Abstract
The utility model discloses a continuous casting machine casting-roll gap instrument disposed on the side portion of a chain link of a dummy ingot chain. The instrument comprises a bearing seat, a transmission mechanism, a contact swing mechanism and a measuring mechanism, wherein the transmission mechanism is disposed on the bearing seat, the contact swing mechanism and the measuring mechanism are respectively arranged on the transmission mechanism, and the contact swing mechanism is in mutual linkage with the measuring mechanism. During casting, the instrument slides along with the dummy ingot chain, measuring swing arms are opened under action of spring tension so as to drive contact swing arms to open and to lead contact blocks to respectively contact with an upper casting roll and a lower casting roll, thereby forming continuous angle variation, and simultaneously, displacement variation measured by a displacement transducer reflects an actual roll gap valve. Therefore, the instrument not only increases measurement precision and actuality, but also increases measuring efficiency, and is favorable of increasing productivity of casting machines.
Description
Technical field
The utility model relates to the roll gap checkout gear, more particularly, relates to a kind of conticaster casting roller gap instrument.
Background technology
Conticaster all casting rollers on metallurgical passage arrange in pairs that all the roller footpath and the centre-to-centre spacing of every pair of casting roller has determined every pair of corresponding gap values between rollers of casting roller.In whole metallurgical passage, from the crystallizer end opening, the gap values between rollers of every pair of casting roller all needs to determine according to the technological parameter of casting machine, and each gap values between rollers to the casting roller after determining should keep stablizing, accurately, accuracy error must be controlled in the 0.5mm, otherwise easily produces the accidents such as base, bleed-out that stagnate.At present, adopt dummy ingot hair style roll gap meter to come the casting roller gap is measured usually.But, for actual big production of continuous casting, adopt this type of roll gap meter whenever to carry out a roll gap circulation and measure, need 60min at least, and the cast of can not following up simultaneously.Yet in process of production, the frequent roll gap drift of casting machine requires operating personnel frequently to measure roll gap again.So this and asynchronous roll gap measurement of cast has had a strong impact on the performance of casting machine production capacity, and can't satisfy the demand of on-the-spot actual production, cause actual roll gap deviation to tend to surpass prescribed limit, there is serious accident potential.
The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of conticaster casting roller gap instrument, and this roll gap meter can be measured roll gap in casting process synchronously, helps improving the accuracy of measurement.
For achieving the above object, the utility model adopts following technical scheme:
This conticaster casting roller gap instrument is located at dummy bar chain chain link sidepiece, comprise bearing block, transmission mechanism, contact swing mechanism and measuring mechanism, transmission mechanism is located on the bearing block, contact swing mechanism and measuring mechanism are located on the transmission mechanism respectively, and contact swing mechanism and the mutual interlock of measuring mechanism.
Described transmission mechanism comprises can counterrotating rotating shaft and rotating cylinder, and rotating cylinder is sheathed in the rotating shaft.
Described contact swing mechanism comprises upper and lower contact swing arm, on contact swing arm one end and rotating shaft is fixed, the other end is provided with contact block; Under contact swing arm one end and rotating cylinder is fixed, the other end is provided with down contact block.
Described measuring mechanism comprises upper and lower measurement swing arm, spring and displacement transducer, on measure swing arm one end and rotating shaft is fixed, following measurement swing arm one end and rotating cylinder are fixed, spring is located at and displacement transducer is connected at respectively between the upper and lower measurement swing arm.
The linear variable differential transformer (LVDT) formula displacement transducer of described displacement transducer for being connected with power supply.
Described measuring mechanism also is covered with seal box outward.
In technique scheme, conticaster casting roller gap instrument of the present utility model is located at dummy bar chain chain link sidepiece, comprise bearing block, transmission mechanism, contact swing mechanism and measuring mechanism, transmission mechanism is located on the bearing block, contact swing mechanism and measuring mechanism are located on the transmission mechanism respectively, and contact swing mechanism and the mutual interlock of measuring mechanism.When cast, roll gap meter slides with dummy bar chain, being subjected to the spring tension effect to measure swing arm opens, and drive the contact swing arm and open, contact block is contacted with casting roller up and down respectively, form continuous angle variable quantity, the displacement variable that this moment, displacement transducer recorded has promptly reflected actual gap values between rollers, therefore not only improve accuracy and the authenticity measured, but also improved measurement efficient, helped increasing the production capacity of casting machine.
