Complexity of the whole structure is greatly simplified, manufacturing costs are reduced, and installation and dismantling difficulty is lowered.
Description
Technical field
The present invention relates to coal mine development machine equipment, be specially a kind of development machine stretching structure.
Background technology
The cutting units stretching structure of current domestic telescopic development machine generally adopts the structure shown in Fig. 1, and its structure exists very large defect and deficiency, is specifically described below:
1) original structure complicated, manufacture, assembly difficulty is large: original structure is made up of the inner core that stretches, outer telescopic tube and flexible protection cylinder and related accessories etc.Three cylindrical shells slide mutually, and cylindrical shell manufacturing procedure is complicated, tolerance fit and the roughness that need ensure fitting face, need carry out during assembling according to correct order.
2) higher, the maintenance difficult of original structure fault rate: original structure often occur the faults such as drum surface wearing and tearing, cylindrical shell bad seals, maintenance and renewal part time more difficult.
Stressed poor under the state of stretching out of original structure.
Summary of the invention
The object of the invention is to for above-mentioned defect, a kind of development machine stretching structure that a kind of structure is simple, easy to maintenance, practical is provided.
The object of the invention is to realize in the following manner:
A kind of development machine stretching structure, comprises the outer telescopic tube of suit and flexible inner core, is provided with the cut telescopic oil cylinder regulating collapsing length between outer telescopic tube and flexible inner core, and be provided with cutting motor in flexible inner core, outer telescopic tube rear end is connected with rear Connection Block.
Dust guard is provided with between outer telescopic tube and flexible inner core.
Dust guard comprises the mud-scraping ring being arranged on outer telescopic tube front end, and mud-scraping ring baffle plate is fixed on mud-scraping ring on outer telescopic tube.
Stretch and between inner core and outer telescopic tube, be provided with two groups of sliding bearings.
The arranged outside of flexible inner core has flexible lead, outer telescopic tube is provided with corresponding pilot hole.
Rear Connection Block is hinged on development machine panoramic table, and panoramic table is also hinged with cut hoist cylinder, and the other end and the outer telescopic tube of cut hoist cylinder are hinged.
Relative to prior art, structural entity stressed effect of the present invention is good, and intensity is high, ensures the normal operation of complete machine, reduces equipment fault point.This novel cutting units stretching structure maintain and replace is simple, convenient, and structure is simple, compact, enormously simplify integrally-built complexity, reduces manufacturing cost and installation, disassembles difficulty.
Accompanying drawing explanation
Fig. 1 is former cutting units stretching structure sectional view.
Fig. 2 is structure sectional view of the present invention.
Fig. 3 is using state reference diagram of the present invention.
In figure, 1-cut reductor; 2-mud-scraping ring baffle plate; 3-mud-scraping ring; 4-sliding bearing; 5-flexible inner core; 6-cutting motor; 7-outer telescopic tube; 8-rear Connection Block; 9-cutterhead assembly; 10-telescopic cantilever section; 11-cut telescopic oil cylinder; 12-flexible lead; 13-cut hoist cylinder; 14-development machine panoramic table; .
Detailed description of the invention
As shown in Fig. 2-Fig. 3, Fig. 2 is the A-A sectional view of Fig. 3, of the present inventionly realizes principle: it is inner that cutting motor 6 is bolted on flexible inner core 5; Flexible inner core 5 is connected and fixed with cut reductor 1; Cut reductor 1 and telescopic cantilever section 10 are connected and fixed; Telescopic cantilever section 10 and cutterhead assembly 9 are connected and fixed, and above five parts are synchronized with the movement.
Outer telescopic tube 7 inside is provided with two groups of sliding bearings 4; Outer telescopic tube 7 and rear Connection Block 8 are bolted fixing; Mud-scraping ring 3 plays dust-proof effect; Mud-scraping ring 3 is bolted on outer telescopic tube 7 by mud-scraping ring baffle plate 2.
One end of cut telescopic oil cylinder 11 is hinged on flexible inner core 5, the other end is hinged on outer telescopic tube 7, is used for regulating collapsing length; Flexible lead 12 is fixed on flexible inner core 5, and outer telescopic tube 7 arranges the pilot hole corresponding with it, and flexible lead 12 can be free to slide in pilot hole with flexible inner core 5; Cut hoist cylinder 13 one end is hinged on outer telescopic tube 7, and the other end is hinged on panoramic table 14; Rear Connection Block 8 is also hinged on development machine panoramic table 14.
Cut telescopic oil cylinder 11 provides power for realizing cutting units expanding-contracting action and controls stroke.Flexible lead 12 is used for carrying out guide effect to cutting units expanding-contracting action.Cut hoist cylinder 13 is used for realizing the lifting action of cutting units.
When cut telescopic oil cylinder 11 carry out stretching out and or retracting action time; flexible inner core 5 is along flexible lead 12 and outer telescopic tube 7 relative sliding; stretch out under the lubrication and protection of sliding bearing 4 or bounce back; drive cut reductor 1, telescopic cantilever section 10, cutterhead assembly 9 synchronously stretch out or bounce back, realize the expanding-contracting action of cutting units.
When cut hoist cylinder 13 carries out expanding-contracting action, outer telescopic tube 7 is driven to rotate, and then drive cut reductor 1, telescopic cantilever section 10 and cutterhead assembly 9 to rotate by flexible inner core 5, realize the lifting of cutterhead assembly 9, and do not affect the stretching motion of cutting units.
The invention has the beneficial effects as follows:
One, after stretching structure is placed in transmission device by the present invention, structure is simple, compact, enormously simplify integrally-built complexity, reduces manufacturing cost and installation, disassembles difficulty.
Two, structural entity stressed effect of the present invention is good, and intensity is high, ensures the normal operation of complete machine, reduces equipment fault point.
Three, maintain and replace of the present invention is simple, convenient.
