Combined counterweight for excavator

Technical Field

The invention belongs to the technical field of excavators, and particularly relates to a combined counterweight for an excavator.

Background

Excavators, also known as excavating machines, also known as excavators, are earth moving machines that excavate material above or below a load bearing surface with a bucket and load it into a transport vehicle or unload it to a stockyard.

The materials excavated by the excavator mainly comprise soil, coal, silt, soil subjected to pre-loosening and rocks. In view of the development of construction machines in recent years, the development of excavators is relatively fast, and the excavator has become one of the most important construction machines in construction. The most important three parameters of the excavator: operating weight (mass), engine power and bucket capacity.

Common excavator structures include power devices, working devices, swing mechanisms, operating mechanisms, transmission mechanisms, traveling mechanisms, auxiliary facilities, and the like. The transmission mechanism transmits the power of the engine to actuating elements such as a hydraulic motor and a hydraulic cylinder through the hydraulic pump to push the working device to act, so that various operations are completed.

The effect of excavator counter weight is balanced whole car, and along with the increase of complete machine weight, counter weight size, weight also can increase thereupon, and on large-scale mining excavator, the counter weight that uses can reach dozens of tons, and generally is connected through welding the mode of taking between current counter weight and the excavator, and the dismouting efficiency that leads to the counter weight is lower, and positioning accuracy is relatively poor, changes the loaded down with trivial details that the counter weight can be very, therefore it is necessary to design a combination formula counter weight for the excavator to solve this kind of problem.
