Description
Technical field
The present invention relates to a kind of hinge, relate in particular to a kind of hinge that is used for the large excavator side door.
Background technology
At present, the side door hinge of large hydraulic excavator is all continued to use the hinge of middle-size and small-size hydraulic crawler excavator on the market, and mostly hinge is slabbed construction, and stressed little, anti-fatigue ability is poor.Because of the operating mode of large hydraulic excavator is complicated, execution conditions are abominable, and complete machine is hit, vibration force is bigger; Often cause the early stage damage of hinge; Frequent replacing hinge not only brings the loss on economy, the manpower, more possibly cause accident, jeopardizes field personnel's personal safety.
Summary of the invention
For fear of the early stage damage of side door hinge, the present invention proposes a kind of hinge that is used for the 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 be roughly rectangular base plate, and portable plate can be around the rotation of bearing pin relative fixed plate, and it is characterized in that: the base plate two ends of said 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 said portable plate are respectively arranged with middle sidewall, and middle sidewall protrudes from the base plate plane of portable plate, and the middle part of said 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, is respectively arranged with connecting hole on lateral wall, middle sidewall and the inside wall, and bearing pin connects fixed head and portable plate through connecting hole; The lateral wall at fixed head two ends connects sidewall through first and connects, and the middle sidewall at portable plate two ends connects sidewall through second and connects, and the inside wall at hole two ends, fixed head middle part connects sidewall through the 3rd and connects; When fixed head was in parallel position with the bottom surface of portable plate, the height of said middle sidewall was higher than the height of inside wall and lateral wall.
Said bearing pin is that the centre has the curved portions bearing pin.
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:
To being assembled, intensity is high by the profiled sheeting group that is designed to special shape, anti-vibration, thus guarantee the quality of product and improved the reliability of hydraulic crawler excavator work.
Description of drawings
Accompanying drawing 1 is existing design of part sketch map;
Accompanying drawing 2 is to have the A-A of part now to sectional view;
Accompanying drawing 3 is the front view of a preferred embodiment of the invention;
Accompanying drawing 4 is the lateral view of a preferred embodiment of the invention;
Accompanying drawing 5 is the front view of another preferred implementation of the present invention.
Reference numeral is following:
The 1-fixed head; The 2-portable plate; The 3-lateral wall; Sidewall among the 4-; The 5-inside wall; 6-first connects sidewall; 7-second connects sidewall; 8-the 3rd connects sidewall; The 9-bearing pin; The crooked bearing pin of 10-.
The specific embodiment
Preferred embodiment below in conjunction with described in the accompanying drawing 3-4 is made further detailed description to hinge of the present invention.It comprises portable plate, fixed head and bearing pin, and fixed head and portable plate comprise respectively and be roughly rectangular base plate that the material of base plate can adopt the 45# steel; Portable plate can be around bearing pin relative fixed plate rotation, at base plate two minor faces of fixed head lateral wall is set respectively, and lateral wall protrudes from the base plate plane of fixed head; Height can satisfy the needs that bearing pin firmly is installed and get final product, and base plate two minor faces of said portable plate are provided with middle sidewall respectively, and middle sidewall protrudes from the base plate plane of portable plate; And when fixed head was in parallel position with the bottom surface of portable plate, the height of middle sidewall will be higher than the height of lateral wall, to make things convenient for the installation of hinge; Thereby hinge portable plate when folding can be absorbed in fully reduce in the fixed head overlapping the giving of two plates to deposit the unnecessary trouble of bringing, the middle part of fixed head has and is roughly rectangular hole, and preferred 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, and inside wall protrudes from the base plate plane of fixed head, and the setting of hole and inside wall has promptly reduced the use of material; Can play reinforcement effect to bearing pin again; Can also the installation of bearing pin be play the guiding role simultaneously, be respectively arranged with connecting hole on lateral wall, middle sidewall and the inside wall, bearing pin connects fixed head and portable plate through connecting hole; The lateral wall at fixed head two ends connects sidewall through one first and connects; The middle sidewall at portable plate two ends connects sidewall through one second and connects; The inside wall at hole two ends, fixed head middle part connects sidewall through one the 3rd and connects, and preferred first and second connect on the edge of opposite side that sidewalls are provided with two base plates, and promptly first connects on the bottom edge that sidewall is arranged on a side that does not have hole in other words on the hinge outermost fixed head edge; Second connects sidewall is arranged on the outermost portable plate of the hinge edge; The 3rd connection sidewall is connected sidewall, and being connected sidewall with the 3rd is positioned at the same side relatively with second, makes fixed head and portable plate constitute box type substantially with this, strengthens the structural strength of hinge; Ways of 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-mentioned 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; Increase the elastic deformation ability of hinge in the vertical direction, can also effectively reduce the space that hinge occupies when closed, more helped the structure design and the layout of excavator side door.Sweep in the crooked bearing pin can be the back to be installed to use mechanical to cause curved, also can be directly to use crooked bearing pin, because its mounting method is the common practise of this area, therefore will not tires out at this and state.
The above; Be merely the preferable specific embodiment of patent of the present invention; But the protection domain of patent of the present invention is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that patent of the present invention discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of patent of the present invention.
