摘  要：介紹利用扣件安裝狀態(tài)檢查儀檢測(cè)扣件彈條離縫值，通過(guò)對(duì)扣件彈條離縫值分析，得出高鐵某區(qū)段內(nèi)扣件離縫值均值和標(biāo)準(zhǔn)差，根據(jù)分析結(jié)果，合理安排扣件復(fù)緊時(shí)機(jī)，并通過(guò)對(duì)可控角度扣件扳手的研發(fā)，控制扣件彈條的扭力矩，使扣件的扣壓力達(dá)到設(shè)計(jì)標(biāo)準(zhǔn)值，更好地服役于鐵路運(yùn)輸。

關(guān)鍵詞：扣件安裝狀態(tài)檢查儀;可控角度扣件扳手;扣壓力;彈條離縫值

Abstract： In this paper， the fastener installation state tester is used to detect the free seam value of the elastic strip of the fastener. Through the analysis of the value of the elastic strip of the fastener， the mean value and standard deviation of the seam value of the fastener in a certain section of the high-speed railway are obtained. According to the results of the analysis， we are supposed to arrange the retightening time of the fastener reasonably， and through the research and development of the controllable angle fastener wrench， control the torque of the fastener elastic strip， achieve the buckle pressure of the fastener to reach the design standard value， and better serve in railway transportation.

Keywords： fastener installation status tester; controllable angle fastener wrench; buckle pressure; elastic strip seam value

鋼軌扣件是鋼軌與下部基礎(chǔ)重要的聯(lián)結(jié)零件，其作用是將鋼軌固定在軌枕上，防止鋼軌的橫縱向移動(dòng)，并保持軌距，扣件還要提供一定的彈性和足夠的強(qiáng)度。（剩余4511字）
