Description
Technical field
The utility model relates to a kind of location roller change bracket of Hot Rolling Mill, belongs to mill roll changing device technical field.
Background technology
Strip-mill strip general work just needs to change one action roller for 4 ~ 8 hours.Roller replacing mode main at present has following several: the first: adopt sleeve fashion roll change, its advantage is that equipment is simple, shortcoming to change by single roller, roll change is slower, change a pair working roll and about need 30 ~ 40 minutes, and must crane be taken, labor strength is large, and milling equipment is often subject to impact damage.The second: the roll change operation of large-scale hot-rolling machine group, generally adopt rectangular configuration, outside with the trapezoidal guiding location roller change bracket consistent with bearing block, to reach the object of fast roll changing, its shortcoming is that trapezoidal guiding location roller change bracket weight is large, and overhead traveling crane must be adopted to lift.The third: the roll-changing equipment of some 550mm and above large-sized rolling mills unit adopts locating dowel roller change bracket, and during roll change, crane falls in roller process needs manually to visually observe backing roll with whether accurate roller change bracket contraposition is, time-consuming, require great effort, dangerous again; For 450mm and following medium and small-scale rolling mill, the roller change bracket form of main employing is generally rectangular configuration, topping roll relies on the frictional force between bearing block and support to be driven by bottom roll completely and enters memorial archway, bottom roll is often caused can accurately to put in place owing to being directly subject to the push-pull effort of roll change oil cylinder in roll change process, and topping roll only relies on frictional force that roll spindle nose can not be made to enter completely in driven journal, make a big impact to roll change, extend roll changing time.
Except above main roll-changing method, China Patent No. 201020551166 discloses a kind of roller change bracket, this support is made up of topping roll bracing frame, bottom roll bracing frame and two oil-blooming guide-board bracing frames, the top of topping roll bracing frame is provided with the arc groove that topping roll middle with two coordinates, the bottom of topping roll bracing frame is provided with fin, and two sides of topping roll bracing frame are provided with rectangular recess; The bottom of bottom roll bracing frame is provided with the arc groove that bottom roll middle with two coordinates, and the top of bottom roll bracing frame is provided with the groove coordinated with the bottom fin of topping roll bracing frame; Oil-blooming guide-board bracing frame is provided with the arc groove coordinated with oil-blooming guide-board, and oil-blooming guide-board bracing frame is provided with the fin coordinated with the rectangular recess of two of topping roll bracing frame sides; Respectively be provided with the fin of oil-blooming guide-board bracing frame in the groove of two sides of topping roll bracing frame, the fin below topping roll bracing frame is arranged in the groove at bottom roll bracing frame top.This supporting structure is complicated, and weight is large, and inconvenient operation, needs overhead traveling crane to be coordinated equally.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, simple to operate, the mill roll support of efficiently and accurately, safety labor-saving.
The technical scheme solved the problems of the technologies described above is:
A kind of mill roll support, it is made up of gripper shoe, gusset, gripper shoe is two pieces of identical vertical rectangle plate faces, the plate face of two pieces of gripper shoes is relatively parallel, the height in the rectangular slab face of gripper shoe matches with the distance between topping roll and the relative roll surface of bottom roll, the two ends of gripper shoe have protruding block up and down respectively, distance between outside distance between the block of gripper shoe two ends and topping roll bearing block and bottom roll bearing block two ends matches, and link of boards is between two pieces of gripper shoes.
Above-mentioned mill roll support, described gusset is 2-3 block, the plate face of gusset and horizontal plane and be parallel to each other, and the two ends of gusset are connected with the gripper shoe vertical welding of both sides respectively.
Above-mentioned mill roll support, there is triangular chamfered the side relative with block, described gripper shoe two ends respectively.
The beneficial effects of the utility model are:
The utility model gripper shoe is between topping roll and bottom roll, support and stable topping roll, when roll change, the block at gripper shoe two ends is stuck in the two ends of topping roll bearing block and bottom roll bearing block, make roll change buggy or roll change planker topping roll can be driven to enter memorial archway together when dragging bottom roll, accurately locate when ensureing that topping roll and bottom roll enter memorial archway simultaneously, increase substantially operating efficiency, in hot tandem roll change process, also can realize multiple roll change simultaneously, greatly shorten roll changing time.The utility model structure is simple, and make easily, highly versatile, is applicable to the roll change of all 450mm and following medium and small-scale rolling mill.Deadweight of the present utility model is little, easy to operate, safe and reliable, and a people can independent operation, greatly reduction labour intensity and cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state schematic diagram of the present utility model.
In figure, mark is as follows: gripper shoe 1, gusset 2, block 3, topping roll 4, bottom roll 5, roller change bracket 6.
Detailed description of the invention
The utility model is made up of gripper shoe 1, gusset 2.
Show in figure, gripper shoe 1 is two pieces of identical vertical rectangle plate faces, the plate face of two pieces of gripper shoes 1 is relatively parallel, and there is triangular chamfered side, gripper shoe 1 two ends respectively, and the height in the rectangular slab face of gripper shoe 1 matches with the distance between topping roll 4 and the relative roll surface of bottom roll 5.
Show in figure, the two ends of gripper shoe 1 have protruding block 3 up and down respectively, and the distance between outside the distance between gripper shoe 1 two ends block 3 and topping roll bearing block and bottom roll bearing block two ends matches.
