Abstract

The invention discloses an excavator counter weight. The excavator counter weight comprises a shell, a clamshell-type cover and a counter weight body arranged inside the shell. The bottom face of the shell is provided with a locating groove and the counter weight body is located in the locating groove. The excavator counter weight is characterized in that a handle is arranged at the top of the counter weight body. By arranging the handle at the top of the counter weight body, when the clamshell-type cover of the shell is opened for replacing the counter weight body, the counter weight body can be moved by simply holding the handle, so that time and labor are saved and the problem that counter weight body replacement is difficult is solved.

Description

A kind of counter weight of excavator

Technical field

The present invention relates to excavator part field, be specifically related to a kind of counter weight of excavator.

Background technology

Excavator is widely used at present, is a kind of important engineering machinery.In order to keep balance, on excavator, need to install counterweight.Conventionally counterweight is fixed on excavator crossbeam.The topmost problem existing is at present that counter weight of excavator is changed difficulty.

Summary of the invention

Object of the present invention is to overcome deficiency of the prior art exactly, and a kind of counter weight of excavator is provided, and changes difficult problem thereby solve counter weight of excavator.

To achieve these goals, the technical solution used in the present invention is:

A kind of counter weight of excavator, comprises shell, renovates and is arranged at the balancing weight in shell, and there is locating slot described shell bottom surface, and described balancing weight is positioned at locating slot, it is characterized in that: the top of described balancing weight is provided with handle.

Further, described handle is positioned at the centre of balancing weight.

Further, the bottom surface of described locating slot is provided with as groove, on the bottom surface of balancing weight, is provided with projection, and described projection matches with described groove.

The invention has the advantages that: the top at described balancing weight is provided with handle, thereby when housing is renovated and opened, while changing balancing weight, just balancing weight can be moved by holding handle, time saving and energy saving, solve counterweight and changed difficult problem.Handle is arranged to the centre of balancing weight, prevents from affecting the whole machine balancing of counterweight.The bottom surface of described locating slot is made as to groove, on the bottom surface of balancing weight, is provided with projection, described projection matches with described groove, thereby better balancing weight is positioned, and prevents counterweight position skew in the time of work.Simultaneously by projection being set on the bottom surface of balancing weight, on the whole by the center of gravity of balancing weight down, further counterweight.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is longitudinal section of the present invention;

Mark in above-mentioned figure is:

1, shell, 2, renovate, 3, balancing weight, 4, locating slot, 5, handle, 6, groove, 7, projection.

The specific embodiment

Below in conjunction with Figure of description, the present invention is further illustrated.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.

As shown in Figures 1 and 2, shown in a kind of counter weight of excavator, comprise shell 1, renovate 2 and be arranged at the balancing weight 3 in shell, there is locating slot 4 described shell bottom surface, described balancing weight 3 is positioned at locating slot 4, the top of described balancing weight 3 is provided with handle 5.Be provided with handle 5 at the top of described balancing weight 3, thereby open when housing is renovated to 2, while changing balancing weight 3, just balancing weight 3 can be moved by holding handle 5, time saving and energy saving.Solve counterweight and changed difficult problem.

Further, described handle 5 is positioned at the centre of balancing weight 3.Handle 5 is arranged to the centre of balancing weight 3, prevents from affecting the whole machine balancing of counterweight.

Further, the bottom surface of described locating slot 4 is provided with groove 6, on the bottom surface of balancing weight 3, be provided with projection 7, described projection 7 matches with described groove 6, thereby better balancing weight 3 is positioned, prevent counterweight position skew in the time of work, simultaneously by projection 7 is set on the bottom surface at balancing weight 3, on the whole by the center of gravity of balancing weight 3 down, further counterweight.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
