North side of the tank 4 old rope cut by gas cutting, and then to the north side of the tank 4 with the corresponding old new rope tied solid and well-head side of
29、 the South can take temporary work platform. Starting winch, hook cage South decentralization, while the remaining out of the old rope, after the removal of temporary work platform. (9) transfer to justice. After all, no problem, winch test run, commissioning a variety of protection. 3、Construction
30、Notes (1) signal is the key to the construction, we must set up the command center, put to justice and enhancing the signal to separate the signals, at least to prepare two sets of signals, and winch drivers, put ropes and other staff to participate in the construction clearly. (2) the length of boa
31、rd and hand chain hoist, and early tests, such as appliances, and construction must be firmly card. (3) in the interception of a new rope should be based on precise calculation of the amount in advance from a good length of rope, new rope can not be truncated, otherwise, would be lost by the wayside
32、, causing a greater loss. (4) use of specialized wire rope and lifting and hand chain hoist beam intensity calibration must be carried out together into the measures. 4、Conclusion (1) of this method with the traditional solid car with rope method, the construction time is short. Cao coal for the use
33、 of this method were used rope l9.5h, save time 1 / 3 polyunsaturated. (2) low-cost construction. This method saves the cost of steady rental cars, a construction can save about 25,000 yuan. (3) high degree of safety, reduce labor intensity. Minimization of this method in the construction of the sha
34、ft to raise the safety factor, without a fixed rope roller, just the direction of the rope can be placed, the short preparation time.中文翻译 多绳摩擦式提升机换绳新工艺多绳摩擦式提升机在更换钢丝绳时,通常使用4部固定稳车旧绳带新绳,工艺复杂,施工人员多在井口和井筒作业,危险性较大,而且矿井停产时间较长,因此如何在更换此类提升机主钢丝绳中更加安全、省时,一直是人们研究的目标.1、 施工准备(1)提前对备用楔型吊挂装置进行探伤,对新钢丝绳进行试验,符合煤矿安全规程第
35、402条的相关规定后,测量尺寸,截成四段分别缠在四只绳滚子上,按捻向要求放于井架的北侧,并固定好。 (2)在井架北钩横梁合适位置固定四个导向轮,以便钢丝绳能够顺利运动。(3)调整自动平整油缸杠杆的伸出量,首先使南钩自动平衡油缸杠杆的伸出量一致后,关闭南钩各自动平衡油缸的分截止阀,运行1天后,再量取南北两钩各油缸杠杆的伸出量,并记录好,作为截绳的依据。(4)准备好卡绳用的长、短板卡,长板卡需要3副,短板卡需要8副。(5)准备好充足的照明和可靠的信号设施以及棕绳、铁丝、木板、工字钢以及常用工具等,并检查其是否合格。2、 施工步骤(1)自上而下清扫平台、井架及井筒,拆除滚筒护板。井口以上用旧绳带新绳
