In Fig. 1, car 1 possesses the car frame 4 of cage 2 and supporting cage 2.Car frame 4 possesses: lower frame 5, its via be disposed in as the vibration-proof rubber 3 of vibrationproof portion material cage 2 car floor under, for supporting the load of cage 2; Upper ledge 6, it is disposed in the top at the top of cage 2; And vertical frame 7, it is uprightly disposed in the both sides of cage 2, for linking lower frame 5 and upper ledge 6.And guiding device 8 is disposed in 4 places up and down of car frame 4.In addition, emergency braking device 9 is disposed in 4 places up and down of car frame 4.
In the elevator forming like this, car 1 arrange for: guiding device 8 is engaged respectively with the head 13 of pair of guide rails 12, car 1 is suspended to the main rope (not shown) driving on rope sheave (not shown) around hanging over together with counterweight (not shown), and car 1 is guided by guide rail 12 and can be in the interior lifting of hoistway 10.In addition, counterweight is carried out lifting to reusing guide rail (not shown) guiding.In addition,, because guiding device 8 and emergency braking device 9 are known, therefore omit the explanation to its structure.
Then, with reference to Fig. 2 to Fig. 5, the maintenance structure of guide rail 12 is described.
As shown in Figure 3, railway clamp gripping member 15 is made the steel plate bending of the thickness of regulation, and it is shaped to the roughly Z-shaped being made up of following part: the installation portion 16 of rectangular flat shape, and it is installed on support 11; The press section 17 of rectangular flat shape, it presses the flange part 14 of guide rail 12; And connecting part 18, it links installation portion 16 and press section 17 in the mode parallel with the long side direction of rectangular flat shape.Bolt-through patchhole 19 is formed at the central portion of installation portion 16.
In press section 17, be formed with in parallel to each other three switch-in parts 20 vertical with the long side direction of the rectangular flat shape of press section 17 along long side direction with the interval of regulation.And, a side direction rear side extruding of the switch-in part of press section 17 20 is formed to the portion 21 of heaving.As shown in Figure 4, the cross sectional shape vertical with switch-in part 20 of heaving portion 21 is towards switch-in part 20 displacement and the shape of stretching out to flange part 14 sides smoothly.In addition, as shown in Figure 5, the cross sectional shape parallel with switch-in part 20 of heaving portion 21 is the shape that bends to smoothly convex to flange part 14 sides.In addition, heaving portion 21 is made by extrusion forming processing of plastic deformation etc.
For railway clamp gripping member 15, press section 17 is positioned on a flange part 14 of guide rail 12, installation portion 16 is posted by support 11.And, bolt 22 is inserted into the bolt-through patchhole 19 that is formed at installation portion 16 and the bolt-through patchhole (not shown) that is formed at support 11, nut (not shown) is screwed on to the axial region of the bolt 22 stretching out from support 11.Then, by nut screwing clamping, thereby by installation portion 16 and the fastening support 11 that is fixed on of flange part 14.Similarly, use railway clamp gripping member 15, bolt 22 and nut, by the support 11 that is fixed on that is fastening another flange part 14 of guide rail 12.Thus, as shown in Figure 2, guide rail 12 is supported on support 11 via railway clamp gripping member 15.In the railway clamp gripping member 15 of installing like this, the direction of the switch-in part 20 forming in press section 17 is horizontal direction, makes the lower side of the switch-in part 20 of press section 17 heave the portion of heaving 21 and flange part 14 butts that form to flange part 14 sides.
Railway clamp gripping member 15, because bolt 22 plays a role as leaf spring with the fastening force of nut, will be heaved portion 21 by being pressed in flange part 14.So elastic deformation occurs railway clamp gripping member 15, retrain the horizontal displacement of guide rail 12.In addition, the pressing force that the elastic deformation of railway clamp gripping member 15 produces acts on flange part 14 via the portion of heaving 21, comes at above-below direction support rails 12 by the friction force producing between the portion of heaving 21 and flange part 14.In addition, railway clamp gripping member 15, bolt 22 and nut have formed track holding device.
