Description

Technical Field

[0001] The present application belongs to the technical field of cold rolling mills, and more specifically, to a mobile platform for quick-changing a roll assembly. Background Art

[0002] The cold rolling mill is a metal seamless pipe processing equipment widely used in industrial production. It is mainly used to roll metal billets into finished pipes of required sizes. The roll assembly is an important equipment in the cold rolling mill. When rolling pipes of different sizes or the roll assembly is too severely worn, the roll assembly needs to be replaced. In modern industrial production lines, the rapid replacement of the roll assembly is crucial to improving production efficiency and reducing downtime. The traditional roll replacement method usually involves complex operating procedures and long-term manual intervention, which not only affects production efficiency, but also increases safety risks during operation. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a mobile platform for quick-changing a roller assembly, so as to solve the technical problem of low replacement efficiency of the roller assembly existing in the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is: to provide a roller assembly quick-change mobile platform, including:

[0005] A bracket, used for mounting on a cold-rolled tube machine body;

[0006] A roller assembly seat, mounted on the bracket and used for detachable connection with different roller assemblies;

[0007] A transfer assembly, comprising a first track and a moving trolley slidably connected to the first track, a second track perpendicular to the first track and extending toward the roll assembly seat is arranged on the side of the moving trolley away from the first track, the second track has at least two groups spaced apart along the extension direction of the first track, and the transfer assembly further comprises a loading platform slidably connected to the second track and used to carry the roll assembly;

[0008] The traction assembly comprises a traction rod connected to the bracket and parallel to the second track. The traction rod is used for reciprocating along its own axis and one end of the traction rod close to the loading platform has a connection structure adapted to the roller assembly.

[0009] Optionally, a relay slideway is provided between the transfer assembly and the roller assembly seat, which is used to be connected to the cold-rolled tube body and connected to the second track.

[0010] Optionally, each group of the second rails is provided with at least two rails and all of them are used for sliding connection with the loading platform.

[0011] Optionally, at least two of the first tracks are arranged in parallel and at intervals.

[0012] Optionally, a push-pull handle is provided on the loading platform and / or the moving trolley.

[0013] Optionally, the traction assembly further comprises a motor drivingly connected to the traction rod and used to drive the traction rod;

[0014] The motor is mounted on the bracket.

[0015] Optionally, the traction rod is a threaded rod, and the connecting structure is a connecting flange provided at the front end of the traction rod for connecting to the roller assembly.

[0016] Optionally, the bracket is connected with a lifting lug for facilitating lifting of the bracket.

[0017] The beneficial effect of the roller assembly quick-change mobile platform provided by the present application is that: compared with the prior art, the transfer assembly in the present application includes a mobile trolley that can move on the first track and a loading platform that is arranged on the mobile trolley and can move along the second track. Since the second track extends toward the roller mounting seat and has at least two groups distributed along the direction of the first guide rail, in the process of replacing the roller assembly, the new roller assembly can be placed on one of the loading platforms in advance, and then the old roller assembly is detached from the roller assembly seat and the old roller assembly is driven to slide to another loading platform by a traction rod. At this time, the traction rod and the old roller assembly can be separated and the trolley can be moved on the first track to connect the traction rod to the new roller assembly. Then, the traction rod can be moved in the opposite direction to gradually move the new roller assembly toward the roller assembly seat by the traction rod. Finally, the roller assembly is connected to the roller assembly seat to achieve rapid replacement of the roller assembly, which has a high replacement efficiency far superior to the prior art.
