Description

  TECHNICAL FIELD The present invention relates to a rope hole closing device, and more particularly to an improvement of a rope hole closing device that closes a rope hole through which a hoisting rope penetrates, which is drilled on a floor surface of a machine room formed in an upper part of an elevator.

  FIG. 10A shows a schematic structural diagram of a conventional lifting type elevator 100. As a part of the building in which the elevator 100 is installed, a hoistway 104 is formed in which an elevator car 102 on which a person or a baggage actually rides moves up and down. In addition, a machine room 110 in which a hoisting motor 108 for hoisting a hoisting rope 106 connected to the elevator car 102 is installed at the uppermost part. One end of the hoisting rope 106 is fixed to the elevator car 102. On the other hand, the other end of the hoisting rope 106 is connected to a counterweight (not shown) via a sheave 112 and a wheel 12 that are driven by the hoisting motor 108. Therefore, the hoisting rope 106 is installed so as to pass through the rope hole 118 drilled in the floor surface 116 of the machine room 110. Note that the rope hole 118 is wound around the wall surface of the rope hole 118 even when the hoisting rope 106 is shaken or when a plurality of hoisting ropes 106 (for example, three, four, or more) are connected. The upper rope 106 is formed so as to be much larger than the diameter of the passing hoist rope 106 so that the upper rope 106 does not come into contact with the upper rope 106 so that the hoist rope 106 can penetrate freely.

  When maintenance and repair of the hoisting motor 108, sheave 112, and other components of the elevator 100 having such a configuration are performed, an operator enters the machine room 110 to work. In this case, the operator handles tools such as a spanner, replacement parts, bolts, screws, and the like. Depending on the elevator, a rope hole 120 is formed as shown in FIG. 10 (b) in order to prevent the tools and parts used during the operation as described above from dropping from the rope hole 118. There is. In this case, tools and parts can be prevented from rolling on the floor surface 116 and falling from the rope hole 118, but it is not possible to cope with dropping from above the rope hole 118.

  Accordingly, a rope hole closing device 122 that completely prevents the fall as shown in FIG. 11 has also been devised. The rope hole closing device 122 includes a pair of detachable closing members 124 having a size capable of sufficiently covering the rope hole 118 and an opening / closing mechanism 126 that slides the closing member 124 along the floor surface 116. (For example, belt drive). The closing member 124 is formed with a notch portion 124a for escaping the hoisting rope 106, and the closing member 126 is brought into close contact with both sides of the hoisting rope 106 from the both sides of the arrangement of the hoisting rope 106 to the center. The rope hole 118 in the portion where the upper rope 106 does not exist is completely closed to prevent the tool or parts from falling (for example, see Patent Document 1).

JP-A-9-194159

  In using the rope hole closing device 122 of the device of Patent Literature 1, it is necessary to accurately fit the position of the hoisting rope 106 and the notch portion 124a of the closing member 124. However, the position of the hoisting rope 106 with respect to the rope hole 118 tends to fluctuate arbitrarily. In general, when the elevator car 102 is suspended by a plurality of hoisting ropes 106, the elevator car 102 side is fixed at the center of the elevator car 102, but a linear arrangement is performed in consideration of the suspension balance. Absent. For example, in the case of three, the arrangement is fixed at the vertex position of the triangle. In the case of four, the arrangement is fixed at the corners of a quadrilateral or parallelogram. On the other hand, the pulley grooves of the sheave 112 are arranged in a horizontal row. As a result, when the elevator car 102 is far from the machine room 110, that is, when it is descending, the plurality of hoisting ropes 106 are arranged in a state close to a horizontal line according to the pulley groove arrangement of the sheave 112. On the other hand, when the elevator car 102 is close to the machine room 110, that is, when the elevator car 102 is raised, the plurality of hoisting ropes 106 follow the fixed state of the triangle or square on the elevator car 102 side with respect to the sheave 112. It moves from front to back and to the left and right from the state of one horizontal row. That is, the arrangement state of the hoisting rope 106 changes depending on the stop position of the elevator car 102 when the rope hole closing device 122 is used. As a result, depending on the position of the elevator car 102, there is a problem that the hoisting rope 106 and the notch portion 124a cannot be fitted properly. Since the hoisting rope 106 is given a large tension due to the weight of the elevator car 102 and the counterweight, it cannot be forcibly fitted by the sliding force of the closing member 124.

