Technical Field

The invention belongs to the field of continuous rolling mill equipment, and particularly relates to a green environment-friendly Z-shaped asymmetric steel sheet pile continuous rolling mill guide structure.

Background

The continuous rolling mill for rolling the Z-shaped steel sheet pile is provided with a guide corresponding to the roller. The guide comprises an upper guide and a lower guide and a vertical side guide, and the installation mode of the guide directly adopts a wedge-shaped block on a guide beam to compress the guide or welds the guide on the guide beam.

However, the two installation methods have certain defects, which are mainly reflected in that:

1. the guide is installed in a wedge block pressing mode, the guide is not fixed firmly due to machining precision and wedge block deformation caused by long-term use, and the guide is easy to shift and deform after being rolled for many times, so that the quality of a final rolled finished product is affected.

2. The guide adopts the mode of welding the guide on the guide beam to be installed, although the guide strength can be ensured, the guide can not be adjusted after the welding is finished, the guide and the guide beam can be separated only by the fire operation, the adjustment time of the guide is greatly increased, the structure of the guide and the guide beam is extremely easy to damage by the fire operation, and the time and the labor are wasted.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a green environment-friendly Z-shaped asymmetric steel sheet pile continuous rolling mill guide structure to overcome the defects in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme:

the guide and guard structure of the green environment-friendly Z-shaped asymmetric steel sheet pile tandem mill corresponds to a tandem mill for rolling asymmetric Z-shaped steel sheet piles, and the tandem mill is provided with an upper roller and a lower roller as well as a tandem mill housing corresponding to the upper roller and the lower roller; the method is characterized in that: a guide box is fixedly arranged between the inner walls of the memorial archways of the continuous rolling mill, and two sides of the guide box are respectively fixed on the inner walls of the corresponding memorial archways through telescopic fastening devices; the upper part of the guide box is provided with an upper guide beam which is fixedly provided with an upper guide; the lower part of the guide box is provided with a lower guide beam which is fixedly arranged with the lower guide; the upper guide corresponds to the upper roller, and the lower guide corresponds to the lower roller; vertical side guides and guards are respectively installed on two sides of the guide and guard box, and the positions of the vertical side guides and guards correspond to the edge positions of the upper roller and the lower roller.

According to the optimized scheme, the telescopic fastening device comprises a movable threaded rod which is in threaded connection with the side edge of the guide box, and a fastening seat is arranged at the outer side end of the movable threaded rod; the fastening seat is fastened on the inner wall of the memorial archway under the action of the movable threaded rod.

According to the optimized scheme, two threaded seats are symmetrically arranged on two sides of the guide box.

According to the optimized scheme, the threaded seat comprises a body arranged on the side edge of the guide box, a threaded through hole penetrates through the body, and an internal thread is arranged in the threaded through hole; the movable threaded rod is provided with an external thread, the external thread and the internal thread are connected together in a threaded connection mode, and the movable threaded rod extends out or retracts by means of movement generated by thread rotation in the rotation process.

According to the optimized scheme, the guide and guard box comprises a box body, and a waist-shaped long hole for connection is formed in the bottom of the box body; a lower guide installation surface corresponding to the lower guide, two side guide installation surfaces corresponding to the two vertical side guides and two left and right upper guide installation surfaces corresponding to the upper guide are arranged in the box body.

Due to the adoption of the technical scheme, compared with the prior art, the invention has the beneficial effects that:

1. the invention adopts the structure of the guide box, all the guides are fixed on the guide box, and the guide box form an integral structural member. The contrast is original directly adopts the wedge on leading the guarding roof beam to compress tightly to lead and defends or will lead the fixed mode of leading the guarding of defending the welding on leading the guarding roof beam, no matter receive the impact in-process at rolling, leads the stability of guarding, leads and defends dismouting adjustment time, leads the bulk strength of guarding and leads the axial position adjustment convenience of defending and all have very showing promotion, improves effective rolling time, reduces rolling cost and field maintenance personnel's working strength.

2. The bottom of the guide box is connected to a continuous rolling mill through the waist-shaped long hole and the bolt, the fine adjustment movement of the whole guide box can be realized by loosening the bolt, and the fixation of the guide box can be realized by screwing the bolt.

3. The side edge of the guide box is fixed with the inner wall of the continuous rolling mill housing through the telescopic movable threaded rod, so that higher stability is obtained, and the guide adjusting time is greatly reduced.

The invention is further illustrated with reference to the figures and examples.
