Description
Technical Field
The utility model relates to a blast furnace overhauls equipment technical field, specifically is a cover dismounting device in blast furnace tuyere.
Background
When the middle sleeve is replaced during the large and medium maintenance of the blast furnace or when the middle sleeve is damaged during production and needs to be replaced, the maintenance operation method is to pull out the middle sleeve in a mode of impacting a pull rod by using a manually driven sliding hammer; if the method can not take out the middle sleeve, the oxygen burning method is selected to burn out the middle sleeve to reduce the softening volume and then pull out the middle sleeve. The two methods can damage the middle sleeve, so that the middle sleeve cannot be used for the second time, the method needs more manpower (at least 6-7 people), consumes more materials (oxygen lance, coke and oxygen) and time (generally more than 4 hours), and then oxygen burning operation is carried out, so that the large sleeve is easily burnt, the accident is further enlarged, and the economic and manpower losses are caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to effectively detach the blast furnace jacket from the inner part of the large jacket under the condition of protecting the blast furnace jacket.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a blast furnace tuyere middle sleeve dismounting device, which comprises a middle sleeve, a middle sleeve pull rod, a middle sleeve bracket, a counterweight frame and a connecting frame, wherein the top of the middle sleeve pull rod is provided with the middle sleeve; when the middle sleeve is disassembled, two sides of the tail end of the pull rod of the middle sleeve are jacked by the jacks, the jacks are alternately inching to loosen the middle sleeve, and then the jacks are started simultaneously to pull out the middle sleeve to be pulled to the bracket of the middle sleeve;
the connecting frame is fixedly connected with the middle sleeve bracket through a pin shaft, penetrates through the counterweight frame and is welded on the inner side of the counterweight frame, a jack operation box is installed on the counterweight frame, and the jack operation box is connected with a jack through an oil pipe.
Furthermore, the top end and the tail end of the middle sleeve pull rod are respectively provided with a first triangular rib plate and a second triangular rib plate, the triangular rib plates play a role in reinforcing the middle sleeve pull rod, the strength of the middle sleeve pull rod is guaranteed, and meanwhile, the stability of the middle sleeve pull rod is also improved.
Furthermore, two supporting plates are symmetrically arranged above the middle sleeve bracket, and when the middle sleeve is disassembled, the supporting plates are convenient for supporting the middle sleeve.
The utility model has the advantages that: the utility model provides a pair of cover dismounting device in blast furnace tuyere is rational in infrastructure, and easy operation under the condition of protecting the well blast furnace cover, can conveniently tear it out by the inside of big cover, has reduced the labour, has improved labor efficiency.
