Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an auxiliary guide device for a counterweight for an elevator.

[Technical background of the invention]

The elevator car and counterweight are each suspended from both ends of a main rope wound around a hoist placed above the hoistway, and when the hoist is operated, the car guide rail and It is designed to move up and down along the counterweight guide rail. Figure 1 shows a general configuration for guiding a counterweight to a guide rail. This counterweight is guided to two left and right counterweight guide rails 4, 4 via main guide shoes 3, 3 provided above and below both sides of the suspension frame, and It is designed to move up and down along rails 4, 4. However, if the counterweight is guided to the guide rails 4, 4 only by the upper and lower main guide shoes 3, 3 on both sides, when the counterweight vibrates due to an earthquake, etc., the inertia of the counterweight Since the force acts intensively on the guide rails 4, 4 through the main guide devices 3, 3, the portions of the guide rails 4, 4 that are in contact with the main guide shoes 3, 3 are bent and the main guide shoes 3, 3 are bent. may come off the guide rails 4, 4. Note that the guide rails 4, 4 are connected to brackets 14, 14 provided at appropriate intervals.
Since the guide rails 4, 4 are fixed to the hoistway wall of the building through the guide rails, deflection occurs in the portion between the fixed portions, that is, the portion not restrained by the hoistway wall.

Therefore, recently, in order to prevent the counterweight from coming off the rail as described above, an auxiliary guide device has been installed on both sides of the hanging frame 1, approximately midway between the upper and lower main guide shoes 3, and this auxiliary guide device is used. It has been considered to reduce the deflection of the guide rails 4, 4. In FIGS. 1 and 2, reference numeral 5 indicates the auxiliary guide device, and as this auxiliary guide device 5, a shoe member having a shape as shown in FIG. 3 has conventionally been used. This shoe member has an integral structure in which a pair of vertical guide plates 7, 7 are protruded from the front surface of a base plate 6 attached to the side frame portion 1a of the hanging frame 1. It is attached to the hanging frame side frame portion 1a by bolts 9a, 9b inserted through the provided attachment holes 8, 8, as shown in FIG. The shoe member also maintains the distance X between the base plate 6 and the side edge of the guide rail 4 and the distance Y between the guide plates 7, 7 and the guide rail 4 surface between the main guide shoes 3, 3 and the guide rail 4. The shoe member is provided with a distance slightly larger than the distance between the side edge and the rail surface, so that the shoe member does not normally come into sliding contact with the guide rail 4. In addition,
Reference numeral 11 denotes a shim inserted between the base plate 6 and the hanging frame side frame portion 1a in order to adjust the distance between the base plate 6 of the shoe member and the side edge of the guide rail.

To explain the deflection of the guide rail 4 when the shoe member is provided, the inertial force of the counterweight when the counterweight is vibrated due to an earthquake etc. The main guide shoes 3, 3 of the guide rail 4 act in a concentrated manner on the part of the guide rail 4 that is in contact with the main guide shoes 3, 3.
On the other hand, when the upper and lower main guide shoes 3, 3 of the hanging frame 1 contact the guide rail 4 and are restrained, the inertial force of the weight members 2, 2 inside the hanging frame 1 acts on the hanging frame 1 as a bending force. As a result, the side frame portion 1a of the hanging frame 1 is deflected, and as a result, the shoe member provided in the middle of the hanging frame side frame portion 1a comes into contact with the guide rail 4 (the hanging frame When the direction of deflection of the side frame portion 1a is in the width direction of the hanging frame, the base plate 6 comes into contact with the side edge of the guide rail, and when the direction of deflection is in the front-rear direction of the hanging frame, the guide plate 7 comes into contact with the guide rail surface.) . When the shoe member comes into contact with the guide rail 4, the guide rail 4 also receives the intermediate part of the hanging frame side frame part 1a, so that further deflection of the hanging frame side frame part 1a is prevented. Further, the inertial force of the counterweight is distributed to three locations via the upper and lower main guide shoes 3, 3 and the intermediate shoe member. Therefore, the amount of deflection of the portion of the guide rail 4 where the main guide shoes 3, 3 and the shoe member are in contact is considerably reduced compared to the case where the shoe member is not provided, and as a result, the balance weight is prevented from coming off the rail. Prevented. Providing the auxiliary guide device 5 on both sides of the hanging frame 1 approximately in the middle of the upper and lower main guide shoes 3, 3 is useful for balancing when the counterweight is vibrated due to an earthquake or the like. This is effective in preventing the weight from falling off the rail.

