Abstract
The utility model relates to a special shaft sleeve weighing sensor for an elevator. The shaft sleeve weighing sensor not only has high weighing precision and good stability, but also is small in size and low in cost. The shaft sleeve weighing sensor comprises a weighing sensor. An inner ring of the weighing sensor is embedded in an outer ring of the weighing sensor, two opposite sides of the inner ring are provided with a cross beam, two strain gauges are respectively disposed on the cross beam, a cable outlet hole is disposed on the outer ring, and outgoing cables of the two strain gauges are led out through the cable outlet hole. The shaft sleeve weighing sensor has the advantages that the shaft sleeve weighing sensor is the special weighing sensor for a construction building elevator, and can not only be used to measure weight of loaded objects or people, but also be matched with a weighing instrument to constitute a construction lifting load limiter; and the shaft sleeve weighing sensor can be applied to all occasions of using a axle pin sensor, and moreover, the shaft sleeve weighing sensor has higher safety performance than the axle pin sensor.
Description
Technical field
The utility model relates to a kind of both had weighing precision and good stability, and it is little to have volume again, and the special-purpose axle sleeve LOAD CELLS of the lifter of low cost of manufacture belongs to LOAD CELLS and makes the field.
Background technology
200520078866.0 quiet, moving dual-purpose shovel loader scale; Comprise axial pin type sensor and signal processing apparatus; On shovel loader lifting arm outer support frame, magnetic induction is housed near switch; An axial pin type sensor respectively is installed in the axis hole of shovel loader lifting cylinder, and signal processing apparatus is connected with axial pin type sensor near switch with magnetic induction, in shovel loader lifting arm axis hole, is separately installed with horizontal displacement sensors and is connected with the amplifier of signal processing apparatus with the perpendicular displacement sensor.Shortcoming: when the strainometer of weighing all is arranged on the pivot pin with being fixedly connected; And on the pivot pin in order to weigh; On pivot pin perforating device a plurality of strainometers, whole pivot pin is in the state that a kind of each several part ability to bear does not wait for a long time, after pivot pin works long hours; Metal fatigue can cause the pivot pin strain, has great potential safety hazard.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of both had weighing precision and good stability, it is little to have volume again, the special-purpose axle sleeve LOAD CELLS of the lifter of low cost of manufacture.
Design proposal: in order to realize above-mentioned purpose of design.The utility model is on structural design, and the application's outer ring and otic placode are fixed, and pivot pin is through at the endoporus of sensor, and endoporus links to each other with the sensor outer ring through the crossbeam of both sides.After pivot pin received load, pivot pin passed to endoporus with power, and the crossbeam that links to each other with endoporus is also stressed thereupon.The strainometer that is affixed on the crossbeam can be exported the faint physical deformation of crossbeam with the mode of electric signal, the size of its output electric signal is directly proportional with the size of the suffered load of crossbeam.
Technical scheme: the axle sleeve LOAD CELLS, it comprises LOAD CELLS, the inner ring of said LOAD CELLS is embedded in the outer ring; The relative both sides of inner ring are provided with crossbeam; Two strainometers are housed respectively on the crossbeam, and the outer ring has wire hole, and the outlet of two strainometers is derived from wire hole.
The utility model is compared with background technology, and the one, this LOAD CELLS is the special-purpose LOAD CELLS of building hoist for building, both can be used for detecting contained object in the cage or personnel's weight, also can cooperate with weighing instrument, forms construction up-down load limiter; The 2nd, adopt the occasion of pivot pin sensor applicable to all, and have higher security performance than pivot pin sensor.

Fig. 2 is the stereographic map of axle sleeve LOAD CELLS.
Fig. 3 is the principle of work synoptic diagram of axle sleeve LOAD CELLS.
Embodiment
Embodiment 1: with reference to accompanying drawing 1-3.A kind of axle sleeve LOAD CELLS, it comprises LOAD CELLS, the inner ring 2 of said LOAD CELLS is embedded in the outer ring 1; The relative both sides of inner ring 2 are provided with crossbeam 3; Two strainometers 4 are housed respectively on the crossbeam, and outer ring 1 has the outlet of wire hole 5, two strainometers 4 and from wire hole 5, derives.Said crossbeam 3 both sides are the groove-like structure.The endoporus of described inner ring 2 and pivot pin 6 diameters, otic placode 7 apertures are complementary.Have a plurality of mounting holes on described outer ring 1 and the inner ring 2.
After the outer ring of axle sleeve LOAD CELLS and otic placode were fixed on the otic placode through screw, pivot pin passed the inner ring aperture of axle sleeve sensor, and the inner ring aperture links to each other with axle sleeve sensor outer ring through the crossbeam of both sides; After pivot pin received load, pivot pin passed to the inner ring aperture with power, and the crossbeam that is one with the inner ring aperture is also simultaneously stressed; The strainometer that is affixed on the crossbeam can be exported the faint physical deformation of crossbeam with the mode of electric signal, the size of output electric signal is directly proportional with the size of the suffered load of crossbeam, gets final product the size of control load; Because the axle sleeve LOAD CELLS is fixed on the otic placode through the outer ring, force way with fixed by force direction, pivot pin is no longer born the function of weighing; Only bear this simple function of load, make that the stressed pressure of whole pivot pin is even, effectively promoted the working strength of pivot pin; Even the crossbeam of inner ring because the working time is of a specified duration excessively, aging, fracture, can not make the function of axle sleeve LOAD CELLS maximum weight at once malfunctioning yet, be convenient to the staff and make regular check on and safeguard; When aging need the replacing occurring, only need the axle sleeve sensor be removed, what more renew gets final product; Need not whole pivot pin extracted; Greatly reduce maintenance difficulties, save time, raise the efficiency, be not only applicable to the weighing and sensing work of lifter; The physical construction of every similar condition of work requires to weigh load, and this axle sleeve LOAD CELLS all can satisfy its requirement.
What need understand is: though the foregoing description is to the mentality of designing of the utility model simple text description of contrasting; But these text descriptions; Just the simple text of the utility model mentality of designing is described; Rather than to the restriction of the utility model mentality of designing, any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the utility model.
