Abstract

The utility model relates to a self-life saving cableway for fire. A base seat is arranged in a casing; locking blocks of a slider are arranged on the base seat via a locking block shaft; pulley wheels are arranged on the base seat via a wheel shaft; steel cables pass by the pulley wheel and the locking block of the slider. When buildings caught fire, the upper end of the steel cable is fixed to some point near a window, and a safety belt which is sheathed on the human body is fixed to the casing of the self-life saving cableway; the locking block of the slider locks the steel cable when the human body is sliding down along the steel cable, and a handlebar on a locking block shaft is wrenched when need sliding down; the human body glide smoothly and slowly along the steel cable when the steel cable is loosened. The utility model with the advantages of high safety of use and convenient operation can evacuate people from the fire site successfully.

Description

The fire self-rescue cableway

The utility model belongs to firefighting security device.

During the high-rise breaking out of fire, the personnel that evacuate in the building are unusual important problem, and are very difficult from the corridor evacuation because pyrotechnics fills the air in the building, and from being a kind of ideal method to ground under the window.Withdraw general employing pulley and rope is reduced to ground with personnel from window at present, but the method personnel are difficult to handle, have the hidden danger of personnel's fortuitous casualty, rope is easily blown by raging fire in addition.

The purpose of this utility model is to provide a kind of easy to operate, safe and reliable, guarantees the Self-life saving cableway that personnel withdraw from the scene of fire in the building.

Solution of the present utility model is to install a pedestal in the enclosure, the slider lock dog is installed on the pedestal by the lock dog axle, two pulleys are contained on the pedestal by wheel shaft separately, steel wire rope is at first walked around two pulleys, be the shape of falling S again and walk around the slider lock dog, the lock dog axle is connected with handle, and deceleration device is equipped with at the pulley place.When in the building during breaking out of fire, steel wire rope upper end is fixed near the somewhere window, the safety belt that will be enclosed within again on the human body is fixed on the Self-life saving cableway shell, when human body is suspended in outside window, because gravity own rotates counterclockwise the slider lock dog, slider lock dog and base wall are pinned steel wire rope automatically, move handle with the hand clockwise direction when needing to glide, the slider lock dog leaves base wall, because the deceleration of pulley, human body slowly steadily glides along steel wire rope, if personnel need rest on a certain position, release handle, steel wire rope is lockable automatically once more.

The utility model is safe and reliable, and is easy to operate, simple in structure, and self-locking performance is strong, the scene of fire personnel can be withdrawn smoothly.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the utility model cutaway view;

Fig. 2 is the utility model sectional view.

The utility model is made up of steel wire rope 2, shell 10 and pulley 7, installing pedestal 1 is equipped with lock dog axle 4 on the pedestal 1 in shell 10, and slider lock dog 3 is arranged on the lock dog axle 4, each is fluted for lock dog axle 4 and slider lock dog 3 corresponding positions, by key 5 both are fused, pulley 7 is installed on the pedestal 1 by wheel shaft 8, can establish two pulleys 7, steel wire rope 2 is walked around pulley 7, be the shape of falling S again and walk around slider lock dog 3, slider lock dog 3 is provided with pressure ring 6, can prevent steel wire rope 2 plaies.Shell 10 is provided with fixator 9, and fixator 9 can be fixed on safety belt on the shell 10, and fixator 9 can be gap, hook or a collar.On the pedestal 1 of pulley 7 corresponding sections, be fixed with pad 11, between pad 11 and the pulley 7 butterfly spring 12 arranged, brake block 13 is housed on the pulley 7, deceleration tooth 15 is arranged in the groove of pulley 7, wheel shaft 8 is connected with handle 14, and locking tooth 16 is arranged on the slider lock dog 3, and steel wire rope 2 can be the nickel coated steel wire rope.Butterfly spring 12, brake block 13, deceleration tooth 15 gliding speed that can slow down wherein, locking tooth 15 can increase the degree of blocking of 3 pairs of steel wire ropes 2 of slider lock dog.
