由于船舶的设计以及现场施工实际需要，船舶甲板、舱室内开着大量的人孔、工艺孔，为了防止作业人员不慎踩空，发生高坠事件，目前普遍方法是在人孔、工艺孔处安装人孔护栏。普通的人孔护栏由夹具、立柱、与护栏组成，可以回收重复利用。
然而，船舶建造有搭载顺序，船体会陆陆续续地形成大大小小的舱室，部分人孔护栏会留在舱室里，但人孔护栏的规格是固定的，而且比人孔、工艺孔的尺寸要大，在船舶建造完后将无法从舱室里取出来，需要破坏性解体才能取出，导致取出后无法再次使用，造成大量浪费。
实用新型内容
本实用新型的目的在于提出一种夹口人孔护栏，其通用性强，且便于从舱室内取出，有利于重复使用，减少浪费，降低成本。

具体实施方式
下面结合附图并通过具体实施方式来进一步说明本实用新型的技术方 案。
如图1至9所示，本实用新型的一示例提供的一种夹口人孔护栏，包括圆环形的护栏，护栏包括至少两段圆弧形的护栏段，相邻两个护栏段之间可拆卸连接，其中一个护栏段的一侧连接有竖向设置的立柱1，立柱1垂直连接有夹具2，夹具2能够连接于夹口人孔的周围。其通过夹具能够夹持于夹口人孔的周围，利用立柱和护栏起到防护作用，有效防止人员踏空掉落，其护栏通过多个圆弧形的护栏段可拆卸连接而成，在使用完成后，将每个护栏段拆卸，从而可以变成小尺寸的零件，便于从舱室内取出，有利于重复使用，减少浪费，降低成本，且其不会受到人孔尺寸的限制，因而通用性较强。
优选的，在本实施例中，护栏包括两段半圆弧形的护栏段，一段护栏段为护栏A段3，另一段护栏段为护栏B段4，护栏A段3的一端通过连接件一7与护栏B段4的一端可拆卸连接，护栏B段4的另一端通过连接件二8与护栏B段4的另一端可拆卸连接。
其中，连接件一7为槽钢结构，槽钢结构的两个底板通过焊接连接护栏A段3的一端，槽钢结构的隔板开设有第一连接孔71，护栏B段4的一端开设有护栏连接孔41，紧固件穿过第一连接孔71、护栏连接孔41，以实现连接件一7与护栏B段4的连接。
其中，连接件二8为角钢结构，角钢结构的一侧板通过焊接连接护栏A段3的另一端，角钢结构的另一侧板开设有第二连接孔81，护栏B段4的另一段开设有护栏连接孔41，紧固件穿过第二连接孔81、护栏连接孔41，以实现连接件二8与护栏B段4的连接。
在上述结构的基础上，护栏A段3连接立柱1。为了使护栏与立柱1之 间的支撑稳定可靠，立柱1与护栏A段3之间连接有至少两个斜撑5，任两个斜撑5的倾斜方向不同，斜撑5相对于立柱1的倾斜角度为30°～75°。该倾斜角度可以为30°、35°、40°、45°、50°、55°、60°、65°、70°，在本实施例中，倾斜角度为45°。
具体地，夹具2包括开口朝向与护栏的开口朝向垂直设置的U槽21，立柱1连接于U槽21的一侧板的表面，U槽21的该侧板开设有连接孔211，其中，连接孔211为两个，且间隔设置。U槽21的该侧板的外侧对应于连接孔211处焊接连接有螺母23。使用时，夹口人孔的侧壁卡入U槽21中，螺钉穿过螺母23、连接孔211后能够抵压于夹口人孔的侧壁上。需要取出时，只需松掉螺栓即可拆开护栏。
优选的，立柱1与U槽21的侧板之间通过焊接垂直连接，且焊接的焊角6范围为7～9mm，如7mm、7.5mm、8mm、8.5mm、9mm，在本实施例中，焊角为8mm。
进一步地，U槽21的外周套设有开口方向与U槽21的开口方向一致的加强材22，加强材22与U槽21通过焊接连接。
另外，为了使得护栏更加显眼，护栏与立柱1的外表面均涂有黄黑相间面漆层。
相对于现有的人孔护栏，本实用新型的结构采用将护栏拆分成A、B两段，从而实现护栏的拆卸以改变其尺寸，方便人孔护栏从舱室内取出，避免了破坏性解体导致无法重复使用造成浪费的缺陷。该夹口人孔护栏，所有船型通用，在取出后，可以安装于其他人孔中，实现重复使用，减少浪费，降低成本。
该夹口人孔护栏，具有如下优势：
1、适用于各型船舶上的面积在0.5平方米以下的工艺孔，方便拆装，特别适合在内底、舱室中使用。
2、护栏有斜撑，稳定性好，安全可靠。
3、护栏可以重复利用，减少浪费、节约成本。
4、按普通5万吨原油轮来算，每艘船有12个边舱，平均每个边舱需使用4个人孔护栏，每艘船至少能节约48个人孔护栏的费用。
5、传统护栏在船舶建造完成后需要两名切割人员连续工作8天才能拆除完成，而新型护栏拆装方便，无需切割人员介入，有效节约人工成本。
6、以南沙厂区2016年建造船舶计算，全年大约能够节约材料成本384000元和人工成本96000元，共计480000元。
以上结合具体实施例描述了本实用新型的技术原理。这些描述只是为了解释本实用新型的原理，而不能以任何方式解释为对本实用新型保护范围的限制。基于此处的解释，本领域的技术人员不需要付出创造性的劳动即可联想到本实用新型的其它具体实施方式，这些方式都将落入本实用新型的保护范围之内。
