Abstract
The purpose of this utility model is to provide a kind of tapping machine rock drill protection device, includes opening driver drilling rod, rock drill, and by telescopic joint, described sleeve pipe is provided with circular protection board, and described circular protection board is welded on sleeve pipe for opening driver drilling rod and rock drill；This utility model tapping machine is when high-temperature liquid state slag iron works; liquid metal contacts circular protection board first; thus avoiding liquid metal directly contact tapping machine rock drill sealing gasket; cause sealing gasket and the situation of the direct scaling loss of rock drill; change number of times using rear rock drill sealing gasket to change from original 3 days one, extend to and change for 2 months one.
Description
Technical field
This utility model is related to technical field of metallurgical equipment and in particular to a kind of tapping machine rock drill protection device.
Background technology
It is known that tap hole of blast furnace work under bad environment, Fluid Contacting state slag iron often during opening, lead to tapping machine rock drilling
Secret packing and the frequent scaling loss of rock drill, change tapping machine rock drill sealing gasket and rock drill all can lead to the worn-out wind of blast furnace even to subtract
Wind, impact blast furnace normally produces.
Utility model content
The purpose of this utility model is to provide a kind of tapping machine rock drill protection device, to solve prior art split shed machine
Rock drill sealing gasket and the problem of the frequent scaling loss of rock drill.
For this reason, this utility model adopts the following technical scheme that：A kind of tapping machine rock drill protection device, including opening machine drill
Bar, rock drill, opening driver drilling rod and rock drill pass through telescopic joint, and described sleeve pipe is provided with circular protection board, described circular protect
Backplate is welded on sleeve pipe.
Further, described circle protection board is diameter 150～200mm, the circular steel plate of thickness 5～10mm.
The beneficial effects of the utility model are：When high-temperature liquid state slag iron works, liquid metal contacts circle to tapping machine first
Shape protection board, thus avoiding liquid metal directly contact rock drill sealing gasket, causes sealing gasket and the direct scaling loss of rock drill
Situation, changes number of times using rear rock drill sealing gasket and changed from original 3 days one, extend to and change for 2 months one.
Brief description
Fig. 1 is a kind of tapping machine rock drill protection device structural representation.
In figure：1st, opening driver drilling rod；2nd, rock drill；3rd, sleeve pipe；4th, circular protection board；5th, sealing gasket.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further details.
As shown in figure 1, a kind of tapping machine rock drill protection device, including opening driver drilling rod 1, rock drill 2, opening driver drilling rod
It is connected by sleeve pipe 3 with rock drill, sleeve pipe 3 is provided with circular protection board 4, circular protection board is diameter 150～200mm, thickness 5
The circular steel plate of～10 mm, is welded on sleeve pipe.
When this utility model uses, first circular protection board 4 is welded to the set that opening driver drilling rod 1 is connected with rock drill 2
On pipe 3, then by drilling rod manual link on rock drill, in rotation work, taphole drilling goes out high-temperature liquid state slag iron to rock drill 2,
Fall directly into blast furnace main channel under the stop of circular protection board 4, will not splash on the rock drill 2 and sealing gasket, it is to avoid rock drilling
The problem of the frequent easy scaling loss of the sealing gasket 5 of machine 2.
