As shown in Figure 1, sleeve 5 has big opening portion 52 that inserts for wedge-like member 2 and the little opening portion 53 of drawing hoist cable 1 usefulness.
As the formation method of hoist cable 1, as shown in Figure 4, metal filament 11 is carried out twisted and forms strand 12, and further strand 12 to be carried out twisted and forms bundled steel wires be twisted thigh bundle (schenkel) 13, afterwards the twisted thigh is restrainted 13 twisteds and become hoist cable 1.Core twisted thigh bundle 14 is set at the center of hoist cable 1, around it, with the interval that equates a plurality of sidepiece twisted thigh bundles 15 is set along the circumferential of hoist cable.Be filled with the inner layer resin 16 that for example is made of polyurethane between sidepiece twisted thigh bundle 15 and core twisted thigh bundle 14, under normal conditions, bundled steel wires is that twisted thigh bundle can not come in contact each other.In addition, around sidepiece twisted thigh bundle 13, be provided with the outermost resin 17 that for example constitutes by polyurethane.Twisted thigh bundle 13 is covered by outermost resin 17, thereby has avoided coming in contact with other twisted thigh bundle and rope sheave under the protection of resin.
Below the permanent order of the hoist cable of the hoist cable end anchor fitting that adopts present embodiment is described.
When the hoist cable end anchor fitting with present embodiment is connected with hoist cable 1, at first controls member 3 and clamp hoist cable 1, and fix with screw 31 and to control member 3 with two.Then, make elastic component 4 deflections, and it is installed in controls on the member 3, after this wedge-like member 2 is pushed towards elastic component 4, and clamped hoist cable 1 with wedge-like member 2 with the addendum modification of regulation.Afterwards, with hoist cable 1, wedge-like member 2, control member 3 and elastic component 4 inserts in the sleeve 5 together, pull out hoist cable 1 from little opening portion 53.When pulling out hoist cable 1, hoist cable 1 and control member 3 and move towards little opening portion 53 from sleeve inner.At this moment, elastic component 4 is by wedge-like member 2 and control member 3 compressions, and elastic component 4 makes wedge-like member 2 move towards the direction of little opening portion 53.Along with wedge-like member 2 moves towards little opening portion 53 along wedge-like bearing surface 51, hoist cable 1 is clamped by wedge-like member 2.When the friction force between wedge-like member 2 and the hoist cable 1 becomes greater than the friction force between wedge-like member 2 and the wedge-like bearing surface 51, wedge-like member 2 moves towards little opening portion 53 with hoist cable 1 simultaneously, when the bounce that causes in the compression by hoist cable 1 and the pressing force balance of wedge-like member 2, wedge-like member 2 stops to move.
Below the hoist cable end anchor fitting of the present embodiment when lax is taken place in the tension force of hoist cable 1 because of the emergency braking of lift car or the passenger in the lift car jump etc. action describe.
Under the wall bonded assembly situation of hoist cable end anchor fitting and hoist trunk, when hoist cable 1 come-up, hoist cable 1 produces the power that hoist cable end anchor fitting is mentioned.This mentions power is the power that sleeve 5 is mentioned toward the top, and when the friction coefficient between wedge-like member 2 and sleeve 5 was abundant inadequately, wedge-like member 2 was with respect to sleeve 5 come-ups.Therefore, the pressing force of 2 pairs of hoist cables 1 of wedge-like member reduces, and hoist cable 1 can break away from sleeve 5.At this moment, owing to wedge-like member 2 is pushed towards little opening portion 53 by controlling member 3 and elastic component 4, thus wedge-like member 2 clamping hoist cable 1 early, thus the disengaging of hoist cable 1 can be controlled at minimum limit.
On the other hand, under hoist cable end anchor fitting was fixed on situation on lift car and the counterbalanced weight, sleeve 5 produced displacement because of the emergency braking of lift car and the passenger in the lift car jump etc.At this moment, owing to wedge-like member 2 moves towards big opening portion 52 directions, so the Clamping force of hoist cable 1 is descended.Therefore, hoist cable 1 will come off from sleeve 5, but because under the effect of controlling member 3 and elastic component 4, wedge-like member 2 also carries out clamping thereupon moving to hoist cable 1 when hoist cable 1 moves, comes off so can prevent hoist cable 1.
