Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a tilting structure for a construction machine in which the upper rotating body is tilted and held horizontally according to the inclination of the lower traveling body, which is a covered type, the lower traveling body runs in a pair of left and right. A tilting frame is pivotally connected to the left and right sides of a vehicle body frame that supports the upper revolving structure, each tilting frame is pivotally connected to the track frame of the separated traveling device, and the vehicle body frame A tilting structure for construction machinery, characterized in that a tilting frame and a tilting frame are connected so as to be tiltable left and right by expansion and contraction of a tilting cylinder, so that the left and right traveling devices can be tilted separately. (2) the tilting frame has a lower surface portion parallel to and pivotally connected to the vehicle body frame below the vehicle body frame, and an upper surface portion above the tilting frame parallel to and pivotally connected to the truck frame above the truck frame;
2. The tilting structure for a construction machine according to claim 1, comprising an inclined surface section connecting the lower step surface section and the upper step surface section, and a tip end of the tilting cylinder being pivotally attached to the surface side of the inclined surface section. (3) In the tilting structure of construction machinery, which tilts the upper rotating body according to the inclination of the lower traveling body and holds it horizontally, the lower traveling body is separated into a pair of left and right traveling units, and the upper Tilting frames are pivotally connected to the left and right sides of a vehicle body frame that supports the revolving structure, each tilting frame is pivotally connected to the track frame of the separated traveling device via a shock absorber, and the vehicle body frame and the tilting frame A tilting structure for construction machinery, characterized in that the left and right traveling devices can be tilted independently by connecting them so that they can tilt in the left and right directions by expanding and contracting a tilting cylinder. (4) The tilting frame has a lower surface section that is parallel to the vehicle body frame below and pivotally connected to the vehicle body frame, and a lower surface section that is parallel to the vehicle body frame at a position above the lower surface section that is parallel to the truck frame and is connected to the truck frame via the first shock absorbing device. It consists of an upper surface section that is pivotally mounted, and an inclined surface section that connects the lower surface section and the upper step surface section, the tip of the tilting cylinder is pivotally attached to the front side of the inclined surface section, and the base end is mounted on the back side of the inclined surface section. 4. The tilting structure for a construction machine according to claim 3, wherein a tip of the second shock absorber is pivotally attached to the frame. (5) The shock absorber includes a first rod whose tip is pivotally connected to the traveling device and which can move up and down, and which is built in with an elastic shock absorbing material so as to be compressed so as to be resilient when rising.
and a second buffer part whose upper end is pivotally connected to the tilting frame and which has an elastic buffer material built into the upper end of the first cylinder so as to be resiliently compressed when rising. A tilting structure for a construction machine according to claim 3.
