具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点,下面结合附图和实施例对本发明做进一步说明。需要说明的是,在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明,但是,本发明还可以采用不同于在此描述的其他方式来实施,因此,本发明并不限于下面公开说明书的具体实施例的限制。
实施例1,如图1、图2、图3所示,本实施例提供一种自垂直定位立杆器,包括杆头1以及设置在杆头1下方的抱杆2,抱杆2远离杆头1的一端设置有用于固定抱杆2的固定装置3,抱杆2与固定装置3之间转动固定连接,所述杆头2包括呈倒置“U”型设置的杆头本体11,杆头本体11的主要作用是起到一个支架的作用,将其设置呈倒置的“U”型主要是这样的设置会产生两个支脚,方便固定抱杆2,抱杆2与杆头1之间采用螺栓固定的方式,在杆头本体11的顶部设置有用于拉升电线杆的提拉索滑轮组12,在杆头本体11上还设置有用于控制抱杆2沿固定装置3转动的抱杆提拉滑轮组13,抱杆提拉滑轮组13为在杆头本体11上设置了一个横杆(图中未标注),在横杆上设置的抱杆提拉滑轮组13,在本实施例中,所指的滑轮组都是由两个配合设置的定滑轮组成,为了实现电线杆的自动垂直,在本实施例中,将提拉索滑轮组12与抱杆提拉滑轮组13垂直设置,具体的说,提拉索滑轮组12与抱杆2转动方向垂直设置,这样,抱杆提拉滑轮组13就沿抱杆2转动的方向设置,这样的设置,有利于在施 工时稳定电线杆,使其不易发生摆动,影响固定,本实施例所指的抱杆2包括左右对称设置固定在杆头本体11上的第一抱杆21和第二抱杆22,第一抱杆21和第二抱杆22分别连接在杆头本体11的支脚上,且第一抱杆21和第二抱杆22倾斜固定在杆头本体11上,这样的设置,使第一抱杆21与第二抱杆22的顶端的延伸线和末端的连线组成一个等腰三角形,这样的设置,能够确保电线杆的垂直,当然,考虑到后期的运输,第一抱杆21和第二抱杆22活动固定在杆头本体11上,具体的说,可以通过螺栓或卡扣实现第一抱杆21、第二抱杆22与杆头本体11之间的固定,当不需要使用时,可以合拢第一抱杆21和第二抱杆22,方便运输,在本实施例中,采用螺栓固定的方式。为了减少人力的使用,在抱杆2上还设置有用于与提拉索滑轮组12通过绳索连接的电动卷扬机23以及用于与抱杆提拉滑轮组13通过绳索连接的手动卷扬机24,考虑到电线杆在提拉时,可以使用自动提拉,故设置了电动卷扬机,考虑到整个立杆器要与电线杆配合转动,故在本实施例中,使用手动卷扬机24来人工控制,具体的说,电动卷扬机为小型直流电动卷扬机:为动力装置,拉力>2吨,起提升电线杆作用,电源为12V,可使用单独蓄电池,亦可使用汽车电源;手动卷扬机为手摇绞盘式卷扬机。
通过上述的设置,利用提拉索滑轮组12与抱杆提拉滑轮组13来控制电线杆在竖立时的稳定,利用抱杆2的等腰设置以及与固定装置的转动设置,来实现电线杆的自动竖直,进而达到本发明的目的。
为了使本立杆器能够使用更多的场地,且能够保证立杆器的稳定性,故在本实施例中,固定装置3包括与抱杆2转动固定连接旋转地锚31以及套装在旋转地锚31外的均压板32,旋转地锚31与抱杆2之间通过转轴33固定连接,利用旋转地锚31来固定整个立杆器,然后在此基础上加设均压板32,然后通过加固钉34将均匀板32固定,进而起到更好的固定作用,且使本立杆器的使用范围更大。
为了使本实施例所提供的自垂直定位立杆器的适用范围更广,如8米杆、10米杆、12米杆(此三类杆为现有电网建设中,最常用的锥形电线杆)的应用, 在本实施例中,第一抱杆21和第二抱杆22为可伸缩铝杆,具体的说,第一抱杆1和第二抱杆均22有两个套装在一起的铝杆组成,在其连接处设置了伸缩节、锁紧母和限位栓,以便适应不同高度的电线杆。
