Abstract
The utility model discloses an adjustable constant-speed lifesaving descent control device, comprising a base plate, a planet wheel mechanism, a friction block, a friction ring, a speed regulation device and an end cap. Planet wheels are connected with rope wheels fixedly; the right side of a central wheel is fixedly connected with a friction box provided with the friction block; and the central wheel rotates at a higher speed through planet wheel acceleration and drives the friction box to rotate at a higher speed and to generate a centrifugal force which enables the friction block and the friction ring to form a damping friction pair. The adjustable constant-speed lifesaving descent control device is characterized by comprising the pre-tightening speed regulation device and being capable of pre-tightening lower end rolling wheels through the pre-tightening device fixed to a pedestal for improving friction and realizing adjustability and stability of speed. The descent control device has the advantages of stable descent speed, adjustability, safety, reliability, small volume, and lightness, and allows the speed to be adjusted properly according to different users.
Description
Technical field
The utility model is to the improvement of existing lifesaving descent control device, provides a kind of adjustable, and lifesaving descent control device at the uniform velocity belongs to the high-level lifesaving device technical field.
Background technology
Current, along with the quickening of urban construction paces, urban land day is becoming tight; Force the mankind to the high-altitude development, high-rise building is more and more, and high-rise ratio is increasing but Along with people's is lived; In case uncertain emergency takes place such as fire; Earthquake and so on, traditional fire fighter's safety apparatus such as escape devices such as aerial ladder, air cushion can't make high residential building, and the people of office building are withdrawing of safety rapidly.Occurred at present quickening the escaping descent control device slow down through friction pair then through the gear one-level.Existing descending lifeline does not all have well to solve the problem that slip takes place for steel wire rope and reel, has increased unsafe hidden danger.
Summary of the invention
The utility model provides a kind of can pretension to be regulated, lifesaving descent control device at the uniform velocity, and purpose aims to provide a kind of more safe and reliable, and is easy to use, velocity-stabilization, and can be at lifesaving device for building tool safety, that regulate in the small range.
For achieving the above object, the solution of the utility model is: be made up of steel wire rope, base plate, reel, separated time wheel, planetary wheeling mechanism, brake pad, drag ring, speed governing pre-tightening apparatus and end cap.Wherein the pretension wheel in reel, separated time wheel and the speed governing pre-tightening apparatus all has the winding slot of V-arrangement, and the groove inwall all has decorative pattern to play anti-skidding effect simultaneously to increase friction.The utility model adopts the planetary gear transmission, and planetary gear quantity is 3.The spring pretension arrangements for speed regulation of original creation have been increased simultaneously on this basis.Pretension wheel in the spring pretension arrangements for speed regulation is two, is symmetrically distributed in nethermost separated time wheel both sides.Knob in the spring pretension arrangements for speed regulation can rotate, and knob can promote spring, through spring compression pretension wheel, increases frictional force between the two thereby the pretension wheel can compress steel wire rope again, realizes the rotating speed adjustable of descending lifeline, can also play the effect of stabilized speed.
The utlity model has following advantage is: one of which, and the stainless steel structure of descending lifeline, volume is little, and is in light weight, durable.Its two, the deceleration effect stability does not damage steel wire rope, can repeatedly use.Its three, exclusive pretension arrangements for speed regulation can make this descending lifeline more safe and reliable.

Fig. 2 is the internal rows star-wheel vertical view of the utility model.
Fig. 3 is the sketch map of pre-tightening apparatus.
Fig. 4 is the structural representation of friction box.
The specific embodiment
Below in conjunction with accompanying drawing the structure and the principle of the utility model are done further explanation.As shown in Figure 1,1 is base plate, and 2 is reel, and 3 is planetary gear, and 4 is ring gear, and 5 is centre wheel; 6 is end cap, and 7 is friction box, and 8 is brake pad, and 9 is fabric wheel, and 10 are the nut of screwing; 11 is preloading spring, 12 pretension push rods, and 13 pretensions wheel, 14 are the separated time wheel, 15 is steel wire rope.Steel wire rope is upwards walked around reel through one through the pretension wheel and the V-shaped groove of fabric wheel, and V-shaped groove stretches out this descending lifeline between fabric wheel through opposite side and the pretension wheel then.Concrete operation logic does, when steel wire rope is descended with personnel by the gravity effect of human body, can drive reel 2 and rotate together; Reel 2 drives with its three planetary gears (as 3) that connect firmly when rotating and rotates, and planetary gear 3 and 4 engagements are simultaneously with 5 engagements; Three planetary gears drive centre wheel 5 and rotate; Centre wheel 5 rotations can drive with its friction box that connects firmly 7 and rotate, and brake pad 8 that can be radially movable in it when friction box 7 high speed rotating contacts the generation frictional damping with end cap 6 inner drag ring 7 parts; This frictional damping is directly proportional with rotating speed, so can play the effect of deceleration.
Simultaneously in concrete the application because individual difference, for its safer landing, can pretension be taken turns pretension for the elderly and children through rotating 10; Concrete principle is for passing through rotation knob 10, and spring will promote the pretension push rod, thereby the pretension wheel can contact with the separated time wheel more closely; Thereby increased the resistance that steel wire rope passes through; Screw before use to increase the pretightning force to steel wire rope, increase frictional force, both can having prevented skids also plays the effect that speed stabilizing is slowed down.
When using, connect with fixing chain or the enough fixtures of intensity with the base plate of link with this descending lifeline; With an end of holding tight steel wire rope; Then devices such as safety belt are hung over an end of steel wire rope, can grasp steel wire rope thereafter, climb out of outside window; Descending lifeline can slowly descend under the effect of body weight for humans power, thereby in contingency, successfully escapes.
