Description
Technical field
The present invention relates to a kind of hinge, relate in particular to a kind of hinge for large excavator side door.
Background technology
At present, on market, the side door hinge of large hydraulic excavator is all continued to use the hinge of middle-size and small-size hydraulic crawler excavator, and hinge mostly is slabbed construction, and stressed little, anti-fatigue ability is poor.Because the operating mode of large hydraulic excavator is complicated, execution conditions are severe, and complete machine is hit, vibration force is larger, often cause the earlier period damage of hinge, change frequently hinge and not only bring the loss on economy, manpower, more may cause accident, jeopardize field personnel's personal safety.
Summary of the invention
For fear of the earlier period damage of side door hinge, the present invention proposes a kind of hinge for large excavator side door, and concrete technical scheme is:
Comprise portable plate, fixed head and bearing pin, fixed head and portable plate comprise respectively and are roughly rectangular base plate, portable plate can rotate relative to fixed head around bearing pin, it is characterized in that: the base plate two ends of described fixed head are respectively arranged with lateral wall, lateral wall protrudes from the base plate plane of fixed head, the base plate two ends of described portable plate are respectively arranged with middle sidewall, middle sidewall protrudes from the base plate plane of portable plate, the middle part of described fixed head has and is roughly rectangular hole, the two ends of hole are respectively arranged with inside wall, inside wall protrudes from the base plate plane of fixed head, lateral wall, on middle sidewall and inside wall, be respectively arranged with connecting hole, bearing pin is connected and fixed plate and portable plate by connecting hole, the lateral wall at fixed head two ends connects by the first connection sidewall, and the middle sidewall at portable plate two ends connects by the second connection sidewall, and the inside wall at hole two ends, fixed head middle part connects sidewall by the 3rd and connects, when the bottom surface of fixed head and portable plate is during in parallel position, the height of described middle sidewall is higher than the height of inside wall and lateral wall.
Described bearing pin is the middle crooked bearing pin with sweep.
Described hole is positioned at the side that the middle part of fixed head relative first connects sidewall, the base plate of fixed head is " recessed " font.
The invention has the advantages that:
By the profiled sheeting group that is designed to special shape, to being assembled, intensity is high, anti-vibration, thus guaranteed the quality of product and improved the reliability of hydraulic crawler excavator work.
Accompanying drawing explanation
Accompanying drawing 1 is existing design of part schematic diagram;
The A-A that accompanying drawing 2 is existing part is to sectional view;
The front view that accompanying drawing 3 is a preferred embodiment of the invention;
The lateral view that accompanying drawing 4 is a preferred embodiment of the invention;
Accompanying drawing 5 is the front view of another preferred embodiment of the present invention.
Reference numeral is as follows:
1-fixed head; 2-portable plate; 3-lateral wall; Sidewall in 4-; 5-inside wall; 6-first connects sidewall; 7-second connects sidewall; 8-the 3rd connects sidewall; 9-bearing pin; The crooked bearing pin of 10-.
The specific embodiment
Below in conjunction with the preferred embodiment described in accompanying drawing 3-4, hinge of the present invention is made to further detailed description.It comprises portable plate, fixed head and bearing pin, fixed head and portable plate comprise respectively and are roughly rectangular base plate, the material of base plate can adopt 45# steel, portable plate can rotate relative to fixed head around bearing pin, base plate two minor faces at fixed head arrange respectively lateral wall, lateral wall protrudes from the base plate plane of fixed head, height can meet the needs that bearing pin is firmly installed, base plate two minor faces of described portable plate arrange respectively middle sidewall, middle sidewall protrudes from the base plate plane of portable plate, and when the bottom surface of fixed head and portable plate is during in parallel position, the height of middle sidewall will be higher than the height of lateral wall, to facilitate the installation of hinge, thereby to make hinge portable plate when folding in can not being absorbed in fixed head completely, reduce by two plates overlapping to depositing the unnecessary trouble of bringing simultaneously, the middle part of fixed head has and is roughly rectangular hole, preferably hole is positioned at fixed head one side, the base plate of fixed head is " recessed " font, the two ends of hole are respectively arranged with inside wall, inside wall protrudes from the base plate plane of fixed head, the setting of hole and inside wall has reduced the use of material, can play reinforcement effect to bearing pin again, can also play the guiding role to the installation of bearing pin simultaneously, lateral wall, on middle sidewall and inside wall, be respectively arranged with connecting hole, bearing pin is connected and fixed plate and portable plate by connecting hole, the lateral wall at fixed head two ends connects sidewall by one first and connects, the middle sidewall at portable plate two ends connects sidewall by one second and connects, the inside wall at hole two ends, fixed head middle part connects sidewall by one the 3rd and connects, preferred first and second connect on the edge of opposite side that sidewalls arrange two base plates, first connects sidewall and is arranged on the bottom edge that does not have a pertusate side in other words on hinge outermost fixed head edge, second connects sidewall is arranged on the outermost portable plate of hinge edge, the 3rd to connect sidewall relative with the second connection sidewall and be connected sidewall with the 3rd and be positioned at the same side, with this, make fixed head and portable plate form box type substantially, strengthen the structural strength of hinge, the mode connecting can adopt welding, also can adopt other suitable connected mode.
Accompanying drawing 5 has been described another preferred embodiment of the present invention, the difference of itself and above preferred embodiment is that its bearing pin is crooked bearing pin, the supporting capacity of the bearing pin that crooked bearing pin not only strengthens, increased the elastic deformation ability of hinge in the vertical direction, can also effectively reduce the space that hinge occupies when closed, more be conducive to structure design and the layout of excavator side door.Sweep in crooked bearing pin can be that after installing, to use mechanical means to cause curved, can be also directly to use crooked bearing pin, because its mounting method is the common practise of this area, therefore at this, will not tire out and state.
The above; it is only the preferably specific embodiment of patent of the present invention; but the protection domain of patent of the present invention is not limited to this; anyly be familiar with in technical scope that those skilled in the art disclose in patent of the present invention; the variation that can expect easily or replacement, within all should being encompassed in the protection domain of patent of the present invention.
