Description

The present invention relates to a balancing weight receiving jig and a method of attaching a balancing weight receiving jig used to receive a balancing weight on a guide rail when the work of exchanging the main rope of an elevator is performed.

In the elevator, the main rope is hung on the hoisting machines installed at the upper and lower ends of the hoistway, and the car is hung on one end side of the main rope and the balance weight is hung on the other end side to drive the hoisting machine. By winding up the main rope, the riding basket and the counterweight are configured to move up and down in the hoistway in a fishing bottle style.

In such an elevator, the main rope may be broken if abnormalities such as rust, wire breakage, and wear occur over time, so regular visual inspections and inspections by a dedicated diagnostic device are performed. Then, when it is found that the above-mentioned abnormality exceeds the specified range, the work of replacing the main rope with a new one is carried out. It is necessary to temporarily place the cage and balance weight in the hoistway.

In Patent Document 1, a balancing weight receiving jig is attached to a guide rail that guides the balancing weight so that it can be raised and lowered, and the main rope is replaced with the balancing weight mounted on the balancing weight receiving jig. The technology that was used is described. The balance weight receiving jig described in Patent Document 1 has a back plate that is fastened to the back side of the guide rail using a rail clip and a front side of the guide rail that is fixed to the back plate using a plurality of bolts. It is composed of a support member that protrudes into the support member, and the support member is formed with a notch for penetrating the guide rail.

Further, in Patent Document 2, a car receiving jig is attached to a guide rail that guides the car up and down so that the car can be installed in a state where the car is placed on the car receiving jig. The technology that was used is described. The rider receiving jig described in Patent Document 2 has a back plate that is fastened to the back side of the guide rail using a rail clip and a front side of the guide rail that is fixed to the back plate using a plurality of bolts. It is composed of a support member that protrudes into the support member, and the support member is formed with a notch for penetrating the guide rail. Here, the back plate is formed with a horizontally long elongated hole for passing the bolt of the rail clip, and by laterally moving the bolt in this elongated hole, for several types of guide rails having different width dimensions. The back plate can be fastened.

However, in the prior art described in Patent Document 1, since the position of the rail clip for fastening the back plate, which is a component of the balance weight receiving jig, to the guide rail is uniquely determined, the guide rails having different width dimensions are uniquely determined. There is a problem that several types of balancing weight receiving jigs corresponding to the above are required, and the cost increases accordingly. Further, when the support member arranged on the front side of the guide rail is fixed to the back plate after fastening the back plate to the back side of the guide rail with a rail clip, since the support member is a considerably heavy object, for example, one person. This requires two or more workers to insert bolts into the mounting holes of the support member and the back plate and tighten the nuts while the worker holds the support member at a predetermined height. There is also the problem that it takes time and personnel to install the balancing weight receiving jig.

On the other hand, in the prior art described in Patent Document 2, since a long hole as an adjustment allowance is formed in the back plate which is a constituent member of the car receiving jig, the bolt of the rail clip is laterally formed in the long hole. By moving, one type of car receiving jig can be applied to a plurality of types of guide rails having different width dimensions. However, since the bolt of the rail clip can move in the long hole, if the bolt is misaligned in the long hole when the back plate is fastened to the back side of the guide rail, the back plate will fall off. It will not be possible to fasten it to the guide rail. Therefore, in order to correctly fasten the back plate to a predetermined position on the guide rail, for example, while one worker holds the back plate at a predetermined height, another worker suppresses the rotation of the rail clip. However, the work of two or more people such as tightening the bolts is required.

Therefore, even if the adjustment allowance of the riding car receiving jig described in Patent Document 2 is applied to the balanced weight receiving jig, the riding car receiving jig can be installed in the same manner as in the conventional technique described in Patent Document 1. There is a problem that time is spent with personnel. In particular, due to the layout design of the hoistway, the balance weight is generally placed on the hoistway wall or at the corner of the hoistway, and the space for attaching the balance weight receiving jig to the guide rail becomes narrower accordingly. It is difficult for a single operator to install a counterweight receiving jig on a guide rail having such a narrow space.

The present invention has been made in view of the actual conditions of the prior art, and an object of the present invention is to balance an elevator that can be easily attached to a plurality of types of guide rails having different width dimensions by even one operator. It is an object of the present invention to provide a method for attaching a weight receiving jig and a balancing weight receiving jig.

In order to achieve the above object, a typical balance weight receiving jig for an elevator according to the present invention is connected to a car via a main rope and is connected to a guide rail provided in the hoistway in the vertical direction. A first base body that is fastened and fixed to the guide rail via a rail clip with bolts in an elevator balance weight receiving jig that is placed when the balance weight guided along the guide rail is attached to the guide rail. And the second base body, and the first base body and the second base body have guide grooves extending in the vertical direction at a plurality of positions along the horizontal direction, and the first base body and the first base body. A state in which the first base body and the second base body are positioned in the horizontal direction by inserting the bolt of the rail clip provided on the second base body into the guide groove on the other side from the vertical direction. It is characterized in that it can be attached to the guide rail.

According to the present invention, even one operator can easily attach a counterweight weight receiving jig to a plurality of types of guide rails having different width dimensions at the time of replacement work of the main rope. Issues, configurations, and effects other than those described above will be clarified by the following description of the embodiments.
