Abstract

The invention relates to the technical field of trailing suction trolleys, and discloses a trailing suction trolley dredge pump suction port and rotary pipe joint mechanism. The mechanism comprises adredge pump, a rotary pipe joint and a dredge pipe, an upper protective cover is fixedly installed on the top of one end of the rotary pipe joint, a sealing ring is fixedly installed on the top of aninner cavity of the upper protective cover, one side of the bottom of the upper protective cover is fixedly provided with a mounting plate, one side of the mounting plate is fixedly connected with thetop of a lower protective cover, the other end of the rotary pipe joint is in threaded sleeve connection with a ferrule nut, and an inner cavity of the ferrule nut is movably provided with a front ferrule located at one end of the rotary pipe joint. According to trailing suction trolley dredge pump suction port and rotary pipe joint mechanism, a flange at the dredge pump suction port and rotary pipe joint is protected through the upper protective cover and the lower protective cover which are combined, the upper protective cover and the lower protective cover are fixed through the mounting plate, meanwhile, the sealing rings are installed inside the upper protective cover and the lower protective cover, mud water is prevented from entering, and therefore the service life of the joint flange is prolonged.

Description

technical field

[0001] The invention relates to the technical field of a raking suction trolley, in particular to a mud pump suction port and a rotary pipe joint mechanism of a raking suction trolley. Background technique

[0002] The dredging trolley is the key equipment of the dredging technology equipment test platform. Its main function is to complete the model test of the dredging system and key dredging equipment of the three main ship types of dredgers, cutter suction and grab dredgers. The trolley consists of a cart, a horizontal working trolley on the cart, a control system and a power supply system. At the same time, the suction trolley is equipped with an underwater mud pump system. The mud pump in the underwater mud pump system is connected with the dredge pipe. Before connecting, it is necessary to connect the rotary pipe joint first, so that the suction pipe can rotate normally.

[0003] When the existing rotary pipe joint is connected to the suction port of t...
