1379045 鋼索1脫落。 根據第1實施形態時，鋼索1是被夾入在分割成2個 的楔構件2,藉此不用彎曲鋼索1就能夠固定鋼索1，因 此能夠防止鋼索1被壓扁。如此一來，防止鋼索1被壓扁 ，就能夠避免成爲樹脂包覆的鋼索1端部的芯線束即繩束 綑13彼此的接觸，藉此就能夠精度良好實施使用電阻進 行鋼索1的檢查。 第5圖爲表示本發明相關的鋼索終端固定裝置第2實 施形態的剖面圖。另外，與上述第1圖所示構件同等的構 件是標示同一圖號。 上述的實施形態，如第1圖所示，彈性構件4是使用 螺旋彈簧，但本發明並不限於此，如第5圖所示，彈性構 件40，例如也可使用盤簧做爲彈性構件。盤簧，其與螺 旋彈簧相比能夠以短的撓度獲得較大的荷重。因此，使用 盤簧能夠縮短楔構件2和把持構件3的距離，進一步可縮 短套筒5的長度尺寸。另，除了盤簧以外，還可使用板簧 〇 第6圖爲表示本發明相關的鋼索終端固定裝置第3實 施形態的剖面圖。另外，與上述第1圖所示構件同等的構 件是標示同一圖號。 第3實施形態的鋼索終端固定裝置，如第6圖所示， 於套筒50設有和其內部空間連通的窗口 501。 第3實施形態的鋼索終端固定裝置，在將鋼索丨固定 在鋼索終端固定裝置時，首先，將楔構件2和鋼索1放入 -12- 1379045 套筒50內’使用棒狀工具從窗口 501將楔構件2推向小 開口部53。此時，只要讓成爲2個的楔構件2分別以同 量推向小開口部53就能夠避免楔構件2的鋼索夾持力偏 向單側。 此外，由楔構件2所夾持的鋼索I，因經常會受到楔 構件2的壓縮荷重’所以內層樹脂16及外層樹脂17會逐 漸變形，以致鋼索直徑減少。於該狀況時，鋼索1及楔構 件2會往小開口部53方向位移，使楔構件2從小開口部 53露出的量增加。當鋼索直徑的減少量對各楔構件2呈 現不同量時’楔構件2從小開口部53露出的量就會有差 異’導致楔構件2的鋼索夾持力降低.。因此，利用窗口 5〇1檢査楔構件2的位置，能夠在適當時期實施鋼索終端 固定裝置的再安裝。 再加上，透過窗口 501測定彈性構件4的撓曲量能夠 檢查楔構件2的夾·持力及把持構件3的把持力。即，鋼索 1雖然是由楔構件2夾持著，但外層樹脂17的損傷等異 常造成楔構件2的夾持力降低時，鋼索1可從套筒5拉向 小開口部5 3。因此，就能夠使安裝在楔構件2和把持構 件3之間的彈性構件4的撓曲量減少。從窗口 501檢查該 彈性構件4的撓曲量，當成爲指定撓曲量以下時，就可判 定楔構件2的夾持力減少，能夠在適當時期實施鋼索終端 固定裝置的再安裝。 再加上，雖然楔構件2的位置沒有改變，但彈性構件 4的撓曲量已成爲指定値以上時，就可判定把持構件3的 -13- 1379045 鋼索把持力降低’從窗口 501能夠實施把持構件3及彈性 構件4的再安裝。 【圖式簡單說明】 第1圖爲表示本發明相關的鋼索終端固定裝置第1實 施形態的剖面圖。 第2圖爲第1圖鋼索終端固定裝置所使用的楔構件的 透視圖。 第3圖爲第1圖鋼索終端固定裝置所使用的把持構件 的剖面圖。 第4圖爲鋼索終端固定裝置所要固定的對象的鋼索剖 面圖。 第5圖爲表示本發明相關的鋼索終端固定裝置第2實 施形態的剖面圖。 第6圖爲表示本發明相關的鋼索終端固定裝置第3實 施形態的剖面圖》 【主要元件符號說明】 1 :鋼索 Π :芯線 1 2 :繩束 13 :繩束綑 14 :芯繩束綑 1 5 :側繩束綑 -14- 1379045 1 6 :內層樹脂 1 7 :外層樹脂 2 :楔構件 21 :曲面 3 :把持構件 3 1 :螺絲 3 2 :對接面 33 :鋼索把持面 4、4 0 :彈性體 5 ' 50 :套筒 5 1 :承楔面 5 2 :大開口部 5 3 :小開口部 501 :窗口 6 :插銷 7 :嵌環桿 -15-139. The invention relates to a cable terminal fixing device for fixing an elevator cable terminal at a designated portion. [Prior Art] A cable-type elevator that uses a steel cable for the main form of an elevator is constructed as a sheave to which a wire rope is hung on a hoist, and the elevator cage is hanged on one side with the sheave as a center, and the opposite side hoist Hang the counterweight that can be balanced with the elevator cage. The cable is inserted into the steel sleeve through the bearing alloy, or it is fixed to the elevator cage and the counterweight by the wedge sleeve of the steel wedge through the steel sleeve or fixed to the wall of the hoistway. However, in recent years, belts or steel cables coated with excellent softness resin have been developed based on the miniaturization of the hoisting machine or the reduction of the diameter of the sheave. The above-mentioned belt or cable is filled with a resin bundle formed by twisting the core wires to prevent the core bundles from coming into contact with each other, thereby realizing a long life of the belt or the cable. A resin-coated belt or cable may cause wear due to core wire fatigue or core wire sliding relative to each other due to bending of the pulley or the sheave, and resin wear caused by relative sliding of the sheave groove causes damage end life. . These belts and steel cables are covered with a resin, so that the damage of the inner core wire cannot be visually inspected. Therefore, the inspection method of the core wire damage is a resistance test. The inspection method is, for example, a method of removing the resin from the end of the wire connected to the wall of the elevator cage, the counterweight or the hoistway, connecting the core bundle to the power source, and measuring the resistance by flowing a current to thereby check the damage of the core. That is, if the core wire is broken, the total cross-sectional area of the core bundle -5 - 1379045 is reduced and the electric resistance is increased, so that the damage of the core wire can be detected by measuring the resistance. Then, it has been known that the steel wire is fixed at the end by a wedge member and a sleeve, and the steel cable is folded back along the wedge member, and the steel wire is held by the sleeve and the wedge member (for example, refer to Patent Document 1). Further, a fixing device for a belt end portion coated with a resin has been proposed to insert and fix a mosaic material between the sleeve and the wedge member in order to