Description

Nut mounting device for rolling mill holding down device

technical field

The utility model relates to the installation of a rolling mill mechanical pressing device, in particular to a nut installation device of the rolling mill pressing device.

Background technique

The nut of the mechanical pressing device of the rolling mill is installed in the mounting hole on the top of the (rolling mill) frame. During installation, it needs to be hoisted in from the window of the frame (the nut is installed from the bottom of the nut mounting hole). The traditional construction method is to directly hoist it by driving. It is installed in place through the cooperation of chain hoists, and the following problems will occur during the installation process: 1. It is unstable during hoisting, and it is easy to collide with the rolling mill frame, damage the processing surface, and affect the installation accuracy of the equipment; and the construction personnel need to use manpower to stabilize the equipment Positioning is difficult to operate. 2. The gap between the pressed nut and the installation hole is small. If the nut is tilted during hoisting, it cannot be installed in place smoothly. Repeated adjustments are required, and the installation efficiency is low.

Utility model content

In view of the above technical problems, the purpose of this utility model is to provide a nut installation device for a rolling mill pressing device. When the device installs nuts, the hoisting process is stable, labor-saving, easy to adjust, and accurate in position.

For realizing above-mentioned purpose, the technical scheme that the utility model takes is:

The nut installation device of the rolling mill pressing device is characterized in that it includes a C-shaped steel structure sling, the upper end of the sling is provided with lifting lugs, and the lower part is a horizontal cross structure; the horizontal cross structure is provided with a cross-shaped wooden square, Blocks are provided on the ends of the four sides of the horizontal cross structure; jacks are placed on the four sides of the horizontal cross structure, and the jack is located between the ends of the cross-shaped wooden square and the blocks; when in use, The nut is placed on the cross-shaped wooden square and the jack, and four stoppers surround the lower end of the nut.

The hanger is welded by H-shaped steel, and each welded corner is welded with a reinforcing triangular plate.

The beneficial effects of the utility model: when the device is installed with nuts, the hoisting process is stable and labor-saving, the adjustment is convenient (it is convenient and quick to adjust the verticality and level of the nuts), and the alignment is accurate.

Detailed ways

In order to better understand the utility model, the technical solutions of the utility model will be further described below in conjunction with specific embodiments and accompanying drawings.

The nut mounting device of the rolling mill pressing device, as shown in Figures 1 and 2, includes a C-shaped steel structure sling 1, the upper end of the sling 1 is provided with a lifting lug 5, and the lower part is a horizontal cross structure; A cross-shaped wooden square 4 is provided, and stoppers 2 are provided on the ends of the four sides of the horizontal cross structure (the distances from the four stoppers 2 to the center of the horizontal cross structure are equal to the radius of the lower end of the nut 7); the horizontal cross Jacks 3 are placed on the four sides of the structure (the jack 3 is a 10t low-profile screw jack, and the height is lower than the height of the wooden square 4 in the contracted state), and the jack 3 is located at the end of the cross-shaped wooden square 4 During use, the nut 7 is placed on the cross-shaped wooden square 4 and the jack 3, and the four stoppers 2 surround the nut 7 lower ends.

The spreader 1 is welded by H-shaped steel (the specification of the H-shaped steel is H150-H200), and each welded angle is welded with a reinforcing triangle plate 6 (the angles are all right angles).

The method of using the nut installation device of the rolling mill pressing device includes the following steps (as shown in Figure 3):

S1, according to the size of the pressing device nut 7, make a matching nut installation device of the rolling mill pressing device;

S2, utilize driving to hang the nut 7 on the wooden side 4 and the jack 2, and adjust the levelness and verticality of the nut 7 by adjusting the four jacks 2;

S3. After the adjustment is completed, first use the hoisting device to lift the nut mounting device of the rolling mill pressing device, and the height corresponds to the nut mounting hole 8 on the top of the rolling mill stand; then move the nut mounting device of the rolling mill pressing device horizontally to make the nut 7 is located directly below the nut mounting hole 8; the nut mounting device of the lifting rolling mill depressing device installs the nut 7 in the nut mounting hole 8 at last.

During the installation of the nut 7 in step S3, the four jacks 2 can be adjusted again (slightly) to adjust the inclination of the nut 7 (to make the nut 7 more quickly installed in place).

The above embodiments are only preferred solutions of the present utility model, rather than limitations of the present utility model. Those skilled in the relevant technical fields can also make various transformations or modifications without departing from the spirit and scope of the present utility model. , so all equivalent technical solutions all fall into the protection scope of the present utility model.
