Embodiment recited above is described the preferred embodiment of the present invention; not the spirit and scope of the present invention are limited; under the prerequisite that does not break away from design concept of the present invention; various modification and improvement that in this area, common engineers and technicians make technical scheme of the present invention; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection, all be documented in claims.
The present invention is provided with one in lower house can be in the drive pulley of lower house center rotating, by with the coaxial gear up of drive pulley after pass motion to friction component, brake pad in friction component radially throws away under centrifugal action, compress the sidewall of upper shell, thereby produce friction the restriction decrease speed.Safety rope is through spaced winding in the fixing braking double-screw bolt of two centre-to-centre spacing on drive pulley, and the braking double-screw bolt is contained on brake holder, and brake holder one end can install around braking rotating shaft rotation on lower house, the other end and be connected through the braking stay cord of back-moving spring.When the people strains braking during stay cord, the moving rotating shaft of brake holder coiling is rotated, and safety rope is pressed between the projection on braking double-screw bolt and lower house, thereby makes safety rope stop sliding, and realizes hovering of arbitrary height in the decline process.
Mode of braking of the present invention is mechanical type braking, by pulling braking stay cord brake activation mechanism, realizes hovering at an arbitrary position.
In the present invention, gear adopt the mode of interference fit to be contained on the axle be made of one with drive pulley and be arranged on upper shell and lower house in the middle of hole in, gear shaft and friction component are fitted together and are arranged on upper shell and lower house in corresponding hole, the braking rotating shaft is fixed on lower house, but brake assemblies is arranged in the braking rotating shaft, also the moving rotating shaft of coiling is rotated.The braking stay cord is bored a hole and is passed back-moving spring through the stay cord on the lower house sidewall and is connected on brake assemblies with nut.Brake pad is contained on the supporting studs be fixed between upper end cover plate and lower end cover plate, also can rotates around supporting studs, and when friction component rotates, brake pad can throw away under centrifugal action.
After safety rope is bored a hole through the safety rope first on the lower house sidewall, again through spaced winding in the fixing braking double-screw bolt of two centre-to-centre spacing on drive pulley, and then wear back in the middle of the fixing braking double-screw bolt of two centre-to-centre spacing, last safety rope second from the lower house sidewall passes.
When safety rope descends under the body weight effect, the drive drive pulley is rotated, by rotating with the coaxial gear driven gear shaft of drive pulley, thereby the friction component that makes to be contained on gear shaft rotates, brake pad in friction component radially throws away under centrifugal action, compress the madial wall of upper shell, thereby produce the decrease speed of frictional force restriction safety rope.The safety rope decrease speed is faster, after gear drive, the rotary speed of friction component is faster, and centrifugal force is also larger, and the pressure between brake pad and upper shell madial wall is larger, thereby the resistance that the restriction safety rope descends is just larger, can make in this way safety rope descend with substantially invariable speed.During normal decline, brake assemblies lifts under the effect of back-moving spring, safety rope can freely pass through brake assemblies, when running into obstacle need to brake in the decline process, pull the braking stay cord, depress back-moving spring, safety rope is pressed on the projection on the lower house sidewall by two braking double-screw bolts, thereby realizes hovering.
The present invention is a kind of high building escape deceleration device, can hover at arbitrary height, simple in structure, cost is low, reliability is high, can be widely used in the emergency escape that high building, steamer etc. are located, and also can be used for that personal security on helicopter descends and the aspect such as rescue and relief work.
Due to the present invention in use, after safety rope one end descends, the other end is raised to top, an end that can be used in top second people that descends, the descending lifeline of this kind of structure can be described as reciprocating descent control device.
