[0023] like Figure 1As shown, the track slab prefabrication device includes a base 3, on which a casting seat 4 is mounted. A standard side mold 6 is hinged to the front side of the casting seat 4, and an extra-high side mold 5 is hinged to the rear side of the casting seat 4. A left extra-high side mold 85 is installed on the left side of the casting seat 4, and a right extra-high side mold 95 is installed on the right side of the casting seat 4. The extra-high side mold 5, the left extra-high side mold 85, the standard side mold 6, the right extra-high side mold 95, and the casting seat 4 form a casting cavity 15 with an open top. Several sleeper platform mold basins 10 are installed at intervals on the top of the casting seat 4, and several support legs 1 are installed at the bottom of the base 3. A connection is installed between the support legs 1 and the base 3. Wedge plate 2, and base 3 is inclined under the action of wedge plate 2. In this embodiment, base 3, casting seat 4, extra-high side mold 5, left extra-high side mold 85, standard side mold 6, and right extra-high side mold 95 are all steel parts. The cross-section of casting seat 4 is a rectangular frame with an open bottom, while the cross-section of base 3 is a rectangular structure. Base 3 and casting seat 4 can be connected by welding. Alternatively, a flash can be provided at the bottom of casting seat 4. Then, base 3 and casting seat 4 can be detachably connected by bolts. During the prefabrication of track slab, a suitable wedge plate 2 is selected and installed between base 3 and support leg 1, such as... Figure 2 As shown, after the wedge plate 2 is installed, the base 3 will be tilted, resulting in the rear bottom and front side of the base 3 being higher. Therefore, the support legs 1 will be selected with different heights as needed to adapt to the tilted setting of the base 3. After the base 3 is tilted, the casting seat 4 will also tilt, and the bottom of the casting cavity 15 will also tilt. After the casting is completed, the bottom of the casting cavity 15 will form a slope. When pouring concrete, the surface of the concrete will be smoothed. Therefore, after the track slab is poured, when the plane of the track slab is placed on a horizontal plane, the side with the sleeper platform is tilted, thus realizing the prefabrication of the tilted track slab. Figure 3 As shown, after the wedge plate 2 is disassembled, the rectangular track plate can be prefabricated.

[0024] In this embodiment, as Figure 2 As shown, multiple hinged ear plates 7 are spaced apart on the front and rear side walls of the casting base 4. The ultra-high side mold 5 and the standard side mold 6 are hinged to the corresponding hinged ear plates 7. Furthermore, the top and bottom of the ultra-high side mold 5 are provided with rearward-extending plates, and its left and right ends are also welded through the plates. A hinge plate is provided on the plate at the bottom of the ultra-high side mold 5. The hinge plate and the hinged ear plate 7 are connected by a hinge shaft. Similarly, the standard side mold 6 is installed in the same way as the ultra-high side mold 5. Furthermore, the left ultra-high side mold 5 and the right ultra-high side mold 5 can also be hinged to the casting base 4, and their installation method is the same as that of the ultra-high side mold 5 and the casting base 4.

[0025] In this embodiment, the super-high side mold 5 is installed with the left super-high side mold 85 and the right super-high side mold 95 by a locking assembly (not shown in the figure). The standard side mold 6 is also installed with the left super-high side mold 85 and the right super-high side mold 95 by a locking assembly. The locking assembly is existing technology and can be referred to as the locking between the panels of a truck body.

[0026] In this embodiment, as Figure 1 As shown, the sleeper platform mold 10 has a positioning protrusion 14, and the casting base 4 has a positioning groove corresponding to the positioning protrusion 14. Furthermore, the edge of the sleeper platform mold 10 is provided with a countersunk hole, and the sleeper platform mold 10 is detachably connected to the casting base 4 by a countersunk screw. In this embodiment, the casting base 4 is provided with a stepped hole that matches the sleeper platform. During installation, the sleeper platform mold 10 is placed in the corresponding stepped hole, and a screw hole is provided on the stepped surface of the stepped hole. The edge of the sleeper platform mold 10 is placed on the stepped surface of the stepped hole, and then locked with a countersunk screw. When the sleeper platform mold 10 is installed, the top of the sleeper platform mold 10 is flush with the top of the casting base 4.

[0027] In this embodiment, as Figure 1 As shown, a mandrel mounting hole is provided on the casting seat 4 between every two sleeper platform mold basins 10. A mandrel assembly 13 is installed in the mandrel mounting hole. The mandrel assembly 13 includes a conical sleeve, a screw, and a handle. The conical sleeve is threadedly connected to the screw, while the handle is installed on the top of the screw. The bottom of the screw is a smooth rod. Before the track slab is prefabricated, the bottom of the screw is fitted into the mandrel mounting hole. After the track slab is prefabricated, the mandrel assembly 13 can be hoisted to facilitate the hoisting and transportation of the prefabricated track slab.

[0028] In this embodiment, as Figure 1 As shown, an ultra-high partition plate 11 is installed inside the casting cavity 15. The shape of the ultra-high partition plate 11 matches that of the casting cavity 15. Flanges are provided on both the front and rear sides of the ultra-high partition plate 11. The front flange is detachably connected to the ultra-high side mold 5, and the rear flange is detachably connected to the standard side mold 6. In this embodiment, pin holes are provided on the flanges, and corresponding pin holes are also provided on the ultra-high side mold 5 and the standard side mold 6. After the ultra-high partition plate 11 is installed inside the casting cavity 15, its flanges are connected to the corresponding ultra-high side molds via pins. The connection between mold 5 and standard side mold 6 ensures the reliability of the installation position of the ultra-high partition 11. In this embodiment, the size of the casting cavity 15 can be changed by the ultra-high partition 11, and the ultra-high partition 11 can be installed in the corresponding position according to the required track plate size, thereby completing the prefabrication of the track plate that meets the requirements. Moreover, for some prefabricated plates with shorter lengths, several ultra-high partitions 11 can be set to allow for the simultaneous prefabrication of several track plates, thereby improving production efficiency.

[0029] In this embodiment, as Figure 2 and Figure 3 The support leg 1 includes a support rod, and a support seat is installed at the bottom of the support rod through several double nut locking assemblies. Therefore, the distance between the support rod and the support seat can be adjusted by the double nut assembly, thereby adjusting the length of the support leg 1 to adapt to the tilt of the base 3. The support rod, wedge plate 2 and base 3 are connected by bolt assemblies. Vertical through holes are opened on the wedge plate 2, and the screw of the bolt assembly passes through the corresponding through holes. In this embodiment, the track plate is a standard part, and its tilt angle is required. Therefore, the corresponding wedge plate 2 can be designed according to the design requirements of the tilt angle of the track plate. After the wedge plate 2 is installed, a track plate that meets the requirements can be cast.

[0030] In this embodiment, as Figure 1 As shown, two casting seats 4 are provided on the base 3, and the two casting seats 4 are connected by several spaced connectors 12, which can improve production efficiency.

[0031] In this embodiment, vibrators (not shown in the figure) are also installed on the front and rear sides of the hinge seat. There are three vibrators, which are evenly spaced. When the concrete is being poured, it is a fluid when it is solidified. By vibrating the vibrators, air bubbles in the concrete can be eliminated, the density of the concrete can be increased, and its strength and durability can be enhanced.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
