Description

  Embodiments of the present invention relate to a fixing jig used when a rope strand is fixed to a socket portion of a shackle rod.

  A main rope that suspends an elevator car or a counterweight on a hoistway has a plurality of strands twisted around a core rope at a predetermined pitch. One end of the main rope is fixed to the socket portion of the shackle rod.

  As an example of a method for fixing one end of the main rope to the socket part, after inserting a plurality of strands that have been untwisted into the mouth of the socket part, an alloy mainly composed of a low melting point metal is placed inside the socket part. A so-called Bavit type is known.

  When fixing one end of the main rope to the socket portion, if the main rope is drawn obliquely from the mouth of the socket portion with respect to the axis of the shackle rod, the alloy will move between the end portion of the main rope and the socket portion. The space between the inner surface and the inner surface is not evenly filled, and the bonding force is reduced.

  For this reason, conventionally, for example, the operator holds the shackle rod in an upright posture so that the mouth of the socket portion is directed downward by tying the upper portion of the shackle rod with a wire or the like to the beam at the work site. . Thereby, the main rope is kept in a state of being drawn straight out from the mouth of the socket portion downward.

Japanese Patent Laid-Open No. 10-167617

  As a result, the main rope may be pulled out obliquely from the socket part, and the soundness of the fixing part between the socket part and the main rope cannot be denied.

  The object of the present invention is to hold the shackle rod in a posture in which the rope is pulled straight down from the mouth of the socket part, and can improve the soundness of the fixing part between the socket part and the rope, The object is to obtain a fixing jig that contributes to improvement of workability.

  According to the embodiment, the shackle rod has a mouth into which a strand of rope is inserted, a cylindrical socket part in which the strand inserted into the mouth is fixed with a filler, and the socket part to the mouth. A rod portion extending toward the opposite side.

  A fixing jig used for fixing the shackle rod to the work site includes a frame, a rod support portion, and a rope fixing portion as main elements. The frame is erected from the installation surface of the work site. The rod support portion is provided at an upper portion of the frame and supports the rod portion in a vertically upright posture so that the mouth of the socket portion is directed downward. The rope fixing portion is provided on the frame, is positioned below the rod support portion, and fixes the rope in a state in which the rope is pulled straight out vertically from the mouth of the socket portion.

According to the present embodiment, the pair of guides 42a and 42b are fixed to the lower surface of the beam 40 by means such as welding. The guides 42a and 42b are examples of engaging portions, and are made of, for example, channel steel. The guides 42 a and 42 b protrude perpendicularly from the lower surfaces of both end portions of the beam 40, and are arranged in parallel with each other in the longitudinal direction of the beam 40.

  The guides 42a and 42b are detachably fitted into receiving ports 37 defined between the front surfaces of the support columns 16a and 16b and the protruding portions 36 of the brackets 35a and 35b. In a state where the guides 42a and 42b are fitted in the receiving port 37, the guides 42a and 42b are hooked on the protruding portions 36 of the brackets 35a and 35b. As a result, the lower surface of the beam 40 abuts against the protrusions 36 of the brackets 35a and 35b, and the beam 40 is bridged horizontally between the intermediate portions of the columns 16a and 16b.

  Since the pair of sandwiching tools 41a and 41b have a common configuration, one sandwiching tool 41a will be described as a representative, and the other sandwiching tool 41b will be denoted by the same reference numeral and description thereof will be omitted. .

  The holding tool 41a includes a support plate 44, a first block 45, and a second block 46 as main elements. As shown in FIGS. 4 and 5A, the support plate 44 has, for example, a flat square shape, and the rear end portion of the support plate 44 is overlaid on the upper surface of the beam 40.

  Further, a pair of bolt through holes 47 a and 47 b are formed at the rear end of the support plate 44. The bolt through holes 47 a and 47 b are long holes having an elongated opening shape extending in the longitudinal direction of the beam 40, and are arranged in a line at intervals in the longitudinal direction of the beam 40.

  A pair of first fixing bolts 48 a and 48 b are inserted into the bolt through holes 47 a and 47 b from above the support plate 44. The first fixing bolts 48 a and 48 b penetrate the beam 40 and are screwed into nuts 49 a and 49 b below the beam 40. By this screwing, the support plate 44 is fixed to the upper surface of the beam 40.

