Problems solved by technology

[0005] Beneficial effects of the present invention: the present invention uses the metamorphic mechanism in the technology of the drill arm of the hydraulic drilling rig. Its working angle is large, and the special position can be directly positioned, which can solve the problem that the traditional mechanism cannot move the hydraulic drilling rig when the arm needs to be transported. Disadvantages of fully raised arms

Embodiment Construction

[0007] Now in conjunction with accompanying drawing, the present invention is described in further detail.

[0008] Such as figure 1 As shown, the extension arm 3 is hinged with the body 1, the main arm 4 is hinged with the extension arm 3, one end of the hydraulic cylinder 2 is hinged with the body 1, and the other end is hinged with the main arm 4. Installed on extension arm 3.

[0009] Before the transformation, the main arm 4 and the extension arm 3 form a whole through the hinge point and the positioning rod 6 under the action of gravity. When the hydraulic cylinder 2 is extended, the extension arm 3 is in contact with the transformation rod 5, and the position is limited so that it cannot Continue to rise, the main arm 4 breaks away from the positioning rod 6 and continues to rise. Since the fulcrum of the main arm is displaced to become the hinge point with the extension arm at this time, the radius of rotation is reduced and the swing speed is accelerated, which can s...

Abstract

The invention discloses a hydraulic drill carriage drill arm adding connecting rod metamorphic mechanism. The hydraulic drill carriage drill arm adding connecting rod metamorphic mechanism comprises an engine body, a hydrocylinder, an adding arm, a main arm, a metamorphic rod and a positioning rod; the adding arm is hinged to the engine body, the main arm is hinged to the adding arm, one end of the hydrocylinder is hinged to the engine body, the other end of the hydrocylinder is hinged to the main arm, the metamorphic rod is installed on the engine body, and the positioning rod is installed on the adding arm. The hydraulic drill carriage drill boom adding connecting rod metamorphic mechanism has the advantages that the metamorphic mechanism with a big operating angel and capability to positioning directly in a special position is applied to the hydraulic drill carriage drill arm technology, and the defect that a traditional mechanism is unable to uplift a big arm sufficiently when a lifting arm of the hydraulic drill carriage needs to be transported is overcome.

Description

technical field [0001] The invention relates to the field of engineering machinery mechanisms, in particular to a hydraulic drilling rig drill arm increasing connecting rod metamorphic mechanism. 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 scenarios. Traditional hydraulic drilling arms usually use 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-mentioned problems, the obje...
