Track wheel lifting device and wheel type drilling machine

Abstract

The invention discloses a track wheel lifting device. The track wheel lifting device comprises a chassis frame, a crankshaft and connecting rod mechanism, track wheels and a driving mechanism. The crankshaft and connecting rod mechanism comprises crankshafts and driving connecting rods. The crankshafts are arranged on the chassis frame, and each driving connecting rod is arranged at one end of theaxis of the corresponding crankshaft. Each track wheel is arranged at the end, deviating from the corresponding driving connecting rod, of the corresponding crankshaft and is eccentric relative to the axis of the corresponding crankshaft. The driving mechanism is arranged on the chassis frame, is connected with the driving connecting rods in a driving mode and is used for driving the crankshaftsto rotate through the driving connecting rods and enabling the track wheels to swing up and down. The stable ascent and decent of the track wheels can be achieved through the track wheel lifting device, and therefore the switching of the track wheels and tires can be achieved, and a drilling machine can move in a tracked roadway through tracks and can also travel in a trackless roadway through thetires.

Description

technical field

[0001] The invention belongs to the technical field of mining machinery, and in particular relates to a rail wheel lifting device and a wheeled drilling machine. Background technique

[0002] A raise drilling rig is a mechanical equipment for wellbore excavation that breaks rocks to form holes and can be reversely reamed by rotary drilling.

[0003] Many small and medium-sized mines in China are not equipped with special ramps for mining equipment to go down the well. Most drilling rigs need to disassemble the equipment during transportation, and then transport the main engine part and the pump station part to the underground through special transportation equipment, and then Assembled, and many large parts of some drilling rigs cannot be transported underground due to the limitation of the transportation space of the transportation equipment. Even if some mines have special ramps, the existing domestic raise drilling rigs are all fixed models, that is, the ...
