[embodiment 1]
As shown in Figure 1, the hoist cable holding device of the 1st embodiment is made of clamp-type wedge-like member 2, convoluted wedge-like member 3, anchor clamps 4 and sleeve 5 that hoist cable 1 is banded together.Wherein, this clamp-type wedge-like member 2 is divided into a plurality of parts, and be configured to clamping hoist cable 1, on one's body this convoluted wedge-like member 3 is wound on hoist cable 1 certainly, this hoist cable of clamping between sleeve 5 and convoluted wedge-like member 3 thus, the inside of this sleeve 5 is inserted with clamp-type wedge-like member 2, convoluted wedge-like member 3 and anchor clamps 4.The top of sleeve 5 is equipped with pin 8 and collar bar 9, and as shown in Figure 6 and Figure 7, the hoist cable holding device is fixed on the wall of lift car, counterbalanced weight or hoist trunk.In addition, as shown in Figure 1, sleeve 5 has for the through hole 505 of clamp-type wedge-like member 2 insertions, for the big opening portion 502 of convoluted wedge-like member 3 insertions and the little opening portion 503 that enters for hoist cable 1.
Fig. 2 is the block diagram of the hoist cable holding device of Fig. 1, by the through hole 505 that is opened on the sleeve 5 anchor clamps 4 is installed in the sleeve 5, and takes out the hoist cable end 111 that is connected to conducting detector 703 from this through hole 505.In addition, through hole 505 is opened on two faces of sleeve, makes it possible to erection work of carrying out from former and later two directions by hoist cable etc., can improve operation thus.
As shown in Figure 3, clamp-type wedge-like member 2 is divided into a plurality of parts (for example being divided into two parts), and it is configured to clamping hoist cable 1.Clamp-type wedge-like member 2 comes clamping and fixing hoist cable 1 by the pressing force from the wedge-like member bearing surface (dip plane) 501 of sleeve 5 inboards.And the face that contacts with hoist cable 1 of clamp-type wedge-like member 2 is provided with the curved surface 201 that the external diameter shape with hoist cable 1 matches.In addition, as shown in Figure 3, for example by implementing embossing processing at curved surface 201, can improve the friction coefficient between hoist cable 1 and the clamp-type wedge-like member 2, can prevent that thus sliding from appearring in hoist cable.In addition, in the present embodiment, be described to be processed as example in curved surface 201 enforcement embossing, but also can carry out other processing, for example carry out sandblast processing.
As shown in Figure 4, convoluted wedge-like member 3 is formed by straight-line groove 301 and curved groove 302.In order to prevent that hoist cable 1 is crushed when the coiling hoist cable 1, according to and the diameter of hoist cable 1 between relation determine the radius of curvature of curved groove 302.
Because the anchor clamps 4 of Fig. 1 need be fixed in the mode that has abundant friction force with respect to hoist cable 1, so it is configured to have interface, with the fastening amount of restriction bolt when suppressing hoist cable 1 as much as possible and being crushed.
As shown in Figure 5, hoist cable 1 is by forming strand (strand) 102 with steel wire (wire) 101 twisteds, and strand 102 twisteds being become the strand bundle again is strand group (schenkel) 103, after this further cord yarn group and forming.Be provided with core strand group 104 at the center of hoist cable 1, the circumferencial direction along hoist cable around core strand group 104 equally spaced is provided with a plurality of sidepiece strand groups 105.Be filled with the inner layer resin 106 that for example is made of polyurethane between core strand group 104 and sidepiece strand group 105, under normal conditions, the strand bundle is that the strand group can not come in contact each other.In addition, around sidepiece strand group 105, be provided with the outermost resin 107 that is for example constituted by polyurethane.So, because strand group 103 is by outermost resin 107 coatings, so under the protection of outermost resin 107, strand group 103 can not come in contact with other strands group and rope sheave.
Maintenance step when below explanation uses the hoist cable holding device of present embodiment to keep hoist cable.
When hoist cable 1 is connected with this holding device, clamp hoist cable 1 by clamp-type wedge-like member 2.And, from little opening portion 503 towing hoist cables 1.By towing hoist cable 1, the direction towards little opening portion 503 moves hoist cable 1 from sleeve inner.Because clamp-type wedge-like member 2 moves to little opening portion 503 along the wedge-like member bearing surface 501 that is formed by the dip plane, so hoist cable 1 is held 2 clampings of type wedge-like member.When the friction force between clamp-type wedge-like member 2 and the hoist cable 1 during greater than the friction force between clamp-type wedge-like member 2 and the wedge-like member bearing surface 501, clamp-type wedge-like member 2 moves towards little opening portion 503 with hoist cable 1, when the antagonistic force that produces when hoist cable 1 is compressed and the pressing force of clamp-type wedge-like member 2 balanced each other, clamp-type wedge-like member 2 stopped mobile.
After this, insert convoluted wedge-like member 3 from big opening portion 502, simultaneously along straight-line groove 301 and curved groove 302 coiling hoist cables 1, and hoist cable end 111 taken out from through hole 505.The dip plane of the sleeve 5 that correspondingly forms with convoluted wedge-like member 3 constitutes the bearing surface 504 of convoluted wedge-like member 3, between this bearing surface 504 and convoluted wedge-like member 3 hoist cable 1 is applied Clamping force.
Then, clamp hoist cable 1 by anchor clamps 4.In addition, for fear of convoluted wedge-like member 3 hoist cable 1 is flattened, fixedly the time, make the 110 generation deflections of hoist cable middle part, thereby prevent from being wound on the influence that hoist cable on the convoluted wedge-like member 3 is subjected to tension force.
According to the 1st embodiment, clamp hoist cable 1 by the clamp-type wedge-like member 2 that is divided into two parts, can under the state that does not make hoist cable 1 bending, fix hoist cable 1, thereby can prevent that hoist cable 1 is crushed.
