Abstract

The utility model relates to a high-altitude safety elevating apparatus which is composed of a drum rolled with a steel cable in a casing, a second gear, a first gear, a shaft lever connected with the first gear, a rotational speed control apparatus arranged on the shaft lever and an escaping basket connected with the steel cable and arranged outside the casing. The rotational speed control apparatus comprises at least two bundle bushings arranged on the shaft lever and a fly wheel structure; the fly wheel structure is composed of a set casing, a rotating disk and at least three copper sheets arranged in the rotating disk. The utility model uses the centrifugal action as the copper sheets rotating to enhance the friction between the utility model and the set casing to control the shaft lever speed in order to achieving the aim of decelerating the lowering speed of the steel cable.

Description

High-altitude safety elevating apparatus

The utility model relates to a kind of high-altitude safe lowering or hoisting gear, relates in particular to a kind of skyscraper that is used for, and can effectively control the high-altitude safe lowering or hoisting gear of its rope decrease speed.

Since the usable land area narrow and small day by day with the exploding of population, the construction of super-high storied building is unavoidable, super-high storied building is for the people worries part no more than its safety devices, especially during breaking out of fire, how can escape quickly and safely, be the most important.Have at present and adopt tilting escape tube or helical form evacuation capsule, but escape tube is very easily frightened when using, and floor is higher, the human body decrease speed is faster, so security is very poor, for the elderly, children more can not be suitable for; And the helical form evacuation capsule produces centrifugal force because of spiral, easily causes human body to touch foreign object such as pipeline and injured, and this evacuation capsule is that dry goods is made, and also produces in escape is used in a great rush easily and tears.The cleaning of present in addition super-high storied building exterior wall is the high-altitude safe lifter of a kind of effectively control rate of utmost point needs also, and used cable car is unsatisfactory because of the structure of its speed control, when excessive velocities and dangerous, in case and power interruptions, be suspended from also very dangerous in midair.

The purpose of this utility model is to provide a kind of high-altitude safe lowering or hoisting gear that can control the rope decrease speed with machine driving effectively.

The purpose of this utility model is achieved in that a kind of high-altitude safe lowering or hoisting gear is by housing, with be located at the housing curls inward reel of steel cable arranged, second gear that is connected with reel one side, first gear that is meshed with second gear, being located at the axostylus axostyle of first gear, one side and the revolution speed control device of being located on the axostylus axostyle forms, the steel cable upper end is fixedly arranged in the ring, the other end stretches out the outer escape basket that connects of housing, it is characterized in that described speed-controlling device is that at least 2 beam rings that are arranged on the axostylus axostyle overlap and a flywheel structure, flywheel structure is by a set casing, one rotating disc and at least 3 copper sheets are formed, when rotating speed is fast, copper sheet reaches the deceleration purpose because of centrifugal action and the mutual friction of the inwall of set casing in the rotating disc, above-mentioned beam ring cover is then by the beam ring cover, screw rod and the cylinder that is provided with are between the two formed, mat adjustment screw rod comes the frictional force between index drum and the beam ring cover, and realizes adjusting the rotating speed of axostylus axostyle.

The utility model has the advantages that safe and reliablely, all use machine driving, do not need additionaling power, and escape personnel or cleanup crew place oneself in the midst of in the basket, do not touch or the foreign object that rubs damages, when floor is too high, also can take the mode of plugging into, so also very economical.

Below with drawings and Examples so that structure of the present utility model is described in detail.

Description of drawings:

Fig. 1 is stereoscopic figure of the present utility model.

Fig. 5 is the illustrative view of flywheel structure.

By shown in Fig. 1～5 as seen, this high-altitude safe lowering or hoisting gear is by housing 1, with the reel of being located in the housing 2, one second gear 3, one first gear 4, the axostylus axostyle 41 that is connected with gear 4, being placed at least 2 beam rings cover 5 on this axostylus axostyle 41 and flywheel structure 8 and escape basket 7 forms, the periphery of reel 2 is provided with a groove 21, its curls inward has steel cable 22, the upper end of steel cable 22 is fixedly arranged in the retainer ring 11, its end stretches out outside the housing 1 and is connected with escape basket 7, the middle position of reel 2 one sides is provided with a spool shaft 23, its mat bearing 24 is supported in enclosure interior, the opposite side mat screw 25 and second gear 3 of reel 2 fix, it is inner and be meshed with first gear 4 to it is characterized in that second gear, 3 mat bearings 31 are supported in housing 1, the center of first gear, 4 one sides convexes with an axostylus axostyle 41, axostylus axostyle 41 two

ends mat bearings

42,43 are supported in housing 1 inside, axostylus axostyle 41 is provided with at least 2 beam ring covering devices of adjustable axle bar speed and the flywheel mechanism 8 that prevents to exceed the speed limit, the beam ring covering device is by beam ring cover 5,

screw rod

51,52 cylinders 53, support bar 54, spring 55 is formed, beam ring overlaps 5 surfaces and has tongue and groove, the beam ring cover 5 that wherein is positioned at the end, right side has a control screw rod 51, remaining beam ring overlaps the 5 next adjustment screw rods 52 that respectively are provided with, at beam ring cover 5 and screw rod 51, between 52, respectively be provided with a cylinder 53, run through a support bar 54 in cylinder 53 center of circle parts, and below support bar 54, be provided with spring 55; Flywheel structure 8 is made up of a set casing 81, a rotating

disc

82 and 3 copper sheets 83 at least, set casing 81 is fixedly arranged on the pedestal 12,82 of rotating discs are fixedly arranged on the axostylus axostyle 41, the inner area of rotating disc 82 is divided at least 3 spaces, respectively establish in each space and put a copper sheet 83, between copper sheet 83 and the set casing 81 default spatial degrees is arranged.

In said structure, seat is down in the escape basket as survivor or staff, the mat body weight falls steel cable, reel 22 rotations, and drive second,

first gear

3,4 and axostylus axostyle 41 rotations, and rotary speed changes the cylinder 53 and the friction of beam ring inner room with

screw rod
