And guiding device 8 is disposed in car4 places up and down of frame 4. In addition, emergency braking device 9 is disposed in 4 places up and down of car frame 4.
Support 11 is arranged on the beam (not shown) that is arranged at hoistway 10, the interval (L1) to specify in hoistway 10Be equipped with multiple supports 11 at above-below direction. Pair of guide rails 12 is made into respectively by head 13 and flange part 14 and formsRoughly T word shape cross section, guide rail 12 is linked to each support 11 by railway clamp gripping member 15, and separates the distance of regulationFrom, in hoistway 10, extend and arrange along the vertical direction. Here, the interval L1 ratio that arranges of support 11 is disposed in sedan-chairInterval L2 between the upper and lower emergency braking device 9 in railway carriage or compartment 1 is short.
In the elevator forming like this, car 1 arranges as the head 13 that makes guiding device 8 and pair of guide rails 12Engaging respectively, car 1 is suspended to the main rope driving on rope sheave (not shown) around hanging over together with counterweight (not shown)Rope (not shown), car 1 is guided by guide rail 12 and can be in the interior lifting of hoistway 10. In addition, counterweight is led reusingLifting is carried out in 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, its be shaped to byThe roughly Z-shaped that following part forms: the installation portion 16 of rectangular flat shape, it is installed on support 11; Rectangular flat shapePress section 17, it presses the flange part 14 of guide rail 12; And linking part 18, its with the length of rectangular flat shapeThe parallel mode of edge direction links installation portion 16 and press section 17. Bolt-through patchhole 19 is formed at installation portion 16Central portion.
In press section 17, along long side direction with the interval of regulation be formed with in parallel to each other three with the square of press section 17The switch-in part 20 that the flat long side direction of shape is vertical. And, by a side direction back of the body of the switch-in part of press section 17 20Face side extruding and form the portion 21 of heaving. As shown in Figure 4, heave the cross sectional shape vertical with switch-in part 20 of portion 21Towards switch-in part 20 displacement and the shape of stretching out to flange part 14 sides smoothly. In addition, as shown in Figure 5, drumThe cross sectional shape parallel with switch-in part 20 that plays portion 21 is the shape that bends to smoothly convex to flange part 14 sides.In addition, heaving portion 21 is made by extrusion modling 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, by installation portion16 are posted by support 11. And, bolt 22 is inserted into bolt-through patchhole 19 Hes that are formed at installation portion 16The bolt-through patchhole (not shown) that is formed at support 11, is screwed on nut (not shown) from support 11 and stretchesThe axial region of the bolt 22 going out. Then, by nut screwing clamping, thereby by installation portion 16 with flange part 14 is fastening is fixed onSupport 11. Similarly, use railway clamp gripping member 15, bolt 22 and nut, by another flange part of guide rail 12The 14 fastening supports 11 that are fixed on. Thus, as shown in Figure 2, guide rail 12 is supported on support via railway clamp gripping member 1511. 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 level sideTo, make the lower side of the switch-in part 20 of press section 17 heave the portion of heaving 21 and the flange part that form to flange part 14 sides14 butts.
Railway clamp gripping member 15, because bolt 22 plays a role as leaf spring with the fastening force of nut, will be heaved portion 21By being pressed in flange part 14. So strain occurs railway clamp gripping member 15, retrain the horizontal displacement of guide rail 12.In addition, the pressing force that the strain of railway clamp gripping member 15 produces acts on flange part 14 via the portion of heaving 21,Come at above-below direction support rails 12 by the frictional 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, produceIt is heavy to give birth to. The rail that sinking between this floor has caused being fixed on the support 11 of building and has been fixed on support 11The decline of road holder 15. And the decline of railway clamp gripping member 15 is by between the portion of heaving 21 and flange part 14The frictional force producing and be passed to flange part 14, to guide rail 12, effect has the power (axle that guide rail 12 is compressed verticallyTo compression stress). 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 courtTowards switch-in part 20 smoothly to the shape of flange part 14 side displacements, therefore, in the decline power of track holder 15When excessive, railway clamp gripping member 15 is slided and is moved downwards on flange part 14. , railway clamp gripping member 15 is with perseveranceFixed frictional force is slided downwards on flange part 14. Thus, can not make excessive axial compressive force act on guide rail12, can suppress the generation of the press-bending of guide rail 12.
