Description

  The present invention relates to an elevator guide shoe installation adjusting method for adjusting a fixed position of a fixed guide shoe with respect to a counterweight and a car.

  In a conventional anti-vibration rubber type guide shoe for an elevator, the shoe is attached to the frame via the anti-vibration rubber. Then, the bending of the guide rail is absorbed by the bending of the anti-vibration rubber (for example, see Patent Document 1).

JP 52-116550 A

  Conventional anti-vibration rubber guide shoes as described above are more expensive than simple fixed guide shoes that do not have an anti-vibration structure, so they are generally only on the side of the car that requires improved ride comfort. A fixed guide shoe is applied to the counterweight side. On the other hand, since the guide rails for guiding the raising and lowering of the car and the counterweight have a slight warp, the distance between the guide rails is slightly different depending on the position in the vertical direction. For this reason, if the counterweight passes through a place where the distance between the guide rails is narrow when the car is running, the fixed guide shoe will be excessively pressed against the guide rail, causing abnormal wear, or abnormal noise due to stick-slip. Sometimes happened.

  The present invention has been made to solve the above-described problems, and provides an elevator guide shoe installation / adjustment method capable of preventing abnormal wear and abnormal noise even when a fixed guide shoe is used. For the purpose.

  An elevator guide shoe installation / adjustment method according to the present invention includes a pair of guide rails installed in a hoistway, an elevating body which is guided by these guide rails and is moved up and down in the hoistway, and an elevating body by a fixture. An elevator comprising a plurality of fixed guide shoes that are fixed to the guide rail and that engage with the guide rail, the method for adjusting the fixed position of the fixed guide shoe to the lifting body, An adjustment travel step for loosening a fixture for fixing the adjustment target guide shoe, which is at least one of the above, making the adjustment target guide shoe displaceable in the width direction of the lifting body, and traveling the lifting body for a predetermined section; A main fixing step of fixing the adjustment target guide shoe at a position when the step is completed.

  In the elevator guide shoe installation adjusting method according to the present invention, the adjustment target guide shoe is displaceable in the width direction of the lifting body, and the lifting body is moved in a predetermined section so that it is not excessively pressed against the guide rail. Then, the adjustment target guide shoe can be moved slightly, and the adjustment target guide shoe can be fixed at that position, so that abnormal wear and abnormal noise can be prevented even when the fixed type guide shoe is used.

It is sectional drawing which expands and shows the fixed guide shoe of FIG. It is a front view which shows the state which the curvature produced in the counterweight guide rail of FIG. It is a top view which shows the fixed guide shoe in implementation of the guide shoe installation adjustment method by Embodiment 2 of this invention. It is a top view which shows the fixed guide shoe in implementation of the guide shoe installation adjustment method by Embodiment 3 of this invention.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a front view showing a counterweight of an elevator to which a guide shoe installation adjusting method according to Embodiment 1 of the present invention is applied. In the figure, a pair of counterweight guide rails 1 are installed in the hoistway. The counterweight 2 is guided up and down in the hoistway by being guided by the counterweight guide rail 1. The counterweight 2 includes a weight frame 3 and a plurality of weight plates 4 stacked in the weight frame 3.

  The weight frame 3 is provided with a plurality (four in this case) of fixed guide shoes 5 that engage with the counterweight guide rail 1. The fixed guide shoes 5 are disposed at both ends in the width direction of the upper portion of the weight frame 3 and at both ends in the width direction of the lower portion of the weight frame 3. Each fixed guide shoe 5 is fixed to the weight frame 3 by a plurality of bolts 6 (FIG. 4) as a fixing tool.

  One end of a plurality of main ropes 7 as suspension means is connected to the upper part of the weight frame 3. The counterweight 2 is suspended by the main rope 7 at its center of gravity. The other end of the main rope 7 is connected to a car (not shown). An intermediate portion of the main rope 7 is wound around a drive sheave of a hoisting machine (not shown). The car and the counterweight 2 are suspended in the hoistway by the main rope 7 and are raised and lowered by the hoisting machine. A pair of car guide rails (not shown) for guiding the raising and lowering of the car is also installed in the hoistway.

  FIG. 2 is an enlarged cross-sectional view of the fixed guide shoe 5 of FIG. The dimension between the counterweight guide rail 1 and the fixed guide shoe 5 in the width direction of the counterweight 2 (left and right in FIGS. 1 and 2) is a (0 to several mm in the absence of reaction force), If the distance between the sliding surfaces of the right and left fixed guide shoes 5 of the counterweight 2 is b and the distance between the ends of the counterweight guide rails 1 facing each other is c, then if c ≧ b, then smooth Can be expected.

  However, in actuality, as shown in FIG. 3, since the counterweight guide rail 1 has a slight warp, when the counterweight guide rail 1 is warped to the counterweight 2 side, the relationship of b ≧ c Thus, the fixed guide shoe 5 that cannot follow the bending of the counterweight guide rail 1 may cause abnormal wear or stick-slip.

