DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

When the combination of technical solutions is mutually contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0026] When the embodiments give numerical ranges, it should be understood that, unless otherwise stated by the present application, both endpoints of each numerical range and any number between the two endpoints can be selected. Unless otherwise defined, all technical and scientific terms used in the present application are consistent with the mastery of the prior art by those skilled in the art and the description of the present application. Any method, equipment and material of the prior art similar or equivalent to the method, equipment and material described in the embodiments of the present application can also be used to realize the present application.

[0027] In the related art, the rolling bearing installed in the bearing seat of the finishing work roll is expensive, and after being used for a period of time, the bearing seat needs to be disassembled, cleaned, inspected, measured and maintained to reduce the risk of bearing burnout. There are two existing bearing maintenance operation modes, the first one is to manually remove the mop of the bearing seat, and then use the existing equipment to disassemble, clean, inspect and maintain the bearing seat. This mode needs a long operation time and also has the risk of installation quality; the second maintenance mode is to use a lifting device to hoist the bearing seat on a simple support for maintenance without removing the mop. In this case, the operator needs to work on a higher platform, and the simple support has low stability, which has a very high safety risk for personnel and equipment, and affects the operation efficiency.

[0028] This utility model provides a bearing housing flipping device, including a drive structure 1, a rotating shaft 2, a fixed frame 3, and an installation mechanism 4 for mounting the bearing housing to be replaced; wherein, the rotating shaft 2 is rotatably connected to the fixed frame 3, the installation mechanism 4 is connected to the rotating shaft 2 and moves synchronously with the rotating shaft 2; the drive mechanism drives the installation mechanism 4 to rotate around the axis of the rotating shaft 2, so that the bearing housing to be replaced rotates from a first angular position to a vertical position.

[0029] It is important to know that the bearing housing of the finishing mill work roll is large in size and weight, and the clearance between the bearing and the bearing housing is very small. The bearing housing needs to be rotated to a vertical position before the bearing can be removed. The bearing housing to be replaced has a lifting eye hole, and the bearing housing to be replaced is lifted onto the mounting mechanism 4 by a lifting device to complete the subsequent flipping.

[0030] In this embodiment, the drive mechanism drives the mounting mechanism 4 to rotate around the rotating shaft 2, which enables the bearing housing to be replaced placed on the mounting mechanism 4 to rotate to a vertical position, so as to facilitate the replacement of the bearing in the bearing housing. The structure of the mounting mechanism 4 is relatively simple, and the operation is relatively safe and convenient. It can greatly improve the efficiency of bearing maintenance, thereby improving production efficiency and reducing safety risks.

[0031] In one embodiment, the mounting mechanism 4 includes a horizontal mounting surface 41 and a vertical mounting surface 42. The vertical mounting surface 42 has a through hole 421 for the mop with the bearing seat to be replaced to pass through. A guide sleeve 422 adapted to the mop with the bearing seat to be replaced is provided in the through hole 421. The guide sleeve 422 is provided along the extension direction of the horizontal mounting surface 41.

[0032] It should be noted that the bearing housing to be replaced is assembled onto the mounting mechanism 4 by means of hoisting.

[0033] In this embodiment, the vertical mounting surface 42 has a through hole 421 for the mop to pass through, and the guide sleeve 422 is disposed in the through hole 421 and is disposed along the extension direction of the horizontal mounting surface 41. This allows the mop to be smoothly guided into the mounting mechanism 4, improving installation efficiency and reducing collisions with other structures during the installation of the bearing seat.

[0034] In one embodiment, a first pad 423 arranged in a vertical direction is installed on the vertical mounting surface 42, the bearing seat to be replaced abuts against the first pad 423, and the through hole 421 is located below the first pad 423.

[0035] For example, the first pad 423 is a composite pad with a cast nylon pad.

[0036] It should be noted that there are two first pads 423, and the two first pads 423 are arranged in a T-shape on the vertical mounting surface 42.

[0037] In this embodiment, a first pad 423 arranged in the vertical direction is installed on the vertical mounting surface 42, and the through hole 421 is located below the first pad 423. This allows the mop on the bearing seat to be installed to smoothly enter the guide sleeve 422 in the through hole 421, so that the bearing seat to be installed fits more tightly with the vertical mounting surface 42.

[0038] In one embodiment, the length and thickness of the first pad 423 are adapted to the bearing housing to be replaced.

