Technical Field
The utility model relates to a steel rolling technical field especially relates to an interim roll-changing device that is used for roll-changing operation when roll-changing dolly trouble.
Background
With the increasing requirements on the thickness, the shape and the surface quality of the plate, the working rolls must be replaced frequently in the rolling process, so that the existing rolling mill is generally provided with a quick roll replacing device; the rolling mill is transported in the rolling mill housing by means of travelling wheels mounted on the work roll bearing blocks, through fixed or floating rails traversing the rolling mill, while the new and old work rolls are transported outside the rolling mill by means of roll change trolleys. The roller changing trolley used at present can be divided into a push-pull type electric roller changing trolley and a hydraulic type roller changing trolley, the roller changing trolley travels on a preset track, the roller changing trolley stays at a roller changing position during roller changing, a new working roller and a pulled-out old working roller are both arranged on a transverse moving platform of the roller changing trolley, the new working roller is re-arranged on a rolling mill after transverse moving, and then the old working roller is conveyed to a grinding roller room by the roller changing trolley for maintenance treatment. When the roller changing trolley breaks down, the roller changing trolley cannot be off-line for maintenance due to the cable or the hydraulic pipeline, so that the roller changing trolley only can be stopped for maintenance, and the production of a rolling line is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a roll change method when roll change dolly trouble adopts interim roll change device to realize roll change operation when the roll change dolly breaks down, has guaranteed the normal production of rolling line.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a temporary roll changing device comprises a base, hook locking grooves, a rail, a lifting lug and a warning lamp, wherein the rail is arranged at the top of the base, and 2 hook locking grooves are formed in one end of the base; lifting lugs are respectively arranged on two sides of the base; warning lamps are respectively arranged around the base.
The track is arranged along the drawing direction of the working roll and is matched with the travelling wheels at the bottom of the bearing seat of the working roll.
And the hook locking groove is matched with the rolling mill trolley hook to realize the locking and fixing of the temporary roll changing device on one side of the rolling mill trolley.
The track is connected with the track in the rolling mill platform truck at the base one end that is equipped with the couple locking groove outwards extends, is equipped with the backstop piece in the track outside of the other end.
Compared with the prior art, the beneficial effects of the utility model are that:
1) when the roller changing trolley breaks down, the temporary roller changing device is adopted to realize the roller changing operation, so that the normal production of the rolling line is ensured;
2) the temporary roll changing device is simple in structure, convenient to operate and low in manufacturing cost.

In the figure: 1. base 2, track 3, couple locking groove 4, lug 5, warning light 6, working roll 7, backstop piece
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
the utility model relates to a temporary roll changing device, which consists of a base 1, a hook locking groove 3, a track 2, a lifting lug 4 and a warning light 5, wherein the track 2 is arranged at the top of the base 1, and one end of the base 1 is provided with 2 hook locking grooves 3; lifting lugs 4 are respectively arranged on two sides of the base 1; warning lights 5 are respectively arranged around the base 1.
The track 2 is arranged along the drawing-out direction of the working roll 6 and is matched with the walking wheel at the bottom of the bearing seat of the working roll.
And the hook locking groove 3 is matched with a rolling mill trolley hook to realize the locking and fixing of the temporary roll changing device on one side of the rolling mill trolley.
One end of the base 1 provided with the hook locking groove 3 of the track 2 extends outwards to be connected with the track in the rolling mill trolley, and a stop block 7 is arranged on the outer side of the track at the other end.
Use a interim roll change device replaces roll change dolly to accomplish the step of roll change operation as follows:
1) when a certain roll changing trolley breaks down, the roll changing trolley is moved away from a roll changing position to carry out online maintenance treatment, and a new working roll is transported to a rolling line from a grinding roll room by a ground cross-bar;
2) as shown in fig. 1, the temporary roll-changing device is composed of a base 1, a hook locking groove 3, a track 2, a lifting lug 4 and a warning light 5, wherein the track 2 is arranged at the top of the base 1 and is used for moving a working roll 6 in cooperation with a travelling wheel of a bearing seat of the working roll; one end of the base 1 is provided with a hook locking groove 3 which is used for matching, locking and fixing with a rolling mill trolley hook; lifting lugs 4 are respectively arranged on two sides of the base 1 and used for lifting the temporary roll changing device; warning lamps 5 are arranged on the periphery of the base 1 and used for warning during lifting;
3) hanging a steel rope of a crane on a lifting lug 4 of the temporary roll changing device, lifting the temporary roll changing device to a roll changing position, and locking and fixing the temporary roll changing device by matching a hook on a rolling mill trolley with a hook locking groove 3 so as to suspend the temporary roll changing device beside a rolling mill roller way;
4) the method comprises the following steps of operating according to a conventional roll changing step, manually pushing an old working roll to a track 2 of a temporary roll changing device when the old working roll is pulled out, then hanging a crane steel rope on roll shafts at two ends of the old working roll, and lifting and transporting the old working roll to a grinding roll room for treatment;
5) hanging a new working roll on a track 2 of the temporary roll changing device, and manually installing the new working roll according to a roll changing operation flow;
6) after the new working roll is installed, the hook on the rolling mill trolley is separated from the hook locking groove 3, and then the temporary roll changing device is lifted away from the roll changing position, so that normal production can be recovered.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
