The utility model aims to overcome technical difficulties that a prior tension sensor has a complicated structure, is inconvenient in installing and processing and has mechanical errors. Thus, the utility model provides the tension sensor which has a simple structure and high precision, can be installed and processed conveniently and has no mechanical error. The tension sensor includes a cross beam, a loading device, foil gauges and a cable line. It is characterized in that the loading device includes a U-shaped pressing strip and a connection board. An upper end face of the connection board connects with the middle of a bottom face of the cross beam fixedly. The connection board and the cross beam are mutually perpendicular. The U-shaped pressing strip is snapped in the middle of the cross beam and a lower end of the U-shaped pressing strip goes through the connection board. A propelling device is installed on the lower end of the U-shaped pressing strip. Semicircular bosses are arranged on upper end faces of two ends of the cross beam.

Description
Technical field
The utility model relates to a kind of sensor, says more specifically to relate to a kind of tension pick-up.
Background technology
At present, before using wire rope, all need carry out tension test to wire rope, whether the tension force of measuring steel wire conformance with standard; Simultaneously after using, also need carry out regular detection, avoid the accident of outage that in the process of operation, collapses, and the method that generally detects wire rope there are three kinds: the one, by means of staff's eyes the sag of wire rope is observed; Be converted into tension force, the 2nd, rely on sound to judge the tensioning degree of wire rope through hammering, the 3rd, detect through tension pick-up; Because the above two all are that the dependence experience is judged, the result is very inaccurate, though the third accuracy of detection has improved; But, self has defective because designing; Accuracy of detection requirement for present is still not accurate enough, and the Chinese patent notification number is CN2165437Y, and the day for announcing is that the name of the utility model on May 18th, 1994 is called tension pick-up; A pulley is respectively installed in two ends at the beam type resistance strain sensor; The middle part is installed one and can quantitatively be advanced, though the charger formation that adopts the secondary loading to advance, can the error of elimination; But because the deadweight of beam type resistance strain sensor can make wire rope that the distortion of any takes place, and then produce machine error.
Summary of the invention
The purpose of the utility model is to overcome existing tension pick-up complex structure, installs, processes inconvenience, has the technical barrier of machine error; Provide a kind of simple in structure; Installation, easy to process, and eliminated machine error, the tension pick-up that accuracy of detection is high.
The utility model solves through following technical proposals: a kind of tension pick-up; Comprise crossbeam, charger, foil gauge and cable, it is characterized in that described charger comprises U-shaped press strip and web joint; Described web joint upper surface is fixedly connected with crossbeam bottom surface middle; Described web joint is vertical each other with crossbeam, and described U-shaped press strip is connected in the crossbeam middle and web joint has been passed in the lower end, and described U-shaped press strip lower end is equipped with propulsion plant; The upper surface at described crossbeam two ends is equipped with semi-cylindrical hill; Described convexity is provided with gathering sill, and described foil gauge is attached at the both sides, front and back of crossbeam, and described cable is connected with an end of crossbeam.Wire rope is placed on the gathering sill, and the inboard top of the bottom surface of two gathering sills and U-shaped press strip is positioned at same surface level, when propulsion plant is worked; The U-shaped press strip moves downward, and the stretching wire rope bends wire rope; Wire rope passes to power at the two ends of crossbeam simultaneously; Crossbeam is also bent thereupon, racking strain sheet, the size of foil gauge pressurized detected pressures.The utility model is simple in structure, and the influence of crossbeam self gravitation has been got rid of in installation, easy to process, has avoided machine error, has improved accuracy of detection.
As preferably, described propelling equipment comprises pushnut and elastic washer, and described pushnut is threaded with the U-shaped press strip, and described elastic washer is between pushnut and web joint.Through the rotation pushnut U-shaped press strip is moved downward, the compressing wire rope is crooked.
As preferably, described foil gauge has two, and two foil gauges are symmetrical set with respect to the U-shaped press strip.Foil gauge is positioned near the beam deformation amplitude maximum, improves accuracy of detection.
As preferably, described cable is connected with crossbeam through water joint.Water joint plays waterproof and grease proofing effect.
Therefore, a kind of tension pick-up of the utility model possesses following beneficial effect, and 1, simple in structure, install, easy to process, 2, avoided the error brought because of the wire rope distortion that the deadweight of self causes, eliminated machine error, improved accuracy of detection.
