    交通與運輸

      滑板運輸在支架等大型綜機設備倒面安裝中有其便捷、易操作的優點,滑板運輸因直接跳過了軌道運輸支架部件中的整體支架裝車、拆解、組裝、下道等環節,極大降低了安撤環節及安撤成本。但是滑板鋪設的質量要求、滑板運輸的工藝要求等缺乏行業統一標準、規范,本文以兗礦集團興隆莊煤礦B4324工作面支架倒面安裝B4326工作面為例,研討滑板運輸在大型綜機設備倒面安裝中的應用。

      1倒面安裝工作面布置概述

      B4324、B4326工作面均位于兗礦集團興隆莊煤礦的西翼四采區下部,北西部為切眼與4324下順槽相鄰,南西部與4326停采線相鄰,南東為設計停采線與B4326運煤巷相鄰,兩個工作面推進長度分別為280m、310m,B4324工作面設計煤炭儲量為31萬t,B4326工作面設計煤炭儲量為42萬t,工作面內有4326新。

      二聯、4326撤除巷及四采下部運煤巷等老巷道,有DF1、DF2、程家莊3#三條斷層在工作面推進過程中不斷揭露。B4324工作面設計安裝116組支架,B4326工作面設計安裝120組支架,兩個工作面的詳細支架布置情況見表一。兩工作面均以四采下部集軌巷作為軌道順槽,兩工作面均與四采下部集軌巷成33°夾角,即工作面每推進2.2m(約3排)撤除1組支架,撤除支架經四采下部集軌巷運輸至B4326安裝巷門口,然后運輸至B4326切眼安裝。

      2倒面安裝動力系統的選擇

      2.1對拉絞車選擇的必要性

      支架底座箱對滑板的摩擦因數在0.1-0.2之間,計算可得支架在滑板上勻速直線運動的坡度在5°-11°之間,由于四采下部集軌巷集軌巷平均坡度為10°且最大坡度為16°所以支架在四采下部集運巷運輸時必須設置對拉絞車整體松拉支架。

      2.2整體對拉絞車的選擇

      隨著工作面回采的不斷推進,在機尾直接布置松整體支架絞車需要頻繁挪位置,安裝較為困難,所以制定了在B4326切眼口以下布置兩部絞車,其中一部絞車配合鐵滑車松留支架,一部絞車直接拖拽支架。因從B4324工作面邊采邊撤開始到B4326安裝巷面口約250m,所以松留支架的絞車纏繩量應不低于550m,最終綜合現場四采下部集運巷集運巷運輸長度、坡度、絞車容繩量等因素考慮,最終選擇一部JSDB-19回柱機纏28mm鋼絲繩600m、一部JSDB-13回柱機纏24mm鋼絲繩240m,作為四采下部集運巷松拉配合運輸支架的兩部動力。

      3滑板運輸特殊設計

      3.1整體方案設計

      從B4324邊采邊撤開始至B4326切眼機頭共約250m在四采下部集軌巷共布置166塊滑板(約250米),并在四采下部集軌巷與B4326門口布置拐彎滑板1組,使用一部JSDB-19與一部JSDB-13回柱機送拉配合,保證整體支架在四采下部集軌巷的運輸安全,使用安裝兩部JM-14回柱機作為對拉絞車,將整體支架在拐彎滑板上運輸B4326機尾位置安裝。

      3.2對拉絞車特殊要求

      由于雙速回柱絞車在松拉過程中隨著滾筒纏繩高度變化,滾筒鋼絲繩的線速度也發生變化,如何保證松留回柱機的線速度一直大于拖拉回柱機的線速度是滑板運輸的關鍵。JSDB-19回柱機滾筒每圈纏繩為:770mm÷26mm=29圈,設計容繩量500m,當支架在坡度頂時滾筒纏繩為7層,滾筒線速度為11.1m/min,隨著支架的運輸滾筒容繩量逐漸減小,同理可算得當支架到達B4326安裝巷門口時,滾筒線速度為9.3m/min;通過調整JSDB-13回柱絞車的初始滾筒纏繩量,同理可推算得JSDB-13的最大和最小線速度分別為6.7m/min和8.9m/min,JSDB-19的鋼絲繩最小運輸速度大于JSDB-13的最大鋼絲繩運行速度,符合對拉絞車的設計要求。

      3.3對絞車鋼絲繩選擇的要求

      拖移所用絞車的鋼絲繩必須與絞車相匹配,鋼絲繩最小破斷拉力與絞車最大牽引力之比不小于1.5,F鋼絲繩/F絞車=528/320=1.65>1.5,符合要求。調整拖拉JSDB-13回柱機的開關整定值,保證支架在滑板運輸的安全性。正常在用的JSDB-13回柱機開關整定值為22A,為保證回柱機在滑板上拖拉支架的安全性,將開關的整定值整定為16A,人為將JSDB-13回柱機的最大拉力下調1/4,保證一旦出現意外情況時JSDB-13回柱機能快速斷電。

      4滑板鋪設的質量要求

      該倒面安裝系統中使用的滑板為兗礦大陸公司設計的1.5m長、2m寬的自插銷式滑板,每塊滑板重約450kg,使用M30的銷軸固定。

      1)滑板鋪設時,滑板聯接處平整度的要求。根據運輸支架的現場經驗,滑板間隙長度不大于8mm,滑板鉸接處坡度為不大于±1°,保證支架在滑板運行至接頭處時不出現卡阻。

      2)滑板鋪設時,對滑板鉸接處直線型的要求。根據運輸支架的實踐,任意15m內滑板槽幫邊線的角度差值不能超過1.5°。防止支架運輸過程中支架偏移造成滑板外槽幫對支架底座箱的卡阻。

      3)對滑板穩定性的要求。該滑板在槽幫上設計有兩個Φ28的孔,方便滑板兩側打錨桿固定滑板。由于該面支架下滑的坡度較大,規定每15m即10組支架打兩組地錨固定滑板,保證支架運行時滑板穩定。滑板聯接部位左右變形量不超過10mm、上下不超過50mm、擋沿變形量不大于20mm。滑板彎曲橫向變形量不大于20mm、順向變形量不大于15mm。

      4)使用過程中對滑板的維護措施。安排專人每天對支架運輸滑板的鉸接平整度、直線度、穩定型進行檢查,尤其對固定地錨必須每班檢查松緊度,并做好記錄,保證支架運輸的安全、可靠。
