Abstract

The invention discloses a sea-route driller, and comprises a driller framework, a driller and a sleeve arranged on the framework. The bottom of the framework (21) is equipped with a walking device and a parking device. A drill-blasting vessel is equipped with a rail (17) corresponding to the walking device. The framework (21) is equipped with a sleeve-clamping device (12) corresponding to the sleeve (16), and is also equipped with a sleeve clamping device compensation oil cylinder (13) corresponding to the sleeve-clamping device. The invention is the sea-route driller, which uses a hydraulic motor to drive a rail wheel to make the driller walk by itself, make a hydraulic oil cylinder raise the driller framework, make a drilling rod be connected or dismantled automatically, make the sleevebe dismantled, make the driller park automatically, make the combining driller framework be capable of adjusting the lifting height of a hydraulic crane. The driller is simple in operation and reliable in performance, effectively reduces the auxiliary operating time for drilling by a sea-route driller, reduces the labor intensity of operators and promotes the working efficiency and construction safety.

Description

technical field [0001] The invention relates to a drilling rig, in particular to a channel drilling rig. Background technique [0002] Channel drilling rigs are widely used in drilling blast holes in underwater engineering reefs such as river channels, coastal waterways and port wharf construction. During the construction process of the channel drilling rig, it is necessary to locate the drilling hole and move the drilling rig. In order to meet the requirements of the drilling depth, it is often necessary to repeatedly connect and unload the drill pipe and casing, and park the car. These processes are very complicated. In the past, some machines were fixed on the drilling and blasting ship and could not be moved. It was necessary to move the ship to locate the drilling holes. In this way, all the drilling rigs on the ship had to drill the holes before moving the ship. When one drilling rig stopped for some reason, other drilling rigs could not. In addition, human-shaped shi...

During the construction process of the channel drilling rig, it is necessary to locate the drilling and move the drilling rig. In order to meet the requirements of the drilling depth, it is often necessary to repeatedly connect and unload the drill pipe and casing, and park the car. These processes are very complicated.

In the past, some machines were fixed on the drilling and blasting ship and could not be moved. It was necessary to move the ship to locate the drilling holes. In this way, all the drilling rigs on the ship had to drill the holes before moving the ship. When one drilling rig stopped for some reason, other drilling rigs could not. In addition, human-shaped ships are troublesome to move and accurate positioning is difficult. Some drilling rigs even use manpower to connect and unload drill pipes, hammer to lower casings and manually park, which greatly reduces the working efficiency of drilling rigs and the safety of construction.
