The first stroke top plate (21-7) is connected, the upper end of the first stroke top plate (21-7) is provided with a first motor base (21-8), and the upper end of the first motor base (21-8) is provided with a drilling motor ( 21‑9).

Description

technical field [0001] The invention belongs to the technical field of subway construction, in particular to a drilling arm. Background technique [0002] In the construction of the subway section, the installation and construction process of the cable support and hanger is often involved. At present, the installation of the support and hanger is carried out by manual drilling. There is no special intelligent equipment suitable for the positioning and drilling of the subway tunnel wall. Because the tunnel wall is curved, There are great difficulties in the construction measurement stage. Due to the high installation height, it is time-consuming and labor-intensive to drill holes for the support and hanger. In view of this situation, based on the characteristics of long section distance, high work repeatability, fixed distance between supports and hangers and consistent installation height, and fixed distance between both sides of the tunnel and the center of the rail, etc., ...
