Abstract
The utility model relates to a device for extracting a broken roller in a rolling mill. The device for extracting the broken roller in the rolling mill comprises a pothook portion and a limiting assembly, wherein the pothook portion is arranged at an end portion of a car body and is used for being connected with a power device, and the limiting assembly is arranged at the other end portion of the car body and is used for dragging a broken rocker bearing box in a hooking mode. The limiting assembly adopted by the device can fix the bearing box, the stable bearing box will not make a working roller swing, and therefore a supporting roller will not be damaged when the working roller is manufactured.
Description
Technical field
The utility model relates to a kind of for the device that extracts the milling train roll breakage.
Background technology
Milling train is in the process of rolled steel, because selection and the heat treatment of roll is improper, and roll breakage accident all may take place reason such as casting flaw, and the easy normally working roll of roll breakage on the milling train.In the prior art, the working roll of changing fracture adopts the fixing mode of steel wire rope binding that roll breakage is extracted out usually, owing to need enter in the frame with steel wire rope binding steady job roller, extract out with the device of slinging again after being fixed, by one in backing roll is installed below working roll, spacing between the two is less, working roll in extraction very easily produces swing, thereby easily make its collision backing roll, cause the roll surface of backing roll to damage, simultaneously, adopt steel wire rope binding working roll not only to waste time and energy, and the processing time is longer, thereby has seriously influenced the efficient of producing; Topmost problem is that the mode of this kind extraction working roll can't be guaranteed operating personnel's safety, so changing working roll extraction mode is vital problem.
In order to address the above problem, China Patent No. is " 200820014709.7 ", name is called " roll breakage withdrawing device " and has proposed a solution, and this utility model comprises pawls car body, wheel and pull bar, the car body front end is provided with pawls, and wheel is installed in the car body lower end, and wheel is installed on the work roll changing track, the car body rear end is provided with pull bar, and pull bar is connected with roll change buggy.Though this device has reduced labor intensity of operating personnel, when being taken out, roll breakage is difficult for backing roll is damaged, but extract working roll process in, except preventing that working roll and backing roll from colliding, also need disconnected working roll bearing at end case is fixed, otherwise bearing housing can be damaged, and this kind device is placed on bearing housing on the pull bar, and by power set pulling pull bar working roll is taken out, the mode of this extraction working roll easily causes bearing housing to damage.
Summary of the invention
The purpose of this utility model provides a kind of utilization and blocks the device that the mode of disconnected workroll bearing case solves the extraction operation roll of mill of problems such as bearing housing and backing roll be fragile.
In the extraction milling train that the utility model proposes the device of roll breakage comprise be installed in the car body end be used for the hook portion is connected with power set and be installed in car body the other end for colluding the limit assembly that drags the roll breakage bearing housing.
Described hook portion comprises the rectangular frame that is connected with the car body end by bolt, and this rectangular frame is provided with reclinate hook away from the end of car body.
Be installed in two locating parts of car body end between described limit assembly comprises and by pivot and two rectangle eave tiles that locating part flexibly connects with being separated with certain distance, and with the inner rocking pin that is connected of rectangle eave tile.
The limit assembly that the device of the extraction operation roll of mill that the utility model proposes adopts can be fixed bearing housing, and the stable bearing case just can not produce swing by working roll, so, when producing working roll, just can not damage backing roll; Simultaneously, because this device is by vertically producing disconnected working roll, working roll need not be bundled in producing process, its operating time is shorter relatively, has shortened and has colluded the processing time of dragging roll breakage, can improve the efficient of changing working roll.
Description of drawings:
Accompanying drawing 1 is that the master of the embodiment of the device of producing operation roll of mill that proposes of the utility model looks schematic diagram;
Accompanying drawing 2 is vertical views of Fig. 1.
The specific embodiment:
Referring to Fig. 1 and Fig. 2, these two accompanying drawings provide the surface structure schematic diagram of the embodiment of the device of producing operation roll of mill that the utility model proposes.This device comprises car body 1 and is installed in the hook portion 2 of car body 1 front end, and the limit assembly 3 that is installed in car body 1 rear end.Car body 1 comprises rectangle rack 11 and wheel 12, and the arc plate 13 that is complementary with the working roll shape is installed in rectangle rack 11.Hook portion 2 comprises rectangular frame 21, this rectangular frame 21 is provided with reclinate hook 22 away from the end of car body 1, rectangle rack 21 is connected by the end of bolt 23 with car body 1 away from an end of hook 22, after working roll being drawn on the car body 1, to link up with 22 and hang on the power set, by power set body 1 be pulled out from milling train.Limit assembly 3 comprises two locating part 31 and the rectangle eave tiles 32 that are made of plate, and the rocking pins 33 that are connected with rectangle eave tile 32 the inners, wherein, 31 rearward end that are installed in car body 1 of two locating parts with being separated with certain distance, and locating part 31 extends the end of car body 1 and flexibly connects by pivot 34 and rectangle eave tile 32, and rocking pin 33 is connected with the inner of rectangle eave tile 32.
In extracting milling train during roll breakage, earlier the working roll balance is stretched out, itself and roll surface are broken away from, the working roll that will break again is placed on the car body 1 that pushes in the mill stand, and the bearing housing on the working roll is dropped on the locating part 3, because rocking pin 33 is depressed in the bearing housing deadweight, the rocking pin of depressing 33 drives rectangle gib head 32 and lifts, make rectangle gib head 32 catch on the outer of bearing housing, in the rectangle rack 11 of disconnected working roll car body 1, to link up with 22 hang on the power set after, the recycling power set take out disconnected working roll.
