Abstract
The utility model relates to a force-measuring sensor, in particular to a sensor for measuring the tension of a wire rope. The sensor comprises an elastic body and a strain blind hole which is arranged on the elastic body, a strain gauge is arranged in the strain blind hole, sealant and a cover plate seal are covered on the strain blind hole, a protrusion is arranged in the lateral middle position of the upper part of the elastic body, press blocks which protrude the elastic body are respectively arranged at both ends of the elastic body, and wire rope penetrating openings are respectively arranged between the two press blocks and the elastic body. When in installation, the wire rope penetrates on the two wire rope penetrating openings, the middle part of the wire rope is jacked up through the protrusion, the wire rope is not extruded, and the potential safety hazard is ensured not to occur.
Description
Technical field
The utility model relates to force cell.
Background technology
Port and pier, shipyard, mine and construction and installation building site are being extensive use of various hoisting machineries.Fixed, removable rotary crane, arm crane, truck-mounted crane etc. are wherein modal hoisting devices.In order to give full play to the ability of crane, and prevent the serious consequence that produces just in case surpass allowable load again, just must be on hoisting line pass line tension force force cell so that in time detect the wire rope hoisting weight, reach overload warning.
Existing wire rope sensor is because left and right sides cushion block is fixed with elastic body by welding or screw with elastic body, and the easy when mounted extruded cords rope of the briquetting of centre causes potential safety hazard.In addition, because cushion block and briquetting all are fixed, and wire rope is in the distortion of stressed back, stress point changes, and influences measuring accuracy in use.
Summary of the invention
In order to solve the technical matters that there is potential safety hazard in above-mentioned wire rope sensor, the purpose of this utility model provides a kind of high-precision test wire rope hoisting weight or is used for the sensor of overload warning.Further, the utility model has also improved the measuring accuracy of sensor.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of sensor of testing steel wire rope tension, this sensor comprises elastic body and is arranged on strain blind hole on the elastic body, be provided with foil gauge in the strain blind hole, cover fluid sealant and cover plate for sealing on the strain blind hole, elastomeric upper lateral centre position is provided with projection, elastomeric two ends are respectively equipped with protrudes the briquetting that elastic body is provided with, and is respectively equipped with the steel wire penetrating mouth between two briquettings and the elastic body.
As preferably, be provided with " U " type groove in the middle of the described briquetting bottom, elastomeric two ends also are respectively equipped with " U " type groove, and briquetting is arranged on elastomeric two ends by bolt, and described steel wire penetrating interruption-forming is between briquetting and elastic body.
As preferred again, described two steel wire penetrating mouths are downward-sloping setting respectively toward two ends.
As an alternative, described briquetting is made of two blocks of side plates and a top board, and two blocks of side plates of briquetting are arranged on the elastic body by the power transmission bolt respectively, and described steel wire penetrating mouth is arranged between the top board and elastic body of two briquettings.
As preferably, above-mentioned projection is a circular arc, is provided with deep-slotted chip breaker on the lower elastomers of steel wire penetrating mouth, is provided with arc convex on the top board of the top of steel wire penetrating mouth.
As preferably, between axial direction power transmission bolt and briquetting, be provided with the gap.
The utility model is owing to adopted above-mentioned technical scheme, wire rope to be through on two steel wire penetrating mouths, and the wire rope middle part is by protruding jack-up, and wire rope all is not squeezed when mounted, guarantees can not cause potential safety hazard.The utility model also can be provided with the gap between axial direction power transmission bolt and briquetting in addition, therefore the left and right sides briquetting of sensor is movable in small angle range, briquetting is used in masterpiece on the power transmission bolt, by the power transmission bolt power is passed to elastic body, even wire rope deforms, the power that also guaranteed is on the elastic body of vertical effect, has guaranteed measuring accuracy.
