Abstract
A high-altitude slow-falling machine is composed of hook, rope, pulley, planetary gear and sun gear, and features that a speed limiter consisting of friction block, friction disk and sun gear is driven by speed increaser, and the friction force of speed limiter is used to limit the falling speed of object.
Description
The utility model belongs to life.
Aloft work is a kind of relatively dangerous occupation, because once have an accident, operator's safety is difficult to ensure, usually operator's escape is by rope ladder or evacuation capsule, escape such as facility such as escape well etc., but above-mentioned lifesaving appliance cost height not only, and it is big to take up room, just use inconvenience, inapplicable to old person especially.
It is a kind of safe and reliable easy to use that the purpose of this utility model is to provide, the low aloft work life of holding concurrently of cost.
The technical essential that the utility model adopted is to drive a centrifugal governor by a speed increaser, by the rotative speed of velocity limiter restriction pulley, reaches slow purpose of falling.
Fig. 1 is a high-altitude slow-descending machine scheme drawing
Fig. 2 is a high-altitude slow-descending A-A sectional view
Below by accompanying drawing an embodiment of the present utility model is further described.(1) is hook among the figure, just the time spent is linked up with an end and is fixed on the fixture, the fixing slow skeleton (2) that falls machine of one end, a wheel shaft (3) is fixed by frame center, fix a planet circular system speed increaser (6) by planet wheel spindle (5) on cover one pulley (4) pulley on the wheel shaft, planet circular system and the gear mesh that is enclosed within the sun wheel (7) on the wheel shaft (3) have axial notch (8) on the sun wheel, in friction shoe (9) is housed, form velocity limiter.When gliding, object drives pulley (4) by rope (10), planet circular system speed increaser (6) speedup fixing on the pulley is exported to centrifugal governor with the rotative speed amplification of pulley, produce friction force because centnifugal force is fitted friction shoe (9) and speed limit friction disc (11) this moment, the rotating speed of restriction pulley, thus realize the slow purpose of falling of constant speed.(12) be outer cover, (13) are external toothings, and external toothing and friction disc (11) are fixed on the skeleton (2) by screw (14).(15) (16) are track adjusting wheels, and (17) are the wheel ropes.
The personnel escape when having an accident that the utility model is not only applicable to high-rise building also can be equipped on aspect the aloft work such as fire-fighting, geology, electric power.It is life saving apparatus a kind of simple in structure, safe and reliable.
Claims (3)
1, a kind of high-altitude slow-descending machine, by hook, formations such as rope, it is characterized in that by being enclosed within wheel shaft [4], and be fixed on planet wheel spindle [5] on the pulley [4], planetary wheel [6], sun wheel [7], the speed increaser that external toothing [13] constitutes drives one by being enclosed within the velocity limiter that sun wheel [7] on the wheel shaft [3] and the friction shoe [9] in the sun wheel upper groove [8] and friction disc [11] constitute.
2, by the described high-altitude slow-descending machine of claim 1, it is characterized in that described external toothing (13) is fixed on the skeleton (2) by bolt (14).
3, by the described high-altitude slow-descending machine of claim 1, it is characterized in that described speed limit friction disc (1) is fixed on the skeleton (2) by bolt (14).
