Description

一种新型螺纹地桩及其连接件 技术领域
本发明涉及地桩技术领域，特别涉及一种新型螺纹地桩及用于新型螺纹地桩的连接件。
 背景技术
光伏支架，又称为太阳能电池板支架，是指用于安装、支撑太阳能电池板的专用支架。光伏支架通过固定在地面、屋顶或其他结构上，使太阳能电池板保持一定的倾斜角度，以最大限度地接收太阳辐射。光伏支架的基础主要分两大类，其中一种是水泥基础，一种是螺纹地桩基础，螺纹地桩基础由于施工的便捷所以使用的比例更大。
螺纹地桩是一种带螺旋叶片的金属或非金属材质的管桩，主要由管体、螺旋片和连接法兰盘三部分组成，螺旋片和法兰盘焊接在管体上。使用时，由地桩机旋拧入地下，代替原有的混凝土基础，顶端连接负载（如光伏支架）。在实际使用过程中，通常需要多次打桩，这就要求各个法兰盘处于同一高度水平。由于地质结构不同，通常地桩机在将螺纹地桩打入地面下时，很难保证将各个法兰盘保持在同一高度水平，且无法确保法兰盘上孔的朝向一致，会导致地桩顶端的连接出现角度偏差，在后续连接光伏支架时，导致光伏支架的角度出现偏差，给操作带来麻烦，影响工作效率。
此外，螺纹地桩法兰盘是跟支架底座连接的部分，其设计的合理性可以使现场施工效率提高。现有的光伏支架的基础螺纹地桩法兰盘结构，在使用的过程中，法兰盘不能够对支架底座进行调节，由于法兰盘与支架底座之间的连接方式单一，通过螺栓连接使得现场施工效率降低的问题，为此，本案应运而生。
发明内容
本发明的目的在于提供一种新型螺纹地桩，以解决现有法兰螺旋地桩，在使用过程中，无法保证打桩后各个地桩顶部的高度一致，及地桩顶部连接负载时朝向一致的问题，提高现场施工效率。本发明的另一目的在于提供一种用于新型螺纹地桩的连接件，可以根据需要多方向调整光伏支架的安装角度，以解决现有法兰盘结构，在使用过程中，光伏支架角度无法调节及现场施工效率低下的问题。
为达成上述目的，本发明的解决方案为：一种新型螺纹地桩，包括地桩本体，所述地桩本体的底部具有螺旋片，所述地桩本体通过螺旋片插入地面，所述地桩本体的顶部设有外螺纹段，所述地桩本体的顶部与动力设备连接。
进一步，所述外螺纹段通过焊接的方式固定在所述地桩本体的顶部。
进一步，所述地桩本体设有一加强筋，所述加强筋贯穿所述地桩本体设置在外螺纹段的下方。
进一步，所述螺旋片环绕设置在地桩本体底部的外侧壁，所述螺旋片与地桩本体一体成型，或所述螺旋片焊接在地桩本体的底部。
本发明的另一解决方案为：一种用于新型螺纹地桩的连接件，包括与上述地桩本体连接的管套，转动块、夹持机构、第一螺栓和第一螺母，所述管套开设有固定孔，所述固定孔的两端分别设有所述转动块，所述转动块在与固定孔对应的位置同轴开设有安装孔，所述第一螺栓穿过安装孔和固定孔与第一螺母配合将转动块与管套连接，使两个所述转动块在管套的两侧绕第一螺栓转动，所述夹持机构与转动块连接并通过所述转动块转动设置在管套的上方，所述夹持机构用于连接光伏支架。
进一步，所述转动块上设有垫片，所述垫片开设有与安装孔对应的圆孔，所述第一螺栓通过圆孔和固定孔从管套一侧的转动块穿过与另一侧的转动块连接，通过与第一螺母配合将两个所述转动块分别固定在管套的两侧。
进一步，所述安装孔呈长条形，所述第一螺栓在长条形安装孔内相对所述转动块移动。
