The present invention relates to an elevator apparatus in which vibration caused by deformation is reduced from being propagated to a building.

  In a normal elevator apparatus, as described in Japanese Patent Laid-Open No. 05-78055 (Patent Document 1), a passenger car and a counterweight are guided through a guide shoe along a guide rail erected in a hoistway. It is comprised so that.

  And when this car or counterweight travels, there is a phenomenon that the vibration or vibration of the car or counterweight propagates from the guide shoe to the guide rail and guide rail bracket and propagates to the building. There was a problem that noise and vibration were transmitted to the living room.

  As a method for solving this problem, the guide rail and the hoistway wall are conventionally connected to and fixed between the guide rail side bracket and the hoistway side bracket by a material such as rubber or urethane. Anti-vibration material is provided, the guide rail side bracket and hoistway side bracket, and the anti-vibration material are firmly connected with fixing bolts. It was like that. (This is explained in detail in FIG. 2 described later.)

JP 05-78055 A

  Prior to describing the present invention, first, the conventional technique and its problems will be described with reference to FIGS.

  FIG. 1 is a cross-sectional view for explaining the configuration of an elevator apparatus housed in a hoistway. Reference numeral 10 is a hoistway provided in a building, in which components constituting the elevator apparatus are housed. Has been.

  The elevator apparatus has a car 11 and a counterweight (not shown) and a hoisting machine 12 and a control panel (not shown in FIG. 1) as main components, and a pulley is attached to the lower part of the car 11 to provide a counterweight. A pulley is also attached, and a sheave is attached to the rotating shaft of the hoisting machine 12.

  Here, the hoisting machine 12 is configured to be attached to a beam fixed near the top of the hoistway 10, but is placed on the floor of a pit formed below the lowermost floor of the hoistway 10. May be.

  A beam is fixed to the upper part of the hoistway 10, and an intermediate pulley is attached to the beam, so that the winding direction of the main rope 13 is changed.

  One end of the main rope 13 is attached to the upper wall surface of the hoistway 10, and the hoistway starts from this end and passes through the pulley of the counterweight, the intermediate pulley, the sheave of the hoisting machine 12, the intermediate pulley and the pulley of the car 11. The other end is attached to the upper wall surface of 10.

  A shock absorber is provided at the lower end of the hoistway below the car 11 so as to buffer the shock caused by the collision of the car 11, and a buffer is provided at the lower end of the hoistway below the counterweight so as to buffer the shock caused by the collision of the counterweight. A vessel is installed.

  The above structure shows an example of the structure of the elevator device. In addition, there is no pulley in the car or counterweight, and it is arranged in a slidable manner via the hoisting machine 12 in the machine room above the hoistway. There are things that have been.

  The guide rail 14 is connected and fixed by a wall surface 15 of the hoistway 10 and a guide rail bracket 16. Therefore, the vibration of the guide rail 14 is transmitted to the wall surface 15 of the hoistway 10 through the rail bracket 16.

  In such an elevator apparatus, an operation command is given to an electric motor, a braking mechanism, and the like of the hoisting machine 12 by a control panel (not shown), and the car 11 moves up and down toward a predetermined level of the building by the operation command. Is.

  In this lifting / lowering operation, the car 11 and the counterweight are guided to the guide rail 14 by the guide shoe assembly 17. The guide shoe assembly 17 is guided when a guide shoe having lubricity slides on the guide rail 14, but vibration is transmitted to the guide rail 15 when the guide shoe and the guide rail 15 come into contact with each other.

  Therefore, the vibration and vibration of the car 11 and the counterweight are transmitted as vibrations to the guide rail 14 through the guide shoe, and the vibration of the guide rail 14 is transmitted to the wall surface 15 of the hoistway through the guide rail bracket 16. .

  As shown in FIG. 2, the guide rail side bracket 16A and the hoistway side bracket 16B used for connecting and fixing the guide rail 14 and the hoistway wall surface 15 as shown in FIG. An anti-vibration material 18 made of a material such as rubber or urethane is provided between the guide rail side bracket 16A, the hoistway side bracket 16B, and the anti-vibration material 18 with a fixing bolt 19, and the guide rail side bracket 16A is connected. The transmitted vibration is absorbed by the vibration isolator 18 so that the vibration is not transmitted to the hoistway side bracket 16B.

