Title:
CENTER OF GRAVITY ADJUSTING DEVICE, CONSTRUCTION MACHINE, AND DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/184766
Kind Code:
A1
Abstract:
A center of gravity adjusting device, a construction machine, and a detection device. The center of gravity adjusting device comprises a counterweight mechanism (2) and a telescopic driving mechanism (5), the counterweight mechanism (2) is rotatably connected to the tail of a construction machine (1), and the telescopic driving mechanism (5) is configured to drive the counterweight mechanism (2) to rotate relative to the construction machine (1). When the device is used, the counterweight mechanism is pushed and pulled by means of the telescopic driving mechanism, so that the counterweight mechanism can rotate relative to the construction machine, and in the rotating process, the counterweight mechanism can adjust fore and aft torque of the construction machine, so that the center of gravity positions of the construction machine and the counterweight mechanism are adjusted, and the defect caused by mutual connection of the counterweight mechanism and the construction machine by using a telescopic beam structure in the construction machine can be overcome.
