Problems solved by technology
Cutter suction dredgers with double cutter heads cannot adapt well to the more complex underwater environment
Therefore, we are in urgent need of a device that can distribute power to the double-cutter heads on the cutter-suction ship, so as to solve the shortcomings of the existing double-cutter head operations on the cutter-suction ship.

The invention discloses a double-cutter-head power distribution device for a cutter suction dredger based on a differential mechanism. The double-cutter-head power distribution device comprises a main shaft connected with an engine, wherein the main shaft is connected with the differential mechanism; a transmission shaft of the differential mechanism is respectively connected with two half shafts; each half shaft is connected with a hydraulic oil pump; the hydraulic oil pump is connected with hydraulic motors of the cutter heads by virtue of an oil conveying tube; the hydraulic motors drive the cutter heads to work; electronic brakes are respectively arranged on the two half shafts; a hydraulic sensor and a flow velocity sensor are arranged in the oil conveying tube; acquired data is transmitted to an electric control center by virtue of the hydraulic sensor and the flow velocity sensor; the electric control center is used for controlling the electronic brakes on the two half shafts according to the data so as to control rotation speed of the two cutter heads. The invention further provides a double-cutter-head power distribution method for the cutter suction dredger based on the differential mechanism. According to the device and the method, rotation speed of the cutter heads at the two sides can be automatically coordinated, so that cutter suction efficiency of the cutter suction dredger is improved.
Description
technical field [0001] The invention belongs to the field of power distribution of double-cutter cutter heads, and in particular relates to a power distribution device and method for double-cutter cutter heads of a cutter suction ship based on a differential. Background technique [0002] The reamer head is the core excavating component of a cutter suction dredger, and its operating status is very important to the cutting system and even the operating efficiency of the entire ship. The reamer head is a tool specially used to loosen the soil on the cutter suction dredger. Compared with the single reamer head cutter suction dredger, the dredger with double reamer head has a great improvement in work efficiency. shortcoming. [0003] When a cutter suction dredger with double cutter heads is operating, the working water area cannot be all flat, and there is a certain slope in some places, and there are also differences in the environment of the working water area on both sides ...
