A hot metal ladle capping device installed on a hot metal tank car

Abstract

The invention relates to a ladle covering-uncovering device installed on a molten iron tank truck. The device is symmetrically installed on the molten iron tank truck by taking the axis of a ladle asa centre. In the device, each of a transmission shaft rotary arm mechanism and a support shaft rotary arm mechanism is of a rectangular border structure, and in the device, an electric-hydraulic pushrod mechanism comprises a motor, a hydraulic oil cylinder and a piston rod, and the head part of the piston rod is hinged to a force arm in the transmission shaft rotary arm mechanism; ladle half-covers are hinged to a transmission shaft rotary arm and a support shaft rotary arm, the transmission shaft rotary arm mechanism and the support shaft rotary arm mechanism are driven to swing by the electric-hydraulic push rod mechanism, the ladle half-covers and the molten iron tank truck keep a parallel state in a covering-uncovering process, and the two ladle half-covers are closed up towards the middle of the ladle from the two sides and spliced to form a complete ladle cover covering the top of the ladle during covering; and the device is further provided with an oil cylinder jacking mechanism used for opening the ladle half-covers in the case that control is failed, so that an accident is avoided. The device is simple in structure, reasonable in design and convenient to operate, and realizes the heat insulation and safety of the ladle in a whole transport process.

Description

technical field The invention relates to a ladle capping device installed on a molten iron tank car, in particular to a device that uses the reciprocating motion of an electro-hydraulic push rod mechanism to drive a transmission shaft rotating arm mechanism and a supporting shaft rotating arm mechanism to complete ladle Add a device for uncovering action. Background technique At present, the hot metal tanker has problems such as long dispatching time on the railway transportation line, large heat loss of the exposed empty ladle and heavy ladle, and low safety during the operation of the ladle. Especially in some old iron and steel plants, the distance between the steelmaking workshop and the blast furnace is relatively long, and the molten iron tanker consists of maintenance workshop-taphole-desulphurization workshop-steelmaking workshop-maintenance workshop, and the entire operation time is more than 8 hours. The temperature drop of the molten iron ladle while waiting can ...

AI Technical Summary

Problems solved by technology

The disadvantages of this device are: 1. The molten iron ladle cover cannot always be kept parallel to the molten iron tank car during the process of adding and uncovering the cover, so the half cover of the molten iron ladle needs a large operating space during the process of adding and uncovering the cover, which makes the device less affected by the site. The short working space is limited and cannot be used; 2. The running track of the ladle cover is affected by many factors during the process of removing the cover. When the equipment is manufactured, it needs to be designed reasonably and installed accurately, otherwise the ladle cover will easily collide with the ladle, and then cannot 3. The rocker of the device is connected to the two side walls of the molten iron tank car, which widens the entire molten iron ladle transportation system; 4. The device cannot be removed when the electro-hydraulic control fails, and there are potential safety hazards in production