[Problems with background technology]

However, since the conventional auxiliary guide device consists of a shoe member having a shape as shown in FIG. 3, it has the problem that attachment to the hanging frame 1 is very troublesome. That is, since the auxiliary guide device is provided so as not to be in contact with the guide rail 4 at all times, it is attached to the suspension frame 1 after the counterweight is set on the guide rail 4 at the elevator installation site. Since the show member, which is a conventional auxiliary guide device, is an integral piece with the shape shown in FIG.
First, the show member must be fitted onto the guide rail 4 above or below the hanging frame 1, and then the show member must be fed to the middle part of the hanging frame side frame portion 1a. Therefore, the show member must be set at the mounting position. The work is difficult. Moreover, the shoe member has a mounting hole 8 provided in the base plate 6,
8 are provided on both sides of the pair of guide plates 7, 7, so that the bolts 9a on the hoistway wall 12 are tightened by the guide rail 4 and the hanging frame side frame 1a.
Even if you try to use the gap between
is in the way, and therefore the bolts 9 on the hoistway wall 12 side
Bolt tightening work is difficult because bolt a must be tightened within the narrow space between the counterweight and the hoistway wall 12. In addition, in recent years, there has been a growing desire to reduce the ratio of elevator space to the floor area of the building, that is, the elevator occupancy rate, in order to make effective use of building space. If the width dimension has to be reduced, and if an attempt is made to reduce only the hoistway without changing the size of the car, the wrinkles will be reflected in the gap dimension A between the center of the counterweight and the hoistway wall 12. Because it comes,
In such a case, the counterweight and hoistway wall 12
It becomes difficult to turn the bolt tightening tool within the space between the two, and in the worst case, the elevator installation process may have to be changed in order to install the auxiliary guide device.

[Purpose of invention]

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to completely eliminate the work of setting the side frame of the hanging frame to the auxiliary guide device installation position and tightening the bolts for attaching the shoe member. To provide an auxiliary guide device for an elevator counterweight that can be easily guided from the center side of a hoistway.

[Summary of the idea]

That is, the auxiliary guide device of the present invention consists of a pair of shoe members attached to the side frames of the hanging frame with the guide rail in between, and at least the shoe member on the hoistway wall side is bolted to the side frames of the hanging frame. It has an L-shaped plate shape, consisting of a mounting plate part that is attached to the mounting plate, and a guide plate part that projects horizontally from the upper or lower end of this mounting plate part and faces the guide rail surface at the side edge. The structure includes a rail abutting plate inserted between the guide rail and the side frame of the hanging frame and facing the side edge of the guide rail. If it is shaped like an L-shaped plate, this shoe member can be fed into the hoistway wall through the gap between the guide rail and the hanging frame side frame, and the rail abutting portion facing the guide rail side edge can be fed into the hoistway. Because it is provided on the center side shoe member, the gap between the guide rail and the hanging frame side frame can be fully utilized before the hoistway center side shoe member is installed, so the hoistway wall side shoe member can be fed through the gap. The installation position can be easily set from the center side of the hoistway, and the bolts for mounting the shaft wall side shoe member can be easily tightened from the center side of the hoistway by inserting a tool through the gap. Furthermore, the shaft center side shoe member can of course be easily attached to the shaft center side.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings.

In FIGS. 4 and 5, reference numeral 1a indicates a hanging frame side frame portion, 2 indicates a weight material, and 4 indicates a guide rail for a counterweight. Reference numerals 15a and 15b are a pair of shoe members attached to the hanging frame side frame portion 1a across the guide rail 4, and the shoe member 15a on the hoistway wall 12 side has a shape as shown in FIG. There is. That is, this hoistway wall side shoe member 15a
is a vertical mounting plate portion 16a that is bolted in contact with the hanging frame side frame portion 1a, and this mounting plate portion 16a.
It is an L-shaped plate consisting of a guide plate part 17a that projects horizontally from the upper end or the lower end and faces the rail surface of the guide rail 4 at the side edge, and the mounting plate part 16a has a shoe member mounting bolt 19a. A mounting hole 18a to be inserted is provided. Also, the center side of the hoistway (the side of the elevator car elevator space)
The shoe member 15b includes a vertical mounting plate part 16b having a mounting hole 18b bolted to the hanging frame side frame part 1a, as shown in FIG. It has an L-shaped plate shape consisting of a guide plate part 17b that protrudes and faces the rail surface of the guide rail 4 at the side edge, and on the side of the mounting plate part 16b on the hoistway wall 12 side,
A rail contact plate part 20 is provided which is inserted between the guide rail 4 and the hanging frame side frame part 1a and faces the side edge of the guide rail 4.
0 is formed to extend from the mounting plate portion 16b. The shoe members 15a and 15b are both manufactured by bending thick steel plates using a press.

