Description
Technical Field
The utility model belongs to the technical field of a sensor, concretely relates to tension sensor.
Background
The steel wire rope is used as a key component for traction and bearing, is widely applied to the fields of coal mines, metallurgy, high-rise building lifting, transportation, ports, tourism and the like, and plays an important role. Because the steel wire ropes are used under special working conditions, and have high safety factors, the phenomena of overload of the steel wire ropes, tension imbalance among the steel wire ropes, influence on the service life of the steel wire ropes, even severe mechanical accidents such as breakage of the steel wire ropes and the like, and loss of production property are avoided to the utmost extent, so that the tension of the steel wire ropes must be effectively monitored in real time.
At present, the existing tension sensor is complex in installation, small in measuring range, large in installation size, high in cost and poor in measuring precision, so that the requirement of a steel wire rope cannot be met, and the application range of the steel wire rope is greatly limited.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the not enough tension sensor that provides to above-mentioned prior art, its simple structure, the installation is simple, and the replacement is convenient, and the range is wide, and measurement accuracy is high and repeatability is good.
In order to realize the technical purpose, the utility model discloses the technical scheme who takes does:
a tension sensor, wherein: including base, atress wheel, wire rope, first pivot, left leading wheel, resistance strain sensor, second pivot, right leading wheel, third pivot and fixed axle, left leading wheel install on the base through first pivot, the atress wheel install on resistance strain sensor through the third pivot, resistance strain sensor install on the leading flank of base, right leading wheel install on the base through the second pivot, the fixed axle install in the mounting hole on the base, wire rope draw forth from right leading wheel behind left leading wheel and the atress wheel in proper order.
In order to optimize the technical scheme, the specific measures adopted further comprise:
the tension angle of the stress wheel is 2-6 degrees.
The stress wheel, the left guide wheel and the right guide wheel are all made of oil-free self-lubricating cast nylon materials.
The bottom of the resistance strain sensor is provided with a lead-out cable.
In the utility model, the heights between the middle left guide wheel, the middle right guide wheel and the middle stress wheel have a relative displacement value which is not on the same horizontal line; after the steel wire rope passes through the left guide wheel, the stress wheel and the right guide wheel, a tension angle is formed on the stress wheel by the steel wire rope, tension generated by stress of the steel wire rope is reacted on the stress wheel, so that component force is generated and acts on the resistance strain type sensor, and after the component force is measured by the resistance strain type sensor, the tension is reversely deduced.
The utility model has the advantages of following several: the sensor is arranged at the fixed end of the stressed wheel rotating shaft, so that the sensor is simple to install and convenient to replace; the sensor is slightly influenced by the shaft diameter of the rotating shaft of the stress wheel, the range of the manufacturable measuring range is wide, and the size of the sensor is reduced; the force source is relatively stable after being transmitted by the stress wheel and the rotating shaft, so that the measuring precision is high, the repeatability is good, and the lateral force resistance is good.
