Abstract
The utility model provides a slowly-lowering life-saving device for a high-building. The utility model comprises a reel which is provided with a rope and can rotate around a shaft, and a damping device which provides resistance to the reel, wherein, the damping device has a braking mechanism and a retarding mechanism. In the braking mechanism, a ratchet wheel is coaxially fixed with the reel, and a ratchet pawl is arranged on the reel frame and matched with the ratchet wheel to stop the reel. In the retarding mechanism, the reel frame is provided with an operating rod, and the frictional force between the damping element and the reel is controlled by the operating rod. The utility model not only has high security and reliability, but also can conveniently control the descending speed. Meanwhile, the utility model has the characteristics of simple and compact structure, and low cost.
Description
A kind of high building is slow to fall brucker survival capsule, relates to device use for taking people downstairs on building or the analog.
Chinese patent application discloses for No. 92206650.7 a kind of " friction braking high-altitude downfall equipment ", use the canine tooth wheel disc transmission one of constant velocity spiral cloth tooth to be assembled in little gear on the arrestment mechanism dish guide rod, make its compression spring produce elastic force and act on brake pad formation moment of friction, thereby offset the moment that human body gravity produces, by controlling the mode of moment of friction effectively, downfall equipment is descended by the needed speed of people or stop operation in the air.Yet this downfall equipment is given pinion by the transmission of canine tooth wheel disc, and then brakes, and therefore, arrestment mechanism is stressed greatly, and security and reliability are affected.
The purpose of utility model provides the slow brucker survival capsule that falls of a kind of high building, and its can delay reliable and securely and falls.
According to above-mentioned purpose, utility model adopts such technical scheme: this high building is slow to fall the damping unit that brucker survival capsule comprises band rope and the reel that can rotate around the axis and resistance is provided to reel.Be characterized in that damping unit is divided into braking mechanism and reducing gear two parts.In the braking mechanism, ratchet and reel are coaxial fixing, and ratchet is installed on the reel stand and cooperates with ratchet reel is braked; In the damping mechanism, control stick is housed on the reel stand, and by the frictional force between control stick control damping piece and the reel.
The utility model is equipped with braking mechanism and reducing gear simultaneously, has promptly improved security, reliability, can make things convenient for again to control decrease speed freely.Simultaneously, control, also have characteristics simple in structure, compact, that cost is low by ratchet, ratchet, control stick, damping piece.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 falls the brucker survival capsule structural representation for delaying according to the high building that the utility model proposes.
Fig. 2 is for braking and the reducing gear structural representation according to the slow brucker survival capsule that falls of the high building that the utility model proposes.
Below in conjunction with drawings and Examples to falling brucker survival capsule and be further described according to the high building that the utility model proposes is slow.
As shown in Figures 1 and 2, be wound with rope (2) on the reel (1), spool shaft is installed on the support (4), and rope can carry out folding and unfolding when reel sways.Damping unit can be controlled the rotation of reel, and it is made up of braking mechanism and reducing gear two parts.Braking mechanism is by constituting with co-axially fixed ratchet of reel (3) and ratchet.Ratchet (4) is installed on the roller stand, and when ratchet and ratchet mutually during interlock, reel stops operating; When ratchet and ratchet were separated, reel swayed.One end of ratchet is with the interlock of ratchet phase, and the other end is handle (10), so that the user handles.There is an end of handle preferably to be with spring (5) at ratchet,, makes ratchet and ratchet interlock mutually by spring when ratchet in the raw the time.Want releasing of brake, need only handle down.
Reducing gear is made of control stick and damping piece.Control stick is installed on the reel stand, and damping piece provides resistance for reel and controlled by control stick.In the present embodiment, damping piece is a pair of endless belt (8), and it is enclosed within on the reel.Control stick (6) end is between endless belt and reel.When drop-down control stick, the endless belt is tensioned, and damping action is played in the rotation of reel.Preferably also load onto spring (7) between control stick and the support, make the endless belt be in relaxed state at ordinary times like this.During use, safety belt is tied up to the other end of control stick, the people then ties up on the safety belt.Because the weight of human body self makes the endless belt be tensioned, reel is produced resistance.If will stop to descend, then unclamp ratchet, make ratchet and ratchet interlock mutually, reel promptly stops operating.
In another embodiment, damping piece also can be block, as nylon block or blob of viscose etc.This bulk damping piece is fixed on control stick or the reel, regulates the degree of closeness of control stick and reel, i.e. frictional force between adjustable block shape damping piece and reel.
Claims (5)
1, the slow brucker survival capsule that falls of a kind of high building, the reel that includes the band rope and can rotate around the axis reaches the damping unit that resistance is provided to reel, it is characterized in that damping unit is divided into braking mechanism and reducing gear two parts, in the braking mechanism, ratchet and reel are coaxial fixing, and ratchet is installed on the reel stand and cooperates with ratchet reel is braked; In the damping mechanism, control stick is housed on the reel stand, and by the frictional force between control stick control damping piece and the reel.
2, high building is slow according to claim 1 falls brucker survival capsule, it is characterized in that damping piece is the endless belt that is enclosed within on the reel, and the control stick end is between endless belt and reel.
3, high building as claimed in claim 1 is slow falls brucker survival capsule, it is characterized in that damping piece is fixed on control stick or the reel.
4, high building is slow as claimed in claim 1 or 2 falls brucker survival capsule, it is characterized in that being equipped with on the ratchet spring.
5, high building is slow as claimed in claim 1 or 2 falls brucker survival capsule, it is characterized in that being equipped with on the control stick spring.
