Compared with the prior art, the beneficial effects of the utility model are that: a lifting adjusting mechanism for a connecting shaft of a universal rolling mill can make up for the dependence of the lifting of the connecting shaft on a crane when the rolling mill is replaced, and can realize the simultaneous wire-entering work of a plurality of rolling mills. A large amount of time is saved for the wire changing work, and the wire changing process is accelerated.
Description
Technical Field
The utility model relates to a rolling mill production line technical field in the steel rolling technology especially relates to a universal mill connecting axle lift guiding mechanism.
Background
In the production process of steel rolling, the production line replacement of a rolling mill is a frequent work. When different types of rolling mills are replaced, the distance between the upper roller and the lower roller can be changed, the flat head sleeve connected with the original rolling mill can be dislocated, and the flat head sleeve is not easy to correct when being installed in the rolling mill, so that the installation is time-consuming and labor-consuming.
The previous way of adjusting the connecting shaft is achieved by means of a crane. The method is limited by conditions in a factory, only can be adjusted singly, and needs repeated hanging for many times in the whole wire changing process. Because only one crane is provided, other hoisting work on the live wire can only be suspended, and the whole wire replacement work is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a universal mill connecting axle lift guiding mechanism can compensate the lift of connecting axle when changing the rolling mill and to the reliance of crane to can realize the work of many rolling mills income line simultaneously. A large amount of time is saved for the wire changing work, and the wire changing process is accelerated.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a universal mill connecting axle lift guiding mechanism, includes top roll connecting axle, lower roll connecting axle, spiale bracket, still includes hydraulic cylinder, pneumatic cylinder base, chain, fixed pulley, the upper end at the spiale bracket is fixed to the pneumatic cylinder base, hydraulic cylinder fixes on the pneumatic cylinder base, hydraulic cylinder's piston is articulated with top roll connecting axle bearing frame, at the upper end of spiale bracket, two sets of fixed pulleys of bilateral symmetry installation of pneumatic cylinder base, top roll connecting axle bearing frame is connected to the one end of chain, and lower roll connecting axle bearing frame is connected to the other end of chain.
An outlet balance valve is arranged on an oil outlet pipeline of the lifting hydraulic cylinder.
Compared with the prior art, the beneficial effects of the utility model are that:
a lifting adjusting mechanism for a connecting shaft of a universal rolling mill can make up for the dependence of the lifting of the connecting shaft on a crane when the rolling mill is replaced, and can realize the simultaneous wire-entering work of a plurality of rolling mills. A large amount of time is saved for the wire changing work, and the wire changing process is accelerated.
Drawings
FIG. 1 is a schematic structural view of a universal mill connecting shaft lifting adjusting mechanism of the present invention;
fig. 2 is a side view of fig. 1.
In the figure: 1-lifting hydraulic cylinder, 2-hydraulic cylinder base, 3-oil outlet pipeline, 4-outlet balance valve, 5-lifting ring, 6-lifting lug, 7-fixed pulley, 8-chain, 9-upper roller connecting shaft bearing seat, 10-lower roller connecting shaft bearing seat, 11-connecting shaft bracket, 12-pin shaft, 13-oil outlet pipeline, 14-upper roller connecting shaft and 15-lower roller connecting shaft.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
referring to fig. 1-2, a universal mill connecting shaft lifting adjusting mechanism comprises an upper roll connecting shaft 14, a lower roll connecting shaft 15, a connecting shaft bracket 11, a lifting hydraulic cylinder 1, a hydraulic cylinder base 2, a chain 8 and fixed pulleys 7, wherein the hydraulic cylinder base 2 is fixed at the upper end of the connecting shaft bracket 11, the lifting hydraulic cylinder 1 is fixed on the hydraulic cylinder base 2, a piston of the lifting hydraulic cylinder 1 is hinged to an upper roll connecting shaft bearing block 9, two groups of fixed pulleys 7 are symmetrically arranged at the upper end of the connecting shaft bracket 11 and on two sides of the hydraulic cylinder base 2, one end of the chain 8 is connected with the upper roll connecting shaft bearing block 9, and the other end of the chain 8 is connected with a lower roll connecting shaft bearing block 10.
An outlet balance valve 4 is arranged on the oil outlet pipeline 3 of the lifting hydraulic cylinder 1.
A hydraulic cylinder base 2 is welded on the upper cover of the spindle bracket 11, and the lifting hydraulic cylinder 1 is fixed on the hydraulic cylinder base 2 through bolts. A lifting lug 6 is welded on the upper roll connecting shaft bearing seat 9. A lifting ring 5 is arranged on a piston head of the lifting hydraulic cylinder 1, and a lifting lug 6 is hinged with the lifting ring 5 through a pin shaft 12.
A chain 8 is connected between the upper roller connecting shaft bearing block 9 and the lower roller connecting shaft bearing block 10. When the upper roller connecting shaft 14 is lifted independently, the lower roller connecting shaft 15 is reversely linked through the chain 8. Therefore, the upper connecting shaft and the lower connecting shaft can be opened and closed together, the central line of the center distance is not changed, and the upper connecting shaft and the lower connecting shaft can be aligned with the roller of the rolling mill simultaneously when the rolling mill is installed.
The outlet balance valve 4 on the oil outlet pipeline 3 of the lifting hydraulic cylinder 1 can prevent accidents caused by sudden unloading of the lifting hydraulic cylinder 1.
The universal rolling mills are all multiple on the production line, the utility model discloses can all realize independent operation on every universal rolling mill, so can realize the work that many rolling mills were changed simultaneously. A great deal of time is saved.
