In the utility model embodiment, as shown in Fig. 1, Figure 10, Figure 11, on described control handle 5, be installed with the 6th minor axis 51, the 7th minor axis 52, and on the 7th minor axis 52, roller 53 be installed.
In the utility model embodiment, as shown in Fig. 1 and Figure 12, described leverage is variable load plate 6, is shaped with the first circular hole 61, the second circular hole 62 and the second strip hole 63 on described variable load plate 6. The second circular hole 62 and the 3rd minor axis 13 on described variable load plate 6 are hinged, and its second strip hole 63 is sleeved on roller 53.
In the utility model embodiment, as shown in figure 13, described constant speed speed-limiting device 8 comprises shell 81 and is arranged on gear wheel 82, pinion 83, escape wheel 84 and the escapement lever 85 in shell 81, what described constant speed speed-limiting device 8 was also included in described shell 81 that four jiaos arrange is arranged on shell 81 screw hole 86 on substrate 1, described gear wheel 82 is coaxially fixed on constant speed wheel 2 and engages with pinion 83, described escape wheel 84 is coaxially fixed on pinion 83, and described escapement lever 85 is with the coaxial installation of gear wheel 82 and engage with escape wheel 84.
In the utility model embodiment, as shown in Fig. 1, Figure 14, on described L plate 9, be shaped with the 3rd circular hole 91, the 4th circular hole 92 and the 3rd strip hole 93. The 4th circular hole 92 and the second minor axis 12 on described L plate 9 are hinged, and described the 3rd strip hole 93 is enclosed within on the 5th minor axis 43 of pressing plate 4, and described the 3rd circular hole 91 is articulated with on the 6th minor axis 51 of control handle 5.
In the utility model embodiment, as Figure 1 and Figure 4, described constant speed descending lifeline also comprises backplate 15, described backplate 15 middle parts and described the 4th minor axis 14 ends are hinged, and described backplate 15 both ends oppositely offer U-lag 151, described U-lag 151 respectively with the axle 32 activity clampings of guide pad 10 central shafts and brake pad 3.
In the utility model embodiment, its working mechanism is: user hangs over body wt on the first circular hole 61 of variable load plate 6 by safety belt and connecting ring. L plate 9, control handle 5, variable load plate 6 can pass to pressing plate 4 by user's body weight, and by the transmission ratio of the adjustable user's body weight of control handle 5 power. Variable load plate 6 is equal to a lever, the second circular hole 62 is equal to the fulcrum of lever, operation control handle 5 can change the distance of roller 53 to fulcrum, in the situation that not pressing control handle 5, roller 53 can, automatically near fulcrum, now upload to the pulling force maximum of pressing plate 4 under the effect of human bady gravitational, otherwise, when user presses control handle 5, roller 53 during away from fulcrum, uploads to the pulling force minimum of pressing plate 4. Design the parameters such as suitable size, can realize at roller 53 and produce enough power during near fulcrum, make rope 7 be clamped and not produce slip (floating state) by brake pad 3 and pressing plate 4; At roller 53 during away from fulcrum, rope 7 produces slip (constant-speed descending state) starting between brake pad 3 and the gap of pressing plate 4 to slide and can not cause between rope 7 and constant speed wheel 2. As shown in figure mono-, figure tetra-.
In the utility model embodiment, because pressing plate 4 is relevant with user's body weight to the size of the frictional force of seizing generation on both sides by the arms of rope 7 to brake pad 3, and because constant speed is taken turns 2 constant speed effect, make the decrease speed of this constant speed descending lifeline not affected by user's body weight size, no matter the large fine descent rate of body weight all will be by desin speed constant-speed descending, has avoided the drop device of prior art that the generation of stall and other dangerous accidents easily occurs.
In the utility model embodiment, its using method is: rope 7 upper ends are fixed, and press above-mentioned wiring path wiring on constant speed descending lifeline, user hangs over health on the first circular hole 61 of variable load plate 6 by safety belt and connecting ring, depress the rear drop device of control handle 5 and start constant-speed descending with user, unclamping the rear drop device of control handle 5 can self-locking stop decline (hovering).
At embodiment mono-of the present utility model, as Figure 1 and Figure 4, when backplate 15 is horizontal, can carry out wiring or remove wiring operation, after backplate 15 rotating positioning closures, side-closed the entrance and exit position of wiring 7, in work, rope can not deviate from the groove 31 of brake pad 3 and guide pad 10.
At embodiment bis-of the present utility model, as shown in figure 16, adopt vertical layout, cancel guide pad 10 and L plate 9 in embodiment mono-, increased minor axis 12, minor axis 13 and be articulated with the backplate 11 on minor axis 12, when backplate 11 is horizontal, can carry out wiring or remove wiring operation. The structure of its center platen 4 is as shown in Figure 17, Figure 18.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting practical range of the present utility model, thus all equivalent variations of being done with content described in the utility model claim, within all should being included in the utility model claim scope.
