Abstract

A trolley line support for crane power supply lines is provided. The trolley line support comprises an angle steel column (3), an upper angle steel beam (7), a middle angle steel beam (8), and a lower angle steel beam (9). The trolley line support is characterized by the angle steel column (3) with a side length of 8 to 10 cm and a length of 785 mm, and the middle angle steel beam (8) with a side length of 8 to 10 cm and a length of 355 mm. One end of the middle angle steel beam (8) is tack-welded on the middle of the angle steel column (3), and the other end is provided with connection holes. The upper angle steel beam (7) and the lower angle steel beam (9) are angle steels with side lengths of 8 to 10 cm and lengths of 630 mm, and the middle parts of the two angle steel beams are tack-welded on the upper and the lower ends of the angle steel column (3) respectively. Connection holes are arranged on one end of the upper angle steel beam (7) and one end of the lower angle steel beam (9), wherein the ends are on the same side with the middle angle steel beam (8). The trolley line support and a manufacturing method of the trolley line support are advantageous in that the stability and safety of trolley line supports are improved, and costs of materials and labor are reduced.

Description

technical field [0001] The invention relates to a support, in particular to a trolley line support for a crane power supply line and a manufacturing method thereof. Background technique [0002] The trolley line is a "special wire" that provides power to mobile equipment (mainly cranes, cranes, cranes). 06D401-1 "Installation of Crane Power Supply Lines" National Building Standard Atlas specifies in detail the methods of installation of crane bare conductors, crane moving cables and crane safety conductors in general environments. This atlas makes specific regulations on the installation of trolley line brackets in the installation of crane power supply lines: the accessory brackets of trolley lines should be installed vertically with the driving rail, and all brackets should be kept level with the driving rail. The installation distance is 2m per set. In order to ensure the overall straight line of the sliding contact line, it is required that the vertical error of the br...
