Description

  The present invention relates to a wire rope gripping tool that is effective when towing or lifting a wire rope to a high place.

  Conventionally, when lifting and laying a wire rope such as a main rope of an elevator to a height inside an elevator tower, the wire rope is lifted by holding it with a rope clip or the like. However, since the holding area of the rope clip is extremely small and the wire rope is fastened in a linear shape, a concentrated clamping pressure is applied to the holding portion of the rope clip. The concentrated clamping pressure may cause the rope to be deformed, further damaged, and cut when a force is applied to the portion.

  In addition, since commercially available gripping tools such as camlers use the pulling force of the traction tool or the weight of the wire rope, the load may be instantaneously reduced due to the rising / lowering impact force of the winch or the like. When the load becomes light in this way, the rope may be unfixed and dropped, or the wire may be untwisted at the gripping portion and may come off the gripping portion. When it comes out of the gripping part, the rope falls off. When such a dropout occurs, if the wire rope is long (over 100 m), a heavy weight ranging from 100 kg to several tons will drop off. In order to prevent such dropping, a clamp for gripping a wire rope has been proposed in, for example, Japanese Patent Application Laid-Open No. 2001-271810 (Cited Document 1).

  The clamp according to this proposal has an outer clamp capable of gripping a wire rope having a predetermined diameter by tightening a pair of grips divided into two by bolts and nuts, and is divided into two divided inside the outer clamp. A wire rope having a diameter smaller than the wire rope having a predetermined diameter is gripped via the inner by including a pair of inner and fastening the outer clamp with the bolt and nut.

JP 2001-271810 A

  The clamp (gripping tool) described in Patent Document 1 enables a wire rope of various diameters to be gripped using a common outer clamp, and if this is used, damage to the wire rope due to gripping can be reduced. It is possible to hold the wire rope in a state where it is difficult to drop off while suppressing. However, this gripping tool is a dedicated gripping tool having a complicated structure, and the manufacturing cost is high and it cannot be used for general purposes.

  Therefore, the problem to be solved by the present invention is to provide a wire rope gripping tool that does not require expensive processing, is simple and inexpensive, suppresses damage to the wire rope, and can be used for general purposes. .

In order to solve the above problems, the present invention provides a wire rope gripping tool that grips a wire rope by pressing between two opposing members, and is curved so as to follow the outer periphery of the wire rope to be clamped. A curved pinching member having a length with respect to a direction that is 1/3 or more and 1/2 or less of the outer circumference of the wire rope, and having a length in the longitudinal direction that is equal to or greater than the diameter of the wire rope; A force to pinch the wire rope is applied in a state where the wire rope is arranged between the curved clamping members by facing the attached clamping plate and the two clamping plates to which the curved clamping member is attached. And a protective portion disposed between the wire rope and the curved clamping member when the wire rope is clamped by the curved clamping member. And a material.

  According to the present invention, it is possible to provide a wire rope gripping tool that does not require expensive processing, is simple and inexpensive, suppresses damage to the wire rope, and can be used for general purposes. Problems, configurations, and effects other than those described above will become apparent from the following description of embodiments.

It is a front view which shows the use condition of the wire rope holding tool which concerns on Example 2. FIG. It is a cross-sectional view of the wire rope gripping tool in FIG.

  The present invention is curved along the outer circumference of the wire rope to be pinched, and the length in the circumferential direction of the wire rope is 1/3 or more and 1/2 or less of the outer circumference of the wire rope to be pinched, and the length in the longitudinal direction is pinched. The wire rope is gripped using a curved pinching member having a diameter larger than that of the wire rope to be pressed. Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram illustrating an outline of an elevator apparatus to which the wire rope gripping tool according to the first embodiment is applied. As shown in the figure, in the elevator apparatus, a car 1 and a counterweight 4 are suspended by a wire rope which is an elevator main rope 7 in a hanging manner. The elevator main rope 7 enters the machine room 2 from above the car 1, and is wound around the sheave 3 of the hoisting machine and the baffle wheel and is connected to the upper part of the counterweight 4. When the hoisting machine operates, the sheep 3 rotates and the car 1 moves up and down along the guide rail 6 in the hoistway 5.

