Len is Lm, and the upper limit of R is d1, then the parking angles of the two suspension beam shafts 500 connected to adjacent two car carriers 600 are equal to ψ; as Fig.17 shown, in the rotation area 1002, when the absolute values of the rotation angles of the suspension beam shafts 500 respectively connected to the car carrier 600-1 and the car carrier 600-2 are equal, the suspension beam shaft 500 connected to the car carrier 600-1 is located at point A in the ψ / 2 rotation angle direction, and the suspension beam shaft 500 connected to the car carrier 600-2 is located at point A' in the -ψ / 2 rotation angle direction.

[0197] Chinese Patent "Transmission System and Design Method of a Circulating Three-Dimensional Garage with Variable Chain Plate Length" with the application number 201911106050.7 points out a technical solution of a vertical circulating three-dimensional garage. When the lateral spacing 601 of the car carrier does not exceed the width of the car carrier 600, when adjacent two car carriers 600 located in the lower rotation area 1002 move to both sides of the rotation area 1002 and the absolute values of the rotation angles of the suspension beam shafts 500 connected to the adjacent car carriers 600 are equal, the height of the bottoms of the adjacent two car carriers 600 from the ground is within the range of [0 - 0.15w], and cars can be parked and retrieved simultaneously.

[0198] In the turning area 1002 below the stereoscopic car park, the technical solution of the circulating stereoscopic car park with variable chain plate length of the present invention is the same as the technical solution of the vertical circulating stereoscopic car park; therefore, the technical effects of the circulating stereoscopic car park with variable chain plate length of the present invention and the technical solution of the vertical circulating stereoscopic car park are the same; in the circulating stereoscopic car park with variable chain plate length of the present invention, under the condition that the lateral spacing 601 of the vehicle carriers in the vertical area 1001 connected to the turning area 1002 does not exceed the width of the vehicle carriers 600, the two adjacent vehicle carriers 600 located in the turning area 1002 move to the two sides of the turning area 1002 and are connected to the vehicle carriers 600. When the rotation angles of the beam shaft 500 connected to the vehicle carrier 600 are ψ / 2 and -ψ / 2 respectively, the height of the beam shaft 500 connected to the vehicle carrier 600 from the beam shaft guide rail 1100 of the rotation area 1002 below the three-dimensional parking garage is in the range of [H1 to 0.15w]; therefore, the heights of the bottoms of the two vehicle carriers 600 from the ground are in the range of [H1 to 0.15w]; according to Formulas 19 and 20, 0≦H1≦0.15w, therefore, the heights of the bottoms of the two vehicle carriers 600 respectively connected to the beam shaft 500 located at point A' and point A from the ground are in the range of [0 to 0.15w].

[0199] In the circulating stereoscopic garage with variable chain plate length of the present invention, the parking height of two adjacent vehicle carriers 600 in the rotating area 1002 is small, not more than 0.15w, and the stereoscopic garage can store and retrieve two vehicles at the same time; compared with the deflection-type circulating stereoscopic garage in the prior art, the technical solution of the circulating stereoscopic garage with variable chain plate length of the present invention shortens the waiting time when multiple users store and retrieve vehicles at the same time.

[0200] As a further embodiment, the d0 is not greater than 0.5h+0.525w.

[0201] In the circulating stereo garage with variable chain plate length of the present invention, according to the height and width of the vehicle frame 600, the distance d0 from the beam shaft guide rails 1100 on the left and right sides of the rotation area 1002 to the chain rotation center 306 of the rotation area 1002 is set in the range of [0.54h+0.38w~0.5h+0.525w]; according to formula 23, when d0 is not greater than 0.5h+0.525w, the lateral spacing L2 of the vehicle frame of the stereo garage does not exceed the width of the vehicle frame 600; and the invention with application number 20191110 The technical solution of the vertical circulating multi-story parking garage pointed out in Chinese Patent No. 6050.7 is based on the same principle. When d0 is not greater than 0.5h+0.525w, the parking height of adjacent vehicle carriers 600 is not greater than 0.15w according to the same method as above. Due to the height and width of the vehicle carriers 600, d0 is selected within the upper and lower limits of d0. When h<0.95w, the lateral spacing 601 of the vehicle carriers in the vertical area 1001 connected to the rotating area 1002 is further reduced, and the volume of the multi-story parking garage is further reduced.

[0202] As a further embodiment, the chain plate spacing 402 between the vehicle carriers 600 is not greater than 1.1 times the minimum chain plate spacing.

[0203] In the circulating multi-story garage with variable chain plate length of the present invention, the chain plate spacing Len between the vehicle carriers 600 is equal to or close to the minimum chain plate spacing Lm of the multi-story garage, and the chain turning radius R is set according to formula 24 and the parking angle ψ of two adjacent vehicle carriers 600; the multi-story garage operates at the minimum chain plate spacing Lm or close to the minimum chain plate spacing Lm, the volume of the multi-story garage is further reduced, and the space utilization rate of the multi-story garage is further improved.

