Problems solved by technology

[0002] At present, due to the large number of drilling arrangements and the large amount of construction work used for tunnel drilling, the comprehensive drilling efficiency of the drilling rig, such as drilling, movement, and stabilization, requires high drilling efficiency and heavy weight.
However, the existing drilling rigs on the market usually have a large overall size, a small adjustable azimuth angle of the drill boom, and have disadvantages such as bulky moving machine, large overall size, and low comprehensive drilling efficiency, which cannot better meet the requirements of tunnel drilling construction.

Abstract

The invention relates to a track type lifting platform hydraulic drilling rig and a working method thereof, and belongs to the technical field of drilling rig equipment. The drilling rig comprises a power system, a hydraulic system, a travelling supporting system, a drilling-in system and an electrical system, and the power system provides power output for the whole drilling rig; the travelling supporting system comprises a base, the lower portion of the base is provided with a track, four supporting vertical columns are arranged around the base, and traveling and supporting are provided; theupper portion of the base is provided with a lifting platform, the upper portion of the lifting platform is provided with the drilling-in system, and the drilling-in system is used for providing drilling-in operation; the lifting platform is further provided with the hydraulic system which transmits hydraulic power for all oil cylinder assemblies; and the upper portion of the lifting platform is provided with a first supporting oil cylinder, and a second supporting oil cylinder is arranged between the lifting platform and the base. The track type lifting platform hydraulic drilling rig is small in whole machine size, the adjustable range of drilling hole azimuthal angles is large, the track type lifting platform hydraulic drilling rig adapts to the uneven ground and ground with the slope through a track traveling mechanism and a supporting mechanism, and tunnel hole drilling construction requirements can be well met.

Description

technical field [0001] The invention relates to a crawler-type lifting platform hydraulic drilling rig and a working method thereof, belonging to the technical field of drilling rig equipment. Background technique [0002] At present, due to the large number of drilling arrangements and the large amount of construction work used for tunnel drilling, the comprehensive drilling efficiency of drilling, movement, and stabilization of the drilling rig is required to be high and heavy. However, the existing drilling rigs on the market usually have a large overall size, a small adjustable azimuth angle of the drill boom, and have disadvantages such as bulky moving machine, large overall size, and low comprehensive drilling efficiency, which cannot better meet the requirements of tunnel drilling construction. Therefore, there is an urgent need for a drilling rig with a smaller overall size, a short time for moving and stabilizing assistance, and convenient azimuth adjustment. Cont...