  In FIG. 2, the guide rail side bracket 16A and the hoistway side bracket 16B are provided with bolt insertion holes larger than the outer diameter of the threaded portion of the fixing bolt 19, and the vibration isolation between the guide rail side bracket 16A and the hoistway side bracket 16B is provided. An anti-vibration washer 21 is interposed between the guide rail side bracket 16A and the washer 20 of the fixing bolt 19, and a nut 22 is tightened to prevent vibration between the washer 20 and the hoistway side bracket 16B. The material 18 and the vibration proof washer 20 are firmly fixed. As described above, the guide rail side bracket 16 </ b> A and the hoistway side bracket 16 </ b> B are fixed by the tightening force between the fixing bolt 19 and the nut 22.

  However, when an emergency stop device (a device that decelerates and stops the car 11 by forcibly pressing the brakes against the guide rail 14 when the car 11 exceeds a predetermined lowering speed in the event of an abnormality) or due to an unbalanced load, etc. The vibration isolator 18 is damaged or deformed due to one or more causes such as when a large load is generated in the horizontal direction on the car 11 or when the vibration isolator 18 such as rubber or urethane deteriorates over time. 3, the fixing bolt 19 may be inclined and the guide rail 14 may be greatly displaced.

  That is, a gap of a predetermined dimension is always required between the outer diameter of the fixing bolt 19 and the inner diameter of the two bolt insertion holes through which the fixing bolt 19 formed in the guide rail side bracket 16A and the hoistway side bracket 16B passes. .

  When the vibration isolator 18 is deformed and the fixing bolt 19 cannot support the load acting between the guide rail side bracket 16 </ b> A and the hoistway side bracket 16 </ b> B and falls down, the two insertion holes and the fixing bolt 19 are used. The displacement of the guide rail side bracket 19 </ b> A increases due to the gap between them, resulting in a problem that the guide rail 14 is deformed.

  As described above, conventionally, a bolt insertion hole is provided in both the guide rail side bracket 16A and the hoistway side bracket 16B, and the nut 21 is tightened after the fixing bolt 19 having a predetermined gap is inserted into the bolt insertion hole. Thus, the vibration isolator 19 is sandwiched and fixed between the guide rail side bracket 16A and the hoistway side bracket 16B.

  The vibration isolator 18 may be permanently deformed (so-called sag phenomenon) due to aging or the like, or the vibration isolator 18 may be damaged when a large load is applied to the vibration isolator 18. When a large force such as the swing of the car 11 is applied to the guide rail 14 in a state where the vibration isolator 18 is damaged, the guide rail side bracket 16A receives a load applied to the guide rail 14. Become.

  If the vibration isolator 18 is damaged at that time, the support of the vibration isolator 18 is lost, and the fixing bolt 19 cannot receive the load. As shown in FIG. In the bolt insertion hole formed in the bracket 16A and the hoistway side bracket 16B, the guide rail 14 is greatly deformed in the horizontal direction.

  In this way, when the guide rail 14 is deformed, in a state where the car 11 is running, vibration due to this deformation is transmitted to the guide shoe sliding on the guide rail 14, and noise and vibration are applied to the car 11. Give passengers anxiety. In addition, the building also gives noise and vibration to the living room due to this vibration.

  An object of the present invention is to provide an elevator apparatus that prevents the guide rail from being deformed by suppressing the displacement of the guide rail side bracket even if the vibration isolator sandwiched between the guide rail side bracket and the hoistway side bracket is damaged. Is to provide.

  A feature of the present invention is that a vibration isolator is disposed between the hoistway side bracket and the guide rail side bracket, and the fixing bolt for fastening and fixing the hoistway side bracket and the antivibration material and the guide rail side bracket is fixed to the hoistway side bracket and the guide. It is fixedly attached to one side of the rail side bracket so that the displacement of the guide rail side bracket is prevented by a fixing bolt.

