Embodiment 1

[0081] This embodiment provides an automatic loading and unloading drill pipe device for a coal mine tunnel drilling machine, which is characterized in that it includes a rod storage car 100 , a rod adding car 200 and a manipulator 300 .

[0082] The pole-adding vehicle 200 includes a first crawler belt assembly 201 , a horizontal first base plate 202 fixed on the first crawler belt assembly 201 , and two parallel and opposite vertical stepped fixing plates 203 fixed on the first base plate 202 , two vertical first oil cylinders 204 fixed on the first bottom plate 202 and located between the two stepped fixed plates 203, two parallel opposite and step-shaped oil cylinders respectively fixed on the two first oil cylinders 204 The fixed plate 203 is parallel to the stepped movable plate 205 and the first oil cylinder 204 can drive the stepped movable plate 205 to reciprocate vertically up and down; The highest step of the fixed plate 203 is connected with a V-shaped bracket 206;...

Embodiment 2

[0107] This embodiment provides a control method for an automatic loading and unloading drill pipe device for a coal mine tunnel drilling rig, including:

[0108] Step 1, the process of adding rods:

[0109] Step 1.1, arrange the rod storage car, the rod adding car and the manipulator installed on the drilling rig in sequence, arrange the manipulator so that the rotating beam is parallel to the V-shaped bracket, and adjust the fourth oil cylinder to rotate the gripper to reach the position of the V-shaped bracket It can also rotate to the position of the holder to place the drill pipe while grabbing the drill pipe;

[0110] Step 1.2, control the contraction of the second oil cylinder in the rod storage car to make the rotating bottom plate tilt to the lateral gap side, and the drill pipe automatically rolls to the step groove of the first step of the stepped fixed plate of the rod adding car;

[0111] Step 1.3, control the first oil cylinder to drive the stepped movable plate...

Abstract

The invention discloses an automatic loading and unloading drill pipe device and control method for a coal mine tunnel drilling rig. The device includes a rod storage car, a rod adding car and a manipulator; the rod adding car includes a first crawler belt assembly, a first bottom plate, and a stepped fixing plate , the first oil cylinder, step-shaped movable plate, V-shaped bracket, adjustment plate, guide rail, servo motor, and lead screw, which can move the drill pipe output by the rod storage car to the designated position in sequence for the manipulator to grab; the rod storage car includes The second crawler assembly, the second frame, the rotating bottom plate, the second oil cylinder, the bolt, and the third oil cylinder can store a certain amount of drill pipes; the manipulator includes a mounting frame, a fourth oil cylinder, a sliding frame, a rotating beam, a swing arm, The gripper, the first cycloidal motor, the second cycloidal motor, and the third cycloidal motor can transport the drill pipe output from the rod adding car to the designated position on the drilling rig and put the drill pipe back into the rod storage car during the unloading process . The invention realizes the continuity of the process of loading and unloading drill pipes, and improves the automation level of loading and unloading drill pipes of coal mine tunnel drilling rigs.

Description

technical field [0001] The invention belongs to the technical field of drill pipe loading and unloading, and relates to an automatic loading and unloading drill pipe device and a control method for a coal mine tunnel drilling machine. Background technique [0002] Automation and intelligence are the main development directions of the coal industry in recent years. Using equipment with automation and intelligent functions to replace manual labor can not only solve the high labor intensity of workers and the resulting safety problems, but also effectively alleviate the increasingly prominent problem of "difficulty in recruiting workers" in the coal industry. Automation and intelligent equipment will lead the coal industry to achieve high-quality development and represent a new direction for the development of equipment in the coal industry. [0003] The automation and intelligence of coal mine tunnel drilling rigs must be inseparable from the automatic loading and unloading d...
