Abstract

The invention discloses a rock-core drill holder which comprises a base, a left-side rotating shaft, a right-side rotating shaft, a left arm and a right arm. Each of the left-side rotating shaft and the right-side rotating shaft is mounted on the base through a pair of bearings, and one ends of the left arm and the right arm are mounted on the left-side rotating shaft and the right-side rotating shaft respectively while the other ends of the same are hinged to a clamping tile used for clamping a drilling rod; the left-side rotating shaft or the right-side rotating shaft is driven to rotate through a hydraulic oil cylinder, and a connecting rod used for enabling the left-side rotating shaft and the right-side rotating shaft to synchronously and rotate in different directions is arranged between the left-side rotating shaft and the right-side rotating shaft. According to the rock-core drill holder, the clamping tile is reliable in clamping, so that safety in use of the rock-core drill holder is guaranteed.

Description

technical field [0001] The invention relates to a hydraulic rock core drilling equipment, in particular to a core drill holder. Background technique [0002] The gripper is a part of the hydraulic core drilling rig for loading and unloading the drill pipe. It is characterized by high operating frequency, reliable clamping and convenient operation. Most of the grippers used on hydraulic core drilling rigs are hydraulic elastic grippers or normally closed grippers. Holder. [0003] For the hydraulic elastic clamp, the clamping and loosening of the slips are realized by hydraulic pressure. When the oil inlets of the hydraulic cylinders on both sides are respectively supplied with high-pressure oil, the slips follow the movement of the piston and move closer to the center to clamp the drilling tool; change The high-pressure oil enters, and the slips deviate from the center to loosen the drilling tool. This type of holder has a relatively simple structure, but the clamping forc...
