[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1-9 This invention provides a sliding mechanism for the roof of a flat warehouse: it includes a protective mechanism, a locking mechanism, and a sealing mechanism. The roof of the flat warehouse is divided into multiple cover plates 18, which are then locked to the steel structure. During the docking process of the cover plates 18, a buffer is provided to prevent collisions and damage. At the same time, the sealing process between the cover plates 18 is completed during docking, and the docking of multiple cover plates 18 is completed, further enhancing the stability between the cover plates 18.

[0032] Furthermore, the protection mechanism can quickly complete the laying and docking of the cover plate 18 on the top of the steel structure. It includes steel columns 10, on which cross beams 11 are provided. The number of steel columns 10 and cross beams 11 is multiple. Both ends of each cross beam 11 are connected to the steel columns 10. Support columns 12 are provided on the cross beams 11. The support columns 12 are arranged at the middle positions of the cross beams 11. A top beam 13 is provided on the support columns 12. Diagonal beams 14 are provided on the top beam 13. The number of diagonal beams 14 is multiple, and the multiple diagonal beams 14 are evenly distributed on the top beam 13 and the cross beams 11. First grooves 15 and second grooves 16 are provided on the diagonal beams 14. The first grooves 15 and the second grooves 16 penetrate each other. The first grooves 15 are located above the second grooves 16. Four channel steels 17 are provided inside the first grooves 15. The four channel steels 17 are evenly distributed on the diagonal beams 14. A cover plate 18 is provided on the channel steels 17. The cover plate 18 is in a "human" shape. A sliding part 19 is provided on the channel steels 17. A rolling part 20 is provided on the cover plate 18. A pulling part 21 and a buffer part 22 are provided on the rolling part 20.

[0033] Furthermore, the sliding part 19 includes a sliding plate 191 at the bottom of the channel steel 17. The sliding plate 191 is slidably connected to the bottom of the channel steel 17. The sliding plate 191 can move horizontally in the length direction of the bottom of the channel steel 17. The sliding plate 191 is located inside the second groove 16. A through hole 192 is provided at the middle position of the sliding plate 191.

[0034] Furthermore, the rolling part 20 includes a first roller 201 and a second roller 202 on the cover plate 18. Guide blocks 203 are installed on both sides of the first roller 201 and the second roller 202. An inclined surface is provided on the side wall of the guide block 203. A first through hole 204 and a second through hole 205 are provided on the channel steel 17. A first sealing block 206 is provided inside the first through hole 204. A second sealing block 207 is installed inside the second through hole 205 through a hinge.

[0035] It should be noted that, in the initial situation, both the first sealing block 206 and the second sealing block 207 are located inside the first through hole 204 and the second through hole 2'05, making the first sealing block 206 and the second sealing block 207 parallel to the bottom surface inside the channel steel 17, which is convenient for the rolling of the first roller 201 and the second roller 202.

[0036] During use, when using a crane to lift the cover plate 18 above the steel structure, in order to make the positions of the first roller 201 and the second roller 202 match those of the first through hole 204 and the second through hole 205, through the setting of the guide blocks 203, it is convenient for the first roller 201 and the second roller 202 to be inserted into the inside of the channel steel 17.

[0037] Furthermore, the channel steel 17 is inclined from left to right, with a height difference of 20cm between the leftmost and rightmost sides. The size of the first opening 204 is adapted to the size of the first roller 201, and the size of the second opening 205 is adapted to the size of the second roller 202. Moreover, the width of the first opening 204 is 2cm larger than the width of the second opening 205.

[0038] When in use, when the first roller 201 and the second roller 202 are inside the channel steel 17, under the action of gravity, the first roller 201 and the second roller 202 can roll from the left side to the right side of the channel steel 17, avoiding the need for manual pushing by the staff.

[0039] It should be noted that, since the size of the second opening 205 is smaller than the size of the first opening 204, and the size of the second roller 202 is smaller than the size of the first roller 201, the first roller 201 will not fall into the interior of the second opening 205 when it passes through the second opening 205.

