Abstract

The invention discloses a drill jumbo mechanical arm of a hydraulic triangular support and a universal rotary structure. The drill jumbo mechanical arm comprises a hydraulic rock drill, a propelling beam, a drill rod, a propelling beam bracket, the universal rotary structure, the telescopic mechanical arm, a mechanical arm base, a mechanical arm triangular-type double-support hydraulic cylinder and a mechanical arm telescopic hydraulic cylinder. Compared with the prior art, the drill jumbo mechanical arm is capable of optimizing and designing a mechanical arm structure, enlarging a working range of the mechanical arm, enabling the mechanical arm and the propelling beam to be more rapidly moved through a double-rotation structure, shortening inter-hole positioning time through the mechanical arm structure, wherein the mechanical arm is large in rigidity, and long in extension, thereby increasing an operation coverage area, improving efficiency of rock drilling, shortening a constructionperiod, and reducing construction cost, and has a popularization and application value.

Description

technical field [0001] The invention relates to an engineering machine, in particular to a mechanical arm of a rock drilling jumbo with a hydraulic triangular support and a universal rotary structure. Background technique [0002] The rock drilling jumbo is a mobile construction equipment equipped with several hydraulic rock drills for simultaneous drilling operations. It is mainly used in the drilling and blasting construction of water conservancy and transportation tunnels. At present, the common rock drilling rigs in engineering include tire-type and crawler-type rigs, as well as digging-type and rail-type rigs. Rail-type rock drilling rigs need to lay tracks at the construction site in advance, and their body structures are generally gantry-type, so they are also called gantry-type rock drilling rigs. This kind of rock drilling jumbo generally has two to three workbenches, and more than ten rock drilling machines can be installed at most, and the lower part is connected...
