Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are described in detail.

Please refer to fig. 1, fig. 2 and fig. 3, the platform device for assisting in reamer cleaning and maintenance of the present invention comprises a floating box 4, a groove 7 is provided at the front middle position of the floating box 4, a mounting base 12 is provided at the rear middle position of the floating box 4, and a propeller 1 is mounted on the mounting base 12. Wherein the propeller 1 is used for providing a sailing propulsion function, and the groove 7 is used for placing the reamer assembly 13.

In this embodiment, the buoyancy tank 4 includes a metal frame located inside, and the outer side of the metal frame is welded with the tank plates, and the adjacent tank plates are sealed and fixedly connected.

Further, the length of the buoyancy tank 4 is 3400mm, the width is 2800mm, and the height is 650 mm; the grooves 7 have a length of 1400mm, a width of 1000mm and a depth of 150 mm. In the actual building process, the size of the buoyancy tank 4 is matched with the model of the cutter suction dredger facility, and the size of the groove 7 is matched with the size of the reamer component 13.

In this embodiment, the propeller 1 is selected as an electric propeller, and an environment-friendly propulsion method is adopted. The electric propeller thruster comprises a motor, a shaft sleeve and a rotating shaft, wherein an output shaft of the motor is in butt joint with the upper end of the rotating shaft, an impeller is arranged at the lower end of the rotating shaft, the electric propeller thruster also comprises a storage battery and a controller, and the storage battery and the motor are electrically connected with the controller; the shaft sleeve is arranged on the mounting base 12 through a bearing; the device also comprises an operation rod for adjusting the heading. The whole propeller thruster 1 is operated by the left-right swinging of the operating rod, so that the propelling direction generated by the impeller is changed, and the navigation direction of the whole platform device is adjusted.

Be equipped with first side guardrail 2 and second side guardrail 10 respectively in the both sides of flotation tank 4, these two guardrails provide safeguard function from the both sides of flotation tank 4, avoid operating personnel to drop from flotation tank 4. In this embodiment, as shown in the figures, both the first side guard rail 2 and the second side guard rail 10 are L-shaped, with a front portion extending to the front edge of the deck of the pontoon 4 and a rear portion extending to both sides of the mounting base 12. The front portions of the two guard rails do not extend bent inwards, which leaves sufficient space for the front portions to operate the reamer assembly 13.

A first bollard 6 and a first cable 5 thereof, a second bollard 8 and a second cable 9 thereof are respectively arranged on two sides of the front part of the deck of the buoyancy tank 4, and the bollards and the cables are used for being connected with a bridge bolt of the reamer assembly 13 when the reamer assembly 13 is placed in the groove 7, so that the reamer assembly 13 and the platform device are connected into a whole, and the stability is improved. In this embodiment, both the first 6 and second 8 bollards are selected as cross bollards.
