Description
Technical field
The utility model relates to for the quality for guaranteeing roll chock replacement, subtract simultaneously in the metal plates and strips operation of rolling
The difficulty replaced less improves replacement efficiency, realizes that a kind of device of roll chock replacement, specially bearing block quick-replaceable fill
It sets.
Background technique
In metal plates and strips production process, the bearing block replacement of roll belongs to one kind and frequently changes production work, all
Milling equipment production process in be all a kind of replacement process repeatedly.Under normal circumstances, the bearing block replacement of roll needs two
Individual's cooperation overhead traveling crane is completed jointly, and roll will be laid flat in bracket when replacement, and a people will be on roll using suspender belt using overhead traveling crane
Bearing block is sling, and the center parallel with roll, another people pushes out bearing block, and in the process, overhead traveling crane need to be with axis
It holds the movement of seat and moves, and must assure that bearing block cannot tilt, otherwise bearing block will be unable to disassemble from roll；
Two people's work compounds are needed during this, and are cooperated and be also required to the tacit disassembly that can smoothly realize bearing block；Assembly
Process is also such.In the lesser situation of roll, bearing block is light-weight, and disassembly or installation are relatively easy, and general milling train
Roll, especially support roller are all bigger, and for weight at several tons or more, bearing block weight is also relatively large, and Manual-pushing is leaned on when replacement
It is even more extremely difficult.Replacement roll chock is normal required, such roll change process, that is, time-consuming that milling equipment operates, and takes people
Power influences to change production efficiency on production line, and seriously affects the service life of bearing.
Summary of the invention
In order to quick-replaceable bearing block in process of production, the utility model provides one kind quickly, accurately, effectively,
And reduce the bearing block quick replacement device of labor intensity.
The utility model adopts the following technical scheme that realization: bearing block quick replacement device, including places roll
Roller bracket and be all located at the bearing block base and bearing block movable support of roller bracket two sides, be fixed on bearing block base
Motor and worm type of reduction gearing positioned at bearing block base two sides, the worm gear of the worm type of reduction gearing of motor and wherein side
Connection, the side worm gear also pass through the worm gear connection of the worm type of reduction gearing of transmission shaft and shaft coupling and the other side, worm and gear
The worm screw of retarder all connect with lead screw, and lead screw upper end is connect with bearing block movable support, is arranged on bearing block movable support small
Vehicle is provided with the sliding block separated in two sides in small roof panels.
When work, roll is placed on the roller bracket of roll, and fixed motor passes through worm and gear on bearing block base
The transmission of retarder realizes lead screw and moves up and down, and the bearing block movable support to link together with lead screw is driven to move up and down,
The height of bearing block is adjusted, to realize the bearing block replacement of different size roll；It, will be small on movable support when dismantling bearing block
Vehicle moves to below bearing block, and bearing block is held in adjustment bearing block movable support rising, and the sliding block of two sides on trolley is moved inward
To blocking on the inside of bearing block, trolley is pulled out, by bearing block by splitting out on roll；Equally, when installing bearing block, by bearing block
It is placed on trolley, the height of adjustment bearing block movable support, in sustained height, is pushed away to bearing block center line and roller central line
Dynamic trolley, bearing block is mounted on roll.Holding is horizontal when in order to guarantee that bearing block movable support adjustment height moves up and down,
It runs smoothly, bearing block movable support passes through transmission shaft and shaft coupling by two sets of feed screw apparatus support transmissions, two sets of transmission devices
Connection can individually adjust the height of side by disconnection shaft coupling when bearing block movable support levelness does not reach requirement,
To guarantee roll and bearing block axis in the same horizontal line.To improve working efficiency, two sets of bearings are equipped in the two sides of roll
Seat replacement system, can be achieved at the same time two side shaft holders and synchronizes and remove and install.
Linear guide is arranged in the two sides of above-mentioned bearing block quick replacement device, roller bracket, bearing block movable support
One side end is stuck in the side linear guide.Bearing block movable support can be realized up and down along the linear guide of roller bracket side
Movement.
Above-mentioned bearing block quick replacement device is provided with dovetail groove in small roof panels, and sliding block is stuck in dovetail groove.
Above-mentioned bearing block quick replacement device is connected with nut on worm type of reduction gearing, and nut covers on lead screw, should
Nut makes lead screw lifting smooth, does not shake.
The utility model structure is simple, easy to operate, and compared with former traditional substitute mode, replacement process does not need overhead traveling crane and matches
It closes, is also not required to two people compounding practice simultaneously, the quick-replaceable of bearing block can be completed in an operator, and substantially reduces
Working strength.
