Description

Portable swing arm device

Technical Field

The utility model relates to a technical field is consolidated to the crossbeam, concretely relates to portable swing arm device.

Background

The bridge foundation is a foundation for use on a bridge, belongs to the lower structure of the whole bridge, is directly contacted with the ground, bears the weight of the bridge, and has enough strength and stability in order to ensure the normal use and safety of the bridge, and the deformation should be within an allowable range, compared with the common building foundation, the bridge foundation is deeply buried. When beating bridge foundation, use the drill bit of a lesson to beat the foundation, because the drill bit is very heavy, at the concatenation in-process, need use the chain instrument to drive the drill bit and move the position that corresponds and splice, traditional mode is fixed the chain instrument in a place, but can't remove the chain instrument like this for the space of operation is too little, and it is more troublesome to remove the drill bit.
