[specific embodiment]

With reference to accompanying drawing, a kind of high altitude rescue hydraulic slow drop utensil has a shell 1, the inside of this shell is equipped with main body 4 and is turned 3, in main body 4, be provided with 5,6,7,8 and four-way cockes of

piston

9,11, springs of damper piston of four band circle rollers 19 and adjust screw 12 and form buffering oil pockets 10; Be provided with two crisscross oilholes in the four-way cock 9, be provided with four crisscross oilholes in turning, turning, the round heart is a center line beyond 3, be fixed on the body shaft 13 by two bearings, the excircle of turning is provided with U type groove and gear, in the U type groove one deck friction material is arranged, its gear and pinion 2 engagements, pinion 2 is fixed on shell upper by the pinion shaft 2-1 that has rocking handle 2-2, be provided with gathering sill 18 in the bottom of shell, be provided with the directive wheel 14 of guide wheel shaft 17 in the gathering sill 18, directive wheel 14 both sides respectively are provided with an auxiliary guide wheel 15, bottom at shell is provided with gap, is provided with rope 16 in the gap.

During work, rope 16 enters from the gap of outer casing bottom, guide to 3 the right of turning again by the directive wheel 14 and the U type groove of the auxiliary guide wheel 15 in the left side, from right to left in multi-turn is being turned 3 U type groove, get off in the left side from turning, by the U type groove of directive wheel 14, draw again from gap with the auxiliary guide wheel 15 in the right.When left side rope bore the human body pulling force, directive wheel 14 pressed down auxiliary guide wheel 15 to the right in the effect of rope tension power, thereby compressed the other end of rope.Simultaneously, turn and 3 rotate 0 °～180 ° under the effect of rope pull, the 3 inboard flexible circle

roller action pistons

5,6 of crossing of turning make

piston

5,6 distribute downwards, move right.Hydraulic oil in oil pocket 5-1, the 6-1 is pressed towards 7-1,8-1 and buffering oil pocket 10 through four-way cock 9, and piston 3 produces pressure to turning on the other hand, turn 3 rotation of restriction.Because the efflux time of hydraulic oil and the control that flow velocity is subjected to switch 9,3 the rotating speed of therefore turning promptly is subjected to the control of switch 9, and

piston

5,6 is depressed into lower dead center from top dead centre successively in 0 °～180 ° process, and

piston

7,8 is depressed into top dead centre from lower dead center successively.When turning 3 when being rotated further 180 °～360 °, turn 3 inboard flexible cross circle

roller action pistons

7,8 make progress respectively, to left movement.Hydraulic oil is pressed into 5-1,6-1 and buffering oil pocket 10 through switch 9.In like manner, 7,8 pairs in piston is turned and 3 is produced pressure, turn 3 rotation of restriction.Therefore, turn 3 rotating speed is subjected to the control of four-way cock 9.

On the other hand, adjust screw 12 and exert pressure to damper piston 11, strengthen or reduce pressure in all oil pocket 5-1,6-1,7-1, the 8-1,10, thereby increase or reduce the pressure of all pistons, also can play the turn effect of 3 rotating speed of restriction turning by spring.

As shown in Figure 1 because have on 3 cylindricals of turning gear and with pinion 2 engagement, when as lifting device, hang up weight at rope one end, the other end is hung the object of certain mass, in order to strengthen rope 16 and to turn 3 stiction.Also four-way cock 9 is reached maximum through rocking handle 2-2 rocking-turn pinion 2, adjustment screw 12 is screwed onto the most loose, can promote weight.

As shown in Figure 1, when being used as when rising device, rope one end is fixed on the object of top, the other end is also hung the object of certain mass, and unsettled, and human body is hooked on the hook on the descending lifeline shell, and four-way cock 9 reached maximum, adjustment screw 12 is screwed onto the most loose, through rocking handle 2-2 rocking-turn pinion 2, can promote human body.
