Description

Technical Field

[0001] This utility model relates to the field of railway rail maintenance, specifically a railway rail cooling device. Background Technology

[0002] Rail bulging refers to the phenomenon where steel rails expand due to increased temperature in high-temperature environments, commonly known as "rail bulging" or "rail runaway." This phenomenon mainly occurs because the internal temperature and pressure of the rails exceed the resistance of the track frame, causing the rails to bend and deform. As the rail temperature rises, the deformation gradually increases, eventually potentially leading to a sudden bulge of the track frame, causing it to deviate from the center of the track; this phenomenon is called "track runaway."

[0003] The rails should be inspected when the ambient temperature exceeds 35 degrees Celsius. For every 1 degree Celsius increase in rail temperature, a 1-meter-long rail will expand by 0.0118 millimeters.

[0004] Every year during periods of high temperatures, rails need to be cooled. There are two common methods for cooling rails: the first is to wrap the rails with anti-swelling cloth and then pour water on them to cool them down; the second is to push ice blocks along the rails to cool them down. For example, in 2022, due to continuous high temperatures, railway workers in Yiliang County, Zhaotong, Yunnan Province, used the method of pushing ice blocks by hand to cool the rails. However, this method has two drawbacks. Since small ice blocks are usually used, railway workers need to bend over to press and push the ice. Working with their backs bent over for a long time in high-temperature environments can easily lead to injuries. In addition, the shape of ordinary rectangular ice blocks does not fit the shape of the rails very well, resulting in low cooling efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a railway rail cooling device that serves as a freezing mold for ice blocks and also as a support plate during the ice-pushing process on the rails. When used in conjunction with support rods, it facilitates the pushing of ice by railway workers.

[0006] To achieve the above objectives, a railway rail cooling device is provided, comprising: a bottom mold and a top mold. The bottom mold has a U-shaped structure, and the top mold has a J-shaped structure. The bottom mold and the top mold form a cuboid cavity. The bottom mold is composed of a bottom surface and left and right side surfaces, and the top mold is composed of a front, rear, and top surface and a stop block. A support rod is provided on the bottom surface of the bottom mold.

[0007] Preferably, the connection method between the support point of the strut and the bottom surface of the bottom mold includes, but is not limited to, movable riveting and hinge, and the connection method between the support point of the strut and the strut is threaded connection.

[0008] Preferably, a sealing structure is provided at the connection between the bottom mold and the top mold.

[0009] Preferably, the cover film is provided with water injection holes, and the top surface of the cover film is provided with support legs.

[0010] Preferably, the support legs are arranged at the four corners of the top surface of the film covering.

[0011] Beneficial effects: Ordinary ice cubes need to rub on the track for a long time to become a U-shaped, while the ice cubes demolded by the present utility model are in a U-shape, having a higher degree of fit with the rail and higher cooling efficiency; the mop-shaped structural design is convenient for railway workers to operate, and the operating workers no longer need to bend down, with better comfort.

[0016] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0017] As Figure 1 , Figure 2 , the bottom mold and the cover mold can be assembled into a hollow cuboid structure. The bottom mold and the cover mold are respectively composed of 3 faces of a cuboid. One structure that can realize the assembly of the bottom mold and the cover mold is to provide a chute at the edge, and a sealing rubber ring is arranged in the chute. At the same time, the mortise and tenon structure can also realize the assembly structure of the bottom mold and the cover mold. Since the structure at the assembly joint can be realized in various ways, which belongs to the basic knowledge in the field of box design, it is not within the scope of the present utility model.

[0018] The functions of the bottom mold and the cover mold are to store water and freeze it into ice. The structure of the stop block on the cover mold makes the ice cubes in a U-shape after demolding. The U-shaped ice cubes have a higher degree of fit with the rail. The support rod is connected to the bottom mold by means of movable riveting or hinging. Its structural characteristics are similar to a mop. Railway workers can press, support and push the ice without bending down, and relieving work fatigue means improving work efficiency.

[0019] Embodiment 1

[0020] Comparing the curves of ice block length and cooling rate in the experiment, it can be seen from the graph that the longer the ice block is, the closer it is to the extreme value. From the perspective of ease of manual operation, the length needs to be less than 1 meter. Therefore, the optimal working efficiency is achieved when the ice block length is between 40cm and 100cm.

[0021] In the process of freezing ice blocks in molds, cold storage is usually used for stacking and freezing. If the water injection hole is blocked by other molds above during the stacking process, the freezing efficiency inside will be greatly reduced. The function of the support feet on the cover mold is to isolate the cover mold from other bottom molds and accelerate the freezing process.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