uniformly distribute the pressure when the belt is clamped by the wedge member (for example, Refer to Patent Document 2). [Patent Document 1] Japanese Laid-Open Patent Publication No. 2001-165245 (Patent Document 2) Japanese Laid-Open Patent Publication No. Hei No. 2005-502562 [Draft of the Invention] However, the prior art of the former is that the steel cable is closely attached. When the wedge member is bent and the bending portion is loaded with tension, the cable cross section is compressed and flattened. In addition, the cable clamp uses a pair of clamping plates, but if the bolts of the clamping plate are excessively locked, the cable will also be flattened. In addition, the latter technique is to bend the belt against the wedge member to form a small diameter. However, since the cross-sectional shape of the belt is rectangular, the compression deformation at the time of bending is small. However, if the cable is used in this technique, the profile will become flat due to the circular cross-sectional shape of the cable. However, as the cable used in the elevator described above, the core bundles are filled with a resin, and the core bundles are prevented from coming into contact with each other. However, if the steel cables are crushed, the surface pressure of the core bundles increases, so that the charge is increased. The 1379045 resin between the core bundles is excluded so that the core bundles come into contact with each other. As a result, the resistance changes as the different core bundles come into contact with each other. Therefore, when the core damage inspection is performed, it is impossible to distinguish the resistance change due to the damage of the core wire or the contact of the core harness, which causes a problem that it is difficult to perform high-precision inspection. The present invention is an invention based on the above-described prior art, and an object of the invention is to provide a cable terminal fixing device capable of preventing a flat cable from being flattened [means for solving the problem]. According to a second aspect of the invention, a cable terminal fixing device includes: a wedge member that is disposed to sandwich a steel cable; a grip member for gripping the cable end portion; and an elastic body that is inserted between the wedge member and the grip member; And the wedge member, the grip member, and the sleeve into which the elastic body is to be inserted, wherein the grip member contacts the mating surface of the two or more members and holds the wire by the wire holding surface, and the wire is made of metal The bundle of the core strands is twisted to form a bundle of core bundles, that is, a bundle of bundles, and the bundle of bundles is twisted and formed, and a bundle of core bundles is disposed at the center, and a plurality of bundles of the side bundles are arranged around the circumference, The side rope bundle and the bundle of the above-mentioned core rope are filled with an inner resin 'and an outer layer is provided around the side bundle bundle a grease having a curved surface formed along an outer diameter shape of the steel wire on a surface contacting the steel wire of the wedge member, and performing a scoring process on the curved surface or sandblasting, wherein the holding member is held by the wire rope The surface is nicked, 1379045 or sandblasted. According to the first aspect of the invention of the present invention, since the wedge member is formed by sandwiching the steel cable, the cable can be fixed without bending, so that the cable can be prevented from being flat. In addition, the steel cable is fixed to the wedge member and the holding member, and the elastic member is provided between the wedge member and the holding member, so that the emergency braking of the elevator cage can be dealt with, or the steel cable caused by the passenger jumping in the elevator cage can be dealt with. The tension is relaxed and the cable can be prevented from falling off. Further, since the cable is held by the contact of the abutting faces of the respective members divided