  On the other hand, in the guide shoe installation / adjustment method according to the first embodiment, first, one of the fixed guide shoes 5 is selected as an adjustment target guide shoe. Then, the bolt 6 that fixes the adjustment target guide shoe is loosened to be in a temporarily fixed state, and the adjustment target guide shoe is set to be displaceable in the width direction of the counterweight 2. Thereafter, the counterweight 2 is allowed to travel (travel on the final floor) from a predetermined section, here from the top floor to the bottom floor (or from the bottom floor to the top floor).

  Thus, the process from selecting the adjustment target guide shoe to running on the final floor is defined as an adjustment running step. In the adjustment travel step, the remaining fixed type guide shoes 5 (fixed type guide shoes 5 other than the adjustment target guide shoes) remain fixed to the counterweight 2.

  In such an adjustment travel step, when the counterweight 2 passes through a location where b> c, the fixed guide shoe 5 is slightly moved in the center direction by receiving a reaction force from the counterweight guide rail 1, and b = C. Thereafter, the bolt 6 is tightened at the position when the adjustment traveling step is finished to fix the adjustment target guide shoe (main fixing step).

  The same operation is performed for the remaining fixed guide shoes 5. That is, one of the fixed guide shoes 5 is selected as an adjustment target guide shoe and the adjustment running step and the main fixing step are sequentially performed while changing the adjustment target guide shoe.

  According to such a guide shoe installation and adjustment method, the adjustment target guide shoe can be finely moved to a position where it cannot be excessively pressed against the counterweight guide rail 1, and the adjustment target guide shoe can be fixed at that position. C ≧ b at all locations in the up and down stroke. Therefore, even when the fixed guide shoe 5 is used, abnormal wear and abnormal noise can be prevented.

  Further, since the adjustment traveling step is performed with the fixed guide shoe 5 other than the adjustment target guide shoe fixed, the counterweight 2 can be stably guided by the fixed guide shoe 5 other than the adjustment target guide shoe. The counterweight 2 can be prevented from being shaken or twisted in the front-rear direction.

  When the guide shoe installation / adjustment method described above is performed, the dimension a becomes large at the portion where the counterweight guide rail 1 is warped to the opposite side of the counterweight 2, but the warpage is large (for example, about 2 mm). ) Is sufficiently small with respect to the engagement depth (for example, about 40 mm) of the fixed guide shoe 5 to the counterweight guide rail 1, there is no problem even if the dimension a is somewhat increased.

Embodiment 2. FIG.
Next, FIG. 4 is a plan view showing a fixed guide shoe 5 in which a guide shoe installation adjusting method according to Embodiment 2 of the present invention is being carried out. In the second embodiment, a pair of guide plates (iron plates) 8 serving as displacement regulating members (guide members) are fixed to the weight frame 3 in the adjustment travel step. The guide plate 8 guides the movement of the adjustment target guide shoe in the width direction of the counterweight 2 while restricting the displacement of the adjustment target guide shoe in a direction other than the width direction of the counterweight 2.

  A stopper plate 9 that restricts the movement of the fixed guide shoe 5 in the width direction of the counterweight 2 is also fixed to the weight frame 3. The guide plate 8 and the stopper plate 9 may be temporarily installed by bolting or insertion into a hole, or may be completely fixed by welding or the like. Other configurations and procedures are the same as those in the first embodiment.

  The counterweight guide rail 1 is not only warped in the width direction of the counterweight 2 but may be twisted at the tip of the T-shape. In such a case, if the adjustment travel step is performed simply by loosening the bolt 6, the adjustment target guide shoe follows the counterweight guide rail 1, and the adjustment target guide shoe is twisted. On the other hand, in Embodiment 2, since the guide plate 8 is fixed to the weight frame 3, it is possible to prevent the adjustment target guide shoe from being twisted.

Embodiment 3 FIG.
Next, FIG. 5 is a plan view showing a fixed guide shoe 5 that is performing a guide shoe installation adjusting method according to Embodiment 2 of the present invention. In the third embodiment, a plurality of guide pins 10 are used as the displacement restricting member instead of the guide plate 8 of the second embodiment. Further, a plurality of stopper pins 11 are used instead of the stopper plate 9 of the second embodiment. Other configurations and procedures are the same as those in the second embodiment.

  Even when such a stopper pin 11 is used, it is possible to prevent the adjustment target guide shoe from being twisted as in the second embodiment.

In the first to third embodiments, one of the fixed guide shoes 5 is selected as the adjustment target guide shoe, and the adjustment is sequentially performed. However, if the counterweight 2 can be stably driven, Two or more fixed guide shoes 5 may be selected and adjusted simultaneously.
In the first to third embodiments, the installation adjustment method in the case where the fixed guide shoe 5 is fixed to the counterweight 2 has been described. However, the present invention is also applicable to the case where the fixed guide shoe 5 is fixed to the car. Adjustment method can be applied.
Further, in the first to third embodiments, the entire hoistway is caused to travel to the counterweight 2 in the adjustment travel step. However, for example, when the range in which warpage occurs can be limited, only a part of the hoistway is run. You may let them.
Furthermore, it is preferable that the installation adjusting method of the present invention is applied to all the fixed guide shoes 5. However, even if it is applied only to some of the fixed guide shoes 5, a certain degree of effect can be obtained. it can.
