Description
Technical field
The invention belongs to the coal mining field of mechanical technique, be specifically related to a kind of drill boom device of comprehensive rotation.
Background technology
At present in coal mine machinery equalization field, some drill boom mechanisms commonly used are restricted in the realization action, angle of regulation range is less, overall structure is also huger, and can not realize comprehensive spinning movement, cause work progress to have some setbacks, also dumb, construction operation is restricted, has influenced the progress of construction to a certain extent.
Summary of the invention
The present invention is primarily aimed at existing drill boom structure and exists angle of regulation range little, the problem that overall structure is huge, and provide a kind of and can in 360 degree spaces, realize rotating freely, the drill boom device of comprehensive rotation that overall structure is little.
The present invention addresses the above problem the technical scheme of taking to be:
A kind of drill boom device of comprehensive rotation, comprise the drill boom holder, drill boom, described drill boom comprises the drill boom inner sleeve, the drill boom outer tube, pole inner sleeve and pole outer tube, wherein drill boom inner sleeve and drill boom outer tube are complementary, pole inner sleeve and pole outer tube are complementary, wherein: it also comprises swing I oscillating oil cylinder, the II oscillating oil cylinder, the I revolving bed, the II revolving bed, the III revolving bed, sliding oil cylinder, the I telescopic oil cylinder, the II telescopic oil cylinder, supporting oil cylinder and angling cylinder, described I oscillating oil cylinder is installed on the fixed head of drill boom front end, and the II oscillating oil cylinder is installed on the III revolving bed and with fixed head and is connected; The rear portion of described III revolving bed is provided with external slideway, the II revolving bed is provided with inner slide, the inner slide coupling of III revolving bed by external slideway and II revolving bed is connected and constitutes cavity, in cavity, be provided with sliding oil cylinder, one end of sliding oil cylinder is connected with the III revolving bed, and the other end of sliding oil cylinder is connected with the II revolving bed; Described II revolving bed is connected with the pole inner sleeve with the drill boom inner sleeve, and the drill boom outer tube is connected with the I revolving bed with the pole outer tube, and the I revolving bed is fixed on the drill boom holder; Described I telescopic oil cylinder is located on the drill boom inner sleeve, and an end of I telescopic oil cylinder is connected with the drill boom inner sleeve, and the other end of I telescopic oil cylinder is connected with the drill boom outer tube; Described II telescopic oil cylinder is located on the pole inner sleeve, and an end of II telescopic oil cylinder is connected with the pole inner sleeve, and the other end of II telescopic oil cylinder is connected with the pole outer tube; Described supporting oil cylinder is located on the drill boom outer tube, and an end of supporting oil cylinder is connected with the drill boom outer tube, and the other end of supporting oil cylinder is connected with the I revolving bed; Described angling cylinder is located on the drill boom holder, and an end of angling cylinder is connected with the drill boom holder, and the other end is connected with the I revolving bed.
The present invention adopts technique scheme, utilize 360 degree space frees rotations of the I oscillating oil cylinder of axis normal installation and the II oscillating oil cylinder realization drill boom that axis horizontal is installed, the setting of telescopic oil cylinder simultaneously makes drill boom realize the secondary Telescopic, the setting of supporting oil cylinder makes drill boom realize the oscilaltion function, the setting of angling cylinder makes drill boom realize left and right sides revolute function, therefore compared with prior art, the present invention has adjusting angle advantage big, simple in structure, flexible to operation.
