Abstract
The utility model provides a strain type two-way slope sensor, which mainly comprises a plurality of strain gauges, a bridge circuit comprising the strain gauges, a heavy ball, a plurality of flexible connectors, a plurality of elastic components, a support spherical crown and a base. The elastic components are fixed on the base, each two opposite elastic components form a group, the heavy ball is connected with the elastic components through the flexible connectors, and the strain gauges are respectively bonded to the sides of the elastic components facing the heavy ball and the sides of the elastic components away from the heavy ball along the vertical direction; and the support spherical crown is fixedly arranged at the center of the base, and the heavy ball is arranged at the top of the support spherical crown. The strain type two-way slope sensor has a simple and reasonable structure, is easy to promote and use, can be widely applied in various types of engineering machinery, and is particularly suitable for the working environment of large excavators.
Description
Technical field
The utility model belongs to resistance sensor, is specifically related to a kind of two-way Slope Transducer of strain-type that can be used for the large-scale mine excavator.
Background technology
Generally there is not Slope Transducer on the existing large excavator, have only gravity tester pin type to indicate the gradient, though it is simple and practical, but, display precision is too low, and there is not the output of relevant detection signal, the place slope detection signal that can not provide excavator for the electric control system and the detection surveillance of this excavator, so also will restrict the control system of excavator and the level of detection surveillance improves, at present, existing Slope Transducer mostly is unidirectional output, and the also difficult working environment that is applicable to large excavator of sensitivity and stability as Chinese utility model patent number is: 200820137880.7 disclosed bridge-type foil gauge Slope Transducer, the structural design of this Slope Transducer is very unreasonable, do not consider the influence of friction force, can't realize goal of the invention, be difficult to apply.The working environment that more can't adapt to large excavator.
Summary of the invention
The purpose of this utility model is intended to overcome the shortcoming and defect that prior art exists, and provides a kind of and can be applicable on the large excavator, reasonable in design, simple and practical
Strain-typeTwo-way Slope Transducer.
The technical solution of the utility model is such:
The two-way Slope Transducer of a kind of strain-type comprises strainometer 4 and by the bridge circuit that strainometer constitutes, it is characterized in that: also comprise heavy ball 1, flexible connecting member 2, flexible member 3, support spherical crown 5 and base 6; Described flexible member fixedly is loaded on base, and per two opposite spring element are one group, and heavy ball is connected by flexible connecting member with flexible member, longitudinally pastes strainometer respectively towards heavy ball one side and a side of back of the body heavy ball on flexible member; Described support spherical crown fixedly is loaded on the center at base, and heavy ball is positioned over supports the spherical crown top.
The utility model has simple and reasonable, easy to utilize advantage compared with prior art, and it can be widely used in various engineering machinery, and the working environment that adapts to large excavator is especially used.

Fig. 2 is a vertical view of the present utility model.
Fig. 3 is the full bridge diagram synoptic diagram of strainometer of the present utility model.
Embodiment
As depicted in figs. 1 and 2, the bridge circuit that structural representation of the present utility model, the two-way gradient sensor pack of a kind of strain-type draw together a heavy ball 1, four flexible connecting members 2, four flexible members 3, eight strainometers 4, be made of strainometer, support spherical crown 5 and base 6 etc.
Described four flexible member quadrature arrangement fixedly are loaded on base, and per two opposite spring element are one group, and in the present embodiment: four flexible members are divided into two groups.Flexible member couples together by flexible connecting member, adjust the length of flexible connecting member, make flexible member that the distortion of one initial bending be arranged, on each flexible member, longitudinally paste strainometer respectively, promptly be equivalent to a vertical equi intensity cantilever of placing towards a side of heavy ball one side and back of the body heavy ball.Described support spherical crown 5 fixedly is loaded on the center at base, and heavy ball is positioned over supports the spherical crown top.
Flexible connecting member is experienced the deflection of the heavy ball of two orthogonal directionss respectively, and suffered heavy ball generation power is delivered on the corresponding flexible member, flexible member is experienced two orthogonal directionss respectively by caused distortion of heavy ball deflection and power, and by the same bridge circuit that is subjected to the four stress gauges composition full-bridge of force direction, as shown in Figure 3.
The two-way Slope Transducer of a kind of strain-type of the present utility model, when slope change, because flexible connecting member is connected with heavy ball, the component that heavy ball is directly proportional with the gradient will change into the resistance variations of the distortion of flexible member-change into strainometer-and then the voltage that becomes electric bridge export.The flexible member of two groups of quadrature arrangement, the magnitude of voltage of two coordinate directions of output, its magnitude of voltage can convert after demarcating and can be value of slope.