Here, in building, be accompanied by from be completed time living space weight increase, between floor produce sink.The decline that sinking between this floor has caused being fixed on the support 11 of building and has been fixed on the railway clamp gripping member 15 of support 11.And the decline of railway clamp gripping member 15 is passed to flange part 14 by the friction force producing between the portion of heaving 21 and flange part 14, to guide rail, 12 effects have the power (axial compressive force) that guide rail 12 is compressed vertically.And in the time that guide rail 12 has been acted on to excessive axial compressive force, guide rail 12 is bent.
Due to this heave the cross section vertical with switch-in part 20 of portion 21, comprise vertical direction cross section be from below towards switch-in part 20 smoothly to the shape of flange part 14 side displacements, therefore, in the time that the decline power of track holder 15 is excessive, railway clamp gripping member 15 is slided and is moved downwards on flange part 14., railway clamp gripping member 15 is slided downwards on flange part 14 with constant friction force.Thus, can not make excessive axial compressive force act on guide rail 12, can suppress the generation of the press-bending of guide rail 12.
In addition, while emergency braking device 9 being worked the abnormal descending speed of car 1 being detected, the load of car 1 acts on guide rail 12 via emergency braking device 9, and guide rail 12 is wanted to move downwards.The cross section that comprises vertical direction of heaving portion 21 becomes from below towards switch-in part 20 and to the shape of flange part 14 side displacements, the recuperability of the portion of heaving 21 of elastic deformation has occurred so that the mode effect of switch-in part 20 lateral lip portions 14 side displacements.So, heave the end face edge of switch-in part 20 sides of portion 21 to be trapped in the mode effect of flange part 14 of mobile guide rail 12 downwards, thereby produce larger friction force.Thus, the axial compression load producing at guide rail 12 as the burden load of emergency braking device 9 is by the Friction Compensation producing between the end face edge of switch-in part 20 sides of the portion of heaving 21 and flange part 14, and can not be delivered in guide rail 12 than railway clamp gripping member 15 position on the lower.
Support 11 to arrange interval L1 shorter than the interval L2 between the upper and lower emergency braking device 9 that is disposed in car 1.So, in the time that emergency braking device 9 is worked, can not be located between the railway clamp gripping member 15 that above-below direction is adjacent at two emergency braking devices 9 that arrange up and down of car 1.In other words, between the adjacent railway clamp gripping member 15 of above-below direction, only there is an emergency braking device 9.Thus, the railway clamp gripping member 15 immediately below that the axial compression load that results from guide rail 12 by the emergency braking device 9 arranging on the top of car 1 is positioned at this emergency braking device 9 compensates, and the railway clamp gripping member 15 immediately below that the axial compression load that results from guide rail 12 by the emergency braking device 9 arranging in the bottom of car 1 is positioned at this emergency braking device 9 compensates.Therefore, the axial compression load producing on the guide rail 12 between the adjacent railway clamp gripping member 15 of above-below direction is the half that emergency braking device 9 is only configured in the situation of upper next side of car 1, the sectional dimension miniaturization of guide rail 12 can be made, the cost degradation of guide rail 12 can be realized.
Fig. 6 is the main portion block diagram of the maintenance structure of the guide rail in the elevator of explanation embodiments of the present invention 2, and Fig. 7 is the exploded perspective view of the structure of the track holding device in the elevator of explanation embodiments of the present invention 2.
In Fig. 7, railway clamp gripping member 25 is made the steel plate bending of the thickness of regulation, and it is shaped to the roughly Z-shaped of formation: the installation portion 26 of rectangular flat shape, and it is installed on support 11; The press section 27 of rectangular flat shape, it presses the flange part 14 of guide rail 12; And connecting part 28, it links installation portion 26 and press section 27 in the mode parallel with the long side direction of rectangular flat shape, and bolt-through patchhole 29 is formed at the central portion of installation portion 26.
Then, with reference to Fig. 6, the maintenance structure of guide rail 12 is described.In addition for convenience of explanation, guide rail 12 flange part 14 is described, but another flange part 14 is supported in this explanation equally.
For railway clamp gripping member 25, press section 27 is positioned on a flange part 14 of guide rail 12, installation portion 26 is posted by support 11.And, bolt 22 is inserted into the bolt-through patchhole 29 that is formed at installation portion 26 and the bolt-through patchhole (not shown) that is formed at support 11, nut (not shown) is screwed togather to the axial region that is arranged on the bolt 22 stretching out from support 11.