36、,具体方法为: 将南罐停在罐顶与井口平的位置;在井口北罐侧搭工作平台,将新钢丝绳穿过井塔北墙窗及四个导向轮,并与北罐四根旧绳分别用长3m的小棕绳捆绑在一起,新绳头处连续捆绑三道(新绳在旧绳西侧)。具体捆绑方法是:先用3m长麻绳的其中1m密集缠绕新绳,再用剩余的麻绳在原来缠绕新绳的位置将新、旧绳捆绑在一起,绑完后用水将麻绳浸透(捆绑前小棕绳稍湿)。下放南罐同时放新绳,用与上述同样的方法自第一道棕绳起每间隔10m将新绳与旧绳捆绑牢固,当新钢丝绳绳头到达南罐侧,并与井口以上第一道钢梁平齐时停车,拆除井口北罐工作平台。在井塔四层平台上,用专用板卡在北罐侧将四根绳卡牢,以防止新绳回窜,然后,割掉所有捆绑
37、的麻绳,使新绳与旧绳分开。在井塔五层,将南罐侧新绳用吊绳板卡卡牢,用行车将四根新绳吊起适当高度,以主滚筒不能带动新绳转动为准,然后用人力将四根新绳托至二层平台。 (2)南罐新钢丝绳上钩头。将南罐侧四根绳头分别与四个备用楔形吊挂装置连接牢固;将新、旧钢丝绳的吊挂装置对齐后,用麻绳牢固地捆绑在一起。先将二层上的打压泵与南罐液压自动平衡油缸连通管连好后,打开总截门少许,将油缸内的油全部放入打压泵内,再将南钩液压自动平衡油缸联通管拆除,并放到一指定地点。最后缓慢下放南钩罐笼,拉紧多余的新绳。 (3)井筒带新钢丝绳。拆除五层吊绳的长板卡子及四层防回窜板卡,并将四根新绳分别放在与其对应的旧钢丝绳槽西侧合适
38、位置。在井塔三层平台上,将南罐侧新、旧钢丝绳用一付长板卡子卡牢,然后在长板卡子的上下各卡4付小板卡。提升机用低频速度下放南罐,同时,四个绳滚子以相应的速度放绳;此时,在井塔三层平台南罐侧,自第一付长板卡子起每隔6m捆绑一道麻绳(方法同上述)并及时浇水浸透,每隔50m分别卡四付小板卡子。 当北罐接近井口二层平台时停车,带绳结束。 (4)更换南钩罐笼四个楔型吊挂装置。首先在井塔四层,南钩钢丝绳东西方向并排放两根20号工字钢,在其上面放四个卡绳器,将南钩四根旧绳卡牢。用两只20t葫芦配合采煤机锚链将北钩罐笼吊住;用两只10t葫芦,将南罐吊起适当的高度,先更换东侧两只吊挂装置,具体方法是:用125mm
39、钢绳套子及It葫芦将液压自动平衡装置伸缩体吊住,依次拆除东侧两只原楔型吊型挂装置。然后,首先安装东起第二只新楔型吊挂装置,再安装东起第一只新楔型吊挂置。更换西侧两只楔型吊挂装置,更换完毕,用麻绳将新、旧钢丝绳吊挂装置对应牢固地捆绑在一起。 (5)在二层平台上截新钢丝绳,并将新钢丝绳与备用楔形吊挂装置连接好。 (6)更换北钩罐笼四个楔型吊挂装置。先将二层上的打压泵与北罐液压自动平衡油缸连通管连好后,打开总截门少许,将油缸内的油全部放入打压泵内,再将北钩液压自动平衡油缸联通管拆除,放好。拉两只20t葫芦将北钩罐笼水平吊起适当高度,按照由东至西的顺序逐步更换北钩楔型吊挂装置,更换完毕,割除旧绳,并拆
40、除工作平台。 (7)倒绳槽。在井塔四层用长板卡子将北钩侧的四根新绳及四根旧绳卡牢。 用125mm钢丝绳绳套子及行车,将新、旧钢丝绳吊起,使新、旧钢丝绳脱离主导轮,从东侧起,依次将旧绳从主导轮、导向轮绳槽中取出,并将新绳依次放入绳槽,将旧绳放在主导轮或导向轮的衬垫上(绳槽东侧)。拆除井塔四层卡绳用板卡子。(8)回收旧钢丝绳。 同时松吊北钩罐笼的两只20t葫芦,将罐笼落下直至新钢丝绳受力,拆除起吊用具,并将四根旧绳头与其对应的新钢丝绳捆绑在一起。 井下组织施工人员拆除南钩罐笼起吊用具和工作平台。 开动绞车适当距离,拆除卡绳器及工字钢。检查无问题后,开始用低频下放北钩罐笼,用人力将旧绳通过井1:3的
41、四个导向轮拖至对应的绳滚子上,同时将新、旧绳上的卡子和棕绳去除。 当南钩罐顶到达井1:3合适位置时停车,用气割将旧钢丝绳在钩头以上截断,拖至不妨碍施工的地方。 在井1:3合适位置。将北罐侧四根旧绳用气割截断,然后,将北罐侧的四根旧绳头与其对应的新钢丝绳牢固的捆绑在一起,并在井口南罐侧搭临时工作平台。 开动绞车,下放南钩罐笼,同时将剩余的旧绳拖出,完毕后,拆除临时工作平台。(9)调绳。一切无问题后,绞车试运行、调试各种保护。 3、 施工中的注意事项(1)信号是施工的关键,必须设立指挥中心,放绳信号与提升信号要分开,至少准备两套信号,并与绞车司机、放绳人员及其他参加施工人员交代清楚。 (2)长短板卡和卡绳器以及手拉葫芦等用具必须提前试验好,施工中必须卡牢。 (3)在截取新绳时,必须根据事前的计算精确量取好绳的长度,千万不可将新绳截短,否则,将功亏一篑,造成较大损失。(4)对专门起吊用的钢丝绳和工字钢以及手拉葫芦必须进行强度校验,一并写入措施中。4、结论 (1)本方法与传统的稳车带绳法相比,施工时间短。曹庄煤矿使用本方法换绳共使用l95h,节省时间13多。 (2)施工费用低。本方法节省了稳车的租赁费用,一次施工可以节约25万元左右。 (3)安全程度高,劳动强度降低。本方法最大限度减少了在井筒中的施工,提高了安全系数,钢丝绳滚子无需固定,只需按出绳方向放置即可,准备时间短。
