Description

吊索端部固定装置 Sling end fixture

技术领域technical field

本发明涉及一种在电梯中用于将吊索的端部固定在规定部位上的吊索端部固定装置。The present invention relates to a sling end fixing device for fixing the end of a sling to a predetermined position in an elevator.

背景技术Background technique

电梯的主要形式是使用绳状吊索的曳引式电梯，该等曳引式电梯被构造成将吊索卷绕到安装在卷扬机上的绳轮上，以绳轮为中心在一侧悬吊电梯轿厢，并在相反侧悬吊与电梯轿厢保持平衡用的平衡重。绳状吊索通过在钢制的套筒内浇注巴氏合金或者在钢制的套筒中使用钢制楔的楔状套筒固定在电梯轿厢和平衡重或者升降通道的壁面上。The main form of elevator is a traction elevator using a rope-like sling, which is constructed so that the sling is wound around a sheave mounted on a hoist and suspended on one side with the sheave as the center The elevator car, and the counterweight used to maintain balance with the elevator car is suspended on the opposite side. The rope sling is fixed to the elevator car and the counterweight or the wall of the hoistway by casting babbitt alloy in the steel sleeve or using a steel wedge wedge sleeve in the steel sleeve.

近年来，为了实现卷扬机的小型化以及缩小绳轮的直径等，已经开发出了用具有良好柔软性的树脂进行了涂覆的带状吊索和绳状吊索。在该等带状吊索和绳状吊索中，为了延长使用寿命，在由钢丝捻合而成的钢丝束彼此之间充填树脂，以防止钢丝束彼此之间发生接触。涂覆有树脂的带状吊索和绳状吊索因通过绳轮和滑轮时产生的弯曲所引起的钢丝疲劳、钢丝彼此之间的相对滑动所引起的磨耗以及与绳轮凹槽之间的相对滑动所引起的树脂的磨耗等而受到损伤，从而达到寿命。由于该等带状吊索和绳状吊索的外层涂覆有树脂，所以无法通过目视来检查内部钢丝的损伤，因此，作为检查钢丝损伤的方法，采用通过测定电阻来进行检查的方法。在这样的检查方法中，例如，除去连接在电梯轿厢和平衡重或者升降通道的壁面上的吊索的端部的树脂，使钢丝束与电源连接，使电流通过来测定电阻，由此来检查钢丝的损伤。也就是说，当钢丝断裂后，钢丝束的总截面积减少而导致电阻增加，所以，通过测定电阻能够检查出钢丝的损伤。In recent years, belt-shaped slings and rope-shaped slings coated with a resin having good flexibility have been developed for the purpose of downsizing hoisting machines and reducing the diameter of sheaves. In these belt-like slings and rope-like slings, in order to prolong the service life, resin is filled between bundles of steel wires twisted together to prevent the wire bundles from contacting each other. Resin-coated belt-like slings and rope-like slings due to wire fatigue caused by bending when passing through sheaves and pulleys, wear caused by relative sliding of wires against each other, and friction with the groove of the sheave The wear of the resin caused by relative sliding is damaged and the service life is reached. Since the outer layer of these belt slings and rope slings is coated with resin, it is impossible to visually inspect the damage of the inner wire, so as a method of inspecting wire damage, a method of inspection by measuring electrical resistance is adopted. . In such an inspection method, for example, the resin at the end of the sling connected to the elevator car and the counterweight or the wall surface of the hoistway is removed, the steel wire bundle is connected to a power source, and the resistance is measured by passing a current. Check for wire damage. In other words, when the steel wire is broken, the total cross-sectional area of the steel wire bundle decreases to cause an increase in electrical resistance, so damage to the steel wire can be detected by measuring the electrical resistance.

作为现有技术，已知有用楔状构件和套筒来固定吊索的端部，使吊索沿着楔状构件折返，由此通过套筒和楔状构件来夹持吊索的技术(例如参照专利文献1)。此外，作为涂覆有树脂的带状吊索的端部固定装置，已经提出有在通过楔状构件来夹持带状吊索时，为了使压力均匀地分布，将插入件插入在套筒和楔状构件之间来进行固定的方案(例如参照专利文献2)。As prior art, it is known that the ends of the sling are fixed with a wedge member and a sleeve, and the sling is folded back along the wedge member, thereby clamping the sling by the sleeve and the wedge member (for example, refer to patent documents 1). In addition, as an end fixing device of a resin-coated sling, there has been proposed that when the sling is clamped by a wedge-shaped member, an insert is inserted between the sleeve and the wedge in order to distribute the pressure evenly. A solution for fixing between components (for example, refer to Patent Document 2).

