The utility model aims to solve the technical problem that a counterweight block testing device for a large excavator bucket is provided, which can be tested in place once and improve the working efficiency.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
a heavy block testing device for a large excavator comprises a detection plate and movable supporting legs, wherein the detection plate is provided with a through hole corresponding to an installation hole in a balancing weight, the left front end and the right front end of the detection plate are provided with positioning surfaces aligned with the outer wall of the balancing weight, and the left outer side and the right outer side of the detection plate are provided with reference surfaces matched with the outermost side edges of the balancing weight; the movable support leg comprises a movable leg, the movable leg is hinged with the detection plate, the middle position of the movable leg is hinged with the first connecting rod, the other end of the first connecting rod is hinged with the second connecting rod, the second connecting rod is hinged with the detection plate, and when the movable leg is vertical, the movable leg, the first connecting rod and the second connecting rod form a right triangle.
The detection plate is provided with lightening holes.
The movable leg comprises an upper supporting leg and a lower supporting leg, and the upper supporting leg is in threaded connection with the lower supporting leg.
The detection plate is made of iron materials.
The utility model relates to a supporting pouring weight verifying attachment of large-scale bucket machine has following technological effect: through adopting dedicated pick-up plate, utilize locating surface, reference surface and balancing weight to align, utilize the through-hole to come the inspection mounting hole and process and reach the requirement, simple swift once targets in place. In addition, by arranging the movable supporting legs, the movable supporting legs can be directly moved horizontally during measurement, so that the labor intensity is reduced; can fold when not using, vertical placement saves space, reduces and is hit the risk of warping.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic structural view of a counterweight.
Fig. 2 is a schematic structural diagram of the present invention.
Fig. 3 is a schematic structural diagram of the present invention.
Fig. 4 is a front view of the present invention.
FIG. 5 is a schematic view of detection by the detection plate.
In the figure: the detection device comprises a detection plate 1, a movable supporting leg 2, a balancing weight 3, a mounting hole 4, a through hole 5, a positioning surface 6, a reference surface 7, a movable leg 8, a first connecting rod 9, a second connecting rod 10, a lightening hole 11, an upper supporting leg 8-1, a lower supporting leg 8-2 and a mounting base 12.
Detailed Description
As shown in figures 1-5, the device for testing the counterweight of the large-scale excavator comprises a detection plate 1 and a movable supporting leg 2. The detecting plate 1 is integrally matched with the shape of the inner ring of the balancing weight, three through holes 5 are formed in the front end of the detecting plate 1, and the through holes 5 are used for detecting whether the aperture and the relative position accuracy of the mounting holes 4 in the balancing weight 3 meet requirements or not. For accurate location, be equipped with the locating surface 6 that aligns with balancing weight 3 outer wall at the left and right front end of pick-up plate 1, be equipped with the reference surface 7 with balancing weight 3 outside edge assorted about the pick-up plate 1 outside. When detecting, align reference surface 7 of detection plate 1 with the edge about the balancing weight 3, laminate the terminal surface of balancing weight 3 with locating surface 6 of detection plate 1, can directly observe the relative position relation of through-hole 5 and mounting hole 4 after aligned, if through-hole 5 aligns and the size is unanimous with mounting hole 4 then the explanation is qualified, otherwise need to do over again.
Because the hoist needs to carry out the handling to balancing weight 3 or other spare parts. Therefore, in order to avoid the detection plate 1 from being damaged by negligence or deformation caused by other reasons such as cold and heat, the detection plate 1 is made of an iron material, has certain deformation resistance and is an existing material. For easy identification, colored paint may be painted on the outside of the detection plate 1.
In addition, the interval between the reference surface 7 of the detection plate 1 in the application is more than 2 meters, and when in detection, because the weight is heavy, the detection plate is inconvenient to carry, so the bottom end of the detection plate 1 is provided with the foldable movable supporting leg 2.
The number of the movable supporting legs 2 is 5, and the movable supporting legs are uniformly distributed according to the front two and the rear three. Each movable supporting leg 2 comprises a movable leg 8, universal wheels with brakes are mounted at the bottom ends of the movable legs 8, the top ends of the movable legs 8 are hinged to the detection plate 1, the middle positions of the movable legs 8 are hinged to the first connecting rod 9, the other end of the first connecting rod 9 is hinged to the second connecting rod 10, the second connecting rod 10 is hinged to the detection plate 1, and the first connecting rod 9 and the second connecting rod 10 are the same in length. When the moving leg 8 is vertical, the moving leg 8, the first link 9, and the second link 10 form a right triangle. When the detection plate is not used, force is applied inwards and vertically along a hinge point between the first connecting rod 9 and the second connecting rod 10, the first connecting rod 9 and the second connecting rod 10 are bent, the movable legs 8 are closed inwards, and finally the three are folded and attached to the lower end face of the detection plate 1.
The detection plate 1 is provided with a lightening hole 11. Thereby reducing the weight of the device.
The movable leg 8 comprises an upper leg 8-1 and a lower leg 8-2, and the upper leg 8-1 and the lower leg 8-2 are in threaded connection. Because the detecting plate 1 of the device needs to be attached to the upper surface of the mounting seat 12 of the balancing weight 3, the height of the detecting plate 1 can be adjusted by arranging the upper supporting leg 8-1 and the lower supporting leg 8-2 and adopting a threaded connection mode, and the phenomenon that the upper surfaces of the detecting plate 1 and the mounting seat 12 cannot be attached due to assembly errors or other errors is avoided. In order to adjust the uniform height of each moving leg 8, scales are marked on the screw part of the lower leg 8-2 by red paint and are adjusted according to the scales.
