Description

  The present invention relates to a roller guide that guides an elevator ride and a counterweight with rollers along guide rails.

  Each elevator is provided with a guide device for guiding the riding rod and the counterweight along the guide rail. The guide devices are installed in a total of four locations, two at the upper and lower portions with respect to the guide rails corresponding to the riding rod and the counterweight respectively. The guide device includes a roller-type guide device including three rollers that respectively come into contact with the blade of the guide rail from three directions as disclosed in Patent Document 1, and a guide rail as disclosed in Patent Document 2. There is a sliding type guide device provided with a guide shoe that comes into contact with the blade so as to surround three sides. The guide devices of Patent Literature 1 and Patent Literature 2 are provided with vibration-proof rubber in order to absorb vibration generated when moving along the guide rail.

  The guide device described in Patent Document 1 includes a support member that integrally supports three rollers. The support member has a flat plate portion that extends perpendicular to the direction of movement along the guide rail. The anti-vibration rubber is sandwiched in the direction (vertical direction) in which the rider moves between the flat plate portion and the eaves frame of the rider, and on the extension of the rotation surface of each roller that is in rolling contact with the guide rail Placed in position.

  The guide device described in Patent Document 2 has a mounting frame formed so as to surround the outer side of the guide shoe.

  The sliding type guide device described in Patent Document 2 has a small overall structure. However, when the loading load of the elevator board is large, the sliding type guide apparatus becomes a resistance when the carriage moves, so a roller type guide apparatus as described in Patent Document 1 is adopted. The At this time, if the anti-vibration rubber is attached in the direction as described in Patent Document 2, the anti-vibration rubber is disposed outside each roller, and thus the bulk of the guide device is increased.

  Further, the guide device receives a vibration and a load in a direction along the horizontal plane when passing through the connecting portion of the guide rail or due to a deviation in weight inside the riding rod. In the case of the guide device described in Patent Document 1, vibrations and loads applied to the guide device act in a shearing direction on the anti-vibration rubber. Further, in the case of the guide device described in Patent Document 2, each vibration-proof rubber is configured to actively cope with both compression / tensile deformation and shear deformation. In particular, a sliding guide device including a guide shoe as in Patent Document 2 also has a frictional force along the guide rail. Therefore, the anti-vibration rubber arranged as in Patent Document 2 always receives a load such as vibration in the shear direction along the direction in which the riding rod moves.

  When the anti-vibration rubber is subjected to a shear load, the joint surface with the fixed portion is likely to be peeled off or cracked along the direction of the shear load. Once delamination or cracking occurs, there is a possibility that the process up to rupture starting from this delamination or cracking may be accelerated by receiving a load in the compression / tensile direction. That is, the anti-vibration rubber is subjected to a shear load, so that the useful life as a consumable is shortened. However, when the anti-vibration rubber is designed based on the shear load, there is a concern that the vibration in the frequency band that leads to the generation of noise cannot be sufficiently attenuated when the load is applied in the compression direction.

  Therefore, the present invention provides an elevator guide device that has a small installation volume and is laid out so that a load is applied to the damper in the compression direction.

The guide device of the present invention guides the riding along guide rails laid in the elevator hoistway. The guide device includes a center roller, a side roller, a first idler, a second idler, a first supporter, a second supporter, a first damper, a second damper, With a damper. The center roller is in rolling contact with the tip surface of the guide rail blade. The side rollers are provided in a pair and are in rolling contact with the side surfaces on both sides of the blade of the guide rail. The first floating portion includes a first side wall that holds the center roller, and a first flange portion that is continuous with the first side wall and extends parallel to the tip end surface of the blade of the guide rail . The second floating portion includes a second side wall that holds the side roller, and a second flange portion that is formed continuously with the second side wall and extends parallel to the side surface of the teeth of the guide rail . The first support portion is fixed to the riding rod and arranged in parallel with the tip surface of the guide rail blade. The second support portion is fixed to the riding rod and arranged in parallel with the side surface of the blade of the guide rail. The first damper is sandwiched between the first floating portion and the first support portion, and receives and attenuates the vibration in the direction perpendicular to the tip surface of the blade of the guide rail as a compression load. The second damper is sandwiched between the second floating portion and the second support portion, and receives and attenuates the vibration in the thickness direction of the blade of the guide rail as a compressive load.