然而，在上述前者的现有技术中，由于使吊索沿着楔状构件弯折，并且有张力负载作用在弯折部分上，所以吊索的截面被压扁而变形为扁平形状。此外，在该现有技术中作为吊索夹持器使用一对夹持板，如果夹住夹持板的螺栓紧固得过紧，则吊索同样会被压扁。However, in the above-mentioned former prior art, since the sling is bent along the wedge member and a tension load acts on the bent portion, the cross section of the sling is crushed and deformed into a flat shape. Furthermore, in this prior art, a pair of clamping plates are used as the clamp for the sling, and if the bolts clamping the clamping plates are tightened too tightly, the sling will also be crushed.

另外，在后者的现有技术中，其将带状吊索沿着楔状构件弯曲成小直径，在带状吊索的情况下，由于其截面形状为长方形，所以弯曲时的压扁量小。可是，如果将该技术应用在绳状吊索上时，由于绳状吊索的截面形状为圆形，所以截面被压扁而变形为扁平形状。In addition, in the latter prior art, which bends the belt-shaped sling along the wedge-shaped member to a small diameter, in the case of the belt-shaped sling, since its cross-sectional shape is rectangular, the amount of flattening during bending is small . However, when this technique is applied to a rope-like sling, since the cross-sectional shape of the rope-like sling is circular, the cross-section is crushed and deformed into a flat shape.

在上述用于电梯的吊索中，在钢丝束之间充填有树脂以防止钢丝束彼此之间发生接触，但在吊索被压扁时，钢丝束之间的表面压力增加，充填在钢丝束之间的树脂被挤出，从而导致钢丝束彼此之间发生接触。在不同的钢丝束彼此之间发生接触后，电阻发生变化。因此，在进行钢丝损伤的检查时，无法区别电阻的变化是因为钢丝的损伤而造成的，还是因为钢丝束彼此之间的接触而造成的，从而存在难以进行高精度检查这一问题。In the above-mentioned sling for an elevator, resin is filled between the wire bundles to prevent the wire bundles from coming into contact with each other, but when the sling is crushed, the surface pressure between the wire bundles increases, and the resin filled in the wire bundles The resin between them is squeezed out, causing the strands to come into contact with each other. After the different strands come into contact with each other, the resistance changes. Therefore, when inspecting wire damage, it is impossible to distinguish whether the change in resistance is due to damage to the wire or due to contact between wire bundles, making it difficult to perform high-precision inspection.

具体实施方式Detailed ways

以下参照附图对本发明所涉及的吊索端部固定装置的实施方式进行说明。Embodiments of the sling end fixing device according to the present invention will be described below with reference to the drawings.

图1是表示本发明所涉及的吊索端部固定装置的第一实施方式的截面图，图2是用于图1的吊索端部固定装置的楔状构件的立体图，图3是用于图1的吊索端部固定装置的把持构件的截面图，图4是吊索端部固定装置的固定对象即吊索的截面图。1 is a sectional view showing a first embodiment of a sling end fixing device according to the present invention, FIG. 2 is a perspective view of a wedge-shaped member used in the sling end fixing device of FIG. 1 , and FIG. 1 is a sectional view of a holding member of the sling end fixing device, and FIG. 4 is a sectional view of a sling to be fixed by the sling end fixing device.

如图1所示，第一实施方式的吊索端部固定装置由被分割成多个部分且以夹住吊索1的方式设置的楔状构件2、对吊索1的端部进行把持的把持构件3、插入在楔状构件2和把持构件3之间的弹性体4以及可让楔状构件2、把持构件3以及弹性体4插入的套筒5构成，此外，销6安装在套筒5的上部，活动杆(thimble rod)7固定在销6上，该吊索端部固定装置与未图示的电梯轿厢和平衡重或者升降通道的壁面连接。As shown in FIG. 1 , the sling end fixing device according to the first embodiment includes a wedge-shaped member 2 which is divided into multiple parts and installed so as to sandwich the sling 1 , and a gripper for holding the end of the sling 1 . The member 3, the elastic body 4 inserted between the wedge-shaped member 2 and the holding member 3, and the sleeve 5 that allows the wedge-shaped member 2, the holding member 3, and the elastic body 4 to be inserted are constituted. In addition, the pin 6 is installed on the upper part of the sleeve 5 , movable bar (thimble rod) 7 is fixed on the pin 6, and this sling end fixing device is connected with the wall surface of unillustrated elevator car and counterweight or hoistway.

