[0001] The utility model relates to the field of rail transit, in particular to a track slab for subways. Background Art

[0002] A subway is a rapid, high-capacity, and electrically powered rail transit built in cities, running on a fully enclosed line, including underground and above-ground sections.

[0003] During the construction of subways, track slabs are usually required. According to a track slab for subways disclosed in the patent publication number CN213653051U, this device effectively overcomes the problems that in the traditional fastener track system during use, due to the vibration of the train, the fasteners become loose; and in order to ensure the safety of train operation, the fasteners need to be frequently inspected and re-tightened, resulting in a large amount of maintenance work and high maintenance costs. However, when installing the rail body, this device adopts a direct embedding installation method. Since there is generally a expansion joint reserved between adjacent track segments, the rail body is relatively unstable during subsequent use. Although there are still devices such as fasteners to fix the rail, it may still shake or slip in the traveling direction, posing a certain safety hazard.

[0004] Therefore, a brand-new track slab for subways is proposed to solve the above technical problems. Content of the Utility Model

[0005] The technical problem solved by the utility model lies in that in the prior art, the rail is installed in the rail groove by a direct embedding method. Due to the influence of the expansion joint, it shakes or slips in the traveling direction, posing a certain safety hazard.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems to be solved, the technical features constituting the technical solutions, and the technical effects brought.

[0027] As Figures 1 to 4 shown, a track slab for a subway includes a U-shaped plate body 1, and a plurality of asphalt pouring grooves 3 are provided on the middle surface of the plate body 1; two rail grooves 4 are provided on the upper parts on both sides of the plate body 1, and two groups of rails 5 are respectively embedded in the two rail grooves 4; the rail groove 4 is an inverted T shape; further included are:

[0028] An installation plate 6 is arranged below the rail 5, is matched with the shape of the rail groove 4, and a first card slot 601 is provided on the side surface.

[0029] An installation groove 501 is arranged on the side wall of the plate body 1.

[0030] A sliding rod 502 is arranged in the installation groove 501 along the traveling direction of the rail 5.

[0031] A sliding block 503 is slidably arranged on the sliding rod 502.

[0032] A pull rod 504 is horizontally arranged, a vertical pulling head is provided at one end, a first spring 505 is arranged between the vertical pulling head and the sliding block 503, and the other end penetrates through the sliding block 503 and the side wall of the installation groove 501 and then extends into the first card slot 601.

[0033] In the device of the present invention, the main working process is as follows: After the track slab is installed at a predetermined installation position and fixed, the rail 5 is embedded in the rail groove 4. By sliding the sliding block 503 on the sliding rod 502, one end of the pull rod 504 is aligned with the through hole on the side wall of the installation groove 501, so as to press against the side wall of the installation plate 6 below the rail 5, and the position of the rail 5 is adjusted by moving it back and forth, so that the first card slot 601 on the side surface of the installation plate 6 is aligned with the pull rod 504. The pull rod 504 is pushed into the first card slot 601 under the action of the first spring 505, so as to maintain the locking of the rail 5. At the same time, the rail groove 4 is an inverted T shape, which can be well adapted to the installation plate 6, so as to limit the position of the rail 5 in the vertical direction and avoid vibration of the rail 5.

[0034] As a preferred embodiment, a second card slot 506 is further provided on the side wall of the installation groove 501.

[0035] In this embodiment, a second card slot 506 is further provided on the side wall of the installation groove 501, so as to fix the horizontal position of the pull rod 504 on the sliding rod 502 through the second card slot 506 during the transportation of the track slab, ensuring that the pull rod 504 will not accidentally extend out of the through holes of the sliding block 503 and the side wall of the installation groove 501 due to vibration during the transportation of the track slab, and avoiding damage to the pull rod 504.

[0036] As a preferred embodiment, it further includes a blockage prevention block 7 inserted into the asphalt pouring groove 3.

[0037] In this embodiment, by arranging the blockage prevention block 7 in the asphalt pouring groove 3, external flying stones or other sundries are prevented from falling into the asphalt pouring groove 3, resulting in blockage of the asphalt pouring groove 3, so as to facilitate the subsequent asphalt pouring process.

[0038] As a further embodiment, a limit block 701 with a size larger than that of the asphalt pouring groove 3 is provided on the top of the blockage prevention block 7.

[0039] In this embodiment, by arranging the limit block 701 on the top of the blockage prevention block 7, the whole blockage prevention block 7 is prevented from falling into the asphalt pouring groove 3, and it is also convenient to quickly pull out the blockage prevention block 7 when asphalt pouring is required.

[0040] As a further embodiment, a horizontal slot 702 is provided on the side wall of the blockage prevention block 7, a block 703 with one end extending out of the slot 702 is arranged in the slot 702, and the block 703 is connected to the end wall of the slot 702 through a second spring 704; a third card slot 705 matching the block 703 is provided on the side wall of the asphalt pouring groove 3.

[0041] In this embodiment, a structure for locking the position of the blockage prevention block 7 is provided. Specifically, when the block 703 in the slot 702 is blocked by the inner wall of the asphalt pouring groove 3 when the blockage prevention block 7 is inserted into the asphalt pouring groove 3, the second spring 704 is compressed, and the blockage prevention block 7 can move smoothly. When the blockage prevention block 7 falls into the appropriate position, rotate the blockage prevention block 7 so that the slot 702 is aligned with the third card slot 705, and the block 703 pops out of the slot 702 under the action of the second spring 704, so as to be embedded in the card slot 705 and abutted tightly, realizing the fixation of the blockage prevention block 7 and avoiding accidental detachment of the blockage prevention block 7 due to external vibration during transportation or construction.

[0042] As a further embodiment, there are three groups of the slots 702, the clamping blocks 703 and the second springs 704, which are evenly distributed on the outer wall of the square block; there are also three third clamping slots 705, which correspond to the clamping blocks 703 one by one.

[0043] In this embodiment, the number of the anti-blocking blocks 7 is three, and they are evenly distributed on the outer wall of the square block. Similarly, there are three third clamping slots 705, which are evenly distributed on the inner wall of the asphalt pouring groove 3, so as to correspond to the clamping blocks 703 one by one. Through the three groups of clamping structures, a more stable fixation of the anti-blocking blocks 7 is realized.

[0044] As a preferred embodiment, a pressure dividing plate 602 is further provided at the upper end of the mounting plate 6, and the lower surface of the pressure dividing plate 602 is flush with the upper surface of the rail groove 4; the rail 5 is arranged on the pressure dividing plate 602.

[0045] In this embodiment, the function of the pressure dividing plate 602 is on the one hand to assist the lower mounting plate 6 to bear the upper load, and on the other hand to assist the mounting plate 6 to prevent the rail 4 from vibrating on the rail groove 5.