  According to the present invention, by fixing the fixing bolt to one of the brackets, even if the guide rail side bracket is displaced, the displacement is received by the fixing bolt, so that the deformation of the guide rail can be reduced. it can.

It is a block diagram which shows the structure of the conventional standard guide rail bracket part.

  Next, examples of the present invention will be described. Here, although a plurality of embodiments are proposed in the present invention, the same reference number indicates the same component or a component having a similar function.

  4 (a) and 4 (b), a fixing bolt 23 is fixedly planted by welding at a predetermined interval on the mounting end surface 16C of the hoistway side bracket 16B, and the fixing bolt 23 is located on the root side. A cylindrical portion 23A and a threaded portion 23B are formed from the middle toward the tip. A bolt insertion hole for a fixing bolt that has been conventionally provided is not formed on the mounting end surface 16C of the hoistway side bracket 16B.

  The vibration isolator 18 having an insertion hole 18A slightly larger than the diameter of the cylindrical portion 23A of the fixing bolt 23 is placed on the attachment end surface 16C of the hoistway side bracket 16B.

  Further, a mounting end face 16D is placed on the vibration isolator 18 through the insertion hole 16E of the guide rail side bracket 16A, and a convex shape protruding downward in the drawing having an anti-vibration function such as rubber or urethane. The anti-vibration washer 21 and the washer 20 are inserted into the fixing bolt 23 and are tightened and fixed in cooperation with the nut 22.

The convex vibration washer 21 has a large diameter portion and a small diameter portion. The large diameter portion is placed on the upper surface of the guide rail side bracket 16A and has a vibration isolating function with the washer 20. The small diameter portion is a guide. Positioned between the insertion hole 16E of the rail side bracket 16A and the fixing bolt 23, the anti-vibration function between the insertion hole 16E and the fixing bolt 23 and the direct contact between the fixing bolt 23 and the insertion hole 16E are buffered to each other. It has a function to prevent damage. (Hereinafter referred to as an anti-vibration washer including other embodiments, the functions thereof are equivalent.)
The insertion hole 16E of the guide rail side bracket 16A also has an inner diameter that is slightly larger than the outer diameter of the cylindrical portion 23A of the fixing bolt 23, and a small-diameter portion of the anti-vibration washer 21 is interposed therebetween.

  When the nut 22 is attached to the fixing bolt 23 and tightened, the pressing force (tightening force) generated by the nut 23 is transmitted to the mounting end surface 16D of the guide rail side bracket 16A via the washer 20 and the vibration isolating washer 21, and finally. Can compress the vibration isolator 18 by a predetermined compression allowance to firmly fix the guide rail side bracket 16A and the hoistway side bracket 16B.

  Here, the length t1 of the cylindrical portion 23A of the fixing bolt 23 is determined to be longer than the length obtained by adding the thickness t2 of the vibration isolator 18 and the thickness t3 of the mounting end surface 16D of the guide rail side bracket 16 to the nut. At the time of tightening and fixing by 22, the insertion hole 16 </ b> E of the guide rail side bracket 16 </ b> A and the insertion hole 18 </ b> A of the vibration isolator 18 are positioned at the cylindrical portion 23 </ b> A portion of the fixing bolt 23. This is expected to prevent the threaded portion 23B of the fixing bolt 23 from being damaged.

  However, when the fixing bolt 23 is not used again by repair or inspection, or the screw portion 23 can be damaged, or when the screw portion 23B is protected by the small diameter portion of the vibration washer 21, The insertion hole 16E of the guide rail side bracket 16A and the insertion hole 18A of the vibration isolator 18 do not necessarily have to be positioned in the cylindrical portion 23A portion.

  Therefore, when using a fixing bolt in which the cylindrical portion 23 is omitted or a fixing bolt in which the cylindrical portion 23A is shortened, the insertion hole 16E of the guide rail side bracket 16A and the insertion hole 18A of the vibration isolating material 18 are the screw portion 23B and the screw portion. Even if it exists in the position straddling 23B and cylindrical part 23A, it does not interfere.

