The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
With reference to accompanying drawing 1-4, guide wheel shaft 1, central shaft 5 are riveted on respectively on the bearing 3, and guide wheel 2 is placed on the guide wheel shaft 1, and the guide wheel cover plate is riveted on the guide wheel shaft 1.Driving rope sheave 4 is placed on the central shaft 5; Driving rope sheave 4 is provided with and is used to twine the slow V-arrangement grooving that falls rope 8; And drive rope sheave 4 and three planetary wheel carriers and be configured to one; Three planetary gears 6 are fixed on the planetary wheel carrier through the hex screw 9 of hexagonal in locking pad 7, the band respectively, and a sealed step of hexagon wherein is installed on the right side of planetary gear 6, and a copper locking pad 7 is set on this step; Soket head cap screw 9 with 0.2 millimeter round boss of locking pad 7 usefulness is fixing, to reach locking sealed purpose.Central gear 17 is formed as one with the friction catch wheel, and is installed on the central shaft 5 through bearing 22, and bearing 22 leans on collar 19 location.Four centrifugal friction pieces 16 are processed by brass, place four grooves on the friction catch wheel respectively, and are as shown in Figure 1.Gear ring 10, phase-change material case 18 are fixed on the bearing 3 through bolt 11, are filled with phase-change material 15 in the phase-change material case 18, and phase-change material can be a calcium chloride.Shell 24 is fixed in the right side of central shaft 5 through screw 20, pad 21.Suspension ring 12 are fixed on the bearing 3 through bolt 13.The slow rope 8 that falls is walked around guide wheel 2 and is wound in the V-type grooving that drives rope sheave 4 and lays out from the guide wheel 2 of the other end.Suspension strop 14 walk around suspension ring 12 suspension be installed in below balcony, the windowsill or the supporting support of front, roof on.
