Tension force easily change to produce pine or the problem of tension, this superconductivity that may result in superconducting tape is damaged
The problem of bad or measurement result is inaccurate.
Utility model content
The purpose of this utility model is to provide a kind of strap tension adjusting means, and it can be to the initial tension size of band
It is adjusted, and the phenomenon of band pine or tension excessively can be monitored in band traveling process.
To achieve the above object, the technical solution of the utility model is：A kind of strap tension adjusting means, including loosening and tightening wheel
Assembly, sliding block, fixed seat and push rod, elastic wheel assembly are connected as one with sliding block, and chute is provided with inside fixed seat, and sliding block is slided
It is arranged in chute and elastic wheel assembly can be driven to move, spring is placed with the side of sliding block in chute, push rod one end is stretched
Enter the Roof connected in chute and by its end in one end of spring, its other end is resisted against on sliding block after spring is compressed
So that the band being stretched on elastic wheel assembly has initial tension, the length of chute is stretched into by adjusting push rod and is adjusted
Initial position of the sliding block in chute and then the initial tension size to adjust band, the side of the external fixed seat of chute is set
There is induction installation, induction installation is included on the magnetic switch I and magnetic switch II set respectively close to chute end positions, sliding block
Provided with magnet ring, in band traveling process sliding block to chute one end slide when, the magnetic switch of chute respective end perceives magnetic
Ring is close and then sends the signal of band pine or tension excessively.
Further, the chute is set through the both ends of the surface of fixed seat, and chute end cap is fixed with fixed seat end face,
A push rod bearing is relatively set with fixed seat other end, push rod one end is passed through after the screwed hole set on push rod bearing from solid
Reservation one end is stretched into chute, and the shaft of push rod coordinates with the screwed hole screw thread.
Beneficial effect：The utility model can by adjust push rod stretch into the length of chute come adjusting slider in chute just
Beginning position, and then realize the purpose of regulation band initial tension size, and push rod length easily adjusts, and fine adjustment function can be achieved.This
Utility model can send pine or the tension signal excessively of band in band traveling process by detecting the moving direction of sliding block,
So as to play a part of protecting the superconductivity of superconducting tape without damage and improve measurement result accuracy.