[0040] It should be noted that, in the initial state, the inner bottom surface of the sliding plate 191 supports the first sealing block 206 and the second sealing block 207 respectively, thereby blocking the first roller 201 and the second roller 202 and preventing the first roller 201 and the second roller 202 from falling off during the rolling process. After the sliding plate 191 moves, the first roller 201 and the second roller 202 can fall completely into the interior of the first opening 204 and the second opening 205.

[0041] It should be noted that the bottom rightmost part of the channel steel 17 does not have a sliding plate 191, and the hinge is located to the left of the second opening 205.

[0042] When in use, when the first set of first rollers 201 and second rollers 202 are rolling inside the channel steel 17, only when they move to the far right of the channel steel 17 can the first rollers 201 and second rollers 202 directly fall into the interior of the first opening 204 and the second opening 205.

[0043] Furthermore, the pulling part 21 includes a pull rope 211 on the second sealing block 207, with one end of the pull rope 211 away from the second sealing block 207 connected to the sliding plate 191, and a guide rope block 212 installed at the bottom of the channel steel 17.

[0044] Specifically, by setting the guide rope block 212, the distance from the sliding plate 191 to one end of the guide rope block 212 can be made horizontal with the length direction of the sliding plate 191, so that the sliding plate 191 can be pulled more smoothly when the guide rope 211 moves.

[0045] In use, when the first roller 201 and the second roller 202 fall into the first opening 204 and the second opening 205 respectively, the first roller 201 squeezes the first sealing block 206, causing the first sealing block 206 to completely detach from the inside of the first opening 204. The second roller 202 squeezes the second sealing block 207, causing the second sealing block 207 to flip. When the second sealing block 207 flips, it can drive the pull rope 211, causing the pull rope 211 to drive the sliding plate 191 to slide, so that the sliding plate 191 releases its support for the subsequent first sealing block 206 and second sealing block 207, making it easier for the subsequent first roller 201 and second roller 202 to fall.

[0046] Furthermore, the buffer part 22 includes support blocks 221 on the first roller 201 and the second roller 202. There are two support blocks 221, which are located on both sides of the first roller 201. The support blocks 221 are provided with storage slots 222, and a first spring 223 is provided inside the storage slots 222.

[0047] In use, when the first roller 201 and the second roller 202 fall from the inside of the first opening 204 and the second opening 205, the first spring 223 buffers the descent of the support block 221, avoiding damage and deformation of the structure caused by the impact of the support block 221 directly contacting the channel steel 17.

[0048] Furthermore, the locking mechanism allows the cover plate 18 to lock with the channel steel 17 as it slides to the designated position. This includes an insert block 30 at one end of the cover plate 18, the number of which is the same as the number of channel steel 17. The other end of the cover plate 18 is provided with a docking groove 31 and an air cavity 32. The docking groove 31 and the air cavity 32 are interconnected, the number of which is the same as the number of which is the same as the number of which is the same as the number of which is the insert block 30. This makes the docking of the cover plate 18 more stable. The bottom of the cover plate 18 is provided with a snap-fit ​​part 33, and the inside of the air cavity 32 is provided with a locking part 34.

[0049] In use, when the first cover plate 18 slides to the far right of the channel steel 17, the first roller 201 and the second roller 202 on the cover plate 18 are completely inside the first opening 204 and the second opening 205. At the same time, driven by the second roller 202, the second sealing block 207 drives the pull rope 211 to move, and the pull rope 211 drives the sliding plate 191 to move, releasing the support of the subsequent first sealing block 206 and the second sealing block 207.

[0050] Furthermore, the snap-fit ​​part 33 includes a snap-fit ​​rod 331 at the bottom of the cover plate 18, the snap-fit ​​rod 331 is located below the mating groove 31, and the channel steel 17 has a snap-fit ​​interface 332.