  At this time, if it becomes a high lift elevator, the load fluctuation | variation of the weight of this elevator main rope 7 will become large. That is, when the car 1 is lowered as the elevator moves up and down, the load on the car 1 side increases. Further, when the car 1 goes up, the load on the counterweight 4 side increases. As a result, the load fluctuation to the sheep 3 of the machine room 2 becomes excessive due to the movement of the weight. In order to prevent this load fluctuation, the elevator has a wire rope 8 that is weight-balanced with the elevator main rope 7 at the lower part of the car 1 and the lower part of the counterweight 4, and the elevator main rope 7 for the sheep 3 of the hoisting machine. The weight fluctuation is offset.

  However, since the elevator main rope 7 and the compensation wire rope 8 are both stranded wires, as the elevator moves up and down, the rope extends with time, and the gap 12 between the compensation pulley 9 and the floor of the pit 5a decreases. When the time further elapses, the gap 12 further decreases with the passage of time, and the compensator pulley 9 may come into contact with the floor surface of the elevator pit 5a. When the compensation pulley 9 comes into contact with the floor surface of the elevator pit 5a, the compensation wire rope 8 is loosened, and interference with other devices in the hoistway 5 is assumed, causing a problem.

  The elongation of this rope appears most during the elevator test run and adjustment immediately after the elevator is assembled and the test run is started, and then becomes relatively stable. Therefore, during the trial run and adjustment immediately after the start of the trial run, it is necessary to frequently adjust the length of the compensation wire rope 8 in order to maintain the gap 12. However, since the end of the Compen wire rope 8 is usually fixed and filled with a molten metal (lead alloy) in a dedicated rope socket, this multiple adjustment operation of the Compen wire rope 8 is very troublesome. It was inefficient work.

  Therefore, in the first embodiment, in this frequently occurring trimming adjustment work of the compensation wire rope 8, it is fixed to a dedicated rope socket without filling and fixing with molten metal. Specifically, one end of the compensation wire rope 8 is wrapped around the compensation wire suspension fitting 10 provided at the lower portion of the car 1, and the wire rope gripping tool 11 (hereinafter, also simply referred to as “gripping tool”) at the lower portion thereof. ) To grip the end. Thereby, the length adjustment of the compensation wire rope 8 can be easily performed.

  FIG. 2 is a front view showing a use state of the wire rope gripping tool in the first embodiment, and FIG. 3 is a cross-sectional view of the wire rope gripping tool in FIG. In these drawings, the wire rope gripping tool 11 includes a half steel pipe 15, a pinching plate 13, a protection and adjustment rubber 16, a bolt 14 and a nut 17.

  The half steel pipe 15 bends along the outer periphery of the compende wire rope 8 which is a wire rope to be pinched and functions as a curved pinching member. The half steel pipe 15 has a length in the circumferential direction of the wire rope that is 1/3 or more and 1/2 or less of the outer circumference of the companding wire rope 8 to be clamped, and a length in the longitudinal direction is equal to or more than the diameter of the compensating wire rope 8 to be clamped It is.

  The half steel pipe 15 is fixed to the opposing surfaces 13a of the pair of pinching plates 13 with the convex side facing the concave side that presses the rope inward. The two pinching plates 13 provided with the half steel pipes 15 are fixed by bolts 14 and nuts 17 with the concave surfaces of the half steel pipes 15 facing each other and with the compensation wire rope 8 sandwiched therebetween. At that time, the bolt 14 and the nut 17 function as a clamping pressure application member, and a clamping pressure for clamping the compensation wire rope 8 is applied by the tightening force of the both. The protection and adjustment rubber 16 is disposed between the compensation wire rope 8 and the half steel pipe 15 when the compensation wire rope 8 is sandwiched between the half steel pipes 15 and functions as a wire rope protection member.

