Abstract
Make a people or the device that weight lands with a rope, it can automatically stop people and weight to continue motion again; It can be applicable to the rope of different-diameter simultaneously.The device of this invention comprises that is installed in the friction cylinder on the substrate, the control lever of a friction piece and a pivotally.The end of control lever is provided with two opposed cam surfaces, no matter the direction of motion of rope how, cam surface on the control lever and the friction between the rope, make rope by drift ping between this cam surface and friction piece spill braking surface.When with hand control lever being put into position intermediate, two cam surfaces and spill braking surface gap increase, and rope can allow freely-movable.
Description
The present invention generally speaking is about make the device of a people or a weight landing with a rope, particularly about there being one to be installed in a friction cylinder on the substrate, a friction piece and a pivoted control lever, rope is at least on the circumference of pile warp friction cylinder and a friction piece part therein, and by between the surface and control lever of friction piece.When rope slips over,, device is braked automatically to rope thereby control lever is rotated owing to contact with a cam surface friction of control lever.
The u.s. patent application serial number the 296374th that the pattern that rope of a kind of usefulness makes a personal descent apparatus was submitted to as on August 26th, 1981, it is equivalent to the publication No. 0046891A3 that european patent application 81106095.3(1982 published at March 10).The enforcement case of this device is shown in Fig. 7 in the specification～10, and rope is pile warp friction cylinder one circle half at first, then through an additional friction piece.In rope conversion in licking journey about 180 ° of direction.So the flat braking surface of rope on the additional friction body, and through a control lever cam surface that rope is applied bias voltage with spring.When rope slided between braking surface and control lever, often the cam to control lever produced certain friction.If control lever can freely rotate,, make control lever energy wedging rope between braking surface and control lever, thereby device is stagnated on rope so rope just has the tendency of rotation control rod.Be intended to make rope to continue can not stop rope toward downslide as a people, braking just can not take place yet.
A shortcoming of aforementioned means at first is exactly that this spring is absolutely necessary to the performance that guarantees this device.And spring is a weak link, because it needs the regular performance checking that carries out, and for confirmation whether fractureing or living the embroidery; And after this device uses, be placed a period need not, this root spring can not lose performance because of other any reasons.We can say the ability that can this whole device the maintenance effect, crucially just be whether the performance of this spring is normal.
Embodiment Fig. 1～7(in the aforementioned application consults former specification), make the additional friction body of rope pile warp make eccentric rotary for avoiding this shortcoming.Like this when rope moves, the additional friction body just rotate and the wedging rope between braking surface and it, thereby stop rope not continue to move.In any case but this device shown in Fig. 1～7 is too heavy and too expensive.And the use under bad environment of this device also is easy to lose efficacy.Must offset the brake force of additional friction body because wish from control lever to the additional friction body through gear transmission with land the there power that needs of rope.The gear drive corrosion just might jeopardize performance, needs the less precision machined part of some tolerances simultaneously again.
The existing device that the people is landed with rope is not gratifying so simple.The requirement of all relevant safety operatings that proposed below in addition, existing device also can not satisfy.
A, device should be able to use the rope of different-diameter in certain limit, especially should be able to allow especially to use since absorb water make vary in diameter rope;
B, should avoid using spring and gear etc. easily to cause the machine components that lost efficacy;
C, control lever comprise that the eccentric required area of installing of braking should be easy to exchange, thereby install and can use multiple different rope, or than (a) described rope that bigger different-diameter is arranged like that;
D, control rate accurately;
E, take place to produce braking action after incorrect packing into when rope is accidental.For example when rope motion through the direction of control lever and desirable direction not simultaneously;
F, when using this device reaction incorrect, people should produce braking action; (that is to say that he or she pushes away or draws control lever to braking rather than loosening);
G, device should be able to apply to different modes, that is to say, can also can pin on certain position with this device with the rope landing.
The rope that utilizes that the purpose of this invention is to provide a similar above-mentioned pattern makes the device of a people or a weight landing, and meets every requirement recited above.This strict demand to safety in operation and constructional simplicity all is very important.The present invention has used an additional friction body for reaching these purposes, and it is provided with the spill braking surface of extension along the surface of the rope direction of motion; Simultaneously be provided with a control lever facing to this spill braking surface, its end has two cam surfaces.Like this, at this moment not to loosen but braking action takes place when control lever is pulled to or is pulled to the opposite way round unexpectedly.Even also braking action can take place when using difform rope.Because when rope when any one direction is slided, will produce braking action automatically through the cam surface of control lever.And the control lever that has cam surface is very easily changed, and is installed in the there because it is a simple part with simple method.During the much bigger rope of diameter, control lever just should change replacing if pack into.Even but control lever is not when changing, this device will have only with the little rope of vary in diameter works.Because rope often is to be stretched along the spill braking surface of friction piece like this, its will necessarily contact generation wedging effect and Braking mode with a cam surface of control lever.
Purpose of the present invention, advantage and characteristic just can clearlyer be come to understand from following detailed explanation and accompanying drawing.
Fig. 1 is one embodiment of the present of invention front views, the situation of expression enclosure;
Fig. 2 is according to the II among Fig. 1-resulting profile of II line.
Fig. 3 is the bottom view according to direction of arrow indication among Fig. 1.
Fig. 4 is that schematic side elevational Fig. 1 of Fig. 1 embodiment represents alternative mode of operation;
Fig. 5 is the operational circumstances that a diagrammatic representation is represented apparatus of the present invention.
Consulting drawing now, mainly is to consult drawing 1, and it has illustrated the device that makes a people or a weight landing with a rope.Device in Fig. 1 comprises the shell of being made up of substrate 2 and bead portion 31.The inner case of shell as shown in fig. 1, covering 4 in the drawings is to be in the position of opening.Lid 4 is to be contained on the shell with hinge, and lid turns right and just can close as can be seen from Figure 1.It has been screwed in the threaded bore 6 and cover lock can have been lived (see figure 3) to tighten the circular knob of annular knurl 5.
