Background technology
At present, generally adopt two kinds of detecting devices commonly used to detect the exercise data of piler reel.
First kind of detecting device commonly used is coder to be directly installed in the rotating shaft of drive motor measure the reel exercise data, though this measurement mechanism can accurately be measured the reel exercise data, because the rotating speed of machine shaft is very high, coder damages easily.
Fig. 1 shows another kind of detecting device commonly used, and this detecting device transmits the reel exercise data by reel.As shown in Figure 1, in this detecting device, reel 1 is installed in the low speed end of retarder (not shown), the motor (not shown) is installed in the speed end of retarder, and friction wheel 2 contacts with the wheel limit 11 of reel 1, the rotation of the rotating band dynamic friction wheel 2 of reel 1, friction wheel 2 passes to coder 3 by axle 4 with movable information, the parallel axes of the axis of reel 1 and friction wheel 2.This detecting device is because the wheel limit 11 of reel 1 is too narrow little, and the area of contact between friction wheel 2 and the wheel limit 11 is little, thereby causes skidding easily, and wheel limit 11 also can give friction wheel 2 bigger application force, thereby can damage friction wheel 2.The exercise data that causes being delivered to coder 3 like this is inaccurate.

The specific embodiment
In order to further specify principle of the present utility model and structure, now in conjunction with the accompanying drawings preferred embodiment of the present utility model is elaborated, yet the described embodiment usefulness for furnishing an explanation and explaining only can not be used for limiting scope of patent protection of the present utility model.
Fig. 2 is the installing condition scheme drawing of reel exercise data detecting device of the present utility model on frame.
As shown in Figure 2, the utility model provides a kind of reel exercise data detecting device of piler.Two reels have been shown among Fig. 2, but structure of the present utility model for convenience of explanation and principle of work are that example describes with the reel 10 that is arranged in Fig. 2 left-hand side now.Reel exercise data detecting device of the present utility model is installed in end face 101 places of reel 10, is used to detect the exercise data of reel 10.
Described piler comprises: frame 80; Motor 50, it is installed on the frame 80; Retarder 70, its speed end is connected with motor 50; And reel 10, it is connected with the low speed end of retarder 70, is wound with rope 60 on the reel 10.
Reel exercise data detecting device of the present utility model comprises: friction cone 20, its periphery has the conical surface, have contact surface between the end face 101 of this conical surface and reel 10, rotate thereby make friction cone 20 to be driven by the phase mutual friction between the end face 101 of friction cone 20 and reel 10; And coder 30, itself and friction cone 20 are rotationally connected.
Compared with prior art, owing to the area of friction face between the end face 101 that has increased friction cone 20 and reel 10, transmit problem inaccurate, that equipment mechanism damages easily and service life is long so can overcome the exercise data of reel exercise data detecting device in the prior art.
Fig. 3 is the principle of work scheme drawing of reel exercise data detecting device of the present utility model.Fig. 4 is the installation sketch of reel exercise data detecting device of the present utility model.
As shown in Figure 3 and Figure 4, frictional area for friction face between the end face 101 that further increases friction cone 20 and reel 10, the contact surface of the axes intersect of the central axis of friction cone 20 and reel 10 between the end face 101 of the conical surface of friction cone 20 and reel 10 particularly intersects at the A point.Under this structure, can fully contact between the end face 101 of the conical surface of friction cone 20 and reel 10, thereby have the contact range of increasing between the end face 101 of the conical surface of friction cone 20 and reel 10.
The end face 101 that reel 10 has been shown among Fig. 3 passes to movable information the movement relation of friction cone 20, the rotational angle of supposing reel 10 is that the rotational angle of ω R and friction cone 20 is ω r, in similar triangle ABC and AB ' C ', R2/r2=R1/r1, according to movement relation ω r=ω R * R1/r1=ω r * R2/r2 is arranged, promptly do not have sliding phenomenon between the end face 101 of the conical surface of friction cone 20 and reel 10.
