Description

【０００１】
【発明の属する技術分野】
本発明は、主に火力発電所におけるボイラに石炭を定量供給する給炭機において、狭い保守スペースでも設置することができる給炭機の構造に関する。
【０００２】
【従来技術】
従来のものは、円筒形容器の内部の両側にレールを取り付け、計量コンベアフレームに車輪を設けて該レールの上に載せて、物品の搬送方向とは反対の方向にベルトコンベアフレームごと全体を引き出す構造のものが、特開昭５８−５９１１１号にて紹介されている。特開昭５８−５９１１１号では、第１図に示すように円筒形容器１の内部両側にレール７が固定して設けられており、コンベアフレーム５に設けられたローラ６が該レール７に載置された構造になっている。そして第３図に示すようにベルトコンベア４の搬送方向とは反対の方向に、ベルトコンベア全体を該円筒形容器から引き出して、各部の保守点検を行うものである。
【０００３】
保守点検にはベルトコンベアの消耗品である無端ベルトの交換や駆動プーリのゴムラギングの摩耗等による修理交換などがあるが、中でもベルトコンベアのベルトの取り替えは多大の労力を伴う作業である。この方法では、ベルトコンベア全体を円筒形容器から引き出しているため、円筒形容器外にあり無端ベルトの交換は容易にできる。しかし、このようにベルトコンベア全体を後方に引き出すには、円筒形容器の後方に該円筒形容器とほぼ同等の長さのスペースが必要となる。
【０００４】
一方コンベア直取り付け方式のものもある。コンベア直取り付け方式というのは、円筒形容器の外側面に駆動プーリの軸受けが直接取り付けられた構造であり、駆動プーリと駆動プーリの軸とは一体になっており、その軸長は円筒形容器の直径よりも大きくなっていて、円筒形容器の外側に突出した構造であり、その外側に駆動部が設けられ上記の軸を介して駆動されている。このような構造ではベルトを取り外すとき、先ず駆動部を外し円筒形容器の側面の軸受けを外し、駆動プーリを円筒形容器の側面へ引き出す、そして、無端ベルトとテールプーリとを一緒に円筒形容器の後方から取り出している。またベルトコンベアの中間に位置するキャリアーローラ類は容器内に取り付けられているため、円筒形容器の側面に設けた点検用扉から側面に取り出している。ところが駆動プーリを円筒形容器の引き出すには、駆動プーリの軸長が円筒形容器の直径より長いため、該円筒形容器の側面に該円筒形容器の直径よりも大きいスペースが必要となる。
【０００５】
【発明が解決しようとする課題】
つまり給炭機本体の２倍以上の保守スペースがなければならず、複数の給炭機を横に並べて配置する場合、該給炭機と後段の設備とが上下方向に一対一の関係にあるレイアウトでは後段にまで余分なスペースを与えることになっている。このように従来の給炭機では、給炭機の後方にも、また側方にもほぼ給炭機と同等もしくはそれ以上の保守点検用のスペースが必要となっていた。そこで本発明は、従来からの課題を解決すべく、設置スペースが狭くても保守が可能な給炭機を提供することにある。
【０００６】
【課題を解決するための手段】
計量用ベルトコンベアを円筒形容器内に備えた給炭機において、上記計量用ベルトコンベアの搬送方向の後方近傍にあって、上記円筒形容器の後端壁部に計量用ベルトコンベアの少なくとも駆動プーリと無端ベルトとを取り出すための出入り口を設け、上記駆動プーリと上記無端ベルトとを支持して上記出入り口を通り円筒形容器外に搬出するためのガイドレールを着脱自在に設け、更に上記円筒形容器の内部側壁には上記ガイドレールを取り付けるためのボスを複数個設けた構造とした。上記円筒形容器の両側壁には複数の点検用扉を設けたので、キャリヤーローラ等はここから取り出すことが望ましい、上記計量用ベルトコンベアの駆動プーリの駆動軸が上記駆動プーリのハブ両端面にて分離可能にしたことも特徴であり、従来のように長い駆動軸を円筒形容器の側方に引き出す必要がない。上記駆動軸を枢支する軸受けは円筒形容器の側壁に軸受け取り付けフランジと共に着脱可能に設けた、そして上記円筒形容器の側壁には上記フランジ取り付け窓を設けて、この窓から駆動プーリのハブ両端面に取り付けられた駆動軸を分離する作業をするようにした。
【０００７】
【発明の実施の形態】
以下、図示した実施例について説明をする。図１は本発明の給炭機の側面図である。１ａは駆動プーリ、１ｂはテールプーリ（従動側プーリ）、２は円筒形容器、１０は搬送用無端ベルト（以下ベルトという）、１１は円筒形容器の後端壁部の出入り口、１２は供給口、１３は排出口、１４は容器内清掃コンベア、１５はキャリヤーローラ、１６は計量キャリヤである。図２は図１のＡ−Ａ矢視図であって円筒形容器の側面に２２の駆動部が設けられている。図３は円筒形容器の外観図である。図４は図３を上から見た図である。円筒形容器２の両側に駆動プーリの駆動軸が貫通しており、それぞれ軸受け取り付け用フランジ４および軸受けユニット５が設けられている。また円筒形容器の両側には点検用扉２０，２１がそれぞれ設けられている。１１−１は円筒形容器の後端壁部出入り口の扉である。本発明の給炭機においては、円筒形容器内に設けられているベルトコンベアにはコンベア用フレームを設けていない、駆動プーリやテールプーリ各キャリヤ類が全て円筒容器内に直接取り付けられており、構成を簡素化し内部の清掃などを容易にした構造である。