  Therefore, the position of the support plate 44 on the beam 40 can be adjusted along the longitudinal direction of the beam 40 by loosening the nuts 49 a and 49 b and releasing the tightening of the support plate 44.

  As shown in FIGS. 1 and 4, the support plate 44 includes a block holding portion 51 that projects horizontally toward the front of the beam 40. The block holding part 51 has a pair of bolt insertion holes 52 a and 52 b and a rope guide 53.

  The bolt insertion holes 52 a and 52 b are elongated holes having an elongated opening shape extending in a direction orthogonal to the beam 40, and are arranged in parallel with a gap in the longitudinal direction of the beam 40. Further, the bolt insertion holes 52 a and 52 b are opened at the front edge 51 a of the block holding portion 51.

  The rope guide 53 is an element that allows passage of the main rope 3 drawn from the mouth 6 of the socket portion 4, and is positioned between the bolt insertion holes 52 a and 52 b. The rope guide 53 has an elongated opening shape extending in a direction orthogonal to the beam 40 and is opened at the front edge 51 a of the block holding portion 51.

  The first block 45 and the second block 46 are square plate-like elements each having a predetermined thickness, and are made of, for example, an aluminum alloy. As shown in FIGS. 5A, 5B, and 5C, the first block 45 is abutted against the lower surface of the block holding portion 51 of the support plate 44 in a vertically installed posture, and a pair of second fixing bolts. It is fixed to the block holding part 51 via 55a, 55b and a pair of nuts 56a, 56b.

  The second fixing bolts 55a and 55b are inserted into the bolt insertion holes 52a and 52b from above the support plate 44, and pass through both end portions of the first block 45. The nuts 56a and 56b are screwed into the tip portions of the second fixing bolts 55a and 55b protruding from the lower surface of the first block 45. By this screwing, the first block 45 is fixed to the lower surface of the block holding portion 51 of the support plate 44.

  Therefore, the position of the first block 45 relative to the support plate 44 can be adjusted along the direction perpendicular to the longitudinal direction of the beam 40 by loosening the nuts 56a and 56b and releasing the tightening of the first block 45. It has become.

  The second block 46 is disposed behind the first block 45 in a vertical posture. The second block 46 is supported by the first block 45 via a pair of third fixing bolts 57a and 57b. The third fixing bolts 57 a and 57 b penetrate both end portions of the first block 45 from the front of the first block 45 and are screwed into screw holes 58 a and 58 b formed in the second block 46.

  Therefore, by adjusting the screwing amount of the third fixing bolts 57a and 57b into the screw holes 58a and 58b, the second block 46 approaches the first block 45 or moves away from the first block 45. It is designed to move linearly.

  As shown in FIGS. 5B and 5C, the first block 45 has a first surface 60 facing the second block 46. Similarly, the second block 46 has a second surface 61 facing the first block 45. The first surface 60 and the second surface 61 are erected vertically and face each other with a space therebetween.

  A first guide groove 62 is formed at the center of the first surface 60. Further, a second guide groove 63 is formed at the center of the second surface 61. The first guide groove 62 and the second guide groove 63 are curved in an arc shape so as to follow the curvature of the outer peripheral surface of the main rope 3 and are erected vertically. In addition, the first guide groove 62 and the second guide groove 63 face each other at a position corresponding to the rope guide 53 of the support plate 44 so as to sandwich the main rope 3.

  According to the fixing jig 1 of the present embodiment, the rope guide 53, the first guide groove 62, and the second guide groove 63 that each of the pair of holding tools 41a and 41b individually has are the rod receiver 32a of the rod support portion 18, It is located directly below 32b.

  Next, a series of work procedures until the shackle rod 2 is attached to the fixing jig 1 and one end portion of the main rope 3 is fixed to the socket portion 4 of the shackle rod 2 will be described.

  As shown in FIG. 2, the fixing jig 1 is divided into five parts: a base 15, a pair of support columns 16 a and 16 b, a pair of fall prevention legs 17 a and 17 b, a rod support portion 18, and a rope fixing portion 19. First, combine the five parts with each other at the work site.

  Specifically, the substrate 21 of the base 15 is placed on the installation surface G at the work site. Thereafter, the lower ends of the columns 16a and 16b are fitted into the guides 22a and 22b so as to cover the guides 22a and 22b erected from the substrate 21 from the outside. By this fitting, a frame 23 having a pair of support columns 16a and 16b erected vertically from the base 15 with a space therebetween is formed.

