Description

Skyscraper resident cable elevator

The utility model is when being used for skyscraper generation danger and disaster situation, a kind of small mechanical equipment of safe falling.

Along with the continuous growth of China's demographic and economic, the resident who lives in the city in the skyscraper is more and more.And in the skyscraper generally all by elevator is housed, for people's discrepancy provides great convenience.But, danger and disaster situation such as fire, earthquake, artificial injury etc. are appearring, and people just can't escape dangerous condition by elevator.A kind of ejection type parachute that is applicable to skyscraper is arranged abroad, but the danger that the survivor is injured by car takes place the time marquis who falls earthward in easily; The patent No. is 94211686.0 human body lift clutchs at home, and he is by survivor's two hand handles that shake, and by the chain sprocket drive principle, realizes the purpose of personal automatic lifting.But this device can only be for people escape, and under the situation of the many person-times of escapes in same place, this human body rises the slurry device automatically with powerless.

The purpose of this utility model is at above-mentioned deficiency, and a kind of processing ease is provided, and landing is rapid, the skyscraper resident cable elevator of many person-times of uses.

Task of the present utility model is finished as follows:

When danger and disaster took place, if a people descends from skyscraper, the free end that then will twine the rope on the cylinder lay on the support, and link is lain on one's body the descender.Follow the operating control of operational brake, the drg brake off, the descender is landing downwards under the effect of health deadweight.This moment, cylinder rotated, and hinge wheel drives minor sprocket by messenger chain, rotates together thereby also drive the drg rotating part.Corrective action is actuating force on brake control device, can adjust descending speed, to guarantee its safely dropping.If many people when landing, then must hang on link on the support.First descender at first grasps and has been wrapped in that root rope on the cylinder, the speed that other personnel come brake activation device operating control adjustment landing person to descend.In this process, another root rope is twined again, and after first descender arrived ground, second person of falling just can grasp the rope that winding again comes up and begin landing .... when remaining last man-hour, can land with reference to aforesaid way.

The utlity model has simple in structure, processing ease, landing rapidly can many person-times of characteristics such as use.

Fig. 1 is the utility model integral structure figure.

Fig. 2 is the left view of utility model.

Below in conjunction with accompanying drawing the utility model is explained in detail:

Drg [5] comprises that rotating part [12] is supported on the brake axle [3] by bearing, fixed part [13] is fastening with frame [2], drg is in the first half of complete machine, rotating part [12] is an one with minor sprocket [4], operating control [10] is installed in the side of frame [2], two movable terminal one ends that comprise brake rod [16] are fixed with control wire [18], spring [7], the other end is fixed with brake cable [14], the top of brake cable [14] connects brake control lever [15], the cylinder [19] that is wound with rope [8] is supported on drum shaft [9] by bearing, be installed in the lower part of frame [2], in order to realize the power transmission between rotating part and the cylinder, can adopt chain gear or gear transmission, when using chain gear, hinge wheel [7] combines as a whole with cylinder [19], minor sprocket [4] combines as a whole with rotating part, hinge wheel [7] and minor sprocket [4] and same messenger chain [6] engagement, when adopting gear transmission, miniature gears is fixed together with the rotating part of drg, big gear wheel is fixed together with cylinder, and the two meshes transferring power by gear tooth, it is track adjusting wheel [20] that the top of frame [2] has link [1] lower curtate, cylinder [19] is gone up and is twined two ropes [8], the winding direction of two ropes is opposite, and with dividing plate with two ropes separately.

When causing danger situation, if descending from skyscraper, a people then the free end that is wrapped in the rope [8] on the cylinder [19] is lain in support, link [1] is lain on one's body the decline personnel, at this moment, because normally closed spring [17] is by brake rod [16], brake cable [14], brake control lever [15] and brake shoe expander, overcome the restoring force of the pull back spring in the drg [5], the brake shoe brake cheek [11] that is bearing on the drg fixed part [13] is pushed against with drg rotating part [12], cause drg [5] to be in braking mode, descended the rope [8] of personnel's body weight effect by cylinder [19], messenger chain [6] has the trend of rotating part [12] rotation that makes drg, can be owing to drg [5] be in braking mode, so personnel can not fall.After the descender spurs control wire [18], normally closed spring [17] is stretched, brake rod [16] rotates, brake cable [14] is pulled under the effect of drg [5] in-to-in pull back spring, brake control lever [15] and brake shoe expander also rotate under the pull back spring effect, application force between brake shoe brake cheek [11] and the drg rotating part [12] reduces at this moment, drg [5] is thrown off, the descender is landed under the effect of self body weight, the decline personnel can be according to the velocity magnitude that descends, adjust the size of the power of pulling control wire [18], to keep its safely dropping.In this process, another root rope is twined by cylinder [19] again, if many person-times when descending, then need link [1] is hung on a thing, first descender at first grasps the rope [8] that has been wrapped on the cylinder [20], the operating control [10] of other personnel's brake activation device [5], the size of regulating braking force according to the rotation speed of cylinder [19].When first descender arrives ground, the other staff on the building just can grasp is twined the rope [8] that comes up again by cylinder [19] and descends.