  In addition, a sponge or brush can be arranged at the tip of the closing member 124 to cope with the displacement of the hoisting rope 106. However, the sponge and the brush part can be easily deformed. Sufficient support strength could not be obtained, there was a risk of falling through a brush or sponge, and the function of preventing the fall could not be sufficiently achieved.

  Further, the rope hole closing device 122 of Patent Document 1 requires the opening / closing mechanism 126 and the like to be assembled in the machine room 110 at the time of work, and installed together with the position of the hoisting rope 106, and the work is complicated. Furthermore, the size of the rope hole 118 differs depending on the number of hoisting ropes 106 installed and the model of the elevator 100, and it is necessary to prepare a rope hole closing device corresponding to the size of the rope hole 118, and the management is complicated. The rope hole closing device composed of the closing member 124 and the opening / closing mechanism 126 has a problem that it is heavy and not very convenient to use.

  The present invention has been made in order to solve at least one of the problems as described above, and its purpose is to sufficiently close the rope hole without being influenced by the arrangement state or number of hoisting ropes, It is an object of the present invention to provide a rope hole closing device that can prevent a tool or a part from falling.

  It is another object of the present invention to provide a rope hole closing device that can easily cope with a change in the size of the rope hole and can sufficiently close the rope hole to prevent a tool or component from falling.

  It is another object of the present invention to provide a rope hole closing device that can be easily installed and handled at a work site.

  In order to solve the above-mentioned problem, the present invention has a wall portion of a predetermined height in a rope hole closing device that is formed in a floor of a machine room of an elevator and closes a rope hole that penetrates a hoisting rope. A frame that includes at least a surrounding region that encloses a region larger than the rope hole, and that includes an opening for receiving the hoisting rope inside the surrounding region in a part of the wall, and is disposed at a predetermined interval on the wall. A plurality of movable pins that can be pushed in substantially parallel to the floor surface of the machine room toward the opposite wall portion, and the movable pin is pushed toward the opposite wall portion so as to cross each movable pin. The rope hole is blocked in a portion where no rope exists.

  According to this configuration, the plurality of movable pins included in the frame body surrounding the area larger than the rope hole intersect with each other when pushed in, for example, to form a mesh surface. In this case, the movable pin that contacts the hoisting rope stops at that position, and the movable pin that does not contact advances toward the facing wall. As a result, the rope hole can be easily closed regardless of the position of the hoisting rope. Also, during installation, the movable pin can be easily installed without the need for accurate positioning or the like by simply pushing the movable pin toward the opposing wall portion, and easy to handle. Furthermore, since it is comprised only with a frame and a movable pin, weight reduction can be performed easily. In addition, it is preferable that the arrangement interval and the number of the movable pins are appropriately selected so that the mesh surface formed by the movable pins that intersect each other has a roughness enough to prevent the tools and parts from dropping. is there.

  Further, the present invention is characterized in that, in the above configuration, the wall portion forming the frame includes at least one joint portion that bends in a direction to close the enclosure region, and forms an enclosure region surrounding the rope hole. To do.

  According to this structure, the opening part which guides a hoisting rope to the inner side of an enclosure area | region can be closed easily, and the enclosure area | region completely closed can be formed. As a result, the movable pin can be arranged over the entire enclosing region, and the rope hole can be well closed.

  Moreover, the present invention is characterized in that, in the above configuration, the frame body forms a surrounding region surrounding the rope hole by connecting a plurality of piece-like wall portions by a plurality of joint portions.

  According to this configuration, by appropriately selecting the number of pieces connected to the piece-like wall portion, the enclosure region can be enlarged or reduced according to the size of the rope hole to which the rope hole closing device is applied. It can be satisfactorily closed with an optimally shaped rope hole closing device.