  That is, the wire rope gripping tool 11 sandwiches the two compen- sion wire ropes 8 into the concave surface 15a on the inner side of the half-cut steel pipe 15 via the protective and adjusting rubber 16, and as shown in FIG. Tighten with bolts 14 and nuts 17 respectively. Thereby, the compensatory wire rope 8 can be gripped by being clamped with a predetermined clamping pressure below the compensator wire hanging bracket 10. The length of the rope is adjusted by loosening the fastening force between the bolt 14 and the nut 17, and after adjustment, if the bolt 14 and the nut 17 are tightened with a predetermined fastening force, the length can be easily fixed.

  4 is a front view of the pressure plate in FIGS. 2 and 3, and FIG. 5 is a cross-sectional view of the pressure plate in FIG. In the first embodiment, the thickness (diameter) of the wire to be clamped is assumed to be around 20 to 25 mm. And, when the diameter of the compensator wire rope 8 to be clamped and held is d, the clamping plate 13 has a width w of about 5 to 6 times its diameter, a length h of about 10 times its diameter, and a thickness t of It is comprised with the steel plate of about 10-20 mm. The pinching plate 13 is provided with bolt holes 19 of about 13φ at approximately two positions on the center line in the width direction.

  FIG. 6 is a diagram showing a processing procedure for a half steel pipe, and FIG. 7 is a cross-sectional view showing a state after the half steel pipe is processed. As shown in FIG. 6 and FIG. 7, the half steel pipe 15 in the first embodiment is a steel pipe 20 having a circular cross section that is about 2 mm larger than the diameter of the pinching gripping target wire having the maximum diameter assumed by the steel pipe inner diameter 20a. The cutting allowance 18 is taken and used in half. Specifically, the steel pipe cutting allowance 18 is set to 4 to 6 mm for the steel pipe 20 having an inner diameter of 27 mm, which is 2 mm larger than 25 mm which is the diameter of the pinching gripping wire rope having the maximum diameter assumed in the first embodiment. And cut into half-split steel pipes 15.

  FIG. 8 is a plan view showing a welded state between the pressing plate and the half steel pipe. The concave steel surface 15a of the half steel pipe 15 is formed on the face (opposing face) 13a on the opposite side of the clamping plate 13 shown in FIG. 4 with the half steel pipe 15 configured as described with reference to FIG. The convex wire rope 8 is disposed so as to face the convex wire rope 8, and the convex surface 15 b side is fixed to the facing surface 13 a by welding 22.

  In the first embodiment, the two pinching plates 13 provided with the half steel pipes 15 configured as described above are opposed to each other, and the compensator wire rope 8 is pinched and held in this state. At that time, the gripping force is a function of the pinching pressure applied to the compensatory wire rope 8.

  Therefore, when the pinching force is examined, it has been found that the following configuration is preferable in order to secure the gripping force of the compensator wire rope 8 by the gripper 11 while suppressing damage to the rope.

  That is, the width of the half steel pipe 15, in other words, the length corresponding to the circumferential direction of the compensation wire rope 8 is preferably 1/3 or more and 1/2 or less of the outer periphery of the compensation wire rope 8 to be clamped. If it is smaller than 1/3, the pinching width is narrow, the wire is easily deformed like a rope clip or the like, and the possibility of damaging the pinching wire is increased. On the other hand, when it is larger than 1/2, when the clamping plate 13 is tightened with the bolts 14 and the nuts 17 as the clamping pressure application members to apply the clamping pressure, the opposing ends of the half steel pipe 15 are opposed to each other. There is a possibility that the compensator wire rope 8 cannot be gripped with sufficient clamping pressure due to interference.

  Moreover, the length of the longitudinal direction of the half steel pipe 15 is good to be 3 times or more of the diameter of the compensation wire rope 8 to clamp. If the length in the longitudinal direction is smaller than the diameter of the compensation wire rope 8, a local clamping pressure like a rope clip is applied, and the compensation wire rope 8 is damaged. On the other hand, if it is 3 times or more, the possibility of damaging the Compen wire rope 8 due to pinching pressure can be greatly reduced. Therefore, in the first embodiment, as shown in FIGS. 2 and 4, the length of the half steel pipe 15 is set to be the same as the length of the pressing plate 13, that is, about 10 times the diameter d. Thereby, the damage to the compensation wire rope 8 due to the pinching pressure can be almost eliminated.

