[0022] 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 function 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.
[0023] Referring to Figures 1-4 , an embodiment provided by the present utility model, a rotatable closing device for a rolling mill, includes a rolling mill body 1. Two rotary closing doors 4 are correspondingly installed on the outer side of the rolling mill body 1. Both of the two rotary closing doors 4 can rotate independently. A first chute 2 is provided at the inner end of the rolling mill body 1, and there are two first chutes 2, which are corresponding up and down. A second slider 11 is slidably connected inside the first chute 2, and a rotating shaft 13 is rotatably connected inside the second slider 11. By setting the rotating shaft 13, the self-rotation of the rotary closing door 4 can be realized, and under the action of the second slider 11 and the first chute 2, the rotary closing door 4 can be pushed after it rotates;
[0024] The other end of the rotating shaft 13 is fixedly connected to the upper and lower ends of the rotary closing door 4. A fixed part 3 is fixedly connected to the outer surface of one of the rotary closing doors 4. Translating the opened rotary closing door 4 along the track direction of the first chute 2 to the adjacent rotary closing door 4 or the door frame can realize the opening of the to-be-rotated closing door 4. Therefore, the number of rotary closing doors 4 to be opened can be selected according to needs, and the opening operation is simpler and easier to operate. Moreover, when one rotary closing door 4 is opened, the other rotary closing door 4 at the other end is in a closed state, which can ensure that the oil leakage is minimized. At the same time, when all the rotary closing doors 4 are opened and all translated to one side, the entire closing door occupies a small space, and as much space as possible can be reserved for the maintenance equipment to pass through;
[0025] A screw rod 7 is rotatably connected inside the fixing member 3, and a bearing 6 is installed at the connection between the screw rod 7 and the fixing member 3. By setting the bearing 6, the stability of the screw rod 7 during rotation can be improved;
[0026] One end of the screw rod 7 passes through the fixing member 3 and is fixedly connected to a handle 5. The other end of the screw rod 7 located inside the fixing member 3 is partially threadedly connected to a bolt block 8. Second sliding grooves 9 are formed at both the upper and lower ends of the bolt block 8. The fixing member 3 is provided with an opening at the side corresponding to the bolt block 8 for the bolt block to pass through, and a first slider 10 is fixedly connected to the fixing member 3 at the connection opening with the bolt block 8. The first slider 10 is slidably connected inside the second sliding groove 9. Rotating the handle 5 drives the screw rod 7 to rotate. Under the action of the threaded connection, the bolt block 8 retracts inward. At this time, the bolt block 8 releases the restriction on the rotating closing door 4, and the first slider 10 and the second sliding groove 9 can ensure the restricting ability of the bolt block 8, thereby improving the stability of the bolt block 8 during movement.
[0027] Grooves 16 are formed at both ends of the rolling mill body 1. One end inside the groove 16 is fixedly connected to a spring 15. The other end of the spring 15 is fixedly connected to a limiting plate 14. The other end of the limiting plate 14 is fixedly connected to a positioning block 17, and the positioning block 17 is disposed through the rolling mill body 1. A positioning groove 12 is formed on the rotating closing door 4. The positioning block 17 corresponds to the positioning groove 12. The staff pulls the limiting plate 14 to move outward. Under the action of the spring 15, the limiting plate 14 drives the positioning block 17 to leave the inside of the positioning groove 12. The two locking components can ensure the sealing performance of the rotating closing door 4 when it is closed, and can prevent loosening during the closing process. At the same time, in order to improve the sealing performance of the entire rotating closing door 4 during use, a sealing strip can be arranged around its outer end to improve the sealing performance of the entire device. When the rotating sealing door 4 needs to be closed, the rotating handle 5 at the outer end of the fixing member 3 is rotated in the reverse direction to drive the screw rod 7 to rotate. Under the restriction of the threaded connection and the first slider 10 and the second sliding groove 9, the bolt block 8 is driven to move outward. At this time, the bolt block 8 can abut against the outer surface of the other rotating door sealing door 4. The two rotating sealing doors 4 directly abut against each other, and the clamping of the rotating sealing door 4 can be realized by cooperating with the positioning blocks 17 and the positioning grooves 12 at the other two ends, thereby realizing the closing operation of the rotating sealing door.
[0028] Working principle: When the device is used, first, one of the rotary closed doors 4 needs to be opened, and the handle 5 is turned to drive the screw 7 to rotate. Under the action of the threaded connection, the bolt block 8 is retracted inward. At this time, the bolt block 8 releases the restriction of one rotary closed door 4 on the other rotary closed door 4. Then the staff pulls the limit plate 14 to move outward. Under the action of the spring 15, the limit plate 14 drives the positioning block 17 to leave the inside of the positioning groove 12. At this time, the staff can drive the rotary closed door 4 to rotate through the rotating shafts 13 at the upper and lower ends, and then along the first The track direction of a slide 2 can translate the opened rotary closed door 4 to the adjacent rotary closed door 4 or door frame, so that the rotary closed door 4 to be opened can be realized. Therefore, the number of rotary closed doors 4 to be opened can be selected according to the needs, and the opening operation is simpler and easier to operate. Moreover, when a certain rotary closed door 4 is opened, the rotary closed door 4 at the other end is in a closed state, which can ensure that the oil droplets leak as little as possible. At the same time, when all the rotary closed doors 4 are opened and translated to any side, the entire closed door occupies a small space, and the largest possible space can be reserved for the maintenance equipment to pass through. Therefore, the utility model realizes the technical effects of taking into account the opening and closing at any time, sealing the oil mist to the greatest extent, and facilitating the transportation of the maintenance equipment.
[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