  At this time, it is desirable that the fall prevention legs 17a and 17b are previously fixed to the columns 16a and 16b with bolts 26 and nuts 27.

  Subsequently, the guides 33a and 33b of the rod support portion 18 are fitted into the upper ends of the columns 16a and 16b. As a result, the beam 30 of the rod support 18 is horizontally stretched between the upper ends of the columns 16a and 16b, and the upper ends of the columns 16a and 16b are connected to each other by the beam 30.

  Further, rod receivers 32a and 32b using single pipes are attached to clamps 31a and 31b fixed to the front surface of the beam 30. The rod receivers 32 a and 32 b are held in an upright posture with respect to the beam 30. The rod receivers 32a and 32b may be fixed to the beam 30 via the clamps 31a and 31b in advance before the guides 33a and 33b are fitted into the upper ends of the columns 16a and 16b.

  Thereafter, the guides 42a and 42b of the rope fixing portion 19 are fitted from above the brackets 35a and 35b into the receiving openings 37 provided in the intermediate portions of the support columns 16a and 16b, and the beam 40 of the rope fixing portion 19 is projected from the brackets 35a and 35b. It spans between the parts 36 horizontally. Thereby, a pair of clamping tool 41a, 41b is located directly under rod receptacle 32a, 32b, and the assembly operation of a series of fixing jig 1 is completed.

  Next, the operation shifts to the operation of attaching the shackle rod 2 to the fixing jig 1 one by one. At the time of attaching the shackle rod 2 to the fixing jig 1, one end portion of the main rope 3 is connected to the socket portion 4 of the shackle rod 2, and the main rope 3 is pulled out from the mouth 6 of the socket portion 4. .

  In the present embodiment, a procedure for attaching one shackle rod 2 to the fixing jig 1 will be described. First, the rod portion 5 of the shackle rod 2 is inserted into the rod receiver 32 a from below the rod support portion 18.

  At this time, of the first nut 10a and the second nut 10b screwed into the outer peripheral surface of the rod portion 5, the first nut 10a located on the upper end side of the rod portion 5 is removed from the rod portion 5 in advance. deep. As a result, the rod portion 5 is inserted into the rod receiver 32a until the second nut 10b hits the lower end of the rod receiver 32a.

  The first nut 10a is screwed into the upper end portion of the rod portion 5 protruding from the upper end of the rod receiver 32a after the rod portion 5 is inserted into the rod receiver 32a. The first nut 10 a adjusts the screwing position with respect to the rod portion 5 so that the socket portion 4 of the shackle rod 2 is positioned above the rope fixing portion 19.

  As a result, the rod receiver 32a is sandwiched in the axial direction between the first nut 10a and the second nut 10b, and the shackle rod 2 is temporarily fixed to the fixing jig 1. In a state where the shackle rod 2 is temporarily fixed to the fixing jig 1, the shackle rod 2 is held in a vertically standing posture, and the main rope 3 is drawn downward from the mouth 6 of the socket portion 4.

  Thereafter, the main rope 3 drawn from the mouth 6 is fixed to the rope fixing portion 19. At this time, the first block 45 and the second block 46 of the rope fixing portion 19 have been removed from the support plate 44 in advance, and only the support plate 44 remains on the beam 40. Therefore, first, the main rope 3 is guided from the front edge 51 a of the block holding portion 51 of the support plate 44 to the rope guide 53.

  Subsequently, the main rope 3 penetrating the rope guide 53 is interposed between the first guide groove 62 of the first block 45 and the second guide groove 63 of the second block 46. In this state, the first block 45 is fixed to the lower surface of the block holding portion 51 of the support plate 44 using the second fixing bolts 55a and 55b and the nuts 56a and 56b. Furthermore, the main rope 3 is sandwiched between the inner surface of the first guide groove 62 and the inner surface of the second guide groove 63 by tightening the third fixing bolts 57a and 57b.

  When the main rope 3 drawn downward from the socket portion 4 is loose when the main rope 3 is sandwiched between the inner surface of the first guide groove 62 and the inner surface of the second guide groove 63, the first rope The second nut 10b is rotated while the nut 10a is loosened, and the rod portion 5 is pulled up. Thereby, if the main rope 3 drawn out from the socket portion 4 extends in a straight line, the rod receiver 32a is sandwiched between the first nut 10a and the second nut 10b, and the rod portion with respect to the fixing jig 1 is inserted. The position of 5 is defined.

