Embodiment 1

[0022] figure 1 Shows a partial structural diagram of the dredger in this embodiment, figure 2 Shows the structure diagram of the anti-falling mud door of this embodiment, image 3 It is a top view of the anti-falling mud door. Referring to the figure, the anti-falling mud door of this embodiment includes a mud door body 4 that matches the mud outlet 3 and a plurality of mud door bodies 4 radially distributed with the center of the mud door body 4 as the center. Mud door reinforcement plate (not marked in the figure), the mud door reinforcement plate is perpendicular to the mud door body 4, the upper part of each mud door reinforcement plate is provided with a blocking member 5, the mud door body 4 The distance to the edge of the blocking member 5 is greater than the radius of the mud discharge port 3, which can satisfy that when the mud door falls to the position of the blocking member 5, the blocking member 5 is blocked on the mud discharge port 3. The mud door fell and sank...

Embodiment 2

[0026] This embodiment provides a dredger with the anti-falling mud door of embodiment 1, and its partial structure can be referred to figure 1 and figure 2 As shown, the bottom of the mud tank of the dredger is provided with a mud outlet 3, and the mud door is provided at the mud outlet 3. The upper part of the mud door is connected with the tie rod 2 of the hydraulic cylinder on the deck surface through a connecting flange 6 During the mud loading process, the mud door is tightened by the pull rod 2 to close the mud door. When the mud is discharged, the mud door can be opened by moving the pull rod 4 downward. If the mud door falls off the pull rod 2 accidentally, the mud door will not fall into the seabed and can be blocked on the mud discharge port 3 by the blocking member 5.

[0027] In this embodiment, the mud discharge port 3 is provided with a reinforcing part, the position of the reinforcing part corresponds to the position of the blocking member 5, and the thickness of ...

Abstract

The invention relates to a dredger and discloses an anti-falling hopper door and a dredger. The anti-falling hopper door comprises a hopper door body and multiple hopper door reinforcement plates, wherein the hopper door body is matched with a mud discharge port; the multiple hopper door reinforcement plates are distributed radially around the center of the hopper door body as a circle center; the hopper door reinforcement plates are perpendicular to the hopper door body; the upper part of each hopper door reinforcement plate is provided with a clamping and blocking piece; the distance from the center of the hopper door body to the edge of each clamping and blocking piece is greater than the radius of the mud discharge port. Through the arrangement of the clamping and blocking pieces on the hopper door body, the anti-falling hopper door and the dredger can realize that when falling from a connecting piece, the hopper door is clamped and blocked at the mud discharge port so as not to fall into the sea, and therefore, the damage to a dredger body and marine accidents are prevented; when the falling hopper door strikes a dredger bottom, the safety of the dredger body can be guaranteed through a reinforcement design of a corresponding part on the mud discharge port; the whole structure is simple; the construction cost is low.

Description

Technical field [0001] The invention relates to a dredger, in particular to an anti-dropping mud door and a dredger having the anti-dropping mud door. Background technique [0002] There is a mud outlet at the bottom of the mud tank of the existing dredger, and a mud door is arranged at the mud outlet. The upper part of the mud door is connected with the tie rod of the hydraulic cylinder on the deck surface through a connecting flange. During the mud loading process, The mud door is closed by pulling the rod tightly. When the mud is discharged, the mud door can be opened by moving the rod down. [0003] Due to factors such as long-term stress and corrosion of the tie rod, when an accident occurs, if the tie rod is damaged and the mud door falls off the tie rod, the mud door falls into the seabed, causing damage to the hull and marine damage. Summary of the invention [0004] (1) Technical problems to be solved [0005] The purpose of the present invention is to provide an anti-falli...