  Thus, the longer the length of the half steel pipe 15 is, the more the damage to the compensation wire rope 8 can be suppressed. However, if the length is too long, the handling becomes difficult. In addition, the weight increases, which affects the adjustment work. Therefore, the length of the half steel pipe 15 or the length in the longitudinal direction of the pressure plate 13 is preferably suppressed to 15 times or less the diameter of the wire rope to be clamped having the maximum diameter.

  In the first embodiment, when the compensator wire rope 8 is gripped by the half steel pipe 15, the protective and adjusting rubber 16 is inserted between the compensator wire rope 8 and the half steel pipe 15. In this embodiment, a rubber plate is used as the protective and adjusting rubber 16, but this rubber plate is a rubber plate made of natural rubber or synthetic rubber, or has elasticity and strength equivalent to this rubber plate. It is also possible to use an elastic member made of a synthetic resin.

  The protective and adjusting rubber 16 has a function of protecting the compen- sion wire rope 8 sandwiched between the half-cut steel pipes 15 and suppressing damage to the compen- sion wire rope 8. In addition to this, there is also a function of adjusting a gap so that a gap between the half steel pipe 15 and the compende wire rope 8 does not occur when the outer periphery of the compensator wire rope 8 and the half steel pipe 15 have different curvatures. Have.

  FIG. 9 is a cross-sectional view showing a gripping state of a large-diameter rope of the wire rope gripping tool according to the first embodiment, and FIG. 10 is a cross-sectional view showing a gripping state of a medium-diameter rope.

  The wire rope gripping tool 11 in the first embodiment is assumed to have a diameter of 20 to 25 mm as a target wire rope to be clamped and gripped as described above. Therefore, the half steel pipe 15 is set to 27 mm, which is about 2 mm larger than the diameter of the pinching gripping target wire having the maximum diameter assumed by the steel pipe inner diameter 20a. Therefore, if the compensation wire rope 8 is clamped without using the protective and adjusting rubber 16, the radius is different and the radius of curvature of the circumference is different, so that the outer circumference of the compensation wire rope 8 and the inner peripheral surface of the half steel pipe 15 are different. There is a gap between them.

  On the other hand, when the compensator wire rope 8a having a diameter of 25 mm is clamped as shown in FIG. 9, the protective and adjusting rubber 16a having a thickness of 1 mm is used, and the diameter of 20 mm is used as shown in FIG. When the compensator wire rope 8b is clamped, the protective and adjusting rubber 16b having a thickness of 3 mm is used. If the protection and adjustment rubbers 16a and 16b having different thicknesses are used in this way, even the compen- sion wire ropes 8a and 8b having different diameters can be held and held with no gap by the same wire rope gripping tool 11. . At this time, in the state shown in FIG. 9, the interval (tightening allowance) g of the half steel pipe 15 is 6 mm, and a sufficient fastening force can be obtained. Moreover, in the state shown in FIG. 10, the space | interval (tightening allowance) g of the half steel pipe 15 will be 5 mm, and a sufficient fastening force can also be obtained.

  With this configuration, the wire rope gripping tool 11 according to the first embodiment can grip and grip the compen- sion wire rope 8 having various diameters. Thereby, if the compensatory wire rope 8 of 16 to 25φ mainly used in the super high-rise elevator is prepared with the wire rope gripping tool 11 using the half steel pipe 15 having a slightly smaller steel pipe inner diameter 20a than the first embodiment, Two kinds of gripping tools can sufficiently satisfy the work requirements.

  Further, the wire rope gripping tool 11 according to the first embodiment is provided with two halved steel pipes 15 arranged on the pressure plate 13 so that their longitudinal directions are parallel to each other. Therefore, the length of the compensation wire rope 8 can be easily adjusted by wrapping the compensation wire rope 8 around the compensation wire suspension bracket 10 provided at the lower part of the car 1 and holding the end. it can. Moreover, the compensation wire rope 8 can be more reliably grasped by folding and grasping the compensation wire rope 8 in this way.

