A region in which one end of the chain 300 is connected to a deflection region 1003 and the other end is connected to a turn region 1002, and the turn region 1002 is connected to a horizontal region 1000 is defined as a horizontal deflection region 1004; in the horizontal deflection area 1004, the link plate 400, the hanging beam shaft 500 and the car carrier 600 move along the horizontal direction or the direction close to the horizontal direction, and the shape of the chain 300 is a straight line in the horizontal direction or the direction close to the horizontal direction.

In all 6 areas of the deflection type circulating stereo garage, any one area and two areas adjacent to the area are observed in isolation, and when two adjacent carrier frames 600 move in the area with a certain length of the chain plate spacing 402, the adjacent meeting exists; enumerating all combinations of the regions, and respectively determining the link plate spacing 402 when adjacent vehicle carrying frames 600 are close to meet in the combinations of the regions; when the stereo garage operates by taking the maximum value in the chain plate spacing 402 as the chain plate spacing 402, adjacent vehicle carrying frames 600 are close to meet, and the adjacent vehicle carrying frames 600 cannot collide in all motion areas; therefore, the minimum link plate spacing of the deflection type circulating stereo garage is equal to the maximum link plate spacing 402 when adjacent two carrier frames 600 meet in the combination of the areas.

The minimum gap width of two adjacent rows or two adjacent columns of vehicle carriers 600 moving in the horizontal direction or the vertical direction is called as a vehicle carrier transverse interval 601; in the turning region 1002, the hanging beam shaft 500 moves along an arc, and the radius of the arc is the sum of the length L of the chain plate and the turning radius 305 of the chain; the carriage transverse spacing 601 of the two rows of carriage frames 600 moving in the horizontal direction is designated as L2h,

the carrier transverse spacing 601 of the two rows of carrier carriers 600 moving in the vertical direction is designated as L2v,

l2v ═ 2(L + Rv) -w formula A3;

rh is the chain turning radius 305 of the turning region 1002 connected to the horizontal region 1000, and Rv is the chain turning radius 305 of the turning region 1002 connected to the vertical region 1001.

The volume of the space occupied by the outline of the motion track of the vehicle-carrying frame 600 of the circulating stereo garage is called the volume of the circulating stereo garage; under the condition of a certain size of the vehicle-carrying frame 600, the number of the vehicle-carrying frames 600 contained in the unit volume of the circulating type stereo garage marks the space utilization rate of the circulating type stereo garage; the circulating stereo garage containing the same number of the vehicle-carrying frames 600 has larger volume and lower space utilization rate.

Under the condition that the size and the number of the accommodating vehicle carrying frames 600 of the stereo garage are certain; the size of the circulating stereo garage is mainly determined by the minimum chain plate interval of the stereo garage and the transverse interval 601 of the vehicle carrying frame; the volume of the circulating stereo garage is positively correlated with the minimum chain plate distance and the transverse vehicle carrying frame distance 601 respectively; in the horizontal area 1000, the gap width between adjacent vehicle carrying frames 600 is equal to the difference between the minimum chain plate distance and the width of the vehicle carrying frame 600; in the vertical region 1001, the gap width between adjacent vehicle carrying frames 600 is equal to the difference between the minimum chain plate distance and the height of the vehicle carrying frame 600; therefore, under the condition of the same transverse spacing 601 of the vehicle carrying frames, the larger the difference between Lm and max { w, h }, the larger the wasted space of the stereo garage, and the larger the volume.

The two ends of the deflection region 1003 are respectively connected with a horizontal deflection region 1004 and a vertical deflection region 1005; two adjacent truck frames 600 respectively located in a horizontal deflection region 1004 and a vertical deflection region 1005 which are connected with the same deflection region 1003, when meeting, the distance between the top corners of the rectangular cross sections of the two truck frames 600 approaches 0; the length of the chain 300 between two adjacent load carrying frames 600 is the link plate spacing 402 of the adjacent load carrying frames 600 in the region respectively; the distance between the hanger beam axles 500 connected to the adjacent truck frames 600 is equal to the length S of the diagonal line of the truck frames 600.

In the deflection type circulating stereo garage in the prior art, the length 401 of a chain plate is kept unchanged, and a hanging beam shaft 500 always moves outside a closed curve of a chain 300; in the turning area 1002, the rotation radius and speed of the hanging beam shaft 500 and the vehicle carrier 600 are respectively larger than those of the chain 300 connected with the hanging beam shaft; in the deflection area 1003, the rotating radius and the speed of the hanging beam shafts 500 and the carrying frames 600 are respectively smaller than the rotating radius and the speed of the chains 300 connected with the hanging beam shafts, and the length of the chains 300 between the carrying frames 600, namely the chain plate spacing 402, is larger than the length of the motion trail of the hanging beam shafts 500 between the hanging beam shafts 500 connected with the adjacent carrying frames 600; therefore, when two adjacent vehicle carrying frames 600 respectively located in the horizontal deflection area 1004 and the vertical deflection area 1005 which are connected with the same deflection area 1003 are close to meet, the chain plate spacing 402 between the vehicle carrying frames 600 is the largest of the chain plate spacing 402 between the vehicle carrying frames 600 in all possible close meeting of the adjacent vehicle carrying frames 600 of the deflection type circulating stereo garage.