  Moreover, the present invention is such that, in the above configuration, the frame body is composed of four piece-shaped wall portions connected by three joint portions, and has a rectangular shape having connecting portions at both ends thereof. It is characterized by.

  According to this structure, it can respond to the rectangular rope hole which generally exists a lot. In addition, when not in use, the rectangular state can be flattened and flattened as needed, or the piece-like wall portion can be disassembled, making it easy to carry and store.

  In the above-described configuration, the present invention is characterized in that the movable pins that can be pushed in at least different directions are arranged in steps in the height direction of the wall portion.

  For example, when the frame body has a rectangular shape, the movable pins on the adjacent wall portions face in different directions. In this case, by disposing adjacent movable pins in steps, the movable pins can block the rope hole without interfering with each other.

  Further, the present invention is characterized in that, in the above configuration, the movable pin is magnetized.

  Here, all the movable pins may be magnetized, or may be selectively magnetized only at, for example, the upper stage when several intervals or indentation crosses.

  According to this configuration, even when a component smaller than the size of the mesh formed by the intersection of movable pins such as screws and bolts is dropped on the rope hole closing device, it can be satisfactorily captured and captured.

  Further, the present invention is characterized in that, in the above configuration, the movable pin is formed with a retaining portion at both ends.

  According to this configuration, the movable pin can be fixed easily, the structure can be simplified, and the handling becomes easy.

  Further, the present invention is characterized in that, in the above configuration, the joint portion has a lock portion for fixing a bent state.

  According to this configuration, the shape of the frame body can be easily maintained, and the rope hole can be reliably closed.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments (hereinafter referred to as embodiments) for carrying out the invention will be described with reference to the drawings.

  FIG. 1 is a schematic perspective view for explaining the external shape of the rope hole closing device 10 of the present embodiment. The rope hole closing device 10 according to the present embodiment is roughly divided into a frame body 12 arranged so as to surround a rope hole 118 (see FIG. 10) through which a plurality of hoisting ropes 106 having a diameter of, for example, φ12 mm are loosened, It is composed of a plurality of movable pins 14 which are arranged at predetermined intervals on the piece-like wall portion 12a constituting the frame body 12 and can be pushed into the opposed piece-like wall portion 12a substantially parallel to the floor surface 116 of the machine room 110. ing.

  The piece-shaped wall portion 12a that forms the frame body 12 is formed of a hard material (for example, metal, hard resin, or any other hard material) having a predetermined height, for example, about 10 cm. In the present embodiment, the frame body 12 has four piece-shaped walls connected by connecting the four piece-shaped wall portions 12a by the joint portions 16 formed of hinges or the like, and further connecting by the three joint portions 16. Both ends of the portion 12a are connected to each other by a connecting portion 18 including, for example, a hook 18a and an engagement ring 18b, thereby forming a closed enclosure region 20. In other words, by opening the connecting portion 18, an opening for receiving the hoisting rope 106 is formed with respect to the frame 12 forming the closed enclosure region 20.

  As is apparent from FIG. 1, in this embodiment, the movable pins 14 are crossed within the surrounding area 20 by pushing the movable pins 14 toward the opposing piece-like wall portions 12a (in the example of FIG. The rope hole 118 having a large opening is substantially blocked. At this time, the movable pin 14 that does not contact the hoisting rope 106 reaches the opposing piece-like wall portion 12a, and the movable pin 14 that contacts the hoisting rope 106 stops at that position. Therefore, the movable pin 14 pushed in from the four directions intersects so as to block the rope hole 118 while avoiding the hoisting rope 106.

  FIG. 2 shows a state in which the connection between the hook 18a and the engagement ring 18b is released and the rectangular shape of the frame 12 is broken. In FIG. 2, the hinge 16a of the joint portion 16 is partially visible. The movable pin 14 is sufficiently thin with respect to the thickness of the hoisting rope 106, for example, a round bar having a diameter of about 2 to 3 mm, and any material can be used as long as it is a hard material having a predetermined strength. For example, metal or resin rods can be used. Of course, the cross-sectional shape is arbitrary other than a circle, such as a rectangle or a triangle. This movable pin 14 is slidably inserted into an insertion hole formed in the piece-like wall portion 12a, and a retaining portion 14a is provided at both ends so as not to fall out of the insertion hole of the piece-like wall portion 12a. Is formed. The retaining portion 14a may be formed by connecting, for example, a ring-shaped member, a sphere, or a block-shaped member larger than the thickness of the movable pin 14 to the tip portion, or pushing the end portion of the movable pin 14 in. It may be formed by bending in a direction different from the direction.