  The nut 22 uses a double nut to improve the loosening prevention effect, and is transmitted from the mounting end face 16D of the guide rail side bracket 16A via the fixing bolt 23 using the vibration-proof washer 21 as described above. Reduces vibration propagation.

  In the above, even if the guide rail 14 is displaced with the vibration isolator 18 damaged as shown in FIG. 4C, the fixing bolt 23 is attached to the hoistway side bracket 16B by means such as welding. The function of the stopper is that the insertion hole 16E provided in the mounting end surface 16D of the guide rail side bracket 16A is prevented from moving by the cylindrical portion 23A of the fixing bolt 23 or the screw portion 23B. The displacement of the guide rail 14 is at least the difference between the outer diameter of the cylindrical portion 23A or the screw portion 23B of the fixing bolt 23 and the inner diameter of the insertion hole 16E formed in the mounting end surface 16D of the guide rail side bracket 16A. Can be suppressed. In addition, when the thickness of the small-diameter portion of the vibration-proof washer 21 is taken into consideration, the difference is further reduced.

  Therefore, the inner diameter of the insertion hole 16E formed in the mounting end surface 16D of the guide rail side bracket 16A is made slightly larger than the outer diameter of the cylindrical portion 23A or the screw portion 23B of the fixing bolt 23, for example, the insertion hole 16E and the fixing bolt 23 If the dimension is set such that the cylindrical portion 23A or the screw portion 23B and the small diameter portion of the vibration washer 21 are substantially in contact with each other, the displacement of the guide rail 14 can be minimized.

  As described above, according to this embodiment, since the displacement of the guide rail can be suppressed, the vibration caused by the deformation is transmitted to the guide shoe that slides on the guide rail while the car is running, which is caused by the deformation of the guide rail. Therefore, it is possible to solve problems such as giving noise and vibration to the car and giving anxiety to the passengers and also giving noise and vibration to the room of the building by this vibration.

  In the present embodiment, the fixing bolt 23 is fixedly planted on the hoistway side bracket, but it goes without saying that the fixing bolt 23 may be fixedly planted on the guide rail side bracket.

  Next, a second embodiment of the present invention will be described with reference to FIG. The same reference numerals as those in the embodiment shown in FIG. 4 indicate the same components or components having similar functions.

  5 (a) and 5 (b), a fixing bolt 24 is planted by welding at a predetermined interval on the mounting end face 16C of the hoistway side bracket 16B, and the fixing bolt 24 has a cylindrical portion 24A on the base side. And the thread part 24B is formed toward the front-end | tip from the middle.

  The outer shape of the cylindrical portion 24A is formed larger than the outer shape of the screw portion 24B, the cylindrical portion 24A has a stopper function described later, and the screw portion 24B has a tightening function. Thus, by increasing the outer diameter of the cylindrical portion 24A, it is possible to increase the strength against the load from the guide rail side bracket 16A. Moreover, by producing the height of this part accurately, it can be tightened without considering the amount of compression of the vibration isolator 18 at the time of installation, and improvement in workability can be expected.

  A vibration isolator 18 having an insertion hole 18A slightly larger than the diameter of the cylindrical portion 24A of the fixing bolt 24 is placed on the attachment end surface 16C of the hoistway side bracket 16B.

  Further, the mounting end face 16D is placed on the vibration isolator 18 through the insertion hole 16E of the guide rail side bracket 16A, and the anti-vibration washer 21 and the washer 20 are inserted into the fixing bolt 24 and tightened with the nut 22 to be fixed. It has come to be. The insertion hole 16E of the guide rail side bracket 16A also has an inner diameter that is slightly larger than the outer diameter of the cylindrical portion 24A of the fixing bolt 23, and a small-diameter portion of the anti-vibration washer 21 is interposed therebetween.

