The movable fulcrum metamorphic mechanism of the small arm of the hydraulic drilling rig

Abstract

The invention discloses a hydraulic drill carriage forearm moving fulcrum metamorphic mechanism; a big arm is hinged to a machine body, a big arm oil cylinder is hinged to the machine body, the big arm oil cylinder is hinged to the big arm, a forearm hinging point is mounted on the forearm, the forearm hinging point slide in a big arm sliding chute, a forearm hinging point connection rod is connected with the forearm hinging point and a forearm chute sliding block, a big arm oil cylinder top block is connected with the forearm chute sliding block, and the top of big arm oil cylinder top block is connected with the big arm through a spring. The hydraulic drill carriage forearm fulcrum metamorphic mechanism has benefits that the metamorphic mechanism is used in hydraulic drill carriage arm technology, the work angle is big, the special position can be directly positioned, the working forearm can continuously shrink inwards based on original base through the metamorphic mechanism when the working forearm shrinks inwards adequately, and the hydraulic drill carriage forearm moving fulcrum metamorphic mechanism can achieve the working position and folding state which are not achieved by the general agency drill arm.

Description

technical field [0001] The invention relates to the field of engineering machinery mechanisms, in particular to a movable fulcrum metamorphic mechanism of a small arm of a hydraulic drilling rig. Background technique [0002] All kinds of hydraulic drilling rigs are widely used in blast hole drilling operations in metallurgy, railways, mines, building materials, highways and other projects. Among them, the key to determine the working angle, working range, and transport volume of the hydraulic drilling rig is the transmission structure of the drill arm. The flexible, stable, and small-sized drilling arm mechanism can play a huge role in the above-mentioned scenarios. The traditional hydraulic drilling arm usually adopts a simple The drill boom structure cannot meet the requirements in the swing range and the positioning of key points, which causes inconvenience in working angle, transportation and folding. Contents of the invention [0003] In view of the above existing p...
