Abstract

The invention relates to a grooved pulley sliding cable device. A hanging and dropping cable can be embedded when an upper and a lower rocker arms extend (are separated), and the ends of the rocker arms are provided with guide pulleys; when the upper and the lower rocker arms hold the grooved pulley, the dropping cable is led to be wound in the circumferential groove of the grooved pulley; and a large circumference wrap angle holding friction force of the cable wound in the circumferential groove is utilized. Meanwhile, the gliding speed can be controlled by the grooved pulley sliding cable device tied in front of a chest of person through the brake control of a brake disc which is coaxially fastened with the grooved pulley, so that the person can safely slide to the ground from a balcony or a window.

Description

Grooved pulley sliding cable device

Technical field

The invention belongs to mould manufacturing, mechanical field.

Background technology

In order to save soil and social develop rapidly, live in high building office or human settlements, learn to get over generally, just in case earthquake or fire, in order to keep away calamity fast, select balcony to hang a rope sometimes and slide into ground fast with the slip rope device, leave the dangerous place of the condition of a disaster, also be the road of many escapes, many passages of seeking survival.

Summary of the invention

Goal of the invention: 1. give the people who works, lives, learns upstairs, when disasters such as earthquake, fire, war, terrorist incident face, provide one to keep away the calamity passage more to keeping away the calamity personnel; 2. everyone is equipped with a grooved pulley sliding cable device of the present invention separately at ordinary times for for example young workman, young student, and enterprises and institutions are equipped with every room high-strength complex condensating fiber rope (not only light but also strong) of unified standard; Passage in a planned way carries out at ordinary times as fitness training and keep away the calamity manoeuvre, just in case can not pass through the time, just can be selected slip rope.

Technical scheme: Fig. 1 is the front elevation of grooved pulley sliding cable device, and the end user stands in the behind of slip rope device, also facing to us; It is the front that grooved pulley sliding cable device ties up to the end user.On climb A and connect shoulder belt, climb the left thigh endless belt that B connects the end user down, C climbs with D and climbs that (D climbs on base 10, and at voussoir 22, the back of guide rail 21 be cannot see) is that abdominal belt is climbed, (all shoulder belts, abdominal belt etc. are all drawn).It is that arch to our direction is protruded is climbed that E climbs, if end user's the right hand is held C and is climbed, left hand catches E to climb, as drawing chest expander, the outside pulls to the left and right, then E climbs and drives voussoir 22 and extract, break away between upper and lower two rocker head 1a, make spring 22b compression simultaneously, bump against on the 21a that inserts up to recess line 22a, promoting guide rail 21 moves to (being our right direction) to end user's left-hand, with guide rail 21 fixedly all-in-one-piece bow body 20 drive each connecting plate 3 up and down, each is above, lower shaft 2 reaches the double dot dash line position for pivot outwards shakes to make upper and lower two rocking arms 1; Just become the shape of Fig. 2.The two rocker head 1a up and down of this moment are blocked by ramp blocks 11, just make guide rail 21 be pulled out to extreme position.Decontrol now hand E and climb, E climb with voussoir 22 return under the elastic force of wedge spring 22b blocked by the interlude of bow body 20 till.(connecting plate draws) spring 6 of this moment has been crossed the up and down axle 2 of two rocking arms, institute so that up and down two rocking arms remain on open extreme position.

Fig. 2 has removed lid 30, all disappears so climb or the like at brake disc, the C of lid on 30.A climbs, B climbs greatly especially, and they also have and the people isolates and safety effect, when last lower tumbler 8, play buffer action when going up lower shake-changing arm 1 swing and between the end user.

The common tangent (double dot dash line) of the last lower tumbler 8 of Fig. 2, and the tangent line of sheave 12 (short double dot dash line) between distance X, when being to use the application's grooved pulley sliding cable device, the scope that allows the vertical rope that hangs (Fig. 1 14) embed.

Fig. 3 is the fragmentary top pseudosection of ramp blocks 11 and sheave 12.Rope 14 (sectional drawing) is run into ramp blocks 11, is easy to be imported in the groove of sheave 12 along arrow by the inclined-plane.

Fig. 4 is the partial perspective view of base 10, guide rail 21, voussoir 22.2a is the mount pad of rocker arm shaft 2 among the figure, and 10a is a guide groove, is the molding high-strength engineering plastic spare with base 10 integral body, is to be slidingly matched for guide rail 21.The 22nd, voussoir, the voussoir bottom surface is a little more than the face of base 10.22c is the seat hole of wedge spring 22b.21 of low order end is sections of guide rail; Insert 21a and handle 21b also will be installed in the extension position of guide rail.

The guide groove 10a of Fig. 4 (cross section is inversion T font) runs through whole base 10, and except that strengthening rigidity, also the axle 13 for sheave 12 is provided with the required thickness of bearing block; In the bearing block periphery, again at molded sky.

The guide rail 21 of Fig. 1 is the states that finish that are among the retraction base 10, so the bow body 20 that solid line is represented has been run into base 10, bow body 20 is connected with rocking arm 1 with connecting plate 3, connecting plate 3 usefulness bearing pins 5 by bearing pin 4, impels guide wheel 8 14 pressures of keeping vegetarian to wrap in the groove of more than half circumference of sheave 12.(the connecting plate elongated end is a bit inclined to one side to our people's one lateral bending in the stake 7 of connecting plate elongated end because spring 6 hangs over, it is unsettled that spring 6 is in), so when guide rail 21 is gone back a retraction one half, two 7 line (being the line of pull of spring 6) is just crossed the line (supposing line) of two rocker arm shafts 2 up and down up and down, so two rocking arms 1 were filled the span of a man's arms suddenly outside sheave 12 about the pulling force of spring 6 (pulling force is in maximum constantly) impelled, voussoir 22 is just brought into by guide rail 21 passively, effect by wedge spring 22b, make voussoir 22 insert up and down between two rocker head 1a the position of lower tumbler 8 in the locking.

Fig. 1, four pieces of screw rods of base 10 and lid 30 usefulness, nut 31 are fastening; The axle 13 of sheave 12 also has a bearing in lid, lid 30 is just with four pieces of screw pairs and axle 13 bearing guard settling position, and (we the people) right side of lid and the excircle of sheave 12 are about the same greatly.

At the lid bearing outside, axle 13 extended spots (promptly covering outside 30) brake disc 32 is housed, brake ribbon 33, spring 34, trying hard to keep of spring 34 held the brake ribbon banding, embraced brake disc 32, promptly is: make sheave 12 locked at ordinary times.When the people's who uses the slip rope device weight is added on the slip rope device, still can not glide, have only when the end user be sure of ready can the downslide, down by subtracting brake lever 37, by bearing pin 37a, make tappet 35 compression springs 34, make brake ribbon reduce the degree of cohesive force, control end user's decrease speed.Stake 36 is fixing points of brake ribbon.

This programme is more several application patents of invention than in the past: without worm couple, and main parts size is molded with high-strength engineering plastic, and the efficient height is in light weight during batch process, and is simple in structure.
