the specific embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further elaborated.
A kind of mobile device of the scanning for the tower fault detection, as shown in Figure 1, described this device comprises reel 8, wiring unit 9, handle 6, worm type of reduction gearing 5, assembly pulley 7, cord grip 3 and base 1, key is, reel 8 is connected with handle 6 with worm type of reduction gearing 5, the steel rope of reel 8, by assembly pulley 7 location, on these assembly pulley 7 middle distance reels 8 pulley farthest, a cord grip 3 is arranged, and the turning cylinder of this pulley is connected with mechanical rotation counting machine 4; Reel 8 and assembly pulley 7 are arranged on base 1 jointly.
Described wiring unit 9 is the reverse-flighted screw structure, and the screw rod of this wiring unit 9 is coordinated with the axis of reel 8 by one group of gear cluster, realizes coiling and cloth line locking.
The power take-off shaft of described worm type of reduction gearing 5 is connected with reel 8 axis, and the power input shaft of worm type of reduction gearing 5 is connected with turning handle 6.
The fixed pulley that described assembly pulley 7 is distributed by three one-tenth " product " font forms.
Described cord grip 3 is comprised of spring and fabric wheel, and its inner spring is withstanding on steel rope tightly by the fabric wheel of lower end, and steel rope is fitted tightly on fixed pulley, and relative sliding can not occur.
There are two movably location hooks 2 at described base 1 two ends, but the free adjustment spacing.
Utilize the specific embodiment that this device is scanned the tower fault to be:
At first install two covers scanning mobile devices, concrete grammar is, the steel rope twined on reel is walked around to three fixed pulleys by the mode shown in Fig. 2, finally with cord grip, compresses.The bolt of rear end plate of location hook is unscrewed, adjusted the length of location hook, two location hooks are hung on two crossbeams up and down of tower top guardrail, tight a bolt.Again detector and ray follower are hung on the steel wire rope head of two cover scanning mobile devices, make detector lay respectively at the ray follower both sides that tower body is relative, adjust the position of detector and ray follower by handle folding and unfolding steel rope, make effective district be positioned at the initial point position of measurement, press the button that makes zero on the mechanical rotation counting machine, counting machine is made zero, so just completed dead work.
In testing process, determine the length of each unwrapping wire according to the detection distance of design, every rotation one circle of the turning cylinder of mechanical rotation counting machine, be counted as 1, the girth that is equivalent to assembly pulley middle distance reel that pulley farthest, can mean the displacement of steel rope accurately according to this pulley girth.
