Description
Technical field
The utility model relates to a kind of force cell, relates in particular to a kind of sensor that is used to detect the Winder Disk Brake brake positive pressure.
Background technology
Mine hoist is Coal Production " throat ", is directly connected to the life security of absence from work without reason and the safety in production of mine.And the braking ability of detent plays decisive role to the safe and reliable operation of mine hoist.At present, domestic and international mine hoist a kind of disc brake that is built-in with the dish spring of adapted mostly.The size of braking moment is the braking ability of decision detent directly.And braking under the set condition of conditional parameters such as radius, friction factor, braking positive power is a Key Performance Indicator of decision detent braking ability.According to the principle of work of Winder Disk Brake, the spring force that the dish spring produced when brake positive pressure depended primarily on braking.
For a long time, scientific and technical personnel are devoted to explore the online test method and the means of hoister braking device braking moment always both at home and abroad, in the hope of grasping the operating characteristic of brake system better, brake the safe reliability that device moves thereby improve hoister.Measure dish spring spring force size with online acquisition brake positive pressure value through real time direct; And then indirect dynamic ground tracking system kinetic moment, be a kind of through one of method practical application proof, the most effective on-line monitoring Winder Disk Brake braking ability reliably.This is crucial in order to the force transducer of measuring dish spring spring force wherein.Application number is that 200810155642.3 patent " the dish spring abutment sensor that is used for disk brake monitoring brake positive pressure " discloses a kind of resistance strain gauge force transducer of measuring dish spring spring force.As shown in fig. 1, disclosed patent constitutes with a plurality of foil gauges 1 that are located at paired arrangement in the disk body by having the disk body of diameter of bore greater than dish spring snap ring 4 external diameters; Disk body leans on hydraulic cylinder one side end face to be provided with the shoulder of dish spring brake positive pressure P, and disk body leans on dish spring 2 one sides to be provided with stepped inside and outside groove, and outer groove matches with dish spring 2; The inner groovy bottom is taper; A plurality of foil gauges 1 inclination symmetry of arranging in pairs is located in the conical socket, and wherein dish spring abutment sensor is identical with the original dish spring abutment of existing detent installation dimension, during use; The former dish spring abutment of detent is taken off, change the described dish spring abutment of publication sensor into.Sensor must be demarcated before use.Because the singularity of dish spring abutment sensor actual application environment can't be carried out online, on the throne demarcation, has to carry out off-line calibration.This just makes the demarcation link of dish spring abutment sensor extremely crucial.If the consistance during off-line calibration when the stressed position of sensor and mode and practical application is relatively poor, will greatly reduces the actual measurement precision and the accuracy of sensor, even cause the measurement data distortion.Owing to consider the needs of the distortion and the installation of dish spring 2; Ring diameter is often than the big 1 ~ 2mm of maximum outside diameter of dish spring 2 in the dish spring abutment, so the described dish spring 2 of publication will inevitably move down off-centre because of the effect of deadweight after installation; Shown in B part among Fig. 2; The axis that foil gauge 1 occurs does not seriously overlap with the axis of plunger, and there is bigger deviation the actual loading position when causing stressed position and the duty of off-line calibration, the measured value of appreciable impact sensor.
The utility model content
The purpose of the utility model provides a kind of sensor that is used to detect the disc brake brake positive pressure, and the stressed position in the time of can guaranteeing sensor off-line calibration and real work is basic identical, improves the actual measurement precision and the accuracy of sensor.
The utility model adopts following technical proposals:
A kind of sensor that is used to detect the disc brake brake positive pressure; Comprise and have endoporus and diameter of bore circular disk body and a plurality of foil gauges that are located at symmetric offset spread in the disk body greater than dish spring snap ring external diameter; Disk body leans on hydraulic cylinder one side end face to be provided with the shoulder that bears dish spring brake positive pressure; Disk body leans on dish spring one side to be provided with inside and outside groove; Outer groove matches with the dish spring, is evenly distributed with a plurality of circular holes that do not seal along circumference in the outer shroud of the outer groove of said disk body, and flexible circular bar is coaxially set in the circular hole.
Be evenly distributed with 4 to 8 circular holes that do not seal along circumference in the outer shroud of the outer groove of said disk body, Circularhole diameter is 3-5mm, and hole depth is 8-10mm.
The opening surface of said circular hole is inboard to disk body, and the opening angle that do not seal of circular hole is 120 °-180 °.
The circular bar of said elasticity is the circular bar of elasticity that silica gel or fluororubber are processed, and the diameter of the circular bar of elasticity is greater than circular hole aperture 0.2-0.3mm, and length is 8-10mm.
Symmetric offset spread has 8 foil gauges in the said disk body.
8 foil gauge symmetries are obliquely installed the inner groovy bottom at disk body in the said disk body.
The inner groovy of said disk body is tapered, and cone angle is 15 °-20 °.
The utility model is through evenly being provided with a plurality of circular holes that do not seal along circumference in the outer shroud of groove outside disk body; The flexible circular bar that in circular hole, is coaxially set utilizes the circular bar of elasticity with dish spring jack-up, has avoided the dish spring because the effect of conducting oneself with dignity moves down off-centre; Thereby the stressed position when guaranteeing sensor off-line calibration and real work is basic identical; Improve the actual measurement precision and the accuracy of sensor, simple in structure, be easy to realize.
