Hydraulic high-speed drill

Abstract

The invention discloses a hydraulic high-speed drill. The front end of the body of an excavator is hinged with the lower end of a drillrig seat through a movable arm; the drillrig seat is fixed in the middle part of the drillrig; a power head is arranged on the drillrig through a skateboard; the output shaft of the power head is connected with the upper end of a drill stem through a coupler; the lower end of the drill stem penetrates a movable locating frame and a fixed locating frame in sequence; the upper end of the drill stem is provided with a first fixed pulley; the lower end of the drillrig is provided with a second fixed pulley; the lower part of the drillrig is provided with a towing jack; two movable pulleys which are arranged up and down are arranged on a piston rod of the towing jack through a bracket; two chains and two steel ropes are arranged between the fixed pulleys and the movable pulleys; the power head and the drillrig can be pulled to move up and down through the fit between the chains and the pulleys, while the movable locating frame can be pulled to move up and down through the fit between the steel ropes and the pulleys. The hydraulic high-speed drill has the advantages of simple and compact structure, low cost, easy operation, convenient maintenance, flexible and reliable motion, low working intensity of the workers, high working efficiency and broad applicable range.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, in particular to a hydraulic high-speed drilling machine. Background technique [0002] At present, special drilling equipment is required for drilling blastholes on the construction site and geological exploration. The drilling of blastholes on the construction site is generally completed by jackhammers. The jackhammers are pneumatically driven and manually operated. The depth of the hole is shallow, the applicable surface is narrow, etc., and the labor intensity of the operator is very high. Geological prospecting operations usually use special drilling rigs, which are complex in structure, high in cost, difficult to maintain, and need to be connected with drill pipes when drilling deeper holes, which is not only cumbersome to operate, but also affects the efficiency of drilling. Contents of the invention [0003] The technical problem to be solved by the present invention is t...

[0002] At present, special drilling equipment is required for drilling blastholes on the construction site and geological exploration. The drilling of blastholes on the construction site is generally completed by jackhammers. The jackhammers are pneumatically driven and manually operated. The hole depth is shallow, the applicable surface is narrow, etc., and the labor intensity of the operator is very high

However, geological exploration usually uses special drilling rigs, which are complex in structure, high in cost, difficult to maintain, and need to be connected with drill pipes when drilling deep holes, which is not only cumbersome to operate, but also affects drilling efficiency.
