[0050] In the first aspect, the present invention provides a structure for initial connection of the throat area of ​​a vehicle base, which is arranged in a warehouse 1, and includes a plurality of warehouse initial tracks arranged in parallel with each other, and an entry line 4 and an exit line 5 arranged in parallel with each other. Among them, the plurality of warehouse initial tracks are located in the middle of the warehouse 1 and form a warehouse initial track set 2, a level crossing 7 is arranged between the warehouse initial track set 2 and the entry line 4 and the exit line 5, the warehouse initial track set 2 is connected with the entry line 4 and the exit line 5 to form a warehouse initial track throat area 6, and the warehouse initial track throat area 6 partially overlaps with the level crossing 7.

[0051] As an optional implementation, in some embodiments, the warehouse initial track set includes an upper half initial track set 8 and a lower half initial track set 9.

[0052] As an optional implementation, in some embodiments, several other warehouse tracks are also included, and the several other warehouse tracks are parallel to the several initial warehouse tracks, and the several other tracks form a set 3 of other warehouse tracks.

[0053] Specifically, Figure 1 As shown, in order to shorten the length of the throat area as much as possible, the arrangement is compact, and it can be used as a connection type suitable for the initial track of the throat area of ​​most current vehicle bases. In this embodiment, the structure of the initial connection of the throat area of ​​the vehicle base of the present invention is set in the warehouse 1, and the throat area corresponding to the warehouse 1 is provided with an exit line 5 and an entry line 4, and the exit line 5 and the entry line 4 are arranged in parallel. The tracks in the warehouse are divided into the warehouse initial track set M1 and the warehouse other track set M2. The present invention only implements the track connection in the warehouse initial track set M1, and the tracks in the warehouse other track set M2 will be connected in the form of a combined turnout, which is not explained in the present invention.

[0054] In a second aspect, the present invention provides a method for arranging the initial connection of the throat area of ​​a vehicle base. Based on the structure of the initial connection of the throat area of ​​the vehicle base mentioned above, the method comprises the following steps: constructing an initial track set of the warehouse in the warehouse, and setting an entry line and an exit line; partitioning the initial track set of the warehouse to obtain an upper half initial track set and a lower half initial track set; connecting an initial track in the upper half initial track set and an initial track in the lower half initial track set to the entry line and the exit line respectively, and forming a turnout on the connecting line; calculating the deflection angle of the turnout, and connecting the remaining initial tracks to the entry line and the exit line according to the calculation result.

[0055] As an optional implementation, in some embodiments, the step of calculating the deflection angle of the turnout also includes: determining the main track and the side track in the formed turnout, and calculating the deflection angle of the main track and the deflection angle of the side track respectively according to the angle of the turnout and the angle multiple of the initial track of the warehouse and the entrance and exit line.

[0056] As an optional implementation, in certain embodiments, the step before determining the main track and the side track in the formed turnout also includes: judging whether the entry line and the exit line and the initial track of the initial track set of the warehouse are in the same line span as the connected initial track set of the warehouse, based on whether there are fallen columns between the entry line and the exit line and the initial track of the warehouse initial track set; if there are fallen columns, they are different line spans; if there are no fallen columns, they are the same line span.

[0057] As an optional implementation, in some embodiments, the step after determining whether the entry line and the exit line are in the same span with the initial track of the connected warehouse initial track set also includes: adjusting the number of connections between the initial track and the entry and exit lines in the upper half initial track set and the lower half initial track set according to the determination result and combining the angle between the warehouse initial track and the entry and exit line; if the determination result is the same span, and the angle between the warehouse initial track and the entry and exit line is between 0 and 5 times the angle, then the upper half initial track set The number of connections between the initial track set in the combined and lower half areas and the entry and exit lines is 3; if the judgment result is different line spans, and the angle between the initial track in the warehouse and the entry and exit lines is between 0 and 2 times the angle, the number of connections between the initial track set in the upper half area and the initial track set in the lower half area and the entry and exit lines is 4; if the judgment result is different line spans, and the angle between the initial track in the warehouse and the entry and exit lines is between 3 and 5 times the angle, the number of connections between the initial track set in the upper half area and the entry and exit lines is 4, and the number of connections between the initial track set in the lower half area and the entry and exit lines is 2.

[0058] Specifically, in order to achieve balanced adjustment according to the bifurcation conditions and the number of connections between the entry and exit section lines and the initial tracks of the warehouse, the layout method of the present invention is understood through the following embodiments.

