Described elastic colloid and damping hole matched in clearance, the upper surface of this elastic colloid and the bottom close contact of damping hole, and the lower surface of elastic colloid and described bottom working roll bearing block close contact;
Described gland is positioned at damping hole, this gland has the through hole with described elastic damping mates, and gland is fixed on described top working roll bearing block;
The top of described alignment pin and the first locating hole matched in clearance, the bottom of alignment pin and described second locating hole interference fits.
Further, described gland and described top working roll bearing block are spirally connected fixing.
Further, be provided with sealing ring in the through hole of described gland, sealing circle and elastic colloid outer wall closely cooperate.
Further, the bottom of described damping hole is provided with adjustment backing plate, upper surface and the adjustment backing plate close contact of described elastic colloid.
Further, the upper surface of described bottom working roll bearing block is provided with cushion block, the lower surface of described elastic colloid and cushion block close contact.
Further, the upper surface of described bottom working roll bearing block has cushion block hole in the corresponding position with described damping hole, in this cushion block hole, be provided with cushion block, the lower surface of described elastic colloid and cushion block close contact.
The advantage that the utility model has and good effect are:
This duo mill has additional elastic colloid on the basis of existing technology, gland and alignment pin, when after screw-down structure removal pressure, top working roll bearing block is raised under the effect of elastic colloid, make, gap is there is between bottom working roll bearing block, bottom working roll bearing block is pulled out from frame, top working roll bearing block is under the effect of alignment pin, pull out from frame together with bottom working roll bearing block, without the need to making the positioning work of roll bearing seat and bottom working roll bearing block on carrying out again in this process, improve roll change efficiency, reduce the labour intensity of operative employee, eliminate potential safety hazard.

Detailed description of the invention
Now by reference to the accompanying drawings a kind of structure of duo mill is described in further detail.
As shown in Figure 2, a kind of duo mill, comprises two top working roll bearing blocks, 1, two bottom working roll bearing blocks 7, also comprises elastic colloid 3, alignment pin 8, gland 5; Two top working roll bearing blocks 1 are fore side top working roll bearing block and transmission side top working roll bearing block, and two bottom working roll bearing blocks 7 are fore side bottom working roll bearing block and transmission side bottom working roll bearing block; Elastic colloid 3 as shown in Figure 6;
As shown in figures 3-8, the lower surface of described top working roll bearing block 1 has multiple damping hole 9 and multiple first locating hole 10, the upper surface of described bottom working roll bearing block 7 has multiple second locating hole 12 in the corresponding position with the first locating hole 10;
