Detailed description of the invention
Fig. 1 is the overall structure diagram of specific embodiment of the present invention；
Fig. 2 is specific embodiment of the present invention schematic diagram of substrate structure.
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.
With reference to the accompanying drawing 1 and attached drawing 2 and embodiment the utility model is described in further detail: a kind of submersed nozzle pair
Middle locator, it is characterised in that: including substrate 1, adjusting rod 2, fixed link 7, centering screw stem 3 and mouth of a river centering head 4；The substrate
1 upper end is equipped at least two centering screw stems 3, and 3 top surface of centering screw stem is equipped with fixing head 5, the top of the fixing head 5
Face is equipped with threaded rod A6, is screwed mouth of a river centering head 4 by threaded rod A6；The bottom of the substrate 1 respectively with adjusting rod 2 and
Fixed link 7 is welded as a whole, and the side of the substrate 1 is additionally provided with horizontal ruler 16；The lower end of the adjusting rod 2 has thread segment 8,
Screw shell 10 at the top of the thread segment 8 and bottom plate A9 cooperates, and the upper end of the screw shell 10 is equipped with to be cooperated with thread segment 8
Nut 11, the lower section of the bottom plate A9 and bottom plate B14 are equipped with traveling wheel 15；The side of the fixed link 7 has location hole 12,
It is connected and fixed by location hole 12 and the bolt 23 in fixes sleeve 13, the bottom of the fixes sleeve 13 and bottom plate B14 are welded
It is integrated；The substrate 1 is equipped with sliding slot 19, and the side of the sliding slot 19 is equipped with several bayonets 20, the ruler of the bayonet 20
It is very little identical as cannulated threaded post 17；And the table top 21 of support cannulated threaded post 17, the centering screw stem 3 are equipped in the bayonet 20
Across cannulated threaded post 17 and 1 lower section of substrate is extended to, and is nested with fastening nut 22 outside to the middle screw rod 3 below substrate 1；Institute
The cannulated threaded post 17 for stating centering screw stem 3 and 1 top surface of substrate cooperates, and is equipped with and adjusts in the upper surface of the cannulated threaded post 17
Nut 18.
In said structure, whole passage is realized by traveling wheel 15, by monolithic push to the centre that need to install the mouth of a river
Packet lower section, the main effect of the present apparatus are that guidance tundish accurately installs brick cup and the mouth of a river, make tundish brick cup dress just, dress it is flat
(centering head brick cup center and vertical), water-coating port in positioning, makes centering head at the mouth of a river center when installing the mouth of a river on this basis
And the mouth of a river is normal thereto, indicates that middle water-coating port installation is centering, otherwise with regard to that need to continue to adjust brick cup position, reaches above-mentioned and want
It asks.Centralizer respectively flow between spacing strictly to be adjusted by middle packet stream spacing parameter, ensure that in this way tundish car and crystallization
After device centering, water-coating port is in crystallizer center in each stream, and after putting on submersed nozzle, submersed nozzle can be also in
Crystallizer center, and submersed nozzle will not deflection.Therefore, by the bayonet 20 of 19 side of sliding slot on substrate 1 come
Cannulated threaded post 17 is supported, centering screw stem 3 screws in cannulated threaded post 17, and the centering screw stem stretched out below cannulated threaded post 17
The tight fastening nut 22 of 3 outward turnings fastens entire middle control threaded post 17；And it is screwed head in the mouth of a river pair in 3 top surface of centering screw stem
4, and therefore most mouths of a river in order to match the mouth of a river, set corresponding for mouth of a river centering head 4 at round, cone or rectangle
Shape；When the mouth of a river, centralizer is installed, and judges entirety whether in level, if not in water by horizontal ruler 16
It is flat, then by adjusting adjusting rod 2 and fixed link 7, Lai Shixian substrate 1 is in level, realizes that multiple mouth of a river centering heads 4 are in water
It is flat.Since mouth of a river centering head is continuous multiple, and it is adjusted spacing using sliding slot 19 and bayonet 20, utilizes fastening nut
22 are fixed, therefore can determine the spacing between two neighboring centering head by intermediate packet stream spacing parameter, due to needing to pacify
The middle packet of dress installs brick cup not yet, and gap is larger, therefore centering head can carry out brick cup referring next to centering head directly through gap
And the centering installation at the mouth of a river, make the middle packet of water outlet centering qualification.
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.
