Description

一种用于地下管线探测的动力触探装置 技术领域
本实用新型涉及动力触探装置技术领域，具体为一种用于地下管线探测的动力触探装置。
背景技术
动力触探试验是岩土工程勘察常用的一种原位测试方法。该方法是利用一定的落锤质量，将一定尺寸、一定形状的探头打入土中，根据打入的难度，即贯入锤击数，判定土层名称及其工程性质，具有勘察与测试的双重性能。根据穿心锤质量和提升高度的不同，国内常用的落锤三种质量为10kg、63.5kg和120kg，分别称为轻型、重型和超重型动力触探。轻型动力触探适用于粘性土和粉土，常用来检测浅基础地基承载力和基坑验槽。重型动力触探适用于砂土和砾卵石，超重型动力触探适用于砾卵石，标准贯入试验适用于粘性土、粉土和砂土。而动力触探装置就是基于上述理论制作的用于判定土壤力学性质的一种仪器。
但是，现有动力触探装置需要人工记录击锤的下落次数，若次数超过百次容易记录错误，且装置在锤击过程中，需要多人手扶，才能保证探头垂直打入土中；因此，不满足现有的需求，对此我们提出了一种用于地下管线探测的动力触探装置。
实用新型内容
本实用新型的目的在于提供一种用于地下管线探测的动力触探装置，以解决上述背景技术中提出的现有动力触探装置需要人工记录击锤的下落次数，若次数超过百次容易记录错误，且装置在锤击过程中，需要多人手扶，才能保证 探头垂直打入土中的问题。

优选的，所述支架座的内部设置有轴承，所述探杆的一端贯穿并延伸至轴承内部。
优选的，所述轴承的内部设置有滚珠，且滚珠设置有若干个。

与现有技术相比，本实用新型的有益效果是：
1、本实用新型通过在击锤杆内安装微型金属光电传感器，击锤在一次锤击过程中，会由上滑和下落经过两次微型金属光电传感器，所以在记录时，只需将金属光电传感器测量的数字除二即可得出击锤的下落次数，无需人工记录，提高了准确性。
2、通过设置伸缩支架，且伸缩支架设置有三个，三个伸缩支架能够有效提高动力触探装置的稳定性，保证探头能垂直进行土壤，无需人工手扶，节省人力，伸缩支架的一端安装有橡胶支脚，能够避免伸缩支架因冲击力过大损坏。

具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。
请参阅图1-3，本实用新型提供的一种实施例：一种用于地下管线探测的动力触探装置，包括手柄挡扣1，手柄挡扣1的下方安装有击锤杆2，击锤杆2的外壁上安装有击锤4，击锤4用于冲击探杆8，使探头9进入土壤，击锤4的两侧均安装有手柄5，手柄5能够更方便的上拉击锤4，手柄5的外壁上设置有防滑套6，防滑套6能够起到防止手柄5脱手的作用，击锤杆2的一端安装有落锤挡扣7，落锤挡扣7能够在击锤4下落时起到阻挡的作用，落锤挡扣7的下方安装有探杆8，探杆8上设置有刻度线15，刻度线15能够更方便的对探入深度进 行记录，探杆8的一端安装有探头9，探杆8的外壁上安装有支架座10，支架座10的外壁上安装有伸缩支架12，且伸缩支架12设置有三个，伸缩支架12能够提高动力触探装置的稳定性，伸缩支架12通过转轴11与支架座10转动连接，伸缩支架12的外壁上设置有伸缩锁扣13，伸缩锁扣13能够调节伸缩支架12的长度，以适应不同长度的探杆8。
进一步，击锤4的中间位置处设置有连接孔401，且击锤4通过连接孔401与击锤杆2滑动连接，通过手柄5上拉击锤4使其沿连接孔401自然滑落，冲击落锤挡扣7，能够将探头9打入土壤。
进一步，击锤杆2的内部安装有微型金属光电传感器3，且微型金属光电传感器3采用型号为PR-FB15N1的微型金属光电传感器3，微型金属光电传感器3能够记录击锤4的滑落次数。
进一步，支架座10的内部设置有轴承16，探杆8的一端贯穿并延伸至轴承16内部，轴承16起到了支撑支架座10的作用，且在支撑的同时不会影响探杆8的伸入。
进一步，轴承16的内部设置有滚珠17，且滚珠17设置有若干个，滚珠17能够使探杆8的移动更加稳定。
进一步，三个伸缩支架12的一端均安装有橡胶支脚14，橡胶支脚14能够在击锤4冲击时起到缓冲的作用，避免伸缩支架12因冲击力过大损坏。
工作原理：使用时，将动力触探装置放置在待测土壤上，展开伸缩支架12，并根据探杆8长度对支架进行调节，调节完毕后，通过手柄5上拉击锤4使其沿连接孔401自然滑落，冲击落锤挡扣7，将探头9打入土壤，探杆8每入土一定深度，需记录一次锤击次数，因击锤杆2内安装有微型金属光电传感器3，击 锤4每锤击一次会由上滑到下落经过两次微型金属光电传感器3，所以只需将传感器上记录的数字除二即可得出锤击次数，无需人工记录，提高准确性，待数据记录完毕后，可得出该地土壤是否为管线沟槽回填土，并判断出下方是否埋有低下管线。
对于本领域技术人员而言，显然本实用新型不限于上述示范性实施例的细节，而且在不背离本实用新型的精神或基本特征的情况下，能够以其他的具体形式实现本实用新型。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本实用新型的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本实用新型内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