进一步，所述转动块为中空结构，所述夹持机构包括U型件、固定连接件、夹具、第二螺栓和第二螺母，所述U型件倒置插入转动块中，所述U型件的两端在与安装孔对应的位置设有枢接孔，所述第一螺栓穿过枢接孔和安装孔将所述U型件与转动块连接，使所述U型件倒扣设置在管套的上方；
所述固定连接件设置在U型件的U形处，所述固定连接件开设有贯穿孔，所述贯穿孔的两端均设有所述夹具，两个所述夹具在与贯穿孔对应的位置同轴开设紧固孔，所述第二螺栓穿过紧固孔和贯穿孔与第二螺母配合将两个所述夹具分别固定在U型件的两端，通过两个所述夹具夹持固定光伏支架。
进一步，所述固定连接件的上表面为弧面，弧面的弧度与U型件U形处的弧度相适配，所述固定连接件通过弧面于U型件的U形处滑动，使两个所述夹具通过固定连接件于U型件U形处的两端移动，用于调节设置光伏支架的安装角度。
进一步，所述固定连接件两端的下方向内倾斜设置形成斜面，所述贯穿孔连通固定连接件两端的斜面，所述夹具的底部向外倾斜延伸形成与斜面配合的凸缘，凸缘开设有所述紧固孔，所述凸缘与U型件相抵接，通过第二螺栓和第二螺母螺纹配合将两个所述夹具与所述固定连接件固定在U型件的U形处。
采用上述方案后，本发明的有益效果在于：
与常规法兰地桩相比，本发明的新型螺纹地桩的地桩本体的顶部设置外螺旋段，通过外螺纹段与动力设备螺旋连接，将动力设备与地桩本体的顶部之间锁定呈一个整体，利用动力设备带动地桩本体旋转通过螺旋片直接将地桩本体打入地基内，打入地基后，如果地桩本体所处的水平度有偏差，可以通过旋转外螺纹段，调整地桩本体的水平度，使得每次打桩保持同一高度。另外，当地桩本体顶部需要连接负载时，可以通过外螺纹段旋转调节连接件的朝向，避免连接件因朝向不同导致安装角度产生偏差，本发明的结构简单，操作方便，新手也能迅速上手，可以大大提高现场施工的效率。
本发明用于新型螺纹地桩的连接件，通过管套与地桩连接，两个转动块通过第一螺栓分别设置在管套的两侧，使得两个转动块可以在管套的两侧绕第一螺栓转动，夹持机构与转动块连接并设置在管套的上方，用于夹持光伏支架，由于转动块通过第一螺栓可以在管套的两侧转动，因此，夹持机构可以通过转动块转动设置在管套的上方，进行上下转动调节，从而实现光伏支架安装角度的可调节设置，进而提高现场施工效率。

具体实施方式
以下结合附图及具体实施例对本发明做详细的说明。
本发明提供一种新型螺纹地桩，如图1所示，包括地桩本体1，所述地桩本体1的底部具有螺旋片11，所述地桩本体1通过螺旋片11插入地面，所述地桩本体1的顶部设有外螺纹段12，所述地桩本体1的顶部与动力设备连接（图中为未示出），借助动力设备将地桩本体1打入地下，最后地桩本体1的顶部与光伏支架连接，用于安装光伏支架（图中未示出）。
所述外螺纹段12采用焊接的方式与所述地桩本体1的顶部固定连接，具体的，所述地桩本体1为一空心圆棒，所述外螺纹段12的底端插入地桩本体1的顶部，通过焊接的方式固定在地桩本体1的顶部，为了防止外螺纹段12在使用过程中，因负载过重而掉落进地桩本体1内，所述外螺纹段12的底部开设有通孔，所述地桩本体1与通孔对应的位置开设有贯穿孔，在本实施例中，所述地桩本体1还设有一加强筋13，所述加强筋13穿过贯穿孔和通孔贯穿设置在外螺纹段12的下方，从而增加外螺纹段12的承重能力，见图3。
