The hydraulic slow drop device mainly is made up of speed control and rope sheave mechanism.Speed control mainly is made up of planetary gear speed increasing mechanism and hydraulic pressure reducing gear two parts, as shown in Figure 5, gear up mechanism wherein is a secondary planetary gear transmission mechanism, mainly by external tooth centre wheel 41, interior toothed ring gear 20, central wheel of internal teeth 46, asteroid wheel 18, major planet wheel 19, pivoted arm 39 and power shaft 11, power transmission shaft 43 is formed, centre wheel 41 is connected with axle 43 by key 40, centre wheel 20 is connected with the speed control housing by pin 42, centre wheel 46 is connected with axle 11 by screw thread, asteroid wheel 18, major planet wheel 19 links to each other with axle 21 by key 17, and be connected with pivoted arm 39 with bearing 22 with bearing 16 by axle 21, pivoted arm 39 is supported on the axle 43 by bearing 38 and bearing 44, and centre wheel 46 is meshed with planetary gear 18, interior toothed ring gear 20, external tooth centre wheel 41 is meshed with planetary gear 19.Axle 11 is supported by rolling bearing 12 and rolling bearing 14, and rolling bearing 12 and rolling bearing 14 are positioned at bearing block 15, and axle 43 is supported by rolling bearing 37 and rolling bearing 45, and its middle (center) bearing 45 is positioned at the inside of axle 11.The hydraulic pressure reducing gear is mainly by drive end bearing bracket 32, the pump housing 26, rear end cap 24, driven gear 29, driving gear 35 and speed control valve are formed, gear 29 is connected with the axle 28 of gear hydraulic pump by key 27, gear 35 is connected with the axle 34 of gear hydraulic pump by key 33, axle 28 is supported on the pump body structure by needle bearing 25 and needle bearing 30, axle 34 is supported on the pump body structure by needle bearing 31 and needle bearing 36, driven gear 29, driving gear 35 is meshed, at driven gear 29, driving gear 35 surfaces, the inner surface of the pump housing 26, form the oil suction space of hydraulic pump between drive end bearing bracket 32 and the rear end cap 24 and press oily space, speed control valve is by control screw rod 48, push rod 50 and spring 51 move the size of controlling the damping hole of hydraulic oil in the circulating oil tank of flowing through, oil filler point 47, when being used to safeguard, steam vent 49 in the gear type hydraulic pump, injects hydraulic oil.The hydraulic pressure reducing gear is connected with the planetary gear speed increasing mechanism by rear end cap 24.Whole speed control 10 is connected with the framework 57 of rope sheave structure by housing 13.
Rope sheave mechanism mainly by wheel body 59, revolver along 52, right wheel along 58, left flywheel 54, right flywheel 60, wind spring 53, axle 55 and framework 57 form.A left side flywheel 54, right flywheel 60 with wheel body 59 and revolver along 52, right wheel is supported on the axle 55 along 58, utilizes left flywheel 54, right flywheel 60 folk prescriptions to the characteristics of transmission and the elasticity of wind spring 53, the rotation that realizes axle 55 is whether.Framework 57 and suspension hook 56 static line wheel constructions are on support.
Support uses with reference to Fig. 1, Fig. 2 and shown in Figure 3, for convenience of description, among the figure windowsill cut open, and be the origin of coordinates with windowsill outer and cantilever beam junction, the windowsill outer is an X-axis, and vertical direction is the Z axle, and being parallel to the cantilever beam direction is Y-axis, sets up space coordinates.Erect the position of pin 3 on cantilever beam 2 according to the adjustment of windowsill wall thickness before using, descending lifeline 8 is suspended on cantilever beam 2 annulus place outward, open perpendicular pin 3 and support bar 4 then, cantilever beam 2 is lain in a horizontal plane on the windowsill, at last transverse blocking-rod 1 is placed in the draw-in groove of cantilever beam 2 inner ends, and use bolting, and finishing installation, the user just can arrive safe ground by descending lifeline.Slow falling in the process, people's gravity almost all acts on the outer end of cantilever beam, it is the descending lifeline place, this gravity makes support be subjected to a torque along X-direction, make cantilever beam 2 that the trend of rotating around X-axis be arranged in the ZOY plane, and the interaction of perpendicular pin 3 and lateral ledge wall and transverse blocking-rod 1 and the inboard wall of windowsill has limited this trend.Transverse blocking-rod 1 interacts with the wall of the interior both sides of windowsill, has limited the motion that support rotates around the Z axle in XOY plane.In order to prevent that the slow cantilever beam 2 of falling in the process from rotate around Y-axis, designs one section quarter butt 7 in cantilever beam 2 and windowsill contact-segment.In sum, utilize the structure of support self structure and window that support is fixed on the windowsill reliably.In addition, cantilever beam 2 stretches out windowsill one segment distance during design, can guarantee that the escape personnel falls in the process away from wall slow, avoids causing casualties.As shown in Figure 1, the perpendicular position of pin 3 on the Y of cantilever beam 2 direction can be regulated with hinged sleeve 5, so this support can adapt to the wall of different-thickness.This support is easy to use, and is simple in structure, and dismounting can be taken off transverse blocking-rod 1 during storage easily, and perpendicular pin 3 and support bar 4 are folded up, and save the space.
When the body weight for humans masterpiece is used for rope 61, meeting driven wheel body structure and left flywheel 54, right flywheel 60 rotations, because left flywheel 54, the unidirectional delivery characteristic of right flywheel 60, drive axle 55 rotations, make wind spring 53 storage power simultaneously, and the axle 55 that drives speed control 10 rotates, axle 11 drives centre wheel 46, and through asteroid wheel 18, the acting in conjunction of major planet wheel 19 and centre wheel 20 is delivered to centre wheel 41 with rotation, centre wheel 41 drives axle 43, and through shaft coupling 23 with rotation be delivered to the gear hydraulic pump the axle 34, under the engagement of gear 29 and gear 35, the inner surface of the pump housing 26, rear end cap 24, drive end bearing bracket 32 and gear surface are divided into the pump housing oil suction space and press oily space, speed control valve on the circulating oil tank of offering on the pump housing is used for controlling the flow of oil of circulating oil tank of flowing through, and then adjust, the pressure of the hydraulic oil in control oil suction space and the oily space of pressure, thereby form counteractive adjustment to driven gear 29 and driving gear 35 rotations, control, this reaction is by the axle 34 of gear hydraulic pump, arrive axle 11 through shaft coupling 23 and Gear Planet Transmission structure function, thereby form reaction to axle 55, and then adjust, the rotating speed of control sheave shaft 55, thus realize rope sheave 59 at the uniform velocity running under different mass loadings.After the people arrives ground, because wind spring 53 stores the unidirectional drive characteristic of energy and left flywheel 54, right flywheel 60, wind spring 53 can drive rope sheave mechanism's backward rotation and can not drive the reducing gear motion of back, and rope is rewinded on the wheel body, uses ready for next time.
