Abstract

The utility model relates to a decoiler drum floating support, which comprises a swinging arm, a connecting arm, a turning arm, a carrying roller and a swinging arm hydraulic cylinder, and is characterized in that the turning arm and a turning arm hydraulic cylinder form a connecting rod mechanism, and are respectively hinged with the swinging arm, and the carrying roller is respectively arranged on the turning arm and the swinging arm. The carrying roller is distributed in the range of 135-200 degrees in the circumferential direction on the right lower portion of a drum shaft. Compared with the prior art, the decoiler drum floating support has the advantages that elastic deformation of a decoiler drum shaft is effectively lowered because of adopting a reasonable structure, uncoiling tensile force variation is guaranteed within a regulated range, thereby improving the quality of a cold rolling strip steel.

Description

Reel of uncoiler floats and supports

Technical field

The utility model relates to a kind of unsteady support of reel of uncoiler that provides support power for the cold-strip steel reel of uncoiler when working.

Background technology

Before this, the unsteady support of cold-strip steel reel of uncoiler generally is divided into two kinds of forms according to the direction of its swing: a kind of is along the axial horizontal hunting of reel of uncoiler, holds or leave reel of uncoiler.Structure is that two groups of carrying rollers are fixedly mounted in the swing arm, and wherein one group of carrying roller is under reel of uncoiler cantilever end, and another group carrying roller is vertical with it, promotes swing arm campaign (see figure 3) by hydraulic cylinder; Another kind is along reel of uncoiler vertical oscillation radially, holds or leave reel of uncoiler.Structure is that three groups of carrying rollers are 60 degree angles each other and are fixedly mounted in the swing arm, and all below the horizontal center line of reel cantilever end, hydraulic cylinder promotes linkage and drives swing arm campaign (see figure 4) for three groups of carrying rollers.

The reel of uncoiler of these two kinds of structures, the unsteady support in the course of the work, because the variation in band coil of strip footpath brings the gravity change, reel changes with the strain that supports of floating thereupon, thereby causes the fluctuation that uncoiling tension distributes, and influences the cold-strip steel quality.

Summary of the invention

The purpose of this utility model provides the unsteady support of a kind of reel of uncoiler, solve in the uncoiler course of work, because the variation in band coil of strip footpath changes gravity, reel changes with the strain that supports of floating thereupon, and the uncoiling tension distribution fluctuates of bringing, thereby influence the problem of the quality of cold-strip steel.

The utility model is achieved through the following technical solutions:

Reel of uncoiler floats and supports, and comprises swing arm, linking arm, connecting lever, carrying roller, swing arm hydraulic cylinder, it is characterized in that, pivoted arm and boom hydraulic cylinder form linkage, and pivoted arm and boom hydraulic cylinder are hinged with swing arm respectively, and carrying roller is separately positioned in pivoted arm and the swing arm.

Described carrying roller distributes in 135～200 ° of scopes of spool shaft lower right circumferencial direction.

Compared with prior art, the beneficial effects of the utility model are: owing to adopted rational structure, reel of uncoiler axle strain effectively reduces, and guarantees that uncoiling tension changes within the scope of regulation, thereby improves the quality of cold-strip steel.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:

Seeing Fig. 1, is the unsteady support works status architecture schematic diagram of reel of uncoiler of the present utility model.

Seeing Fig. 2, is the unsteady off working state structural representation that supports of reel of uncoiler of the present utility model.

Swing arm 1, linking arm 2, connecting lever 3 and swing arm hydraulic cylinder 6 form linkage together, and pivoted arm 4 and boom hydraulic cylinder 7 also form linkage, and swing arm 1, connecting lever 3 and swing arm hydraulic cylinder 6 are all hinged with base 8, form strong supporting; Pivoted arm 4 and boom hydraulic cylinder 7 are hinged with swing arm 1 respectively, two groups of carrying rollers 5 directly are installed in the swing arm 1, another group carrying roller 1 is installed on the pivoted arm 4, three groups of carrying rollers distribute in 135～200 ° of scopes of spool shaft lower right circumferencial direction, and carrying roller 5, pivoted arm 4 and boom hydraulic cylinder 7 can be followed swing arm 1 and be swung up and down.Coil of strip 10 is transported to the uncoiler position by the coil of strip dolly and is enclosed within on the spool shaft 9, and swing arm hydraulic cylinder 6 cylinder bars stretch out the work of drivening rod mechanism, put the operating position in the swing arm 1, and two groups of carrying rollers 5 installing in the swing arm 1 put in place and hold spool shaft 9 cantilever ends; At this moment, boom hydraulic cylinder 7 stretches out, and boosts pivoted arm 4, makes the carrying roller of installing on the pivoted arm 45 push down spool shaft 9 cantilever ends, and reel floats to support and is in the operating position, and spool shaft 9 is rotated the uncoiler uncoiling.After uncoiling finished, boom hydraulic cylinder 7 and swing arm hydraulic cylinder 6 successively were withdrawn into raw bits, and unsteady support falls, and is in off-position, finishes an action cycle.

Claims

1. reel of uncoiler floats and supports, comprise swing arm, linking arm, connecting lever, carrying roller, swing arm hydraulic cylinder, it is characterized in that pivoted arm and boom hydraulic cylinder form linkage, pivoted arm and boom hydraulic cylinder are hinged with swing arm respectively, and carrying roller is separately positioned in pivoted arm and the swing arm.

2. reel of uncoiler according to claim 1 floats and supports, and described carrying roller distributes in 135～200 ° of scopes of spool shaft lower right circumferencial direction.