Make the flange part 14 of chock 35 towards guide rail 12, the press section of surface plate 30 32 is positioned on flange part 14, make another distolateral back side that is posted by flange part 14 of backplate 36.And, bolt 22 inserting bolts are run through to patchhole 34,37, nut (not shown) is screwed together in to the axial region of the bolt 22 stretching out from backplate 36, chock 35 is arranged on to the top of the railway clamp gripping member 25 of guide rail 12.
And, by nut screwing clamping, thus by railway clamp gripping member 25 with flange part 14 is fastening is fixed on support 11, and make surface plate 30 and backplate 36 fastening fixing.Meanwhile, between fastening coupling plate 38 installation portion 26 and support 11 that is fixed on railway clamp gripping member 25, and by between fastening coupling plate 38 installation portion 31 and backplate 36 that is fixed on surface plate 30.And elastic deformation occurs railway clamp gripping member 25, retrain the horizontal displacement of guide rail 12.In addition, the pressing force that the elastic deformation of railway clamp gripping member 25 produces acts on flange part 14 via press section 27, comes at above-below direction support rails 12 by the friction force producing between press section 27 and flange part 14.In addition, there is elastic deformation in surface plate 30, and the pressing force that the elastic deformation of surface plate 30 produces acts on flange part 14 via chock 35, between chock 35 and flange part 14, produces friction force.Now, the friction force producing between chock 35 and flange part 14 is larger than the friction force producing between press section 27 and flange part 14.
In addition, other structure is configured to the same with above-mentioned embodiment 1.
In this embodiment 2, the decline that has caused being fixed on the support 11 of building and be fixed on the railway clamp gripping member 25 of support 11 due to the sinking between floor.And the decline of railway clamp gripping member 25 is passed to flange part 14 by the friction force producing between press section 27 and flange part 14, to guide rail, 12 effects have axial compressive force.
And in the time that the decline power of track holder 25 excessively increases, railway clamp gripping member 25 is slided and is moved downwards on flange part 14.Thus, can not make excessive axial compressive force act on guide rail 12, can suppress the generation of the press-bending of guide rail 12.
In addition, the decline of this railway clamp gripping member 25 is passed to surface plate 30 via coupling plate 38, and chock 35 declines with the decline interlock of railway clamp gripping member 25.Thus, the distance between railway clamp gripping member 25 and chock 35 is remained constant.
Then, while emergency braking device 9 being worked the abnormal descending speed of car 1 being detected, the load of car 1 acts on guide rail 12 via emergency braking device 9, and guide rail 12 is wanted to move downwards.And in the time that the decline power of guide rail 12 increases, guide rail 12 slides and moves downwards on the press section 27 of track holder 25.
Because the friction force between chock 35 and flange part 14 is larger than the friction force between press section 27 and flange part 14, therefore chock 35 links and declines with guide rail 12.And the end of chock 35 is trapped between press section 27 and flange part 14, this amount of being absorbed in increases, and increases at the friction force at this position.Thus, the axial compression load producing at guide rail 12 as the burden load of emergency braking device 9 is by the Friction Compensation producing to the portion of being absorbed in being absorbed between press section 27 and flange part 14 at chock 35.
In this embodiment 2, emergency braking device 9 is disposed in the upper and lower of car 1, and the interval between support 11 is narrower than the interval between emergency braking device 9, therefore, the same with above-mentioned embodiment 1, the axial compressive force that acts on guide rail 12 reduces, and can make the sectional dimension miniaturization of guide rail 12, can realize the cost degradation of guide rail 12.
Fig. 8 is the block diagram that the track holding device in the elevator of embodiments of the present invention 3 is shown, Fig. 9 is the main portion lateral plan of installing condition of the track holding device in the elevator of explanation embodiments of the present invention 3, the main portion lateral plan of the action of track holding device when Figure 10 is the emergency braking device work in the elevator of explanation embodiments of the present invention 3.
