Abstract
The invention proposes a device for dredging manholes, rainwater and wastewater wells, including: a load-bearing unit, a lifting unit, and a monitoring unit. The load-bearing unit consists of: an upper frame (1A) and a lower frame (1B) connected by a vertical frame (1C), a support frame (1D), and reinforcing bars (2B) of the horizontal bar (2), and reinforcing pads (2A). Rings (1E) and wheels (8) are added to the upper frame (1A) and lower frame (1B) respectively. The lifting unit consists of a crane (3) that can be extended / retracted. Winches (4) combined with guide pulleys (4A) control the grab bucket (4B). A rotating movement unit can control the crane (3) to rotate left and right, and connects the head position of the crane (3) to the horizontal bar of the support frame (1D) in the load-bearing unit, through a rotating shaft (3A). The second position of the crane (3) is connected to the horizontal bar (2) through a system consisting of: a rotating column (3A) connected to the trolley (3B), and connected to the rotating frame (3C).The monitoring unit has at least one camera (6) monitoring the operation of the equipment. The generator (5) provides power to the electrical equipment. The electrical panel integrates the electrical box (5A) and the control box (5B) to operate the electrical equipment.
