Description
Technical field
The utility model relates to the installation of milling train machinery screwdown gear, is specifically related to a kind of nut mounting device 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.
Utility model content
For above-mentioned technical matters, the purpose of this utility model is the nut mounting device providing a kind of rolling mill screwdown device, and during this device mounting nuts, hoisting process is not only steady but also laborsaving, easy to adjust, contraposition is accurate.
For achieving the above object, technical solution adopted in the utility model 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 beneficial effects of the utility model: during this device mounting nuts, hoisting process not only steady but also laborsaving, easy to adjust (adjusting nut squareness and level convenient and swift), contraposition are accurate.

Fig. 2 is that the A-A of the nut mounting device of rolling mill screwdown device in Fig. 1 is to schematic diagram.
Fig. 3 is the nut mounting device using method schematic diagram of rolling mill screwdown device.
In figure: 1-suspender, 2-block, 3-jack, 4-flitch, 5-hanger, 6-strengthens set square, 7-nut, 8-nut mounting hole.
Detailed description of the invention
In order to better understand the utility model, below in conjunction with specific embodiments and the drawings, the technical solution of the utility model is further illustrated.
The nut mounting device of rolling mill screwdown device, as shown in Figure 1, 2, it comprises a C shape steel structure suspender 1, and suspender 1 upper end is provided with hanger 5, and bottom is planche cross structure; Described planche cross structure is provided with criss-cross flitch 4, the end on planche cross structure four limits is equipped with block 2(tetra-blocks 2 are equal to nut 7 lower end radius to the distance of planche cross structure centre); It is the short lifting screw of 10t that jack 3 described in jack 3(is all laid on four limits of described planche cross structure, and height is lower than the height of flitch 4 in a contracted state), described jack 3 is between criss-cross flitch 4 end and block 2; During use, nut 7 is placed on criss-cross flitch 4 and jack 3, and nut 7 lower end surrounds by four blocks 2.
Described suspender 1 is welded (specification of described H profile steel is H150 ~ H200) for H profile steel, and the angle of each welding is welded with to be strengthened angle described in set square 6(and be right angle).
The nut mounting device using method of rolling mill screwdown device, it comprises the following steps (as shown in Figure 3):
S1, the nut mounting device of rolling mill screwdown device mated according to the large little makings one of screwdown gear nut 7;
Nut 7 hangs onto on flitch 4 and jack 2, and comes levelness and the squareness of adjusting nut 7 by adjusting four jacks 2 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 8; Horizontal direction moves the nut mounting device of rolling mill screwdown device again, makes nut 7 be positioned at immediately below nut mounting hole 8; Nut 7 is installed in nut mounting hole 8 by the nut mounting device finally promoting rolling mill screwdown device.
In the process that nut 7 is installed in step s3, can again carry out (trace) adjustment, with the degree of dip of adjusting nut 7 (making nut 7 be in place more efficiently) to four jacks 2.
Above embodiment is only the preferred version of the utility model; but not to restriction of the present utility model; person skilled in the relevant technique; when not departing from spirit and scope of the present utility model; various conversion or modification can also be made; therefore all equivalent technical schemes, all fall into protection domain of the present utility model.
