Coal-mine rubber-wheel all-hydraulic drilling machine

Abstract

The invention discloses a coal-mine rubber-wheel all-hydraulic drilling machine. The coal-mine rubber-wheel all-hydraulic drilling machine comprises a rubber-wheel walking chassis. The rubber-wheel walking chassis comprises a frame; a walking unit and multiple pairs of walking rubber wheels are arranged below the frame, and a diesel engine power cabin and a walking driving cabin are arranged on the front side of the rubber-wheel walking chassis, and are arranged at the front portion side by side and parallel to the walking direction; devices on the middle side of the rubber-wheel walking chassis are arranged in three rows as a whole, the middle row is provided with a motor power cabin, the left row is provided with an electromagnetic starter, the right row is provided with a wind-cooling radiator, and a drilling-machine working device is arranged on the back side of the rubber-wheel walking chassis. In this way, the self-driving characteristic and the flexible movement characteristic of the drilling machine are guaranteed, and the space requirements of a vehicle body under the special working conditions such as a coal mine roadway and tunnel excavation are met; meanwhile, the construction function of drilling is achieved, and the requirements of multi-azimuth multi-angle drilling construction underground are met.

Description

technical field [0001] The invention relates to the technical field of drilling machinery and auxiliary transportation, in particular to a rubber-wheeled full-hydraulic drilling rig mainly used for underground drilling in coal mines. Background technique [0002] At present, the drilling rigs used in coal mines at home and abroad are mainly crawler and crawler drilling rigs. When going up and down the mine and reverse, the power supply car or cable is basically used to provide the power source for the drilling rig; and for inclined shaft coal mines and transportation Coal mines with better conditions, especially mines transported by trackless rubber wheels such as Shendong Shanxi, use other auxiliary vehicles to transport the drilling rig to the transfer point, and then rely on its own crawler to walk, causing the drilling rig to travel from the mine to the working face or the working face. It is very inefficient when transitioning between sites, which not only seriously aff...

[0002] At present, the drilling rigs used in coal mines at home and abroad are mainly crawler and crawler drilling rigs. When going up and down the mine and reverse, the power supply car or cable is basically used to provide the power source for the drilling rig; and for inclined shaft coal mines and transportation Coal mines with better conditions, especially mines transported by trackless rubber wheels such as Shendong Shanxi, use other auxiliary vehicles to transport the drilling rig to the transfer point, and then rely on its own crawler to walk, causing the drilling rig to travel from the mine to the working face or the working face. It is very inefficient when transitioning between sites, which not only seriously affects the efficient utilization of drilling rigs, but also is labor-intensive for relocation, and the coordination of various processes is time-consuming and laborious

The distance between the transfer point and the working surface of the drilling rig needs to rely on its own crawler. At the end of a walking round, it must rely on several workers to drag the cable forward and supply power to the drilling rig from the next electric cabinet, so that the drilling rig can proceed. A round of walking, such a cycle, until reaching the working surface, in the whole process, the walking speed is slow, the comprehensive average speed is lower than 2km / h, not only the labor intensity of the workers is high, affecting other processes, but also the crawler walking will have a certain impact on the road surface destroy