In addition, while emergency braking device 9 being worked the abnormal decrease speed of car 1 being detected, car 1 carryLotus acts on guide rail 12 via emergency braking device 9, and guide rail 12 is wanted to move downwards. It is perpendicular to heave comprising of portion 21Nogata to cross section become from below towards switch-in part 20 and to the shape of flange part 14 side displacements, elasticity occurredThe recuperability of the portion of heaving 21 of distortion is so that the mode effect of switch-in part 20 lateral lip portions 14 side displacements. InTo heave the end face edge of switch-in part 20 sides of portion 21 to be trapped in the flange part 14 of mobile guide rail 12 downwardsMode effect, thereby produce larger frictional force. Thus, as the burden load of emergency braking device 9 andThe axial compression load producing at guide rail 12 is by end face edge and the flange part 14 of switch-in part 20 sides in the portion of heaving 21Between the Friction Compensation that produces, and can not be delivered in guide rail 12 than railway clamp gripping member 15 position on the lower.
Emergency braking device 9 is configured in car 1 up and down. So, on left side and the right side of car 1, when upperIn the situation that the emergency braking device 9 of lower configuration is worked simultaneously, the load that each emergency braking device 9 is born is for exampleEmergency braking device 9 is only configured in the half of the situation of the below of car 1. , each in the configuration up and down of car 1The stopping power of individual emergency braking device 9 be only configured in upper next side of car 1 emergency braking device 9 oneHalf, can realize the miniaturization of emergency braking device 9.
Support 11 arrange interval L1 than the interval L2 between the upper and lower emergency braking device 9 that is disposed in car 1Short. So, in the time that emergency braking device 9 is worked, at two emergency braking devices 9 that arrange up and down of car 1Can not be located between the railway clamp gripping member 15 that above-below direction is adjacent. In other words, at the adjacent railway clamp of above-below directionBetween gripping member 15, only there is an emergency braking device 9. Thus, by promptly stopping of arranging on the top of car 1The locking apparatus 9 and axial compression load that results from guide rail 12 is positioned at the track immediately below of this emergency braking device 9Holder 15 compensates, and results from the axial of guide rail 12 by the emergency braking device 9 arranging in the bottom of car 1The railway clamp gripping member 15 immediately below that compressive load is positioned at this emergency braking device 9 compensates. Therefore, at upper and lowerThat emergency braking device 9 is only joined to the axial compression load producing on the guide rail 12 between adjacent railway clamp gripping member 15Put the half in the situation of upper next side of car 1, can make the sectional dimension miniaturization of guide rail 12, can realizeThe cost degradation of guide rail 12.

In Fig. 7, railway clamp gripping member 25 is made the steel plate bending of the thickness of regulation, and it is shaped to formationRoughly Z-shaped: the installation portion 26 of rectangular flat shape, 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 linking part 28, it is with the side parallel with the long side direction of rectangular flat shapeFormula links installation portion 26 and press section 27, and bolt-through patchhole 29 is formed at the central portion of installation portion 26.
Surface plate 30 is shaped to by consisting of roughly the following part that the steel plate bending of the thickness of regulation is madeZ-shaped: the installation portion 31 of rectangular flat shape; The press section 32 of rectangular flat shape, it presses the flange part 14 of guide rail 12;And linking part 33, it links installation portion 31 and press section 32 in the mode parallel with the long side direction of rectangular flat shape,Bolt-through patchhole 34 is formed at the central portion of installation portion 31. And, chock 35 is fixed on to press section 32The back side. In addition, backplate 36 is made for rectangular flat shape with the steel plate of the thickness of regulation, and at one end side is formed withBolt-through patchhole 37.
Web 38 is made for rectangular flat shape with the steel plate of the thickness of regulation, distolateral being formed with of a sidepieceThe otch 39a of U-shaped, at another distolateral otch 39b that is formed with J word shape of a sidepiece. In addition railway clamp,Gripping member 25, the surface plate 30 that is fixed with chock 35, backplate 36, web 38, bolt 22 and nut formTrack holding device.
Then, with reference to Fig. 6, the maintenance structure of guide rail 12 is described. In addition, for convenience of explanation, to guide railA flange part 14 of 12 describes, 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, by installation portion26 are posted by support 11. And, bolt 22 is inserted into bolt-through patchhole 29 Hes that are formed at installation portion 26The bolt-through patchhole (not shown) that is formed at support 11, screws togather nut (not shown) to be arranged on from supportThe axial region of 11 bolts that stretch out 22.
Make the flange part 14 of chock 35 towards guide rail 12, the press section of surface plate 30 32 is positioned in to flangeIn portion 14, make another distolateral back side that is posted by flange part 14 of backplate 36. And, bolt 22 is inserted to spiral shellBolt runs through 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.