Therefore, the minimum link plate spacing of the prior art swing type circulation type stereo garage is equal to the link plate spacing 402 when two adjacent carrier frames 600 respectively located in the horizontal swing area 1004 and the vertical swing area 1005 which are connected to the same swing area 1003 are approximately met.

According to the discussion of "a circulating stereo garage with double-deflection function and its application mode" disclosed in chinese patent CN110259216A, when two adjacent vehicle-carrying frames 600 respectively located in a horizontal deflection region 1004 and a vertical deflection region 1005 connected to the same deflection region 1003 are close to meet, the distance 402 between the link plates between the adjacent vehicle-carrying frames 600 is greater than the length S of the diagonal line of the vehicle-carrying frame 600; the minimum chain plate spacing of the deflection type circulating stereo garage adopting the deflection device 900 with the primary deflection function is much larger than S; the minimum chain plate distance of the deflection type circulating stereo garage in the prior art is larger than the diagonal length S of the carriage frame 600, namely,

lm > S formula A4.

According to the formula A2 and the formula A3, the transverse distance 601 of the vehicle carrying frames of the deflection type circulating stereo garage is irrelevant to the structure of a deflection area 1003; because the minimum chain plate interval of the deflection type circulating stereo garage in the prior art is large, the transverse interval 601 of the vehicle carrying frame is usually designed to be small; under the condition that the size and the number of the vehicle-carrying frames 600 contained in the stereo garage are fixed, the size of the deflection type circulating stereo garage in the prior art is mainly determined by the minimum chain plate distance of the stereo garage.

The minimum chain plate spacing of the deflection type circulating stereo garage adopting the deflection device 900 with the primary deflection function in the prior art is much larger than S, and the stereo garage has larger volume under the condition of certain size and quantity of the accommodating vehicle carrying frames 600.

In a deflection area 1003 of a deflection type circulating stereo garage adopting a deflection device 900 with a double-deflection function in the prior art, the vehicle carrying frames 600 move along inclined line segments with the length and the height respectively close to the width and the height of the vehicle carrying frames 600 outside a closed curve of the chain 300, so that the deflection area 1003 additionally occupies about 1 space of the vehicle carrying frame 600, and the volume of the stereo garage is increased; since the minimum chain plate spacing of the stereo garage is greater than the diagonal length S of the vehicle-carrying frame 600 on the one hand, and the deflection area 1003 increases the volume of the stereo garage on the other hand, the deflection type circulating stereo garage using the deflection device 900 having the twice deflection function has a larger volume under the condition that the stereo garage accommodates the vehicle-carrying frame 600 in a certain size and number.

Therefore, the main disadvantage of the deflection type circulating stereo garage in the prior art is that the minimum chain plate interval is large, and under the condition of a certain size and quantity of the accommodating vehicle carrying frames 600, the stereo garage has a large volume and a low space utilization rate.

A vehicle entrance and exit is arranged in a turning area 1002 below the deflection type circulating stereo garage; as shown in fig. 1, the turning region 1002 is connected to a vertical region 1001 and a vertical deflection region 1005, respectively; when the vehicle is stored and taken out, the stereo garage moves the carriage frame 600 to the vehicle entrance and exit, and then the user stores or takes the vehicle in or out.

In a rotation area 1002 of the circulating stereo garage, the chain 300 moves along an arc around a chain rotation center 306; in a turning region 1002 connected to the horizontal region 1000, the included angle between the horizontal direction and the line connecting any point on the plane where the transmission wheel 200 is located and the chain turning center 306, or, in the turning region 1002 connected to the vertical region 1001, the included angle between the vertical direction and the line connecting any point on the plane where the transmission wheel 200 is located and the chain turning center 306, is referred to as the turning angle of the point; the rotation angle is in the range of [ -pi/2, pi/2 ].

In a turning area 1002 below the circulating stereo garage, the vehicle carrying frame 600 rotates around the driving wheel 200, and when a hanging beam shaft 500 connected with the vehicle carrying frame 600 reaches the lowest point position, the vehicle carrying frame 600 is close to the ground; when the transverse distance 601 between the vehicle carriers in the vertical area 1001 connected with the turning area 1002 is large, the turning radius of the vehicle carriers 600 is large according to the formula a3, and the adjacent vehicle carriers 600 are located in the turning area 1002 at the same time; in the turning area 1002, when two adjacent load carrying frames 600 respectively move to two sides of the turning area 1002, and the absolute values of the turning angles of two beam hanging shafts 500 connected with the load carrying frames 600 are equal, the load carrying frames 600 reach the same height, the height from the bottom of the load carrying frame 600 to the ground is called a parking height, and the included angle between the two beam hanging shafts 500 and the chain turning center 306 of the turning area 1002 is called a parking angle.