into two or more grip members, the cable can be prevented from being crushed. [Effect of the Invention] According to the present invention, the cable can be prevented from being crushed. The ends of the steel cord coated with the resin prevent the core strands from coming into contact with each other, so that the cable inspection using the electric resistance can be performed with high precision. [Embodiment] BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a wire rope terminal fixing device according to the present invention will be described with reference to the drawings. Fig. 1 is a cross-sectional view showing a first embodiment of a cable terminal fixing device according to the present invention, Fig. 2 is a perspective view showing a wedge member used in the cable fixing device of Fig. 1, and Fig. 3 is a fixing of a cable terminal in Fig. 1. Sectional view of the gripping member used in the apparatus-8- 1379045, and Fig. 4 is a sectional view of the cable of the object to be fixed by the cable terminal fixing device. The cable terminal fixing device according to the first embodiment, as shown in Fig. 1, is: a wedge member 2 which is divided into a plurality of pieces and which is formed with the cable 1 interposed therebetween; a grip member 3 for gripping the end of the cable 1; an elastic body 4 inserted between the wedge member 2 and the grip member 3; and a wedge member 2 and a grip member 3 And the sleeve 5 to be inserted into the elastic body 4, and the insertion rod 7 is fixed to the bolt 6 attached to the upper portion of the sleeve 5, and is connected to an elevator cage, a counterweight, or a hoistway wall (not shown). . The wedge member 2 is divided into two, for example, and divided into two, and is formed by arranging the cable 1 interposed therebetween, and is fixed by sandwiching the wire 1 by a pressing force that receives the wedge receiving surface 51 from the inside of the sleeve 5. Further, a curved surface 21 formed along the outer diameter shape of the wire rope 1 is provided on a surface of the wedge member 2 that is in contact with the wire rope 1. Next, as shown in Fig. 2, the curved surface 21 is subjected to, for example, scoring processing, thereby increasing the coefficient of friction between the cable 1 and the wedge member 2 to prevent slippage. Further, in the present embodiment, the surface of the curved surface 2 1 is exemplified by the scoring process, but the curved surface 2 1 may be subjected to other processing, for example, by sandblasting. As shown in Fig. 3, the grip member 3 is disposed, for example, so that the abutting faces of the two divided members can be brought into contact with each other, and the steel wire 1 is integrally held by the screws 31. That is, when the locking screw 31 brings the abutting surface 32 into contact, the position of the wire gripping surface 33 of the gripping member 3 can be determined, and the excessively locking of the screw 31 can be prevented to cause the cable 1 to be crushed. Further, the grip member 3 needs to be able to suppress the flattening of the cable 1 as much as possible, and also requires sufficient friction to fix the cable 1. Therefore, it is also possible to apply the scoring or sandblasting for the increase in the friction coefficient between the wire holding surface 33 and the -9- 1379045 wire 1. The elastic member 4, as shown in Fig. 1, is, for example, a coil spring that generates elasticity by compression. As shown in Fig. 1, the sleeve 5 has a large opening portion 52 for inserting the wedge member 2, and a small opening portion 53 for pulling out the cable 1. The wire rope 1, as shown in Fig. 4, twists the metal core 11 to form a rope bundle 12, and twists it to form a core bundle, that is, a rope bundle 13, and twists the bundle 13 to form a steel cord 1. The core bundle bundles 14 are disposed at the center of the cable 1, and a plurality of side bundle bundles 15 are arranged at equal intervals in the circumference of the cable. The side bundle bundles 1 5 and the bundles of core bundles are filled with, for example, The inner