Abstract
The utility model discloses a main drive shaft bracket device for a rolling mill. The bracket device comprises a pair of clamping plates, a clamping drive mechanism and a pair of stopper blocks, wherein each stopper block is Gamma-shaped and is axially sleeved on the corresponding clamping plate. The inner side of each stopper block is fixedly connected with the corresponding clamping plate via a radially-arranged bolt. A flat key is arranged between the inner side surface of each stopper block and the outer side surface of the corresponding clamping plate, and is used for force bearing purpose. When a flat-head sleeve is forced, force is born by the stopper blocks mostly via the flat keys and via the radially-arranged bolts, thereby avoiding bolt fracture due to the generation of rotating force moment, prolonging the service lifetime of the stopper blocks and guaranteeing the operating continuity.
Description
Technical field
The utility model relates to the mill roll servicing unit, more particularly, relates to a kind of mill's main drive shaft bracket system.
Background technology
All kinds of large-sized rolling mills in integrated iron and steel works mainly are that the final drive shaft bracket system all is installed in hot rolling, the heavy and medium plate mill, and it mainly acts on is when mill roll, keep the position of final drive shaft homalocephalus cover, so that return the dress working roll fast.See also shown in Figure 1, this bracket system 10 comprises a pair of clamping plate 11, clamps driving mechanism 12 and a pair of stop block 13, each clamping plate 11 all connects one and clamps driving mechanism 12, by clamping the driving of driving mechanism 12, makes two clamping plates 11 upwards clamp the homalocephalus cover 1 of final drive shaft from the footpath; Each stop block 13 is
Shape, two stop blocks are symmetrical arranged, and the bolt 14 of its side by axial setting be connected and fixed with the end face of two clamping plates 11 respectively, play the axial location effect of homalocephalus cover 1.But, because final drive shaft is subjected to the thrust of horizontal equilibrium cylinder, can produce an outside power, this power is transferred to homalocephalus when overlapping 1 head, can act on the limit portion of stopper 13, forms the turning moment around bolt 14 on stopper 13, easily make bolt 14 can't bear turning moment, finally cause bolt 14 frequently to rupture, cause roll change effectively to carry out, influenced the production efficiency of enterprise.
The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of mill's main drive shaft bracket system, and this bracket system can improve stressing conditions, avoids its stopper to rupture.
For achieving the above object, the utility model adopts following technical scheme:
This mill's main drive shaft bracket system comprises a pair of clamping plate, clamps driving mechanism and a pair of stop block, clamps driving mechanism and links to each other with clamping plate, and described each stop block is
Shape, and axially being set on the corresponding clamping plate, the side of each stopper is connected and fixed with corresponding clamping plate by the bolt that radially is provided with, and also is provided with in order to stressed flat key between the lateral surface of the medial surface of stop block and corresponding clamping plate.
The bolt quantity that the inboard of described stop block radially is provided with is four.
The medial surface of described stop block and the lateral surface of clamping plate are provided with corresponding keyway, and flat key is located in the keyway.
In technique scheme, mill's main drive shaft bracket system of the present utility model comprises a pair of clamping plate, clamps driving mechanism and a pair of stop block, and each stop block is
Shape, and axially being set on the corresponding clamping plate, the side of stop block are connected and fixed with corresponding clamping plate by the bolt that radially is provided with respectively, and also are provided with in order to stressed flat key between the lateral surface of the medial surface of stop block and corresponding clamping plate.When homalocephalus overlaps when stressed, stopper is born most power by flat key, and is born pulling force by radial bolts, thereby avoids producing revolving force moment and cause bolt fracture, has prolonged the service life of stop block, and has guaranteed the continuity of operation.
Description of drawings
Fig. 1 is the schematic top plan view of the mill's main drive shaft bracket system of prior art;
Fig. 2 is the schematic top plan view of mill's main drive shaft bracket system of the present utility model.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Figure 2, mill's main drive shaft bracket system 20 prior aries of the present utility model are basic identical, equally also comprise a pair of clamping plate 21, clamp driving mechanism 22 and a pair of symmetrically arranged stop block 23, clamp driving mechanism 22 and link to each other with corresponding clamping plate 21.Different is that described each stop block 23 is
Shape, and axially be set on the corresponding clamping plate 21, the side of stop block 23 is connected and fixed with corresponding clamping plate 21 by the bolt 24 that radially is provided with respectively, and also be provided with in order to stressed flat key 25 between the lateral surface of the medial surface of stop block 23 and corresponding clamping plate 21, promptly on the lateral surface of the medial surface of stop block 23 and clamping plate 21, be provided with corresponding keyway, and flat key 25 is located in the keyway.In addition, bolt 24 quantity that radially are provided with of the inboard of stop block 23 be four preferable.
Adopt bracket system 20 of the present utility model, in use, when homalocephalus overlaps stressed, stopper 23 is born most power by flat key 25, and born pulling force by radial bolts 24, thereby avoid producing revolving force moment and cause bolt 24 fractures, prolonged the service life of stop block 23, and guaranteed the continuity of operation.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
