The invention has the beneficial effects as follows: can excavate the stepwise lower channel of far and near distance, the earthwork of excavating etc. can be transported automatically simultaneously; Operating efficiency is high, easy to operate, safe, very big facility is provided to the engineering construction of underground passage.
(4) brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is structural representation of the present invention;
In figure, 1 frame, 2 outer swing arms, 3 outer swing arm cylinders, 4 interior swing arms, 5 telescoping cylinders, 6 stick shakers, 7 stick shaker cylinders, 8 transfer gantries, 9 conveyer belts, 10 buckets, 11 bucket cylinders, 12 driving wheels, 13 followers, 14 support rollers, 15 turning racks, 16 chassis, 17 lift cylinders, 18 steering cylinders, 19 walk motor with hydraulic pressures, 20 hydraulic control systems, 21 tires, 22 electric-control systems, 23 gearboxes, 24 tailstocks, 25 rotating shafts, 26 telescopic oil cylinders.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises frame 1, frame 1 front end is connected with outer swing arm 2, between outer swing arm 2 and frame 1, be connected with outer swing arm cylinder 3, in outer swing arm 2, be arranged with interior swing arm 4, between outer swing arm 2 and interior swing arm 4, be connected with telescoping cylinder 5, interior swing arm 4 front ends connect stick shaker 6, and stick shaker 6 is connected with stick shaker cylinder 7 with interior swing arm 4 rear ends, frame 1 is provided with transfer gantry 8, and transfer gantry 8 is provided with conveyer belt 9.Stick shaker 6 front ends are connected with bucket 10, and bucket 10 is connected with bucket cylinder 11 with stick shaker 6 rear ends.Conveyer belt 9 rear ends are connected with driving wheel 12, and front end is connected with follower 13, and centre is provided with some support rollers 14.Frame 1 is installed on chassis 16 by turning rack 15, between frame 1 and chassis 16, is connected with lift cylinders 17, between turning rack 15 and chassis 16, steering cylinder 18 is installed.Outer swing arm cylinder 3, telescoping cylinder 5, stick shaker cylinder 7, bucket cylinder 11, lift cylinders 17 and steering cylinder 18 are connected with hydraulic control system 20 by walk motor with hydraulic pressure 19 respectively, and chassis 16 is installed on tire 21, and electric-control system 22 and gearbox 23 are installed in frame 1.Transfer gantry 8 rear portions are provided with tailstock 24, and tailstock 24 is connected by rotating shaft 25 with transfer gantry 8, are provided with the telescopic oil cylinder 26 rotating up and down for tailstock 24 between tailstock 24 and transfer gantry 8.
Adopt a kind of underground passage earthwork ladder construction excavator of the present invention, while excavating the earthwork at a distance, operation hydraulic control system 20, telescoping cylinder 5 is protracted, thereby in promoting, swing arm 4 moves ahead, interior swing arm 4 drives stick shaker 6 and the bucket 10 arrival assigned address that moves ahead, handling outer swing arm cylinder 3 reclaims, outer swing arm 2 is sunk, stick shaker cylinder 7 and bucket cylinder 11 are protracted respectively, thereby make stick shaker 6 and bucket 10 times curved, dig the earthwork, handling telescoping cylinder 5 reclaims, make bucket 10 be placed in transfer gantry 8 front end tops, handle bucket cylinder 11, bucket 10 is upspring, the soil digging out falls into conveyer belt 9 front ends, driving wheel 12 drives conveyer belt 9 to rotate, thereby the earthwork is directly transported.In-plant cubic metre of earth, with regard to directly interior swing arm 4 is regained excavate in outer swing arm 2 just passable.In the time running into hardpan, bucket 10 can be unloaded, change quartering hammer, break into pieces after hardpan, then change bucket 10 and excavate.In the time that excavator is walked in underground passage, if run into turning, telescopic oil cylinder 26 can be retracted, tailstock 24 falls under rotating shaft 25 effects, can reduce the length of whole excavator, is convenient to turn round.
