Drilling device for segmental beam

Abstract

The invention relates to the technical field of drilling mechanical equipment, and particularly discloses a drilling device for a segmental beam. The drilling device comprises a mounting frame and a guide rail located on the side face of the mounting frame. The guide rail is provided with a horizontally movable slide block, the slide block is provided with a mounting base for installing a drivingmechanism, the output end of the driving mechanism is provided with a detachable drill bit for drilling, and the outside of the guide rail is uniformly provided with a plurality of first positioning screw holes. According to the drilling device, the movement of the mounting base and the driving mechanism is realized by moving the slide block horizontally on the guide rail, whether the detachable drill bit is always in the horizontal position in the drilling process through the cooperation of the slide block and the guide rail, the stability of drilling operation is effectively ensured, balancecan be maintained without manually hand support, and the problem that an existing drilling device for the segmental beam needs manually hand support to maintain the balance and thus physical consumption of an operator is increased is solved.

Description

technical field [0001] The invention relates to the technical field of punching mechanical equipment, in particular to a punching device for segmental beams. Background technique [0002] With the continuous development of science and technology and the advancement of prefabricated segmental assembly construction technology, there is room for further improvement in the construction method of segmental assembly beams. Among them, segmental assembled beam (segmental beam) is a commonly used construction technology in building construction. Its principle is to divide the bridge superstructure into several standard segments and prefabricate multiple segmental beams. After the design requirements are met, the beam sections are transported from the beam storage yard to the beam erection place according to the assembly order by the beam transport vehicle and hoisted into place, and then assembled and erected. [0003] At present, when segmental beams are assembled and erected, it ...