[0039] In this embodiment, the thickness of the first pad 423 is adapted to the bearing housing to be installed, so that after the bearing housing to be installed is flipped, it can be firmly stabilized on the vertical mounting surface 42. During the flipping process, it can also reduce the collision between the bearing housing and the vertical mounting surface 42 and protect the bearing housing.

[0040] In one embodiment, a plurality of second pads 411 are installed on the horizontal mounting surface 41. The second pads 411 are arranged in the horizontal direction, and the plurality of second pads 411 are spaced apart on the horizontal mounting surface 41.

[0041] In this embodiment, the second pad 411 is spaced apart on the horizontal mounting surface 41, which can support the bearing housing before it is flipped, reduce the collision between the bearing housing and other components, and make the bearing housing more stably placed on the mounting mechanism 4.

[0042] In one embodiment, a second bearing housing 5 is also included, and the rotating shaft 2 is connected to the fixed frame 3 through the second bearing housing 5.

[0043] It should be noted that there are multiple second bearing seats 5, which are respectively set on both sides of the mounting frame. The second bearing seats 5 are mounted on the fixed frame 3 and cooperate with the rotating shaft 2.

[0044] In this embodiment, the rotating shaft 2 is connected to the fixed frame 3 through the second bearing seat 5, which allows the rotating shaft 2 to rotate relatively stably within the second bearing seat 5, thereby enabling the mounting mechanism 4 to rotate smoothly around the rotating shaft 2 and improving the stability of the equipment during operation.

[0045] In one embodiment, the drive mechanism is rotatably connected to the side of the mounting mechanism 4 near the vertical mounting surface 42. The drive mechanism is telescopically arranged in the vertical direction to drive the mounting mechanism 4 to rotate along the axis of rotation 2.

[0046] It should be noted that the back of the vertical mounting surface 42 on the mounting mechanism 4 is rotatably connected to the drive mechanism.

[0047] In this embodiment, the drive mechanism is rotatably connected to the side of the mounting mechanism 4 near the vertical mounting surface 42. The drive mechanism is telescopically arranged in the vertical direction. When the drive mechanism is driven, it can drive the mounting mechanism 4 to rotate along the axis of the rotating shaft 2, thereby flipping the bearing seat on the mounting mechanism 4 to a vertical angle. This structure is relatively simple, easy to use and maintain, low in cost, and very convenient.

[0048] In one embodiment, the system further includes a follower cover plate 6 and a connecting seat 7. One end of the follower cover plate 6 abuts against the connection side of the mounting mechanism 4 and the drive mechanism, and the connecting seat 7 is rotatably connected to the side of the follower cover plate 6 away from the mounting mechanism 4.

[0049] In this embodiment, the follower cover 6 abuts against the connection side of the mounting mechanism 4 and the drive mechanism. When the bearing seat is flipped, the follower cover 6 rotates with the mounting mechanism 4, which can reduce the situation where the guide sleeve 422 and the mop are suspended in the air, making the whole device more stable during operation.

[0050] In one embodiment, there are multiple connecting seats 7, which are spaced apart along the axis of rotation 2.

[0051] In this embodiment, multiple connecting seats 7 are spaced apart along the axis of rotation shaft 2, which makes the force on the follower cover 6 more uniform and allows it to smoothly follow the rotation and force of the mounting mechanism 4.

[0052] In one embodiment, a curved arm 8 is also included. One end of the curved arm 8 is connected to the bottom of the mounting mechanism 4, and the other end is connected to a pulley 81, which abuts against the bottom of the follower cover plate 6.

[0053] It should be noted that the curved arm 8 is connected to the bottom of the mounting mechanism 4 on the side near the horizontal mounting surface 41. The curved arm 8 is bent at a right angle and has a pulley 81 connected to its end. When the bearing seat is not flipped into a vertical state, this pulley 81 can cooperate with the bottom of the follower cover plate 6.

[0054] For example, the connection between the curved arm 8 and the mounting mechanism 4 is by welding.

[0055] In this embodiment, the curved arm 8 is located at the bottom of the mounting mechanism 4, and one end of it is connected to a pulley 81, which can provide support for the follower cover 6 before the bearing seat flips, so that the follower cover 6 can abut against the mounting mechanism 4 more stably.

[0056] The above technical solutions of this utility model are merely preferred embodiments and do not limit the patent scope of this utility model. All equivalent structural transformations made under the technical concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of this utility model.
