However, in Patent Document 1, since the upward load of the rope acting on the hoisting machine is supported only by the pit base via the rod, the load in the horizontal direction does not act on the guide rail and the rail bracket at normal times. When an earthquake occurs, a load is generated not only on the balance weight but also on the hoist due to rolling. In other words, in the guide rail near the hoisting machine, the horizontal direction of the load applied to the hoisting machine is added in addition to the balance weight, so when the sum of these two loads exceeds a certain level, the guide rail is deformed. There was a problem of doing. Therefore, in order to increase the strength of the guide rail or reduce the moment acting on the guide rail, it is necessary to reduce the mounting interval of the rail brackets and increase the number of rail brackets near the hoisting machine. Further, when the position of the hoisting machine is separated from the hoistway rear wall, the position of the load application point is separated, and the moment acting on the rail bracket is increased, so that it is necessary to increase the strength of the rail bracket. As described above, there is a problem that the cost is increased by increasing the strength of the rail bracket or increasing the number of rail brackets to be attached. In addition, if rail brackets cannot be installed at any level other than the floor level of the building, such as a flexible structure, the span of the rail brackets cannot be reduced, and it cannot be handled by increasing the number of rails. There was a problem that the cost was high.

The present invention has been made to solve the above-described problems. The purpose of the present invention is to cause the horizontal direction of the load applied to the hoisting machine to act directly on the rail bracket, not on the guide rail, so that Provided an elevator hoisting machine fixing device that can support the horizontal direction of the load applied to the hoisting machine with a simple configuration while suppressing a large cost increase without increasing the strength of the bracket or increasing the number of rail brackets. It is.

A fixing means to which the machine is fixed, a hoisting machine is connected and fixed, the hoisting machine is provided at a position separated from the bottom surface of the hoistway by a predetermined height, and the fixing means to which the hoisting machine is fixed; Load supporting means for supporting the horizontal direction of the load applied to the upper machine. It is connected and fixed to the fixing means and is attached to the fixing means so that when a load is applied to the hoisting machine, the load is transmitted to the first rail fixing means to support the horizontal direction of the load. It is.

In the present invention, when the hoisting machine receives a load, the horizontal direction of the load is transmitted to and supported by the rail bracket by the steadying beam attached to the raising base to which the hoisting machine is fixed. An elevator hoist fixing device capable of effectively supporting this load can be realized while suppressing a large cost increase without increasing the strength of guide rails or rail brackets or increasing the number of rail brackets.

Embodiment 1 FIG.
FIG. 1 is a perspective view showing the overall configuration of an elevator hoisting machine fixing device. 2 is a front view showing the main part of the elevator hoist fixing device of FIG. 1, FIG. 3 is a plan view showing the main part of FIG. 1, and FIG. 4 is an enlarged front view showing the main part of FIG. FIG. 5 is an enlarged side view showing the main part of FIG.

In the figure, the side surface of the hoistway 1 is formed of a plurality of walls 2, and a car 3 is a car that moves up and down in the elevator hoistway 1, and the car 3 is guided by a pair of guide rails 4a and 4b. It has become. The counterweight 5 moves in a direction opposite to the car 3, and the counterweight 5 is guided by a pair of guide rails 6a and 6b. The hoisting machine 7 is a thin hoisting machine disposed substantially parallel to one wall 2 in the plane cross section of the hoistway 1. Rail brackets 8a and 8b, which are first rail brackets, are fixed to one wall 2 of the hoistway 1, and the guide rails 6a and 6b are connected to one wall 2 of the hoistway 1 by the rail brackets 8a and 8b. It is fixed to.

The raising base 9 includes a hoisting machine fixing base (not shown) to which the hoisting machine 7 is fixed, and a leg portion 10 that supports the base. The lower part of the leg part 10 is attached to the pit base 11 provided in the bottom part of the hoistway 1, and the hoisting machine 7 is attached to the upper part. The height at which the hoisting machine 7 is fixed is adjusted by adjusting the length of the leg 10. The steadying beam 12, which is the first steadying beam, has one side fixed to the leg 10 and the other side connected and fixed to the rail brackets 8a and 8b. The steadying beam 12 is provided in a substantially horizontal direction, one side is attached to the leg 10 by a bolt 13 as a first bolt, and the other side is fixed to the rail brackets 8a and 8b by means such as welding. . The bolt 13 transmits the horizontal direction of the load applied to the hoisting machine 7 to the steadying beam 12 and has a predetermined length.

