Description

Technical Field

[0001] The present invention belongs to the field of continuous rolling mill equipment, and more specifically, relates to a green and environmentally friendly Z-shaped asymmetric steel sheet pile continuous rolling mill guide structure. Background Art

[0002] The continuous rolling mill for rolling Z-shaped steel sheet piles is equipped with guides corresponding to the rolling rollers. The guides include upper and lower guides and vertical side guides. They are installed by directly pressing the guides with wedge blocks on the guide beam or by welding them to the guide beam.

[0003] However, both of the above two installation methods have certain defects, which are mainly reflected in:

[0004] 1. The guide is installed by pressing with a wedge block. Due to the processing accuracy and the deformation of the wedge block caused by long-term use, the guide will eventually be fixed unreliably. After multiple rolling, the guide is very likely to shift and deform, affecting the quality of the final rolled product.

[0005] 2. The guide guard is installed by welding it to the guide guard beam. Although the strength of the guide guard can be guaranteed, the guide guard cannot be adjusted after welding. Hot work is required to separate the guide guard and the guide guard beam, which greatly increases the adjustment time of the guide guard. Hot work is very likely to damage the structure of the guide guard and the guide guard beam, which is time-consuming and labor-intensive. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a green and environmentally friendly Z-type asymmetric steel sheet pile continuous rolling mill guide structure to solve the defects of the existing technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The green and environmentally friendly Z-type asymmetric steel sheet pile continuous rolling mill guide structure corresponds to the continuous rolling mill used for rolling asymmetric Z-type steel sheet piles. The continuous rolling mill is provided with upper rollers and lower rollers, as well as continuous rolling mill arches corresponding to the upper rollers and lower rollers on the continuous rolling mill; it is characterized in that: a guide box is fixedly installed between the inner walls of the arches of the continuous rolling mill, and the two sides of the guide box are respectively fixed on the inner walls of the opposite arches through telescopic fastening devices; the upper part of the guide box is provided with an upper guide beam, and the upper guide beam is fixedly installed with an upper guide; the lower part of the guide box is provided with a lower guide beam, and the lower guide beam is fixedly installed with the lower guide; the upper guide corresponds to the upper roller, and the lower guide corresponds to the lower roller; vertical side guides are respectively installed on both sides of the guide box, and the positions of the vertical side guides correspond to the edge positions of the upper roller and the lower roller.

[0009] According to the optimized solution, the telescopic fastening device includes a movable threaded rod threadedly connected to the side of the guide box, and a fastening seat is provided at the outer end of the movable threaded rod; the fastening seat is fastened to the inner wall of the archway under the action of the movable threaded rod.

[0010] According to the optimized solution, two threaded seats are symmetrically provided on both sides of the guide box.

[0011] The optimized solution is that the threaded seat includes a main body installed on the side of the guide box, a threaded through hole is provided on the main body, and an internal thread is provided in the threaded through hole; an external thread is provided on the movable threaded rod, and the external thread and the internal thread are connected together by a threaded connection, and when the movable threaded rod rotates, the movement generated by the rotation of the thread is used to realize the extension or retraction of the movable threaded rod.

[0012] The optimized solution is that the guide box includes a box body, and the bottom of the box body is provided with a waist-shaped long hole for connection; the box body is provided with a lower guide installation surface corresponding to the lower guide, two side guide installation surfaces corresponding to the two vertical side guides, and two upper guide installation surfaces on the left and right corresponding to the upper guide.

[0013] Due to the adoption of the above technical solution, compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This invention utilizes a guide box structure to secure all guides, forming a single, integrated structure. Compared to existing guide fixing methods that directly compress the guides with wedges on the guide beam or weld them to the beam, this significantly improves guide stability, installation and disassembly time, overall guide strength, and ease of axial position adjustment during rolling impacts. This increases effective rolling time, reduces rolling costs, and reduces the workload of on-site maintenance personnel.

[0015] 2. The bottom of the guide box of the present invention is connected to the continuous rolling mill through waist-shaped long holes and bolts. The guide box can be fine-tuned and moved as a whole by loosening the bolts, and can be fixed by tightening the bolts.

[0016] 3. The side of the guide box of the present invention is fixed to the inner wall of the continuous rolling mill arch through a retractable movable threaded rod, thereby achieving higher stability and greatly reducing the guide adjustment time.

[0017] The present invention will be further described with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example

[0022] like Figure 1-3 As shown, the guide structure of the green and environmentally friendly Z-shaped asymmetric steel sheet pile continuous rolling mill corresponds to the continuous rolling mill used to roll asymmetric Z-shaped steel sheet piles. The continuous rolling mill is equipped with upper and lower rollers 1 and 2, and a continuous rolling mill arch 16 corresponding to the upper and lower rollers 1 and 2. The continuous rolling mill, arch, upper and lower rollers, and the upper and lower guides and vertical side guides described below are all existing technologies, and their structures and principles are not further described.

[0023] A guide box is fixedly installed between the inner walls of the archways of the continuous rolling mill. Its two sides are fixed to the inner walls of the opposing archways 16 via telescopic fastening devices. An upper guide beam 9 is provided on the upper portion of the guide box, to which an upper guide 8 is fixedly mounted. A lower guide beam 5 is provided on the lower portion of the guide box, which is fixedly mounted to a lower guide 7. The upper guide corresponds to the upper roll, and the lower guide corresponds to the lower roll. Vertical side guides 6 are installed on both sides of the guide box, with the positions of the vertical side guides 6 corresponding to the edges of the upper and lower rolls.

[0024] The telescopic fastening device includes a movable threaded rod 17 threadedly connected to the side of the guide box, and the outer end of the movable threaded rod 17 is provided with a fastening seat 3. The fastening seat 3 is fastened to the inner wall of the memorial archway under the action of the movable threaded rod.

[0025] Two threaded seats 4 are symmetrically positioned on either side of the guide box. Each seat 4 comprises a body 14 mounted on the side of the guide box. A threaded hole 15 is formed through the body 14, and an internal thread is provided within the threaded hole 15. A movable threaded rod 17 is provided with external threads, which are connected to the internal thread via a threaded connection. When the movable threaded rod rotates, the movement generated by the threads extends or retracts the rod.

[0026] The guide box includes a box body, the bottom of which is provided with a waist-shaped long hole 13 for connection. The box body is provided with a lower guide installation surface 12 corresponding to the lower guide, two side guide installation surfaces 11 corresponding to the two vertical side guides, and two upper guide installation surfaces 10 corresponding to the left and right upper guides.

[0027] This invention utilizes a guide box structure to secure all guides, forming a single, integrated structure. Compared to existing guide fixing methods that directly compress the guides with wedges on the guide beam or weld them to the beam, this significantly improves guide stability, installation and disassembly time, overall guide strength, and ease of axial position adjustment during rolling impacts. This increases effective rolling time, reduces rolling costs, and reduces the workload of on-site maintenance personnel.

[0028] The bottom of the guide box of the present invention is connected to the continuous rolling mill through waist-shaped long holes and bolts. The fine adjustment movement of the entire guide box can be achieved by loosening the bolts, and the fixation of the guide box can be achieved by tightening the bolts.

[0029] The side of the guide box of the present invention is fixed to the inner wall of the continuous rolling mill archway through a retractable movable threaded rod, thereby achieving higher stability and greatly reducing the guide adjustment time.
