Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a drilling device for bridge construction. Background Art

[0002] Bridges generally refer to structures built on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient. Bridges are generally composed of superstructures, substructures, supports, and auxiliary structures, and drilling devices are required in the longitudinal construction process of bridges.

[0003] Generally, the drilling machine used in the drilling process is mainly a drill bit, which is usually manually operated for drilling operations. A lot of vibrations will be generated when the drill bit is working, and the construction workers need to hold the drill bit tightly to ensure the integrity of the drill hole. Such operations will consume more manpower. After several drilling operations, the construction workers will become tired, and the drilling efficiency of the entire bridge construction will be greatly reduced. In addition, the locations of some drill holes are more biased, which will increase the difficulty of construction. The construction workers will be more tired during operation, and the drill bit may not be held, which may easily lead to safety problems. Utility Model Content