A bolt hole 14 that is a first hole through which the bolt 13 passes is provided on one side of the steadying beam 12. The bolt hole 14 has a shape that is large enough to allow the bolt 13 to pass therethrough. The leg portion 10 is provided with a bolt hole 15 as a second hole in order to allow the bolt 13 to pass through and attach one side of the steadying beam 12. The bolt hole 15 has a shape that has a predetermined length so that the bolt 13 can slide in the vertical direction, and a shape that has a width that allows the bolt 13 to penetrate in the horizontal direction. The leg 10 and one side of the steadying beam 12 are arranged such that the bolt hole 15 of the leg 10 is arranged on the front side, the bolt hole 14 of the steadying beam 12 is arranged on the back side, and the bolt from the bolt hole 15 side. 13 is penetrated in the horizontal direction, and is attached by a nut on the bolt hole 14 side.

At the attachment portion between the leg portion 10 and one side of the steadying beam 12, a slight gap is provided between the head of the bolt 13 and the bolt hole 15. On the bolt hole 14 side of the steadying beam 12 attached to the leg part 10, the bolt 13 is fixed to the steadying beam 12 by a nut. That is, the bolt 13 is attached in a state where it is not fastened on the bolt hole 15 on the front side of the leg portion 10. As a result, the relative displacement in the horizontal direction of the bolt 13 arranged so as to penetrate the bolt hole 14 and the bolt hole 15 is limited, but the relative displacement in the vertical direction is such that the bolt 13 is in the vertical direction of the bolt hole 15. Since it is slidable, it is not limited by the vertical length of the bolt hole 15.

Next, the operation of the present invention will be described. When shaking occurs in the hoistway 1 due to an earthquake or the like, a load acts on the hoisting machine 7. Since the horizontal direction of this load is transmitted as it is to the raising base 9 to which the hoisting machine 7 is fixed, the same load acts on the leg portion 10 as well. Here, the load transmitted to the leg 10 acts to displace the bolt hole 15 in the horizontal direction. When this load is applied to the bolt hole 15, the horizontal displacement of the bolt 13 disposed through the bolt hole 15 is limited by the bolt hole 15, so that the load is transmitted to the bolt 13. When this load is applied to the bolt 13, the same load is transmitted to one side of the steadying beam 12 from the bolt hole 14 through which the bolt 13 is passed. The transmitted load acts on the rail brackets 8a and 8b from the other side of the steadying beam 12. Since the rail brackets 8 a and 8 b are firmly attached to the wall 2, the horizontal direction of this load can be effectively supported by the reaction force of the wall 2.

At this time, the steadying beam 12 only needs to have a strength that can support only the horizontal direction of the load transmitted from the hoisting machine 7, and does not need strength to support a load other than the horizontal direction. . In other words, the steadying beam 12 can be provided with a necessary strength without increasing the thickness of the plate itself, for example, by adopting an L-shaped plate bending structure. Therefore, the steady-rest beam 12 can easily secure the necessary strength by using an inexpensive material such as generally available iron without using a special material as a constituent material, and is easy to process. Therefore, it can be constructed at a relatively low cost without a significant increase in cost.

Since it comprised as mentioned above, in the vertical projection surface of the clearance gap formed by the cage | basket | car 3 which raises / lowers the inside of the elevator hoistway 1 which has the wall 2, and the wall 2 of the one side, it is one side of the hoistway 1 A balance weight 5 which is arranged and balances with the car 3 and moves up and down in the hoistway 1; and guide rails 6a and 6b of the balance weight 5 which are erected in the hoistway 1 and guide the balance weight 5. Rail brackets 8a and 8b, which are first rail fixing means to which the guide rails 6a and 6b of the weight 5 are connected and fixed to the wall 2 on one side, and the hoistway 1 are provided in the vertical projection plane of the gap. The hoisting machine 7 disposed on the other side of the road 1 and the hoisting machine 7 are connected and fixed, and the hoisting machine 7 is provided at a position separated from the bottom surface of the hoistway 1 by a predetermined height. The raising base 9 that is a fixing means to which 7 is fixed and the horizontal direction of the load applied to the hoist 7 are supported. An anti-sway beam 12 which is a load support means for connecting, and the anti-sway beam 12 is connected and fixed to the rail brackets 8a and 8b and attached to the raising base 9, and when the load is applied to the hoisting machine 7. Since the load is transmitted to the rail brackets 8a and 8b to support the horizontal direction of the load, the strength of the guide rails 6a and 6b and the rail brackets 8a and 8b is increased, or the number of the rail brackets 8a and 8b is increased. Therefore, it is possible to realize an elevator hoisting machine fixing device capable of effectively supporting a horizontal load while suppressing a large cost increase.

