Abstract

The invention discloses a balance weight for hybrid power engineering machinery. The balance weight comprises a balance weight main body (10), wherein the balance weight main body (10) comprises a casing (11) and a filler (13), the inner space of the casing (11) is separated into a filler cavity (13a) used for installing the filler (13) and an energy storage unit cavity (14a) used for installing an energy storage unit (14), and a wiring hole (12) communicated with the energy storage unit cavity (14) is arranged on the casing (11). The invention also provides the hybrid power engineering machinery comprising the balance weight. After the energy storage unit cavity is arranged in the balance weight, the energy storage unit can be directly arranged in the energy storage unit cavity, and the arrangement of the energy storage unit is convenient.

Description

technical field [0001] The present invention relates to a hybrid construction machine, in particular to a counterweight for a hybrid construction machine and a hybrid construction machine including the counterweight. Background technique [0002] An energy storage unit is provided in a hybrid construction machine. For example, in a hybrid excavator, the energy storage unit and the fuel cell provide electric energy to the hybrid excavator. The energy storage unit can also recover the surplus energy in the construction vehicle, which plays an important role in power balance. The existing energy storage units are simply arranged in the vehicle, but due to the large volume of the energy storage unit, it is difficult to find a separate space for the energy storage unit in the hybrid construction machine. [0003] Therefore, how to reasonably arrange the energy storage units has become an urgent technical problem in this field. Contents of the invention [0004] The object of...
