Abstract
The invention discloses an automatic unhooking device of supporting roll changing of a cold mill unit, belongs to a cold mill unit device, and particularly designs the automatic unhooking device of the supporting roll changing of the cold mill unit. The automatic unhooking device of the supporting roll changing of the cold mill unit comprises a roll changing device, an unhooking device and a supporting roll hook. The automatic decoupling device of the supporting roll changing of the cold mill unit is characterized in that the roll changing device and the supporting roll hook are connected in a lap joint mode, and the unhooking device is arranged on the side lower portion of the roll changing device. The automatic unhooking device of the supporting roll changing of the cold mill unit has the advantages of being novel in structure, convenient to process, and convenient to use, and the labor strength is relieved, working efficiency is improved and safe accidents are avoided, so the novel automatic unhooking device of the supporting roll changing of the cold mill unit integrates economy and practicability.
Description
Technical field
Cold rolling unit backup roll change automatic decoupling device of the present invention belongs to cold rolling unit equipment, a kind of cold rolling unit backup roll change decoupling device of specific design.
Background technology
Present domestic self-developing design, the cold rolling unit back-up roll extractor of making, the roll change process is automatic hasp, manually decoupling device.Be after roll change cylinder hook overlaps automatically, by manually with ripping bar, hook being sticked up, to realize the separation of hook, go operation under this process need workman in melt pit, strengthened roll changing time and operation inconvenience, have potential safety hazard.For existing problem in above-mentioned prior art, a kind of novel cold rolling unit backup roll change automatic decoupling device of research and design, in prior art, existing problem is very necessary thereby overcome.
Summary of the invention
In view of existing problem in above-mentioned prior art, the present invention is intended to avoid the shortcoming and defect that exists in above-mentioned roll change form, compact conformation is provided, can realize automation control, simply small and exquisite, good looking appearance, a kind of cold rolling unit backup roll change automatic decoupling device is very easily used in reliable and operation.Exist in prior art in order to solve: labor strength is large, efficient is low, have the problems such as potential safety hazard.
Technical solution of the present invention is achieved in that
Cold rolling unit backup roll change automatic decoupling device of the present invention is comprised of changing rig, decoupling device and backing roll hook; It is characterized in that described changing rig and backing roll hook overlap mutually; Be loaded on the side-lower of changing rig at decoupling device.
Changing rig of the present invention comprises roll change cylinder, roll change hook, bearing pin, roller bracket and support roller; The roll change hook is loaded on the front end of roll change cylinder by bearing pin, be connected to roller bracket at a side rigid connecting of roll change hook, and tugboat is housed on roller bracket; The roll change hook overlaps mutually with the backing roll hook.
Decoupling device of the present invention comprises decoupling device cylinder, decoupling device pivoted arm, pivoted arm support and decoupling device cylinder frame; The decoupling device cylinder is loaded on decoupling device cylinder frame, and lever front end and the decoupling device pivoted arm lower end of decoupling device cylinder are hinged, and the middle part of decoupling device pivoted arm is loaded on the pivoted arm support by bearing pin; The front end of decoupling device pivoted arm is positioned at the bottom of support roller; The decoupling device pivoted arm can decoupling device cylinder lever promotion under the rotation take bearing pin as fulcrum, lift on the front end of decoupling device pivoted arm, promote roller rack and move up, drive the roll change hook and lift with the backing roll hook and separate, realize decoupling device.
At milling train fore side installing backup roll change automatic decoupling device, when backup roll change, utilize this device to realize that the roll change hook separates automatically with backing roll.When the backup roll change state, the roll change cylinder promotes roll change hook and backing roll hook overlap joint, and the roll change cylinder is retracted, and pulls out backing roll.Need to open the roll change hook this moment, and backing roll is hung away.The decoupling device cylinder starts, and stretches out the cylinder bar and promotes decoupling device pivoted arm bottom forward, and the bearing pin that the decoupling device pivoted arm rotates on arm support rotates, and decoupling device pivoted arm top is lifted support roller is held up.Support roller is rigidly connected by tugboat support and bearing pin and roll change hook.Support roller lifts drive roll change hook and lifts, and the roll change hook separates with the backing roll hook, and automatic decoupling is complete.
Advantage of the present invention is apparent, is mainly manifested in:
1, use of the present invention has reduced workman's labour intensity, has improved operating efficiency;
2, use of the present invention has been avoided manually closely operation of workman, the generation of having stopped security incident.
The present invention have novel structure, processing easy, easy to use, reduced labour intensity, improved operating efficiency, avoided the advantages such as generation of security incident, it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