In the first embodiment, the steadying beam 12 is connected and fixed to the rail brackets 8a and 8b. However, if the load acting on the steadying beam 12 can be supported, one of the rail brackets 8a and 8b is used. You may fix to one side.

On the other hand, when the hoistway 1 shakes due to an earthquake or the like, a load in the vertical direction as well as the horizontal direction may act on the hoisting machine 7. Since the vertical direction of this load is transmitted as it is to the raising base 9 to which the hoisting machine 7 is fixed, the same load acts on the leg portion 10 as well. This load acts to displace the bolt hole 15 of the leg 10 in the direction perpendicular to the bolt 13. That is, when the leg portion 10 is displaced in the vertical direction by this load, the bolt 13 and the bolt hole 15 that are penetrated in the horizontal direction are not fastened, and the vertical displacement is perpendicular to the bolt hole 15. Since it is not limited by a predetermined length in the direction, the displacement in the vertical direction is not transmitted to the bolt 13.

Therefore, when the leg portion 10 is displaced in the vertical direction, the bolt 13 and the bolt hole 15 slide relative to each other, so that the displacement of the leg portion 10 at this time is at least a predetermined value in the vertical direction of the bolt hole 15. Since only the length is not transmitted to the bolt 13, it is not supported by the steadying beam 12.

Since it comprised as mentioned above, it is provided in either the bolt 13 which transmits the horizontal direction of the load concerning the winding machine 7 to the steadying beam 12, and the raising stand 9 or the steadying beam 12, and penetrates the bolt 13 The bolt hole 14 is provided on the other of the raising base 9 and the steady beam 12 and has a predetermined length so that the bolt 13 can slide in the vertical direction, and the bolt 13 in the horizontal direction. , And a bolt 13 is provided so as to penetrate the bolt hole 14 and the bolt hole 15 in the horizontal direction. When a load acts on the hoisting machine 7, In the horizontal direction, the bolt 13 is limited to the bolt hole 14 and supported by the steady beam 12, and in the vertical direction of the load, the bolt 13 slides in the bolt hole 15 in the vertical direction and the steady beam When the load is applied to the hoisting machine 7 due to an earthquake or the like, the vertical direction of the load is fixed to the steady beam 12 so that the raising base 9 and the steady beam 12 are attached without being fastened. It can be prevented from being transmitted to. As a result, damage to the steady-state beam 12 can be prevented without increasing the strength of the steady-state beam 12, so that a large cost increase can be suppressed.

Embodiment 2. FIG.
FIG. 6 is a front view showing a hoisting machine fixing device configured by arranging a steadying beam on the hoisting machine 7 according to the second embodiment of the present invention. 7 is a plan view showing the main part of FIG. 6, and FIG. 8 is an enlarged front view showing the main part of FIG. In the hoisting machine fixing device according to Embodiment 2 of the present invention, one side is attached to the hoisting machine 7, and the other side is connected and fixed to rail brackets 17a and 17b which are first rail fixing means. 7 is provided with a steadying beam 16 which is a load supporting means for supporting the horizontal direction of a load applied to the same.

In the figure, the steadying beam 16 is attached on one side to the hoisting machine 7 and on the other side to rail brackets 17a and 17b. A bolt 18 as a first bolt is attached to the upper portion of the hoisting machine 7. The steadying beam 16 is provided in a substantially horizontal direction, one side is attached to the upper part of the hoisting machine 7 by a bolt 18 and the other side is fixed to the rail brackets 17a and 17b by means such as welding.