  In this case, since the dimensions of the guide rail blades do not change, in order to maintain the relative positions of the respective rollers, the first floating portion and the second floating portion are constituted by a continuous floating body. . The first damper is disposed in the vicinity of the portion of the floating body where the support shaft of the side roller is fixed, and the second damper is disposed in the vicinity of the portion of the floating body where the support shaft of the center roller is fixed. To do. Since the first floating portion and the second floating portion are configured in a row, even with such an arrangement, the vibration received by the center roller is received as a compression load by the first damper, and the roller receives again. The vibration can be received as a compressive load by the second damper.

  Furthermore, in this case, the first damper is disposed in a pair so as to sandwich the support shaft of the side roller in the extending direction of the guide rail, and the second damper is a position of sandwiching the supporting shaft of the center roller in the extending direction of the guide rail. Are arranged in a pair. By arranging the respective dampers in this way, the side roller is prevented from being twisted by the compressive load applied to the first damper, and the center roller is not subjected to the twisted stress by the compressive load applied to the second damper. To.

  Alternatively, the first damper may be disposed on the side opposite to the guide rail with respect to the center roller, and the second damper may be disposed on both sides of the rotation surface of the center roller. By disposing the damper in this way, it becomes easy to receive the vibration of the center roller that is likely to receive a large load.

  Alternatively, the second idler portion integrally holds the pair of side rollers, and the first idler portion and the second idler portion are provided independently of each other. The first dampers are arranged on both sides of the center roller rotating surface, and the second dampers are arranged in pairs at positions where the side rollers are interposed in the direction in which the guide rail extends. With this configuration, vibration applied to the center roller and the side roller is directly received as a compressive load by the first damper and the second damper, respectively. Further, since the first idler and the second idler are independent of each other, they are not affected by each other.

  Further, at this time, the first dampers are arranged in a pair sandwiching the support shaft of the center roller in the direction in which the guide rail extends. By doing so, the load applied to the center roller when the riding rod is tilted along the blade surface of the guide rail is distributed and received by the pair of first dampers. Prevents twisting force from being applied.

  Further, in order to improve the stability of the riding rod, the first damper applies a preload that urges the center roller in a direction in which the center roller is pressed against the tip surface of the guide rail blade.

  The guide device of the present invention receives and dampens vibration received by each of the rollers that are in rolling contact with the guide rail in the compression direction of the damper. Since the damper is arranged so that a compressive load is applied, when an anti-vibration rubber is used as the damper, it is easy to set the elastic coefficient and the natural vibration value, and it is also easy to design for aged deterioration. Further, by adopting a vibration-proof rubber that absorbs vibration in the audible area as a damper, noise that resonates inside the riding board due to vibration in the audible area can be reduced. In addition, since the vibration in the audible region is attenuated by the damper, a light-weight member that easily resonates with high-frequency vibration can be used as the member constituting the riding rod. As a result, the weight of the riding board can be reduced, which can contribute to resource saving and energy saving.

  Further, according to the invention in which the first idler and the second idler are constituted by a continuous idler, the relative position between the center roller and the side roller is established with respect to the blade of the guide rail, and the first The degree of freedom increases in the installation range in arranging the first damper and the second damper. When the first damper is disposed in the vicinity of the portion where the support shaft of the side roller of the floating body is fixed, and the first damper is disposed in the vicinity of the portion where the support shaft of the center roller of the floating body is fixed, the guide device As a result, the occupied volume can be reduced.

