Torpedo ladle with mechanical limiting control system

Abstract

A torpedo ladle with a mechanical limiting control system comprises a torpedo ladle body and a ladle body driving device. A vertical limiting device, a left tip-over limiting device and a right tip-over limiting device are arranged at the tail end of a ladle body transmission shaft which is arranged on the end portion of the torpedo ladle body. The vertical limiting device comprises a first mechanical limiting body, a second mechanical limiting body, a first limiting contact and a second limiting contact, wherein the first limiting contact and the second limiting contact correspond to the first mechanical limiting body and the second mechanical limiting body respectively. The first mechanical limiting body and the second mechanical limiting body are respectively arranged on steel plate fixing supports which are arranged outside the ladle body transmission shaft, and the first limiting contact and the second limiting contact are arranged at the tail end of the ladle body transmission shaft. The left tip-over limiting device and the right tip-over limiting device comprise a third mechanical limiting body and a fourth mechanical limiting body. The third mechanical limiting body and the fourth mechanical limiting body are respectively arranged on steel plate fixing supports which are arranged outside the ladle body transmission shaft in the circumferential direction of the transmission shaft, and the included angles between the third mechanical limiting body and the fourth mechanical limiting body, between the first mechanical limiting body and the fourth mechanical limiting body and between the second mechanical limiting body and the third mechanical limiting body are all 120 degrees. The torpedo ladle is accurate in limiting, and accidents are effectively avoided.

Description

technical field [0001] The invention relates to a molten iron transportation device for an ironmaking system, in particular to a torpedo tank with a mechanical limit control system. Background technique [0002] In recent years, with the rapid development of large-scale blast furnaces and converters in the iron and steel industry, higher requirements have been placed on the capacity and thermal insulation performance of molten iron transport containers. In order to meet the requirements of molten iron transportation, the current molten iron transportation containers mostly use torpedo-type torpedo tanks as the molten iron transportation means. Usually, the left and right tilting limits of torpedo tanks used by iron and steel enterprises are mostly controlled by the master controller. Due to the influence of the operating environment of the torpedo tank, the master controller has a very short service life and relatively high maintenance costs. High, poor safety protection pe...
