Problems solved by technology

[0010] However, the volume of the DC charging and discharging unit is generally relatively large. To place it in the upper mechanism 108 requires relatively large changes and will occupy the space of other components or increase the overall size of the upper mechanism.
However, considering the relationship between machine size and operability, the external dimensions of the upper mechanism 108 have to be limited.

Embodiment Construction

[0023] The lower part of the present invention is a walking mechanism, and the upper part is a rotatable mechanism. The upper rotatable mechanism is installed on the lower mechanism 102 of the lower walking mechanism, and the lower mechanism 102 of the lower walking mechanism is provided with a DC charging and discharging unit 106. 105 of the installation space.

[0024] The lower mechanism 102 has a box-like main structure 104 , and the installation space 105 is inside the main structure 104 .

[0025] The installation space 105 is located between the two track beams 115 on the side of the guide wheel.

[0026] The installation space 105 is located between the two track beams 115 on one side of the driving wheel.

[0027] attached figure 1 to attach image 3 It is a drawing of the construction machine in the first embodiment of the present invention. attached figure 1 It is the three-dimensional view of the main part of the lower mechanism, attached figure 2 It is a ...

Abstract

The invention discloses a construction machine of which an upper mechanism can be rotatably arranged on a lower mechanism. The construction machine is characterized in that: a lower mechanism of a lower travelling mechanism is provided with installation spaces for placing direct-current charging and discharging units; and the installation spaces can be formed on one side near front idlers between two track beams, and can also be formed on one side near driving wheels between two track beams. The construction machine has the advantages that: the spaces of the lower mechanism are fully utilized, and functional parts with large volumes and high quality can be increased on the premise that the size and the rotation mass the upper mechanism are not increased; moreover, a rack of the lower mechanism is strong enough, so the phenomenon that the machine hits rocks and the direct current charging and discharging units are damaged during travelling can be avoided.

Description

technical field [0001] The invention relates to a construction machine in which an upper mechanism is rotatably installed on a lower mechanism. Background technique [0002] Generally, a construction machine is composed of an upper body equipped with working devices, power units, operation control equipment, cab and other equipment, and the upper body is rotatably mounted on the lower body of the movable machine. [0003] An example can be given, for example, a hydraulic excavator representing this type of machinery. like Figure 7 In the perspective view shown in , the hydraulic excavator is equipped with a lower body 102 and a swing upper body 108 . The lower mechanism 102 is crawler type, and the sprocket 113 thereon and the crawler belt 112 wound on the sprocket 113 are alternately / simultaneously operated by operating the left and right traveling hydraulic motors individually. [0004] The rotating upper body 108 is mounted on the lower body 102 via a slewing bearing, ...
