[0028] The present invention will be described in detail below with reference to the drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and the detailed implementation method and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0029] A variable-spacing storage rack for placing subway train bogies, as Figure 1 shown, includes two fixed support columns, two movable support columns 13, two fixed longitudinal beams 5 and two telescopic beams 4. One fixed longitudinal beam 5 is connected between the two fixed support columns, and another fixed longitudinal beam 5 is connected between the two movable support columns 13, and the two fixed longitudinal beams 5 are arranged in parallel,

[0030] wherein, one fixed support column is connected to one movable support column 13 through one telescopic beam 4, and the other fixed support column is connected to the other movable support column 13 through the other telescopic beam 4, and the projections of the two telescopic beams 4 on the horizontal plane do not intersect,

[0031] Both the fixed support column and the movable support column 13 are lifting columns, and rollers 12 are provided at the bottom of the movable support column 13.

[0032] As Figure 3 shown, the tops of the two fixed support columns and the two movable support columns 13 can support the bogie.

[0033] The design of the lifting support column is adopted, and the design that the horizontal position of the movable support column 3 can be adjusted, so that the dimensions in two dimensions of height and lateral span can be adjusted, and the adjustment method is simple, the operation is convenient, and the applicable range can be improved.

[0034] As Figure 2 shown, the telescopic beam 4 includes a fixed outer sleeve, a movable inner insertion tube, a handwheel 7, a transmission shaft, a bevel gear set 8, a driving lead screw 11, a driving nut 10 and at least one first bearing seat 9. One of the fixed outer sleeve and the movable inner insertion tube is fixed on the fixed support column, and the other is fixed on the movable support column 13, and the movable inner insertion tube is inserted into the fixed outer sleeve. The driving nut 10 is arranged in the movable inner insertion tube and cooperates with the driving lead screw 11 to form a lead screw-nut mechanism. The handwheel 7 is located outside the fixed outer sleeve and is connected to one end of the transmission shaft. The other end of the transmission shaft is arranged on the fixed outer sleeve through a second bearing seat, and one bevel gear of the bevel gear set 8 is sleeved on the transmission shaft, and the other bevel gear is sleeved on the driving lead screw 11. The driving lead screw 11 is arranged in the fixed outer sleeve through the first bearing seat 9.

[0035] The telescopic beam 4 adopts a fixed outer sleeve and a movable inner insertion tube, combines a lead screw-nut mechanism, and cooperates with a handwheel and a bevel gear set, so that the distance can be easily adjusted externally, improving the efficiency.

[0036] Of course, in some embodiments, one end of the transmission shaft is connected to the handwheel 7, and the other end may not adopt the fixing method of the second bearing seat, but directly open a through hole on the side wall of the fixed outer sleeve. Although this method has slightly worse effects, it is also feasible.

[0037] Particularly, in this embodiment, the fixed outer sleeve is fixed on the fixed support column, and the movable inner insertion tube is fixed on the movable support column 13. With such a design, during the process of rotating the handwheel 7, the projection position of the handwheel on the horizontal plane does not change, so that during the operation process, the operator does not need to move.

[0038] Moreover, in most embodiments, the transmission shaft is perpendicularly arranged to the driving lead screw 11, and a bevel gear set 8 with a 90-degree angle can be adopted, which has a lower cost.

[0039] Generally, the rollers 12 are universal wheels. In this way, there is no requirement for the angle between the telescopic beam 4 and the fixed longitudinal beam 5.

[0040] In this embodiment, the first bearing seat 9 includes a bearing seat mounting plate and a first bearing. The first bearing is arranged on the bearing seat mounting plate. The base surface of the bearing seat mounting plate is perpendicular to the driving lead screw 11, and the outer edge of the bearing seat mounting plate extends outside the fixed outer sleeve. Correspondingly, the telescopic beam 4 further includes a torsion-resistant baffle 14. The torsion-resistant baffle 14 is welded to the outside of the fixed outer sleeve and is arranged close to one side of the bearing seat mounting plate. The design of the torsion-resistant baffle 14 and the bearing seat mounting plate is adopted, so as to improve the load-bearing capacity of the telescopic beam and expand the applicable range.

[0041] Necessarily, the two telescopic beams 4 are arranged in parallel. In this embodiment, the telescopic beam 4 and the fixed longitudinal beam 5 are arranged perpendicular to each other. Such a design can make it easier to confirm the position of the adjustment movement and improve the operation convenience.

[0042] In this embodiment, the fixed support column includes a first fixed column 3, a first movable column 1 and a first column fixing pin 2. The first movable column 1 is inserted into the first fixed column 3 and slides along the axial direction of the first fixed column 3. After moving to the target height, it is locked and limited by the first column fixing pin 2. Specifically, positioning holes matching the first column fixing pin 2 are opened on the side walls of the first fixed column 3 and the first movable column 1.

[0043] Similarly, the movable support column 13 includes a second fixed column, a second movable column and a second column fixing pin. The second movable column is inserted into the second fixed column and slides along the axial direction of the second fixed column. After moving to the target height, it is locked and limited by the second column fixing pin. Similarly, positioning holes matching the second column fixing pin are opened on the side walls of the second fixed column and the second movable column.

[0044] In addition, in this embodiment, triangular reinforcing ribs 6 are provided between the fixed support column and the fixed longitudinal beam 5, and between the movable support column 13 and the fixed longitudinal beam 5.

[0045] According to the on-site situation, the operator can use the movable column, the column fixing pin and the fixed column to adjust the heights of the four support columns so that the heights are convenient for workers to operate. At the same time, measure the distance between the bottom planes of the bogies. Then, by simultaneously shaking the handwheels 7 on both sides, the length of the telescopic beam 4 changes through the telescopic structure in the telescopic beams 4 on both sides, so that the distance between the fixed support column and the movable support column 13 can match the bogie to be placed. Then, place the bogie on the four columns. In order to reduce the movement resistance of the telescopic structure, a pair of rollers 12 are installed under the movable support column 13. Most of the rollers 12 are hidden in the movable support column 13, which greatly reduces the movement resistance of the movable support column 13. This tooling is not only convenient for personnel to operate, but also reduces the maintenance cost of on-site equipment.