Web 38 is so that bolt 22 is installed in the installation of railway clamp gripping member 25 by the mode in otch 39a, 39bBetween portion 26 and support 11 and between the installation portion 31 and backplate 36 of surface plate 30.
And, by nut screwing clamping, thereby by railway clamp gripping member 25 and the fastening support 11 that is fixed on of flange part 14, andMake surface plate 30 and backplate 36 fastening fixing. Meanwhile, by the fastening web 38 railway clamp gripping member 25 that is fixed onInstallation portion 26 and support 11 between, and by fastening web 38 installation portion 31 that is fixed on surface plate 30 and the back of the bodyBetween panel 36. And strain occurs railway clamp gripping member 25, retrain the horizontal displacement of guide rail 12. ThisOutward, the pressing force that the strain of railway clamp gripping member 25 produces acts on flange part 14 via press section 27, borrowsHelp the frictional force producing between press section 27 and flange part 14 to come at above-below direction support rails 12. In addition table,There is strain in panel 30, the pressing force that the strain of surface plate 30 produces acts on protruding via chock 35Edge 14 produces frictional force between chock 35 and flange part 14. Now, chock 35 and flange part 14 itBetween produce frictional force than between press section 27 and flange part 14 produce frictional force large.
In addition, other structure is configured to the same with above-mentioned embodiment 1.
In this embodiment 2, due to the sinking between floor caused being fixed on building support 11 andBe fixed on the decline of the railway clamp gripping member 25 of support 11. And the decline of railway clamp gripping member 25 is passed through in press section27 and flange part 14 between the frictional force that produces and be passed to flange part 14, to guide rail 12, effect has axial compressive force.
And in the time that the decline power of track holder 25 excessively increases, railway clamp gripping member 25 is sliding on flange part 14Move and move downwards. Thus, can not make excessive axial compressive force act on guide rail 12, can suppress guide rail 12The generation of press-bending.
In addition, the decline of this railway clamp gripping member 25 is passed to surface plate 30 via web 38, chock 35 and trackThe decline of holder 25 links and declines. Thus, the distance between railway clamp gripping member 25 and chock 35 is remainedConstant.
Then, while emergency braking device 9 being worked the abnormal decrease speed of car 1 being detected, car 1 carryLotus acts on guide rail 12 via emergency braking device 9, and guide rail 12 is wanted to move downwards. And, when guide rail 12When decline power increases, guide rail 12 slides and moves downwards on the press section 27 of track holder 25.
Because the frictional force between chock 35 and flange part 14 is larger than the frictional 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 in press section 27 and flange partBetween 14, this amount of being absorbed in increases, and increases in the frictional force at this position. Thus, as emergency braking device 9Burden load and the axial compression load that produces at guide rail 12 by chock 35 to press section 27 and flange part 14Between the Friction Compensation that produces of the portion of being absorbed in that is absorbed in.
In this embodiment 2, emergency braking device 9 is disposed in the upper and lower of car 1, and support 11Between interval narrower than the interval between emergency braking device 9, therefore, the same with above-mentioned embodiment 1, act onThe axial compressive force of guide rail 12 reduces, can make the sectional dimension miniaturization of guide rail 12, can realize guide rail 12Cost degradation.

The variable plate 45 of frictional 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 frictional force, bolt 22 and nut 23 have formed track maintenance dressPut.
Then, with reference to Fig. 9, the maintenance structure of guide rail 12 is described. In addition, for convenience of explanation, to guide railA flange part 14 of 12 describes, but another flange part 14 is supported in this explanation equally.
The terminal part of the convex of variable frictional force plate 45 is positioned on a flange part 14 of guide rail 12, by trackThe press section 42 of holder 40 is positioned on the variable plate 45 of frictional force, makes installation portion 41 be posted by support 11. AndAnd, bolt 22 is inserted into the bolt-through patchhole 44 that is formed at installation portion 41 and the bolt that is formed at support 11Run through patchhole (not shown), 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, frictional force canBecoming plate 45 becomes except the state from flange part 14 is outstanding fastening part.
Thus, there is strain in railway clamp gripping member 40, retrains the horizontal displacement of guide rail 12. In addition railway clamp,The pressing force that the strain of gripping member 40 produces acts on flange part via press section 42 and the variable plate 45 of frictional force14, come at above-below direction support rails by the frictional force producing between the variable plate 45 of frictional force and flange part 1412。