楔状构件2被分割成多个部分，(例如二个部分)，且以夹住吊索1的方式设置，通过从套筒5内侧的楔状承受面51受到的按压力来夹持以及固定吊索1。此外，在楔状构件2的与吊索1接触的面中设置有沿着吊索1的外径形状的曲面21。并且，如图2所示，例如在曲面21实施轧花加工，由此来提高吊索1与楔状构件2之间的摩擦系数，以防止出现打滑。另外，在本实施方式中以对曲面21实施轧花加工为例作了说明，但也可以进行其它加工，例如进行喷砂加工。The wedge-shaped member 2 is divided into a plurality of parts (for example, two parts), and is arranged to clamp the sling 1, and clamps and fixes the sling by the pressing force received from the wedge-shaped receiving surface 51 inside the sleeve 5. 1. In addition, a curved surface 21 along the outer diameter shape of the sling 1 is provided on the surface of the wedge-shaped member 2 that contacts the sling 1 . In addition, as shown in FIG. 2 , for example, embossing is performed on the curved surface 21 to increase the coefficient of friction between the sling 1 and the wedge member 2 to prevent slippage. In addition, in this embodiment, although the embossing process to the curved surface 21 was demonstrated as an example, it is also possible to perform other processes, for example, sandblasting.

如图3所示，把持构件3例如被一分为二地分割成二个构件，并且被设置成各个构件的对接面相接触，且通过螺钉31被一体化，以此来把持吊索1。具体来说是，通过对螺钉31进行紧固，使对接面32接触，不但能够对把持构件3的吊索把持面33进行定位，而且还能够避免因螺钉31被过度紧固而导致吊索1被压扁。此外，由于需要在尽可能抑制吊索1被压扁的同时，以相对于吊索1具有充分摩擦力的方式对把持构件3进行固定，所以，也可以为了增加吊索把持面33与吊索1之间的摩擦系数，而对吊索把持面33实施轧花加工或者喷砂加工。As shown in FIG. 3 , the gripping member 3 is divided into two parts, for example, and is installed so that the mating surfaces of the respective parts are in contact with each other, and is integrated with screws 31 to hold the sling 1 . Specifically, by tightening the screw 31 so that the butt surface 32 contacts, not only can the sling gripping surface 33 of the gripping member 3 be positioned, but also the sling 1 can be avoided due to excessive tightening of the screw 31. was squashed. In addition, since it is necessary to fix the gripping member 3 with sufficient frictional force with respect to the sling 1 while suppressing the sling 1 from being crushed as much as possible, it is also possible to increase the contact between the sling gripping surface 33 and the sling. 1, and embossing or sandblasting is performed on the sling grip surface 33 .

如图1所示，作为弹性构件4例如使用通过压缩而产生弹力的螺旋弹簧。As shown in FIG. 1 , as the elastic member 4 , for example, a coil spring that generates elastic force by compression is used.

如图1所示，套筒5具有供楔状构件2插入的大开口部分52和引出吊索1用的小开口部分53。As shown in FIG. 1 , the sleeve 5 has a large opening 52 into which the wedge member 2 is inserted and a small opening 53 for pulling out the sling 1 .

作为吊索1的形成方法，如图4所示，对金属丝11进行捻合而形成股线12，并且进一步对股线12进行捻合而形成钢丝束即捻合股束(schenkel)13，之后将捻合股束13捻合成吊索1。在吊索1的中心设置芯部捻合股束14，在其周围沿着吊索的周向以相等的间隔设置多个侧部捻合股束15。在侧部捻合股束15和芯部捻合股束14之间充填有例如由聚氨酯构成的内层树脂16，在通常情况下，钢丝束即捻合股束彼此之间不会发生接触。另外，在侧部捻合股束13的周围设置有例如由聚氨酯构成的外层树脂17。捻合股束13由外层树脂17覆盖，从而在树脂的保护下避免了与其它捻合股束以及绳轮发生接触。As the forming method of the sling 1, as shown in FIG. 4, the metal wires 11 are twisted to form a strand 12, and the strands 12 are further twisted to form a steel wire bundle, that is, a twisted strand (schenkel) 13, and then The twisted strands 13 are twisted into a sling 1 . A core twisted strand 14 is provided at the center of the sling 1, and a plurality of side twisted strands 15 are arranged around it at equal intervals along the circumferential direction of the sling. Between the side twisted strands 15 and the core twisted strands 14, an inner layer resin 16 made of, for example, polyurethane is filled, and usually the steel wire bundles, that is, the twisted strands, do not come into contact with each other. In addition, an outer layer resin 17 made of, for example, polyurethane is provided around the side twisted strands 13 . The twisted strands 13 are covered by an outer layer of resin 17, thereby avoiding contact with other twisted strands and the sheave under the protection of the resin.

