Mechanical telescopic water gun based on turbo-worm transmission

Abstract

The invention discloses a mechanical telescopic water gun based on turbo-worm transmission. The mechanical telescopic water gun comprises a worm, a guide rod, a worm gear protecting plate, a sliding plate, a worm gear, an ejector rob, a water gun, a right-angle joint, a water gun high-pressure rotary joint, an eccentric connecting pipe, a top end cover, a slag discharge pipe and a high-pressure water pipe. In the process of hydraulic mining, the worm can be rotated according to the extension angle of the required water gun, and when the water gun reaches the set extension angle, the rotation of the worm can be controlled to fix the extension angle of the water gun and to crush the rock. The extension angle of the water gun is freely adjusted, and is convenient to extend and retract; and the distance between a nozzle of the water gun and ore bed can be controlled according to the design, the problem that the energy of high-pressure water is sharply reduced due to the submerged jet is avoided, so that the purpose of improving the energy utilization rate of high-pressure water jet is achieved, and finally the mining efficiency is improved.

Description

technical field [0001] The invention relates to a telescopic water gun suitable for borehole hydraulic mining, in particular to a mechanical telescopic water gun based on turbine and worm transmission. Background technique [0002] Drilling hydraulic mining technology is to drill a hole in the target area first, then place a high-pressure water gun at the depth of the target mine layer in the drill hole, use the energy carried by the high-speed fluid ejected by high pressure to break the rock, and finally the broken rock and drilling fluid form a solid-liquid mixture , is pumped to the surface by the surface device, and then separates the ore slurry to extract minerals. Borehole hydraulic mining technology has the advantages of low mining cost, high production efficiency, and little impact on the surrounding environment. The high-pressure water nozzle of the traditional hydraulic mining drilling tool is fixed on the outer wall of the drilling tool, and the position of the n...

Problems solved by technology

"CN104005767A" discloses an electronically controlled telescopic drilling tool for drilling hydraulic mining, but the remote control technology of the drilling tool is not perfect, the working environment of the stepping motor, reducer, and controller is harsh, and the sealed environment is not easy to dissipate heat. The telescopic part works in the slurry environment, which requires high sealing and is easy to be damaged

"CN203961980U" discloses a telescopic water gun based on spring chuck control, but when the water gun works under the condition of drilling fluid, the clamping force is not enough, the water gun is not fixed reliably, and when the water gun is not extended to the maximum angle, The water gun cannot be retracted, so a new technical solution is urgently needed in the existing technology to solve this problem
