Abstract
The utility model relates to a centrifuge friction type highrise building fire escape device which comprises a cable wire, a steel wire winding with the cable wire, a rotational axis, a centrifugal wheel which is coaxial with the steel wire, a friction block, a spring and a cylinder-shaped casing. The steel wire winding with the cable wire, the centrifugal wheel and the centrifugal wheel rotates together. The friction block is respectively arranged at the upper and the lower wheel boarder of the centrifugal wheel and can slide along the radial direction of the centrifugal wheel to control the fall velocity of man body. The man body fall velocity of the utility model is subjected to the self-regulation of the centrifuge friction effect. The utility model is easy to be operated and is applicable for children and the old, the weak, the sick and the disabled and the automatic falling is realized after tying safety rope and jumping out of the window.
Description
The utility model relates to a kind of fire of high-rise building escape device, is specifically related to a kind of centrifugal friction principle of utilizing and controls the human body decrease speed, thereby realize that human body relies on the device of deadweight work in order to comparatively stable speed decline.
The fire of high-rise building escape device is a kind of device of personnel escape when being used for high building and catching fire.In still rare at present the application of China, and use comparatively general at western developed country to this device.From the patent documentation of finding, commonly used hanging type rope ladder, friction-type pulley arranged, climb forms such as formula rope, lift staircase.The use of most of devices is highly limited, needs two people to be used usually, need possess certain operative skill.This makes the escape the escape of fire clutch, especially children and the old,weak,sick and disabled personnel bring difficulty.
The purpose of this utility model just is to provide that a kind of structure is comparatively simple, volume is little, easy for installation, good reliability, easy to operate, can use building, not be only applicable to normal adults and be applicable to children and the escape of the old,weak,sick and disabled personnel's fire of high-rise building at various differing heights.
The purpose of this utility model is achieved in that
The utility model is a sub-assembly, comprises that an end has the steel wire rope of steel wire loop, the wire wheel of lay winding wire ropes, turning cylinder, with the coaxial centrifugal wheel of wire wheel, can be along centrifugal wheel warp-wise sliding friction piece, make parts such as spring that brake pad resets and shell.
Centrifugal wheel is connected in the outside of wire wheel, and the rotation of wire wheel will drive turning cylinder and centrifugal wheel rotates together; Turning cylinder is rotatably mounted on the cylindrical housing, and an end stretches out cylindrical housing and is connected with handle; Brake pad is separately positioned on the upper and lower of centrifugal wheel and takes turns along the place, every place is provided with two fan-shaped brake pads, and between two fan-shaped brake pads, settle the spring that brake pad is radially resetted by the sliding spring guide rod, when centrifugal wheel rotates, because action of centrifugal force will make four fan-shaped brake pads radially slide along centrifugal wheel;
When body weight pulling wire wheel rotates, centrifugal wheel rotates with speed, and centrifugal slider is radially outwards slided, and produces with the inwall of cylindrical outer casing contact and rub, to the rotation formation damping action of wire wheel.The speed that wire wheel rotates is big more, and this damping action is big more, thereby the speed that human body is descended is limited in certain numerical value, after wire wheel speed is reduced to a certain degree, spring makes centrifugal to move to the center of circle, reduces centrifugal friction with the casing cylinder inwall, and wire wheel speed is increased.
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is a main structure generalized section of the present utility model.
Fig. 2 is that A among Fig. 1 is to profile.
By Fig. 1 and Fig. 2 as seen, the utility model comprises: an end has the steel wire rope 11 of steel wire loop 4, the wire wheel 2 of the H type of lay winding wire ropes 11, turning cylinder 3, centrifugal wheel 1, fan-shaped brake pad 13, spring 8, spring guide 6, handle 5 and the cylindrical housing 12 coaxial with wire wheel 2.
Centrifugal wheel 1 is connected in the outside of the wire wheel 2 of lay winding wire ropes 11, and with turning cylinder 3 Joints, the rotation of wire wheel 2 will drive centrifugal wheel 1 and turning cylinder 3 rotates together;
Turning cylinder 3 is rotatably mounted on the cylindrical housing 12, and an end stretches out cylindrical housing 12, is connected with handle 5;
Four fan-shaped brake pads 13 are separately positioned on centrifugal wheel 1 and take turns along between two baffle plates 14 at place, every place is provided with two fan-shaped brake pads 13, and between two fan-shaped brake pads 13, settle the spring 8 that brake pad 13 is radially resetted by sliding spring guide rod 6, when centrifugal wheel 1 rotates, because action of centrifugal force will make four fan-shaped brake pads 13 radially slide along centrifugal wheel 1;
On cylindrical housing 12, be provided with one and adjust hole 7, can directly adjust from the outside easily, change the pretightning force of spring 8 back-moving spring 8 with sliding spring guide rod 6 corresponding sections;
For ease of using and settling, firm banking 9 can be set in the bottom of cylindrical housing 12.
For making steel wire 11 when unrolling, can guarantee one spring bearer plate element 10 to be set in cylindrical housing 12 with layered distribution.
The utility model can be applied to the fire disaster escaping of the building of differing heights by the steel wire rope that changes different length.
The utility model is to use like this:
The utility model is fixed on the body of wall, steel wire loop 4 lies in human body, when human body is degenerated from top to bottom, deadweight pulling wire wheel 2 rotates, centrifugal wheel 1 rotates with speed, centrifugal slider 13 is radially outwards slided, produce with the inwall of cylindrical outer casing 12 and contact and rub, to the rotation formation damping action of wire wheel 2.The speed that wire wheel 2 rotates is big more, this damping action is big more, thereby the speed that human body is descended is limited in certain numerical value, after wire wheel 2 speed are reduced to a certain degree, spring 8 makes centrifugal 13 to move to the center of circle, reduce centrifugal 13 friction with shell 12 cylinder inboard walls, wire wheel 2 speed are increased, guarantee that human body safety lands.After finishing using, available handle 5 is involved in steel wire rope 11, restores to the original state.
Because human body falling speed of the present utility model is subjected to the automatic adjusting of centrifugal friction effect, determined it can be easy to operation, be applicable to children and the old,weak,sick and disabled, only need fasten safe rope sling and jump out outside window and can realize automatic whereabouts.
