Description

Technical Field

[0001] The utility model relates to the technical field of casting moulds, in particular to a railway coal loading and dust suppression integral roadbed steel mould. Background Art

[0002] my country's energy structure is dominated by coal. As the most important type of cargo in my country's freight transportation, coal often needs to be transported over long distances. In order to reduce the large amount of coal dust generated during the transportation of coal, the conventional method of water sprinkling is used to reduce dust. This method is relatively universal and is commonly used for dust-generating points in various working processes of railway coal transportation. Its disadvantage is that it consumes a lot of water and electricity resources, and the amount of water spraying is more harmful to the railway foundation, which is easy to cause foundation settlement, resulting in transportation suspension and high maintenance costs.

[0003] The dust suppression integral ballast is designed on the basis of the trackless track and concrete integral crossing slab, combined with the existing station laying site and usage conditions. The integral ballast is composed of prefabricated track slabs and lower prefabricated components, and the structural reinforcement and fastener system are optimized. It not only adapts to the passing capacity of densely packed vehicles, but also reduces the manufacturing cost by 1 / 5, meeting the needs of low-cost operation. It is undoubtedly the most suitable choice for railway coal loading dust suppression and has a good market application prospect.

[0004] At present, the commonly used forming steel molds for concrete track slabs, sleepers, etc. are welded one-piece structures. Due to the relatively large size of the overall roadbed, when using an one-piece structure mold for production, too many welding parts and a large welding area will cause the mold to deform, and the shape and size of each part of the product cannot be guaranteed. In addition, it is inconvenient to transport and demold during use, which seriously affects production efficiency. Utility Model Content

[0005] The utility model provides a railway coal loading dust suppression integral roadbed steel mold, which is combined and connected by a lateral side mold and a longitudinal side mold with a bottom mold to form a phase-separated model system, and a casting cavity is formed on a supporting platform after the combination, which is split after the casting is completed, so as to facilitate the splitting, transportation and demoulding operations, and is easy to use and improves production efficiency.

[0006] In order to solve the above technical problems, the utility model provides a technical solution: a railway coal loading dust suppression integral roadbed steel mold, comprising a bottom template, a transverse side template and a longitudinal side template, the lower side of the bottom template is arranged on a supporting platform, the two ends of the transverse side template are provided with grooves, the two ends of the longitudinal side template are provided with protrusions, the two transverse side templates are arranged on the transverse sides of the bottom template, and the bottom of the transverse side template is hinged to the side plate demoulding slide assembly arranged on the supporting platform, the two longitudinal side templates are arranged on the longitudinal sides of the bottom template, and are placed on the longitudinal side plate brackets, when the transverse side template is flipped upward, the protrusion on the longitudinal side template extends into the groove on the transverse side template, and the connection between the transverse side template and the longitudinal side template and between the transverse side template and the bottom template is realized by connecting bolts, and a casting cavity is surrounded on the bottom template;

[0007] Two parallel rows of rail groove connectors are arranged on the bottom template in the casting cavity, and fixing bolts penetrating the bottom template from outside to inside are arranged on the bottom template, and the sleeve is threadedly connected to the rail groove connector through the fixing bolts.

[0008] Furthermore, the side panel demoulding slide assembly includes a guide rod and a sleeve bearing, the sleeve bearing is horizontally arranged on the support platform, one end of the guide rod extends into the sleeve bearing and slides along the axis, and the other end of the guide rod is hinged to the bottom of the lateral side template.

[0009] Furthermore, a vibrator is provided on the side of the support platform through a hanging plate, and the vibrator includes a flat vibrator and an inserted vibrating rod.

[0010] Furthermore, the support platform includes a vertical I-beam, a transverse I-beam and support legs, at least two vertical I-beams are arranged parallel to each other, the vertical I-beams are connected by the transverse I-beam to form a placement surface for placing the bottom template, one end of at least two support legs is connected to the vertical I-beam to support the placement surface, and the other end of the support leg is provided with a bottom support plate.

[0011] Furthermore, an adjustment bolt is provided between the support leg and the bottom support plate.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model forms a phase-separated model system by combining and connecting the lateral side template and the longitudinal side template with the bottom template. After the combination, a casting cavity is formed on the supporting platform.

At the same time, the position of the embedded sleeve is fixed through the bottom mold with special bolts, which fully ensures the installation accuracy of the fastener system. At the same time, the fixing bolts penetrate the bottom mold from the outside to the inside. After pouring is completed, the fixing bolts can be disengaged from the sleeve by twisting them, thereby completing the accurate embedding of the sleeve in the product.

[0017] 5. The vibrator of the utility model adopts a vibration mode combining side plate + insertion. The vibration of the flat plate vibrator is combined with the uniform vibration of the inserted vibrating rod to solve the problem of unstable quality.

[0018] 6. The support legs of the utility model enable the casting cavity to have a certain height, which is convenient for production. A bottom support plate is provided at the bottom of the support legs to increase the contact area with the ground and ensure the stability of the support.
