Quick-connection type water braid

Abstract

The invention discloses a quick-connection type water braid. The quick-connection type water braid comprises a water pipe connecting part and a drill rod connecting part which are connected with each other, the drill rod connecting part is provided with a quick-connection cavity, the end part of a drill rod extends into the quick-connection cavity, the quick-connection cavity is in sealing fit with the end part of the drill rod, a clamping device is arranged in the quick-connection cavity, and the clamping device is used for automatically clamping the outer circle of the drill rod so that the drill rod and the drill rod connecting part can be fixed. When the left end of the drill rod is mounted in the quick-connection cavity, the drill rod and the drill rod connecting part are automatically connected and fixed through the clamping device, the water braid and the drill rod are quickly connected, so that the problem that time and labor are wasted when a conventional threaded connection type water braid is screwed is solved, and the drilling efficiency during drilling can be greatly improved.

Description

Technical field [0001] The present invention relates to the field of mine mechanical technology, and more particularly to a fast-linking water. Background technique [0002] During the construction of the drilling, the water is connected to the water pipe or a duct, and the other end is connected to the drill pipe, which is a transition device connected between the drill rod and the line to enter the drill pipe in the external flushing liquid or high pressure air into the drill pipe. Inside. For example, the rinsing liquid is passed through the water in operation, providing cooling and slag for the drill portion of the hole. The existing water and drill rod connections are typically threaded. Each up and down a drill pipe needs to be removed once, loose or tighten the water, it needs to be auxiliary disassembly, and the loading and unloading time, the labor intensity is large It also severely reduces the efficiency of the drilling, and the water thread is reduced after repeated r...

AI Technical Summary

Problems solved by technology

The existing braids and drill pipes are usually connected by threads, and the braids need to be disassembled once for each drill pipe. When the braids are loosened or tightened, tools are required to assist the disassembly, and the loading and unloading time is long and the labor intensity is high. , also seriously reduces the drilling efficiency, and the sealing effect of the thread of the water braid is reduced after repeated disassembly, which is prone to water leakage and affects the life of the water braid
