When the slide plate 91 is replaced, the position of the hook body 56 on the cross beam 51 is adjusted by moving the slide plate 561, and the height of the hook tip 564 is finely adjusted by rotating the hook lever 563, so that the hook tip 564 of the hook body 56 is aligned with the hole of the slide plate 91, and the slide plate 91 can be hooked.

When the slide plate 91 on the universal mill housing 9 is overhauled or replaced by the replacing device,

1) firstly, assembling a replacing device, installing a first frame 1 of the replacing device into a universal mill housing 9, adjusting the height of the replacing device through a height supporting block 7 according to the internal condition of the mill housing and the position of a sliding plate 91 to be replaced, enabling a first horizontal section 12 to be close to the upper part of the sliding plate 91 to be overhauled or replaced, installing a sliding block 54 of a hook device 5 into a first groove 13 of the first horizontal section 12 of one first frame 1, and installing another sliding block 54 of the hook device 5 into a first groove 13 of the first horizontal section 12 of another first frame 1; the two trolleys 34 in the third frame 3 are moved into the third grooves 33 corresponding to the other ends of the two first horizontal segments 12, respectively.

2) Adjusting the position of the sliding plate 561 of the hook body 56 in the fifth groove 52 of the beam 51, rotating the beam 51 to make the hook tip 564 of the hook body 56 extend into the hole on the sliding plate 91 and detach the sliding plate 91, longitudinally pushing the hook device 5 to move along the first horizontal section 12 of the first frame 1 (i.e. the hook device 5 moves along the first groove 13 by using the slider 54), pausing when the two sliders 54 move to the two trolleys 34 respectively, laterally pushing the hook device 5 to move along the third frame 3 (at this time, the hook device 5 moves along the third groove 33 by using the two trolleys 34), pausing when the two trolleys 34 move to the position where the fourth frame 4 is connected with the third frame 3, longitudinally pushing the hook device 5 to move along the fourth frame 4 and the second horizontal section 22 of the second frame 2 (i.e. the hook device 5 moves along the fourth groove 41 and the second groove 23 by using the slider 54), when the slider 54 is moved to the end of the second horizontal section 22 of the second frame 2, it is stopped, and the slide plate 91 on the hook body 56 is repaired or replaced.

3) After the sliding plate 91 is repaired or replaced, the hook device 5 moves to one end of the first horizontal section 12 of the first frame 1 sequentially through the second groove 23, the fourth groove 41, the third groove 33 and the first groove 13, and the sliding plate 91 is installed on the universal mill housing 9, so that the operation is completed.

From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:

the utility model provides a device for changing slide plate 91 of universal mill housing 9, includes first frame 1, second frame 2, third frame 3 and hook assembly 5, and first frame 1 is located universal mill housing 9, and second frame 2 is located outside universal mill housing 9, through the removal of hook assembly 5 in first frame 1, second frame 2 and third frame 3 respectively, realizes maintenance and change universal mill housing 9 slide plate 91.

The replacing device is convenient to install, and the efficiency and the safety of overhauling and replacing the sliding plate 91 of the universal mill housing 9 are improved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