layer resin 16 formed of polyurethane, usually, the core bundle, that is, the bundle of bundles, does not make contact with each other. Further, an outer layer resin 17 made of, for example, polyurethane is provided around the side bundle bundle 15. As a result, the bundle of ropes 13 is covered by the outer layer of resin 17, protecting the contact with the other bundles of ropes and the sheaves. Next, a wire fixing step using the wire end fixing device of the present embodiment will be described. When the cable 1 is connected to the wire terminal fixing device, first, the wire rope 1 is sandwiched by the two holding members 3, and the holding member 3 is fixed by the screws 31. Next, the elastic member 4 is bent to a predetermined displacement amount to be attached to the holding member 3, and the wedge member 2 is pushed to the elastic member 4 while the steel wire 1 is sandwiched by the wedge member 2. Next, the wire rope 1, the wedge member 2, the holding member 3, and the elastic member 4 are inserted into the sleeve 5, and the wire rope 1 is pulled out from the small opening portion 53. When the wire rope 1 is pulled out, the wire rope 1 and the holding member 3 move from the inside of the sleeve to the small opening portion 53 side. At this time, the wedge member 2 and the grip member 3 compress the -10- 1379045 elastic member 4, and the elastic member 4 moves the wedge member 2 in the direction of the small opening portion 53. Since the wedge member 2 is moved toward the small opening portion 53 along the wedge receiving surface 51, the wire rope 1 is held by the wedge member 2. When the frictional force of the wedge member 2 and the cable 1 is greater than the frictional force of the wedge member 2 and the wedge receiving surface 51, the wedge member 2 moves toward the small opening portion 53 simultaneously with the cable 1, and the rebound caused by the compression of the cable 1 When the pressing force of the force and the wedge member 2 are equal, the wedge member 2 stops moving. Here, the operation of the wire rope terminal fixing device according to the present embodiment in the case where the elevator cage is in an emergency braking or when the tension of the cable 1 is relaxed due to a passenger jump or the like in the elevator cage will be described. When the cable end fixture is connected to the wall of the hoistway, if the cable 1 is suspended, the cable 1 operates to lift the force of the cable termination fixture. This force causes the sleeve 5 to be lifted up, but if the friction coefficient of the wedge member 2 and the sleeve 5 is insufficient, the wedge member 2 is suspended in the sleeve 5. Therefore, the pressing force applied to the wire rope 1 by the wedge member 2 is reduced, and the wire rope 1 is detached from the sleeve 5. At this time, the grip member 3 and the elastic member 4 push the wedge member 2 against the small opening portion 53, so that the wedge member 2 can be gripped with the cable 1' at an early stage to minimize the fall of the cable 1. On the other hand, when the cable terminal fixing device is fixed to the elevator cage and the balance hammer, the sleeve 5 is displaced based on the main factors such as the emergency braking of the elevator cage or the jumping of the passenger. At this time, since the wedge member 2 is moved in the direction of the large opening portion 52, the clamping force of the wire rope 1 is reduced. Therefore, the cable 1 is detached from the sleeve 5, but the grip member 3 and the elastic member 4 move the wedge member 2 while moving the cable 1 while moving the cable 1, so that the -11 - 1379045 cable 1 can be prevented from falling off. . According to the first embodiment, the wire rope 1 is sandwiched between the wedge members 2 divided into two, whereby the wire rope 1 can be fixed without bending the wire rope 1, so that the wire rope 1 can be prevented from being crushed. In this way, by preventing the cable 1 from being crushed, contact between the bundles 13 of the core bundles which are the ends of the resin-coated cable 1 can be avoided, whereby the inspection