The specific embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1.On three faces of the U-shaped frame 16 forming with Plate Welding, bore respectively several holes.U-shaped frame 16, by its base apertures, is fixed near the metope 6 of window with expansion bolt 4.
Relatively two pairs of holes of both sides are concentric, and the meshed center distance of the two pairs of hole heart distances and gear 2 14, gear 1 equates.Wherein a side of pair of holes and the seam of motor 1 coordinate, and the seam of opposite side and magnetic powder brake 7 coordinates, and is fixed in U-shaped frame 16 by screw 22,9.Gear 1 is installed on the axle of motor 1, and is located by screw; The axle head of the axle head of magnetic powder brake 7 and motor 1 is linked together by shaft coupling 5, and with screw 8 tightenings.In the another pair of holes of U-shaped frame 16, thread spindle is installed, reel 12, bearing 11, and gear 2 14 and axle sleeve 10,15, wherein thread spindle is to be threaded and to be formed by thread spindle top 13 and thread spindle bottom 20 use, the two ends of thread spindle are fixing with U-shaped frame 16 with nut 21; Axle sleeve 10 and axle sleeve 15 withstand on the inner ring of bearing 11, and the outer ring of bearing 11 coordinates with endoporus and the gear 2 14 of reel 12 respectively, and Positioning Gear 2 14, realizes the engagement of gear 2 14 and gear 1.
On another place's metope, with expansion bolt 19, fixed fixed pulley 17.The position of fixed pulley 17 and reel 12 are corresponding.
Rope 18 is wrapped on reel 12, and an one termination is fixed in the hole on the disc of gear 2 14.Rope 18 is walked around fixed pulley 17, and another termination and fake 23 are fixed together.
The electric wire of motor 1 is connected as shown in Figure 2 with the electric wire of magnetic powder brake 7.The electric wire of motor 1 and magnetic powder brake 7 parallel connections, and slide rheostat 24 is set on loop; Motor 1 is connected with power supply 26 by dibit commutator 25.
When fire occurs, people jumps out escape from window with it fake 23 can being fixed on.When people's gravity pulls rope 18 to fall downwards, be wrapped on reel 12 that rope 18 unclamps and driven gear 2 15 rotations, gear 2 14 driven gears one 3 rotations, now motor 1 is in generating state, and produces the decline that electromagnetic damping hinders people; Motor 1 electricity is supplied with the electromagnet of magnetic powder brake 7, produces magnetic, and produces the decrease speed that brake force further hinders people.The people who makes like this escape while landing speed not high, can be not injured.
