Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. 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.

A quick-change auxiliary device of a rod mill is shown in figures 1-4 and comprises a bottom plate 1, a sliding plate 2 and a hydraulic rod 12, wherein the sliding plate 2 is rotatably connected to the side surface of the bottom plate 1 and is convenient to store, at least two supports 11 are arranged on the bottom plate 1, the hydraulic rod 12 is arranged on the supports 11, the supports 11 support the hydraulic rod 12, the hydraulic rod 12 faces the sliding plate 2, protection plates 21 are arranged on two sides of the sliding plate 2, the rod mill is placed on the sliding plate 2, and when the hydraulic rod 12 pushes the rod mill, the protection plates 21 play a role of enclosure, so that the rod mill is prevented from sliding out of the sliding plate 2, and the safety is improved;

the sliding plate 2 is provided with a plurality of horizontal mounting grooves, the mounting grooves are internally provided with the rotating rollers 22, the side surfaces of the rotating rollers 22 are 3-6 mm higher than the upper surface of the sliding plate 2, the rod rolling mill can smoothly slide onto the rotating rollers 22 and move on the rotating rollers 22, and the rotating rollers 22 enable the rod rolling mill to smoothly slide.

And a hydraulic system is arranged in match with the hydraulic rod 12 and controls and is connected with the hydraulic rod 12, and the hydraulic system is in the prior art (comprising an oil pump, an oil tank, an oil pipe and the like) and enables the hydraulic rod 12 to stretch and retract.

The upper surface of the slide plate 2 is coated with lubricating oil, and the surface of the rotating roller 22 is also coated with lubricating oil, so that the lubricating oil reduces the friction force of the rod rolling mill when the rod rolling mill moves on the slide plate 2, and the rod rolling mill moves smoothly.
