Description

Technical Field

[0001] This invention relates to the field of roller conveyor equipment technology, specifically to a roller conveyor cooling structure and cooling method. Background Technology

[0002] Roller conveyors, as a type of conveying equipment, run throughout the entire steel rolling production line. They are the most numerous, occupy the largest area, and are indispensable auxiliary equipment for conveying pipes. The function, layout, structure, and transmission method of roller conveyors vary depending on the main equipment they are located in. The structure and transmission method of roller conveyors not only affect the usability and reliability of the equipment but also have a direct impact on production efficiency and product quality.

[0003] Because the steel pipes being transported are heated to high temperatures, and the roller conveyor itself is a steel product with high thermal conductivity, prolonged contact between the high-temperature steel pipes and the roller conveyor can cause grease to melt, leak, and bearings to burn out. The impact on bearings is particularly severe; roller conveyor jamming will seriously affect subsequent production. Steel pipe transport is composed of many roller conveyors, each of which must be effectively cooled to ensure high-speed pipe transport. The roller conveyor cooling system is crucial. Existing technologies use coolant to directly cool the roller conveyor; however, due to the rapid heat conduction of metals, components connected to the roller conveyor are prone to overheating. Summary of the Invention

[0004] The purpose of this invention is to provide a roller cooling structure and cooling method, which can effectively solve the technical problem in the prior art that the components connected to the roller are prone to overheating due to the rapid heat conduction of metal.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A roller cooling structure includes a frame and a plurality of roller assemblies mounted on the frame. Each roller assembly includes a roller body and cooling assemblies mounted on both sides of the roller body.

[0007] The roller conveyor body is equipped with connecting shafts at both ends of the roller conveyor body, and the roller conveyor body and the connecting shafts are hollow inside.

[0008] The cooling assembly includes an outer jacket and a drive shaft. The outer jacket includes a connecting part and an outer cover. The connecting part is connected to the outer cover and forms a stepped surface at the connection. The drive shaft is rotatably mounted in the connecting part and a rotating sealing ring is provided between the drive shaft and the connecting part. The right end of the connecting part extends into the outer cover.

[0009] The outer cover is provided with a first mounting part, and the connecting shaft is rotatably provided with a second mounting part. The second mounting part is made of heat-insulating material. The connecting shaft is rotatably mounted inside the outer cover through a bearing, and a rotating sealing ring made of heat-insulating material is provided in the gap between the connecting shaft and the outer cover. The connecting part is fixedly mounted on the frame, and the drive shaft extending out of the connecting part is used to connect with the drive mechanism.

[0010] A connecting rod is provided on the first mounting part, and a guide hole is provided on the second mounting part. The connecting rod passes through the guide hole and is connected to a locking nut. A spring is fitted on the connecting rod, and the spring contacts the first and second mounting parts.

[0011] The drive shaft and the connecting shaft are connected by protrusions and grooves. The drive shaft is provided with a liquid inlet hole, which is connected to the inside of the connecting shaft. The outer cover is provided with a connection port, which is connected to the coolant through a pipe.

[0012] The drive shaft has a square protrusion at one end, and the connecting shaft has a square groove at one end that matches the square protrusion.

[0013] Further specifying, the square protrusion can be triangular, quadrilateral, pentagonal, or hexagonal, and the square groove matches the shape of the square protrusion.

[0014] The drive mechanism includes a motor and a reducer. The motor is connected to the drive shaft in the cooling assembly on the left or right side of the roller conveyor body through the reducer.

[0015] Further optimization involves having multiple connecting rods evenly distributed on the first mounting section.

[0016] The roller conveyor body is equipped with a support assembly inside.

[0017] Further optimization involves the support assembly including a support cylinder and support rods mounted on the support cylinder. The support rods are connected to the inner wall of the roller conveyor body to form a support structure.

[0018] The support cylinder has a guide slope on the side facing the coolant flow.

[0019] In addition, the present invention also discloses a roller cooling method, which includes using the above-mentioned roller cooling structure, wherein the connection ports of the cooling components on both sides of the roller body are connected to the cooling liquid system, so that the cooling liquid flows sequentially through the cooling component on the left side of the roller body, the roller body, and the cooling component on the right side of the roller body to achieve the purpose of cooling the roller body.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention achieves cooling of the roller conveyor body through a specially designed cooling assembly. In use, coolant is introduced into the outer cover from the connection port on the left side of the roller conveyor body. The coolant enters the flow channel formed between the outer cover and the connecting shaft, then passes through the bearing, enters the connecting shaft through the inlet hole on the drive shaft, flows through the roller conveyor body, and then enters the cooling assembly on the right side of the roller conveyor body. It then flows through the bearing in the right-side cooling assembly and exits through the connection port. This achieves rapid heat reduction. More importantly, since the bearing is immersed in coolant (typically cooling oil), heat dissipation is ensured while lubrication of the bearing is also achieved. Furthermore, because the second mounting part and the rotating sealing ring are made of heat-insulating material, heat from the connecting shaft is not directly transferred to the outer cover. Additionally, the drive shaft and connecting shaft are connected by protrusions and grooves, ensuring a gap filled with cooling oil during normal transmission. This invention effectively solves the technical problem in existing technologies where the rapid heat conduction of metal leads to overheating of components connected to the roller conveyor.