But, owing to come clamping hoist cable 1 by clamp-type wedge-like member 2, so the outermost resin 107 of hoist cable 1 bears friction force at curved surface 201 places of clamp-type wedge-like member 2.This friction force acts on the outermost resin 107 repeatedly, may cause outermost resin 107 to be peeled off.After outermost resin 107 was peeled off, hoist cable 1 can get off from clamp-type wedge-like member 2 in landing, and at this moment, load will be born in hoist cable middle part 110.When load is born at hoist cable middle part 110, this load produces the power that hoist cable 1 is come off from convoluted wedge-like member 3, but because hoist cable is clamped by anchor clamps 4, and the dip plane that is wound type wedge-like member 3 and sleeve 5 is bearing surface 504 clampings, so, can prevent that hoist cable 1 from coming off from sleeve 5 by convoluted wedge-like member 3 and anchor clamps 4.So, be crushed by preventing hoist cable 1, can avoid the strand bundle occurring in the hoist cable end 111 of the hoist cable 1 that is coated with resin is the situation that strand group 103 comes in contact each other, thus, can use conducting detector that hoist cable 1 is carried out high-precision inspection.
[embodiment 2]
Fig. 8 is the section drawing of the 2nd embodiment of expression hoist cable holding device involved in the present invention.In Fig. 8, the part identical with above-mentioned Fig. 1 adopts identical symbolic representation.
As shown in Figure 8, the hoist cable holding device of the 2nd embodiment by clamp-type wedge-like member 2, clamp hoist cable 1 clamp member 6, elastic body 10, convoluted wedge-like member 3 and sleeve 5 of coiling hoist cable 1 constitutes on it, wherein, clamp-type wedge-like member 2 is divided into a plurality of parts, and be configured to clamp hoist cable 1, elastic body 10 is inserted in clamp-type wedge-like member 2 and clamps between the member 6, described clamp-type wedge-like member 2, clamps the inside that member 6, elastic body 10 and convoluted wedge-like member 3 are arranged on sleeve 5.In addition, pin 8 is installed in the top of sleeve 5, and collar bar 9 is fixed on the pin 8, and as shown in Figure 6 and Figure 7, the hoist cable holding device is connected with the wall of lift car, counterbalanced weight or hoist trunk.
As shown in Figure 9, clamp member 6 and for example be divided into 2 members that are divided into two, it is configured to make the interface of 2 members to contact, and is combined into one to clamp hoist cable 1 by bolt 601.Be specifically, make interface 602 contact by binding bolt 601, when can position in the position to the hoist cable clamping surface 603 of clamping member 6 thus, avoid being crushed because bolt 601 excessive tightness cause hoist cable 1.In addition, clamping member 6 need fix in the mode that has abundant friction force with respect to hoist cable 1 when suppressing hoist cable 1 as much as possible and being crushed.Therefore, in order to increase the friction coefficient between hoist cable clamping surface 603 and the hoist cable 1, can also implement embossing processing or sandblast processing.
As shown in Figure 8, as elastic component 10, for example use the coil spring that produces elastic force by compression.Though use coil spring as elastic component 10 in the present embodiment, the present invention is not limited to this, for example also can use disk spring as elastic component.Disk spring is compared with coil spring, can obtain bigger load with less deflection.Therefore, by using disk spring, can shorten clamp-type wedge-like member 2 and clamp distance between the member 6, and then can shorten the length dimension of sleeve 5.In addition, except disk spring, can also use leaf spring.
At the hoist cable holding device of the 2nd embodiment, below the action that taken place when lax of vibration when the tension force of hoist cable 1 run in the lift car etc. because of emergency braking, the passenger of lift car describe.Be connected at the hoist cable holding device under the situation on the wall of hoist trunk, when hoist cable 1 floated up, hoist cable 1 produced the power that the hoist cable holding device is lifted towards the top.This power with sleeve 5 towards above when lifting, if do not have enough friction coefficient between clamp-type wedge-like member 2 and the sleeve 5, then clamp-type wedge-like member 2 floats towards the top with respect to sleeve 5.Thus, the pressing force of 2 pairs of hoist cables 1 of clamp-type wedge-like member reduces, and makes hoist cable 1 come off from sleeve 5.At this moment, by clamping member 6 and elastic component 10 clamp-type wedge-like member 2 is pressed towards little opening portion 503, made clamp-type wedge-like member 2 clamp hoist cable 1 in time thus, thereby coming off of hoist cable 1 can be limited in minimum zone.
On the other hand, when the hoist cable holding device was fixed on lift car and the counterbalanced weight, owing to reasons such as the emergency braking of lift car and passenger run, sleeve 5 can produce displacements.At this moment, owing to clamp-type wedge-like member 2 moves towards big opening portion 502 directions, and cause the Clamping force of hoist cable 1 is weakened.At this moment, hoist cable 1 moves towards the direction that comes off from sleeve 5, but under the effect of clamping member 6 and elastic body 10, clamp-type wedge-like member 2 moves and clamp hoist cable 1 when hoist cable 1 moves, comes off so can prevent hoist cable 1.
The present invention is not limited in above-described embodiment, for example also can and with anchor clamps shown in Figure 14 and the member 6 of clamping shown in Figure 8, can further strengthen the maintenance to hoist cable 1 thus, and the raising safety.Be specifically, use clamp-type wedge-like member 2 to come clamping hoist cable 1, clamp hoist cable 1 by the member 6 of clamping shown in Figure 8 then.After this, after hoist cable 1 being wound on the convoluted wedge-like member 3, clamp hoist cable 1 by anchor clamps 4, can further keep hoist cable 1 effectively thus.
