Description
技术领域 technical field
本实用新型涉及一种敷设电力电缆用的金具，更具体的说，本实用新型涉一种可同时约束三根电缆的电力电缆金具。The utility model relates to a fitting for laying power cables, more specifically, the utility model relates to a fitting for power cables that can constrain three cables at the same time.
背景技术 Background technique
电力电缆隧道是城市化进程和电网建设必不可少的设施。以往，电力电缆隧道通常为矩形，为在此中敷设电力电缆，通常采用直线形角钢立柱和角钢横担，在单付横担上架设电力电缆。为了适用于吊具安装，此时所使用的电力电缆金具通常为矩形整体形状，或者，在所述金具上一体形成有尺寸、强度较大的用于安装、紧固螺栓及吊装用的构件。由此，导致电力电缆金具体积较大，占地面积也较大。Power cable tunnels are essential facilities for urbanization and power grid construction. In the past, power cable tunnels were usually rectangular. In order to lay power cables in them, straight angle steel columns and angle steel cross arms were usually used to erect power cables on single cross arms. In order to be suitable for the installation of the hanger, the power cable fittings used at this time are generally in the shape of a rectangle, or the fittings are integrally formed with components for installation, fastening bolts and hoisting with larger size and strength. As a result, the metal body of the power cable is larger in size and occupies a larger area.
随着城市化进程和电网建设的节奏加快，电力隧道的使用日益广泛。因此，对电力电缆的敷设也提出了更高的要求。With the accelerated pace of urbanization and power grid construction, power tunnels are increasingly used. Therefore, higher requirements are put forward for the laying of power cables.
例如，随着电力电缆的容积安装量的提高要求，需安装于电力隧道中的电力电缆数目也在日益增加。为应付该增加的电力电缆，所述电力电缆必须克服以往直线形安装的模式，视需要，在电力电缆隧道中将所述电力电缆弯曲安装。而以往的直线形的电力电缆金具安装无法满足此要求。For example, with the increase in the installation capacity of power cables, the number of power cables to be installed in the power tunnel is also increasing. In order to cope with the increased power cables, the power cables must be installed in a curved manner in the power cable tunnel if necessary, overcoming the conventional linear installation mode. However, the previous linear power cable fittings installation cannot meet this requirement.
另外，现代化的电力电缆隧道广泛采用圆形隧道，取代以往的安装电力电缆的直线形角钢立柱和角钢横担，电力电缆隧道中安装电力电缆金具的支架也采用了弧形支架。此时，继续使用以往的大体积矩形金具无法满足要求，且降低电力电缆隧道的空间使用效率。In addition, modern power cable tunnels widely use circular tunnels to replace the previous linear angle steel columns and angle steel cross arms for installing power cables. The brackets for installing power cable fittings in power cable tunnels also use arc brackets. At this time, continuing to use the conventional large-volume rectangular fittings cannot meet the requirements and reduce the space efficiency of the power cable tunnel.