[0034] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] Example 1

[0036] See Figures 1-3 This embodiment discloses a roller cooling structure, including a frame 101 and a plurality of roller assembly 102 disposed on the frame 101. The roller assembly 102 includes a roller body 103 and cooling assembly 104 disposed on both sides of the roller body 103.

[0037] The roller conveyor body 103 is provided with connecting shafts 105 at both ends of the left and right sides, and the roller conveyor body 103 and the connecting shafts 105 are hollow inside.

[0038] The cooling assembly 104 includes an outer sleeve 106 and a drive shaft 107. The outer sleeve 106 includes a connecting part 108 and an outer cover 109. The connecting part 108 is connected to the outer cover 109 and a stepped surface 110 is formed at the connection. The drive shaft 107 is rotatably mounted in the connecting part 108 and a rotating sealing ring 111 is provided between the drive shaft 107 and the connecting part 108. The right end of the connecting part 108 extends into the outer cover 109.

[0039] The outer cover 109 is provided with a first mounting part 112, and the connecting shaft 105 is rotatably provided with a second mounting part 113. The second mounting part 113 is made of heat-insulating material. The connecting shaft 105 is rotatably mounted inside the outer cover 109 through a bearing, and a rotating sealing ring 111 made of heat-insulating material is provided in the gap between the connecting shaft 105 and the outer cover 109. The connecting part 108 is fixedly mounted on the frame 101, and the drive shaft 107 extending out of the connecting part 108 is used to connect with the drive mechanism.

[0040] A connecting rod 114 is provided on the first mounting part 112, and a guide hole is provided on the second mounting part 113. The connecting rod 114 passes through the guide hole and is connected to a locking nut 116. A spring 117 is fitted on the connecting rod 114, and the spring 117 contacts the first and second mounting parts.

[0041] The drive shaft 107 and the connecting shaft 105 are connected by a protrusion 118 and a groove 119. The drive shaft 107 is provided with a liquid inlet hole, which communicates with the interior of the connecting shaft 105. The outer cover 109 is provided with a connection port, which is connected to the coolant through a pipe.

[0042] This invention achieves cooling of the roller conveyor body 103 through a cooling assembly 104. In use, coolant is introduced into the outer cover 109 from the connection port on the left side of the roller conveyor body 103. The coolant enters the flow channel formed between the outer cover 109 and the connecting shaft 105, then passes through the bearing, enters the connecting shaft 105 through the inlet hole on the drive shaft 107, flows through the roller conveyor body 103, and then enters the cooling assembly 104 on the right side of the roller conveyor body 103. It then flows through the bearing in the right-side cooling assembly 104 and exits from the connection port. This achieves rapid cooling. More importantly, because the bearing is immersed in the coolant... In the cooling system, cooling oil is generally used, which ensures heat dissipation while also lubricating the bearings. Simultaneously, since the second mounting part 113 and the rotating sealing ring 111 are both made of heat-insulating material, the heat on the connecting shaft 105 is not directly transferred to the outer cover 109. Furthermore, the drive shaft 107 and the connecting shaft 105 are connected via a protrusion 118 and a groove 119, ensuring a gap between them during normal transmission, which is filled with cooling oil. This invention effectively solves the technical problem in the prior art where the rapid heat conduction of metal leads to overheating of components connected to the roller conveyor.

[0043] Figure 3 In the image, the arrow indicates the direction of coolant flow.

[0044] In practical use, the second mounting part 113 can support the connecting shaft 105, making the roller body 103 more stable when rotating.

[0045] The drive shaft 107 has a square protrusion at its end, and the connecting shaft 105 has a square groove at its end that matches the square protrusion.

[0046] Further optimization involves making the square protrusions triangular, quadrilateral, pentagonal, or hexagonal, with the square grooves matching the shape of the square protrusions.

[0047] This facilitates the transmission between the drive shaft 107 and the connecting shaft 105 in practical use.

[0048] The drive mechanism includes a motor and a reducer. The motor is connected to the drive shaft 107 in the cooling assembly 104 on the left or right side of the roller conveyor body 103 via the reducer.

[0049] In actual use, there are multiple connecting rods 114 that are evenly distributed on the first mounting part 112.

[0050] Example 2

[0051] This embodiment is a further optimization based on Embodiment 1. In this embodiment, a support assembly 120 is provided inside the roller conveyor body 103. The support assembly 120 includes a support cylinder 121 and a support rod 122 disposed on the support cylinder 121. The support rod 122 is connected to the inner wall of the roller conveyor body 103 to form a support structure.

[0052] The support components 120 make the roller conveyor body 103 more stable as a whole.

[0053] Further optimization involves providing a guide slope 115 on the side of the support cylinder 121 facing the coolant flow, which facilitates the diversion of coolant and allows the coolant to flow faster between the support cylinder 121 and the roller conveyor body 103, thereby improving the heat dissipation effect.

[0054] Example 3

[0055] This embodiment discloses a roller cooling method, which includes using the roller cooling structure described in Embodiment 1. The connection ports of the cooling components 104 on both sides of the roller body 103 are connected to the coolant system, so that the coolant flows sequentially through the cooling component 104 on the left side of the roller body 103, the roller body 103, and the cooling component 104 on the right side of the roller body 103 to achieve the purpose of cooling the roller body 103; the coolant system is used to provide flowing coolant.
