Abstract

The utility model relates to a damping slowly-descending device which comprises a base, a winding roller, a steel wire rope, damping cylinders, a winding wheel, a driving shaft and a crank disc. A first bearing seat and a second bearing seat are respectively arranged at the upper end of the base, the two ends of the winding roller are erected on the first bearing seat, and the two ends of the driving shaft are erected on the second bearing seat; the middle part of the driving shaft is connected with a central shaft hole of the winding wheel, one end of the steel wire rope is wound on the winding roller, and the other end of the steel wire rope is led out from the lower end of the base through the winding wheel; the two ends of the driving shaft stretch out of one end of the second bearing seat and are respectively connected with a central hole of the crank disc; two groups of damping cylinders are respectively located at the two sides of the winding roller, the cylinder body ends of the damping cylinders are respectively articulated with the first bearing seat, and the piston rod ends of the damping cylinders are respectively and eccentrically articulated with the outer side of the end surface of the crank disc. The damping slowly-descending device has the following advantages: the damping slowly-descending device has compact structure and small volume, can descend at a safe speed when the weight is within 30 to 200kg, leads to stable running, is safe and reliable, has more stable speed when loads are changed and leads to low inertia.

Description

The damp slow falling device

Technical field

The utility model relates to a kind of descending lifeline, particularly a kind of damp slow falling devices that can many person-times use repeatedly.

Background technology

Escaping descent control device is primarily aimed at average family and the individual uses, and its structure is made up of speed regulator, safety belt, safety door hook, steel wire rope etc., can carry under the single individual free skating of about 100 kilogram weights at every turn.But this descending lifeline exists two class problems: 1, complex structure, parts are many, make time-consuming, with material more, the cost height; 2, decline process need manually-operated, and can not use continuously, the decrease speed instability, safety coefficient is low; 3, volume is big, be placed in indoorly or outdoor all can occupy the too many useful space, and not attractive in appearance.

Summary of the invention

The purpose of this utility model is exactly the weak point in the background technology, and a kind of damp slow falling device is provided.

For achieving the above object, the utility model adopts following technical scheme: the damp slow falling device, described damp slow falling device comprises base, around roller, steel wire rope, damped cylinder, reel, driving shaft and crank disc, the upper end of described base is respectively equipped with the clutch shaft bearing seat and second bearing block, be erected on the clutch shaft bearing seat around the two ends of roller, the two ends of driving shaft are erected on second bearing block, the driving shaft middle part is connected with the central shaft hole of reel, steel wire rope one end winding is on roller, its other end pile warp reel is drawn from the base lower end, the two ends of driving shaft are stretched out second bearing block, one end and are connected with the centre bore of crank disc respectively, two groups of damped cylinders lay respectively at around the roller both sides, its cylinder body end is hinged with the clutch shaft bearing seat respectively, and tailpiece of the piston rod is eccentric hinged with the end face outside of crank disc respectively in addition.

For a kind of optimization of the present utility model, the oil-in of damped cylinder and oil-out be by the oil pipe intercommunication, and the two ends of oil pipe are connected with choke valve respectively near the oil-in place and near the oil-out place, and the petroleum pipeline that is communicated with fuel tank is communicated with respectively with in the middle part of the oil pipe.

For a kind of optimization of the present utility model, the tailpiece of the piston rod of described two groups of damped cylinders is connected with the end face of crank disc is eccentric respectively, and its phase place difference angle is 90 degree.

For a kind of optimization of the present utility model, described steel wire rope is walked around a circle at reel at least.

For a kind of optimization of the present utility model, a described wherein end outside roller stretches out the clutch shaft bearing seat is connected with the main shaft of motor.

The utility model is compared with background technology, has compact overall structure, and volume is small and exquisite, can descend with safety speed between 30Kg--200Kg at weight range, operates steadily, and safe and reliable, speed is more stable during load variations, and inertia is little.
