Description

本発明は、ディスクを複数の制動体により挟圧して制動する大容量のエレベータ巻上機の制動体用保守装置に関する。   The present invention relates to a braking body maintenance device for a large-capacity elevator hoisting machine in which a disk is clamped and braked by a plurality of braking bodies.

従来、エレベータ巻上機の保守を行う場合、例えば、軸と一体に回転するディスクを両側から挟圧して制動する制動体に取付けられるライニング交換を行なう場合、機械室天井に設けられた吊り金具等を利用し、チェーンブロック等の揚重機を用いて制動体の脱着を行っていた。   Conventionally, when performing maintenance of an elevator hoisting machine, for example, when performing lining replacement that is attached to a braking body that presses and brakes a disk that rotates integrally with a shaft from both sides, hanging brackets provided on a machine room ceiling, etc. And using a hoist such as a chain block to remove and install the brakes.

しかしながら、大容量のエレベータに備えられる巻上機にあっては、ディスクを複数の制動体により挟圧して制動するものがあり、このような巻上機にあって従来のようにチェーンブロック等の揚重機を用いて順次制動体の脱着を行うと、手間がかかり作業に多大の時間を要するという問題があった。また、揚重機の運搬、取り付け等に労力を要するという問題があった。   However, in a hoisting machine provided in a large-capacity elevator, there is a hoisting machine in which a disc is clamped by a plurality of braking bodies and braked. When the brakes are sequentially attached and detached using a lifting machine, there is a problem that it takes time and much work is required. In addition, there is a problem that labor is required for transportation and installation of the lifting machine.

本発明は、前述した従来技術における実状からなされたもので、その目的は、容易に制動体の脱着を行うことのできるエレベータ巻上機の制動体用保守装置を提供することにある。   The present invention has been made from the above-described prior art, and an object of the present invention is to provide a brake body maintenance device for an elevator hoisting machine in which the brake body can be easily attached and detached.

前記目的を達成するために、本発明の請求項１に係る発明は、軸と一体に回転するディスクを両側から挟圧して制動する複数の制動体を、これらの制動体の両側にそれぞれ設けられた支持ピンを介し所定間隔をあけてペデスタルに固定するエレベータ巻上機の制動体用保守装置において、保守対象となる制動体と、この保守対象となる制動体と隣り合う制動体との各々に、これらの制動体を保持するスタンドを固定するとともに、これらのスタンド間に調整手段を装着し、前記保守対象となる制動体を前記ペデスタルに固定する前記支持ピンの一方を解除して前記調整手段を操作することにより前記保守対象となる制動体を前記ディスクから離隔することを特徴としている。   In order to achieve the above object, the invention according to claim 1 of the present invention is provided with a plurality of braking bodies for braking by pressing a disk rotating integrally with a shaft from both sides, on both sides of these braking bodies. In an elevator hoisting machine brake body maintenance device that is fixed to a pedestal via a support pin at a predetermined interval, a brake body to be maintained and a brake body adjacent to the maintenance body to be maintained Fixing the stands for holding these braking bodies, attaching adjusting means between the stands, and releasing one of the support pins for fixing the braking body to be maintained to the pedestal, thereby adjusting the means Is operated to separate the brake body to be maintained from the disk.

このように構成した本発明の請求項１に係る発明は、保守対象となる制動体の脱着を行う場合、まず、保守対象となる制動体、および保守対象となる制動体と隣り合う制動体の各々に、これらの制動体を保持するスタンドを固定するとともに、スタンド間に調整手段を装着する。この後、保守対象となる制動体をペデスタルに固定する支持ピンの一方を解除し、調整手段を操作することで保守対象となる制動体をディスクから離隔する。次いで、所定の保守作業を行った後、再び調整手段を操作して制動体を装着する。これによって、従来のようにチェーンブロック等の揚重機を用いることなく、容易に制動体の脱着を行うことができる。   In the invention according to the first aspect of the present invention configured as described above, when the brake body to be maintained is detached, first, the brake body to be maintained and the brake body adjacent to the brake body to be maintained are arranged. A stand for holding these braking bodies is fixed to each, and an adjusting means is mounted between the stands. Thereafter, one of the support pins for fixing the brake body to be maintained to the pedestal is released, and the brake body to be maintained is separated from the disk by operating the adjusting means. Next, after performing a predetermined maintenance work, the adjusting means is operated again to mount the braking body. As a result, the braking body can be easily attached and detached without using a lifting machine such as a chain block as in the prior art.

また、本発明の請求項２に係る発明は、前記調整手段を、前記保守対象となる制動体に固定された前記スタンドに回転可能に設けられるリンクと、前記隣り合う制動体に固定された前記スタンドに回転可能に設けられるホルダと、一方が前記リンクに固定されるとともに他方が前記ホルダを介して延長されるねじ棒と、前記ホルダに取付けられ、かつ前記ねじ棒と螺合し、その回転により前記ねじ棒を移動させる調整ナットとで構成したことを特徴としている。   Further, the invention according to claim 2 of the present invention is characterized in that the adjusting means includes a link rotatably provided on the stand fixed to the brake body to be maintained, and the fixed to the adjacent brake body. A holder rotatably provided on the stand; a screw rod that is fixed to the link and one of which is extended through the holder; and is attached to the holder and screwed with the screw rod, and rotates And an adjusting nut for moving the screw rod.

このように構成した本発明の請求項２に係る発明は、調整手段として、保守対象となる制動体側のスタンドにリンクが設けられるとともに、隣り合う制動体側のスタンドにホルダが設けられ、かつねじ棒の一方がリンクに固定されるとともにその他方が調整ナットを介してホルダに移動可能に支持される。この状態で支持ピンの一方を解除し調整ナットを回転することで隣り合う制動体で荷重を受けつつ保守対象となる制動体の脱着を行う。このように、調整ナットを回転することで制動体を移動する構造とするともに、保守対象となる制動体の荷重を隣り合う制動体で受けるという構造とすることにより、容易、かつ確実に制動体の脱着を行うことができる。   In the invention according to claim 2 of the present invention configured as above, a link is provided on the stand on the brake body side to be maintained as an adjustment means, a holder is provided on the stand on the adjacent brake body side, and the screw rod One is fixed to the link, and the other is movably supported by the holder via the adjusting nut. In this state, one of the support pins is released and the adjustment nut is rotated, so that the brake body to be maintained is detached while receiving a load on the adjacent brake body. As described above, the brake body is moved by rotating the adjusting nut, and the structure is such that the load of the brake body to be maintained is received by the adjacent brake body. Can be desorbed.

本発明によれば、チェーンブロック等の揚重機を用いることなく、容易に制動体の脱着を簡単に行うことができ、これによって、保守作業に要する時間および労力の低減を図ることができる。   According to the present invention, it is possible to easily attach and detach the brake body without using a lifting machine such as a chain block, thereby reducing the time and labor required for maintenance work.
