Detailed Description
Example 1
Referring to fig. 1-2, in the present embodiment, the screw lifting tool includes a lifting bolt 10, an upper lifting plate 20 and a lower lifting plate 30, wherein the upper lifting plate 20 and the lower lifting plate 30 are oppositely screwed at two ends of the lifting bolt 10, the upper lifting plate 20 is configured into a U shape, an upper nut 21 for screwing with the lifting bolt 10 is welded between two ends of the upper lifting plate 20, the lower lifting plate 30 includes a left side plate 33 and a right side plate 32 which are oppositely arranged, and a lower nut 32 welded between the left side plate 33 and the right side plate 32, the upper nut 21 and the lower nut 31 have internal threads with opposite screwing directions, and a connecting hole 34 is formed at the lower ends of the left side plate 33 and the right side plate 32.
According to the embodiment, the lifting bolt 10 is rotated to drive the upper lifting plate 20 and the lower lifting plate 30 to synchronously move in opposite directions or reversely, so that the distance between the upper lifting plate 20 hung on the monorail trolley and the lower lifting plate 30 hung on the pump head is changed, the lifting height of the pump head is conveniently controlled, and the device has the advantage of simplicity and convenience in operation.
In this embodiment, alternatively, the upper hanger plate 20 and the lower hanger plate 30 are integrally disposed along the axial direction of the lifting bolt 10, the operation section 11 is disposed in the middle of the lifting bolt 10, and the clamping surfaces 12 parallel to each other are disposed on the peripheral surface of the operation section 11, so that the lifting bolt 10 can be clamped and fixed by a tool through the clamping surfaces 12, and further the rotation of the lifting bolt 10 is realized, as an example, the distances between two end surfaces of the lifting bolt 10 and the operation section 11 are equal, so as to improve the overall structural strength of the lifting bolt 10, and the lifting bolt 10 is designed into an integrally formed structure.
It should be understood that since the upper nut 21 and the lower nut 31 are respectively screwed on the lifting bolts 10 at both sides of the operation section 11, the threads at both sides of the operation section 10 have opposite screwing directions, i.e., the lifting bolts 10 have two threads having opposite screwing directions, and the interval between both the upper and lower lifting plates 20 and 30 can be changed when the lifting bolts 10 are rotated by the operation section 11.
In addition, the upper nut 21 and the lower nut 31 are each configured in a rectangular block shape as a whole, and the upper nut 21 and the lower nut 31 are kept in parallel as a whole, the left side plate 33 and the right side plate 32 are kept in parallel as a whole, and at the same time, the axis of the connecting hole 34 is kept perpendicular to the lifting bolt 10.
When the pump head is replaced, the upper hanger plate 20 is firstly hung on the monorail trolley, the lower hanger plate 30 is simultaneously hung with the pump head, then the tool is used for clamping the operation section 11 to rotate the lifting bolt 10, at this time, the upper hanger plate 20 and the lower hanger plate 30 move oppositely relative to the lifting bolt 10, so that the distance between the upper hanger plate 20 and the lower hanger plate 30 is reduced, the purpose of accurately lifting the pump head is finally achieved, and finally the pump head is dragged to horizontally move by utilizing the movement of the monorail trolley along the track.
While embodiments of the present utility model have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives, and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the utility model.
