The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1-3, a kind of elevator speed-measuring device, comprise car sheave 1, be located at the rope sheave cover 5 of car sheave 1 outside, be used for measuring the coder (not shown) of elevator speed, be opened in the mounting hole on the rope sheave cover 5, be installed on the rope sheave cover 5 and stretch into the first holes probe 4 and the second holes probe 4 in the rope sheave cover 5 by mounting hole, protrusion is arranged on a plurality of sensor blocks 3 on the bore edges 11 of car sheave 1 axle hole 12, with the elevator main control board that the first holes probe 4 and the second holes probe 4 are electrically connected, the first holes probe 4, the second holes probe 4 can be selected proximity transducer.In Fig. 2, a plurality of sensor blocks 3 are spaced along the circumferential direction of the axle hole 12 of car sheave 1, the first holes probe 4 and the second holes probe 4 all are oppositely arranged with sensor block 3, and all there is distance of reaction between the first holes probe 4 and the second holes probe 4 and the sensor block 3, guarantee that holes probe 4 can detect effectively, and the first holes probe 4 and the second holes probe 4 can not be aimed at two sensor blocks 3 simultaneously.Elevator is when moving by traction steel-cable, car sheave 1 is done as corresponding rotation by traction steel-cable, the rotative speed of car sheave 1 can reflect the running velocity of elevator, car sheave 1 when rotated, a plurality of sensor blocks 3 also rotatablely move thereupon, the first holes probe 4 then, the second holes probe 4 can be sensed the impulse singla that reflects sensor block 3 rotations, and (holes probe is whenever by the sensor block in distance range of induction, just produce an impulse singla), this impulse singla is sent in the elevator main control board, master control board calculates real-world operation speed and the service direction that just can obtain elevator, here the real-world operation direction of elevator is reflected by the phase sequence of impulse singla, namely in Fig. 2, it is up to suppose that car sheave is made clickwise reflection car, it is up also to set car in the master control board, if then actual car is really up, the phase sequence of the impulse singla of the first holes probe 4 then can be ahead of the phase sequence of the impulse singla of the second following holes probe 4, if the first holes probe 4 by the master control board acquisition, the phase sequence of the impulse singla of the second holes probe 4 is just in time opposite, reflect that then car sheave is reversing, car is descending, and elevator main control board can be exported the reverse signal.Adopt two holes probes 4 to come elevator is tested the speed, except can detect whether reverse, can also increase the accuracy that elevator speed detects.The elevator speed value that obtains by the first holes probe 4 and the second holes probe 4 at elevator main control board surpass the rated speed of lift value 15% the time, this elevator main control board output overspeed signal; When the absolute value of the deviation between the elevator speed value that elevator speed value that elevator main control board obtains by the first holes probe 4 and the second holes probe 4 and coder measure surpasses 10%, this elevator main control board output coder spurious signal.This elevator speed-measuring device, be used by the sensor block that arranges on the first holes probe, the second holes probe and the car sheave, realize obtaining real-world operation velocity amplitude and the service direction of elevator, thereby elevator overspeed and reverse are accurately monitored, the elevator real-world operation velocity amplitude that obtains by the first holes probe, the second holes probe can also compare with the observed reading of coder, whether feedback coder mistake, increases the elevator Operation safety.
In Fig. 2, sensor block 3 is that the head by bolt serves as.In Fig. 1, offer on axle hole 12 bore edges 11 of car sheave 1 along its circumferential spaced a plurality of tapped bore 2, equal screw thread fit has bolt in each tapped bore 2, and the head of each bolt all protrudes outside tapped bore, has formed sensor block 3.
In the present embodiment, as shown in Figure 3, car sheave 1 is corresponding to the position 6 at the bottom of the sedan-chair, be located on the rope sheave cover 5 of car sheave 1 outside and have two mounting holes at least, be provided with outside thread on the outside face of the first holes probe 4 and the second holes probe 4, the outside thread of each holes probe 4 all is through in the mounting hole, equal screw thread fit has a pair of nut on the outside thread of each holes probe 4, this a pair of nut clamps the bore edges of corresponding mounting hole, has realized the first holes probe 4 and the second holes probe 4 installing and fixing on rope sheave cover 5.Save like this probe bracket, also taken full advantage of rope sheave cover 5.
To sum up, this elevator speed-measuring device, simple in structure, cost is low, obtain to reflect the impulse singla of elevator speed and service direction by a plurality of sensor blocks on the first holes probe, the second holes probe induction car sheave, realization increases the safety of elevator operation to the monitoring of elevator overspeed and reverse and encoder fault, avoids occuring elevator accident.
