Description

[Technical field]

[0001] The utility model relates to the technical field of rolling mills, in particular to a rough rolling electromagnetic clutch protection device for a hot rolling mill. [Background technology]

[0002] Rough rolling is a process of stacking several layers of steel plates together and hot rolling them into an intermediate billet with a thickness of about 35mm using a four-roll rolling mill. The electromagnetic clutch in the rough rolling area is located between the two main motors, and the shoulder beam is located in front of the clutch, and it moves up and down relative to the carbon brush base during rolling.

[0003] During the rolling process, a large amount of iron oxide and water vapor will fall onto the electromagnetic clutch, causing the outer gear sleeve and inner gear head of the electromagnetic clutch to rust and peel off, and the tooth surface to be uneven, causing the clutch to jam; it may even cause the outer gear sleeve and inner gear head of the clutch to rust and lock, thus causing the electromagnetic clutch to fail; at the same time, it will also corrode the carbon brushes and terminals of the clutch, causing poor contact between the circuit and the carbon brushes.

[0004] In response to the above problems, Chinese utility model patent CN202120093072.0 discloses a hot rolling mill rough rolling electromagnetic clutch protection device and an electromagnetic clutch. A protective cover is arranged on the electromagnetic clutch, and a vent pipe is arranged on the protective cover. Dry compressed air is introduced into the interior of the protective cover through the vent pipe. The compressed air is ejected through the gap between the protective cover and the bottom plate to form a positive air pressure around the clutch, thereby effectively preventing water vapor and iron oxide from approaching the clutch to achieve a protective effect. However, the technical solution lacks a pipe to guide the flow of compressed air, so that the gas can only flow on one side of the clutch. At the same time, since the compressed air flows out through the gap between the protective cover and the bottom plate, the installation of the protective cover will be unstable, and it is easy to shake and make noise, affecting nearby workers. [Contents of the utility model]

[0027] like Figure 1-3 As shown, in one embodiment of the utility model, a hot rolling mill rough rolling electromagnetic clutch protection device includes a base plate 2, a support member 3, a baffle 4, a protective cover 5 and an air supply assembly. The clutch body 1 is detachably mounted on the base plate 2 through a mounting seat 11, the support member 3 is arranged between the base plate 2 and the baffle 4, the protective cover 5 is covered on the clutch body 1, and the air supply assembly is installed on the protective cover 5.

[0028] In detail, there are two support members 3 , which are symmetrically arranged on two opposite sides of the bottom of the base plate 2 , specifically left and right sides or front and back sides, and the lower ends of the support members 3 are connected to the baffle 4 .

[0029] Preferably, the support member 3 is in an inverted T-shape, and this shape can increase the contact area between the support member 3 and the baffle 4 and improve the connection stability.

[0030] The protective cover 5 is provided with long strip openings 52 on two side surfaces corresponding to the length direction of the clutch body 1. The protective cover 5 is arranged on the clutch body 1 and its bottom edge is detachably connected to the bottom plate 2. The two ends of the clutch body 1 extend out of the protective cover 5 through the long strip openings 52.

[0031] Specifically, two opposite sides of the top of the base plate 2 are provided with card slots 21, and two opposite bottom edges of the protective cover 5 are provided with card blocks 51. The protective cover 5 and the base plate 2 are connected by the card slots 21 and the card blocks 51, and the connection is stable, which can prevent the protective cover 5 from shaking due to gas.

[0032] The air supply assembly includes an air supply pipe 6, the upper end of which is connected to an external air pump, the lower end of which passes through the top of the protective cover 5, enters the protective cover 5 and is connected to the vertical end of the three-way joint 7, and the two horizontal ends of the three-way joint 7 are connected to an air distribution pipe 8, which is horizontal to the length direction of the clutch body 1, and the end of the air distribution pipe 8 is connected to a gas diverter 9, and the two gas diverters 9 are respectively located directly above the two sides of the clutch body 1, and the gas outlet of the gas diverter 9 faces downward, and the ejected gas flows on both sides of the clutch body 1, thereby effectively preventing water vapor and iron oxide from approaching the clutch, and the protective effect is good. Correspondingly, an exhaust hole 22 is opened on the bottom plate 2 to facilitate the discharge of compressed air, reduce the discharge pressure, avoid the influence of airflow on the protective cover 5, and improve the stability of the installation of the protective cover 5.

[0033] Preferably, a viewing window 12 is provided on the top of the protective cover 5 for easy observation.

[0034] Preferably, a pair of handles 10 are provided on the top of the protective cover 5 to facilitate moving the protective cover 5 .

[0035] Preferably, the protective cover 5 is also detachably connected with a blocking limit plate (not shown in the figure), and the specific detachable connection method is a snap connection. The blocking limit plate is used to close the remaining part of the long strip opening 52 to prevent iron oxide and water vapor from entering the protective cover 5 through the long strip opening 52.

[0036] When in use, first start the external air pump to allow dry compressed air to enter the three-way joint 7 through the ventilation pipe 6, and then be divided into two streams, entering the two air distribution pipes 8 in turn, and finally entering the corresponding gas diverter 9 respectively. The gas diverter 9 blows compressed air toward the clutch body 1, so that the gas inside the protective cover 5 flows downward and is discharged through the long strip opening 52 and the exhaust hole 22, preventing a large amount of iron oxide, water vapor and dust from falling on the electromagnetic clutch during the rough rolling process of the hot rolling mill, solving the problem that the prior art lacks a pipeline to guide the flow of compressed air, so that the gas can only flow on one side of the clutch. At the same time, since the compressed air flows out through the gap between the protective cover 5 and the base plate 2, the installation of the protective cover 5 will be unstable, easy to shake and make noise, affecting nearby workers.

[0037] To sum up, the protective equipment of the utility model has the advantages of gas diversion and stable connection. It effectively solves the problems in the prior art that the gas can only flow on one side of the clutch and the compressed air flows out through the gap between the protective cover and the bottom plate, resulting in unstable installation of the protective cover and easy shaking and noise making. It is highly practical.
