Problems solved by technology

But because the interval between the first platform 5 and the second platform 6 is small, large equipment cannot enter, and the both sides of the ore distributor 4 are also provided with obstacles 7, 8, and the bellows 3 and the flow valve 2 can only The lower height is transported outwards, so at present, only manpower can be used for disassembly and handling, which is labor-intensive, long construction time, low work efficiency, and may affect the production schedule

Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as figure 2 As shown, the disassembly and reversing trolley includes an upper trolley 10 and a lower trolley 20, the upper trolley 10 is located above the lower trolley 20, and the lower trolley 20 is detachably connected to the upper trolley 10 by bolts. The upper trolley 10 is provided with two supporting rods 11 arranged in parallel. The supporting rods 11 are provided with bellows flange surface fixing holes 12. The bellows flange surface fixing holes 12 are connected with the bellows flange surface of the COREX-C3000 shaft furnace corresponding to the threaded holes on the

[0021] Such as image 3 As shown, the upper trolley 10 includes a closed upper frame body, which is composed of four upper frame baffles 14, 15, 16, 17 connected in sequence, and an upward inclined support is provided between the upper frame baffle...

Abstract

The invention discloses a dismounting and transporting trolley comprising an upper trolley and a lower trolley. The upper trolley is located above the lower trolley and comprises a closed upper frame, roller wheels are arranged at the bottom of the upper frame, and the upper frame is also provided with two support bars arranged in parallel; the lower trolley comprises a lower frame with an opening at one end, the roller wheels are arranged at the bottom of the lower frame, and the lower frame is detachably connected to the upper frame. The dismounting and transporting trolley has simple structure and convenient operation, the dismounting and the transporting of a material flow valve and a corrugated pipe in a COREX (Iron Making By Smelting Reduction)-C3000 shaft furnace can be quickly realized, the labor intensity of an operator is reduced, the construction time is shortened, the replacing speed of an ore charge distributor is quickened and the working efficiency is improved.

Description

technical field [0001] The invention relates to a dismantling and reversing trolley, in particular to a dismantling and reversing trolley for a COREX-C3000 shaft furnace upper material flow valve and bellows. Background technique [0002] COREX is a smelting reduction ironmaking process developed by VAI that uses lump ore or pellets as raw material and non-coking coal as reducing agent and fuel. COREX-C3000 shaft furnace is currently a very advanced and environmentally friendly iron-making shaft furnace. There is an ore distributor mechanism inside it. The ore distributor mechanism can carry out dynamic ore distribution in the furnace. Its installation structure is as follows: figure 1 As shown, the ore distributor 4 is located below the feeding tank 1 , the feeding tank 1 is connected to the ore distributor 4 through the flow valve 2 and the bellows 3 , and the ore distributor 4 is located between the first platform 5 and the second platform 6 . This ore distributor 4 will...