  According to the invention, the first damper is disposed at a position sandwiching the support shaft of the side roller in the extending direction of the guide rail, and the second damper is disposed at a position sandwiching the support shaft of the center roller in the extending direction of the guide rail. It is possible to prevent a torsional stress from being applied to the side roller by a compressive load applied to the first damper, and to prevent a torsional stress from being applied to the center roller by a compressive load applied to the second damper.

  According to the invention in which the first damper is disposed on the side opposite to the guide rail with respect to the center roller, and the second damper is disposed on both sides of the center roller rotating surface, vibration of the center roller to which a large load is easily applied is provided. It becomes easy to catch.

  Further, according to the invention in which the second idler portion integrally holds the pair of side rollers, and the first idler portion and the second idler portion are configured by separate separate members, the center roller and the side roller Are moved separately, and the first damper and the second damper respectively receive the load applied to the center roller and the side roller by vibration without being influenced by each other as a compression load. Furthermore, according to the invention in which the first damper is disposed in a pair with the support shaft of the center roller sandwiched in the direction in which the guide rail extends, the load applied to the center roller is distributed and received by the first damper disposed in the pair. Even when the riding rod is inclined along the blade surface of the guide rail, it is possible to prevent the twisting force from being applied to the first damper.

  Furthermore, according to the invention in which the preload for urging the center roller against the front end surface of the guide rail is applied by the first damper, the followability of the center roller with respect to the guide rail is improved. Stability during driving is improved and ride comfort is improved.

  In order to protect the first damper and the second damper when excessive vibration such as an earthquake is applied, a first locking piece and a second locking piece are further provided. The first locking piece is provided integrally with the first support portion, and has a first locking hole into which the support shaft of the center roller is inserted with a gap. The second locking piece is provided integrally with the second support portion, and has a second locking hole into which the support shaft of the side roller is inserted with a gap. The clearance between the support shaft of the center roller and the first locking hole and the clearance between the support shaft of the side roller and the second locking hole is smaller than the allowable amplitude of the first damper and the second damper.

Further, the second flange portion 112 b of the second floating portion 112 is the same portion as the first side wall 111 a of the first floating portion 111. As described above, the first idler 111 and the second idler 112 are integrally provided to form the inner bracket 1101 and support the center roller 11 and the pair of side rollers 12. Further, the inner bracket 1101 constitutes the floating body 110 provided integrally with the base plate 113 and the connecting piece 114.

  The base plate 113 extends along a plane perpendicular to the direction in which the guide rail 2 extends. The connecting piece 114 is mounted between the end portions of the second flange portion 112b opposite to the second side wall 112a of the second floating portion 112. The center roller 11 and the side roller 12 are held together by the floating body 110, so that the relative positions of the rollers are secured. Since the dimensions of the blade 21 of the guide rail 2 basically do not change, the relative position of the center roller 11 and the side roller 12 is ensured, so that the stability of the riding carriage 4 increases.

  The first support portion 121 is fixed to the upper beam 411 of the carriage 4 via the base plate 123 and is arranged in parallel with the tip surface 21 a of the blade 21 of the guide rail 2.

In the first embodiment, the first flange portion 111b and the second side wall 112a are the same. Therefore, the first damper 131 is a guide near the portion where the support shaft 12a of the side roller 12 held by the second side wall 112a is fixed, in this embodiment, as shown in FIGS. A pair is arranged at a position sandwiching the support shaft 12a of the side roller 12 in the direction in which the rail 2 extends. The first damper 131 receives and attenuates the vibration in the direction perpendicular to the tip surface 21a of the blade 21 of the guide rail 2 as a compression load. The first damper 131 is an anti-vibration rubber that attenuates vibrations in the audible sound frequency band.

  Further, since the first dampers 131 are arranged in a pair with the support shaft 12a of the side roller 12 sandwiched in the direction in which the guide rail 2 extends, the side surface of the blade 21 of the guide rail 2 is placed on the support shaft 12a of the side roller 12. It is possible to prevent torsional stress about an axis perpendicular to 21b. That is, it is possible to prevent the side roller 12 from meandering along the side surface 21b of the blade 21 of the guide rail 2 to generate new vibration or rotational resistance.

