Description

Technical Field

[0001] This utility model relates to the field of railway bearing cooling technology, specifically a uniform cooling device for heat treatment of high-toughness railway bearings. Background Technology

[0002] Railway bearings are critical components in railway bridges and track structures, used to support the superstructure, transfer loads, and adapt to deformation. Heat treatment refers to a process that alters the internal structure of metallic materials by controlling the heating, holding, and cooling processes, thereby obtaining the desired mechanical and physical properties. In railway bearing manufacturing, heat treatment is mainly used to improve the strength, toughness, wear resistance, and fatigue resistance of the bearing materials, extending their service life. Utilizing the high specific heat capacity and high heat transfer efficiency of water, rapid cooling is achieved through water coolers or cooling towers to cool the railway bearings.

[0003] When the cooling device is in use, metal residue will fall off during the metal quenching and cooling process. After a long period of time, the metal residue needs to be cleaned. When cleaning the residue, all the coolant in the cooling pool needs to be drained. The coolant cannot be reused, which results in waste of coolant. Utility Model Content

The drain pipe 102 is fitted with a sealing plug. The cooling box 1 is made of 304 stainless steel or Q235B carbon steel, with an anti-corrosion coating to ensure corrosion resistance and load-bearing capacity. The box body is equipped with a flow guide plate to promote the circulation of coolant. An observation window is set on the side wall. The drain pipe 102 is equipped with a quick-release flange interface. The sealing plug adopts a double insurance design of rubber sealing ring and threaded locking to prevent leakage. The support feet 101 are adjustable shock-absorbing support feet, including a screw adjustment structure and a rubber buffer pad to adapt to uneven ground. The cooling box 1 is equipped with a first mounting frame 2 and a second mounting frame 3. The second mounting frame 3 is equipped with a filter assembly 9.

[0025] The second mounting frame 3 includes two first side plates 4 and a second side plate 5. Mounting grooves 6 are provided on the side walls of both the first side plates 4 and the second side plates 5. The two first side plates 4 and the second side plates 5 constitute a frame. The mounting grooves 6 are provided on the inner wall of the frame. The first side plates 4 are fixed, while the second side plates 5 are designed to be detachable and are connected by bolts for easy maintenance. The mounting grooves 6 are fitted with copper wear-resistant bushings to reduce the rotational friction of the threaded rod 7.

[0026] Threaded rods 7 are installed at both ends inside the mounting slot 6. The filter assembly 9 is movably mounted on the threaded rods 7. The threaded rods 7 are threaded to fit a threaded cylinder 8. The surfaces of the threaded rods 7 and the threaded cylinder 8 are chrome-plated for rust prevention. The threaded cylinder has a built-in self-lubricating bearing, making it easy to tighten. The threaded cylinder 8 is located at the top of the filter assembly 9.

[0027] The filter assembly 9 includes a first filter cloth 901, a second filter cloth 902, and a connecting cloth 903. The four side walls of the first filter cloth 901 and the second filter cloth 902 are all connected to the connecting cloth 903. A drawstring 904 runs through the inside of the connecting cloth 903. Hanging rings 905 are installed at both ends of the drawstring 904. The hanging rings 905 are sleeved on the threaded rod 7. The threaded cylinder 8 is set at the top of the hanging rings 905. The first filter cloth 901 is an 80-mesh stainless steel woven mesh to intercept larger particles of residue. The second filter cloth 902 is a 200-mesh polyester fiber filter cloth to adsorb fine metal powder. The connecting cloth 903 is made of corrosion-resistant silicone material and has a folded accordion structure to adapt to the deformation when the drawstring 904 is tightened. The drawstring 904 is a Kevlar fiber rope. The hanging rings 905 have a spring locking device to prevent loosening.

[0028] The first mounting frame 2 is movably positioned at the top of the second mounting frame 3. Two connecting plates 201 are installed on the top surface of the first mounting frame 2. The connecting plates 201 are L-shaped plates. A handle 202 is installed on the top surface of the connecting plates 201. A filter screen 203 is set inside the first mounting frame 2.

[0030] When uniformly cooling the heat-treated high-toughness railway bearings using a cooling device, coolant is poured into the cooling tank 1. The railway bearings to be cooled are placed on the filter screen 203 of the first mounting frame 2. The railway bearings are cooled by the coolant inside the cooling tank 1. During cooling, the metal residue carried by the railway bearings settles and falls onto the filter assembly 9 inside the second mounting frame 3 at the bottom of the first mounting frame 2. After cooling, the seal inside the drain pipe 102 is removed, allowing the coolant inside the cooling tank 1 to be discharged completely into an external collection device, thus facilitating the cooling process. The liquid is reused. The pull ring 303 is flipped so that it is perpendicular to the extension plate 301. The handle 202 is pulled, and the slide 204 is separated from the extension plate 301, the hinge 302 and the pull ring 303, so that the first mounting frame 2 inside the cooling box 1 can be taken out. The cooled railway support is then taken out. The threaded cylinder 8 on the threaded rod 7 is rotated, the hanging ring 905 is removed, and the rope 904 is retracted, so that the first filter cloth 901 and the second filter cloth 902 are closed, and the metal residue is collected. The filter assembly 9 is separated from the second mounting frame 3, which further facilitates the cleaning of the metal residue.
