AI Technical Summary

Technical Problem

The existing dredger mud door structure is subjected to large force on the pull rod when closing, is easily deformed and damaged, has poor sealing effect, is difficult to repair and replace, and is difficult to construct.

Method used

A double-conical mud door structure is designed. The upper and lower parts of the mud door are conical and inverted conical respectively. The sealing strip is set on the inverted conical wall. The pull rod is connected by a hinge. The mud door covers the door opening of the door frame from top to bottom. The inverted conical structure naturally supports the mud door and reduces the stress on the pull rod. The sealing strip forms a seal on the conical surface.

Benefits of technology

It reduces the stress on the pull rod and mud door, prolongs the life of the sealing strip, reduces the maintenance frequency, simplifies the maintenance and replacement process, shortens the construction time and improves the construction efficiency.

Abstract

The present invention discloses a double-conical mud door structure for a dredger and a manufacturing method thereof. The double-conical mud door structure comprises a mud door, a pull rod, and a door frame. The upper and lower portions of the mud door are conical and inverted conical, respectively. The lower end of the pull rod is connected to the top of the mud door. The door frame is provided with an inverted conical door opening that matches the lower portion of the mud door. The mud door covers the door opening of the door frame from top to bottom to achieve closure. The lower inverted conical wall of the mud door is provided with an annular sealing strip. This double-conical mud door structure can effectively reduce the stress on the mechanism, ensure sealing, and increase the life of the structure. It is also easy to maintain or construct. The double-conical mud door manufacturing method can efficiently and time-savingly manufacture the mud door and meet structural requirements.