所述地桩本体1可以在打孔后放入孔中使用，也可以通过自身底端为锥状或者柱状而旋转插入地面，在本实施例中，为使地桩本体1能快速插入地面，优选为地桩本体为锥状；所述螺旋片11为一片、不连续的两片或多片的螺旋片11，不连续的两片或多片的所述螺旋片11不在同一螺旋道上，所述螺旋片11环绕设置在地桩本体底部1的外侧壁，重点参阅图2。
为进一步加快地桩本体1插入地面，所述螺旋片11与地桩本体1可以采用一体成型，也可以通过焊接的方式固定在地桩本体1的底部。
所述的新型螺纹地桩的工作过程如下：
使用时，将动力设备与地桩本体1的顶部连接，使带有螺旋片11的圆棒通过锥形头旋转插入地面，反复此操作，即可实现多次打桩，若每个地桩本体1插入地面的高度不一时，可以通过地桩本体1顶部的外螺纹段12再次连接动力设备，旋转地桩本体1进而调整地桩本体1的打桩深度；使得打桩后的地下部分起到固定作用，地上部分用于固定立柱、光伏支架、旗杆等或者其他结构。
与常规法兰地桩相比，本发明在地桩本体的顶部设置外螺旋段，通过外螺纹段与动力设备螺旋连接，将动力设备与地桩本体的顶部之间锁定呈一个整体，利用动力设备带动地桩本体旋转通过螺旋片直接将地桩本体打入地基内，打入地基后，如果地桩本体所处的水平度有偏差，可以通过旋转外螺纹段，调整地桩本体的水平度，使得每次打桩保持水平。
另外，当地桩本体顶部需要连接负载时，可以通过外螺纹段旋转调节连接件的朝向，避免连接件因朝向不同导致安装角度产生偏差，本发明的新型螺纹地桩结构简单，操作方便，新手也能迅速上手，可以大大提高现场施工的效率。
本发明还提供一种用于新型螺纹地桩的连接件，用于连接螺纹地桩和光伏支架，如图4和6所示，所述连接件包括与上述地桩本体连接的管套3，转动块4、夹持机构8、第一螺栓6和第一螺母7，所述管套3套接在地桩本体1的顶部后，便相对地桩本体1固定，管套3开设有固定孔，所述固定孔的两端分别设有所述转动块4，所述转动块4在与固定孔对应的位置同轴开设有安装孔41，所述第一螺栓6穿过安装孔41和固定孔与第一螺母7配合将转动块4与管套3连接，使两个所述转动块4在管套3的两侧绕第一螺栓6转动，所述夹持机构8与转动块4连接并通过所述转动块4转动设置在管套3的上方，所述夹持机构8用于连接光伏支架（图中未示出）。
本实施例中，转动块4可以通过第一螺栓6在管套3的两侧转动，因此，夹持机构8可以通过转动块4转动设置在管套3的上方，进行上下转动调节，从而实现对光伏支架安装角度的可调节设置，与现有基础螺旋地桩法兰盘结构通过螺栓连接其安装角度不可调节相比，本案可以实现光伏支架安装角度的调整，且结构简单，操作方便，能大幅度提高现场施工效率，大大节约施工时间，使得施工人员的工作时间降低。
具体的，如图5所示，所述转动块4上设有垫片5，所述垫片5开设有与安装孔41对应的圆孔51，所述第一螺栓6通过圆孔51和固定孔从管套3一侧的转动块4穿过与另一侧的转动块4连接，通过与第一螺母7配合将两个所述转动块4分别固定在管套3的两侧。
现场施工受地质结构的影响，地桩打歪的现象时常发生，这就使地桩的高度、尺寸出现偏差直接导致连接件无法使用，考虑到实际操作的问题，在本实施例中，所述安装孔41优选为长条形，通过调整第一螺栓6在长条形安装孔内的位置，使所述第一螺栓6相对所述转动块4移动，即使地桩打歪也可以通过安装孔41来调节光伏支架的安装角度。
