Description
Technical field
The present invention relates to steel rail rolling apparatus field, especially a kind of rolling mill roll position detecting system.
Background technology
Because in the operation of rolling, there is axial float in the asymmetry of shape of rolling piece, rolling mill roll, with only steel during mistake steel
When axial float gap it is larger, axial float testing conditions when static are good, can be realized by simple method.But during dynamic
Roll axial float value is influenceed to be difficult to measure by temperature, roll cooling water, dust, vibrations, larger axial force.Axial direction can not be known
In the case of play, roller gap adjustment can only be carried out by rule of thumb, cause largely to adjust the defective products caused.Meanwhile, roll up and down
Roller there is also the change of position when crossing steel, due to being dynamic change, it is impossible to which the displacement transducer by milling train itself is accurate
Measurement.It is existing that bearing block axial location is measured come the method for determining the position of roll dynamic axial using dynamic, it can not only supervise
The dynamic position change of up-down rollers is surveyed, also there is following problem：First, the error that bearing block and roll seam are produced can not be arranged
Remove；2nd, the gap between bearing block and mill housing can not be excluded, because the maximum measurement error of the abrasion of memorial archway wearing plate reaches
5mm is arrived.
Existing detection method, is the end by the way that measurement probe to be placed on to measured roll, when monitoring roll crosses steel
The change of axial displacement, is then sent to display by displacement transducer by measured value again and is observed or directly will be by machine
Tool mode is intuitively read measured value amplification on counting scale.But the problem of existing method also has following：First, detection is set
The standby strong point on memorial archway by dust, water smoke etc. influence to install shakiness rock greatly, also result in mounting surface injustice；2nd, detect
The set-up time of equipment is up to 30-50 minutes, influences production efficiency；3rd, the working environment such as dust, water influence equipment detection essence
Degree, also results in the failure of detection device；4th, the dynamic change of top and bottom rolls position can not be monitored.
The content of the invention
The technical problems to be solved by the invention are to provide one kind by optical measurement principle, more accurately realize that milling train rolls
The rolling mill roll position detecting system of roller play monitoring.
The technical solution adopted for the present invention to solve the technical problems is：Rolling mill roll position detecting system, including it is to be checked
The topping roll and bottom roll of survey, including laser monitor device, the termination of same one end of the topping roll and bottom roll are set respectively
Have topping roll cone and bottom roll cone, light curtain that laser monitor device is launched through being provided with topping roll cone and
Form light curtain shadow region after bottom roll cone, the laser monitor device is by monitoring light curtain shadow region and light curtain
Change and realize the monitoring axially changed to topping roll and bottom roll.
Be further, the laser monitor device by light curtain generator and image mechanism into.
It is further that the angular range of the shooting angle between the video camera and light curtain is 30-60 degree.
It is further that the central axis of the topping roll cone and the central axis coaxial of topping roll are arranged.
It is further that the central axis of the bottom roll cone and the central axis coaxial of bottom roll are arranged.
The beneficial effects of the invention are as follows：The present invention cleverly distinguishes in the termination of topping roll and same one end of bottom roll first
Topping roll cone and bottom roll cone are set, the light curtain formation light curtain shade for then recycling laser monitor device to launch
Region, so that detection benchmark that is sensitive and accurate and can monitoring is constructed, on this basis, by the detection of laser monitor device,
The accurate picture of topping roll and bottom roll play is obtained, so as to realize in real time and accurately control, it is ensured that production is smoothly entered
OK.Present invention is particularly suitable for accurate control topping roll and bottom roll operating condition is needed, so as to realize the production efficiently produced
Occasion.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Marked in figure：Topping roll 1, topping roll cone 11, bottom roll 2, bottom roll cone 21, light curtain generator 3,
Light curtain 31, light curtain shadow region 32, video camera 4.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
Rolling mill roll position detecting system as shown in Figure 1, including topping roll 1 and bottom roll 2 to be detected, including laser
Supervising device, the termination of same one end of the topping roll 1 and bottom roll 2 is respectively arranged with topping roll cone 11 and bottom roll circle
Cone 21, the light curtain 31 that laser monitor device is launched shape after being provided with topping roll cone 11 and bottom roll cone 21
Into light curtain shadow region 32, the laser monitor device is realized by monitoring the change of light curtain shadow region 32 and light curtain 31
The monitoring axially changed to topping roll 1 and bottom roll 2.
The present invention can change original of the laser rays in the length of cone glazed thread using roll when bearing is to play
Reason, by calculating the change of laser arc length, to calculate the size of roll mandrel narrow-necked earthen jar shifting amount.Meanwhile, up-down rollers cone can be measured
Between spacing, so as to detect the dynamic change of roller gap.One ingenious part of present inventive concept is exactly that have selected
Topping roll cone 11 and bottom roll cone 21, can cause light curtain shadow region 32 linear when being moved axially using cone
Change this feature, guarantee is provided for the dynamic monitoring of laser monitor device.In addition, in actual use, it is basic to use step
Suddenly it is such：After related device is installed, first time demarcation is carried out first, topping roll 1 and bottom roll 2 are placed in zero-bit
The light curtain shadow region 32 of state, laser monitor measurement device topping roll cone 11 and each self-forming of bottom roll cone 21
Then the central point of shadow length L0up, L0down and two axles is changed gap values between rollers with being axially worth and surveying respectively apart from S0 by gradient
Corresponding L1up, L1down, S1, and L2up, L2down, S2 etc. are obtained, Axial changes and Lxup, Lxdown are finally respectively calculated
Relation, and roll gap change and Sx relation are calculated, and correcting process is carried out, so that in actual monitored, output is then to be upper
The transition informations such as the centre-to-centre spacing distance of roll 1 and bottom roll 2 and relative axial position.General, the laser monitor device choosing
Select and be made up of light curtain generator 3 and video camera 4.Further, when being monitored using video camera 4, in order to ensure monitoring
The degree of accuracy, the angular range of the shooting angle between preferably described video camera 4 and light curtain 31 is 30-60 degree.
As the key Design of monitoring, preferably by the center of the central axis of the topping roll cone 11 and topping roll 1
Axis coaxle is arranged and the central axis of the bottom roll cone 21 is arranged with the central axis coaxial of bottom roll 2.So as to
When ensureing topping roll 1 and the rotation of bottom roll 2, topping roll cone 11 and bottom roll cone 21 have stable operating condition, from
And ensure being smoothed out for monitoring.
The present invention cleverly set respectively in the termination of topping roll and same one end of bottom roll first topping roll cone and
Bottom roll cone, the light curtain formation light curtain shadow region for then recycling laser monitor device to launch, so as to construct spirit
Detection benchmark that is quick accurate and can monitoring, on this basis, by the detection of laser monitor device, obtains topping roll and bottom roll
The accurate picture of play, so as to realize in real time and accurately control, it is ensured that production is smoothed out.
