Description
Technical field
The utility model relates to fill (anchor) unit to rubber-tyred drill carriage, crawler jumbo, drill loader group, rock bolting jumbo, brill
It is comprehensive Deng comprehensive unit heading equipment, more particularly to crawler jumbo, coal mine rock gangway drill loader group, brill dress (anchor) unit etc.
Unit equipment.
Background technique
In comprehensive unit drivings such as rubber-tyred drill carriage, crawler jumbo, drill loader group, rock bolting jumbo, brill dress (anchor) units
Commonly use telescopic arm drilling anchor structure in equipment to have some limitations, be mainly manifested in: not only gap is big for drilling anchor structure, shakes
Greatly, external setting adjustment inter space device is needed, and drilling anchor yield strength of structure is inadequate, part size generally requires to increase, add
Slightly；Not only increase manufacture material and time cost, but also will affect the working performance of drilling anchor structure, reduces working efficiency.
Utility model content
For the problems of above-mentioned drilling anchor structure of telescopic arm in the prior art, the utility model is mentioned with a kind of gap
It is small, without shaking, do not need to add and external adjust device, so that it may ensure telescopic arm job stability, improve drilling anchor knot of operating efficiency
Structure.
The technical problems to be solved in the utility model is adopted the technical scheme that: drilling anchor structure of the telescopic arm includes
Stretch inner arm and flexible outer arm, is arranged at intervals with upper fixed seat on the flexible inner arm outer surface, and inner arm one end of stretching has a left side
Fulcrum bearing is provided with oil cylinder between flexible inner arm and flexible outer arm, and described oil cylinder one end is connected with left fulcrum bearing, in flexible
Guide sleeve is provided in arm, upper guide sleeve has vertically-guided plate along axial, and oil cylinder top is axially disposed guide groove, hangs down
Straight guide plate and guide groove activity cooperate, and guide groove is fixed on flexible inner arm inner surface, and outer arm one end of stretching has right bearing
Seat, oil cylinder is interior to be arranged piston rod, and piston rod one end is stretched out outside oil cylinder to be connected with right fulcrum bearing, is provided with lower guiding on flexible outer arm
Set, is provided with sealing element between lower guide sleeve and oil cylinder, and lower guide sleeve is arranged at intervals with lower fixed seat on outer surface, flexible
Outer arm radially opposite sides are provided with the Horizontal limiting plate of medial surface Yu lower guide sleeve appearance face contact, and flexible inner arm is supported on horizontal limit
On the horizontal plane of position plate.
Inside and outside telescopic arm cross section described in the utility model uses circular configuration, and machining accuracy can guarantee, substantially increases
Fit-up gap makes telescopic arm stable action, without shaking.After transparent cover and sealing element 9 are installed in advance, then oil cylinder 6 is packed into and is stretched
In contracting outer arm 2, the piston rod of oil cylinder is connected by pin shaft 12；The flange base 3 of 6 front end of oil cylinder and flexible inner arm 1 pass through screw rod
It is connected and fixed.When the movement of oil cylinder 6 drives flexible inner arm 1 to be moved forward and backward, vertical limit plate 7 and Horizontal limiting plate 8 can make in flexible
The holding of arm 1 moves linearly in one direction, so that it is guaranteed that double swerve will not occur for flexible inner arm.
Flexible inner arm described in the utility model and flexible outer arm are under oil cylinder effect, due to having Horizontal limiting plate and vertical limit
The guiding role of position plate and upper and lower guide sleeve can make flexible inner arm in flexible outer arm without separately setting adjustment device in outside
Make the linear movement in a direction, and movement, steadily without shaking, the utility model is compact-sized, manufactures easy to use, mutually shifting
It is dynamic steady, drilling anchor mechanical stability can be improved, improve job execution efficiency.
