REKE-AMI安全帽耐沖擊穿刺測試儀

執(zhí)行標準:

  1. 全自動控制,自動進行動態(tài)信號的采集、數(shù)據(jù)的處理及輸出;
  2. 高度測量簡單,直觀,提高了測試效率和準確度。
REKE-AMI安全帽耐沖擊穿刺測試儀專用于檢測安全帽耐沖擊吸收性能和穿刺性能。安全帽的耐沖擊吸收性能測試中,將測力傳感器剛性的安裝在頭模與底座之間,經(jīng)過預(yù)處理后的安全帽戴在頭模上,然后用質(zhì)量5kg的落錘從1m的高度自由下落沖擊安全帽,由高靈敏度的力值感應(yīng)裝置測出沖擊瞬間的力值,據(jù)此判斷安全帽沖擊吸收性能。安全帽的耐穿刺性能測試中,用3kg的穿刺錐自1m高度自由下落沖擊安全帽,接觸穿刺后,接觸指示器發(fā)出報警指示,判斷安全帽是否穿透。可供檢驗部門和科研單位等使用。

主要用途
REKE-AMI安全帽耐沖擊穿刺測試儀專用于檢測安全帽耐沖擊吸收性能和穿刺性能。安全帽的耐沖擊吸收性能測試中,將測力傳感器剛性的安裝在頭模與底座之間,經(jīng)過預(yù)處理后的安全帽戴在頭模上,然后用質(zhì)量5kg的落錘從1m的高度自由下落沖擊安全帽,由高靈敏度的力值感應(yīng)裝置測出沖擊瞬間的力值,據(jù)此判斷安全帽沖擊吸收性能。安全帽的耐穿刺性能測試中,用3kg的穿刺錐自1m高度自由下落沖擊安全帽,接觸穿刺后,接觸指示器發(fā)出報警指示,判斷安全帽是否穿透。可供檢驗部門和科研單位等使用。
 
REKE-AMI安全帽耐沖刺測試儀,符合國家電力公司《電力安全工器具預(yù)防性試驗規(guī)程》(國電發(fā)[2002]777號)要求,按《規(guī)程》完成安全帽的沖擊試驗和刺穿試驗。

儀器特征
1、儀器實現(xiàn)微電腦全自動控制。采用專用處理系統(tǒng),自動進行動態(tài)信號的采集、數(shù)據(jù)的處理及輸出。儀器具有打印功能(選配)
2、采用德國進口高精度動態(tài)力傳感器,量程20KN,精度1.0%
3、采用無漏磁式吸附結(jié)構(gòu),落錘、穿刺錐自動定位安全帽中心位置
4、測試頭模:專用模具鑄造1號和2號和金屬頭模,符合標準的具體規(guī)定,受到到撞擊后,可以修復(fù),優(yōu)于老標準的木制頭模。
5、整機采用歐標鋁型材,框架式結(jié)構(gòu),穩(wěn)定性更強;電器線路采用內(nèi)置式,結(jié)構(gòu)美觀,具有現(xiàn)代科技感和質(zhì)感。
6、沖擊高度:1000mm±5mm,垂直螺旋手柄調(diào)節(jié)高度。高度調(diào)節(jié)方便,易于控制;高度測量簡單,直觀,提高了測試效率和準確度。
7、落錘和穿刺錘自由替換,操作簡單
8、LED數(shù)字顯示,準確到1N,自動記錄和鎖定沖擊力峰值。
9、防護系統(tǒng):全新設(shè)計四周金屬防護網(wǎng)和安裝鏈接固定方式,底部安裝腳踏開關(guān),大大降低了試驗發(fā)生意外的可能,更進一步提高了試驗操作的安全性。
10、底部裝有水平測試裝置,確保試驗時處于水平,提高試驗精準度。
11、沖擊方式:采用自由落體形式,最真實的模擬實際使用的現(xiàn)場,避免了帶導(dǎo)軌或帶導(dǎo)向落體的進行復(fù)雜的速度補償,保證了測試的準確性。
 
  主要技術(shù)指標:
1、頭模:符合GB/T 2812-2006《安全帽測試方法》標準附錄A的規(guī)定
2、臺架:能夠控制提升、懸掛和釋放沖擊落錘、穿刺錐
3、落錘:沖擊落錘:質(zhì)量為5kg,錘頭為半球形,半徑為48mm,材質(zhì)為45#鋼,外形對稱均勻穿刺錐:質(zhì)量為3kg,穿刺部分:錐角為60°,錐尖半徑0.5mm,長度40mm,直徑28mm,硬度HRC45。
4、測力傳感器:測量范圍0—20KN,頻率相應(yīng)最小5kHz,動態(tài)力傳感器,準確到1N
5、底座:具有抗沖擊強度,能牢固安裝測力傳感器
6、通電顯示裝置:當電路形成閉合回路時,可以發(fā)出報警信號,表示穿刺錐已經(jīng)接觸頭模
7、落錘高度:1000mm±5mm
8、1#、2#鎂鋁合金試驗用頭模各1件,頭模質(zhì)量為5.0kg±0.1kg,其余尺寸及參數(shù)符合GB/T 2812-2006附錄A中的規(guī)定
9、工作電源:AC220V,50Hz
符合標準:GB/T2811-2007 安全帽、GB/T2812-2006 安全帽測試方法
