Abstract

PURPOSE:To safely move an elevator even when an elevator shaft pit-floor is apart from a basement floor by lifting an elevator device on the elevator shaft pit-floor up to a suitable position, by inserting an H-shaped steel into a space between a shock-absorber-installing-bed and the elevator-way, or by installing both a shim and a jack bolt between the pit-floor and the H-shaped steel. CONSTITUTION:An H-shaped steel 9 is inserted into a space between an elevator shaft pit-floor 7 and a shock-absorber-installing-bed 1. The H-shaped steel equipped with a reinforcing beam 8 is inserted into a space between the shock- absorber-installing-bed 1, on which a shock absorber 2 is mounted, and the elevator shaft pit-floor 7, in order to lift up both shock absorber 2 and shock- absorber-installing-bed 2. A steel plate 10 is embedded in the elevator shaft pit-floor 7 in advance, and a shim 11 is inserted into a space between the shim 11 and the H-shaped steel 9. Then, a fine adjustment is made by means of both the shim 11 and a jack bolt 12, so that the shock absorber 2 comes to a suitable position. With this contrivance, the elevator can safely be moved even after the elevator shaft pit-floor comes apart from a basement floor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator installed at a place where ground subsidence occurs, such as a landfill.

[0002]

2. Description of the Related Art Generally, an elevator pit is shown in FIG.
As shown in FIG. 2, a shock absorber installation base 1 is provided on the bottom, and a shock absorber 2 and a rail receiver 6 for receiving the lower ends of the guide rails 3 are provided on the top of the shock absorber installation base 1.

On the other hand, the clearance between the counterweight 4 and the shock absorber 2 is
Even when the elevator car 5 goes over the top floor and is pushed up, the counterweight 4 is gently stopped by the shock absorber 2, and the elevator car 5 has an appropriate size so that it can be stopped without hitting the top of the hoistway. Is taken.

Similarly, the clearance between the bottom of the elevator car 5 and the shock absorber 2 is gently stopped by the shock absorber 2 when the counterweight 4 is pushed up, and the counterweight 4 is lifted. 4 is of a suitable size so that it can be stopped without hitting the top of the hoistway. Further, since the shock absorber installation base 1 fixes the guide rail 3, the lower end of the guide rail 3 must be firmly received by the rail receiver 6.

Further, in an elevator installed at a place where the lowest floor and the hoistway pit floor are separated from each other, the gap between the bottom of the elevator car 5 and the shock absorber 2 and the gap between the counterweight 4 and the shock absorber 2 are greatly separated. Further, since the lower end of the guide rail 3 is separated from the guide rail receiver 6, the elevator cannot be installed easily.

[0006]

As described above, in the case of an elevator installed at a place where the lowest floor and the hoistway pit floor are separated from each other, the bottom of the elevator car 5 or the counterweight 4 and the shock absorber 2 are installed. There is a possibility that the gap becomes large and the function of the shock absorber 2 as a safety device cannot be maintained. Further, there is a problem that the lower end of the guide rail 3 cannot be received, and there is a risk that the installation of the guide rail 3 may be hindered.

The present invention has been made in order to solve the above problems, and its purpose is to lift the shock absorber installation base over the gap between the shock absorber and the bottom or counterweight of an elevator car that is unduly vacant. The purpose of the present invention is to provide an elevator that can be safely returned to an appropriate size and can receive a guide rail so that it can be operated safely even in a place where the floor of the lowest floor and the floor of the shaft pit are separated from each other.

[0008]

In order to achieve the above object, claim 1 of the present invention provides an elevator provided at a place where a floor of an elevator hoistway pit is separated from a floor of the elevator hoistway pit. It is characterized in that the elevator equipment installed in is lifted to an appropriate position. In addition, claim 2 inserts H steel between the shock absorber installation base installed in the elevator hoistway pit floor and the elevator hoistway pit floor to lift the elevator equipment installed in the pit floor to an appropriate position. Is characterized by. Further, a third aspect of the present invention is characterized in that the elevator equipment installed on the pit floor is lifted to an appropriate position by finely adjusting the shim and the jack bolt inserted between the elevator hoistway pit floor and the H steel.

[0009]

In the elevator constructed as described above, the shock absorber can be returned to an appropriate position by lifting the shock absorber installation base, so that the elevator is safe even after the bottom floor is separated from the hoistway pit floor. Can be operated.

[0010]

Embodiments of the present invention will now be described with reference to the drawings. 1A and 1B show a hoistway pit of an elevator according to an embodiment of the present invention. FIG. 1A is a front view and FIG. 1B is a side view. Since the elevator hoistway pit portion before the bottom floor and the hoistway pit floor are separated is the same as that of FIG. 3 described above, the description thereof is omitted.

As shown in FIG. 1, after the lowest floor and the hoistway pit floor are separated, the hoistway pit floor 7 is used as a treatment.
H steel 9 is inserted between the shock absorber installation base 1 and the shock absorber installation base 1. That is, here, the shock absorber installation base 1 in which the shock absorber 2 is installed
Then, the H steel 9 provided with the reinforcing beam 8 is inserted between the elevator hoistway pit floor 7 and the shock absorber 2 and the shock absorber installation base 1 are lifted. The elevator hoistway pit floor 7 is filled with a steel plate 10 in advance, and a shim 1 is placed between this and the H steel 9.
1 and the jack bolt 12 are used to finely adjust the shock absorber 2 to an appropriate position. The shock absorber installation base 1 and the H steel 9 are fixed by welding.

An embodiment in which the bottom floor and the hoistway pit floor are further separated after the first treatment will be described with reference to FIG. FIG. 2 (A) shows that, after the first treatment, when the bottom floor and the hoistway pit floor are further separated, as a treatment between the bottom 7 of the hoistway pit and the H steel 9 inserted during the first treatment. FIG. 7 is a diagram in which another H steel 13 is additionally inserted. FIG. 2B is a side view of FIG. Similar to the first treatment, the shim 11 and the jack bolt 12 inserted between the hoistway pit bottom 7 and the H steel 13 are used for fine adjustment, and the H steels are fixed to each other by welding.

[0013]

As described above, according to the elevator of the present invention, when the lowest floor and the hoistway pit floor are separated, the elevator can be restored in a short time. In addition, even if the bottom floor and the hoistway pit floor are separated several times, it can be easily dealt with.
