Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this
The specific embodiment of utility model is described in detail.Many details are explained in the following description in order to abundant
Understand the utility model.But the utility model can be implemented with being much different from other way described herein, this field
Technical staff can do similar improvement without prejudice to the utility model connotation, therefore utility model is not by described below
Specific implementation limitation.
The utility model is described in further detail with reference to the accompanying drawings and examples: a kind of slotting deep quickly inspection of submersed nozzle
Survey device, including positioning plate 1, connecting rod 2, measuring rod 3 and positioning wedged block 4；The top of the positioning plate 1 is connected by connecting rod 2
Connect handle 5；The bottom of the positioning plate 1 is equipped with positioning wedged block 4, and the positioning wedged block 4 is perpendicular to positioning plate 1；And the positioning
1 top surface of plate is equipped with thread groove 6；The measuring rod 3 includes top measuring section 31 and lower section screw thread rod segment 7, the screw thread rod segment 7
Cooperate with thread groove 6 with the entire threaded rod of fixation；The outside of the measuring section 31 is equipped with several discoid thorn pieces 32；The thorn piece
Spacing specification between 32 and adjacent another thorn piece is 0.3cm.And for more convenient and more accurate measurement, also in the positioning
The lower section of plate 1 is fixed with sliding sleeve 10 and sleeve 11；The positioning wedged block 4 passes through sliding sleeve 10, and the end of the positioning wedged block 4 is inserted
Enter in sleeve 11；Spring 12 and towing pad 13 are equipped in the sleeve 11, the end of the positioning wedged block 4 connects traction steel rope of cable
14, the traction steel rope of cable 14 passes through towing pad 13, and the other end of the traction steel rope of cable 14 passes through tow ball 15, and with holding rod 16
Motion end 17 connects, and the holding rod 16 is hinged on 5 lower section of handle；And the periphery of submersed nozzle is cylindrical shape mostly, therefore right
The concave surface 9 by 1 outside of positioning plate answered is designed as and the matched concave surface of cylinder.
In above-mentioned implementation structure, when operation, handle 5 is held, and suitably push down holding rod 16, pushes down the drive of holding rod 16 and lead
Drawing the movement of steel cable 14, traction steel rope of cable 14 pulls positioning wedged block 4, and positioning wedged block 4 retracts to concordant with the lower surface of positioning plate 1 fastly,
Stretching out the about 1-2cm of positioning plate 1, (extension elongation is too long to be will cause when lower section measures submersed nozzle depth, and measuring rod inclination is surveyed
Amount result has large error), then the concave surface 9 of positioning plate 1 is bonded with submersed nozzle periphery, and give one to immersion
Then the power that the formula mouth of a river is drawn close slowly is stretched downwards, until positioning wedged block 4 reaches below submersed nozzle, then unclamp holding rod
16, and mention upwards, check whether correctly it has been stuck in below submersed nozzle；It is of short duration after being stuck in below submersed nozzle
It pauses several seconds, band molten steel contacts sufficiently with measuring rod, then pushes holding rod 16, then whole will take out upwards, and then observe
Molten steel is immersed in the distance of thorn piece 32, then measures, can measure submersed nozzle and be inserted into molten steel face depth below
Degree；And 3 lower end of measuring rod is being related to of being connected through a screw thread, and is easy for integral demounting, the molten steel that measuring rod 3 has solidified is put
It sets below high pressure nozzle, very thin steel layer can be cleaned and be removed, realize recycling；And the place of piece 32 is pierced, it does not enter
Molten steel can be stopped to be immersed in the measuring rod above critical thorn piece to molten steel critical thorn piece bottom surface below, and it is inclined be related to,
Even if molten steel is immersed in critical thorn piece upper surface on a small quantity, and when be not immersed in measuring rod 3, ignore, this phenomenon is
Since the inclination of measuring rod 3 causes.It can quickly be measured by above structure, and structure can be repeated as many times and utilize, and have
Precision is high, interferes molten steel small advantage.
In further implement, fixed block 8, the fixed block 8 are additionally provided between the measuring section 31 and screw thread rod segment 7
Bottom end face is concordant with the top end surface of positioning plate 1.
In said structure, it prevents from being difficult to clean off and entering molten steel in thread groove 6 by being related to fixed block 8, so as not to it is subsequent
There are card plugs when screwing in new measuring rod 3.
And in specific implement, since the thickness of SEN degree of mouth of a river two sides is in 50-80mm or so, positioning wedged block 4
Of length no more than 50mm, only need positioning wedged block 4 that can be stuck on the side wall of the mouth of a river.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