  FIG. 3 shows an arrangement example of the movable pins 14 arranged on each piece-like wall portion 12a. For the sake of explanation, as shown in FIG. 3A, the piece-like wall portions 12a constituting the frame body 12 are sequentially denoted by reference numerals (1), (2), (3), and (4). 3 (b) to 3 (e) show a state where the connection at the connecting portion 18 of the frame body 12 is released, the joint portion 16 is extended, and the frame body 12 is expanded. The perspective view which shows the whole arrangement | positioning of the movable pin 14 at the time of assembling the frame 12 and seeing from the arrow A direction in Fig.3 (a) is shown. In the drawings used in the present embodiment, seven movable pins 14 are arranged on each piece-like wall portion 12a for simplification of illustration. However, although it depends on the size of the rope hole 118, more movable pins 14 are actually arranged on each piece-like wall portion 12a.

  As is apparent from each drawing, at least the adjacent piece-shaped wall portions 12a, for example, the movable pins 14 of (1) and (2) and the movable pins 14 of (2) and (3) are arranged so as not to interfere with each other. ing. For example, in the patterns shown in FIGS. 3B to 3D, the arrangement of the movable pins 14 in each piece-like wall portion 12a is linearly arranged at the same height in the height direction of the piece-like wall portion 12a. All the heights between the piece-like wall portions 12a are different. That is, all the movable pins 14 can be pushed toward the opposing piece-shaped wall portions 12a without interfering with each other. As a result, two sets of mesh surfaces are formed by four layers of movable pin groups. Of course, the movable pin 14 in contact with the hoisting rope 106 stops at the position of contact with the hoisting rope 106.

  Further, in the arrangement pattern of FIG. 3E, the movable pins 14 of the adjacent piece-like wall portions 12a do not interfere with each other as in (1) and (2) and (4) and (1), but (2 ) And (4), the opposing piece-like wall portions 12a are configured to face each other when they are pushed into each other at the same height. In the case of FIG. 3E, in (1) and (3), the movable pins 14 are arranged in a staggered manner, and the movable pins 14 facing each other do not collide when pushed. In this case, one set of mesh surfaces is substantially formed by the three-layer movable pin group. Of course, even in a staggered arrangement, the opposed movable pins 14 may be arranged at the same height so as to abut when pushed. Considering the essential function of the rope hole closing device 10 in the present embodiment, it is sufficient that one set of mesh surfaces is formed. For example, the arrangement of (1) and (3) in FIG. It is good also as a straight line pattern which collides like 2) and (4). In this case, the heights of (1) and (3) need to be changed from the heights of (2) and (4). Similarly, (1), (2), (3) and (4) may all be arranged in a staggered manner as long as the movable pins 14 of the adjacent piece-like wall portions 12a do not interfere with each other.

  Furthermore, in this embodiment, although the example which arrange | positions the movable pin 14 to all the piece-shaped wall parts 12a which form the frame 12 is shown, it is mutually by a group of at least 1 set of movable pins pushed in a different direction. It is sufficient to form intersecting mesh surfaces. For example, the movable pins 14 may be arranged only in (1) and (2) in FIG. Of course, if the mesh surface formed by the movable pins 14 is multi-layered, the rope hole 118 can be tightly closed, so that the function of preventing the tools and parts, particularly minute parts from falling, is improved. As is clear from the perspective views shown on the right side of FIGS. 3B and 3C, when forming a plurality of mesh surfaces, the mesh holes are arranged so that the positions of the mesh holes are shifted between the upper layer and the lower layer. As a result, the mesh becomes denser as a whole, and the fall prevention function is further improved. In addition, although it is preferable that the roughness of the mesh surface of an upper layer and a lower layer is the same, it does not necessarily need to be the same.

