[0002] Metro rail steel is mainly used for laying metro lines, providing support and guidance for the operation of metro trains. Metro rail steel has high strength and good wear resistance, and can withstand the huge weight of metro trains. Whether empty or fully loaded, metro rail steel can remain stable. Metro rail steel is produced by casting to obtain blank products, and then the products are further processed to obtain the product that meets the requirements of Guigang.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example

[0031] Reference Figures 1-5 This utility model provides a technical solution: a subway rail steel template casting device, including a frame 1, a positioning mechanism 3 and a reinforcing mechanism 4, and a barrier 2 is set inside the frame 1. The positioning mechanism 3 includes a rectangular plate 31, which is set outside the frame 1 and the barrier 2. An insertion hole 311 is set on the outer surface of the rectangular plate 31. A limiting plate 32 is inserted into the insertion hole 311. A threaded post 33 is set inside the frame 1 and the barrier 2. The reinforcing mechanism 4 is set at the bottom of the frame 1 to improve the connection stability between the frame 1 and the barrier 2.

[0032] By installing threaded posts 33 inside the frame 1 and the enclosure 2, with a rectangular plate 31 fitted onto the threaded posts 33 and a nut 12 installed on the threaded posts 33, the enclosure 2 and the frame 1 can be stably connected by screwing the nut 12 onto the threaded posts 33 and clamping the rectangular plate 31. By inserting the limiting plate 32 into the interior of the rectangular plate 31 and pressing the enclosure 2, the positioning effect of the enclosure 2 can be further improved to meet the requirements of use.

[0033] In a preferred embodiment, the reinforcing mechanism 4 includes a groove 41, a slider 42, and an extrusion block 43. The groove 41 is located at the bottom of the frame 1, and the slider 42 is provided inside the groove 41. The extrusion block 43 is stably installed at the top of the slider 42, and a round hole 5 is provided on the side of the extrusion block 43.

[0034] In practical use, to improve the installation stability of the enclosure 2, a sliding groove 41 is provided at the bottom of the frame 1. The frame 1 is composed of a vertical plate and a bottom plate, which are also a whole. The device sets the sliding groove 41 on the bottom plate. By moving the slider 42, the pressing block 43 will move. The pressing block 43 will press the concave surface of the enclosure 2 to position the enclosure 2 and improve the installation stability of the enclosure 2. In addition, a threaded hole 6 is provided at the bottom of the frame 1 and the outside of the sliding groove 41. A positioning screw 7 is provided inside the threaded hole 6. The positioning screw 7 passes through the inside of the round hole 5. After controlling the pressing block 43 to move to a certain position, the positioning screw 7 can be used to position the pressing block 43. After the pressing block 43 is positioned, it can stably support the enclosure 2.

[0035] Through holes 8 are respectively provided on the outer surfaces of frame 1 and enclosure 2, and the positions of the through holes 8 on the two correspond to each other. Threaded post 33 is set inside the through hole 8 and extends out of the through hole 8. When the enclosure 2 is installed inside the frame 1, it is necessary to ensure that the positions of the through holes 8 on the enclosure 2 and the through holes 8 on the frame 1 correspond. After the positions of the two through holes 8 are aligned, the threaded post 33 can be inserted into the through hole 8. In this device, the two ends of the threaded post 33 are provided with threaded rings, and the middle part is set to a smooth state.

[0036] The enclosure 2 is designed with an inwardly concave arc shape. A connecting plate 9 is provided on the side of the enclosure 2. The connecting plate 9 fits against the inner side of the frame 1. When the enclosure 2 is installed on the inner side of the frame 1, it will drive the connecting plate 9 to be installed on the inner side of the frame 1, so that the outer surface of the connecting plate 9 is in close contact with the inner wall of the frame 1. A sealing element is also provided at the contact point to ensure that molten steel does not leak out and to facilitate use.

[0037] The top of the frame 1 is set as an opening. A fixing plate 10 is fixedly installed on the outer surface of the frame 1, and a circular hole 11 is opened on the upper surface of the fixing plate 10. The fixing plate 10 is installed on the outside of the frame 1. The fixing plate 10 is provided with a circular hole 11. The device can be moved by lifting with external equipment, and the usage position of the device can be changed and adjusted according to the actual use.

[0038] A nut 12 is threaded onto the threaded post 33, and a rectangular plate 31 is positioned inside the nut 12 to improve the installation stability of the threaded post 33.

[0039] Specifically, the working process or principle of a subway rail steel formwork casting device is as follows: The rail steel casting production method involves pouring molten steel into the interior of a formwork, which then cools and solidifies inside the formwork. However, the formwork is not a single unit but is composed of several modular formworks. This requires ensuring stable connections between the formworks. If the connections are not stable, the formwork will expand during the pouring of molten steel, affecting the processing of the product. Therefore, this device was designed to solve this problem.

[0040] This device can stably connect the frame 1 and the enclosure 2 together, preventing molten steel from being poured into the enclosed space and causing the enclosure 2 to expand, thus improving the usage effect. The specific operation is as follows: place the frame 1 at the location to be processed, and then assemble the mold. Place the enclosure 2 inside the frame 1. The frame 1 consists of two vertical plates and a base plate. There are two vertical plates, which are symmetrically installed on the base plate. Place the enclosure 2 inside the two vertical plates and align the through holes 8 on the enclosure 2 with the through holes 8 on the frame 1 so that the threaded post 33 can be installed inside the frame 1 and the enclosure 2. Then connect the frame 1 and the enclosure 2 together for use.

[0041] Insert the threaded post 33 into the through hole 8 on the frame 1 and the enclosure 2, with both ends of the threaded post 33 positioned on the outside. Then, fit the rectangular plate 31 onto the threaded post 33 on the outside and rotate the two rectangular plates 31 onto the outer surfaces of the frame 1 and the enclosure 2 respectively. Then, screw the nut 12 onto the threaded post 33 and press the rectangular plate 31 to stably install the threaded post 33 inside the frame 1 and the enclosure 2. Finally, insert the limiting plate 32 into one end of the rectangular plate 31. The inner side of the limiting plate 32 will be in close contact with the outer surface of the enclosure 2 to position the enclosure 2. Connect the other positions on the enclosure 2 to the frame 1 in the same way to stably install the enclosure 2 on the frame 1 for easy use.

[0042] To improve the stability of the enclosure 2 on the frame 1, after positioning the enclosure 2, the extrusion block 43 can be moved. The extrusion block 43 is controlled to move at the bottom of the frame 1 and extrudes the enclosure 2. Then, the positioning screw 7 is used to stably install the extrusion block 43 on the frame 1, thereby improving the stability of the enclosure 2. Finally, molten steel is added to the inside of the frame 1 and the enclosure 2. Through cooling, the molten steel can be solidified to form a product. After the product is solidified, the enclosure 2 can be disassembled and the product can be taken out, thus completing the operation.
