Switching device and switching system for descaling roll replacement operation vehicle

Abstract

The invention relates to a switching device and switching system for a descaling roll replacement operation vehicle. The switching device comprises an operation vehicle track fixedly arranged and a base intermittently running back and forth along the operation vehicle track. Two guide roll seats loaded with roll replacement bearing devices are mounted on the upper end surface of the base side by side. Guide roll seat driving mechanisms are connected to the guide roll seats. The guide roll seats move under the action of the guide roll seat driving mechanisms. The moving direction of the guide roll seats is perpendicular to the moving direction of the base. The distance between the guide roll seats and the base is controlled to be one-sixth to one third of the length of the guide roll seats.According to the switching device and the switching system, the guide roll seats move along with the base, so that the corresponding guide roll seats are switched to the positions needing roll replacing or roll connection, and each guide roll seat can move forwards or backwards under the action of the corresponding guide roll seat driving mechanism, so that the corresponding guide roll seats getclose to or far away from roll replacement inlets of a derusting machine; and the guide roll seats move outwards relative to the base only a certain distance, thereby being not disengaged from the base, and the roll replacement bearing devices cannot be overturned.

Description

technical field [0001] The invention belongs to the technical field of descaling roller replacement of derusting machines, and in particular relates to a switching device and a switching system of a descaling roller changing operation vehicle. Background technique [0002] It often takes a period of time before the steel plate is produced and actually used. During this period, due to the properties of the steel plate itself, the surface of the steel plate will be rusted, which will affect the actual use. Rust treatment. [0003] At present, the method for removing rust on the surface of steel plates is generally pickling and rust removal. The principle is to use the acid in the pickling solution to chemically react with the metal oxide to dissolve the metal oxide and remove the rust and dirt on the steel surface. However, after the steel plate is pickled and derusted, it must be cleaned with a large amount of water and passivated. The large amount of waste water, waste aci...

Problems solved by technology

[0004] Of course, there are also some physical rust removal methods. At present, the rust removal and polishing process on the steel plate surface in this technical field uses a disc brush or an abrasive belt rust removal mechanical device. Poor, the efficiency of rust removal is low and the surface of the steel plate cannot be fully cleaned; on the other hand, when the disc brush or the abrasive belt needs to be replaced due to wear and tear, it often requires manual operation for a long time, which is time-consuming and laborious

[0005] The scale-breaking roller is now used to peel off or loosen the iron oxide scale on the strip steel billet to achieve the effect of rust removal. The scale-breaking roller is formed with nylon or diamond grinding brush sticks along the circumference. The middle grinding brush roller will gradually wear out, therefore, it is necessary to change the roller operation, which requires manual assistance before, which is very time-consuming, laborious and inefficient

[0006] The special design involves a roll changing operation vehicle, which can enter the derusting machine to lift the old rolls that have been removed and move them out of the derusting machine, but if new rolls are installed, the old rolls need to be unloaded Next, it is troublesome to place new rolls on the roll changing vehicle, which reduces the efficiency
