【技术实现步骤摘要】
一种混凝土钻芯机
本技术涉及机械设备,尤其涉及一种混凝土钻芯机。
技术介绍
钻芯法是利用混凝土钻芯机,直接从所需检测的结构或构件上钻取混凝土芯样,按有关规范加工处理后,进行抗压试验,根据芯样的抗压强度推定结构混净土立方体抗压强度的一种局部破损的检测方法,因直观、可靠、准确度高而广泛运用于混凝土结构现场质量检测中。在检测芯样的抗压强度的过程中,需要获得芯样完整光滑,如果芯样本体受到破坏,会影响芯样抗压强度结果,甚至无法达到抗压试验要求。
技术实现思路
针对现有技术的不足,本技术提供一种稳定性好、操作简单、取芯效率高、可直观的读取取芯的厚度、所取芯样完整光滑的混凝土钻芯机。本技术的技术方案为:一种混凝土钻芯机,包括底座、竖架、升降结构、电机、变速箱、钻机、钻头和进水管,其特征在于:所述底座上固定有竖架,所述升降结构活动设置在竖架上,所述变速箱设置在升降结构一侧,所述电机设置在变速箱上方,所述钻机设置在变速箱下方并与升降结构连接,所述钻头设置在钻机下方,所述进水管与钻机连接,所述钻机与钻头的连接部设置有套有外壳的钻杆,所述竖架上设置有垂直测量装置,所述垂直测量装置包括在竖架 ...
