The invention discloses a labor-saving cable device The cable device comprises a base and a water storage tank arranged on the top of the base A cavity is formed in the bottom, located right below the water storage tank of the base, and the top of the cavity is fixedly provided with a water supply pipe extending up and down; the extension section at the bottom of the water supply pipe stretchesinto the cavity, guide grooves are symmetrically formed in the left and right sides of the lower side of the cavity, a sliding plate extending left and right is arranged in the cavity which is betweenthe left guide groove and the right guide groove, the extension ends of left and right sides of the sliding plate respectively stretch into the guide grooves of left and right sides, and the left andright guide grooves are internally provided with first screw rods connected with threads of the sliding plate in a matched mode and arranged extending up and down; and the top ends of the first screwrods are connected with a first electric rotating machine in a matched mode, and the sliding plate in the cavity is rotatably connected to a hole-boring transfer rod extending up and down The labor-saving cable device is simple in structure and convenient to operate, working efficiency and flushing efficiency are improved, and labor is reduced

Labor-saving cable device

The invention discloses a mine dismountable hydraulic slag discharging drill rod, and belongs to the field of a mine drill rod. The mine dismountable hydraulic slag discharging drill rod comprises a hollow body of the drill rod, a sleeve and a water passing pipeline, wherein the sleeve sleeves the outside of the hollow body; the water passing pipeline is formed in the sleeve; the hollow part in the hollow body is a hollow passage of the drill rod; a slag crushing device is arranged in the hollow passage; the position of the hollow body and the located slag crushing device of the sleeve is divided into an upper section and a lower section capable of being opened and closed; the slag crushing device comprises a fixing ring, a rotating motor and an impeller; the slag crushing device is clamped and arranged in the hollow passage through the fixing ring; a plurality of impellers are arranged in the fixing ring; the impellers are driven by the rotating motor arranged in the center of the impellers. The mine dismountable hydraulic slag discharging drill rod solves the problems of easy drill clamping, low drilling speed and poor slag discharging effect of the existing mine drill rod. By using the novel technology, the technical problems in the mine drill rod hole forming are solved; the cost is greatly reduced; parts of easy-to-damage parts can be easily replaced; the operation efficiency is improved.

The invention discloses a high-pressure water jetting tunneling construction method. A high-pressure pump pipe is mounted on a high-pressure pump body. A spray gun is connected to the high-pressure pump pipe. The high-pressure pump pipe is sleeved into a pulley device and then sleeved into a water return pipe. The inner diameter of the pulley device is greater than or equal to the outer diameter of a high-pressure pump spray pipe. The inner diameter of the pulley device is not more than the outer diameter of the high-pressure pump spray pipe by 2 mm. The outer diameter of the pulley device isless than or equal to that of the water return pipe. The outer diameter of the pulley device is not less than the water return pipe by 1 mm. Under the action of power machinery, a high-pressure pump pumps and transports water into the high-pressure pump pipe. Under the action of impact force of the spray gun, tunneled soil is softened into mud. The water return pipe is pulled by the high-pressurepump pipe to do motion. Meanwhile, a striking ring is mounted at an external port of the water return pipe and continuously conducts tunneling to a deep place under the action of external machinery. The high-pressure water jetting tunneling construction method has the advantages that construction is easy and convenient, the application range is wide, and there is no need to destroy a road and objects on the ground, intercept a river and cut off transport.

The utility model discloses a drilling machine which can effectively improve the pore-forming rate, the drilling depth and the long-distance pore-forming efficiency. Drilling and crushing integrated and internal discharging way is adopted by the drilling machine firstly; the main body of the drilling machine is a drill stem; a crushing drill bit and a core taking drill bit are contained in the drill stem; a water filling pipe is arranged in the drill stem; the crushing drill bit is arranged in the core taking drill bit to realize drilling and crushing integration; a water inlet is formed in the tail part of the drill bit; the front end of the water filling pipe extends to the crushing drill bit to flush crushed drill slag; the drill stem is a novel drill rod which is hollow and is large in inner diameter; the water filling pipe is formed in the side wall to deliver high-pressure water; during cutting and drilling, a drilling machine revolving device drives the drill stem and the drill bit to revolve, and meanwhile, the high-pressure water is delivered through the water filling pipe; the end part of the drill bit firstly contacts a rock layer to drill a small section of rock core; with the propelling of the drill bit, the crushing drill bit in the drill bit contacts the rock core to crush the rock core, and the process is a drilling and crushing integrating process; the high-pressure water is used to discharge the drill slag out of the inner cavity of the drill stem. Therefore, the pore-forming rate is improved, the drilling depth is increased, and the long-distance pore-forming efficiency is improved.
