Abstract
The utility model discloses a safety lifesaving slow-lowering device. A roller spindle of a roller device of the safety lifesaving slow-lowering device is fixed to walls of both sides of the casing; brake damping tapes which are arranged on the inner wall of the casing are provided by flanges which are corresponding to both ends of the roller; a steel cable of the brake damping tape is fixed to a connecting plate; the steel cable which is arranged on the roller is led out after passing by a small shaft which is arranged between two connecting plates via an opening of the casing; one end of a coil spring which is arranged in the roller is arranged on the inner wall of the roller, and the other end is fixed to the roller spindle. The utility model can regulate the damping automatically according to the weight and can ensure the safety. The lifesaving slow-lowering device returns automatically after the saved person is left, and is suitable for the self aid of trapped persons in high buildings.
Description
The utility model relates to a kind of safe life-saving descending lifeline.
In recent years, China's city-building develops rapidly, and flickering high buildings and large mansions are rised sheer from level ground, office building, restaurant and dormitory building have increased a lot, not only satisfied the needs of China's tourism development, many residents have moved into the new home, and resident for a long time progressively is eased in housing problem.But when high-rise building generation disaster accident, as fire, earthquake; Disaster affected people is fled from the disaster area, and rescuing lives and properties does not also have instrument preferably.
The purpose of this utility model is that in time flee from the disaster area when solving high-rise building generation disastrous accident and rescue that lives and properties design a kind of comprises the safe life-saving descending lifeline that disc spring debooster, brake deceleration mechanism and wire rope drum mechanism form; Simple in structure, safe and reliable.
The utility model content, the drum shaft of the drum apparatus of safe life-saving descending lifeline is fixed on the two side of shell, between cylinder and drum shaft bearing is housed, inner wall of rotary drum corresponding to the flange at cylinder two ends is provided with the brake damping tape, the steel wire rope that is connected with the brake damping tape is walked around the roller on the connecting rod rest and is fixed on the projection of connecting plate, and an end of connecting plate is hinged on the connecting plate frame; Be loaded on steel wire rope on the cylinder and walk around on the little axle that is contained between two connecting plates through the opening of shell and draw, disc spring is housed in the cylinder, an end of disc spring is contained on the inwall of cylinder, and the other end of disc spring is fixed on the drum shaft.
Be loaded on little axle sleeve between two connecting plates the axle sleeve of pulley action has been housed; Be loaded on steel wire rope on the connecting plate by being contained in the tightening of connecting plate screwing.
The utility model advantage, the safe life-saving descending lifeline can be according to by rescue worker's body weight, axle sleeve on the little axle of the steel wire rope on cylinder pushing changes the size of damping, control personnel decrease speed automatically, guarantee safety, disc spring when being descended by the rescue worker in the cylinder tightens up, and after leaving when being rescued by the rescue worker, because the spring restoring force of disc spring, automatically will receive on the steel wire rope, used by the rescue worker for next; Between cylinder and drum shaft rolling bearing is housed, so the cylinder rotation is light flexibly, the rope on the cylinder adopts steel wire rope, and intensity is good, and can use in fire.
Description of drawings:
Fig. 1 is the utility model front view (vertical view);
Fig. 2 is the A-A cutaway view of Fig. 1;
Below in conjunction with the preferred embodiment of description of drawings the utility model, the drum shaft 1 of safe life-saving descending lifeline is loaded on the two side of shell 3 and with nut and fixes, rolling bearing 2 is housed between cylinder 7 and the drum shaft, cylinder is rotated flexibly, flange 4 corresponding to the cylinder two ends is provided with brake damping tape 5 on the inwall of shell, draw through the opening 9 of shell with the steel wire rope 8 that the brake damping tape is connected, walk around the roller 10 on the connecting plate frame and be fixed on the connecting plate 13, one end of connecting plate is hinged on the bottom of connecting plate frame 11, the steel wire rope 16 that is loaded on the cylinder is drawn through the opening 9 of shell, the axle sleeve of walking around on the little axle 15 hangs down, little axle is loaded on a left side, in the hole of right two connecting plates 13, the outer end of little axle is spacing by pin, connecting plate 13 is provided with projection 17, steel wire rope 8 pass on the projection aperture and by screw 17 tightenings, can adjust the damping of braking between damping tape 5 and the flange 4 when unclamping screw 17, rescued personnel's speed of fall with control, adjustment finishes with screw 17 steel wire rope 8 tightenings, two disc springs 6 are housed in the cylinder, the dimensions and the parameter of two disc springs are identical, coil direction too, an end of disc spring is installed on the inwall of cylinder, the other end of disc spring is fixed on the drum shaft.Steel wire rope 16 is loaded in the groove of cylinder surface setting, so the steel wire rope marshalling is beneficial to use.The shell of safe life-saving descending lifeline is provided with two otic placodes 12, the utility model can be fixed on the wall of building through screw-nut.
