Full-automatic pipe storage box for hydraulic drill rig and control method thereof

Abstract

The invention discloses a full-automatic pipe storage box for a hydraulic drill rig and a control method thereof; the full-automatic pipe storage box comprises a box body with a plurality of tiers of inclined rail inside, an upper entry of the box body is provided with a pipe release unit, an upper pin and a release spring are connected between the box body and the pipe release unit, and the pipe release unit is tensioned by the release spring when in natural state; an exit of the box body is provided with a pipe discharge switch which may rotates around the lower pin, the pipe discharge switch comprises upper and lower retainers capable of blocking a drill pipe from rolling down, and the lower retainer and the box body are connected with a discharge spring; a discharge groove is arranged at the exit of the box body, the upper portion of a manipulator hydraulic cylinder is provided with a manipulator, the manipulator includes upper and lower jaws, the lower jaw is provided with a raised tentacle, the tentacle presses the discharge switch when the manipulator lowers to the discharge groove, and one drill pipe is released. The full-automatic pipe storage box is simple in structure and easy to move, numerous drill pipes may be stored in the box body, the control process is simple, and the full-automatic pipe storage box is highly adaptable to complex conditions.

Description

technical field [0001] The invention relates to the field of coal mine equipment, in particular to a fully automatic rod storage box for a hydraulic drilling machine and a control method. Background technique [0002] As coal mining moves towards deeper and harsher coal seams, the requirements for the safety and reliability of gas emissions are also increasing. As an important equipment for gas discharge, coal and coal rock drilling - hydraulic drilling rig, its performance requirements have also been further improved. [0003] Traditional drilling rigs mostly use manual methods to add and remove drill pipes. This method usually requires 2 to 3 people to work at the same time, which is labor-intensive, time-consuming and low in safety. [0004] The hydraulic drilling rig with automatic rod extension function is a new type of drilling rig, which overcomes the shortcomings of traditional drilling rigs. Compared with traditional drilling rigs, it has the advantages of low lab...

AI Technical Summary

Problems solved by technology

[0006] 1) The number of drill rods stored in the rod storage box is small: the existing rod storage box is mostly an inclined plane structure, located on the side of the drilling rig, limited by the space volume, and generally can only store 4 to 5 drill rods. During the working process of the drilling rig, when When more drill pipes are needed, workers need to add drill pipes many times, which is time-consuming and laborious

[0007] 2) The rod storage mechanism is complex: another kind of rod storage box is similar to the bullet case type, and the number of storage rods is large, and the drill rods are ejected by spring force. Moving, the spring is prone to fatigue damage after long-term use

[0008] 3) The process of entering and exiting rods is complicated: most of the existing rod storage boxes use hydraulic control to control the entry and exit of rods, which requires more steps to complete the process of releasing or storing rods. A single process takes more time and is not stable. easily damaged

[0009] 4) Poor ability to adapt to complex working conditions: Most of the existing rod storage boxes are fixedly matched with manipulators, and manipulators can only transport drill pipes from fixed tracks or directions, making it difficult to adapt to harsher and more complex working conditions underground
