[0026] According to specific embodiments of this application, such as Figures 1-8 As shown, this application provides a foldable, prefabricated railway slab storage device. The storage device includes multiple sets of storage units arranged in parallel, with multiple railway slabs placed between the multiple storage units; the storage unit includes: The main beam 5 has multiple threaded nails 7 connected to both ends of its lower part; in this embodiment, multiple threaded holes 9 are evenly distributed at both ends of the lower part of the main beam 5, and each threaded hole 9 is threadedly connected to a threaded nail 7.

[0027] Support units: Multiple support units are arranged side by side on the upper surface of the main beam 5, and a railway track slab 15 is arranged between two adjacent support units.

[0028] There are two base plates 8, each corresponding to one end of the main beam 5. The base plate 8 has multiple through holes, each through hole through which a threaded nail 7 passes, and each threaded nail 7 is threaded with a large nut 6, which is located above the base plate 8.

[0029] A lifting mechanism is provided between each base plate 8 and the main beam 5, and the distance between the base plate 8 and the main beam 5 is adjusted by the lifting mechanism.

[0030] In this storage device, at least two storage units can be placed side by side. The two ends of a railway slab 15 are respectively supported on the main beams 5 of the two storage units. At the same time, multiple railway slabs 15 can be evenly placed between two adjacent support units, so that multiple railway slabs 15 can be stored side by side on the two storage units.

[0031] Meanwhile, the threaded pegs 7 arranged at the lower part of the main beam 5 are inserted into the ground, and the threaded pegs 7 can better resist lateral force of the soil, thus improving the support stability of the storage unit and facilitating arrangement and use of the storage unit at any site.

[0032] When the height of the storage unit needs to be adjusted, the large nut 6 on the threaded peg 7 is loosened first, then the height of the lifting mechanism is adjusted, then the storage unit is pressed down, the depth of the threaded peg 7 pressed into the soil is matched with the height of the lifting mechanism, finally the large nut 6 is screwed down, and the large nut 6 is in contact with the bottom plate 8, thus further improving the support stability of the storage device.

[0033] The center of the lower part of the main beam 5 is provided with an arc-shaped groove, and the post-tensioned cable 28 is arranged in the arc-shaped groove.

[0034] In the embodiment, the arc-shaped groove is arranged at the center of the lower part of the main beam 5, which can greatly reduce the weight of the main beam 5. On this basis, the post-tensioned cable 28 is arranged in the arc-shaped groove of the main beam 5, and a prestress is applied to the main beam 5 by the post-tensioned cable 28, and the direction of the prestress is upward, so that the prestress applied to the main beam 5 by the post-tensioned cable 28 can offset a part of the pressure of the storage plate arranged on the main beam 5, thus greatly improving the load-bearing capacity of the storage device.

[0035] In the embodiment, the two ends of the post-tensioned cable 28 are respectively connected to a joint 27, and the joints 27 at the two ends of the post-tensioned cable 28 are respectively hingedly connected to the two sides of the arc-shaped groove.

[0036] The support rod assembly 29 includes a double-end screw sleeve 291 and two screw rods 292, the double-end screw sleeve 291 has two end internal thread holes 9 with opposite rotation directions, and the two screw rods 292 are respectively threadedly connected to the two end internal thread holes 9 of the double-end screw sleeve 291; the top end of one of the screw rods 292 is hingedly connected to the arc-shaped groove of the main beam 5, and the bottom end of the other screw rod 292 is hingedly connected to the post-tensioned cable 28.

[0037] In the embodiment, the support rod assembly 29 is arranged on the post-tensioned cable 28. Figure 5 For a preferred embodiment of the present application, the support rod assembly 29 is arranged on the post-tensioned cable 28. Figure 5 The details of the support rod assembly 29 are shown in the embodiment; the length of the support rod assembly 29 is adjustable, and the prestress generated by the post-tensioned cable 28 can be adjusted; specifically, when the main beam 5 in the storage device needs to be folded and placed, at this time, the main beam 5 no longer needs to bear the load, and if the post-tensioned cable 28 still applies a large prestress to the main beam 5, the main beam 5 will be deformed due to internal stress, which is not conducive to folding and placing of the main beam 5; at this time, the double-end screw sleeve 291 can be rotated to shorten the length of the support rod assembly 29, so as to reduce or even eliminate the influence of the prestress of the post-tensioned cable 28 on the main beam 5.

[0038] In other embodiments, as shown in Figure 1 , 2 , 3, 7, 8, the support rod assembly 29 can be selected as a solid support rod structure with different lengths, and the solid support rod with different lengths can be selected according to the use requirement. Although the length of the solid support rod is not adjustable, the solid support rod has good structural stability, and can ensure that the storage unit has better use stability.

[0039] When it is required to store the track plates in the storage device, the double-end screw sleeve 291 can be rotated at this time to increase the length of the support rod assembly 29, thereby increasing the prestress applied by the post-tensioned cable 28 to the main beam 5, so that the main beam 5 has greater load-bearing capacity, thereby being able to store more track plates.

[0040] In the embodiment, the plurality of screw rod 292 assemblies are parallel to each other, and the lengths of the plurality of screw rod 292 assemblies are different due to the different positions of the plurality of screw rod 292 assemblies between the post-tensioned cable 28 and the main beam 5.

The lower ends of the left lower rod 24 and the right lower rod 26 are hingedly connected to the middle part of the bottom seat 25, the upper end of the left lower rod 24 is hingedly connected to the lower part of the left nut 19, and the upper end of the right lower rod 26 is hingedly connected to the lower part of the right nut 23. The two ends of the double-end screw column 18 are respectively threadedly connected in the left nut 19 and the right nut 23, and the thread directions of the left nut 19 and the right nut 23 are opposite.

[0042] In the embodiment, the details of the lifting mechanism are shown in the attached Figure 6 When it is required to adjust the height of the lifting mechanism, the double-end screw column 18 is rotated, when the left nut 19 and the right nut 23 move towards each other, the top seat 21 and the bottom seat 25 move away from each other, at this time the lifting mechanism is raised; when the left nut 19 and the right nut 23 move away from each other, the top seat 21 and the bottom seat 25 move towards each other, at this time the lifting mechanism is lowered; in the present application, the lifting mechanism is provided and the large nut 6 is provided on the threaded peg 7, both of which simultaneously play a role in adjusting the depth of the threaded peg 7 inserted into the soil, which can play a double insurance role, and ensure the stability and safety of the height adjustment process of the storage device.

[0043] In the embodiment, the top base 21 and the bottom base 25 of the lifting mechanism can be detachably fixed in the storage device. Specifically, limiting grooves can be arranged on the lower surface of the main beam 5 and the upper surface of the bottom plate 8, the top base 21 of the lifting mechanism is located in the limiting groove on the upper surface of the main beam 5, and the bottom base 25 is located in the limiting groove on the upper surface of the bottom plate 8, so as to avoid lateral movement of the lifting mechanism during use.
