錘(chui)頭(tou)中心到(dao)鉸(jiao)接點中心距離(li):1.5M

首(shou)先要把錘(chui)(chui)擊(ji)(ji)試(shi)驗機底(di)座(zuo)與地(di)面(mian)用(yong)膨脹螺絲固定好，以(yi)免在(zai)錘(chui)(chui)擊(ji)(ji)過程中發生跳動和位(wei)(wei)移，試(shi)件應水平放(fang)置(zhi)(zhi)，軸(zhou)線與擺(bai)臂(bei)垂直，錘(chui)(chui)擊(ji)(ji)點(dian)(dian)(dian)處與錘(chui)(chui)頭(tou)軸(zhou)線貼合，錘(chui)(chui)頭(tou)與試(shi)件接觸時(shi)，擺(bai)臂(bei)處于水平位(wei)(wei)置(zhi)(zhi)，錘(chui)(chui)擊(ji)(ji)點(dian)(dian)(dian)下方應墊(dian)實，襯墊(dian)長(chang)度不小于200MM。其次錘(chui)(chui)擊(ji)(ji)點(dian)(dian)(dian)選擇，每根電桿(gan)(gan)選擇3 個(ge)錘(chui)(chui)擊(ji)(ji)點(dian)(dian)(dian)分別進行試(shi)驗，個(ge)錘(chui)(chui)擊(ji)(ji)點(dian)(dian)(dian)在(zai)距大端1M 處;第二個(ge)錘(chui)(chui)擊(ji)(ji)點(dian)(dian)(dian)在(zai)距大端2M 處，并將電桿(gan)(gan)旋轉120°;第三個(ge)錘(chui)(chui)擊(ji)(ji)點(dian)(dian)(dian)在(zai)距大端3M。

混凝土電桿錘擊試驗機

符合《T/CEC143-2017超高性(xing)能(neng)(neng)混凝土電桿》標(biao)準中(zhong)電桿抗(kang)撞擊(ji)性(xing)能(neng)(neng)要求，是檢驗電桿在運輸(shu)、裝卸、安裝及使(shi)用過程中(zhong)發(fa)生的(de)(de)跌(die)落(luo)、撞擊(ji)及刮碰等(deng)荷載作用的(de)(de)抵抗(kang)能(neng)(neng)力。適用于(yu)電力、通信及接觸網架空(kong)線(xian)路的(de)(de)電桿、照明(ming)支柱(zhu)和(he)信號機(ji)柱(zhu)等(deng)，壁厚小于(yu)30MM 電桿的(de)(de)抗(kang)撞擊(ji)性(xing)能(neng)(neng)試驗。

錘頭(tou)與(yu)試件接觸端面:宜(yi)為(wei)邊(bian)長65MM 正方形(xing)平面

錘頭質量:宜為8.16KG

錘(chui)頭質量偏(pian)差(cha):士(shi)50G、幾何尺寸偏(pian)差(cha)為士(shi)2MM擺(bai)臂:宜(yi)為中40、壁(bi)厚3.5MM 的鋼(gang)管

錘頭中心到鉸接點中心距(ju)離:1.5M

首先要把錘(chui)(chui)(chui)(chui)擊(ji)(ji)(ji)試驗機底座與地面用(yong)膨脹螺(luo)絲固定好，以免在(zai)(zai)錘(chui)(chui)(chui)(chui)擊(ji)(ji)(ji)過程中發生跳動(dong)和位(wei)移，試件(jian)應水(shui)平(ping)放置，軸(zhou)線與擺(bai)臂(bei)垂直，錘(chui)(chui)(chui)(chui)擊(ji)(ji)(ji)點(dian)(dian)(dian)處與錘(chui)(chui)(chui)(chui)頭(tou)軸(zhou)線貼合(he)，錘(chui)(chui)(chui)(chui)頭(tou)與試件(jian)接觸時，擺(bai)臂(bei)處于水(shui)平(ping)位(wei)置，錘(chui)(chui)(chui)(chui)擊(ji)(ji)(ji)點(dian)(dian)(dian)下方應墊(dian)實，襯墊(dian)長度不(bu)小于200MM。其次錘(chui)(chui)(chui)(chui)擊(ji)(ji)(ji)點(dian)(dian)(dian)選(xuan)擇，每根電桿選(xuan)擇3 個錘(chui)(chui)(chui)(chui)擊(ji)(ji)(ji)點(dian)(dian)(dian)分別進(jin)行試驗，個錘(chui)(chui)(chui)(chui)擊(ji)(ji)(ji)點(dian)(dian)(dian)在(zai)(zai)距大(da)端(duan)1M 處;第(di)二(er)個錘(chui)(chui)(chui)(chui)擊(ji)(ji)(ji)點(dian)(dian)(dian)在(zai)(zai)距大(da)端(duan)2M 處，并將電桿旋轉120°;第(di)三個錘(chui)(chui)(chui)(chui)擊(ji)(ji)(ji)點(dian)(dian)(dian)在(zai)(zai)距大(da)端(duan)3M。
