Embodiment

[0038] A kind of double-link drill pipe pick-up manipulator, such as Figure 1 ~ Figure 4 As shown, it includes a first driving device 1 , a rotating arm 2 , a boom 3 , a connecting rod 4 , a second driving device 5 and a mechanical claw 6 . The specific structure and function of each component are as follows:

[0039] The first driving device 1: is a hydraulic motor, fixed on the rotating arm 2, and its rotating shaft is connected with the connecting rod of the boom 3, so as to realize the rotation of the boom 3 around the rotation center of the first driving device 1, thereby realizing the position adjustment of the drill pipe Variety.

[0040] Rotating arm 2: set on one side of the drilling rig frame through a rotator, and can rotate along point O to realize the change of the inclination angle of the drill pipe.

[0041] Boom 3: connected with the rotating shaft of the first driving device 1, it can rotate around the rotation center of the first driving device 1, and the ot...

Abstract

The invention relates to a double-connecting-rod drill rod picking manipulator, and belongs to the technical field of coal mine drilling rigs. The manipulator comprises a rotating arm capable of rotating in a vertical plane, a big arm is arranged at the other end of the rotating arm, one end of the big arm is connected with a first driving device for driving the big arm to rotate around the axis of the big arm, two parallel connecting rods are hinged to the other end of the big arm, the other ends of the two connecting rods are provided with mechanical claws with clamping power parallel to the big arm, and the manipulator further comprises a second driving device which is connected with the connecting rods and can make the mechanical claws move horizontally. According to the manipulator, a parallel four-connecting-rod mechanism is adopted, longitudinal movement and parallel movement of a drill rod are achieved, the turning radius of the drill rod towards the drilling center is shortened, the turning stability is improved, meanwhile, axial movement of the drill rod is achieved through double-connecting-rod swinging, and by combining the turning function, the space of a stand column can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of coal mine drilling rigs, and relates to a double-link drilling rod picking manipulator. Background technique [0002] With the development of intelligent mining in coal mines, the development of automatic drilling rigs is in the ascendant. The drill pipe picking manipulator is a key component of the automatic drilling rig. Due to the diversity of downhole drilling, such as different hole heights and different hole angles, the downhole space has special characteristics, such as sufficient axial space in the roadway, and horizontal and Insufficient height phase space limits the use of manipulators. Since the drill pipe pick-up manipulator in the prior art cannot take into account both the opening height and the drilling inclination angle, the manipulator cannot effectively and rationally utilize the roadway space. Contents of the invention [0003] In view of this, the purpose of this application is to ...