以下对采用本实施方式的吊索端部固定装置的吊索的固定顺序进行说明。Next, the fixing procedure of the sling using the sling end fixing device of this embodiment will be described.

在将本实施方式的吊索端部固定装置与吊索1连接时，首先用二个把持构件3夹住吊索1，并用螺钉31固定住把持构件3。然后，以规定的变位量使弹性构件4挠曲，并将其安装在把持构件3上，此后将楔状构件2朝向弹性构件4按压，并用楔状构件2夹住吊索1。之后，将吊索1、楔状构件2、把持构件3以及弹性构件4一起插入套筒5内，从小开口部分53拉出吊索1。在拉出吊索1时，吊索1和把持构件3从套筒内部朝小开口部分53移动。此时，弹性构件4被楔状构件2以及把持构件3压缩，弹性构件4使楔状构件2朝小开口部分53的方向移动。随着楔状构件2沿着楔状承受面51朝小开口部分53移动，吊索1被楔状构件2夹住。当楔状构件2与吊索1之间的摩擦力变得大于楔状构件2与楔状承受面51之间的摩擦力时，楔状构件2与吊索1同时朝小开口部分53移动，在由吊索1的压缩引起的反弹力与楔状构件2的按压力平衡时，楔状构件2停止移动。When connecting the sling end fixing device of this embodiment to the sling 1 , first, the sling 1 is clamped by the two holding members 3 , and the holding members 3 are fixed by the screws 31 . Then, the elastic member 4 is bent by a predetermined amount of displacement and attached to the holding member 3 , after which the wedge-shaped member 2 is pressed toward the elastic member 4 , and the sling 1 is sandwiched by the wedge-shaped member 2 . Thereafter, the sling 1 , the wedge member 2 , the holding member 3 , and the elastic member 4 are all inserted into the sleeve 5 , and the sling 1 is pulled out from the small opening 53 . When the sling 1 is pulled out, the sling 1 and the holding member 3 move from the inside of the sleeve toward the small opening portion 53 . At this time, the elastic member 4 is compressed by the wedge member 2 and the holding member 3 , and the elastic member 4 moves the wedge member 2 toward the small opening 53 . As the wedge-shaped member 2 moves toward the small opening portion 53 along the wedge-shaped receiving surface 51 , the sling 1 is clamped by the wedge-shaped member 2 . When the frictional force between the wedge-shaped member 2 and the sling 1 becomes greater than the frictional force between the wedge-shaped member 2 and the wedge-shaped receiving surface 51, the wedge-shaped member 2 and the sling 1 move toward the small opening portion 53 at the same time. When the rebound force caused by the compression of 1 is balanced with the pressing force of the wedge-shaped member 2, the movement of the wedge-shaped member 2 stops.

以下对吊索1的张力因电梯轿厢的紧急制动或电梯轿厢内的乘客跳跃等而发生松弛时的本实施方式的吊索端部固定装置的动作进行说明。The operation of the rope end fixing device of the present embodiment when the tension of the rope 1 is loosened due to emergency braking of the elevator car or jumping of passengers in the elevator car will be described below.

