Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology, specifically relating to a safety positioning and storage platform for a sector-shaped segment zero segment. Background Technology

[0002] In existing technology, the segment zero of a continuous casting machine is a key core component, located directly below the crystallizer. It serves as a transition area connecting the crystallizer and the subsequent segment. Its spatial position is vertically installed 0-20mm below the crystallizer outlet, connecting the crystallizer foot rollers above and the first segment of the segment below. It constitutes the starting part of the "arc zone" (arc continuous casting machine) or the transition section of the "vertical zone" (vertical continuous casting machine) of the continuous casting machine. In existing technology, the common industry practice for fixing and storing the segment is to erect temporary scaffolding. This structure has the risks of swaying and cumbersome disassembly, and cannot eliminate the risk of the segment tipping over during storage. Furthermore, it cannot guarantee the possibility of operators falling during operation.

[0003] In view of the above factors, a safe positioning and storage platform for the sector segment zero segment is provided to ensure stable storage of equipment and provide support for personnel fall protection. Utility Model Content

[0004] The purpose of this utility model is to provide a safe positioning and storage platform for sector-shaped segments to solve the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved through the following technical solution: a safe positioning and storage platform for a sector segment zero segment, including a platform body, wherein the platform body is formed by welding HW200×200H steel to form a main frame, an extension base is welded to the bottom of the main frame, and six Φ30 mm anchor bolt holes are symmetrically arranged on the extension base;

[0006] The main body of the platform is an open structure. The main body of the platform is symmetrically welded with diagonal bracing steel plates on both sides. The diagonal bracing steel plates are at a 45° angle to the ground. The bottom of the diagonal bracing steel plates is welded to the extended base.

[0007] A movable platform is provided on the extended base, and the movable platform can slide along the extended base.

[0008] Furthermore, the bottom of the movable platform is connected to a slide rail located on the end face of the extended base via rollers, and the zero-segment positioning frame is detachably connected to the movable platform.

[0009] The outer ends of the main body of the platform are engaged with positioning rails, and the movable platform can move along the positioning rails. The length of the positioning rails is greater than the length of the main body of the platform.

[0010] Furthermore, the movable platform and the zero-segment positioning frame are detachably connected by bolts.

[0011] Furthermore, the zero-segment positioning platform includes a base frame, on which a support platform is fixedly mounted, and the support platform is composed of several spaced steel structure supports.

[0012] Furthermore, the steel structure support is connected to the base frame by bolts or welding, and the adjacent steel structure supports on the support platform are hollowed out.

[0013] Furthermore, the support platform on the base frame is on the same plane as the steel structure support, and a support plate is fixedly installed at the end of the steel structure support;

[0014] An electric telescopic cylinder is fixedly installed on the support plate. The output end of the electric telescopic cylinder is connected to an L-shaped pressure plate. The support plate has an L-shaped structure and is connected to the steel structure bracket by plugging in and fixed with bolts.

[0015] Furthermore, working platforms are provided on both sides of the main body of the platform, and the working platforms are located on the top of the main body of the platform. Two platform supports are welded to one side of the top of the frame of the main body of the platform. The supports are equipped with M36 adjusting bolts and 1200×800 mm hot-dip galvanized steel grating. A 1000 mm high guardrail is provided on the edge of the platform support.

[0016] Furthermore, a ladder is connected to the main body of the platform. The ladder is made of 50×5 flat steel steps with a spacing of 300 mm. The ladder is welded to the main body of the platform and connected to the working platform.

[0017] Furthermore, the main body of the platform (1) is equipped with a safety hanging point (15) by welding. The safety hanging point is made of L75×75×6 angle steel. The angle steel is cut into 300 mm long sections, and a Φ20 mm through hole is drilled in the center of the vertical surface of the angle steel. The angle steel is then welded to the non-operating platform side column of the main body of the platform.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model is equipped with a fall protection structure. An L75×75 angle steel is welded to the opposite side of the work platform. A Φ20 mm round hole is opened on the vertical surface of the angle steel as a safety belt attachment point. The center of the attachment point is 400 mm away from the edge of the platform, and the load-bearing design value is ≥22kN (compliant with GB 6095-2021 standard).

[0020] The main body of this utility model is equipped with an anti-slip ladder with a step spacing of 300 mm. 1.2-meter-high guardrails are fixed on both sides. A working platform (single size 1200×800 mm) is set on the top of the main body of the platform. The bottom of the working platform is equipped with a grid anti-slip plate.

[0021] This utility model establishes a three-level protection structure consisting of a ladder (passage), a platform (working surface), and an anchor point (fall protection). The anchor point is 1.2 meters away from the platform to ensure the effective protection range of the safety rope.

[0022] This invention can eliminate the risk of tipping over during zero-section storage (overturning resistance coefficient ≥2.5) and ensure 100% fall protection for operators during hook-up operations. Attached Figure Description

[0034] The main body 1 of the platform is an open structure. The main body 1 of the platform is symmetrically welded with diagonal bracing steel plates 3 on both sides. The diagonal bracing steel plates 3 form a 45° angle with the ground. The bottom of the diagonal bracing steel plates 3 is welded to the extended base 2.

[0035] The extended base 2 is provided with a movable platform 4, which can slide along the extended base 2.

[0036] The bottom of the movable platform 4 is connected to the slide rail located on the end face of the extended base via rollers, and the zero-segment positioning frame 5 is detachably connected to the movable platform 4.

[0037] One or both ends of the outer side of the platform body 1 are engaged with the positioning rail 6, and the movable platform 4 can move along the positioning rail 6. The length of the positioning rail 6 is greater than the length of the platform body 1.

[0038] One end of the positioning track 6 is in contact with the main body 1 of the platform, and the positioning track 6 is fixed to the installation position of the main body of the platform by bolts.

[0039] The height of the positioning track 6 (the positioning track is set on the base base, and the base base has positioning holes for positioning and installation) is the same as the height of the slide on the end face of the extension base.

[0040] When in use, the zero end placed inside the main body of the platform can be slid out from the outside of the main body of the platform via the movable platform to the positioning track 6 for hoisting.
