Background technology
No matter be that flexible tension member flat, circle or other shape is in order effectively all to have required the termination.Be applied in the various tension member in the technical field that needs tension member, each has all used the different termination of many kinds.On the tension member of circular cross section, knit out cringle, or with other material cringle, tension member passes this cringle; In tension member, often use ring to form cringle; In tension member, also use u shape bolt and other compressing member that has dish to form cringle; Also can use bonding material that tension member is installed in the anchor clamps of termination.Particularly for elevator technology, in the termination of each prior art of Tao Luning, distributes tension is most important equably between the load-carrying unit of tension member in the above.By guaranteeing balancing tension between load-carrying unit, can provide maximum yield strength.In other words, when all load-carrying units of tension member are kept in balance the situation of tension force, can obtain maximum disruption characteristic, because will make the tension member fracture, the inevitable fracture simultaneously of all elements.When the load-carrying unit tension force of tension member is unequal, some over-tension in the load-carrying unit and other tensioning deficiencies.The consequence of this situation is that total disruption characteristic of rope reduces, and only is placed on the part load-carrying unit in this load, has exceeded the yield strength of these elements.Possible performance reduction causes such situation: the tension force rank of member is lower than its rated tension.Therefore, especially in elevator technology, tension member generally terminates on the load-carrying unit with the basic load that equates.Because the system of most of use tension member is design-calculated for economic aim, so the maximum yield strength of member does not wish to have any significant reduction.Only be that for a specific system, unbalanced stressed comparing with producing balanced forces needs the tension member that intensity is higher, expense is more expensive owing to discontinuity equalization.So, wish to make very much a kind of termination, all load-carrying units that make specific tension member are the phase equivalent-load all.
Except the carrying design that forms an equiblibrium mass distribution, the more important thing is that the load member that will guarantee tension member can not slide over each other or slide together with respect to attaching parts in the end, do not wish to produce this two kinds of results.The distribution of load can realize with methods such as compression, adhesives and braidings in circle rope (normally steel cable).Regrettably, realize that the existing method of this termination is not suitable for the flexible flat rope of small bore strand and poly-mer crust.Particularly for the epoxy termination of prior art, steel cable will spend shape to insert (berosetted), and choosing examination repeatedly is adhered in the socket with epoxy again.Because this gauge of wire, this method is very effective.In the very little flat ropes of strand diameter, flower shape socket is not really effective.So be starved of a kind of termination technology.
Summary of the invention
Connecting device and the method for the shortcoming of above-mentioned prior art by epoxy sealing of the present invention overcome or alleviated.
In the present invention, by epoxy (or other material) adhering method being used to have the flexible flat tension member of a plurality of carrying strands, overcome above-mentioned shortcoming of the prior art.This method adopts an insert, is used for single strand is arranged in predetermined regular shape, and strand receiving channel and special geometric form are provided, and increases the confining force that tension member is fixed to the binding resin on the termination.One socket is provided, and after the single strand tension (or tightening) of insert and tension member, this socket is admitted insert.Then a kind of bonding material, epoxy preferably, be applied in the receiving opening on the socket, so that insert and all strands, insert and socket are permanently linked together, strand is fixed to a such state: the power that is applied on each bar strand equates basically.
A first aspect of the present invention provides a kind of flexible flat tension member end device, and it comprises: a socket; One has the insert of groove in top and bottom, described groove be dimensioned in a plurality of strands of admitting the tension member for the treatment of termination one; One leakproofing material that described a plurality of strands, described insert and socket are linked together.

Fig. 2 is the block diagram of insert of the present invention, so that understand its geometric configuration and the regularly arranged form of receiving channel.
The specific embodiment
At first, should be noted that end device of the present invention relates generally to a kind of flexible flat tension member, it is disclosed in the United States serial NO.09/031 of application on February 26th, 1998, in 108, exercise question is " a kind of tension member of elevator ", and the trust of on October 22nd, 1998 application number for NO.98-2143, be entitled as the subsequent application of " tension member of elevator ", at this with both's document incorporated by reference.
Referring now to Fig. 1,, illustrated the present invention with the termination form, flat tension member 10 terminates on the socket termination 12.