  When the nut 22 is attached to the fixing bolt 24 and tightened, the pressing force (tightening force) generated by the nut 22 is transmitted to the mounting end surface 16D of the guide rail side bracket 16A via the washer 20 and the vibration isolating washer 21, and finally. Can compress the vibration isolator 18 by a predetermined compression allowance to firmly fix the guide rail side bracket 16A and the hoistway side bracket 16B.

  Here, the length t1 of the cylindrical portion 24A of the fixing bolt 24 is determined to be longer than the sum of the thickness t2 of the vibration isolator 18 and the thickness t3 of the mounting end surface 16D of the guide rail side bracket 16. When the nut 22 is tightened and fixed, the insertion hole 16E of the guide rail side bracket 16A and the insertion hole 18A of the vibration isolator 18 are positioned at the cylindrical portion 24A portion of the fixing bolt 24.

  In the above, even if the guide rail 14 is displaced with the vibration isolator 18 damaged, the fixing bolt 24 is fixedly planted on the hoistway side bracket 16B by means such as welding, and the guide rail. The insertion hole 16E provided in the mounting end surface 16D of the side bracket 16A is prevented from moving by the cylindrical portion 24A of the fixing bolt 24, and thus has a stopper function. The displacement of the guide rail 14 is at least the fixing bolt 24. The difference between the outer diameter of the cylindrical portion 24A and the inner diameter of the insertion hole 16E formed in the mounting end surface 16D of the guide rail side bracket 16A can be suppressed. In addition, when the thickness of the small-diameter portion of the vibration-proof washer 21 is taken into consideration, the difference is further reduced.

  Therefore, the inner diameter of the insertion hole 16E formed in the mounting end surface 16D of the guide rail side bracket 16A is made slightly larger than the outer diameter of the cylindrical portion 24A of the fixing bolt 24, for example, the circular column 24A of the insertion hole 16E and the fixing bolt 24. If the dimension is set so that the small diameter portion of the vibration washer 21 substantially contacts, the displacement of the guide rail 14 can be minimized.

  As described above, according to this embodiment, since the displacement of the guide rail can be suppressed, the vibration caused by the deformation is transmitted to the guide shoe that slides on the guide rail while the car is running, which is caused by the deformation of the guide rail. Therefore, it is possible to solve problems such as giving noise and vibration to the car and giving anxiety to the passengers and also giving noise and vibration to the room of the building by this vibration.

  In the present embodiment, the fixing bolt 24 is fixedly planted on the hoistway side bracket, but it goes without saying that the fixing bolt 24 may be fixedly planted on the guide rail side bracket.

  Next, a third embodiment of the present invention will be described with reference to FIG. The same reference numerals as those in the embodiment shown in FIG. 4 indicate the same components or components having similar functions.

  6 (a) and 6 (b), a cylindrical portion 25 is fixedly planted by welding at a predetermined interval on the mounting end surface 16C of the hoistway side bracket 16B, and this cylindrical portion 25 is internally screwed. A hole 27 is provided. The column part 25 has a stopper function to be described later.

  A vibration isolator 18 having an insertion hole 18A having an inner diameter slightly larger than the outer diameter of the cylindrical portion 25 is placed on the mounting end surface 16C of the hoistway side bracket 16B.

  Further, the mounting end face 16D is placed on the vibration isolator 18 through the insertion hole 16E of the guide rail side bracket 16A, and the vibration isolator washer 21 and the washer 20 are inserted into the fixing bolt 26 on the mounting end face 16D. The hole 27 is fastened and fixed. The insertion hole 16E of the guide rail side bracket 16A also has an inner diameter that is slightly larger than the outer diameter of the cylindrical portion 25, and a small diameter portion of the anti-vibration washer 21 is interposed therebetween.

  When the fixing bolt 26 is attached to the screw hole 27 of the cylindrical portion 25 and tightened, the pressing force (tightening force) generated by the fixing bolt 26 is applied to the mounting end face 16D of the guide rail side bracket 16A via the washer 20 and the vibration isolator washer 21. As a result, finally, the guide rail side bracket 16A and the hoistway side bracket 16B can be firmly fixed by compressing the vibration isolator 18 by a predetermined compression allowance.

