[0001] The invention relates to the technical field of railways, and in particular to a double-layer garage. Background Art

[0002] When the EMU vehicle has finished running, it needs to be returned to the EMU maintenance base for storage and maintenance or overhaul.

[0003] The EMU maintenance base occupies a large area. Generally, there are about 10 EMU storage lines in the EMU maintenance base. With the continuous development of urban construction, the number of storage lines built previously is not enough to store more EMUs. It is necessary to plan new EMU maintenance bases or build new storage lines on the original EMU bases, resulting in a waste of land resources. At the same time, the value of land along the EMU maintenance base continues to increase. The construction of new EMU maintenance bases or new storage lines has also caused a waste of economic resources to a certain extent. Summary of the invention

[0004] The object of the present invention is to provide a double-layer garage to solve the technical problem in the prior art that the number of EMU storage lines is small and thus more EMUs cannot be stored.

[0005] As conceived above, the technical solution adopted by the present invention is:

[0006] A double-layer garage comprises a plurality of garage sections connected in sequence, wherein the garage sections comprise:

[0007] The main frame has a space capable of accommodating the EMU;

[0008] A support mechanism, comprising a support beam and a support seat, wherein the support seat can move on the support beam along the width direction of the EMU to abut against the bottom of the EMU;

[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] See also Figures 1 to 6 , an embodiment of the present invention provides a double-layer garage for storing two EMUs on one storage line in an EMU maintenance base.

[0039] The double-decker garage includes a plurality of garage sections connected in sequence, and different numbers of garage sections can be selected to be connected according to the length of the EMU 10 to adapt to different models of EMUs 10 .

[0040] The garage section includes a main frame 1, a supporting mechanism 2 and a lifting mechanism 3. The main frame 1 has a space capable of accommodating the EMU 10. The supporting mechanism 2 is used to support the bottom of the EMU 10. The lifting mechanism 3 is used to drive the supporting mechanism 2 and the EMU 10 to rise and fall. A detailed description is given below.

[0041] See also Figure 1 and Figure 2 The main frame 1 includes a plurality of slide rails 11, which extend along the height direction of the EMU 10. The plurality of slide rails 11 are spaced apart along the length direction of the EMU 10. The plurality of slide rails 11 are arranged in two rows, and a space capable of accommodating the EMU 10 is formed between the two rows of slide rails 11, thereby realizing the storage of the EMU 10.

[0042] The lifting mechanism 3 is arranged on the main frame 1. Specifically, the lifting mechanism 3 is slidably matched with the slide rail 11 to drive the support mechanism 2 and the EMU 10 to rise and fall along the slide rail 11. The multiple slide rails 11 can disperse the force, so that the slide rails 11 are not easily damaged.

[0043] The lifting mechanism 3 includes a lifting device 31 and a lifting slider 32. The lifting device 31 is fixedly connected to the main frame 1, and the lifting slider 32 is slidably connected to the slide rail 11. The lifting device 31 can drive the lifting slider 32 to move along the slide rail 11, thereby realizing the lifting function. Multiple lifting devices 31 can be arranged along the length direction of the EMU 10. Multiple lifting devices 31 move synchronously to lift the EMU 10, thereby dispersing the force on each lifting device 31.

[0044] See also Figure 3 The lifting device 31 includes an outer sleeve 311 and a lifting column 312. The outer sleeve 311 is connected to the main frame 1. The lifting column 312 is slidably arranged inside the outer sleeve 311. One end of the lifting column 312 is fixedly connected to the lifting slider 32. The outer sleeve 311 extends along the height direction of the EMU 10. Therefore, the lifting column 312 can move along the height direction of the EMU 10. It has a simple structure and occupies a small space. The lifting slider 32 is lifted and lowered on the slide rail 11 through the lifting column 312.

[0045] See also Figure 2 The support mechanism 2 includes a support beam 21 and a support seat 22. The support seat 22 can move on the support beam 21 along the width direction of the EMU 10 to abut against the bottom of the EMU 10 to support the EMU 10. The support beam 21 is connected to the lifting mechanism 3. The lifting mechanism 3 can drive the support beam 21 to rise and fall, that is, drive the support mechanism 2 and the EMU 10 to rise and fall synchronously.

[0046] Specifically, the support beam 21 is connected to the lifting slider 32. When the lifting column 312 moves along the height direction of the EMU 10, it drives the lifting slider 32 to move along the slide rail 11, and can drive the support beam 21, the support seat 22 and the EMU 10 to rise and fall on the slide rail 11, thereby realizing the lifting and lowering of the EMU 10.

[0047] The lifting slider 32 includes a first rolling track arranged along the length direction of the EMU 10 , so that the supporting mechanism 2 can roll on the lifting slider 32 .

[0048] A first roller is provided on the support beam 21, and the first roller can roll along the first track. When different positions of the EMU 10 need to be inspected, the first roller rolls on the first track, so that the support beam 21 drives the EMU 10 to move along the length direction of the EMU 10 on the lifting slider 32, thereby realizing the inspection of different positions of the EMU 10.

