Problems solved by technology

However, in a special working environment, large construction machinery cannot give full play to its unique functions, and instead brings inconvenience to construction
[0003] For example, for the lead hole operation of the existing high-speed railway station, due to the narrow construction site, many restrictive conditions, and the special environment that is not conducive to the entry and construction of large machinery, the existing large lead hole machinery and ordinary down-the-hole drilling rigs are no longer suitable for this kind of construction. environment, unable to meet the construction requirements

Abstract

The invention discloses a drilling trolley suitable for existing line operation. The drilling trolley comprises a rail plate type walking system, and a horizontal hydraulic rotating system, a perpendicular hydraulic rotating system, a down-the-hole drill body support and a down-the-hole drill traction motor which are arranged on the rail plate type walking system. By means of the drilling trolley,the special requirements for existing high-speed rail service line hole guiding operation, operation height, construction safety and the like can be met, and the large machine transferring free timecan be shortened, and work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of a drilling trolley for reinforcing the foundation of rotary jetting piles on a high-speed railway business line, and in particular relates to a drilling trolley suitable for existing line operations. Background technique [0002] In the field of construction in our country, with the continuous maturity of construction technology, construction machinery has also been greatly improved with the maturity of technology. However, in a certain special working environment, large-scale construction machinery cannot give full play to its unique functions, and instead brings inconvenience to construction. [0003] For example, for the lead hole operation of the existing high-speed railway station, due to the narrow construction site, many restrictive conditions, and the special environment that is not conducive to the entry and construction of large machinery, the existing large lead hole machinery and ordinary down...
