The beneficial effects of the utility model are: 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) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
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) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.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.