【０００８】
このような構造の給炭機は概略次のように動作する。今１２の供給口から物品、例えば石炭が供給されると、該石炭は１０のベルトの上に到達し、ベルトの搬送方向に従って所定の層厚に積載されて搬送される。１５、１５のキャリヤの間にある１６のキャリヤは計量キャリヤといって、ベルト上に積載された物品の重さを計るキャリヤである。１５，１５のキャリヤ間のベルト上に分布する物品の重量が、ベルトの撓みに従ってこのキャリヤに加わり、計量キャリヤに接続されているロードセル１６−１にて重量が検知される。そしてこのコンベアによって搬送される物品の搬送量は、前記検知された重量値とコンベアの搬送速度との積により得られるようになっている。
【０００９】
次に円筒形容器内に設置したベルトコンベアのベルトの取り替えについて図５、図６および図７と併せて説明する。図５は駆動プーリにおける駆動軸からの分離（着脱）を示す図である。３は駆動プーリのハブ、４は円筒形容器の側面に設けられた軸受け取り付け用フランジ、５は軸受けユニット、６は駆動軸、７，８，９は各取り付けボルトである。図６は円筒形容器の駆動プーリ付近の横断面図である。１７は円筒形容器の内面に設けられたガイドレール取り付け用ボス、１８はガイドレール、１９はガイドレール取り付け用ボルトである。図７は本発明における円筒形容器からベルトを取り出す直前の状態を示す図である。
【００１０】
一方テールプーリ（従動プーリ）の詳細については記述していないが、テールプーリは本来円筒形容器の中に組み込まれており、その軸長は円筒形容器の径よりも短いために、図１の１Ｃに示すようにベルトの張力調整装置の部分を取り外せばベルトと一緒に円筒形容器の後方より取り出すことができる。
【００１１】
本発明によるとベルトの取り替えは、まず、円筒形容器２の内面に設けたボス１７にガイドレール１８を取り付ける、図６参照、本発明ではガイドレール１８は通常取り外しているのでベルトの取り替え時のみ取り付ける。そして円筒形容器２の側面に設けられたベルトコンベアの駆動部２２を取り外す、次に図５に示すように７のボルトを外し、軸受け取り付け用フランジ４を外す、このフランジを外すと駆動プーリの端面ハブが見える、該フランジが取り付けられている窓の大きさは駆動プーリの外径より大きくすることが望ましい。駆動軸６の取り付けボルト９を緩めて駆動プーリから駆動軸を分離する。そして次にキャリヤを取り外すが、全てのキャリヤは円筒形容器の側面にある点検用扉２０，２１から円筒形容器外に取り出すことができる。この状態になると、駆動プーリ１ａとテールプーリ１ｂがベルトの内側に位置して、図７に示すようになり、ガイドレール１８によって支持された状態となって、ガイドレール１８上を矢印２３，２３のように転がして、円筒形容器の後方（矢印２４）に取り出すことができる。
【００１２】
【発明の効果】
コンベアの消耗品であるベルトを交換する場合や、駆動プーリのゴムラギングの摩耗による修理のためにコンベアを引き出す方式のものでは、円筒形容器の後方に円筒形容器の全長とほぼ同じ長さのスペースが必要であった、また円筒形容器の側方においても駆動プーリ軸を引き出すためのスペースが必要であったが、本発明では、駆動プーリの駆動軸を駆動プーリのハブ面で駆動軸と着脱自在にしたので、駆動軸を取り外せば、駆動プーリ、ベルト、テールプーリのみの状態になり、給炭機後方から容易に円筒形容器の外に取り出すことができる。従って給炭機周辺においては、従来の半分以下のスペースで保守ができるという効果のほか、給炭機を設置するレイアウトにおいては前後装置などを含めて建家全体の省スペース化が可能となるなど顕著な効果を奏する。

Maintenance inspection includes replacement of an endless belt, which is a consumable part of the belt conveyor, and repair replacement due to wear of rubber lagging of the drive pulley, etc. Among them, replacement of the belt of the belt conveyor is an operation that involves a great deal of labor. In this method, since the entire belt conveyor is pulled out from the cylindrical container, the endless belt can be easily replaced because it is outside the cylindrical container. However, in order to pull out the entire belt conveyor to the rear in this way, a space having a length substantially equal to that of the cylindrical container is required behind the cylindrical container.
