Fig. 3 is a manual modulator structural representation of the present utility model.
The specific embodiment
With reference to the accompanying drawings the utility model is elaborated
Parts of the present utility model are formed:
Connect cable wire 1, connect safety button 2, suspension body 3, descending lifeline assembly 4, go up manual modulator 5, downslide dragline 6, traction dragline 7, following manual modulator 8, spacing ring 9, buckle 10, clamping screw 11, earth anchor 12, suspension ring 13, fixing body 14, descending lifeline driving wheel 15, driving wheel 16, driven pulley 17, eccentric wheel 18, deceleration piece 19, balancing spring 20, deceleration box 21, lid 22, handwheel 23, leading screw 24, bottom plate 25, fixed block 26, locking sliding shoe 27, pump nozzle 28, slide-and-guide body 29, upper mounted plate 30, connection cord 31, warning sign 32, last connecting ring 33, following connecting ring 34, safety rope 35, safety door hook 36.
On the fixing body 14 of descending lifeline driving wheel 16 is housed, driving wheel 16 links to each other with descending lifeline driving wheel 15, and fixing body 14 links to each other with deceleration box 21.The driven pulley 17 that is meshed with driving wheel 16 is housed in deceleration box 21, eccentric wheel 18 is housed on driven pulley 17, eccentric wheel 18 is equipped with deceleration piece 19, and balancing spring 20 is housed on the deceleration piece 19.
Drive driving wheel 16 and rotate when descending lifeline driving wheel 15 rotates, the driven pulley 17 that is meshed with driving wheel 16 rotates, and driven pulley 17 drives deceleration piece 19 and rotates, because off-centre makes deceleration piece 19 and deceleration box 21 frictions, reaches the purpose of deceleration.
To connect cable wire 1 is fixed on the derrick after safety button 2 links to each other with being connected, connecting safety button 2 links to each other with suspension body 3 and links to each other with an end of downslide dragline 6, the other end of downslide dragline 6 passes behind the connecting ring of clamping screw 11 with buckle 10 lockings, the other end of clamping screw 11 links to each other with earth anchor 12, place earth anchor 12 underground, the back that links to each other is stretching with downslide dragline 6 with clamping screw 11, and is after downslide dragline 6 is stretching, in the appropriate location of the lower end of downslide dragline 6 that spacing ring 9 is fixing.
Descending lifeline assembly 4 is housed in suspension body 3, on descending lifeline driving wheel 15, be wound with traction dragline 7, the two ends of traction dragline 7 link to each other respectively at last manual modulator 5, down manual modulator 8, last manual modulator 5 after linking to each other, following manual modulator 8 are hung on respectively on the downslide dragline 6, wherein will go up manual modulator 5 and place the upper end of downslide dragline 6, manual modulator 8 places the lower end of downslide dragline 6 down.And the warning sign 32 that will descend manual modulator 8 is fixed on the following manual modulator 8.Manually modulator is being equipped with connecting ring 33 on the bottom plate 25, and last connecting ring 33 links to each other with following connecting ring 34, and following connecting ring 34 is equipped with safety rope 35, and safety door hook 36 is equipped with at the two ends of safety rope 35 respectively, has promptly finished the whole erection process of escape device to this.
When the operator is positioned at job site generation burst, (when having hindered passage) can link to each other safety door hook 36 with the safety belt that the workman wears, and hand-held manual modulator 5 glides along downslide dragline 6, in the downslide process, the traction dragline 7 that links to each other with last manual modulator 5 drives down, and descending lifeline driving wheel 15 rotates, descending lifeline driving wheel 15 drives driving wheel 16 and rotates, driving wheel 16 drives driven pulley 17 and rotates, driven pulley 17 is equipped with eccentric wheel 18, eccentric wheel 18 is equipped with deceleration piece 19, because eccentric position reaches new balance with balancing spring 20 under action of centrifugal force, slowing down this moment produces friction between piece 19 and the deceleration box 21.When people's quality is big, sliding force is also big, the power of pulling descending lifeline driving wheel 15 is also big, the faster rotational speed of descending lifeline driving wheel 15, frictional force increases, because the frictional force increase descends descending lifeline driving wheel 15 rotating speeds, reaches at the uniform velocity decline, thereby guarantee that the workman does not have big impact when arriving ground, make the workman safer.
In whole downslide process, manually modulator can be under escape personnel's control, to drive screw mandrel by rotation hand wheel moves locking sliding shoe 27, in order to regulate the gap between locking sliding shoe 27, downslide dragline and the slide-and-guide body 29, in order to increase or the power of reducing friction, thereby reduce or increase sliding force, to guarantee gliding the at the uniform velocity impulsive force of minimizing escape personnel when arriving ground.
When said process carried out, following manual modulator 8 was pulled on the upper end of downslide dragline 6 under the drive of traction dragline 7, repeats said process the other staff of job site are fled the scene greatly, arrived safety place.