  Further, in addition to such a configuration, in the first embodiment, two bolt holes 19 are provided at a position between the two half steel pipes 15 of the pressure plate 13, and the half steel pipe 15 is provided with the bolt holes 19. The pinching force is applied by tightening the two pairs of bolts 14 inserted through the bolts and the nuts 17 screwed into the bolts 14. Therefore, the clamping pressure is equally applied to the two halved steel pipes 15, and the clamped compen- sed wire rope 8 can be reliably fixed.

  In addition, although the present Example demonstrates the example which clamps and grasps the compensatory wire rope 8 of an elevator, it cannot be overemphasized that not only the compensatory wire rope 8 but a simple wire rope can be pinched and grasped similarly. This example is shown in Example 2.

  In the first embodiment, the wire rope gripping tool 11 wraps one end of the compensation wire rope 8 around the compensation wire suspension bracket 10 provided at the lower portion of the car 1, and grips two wires at the lower portion. did. At that time, since the clamping pressure is obtained by the bolt 14 and the nut 17, the length can be adjusted easily and efficiently by loosening the bolt 14 and the nut 17 to adjust the length, and tightening again to apply the clamping pressure. Can be done.

  The feature of the wire rope gripping tool 11 shown in the first embodiment is that the thickness of the protective and adjusting rubber 16 is exchanged according to the difference between the wire diameter and the steel pipe inner diameter 20a even if the half-shaped steel pipe 15 having the same shape is used. By doing so, it is possible to pinch and grip a wire rope including the Compen wire rope 8 having various diameters.

  Therefore, not only is it used for gripping the two compensator wire ropes 8 as in the first embodiment, but also gripping the end of one wire rope as described in the above-mentioned Patent Document 1. Can also be used. In this case as well, as in the first embodiment, the present invention can be applied to the clamping pressure gripping of the wire rope 8 having various diameters.

  FIG. 11 is a front view showing a use state of the wire rope gripping tool according to the second embodiment, and FIG. 12 is a cross-sectional view of the wire rope gripping tool in FIG. In the following description, constituent elements that can be regarded as the same as or the same as those in the first embodiment are denoted by the same reference numerals, and redundant descriptions are omitted as appropriate.

  In the second embodiment, one half steel pipe 15 is attached to the central portion of the pressure plate 13 by welding 22 as in the first embodiment, and the concave surfaces 15a of the half steel pipe 15 are opposed to each other to sandwich the wire rope 8c. It comes to press. In this case, four bolt holes 19 are formed on the upper, lower, left, and right sides of the pressing plate 13, and the two pressing plates 13 are tightened with bolts 15 and nuts 17.

  Further, in the present embodiment, one of the pair of pressing plates 13 is largely taken and has a connection portion 24 provided with a connection hole 23 for attaching a shackle or connecting to a chain block. In the present embodiment, the connecting portion 24 is provided on one of the pair of pressing plates 13, but may be configured on both. By doing in this way, it is also possible to use the wire rope holding tool 11 as a tension tool.

  Also in the case of the second embodiment, the width of the half steel pipe 15 is set to 1/3 or more and 1/2 or less of the outer periphery of the wire rope 8c to be clamped. The length of the half steel pipe 15 in the longitudinal direction is not less than the diameter of the wire rope 8c to be clamped, preferably not less than 3 times, and more preferably not less than 10 times the diameter d. Thereby, the damage to the wire rope 8c by pinching pressure can be made into a substantially no state.

  By configuring in this way, even with one wire rope 8c, the wire rope 8c having various diameters can be clamped and held with one type of wire rope holding tool 11.

  Other parts that are not particularly described are configured in the same manner as in the first embodiment and function in the same manner, and thus description thereof is omitted.

  As described above, according to the present embodiment (Example 1 and Example 2), the following effects can be obtained.

