The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated structure.
As shown in Figure 1, the structure of portable high-building lifesaving appliance of the present utility model is to utilize the bicycle brake technology, employing includes a pulley of A, the B end of making of aluminium alloy, be formed with wire casing between the brake lining 17,18 of pulley A, B end, on described pulley A end, be provided with adjustable brake gear, on described pulley B end, be provided with hand brake device; Periphery at described pulley A, B end is provided with shell 8 and 9, be enclosed with brake ribbon on the inner peripheral surface of described pulley A, B end, one of steel wire cable 1 is fixed in the groove of wire casing, and arrangement closely neatly is wrapped in the wire casing, stopping device is passed through in the other end of steel wire cable 1, pass directed roller 2 and retaining frame 23, and stamp retaining lead sealing 24.Bottom between pulley A, B end housing is provided with hook rack 22, can play the effect that is connected and fixed pulley A, B end housing.
Hold a side to be provided with A at pulley A and hold adjustable brake gear, its structure is by the bolt type connecting rod, by pulley A end housing end direct through groove, regulate 16 terminal connections of fixed head with brake ribbon, brake ribbon is regulated the top and the pulley A end housing end face of fixed head 16 and is fixed with screw.Assort mutually with pulley A end this moment.Adjusting yoke 12 is fixed on the adjusting fixed head 16 by regulating stage clip 15 and regulating indicating piece 14, screw compressing stage clip 15 by adjusting nut 13, show by regulating pointer 19, make it to produce the friction dynamics that tension force comes towing brake band and aluminium alloy pulley A end, the weight that changes the person (freely falling body) plays the auxiliary brake effect to the 10-15 kilogram.
Hold a side to be provided with B end hand brake device at pulley B, principle and bicycle identical, be provided with brake in this device 11, an end of brake cable 10 is connected end with brake, and the end face groove 25 that the other end of brake cable 10 passes pulley B end housing 9 is connected with pulley B end housing 9.
Stopping device in this device includes installs the two directed supports 26 that are clipped between the described fixed head 20,6, by pin bolt 3 directed roller 2 and retaining support 23 are fixedly clamped, described steel wire cable 1 passes retaining support 23 by directed roller 2, and load onto retaining lead sealing 24, prevent steel wire cable 1 retraction.Because the steel wire cable that adopted is that intensity and toughness are elastomeric by force, carry simultaneously also to put out a fire, lifesaving runs up and down, steel wire cable 1 inevitable resilience is loosening, makes to twine and the rope confusion of marshalling, goes out danger easily.Therefore, the rope that must block marshalling can not be loose, need be when passing retaining support 23 by directed roller 2, and steel wire cable 1 is stamped retaining lead sealing 24, makes it to bounce back, and regulate brake this moment must be more than 20 kilograms.The people descends in the time of owing to people and lifesaving appliance when using this lifesaving appliance, and retaining lead sealing 24 rests on the steel wire cable 1, and this moment, retaining support 23 was through finishing mission.But owing to be lifesaving, the staff also will rest on next floor relief or carry out other task, requires the steel wire cable 1 still can not be chaotic.Therefore the retaining sheet 4 in the described stopping device and fixed head 6 they be that mode with hinge is combined on bearing pin 7 and the spring 5, retaining sheet 4 upper ends are provided with tough mouthful that grinds, its hardness reaches more than the HRC55 degree through quenching.Under the effect of spring 5 and certain position, make steel wire cable 1 can only export and can not bounce back, keep steel wire cable 1 proper alignment in wire casing, reach safe decline purpose.
Described steel wire cable 1 oppositely is passed in the directed roller 2 that directed support 26 sides are installed, and makes steel wire cable 1 perpendicular to described central shaft 21.Be wrapped in steel wire cable 1 end (being fixed on building steam heating pipe or other fixtures) on the wire casing between pulley A, the B end, it is an off plumb to the axle center, it must cause departs from inclination, because directed roller 2 in directed support 26 sides installation, the pulley that steel wire cable 1 is made by described aluminium alloy oppositely passes directed roller 2, the direction of steel wire cable 1 output can not keeping perpendicular to central shaft 21 and decline object always, thereby guarantees the safety and steady of decline.
