Abstract
The utility model relates to an automatic leveling pull rod mechanism for small-size loading machine, the tipping bucket hydro-cylinder keeps under the motionless condition of certain state, through the state that changes the lift hydro-cylinder, thereby realize that the work arm is circular motion around the B point, do circular motion around the B point simultaneously with work arm articulated J point and E point, when the E takes place the motion a little, because the tipping bucket hydro-cylinder keeps motionless at certain state (being the distance between C point and the F point unchangeable), the linkage takes place a little at H under the effect of rocking arm and pull rod. The included angle alpha between the connecting line between the J point and the H point and the horizontal plane is ensured to float only in a small range, and finally, the leveling effect is realized in the process of loading and unloading goods.
Description
Technical Field
The utility model relates to an engineering machine tool technical field, in particular to an automatic leveling pull rod mechanism for small-size loading machine.
Background
The existing small-sized engineering machinery needs to operate leveling by double handles simultaneously during working, has complex operation, high requirement on proficiency, poor leveling effect, easy cargo tipping during loading and unloading, great difficulty in operation for a driver and easy occurrence of safety accidents.
The utility model discloses how research makes engineering machine realize the leveling effect loading, uninstallation goods in-process.
Disclosure of Invention
In order to solve the technical problem, the utility model relates to an automatic leveling pull rod mechanism for small-size loading machine, its technical scheme is:
the lifting device comprises a vehicle body, a lifting oil cylinder, a working arm, a tipping bucket oil cylinder, a rocker arm, a pull rod and a hanging frame, wherein one end of the lifting oil cylinder, one end of the working arm and one end of the tipping bucket oil cylinder are respectively hinged with the vehicle body; the other end of the lifting oil cylinder is hinged with the middle part of the working arm;
the tail part of the working arm is hinged with one end of the hanging rack;
the middle lower part of the working arm is hinged with one end of the rocker arm;
the other end of the rocker arm is provided with two hinged joints, and the tipping bucket oil cylinder and one end of the pull rod are respectively hinged with the hinged joints of the rocker arm; the other end of the pull rod is hinged with the hanging rack.
Further, when the tipping bucket oil cylinder is kept still, the lifting oil cylinder is driven, the working arm does circular motion along a hinge point B point of the vehicle body, and meanwhile, the rocker arm hinged with the working arm and the hinge point of the hanging rack do circular motion around the hinge point B point.
Furthermore, a connecting line of two hinge points of the hanging rack is used as a y-axis, and an included angle between the y-axis and the horizontal plane is alpha.
The utility model has the advantages that: the utility model relates to an automatic leveling pull rod mechanism for small-size loading machine, the tipping bucket hydro-cylinder keeps under the motionless condition of certain state, through the state that changes the lift hydro-cylinder, thereby realize that the work arm is circular motion around the B point, do circular motion around the B point simultaneously with work arm articulated J point and E point, when the E takes place the motion a little, because the tipping bucket hydro-cylinder keeps motionless at certain state (being the distance between C point and the F point unchangeable), the linkage takes place a little at H under the effect of rocking arm and pull rod. The included angle alpha between the connecting line between the J point and the H point and the horizontal plane is ensured to float only in a small range, and finally, the leveling effect is realized in the process of loading and unloading goods.
Drawings
FIG. 1 is a schematic structural view of the present invention with a lifting position I;
FIG. 2 is a schematic structural view of the utility model with a lifting position II;
as shown in the figure, 1 vehicle body, 2 lifting oil cylinders, 3 working arms, 4 tipping oil cylinders, 5 rocker arms, 6 pull rods and 7 hanging racks;
A. b, C, D, E, F, G, H, J are all connection points (or hinge points);
alpha is the included angle between the connecting line of the two points H and J and the horizontal plane.
Detailed Description
As shown in the figure, the utility model relates to an automatic leveling pull rod mechanism for small-size loading machine, including automobile body 1, lift cylinder 2, work arm 3, tipping bucket hydro-cylinder 4, rocking arm 5, pull rod 6 and stores pylon 7. The lifting oil cylinder, the working arm and the tipping bucket oil cylinder are respectively movably connected (or hinged) with the vehicle body through a point A, a point B and a point C. The points A, B and C are all fixed points on the vehicle body. The lifting oil cylinder, the rocker arm and the hanging frame are respectively and movably connected with the working arm through a D point, an E point and a J point. The tipping bucket oil cylinder and the pull rod are respectively movably connected with the rocker arm through an F point and a G point. The pull rod is movably connected with the hanging rack through an H point.
The utility model discloses a working process:
under the condition that the tipping bucket oil cylinder keeps a certain state and is still (namely, the distance between the point C and the point F is ensured to be unchanged), the distance between the point A and the point D of the lifting oil cylinder is changed, so that the working arm circularly moves around the point B, namely, the point J and the point E circularly move around the point B at the same time. Meanwhile, when the point E does circular motion, the distance between the point C and the point F is unchanged, and the linkage of the point H is realized through the action of the rocker arm and the pull rod. Namely, when the working arm does circular motion through the lifting oil cylinder, the J point and the H point are regularly linked at the same time, so that the included angle between the connecting line between the J point and the H point and the horizontal plane is ensured to float only within a small amplitude range, and a certain leveling effect is realized. The utility model discloses simple structure, easily assembly realizes certain leveling effect at loading, uninstallation goods in-process automation. As shown in fig. 1 and 2, the angle α changes only to a small extent in both lifting states.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
