Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guide pulley support device for an elevator in which a machine room is located below or above a hoistway, and more particularly to a guide pulley support device with improved fixation of a bearing support of a guide pulley. It is something.

As shown in FIGS. 1 and 2, in an elevator where the machine room 2 is located below or above the hoistway 1,
It is necessary to connect the riding gear 3 and the counterweight 4 with a rope 5 passing through a guide pulley 11 and a hoisting machine 6.

As shown in FIGS. 3 to 5, the guide pulley 11 has a pulley shaft 1 protruding from the center of the cross section of the guide pulley 11.
2 are rotatably supported by bearing supports 13, and the bearing supports 13 are attached to the wall surface of the hoistway 1 and horizontally arranged along the side surface of the pulley.
It is fixed at 15.

Generally, in the rope type elevator as described above, the guide pulley 11 must be disposed at the upper part of the hoistway 1 due to the positional relationship and moving direction of the ride height 3 and the counterweight 4.

For this reason, as mentioned above, the bearing beam 14.1 is placed at the top of the hoistway 1.
5, and in order to secure a working space when fixing the bearing support 13, the bearing beam 15 on the shaft wall side is located particularly away from the shaft wall surface.

Therefore, the planar space of the hoistway 1 has to be increased by the amount of the bearing beam 15.

The present invention addresses the above-mentioned problems, and its object is to provide an elevator guide pulley support device that reduces the planar space of a hoistway.

In order to achieve the above object, the present invention installs a bearing beam across the opposing walls of the hoistway, supports one end of two parallel bearing bases on the bearing beam, and supports the other end of the bearing The guide pulley is mounted on another wall of the road, and two bearing supports are mounted across the two parallel bearing bases, and the guide pulley is pivotally supported across the two bearing supports. That's what I did.

By arranging the bearing base in the same direction as the axis of the guide pulley, there is only one bearing beam that spans between the walls of the hoistway, thereby reducing the planar space of the hoistway. It is.

An embodiment of the present invention will be described below with reference to FIGS. 6 to 8.

The hoistway 1, the landing gear 3, the counterweight 4, the guide pulley 11, the pulley shaft 12, and the bearing beam 14 are the same as the conventional ones, so their explanation will not be repeated.

The major difference in this embodiment from the conventional one is that the bearing supports 16 and 17 located on both sides of the guide pulley 11 are not directly fixed onto the bearing beams, but each bearing support 16 and 17 is fixed directly on the bearing beam.
Both horizontal ends of the bearing bases 1B and 19 are fixed to the bearing beam 14 and the hoistway wall.

The bearing bases 18 and 19 are provided parallel to the direction along the pulley shaft 12, and the car side end is connected to the bearing beam 14.
The opposite side is fixed to the hoistway wall.

As described above, the bearing supports 16 and 17 are fixed on one side to the bearing beam 14 provided throughout the shaft, and on the other side are supported by the bearing base fixed to the wall of the shaft. Since the direction is the same as the pulley shaft 12, supporting work requires only some space on the longitudinal side of the bearing beam, and the guide pulley 11 can be brought as close to the hoistway wall surface as possible.

For this reason, there is no need to provide two bearing beams throughout the entire length of the hoistway to support the bearing support as in the past, and there is no need to provide a work space between the bearing beam on the hoistway wall and the hoistway wall. Since there is no need to provide a gap, the planar space of the hoistway can be reduced by that amount with the guide pulley support device according to this embodiment.

This is obtained because the bearing support body is supported on the support member (bearing base, bearing beam) in the pulley axial direction as described above.

In this way, the present invention installs a bearing beam across the opposing walls of a hoistway, supports one end of two parallel bearing bases on this bearing beam, and supports the other end on another wall of the hoistway. installation,
In addition, two bearing supports are installed across the two parallel bearing bases, and the guide pulley is pivotally supported across these two bearing supports, so that the bearing including the guide pulley is The support body can be brought closer to the shaft wall, and the number of bearing beams that span the opposing walls of the shaft can be reduced to one, so the planar space of the shaft can be reduced. can.