[0004]
On the other hand, there is also a conveyor direct attachment type. The conveyor direct attachment system is a structure in which the bearing of the drive pulley is directly attached to the outer surface of the cylindrical container, and the drive pulley and the shaft of the drive pulley are integrated, and the axial length is the cylindrical container. It has a structure that is larger than the diameter of the cylindrical container and protrudes to the outside of the cylindrical container. In such a structure, when removing the belt, first, the drive unit is removed, the bearing on the side surface of the cylindrical container is removed, the drive pulley is pulled out to the side surface of the cylindrical container, and the endless belt and the tail pulley are joined together in the cylindrical container. It is taken out from the back. Further, since the carrier rollers located in the middle of the belt conveyor are mounted in the container, they are taken out from the inspection door provided on the side surface of the cylindrical container to the side surface. However, in order to pull out the drive pulley from the cylindrical container, since the axial length of the drive pulley is longer than the diameter of the cylindrical container, a space larger than the diameter of the cylindrical container is required on the side surface of the cylindrical container.
[0005]
[Problems to be solved by the invention]
That is, there must be more than twice the maintenance space of the main body of the coal feeder, and when a plurality of coal feeders are arranged side by side, the feeder and the downstream equipment are in a one-to-one relationship in the vertical direction. In the layout, an extra space is given to the subsequent stage. As described above, in the conventional coal feeder, a space for maintenance and inspection that is substantially equal to or more than that of the coal feeder is required both on the rear side and on the side of the coal feeder. Therefore, the present invention is to provide a coal feeder that can be maintained even if the installation space is small, in order to solve the conventional problems.
[0006]
[Means for Solving the Problems]