  Here, the length t1 of the cylindrical portion 25 is determined to be longer than the length obtained by adding the thickness t2 of the vibration isolator 18 and the thickness t3 of the mounting end surface 16D of the guide rail side bracket 16. At the time of tightening and fixing, the insertion hole 16E of the guide rail side bracket 16A and the insertion hole 18A of the vibration isolator 18 are positioned at the cylindrical portion 25 portion.

  In the above, even when the guide rail 14 is displaced in a state where the vibration isolator 18 is damaged, the cylindrical portion 25 is fixedly planted on the hoistway side bracket 16B by means such as welding, and the guide rail. The insertion hole 16E provided in the mounting end surface 16D of the side bracket 16A has a function of a stopper because its movement is blocked by the peripheral surface of the cylindrical portion 25, and the displacement of the guide rail 14 is at least of the circular portion 25. The difference between the outer diameter and the inner diameter of the insertion hole 16E formed in the mounting end surface 16D of the guide rail side bracket 16A can be suppressed. In addition, when the thickness of the small-diameter portion of the vibration-proof washer 21 is taken into consideration, the difference is further reduced.

  Therefore, the inner diameter of the insertion hole 16E formed in the mounting end surface 16D of the guide rail side bracket 16A is made slightly larger than the outer diameter of the cylindrical portion 25, for example, the insertion hole 16E, the circular column 25 of the fixing bolt 24, and the vibration washer. If the dimension is set such that the small diameter portion 21 substantially contacts, the displacement of the guide rail 14 can be minimized.

  As described above, according to this embodiment, since the displacement of the guide rail can be suppressed, the vibration caused by the deformation is transmitted to the guide shoe that slides on the guide rail while the car is running, which is caused by the deformation of the guide rail. Therefore, it is possible to solve problems such as giving noise and vibration to the car and giving anxiety to the passengers and also giving noise and vibration to the room of the building by this vibration.

  In this embodiment, the cylindrical portion 25 is fixedly planted on the hoistway side bracket, but it goes without saying that the cylindrical portion 25 may be fixedly planted on the guide rail side bracket.

  Next, a fourth embodiment of the present invention will be described with reference to FIG. The same reference numerals as those in the embodiment shown in FIG. 4 indicate the same components or components having similar functions.

  7 (a) and 7 (b), screw holes 28 are directly formed on the attachment end surface 16C of the hoistway side bracket 16B at a predetermined interval. A screw portion 29B of a fixing bolt 29 is screwed into the screw hole 28, and the fixing bolt 29 has a structure in which the screw portion 29B and the screw hole 28 are fixedly planted.

  The vibration isolator 18 is placed on the mounting end surface 16C of the hoistway side bracket 16B, and the mounting end surface 16D is placed on the anti-vibration material 18 through the insertion hole 16E of the guide rail side bracket 16A. The washer 21 and the washer 20 are inserted into a fixing bolt 29 and fastened with a nut 22 to be fixed.

  When the fixing bolt 29 is screwed into the screw hole 28 formed in the attachment end surface 16C of the hoistway side bracket 16B, and the nut 22 is further attached and tightened, the pressing force generated by the nut 22, the screw hole 28 of the attachment end surface 16C and the fixing bolt 29 ( (Tightening force) is transmitted to the mounting end face 16D of the guide rail side bracket 16A via the washer 20 and the vibration isolator washer 21, and finally the vibration isolator 18 is compressed by a predetermined compression allowance to be connected to the guide rail side bracket 16A. The hoistway side bracket 16B can be firmly fixed.

  Here, a cylindrical portion 29A is formed on the base side of the fixing bolt 29, and the length t1 of the cylindrical portion 29A is a length that extends to the region of the vibration isolator 18 when the fixing bolt 29 is fixed in a normal state. It is decided.

  Therefore, at the time of fastening and fixing with the nut 22, at least the insertion hole 16 </ b> E of the guide rail side bracket 16 </ b> A is positioned at the cylindrical portion 29 </ b> A portion of the fixing bolt 29. This is expected to prevent damage to the threaded portion 29B of the fixing bolt 29 as described above.