  As shown in FIGS. 4 and 5, the second damper 132 is disposed between the second flange portion 112 b of the second floating portion 112 and the second support portion 122. In the first embodiment, the second flange portion 112b and the first side wall 111a are the same. That is, the second damper 132 is a guide in the vicinity of the portion where the support shaft 11a of the center roller 11 held by the first side wall 111a is fixed, as shown in FIGS. 5 and 6 in this embodiment. A pair is arranged at a position sandwiching the support shaft 11a of the center roller 11 in the direction in which the rail 2 extends. The second damper 132 receives and attenuates the vibration in the direction perpendicular to the side surface 21b of the blade 21 of the guide rail 2 as a compression load. The second damper 132 is an anti-vibration rubber that attenuates vibrations in the audible sound frequency band.

  Further, since the second dampers 132 are arranged in a pair with the support shaft 11a of the center roller 11 sandwiched in the extending direction of the guide rail 2, the tip of the blade 21 of the guide rail 2 is placed on the support shaft 11a of the center roller 11.

  As shown in FIG. 4, in this embodiment, the center roller 11 is mounted in a screw hole provided in the first side wall 111a, and is cantilever supported by a washer 11b, a spring washer 11c, and a nut 11d. It is. Therefore, the second damper 132 disposed between the second flange portion 112b of the second floating portion 112 on the side not holding the support shaft 11a of the center roller 11 and the second support portion 122 is The second roller 132 disposed on the first side wall 111a of the first floating portion 111 on which the center roller 11 is supported is disposed at a mirror image position with the center roller 11 interposed therebetween. The center roller 11 extends over the second flange portion 112b of the second floating portion 112 that supports each of the pair of side rollers 12 that are arranged in a pair, so that the first roller 111 has a first side wall 111a. It may be provided so as to be held.

  As shown in FIGS. 4 and 6, the support shaft 11 a of the center roller 11 is inserted into the first locking hole 122 a provided in the second support portion 122 with a gap. Further, the support shaft 12 a of the side roller 12 is inserted into the second locking hole 121 a provided in the first support portion 121 with a gap. When the support shaft 11a and the first locking hole 122a of the center roller 11 and the support shaft 12a and the second locking hole 121a of the side roller 12 are both subjected to a large roll on the carriage 4 due to an earthquake or the like. By contacting each other, excessive shearing force is prevented from acting on the first damper 131 and the second damper 132.

  When the displacement in the shear direction applied to the first damper 131 exceeds the allowable amplitude, the support shaft 11a of the center roller 11 may be provided so as to interfere with the first locking hole 122a. Therefore, the first locking hole 122 a may be provided in the first locking piece independent of the second support portion 122. In this case, since the first locking piece regulates the displacement amount of the first damper 131, it may be fixed relatively to the first support part 121 that supports the center roller 11. Therefore, in this embodiment, the 2nd support part 122 provided integrally with the 1st support part 121 is equivalent to the 1st locking piece, and the 1st locking hole 122a is provided there.

  Similarly, when the displacement in the shearing direction applied to the second damper 132 exceeds the allowable amplitude, the support shaft 12a of the side roller 12 may be provided so as to interfere with the second locking hole 121a. Therefore, the second locking hole 121 a may be provided in the second locking piece independent of the first support portion 121. In this case, since the second locking piece regulates the amount of displacement of the second damper 132, it only needs to be fixed relatively to the second support portion 122 that supports the side roller 12. In this embodiment, the 1st support part 121 provided integrally with the 2nd support part 122 is equivalent to the 2nd locking piece, and the 2nd locking hole 121a is provided there.