  Thus, by using a plurality of sufficiently thin movable pins 14 with respect to the thickness of the hoisting rope 106, a sufficiently fine mesh surface can be formed in a portion where the hoisting rope 106 does not exist. At that time, the movable pin 14 is brought into contact with the hoisting rope 106 and the pushing is stopped at that position, so that only the position of the hoisting rope 106 in the rope hole 118 is any position. Thus, it is possible to provide a rope hole closing device that forms a mesh surface while preventing the tool and parts from falling.

  By the way, the movable pin 14 is only inserted and arranged so as to be easily slidable with respect to the piece-like wall portion 12a. Therefore, the movable pin 14 is arbitrarily moved regardless of whether the rope hole closing device 10 is used or not used. In particular, when the movable pin 14 comes into contact with the hoisting rope 106 during use and stops in the middle of pushing (the state shown in FIG. 1), when the hoisting rope 106 swings back and forth, left and right, etc., the movable pin 14 is moved from the stop position. It may push back. In this case, the movable pin 14 is pushed back so that it does not exist, a missing hole larger than the mesh eye is generated, and there is a possibility that the tool or the part is dropped. Therefore, in the present embodiment, a fixing member that fixes the pushing position of the movable pin 14 to a predetermined position is provided. In the case of this embodiment, as shown in FIG. 4, for example, a stretchable belt (for example, a rubber belt) 22 is wound around the frame 12 as a fixing member. For example, the belt 22 has a start end fixed to a fixing portion 24 formed in a part of the piece-shaped wall portion 12a, and is sequentially passed through a belt guide 26 formed in a part of the other piece-shaped wall portion 12a. Go around 12 rounds. As shown in FIG. 5, a fixing hook 28 is formed at the rear end 22 a of the belt 22, and can be engaged with and fixed to fixing holes 30 formed in various portions of the belt 22. In the case of FIG. 5, the belt 22 is of a wide type so that all the movable pins 14 arranged in steps in each piece-like wall portion 12a can be prevented from being detached by one piece, but the piece-like wall portion 12a. A plurality of narrow belts may be used so that each movable pin 14 can be prevented from coming off.

  When the rope hole closing device 10 is not used, as shown in FIG. 4, all the movable pins 14 are pushed into the enclosed area 20 of the frame body 12, and if necessary, the belt 22 is applied with some tension. The belt 22 is mounted and stored in the rope hole closing device 10. In addition, by winding the belt 22 around the frame body 12 as shown in FIG. 4, the movable pin 14 is fixed at the position shown in FIG. 4, for example, the movable pin 14 moves during carrying or storage. It becomes easy to handle without.

  In addition, when the rope hole closing device 10 is not used, when the movable pin 14 is pushed to the completely opposed piece-like wall portion 12a as shown in FIG. A position holding means (for example, an engagement element or a magnet) may be formed on the pin 14 itself so as to maintain the fully pushed state. As shown in FIG. 3E, when the movable pins 14 facing each other face each other, if the engaging means is formed at least at one of the tip portions, the posture of the fully pushed-in movable pin 14 can be maintained. It can be carried out.