[0059] The warehouse tracks are divided into the lower half initial track set m1 and the upper half initial track set m2, as shown in Figure 2 As shown, the exit line is responsible for the initial track set m1 in the lower half, and the entry line is responsible for the initial track set m2 in the upper half.

[0060] Match the initial track sets m1 and m2 in the upper and lower half of the warehouse. One end of the exit line and the entry line forms a certain angle β with the parallel direction of the warehouse, where β=n*α, n∈{0,1,2,3,4,5}, α is the turnout angle, and n is the multiple angle, such as Figure 3As shown. In addition, due to the different angles between the warehouse and the entry and exit lines, and the initial tracks connected by the exit and entry lines are in the same span or different spans. Specifically, when the entry and exit lines and the connected initial tracks are in the same span, and when the angle between the entry and exit lines and the warehouse tracks is between 0 and 5 times the angle, the number of initial connected tracks in the upper and lower halves of the warehouse is 3. When the entry and exit lines and the connected initial tracks are in different spans, and the angle between the entry and exit lines and the warehouse tracks is between 0 and 2 times the angle, the number of initial connected tracks in the upper and lower halves of the warehouse is 4; when the angle between the entry and exit lines and the warehouse tracks is between 3 and 5 times the angle, the number of initial connected tracks in the upper half of the warehouse is still 4, and the number of initial connected tracks in the lower half is 2.

[0061] Therefore, the number of tracks contained in the initial track sets m1 and m2 of the upper and lower halves of the matching warehouse is different, as shown in the following example: Figure 4a , Figure 4b , Figure 4c shown.

[0062] The initial track of the warehouse is initially connected to the exit line and the entry line. When n = 0, that is, the warehouse is parallel to the exit line and the entry line, the line spacing value of the initial track L1 to be connected and the initial track L1' to be connected is different from the line spacing value of the exit line and the entry line. Therefore, the exit line is connected to the initial track L1 in a straight line, and the entry line needs to be connected to the initial track L1' in the form of two reverse circular curves, such as Figure 5 When n∈{1, 2, 3, 4, 5}, that is, the warehouse and the exit and entry lines present an angle β, the throat curve endpoint does not enter the level crossing as a principle, the initial track L1, L1' and the intersection of the outer edge of the level crossing are used as reference points, and are connected to the entry and exit lines through a circular curve with a curve radius R, as shown in Figure 6 As shown in FIG. 1 , since the initial tracks L1 and L1' have completed the connection action, the subsequent steps only need to consider the remaining track connections of the initial track sets m1 and m2.

[0063] Connect the remaining tracks in the initial track set of the warehouse. Determine the angle of the main track of the turnout and deduce the angle of the side track to complete the calculation of all the initial track angles in the throat area; based on the principle that the endpoint of the curve in the throat area does not enter the level crossing, determine the intersection of the initial track of the warehouse and the outer edge of the level crossing as the reference point. The endpoint of one end of the curve connecting the initial track of the warehouse and the turnout overlaps with the reference point. According to this principle, the tangent length formula and trigonometric function calculation formula are used to calculate and determine the position coordinates of the main track and side track of the turnout. The tangent length T formula in this step is:

[0064] T = tan(γ / 2)*R;

[0065] Where: R is the curve radius; γ is the deviation angle between the turnout and the initial track of the warehouse.

[0066] And when γ=0, the tangent length T=0, at which time the turnout track is connected to the warehouse track in a straight line.

[0067] After determining the angle and position coordinates of the main track and side track of the turnout, the initial track in the warehouse and the turnout track are connected through the turnout and warehouse guide curve.

[0068] Embodiment 1: Figure 7 and Figure 8 As shown, the initial tracks L1 and L1' of the warehouse are the same line span. The set of the initial tracks of the remaining warehouses included in the upper half is m1 = {L2', L3'}, and the set of the initial tracks of the remaining warehouses included in the lower half is m2 = {L2, L3}.

[0069] The calculation formula for the initial track angle of the upper warehouse is:

[0070] γ1=(n+1)*α, γ2=n*α, applicable to n∈{0, 1, 2, 3, 4, 5}.

[0071] The calculation formula for the initial track angle of the lower half warehouse is:

[0072] γ1=(n-1)*α, γ2=n*α, applicable to n∈{0, 1};

[0073] γ1=(n-1)*α, γ2=(n-2)*α, applicable to n∈{2, 3, 4, 5}.

