Description

Mud box cover and mud box with same

technical field

The utility model relates to the field of containers, in particular to a mud box cover and a mud box with the same.

Background technique

Mud boxes (sea mud boxes) are used more and more widely as storage and transportation containers in offshore oil platform operations.

The mud box is divided into an open box and a covered box.

The open mud box is convenient and fast for loading and unloading mud, but the mud will leak out due to bumps during loading and transportation, causing environmental pollution; and external impurities such as rainwater will also enter the box.

The lidded box is divided into a separate top cover and a flip top cover and is on a plane.

For the mud box with separate top cover, before loading and unloading operations, the hard top cover needs to be lifted and placed in other places before the loading and unloading operation can be performed. After loading and unloading, the hard top cover is closed on the top of the mud box and locked; thus It needs to take up a lot of operating space and the removed top cover is easy to lose. The top cover of the larger mud box adopts a two-piece split structure, which is lifted separately during loading and unloading. After loading and unloading, they are respectively covered on the top of the mud box and locked; this not only doubles the workload and operating time, but also doubles the cover. The body overlap is also prone to deformation, resulting in lax sealing, allowing liquids such as rainwater to enter the interior of the box.

In the mud box with a flip top cover, the top cover is fixedly connected to the top and side beams on the rotating side of the mud box through multiple hinge devices, so that the integral top cover can be rotated and opened relative to the box body. When the top cover of the mud box is in the unscrewed state, each top cover needs to be equipped with a special fixing device, which is cumbersome to operate, and exceeds the outer dimensions of the box to occupy a large operating space, which is easy to scratch and hit the staff.