  Further, when the main rope 3 drawn downward from the socket part 4 is inclined obliquely with respect to the axis O1 of the rod part 5, the nuts 49a and 49b are loosened to move the support plate 44 in the longitudinal direction of the beam 40. . Furthermore, if necessary, the nuts 56a and 56b are loosened and the first block 45 is moved together with the second block 46 in a direction perpendicular to the beam 40, thereby adjusting the position of the holding tool 41a.

  As a result, a portion of the main rope 3 that is sandwiched between the first block 45 and the second block 46 is positioned coaxially with respect to the axis O1 of the rod portion 5. Thereafter, the clamping tool 41a is fixed to the beam 40 by tightening the nuts 49a, 49b and the nuts 56a, 56b, and the main rope 3 is straightly straight from the mouth 6 of the socket part 4 along the axis O1 of the rod part 5. Is held in the posture pulled out. Thus, the attachment work of the shackle rod 2 to the fixing jig 1 is completed.

  When the operation of attaching the shackle rod 2 to the fixing jig 1 is completed, the molten filler 65 is injected into the inside of the mouth 6 of the socket portion 4. As the filler 65, it is desirable to use an alloy mainly composed of a low melting point metal such as white metal. The filler 65 is filled into the mouth 6 through the opening 7 of the socket part 4 by the operator's manual work.

  As shown in FIG. 7, the filler 65 filled inside the mouth 6 flows between the inner surface of the mouth 6 and the strand 3 b and between the adjacent strands 3 b inside the mouth 6. Hardens with time. By hardening the filler 65, the strand 3 b and the socket portion 4 are integrally coupled, and one end portion of the main rope 3 is fixed to the shackle rod 2.

  According to the first embodiment, by attaching the shackle rod 2 to the fixing jig 1, the shackle rod 2 can be held in an upright posture so that the mouth 6 of the socket portion 4 is directed downward. . In addition, the main rope 3 connected to the socket part 4 was also drawn vertically straight from the mouth 6 of the socket part 4 downward while maintaining the coaxiality with the axis O1 of the rod part 5. Can be fixed to the state.

  For this reason, the positional relationship between the mouth 6 of the socket part 4 and the strand 3b of the main rope 3 expanded inside the mouth 6 is properly maintained, and between the adjacent strands 3b inside the mouth 6 and the mouth. It is possible to uniformly and uniformly fill the filler 65 between the inner surface 6 and the strand 3b.

  Therefore, the soundness of the fixing portion between the socket portion 4 and the main rope 3 is improved, and the quality of the shackle rod 2 to which the main rope 3 is coupled can be improved.

  Further, by using the dedicated fixing jig 1, for example, in a narrow dark place on the car or in a work site where no suitable beam for fixing the shackle rod 2 is found, the main rope can be connected to the mouth 6 of the socket portion 4. The one end of 3 can be securely fixed, which contributes to improvement in workability.

For this reason, for example, when the worker carries the fixing jig 1 to the work site, the fixing jig 1 does not become bulky, and the fixing jig 1 can be easily carried.

  In addition, since the five parts of the fixing jig 1 are assembled as a single structure by simple fitting, no troublesome work such as bolting is required. For this reason, there is an advantage that the fixing jig 1 can be easily assembled in a short time at the work site and contributes to improvement in workability.

[Second Embodiment]
8 and 9 disclose a second embodiment. In the second embodiment, the configuration of the shackle rod 100 attached to the fixing jig 1 is different from that of the first embodiment, and other configurations are the same as those of the first embodiment. Therefore, in the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 8, the shackle rod 100 of the second embodiment is a split type, and the socket portion 101 and the rod portion 102 are connected by a pin 103. The socket part 101 has a mouth 104 and a cylindrical part 105. The mouth 104 has a rope insertion opening 106 into which one end of the main rope 3 is inserted. The mouth 104 is formed in a conical shape in which the diameter gradually increases as the distance from the rope insertion opening 106 increases.

  The cylindrical portion 105 is coaxially connected to the end of the mouth 104 on the opposite side to the rope insertion port 106. The cylindrical portion 105 includes a straight tubular peripheral wall 107 and a rod insertion port 108 that opens toward the opposite side of the rope insertion port 106.

