Embodiment
Below in conjunction with specification drawings and specific embodiments, the present invention is further elaborated.
A kind of scanning mobile device for tower fault detect, as shown in Figure 1, this device described comprises reel 8, wiring unit 9, handle 6, turbine and worm speed reduction unit 5, pulley blocks 7, cord grip 3 and base 1, key is, reel 8 is connected with handle 6 with turbine and worm speed reduction unit 5, the wire rope of reel 8 is located by pulley blocks 7, this pulley blocks 7 middle distance reel 8 pulley farthest has a cord grip 3, and the rotation axis of this pulley is connected with mechanical rotation counter 4; Reel 8 and pulley blocks 7 are arranged on base 1 jointly.
Described wiring unit 9 is 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 set, realizes coiling and cloth line locking.
The power output shaft of described turbine and worm speed reduction unit 5 is connected with reel 8 axis, and the power input shaft of turbine and worm speed reduction unit 5 is connected with turning handle 6.
Described pulley blocks 7 is made up of the fixed pulley that three become triangle disposition to distribute.
Described cord grip 3 is made up of spring and fabric wheel, and the spring of its inside by the fabric wheel of lower end top tightly on a steel cord, makes wire rope fit tightly on fixed pulley, relative sliding can not occur.
There are two moveable location hooks 2 at described base 1 two ends, can free adjustment spacing.
This device is utilized to the embodiment that tower fault scans to be:
First install two cover scanning mobile devices, concrete grammar is, the wire rope twined on reel is walked around three fixed pulleys by the mode shown in Fig. 2, finally compresses with cord grip.Unscrewed by the set bolt of location hook, two location hooks are hung on two crossbeams up and down of tower top guardrail, tight a bolt by the length of adjustment location hook.Again detector and ray follower are hung on the steel wire rope head of two cover scanning mobile devices, detector and ray follower is made to lay respectively at the relative both sides of tower body, the position of detector and ray follower is adjusted by handle folding and unfolding wire rope, effective district is made to be positioned at the initial point position of measurement, press the zero button on mechanical rotation counter, make counter clear, this completes preliminary work.
In testing process, determine the length of each unwrapping wire according to the detecting distance of design, the rotation axis of mechanical rotation counter often rotates a circle, is counted as 1, be equivalent to the girth of pulley blocks middle distance reel that pulley farthest, the displacement of wire rope can be represented according to this pulley circumference accurately.
By the length of each unwrapping wire of revolution counter, arrive the auto-lock function due to turbine and worm after unwrapping wire length, can release handle, go service data to obtain system log data.Unwrapping wire is next time carried out again after data acquisition.
After total data obtains, by the personnel under tower, detector and ray output unit are unloaded, due to the effect of cord grip, wire rope can not be loose, now turbine and worm speed reduction unit is unloaded, be connected directly between by turning handle on reel and carry out take-up, when not having speed reduction unit, take-up speed can complete very soon.
This tower scanning manual hoisting device all adopts aluminium alloy and plastic material except wire rope, bearing and indivedual coupling shaft, and package unit is very light, and be easy to carry tower top.
