Abstract
The utility model discloses an anti-falling self-controller which is a safety protecting device used for preventing operators working aloft from falling down. The anti-falling self-controller consists essentially of an outer cover, a central wheel, a central shaft, a pulling spring, a bilateral pallet claw, a guide sleeve, a pulling rope and a clockwork spring. Wherein, the central wheel consists of a wheel hub(9) and two ring-shaped stopping pallet wheels(10). The external circumference of each of the stopping pallet wheels(10) has a pallet wheel(11), and the middle part is provided with a central shaft sleeve(12) which is kept under the connecting status through the internal ring circumference through a rib strap and the stopping pallet wheels(10). The wheel hub(9) and the stopping pallet wheels(10) are under the status of static match. The internal part of the central shaft sleeve(12) is provided with a wearable ring(14). The utility model has the advantages of low cost and long application lifetime.
Description
Technical field
The utility model relates to a kind of safety device of work high above the ground personnel fall arrest.
Background technology
During operation, the most frequently used fall arrest apparatus is a safety belt to the workman aloft, because safety belt must link to each other with fixture, thereby has limited workman's scope of activities.Adopt the disclosed speed difference of CN2211832 autocontrol human body catching device, have bilateral ratchet on the ratchet, the mould of making is big, and the cost height is easy to wear between central shaft and the central axle sleeve simultaneously, has influenced the service life of catching device.
Summary of the invention
The utility model provides that a kind of cost is low, the anti-fall automatic controller of long service life.
The utility model adopts following technical scheme: a kind of anti-fall automatic controller, it mainly is made up of housing, centre wheel, central shaft, extension spring, bilateral ratchet, guide pin bushing, stay cord and clockwork spring, centre wheel is made up of wheel hub and two stop gears, stop gear is a ring-type, periphery is provided with ratchet, the centre is provided with central axle sleeve, and central axle sleeve is connection status by the interior ring week of rib and stop gear, and wheel hub and stop gear are the stationary fit state.
Be provided with wear-resisting lining ring in the central axle sleeve; The ring body of described stop gear is provided with boss, and the both sides of wheel hub cooperate with it and are provided with interior step; Described wear-resisting lining ring is copper sheathing, powder metallurgy cover or bearing.
Adopt as above technical scheme, stop gear is inlaid on the wheel hub, separately ratchet is made mould during manufacturing, then it is carried out selective hardening, thereby has saved production cost.Be provided with wear-resisting lining ring in the central axle sleeve simultaneously, reduced frictional force, strengthened wearability, prolonged the service life of catching device.

The specific embodiment
According to shown in Figure 1, the anti-fall automatic controller of the utility model, its main housing 1, centre wheel 2, central shaft, extension spring 3, bilateral ratchet 4, guide pin bushing 5, steel wire rope 7 and clockwork spring 8 are formed, bilateral ratchet 4 is stuck in the outside of the ratchet 11 of centre wheel 2, be provided with extension spring 3 between bilateral ratchet 4 and the housing 1, clockwork spring 8 is housed in the centre wheel 2.
According to Fig. 2 and shown in Figure 3, centre wheel 2 is made up of the stop gear 10 of wheel hub 9 and both sides.Stop gear 10 is a ring-type, is provided with ratchet 11 in outer shroud week.The center of stop gear 10 is provided with central axle sleeve 12, is provided with rib 13 between the interior ring week of central axle sleeve 12 and stop gear 10, and rib 13 blocks clockwork spring 8 in the time of in clockwork spring 8 is placed on wheel hub 9.The ring body of stop gear 10 is provided with boss 6, and wheel hub 9 both sides are equipped with and boss 6 corresponding in steps, thereby stop gear 10 can be inlaid in the wheel hub 9, by rivet both is fixed together again.Be provided with wear-resisting lining ring 14 in the central axle sleeve 12, wear-resisting lining ring 14 is copper sheathing, powder metallurgy cover or bearing.When human body moved less than retro-speed, the power of bilateral ratchet 4 ends of ratchet 11 bumps was less, under the effect of extension spring during use, the terminal ratchet 11 that passes through smoothly of bilateral ratchet 4, under the effect of clockwork spring 8, the steel wire rope 7 of pulling out is in hemicompact always and opens state, can freely work.In case slipping, human body falls, under the effect of acceleration of gravity, steel wire rope 7 is pulled out rapidly, stop gear 10 faster rotational speed, and the power of bilateral ratchet 4 ends of ratchet 11 bumps strengthens, and overcome the pulling force of extension spring 3, make bilateral ratchet 4 block ratchet 11, as long as load exists, stop gear 10 all can't rotate, steel wire rope 7 can not be pulled out, thereby human body is no longer dropped.