[0204] As a further embodiment, the beam shaft guide rail 1100 of the rotation area 1002 is a "Π"-shaped arc-shaped continuously changing curve; the distance from the beam shaft guide rail 1100 within the rotation angle range of (34°~40°] and [-40°~-34°) of the rotation area 1002 to the chain rotation center 306 of the rotation area 1002 is 1.2 times to 1.65 times the sum of the chain plate length 401 of the horizontal area 1000 or the vertical area 1001 connected to the rotation area 1002 and the chain rotation radius 305 of the rotation area 1002; or, the distance from the beam shaft guide rail 1100 within the rotation angle range of (28°~34°] and [-34°~-28°) of the rotation area 1002 to the chain rotation center 306 of the rotation area 1002 is 1.2 times to 1.65 times the sum of the chain plate length 401 of the horizontal area 1000 or the vertical area 1001 connected to the rotation area 1002 The distance from the chain rotation center 306 of the rotation area 1002 is 1.2 to 1.6 times the sum of the chain plate length 401 of the horizontal area 1000 or the vertical area 1001 connected to the rotation area 1002 and the chain rotation radius 305 of the rotation area 1002; or, the distance from the hanging beam shaft guide rail 1100 to the chain rotation center 306 of the rotation area 1002 within the rotation angle range of [22°~28°] and [-28°~-22°] of the rotation area 1002 is 1.15 to 1.45 times the sum of the chain plate length 401 of the horizontal area 1000 or the vertical area 1001 connected to the rotation area 1002 and the chain rotation radius 305 of the rotation area 1002.

[0205] The Chinese patent application number 201911106050.7 points out a technical solution for horizontal and vertical circulating stereo garages, which adopts a variable length chain plate 400 and a "Π"-shaped arc-shaped hanging beam shaft guide rail 1100, and extends the chain plate movable arm 420 outward within a certain rotation angle range of the rotation area 1002. When the lateral spacing 601 of the vehicle carrier is small, the volume of the stereo garage accommodating the same size and number of vehicle carriers 600 is larger than the volume of the circulating stereo garage using a fixed length chain plate 400. Small; according to the discussion in the patent specification, when the lateral spacing 601 of the vehicle carriers is small, there is a close encounter between the vehicle carriers 600 in the turning area 1002 and the adjacent vehicle carriers 600 in the horizontal area 1000 or the vertical area 1001, and the lateral spacing 601 of the vehicle carriers is negatively correlated with the minimum chain plate spacing; under the same minimum chain plate spacing, the lateral spacing 601 of the vehicle carriers of the circulating three-dimensional parking garage with variable chain plate length is smaller than the lateral spacing 601 of the vehicle carriers of the circulating three-dimensional parking garage with fixed-length chain plates 400.

[0206] In the deflection-type circulating stereo garage of the prior art, the length of the chain plate 400 is fixed, and the trajectory of the hanging beam shaft 500 in the rotating area 1002 is a circular arc; the movement law of the hanging beam shaft 500 and the vehicle carrier 600 in the rotating area 1002 respectively connected to the horizontal area 1000 and the horizontal deflection area 1004 at both ends is the same as the movement law of the hanging beam shaft 500 and the vehicle carrier 600 in the rotating area 1002 of the horizontal type circulating stereo garage using a fixed length chain plate 400; the hanging beam shaft 500 and the vehicle carrier in the rotating area 1002 respectively connected to the vertical area 1001 and the vertical deflection area 1005 at both ends The movement law of 600 is respectively the same as the movement law of the hanging beam shaft 500 and the vehicle carrier 600 of the turning area 1002 of the vertical circulating stereo garage using a fixed-length chain plate 400; in the two turning areas 1002, when the lateral spacing 601 of the vehicle carrier is small, there is a close encounter between the vehicle carrier 600 in the turning area 1002 and the adjacent vehicle carrier 600 in the horizontal area 1000 or the vertical area 1001; since the lateral spacing 601 of the vehicle carrier is negatively correlated with the minimum chain plate spacing, when the minimum chain plate spacing is small, the lateral spacing L2h or L2v of the vehicle carrier of the deflection-type circulating stereo garage in the prior art is large.

[0207] The chain plate length-variable circulating stereo garage of the present invention adopts a chain plate 400 with a variable length; a rotating area 1002 connected to the horizontal area 1000 and the horizontal deflection area 1004 at both ends, or a rotating area 1002 connected to the vertical area 1001 and the vertical deflection area 1005 at both ends, adopts a "Π"-shaped arc-shaped continuous changing curve shape of the hanging beam shaft guide rail 1100; through the setting of the shape of the hanging beam shaft guide rail 1100 of the rotating area 1002, the chain plate movable arm 420 is extended outward within a certain rotation angle range of the rotating area 1002; the technical solutions of the chain plate 400 and the hanging beam shaft guide rail 1100 of the circulating stereo garage with a variable chain plate length of the present invention are respectively the same as those of the patent application number 2019 The technical solutions of the horizontal circulating stereoscopic car park or the vertical circulating stereoscopic car park indicated in Chinese Patent No. 11106050.7 are the same; therefore, in the turning area 1002, the circulating stereoscopic car park with variable chain plate length of the present invention has the same technical effect as the technical solution of the horizontal or vertical circulating stereoscopic car park; the circulating stereoscopic car park with variable chain plate length of the present invention, through the above-mentioned arrangement of the hanging beam shaft guide 1100 and the chain plate 400 in the turning area 1002, reduces the lateral spacing L2h or L2v of the vehicle carrier frame under the conditions of the same size of vehicle carrier frame 600 and the same minimum chain plate spacing, thereby further reducing the volume of the stereoscopic car park and improving the space utilization rate of the stereoscopic car park under the condition of accommodating the same number of vehicle carrier frames 600.