A hole 112c is provided. The side roller 12 passes through the support shaft 12a through the long hole 112c, and is fixed by a nut 12c with a washer 12b sandwiched from the opposite side. By being comprised so that the distance between the side rollers 12 can be changed, it can apply also to the thing from which the dimension specification of the blade 21 of the guide rail 2 differs.

  An example of the assembly procedure of the guide device 10 according to the first embodiment configured as described above will be described below. As shown in FIG. 3, the guide device 10 is configured by assembling a floating body 110 to a support body 120 via a first damper 131 and a second damper 132. First, the male screws 133 of the first damper 131 and the second damper 132 are inserted into the mounting holes 120 a provided in various places of the support 120 and fixed with the nuts 135. Next, with respect to the support body 120 to which the first damper 131 and the second damper 132 are attached, the floating body 110 in which the center roller 11 and the side roller 12 are incorporated is connected to the distal end surface of the blade 21 of the guide rail 2. Mount along the direction perpendicular to 21a. Bolts 136 are tightened into the female screw holes 134 of the first damper 131 and the second damper 132 through the bolt holes 110 a of the floating body 110. The first damper 131 can be assembled even if it is first attached to the floating body 110 side.

  According to the guide device 10 of the first embodiment, vibration in a direction perpendicular to the distal end surface 21a of the blade 21 of the guide rail 2 is supported as a compressive load by the first damper 131, and the thickness of the blade 21 of the guide rail 2 is increased. The vibration in the direction is supported by the second damper 132 as a compressive load. The vibration generated between the guide rail 2 and the guide device 10 is shared and supported by the first damper 131 and the second damper 132 as loads in the compression direction, respectively, so that no shear load is applied. Therefore, when a synthetic resin material is used for each damper, the deterioration of the material due to the shear load is reduced, and the damping coefficient of the damper can be easily set.

  In the case of the guide device 10 according to the first embodiment, the first idler 111 and the second idler 112 are integrally configured as an idler 110. Accordingly, the first damper 131 is disposed in the vicinity of the support shaft 12a of the side roller 12, and the second damper 132 is disposed in the vicinity of the support shaft 11a of the center roller 11, thereby reducing the installation volume of the guide device 10. Can be suppressed. The contact area of the center roller 11 and the side roller 12 with respect to the guide rail 2 is small. If each roller is supported at a position opposite to the contact point with the guide rail, the direction in which the load applied to the center roller 11 and the side roller 12 acts when vibration occurs tends to be unstable. At this time, according to the guide device 10 of the present embodiment, the first damper 131 and the second damper 132 are each divided into a pair sandwiching the center roller 11 and the side roller 12 along the direction in which the guide rail 2 extends. Has been placed. By being arranged in this way, each of the first damper 131 and the second damper 132 can support the load applied to the center roller 11 and the side roller 12 equally as a compressive load.

  A guide device 10 according to a second embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 7 and 9, the guide device 10 is different in shape and arrangement of the first damper 131 and the second damper 132 from the guide device 10 of the first embodiment. Along with this, the structure and arrangement of the first support portion 121 are different. The configuration having the same function as that of the guide device 10 of the first embodiment will be described with reference to the description and drawings in the first embodiment, and the description will be given with the same reference numerals in FIGS. Omitted.

  In the guide device 10 according to the second embodiment, the first damper 131 is disposed on the side opposite to the guide rail 2 with respect to the center roller 11. The first floating portion 111 and the second floating portion 112 are integrally provided in the same manner as in the first embodiment, and constitute the floating body 110. The size of the center roller 11, the side roller 12, and the base plate 123 is the same as that in the first embodiment. Therefore, as can be seen from comparison in the drawings, the guide device 10 of the second embodiment is longer in the direction in which the guide rail 2 extends than the guide device 10 of the first embodiment. As shown in FIGS. 7 and 8, the floating body 110 has an end bridge 115 at the end of the first floating portion 111 and the second floating portion 112 apart from the base plate 123 in addition to the base plate 113.