[0051] In use, when the first roller 201 and the second roller 202 move the cover plate 18, the cover plate 18 moves together with the locking rod 331. During the descent of the cover plate 18, the cover plate 18 can drive the locking rod 331 to insert into the inside of the locking interface 332, thus locking the cover plate 18 with the channel steel 17.

[0052] Furthermore, the locking part 34 includes a telescopic tube 341 inside the air chamber 32. One end of the telescopic tube 341 is connected to a piston 342, which is located inside the air chamber 32. A second spring 343 is installed inside the telescopic tube 341. A slot 344 is provided on one side of the insert block 30. The size of the slot 344 is adapted to the size of the end face of the telescopic tube 341. One end of the telescopic tube 341 is an arc surface, which can cause the telescopic tube 341 to retract when the arc surface is compressed.

[0053] It should be noted that, in the initial state, the piston 342 is located in the middle of the air chamber 32. After the first cover plate 18 is installed, when the second cover plate 18 drives the first roller 201 and the second roller 202 to move inside the channel steel 17, when the second cover plate 18 moves to the position of the first cover plate 18, the bottom of the insert block 30 on the second cover plate 18 contacts one end of the telescopic tube 341. The second spring 343 can absorb the impact force of the second cover plate 18 during movement. After the impact force is removed, the second cover plate 18 continues to move forward. During this process, the second cover plate 18 drives the insert block 30 to squeeze the telescopic tube 341, and the telescopic tube 341 squeezes the piston 342 to move together. When the insert block 30 is completely inside the mating groove 31, the first roller 201 and the second roller 202 on the second cover plate 18 are just located at the first sealing block 206. On the second sealing block 207, since the first cover plate 18 unlocked the support of the sliding plate 191 for the first sealing block 206 and the second sealing block 207 during installation, the second cover plate 18 can drive the first roller 201 and the second roller 202 to fall into the interior of the first opening 204 and the second opening 205, pushing out the first sealing block 206 and the second sealing block 207. The first sealing block 206 falls out of the interior of the through opening 192, and the second sealing block 207 continues to drive the pull rope 211 to move. The pull rope 211 drives the subsequent sliding plate 191 to move, which facilitates the installation of the third cover plate 18. When the second cover plate 18 falls completely, under the action of the second spring 343, the second spring 343 drives the telescopic tube 341 to return to its original position, so that one end of the second telescopic tube 341 is inserted into the interior of the slot 344, completing the docking between the cover plate 18 and the cover plate 18.

[0054] Furthermore, the sealing mechanism performs a sealing process while the cover plates 18 are mated together, thereby increasing the waterproof performance of the cover plates 18. This includes a strip block 40 on the cover plate 18, which is in close contact with the outer surface of the cover plate 18 and is located at the edge of the cover plate 18. A first strip groove 41 is provided on the strip block 40, which is located at the bottom of the strip block 40. A sealing part 42 and an auxiliary part 43 are provided on the cover plate 18.

[0055] Furthermore, the sealing part 42 includes a first air groove 421 and a second air groove 422 on the cover plate 18. The first air groove 421 and the second air groove 422 are interconnected. A rubber tube 423 is provided on the cover plate 18. The first air groove 421 is interconnected with the air cavity 32, and the second air groove 422 is interconnected with the rubber tube 423.

[0056] It should be noted that when the telescopic tube 341 drives the piston 342 to move into the air chamber 32, the piston 342 can push the gas inside the air chamber 32 through the first air groove 421 and the second air groove 422 into the rubber tube 423, causing the rubber tube 423 to expand, making the rubber tube 423 fit more closely to the inner wall of the first strip groove 41, thus waterproofing.

[0057] Furthermore, the auxiliary part 43 includes a sealing plate 431 on the cover plate 18, the sealing plate 431 being located on the far left of the channel steel 17, the cover plate 18 being provided with bolts 432, a second strip groove 433 and an extrusion plate 434, the extrusion plate 434 being located inside the cover plate 18, and the size of the second strip groove 433 being adapted to the size of the first strip groove 41.