The concave surface 15 of friction piece is positioned in the right opposite of the control lever 19 that can use handle 20 operations.Control lever 19 is installed in rotation on the trunnion bearing 21, is provided with two cam surfaces 22 and 23 in its end, just in the face of spill braking surface 15.Because cam surface 22 and 23 is in the termination of control lever 19, thus each cam surface 22 and 23 to the distance at trunnion bearing 21 centers of rotation just greater than being close to each face on the control lever to the distance between trunnion bearing 21 centers.Cam surface 22 and 23 shapes are decisions like this, and when control lever 19 according to circumstances rotates up or down, corresponding cam surface 22 and 23 will be shifted to concave panel 15 to reduce the distance between respective cam surfaces and the concave panel.In general cam surface 22 and 23 is arranged on gantry post 21 opposed both sides.Between these two cam surfaces of control lever, just need the another one face like this, make this other face to the distance at trunnion bearing 21 centers less than these two cam surfaces 22 and 23 respectively to the distance at trunnion bearing 21 centers.
In Fig. 1, rope 16 is to be placed in by this way in the shell 1, promptly hangs on the fixed pivot as shown in Figure 5 when the upper end of rope 16, just can utilize rope to land.Plan to hang in the perforate 8 of substrate with the safe fastener of people's belt up 17 usefulness of rope landing.Rope 16 passes perforate 11 from below and enters in the shell, crosses friction piece 13 then.Rope 16 is at first crossed spill braking surface 15, and pile warp convex 14 makes the rope direction change about 180 ° then.Cable loop approximately through 270 ° (promptly 3/4ths of a circle), is just upwards guided enclosure into through perforate 9 around friction cylinder 12 then.
Rope is to move on two planes.As shown in Figure 2, the inwall of substrate 2 tilts, thus the track of rope with from the perpendicular direction in the plane of Fig. 1, moved the amount of movement that approximates the rope diameter size to the side.From A point topmost, rope has changed direction and has walked around friction piece 13 down to bottom B point, and rope is walked around the bottom of friction cylinder there.
Control lever has two operating positions can utilize as shown in Fig. 1 and Fig. 5.When first operative position, utilize the people of rope landing control lever 19 can be loosened.Hang over the people in the perforate 8 on the device with belt 17 and fastener 18 so, just can draw this device downwards with his body weight.As a result, just there is a trend that rope is upwards drawn through perforate 9.Rope also moves through perforate 11 simultaneously from bottom to top, and it at first passes through between the spill braking surface of cam surface 22 and friction piece 13.When this point,, as shown in Figure 1, thereby the distance between cam surface 22 and the spill braking surface 15 is reduced because the friction of rope and cam surface 22 makes rope closely contact with cam surface 22 cam surface is moved in the direction of the clock.When control lever 19 forwards as shown in Figure 1 position to, make rope 16 tightly wedging between cam surface 22 and concave panel 15.Therefore this device does not need to use the control lever just can be under stop on the rope.
When second operative position, utilize the people of rope landing that control lever 19 is upwards rotated, to a position that approximately parallels with chain-dotted line L among Fig. 1.At this moment, the distance on the concave panel 15 of friction piece and control lever 19 surfaces can make rope 16 through between friction pieces and the control lever and can be by wedging.Rope changes direction through the A point, passes through the convex 14 of friction piece 13 again.Rope turns around through friction cylinder 12 with 3/4ths then, upwards guides the outside of shell 1 into through perforate 9 at last.Are the braking actions that can be subjected to part when rope motion pile warp friction piece 13 and friction cylinder 12, but can not stop fully.
Cam surface 22 and concave panel 15 must match each other, and the body weight according to the people who uses this device is configured simultaneously.When control lever 19 was placed on the L position, people's body weight enough can make rope can just pass through this device to give fixed initial velocity greatly.When control lever 19 was placed on the L position, cam surface 22 and braking surface 15 must the location, produces enough braking actions, made the rope can be tranquil and sure ground, speed pass through this device not too greatly and stably.Therefore, control lever 19 should have enough big adjusting space, makes its can counter-clockwise direction rotate so that governing speed accurately.
Fig. 4 is an alternative embodiment of the invention, puts into rope therein, and utilizes safe fastener 25 that this device is hung on some fixing points through perforate 7.
In Fig. 4, rope 16 earlier after down again from passing this device, and the directed outward of coming out from the bottom of device.In the embodiment of Fig. 4, rope can move to both direction.As an example in Fig. 4 embodiment, rope enters from the bottom from perforate 10, around a circle half, at first walks around the convex 14 of friction piece 13 to friction cylinder 12 then, downwards through perforate 11 from installing interior directed outward.Like this,, the distance of 15 of the convexs of cam surface 23 and friction piece 13 is reduced because 23 CONTACT WITH FRICTION of cam surface of rope and control lever 19 make control lever do the counter-clockwise direction rotation as shown in Figure 4, thereby rope wedging tightly.
Arrangement have two cam surfaces 22 and 23 control lever 19 over against the spill braking surface to allow with different modes with in the rope charging apparatus.In each case or when both direction moves, rope can utilize one of two cam surfaces cam surface tightly wedging effect and automatically brake.And when with hand control lever being turned to the L position, rope can move once more.
This device can use the rope of different-diameter.Because friction piece 13 has a concave panel 15 to face cam surface 22 and 23, and rope is often to be in extended state in this zone, it can be pressed on the cam surface in two cam surfaces 22 and 23, make rope come rotation control rod 19, thereby the rope wedging is produced braking action automatically by friction.