A bolt hole 19 that is a third hole through which the bolt 18 passes is provided on one side of the steadying beam 16. The bolt hole 19 has a shape that is large enough to allow the bolt 18 to pass therethrough. A bolt 18 for attaching one side of the steadying beam 16 through the bolt hole 19 is attached to the upper part of the hoisting machine 7. The upper part of the hoisting machine 7 and one side of the steadying beam 16 are arranged such that the bolt hole 19 of the steadying beam 16 is arranged on the upper surface side, and the upper part of the hoisting machine 7 is arranged on the lower surface side. The bolt 18 is passed through in a substantially vertical direction and attached to the upper side of the hoisting machine 7.

At the attachment portion between the hoisting machine 7 and one side of the steadying beam 16, a predetermined gap is provided between the head of the bolt 18 and the bolt hole 19. That is, the bolt 18 has a predetermined length and is attached in a state where it is not fastened to the bolt hole 19. Here, the predetermined length of the bolt 18 is, for example, the first embodiment. The length of the bolt hole 15 may be approximately the same as the vertical length. Thus, when the bolt 18 is displaced in the bolt hole 19 in the horizontal direction, the bolt 18 is limited to the bolt hole 19, so that the displacement of the bolt 18 is transmitted to the steadying beam 16.

On the other hand, when the bolt 18 is displaced in the vertical direction, the bolt 18 slides relative to the bolt hole 19 in the vertical direction. Therefore, the displacement is not limited at least for a predetermined length of the bolt 18. The displacement of 18 is not transmitted to the bolt hole 19.

Therefore, when the hoisting machine 7 is displaced in the vertical direction, the bolt 18 and the bolt hole 19 slide relative to each other, so that the displacement of the bolt 18 at this time is at least a predetermined length of the bolt 18. Is not transmitted to the bolt hole 19, and is not supported by the steadying beam 16.

Next, the operation of the present invention will be described. When shaking occurs in the hoistway 1 due to an earthquake or the like, a load acts on the hoisting machine 7. The horizontal direction of the load is transmitted as it is to the raising base 9 to which the hoisting machine 7 is fixed, and thus acts to displace the bolt 18 in the horizontal direction. When this load is applied to the bolt 18, the horizontal displacement of the bolt 18 disposed through the bolt 18 is limited by the bolt hole 19, so that the load is transmitted to the bolt hole 19. When this load acts on the bolt hole 19, the same load is transmitted from the bolt hole 19 to one side of the steadying beam 16. The transmitted load acts on the rail brackets 17a and 17b from the other side of the steadying beam 16. Since the rail brackets 17a and 17b are firmly attached to the wall of the hoistway 1, the horizontal direction of this load can be effectively supported by the reaction force of the wall.

At this time, the steadying beam 16 only needs to have a strength that can support only the horizontal direction of the load transmitted from the hoisting machine 7. Therefore, the steadying beam 16 is, for example, the first embodiment. Since it can be configured in the same manner as the steady-state beam 12, it can be configured relatively inexpensively without increasing the cost.

In FIG. 6, the steadying beam 12 according to the first embodiment may be arranged in addition to the steadying beam 16. In this case, since the effect of the first embodiment can be obtained in addition to the second embodiment, the horizontal direction of the load related to the hoisting machine 7 can be supported more strongly.

On the other hand, when the hoistway 1 shakes due to an earthquake or the like, a vertical load may act on the hoisting machine 7. This load acts on the bolt 18 attached to the upper part of the hoisting machine 7 in the same manner. That is, when the hoisting machine 7 is displaced in the vertical direction by this load, the bolt 18 is similarly displaced in the vertical direction. Here, since the bolt 18 arranged so as to penetrate is not fastened to the bolt hole 19 and the displacement in the vertical direction is not limited by a predetermined length, at least the bolt 18 is in the bolt hole in the vertical direction of the load. As long as 19 slides, the steady rest beam 16 is not transmitted.

Since it comprised as mentioned above, the bolt hole 19 which penetrates the volt | bolt 18 is provided in the steadying beam 16 instead of the volt | bolt hole 14 and the bolt hole 15, and while the volt | bolt 18 has a predetermined | prescribed length, When the load is applied to the hoisting machine 7, the bolt 18 is limited to the bolt hole 19 and supported by the steady beam 16. At the same time, the hoisting machine 7 and the steadying beam 16 are not fastened so that the bolt 18 is not supported by the steadying beam 16 by sliding the bolt 18 vertically through the bolt hole 19. Therefore, when a load is applied to the hoisting machine 7 due to an earthquake or the like, the strength of the guide rails 6a, 6b and the rail brackets 17a, 17b is increased or the rail brackets 17a, 17b, Without increasing the number of 7b, it is possible to support a horizontal load effectively while suppressing a large cost increase, and preventing the steady beam 16 from being damaged without increasing the strength of the steady beam 16 can do.

