Abstract
It the utility model is related to a kind of vertical round billet continuous casting machine strand length-measuring appliance, the bearing block set including movable support, on the movable support and the measurement roller installed on the bearing block, the measurement roller is cylinder, one end of the measurement roller is provided with least one encoder, the movable support connection liquid cylinder pressure, the hydraulic cylinder is installed on firm banking, and the hydraulic cylinder can be manipulated the measurement roller by movable support and is moved forward and backward.When the measuring device works, the contact site for measuring roller and strand is same diameter, even if the contact position for measuring roller and strand deviates roll surface center, its strand length measured will not produce relatively large deviation, prevent the error that concave curved surface roller produces measurement, improve the precision of Length-fixing cutting.
Description
Technical field
The utility model belongs to metal continuous casting technology field, more particularly to the vertical circle that a kind of strand Length-fixing cutting precision is high
Billet continuous casting machine strand length-measuring appliance.
Background technology
In strand production, the strand that conticaster is produced must cut strand according to scale plan by flame cutting machine
As the strand with corresponding cut lengths, and the strand is processed as the blank of next procedure, the cutting of strand
Precision is by the lumber recovery of direct relation whole production line.The strand length measurement method that current vertical round billet continuous casting machine uses is arteries and veins
Encoder length-measuring method is rushed, is changed the amount of spin of driven roller by the pulse coder installed in the servomotor of continuous caster driving roller
Into output of pulse signal, calculating processing is then carried out by PLC, draws position of the strand in vertical casting machine, and control with this
Strand Length-fixing cutting length.But since the driven roller of vertical round billet continuous casting machine is concave curved surface roller, its roll surface and circular strand
Contact position can not accurately be in roll surface center, i.e., at the minimum diameter of concave curved surface roller, therefore by the rotation of driven roller
Measure the strand length that is calculated and be consistently less than strand physical length, it is low to thereby result in strand Length-fixing cutting precision, actual production
In every time the actual Length-fixing cutting length of strand exceed scale projected length more than 2%, influencing vertical round billet continuous casting machine all the time just
Often production.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of high vertical of Length-fixing cutting precision
Round billet continuous casting machine strand length-measuring appliance.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of vertical round billet continuous casting machine strand length-measuring appliance, including movable support, set on the movable support
Bearing block and the measurement roller installed on the bearing block, the measurement roller be cylinder, set at the both ends of the measurement roller
At least one encoder, the movable support connection liquid cylinder pressure are equipped with, the hydraulic cylinder is installed on firm banking, the hydraulic pressure
Cylinder can be manipulated the measurement roller by movable support and is moved forward and backward.
Guide sleeve that the device also includes setting on the movable support, be connected with the both ends of the guide sleeve respectively
First fixing bracket and the second fixing bracket, the guide sleeve, first fixing bracket, the common structure of the second fixing bracket
Into the telescopic chute of the movable support.
Measurement roller, the bearing block and the encoder are both provided with water-cooling channel.
The utility model has the positive effect that：
The utility model is using cylinder measurement roller, when which works, measurement roller with strand is all possible connects
Contact portion position is same diameter, even if the contact position of measurement roller and strand deviates roll surface center, its strand length measured
Relatively large deviation will not be produced, the actual Length-fixing cutting length variation of each strand is no more than scale projected length in actual production
0.5%, eliminate the relatively large deviation that driven roller measurement produces, improve the precision of Length-fixing cutting.
Brief description of the drawings

Embodiment
Below with reference to the accompanying drawings elaborate to technical solutions of the utility model.
As shown in Figure 1, it is the structure diagram of the vertical round billet continuous casting machine strand length-measuring appliance of the utility model, bag
Movable support 3, the bearing block 2 set on the movable support 3 and the measurement roller 1 installed on the bearing block 2 are included, it is described
Roller 1 is measured as cylinder；One end of the measurement roller 1 is provided with least one encoder 4, the encoder 4 will measure roller 1
Amount of spin be changed into output of pulse signal, calculating processing is then carried out by PLC, draws position of the strand in vertical casting machine
Put, and strand Length-fixing cutting length is controlled with this；3 connection liquid cylinder pressure 7 of movable support, the hydraulic cylinder 7, which is installed on, to be fixed
On base 6, the hydraulic cylinder 7 can be manipulated the measurement roller 1 by movable support 3 and is moved forward and backward, strand linear measure longimetry
When device works, the measurement roller 1 is promoted by the hydraulic cylinder 7 and is close to strand, and the frictional force measured between roller and strand makes
It is rotated synchronously with strand；The device also includes the two of the guide sleeve 5 and guide sleeve 5 set on the movable support 3
Hold the first fixing bracket 8 and the second fixing bracket 9 that connect respectively, the guide sleeve 5, first fixing bracket 8, described the
Two fixing brackets 9 collectively form the telescopic chute of the movable support 3, with this come to the telescopic slide of the movable support 3 into
Row is spacing；Measurement roller 1, the bearing block 2 and the encoder 4 are both provided with water-cooling channel, thereby protect and are given birth in continuous casting
Produce the parts of rapid wear under hot environment.
As shown in Figure 2, knot when being the vertical round billet continuous casting machine strand length-measuring appliance Length-fixing cutting of the utility model
Structure schematic diagram, the operation principle of the measuring device are as follows：
The measuring device is installed on the position between flame cutting machine 12 and continuous caster driving roller 10, when 11 head of strand
After the measuring device, hydraulic cylinder 7 by promoting movable support 3 measurement roller 1 is close on strand 11, with strand 11 to
Lower movement, measurement roller 1 rotate synchronously under the action of frictional force, measure 4 output pulse signal of encoder installed on roller 1, PLC
The pulse signal and the diameter calculation of measurement roller 1 exported according to encoder 4 goes out the length of strand 1, and is used as scale using this length
Cutting Length, realizes high-precision Length-fixing cutting.