在吊索端部固定装置与升降通道的壁面连接的情况下，当吊索1上浮时，吊索1产生将吊索端部固定装置提起的力。该提起力是将套筒5往上方提起的力，在楔状构件2与套筒5之间的摩擦系数不够充分时，楔状构件2相对于套筒5上浮。因此，楔状构件2对吊索1的按压力降低，吊索1会脱离套筒5。此时，由于通过把持构件3和弹性构件4将楔状构件2朝小开口部分53按压，所以楔状构件2能够及早地夹持吊索1，从而能够将吊索1的脱离控制在最小的限度。In the case where the sling end fastening is connected to the wall of the hoistway, when the sling 1 floats up, the sling 1 generates a force to lift the sling end fastening. This lifting force is a force to lift the sleeve 5 upward, and when the coefficient of friction between the wedge-shaped member 2 and the sleeve 5 is not sufficient, the wedge-shaped member 2 floats up relative to the sleeve 5 . Therefore, the pressing force of the wedge member 2 on the sling 1 is reduced, and the sling 1 is detached from the sleeve 5 . At this time, since the wedge-shaped member 2 is pressed toward the small opening 53 by the holding member 3 and the elastic member 4, the wedge-shaped member 2 can clamp the sling 1 early, thereby minimizing the detachment of the sling 1.

另一方面，在吊索端部固定装置固定在电梯轿厢以及平衡重上的情况下，套筒5因电梯轿厢的紧急制动和电梯轿厢内的乘客跳跃等而产生变位。此时，由于楔状构件2朝大开口部分52方向移动，所以对吊索1的夹持力下降。因此，吊索1要从套筒5脱落，但由于在把持构件3和弹性构件4的作用下，在吊索1移动的同时楔状构件2也随之移动而对吊索1进行夹持，所以能够防止吊索1脱落。On the other hand, when the sling end fixing device is fixed to the elevator car and the counterweight, the sleeve 5 is displaced due to emergency braking of the elevator car, jumping of passengers in the elevator car, and the like. At this time, since the wedge-shaped member 2 moves toward the direction of the large opening portion 52, the clamping force on the sling 1 decreases. Therefore, the sling 1 will fall off from the sleeve 5, but under the action of the holding member 3 and the elastic member 4, the wedge-shaped member 2 also moves along with the movement of the sling 1 to clamp the sling 1. It is possible to prevent the sling 1 from falling off.

根据第一实施方式，通过分割成二个的楔状构件2来夹持吊索1，能够在不使吊索1弯曲的状态下固定吊索1，由此，能够防止吊索1被压扁。如此，通过防止吊索1被压扁，能够避免用树脂进行了涂覆的吊索1的端部的钢丝束即捻合股束13彼此之间发生接触，从而能够通过测定电阻对吊索1进行高精度的检查。According to the first embodiment, the wire rope 1 can be fixed without bending the wire rope 1 by sandwiching the wire rope 1 by the wedge-shaped member 2 divided into two, thereby preventing the wire rope 1 from being crushed. In this way, by preventing the sling 1 from being crushed, it is possible to avoid contact between the steel wire bundles at the ends of the sling 1 coated with the resin, that is, the twisted strands 13, so that the sling 1 can be tested by measuring the electrical resistance.

在上述实施方式中，如图1所示，对使用螺旋弹簧作为弹性构件4的情况作了说明，但本发明并不仅限于此，如图5所示，作为弹性构件40，例如可以使用盘簧来作为弹性构件。盘簧与螺旋弹簧相比，能够以较小的挠曲得到较大的负载。因此，通过使用盘簧，能够缩短楔状构件2与把持构件3之间距离，进而能够缩短套筒5的长度尺寸。此外，除了盘簧以外，也可以使用板簧。In the above-mentioned embodiment, as shown in FIG. 1 , the case of using a coil spring as the elastic member 4 has been described, but the present invention is not limited thereto. As shown in FIG. 5 , as the elastic member 40, for example, a coil spring can be used. as an elastic member. A coil spring can obtain a larger load with less deflection than a coil spring. Therefore, by using the coil spring, the distance between the wedge-shaped member 2 and the holding member 3 can be shortened, and the length dimension of the sleeve 5 can also be shortened. In addition, instead of coil springs, leaf springs may also be used.

图6是表示本发明所涉及的吊索端部固定装置的第三实施方式的截面图。与上述图1所示的部分相同的部分采用与图1相同的符号表示。Fig. 6 is a cross-sectional view showing a third embodiment of the cable end fixing device according to the present invention. The same parts as those shown in FIG. 1 above are denoted by the same symbols as in FIG. 1 .

如图6所示，在第三实施方式的吊索端部固定装置中，在套筒50上设置有与套筒50的内部空间连通的窗户501。As shown in FIG. 6 , in the sling end fixing device of the third embodiment, a window 501 communicating with the inner space of the sleeve 50 is provided on the sleeve 50 .