  However, when the fixing bolt 23 is not used again by repair or inspection, or the screw portion 23 may be damaged, or when the screw portion 29B is protected by the small-diameter portion of the anti-vibration washer 21, etc. The insertion hole 16E of the guide rail side bracket 16A and the insertion hole 18A of the vibration isolator 18 do not necessarily have to be positioned in the cylindrical portion 29A.

  Therefore, when using a fixing bolt in which the cylindrical portion 29A is omitted or a fixing bolt in which the cylindrical portion 29A is shortened, the insertion hole 16E of the guide rail side bracket 16A and the insertion hole 18A of the vibration isolator 18 are the screw portion 29B portion, or It may be present at a position straddling the threaded portion 29B and the cylindrical portion 29A.

  In this case, the small-diameter portion of the vibration-proof washer 21 is located between the insertion hole 16E of the guide rail side bracket 16A and the screw portion 29B of the fixing bolt 29, or the portion straddling the screw portion 29B and the cylindrical portion 29A. And the screw portion 29B, and a function of buffering direct contact between the screw portion 29B and the insertion hole 16E to prevent mutual damage.

  In the above, even if the guide rail 14 is displaced in a state where the vibration isolator 18 is damaged, the fixing bolt 29 is screwed and fixed directly to the hoistway side bracket 16B and is substantially fixed. The insertion hole 16E provided in the mounting end surface 16D of the guide rail side bracket 16A is prevented from moving by the cylindrical portion 29A of the fixing bolt 29 or the screw portion 29B. Therefore, the guide rail 14 is displaced at least by the outer diameter of the cylindrical portion 29A or the screw portion 29B of the fixing bolt 29 and the insertion hole 16E formed in the mounting end surface 16D of the guide rail side bracket 16A. The difference from the inner diameter can be suppressed. Considering the thickness of the small diameter portion of the vibration isolator washer 21, the difference is further reduced.

  Accordingly, the inner diameter of the insertion hole 16E formed in the mounting end surface 16D of the guide rail side bracket 16A is made slightly larger than the outer diameter of the cylindrical portion 29A of the fixing bolt 29, for example, the cylindrical portion 29A of the insertion hole 16E and the fixing bolt 23, Alternatively, the displacement of the guide rail 14 can be minimized if the dimensions are set such that the screw portion 29B and the small diameter portion of the vibration washer 21 substantially contact each other.

  As described above, according to this embodiment, since the displacement of the guide rail can be suppressed, the vibration caused by the deformation is transmitted to the guide shoe that slides on the guide rail while the car is running, which is caused by the deformation of the guide rail. Therefore, it is possible to solve problems such as giving noise and vibration to the car and giving anxiety to the passengers and also giving noise and vibration to the room of the building by this vibration.

  In this embodiment, the screw hole 28 is provided in the hoistway side bracket. However, the screw hole 28 is provided in the guide rail side bracket, and the fixing bolt 29 is inserted from the hoistway side bracket 16B so that the screw portion 29B is connected to the guide rail side bracket. Needless to say, the screw holes 28 of 16A may be screwed.

  Next, a fifth embodiment of the present invention will be described with reference to FIG. The same reference numerals as those in the embodiment shown in FIG. 4 indicate the same components or components having similar functions.

  8A and 8B, through holes 30 are directly formed at a predetermined interval on the attachment end surface 16C of the hoistway side bracket 16B.

  The cylindrical portion 31A of the fixing bolt 31 passes through the through hole 30. The inner diameter of the through hole 30 is set slightly larger than the outer diameter of the cylindrical portion 31A of the fixing bolt 31. Preferably, the dimensions are such that the through hole 30 and the cylindrical portion 31A of the fixing bolt 31 are in contact with each other. Therefore, the cylindrical portion 31 </ b> A of the fixing bolt 31 is hardly displaced in the through hole 30.

