BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator for reverse hitting work and a method for adding guide rails of the elevator.

[0002]

2. Description of the Related Art In the case of constructing a structure by a reverse striking method, a floor on the first floor above the ground (or a floor on the first floor below the ground) is constructed first, and under the floor is excavated from there, and gradually excavated to the deepest part of the underground. The underground skeleton will be constructed one by one while adjusting to the excavation depth. At this time, an elevator will be installed to lift the cargo underground.

[0003] In this elevator, for example, as shown in Fig. 8, a guide rail 2 is set underground from an intake 1 opening on the floor of the first floor above the ground, and an appropriate portion thereof is fixed to the floor.
The cage 3 is attached to the guide rail 2 so as to be able to move up and down, and is moved up and down by a motor 4 arranged below the cage 3.

Then, as the construction of the underground skeleton progresses, the guide rails are successively extended and extended. As an example of a method of adding the guide rails, conventionally, as shown in FIG. 8, a base 5 at the lower end of the guide rail 2 is installed on the root bottom 6 to receive the vertical force of the guide rail 2 at the lower part. The guide rail 2 is newly added to the lower part of the guide rail each time according to the excavation depth.

Further, as shown in FIG. 9, a support member 8 is attached to the upper part of the guide rail 2 and the vertical force of the guide rail 2 is supported by the floor surface 7 on the first floor via the support member 8. In this state, a guide rail 2 is newly added to the lower part of the guide rail each time according to the excavation depth.

[0006]

The guide rail 2 which has been newly excavated on the guide rail 2 which has already been installed is newly added by the newly excavated depth.
In the conventional method of adding to the lower part of the installed guide rail 2 as in the conventional case, it is difficult to provide a safety facility because the work is performed below the elevator cage, and the work of adding the rail is performed at a high place. It is difficult to work and is not safe.

[0007] An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and when the guide rails 2 are newly added to the already installed guide rails by the newly excavated depth, the operation of adding the guide rails is flat and safe. It is an object of the present invention to provide an elevator for reverse hitting work which can be easily performed at a place, and a method of adding guide rails of the elevator.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a side view showing an embodiment of a method of reinforce an elevator for reverse hitting and a guide rail of an elevator according to the present invention, and FIG. 2 is a front view of the same, and the elevator of the present invention is also a conventional one already described with reference to FIGS. As in the example, a guide rail 2 is set underground from an intake port 1 opening to a floor 7 on the first floor above the ground, and a cage 3 is attached to the guide rail 2 so as to be able to move up and down.

As a mechanism for raising and lowering the cage 3, a motor 4 is provided on a frame 10 provided below the cage 3 as shown in FIG. A gear 9 is provided. Further, rollers 11 to be combined with the guide rails 2 from the frame body 10 are provided at upper and lower positions to face each other.

The guide rail 2 is provided with a pair of channel-like members back to back as shown in FIGS.
As an example, a single unit having a length of 1508 mm is connected vertically. Then, a rack 12 with which the gear 9 is engaged is provided on the inner side surface of the guide rail 2 along the length direction.

In the elevator provided with such an elevating mechanism, the guide rail 2 is moved up and down by the same member as the channel-like member constituting the guide rail 2 on the side of the frame parallel to the guide rail 2 as an elevating mechanism of the guide rail 2. Guide rails 13 are connected by a connecting member 22.

On the other hand, as shown in FIG. 6, a wall connecting member 14 is fixed to the floor surface on the skeleton side with an anchor bolt 15, and a roller 16 provided on the wall connecting member 14 as shown in FIG. The groove of the rail 13 is engaged. The arrangement interval of the wall connecting members 14 is, for example, 5500 mm at the maximum.

As described above, the cage 3 is provided on the guide rail 2 so as to be movable up and down, and the guide rail 2 is connected to the wall.
It is provided on the frame via 14 so as to be able to move up and down.

In the present invention, a cage fixing outrigger 17 for fixing the cage 3 to the floor of the skeleton is provided on the cage 3, and a base at the lower end of the guide rail 2 is provided.
18 has an outrigger 19 for fixing the base, which can be installed on the floor of the skeleton.

As shown in FIG. 3, the outrigger 17 for fixing the cage is formed by connecting an arm 17b made of H steel to a tip of an attachment member 17a made of H steel attached to a lower portion of the frame 10, and Arm 17b is connected piece 20
And can be detachably attached by bolts 21.

As shown in FIG. 4, the base 18 is formed of a plate-like member, on which the guide rails 2 and 13 stand.

The outrigger 19 for fixing the base has the same configuration as the outrigger 17 for fixing the cage, as shown in FIG. The arm 19b is connected to the mounting member 19a by a connecting piece 20 and a bolt 21 so as to be rotatable.

Next, a description will be given of a method of adding a new single guide rail 2 to the already installed guide rail 2 by the newly excavated depth. For example, when the construction is performed up to the floor of the second basement floor, and excavation is performed to a depth of the third basement floor, the base 18 is installed on the floor of the second basement floor. In this state, as shown in FIG. 1, the outrigger 19 for fixing the base is placed on the floor of the second basement floor with the arm 19b in the horizontal position, and the vertical force of the guide rail 2 is Is supported on the floor of the second basement floor.

Assembling the elevator in such a state,
The motor 4 is driven to move the cage 3 up and down along the guide rail 2 and excavate below the second basement floor. When the excavation is completed, the guide rail 2 is added to the depth of the excavation, but the base 18 is fixed to the second basement floor with the base fixing outrigger 19 and the first floor above the ground. The floor surface 7 is used as a work area for replenishment, and the guide rail 2 having a length corresponding to the excavation depth is replenished above the guide rail 2 already installed.

Next, the outrigger 17 for fixing the cage is extended to the floor 7 on the first floor above the ground, and the cage 3 is fixed on the first floor above the ground. In this state, the motor 4 is driven to pull up the guide rail 2. When the motor 4 is driven because the cage 3 is fixed, the gear 9 rotates and moves along the rack 12 so that the guide rail 2 is raised. At this time, since the guide rail 13 connected to the guide rail 2 moves upward along the roller 16 provided on the wall connecting member 14, the horizontal force of the guide rail 2 is supported by the wall connecting member 14. The guide rail 2 rises smoothly.

If the guide rail 2 is pulled up, the base
Loosen the bolt 21 of 18, and pivot the arm 19b upward at the connection piece 21 to fold the outrigger 19 for fixing the base,
Next, the motor 4 is rotated in the reverse direction, the guide rail 2 is lowered this time, and the base 18 at the lower end is set on the root cutting bottom 6. The elongated guide rail 2 is set.

The structure of the wall connecting member 14 is not limited to the above-described one.
The roller 16 may be protruded from the side of the body in the direction of the skeleton, and the guide rail 23 engaged with the roller 16 may be fixed to the skeleton side.

[0028]

As described above, according to the method of adding the guide rails of the elevator for reverse hitting and the elevator according to the present invention, only the guide rails can be moved up and down while the cage is fixed.
It can be performed in a safe and flat place such as the floor of a floor, and only the guide rails 2 need to be lowered after replenishment, which improves the workability of replenishment.

Further, since the vertical load of the guide rail can be supported by the frame by the base fixing outrigger provided at the lower end, the guide rail can be reliably added upward in this state.

Further, since the guide rail is moved up and down by using a motor for moving up and down the cage, a new mechanism for raising and lowering the guide rail may be provided with an outrigger so that the guide rail can be moved up and down with respect to the frame. And can be easily applied to existing elevators.
