Background technology
At present, the structure of water power hydraulic engineering winch hoist, the detection that has determined its stroke is generally the rotating cycle by detection headstock gear reel, then goes out the stroke value of headstock gear by the multiplying power Conversion Calculation of pulley system.Reel for the wire rope multi-lay winding, because the coiling diameter of the wire rope of different layers is different, thus checkout gear also to revise different winding layers, and this correction value often precision is low, drift is larger, need the professional often to adjust, and the workload of the work of adjustment is large and loaded down with trivial details.
Summary of the invention
The technical problems to be solved in the utility model is: the problem for above-mentioned existence provides a kind of winch hoist simple in structure, the stroke that can precise and stable detection computations goes out headstock gear, with solve in prior art precision low, revise the large problem of workload of adjusting.
The technical scheme that the utility model adopts is: winch hoist, it is characterized in that: it comprise the outermost pulley of the fixed pulley group that is wound with wire rope, coaxial be fixed in gear on this pulley, with this gear meshed gears reduction gearing mechanism, and be fixedly installed in connecting axle on this gear reduction transmission mechanism, the coaxial connection absolute value optoelectronic encoding of connecting axle other end device wherein, this photoelectric encoder is connected with the automatically controlled device of headstock gear by holding wire.
The worm and gear reduction gearing mechanism is set between described connecting axle and photoelectric encoder, wherein connecting axle is connected with photoelectric encoder by the worm screw in the worm and gear reduction gearing mechanism, worm gear in the worm and gear reduction gearing mechanism is provided with cam mechanism, and near this worm gear, the microswitch corresponding with cam mechanism is set.
Described microswitch adopts the V-type microswitch of Omron Corp, and power supply is selected DC8V/21A or 30V/14A.
Described photoelectric encoder adopts the GEMPLE GAX of company series multi-turn absolute value optoelectronic encoding device, and output signal is SI synchronous serial signal or RS485 bus signals.
The beneficial effects of the utility model are: principle of the present utility model is not to calculate the stroke value of headstock gear by the rotating cycle that detects the headstock gear reel, but calculates the stroke value of headstock gear by conversion by the rotating cycle that detects the outermost pulley of headstock gear fixed pulley group.Structurally, the pulley that is wound with steel wire rope of windlass is connected to the absolute value optoelectronic encoding device through gear, gear reduction transmission device and connecting axle successively, utilize the steel wire rope of windlass rotary speed to become the relation of a constant ratio with headstock gear keying speed, can calculate accurately the stroke of headstock gear, need not the professional after once setting up simultaneously adjusts again, not only guaranteed the stability of testing result, and reduced and measured large and loaded down with trivial details adjustment work, have obvious technology, economy and social benefit.
Description of drawings
Fig. 1 is structure chart of the present utility model.
The specific embodiment
As shown in Figure 1, the present embodiment comprise the pulley 1 that is wound with wire rope 4, coaxial be fixed in gear 2 on this pulley, with this gear meshed gears reduction gearing mechanism 3, and be fixedly installed in connecting axle 5 on this gear reduction transmission mechanism; The worm screw of the connecting axle 5 coaxial connection worm and gear of other end reduction gearing mechanisms 6 wherein, the coaxial connection absolute value optoelectronic encoding of this worm screw other end device 9, this photoelectric encoder is connected with the automatically controlled device 10 of headstock gear by holding wire; The worm gear of worm and gear reduction gearing mechanism 6 is provided with cam mechanism 7, and near this worm gear, the microswitch 8 corresponding with cam mechanism 7 is set.
Described microswitch 8 adopts the V-type microswitch of Omron Corp, and power supply is selected DC8V/21A or 30V/14A.
Described photoelectric encoder 9 adopts the GEMPLE GAX(GAM of company) serial multi-turn absolute value optoelectronic encoding device, output signal is SI synchronous serial signal or RS485 bus signals.
The operating principle of the present embodiment is: winch hoist is in lifting process, and steel wire rope of windlass 4 can drive fixed pulley outside pulley 1 rotation, and its rotary speed becomes a constant ratio relation with the keying speed of headstock gear; Utilize the pulley side gear 2 that rotarily drives of pulley 1 to rotate, and driven wheel reduction gearing mechanism 3 carries out primary speed-down, gear reduction transmission mechanism 3 rotates by the worm screw that connecting axle 5 drives in worm and gear reduction gearing mechanism 6, this worm screw drives 9 rotations of absolute value optoelectronic encoding device, absolute value optoelectronic encoding device 9 output SI synchronous serial signals or RS485 bus signals demonstrate the height value of rolling open and close machine to rolling open and close machine electric control gear 10 after this electric control gear converts.Because the rotary speed of steel wire rope of windlass 4 becomes a constant ratio relation with the keying speed of headstock gear, simultaneously, the rotating speed of wire rope 4 also becomes a constant ratio relation with the rotating speed of absolute value optoelectronic encoding device 9, therefore the signal of absolute value optoelectronic encoding device 9 outputs also becomes the constant ratio relation with the keying speed of headstock gear, accuracy of detection is high and stable.
Also be provided with cam mechanism 7 on the worm gear of the present invention in worm and gear reduction gearing mechanism 6.After gear reduction transmission mechanism 3 carries out secondary speed-reducing by connecting axle 5 driving worm and gear reduction gearing mechanisms 6; cam mechanism 7 is rotated at a slow speed; correct position in cam mechanism 7 rotations arranges microswitch 8; when microswitch 8 is touched by cam mechanism 7 rotations; can send the switching value signal to rolling open and close machine electric control gear 10, the redundancy that this signal the can be used as rolling open and close machine position undetermined protection of transfiniting.
Utilize above-described embodiment to carry out the principle of headstock gear stroke detection as follows: the number of turns that at first obtains connecting axle 5 rotations by absolute value optoelectronic encoding device 9, again according to the gearratio of gear 2 and gear reduction transmission mechanism 3, calculate the rotating cycle of pulley 1, open and close at last the ratio of speed and pulley 1 velocity of rotation according to headstock gear, can calculate the stroke value of headstock gear; This detection method testing result is not subjected to the impact of wire rope multi-lay winding, and precision is high and stable.
