Problems solved by technology

[0003] The existing methods for processing sand in the hull include two methods. One is to manually enter the hull for sand removal. This method is time-consuming, laborious, and inefficient, which seriously affects the process of shipbuilding. The second is to use a power device to suck out the sand in the hull. , this method consumes a lot of power and costs a lot

Embodiment 1

[0032] This embodiment provides a hull sand cleaning system, such as figure 1 As shown, the hull 1 has a plurality of sand retention areas 2 surrounded by various types of plates. After the hull 1 is subjected to the sandblasting process, the sand or shot blasting media used in the sandblasting process (herein, this medium is simply referred to as sand) will remain in the sand retention area 2 . Since the mass and volume of the hull 1 are relatively large, it is relatively difficult to clean the sand of the hull 1 .

[0033] In order to make the sand cleaning work more time-saving and labor-saving on the premise of ensuring the quality of sand cleaning, the following technical solutions are adopted:

[0034] Circulation holes 3 are provided on the hull 1 and on the plate body enclosing the sand retention area 2, such as figure 1 As shown, the flow holes 3 communicate the adjacent sand retention areas 2 and the outer sand retention areas 2 with the outer side of the hull 1, t...

Embodiment 2

[0045] This embodiment provides a hull sand cleaning system, which is similar to the hull sand cleaning system in the preferred embodiment, except that the sand cleaning platform includes three hydraulic cylinders, and the three hydraulic cylinders can be arbitrarily arranged, The sand cleaning platform can drive the hull to tilt at any angle, for example, the hull tilts diagonally. There are two diagonal lines of the hull, so when tilting along the diagonal, there are four ways of tilting the hull. At this time, the vibration device can be set at the four right angles of the support plate of the sand cleaning platform or at the four a corner.

[0046]On the basis of the above structure, the setting direction of this embodiment is any angle of the hull. Preferably, the setting direction is the diagonal direction of the hull.

Embodiment 3

[0048] This embodiment provides a hull sand cleaning system, which is similar to the hull sand cleaning system in the preferred embodiment 1, except that the specific structure of the sand cleaning platform is different.

[0049] The sand cleaning platform of this embodiment includes a support plate and a movable lifting crane, the support plate is used to fix and support the hull, and the lifting crane can raise a certain part of the hull by a set angle to realize the inclination of the hull. In order to better define the trajectory of the movable lifting crane, the movable lifting crane can be slidably arranged on the sliding rail, and the sliding rail includes a lateral sliding rail and a longitudinal sliding rail.

[0050] The movable lift crane is electrically connected to the control device.

Abstract

The invention provides a hull sand cleaning system and a hull sand cleaning method, and belongs to the field of hull sand cleaning of ships. The problem that for an existing device and method, the sand cleaning efficiency is low is solved. A hull of the sand cleaning system is provided with multiple sand detention areas which are formed by various boards in an enclosed mode, and each sand detention area is communicated to the outer side of the hull directly or indirectly by being communicated with other sand detention areas; the hull sand cleaning system further comprises a sand cleaning platform, and the hull can be arranged on the sand cleaning platform which makes the hull edge incline in one or more set directions and by one or more set angles. The hull sand cleaning method based on the hull sand cleaning system comprises the steps that the hull is inclined through the sand cleaning system, and the sand is discharged out of the outer side of the hull. According to the hull sand cleaning system and the hull sand cleaning method, a hull inclining mode is adopted, sand in all the sand detention areas in the hull gradually flows to the sand detention areas at the edges of the hull and flows out of the hull finally, and the sand cleaning efficiency is high.

Description

technical field [0001] The invention relates to the field of ship manufacturing devices and methods, in particular to a ship hull sand cleaning system and a ship hull sand cleaning method using the system. Background technique [0002] The hull is a hollow body with a specific shape enclosed by the hull and the upper deck, and its interior includes a multi-layer superstructure. When the hull is processed, it is necessary to perform surface treatment such as sandblasting on the various plates that make up the hull. After the hull is sandblasted, a large amount of sand particles will remain inside the hull. Due to the huge hull, the sand particles remain in various areas of the hull. Therefore, the sand cleaning work of the hull is extremely difficult. [0003] There are two existing methods for dealing with sand in the hull. One is to manually enter the hull for sand cleaning. This method is time-consuming and labor-intensive, and has low efficiency, which seriously affects ...
