Fluid-driven tunneling device

Abstract

The invention discloses a fluid-driven tunneling device, which uses fluid such as hydraulic oil, water or compressed air as energy to drive a rotating device to move. With a simple structure, large torque, high rotating speed, high transmission efficiency, low energy consumption and small vibration, the device can meet the requirements of the tunneling device on torque, rotating speed and runningstability well, at the same time, the fluid power device comprises an outer ring and a core body, wherein at least one-step or more-step secondary flushing channels are arranged between a nozzle and an exhaust port of the outer ring surface of the core body, the fluid enters from an inlet channel, is ejected step by step through the nozzle of the core body and the secondary flushing channels, actson at least two driving concave parts in the circumferential direction of the outer ring, generates thrust on the driving concave parts to push the outer ring to rotate and do work, and realizes power output; and finally, the fluid is discharged through the exhaust port of the core body from an exhaust channel.

Description

technical field [0001] The invention discloses a fluid-driven tunneling device, which belongs to the technical field of mining mechanical devices according to the International Patent Classification (IPC). Background technique [0002] Existing various tunneling devices, especially percussion drilling devices, are widely used in building construction and mine operations. It mostly adopts an engine and a rotating device, and the rotating device is driven by the engine to rotate to drive the working device at the front end of the rotating device to work. [0003] Since the operating device needs a large torque when it is working, and the working space is limited, the volume of the engine cannot be too large, and the existing engines are mostly pneumatic engines or hydraulic engines. [0004] For the pneumatic engine in the engine, the current research direction is to develop compact, efficient and reliable small engines, most of which are in the stage of trial and trial produ...

Problems solved by technology

At present, most gas engine design prototypes are based on piston engines or vane pumps, and the energy conversion is realized through the heat of the heat exchanger to achieve power output, but the structure is complex and the efficiency is low, and it is difficult to meet the requirements of endurance.

[0005] The hydraulic engine is mostly a low-speed hydraulic motor with low working efficiency, and the structure of the motor itself is complicated, the maintenance and use are cumbersome, and the working stability is poor.