[0058] When in use, after the last cover plate 18 is completed, in order to ensure the overall sealing of the top of the steel structure, the workers lay the sealing plate 431 on the cover plate 18, so that the rubber tube 423 on the cover plate 18 is located inside the second strip groove 433. While the sealing plate 431 is being installed, the sealing plate 431 can drive the extrusion plate 434 to descend. During the descent of the extrusion plate 434, it can push the telescopic tube 341 to retract. The sealing plate 431 can be fixed by tightening the bolt 432.

[0059] Working principle:

[0060] When laying the cover plate 18 on the top of the steel structure, the workers control the crane to lift the cover plate 18 and control its position so that the first roller 201 and the second roller 202 on the cover plate 18 fall into the interior of the channel steel 17 simultaneously. Guided by the guide block 203, the first roller 201 and the second roller 202 are positioned in the middle of the channel steel 17. Then, under the influence of gravity and the inclined channel steel 17, the first roller 201 and the second roller 202 roll inside the channel steel 17. When the first roller 201 moves to the rightmost side of the channel steel 17, the cover plate 18 drives the insert block 30 to insert into the wall. A sealing strip is provided on the wall, located inside the first strip groove 41. The first roller 201 and the second roller 202... As the first sealing block 206 and the second sealing block 207 descend, the second roller 202 causes the second sealing block 207 to flip. The second sealing block 207 drives the pull rope 211, which in turn moves the sliding plate 191, releasing the sliding plate 191 from supporting the subsequent first sealing block 206 and the second sealing block 207. At the same time, the first roller 201 and the second roller 202 drive the support block 221 to descend, which in turn drives the first spring 223 to descend. The first spring 223 contracts to slow down the descent speed of the support block 221. Simultaneously, the cover plate 18 drives the snap-fit ​​rod 331 to insert into the inside of the snap-fit ​​interface 332 until the support block 221 contacts the bottom surface inside the channel steel 17. At this point, the first cover plate 18 is installed.

[0061] During the subsequent installation of the cover plate 18, when the cover plate 18 drives the insert 30 to contact the telescopic tube 341, the impact force of the cover plate 18 during movement is relieved by the contraction of the second spring 343. At the same time, the telescopic tube 341, while contracting, drives the piston 342 to move inside the air chamber 32. The air inside the piston 342 enters the rubber tube 423 through the first air groove 421 and the second air groove 422, causing the rubber tube 423 to expand. When the insert 30 contacts the inner wall of the mating groove 31, the first roller 201 and the second roller 202 are respectively located directly above the first sealing block 206 and the second sealing block 207. Under the action of gravity, the cover plate 18 drives the first roller 201 and the second roller 202 to drive the first sealing block 206. Simultaneously, the second sealing block 207 disengages from the inside of the first opening 204 and the second opening 205. The second sealing block 207 flips, driving the pull rope 211. The pull rope 211 drives the subsequent sliding plate 191 to move, facilitating the installation of the subsequent cover plate 18. During the descent of the cover plate 18, the insert block 30 descends together. When the insert block 30 descends to the bottom of the docking groove 31, the slot 344 and the telescopic tube 341 are at the same height. The second spring 343 returns to its original position, driving the telescopic tube 341 to return to the inside of the slot 344. At the same time, the cover plate 18 drives the strip block 40 to descend. The descending strip block 40 squeezes the rubber tube 423, causing the rubber tube 423 to enter the inside of the first strip groove 41. At this time, the cover plate 18 and the cover plate 18 are docked.

[0062] After the last cover plate 18 is installed, the leftmost side of the cover plate 18 needs to be sealed. The worker installs the sealing plate 431 on the cover plate 18. The sealing plate 431 drives the extrusion plate 434 to descend and push the telescopic tube 341 into the air chamber 32. When the sealing plate 431 contacts the cover plate 18, the rubber tube 423 is located inside the second groove 433. Tighten the bolt 432 to fix the sealing plate 431. At this time, the installation of the cover plate 18 on the entire steel structure is completed.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