Generally, the transverse vehicle carrier spacing 601 of the vertical area 1001 connected with the turning area 1002 does not exceed the width of the vehicle carrier 600, so that the stereo garage achieves higher space utilization rate; in the deflection type circulating stereo garage in the prior art, under the condition that the transverse distance 601 between the vehicle carrying frames does not exceed the width of the vehicle carrying frames 600, the parking heights of two adjacent vehicle carrying frames 600 positioned in the rotation area 1002 are larger, only one vehicle entrance can be arranged at the central position of the rotation area 1002, and only one vehicle can be stored and taken each time; when a plurality of users simultaneously request to access the vehicle, the queuing is required to be carried out in sequence, and the waiting time is longer.

In summary, the distance between the minimum chain plates of the deflection type circulating stereo garage in the prior art is large, and under the condition that the size and the number of the accommodating vehicle-carrying frames 600 are fixed, the stereo garage is large in size and low in space utilization rate; the deflection type circulating stereo garage of the prior art using the lower turning area 1002 as the vehicle entrance and exit can only store or take out one vehicle at a time, and the waiting time for a plurality of users to request to store or take out the vehicle at the same time is long.

In the deflection type circulating stereo garage in the prior art, because the hanging beam shaft 500 always moves outside the closed curve of the chain 300, in the deflection area 1003, the rotating radius and the speed of the hanging beam shaft 500 and the vehicle carrier 600 are respectively smaller than the rotating radius and the speed of the chain 300 connected with the same; therefore, under the same link joint interval 402 and the size condition of year frame 600, the utility model discloses an in the circulating stereo garage of link joint variable length, the interval between two adjacent year frames 600 that are located the horizontal deflection region 1004 that links to each other with same deflection region 1003 and the vertical deflection region 1005 respectively is bigger than in the circulating stereo garage of deflection type of prior art, the interval between two adjacent year frames 600 that are located the horizontal deflection region 1004 that links to each other with same deflection region 1003 and the vertical deflection region 1005 respectively.

When | α | ≦ θ, the two carriage frames 600 are approaching meeting, the horizontal distance of the two carriage frames 600 is w; therefore, the temperature of the molten metal is controlled,

len1 ═ max { w × cos (β - α)/cos (α), w }, | α | ≦ θ equation 2.

When the two vehicle carrying frames 600 are close to meet each other, the vertical distance between the two vehicle carrying frames 600 is h; therefore, the temperature of the molten metal is controlled,

len1 ═ max { h × cos (β - α)/sin (| α |), h }, | α | > θ equation 3.

Since the boom axle guides 1100 of the horizontal deflection area 1004 and the vertical deflection area 1005, respectively, intersect the chain 300, the angle between the chain 300 and the boom axle guide 1100 is beta-alpha, and, therefore,

In the circulating stereo garage with the variable chain plate length, two adjacent vehicle carrying frames 600 which are respectively positioned in a rotation area 1002 and a horizontal area 1000 or a vertical area 1001 connected with the rotation area, the distance between the chain plates when meeting is close to is marked as Len 3; in the rotation area 1002, the arrangement of the chain 300 and the suspension beam shaft guide rail 1100 of the chain plate length-variable circulation type stereo garage of the present invention and the motion law of the vehicle-carrying frame 600 are basically the same as those of the deflection type circulation type stereo garage of the prior art; the link plate distance Len3 is not influenced by the deflection region 1003; therefore, the link plate spacing Len3 is substantially the same as the link plate spacing 402 when two adjacent carrier frames 600 respectively located in the turning region 1002 and the horizontal region 1000 or the vertical region 1001 connected thereto in the prior art deflection type circulation type stereo garage are close to meet, and is smaller than the minimum link plate spacing of the prior art deflection type circulation type stereo garage.

The minimum chain plate distance of the circulating stereo garage with the variable chain plate length is equal to the maximum value of the chain plate distances 402 when adjacent meeting of adjacent vehicle carrying frames 600 occurs under all combinations of motion areas; because Len, Len1, Len2 and Len3 all are less than the minimum chain plate interval of the circulating stereo garage of deflection type of prior art, consequently, the utility model discloses a circulating stereo garage of changeable link plate length's minimum chain plate interval is less than the minimum chain plate interval of the circulating stereo garage of deflection type of prior art.

The utility model discloses a when changeable circulating stereo garage of link joint length contains a plurality of regional 1003 that deflect, above-mentioned conclusion is the same to be established.

as shown in fig. 31, in the deflection region 1003, the link plate length 401 of the link plate 400 is the minimum length, and the moving speed and the turning radius of the carriage frame 600 are respectively close to the moving speed and the turning radius of the chain 300 connected thereto; in the deflecting type circulating stereo garage in the prior art, because the length 401 of the link plate 400 is larger, the rotating radius and the speed of the hanging beam shaft 500 and the vehicle carrier 600 are respectively smaller than those of the chain 300 connected with the same in the deflecting area 1003.