为了使抱杆在应用时能够准确的设置出其应该的程度,故在抱杆上设置有定位孔26,每个定位孔26分别对应8米杆、10米杆和12米杆,同样,为了方便整个立杆器的固定,在抱杆2上还设置有定位索25,定位索25设置在第一抱杆21和第二抱杆22之间,具体的,定位索25应与第一抱杆21和第二抱杆22末端的连线水平,定位索25设置在靠近杆头本体11的位置处,同样,为了方便第一抱杆21和第二抱杆22的合拢,定位索25可拆卸设置在第一抱杆和第二抱杆之间。
为了更佳准确的确定电线杆达到垂直状态,为在本实施例中,在杆头本体11上设置有用于电线杆定位的定位铝板14,定位铝板14倾斜设置在杆头本体11上,具体的定位铝板14呈倒置的“U”型设置在杆头本体11上,将定位铝板14设置呈倒置的“U”型主要考虑到电线杆的顶部的形状,这样,当施工时,电线杆碰到定位铝板14即可确定电线杆处于垂直状态,由于,立杆器在施工时处于倾斜状态,故定位铝板14要倾斜设置在杆头本体11上。
考虑到无论是电动卷扬机23和手动卷扬机24都需使用绳索,为了防止绳索乱跑,故在本实施例中,在杆头本体11还设置有用于绳索导向的导索管15,在抱杆2上也设置了相应的导索管。
具体在施工时,由于电线杆地上部分、两个旋转地锚连线中心至杆坑中心、杆头限位铝板至两旋转地锚连线中心连线距离组成一个三角形,只要三个长度选取好符合勾股定理,立直后即为直角三角形,即电线杆垂直于地面(横向由于两抱杆为等腰三角形,一定垂直与地面),根据数学计算和经验值,立杆器满足如下数据:
1、杆头定位铝板至定位索中心:1.8米
2、立杆器可伸缩,定位孔对应8、10、12米规格锥形电线杆,定位索到两个旋转地锚连线中心长度分别为5米、6米、7米,电线杆埋深分别为1.2、1.7、 2米,地面至电线杆固定抱箍长度分别为4.6、5、5.3米。
下面就以8米杆为例,详细描述立杆过程:
如图4、图5、图6所示,收线,根据所要竖直的电线杆的长度,挖取相应深度的杆坑4以及马道5,在此处,需要的杆坑4的深度为1.2米,此也是国家标准的要求。
然后,将电线杆6根部放入杆坑4,电线杆6下部放入马道5中,并保持与马道5平直,虽然马道5有一定的倾斜角度,但由于电线杆6的地上部分较多,其还是处于水平状态。
将电线杆6放置好后,调整第一抱杆和第二抱杆的长度至定位孔的8米孔处,使整个立杆器的长度能够与电线杆6相配合,然后将立杆器平放,确保定位索25的中心位置与杆坑4的中心处于同一垂线上,抱杆2方向朝电线杆6头部放置。
然后,标记好抱杆2底部的位置,开始设置固定装置3,具体的说,用地锚机旋入地锚,将均压板套入地锚杆,打入加固钉,并通过转轴固定抱杆2,在固定时,尽量使抱杆2与旋转地锚之间的转动皱一些,这样,好控制,也安全。
在电线杆6上量出相应距离安装起吊固定抱箍,以8米杆为例,这个位置应处于整个电线杆6的5.8米的位置处,在此位置处挂接起吊索7,起吊索7通过提拉索滑轮组与电动卷扬机连接,在电线杆6杆顶安装抱杆提拉抱箍并挂接提拉索8,提拉索8通过抱杆提拉滑轮组与手动卷扬机连接。
待一切安装接受后,就可以进行起吊了,此时,先利用手动卷扬机提拉抱杆2,使整个立杆器和电线杆6接近垂直,然后,开启自动卷扬机,起吊电线杆6,随电线杆6升起,抱杆2也随电线杆6前倾,此时调整手动卷扬机,保持抱杆2于电线杆起吊索7最小角度至电线杆6接触定位铝板,电机自动停止,此时,由于事先设置好的位置,故此时的电线杆6一定处于垂直状态,紧固好手动卷扬机,然后,就可以向杆坑4内填土,并将其夯实;待杆坑4内的土夯实后,登杆摘取提拉索7和抱箍;最后,拆除抱杆2,工作结束。
以上所述,仅是本发明的较佳实施例而已,并非是对本发明作其它形式的限制,任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例应用于其它领域,但是凡是未脱离本发明技术方案内容,依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与改型,仍属于本发明技术方案的保护范围。
