Hydraulic drill carriage drill arm moving fulcrum metamorphic mechanism

Abstract

The invention discloses a hydraulic drill carriage drill arm moving fulcrum metamorphic mechanism; one end of a hydraulic oil cylinder is hinged with a machine body while the other end of the hydraulic oil cylinder is hinged with a big arm; a deflection shed rod support is connected with the machine body, the deflection shed rod is hinged with the deflection shed rod support, a deflection shed rod is hinged with one end of a big arm connection rod, the other end of the big arm connection rod is hinged with the big arm, a big arm sliding block is mounted on the tail part of the big arm, the big arm sliding block slides on a sliding rail, the sliding rail is mounted on the machine body, and a sliding rail limiting block is mounted at the top of the sliding rail. The metamorphic mechanism is applied to the hydraulic drill carriage drill arm for adequately and flexibly solving the problems of the conventional hydraulic drill arm adopting the simple drill arm structure, the position in the pitching range and key point position cannot reach the requirement, so that the working angle and transporting and folding operation are inconvenient. The hydraulic drill carriage drill arm moving fulcrum metamorphic mechanism has big working angle, the special position can be directly positioned, and the hydraulic drill carriage drill arm moving fulcrum metamorphic mechanism can solve the defect that the conventional mechanism cannot abundantly lift the big arm when the arm is lifted and transported for the hydraulic drill carriage.

Description

technical field [0001] The invention relates to the field of construction machinery mechanisms, in particular to a mobile fulcrum metamorphic mechanism of a hydraulic drilling rig. Background technique [0002] Hydraulic drilling rigs are widely used. How to increase the swing angle of the working parts of the hydraulic drilling rig and minimize the transport size is the key to expanding the working area of ​​the drilling rig and increasing the efficiency of the drilling rig. The traditional hydraulic drilling rig generally adopts a simple triangular rod type. Rotational range and folded state are generally poor. Contents of the invention [0003] In view of the above-mentioned problems, the object of the present invention is to provide a mobile fulcrum metamorphic mechanism for the drill arm of a hydraulic drilling rig. [0004] The technical solution of the present invention is: the moving fulcrum mechanism of the hydraulic drilling rig, including the body, the hydrauli...
