Abstract
The utility model relates to a self-saving safety rope for lowering a person from buildings. A rope wheel is installed in an outer shell which is composed of a fixing cover shell and a movable cover plate. A friction sheet is installed on the movable cover plate. A convex wheel arm controls braking force of the friction sheet to the rope wheel. So lowering speed can be controlled. The purpose of safe self-saving can be realized. Because the limitation degree of the rope wheel and the load of the rope wheel are in direct proportion, the risk of falling which is caused by false operation can be avoided. Thus, the utility model has the characteristics of safety, easy mastery, compact structure, small size, convenient storage, convenient placement, portability and convenient operation.
Description
The utility model relates to a kind of safety rope, during particularly prominent aloft running into dangerous situation, can hightail a kind of utensil of saving oneself of dangerous situation.
General safety rope is under the border, field that may fall dangerous, and bundle hangs over the party on one's body in case a kind of precautionary measures that falling stop falls in advance, and this class safety rope has only when carrying out and a certainly just uses when the special activity of falling dangerous is arranged.But, when people in the skyscraper or on the high layer building or other eminence meet sudden dangerous situation, need or withdraw downwards rapidly by rapid landing, during the threat that could break away from, save oneself with regard to being difficult to use general safety rope.
The purpose of this utility model be will for people provide a kind of and live aloft, work or other when movable, a kind of eminence that the breaks away from sudden calamity safety rope of saving oneself.
The shell that the purpose of this utility model is achieved in that this device is connected to form through hinge by fixedly case and movable cover plate, and fixedly the steel cable exit on the case is equipped with guide wheel.Twine the rope sheave of steel cable, be difficult to rotate by the contact of the friction plate on the movable cover plate, when steel cable and manned steel cable carry out work and are stressed, the horizontal component that the human body body weight forms makes friction plate compress rope sheave, rope sheave then can't rotate or can't quick rotation, it compresses degree and is directly proportional with the human body body weight again, thereby regardless of evacuee's body weight, the state that can only be in vacant state or slowly fall, when needs fall or comparatively fast fall, the evacuee can regulate the rotating speed of rope sheave by raising handle, makes it to break away from the calamity of being met safety quickly, realizes the purpose of saving oneself.
Because adopt such scheme, rope sheave is in on-position all the time, is difficult to take place misoperation during use, and can regulate decrease speed easily again, thereby has good security and operability.
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a vertical section structure schematic diagram of the present utility model.
Among the figure: 1. the fixing case 4. movable cover plate 5. friction plates 6. hinges 7. stop bolts 8. cam arms 9. rope sling pins 10. handles 11. manned steel cable 12. steel cable guide wheels 13. wheel shafts 14. times rope handle of rope sheave 2 steel cables 3.
Steel cable hook and manned rope sling do not omit to be drawn.
In the drawings, fixedly case (3) is connected with rope sheave (1) by wheel shaft (13), and links to each other with movable cover plate (4) by hinge (6), the one side of movable cover plate (4) and friction plate (5) riveted joint, the lower half circle of friction plate (5) contact rope sheave; The movable cover plate (4) of two correspondences connects in the bottom by stop bolt (7), and the two ends of stop bolt (7) connect cam arm (8), and manned steel cable (11) is connected on the rope sling pin (9) on the cam arm (8), and the lower end of cam arm (8) is equipped with handle (10).Because the effect of friction plate (5), rope sheave (1) is in on-position all the time, and after manned load-bearing, effect by cam arm (8), friction plate (5) further compresses rope sheave (1), when on when raising one's hand handle (10), friction plate reduces the pressure of rope sheave, because of the effect of manned body weight makes the rope sheave rotation by force.By regulating the pressure of friction plate to rope sheave, can obtain different decrease speeds, under the effect of steel cable guide wheel (12), reduced the wearing and tearing of steel cable, avoided the fixedly deflection of case (3).When returning rope, backward rotation is returned rope handle (14) and is got final product.
Claims (4)
1, a kind of eminence safety rope of saving oneself, mainly by steel cable, rope sheave, fixedly case, movable cover plate, friction plate, hinge, cam arm, manned steel cable are formed, it is characterized in that: fixedly case and movable cover plate connect to form the shell of rope sheave by hinge, its movable cover plate connects friction plate, rope sheave is installed among the shell, and friction plate is near rope sheave.
2, the eminence according to claim 1 safety rope of saving oneself, it is characterized in that: two movable cover plates are tied by stop and connect, and stop bolt two ends connect the cam arm.