  The vibration isolator 18 is placed on the mounting end surface 16C of the hoistway side bracket 16B, and the mounting end surface 16D is placed on the anti-vibration material 18 through the insertion hole 16E of the guide rail side bracket 16A. The washer 21 and the washer 20 are inserted into a fixing bolt 29 and fastened with a nut 22 to be fixed.

  When the nut 22 is attached to the threaded portion 31B of the fixing bolt 31 and tightened, the pressing force (tightening force) generated by the nut 22 and the fixing bolt 31 is attached to the mounting end surface of the guide rail side bracket 16A via the washer 20 and the vibration washer 21. 16D and finally the vibration isolator 18 can be compressed by a predetermined compression allowance to firmly fix the guide rail side bracket 16A and the hoistway side bracket 16B.

  Here, a cylindrical portion 31A is formed on the base side of the fixing bolt 31, and the length t1 of the cylindrical portion 31A is the thickness t2 of the vibration isolator 18 and the thickness of the mounting end surface 16D of the guide rail side bracket 16. It is determined to be longer than the length obtained by adding the length t3. Therefore, when the nut 22 is fastened and fixed, the insertion hole 16E of the guide rail side bracket 16A and the insertion hole 18A of the vibration isolator 18 are positioned at the cylindrical portion 31A portion of the fixing bolt 31. This is expected to prevent the threaded portion 31B of the fixing bolt 31 from being damaged as described above.

  However, if the fixing bolt 23 is not used again by repair or inspection, or the screw portion 23 can be damaged, or if the screw portion 31B is protected by the small diameter portion of the vibration washer 21, The insertion hole 16E of the guide rail side bracket 16A and the insertion hole 18A of the vibration isolator 18 do not necessarily have to be positioned in the cylindrical portion 31A portion.

  Therefore, when using a fixing bolt in which the cylindrical portion 31A is omitted or a fixing bolt in which the cylindrical portion 31A is shortened, the insertion hole 16E of the guide rail side bracket 16A and the insertion hole 18A of the vibration isolator 18 are the screw portion 31B portion, or It may be present at a position straddling the threaded portion 31B and the cylindrical portion 31A.

  In this case, the small diameter portion of the vibration washer 21 is positioned between the insertion hole 16E of the guide rail side bracket 16A and the screw portion 31B of the fixing bolt 31, and has a vibration isolation function between the insertion hole 16E and the screw portion 31B. It has a function of preventing mutual damage by buffering direct contact between the threaded portion 31B and the insertion hole 16E.

  In the above, even when the guide rail 14 is displaced in a state where the vibration isolator 18 is damaged, the cylindrical portion 31A of the fixing bolt 31 is inserted into the through-hole 30 with substantially no gap in the hoistway side bracket 16B. The insertion hole 16E provided in the mounting end surface 16D of the guide rail side bracket 16A is prevented from moving by the cylindrical portion 31A of the fixing bolt 31, so that the function of the stopper is achieved. The displacement of the guide rail 14 is at least the difference between the outer diameter of the cylindrical portion 31A or the screw portion 31B of the fixing bolt 31 and the inner diameter of the insertion hole 16E formed in the mounting end surface 16D of the guide rail side bracket 16A. Can be suppressed. Considering the thickness of the small diameter portion of the vibration isolator washer 21, the difference is further reduced.

  Accordingly, the inner diameter of the insertion hole 16E formed in the mounting end surface 16D of the guide rail side bracket 16A is made slightly larger than the outer diameter of the cylindrical portion 31A of the fixing bolt 31, for example, the cylindrical portion 31A of the insertion hole 16E and the fixing bolt 31, Alternatively, the displacement of the guide rail 14 can be minimized if the dimensions are set so that the small diameter portions of the screw portion 31B and the vibration washer 21 substantially contact each other.

  As described above, according to the present embodiment, since the displacement of the guide rail can be suppressed, it is caused by the deformation of the guide shoe that is caused by the deformation of the guide rail and that slides on the guide rail while the car is running. Vibration can be transmitted, and noise and vibration can be given to the car to give passengers anxiety, and this vibration can also solve problems such as giving noise and vibration to the building room. .
