Description

Loop swing door rotates bearing structure

Technical Field

The utility model relates to a steel rolling production technical field especially relates to a loop swing door rotation support structure.

Background

The loop is a common device in the field of steel rolling production, and is used for storing and releasing strip steel, so that the stable operation of a process section can be ensured in the process of welding a strip head and a strip tail by the strip steel, in the process of storing the strip steel by the loop, the strip steel is longer and heavier, the loop is supported by a swing door in a supporting mode, the swing door of the loop comprises a swing door upright post, a supporting arm fixed on the swing door upright post, a rubber roller arranged on the supporting arm and other structures, the middle part of the rubber roller is in a suspended state because the rubber roller generally adopts a slender rubber roller, and the damage of rotating structures at two ends of the rubber roller is easy to occur because the rubber roller needs to frequently bear the weight of the strip steel and the impact caused by the movement of the strip steel in the working process, so that the normal.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to avoid prior art's weak point, provide a loop swing door rotation bearing structure to effectively solve the weak point that exists among the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a loop swing door rotates bearing structure, includes the swing door stand, the fixed trailing arm that is provided with on the swing door stand is provided with the mounting groove that has the upper shed on the trailing arm, and the mounting groove internal rotation is provided with the rubber roll, and the upside of rubber roll is higher than the upper surface of trailing arm, the bottom bilateral symmetry of rubber roll is provided with the riding wheel, and the riding wheel passes through the rotatable setting of mounting bracket in the mounting groove.

Further, the riding wheel is a bearing.

Furthermore, the riding wheel is evenly provided with a plurality of positions at intervals along the axial direction of the rubber roller.

The above technical scheme of the utility model following beneficial effect has: the utility model discloses a bottom at the rubber roll sets up the riding wheel, can play fine rotation supporting role to long and thin rubber roll middle part, and then can make the fine important and belted steel's of bearing of rubber roll impact, reduced the maintenance number of times, improved the productivity.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-2, a loop swing door rotation support structure described in this embodiment, including swing door stand 1, the last fixed trailing arm 2 that is provided with of swing door stand 1, the last mounting groove 3 that has the upper shed that is provided with of trailing arm 2, the internal rotation of mounting groove 3 is provided with rubber roll 4, the upside of rubber roll 4 is higher than the upper surface of trailing arm 2, above structure is prior art, regarding the concrete structure of loop swing door, can refer to the utility model patent specification that publication number is "CN 205908176U", in order to improve the behavior of rubber roll 4, do the improvement of following structure:

riding wheels 5 are symmetrically arranged on two sides of the bottom of the rubber roller 4, and the riding wheels 5 are rotatably arranged in the mounting groove 3 through a mounting frame 6.

In the present embodiment, the idler 5 is a bearing.

The riding wheels 5 are evenly arranged at a plurality of positions along the axial direction of the rubber roller 4 at intervals.

The utility model discloses a bottom at the rubber roll sets up the riding wheel, can play fine rotation supporting role to long and thin rubber roll middle part, and then can make the fine important and belted steel's of bearing of rubber roll impact, reduced the maintenance number of times, improved the productivity.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
