Embodiment 1

[0066] Such as Figure 1 to Figure 8 As shown, the present embodiment provides an automatic rod-adding device for an underground tunnel drilling machine in a coal mine, including a feeding device 1, a power head 2 and a holder 3, and the power head 2 can move along the linear slide rail of the feeding device 1 and The power head 2 clamps the active drill pipe 4, and the active drill pipe 4 is coaxially opposite to the holder 3; the power head 2 provides the rotary torque for the drilling machine; The feeding device 1 reciprocates in the direction of the linear slide rail, that is, provides the feeding and pulling force for the drilling tool; the active drill rod is clamped by the power head 2 to transmit the torque and propulsion to the drilling tool in the hole; the angle adjustment device 5 can Adjust the azimuth and the inclination of the main shaft; the clamper 3 is used to clamp the drilling tool in the hole, and cooperate with the power head 2 to realize the unscrewing a...

Embodiment 2

[0093] This embodiment provides a method for adding rods of an automatic rod adding device for an underground tunnel drilling rig in a coal mine, including the following steps:

[0094] Step 1, return the power head of the drilling rig to the rear end of the feeding device;

[0095] Step 2, keep the drill pipe magazine push-out cylinder fully retracted;

[0096] Step 3, operate the lifting mechanism to lift the drill pipe to be added to the top of the drill pipe warehouse;

[0097] Step 4, fully retract the second telescopic oil cylinder and fully extend the first telescopic oil cylinder, send the claw mechanism to the drill pipe warehouse, and coincide with the axis of the drill pipe to be added;

[0098] Step 5, extend the gripper cylinder to tighten the front and rear claws to tighten the drill pipe;

[0099] Step 6, fully retract the first telescopic oil cylinder so that the claw mechanism moves to coincide with the axis of the drilling rig power head with the drill pipe...

Embodiment 3

[0106] This embodiment provides a method for repairing rods with the automatic rod adding device for the coal mine underground tunnel drilling rig in Embodiment 1, which specifically includes the following steps:

[0107] Step 1, when it is necessary to fill the drill pipe chamber with drill pipes, operate the extended and ejected oil cylinder, the inner chamber rotates around the pin shaft, and the upper opening of the inner chamber is completely exposed;

[0108] Step 2, manually fill the drill pipe in the inner chamber;

[0109] Step 3: Operate the retraction and push-out oil cylinder, and the drill pipe inner chamber rotates around the pin shaft and returns to the outer chamber, and maintains a vertical state.

Abstract

The invention discloses an automatic rod adding device and a rod adding method for a coal mine underground tunnel drilling rig, comprising a feeding device, a power head, a gripper, an active drill rod, a drill rod storehouse and a mechanical arm; the mechanical arm includes a mechanical arm casing, a first A driving unit, an inner sleeve of a mechanical arm, a claw mechanism and a first telescopic oil cylinder; the drill pipe warehouse includes an outer warehouse, an inner warehouse, a lifting mechanism, and an ejection cylinder; the mechanical arm can hold the drill pipe from the drill pipe warehouse and send it to the into the center line of the drilling hole, and cooperate with the active drill pipe of the power head to realize the addition of the drill pipe; the gripper mechanism has a self-compensating floating function, which can compensate for the mismatch between the make-up speed and the feed speed during manual operation. The invention is equipped with a chuck-type power head and a single clamper structure, which has high automation, simple and reliable control system, simple operation, and is easy to integrate with existing conventional drilling rigs, and can meet the requirements of drilling rods with an inclination angle of the main shaft of the drilling rig within the range of ±90°. catch.

Description

technical field [0001] The invention belongs to the technical field of coal mine drilling rig equipment, and in particular relates to an automatic rod adding device and a rod adding method for an underground tunnel drilling machine in a coal mine. Background technique [0002] Coal mine underground tunnel drilling rigs are widely used in coal mine underground water exploration, gas drainage, roof and floor grouting, geological structure exploration, large-diameter pressure relief and other constructions. Unlike ground construction, due to complex conditions such as narrow underground space in coal mines, complex drilling technology, large drilling angle range, and large equipment power capacity, there are very few automatic rod adding devices that can be successfully popularized and applied. Most coal mine tunnel drilling rigs still use Manual loading of drill pipe. The construction personnel need to manually send the drill pipe to the middle or rear of the feeding device, ...
