Abstract
The invention relates to an excavator, in particular to an excavator for earthwork stepped construction of an underground passage. The excavator for earthwork stepped construction of the underground passage comprises a frame, wherein the front end of the frame is connected with an outer swing arm; an outer swing arm cylinder is connected between the outer swing arm and the frame. The excavator is characterized in that an inner swing arm is sleeved in the outer swing arm; a telescopic cylinder is connected between the outer swing arm and the inner swing arm; the front end of the inner swing arm is connected with a shaking rod; the rear ends of the shaking rod and the inner swing arm are connected with a shaking rod cylinder; the frame is provided with a conveying bracket; the conveying bracket is provided with a conveying belt. The excavator has the beneficial effects that far and near stepped underground passages can be excavated; meanwhile, the excavated earthwork and the like can be transported out automatically; the excavator has high working efficiency and high safety, and is convenient to operate, and great convenience is brought to engineering construction of underground passages.
Description
(1) technical field
The present invention relates to a kind of excavator, particularly a kind of underground passage earthwork ladder construction excavator.
(2) background technology
Along with the continuous progress of expanding economy and society, resource, in continuous consumption, need to be developed the resources such as increasing colliery, iron ore; And urbanization, also in continuous quickening, needs the underground passage of building also to get more and more.When offering underground passage, what mostly use at present is hand digging method, and hand digging efficiency is extremely low, within one day, does not also carry out several meters, and not only cost is high, also seriously delays the duration.Now, some building site brings into use excavator to excavate, but equally also there is certain problem: the excavation to underground passage, there is regulation in country, dig into a segment distance and will carry out hole inner support, having supported a part excavates forward again, this excavation is exactly staged construction method, but excavator is when excavating, if swing arm is long, the place that will encounter fuselage during recovery and support, if too short, when fuselage cradle in support highland time, will reach and need above the earthwork of excavating.The how outside transportation of the earthwork of excavating out in addition, is also a great problem.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides the underground passage earthwork ladder construction that a kind of efficiency is high, easy to operate, safe, swing arm is scalable, can the earthwork of excavating be transported simultaneously excavator.
The present invention is achieved through the following technical solutions:
A kind of underground passage earthwork ladder construction excavator, comprise frame, frame front end is connected with outer swing arm, between outer swing arm and frame, be connected with outer swing arm cylinder, it is characterized in that: in described outer swing arm, be arranged with interior swing arm, between outer swing arm and interior swing arm, be connected with telescoping cylinder, interior swing arm front end connects stick shaker, stick shaker and interior swing arm rear end are connected with stick shaker cylinder, and frame is provided with transfer gantry, and transfer gantry is provided with conveyer belt.
Described stick shaker front end is connected with bucket, and bucket and stick shaker rear end are connected with bucket cylinder.
Described conveyer belt rear end is connected with driving wheel, and front end is connected with follower, and centre is provided with some support rollers.
Described frame is installed on chassis by turning rack, between frame and chassis, is connected with lift cylinders, between turning rack and chassis, steering cylinder is installed.
Described outer swing arm cylinder, telescoping cylinder, stick shaker cylinder, bucket cylinder, lift cylinders are connected with hydraulic control system by walk motor with hydraulic pressure respectively with steering cylinder, and chassis is installed on tire, and electric-control system and gearbox are installed in frame.
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) accompanying drawing explanation
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.
(5) specific embodiment
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.
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 shakers 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, dug 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 rotations, thereby the earthwork is directly transported.In-plant cubic metre of earth, with regard to directly interior swing arm 4 is regained in outer swing arm 2, excavate just passable.When running into hardpan, bucket 10 can be unloaded, change quartering hammer, break into pieces after hardpan, then change bucket 10 and excavate.
