Steel slag grating group hoisting lifting type lifting appliance for slag tank

Abstract

The invention discloses a steel slag grating group hoisting lifting type lifting appliance for a slag tank. The lifting appliance comprises a support, wherein the four corners at the bottom of the support are respectively provided with a hollow landing leg post; the bottom of the landing leg post is open; the landing leg post is internally provided with a screw; the bottom of the screw is supported on a screw pedestal; the screw pedestal is connected with the inner wall of the landing leg post through a connection plate; the screw is provided with a sliding block; the sliding block is in threaded connection with the screw; the bottom of the sliding block is hinged with two lifting hooks; the end parts of the lifting hooks can extend out of the landing leg post; the middles of the lifting hooks are provided with inclined long grooves; the inclined long grooves are internally provided with pin rolls; the pin rolls are fixedly connected with the inner walls of the landing leg posts; and the screws in the four landing leg posts are connected with a driving mechanism. The lifting appliance is used for hoisting a grating group by adopting a lifting mode, thereby avoiding the crazing of double-hole bricks at the bottom of the grating group, realizing the safety in hoisting of the grating group, accelerating the speed of hoisting the grating group and improving work efficiency.

Description

technical field [0001] The invention relates to a sling, in particular to a sling for hoisting a steel slag grid group used on a slag tank. Background technique [0002] In the past, the slag produced in the process of iron and steel smelting was usually poured directly into the slag tank, and the slag tank was transported back to the slag treatment point by a tank truck. However, due to the cooling of the steel slag in a short period of time, the temperature drops sharply, and the steel slag is easy to form large slag and iron lumps at the bottom of the tank. This large slag and iron lumps need to be broken into qualified furnace size standards. The broken slag blocks are easy to splash during the crushing process, which is extremely dangerous and causes great pollution to the environment; the lifting and transportation of irregular large slag blocks is dangerous, the daily processing volume is low, and the operating efficiency is not high. [0003] In order to prevent the...

Problems solved by technology

[0004] However, the above-mentioned three-horizontal, three-vertical and six-piece grid has the disadvantage of occupying a large area. For this reason, the Chinese invention patent (patent number: 201020110891.3) discloses a grid device, which is assembled by machine-made double-hole bricks In this way, the dependence on the production site can be reduced, the production water and three wastes can be greatly reduced, and huge environmental and economic benefits can be obtained.

However, in the actual use process, since the grille device is assembled, it is not an integral structure, and the double-hole bricks at the bottom are very easy to break, so it is very inconvenient to hoist. The spreader for hoisting the grid device into the slag tank
