Description
Technical field
The utility model relates to jockey pulley maintenance equipment technology field, particularly relates to a kind of roller detaching device for coupling.
Background technology
In flat cold-rolled sheet production technology, jockey pulley is equipment very important in cold rolled sheet production process, and it is distributed in the key position of production line, in different regions for distinct device provides tension force, to meet the tensile requirements that whole production line is produced.
The each shop production line in cold rolling portion is all furnished with the jockey pulley of varying number, the base roller of jockey pulley is made up of welded steel structure base plate and support, bearing is arranged in detachable bearing block, to keep centering during roll change, each roller is driven separately by motor and gear reduction unit, connected, roller diameter 1065mm between reductor and roller by shaft coupling, the long 2000mm of the body of roll, surface coverage polyurethane.
Because roll surface materials is polyurethane, in the production process of large load, because raw material version type is bad or raw material rippled edge is comparatively large, huge injury is produced to roller polyurethane surface; Or caused by the performance of polyurethane own, in use, once service time is long, just there will be the phenomenon of surface aging, directly affect its tension value that can produce; Or because a variety of causes causes roller to damage, must change roller when there is above-mentioned situation.
Owing to being connected with shaft coupling between roller with reductor, the strand drilling of shaft coupling coordinates strict, shaft coupling on old roller spindle nose must be pulled down, changing is installed on new roller spindle nose, tear shaft coupling open all to need aluminum steel to be entangled in and connect high-power transformer after on shaft coupling and carry out " electricity moves back " before at every turn, this method cost is high, and need to prepare in advance, contact with corresponding unit, once occur that burst accident can not prepare in advance, repairing progress will be had a strong impact on, cause larger indirect economic loss, therefore, quick-replaceable roller shaft coupling becomes a problem demanding prompt solution.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of roller detaching device for coupling, use the jack be arranged in casing as power source, and by means of clamp, the shaft coupling being arranged on roller axle end is stuck in casing, outwards roller axle is pushed up with the push rod of jack, realize the dismounting of shaft coupling, easy to use, coordinate without the need to other unit, improve first-aid repair efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of roller detaching device for coupling, the casing comprising upper shed and the jack be fixedly installed in casing, the end plate of described casing one end is provided with U-shaped breach, clamp is provided with in described casing, described clamp is rectangular plate-like structure, and the width of described rectangular plate-like structure is identical with box inside width, has the U-shaped breach establishing roller axle for card in the middle part of described rectangular plate-like structure.
Described casing internal fixtion is provided with two pieces of gripper shoes for support jack, and described two pieces of gripper shoes are evenly arranged along casing length direction, and described jack is fastened in draw-in groove that gripper shoe is arranged, and described jack tail end contacts with cabinet wall.
The beneficial effect adopting technique scheme to produce is: by using the jack be arranged in casing as power source, coordinate with the clamp be arranged in casing, in use, roller axle is fastened in the U-shaped breach on clamp, guarantee that shaft coupling is positioned at casing, the push rod of roller axle and jack is oppositely arranged simultaneously, roller rear use jack pushing tow roller axle in place, clamp limits the position of shaft coupling, under the ejection effect of jack, roller axle is outwards exited, realize the dismounting of shaft coupling, simultaneously in unloading process, for the ease of dismounting, flame or electrically heated mode can be adopted to heat shaft coupling, improve removal efficiency, in whole unloading process, coordinate without the need to other unit, workshop hydraulic system is only utilized to realize, and this apparatus structure is simple, easy to use, greatly can improve removal efficiency, reduce costs.