One side is connected and fixed to a wall-side bracket 20 provided on the wall 2 in the hoistway 1, and the other side is attached to the leg portion 10. The wall side bracket 20 is attached to a wall surface perpendicular to the wall 2 in the hoistway 1 to which the rail brackets 8a and 8b are fixed, and the steadying beam 21 is fixed to the wall side bracket 20 by means such as welding. Yes.

Next, the operation of the present invention will be described. When shaking occurs in the hoistway 1 due to an earthquake or the like, a load acts on the hoisting machine 7. Since the horizontal direction of the load is transmitted as it is to the raising base 9 to which the hoisting machine 7 is fixed, the same horizontal load acts on the leg portion 10 as well. Here, the load transmitted to the leg portion 10 acts on the wall side bracket 20 from one side of the steadying beam 21. Since the wall side bracket 20 is firmly attached to the wall 2 of the hoistway 1, the horizontal direction of this load can be effectively supported by the reaction force of the wall 2.

Since it comprised as mentioned above, it is provided in the wall 2 instead of the rail brackets 8a and 8b, and the wall side bracket 20 which fixes one side of the steadying beam 21 is provided, and the steadying beam 21 has one side wall side. It is connected and fixed to the bracket 20 and the other side is attached to the raising base 9, so that the cost is increased without increasing the strength of the guide rails 6a and 6b and the rail brackets 8a and 8b or increasing the number of the rail brackets 8a and 8b. An elevator hoist fixing device capable of effectively supporting a horizontal load while suppressing the load can be realized.

Instead of the steady beam 21, the rail brackets 8 a and 8 b side of the steady beam 16 in the second embodiment are cut, and the hoisting machine 7 side is stretched horizontally to the wall 2 side and stretched. One side is connected and fixed to a wall-side bracket 20 provided on the wall 2 in the hoistway 1, and the other side is provided with a steadying beam 16 ′ (not shown) configured to be attached to the hoisting machine 7. Thereby, an effect | action and effect equivalent to the steadying beam 21 can be show | played.

That is, the steady beam 21 and the steady beam 16 ′ in the third embodiment are different in that the substantially intermediate portion is attached to either the leg portion 10 or the hoisting machine 7, but the rest is the same. Therefore, there is no difference in the action of transmitting the horizontal direction of the load acting on the hoisting machine 7.

Since the configuration is as described above, the steadying beam 16 ′ is connected and fixed to the wall bracket 20 on one side, and attached to the hoisting machine 7 on the other side instead of the raising base 9, so that the guide rails 6 a and 6 b are connected. Further, it is possible to realize an elevator hoisting machine fixing device capable of effectively supporting a horizontal load while suppressing a large cost increase without increasing the strength of the rail brackets 17a and 17b or increasing the number of rail brackets 17a and 17b.

In FIG. 9, the steadying beam 12 or the steadying beam 16 may be arranged in combination with the steadying beam 21 or the steadying beam 16 ′. In this case, since the effect of the first embodiment or the second embodiment can be obtained in addition to the third embodiment, the horizontal direction of the load related to the hoisting machine 7 can be supported more strongly.

Embodiment 4 FIG.
FIG. 10 is a plan view showing a hoisting machine fixing device configured by arranging a steadying beam 22 and a steadying beam 23 according to Embodiment 4 of the present invention. The hoisting machine fixing device according to the fourth embodiment of the present invention is different in that the steadying beam 22 and the steadying beam 23 are provided in place of the steadying beam 12 according to the first embodiment. The same symbols are added to other similar parts, and the description is omitted.

Next, the operation of the present invention will be described. When shaking occurs in the hoistway 1 due to an earthquake or the like, a load acts on the hoisting machine 7. Since the horizontal direction of the load is transmitted as it is to the raising base 9 to which the hoisting machine 7 is fixed, the same horizontal load acts on the leg portion 10 as well. Here, the load transmitted to the leg 10 is transmitted from one side of the steadying beam 22 to the other side, and also acts on one side of the steadying beam 23 fixed to the other side. This load acting on one side of the steadying beam 23 acts on the rail bracket 24 from the other side.