为避免连接件与光伏支架连接后，因负载过重而导致转动块4与垫片5出现滑移风险，进而造成安全隐患，本实施例将所述垫片5和转动块4相对的两个侧面设计为相互配合的波纹面，使垫片5与转动块4啮合，在防止二者相互滑动的同时还能增强连接件的承载能力，一举两得。另外，垫片5通过第一螺栓6于转动块4的安装孔41内移动实现夹持机构8在水平方向上的调节，用于弥补地桩打歪后的尺寸差，使得现场施工能够顺利进行。
具体的，本案不对转动块4和垫片5的形状进行限定，他们可以是矩形、圆形、三角形等任何形状，但考虑到实际操作的便捷，在本实施例中，所述转动块4的横截面为长方形，所述垫片5的横截面为正方形，且所述垫片5的高度与转动块4的高度相同，避免垫片5与转动块4在转动时干涉到其他零件。
如图4所示，所述转动块4为中空结构，所述夹持机构8包括U型件81、固定连接件82、夹具83、第二螺栓84和第二螺母85，所述U型件81倒置插入转动块4中，所述U型件81的两端在与安装孔41对应的位置设有枢接孔811，所述第一螺栓6穿过枢接孔811和安装孔41将所述U型件81与转动块4连接，使所述U型件81倒扣设置在管套3的上方，重点参阅图5；所述固定连接件82滑动设置在U型件81的内侧，所述固定连接件82开设有贯穿孔821，所述贯穿孔821的两端均设有所述夹具83，两个所述夹具83在与贯穿孔821对应的位置同轴开设紧固孔832，所述第二螺栓84穿过紧固孔832和贯穿孔821与第二螺母85配合将两个所述夹具83分别固定在U型件81的两端，通过两个所述夹具83夹持固定光伏支架。具体的，所述夹具83沿径向向上延伸并在顶部折弯形成一倒钩831，所述倒钩831用于卡接光伏支架。
为实现光伏支架安装角度的多方向调节，在本实施例中，所述固定连接件82设置在U型件81的U形处，所述固定连接件82的上表面为与U型件81的U形处相适配的弧面，所述固定连接件82通过该弧面可以在U型件81的U形处滑动，使两个所述夹具83通过固定连接件82沿U型件81的轴向在U形处的两端移动，进而实现光伏支架在竖直方向上的角度调节，因此，本发明的连接件可以同时实现光伏支架在水平方向及竖直方向上的角度调节，而现有技术的地桩连接件要实现光伏支架安装角度的多方向调节，只能通过在不同方向上增加连接件的方式，即通过多个连接件来实现光伏支架安装角度的多方向调节。
进一步，为了加强U型件81的承重能力，所述固定连接件82两端的下方向内倾斜设置形成斜面，所述贯穿孔821连通固定连接件82两端的斜面，所述夹具83的底部向外倾斜延伸形成与斜面配合的凸缘，凸缘开设有所述紧固孔832，所述凸缘与U型件81相抵接，通过第二螺栓84和第二螺母85螺纹配合将两个所述夹具83与所述固定连接件82固定在U型件81的U形处。
由于U型件81倒置与转动块4连接的，考虑到第一螺栓6与转动块4的配合关系并结合实际使用需求，延长各个零件的使用寿命，在本实施中，所述U型件81的长度与转动块4的长度相同，所述枢接孔811和所述安装孔41的形状相同，均为长条形，第一螺栓6通过长条形枢接孔811于转动块4内移动，避免U型件81对第一螺栓6相对转动块4的移动造成干涉，从而实现对光伏支架的角度调节，进而提高现场施工效率，大大节约了施工时间，使得施工人员的工作时间降低。
以上所述仅为本发明的较佳实施例，并非对本案设计的限制，凡依本案的设计关键所做的等同变化，均落入本案的保护范围。
