Technical field
The present invention relates to the installation of milling train machinery screwdown gear, be specifically related to a kind of nut mounting device and method of rolling mill screwdown device.
Background technology
The nut of milling train machinery screwdown gear is installed in (milling train) frame top mounting hole, installation (nut is installed from nut mounting hole bottom) need be hung in from framework window during installation, conventional construction method adopts driving directly lifting, coordinated by chain block and attach it to position, following problem is there will be: 1, unstable during lifting in installation process, easy and rolling-mill housing collides, and destroys finished surface, affects precision of equipment installation; And need workmen to be positioned by manpower firmware, operating difficulties.2, between screw box and mounting hole, gap is little, if nut has to tilt just cannot be in place smoothly in lifting, need repeatedly adjust, installation effectiveness is low.
Summary of the invention
For above-mentioned technical matters, the object of the present invention is to provide a kind of nut mounting device and method of rolling mill screwdown device, when this device or method mounting nuts, hoisting process is not only steady but also laborsaving, easy to adjust, contraposition is accurate.
For achieving the above object, the technical solution used in the present invention is:
The nut mounting device of rolling mill screwdown device, is characterized in that: it comprises a C shape steel structure suspender, and suspender upper end is provided with hanger, and bottom is planche cross structure; Described planche cross structure is provided with criss-cross flitch, the end on planche cross structure four limits is equipped with block; Jack is all laid in four limits of described planche cross structure, and described jack is between criss-cross flitch end and block; During use, nut is placed on criss-cross flitch and jack, and nut lower end surrounds by four blocks.
Described suspender is that H profile steel is welded, and the angle of each welding is welded with reinforcement set square.
The nut installation method of rolling mill screwdown device, is characterized in that it comprises the following steps:
S1, the nut mounting device of rolling mill screwdown device mated according to the large little makings one of screwdown gear nut;
Nut hangs onto on flitch and jack, and comes levelness and the squareness of adjusting nut by adjusting four jacks by S2, utilization driving;
S3, adjusted after, first sling with the nut mounting device of hanging apparatus by rolling mill screwdown device, height corresponding with rolling-mill housing top nut mounting hole; Horizontal direction moves the nut mounting device of rolling mill screwdown device again, makes nut be positioned at immediately below nut mounting hole; Nut is installed in nut mounting hole by the nut mounting device finally promoting rolling mill screwdown device.
In the process that nut is installed in step s3, again can adjust four jacks, with the degree of dip of adjusting nut.
Beneficial effect of the present invention: when this device or method mounting nuts, hoisting process not only steady but also laborsaving, easy to adjust (adjusting nut squareness and level convenient and swift), contraposition are accurate.