1) In this embodiment, the wire rope gripping tool 11 that clamps and clamps the wire rope with two opposing members is bent along the outer periphery of the compensatory wire rope 8 (wire rope 8c) to be clamped, and the wire rope A half steel pipe 15 (curved pinching member) having a length in the circumferential direction of 1/3 or more and 1/2 or less of the outer circumference of the wire rope to be pinched and having a length in the longitudinal direction equal to or larger than the diameter of the wire rope 8 to be pinched. The pinch plate 13 provided with the half steel pipe 15 and the two pinch plates 13 provided with the half steel pipe 15 are opposed to each other, and the wire rope is sandwiched between the half steel pipes 15. When the wire rope is clamped between the half steel pipe 15 and the bolt 14 and the nut 17 (squeezing pressure imparting member) that apply the pressing force, the wire rope and the half steel pipe 1 It has a protective and adjusting rubber (protective member) 16, a configuration having a disposed between.

Because it was configured like this,
a. The wire rope can be gripped in a state in which damage to the wire rope due to gripping is suppressed and the wire rope is not easily dropped off.
b. In order to make it versatile and cheap to manufacture, a rubber plate is used to take a wide range of wire rope gripping portions (concave surface 15a of the half-cut steel pipe 15) and protect the wire and adjust the gap between the outer surface of the wire and the concave surface 15a. A protective and adjusting rubber 16 comprising: Further, the pinching pressure is obtained by tightening a strong bolt so that the wire does not fall off the gripper 11. As a result, it is possible to produce a simple structure and components that can be easily obtained in mass retailers and construction sites such as rubber plates, steel plates, and steel pipes. Therefore, it can be provided at a low price.
c. In some cases, the components can be obtained at the installation site or at the site where adjustments are made, and they can be manufactured and assembled using the common materials and tools at the site, which is extremely versatile.
d. Therefore, in this embodiment, it is possible to provide a simple, inexpensive, and versatile wire rope gripper that can handle various wire rope diameters without requiring expensive processing.
There are effects such as.

2) The length in the longitudinal direction of the half steel pipe 15 is not less than the diameter of the wire rope to be clamped, preferably more than three times, so that the possibility of damage to the wire rope due to the clamping pressure can be greatly reduced. it can. Furthermore, if it is about 10 times, it can be made into the state which does not almost damage the wire rope by pinching pressure.

3) The protection / adjustment rubber 16 corresponds to the difference in curvature between the outer circumference of the wire rope to be clamped and the concave surface 15a of the half steel pipe 15, and the outer circumference of the half steel pipe 15 (the concave surface 15a) and the wire rope (the outer circumference thereof). ) Is set to a thickness and elasticity that do not cause a gap between the protective rubber and the elastic rubber 16, so that the difference can be absorbed by the elastic deformation of the protective and adjusting rubber 16. As a result, the wire rope 8 having various diameters can be clamped and held with one type of holding tool 11.

4) Since the protective and adjusting rubber 16 is made of a rubber plate, it can be easily obtained and can be provided at low cost. Instead of the rubber plate of the protection / adjustment rubber 16, a protection / adjustment synthetic resin sheet or an elastic member may be used.

5) Two halved steel pipes 15 are arranged in parallel to the pinching plate 13 so that their longitudinal directions are parallel to each other, and the bolt holes 19 are positioned between the two halved steel pipes 15 of the pinching plate 13. Since the clamping force is obtained by inserting the bolts 14 into the bolt holes 19 and tightening them with the nuts 17, it is possible to easily and reliably fix the two compensatory wire ropes 8 below the compensating wire hanging bracket 10 at the same time. . At that time, if the fastening force between the bolts 14 and the nuts 17 is loosened, the length of the rope can be easily adjusted, and the working efficiency of adjusting the length of the compensation wire rope 8 can be improved. In this case, two wire ropes 8 having various diameters can be clamped and held simultaneously by one type of holding tool 11.

6) The half steel pipe 15 is arranged in the longitudinal direction of the pinching plate 13 at the center part of the pinching plate 13, and is bolted to the bolt holes 19 provided on both sides across the arrangement part of the half steel pipe 15 of the pinching plate 13. 14 is inserted and tightened with a nut 17 to obtain a clamping pressure.
