Description
Technical field
The present invention relates to loader field, particularly a kind of electronic controllable loading machine of multi link.
Background technology
Engineering machinery is the general name of the construction machinery for engineering construction, and loader is one of topmost engineering machinery.Loader is widely used in the restoration in earth-rock construction machinery of the construction projects such as highway, railway, building, mine, is mainly used in the shovel dress material such as soil, sandstone, it is possible to Ore, pan soil etc. are made slight shovel and pretends industry.Loader hydraulic formula and mechanical type two kinds, fluid pressure type loader, because of advantages such as mobility are good, flexible, is widely used in various field, but fluid pressure type loader also has many deficiencies and shortcoming, first, Hydraulic Elements requirement on machining accuracy is high, manufactures comparatively difficulty, has raised the cost of whole loader, secondly, Hydraulic Elements are in use maintained and are required that technology is higher, and difficulty is relatively big, and maintenance cost is high；Further, hydraulic oil temperature influence is big, aggregate efficiency is low, sometimes has noise and vibration.Previous mechanical type loader is simple due to action, bearing capacity is big, it is mainly used in the places such as mine, the electric loading mechanism occurred later has changed link transmission into hydraulic system, by driven by servomotor, although solving the leakage of oil that Hydraulic Elements easily occur, the shortcomings such as maintenance cost is high, but, current controllable loading mechanism has simply changed connecting rod into hydraulic pressure, other structure is not made any change, it does not have consider the reasonability of replacement, constrain the practicality of mechanical type controllable loading mechanism.
In traditional electric loading mechanism, the middle part of rocking arm and swing arm connect, and two ends are connected with pull bar and rotary ink tank respectively, and when rotary ink tank is flexible, rocking arm rotates around its middle strong point, made on scraper bowl turn by pull bar or under turn over.Existing mechanical type controllable loading mechanism has simply replaced to linkage rotary ink tank, and Rocker arm section is not changed accordingly; rocking arm still by around intermediate supports point rotate come pushing drawing rod make on scraper bowl turn or under turn over; in this case; when scraper bowl is in limit position shape; pull bar, rocking arm and first connecting rod easily produce Singularity, reduce the reliability of electric loader.
Summary of the invention
It is an object of the invention to provide a kind of multi link elevating conveyor, meet loader job requirements, and there is the advantages such as hydraulic loader bearing capacity is big, stress is good, overcome the shortcomings such as conventional hydraulic excavator maintenance cost is high, reaction is sensitive not, when also avoiding scraper bowl approaching or at limit position shape simultaneously, easily produce the shortcomings such as Singularity, improve bearing capacity and the reliability of electric loading mechanism.
To achieve these goals, present invention employs techniques below scheme:
A kind of electronic controllable loading machine of multi link, including car body, scraper bowl, connecting rod one, connecting rod two, connecting rod three, connecting rod four, connecting rod five, connecting rod six, connecting rod seven, connecting rod eight, connecting rod nine, connecting rod ten and connecting rod 11,
Described connecting rod one one end is connected on car body by revolute pair one, connecting rod one other end is connected on scraper bowl by revolute pair two, connecting rod two one end revolute pair three is connected on car body, connecting rod two other end is connected with connecting rod three one end by revolute pair four, connecting rod three other end is connected on connecting rod one by revolute pair five
Described connecting rod four one end is connected on car body by revolute pair six, connecting rod four other end is connected on scraper bowl by revolute pair seven, connecting rod five one end revolute pair eight is connected on car body, connecting rod five other end is connected with connecting rod six one end by revolute pair nine, connecting rod six other end is connected on connecting rod two by revolute pair ten
The described connecting rod end July 1st is connected on car body by revolute pair 11, connecting rod seven other end is connected with connecting rod Aug. 1st end by revolute pair 12, connecting rod eight other end is connected with connecting rod nine one end by revolute pair 13, and connecting rod nine other end is connected on scraper bowl by revolute pair 14
Described connecting rod 11 one end is fixed on connecting rod one, and connecting rod 11 other end is fixed on connecting rod two, and connecting rod ten one end is connected on connecting rod eight by revolute pair 15, and connecting rod ten other end is connected on connecting rod 11 by revolute pair 16.
Compared with prior art, the beneficial effect that the present invention possesses:
1, under the premise ensureing carriage requirement, the present invention can keep away easily electric loader because of scraper bowl close to or up extreme position time drive line angle is excessive or the too small unusual appearance even produced, thus effectively prevent the impact to frame for movement or the destruction that loading shovel switching mechanism causes because of Singularity, improve the reliability of electric loader, not only increase the practicality of this bucket turnover mechanism, it is thus also avoided that the locking phenomenon therefore produced.
2, this invention simplifies electric loading mechanism, not only make each rod member stress more reasonable, improve the bearing capacity of loader switching mechanism, and improve the dynamic performance of electric loading mechanism, improve the rigidity of whole loader mechanism, so as to be more suitable for manufacturing large-duty loader, under same power of motor and other relevant parameter, the motor using smaller power just can make scraper bowl produce bigger turning torque, and then has obvious energy-saving effect.
3, the present invention adopts linkage to substitute Hydraulic Power Transmission System, the every work energy requirement of hydraulic loader can not only be reached, also there is movement response rapid, the sensitive advantage such as efficiently, and overcome that conventional hydraulic excavator maintenance cost is high, the hydraulic circuit easily shortcoming such as affected by environment, and simpler with other electric loading mechanism structure compared efficiently.
