AI Technical Summary

Technical Problem

In the existing technology, the ratchet rack limiting method of the blast furnace body integral pushing device is not stable enough and the construction is complicated. It is prone to breakage due to stress concentration, which affects the pushing stability.

Method used

The track-guided load-bearing platform, through two hydraulic push rods and a swing arm structure, combined with limit rods and deformation rods, realizes the stable movement of the blast furnace body. The extension and retraction of the hydraulic push rods and the locking of the swing arm, together with the elastic deformation rods to provide support, ensure that the slide table slides stably between the limit rods.

Benefits of technology

This improved the stability and ease of construction of the blast furnace body, prevented the limit rod from breaking due to excessive radial force, and achieved efficient overall blast furnace pushing.

Abstract

The utility model relates to the technical field of smelting engineering, and discloses an integral pushing device for a blast furnace body, which comprises a track for guiding and bearing, and a loading platform capable of moving along the track; the power structure comprises a sliding table, hydraulic push rods, a swing arm and a limiting rod, the two rotatable hydraulic push rods are arranged on the same side of the loading table, the hydraulic push rods are fixedly connected with the sliding table, the sliding table is arranged above the track, one side of the sliding table is elastically connected with the swing arm, and the limiting rod for limiting the swing arm is fixedly arranged on one side of the track; when the output shaft of the hydraulic push rod stretches out again, the end of the swing arm is clamped into the thrust notch of the other limiting rod, the swing arm is restrained from moving leftwards, and support is provided for the sliding table; the output shaft of the hydraulic push rod can push the loading table to continue to move rightwards by a certain distance, the overall structure is simple, and use is stable.
