      安山煤礦綜采隊:創新的腳步永不停歇
      類別:故事 作者:沙梁 日期:2019/8/28 字體: 】 閱讀:
      編者按:正是這些在實踐中不斷進行的改革創新,才使得生產效率不斷得以提高。實踐出真知,智慧無極限,創新的腳步永不停歇!

      近年來,安山煤礦綜采隊結合原煤生產過程中遇到的技術難題、設備老化問題、安全生產需要、節支降耗等方面因素積極開展“五小”創新活動,給安全生產工作帶來巨大的效益。

      “小創新”提升檢修新高度
      以往綜采隊膠運巷皮帶頭拉移裝置,在向前拉移張緊滾筒時,后方的三套張緊小車除皮帶穿插鏈接外,再無其他鏈接,導致后方的小車不能隨著張緊滾筒自行移動,而是需要四人同時手工移動,費時又費力,而且安全無保證。
      怎樣才能讓后方小車也能跟著滾筒移動呢?
      帶著這一問題,皮帶檢修班組認真觀察滾筒動力來源,經多次討論后決定在每個小車大梁前后面以及張緊滾筒軸上焊接4.0T鏈環,再用長度一致的六根1.2米長4.0T鐵鏈將張緊裝置與小車相互鏈接。在張緊滾筒拉移時,后邊的小車隨著平行移動。這樣的改造保證了皮帶不跑偏,節省了人力,現在皮帶張緊僅需1人就可操作,即節約了檢修時間,又減少了檢修工勞動強度,創造了安全工作環境。
      今年井下工作面回采期間,有一個月煤機切割電機燒壞三次,當班電工在確認煤機線路正常的情況下,開始摸索到底是什么原因導致電機燒壞?在接下來的生產中發現每次拆卸和安裝期間電機的位置總有偏差!皶粫怯捎陔姍C在出煤期間震動導致電機缺相燒壞?”帶著疑問他們在切割電機的口端上下割兩個眼,上兩道固定螺絲,保證電機在出煤期間減小晃動幅度,就這樣在后期的生產中電機再沒有發生由于震動燒壞的情況,大大提高了安全生產效率。

      多次實驗 精準細致見實效
      工作面頂底板地質條件的變化,容易造成煤機滾筒在割煤時受力不均勻,齒座裂縫,給出煤工作帶來很嚴重的影響。由于礦區不具備大修煤機的條件,將滾筒升井返廠檢修,周期長,費用又高,為了克服這一項大問題,安山煤礦綜采隊煤機檢修組想盡了辦法,先后多次查看圖紙,確定齒座位置,結果焊接完成后在開機過程中,齒座堅持不了兩刀煤,齒座又出現了裂縫,受力大的地方齒座直接掉落。該隊為了早點提高焊接齒座的工藝,成立技術攻關小組,從焊條的使用和齒座焊接位置的摸索,再從焊接期間小細節的把控,經過多次的嘗試,成功破解了齒座的焊接問題,現在該隊焊接出來的齒座克服了煤質硬,厚矸層,頂底板起伏的種種大變化,有力的保障了煤機的穩定運行。
      “齒座裂縫是以前出煤工作的一項難題,通過檢修工藝的改變,現在齒座提高了耐磨性,保障了原煤生產效率!痹撽犼犻L魏大偉說。

      “小發明”提高安全生產效率
      “小惠,啞鈴銷子斷了,更換的時候又費時又費力,你看有什么好的辦法取起來更安全便捷”。
      正在更換齒軌上啞鈴銷子的惠建新聽老師傅蘇正發這么一說,仔細觀察了一下啞鈴銷子眼,每次折斷后都是用螺絲刀砸出來的,不但費時,又很容易就都把螺絲刀砸斷,假如加工個和螺絲刀一樣的鏨子,豈不就能代替螺絲刀了,隨后惠建新下班后就去車間使用廢鋼筋棍給每名三機工加工了200mm長的鏨子,大家有了這個“神器”,再也不用擔心砸斷螺絲刀了。
      隨著工作面的推進,每次拉設備列車期間,壓風自救裝置及其架子需人力向前移動該設備,移動時需要重新收線、鋪線、掛線、還需要四至五名職工人力搬運,增加了職工勞動強度,影響正常檢修工作,給班組帶來極大不便。
      時任檢修班班長杜文偉每次為這事困惑,隨后每天下班后畫圖紙設計,看如何能減輕勞動強度,多次的嘗試后決定將壓風自救裝置用螺絲固定于長1500mm*寬500mm的平板小車上,然后將管路懸掛于小車支撐桿上的掛環內,裝置的相關線路纏繞于滾動圓環上,轉動圓環可實現自動收線功能,在小車底部焊接輪軸并配備四個輪子,利用輪子的滾動作用由一個推動,實現人力搬運。每次拉車可以節約用工人次,節約檢修事跡,同時也降低勞動強度。(白銘武)