According to first embodiment, come clamping hoist cable 1 by the wedge-like member 2 that is divided into two, can be under the state that does not make hoist cable 1 bending fixing hoist cable 1, thus, can prevent that hoist cable 1 is crushed.So, be crushed by preventing hoist cable 1, the bundled steel wires that can avoid having carried out with resin the end of the hoist cable 1 that applies is twisted thigh bundle 13 comes in contact each other, thereby can carry out high-precision inspection to hoist cable 1 by measuring resistance.
Fig. 5 is the section drawing of second embodiment of expression hoist cable end anchor fitting involved in the present invention.With the above-mentioned identical part employing symbolic representation identical of part shown in Figure 1 with Fig. 1.
In the above-described embodiment, as shown in Figure 1, be described as the situation of elastic component 4 using coil spring, but the present invention is not limited to this, as shown in Figure 5, as elastic component 40, for example can use disc spring to be used as elastic component.Disc spring is compared with coil spring, can obtain bigger load with less deflection.Therefore, by using disc spring, can shorten wedge-like member 2 and control distance between the member 3, and then can shorten the length dimension of sleeve 5.In addition, except disc spring, also can use leaf spring.
Fig. 6 is the section drawing of the 3rd embodiment of expression hoist cable end anchor fitting involved in the present invention.With the above-mentioned identical part employing symbolic representation identical of part shown in Figure 1 with Fig. 1.
As shown in Figure 6, in the anchor fitting of the hoist cable end of the 3rd embodiment, sleeve 50 is provided with the window 501 that is communicated with the inner space of sleeve 50.
In the anchor fitting of the hoist cable end of the 3rd embodiment, when hoist cable 1 being fixed on the anchor fitting of hoist cable end, push wedge-like member 2 from the bar-shaped instrument of window 501 usefulness then at first wedge-like member 2 and hoist cable 1 are packed into the inside of sleeve 50 towards little opening portion 53.At this moment, by 2 wedge-like members 2 are pressed into identical amount towards little opening portion 53 respectively, can avoid the hoist cable Clamping force of wedge-like member 2 only to take place in monolateral actv. situation.
Owing to bear compressive load all the time by the hoist cable 1 of wedge-like member 2 clampings,, make the diameter of hoist cable reduce so inner layer resin 16 and outermost resin 17 slowly are out of shape from wedge-like member 2.At this moment, hoist cable 1 and wedge-like member 2 are towards little opening portion 53 direction displacements, and wedge-like member 2 increases from little opening portion 53 outstanding overhangs.When the decrease of hoist cable diameter with respect to each wedge-like member 2 respectively not simultaneously, wedge-like member 2 deviation occurs between the outstanding overhang of little opening portion 53, the Clamping force of 2 pairs of hoist cables of wedge-like member reduces.Therefore, by checking, can install again hoist cable end anchor fitting in suitable period from the position of 501 pairs of wedge-like members 2 of window.
In addition, can measure by the deflection of 501 pairs of elastic components 4 of window, thereby can check the Clamping force of wedge-like member 2 and the hold of controlling member 3.That is to say that hoist cable 1 is by 2 clampings of wedge-like member, it is unusual and when causing the Clamping force of wedge-like member 2 decline to occur damage etc. to have occurred at outermost resin 17, hoist cable 1 from sleeve 5 by towards little opening portion 53 towings.Therefore, the deflection that is installed in the elastic component 4 between wedge-like member 2 and the retaining member 3 reduces.Check the deflection of these elastic components 4 from window 501, when this deflection when the deflection of regulation is following, the Clamping force that is judged as wedge-like member 2 reduces, thereby can install again hoist cable end anchor fitting in suitable period.
In addition, do not change, but the deflection of elastic component 4 is judged as the hold of controlling 3 pairs of hoist cables of member and reduces when specified value is above, thereby can control member 3 and elastic component 4 is installed again from 501 pairs of windows in the position of wedge-like member 2.
