Description
Technical Field
The utility model relates to a casting blank length measurement device that uses when carrying out scale cutting to the continuous casting billet belongs to and measures technical field.
Background
In the running process of a slab caster, the length of a casting blank needs to be measured so as to realize the fixed-length cutting of the casting blank. The existing casting blank length measuring device mainly comprises a measuring roller and an encoder which are not driven by a motor, and a roller shaft of the measuring roller is coaxially connected with a measuring shaft of the encoder through a metal connector (also called a coupler). When the device normally works, the measuring roller is lifted and driven along with the casting blank, and the length of the casting blank is measured by the encoder. In the measurement process, the slab must be hugged closely in order to ensure that it follows the slab and rotates and not skid to the measuring roller, because receive high temperature environment's influence for a long time, the condition of slope or deformation often appears in the roller of measuring roller for the measuring shaft of roller and encoder is incomplete coaxial, and then leads to the shaft coupling to damage, and the unable accurate count of encoder seriously influences the normal operating of slab caster. Once the coupler is damaged, only automatic fixed-length cutting can be converted into manual blank cutting, so that the labor intensity of operators is greatly increased, and continuous casting speed reduction or casting stop accidents are easily caused. Therefore, it is necessary to design a highly reliable device for measuring the length of a cast slab.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a casting blank length measurement device of high reliability to the drawback of prior art to ensure that slab caster moves smoothly.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a casting blank length measurement device, includes measuring roll, fixing base, hose and encoder in the constitution, the measuring roll leans on the slab, and the roller of measuring roll passes through the bearing and rotates with the fixing base to be connected, is equipped with coaxial connecting axle at the roller tip of measuring roll, the encoder is fixed on the support, and the output lead wire of encoder is connected with slab caster's controller, the both ends of hose are connected with the measuring shaft of connecting axle and encoder respectively.
According to the casting blank length measuring device, the two ends of the hose are respectively sleeved on the connecting shaft and the measuring shaft of the encoder and are fastened through the anchor ears.
In the casting blank length measuring device, the hose is a high-pressure oxygen pipe.
In the casting blank length measuring device, the measuring shaft of the encoder is coaxial with the measuring roller.
The utility model discloses replace traditional shaft coupling with the hose and transmit the moment of torsion, not only can make the measuring spindle and the measuring roller synchronous revolution of encoder, guarantee the measurement accuracy of casting blank length, the roll shaft of measuring roller appears inclining or warp moreover and can not lead to the fact the influence to measuring device's operation. The device simple structure, low cost, operation are reliable and the commonality is strong, can realize the accurate measurement of continuous casting billet size, improve slab cutting quality and cutting efficiency, ensure slab caster and move smoothly.

Detailed Description
The utility model provides a casting blank length measurement device, the device simple structure, the investment is little with the maintenance work load, and operational reliability is high, and long service life can realize the accurate measurement of continuous casting billet cutting scaling-off.
Referring to fig. 1 and 2, the utility model discloses mainly include measuring roller 1, fixing base 3, hose 4, encoder 5, support 6, two staple bolts 7 and connecting axle 9. Roller 2 of measuring roller 1 rotates with fixing base 3 through the bearing to be connected, fixes and is connected through the one end of staple bolt 7 with hose 4 at the connecting axle 9 of 2 tip of roller, and the other end of hose 4 is connected with encoder 5's measuring shaft 8 through another staple bolt 7, and encoder 5 fixes on support 6, and encoder 5's output lead 10 is connected with slab caster's PLC controller.
Because the running speed of the measuring roller is relatively slow and is 1.8m/min at the fastest speed, the hose 4 is used as a connecting piece, the influence of non-coaxial and vibration of the measuring roller 1 and the encoder 5 can be eliminated, and the accurate measurement of the length of the plate blank is realized.
The hose 4 is made of a high-pressure oxygen pipe, has certain flexibility, can ensure that the roll shaft 2 and the measuring shaft 8 of the encoder 5 are completely synchronous after being fastened by the hoop 7, and is not easy to damage; the problem that the coupler is easy to damage when hard connection is used in the past is thoroughly solved. After the coupler is replaced by the hose, the coupler is replaced once every year during overhaul. The manpower and material resources are saved, and the accuracy of cutting and sizing is improved.
The utility model discloses a working method as follows: in the casting process, the measuring roller 1 rises and is tightly attached to the lower surface of a plate blank and rotates synchronously with the plate blank, the roller shaft 2 of the measuring roller 1 drives the measuring shaft 8 of the encoder to rotate synchronously through the hose 4, the distance of the plate blank moving is calculated through the encoder, and finally the plate blank is cut according to the set fixed length.
