Furthermore, after the rolling mill is placed on the trolley, the three groups of positioning blocks are in surface contact with the rolling mill base.

Further, three group's locating piece bottoms all are cuboid columnar structure, and three group's locating piece tops are towards keeping away from the inclined plane that rolling mill base direction set up.

Furthermore, a positioning pin is arranged on any one of the rolling mill base and the trolley, and a positioning pin hole is arranged on the other one of the rolling mill base and the trolley.

Furthermore, the rolling mill and the trolley are both provided with identification strips for judging and observing the positioning accuracy between the rolling mill and the trolley.

Furthermore, a driving mechanism is arranged on the mounting plate, and an output shaft of the driving mechanism is fixed with the trolley.

Furthermore, two guide plates are arranged on the mounting plate, and an output shaft of the driving mechanism penetrates through the two guide plates.

As above, the utility model discloses a vertical rolling mill hoists positioner fast has following beneficial effect:

due to the arrangement of the three groups of positioning blocks, the placing space of the rolling mill base is convenient to limit, and whether the rolling mill base can enter the three groups of positioning blocks to judge whether the positioning of the rolling mill base is accurate or not can be judged by observing whether the rolling mill base can enter the three groups of positioning blocks or not in the descending process of the rolling mill base.

Detailed Description

Reference numerals in the drawings of the specification include: the device comprises a mounting plate 1, a track 2, a trolley 3, a roller 4, an output shaft 5, a guide plate 6, a rolling mill base 7, a first group of positioning blocks 8, a second group of positioning blocks 9, a third group of positioning blocks 10 and a positioning pin 11.

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Examples

As shown in fig. 1 and fig. 2, the embodiment provides a quick hoisting and positioning device for a vertical rolling mill, which includes a mounting plate 1 and a trolley 3, wherein a rail 2 is arranged on the mounting plate 1. The bottom of the trolley 3 is provided with a roller 4, and the roller 4 is matched with the track 2. Three groups of positioning blocks are arranged on the upper surface of the trolley 3, wherein a first group of positioning blocks 8 are used for limiting the front side wall of the rolling mill base 7, a second group of positioning blocks 9 are used for limiting the side walls of the two sides of the rolling mill base 7, and a third group of positioning blocks 10 are used for limiting the rear side wall of the rolling mill base 7. The placing space of the rolling mill base 7 is limited by three groups of positioning blocks, each group of positioning blocks comprises two positioning blocks, the bottom ends of the three groups of positioning blocks are in a cuboid column shape, and the top ends of the three groups of positioning blocks are inclined planes which are arranged towards the direction far away from the rolling mill base 7, so that the rolling mill base 7 can be conveniently positioned in the placing space. In this embodiment, each set of positioning blocks includes two positioning blocks, and after the rolling mill base 7 is positioned and installed, the contact surfaces of the three sets of positioning blocks and the rolling mill base 7 are planes, so as to avoid scratching the rolling mill base 7.

A driving mechanism for driving the trolley 3 is fixed on the trolley 3, an output shaft 5 of the driving mechanism is arranged in parallel with the slide rail, and the output shaft 5 of the driving mechanism is fixed with the trolley 3. Two guide plates 6 for guiding the output shaft 5 of the driving mechanism are arranged on the mounting plate 1, and the output shaft 5 of the driving mechanism penetrates through the two guide plates 6 to avoid the output shaft 5 of the driving mechanism from deviating. In the embodiment, the driving mechanism can be a cylinder, an oil cylinder, a linear motor and the like.

The upper surface of the trolley 3 is also provided with a positioning pin 11 for positioning with the rolling mill base 7, and the rolling mill base 7 is correspondingly provided with a positioning pin 11 hole for further positioning the rolling mill base 7 and the trolley 3. In this embodiment, the positioning pin 11 may be provided on the carriage 3, and the positioning pin 11 is correspondingly provided on the rolling mill base 7 for positioning.

In addition, the trolley 3 and the rolling mill base 7 can be provided with identification strips, and whether the positioning between the trolley 3 and the rolling mill is accurate or not is judged according to the relative positions of the identification strips between the trolley 3 and the rolling mill base. The arrangement of the identification strip is convenient for accurately observing whether the trolley 3 and the rolling mill base 7 are accurately positioned. In the embodiment, the identification strips on the trolley 3 are arranged on the second group of positioning blocks 9, the identification strips on the rolling mill base 7 are correspondingly arranged, and whether the positioning between the two is accurate is judged by judging whether the identification strips are aligned between the two.

During specific implementation, the trolley 3 is driven to move by the driving mechanism, then a new rolling mill is hoisted above the trolley 3 and descends, so that the new rolling mill base 7 is located between the three groups of positioning blocks, whether the positioning between the rolling mill base 7 and the trolley 3 is accurate is judged by observing the identification strip on the new rolling mill base 7, whether the positioning pin 11 can enter the positioning pin 11 hole after the rolling mill descends is convenient to determine, and the rapid positioning and installation between the trolley 3 and the rolling mill is realized.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
