Abstract

The invention belongs to the field of engineering machinery and particularly relates to a novel engineering machinery cement counterweight which comprises a cement counterweight main body and an iron skin outer layer which wraps the cement counterweight main body. The novel engineering machinery cement counterweight is characterized by also comprising an installation hole which is formed in the bottom of the counterweight and extends inwards, wherein the counterweight is fixed at the supporting part by the installation hole. According to the novel engineering machinery cement counterweight disclosed by the invention, the counterweight is stably connected with the supporting part of an excavator main body by inserting the same stud into the installation hole and a supporting hole; through the connection between a hoisting hole and a plug, when the counterweight is not hoisted, the hoisting hole is not corroded by rainwater, and in addition, the rainwater is ensured not to be accumulated near the hoisting hole by a salient; and when cement is poured to carry out counterbalancing, if the condition of inhomogeneity of pouring density occurs, a balancing weight is adopted to regulate counterbalancing, thus ensuring stable running of an excavator.

Description

New engineering machinery cement balance weight

Technical field

The invention belongs to engineering machinery field, be specifically related to a kind of New engineering machinery cement balance weight for counter weight of excavator.

 

Background technology

Counterweight is one of vitals of excavator, and the stability during to machine works plays an important role.Counterweight need to be in some way connected on the excavator base machine main body.In addition, counterweight is moved to the excavator base machine main body, then need lifting, lifting realizes by hole for hoist usually, when running into the ectocine such as rainwater, and the hole for hoist corrosion that gets rusty easily, the realization that impact lifts.In addition, to the counterweight casting cement time, as run into the inhomogenous situation of pouring density, then affect the stability of whole machine.

 

Summary of the invention

The object of the invention is to overcome the problems referred to above, a kind of New engineering machinery cement balance weight that guarantees that hole for hoist non-corrosive burn into makes the excavator steady operation, is connected with the excavator base machine Soil stability is provided.

To achieve these goals, the technical solution adopted in the present invention is: New engineering machinery cement balance weight, the iron sheet that comprises cement balance weight main body, coating cement balance weight main body is outer, it is characterized in that: also comprise the installing hole that is positioned at the balance weight bottom and extends internally and form, described installing hole is fixed in support with balance weight.

Aforesaid New engineering machinery cement balance weight, described support is provided with the support holes corresponding with installing hole, and double-screw bolt successively passes installing hole and support holes and then makes balance weight be fixed in support.

Aforesaid New engineering machinery cement balance weight is provided with some balancing weights in the described balance weight.

Aforesaid New engineering machinery cement balance weight, described balance weight is provided with projection, and hole for hoist is set in the projection.

Aforesaid New engineering machinery cement balance weight, described hole for hoist is screwed hole, hole for hoist is threaded with screw plug.

The present invention makes balance weight stablize with the support of excavator base machine main body to be connected by insert same double-screw bolt in installing hole and support holes; By being connected of hole for hoist and screw plug, when balance weight was not lifted, hole for hoist was not corroded by rainwater, and projection has guaranteed that rainwater does not accumulate near hole for hoist; To the counterweight casting cement time, as run into the inhomogenous situation of pouring density, adopt balancing weight to regulate counterweight, guarantee excavator stable operation.

 

Description of drawings

Fig. 1 is structure chart of the present invention;

Wherein, 1 iron sheet is outer, 2 projections, 3 holes for hoist, 4 balancing weights, 5 installing holes, 6 cement balance weight main bodys.

 

The specific embodiment

The invention will be further described below in conjunction with the drawings and specific embodiments.

According to Fig. 1, New engineering machinery cement balance weight, comprise that cement balance weight main body 6(is made of cement), coat the iron sheet skin 1 of cement balance weight main body 6, it is characterized in that: also comprise the installing hole 5 that is positioned at balance weight bottom and extends internally and form, described installing hole 5 is fixed in support with balance weight.Support is provided with the support holes corresponding with installing hole 5, and double-screw bolt successively passes installing hole 5 and support holes and then makes balance weight be fixed in support.Be provided with some balancing weights 4 in the balance weight.Balance weight is provided with projection 2, the projection 2 interior holes for hoist 3 that arrange.Hole for hoist 3 is screwed hole, and hole for hoist 3 is threaded with screw plug (also being a double-screw bolt).

The present invention makes balance weight stablize with the support of excavator base machine main body to be connected by insert same double-screw bolt in installing hole 5 and support holes; By being connected of hole for hoist 3 and screw plug, when balance weight was not lifted, hole for hoist 3 was not corroded by rainwater, and projection 2 has guaranteed that rainwater does not accumulate near hole for hoist 3; To the counterweight casting cement time, as run into the inhomogenous situation of pouring density, adopt balancing weight 4 to regulate counterweight, guarantee excavator stable operation.

Above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops on protection scope of the present invention.