  On the other hand, when the rope hole closing device 10 is used, as described above, the movable pin 14 that abuts on the hoisting rope 106 stops at the abutment position as shown in FIG. 1 and protrudes toward the rear end side. At this time, the movable pin 14 moves due to the swing of the hoisting rope 106 or the like. Therefore, as shown in FIG. 6, the engagement position between the fixing hook 28 and the fixing hole 30 of the belt 22 is changed, and an urging force is applied so as to urge the protruding movable pin 14 to the hoisting rope 106. In this case, even when the hoisting rope 106 swings, the above-described missing hole is prevented from being generated without the contact between the hoisting rope 106 and the movable pin 14 being separated by the urging force due to the elasticity of the belt 22. . Since the movable pin 14 is urged by the hoisting rope 106, the rope hole closing device 10 can be fixed to the hoisting rope 106 using this urging force. In this case, the rope hole closing device 10 moves a little according to the swinging of the hoisting rope 106, but the enclosure region 20 of the frame body 12 may be sufficiently large with respect to the size of the rope hole 118. Of course, the rope hole closing device 10 may be fixed to the floor surface 116 of the machine room 110 by a fixing means such as a bolt. In this case, even if the movable pin 14 is pushed out in the direction opposite to the push-in direction due to the swinging of the hoisting rope 106, it is pushed in again by the urging force of the belt 22 as the swinging of the hoisting rope 106 stops. Thus, even when the hoisting rope 106 is swung by sliding the movable pin 14 so as to correspond to the wobbling of the hoisting rope 106, an excessive force does not act on the movable pin 14, and the hoisting rope 106 is swung. While maintaining the close contact between the upper rope 106 and the movable pin 14, it is possible to prevent inconvenience such as the movable pin 14 being bent or broken.

  By the way, when the rope hole 118 is closed while escaping the hoisting rope 106 by forming a mesh surface by crossing a plurality of movable pins 14 as in the present embodiment, a micro-equipment, for example, Screws may fall off. Therefore, in the present embodiment, the movable pin 14 is magnetized as shown in FIG. In FIG. 7 (a), the magnets are magnetized so that there are S and N poles at both ends, as in the case of a normal bar magnet. In FIG. 7B, an N pole is formed on one surface side of the cylindrical movable pin 14 and an S pole is formed on the other surface side. Similarly, in FIG. 7C, an N pole is formed on one surface side of the square movable pin 14 and an S pole is formed on the other surface side. In addition, although the intensity of magnetization is arbitrary, the extent which can adsorb | suck and hold | maintain the screw | thread and bolt which are micro components is preferable.

8A and 8B show an arrangement example when the movable pin 14 is magnetized. FIGS. 8A and 8B show the movable pin array in FIG. 3D as an example. When the movable pin 14 is magnetized, it is desirable that the S pole and the N pole are paired when the movable pin 14 is pushed toward the opposing piece-like wall portion 12a as shown in the figure. . In this case, as shown in FIG. 8 (c), when the movable pin 14 is pushed toward the opposing piece-like wall portion 12a, if the S poles and the N poles gather, a demagnetization phenomenon occurs, which is preferable. Absent.
7B, when the S and N poles are magnetized on the front and back surfaces of the cylindrical movable pin 14, it is desirable to arrange the S and N poles in pairs. In this case, by sandwiching the non-magnetized movable pin 14 that is pushed in different directions, the aggregation of the S poles and the N poles can be suppressed, and the above demagnetization phenomenon can be suppressed.

  As described above, by magnetizing the movable pin 14, even when a micropart such as a screw passes through the mesh surface formed by the movable pin 14 that intersects, the magnetic pin is attracted and dropped from the rope hole 118. Can be prevented satisfactorily.

  FIG. 9 shows an example of variations of the frame body 12. In the embodiment described above, as shown in FIG. 1, the frame portion 12 is formed by connecting the four piece-like wall portions 12 a by the joint portion 16 constituted by the hinge 16 a and the like. The frame body 12 is optional as long as it covers a range larger than the size of the rope hole 118 and can introduce the hoisting rope 106 into the surrounding region 20. For example, FIG. 9A shows a fixed frame 12 having an opening 32 in part. In this case, the hoisting rope 106 is received from the opening 32 into the enclosed area 20 inside the frame body 12. Although the movable pin 14 does not exist in the portion of the opening 32, the movable pin 14m is pushed toward the opening 32 from the opposing wall portion, and forms a mesh together with the movable pin 14n pushed in from the intersecting direction. The other portions form a two-layer mesh surface as in the example of FIG. As a result, the rope hole closing device 10 capable of sufficiently closing the rope hole 118 as a whole can be formed.

