The utility model discloses a realize that the technical scheme of its purpose is like: the filling counterweight comprises an iron shell, a framework, a lifting plate and an installation base, wherein the framework is positioned in the iron shell and welded with the iron shell, the bottom of the iron shell is positioned on the installation base welded with the iron shell, a filler is cast in the iron shell, the filling counterweight is characterized in that the lifting plate is arranged in the iron shell, the top of the lifting plate protrudes to the outside of the iron shell, the top of the lifting plate is provided with a lifting hole, and the lifting plate is welded with the framework in the iron shell and welded with the installation base at the bottom of the lifting plate. The utility model discloses in, lift by crane skeleton and the installation base welding in board lower part and the filling counter weight mutually, have sufficient intensity. Therefore, the balance weight is arranged on the excavator, and the lifting hole on the balance weight can be used as a lifting point of the whole excavator, so that the excavator can be lifted conveniently.

In the filling counterweight, the number of the lifting plates arranged in the iron shell is two, and the two lifting plates are in mirror symmetry with respect to the central plane of the counterweight. Furthermore, a cross beam is arranged between the two lifting plates, and two ends of the cross beam are respectively welded with the two lifting plates.

In the filling counterweight, the framework is welded on the back plate of the iron shell, and the rear side edge of the lifting plate is welded with the framework. Furthermore, the framework is formed by welding angle steels, and a notch for embedding a steel plate of the angle steel on the framework is formed in the rear side edge of the lifting plate.

In the above-mentioned filling counter weight, the installation base is including the level arrange and be used for setting up the mounting panel of installation screw hole, rise the hanger plate with the top surface vertical welding of mounting panel. Further, a reinforcing plate is welded between the mounting plate and the lifting plate.

The utility model discloses a realize that the technical scheme of its purpose is like: an excavator is constructed having the aforementioned filling weight.

Compared with the prior art, the utility model provides an be provided with the hanger plate on the excavator filling counter weight, it has sufficient intensity and is used for lifting by crane complete machine weight to make things convenient for the complete machine handling.

Part names and serial numbers in the figure:

the steel plate lifting device comprises a lifting plate 1, a cross beam 11, a reinforcing plate 12, an iron shell 2, a framework 3, a mounting base 4, a mounting plate 41 and a threaded pipe 42.

Detailed Description

The following description of the embodiments refers to the accompanying drawings.

As shown in fig. 1, the filling counterweight in this embodiment is an excavator counterweight, and is fixedly installed at the rear of an excavator platform. The filling counter weight includes iron-clad 2, be located the iron-clad and with iron-clad welded skeleton 3, be located iron-clad bottom and iron-clad welded installation base 4, cast the filler in the iron-clad, for example cement concrete etc..

As shown in fig. 2, a lifting plate 1 is arranged in an iron shell 2, the top end of the lifting plate 1 protrudes out of the iron shell from the top of the iron shell 2, a lifting hole is formed in the top of the lifting plate, the lifting plate 1 is welded with a framework 3 in the iron shell 2, and the bottom of the lifting plate 1 is welded with an installation base 4. The two lifting plates 1 arranged in the iron shell 2 are mirror-symmetrical about the center plane of the balance weight. A cross beam 11 is arranged between the two lifting plates 1, and two ends of the cross beam 11 are respectively welded with the two lifting plates 1. The beam 11 is used for preventing the hoisting plate from bending and deforming in the process of hoisting the balance weight, and simultaneously, the effect of reinforcing the hoisting plate and the cement concrete in the iron shell is also enhanced.

The framework 3 is welded on the back plate of the iron shell 2 to form a frame structure, so that the back plate is prevented from deforming. The rear side edge of the lifting plate 1 is welded with the framework 3, the framework 3 is formed by welding angle steel, a notch for embedding a steel plate of the angle steel on the framework is formed in the rear side edge of the lifting plate 1, and the connecting strength of the lifting plate 1 and the framework 3 is enhanced.