  A pair of slits 110 a and 110 b are formed in the peripheral wall 107 of the cylindrical portion 105. The slits 110 a and 110 b extend in a straight line in the axial direction of the cylindrical portion 105 and face each other in the radial direction of the cylindrical portion 105. Further, one end of each of the slits 110a and 110b is opened to the rod insertion port 108.

  A pair of connecting holes 111 a and 111 b are formed in the peripheral wall 107 of the cylindrical portion 105. The coupling holes 111a and 111b face each other in the radial direction of the cylindrical portion 105 between the slits 110a and 110b.

  The rod part 102 is comprised by the straight round bar. A flat head 113 is formed at one end of the rod 102. The head 113 is inserted into the slits 110 a and 110 b from the rod insertion port 108, and is positioned between the coupling holes 111 a and 111 b inside the cylindrical portion 105. For this reason, the head 113 divides the cylindrical portion 105 into two in the radial direction.

  The pin 103 is inserted across the connection holes 111 a and 111 b of the cylindrical portion 105. The pin 103 penetrates the head portion 113 of the rod portion 102 and is held by the socket portion 101 with a split pin 114.

  As shown in FIG. 9, the strand 3 b of the main rope 3 inserted from the rope insertion port 106 of the socket part 101 to the inside of the mouth 104 is coupled to the mouth 104 by a filler 65.

  In the divided shackle rod 100, the head portion 113 of the rod portion 102 is inserted into the rod insertion port 108 of the socket portion 101, and the cylindrical portion 105 is divided in the radial direction by the head portion 113. Therefore, in a state where the socket portion 101 and the rod portion 102 are connected by the pin 103, the opening area of the rod insertion port 108 is narrowed, and the filler 65 is filled from the rod insertion port 108 into the mouth 104. It becomes difficult.

  Therefore, in order to attach the divided shackle rod 100 to the fixing jig 1 disclosed in the first embodiment, the temporary fixing rod 115 shown in FIG. 9 is temporarily fixed to the socket portion 101 instead of the rod portion 102. To do.

  The arm portions 118a and 118b are arranged in parallel with a space therebetween, and the distal end portions of the arm portions 118a and 118b are removably supported by the cylindrical portion 105 via temporary fixing pins 120a and 120b, respectively. Yes. The temporary fixing pins 120a and 120b are detachably fitted in the connection holes 111a and 111b of the cylindrical portion 105. By this fitting, the clamping part 116 of the temporary fixing rod 115 is connected to the socket part 101.

  The shaft part 117 is coupled to an intermediate part of the connecting part 119 of the clamping part 116. The shaft portion 117 extends in a straight line toward the opposite side of the arm portions 118 a and 118 b, and the tip portion of the shaft portion 117 is held by the rod support portion 18 of the fixing jig 1.

  In a state where the shaft portion 117 of the temporary fixing rod 115 is fixed to the rod receiver 32a of the rod support portion 18, the shackle rod 100 is held by the fixing jig 1 in a vertically standing posture. Further, the socket portion 101 to which the temporary fixing rod 115 is connected is held in a posture in which the rope insertion port 106 is directed downward.

  Therefore, if the main rope 3 drawn downward from the rope insertion port 106 is fixed to the rope fixing portion 19 of the fixing jig 1 in the same procedure as in the first embodiment, the main rope 3 is connected to the socket portion 101. It is held in a state in which it is pulled out vertically from the mouth 104 in a straight line.

  According to the second embodiment, the sandwiching portion 116 of the temporary fixing rod 115 sandwiches the cylindrical portion 105 of the socket portion 101 from the radial direction between the pair of arm portions 118a and 118b. For this reason, the rod insertion port 108 of the cylindrical portion 105 is not blocked by the temporary fixing rod 115, and the rod insertion port 108 is exposed to the outside of the shackle rod 100 through between the arms 118 a and 118 b of the clamping portion 116. Yes.

  As a result, the filler 65 can be filled into the inside of the mouth 104 of the shackle rod 100 attached to the fixing jig 1 through the rope insertion port 106. Therefore, the fixing jig 1 can be similarly applied to the split shackle rod 100 by using the temporary fixing rod 115.

  In the second embodiment, after the filler 65 that couples the main rope 3 to the socket part 101 is cured, the temporary fixing rod 115 is removed from the socket part 101, and the regular rod part 102 is connected to the socket part 101 with the pin 103. To do. Thereby, the divided shackle rod 100 in which the main rope 3 is coupled to the socket portion 101 is obtained.
