Abstract
The utility model relates to a high altitude steel cable performance descending device provided with adjustable speed, wherein, the device is used for performing when people on the high altitude steel cable downwards descends. A fixing frame is composed of a fixing plate and a connecting rod. The fixing plate is provided with a roller which is provided with a shaft. The roller is provided with a steel cable. The shaft at one end of the roller is provided with an inner gear wheel and a pinion wheel. The upper part of the pinion wheel is provided with intermediate wheels which are mutually meshed. The shaft in the roller is provided with a centrifugal friction flywheel and a one-way clutch. The utility model has the advantages that the structure is simple, the use is safe, the descending speed can be adjusted, the performance effect is favorable, and the generalization and the application prospect is bright.
Description
The utility model relates to a kind of high-altitude wirerope performance speed governing lowering means that uses when performing on the wirerope of high-altitude.
The performer jumps off and reduces to ground on the wirerope of high-altitude (20-200 rice), performance is especially as fairy maiden's program such as descend to the mortal world, require to descend at a slow speed, speed at 0.2/ second to 2 meter per seconds, give smug sensation, its performance is that the people ties up on the steel wire rope with lowering means, wire rope roll is on cylinder, brake drum revolution during decline, restriction drum speed and the people is descended at a slow speed, brake band or friction plate etc. are adopted in restriction, but unsuitable control rate in the decline process, and also dangerous sometimes, certain danger is arranged, its performance effect is undesirable.
The purpose of this utility model provides a kind of high-altitude wirerope performance speed governing lowering means, and can solve effectively can not speed governing and unsafe problem when the high-altitude wirerope descends.
The purpose of this utility model is achieved like this, constitute fixed mount by fixed head and connecting rod, the cylinder of dress band turning cylinder on two fixed heads, volume has steel wire rope on the cylinder, on cylinder one end internal gear is housed fixedly, pinion is housed on coaxial between internal gear and fixed head, axle of carrier pulley and idle wheel thereof are housed on the fixed head on the top that cogs, centrifugal friction flywheel and one-way clutch are housed in the cylinder.
The utility model is simple in structure, and is safe and reliable, can regulate the decrease speed speed, and good performance effect is arranged, popularizing application prospect light.
Below in conjunction with accompanying drawing structure of the present utility model is elaborated.
Fig. 1 is a sectional front view of the present utility model.
Fig. 2 is a centrifugal friction flywheel front view.
Fig. 3 is a centrifugal friction flywheel cross sectional side view.
Provide by Fig. 1, the utility model is to constitute fixed mount by fixed head 2 and connecting rod 9, the cylinder 6 of dress band turning cylinder on two fixed heads 2, steel wire rope 8 is housed on the cylinder, coaxial go up of cylinder 6 one ends fixedly is equipped with internal gear 5, on internal gear 5 and 2 of fixed heads coaxial pinion 4 arranged, and by axle 1 idle wheel 3 is housed on the fixed head 2 on pinion 4 tops, and be meshed with internal gear 5, pinion 4 respectively, centrifugal friction flywheel 7 and one-way clutch 10 are housed on the inside of cylinder 6 is coaxial.Internal gear 5 is 1: 8 with the gearratio of idle wheel 3; Centrifugal friction flywheel 7 its structures are that centrifugal wheel disc 13 peripheries upward are equipped with by rotating shaft 14 and get rid of piece 12, get rid of drag friction band 11 (seeing Fig. 2, shown in Figure 3) is housed on the piece 12.
Working condition of the present utility model is, the performer ties up on the steel wire rope 8, steel wire rope 8 twists in cylinder 6 peripheries, when performance descends, because human body gravity, driving cylinder 6 rotates, because of cylinder 6 and internal gear 5 are fixed, thereby driving internal gear 5 also rotates, internal gear 5 drives pinion 4 quick rotation by the idle wheel 3 that is meshed, pinion 4 is fixed with key with main shaft, main shaft rotates, and drives centrifugal friction flywheel 7 fast rotational by one-way clutch 10, and the centrifugal block for clutch use 12 of centrifugal friction flywheel 7 opens with cylinder 6 inwalls and produces moment of friction, the revolution of prevention cylinder, when the human body decrease speed increased, cylinder 6 rotating speeds increased, and drove centrifugal friction flywheel 7 rotating speeds and increased, the centrifugal force of centrifugal block for clutch use 12 increases, pressure via 11 pairs of cylinders of drag friction band increases, and causes that moment of friction increases, and braking moment increases, force cylinder 6 rotating speeds to reduce, human body descends and to slow down, otherwise, when human body descends when slow, centrifugal block for clutch use centrifugal force reduces, brake force reduces, and cylinder is accelerated rotation, the instantaneous self-control that realizes speed, so, the human body decrease speed can keep slowly even.The adjusting of decrease speed size can adopt the quality size of the centrifugal block for clutch use that pre-sets and sheet number and diameter of cylinder size to realize.For the ease of regulating the quality size of centrifugal friction flywheel, control the rotating speed size effectively, its friction free-wheel generally adopts multi-disc, as the 2-4 sheet, thereby guarantees that performer's being perfectly safe of performance that descend is reliable.
