Abstract

The utility model discloses a retractable roll system roll changing device, which comprises a trolley, trolley slides for the trolley to move on, a trolley hydraulic cylinder for driving the trolley to move, two roll racks parallel to each other and arranged on the trolley, and a roll hydraulic cylinder for driving rolls to move. The inner side of the each roll rack is provided with roll tracks in corresponding same quantity, and the rolls are disposed into the roll tracks. The retractable roll system roll changing device can realize simultaneous change of a plurality of the rolls in a short period of time, and has high work efficiency.

Description

The open-close type roller is a changing rig

Technical field

The changing rig of the relevant a kind of operation roll of mill of the utility model, be meant especially a kind ofly be used for four, the open-close type roller of six-high cluster mill roller system is changing rig.

Background technology

The dismounting rolling mill roll is a key link during metallurgical Metallurgical Enterprise is produced, its objective is and to keep in repair or to reinstall new roll through the roll that uses and may wear to a certain degree on the production line, at present, hydraulic pressure or electric screw down gear are extensively adopted in replacing for working roll, the bottom adds the roller set location mode of backing plate, electric screw down gear was mentioned when roll was changed, the backing plate of bottom is by artificial extraction, the roll that is arranged in parallel up and down is separated from each other, roller system is in the roll change state, the position of the roll of optionally changing then, be used for the replacing of this roll by the corresponding roll change shelf of a dead lift, if change a plurality of rolls simultaneously, make up with regard to the continuous corresponding roll change shelf of a dead lift, so that change the roll that is in the differing heights position, therefore existing replacing roll mode length consuming time, labour intensity is big, cause production efficiency low, and existing roll replacing method place adaptability is very low, floor space is big.

The utility model content

In view of this, the main purpose of the present utility model open-close type roller little and that adapt to complicated workshop condition that is to provide a kind of and can changes roll and high efficiency fast, takes up room is a changing rig.

For achieving the above object, it is changing rig that the utility model provides a kind of open-close type roller, it includes car body, the car body slide rail of the body of buying car in installments walking, be used to drive the car body walking the car body hydraulic cylinder, be located at two the roll support bodys that are parallel to each other on the car body and be used to drive the roll hydraulic cylinder that roll moves, the inboard of each roll support body is equipped with the roll track of corresponding equal number, and roll is positioned in the roll track.

The car body upper surface also is fixed with cross sliding rail, and the roll support body is arranged on the cross sliding rail, and the cross sliding rail both sides respectively are provided with and can drive the traversing hydraulic cylinder of roll support body along the cross sliding rail move left and right.

Each the roll hydraulic cylinder that drives roll is fixed together by support.

By open-close type roller of the present utility model is that changing rig can realize at short notice that a plurality of rolls change simultaneously, high efficiency, and to be that changing rig takes up room little for open-close type roller of the present utility model simultaneously, and adapt to complicated workshop condition.

Fig. 2 is the right view of changing rig for the utility model open-close type roller.

The specific embodiment

For ease of structure of the present utility model and the effect that reaches are had further understanding, the preferred embodiment that develops simultaneously of existing conjunction with figs. is described in detail as follows.

As Fig. 1 and shown in Figure 2, the utility model open-close type roller is that changing rig includes car body 1, the car body slide rail 2 of the body of buying car in installments walking, be used to drive the car body hydraulic cylinder 3 of car body walking, be located at two the roll support bodys 4 that are parallel to each other on the car body and be used to drive the roll hydraulic cylinder 5 that roll moves, changing rig of the present utility model can be used for four-high mill roller system, also can be used for six-high cluster mill roller system, open-close type roller in the present embodiment is that changing rig is used for six-high cluster mill roller system, the inboard of each roll support body 4 is equipped with corresponding four roll tracks 40, roll track 40 is used to place roll and roll is slided therein, the roll of placing in the roll track 40 is respectively central roll from top to bottom, last work roll, following work roll reaches central roll down, the roll hydraulic cylinder 5 that is used to drive above-mentioned roll is respectively the central roll hydraulic cylinder from top to bottom, last work roll hydraulic cylinder, following work roll hydraulic cylinder reaches central roll hydraulic cylinder down, and roll hydraulic cylinder 5 from top to bottom is fixed together by support 50.Car body hydraulic cylinder 3 is fixing by cylinder support 30.

Car body 1 upper surface in the utility model also is fixed with cross sliding rail 10, roll support body 4 is arranged on the cross sliding rail 10, cross sliding rail 10 both sides respectively are provided with traversing hydraulic cylinder 11, and traversing hydraulic cylinder 11 can drive roll support body 4 along cross sliding rail 10 move left and right, as shown in Figure 2.

The utility model open-close type roller is that changing rig is when implementing, car body hydraulic cylinder 3 drives car body 1 front and back on car body slide rail 2 and moves, the roll that car body 1 drives the roll support body 4 on it will be needed to change is pulled out from milling train, traversing hydraulic cylinder 11 drives roll support body 4 move left and right on cross sliding rail 10, making has enough space to enter for the staff wherein to keep in repair and change roll between two roll support bodys 4, it is mobile that roll hydraulic cylinder 5 drives the roll front and back on roll track 40 that will change simultaneously, old roll is extracted out and changed new roll, by the driving of traversing hydraulic cylinder 11 and car body hydraulic cylinder 3 new roll is inserted in the milling train again.Open-close type roller of the present utility model is that changing rig can realize at short notice that a plurality of rolls change high efficiency simultaneously.

The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
