Embodiment 1

[0030] The utility model relates to a drilling rig with an automatic dismounting device for drill rods, which includes a working vehicle and a frame system. like Figure 1-2 As shown, the frame system includes a frame 1, a main drill pipe 2, an elevator 3 and a manipulator.

[0031] A slide mechanism is provided on the side wall of the frame 1, and the slide mechanism includes a slide rail 6, a slide block 10 and a third pushing mechanism. The slide rails 6 are fixed on the side wall of the frame 1, and there are two slide rails arranged vertically and at intervals in the horizontal direction. There are two sliders 10 spaced up and down, and the two sliders 10 are respectively stuck on the slide rails 6 . The third pushing mechanism is fixed on the side wall of the frame 1, and includes a third hydraulic cylinder 91 and a third hydraulic rod 92 located below the lower slider 10, and the top end of the third hydraulic rod 92 is fixedly connected with the bottom end of the low...

Embodiment 2

[0040] Embodiment 2 A drilling rig with an automatic disassembly and assembly device for drill rods

[0041] This embodiment has the same work vehicle and frame system as the structure of Embodiment 1, the only difference is that a plurality of protrusions are distributed on the inner wall of the arc-shaped plate portion of the side wall 41 of the gripper 4, when the gripper 4 and When the drill rod 14 is in contact, the protrusion can increase the contact friction between the arc-shaped plate and the drill rod 14 to prevent the drill rod 14 from slipping. Certainly, the protrusions may also be other structures capable of increasing frictional force, such as a grid-shaped surface, a corrugated surface, and the like.

Embodiment 3

[0042] Embodiment 3 A drilling rig with an automatic drill pipe dismounting device

[0043] This embodiment has the same work vehicle and frame system as that of Embodiment 1, the only difference is that a contact sensor is provided on the inner wall of the arc-shaped plate part of the side wall 41 of the gripper 4, and the contact sensor is used to detect For the positional relationship between the gripper 4 and the drill rod 14, the contact sensor transmits a signal to the control unit when the drill rod 14 contacts the drill rod 14, and the control unit controls the first hydraulic cylinder 71 to stop working.

Abstract

The invention discloses a drilling machine with an automatic drill stem disassembling device. The drilling machine comprises a machine frame and a main drill stem, wherein a lift and a mechanical arm are fixed on the machine frame, the lift is used for lifting a drill stem when the drill stem is assembled and disassembled, and the mechanical arm is used for firmly grasping the drill stem when the drill stem is assembled and disassembled; a sliding mechanism which can slide vertically is fixed on the side wall of the machine frame; the mechanical arm comprises tongs, a rotary end and a rotary arm fixedly connected with the tongs; a first pushing mechanism used for changing the opening and closing radius of the tongs is fixed on the tongs; the fixed end of the rotary arm is fixedly connected with the sliding mechanism, and a second pushing mechanism used for enabling the rotary arm to rotate around the fixed end is fixed on the rotary arm. According to the drilling machine, the lift is used for lifting the drill stem, the mechanical arm can move horizontally and vertically, and is used for firmly grasping the drill stem to complete automatic disassembly or assembly of the drill stem and the main drill stem, labor is saved, and body safety of constructors is guaranteed. The drilling machine is suitable for various engineering drillers.

Description

technical field [0001] The invention relates to an engineering drilling rig, in particular to a drilling rig with an automatic dismounting device for drill rods. Background technique [0002] During the construction process of engineering drilling rigs, according to different conditions, it is necessary to manually install or disassemble drill pipes frequently. The manual labor intensity is high. Repeated installation and disassembly of drill pipes may cause equipment damage due to construction personnel's misoperation, which is more serious. It will cause construction personnel casualties, and then cause serious economic losses and personal safety issues. [0003] Chinese invention patent (application publication CN103541670A) discloses "an automatic loading and unloading device for horizontal directional drilling rig drill pipes", including drill pipe boxes and drill pipes, grippers, vertical mounts, gripper cylinders, horizontal mounts, vertical guide rods, Horizontal gu...
