Abstract
The invention discloses a life-saving descent control device. The life-saving descent control device comprises a cabin shell, a rope wheel hatch cover, a brake hatch cover, a bull gear, a pinion, a brake shaft, a rope wheel, blades, a friction plate, a spring and a centrifugal block steel backing. The principle of a friction speed reducer is characterized in that the friction plate is attached to the cabin shell through centrifugal force to generate friction force to limit the rotating speed of the bull gear. A gear speed reducer conducts speed reduction through the effects of friction force between the rope wheel and a rope and between the bull gear and the pinion, and a brake device can play a role in locking at the beginning of descent and can play a role in speed reduction and brake in the descent process. The life-saving descent control device is light and small, the effect of the life-saving descent control device is better through the two speed reducers, and the brake device is additionally arranged, so that safety coefficients are higher, and use is more reliable. The life-saving descent control device is used for high-altitude escape and rescue and has the advantages that the descent speed is uniform, safety of escape personnel is guaranteed, the escape personnel can escape without other auxiliary devices, and time and labor can be saved.
Description
Technical field
The present invention relates to high-altitude emergency escaping and rescue.
Background technology
At present, along with social development, work high above the ground is very general, when work high above the ground has an accident, or in the situation of the dangers such as high-rise breaking out of fire, traditional fast-escape mode is for passing through rope ladder, life chute, the facilities such as escape well are escaped, the length of supporting safety rope is 30 meters of left and right, but these facility costs are high, takes up room large, use inconvenience, especially the sick children of the old and the weak is inapplicable.In this case, descending lifeline is raw with regard to applying, but current various descending lifelines exist bulky mostly, complex structure, cost of manufacture is high, the perishable or slow shortcomings such as poor effect of falling, current survival equipment cannot meet work high above the ground personnel's emergency escape, and may occur that high altitude escape equipment cannot meet the high temperature that non-stop run produces, and affects the security performance of survival equipment, and may cause dangerous consequences.
Summary of the invention
The object of the invention is to address the deficiencies of the prior art, a kind of life saving descent control device that can self-contained heat sinking function is provided.
The technical solution used in the present invention is: a kind of lifesaving descent control device mechanism, comprise rope sheave hatchcover, cabin housing, brake hatchcover, gear wheel, rope sheave, pinion, blade, friction plate, centrifugal-block steel backing, spring and brake axle, it is characterized in that, described lifesaving descent control device has been installed vane heat dissipating, described rubbing device adopts spring type of attachment, from the middle stable decline progressively rubbing toward two ends.
Further, lifesaving descent control device mechanism friction plate adopts spring type of attachment.
Further, lifesaving descent control device mechanism its be provided with vane heat dissipating.
The invention has the beneficial effects as follows: when the lifesaving descent control device generation high temperature that works long hours continuously, the blade that can be installed by self rotates and produces Air Flow with pinion shaft, reaches heat sinking function.
Brief description of the drawings
Fig. 1 is the overall appearance figure of the embodiment of the present invention;
Fig. 2 is the cut-away view of the embodiment of the present invention;
Wherein: 1, rope sheave hatchcover; 2, cabin housing; 3, brake hatchcover; 4, gear wheel; 5, rope sheave; 6, pinion; 7, blade; 8, friction plate; 9, centrifugal-block steel backing; 10, spring; 11, brake axle.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of outward appearance of life saving descent control device, comprises rope sheave hatchcover 1 cabin housing 2 hatchcover 3 that brakes, and adopts screw to connect.
As shown in Figure 2, rope sheave 5 use straight pins and gear wheel 4 are fixing, then be installed in cabin housing 2, friction plate 8 is bonding with centrifugal-block steel backing 9, by spring 10, centrifugal-block steel backing 9 is connected with brake axle 11, brake axle 11 is fixed with pinion 6 use straight pins, and correspondence is installed in cabin housing 2, in order to ensure influencing each other between rope sheave mechanism and friction mechanism, adopt the form of cutting apart in housing 2 cabins, cabin.In the life saving descent control device course of work, due to friction plate 8, friction generates heat for a long time with cabin housing 2, in order better to make lifesaving descent control device heat radiation, keep optimum working performance, at brake axle 11, blade 7 is installed respectively up and down, make brake axle 11 produce Air Flow by blade 7 in the process of rotating, reach the effect of heat radiation, thereby ensure the service behaviour of lifesaving descent control device the best.