[0049] Specifically, the support beam 21 is a fish belly beam, which has small cross-sections at both ends, saving space and facilitating installation and disassembly, and a large cross-section in the middle. When subjected to a large force from the support mechanism 2 and the EMU 10, it will not break in the middle. The fish belly beam structure increases the bending strength and saves materials.

[0050] See also Figure 4 The support seat 22 includes a moving part 221 and a supporting part 222. The support beam 21 includes a second rolling track arranged along the width direction of the EMU 10. The moving part 221 is provided with a second roller. The second roller can roll along the second rolling track to drive the supporting part 222 to abut against the bottom of the EMU 10. When the EMU 10 enters, the moving part 221 rolls on the support beam 21 to approach the EMU 10, driving the supporting part 222 to abut against the bottom of the EMU 10 to achieve support. When the EMU 10 needs to leave, the moving part 221 rolls on the support beam 21 to move away from the EMU 10 so that the EMU 10 can drive out.

[0051] The moving part 221 includes a moving seat and a lifting rod. The second roller is arranged on the moving seat. The lifting rod can move up and down on the moving seat. The supporting part 222 is connected to the lifting rod to realize the lifting of the supporting part 222 in a small range to support the bottom of different models of EMUs 10.

[0052] The support portion 222 is rotatably connected to the lifting rod, and the support portion 222 has an extended position and a retracted position. When the EMU 10 has not entered, the support portion 222 is in the retracted position to save space to prevent interference with the entry of the EMU 10. After the EMU 10 enters, the support portion 222 rotates from the retracted position to the extended position. Driven by the moving portion 221, the support portion 222 abuts against the bottom of the EMU 10 to support the EMU 10.

[0053] See also Figure 5 and Figure 6 The garage section also includes a movable working platform 4, which is connected to the main frame 1 and can be extended and retracted along the width direction of the EMU 10. The movable working platform 4 is extended and retracted along the width direction of the EMU 10 to the position where the EMU 10 needs to be repaired, and the maintenance personnel repair the position on the movable working platform 4.

[0054] The movable working platform 4 includes a fixed layer 41 and a movable layer 42. The fixed layer 41 is fixedly connected to the main frame 1, and the movable layer 42 is slidably connected to the fixed layer 41. The structure is simple. The movable layer 42 slides on the fixed layer 41 along the width direction of the EMU 10 to realize the extension and retraction of the movable working platform 4.

[0055] See also Figure 5 The garage section also includes a ladder 5, through which maintenance personnel can go to the moving layer 42 to perform maintenance on the EMU 10. The ladder 5 has a simple structure and is easy to install.

[0056] See also Figure 2 Two rows of ground tracks 20 are provided in the space accommodating the EMU 10 . The two rows of ground tracks 20 are arranged along the length direction of the EMU 10 . The EMU 10 can travel or stop on the ground tracks 20 .

[0057] In summary, after the first EMU 10 enters the main frame 1, the support part 222 rotates from the retracted position to the extended position, and the second roller rolls on the support beam 21 to make the support part 222 close to the EMU 10, and the lifting rod is lowered to a suitable position on the moving seat, and the moving seat cooperates with the lifting rod to drive the support part 222 to abut against the bottom of the EMU 10, and the jacking column 312 rises in the outer sleeve 311, and the jacking column 312 supports the lifting slider 32 to rise on the slide rail 11, and the lifting slider 32 drives the supporting mechanism 2 and the EMU 10 to rise. When the EMU 10 is completely in the upper part of the space of the main frame 1, the lifting mechanism 3 stops rising, and the first EMU 10 is stored. At this time, the second EMU 10 can enter the interior of the main frame 1, and the second EMU 10 is located below the first EMU 10. The upper and lower parts of the main frame 1 can each store one EMU 10, realizing double-layer storage.

[0058] During the maintenance process, the first EMU 10 can move on the lifting slider 32 along the length direction of the EMU 10 to realize maintenance of different positions of the EMU 10. The maintenance personnel can also climb onto the movable working platform 4 through the ladder 5. The maintenance personnel are on the mobile layer 42, and the mobile layer 42 slides on the fixed layer 41 along the width direction of the EMU 10 to realize maintenance of different positions of the EMU 10.

[0059] After the inspection is completed, the second EMU 10 leaves the double-decker garage first, and the lifting column 312 descends to drive the lifting slider 32 to descend, thereby driving the supporting mechanism 2 and the EMU 10 to descend until the wheels of the first EMU 10 abut against the ground track 20, and then stop descending. The lifting rod moves downward to make the supporting part 222 separate from the bottom of the EMU 10, and the moving part 221 drives the supporting part 222 away from the two sides of the EMU 10. The supporting part 222 rotates from the extended position to the retracted position, and the first EMU 10 leaves the double-decker garage.