At first insert ends of tension members 10 in the socket 12 because at the strand of tension member with after insert 30 engages, socket 12 must be near the end of tension member 10.
Socket 12 comprises a U-shaped end 14, is used for pivotally admitting by general device 18 being connected to connector 16 on the lift car (not shown).U-shaped end 14 has bearing pin 20 and steady arm 22, and bearing pin is used for reducing the flexure stress of tension member 10 ends, and this member contacts with connecting device 24 at this.
Referring to Fig. 2, illustrated insert 30 of the present invention in the block diagram.Those skilled in the art will find around the geometric configuration of insert 30 many through holes 32 are arranged.As known purpose in the prior art, the effect in these holes 32 is to make epoxy or other leakproofing material to flow through, and guarantees to seal insert 30 fully, thereby seals the termination of tension member 10 fully.Is curved 34 at insert 30 away from an end of tension member 10 with at the top of Fig. 2.Arise from the inside face 36 of insert 30 for curved 34, and with about 90 degree of about 5 millimeters radius bend.This radius can be selected this radius in 2 millimeters and 25 millimeters scopes, help crooked 180 degree of single rope of tension member 10 and can not tangle.And the formed surf zone of this radius increased the friction on each strand of tension member 10, thereby increased the confining force of termination.Along curved 34 outer rim is many grooves 38, is spaced apart from each other, and forms the regularly arranged of groove.The quantity of the groove that is provided equals the number of strand in the flat tension member 10.
The size of each groove 38 is preferably made slight clamping admittance strand within it.This is in order to keep strand tensioning slightly when adhesive agent or epoxy flow into end device.By strand being remained on tensioning state slightly, just more can guarantee the tension force basic equalization on each strand.
Pass the line of centers of insert 30 and by behind each groove 38, spur strand (as shown in the figure) downwards and make it more near the body 42 of insert 30.Strand is tightened (element 40 can be clip or other device that grasps the strand end) in the groove 40 by the corresponding groove on insert 10 near-ends (bottom among Fig. 2).Strand preferably passes groove 40, and its free end is put into the hollow space of insert 30.Clever technical personnel in the termination field will be appreciated that curved 34 and not only provides and makes the radius that strand smoothly passes through but also the strand and the body 42 of insert 30 are separated.Strand by after the groove 38 up to by before the groove 40, the body 42 of contact insert 30 not.Strand separates with body 42 like this, helps to seal each strand fully with epoxy material.
Be appreciated that insert makes each strand also cause the bending of two 180 degree effectively effectively, has increased the friction of strand on insert widely, and has increased effective shearing strength value of the termination that has applied epoxy.This design guarantees that each strand can not pull from epoxy, and provides the failure-free termination for flat tension member 10.
" end 44 " that is to be further noted that insert 30, is preferably oval-shaped.This ellipse is consistent with the flat configuration of flat tension member, thereby is more suitable for admitting the strand of this tension member.
In use, about 6.3 inches of tension member 10 termination strip ofves, but should be noted that this length is at the tension member of 30 mm wides, should adjust according to the different in width of element.Usually, along with the tension member width strengthens, the strand of strip off is longer.The free strand that exposes after rubber on the flat tension member 10 peeled off penetrates insert 30 from bottom shown in Figure 2 44, and is concordant substantially with the bottom 44 of insert 30 up to the not strip off part of tension member 10.The length that each strand is peeled off will be enough to pass insert 30 so that sub-thread tightens in the groove 38, leave insert 30 the outside face sub-thread pull down and tighten in groove 40.Then the free end of strand is placed in the insert 30.
After insert 30 correct wirings, socket 12 engages with insert 30, and with epoxy or other suitable bonding material insert 30 and socket 12 is permanently fixed together.By like this, for good and all permanent wiring insert 30 and socket 12, tension member 10 for good and all connects in a kind of failure-free mode.
In supplementary features of the present invention, provide groove 46 (Fig. 2) with adjustment insert 30 and socket 12.These characteristics help to align insert in socket, to keep the in the right direction of tension member.When adopting this feature, the bump bonds on groove 46 and the socket 12 is so that align.