That is, this auxiliary guide device includes the hoistway wall side shoe member 15a and the hoistway center side shoe member 1.
5b, and the installation of this auxiliary guide device to the hanging frame side frame portion 1a is as follows: First, install the hoistway wall side shoe member 15a, and then attach the hoistway center side shoe member 15b. It is carried out by. First, the shaft wall side shoe member 15a
To explain the installation of this shoe member 1,
5a to the mounting position is carried out by feeding the shoe member 15a from the center of the hoistway to the wall of the hoistway through the gap between the guide rail 4 and the hanging frame side frame portion 1a. That is, since this show member 15a is an L-shaped plate, the guide plate part 17a (or the mounting plate part 16a) is passed through the gap, and then the show member 15a is rotated 90 degrees and the mounting plate part 16a ( or guide plate part 17a)
By passing it through the gap, it can be sent from the gap to the wall of the hoistway. After the show member 15a is sent to the shaft wall side in this manner, insert your hand through the gap to align the show member 15a to the predetermined mounting position, and then attach the show member 15a to the show member mounting bolt 1.
9a to the hanging frame side frame portion 1a, and after adjusting the distance between the guide plate 17a of this shoe member 15a and the guide rail 4 to a predetermined distance Y, insert a tool from the distance and tighten the bolt 19a. The shoe member 15a may be fixed by tightening. Since the installation of the shaft wall side shoe member 15a is performed before the installation of the shaft center side shoe member 15b, the setting work and bolting work of the shaft wall side shoe member 15a are performed between the guide rail 4 and the hanging frame side frame portion 1a. It is possible to make full use of the gap Z, and therefore each of the above-mentioned operations can be easily performed from the center side of the hoistway. On the other hand, to install the hoistway center side shoe member 15b, set the shoe member 15b at a predetermined mounting position and then tighten the bolts.
9b to the hanging frame side frame portion 1a, and this work can of course be easily performed within a wide space at the center of the hoistway. Note that since this auxiliary guide device is of a split type, the guide plate portion 1 of this shoe member 15b is
It is necessary to adjust the position of the shoe member 15b so that the distance between the guide rail 7b and the guide rail 4 is a predetermined distance Y, but as in this embodiment, the rail abutment provided on the shoe member 15b on the center side of the hoistway Plate part 20
When the tip of the rail abutting plate 20 is brought into contact with the shaft wall side shoe member 15a, the guide plate portion 17 of the hoistway center side shoe member 15b
If the length is set such that the distance between b and the guide rail 4 is a predetermined distance Y (see FIG. 4), there is no need to adjust the position of the hoistway center side shoe member 15b. Further, the distance between the rail abutting plate portion 20 and the guide rail 4 is determined by the distance between the hoistway center side shoe member 15b.
The shims 21 may be inserted between the mounting plate part 16a and the rail abutting plate part 20 and the hanging frame side frame part 1a to adjust the predetermined distance X.

Note that the effect of this auxiliary guide device to prevent the counterweight from coming off the rail is the same as that of the conventional auxiliary guide device explained in the explanation of the background art, so its explanation will be omitted.

FIG. 8 shows another embodiment of the hoistway wall side shoe member 15a.
The steel plate that becomes the mounting plate part 16a and the guide plate part 17
It was manufactured by welding the steel plate a. Further, in the above embodiment, the shoe member 15b on the center side of the hoistway is also formed into an L-shaped plate, but since this shoe member 15b is attached to the center side of the hoistway, the guide rail 4 and the hanging frame side frame portion 1a are connected to each other. There is no need for the shaft center side shoe member 15b to have a shape that can be passed through a gap, and therefore the hoistway center side shoe member 15b can be inserted horizontally into the guide plate portion 17 at an intermediate position of the mounting plate portion 16b.
It may be of any shape, such as one with protruding b.
