Description

Safety self-saving landing device for grand building on fire

The utility model relates to building lifesaving appliance technical field.

At present, along with increasing of population, expanding economy, high-rise day different increasing, people require also to get more and more to the various safety measures of shelter, because the high building fire fighting device is complete inadequately, it is more outstanding to leave over disaster hidden-trouble, once catch fire, people's escape is difficulty, and hope can be withdrawn the scene as early as possible in face of disaster, if the breaking out of fire accident, people can't withdraw the scene by normal passage, and hope can have a kind of rapid safety from the downfall equipment of self-help escape outside window.

The purpose of this utility model provides a kind of high building simple in structure, esy to use, safe and reliable and catches fire safety from asking downfall equipment.

The utility model is achieved in that cable drum is installed in downfall equipment, be wound with the steel wire rope that is used to hang personal weight thereon, for weight can at the uniform velocity be descended, be provided with two corresponding mutually inclined-plane fixed friction pieces in the cable drum bottom, between two inclined-plane fixed friction pieces, be provided with movable brake pad, be gripped with steel wire rope between movable brake pad and the inclined-plane fixed friction piece, on movable brake pad, be provided with displacement plate, this activity brake pad connects with displacement plate is anterior, movable brake pad can adopt four groups eight, the one end is hinged with displacement plate respectively, its the other end is located hinged respectively, steel wire rope is by between fixed friction piece and the movable brake pad, when displacement plate moves, can produce corresponding the rotation by drive activity brake pad, make its both ends produce corresponding pressure to steel wire rope, thereby increase frictional force, restriction steel wire rope decrease speed to steel wire rope; Move for driving displacement plate, be connected with the displacement pinch roller at the displacement plate middle part, the displacement plate rear end is mounted with anti-displacement plate, and this anti-displacement plate connects with movable friction member by spring; At the uniform velocity descend under the weight effect for controlling steel wire rope, in downfall equipment, be provided with the control ratchet, its underpart is provided with control piece, the fast connector of control and controls fast movable brake pad, this controls fast connector rotating support, and touch with the fast part of control, the fast movable brake pad of control respectively, this is controlled fast part upper end and touches with ratchet on the control ratchet, controls simultaneously that a side is provided with reel control speed part on the ratchet, and the ratchet on the control ratchet is hung with the elbow of reel control piece lower end and joined.

Be socketed with driving lever on reel control piece top, its middle part rotating support, projection on the driving lever other end and the fast part of center folder control touches, on the fast part circumference of center folder control, be laid with folder, this folder front end is provided with chuck, collet rear is by axle rotating support folder, be provided with slotted eye at the folder rear portion, be with projection in its slotted eye, this projection and the center fast part of folder control are fixedly connected, and center folder fast part of control and cable drum are installed on the same axle, when the control ratchet rotates, driving the reel control piece simultaneously moves down, drive reel center folder control piece by driving lever and produce intermittently reciprocating motion, chuck is clamped spool shaft loosen motion repeatedly, thereby controlling the rotary speed of spool shaft, the steel wire rope gliding speed is well controlled, reaches the influence that overcomes acceleration of gravity.

Movable friction member middle part is that rotating support connects, and guide wheel is equipped with in its front portion, and its rear portion is connected with spring, the other end of this spring connects with anti-displacement piece rear end, this anti-displacement piece middle part rotating support connects, and its anterior projection with the displacement plate rear end articulates, and makes itself and displacement plate produce interlock.

When weight by steel wire rope when the lower slider, steel wire rope is to the corresponding generation pressure of displacement pinch roller, this displacement wheel pressing shaft is in the recessed bearing, hole, make the displacement wheel pressing shaft drive displacement plate and produce certain displacement, simultaneously, drive activity brake pad produces corresponding rotation, therefore, movable brake pad and fixed friction piece are just to the certain pressure of the corresponding generation of steel wire rope, be the certain frictional force of corresponding generation, restriction steel wire rope sliding speed, if weight is heavy more, steel wire rope also strengthens the pressure of displacement pinch roller thereupon, then the frictional force of corresponding generation is also just big more, simultaneously can automatic synchronization and feedback, when steel wire rope is taken turns by control, the control wheel just rotates thereupon, make control piece and the control fast movable brake pad, also just produce intermittent movement thereupon, so just further control the sliding speed of steel wire rope regularly, make it at the uniform velocity to descend, when displacement plate moves, driving anti-displacement piece simultaneously rotates, make the extension spring that connects with it produce corresponding pulling force, the friction member that innervates has also increased frictional force to the corresponding increase pressure of steel wire rope, strengthen the sliding speed that has limited steel wire rope simultaneously, in addition, when the control wheel rotates, also drive the reel control piece simultaneously, reel center folder control piece produces intermittent movement, controlling the rate of release of steel wire rope closely, weight is at the uniform velocity slowly descended.

The utlity model has advantages such as simple in structure, esy to use, safe and reliable.

Below in conjunction with accompanying drawing the utility model is done to describe.
