Displacement sensor realizes that roll gap meter follows dummy bar to carry out on-line measurement and calibration, oil cylinder to the roll gap of setting during opening and pouring
Displacement sensor is mounted among clamping cylinder, and is moved with oil cylinder.For tri-joint mechanism formula gap preset structure type
Continuous casting unit fan-shaped section, since the connection of upper and lower frames and clamping cylinder pedestal is articulated structure, upper and lower frames passes through cylinder body
Connection admit of slight swing.Under non-casting condition, there is certain " zigzag " roll gap defect in fan-shaped section, be
The management of cold conditions roll gap brings serious interference, although eliminating most of zigzag defect by online roll gap meter, but still
It is unable to satisfy the control requirement of roll gap precision ± 0.5mm.There is also bulge power and bulge power to cause hingedly for hot roll gap simultaneously
The problems such as influence of the structure interval to roll gap.Actually clamping cylinder articulated structure of cylinder pedestal when pressurizeing load can exist
Gap, to influence true roll gap.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of measurement dresses of continuous casting unit fan-shaped section upper and lower frames displacement

Gap values between rollers, promote the hot roll gap precision of casting machine, and provide more reasonable control mark for online roll gap meter cycle detection precision
It is quasi-.
In order to solve the above technical problems, the measuring device of continuous casting unit fan-shaped section upper and lower frames displacement of the present invention includes sector
Frame and lower frame, upper bed-plate, lower bottom base, upper support bar, lower support bar, pull rod, displacement sensor and obliquity sensor in section,
The upper bed-plate and lower bottom base are respectively arranged on the upper frame and lower frame and are located at same vertical line, the upper support bar top
It is respectively arranged on the upper bed-plate and lower bottom base with lower support bar bottom end, institute's displacement sensors are set to the upper support bar, described
Pull rod both ends are separately connected the displacement induction end of the lower support bar top and displacement sensor, and the obliquity sensor is set to institute
State pull rod surface.
Further, institute's displacement sensors are magnetostrictive displacement sensors, the displacement induction end of institute's displacement sensors
For magnet slide block.
Further, the present apparatus further includes backing plate, and the backing plate is set to the pull rod surface, and the obliquity sensor passes through spiral shell
Bolt is fixed on the backing plate.
Further, the upper support bar and lower support bar are respectively adopted bolt and are fixed on upper bed-plate and lower bottom base, it is described on
Pedestal and lower bottom base, which are respectively adopted, is fixedly welded on the upper frame and lower frame.
Since the measuring device of continuous casting unit fan-shaped section upper and lower frames of the present invention displacement uses above-mentioned technical proposal, the i.e. present apparatus
Upper bed-plate and lower bottom base be respectively arranged on frame and lower frame and be located at same vertical line, upper support bar top and lower support bar
Bottom end is respectively arranged on upper bed-plate and lower bottom base, and displacement sensor is set to upper support bar, and pull rod both ends are separately connected lower support bar top
The displacement induction end at end and displacement sensor, obliquity sensor are set to pull rod surface.The present apparatus realizes the hot condition lower fan of continuous casting
The displacement detecting of shape segment frames vertically and horizontally promotes the hot roll gap precision of casting machine for monitoring true gap values between rollers,
And more reasonable control standard is provided for online roll gap meter cycle detection precision.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is the measuring device schematic diagram of continuous casting unit fan-shaped section upper and lower frames of the present invention displacement.
Specific embodiment
Embodiment is as shown in Figure 1, the measuring device of continuous casting unit fan-shaped section upper and lower frames of the present invention displacement includes fan-shaped section
Upper frame 1 and lower frame 2, upper bed-plate 3, lower bottom base 4, upper support bar 5, lower support bar 6, pull rod 7, displacement sensor 8 and inclination angle
Sensor 9, the upper bed-plate 3 and lower bottom base 4 are respectively arranged on the upper frame 1 and lower frame 2 and are located at same vertical line, described
5 top of upper support bar and 6 bottom end of lower support bar are respectively arranged on the upper bed-plate 3 and lower bottom base 4, and institute's displacement sensors 8 are set to
The upper support bar 5,7 both ends of pull rod are separately connected the displacement induction of 6 top of lower support bar and displacement sensor 8
End, the obliquity sensor 9 are set to 7 surface of pull rod.
Preferably, institute's displacement sensors 8 are magnetostrictive displacement sensors, the displacement induction of institute's displacement sensors 8
End is magnet slide block.
Preferably, the present apparatus further includes backing plate 10, and the backing plate 10 is set to 7 surface of pull rod, the obliquity sensor 9