在第三实施方式的吊索端部固定装置中，在将吊索1固定在吊索端部固定装置上时，首先将楔状构件2和吊索1装入套筒50的内部，然后从窗户501用棒状工具将楔状构件2朝小开口部分53按压。此时，通过将2个楔状构件2分别朝小开口部分53按入相同的量，能够避免楔状构件2的吊索夹持力只在单边有效的情况发生。In the sling end fixing device of the third embodiment, when the sling 1 is fixed on the sling end fixing device, firstly, the wedge-shaped member 2 and the sling 1 are installed inside the sleeve 50, and then the sling 1 is inserted from the window. 501 presses the wedge-shaped member 2 toward the small opening portion 53 with a rod-shaped tool. At this time, by pushing the two wedge-shaped members 2 into the small opening portion 53 by the same amount, it is possible to avoid the situation where the cable clamping force of the wedge-shaped member 2 is effective only on one side.

由于由楔状构件2夹持的吊索1始终承受来自楔状构件2的压缩负载，所以内层树脂16和外层树脂17慢慢变形，使得吊索的直径减小。此时，吊索1和楔状构件2朝小开口部分53方向变位，楔状构件2从小开口部分53突出的突出量增加。当吊索直径的减小量相对于各个楔状构件2分别不同时，楔状构件2从小开口部分53突出的突出量之间出现偏差，楔状构件2对吊索的夹持力降低。因此，通过从窗户501对楔状构件2的位置进行检查，能够在适当的时期对吊索端部固定装置重新进行安装。Since the sling 1 held by the wedge member 2 is always subjected to a compressive load from the wedge member 2, the inner layer resin 16 and the outer layer resin 17 are slowly deformed so that the diameter of the sling is reduced. At this time, the sling 1 and the wedge-shaped member 2 are displaced toward the small opening 53, and the protrusion amount of the wedge-shaped member 2 from the small opening 53 increases. When the decrease in diameter of the sling is different for each of the wedge members 2 , a deviation occurs between the amount of protrusion of the wedge 2 from the small opening portion 53 , and the clamping force of the wedge 2 to the sling decreases. Therefore, by checking the position of the wedge-shaped member 2 from the window 501, it is possible to reattach the wire end fixing device at an appropriate timing.

另外，能够通过窗户501对弹性构件4的挠曲量进行测定，从而能够检查楔状构件2的夹持力以及把持构件3的把持力。也就是说，吊索1由楔状构件2夹持，在外层树脂17出现了损伤等异常而导致楔状构件2的夹持力出现了下降时，吊索1从套筒5被朝向小开口部分53拉曳。因此，安装在楔状构件2与保持构件3之间的弹性构件4的挠曲量减少。从窗户501检查该弹性构件4的挠曲量，当该挠曲量在规定的挠曲量以下时，判断为楔状构件2的夹持力已降低，从而能够在适当的时期对吊索端部固定装置重新进行安装。In addition, the amount of deflection of the elastic member 4 can be measured through the window 501 , so that the clamping force of the wedge-shaped member 2 and the grasping force of the grasping member 3 can be inspected. That is, the sling 1 is clamped by the wedge-shaped member 2, and when the clamping force of the wedge-shaped member 2 decreases due to an abnormality such as damage to the outer layer resin 17, the sling 1 is pulled from the sleeve 5 toward the small opening 53. pull. Therefore, the amount of deflection of the elastic member 4 installed between the wedge member 2 and the holding member 3 is reduced. Check the amount of deflection of the elastic member 4 from the window 501. When the amount of deflection is below the specified amount of deflection, it is judged that the clamping force of the wedge-shaped member 2 has decreased, so that the end of the sling can be fixed at an appropriate time. Fixtures are reinstalled.

此外，在楔状构件2的位置没有发生变化，但弹性构件4的挠曲量在规定值以上时，判断为把持构件3对吊索的把持力已降低，从而能够从窗户501对把持构件3和弹性构件4重新进行安装。In addition, when the position of the wedge-shaped member 2 does not change, but the amount of deflection of the elastic member 4 is more than a predetermined value, it is judged that the gripping force of the gripping member 3 on the sling has decreased, so that the gripping member 3 and the gripping member 3 can be controlled from the window 501. The elastic member 4 is reinstalled.
