Background technology
At home, the heavy coal-winning machine of 6.3m mining height still belongs to the starting stage, and coal-winning machine before this all is the underneath type adjust high cylinder, and promptly adjust high cylinder is arranged on the position of fuselage below rib side coal outlet, and above-mentioned underneath type adjust high cylinder extensively adopts in medium and small type.But in especially big type, the underlying oil cylinder will reach same mining height, just must improve the fuselage height of coal-winning machine, the fuselage height is wanted corresponding increasing more than the 400mm, this just makes on the center of gravity of coal-winning machine complete machine and moves, and this just influences the job stability of coal-winning machine, and has increased the danger that fuselage is toppled over.
Simultaneously, the coal-winning machine of adjust high cylinder underlying also exists following defective and deficiency in actual use: 1, adopt the coal-winning machine of underneath type adjust high cylinder to increase with fuselage, the idle pulley transmission of corresponding increase one-level walking case, this just makes the walking box structure complexity of coal-winning machine, and dress, tear open and safeguard all extremely inconveniently, and increased the trouble point.2, the adjust high cylinder of underneath type is sitting at the position of rib side coal outlet, has so not only reduced the space of coalingging, and it is broken repeatedly that coal is squeezed in cylinder, reduced the coal cinder rate.Because the extruding of coal often is damaged the oil pipe of oil cylinder and joint, also increased fault rate simultaneously.To sum up, traditional underneath type adjust high cylinder obviously is not suitable for using on the heavy coal-winning machine of super high seam.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, the heavy coal-winning machine of putting on a kind of adjust high cylinder is provided, it is reasonable in design, mining height is big, power is big, from great and fuselage is low, the complete machine good operating stability can solve effectively that existing mining height is little in the existing heavy coal-winning machine use, deadweight is little, fuselage is high, practical problem such as more than complete machine poor work stability and the trouble point.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the heavy coal-winning machine of putting on a kind of adjust high cylinder comprises removable fuselage, is installed in tractive unit in the fuselage, is installed in the left cutting units and the right cutting units of the fuselage left and right sides respectively, the left lateral that is installed in the left and right sides, fuselage below is walked mechanism and right lateral is walked mechanism and be installed in hydraulic gear and electrical control system in the fuselage; Described electrical control system comprises the frequency converter case, high-voltage switch gear case, pump box, the transformer tank that are laid on the fuselage front side wall, left lateral walks case and right lateral is walked case; Described left cutting units comprises the left rocking arm that is hinged on the fuselage, the left cutting motor that rolls left tube and the tube that rolls left is driven that is installed in left rocking arm front end, and described right cutting units comprises the right rocking arm that is hinged on the fuselage, the right cylinder that is installed in right rocking arm front end and the right cutting motor that right cylinder is driven; Tractive unit comprises left haulage gear and the right haulage gear that is installed in the left and right sides in the fuselage, left side haulage gear comprises left traction electric machine and passes through described hydraulic gear to left rocking arm, left lateral is walked the left driving pump group that mechanism and left adjust high cylinder drive, right haulage gear comprise right traction electric machine and by hydraulic gear to right rocking arm, right lateral is walked the right driving pump group that mechanism and right adjust high cylinder drive, described left driving pump group and right driving pump group are driven by left traction electric machine and right traction electric machine respectively, and described left adjust high cylinder and right adjust high cylinder are adjusted mining height and planted agent's amount of left cutting units and right cutting units by hydraulic gear respectively; Be equipped with on the described fuselage piece of coalingging in roll left tube and the right cylinder is carried out broken crushing mechanism and the broken oil cylinder that crushing mechanism is driven, it is characterized in that: described left adjust high cylinder and right adjust high cylinder are installed in the back left and right sides respectively, left side rocking arm and right rocking arm are hinged on two sidewall upper portions about fuselage respectively, two corresponding respectively being provided with for left rocking arm and the hinged hinge hole of right rocking arm of sidewall upper portion about described fuselage.
Be provided with the whole oblique backplate of tilt adjustable directly over the described fuselage.
The angle of inclination of described oblique backplate is adjusted by the oblique backplate oil cylinder that is arranged on the fuselage.
The end, the left and right sides of described back is provided with respectively left link and the right link that is connected with right rocking arm with left rocking arm.
Described left adjust high cylinder and right adjust high cylinder are installed in back by left oil cylinder seat and right oil cylinder seat respectively.
The utility model compared with prior art has the following advantages:
1, reasonable in design, mining height is big, power is big, from great and fuselage is low, the complete machine good operating stability.
2, with about two adjust high cylinders be laid in the left and right sides of back, be about to the position that tradition is laid in two adjust high cylinders of fuselage below and be adjusted to back; Simultaneously with about the articulated position of two rocking arms also be changed to back, be about to postpone on the adjust high cylinder, also the centre of gyration of rocking arm is increased, thereby has been increased the pivot angle of rocking arm, increased mining height, mining height of the present utility model can reach six meters.
3, above two oil cylinders of last postpone, add the whole oblique backplate of tilt adjustable, to guarantee the other operating personnel's of back spare and pipeline and machine safety.Move to the home under the oblique backplate in the postpone on the adjust high cylinder, corresponding oil pipe and joint also, thereby reduced the fault rate of oil cylinder work.
Though 4, postpone has local crowning on the adjust high cylinder, the plane remains within 2.2 meters on the whole fuselage, and the coal-winning machine fuselage height of its height and existing 4-5 rice mining height is close; And complete machine weight has increased more than one times, and mining height increases more than one meter; In addition since machine gravity reduce, thereby improved the job stability of machine greatly, and strengthened the scope of heightening, realized the new breakthrough of six meters of mining heights.
5, with postpone on the adjust high cylinder, near the coal port the cylinder smooth along, strengthened the lumpiness of producing coal, and reduced coal and squeeze power consumption broken repeatedly in rib.
In sum, the utility model is reasonable in design, mining height is big, power is big, from great and fuselage is low, the complete machine good operating stability can solve effectively that existing mining height is little in the existing heavy coal-winning machine use, deadweight is little, fuselage is high, practical problem such as more than complete machine poor work stability and the trouble point.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
