Description

电力电缆隧道弧形支架
技术领域
本实用新型涉及一种电缆用支架，尤其是一种电力电缆隧道弧形支架。
背景技术
国内已有的隧道电缆通常采用竖直的支架，由于隧道的截面通常呈圆弧形，这种支架并不适合隧道内使用，普遍存在占用空间较大的不足，而且焊接的直线支架还容易出现强度方面的问题。
发明内容
本实用新型针对上述问题，提出一种可充分利用圆形隧道的内空间，提高支架的可靠性和稳定性的电力电缆隧道弧形支架，采用弧形的结构，并配合可拆卸紧固件实现若干水平横担的连接，非常便于施工。
为了实现上述发明目的，本实用新型的电力电缆隧道弧形支架，包括：
弧形立柱，呈圆弧形结构，沿所述弧形立柱上开设了若干等弧长的安装孔；
若干水平横担，包括一水平部，在所述水平部的一端有与水平部之间呈一定夹角的连接部，在所述连接部和水平部上开设有连接孔；
可拆卸连接件，将所述安装孔和所述连接孔连为一体。
附图说明
下面，参照附图，对于熟悉本技术领域的人员而言，从对本实用新型的详细描述中，本实用新型的上述和其他目的、特征和优点将显而易见。
图1是本实用新型的结构示意图；
图2是图1中水平横担20的结构示意图。
具体实施方式
请参见附图1和2所示，本实用新型的电力电缆隧道弧形支架包括一个弧形的立柱10、和若干水平横担20组成，弧形立柱10呈圆弧形结构，沿弧形立柱10上的弧面上开设了若干等弧长的安装孔101。水平横担20的主体为一水平部201，在水平部201的一端有一连接部202，连接部202与水平部201之间有一定夹角，二者为一体化结构。在连接部202上开设有第一连接孔2021、在水平部201上近连接部202一端开设第二连接孔2011。
安装时，弧形立柱10紧贴隧道内的预制钢带(未图示出)，弧形立柱10与圆形隧道内的预制钢带采用焊接或螺栓连接，这种紧贴隧道的方式可以充分利用圆形隧道的内空间，提高支架的可靠性和稳定性。将水平横担20的水平部201和连接部202一端通过第一、二连接孔2021、2011与弧形立柱10用螺栓紧固连接，在布局上，水平横担20可以按照弧形立柱10的等弧长来设置，由此形成若干水平横担20相互平行的布局。
此外，水平横担20上可根据设计要求安装电缆约束线夹或固定线夹，横担20外侧加装塑料保护套，避免工人和电缆被划伤，防止由此引发的事故。弧形立柱10按规定的间距布满安装孔101，便于水平横担20安装位置的上下调节。所有金属构件均采用热浸镀锌工艺进行表面处理，提高支架的防腐蚀性能，提高支架的使用寿命。
以上诸实施例仅供说明本实用新型之用，而非对本实用新型的限制，有关技术领域的技术人员，在不脱离本实用新型的精神和范围的情况下，还可以作出各种变换或变化，因此所有等同的技术方案也应该属于本实用新型的范畴应由各权利要求限定。