of the cable 1 using the electric resistance can be performed with high precision. Fig. 5 is a cross-sectional view showing a second embodiment of the wire rope terminal fixing device according to the present invention. Further, the members equivalent to those shown in the above first embodiment are denoted by the same reference numerals. In the above-described embodiment, as shown in Fig. 1, the elastic member 4 is a coil spring. However, the present invention is not limited thereto. As shown in Fig. 5, the elastic member 40 may be, for example, a coil spring as an elastic member. A coil spring, which is capable of obtaining a larger load with a short deflection as compared with a coil spring. Therefore, the distance between the wedge member 2 and the grip member 3 can be shortened by using the coil spring, and the length dimension of the sleeve 5 can be further shortened. Further, a leaf spring may be used in addition to the coil spring. Fig. 6 is a cross-sectional view showing a third embodiment of the wire rope terminal fixing device according to the present invention. Further, the members equivalent to those shown in the above first embodiment are denoted by the same reference numerals. In the cable terminal fixing device of the third embodiment, as shown in Fig. 6, the sleeve 50 is provided with a window 501 communicating with the internal space thereof. In the cable terminal fixing device of the third embodiment, when the cable sling is fixed to the cable end fixing device, first, the wedge member 2 and the cable 1 are placed in the -12- 1379045 sleeve 50, and the window 501 is used from the window 501. The wedge member 2 is pushed toward the small opening portion 53. At this time, if the two wedge members 2 are pushed to the small opening portion 53 by the same amount, the cable holding force of the wedge member 2 can be prevented from being biased to one side. Further, the wire I held by the wedge member 2 is often subjected to the compressive load of the wedge member 2, so that the inner layer resin 16 and the outer layer resin 17 are gradually deformed, so that the wire diameter is reduced. In this case, the wire rope 1 and the wedge member 2 are displaced in the direction of the small opening portion 53, and the amount by which the wedge member 2 is exposed from the small opening portion 53 is increased. When the amount of decrease in the diameter of the cable is different for each of the wedge members 2, the amount by which the wedge member 2 is exposed from the small opening portion 53 is different, resulting in a decrease in the cable holding force of the wedge member 2. Therefore, the position of the wedge member 2 is inspected by the window 5〇1, and the reattachment of the cable end fixing device can be performed at an appropriate timing. Further, by measuring the amount of deflection of the elastic member 4 through the window 501, the grip holding force of the wedge member 2 and the holding force of the grip member 3 can be checked. That is, although the wire rope 1 is sandwiched by the wedge member 2, the wire rope 1 can be pulled from the sleeve 5 to the small opening portion 53 when the damage of the outer layer resin 17 is abnormal or the clamping force of the wedge member 2 is lowered. Therefore, the amount of deflection of the elastic member 4 mounted between the wedge member 2 and the holding member 3 can be reduced. When the amount of deflection of the elastic member 4 is checked from the window 501, when the amount of deflection is less than or equal to the specified amount of deflection, the clamping force of the wedge member 2 can be determined to be reduced, and the cable terminal fixing device can be reinstalled at an appropriate timing. Further, although the position of the wedge member 2 is not changed, when the amount of deflection of the elastic member 4 has become a predetermined value or more, it can be determined that the holding force of the -13,790,945 cable of the holding member 3 is lowered, and the control can be performed from the window 501. Reinstallation of the member 3 and the elastic member 4.
