A mud pump suction port and rotary pipe joint mechanism of a raking suction trolley

Abstract

The invention relates to the technical field of rake suction trolley, and discloses a mud pump suction port and rotary pipe joint mechanism of a rake suction trolley, including a mud pump, a rotary pipe joint and a mud suction pipe. Protective cover, the top of the inner cavity of the upper protective cover is fixedly installed with a sealing ring, one side of the bottom of the upper protective cover is fixedly installed with a mounting plate, one side of the mounting plate is fixedly connected with the top of the lower protective cover, and the other end of the rotary pipe joint is threaded A ferrule nut is sleeved, and the inner cavity of the ferrule nut is movably installed with a front ferrule located at one end of the rotary pipe joint. The mud pump suction port and rotary pipe joint mechanism of the rake suction trolley protects the flanges at the mud pump suction port and the rotary pipe joint through the combined upper protective cover and the lower protective cover. The protective cover is fixed, and sealing rings are installed inside the upper protective cover and the lower protective cover to prevent muddy water from entering, thereby improving the life of the joint flange.

Description

Technical field [0001] The present invention relates to the field of smoke-suction trolleys, and is specifically a hardened vehicle mud pump suction and a rotary pipe joint mechanism. Background technique [0002] The hardened trolley is a key device for the dredging technology equipment test platform. Its main role is to complete the dredging system and the model test of the three-class main ship type of dredges and key dredging machines, and suction The trolley is composed of a large car and a transverse working trolley on the big car, the control system and power supply system, and the harder vehicle is equipped with underwater mud pump system, of which the mud pump in the water mud pump is in the suction tube Need to connect to the rotating tube joint before the connection, so that the drum can be rotated normally. [0003] When the existing rotary pipe joint is connected to the suction port of the mud pump, it is mostly connected to the flange, but the working environment of...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a mud pump suction port and rotary pipe joint mechanism of a raking suction trolley, which is equipped with protection for the mud pump suction port and the flange plate of the rotary pipe joint, ensuring that the mud suction pipe and the rotary pipe joint are assembled in place to prevent muddy water The advantage of entering the ferrule nut solves the problem that when the existing rotary pipe joint is connected to the suction port of the dredger pump, it is mostly connected through a flange, but the working environment of the raking suction trolley is poor, and there is a large amount of muddy water. It is easy to corrode the flange plate, making it difficult for the staff to disassemble the joint from the mud pump or cause corrosion of the seal assembly at the joint between the joint and the mud pump, which affects the sealing effect between the joint and the suction port of the mud pump. When connecting with the suction pipe, it is impossible to ensure whether the suction pipe is firmly connected to the joint or assembled in place, so that the firmness and sealing between the suction pipe and the rotary pipe joint cannot be guaranteed.
