The fixing can be realized by welding or bolting. One embodiment of the support seat 14 is a tubular fixed to the outer casing 10. In the other embodiment of the present invention, the support base 14 may be a plurality of block members (not shown) dispersed on the inner side wall surface of the tubular housing 11.

The pulley 20 is rotatably pivoted to the first end cover 12, and the pulley 20 has a cable groove 21, and the descending cable 40 for hanging the person descending is wound around the cable groove 21 (see FIG. 4). Both ends of the 40 can be used for hanging the person to descend, and the pulley 20 is driven to rotate while the descending cable 40 descends. In an embodiment of the present invention, the wall surface on which the cable groove 21 and the descending cable 40 are in contact has a plurality of protruding ribs 22, which can increase the frictional force of the descending cable 40 and the pulley 20.

In an embodiment of the invention, the outer casing 10 has an introducer 30 for guiding the descending cable 40 around the pulley 20 into and out of the outer casing 10, and increasing the contact length of the descending cable 40 with the pulley 20, as shown in FIG.

The two guide pulleys 32a and 32b are spaced apart from each other by a distance d1 to form a guide for the descending cable 40 to enter and exit the outer casing 10. The guiding path P further has a first guiding hole 311 and a second guiding hole 312. After the descending cable 40 passes around the pulley 20, both ends of the descending cable 40 pass through the two guiding pulleys 32a. The guiding path P between the two guiding holes 311 and the second guiding holes 312 passes through the fixing base 31 respectively, wherein the distance d1 between the two guiding pulleys 32a and 32b is smaller than the groove of the pulley 20 The diameter D1 of 21 allows the descent cable 40 to have a longer contact length with the cable groove 21 when it is wound around the pulley 20 to increase its friction.

The planetary gear mechanism includes a ring gear 50 and a plurality of planetary gears 51. In one embodiment of the present invention, three planetary gears 51 are included. The ring gear 50 is fixed to the inner wall surface of the tubular casing 11, and the ring gear 50 is a kind. The ring member has a plurality of continuously arranged tooth portions 501 on the inner diameter wall surface of the ring gear 50.

At a concentric circumferential position of the side wall of the pulley 20, the planetary gear 51 meshes with the tooth portion 501 of the inner wall surface of the ring gear 50, and the planetary gear 51 can move along the inner diameter of the ring gear 50 while rotating with the pulley 20 while rotating. By the gear ratio of the ring gear 50 and the planetary gear 51, when the pulley 20 rotates one turn, the planetary gear 51 is rotated more than the number of turns, in other words, the rotational speed of the planetary gear 51 is greater than the rotational speed of the pulley 20, and the effect thereof is obtained.

The rear end of the hole 731 is closed, the elastic member 74 is first loaded into the hole 731, and the slider 72 is slidably The hole 731 is loaded, and the slider 72 is pushed by the elastic force of the elastic member 74, so that the roller 71 pivoted at the front end of the slider 72 can continuously touch the inside of the deceleration ring 60 during the rotation of the turntable 61 of the speed reduction mechanism. The radial wall surface 601 generates a damping effect by the interference between the roller 71 and the inner diameter wall surface 601 of the deceleration ring 60, and further decelerates by the planetary gear mechanism interlocking the pulley 20, thereby achieving the purpose of reducing the descending speed of the descending cable 40.

In an embodiment of the invention, the speed reduction mechanism often maintains the roller 71 of at least two dampers 70 in contact with the inner diameter wall surface 601 of the deceleration ring 60. In one embodiment as shown in FIG. 1, there are three dampers 70, During the rotation of the turntable 61 of the speed reduction mechanism, the roller 71 of at least two dampers 70 is often kept in contact with the inner diameter wall surface 601 of the deceleration ring 60, but if the roller 71 of the damper 70 is all during the rotation of the turntable 61 of the speed reduction mechanism Both of them are in contact with the inner diameter wall surface 601 of the deceleration ring 60, so that a large damping effect can be produced; in an embodiment of the invention, the roller 71 of the at least two dampers 70 and the inside of the deceleration ring 60 are often maintained. The radial wall surface 601 is in contact, and one embodiment means that the roller 71 of the damper 70 is caught in the trough position of the continuous wavy inner diameter wall surface 61 to produce a large damping effect.

The inner diameter wall surface 601 of the deceleration ring 60 is in contact.

In an embodiment of the present invention, the planetary gear mechanism serves as a transmission mechanism between the pulley 20 and the speed reduction mechanism, and the ratio of the gears between the planetary gear 51 of the planetary gear mechanism and the ring gear 50 allows the pulley 20 to pass through while rotating. The planetary gear mechanism drives the turntable 61 of the speed reduction mechanism to rotate at a faster rotational speed than the rotational speed of the pulley 20. In other words, the rotational speed of the rotary disk 61 will be greater than the rotational speed of the pulley 20, so that it can be fixed to the turntable every time the pulley 20 rotates once. The roller 71 of at least two dampers 70 of 61 can generate more interference with the inner diameter wall surface 601 of the deceleration ring 60, and then the pulley 20 is coupled to the pulley 20 to generate a deceleration effect, thereby reducing the descending speed of the descending cable 40. the goal of.
