Abstract
A kind of excavator repacking hydraulic breaking hammer worked continuously forward in restricted clearance, it is characterized in that, including the swing arm being arranged on excavator body, and bucket arm cylinder and hydraulic pressure hammer body, described bucket arm cylinder lower end is fixed on swing arm, upper end is simultaneously connected with rocking bar and connecting rod by link connector pin axle, described swing arm upper end connects hydraulic pressure hammer body by connecting bearing pin under scraper bowl, swing arm rocking bar hinge hole it is additionally provided with on swing arm upper end, the described rocking bar other end connects bearing pin by dipper rocking bar and is connected on swing arm through newly-increased hinge hole, the described connecting rod other end connects hydraulic pressure hammer body by connecting bearing pin on scraper bowl.The oil circuit of described hydraulic pressure hammer body is connected by the bucket arm cylinder hydraulic tube arranged along swing arm upper limb.The problem solving to be unable to reach continuous horizontal operation forward when tunnel operation so that hydraulic breaking hammer can be crushed to be positioned at the rock in the range of excavator " dead ahead " even " front upper place " in restricted clearance.
Description
Technical field
This utility model relates to hydraulic breaking hammer, especially with a kind of restricted clearance in work continuously forward excavator repacking
The structure of hydraulic breaking hammer is relevant.
Background technology
Hydraulic breaking hammer, is called again " hydraulic burster " or " hydraulic rock breaker ", and its power resources are excavator or dress
The pressure oil that the pumping plant of carrier aircraft provides, can more effective fractured rock and armored concrete, excavator repacking in engineering construction
Hydraulic breaking hammer there is the advantages such as flexible, accurate, efficient, be widely used in mining, railway, highway, municipal administration gardens,
In the engineerings such as building construction.
The most existing hydraulic breaking hammer is directly to be replaced by the scraper bowl of excavator and make, and does not change excavator
Other versions.The hydraulic breaking hammer of this structure can give full play to its broken work when abandoned job space
With, but at restricted clearance, as in tunnel during operation, affected by excavator swing arm and dipper combining form, i.e. swing arm and dipper
There is certain angle not stretch completely, then can only crush and be positioned at excavator " lower section " and the rock of " front lower place " scope, and break
Broken scope is gradually reduced, and ultimately forms infundibulate, it is impossible to reaches continuous horizontal forward and crushes the effect of excavation.How to change
Enter so that in the range of hydraulic breaking hammer can be crushed to be positioned at excavator " dead ahead " even " front upper place " in restricted clearance
Rock, is the key issue of this utility model solution.
Utility model content
The excavator repacking hydraulic breaking hammer that this utility model is worked continuously forward in providing a kind of restricted clearance, in solution
State the deficiencies in the prior art, the problem solving to be unable to reach continuous horizontal operation forward when tunnel operation so that hydraulic crushing
Hammer can be crushed to be positioned at the rock in the range of excavator " dead ahead " even " front upper place " in restricted clearance.
In order to realize the purpose of this utility model, plan employing techniques below:
The excavator repacking hydraulic breaking hammer worked continuously forward in a kind of restricted clearance, it is characterised in that include arranging
Swing arm on excavator body, and bucket arm cylinder and hydraulic pressure hammer body, described bucket arm cylinder lower end is fixed on swing arm, upper end
Being simultaneously connected with rocking bar and connecting rod by link connector pin axle, described swing arm upper end connects hydraulic hammer by connecting bearing pin under scraper bowl
Body, swing arm upper end is additionally provided with swing arm rocking bar hinge hole, and the described rocking bar other end connects bearing pin through new by dipper rocking bar
Increasing hinge hole and be connected on swing arm, the described connecting rod other end connects hydraulic pressure hammer body by connecting bearing pin on scraper bowl.Described hydraulic pressure
The oil circuit of hammer body is connected by the bucket arm cylinder hydraulic tube arranged along swing arm upper limb.
The beneficial effects of the utility model are: only need to remove the dipper of excavator, scraper bowl and adnexa thereof, by straight for hydraulic pressure hammer body
Connect and be connected with excavator swing arm, i.e. complete hydraulic breaking hammer repacking, simple in construction, easy to implement, by excavator former dipper oil
The extension and contraction control quartering hammer of cylinder is faced upward or lower sleeping angle, even this structure is in restricted clearance, in tunnel, it is also possible to broken
Broken to the rock being positioned in the range of excavator " dead ahead " even " front upper place ", solve prior art and can only crush and be positioned at excavation
Machine " lower section " and the rock of " front lower place " scope, and the diminishing problem of broken scope so that hydraulic breaking hammer can be subject to
Continuous horizontal operation forward in limit space.
Accompanying drawing explanation
Fig. 1 shows the basic block diagram of excavator.
Fig. 2 shows repacking hydraulic breaking hammer structure chart of the present utility model.
Detailed description of the invention
As it is shown in figure 1, common scraper excavator includes the swing arm 1 being arranged on body, and dipper 2, bucket arm cylinder
4, scraper bowl 11 and bucket cylinder 12, swing arm 1 and dipper 2 connect bearing pin 3 by swing arm dipper and are attached, bucket arm cylinder 4 lower end
Being fixed on swing arm 1, upper end connects bearing pin 5 by bucket arm cylinder 4 and connects dipper 2, and scraper bowl 11 is by connecting bearing pin 14 under scraper bowl
Being connected to dipper 2 front end, bucket cylinder 12 lower end is fixed on dipper 2, and upper end is simultaneously connected with rocking bar by link connector pin axle 9
7 and connecting rod 8, connecting rod 8 connects scraper bowl 11 by connecting bearing pin 13 on scraper bowl, and rocking bar 7 connects bearing pin 10 by dipper rocking bar and connects
At dipper 2 front end, the bucket arm cylinder hydraulic tube 6 arranged along swing arm 1 upper limb is by the oil communication of bucket cylinder 12.
This utility model is to reequip in above-mentioned existing ordinary excavator basic structure, concrete as in figure 2 it is shown, remove
Swing arm dipper connects bearing pin 3, bucket arm cylinder connects bearing pin 5, and extracts bucket arm cylinder hydraulic tube 6, by dipper 2, scraper bowl 11, scraper bowl
Oil cylinder 12 separates with excavator body.Increase a swing arm rocking bar hinge hole 15 newly at swing arm 1 upper end oxygen-acetylene welding gun, use
Dipper rocking bar is installed on swing arm 1 and the connection of rocking bar 7, the aperture of swing arm rocking bar hinge hole 15 and relative position, with former dipper 2
The hinge hole aperture connecting bearing pin 10 is identical with relative position, to ensure that hydraulic pressure hammer body 16 can be directly connected on swing arm 1.Will
The other end of connecting rod 8 is connected on hydraulic pressure hammer body 16 by connecting bearing pin 13 on scraper bowl, is connected by under scraper bowl by swing arm 1 upper end
Pin axle 14 connects hydraulic pressure hammer body 16, and rocking bar 7 other end is connected bearing pin 10 through newly-increased hinge hole 15 by dipper rocking bar
It is connected on swing arm 1, then the oil circuit of hydraulic pressure hammer body 16 is connected recovery by bucket arm cylinder hydraulic tube 6, complete repacking.
This utility model solves the problem being unable to reach continuous horizontal operation forward when tunnel operation so that hydraulic pressure breaks
Broken hammer can be crushed to be positioned at the rock in the range of excavator " dead ahead " even " front upper place " in restricted clearance.