In Fig. 8, railway clamp gripping member 40 is made the steel plate bending of the thickness of regulation, and it is shaped to the roughly Z-shaped being made up of following part: the installation portion 41 of rectangular flat shape, and it is installed on support 11; The press section 42 of rectangular flat shape, it presses the flange part 14 of guide rail 12; And connecting part 43, it links installation portion 41 and press section 42 in the mode parallel with the long side direction of rectangular flat shape, and bolt-through patchhole 44 is formed at the central portion of installation portion 41.The variable plate 45 of friction force becomes U-shaped to make the steel plate bending of the thickness of regulation.
In addition, railway clamp gripping member 40, the variable plate 45 of friction force, bolt 22 and nut 23 have formed track holding device.
Then, with reference to Fig. 9, the maintenance structure of guide rail 12 is described.In addition for convenience of explanation, guide rail 12 flange part 14 is described, but another flange part 14 is supported in this explanation equally.
The terminal part of the convex of variable friction force plate 45 is positioned on a flange part 14 of guide rail 12, the press section of railway clamp gripping member 40 42 is positioned on the variable plate 45 of friction force, make installation portion 41 be posted by support 11.And, bolt 22 is inserted into the bolt-through patchhole 44 that is formed at installation portion 41 and the bolt-through patchhole (not shown) that is formed at support 11, nut 23 is screwed togather to the axial region that is arranged on the bolt 22 stretching out from support 11.And, nut 23 is tightened, thereby by installation portion 41 and the fastening support 11 that is fixed on of flange part 14.Now, the variable plate 45 of friction force becomes except the state from flange part 14 is outstanding fastening part.
Thus, there is elastic deformation in railway clamp gripping member 40, retrains the horizontal displacement of guide rail 12.In addition, the pressing force that the elastic deformation of railway clamp gripping member 40 produces acts on flange part 14 via press section 42 and the variable plate 45 of friction force, comes at above-below direction support rails 12 by the friction force producing between the variable plate 45 of friction force and flange part 14.
In addition, other structure is configured to the same with above-mentioned embodiment 1.
In this embodiment 3, the decline that has caused being fixed on the support 11 of building and be fixed on the railway clamp gripping member 40 of support 11 due to the sinking between floor.And the decline of railway clamp gripping member 40 is passed to flange part 14 by the friction force producing between the variable plate 45 of friction force and flange part 14, to guide rail, 12 effects have axial compressive force.
And in the time that the decline power of track holder 40 excessively increases, the variable plate 45 of friction force slides and moves downwards together with railway clamp gripping member 40 on flange part 14.Thus, can not make excessive axial compressive force act on guide rail 12, can suppress the generation of the press-bending of guide rail 12.
Then, while emergency braking device 9 being worked the abnormal descending speed of car 1 being detected, the load of car 1 acts on guide rail 12 via emergency braking device 9, and guide rail 12 is wanted to move downwards.The decline power of this guide rail 12 is passed to support 11 via railway clamp gripping member 40.So to support 11 action moments, as shown in figure 10, moment produces flexural deformation at support 11.Thus, 42 moments of press section of railway clamp gripping member 40 slide and decline and are equivalent to the distance of d on the variable plate 45 of friction force.So the region larger degree of crook of variable friction force plate 45 is pressed into flange part 14 by the press section 42 of railway clamp gripping member 40, the friction force producing between the variable plate 45 of friction force and flange part 14 increases.Thus, the axial compression load producing at guide rail 12 as the burden load of emergency braking device 9 is by the Friction Compensation producing between the variable plate 45 of friction force and flange part 14.
In this embodiment 3, emergency braking device 9 is disposed in the upper and lower of car 1, and the interval between support 11 is narrower than the interval between emergency braking device 9, therefore, the same with above-mentioned embodiment 1, the axial compressive force that acts on guide rail 12 reduces, and can make the sectional dimension miniaturization of guide rail 12, can realize the cost degradation of guide rail 12.
In addition, because the variable plate 45 of friction force is made into U-shaped, therefore, suppressed the disengaging of the variable plate 45 of friction force from railway clamp gripping member 40, and also obtained same effect in the situation that of support 11 K/UP distortion.
In addition, in above-mentioned embodiment 3, the variable plate 45 of friction force is made for U-shaped, but the shape of the variable plate of friction force is not defined as U-shaped, also can be formed as J word shape, the part that the ratio of this J word shape is clamped in the top side of part between press section and flange part is joined with flange part, and the part of side is from flange part is outstanding on the lower.