[0074] Where: γ1 is the main track deviation angle of the turnout, γ2 is the side track deviation angle of the turnout, α is the turnout angle, and n is the multiple of the angle.

[0075] The track connection action of the upper half of the warehouse initial track. The main track deviation angle of the turnout generated by the warehouse initial track L3' and the entry line is γ1. Through the above calculation method, the position of the turnout is located, and the circular curve is connected to the warehouse initial track L3'. The warehouse initial tracks L2' and L3' are the same line span, and the main track connected to L3' generates a left-opening turnout. At this time, the side track of the turnout has a deviation angle of γ2 with the warehouse initial track L2', and is connected to the warehouse initial track L2' through a circular curve. The above warehouse initial track connection sequence is L3'-L2', and the track connection in the upper half of the warehouse initial track is completed.

[0076] Track connection action in the lower half of the warehouse initial track. When the angle multiple of the entry and exit line and the warehouse initial track is n∈{0,1}, the track connection sequence in the lower half of the warehouse initial track is mirrored to the track connection sequence in the upper half of the warehouse initial track, and the warehouse initial track connection sequence is L3-L2, such as Figure 7As shown. When the angle multiple number n∈{2, 3, 4, 5} between the entry and exit line and the initial track of the warehouse, the main track deviation angle of the turnout generated by the initial track L2 of the warehouse and the exit line is γ1. Through the above calculation method, the position of the turnout is located, and the circular curve is connected to the initial track L2 of the warehouse. The initial tracks L2 and L3 of the warehouse are the same line span, and the main track connected to L2 generates a left-opening turnout. At this time, the side track of the turnout has a deviation angle of γ2 with the initial track L3 of the warehouse, and is connected to the initial track L3 of the warehouse through a circular curve. The above-mentioned initial track connection sequence of the warehouse is L2-L3, and the track connection in the lower half of the initial track of the warehouse is completed.

[0077] Embodiment 2: Fig. 9 and Fig.10 As shown, the initial tracks L1 and L1' are different line spans. The remaining initial track set contained in the upper half is m1 = {L2', L3', L4'}; when the angle multiple n∈{0, 1, 2}, the remaining initial track set contained in the lower half is m2 = {L2, L3, L4}, and when the angle multiple n∈{3, 4, 5}, the remaining initial track set contained in the lower half is m2 = {L2}.

[0078] The calculation formula for the initial track angle of the upper warehouse is:

[0079] γ1=(n+1)*α, γ2=(n+2)*α, applicable to n∈{0, 1, 2, 3, 4, 5}.

[0080] The calculation formula for the initial track angle of the lower half warehouse is:

[0081] γ1=(n-1)*α, applicable to n∈{0,1,2,3,4,5}, γ2=(n-2)*α, applicable to n∈{0,1,2};

[0082] γ1 is the main track deviation angle of the turnout, γ2 is the side track deviation angle of the turnout, α is the turnout angle, and n is the multiple of the angle.

[0083] Track connection action in the upper half of the warehouse initial track. The main track deviation angle of the turnout generated by the warehouse initial track L2' and the entry line is γ1. Through the above calculation method, the position of the turnout is located, and the circular curve is connected to the initial track L2'. Similarly, the warehouse initial track L3' is connected. The warehouse initial tracks L4' and L3' are the same line span, and the main track connected to L3' generates a right-opening turnout. At this time, the side track of the turnout has a deviation angle of γ2 with the warehouse initial track L3', and is connected to the warehouse initial track L4' through a circular curve. The above warehouse initial track connection sequence is L2'-L3'-L4', and the track connection in the upper half of the warehouse initial track is completed.

[0084] Track connection action in the lower half of the warehouse initial track. When the angle multiple of the entry and exit line and the warehouse track is n∈{0, 1, 2}, the track connection sequence in the lower half of the warehouse initial track is mirrored to the track connection sequence in the upper half of the warehouse initial track. The initial track connection sequence is L2-L3-L4, such as Fig. 9 When the angle multiple of the entry and exit line and the initial track of the warehouse is n∈{3, 4, 5}, the main track deviation angle of the turnout generated by the initial track L2 of the warehouse and the exit line is γ1. Through the above calculation method, the position of the turnout is located, and the circular curve is connected to the initial track L2, as shown in Fig.10 As shown in the figure, the track connection of the lower half of the initial track in the warehouse is completed.