  FIG. 9B is an improved version of FIG. 9A and has a small piece-shaped wall portion 34 that closes the opening 32. In this case, the piece-shaped wall portion 34 may be opened / closed in parallel with the floor surface 116 of the machine room 110 by a hinge or the like, opened / closed in the vertical direction of the floor surface 116, or completely removable. In this case, the frame body 12 can be completely closed by the piece-shaped wall portion 34, and a mesh surface is formed by the movable pins 14 in the same manner as in the structure of FIG. be able to. 9A and 9B, the position where the opening 32 is formed is arbitrary.

  Further, FIG. 9C uses the piece-like wall portion 12a shown in FIG. 1 or the like only on one side of the frame 12, and the other portion uses the “substantially U-shaped” frame 12b. . The frame body 12 b and the piece-shaped wall portion 12 a are connected by a joint portion 16 such as a hinge as in FIG. 1 and can be opened and closed, and the hoisting rope 106 is introduced into the enclosure region 20. Further, after being introduced, the ends are joined by the connecting portion 18 to form a closed frame 12. The configuration of the movable pin 14 and the like is the same as that in the example of FIG. 1, and the same effect of closing the rope hole 118 can be obtained.

  On the other hand, FIG. 9D shows an example in which a large frame 12 is formed using a plurality of piece-like wall portions 12a as shown in FIG.

  The number of hoisting ropes 106 used and the fixing form of the hoisting ropes 106 on the elevator car 102 side vary depending on the scale of the elevator. Therefore, the size of the rope hole 118 also changes. At this time, it is inefficient to prepare the rope hole closing device 10 for each size of the rope hole 118. Therefore, in the present embodiment, a combination of a plurality of piece-like wall portions 12a is adapted to cope with a change in the size of the rope hole 118. That is, each piece-like wall portion 12a is detachable at the joint portion 16 portion connecting the piece-like wall portions 12a. FIG. 9D shows an example in which six piece-shaped wall portions 12a are connected. In this case, the pair of movable pins 14 in the left-right direction in the drawing are set to the same height, and the movable pins 14 that do not come into contact with the hoisting rope 106 abut each other at the central portion of the enclosure region 20. Of course, the length of the movable pin in the left-right direction may be increased to reach the opposing piece-shaped wall portion 12a.

  Further, the number of pieces connected to the piece-shaped wall portion 12a is arbitrary as long as the enclosed region 20 can be formed. In any case, a connecting portion 18 is formed in a part of the frame body 12 so that the hoisting rope 106 can be introduced into the inside of the enclosed region 20.

  Thus, the versatility of the rope hole closing device 10 can be improved by appropriately selecting the number of the piece-like wall portions 12 a and forming the frame body 12. As shown in FIG. 1 and FIG. 9D, when the frame body 12 is formed by combining a plurality of piece-like wall portions 12a, the rectangular state is collapsed and flattened as necessary when the rope hole closing device 10 is not used. Or the piece-like wall portion 12a can be individually disassembled, and it is easy to carry and store.

  By the way, when the frame body 12 is formed by connecting a plurality of piece-shaped wall portions 12a, the shape of the frame body 12 is maintained in the joint portion 16 that is the connection position, that is, the piece-shaped wall portion in the joint portion 16 is maintained. It is desirable to have a lock portion that fixes the bent state of 12a to a desired state (for example, an angle of 90 °). As the lock portion, for example, a fixing pin made of metal or the like that connects between adjacent piece-shaped wall portions 12a or a hinge 16a that constitutes the joint portion 16 may be provided with a lock mechanism. By providing the lock portion, the shape of the frame 12 is stabilized, and the handleability of the rope hole closing device 10 is improved. In addition, by providing the lock portion, the stability of the shape of the frame body 12 can be maintained against the urging force generated by the belt 22 even when the belt 22 is wound.

  The configuration of the rope hole closing device shown in FIG. 1 and FIG. 9 shown in the present embodiment is an example, and the hoisting rope is pushed by pushing the movable pin toward the opposing wall and intersecting each movable pin. The shape and form of the frame body, the shape and number of movable pins to be used, the arrangement form, etc. can be arbitrarily selected as long as the rope hole in the portion where no wire is present can be selected, and the same effect as this embodiment Can be obtained.
