Description

本発明は、コークス炉等の各種炉内で補修等の作業をするランスを支持する作業台車に関する。   The present invention relates to a work cart that supports a lance that performs repair work in various furnaces such as a coke oven.

従来、作業通路を有するコークス炉等の各種炉内での作業に用いるランスは、長さが５〜１２ｍと長く、炉内へのランスの挿入は、作業通路で先ず人力により実施し、ランスが炉内に挿入され、炉内の支持手段により支持された後、作業通路に作業台を設置し、作業台上で作業員がランスを操作し、作業を行っていた。   Conventionally, a lance used for work in various furnaces such as a coke oven having a work passage is as long as 5 to 12 m, and insertion of the lance into the furnace is first performed manually by the work passage. After being inserted into the furnace and supported by support means in the furnace, a work table was installed in the work passage, and an operator operated the lance on the work table.

また、作業通路を有する炉内作業のためのランス作業台車として、特開平８−２７０２０６号公報に、大型の作業台車に自動制御によりほぼ無人でランス作業をするものが開示されている。
特開平８−２７０２０６号公報 Japanese Laid-Open Patent Application No. 8-270206 discloses a lance work cart for in-furnace work having a work passage, in which a large work cart is subjected to lance work almost automatically by automatic control.
JP-A-8-270206

作業通路を有する炉内でのランス作業は、長いランスを作業通路の進行方向に対して直角方向に人力により炉内に挿入して実施されるため、コークス炉の場合、移動機械が動いているので接触の危険性があり、特に、ガイド側施工時は消火電車が走行しており危険である。その後、作業員がランス作業するための作業台を新たに幅狭の作業通路に設置していたため、作業台の設置に時間がかかり作業効率に問題があった。また、前記特開平８−２７０２０６号公報に開示された大型のランス作業台車は、重量が重いので強度の弱い作業通路では使用できず、格納場所から作業通路への出し入れが困難であり、設備にも多額の費用を必要とするという問題を有するものであった。   Lance work in a furnace having a work passage is carried out by manually inserting a long lance into the furnace in a direction perpendicular to the direction of travel of the work passage. In the case of a coke oven, the moving machine is moving. Therefore, there is a risk of contact, especially during construction on the guide side, fire extinguishing trains are running, which is dangerous. After that, since a work table for workers to perform lance work was newly installed in a narrow work passage, it took time to install the work table and there was a problem in work efficiency. In addition, the large lance work carriage disclosed in Japanese Patent Laid-Open No. 8-270206 is heavy and cannot be used in a work path with low strength, and it is difficult to put it in and out of the work path from a storage place. Also had the problem of requiring a large expense.
