Description

Technical Field

[0001] The utility model belongs to the technical field of ship facilities, and in particular relates to a temporary covering device. Background Art

[0002] During the construction of various projects, various types of construction vessels generally involve the transportation of construction materials and temporary modifications to the vessels. The transported construction materials are placed on the deck of the vessel and unloaded after arriving at the construction destination. Temporary modifications to the vessel include adding / removing auxiliary facilities and welding / cutting ship facilities to adjust the height of the vessel (usually corresponding to the height limit requirements when passing under a bridge). In this way, some deck areas on the ship become temporary storage areas for materials and temporary areas for modification and construction. Since ship facilities are usually faced with changeable climatic conditions, such as rainy days, the aforementioned temporary storage areas for materials and temporary construction areas need to be temporarily covered and shielded to prevent rain from affecting the materials. At the same time, by covering and shielding specific areas, the construction area is protected from rain erosion.

[0003] Tarpaulins are commonly used for this purpose. However, due to the large area to be covered, and the lack of reliable support when stacked above the area, tarpaulins can trap water. As the water settles under the influence of gravity, it can be pierced by sharp edges of materials and equipment below, leading to leakage and loss of effective coverage. Therefore, a temporary covering device is needed to address these technical issues. Utility Model Content

[0004] The purpose of the utility model is to provide a temporary covering device, which forms a covered three-dimensional space below, avoids the problems of water accumulation and leakage in the tarpaulin, and provides a stable and reliable regional covering and shielding effect.

[0005] The technical solution adopted by the utility model is: a temporary covering device, including a combined central support frame dropped on the deck of a ship, a plurality of ear plates with holes for connection are installed on the top edge of the central support frame, a plurality of temporary rings are provided at the edge of the covering area demarcated on the deck of the ship, an oblique rope assembly is installed between each ear plate with holes of the central support frame and the corresponding temporary ring, the oblique rope assembly includes an oblique rope with an oblique rope tightener in the middle, a first hook for connecting to the ear plate with holes is provided at one end of the oblique rope, and a second hook for connecting to the temporary ring is provided at the other end, and also includes an annular connecting rope for connecting each oblique rope assembly in sequence, and a plurality of annular connecting ropes are provided along the length direction of the oblique rope assembly; and also includes a tarpaulin, which is provided above the central support frame and the support net composed of the oblique rope assembly and the annular connecting rope.

[0006] Preferably, a plurality of rope loops are provided on the inclined rope, the annular connecting rope passes through the rope loops, and an annular rope tightener is provided on the annular connecting rope.

[0007] Preferably, the central support frame includes a main frame in the shape of a rectangular parallelepiped, with main frame ear plates installed at the four corners of the top of the main frame, an extension frame provided in the front middle of the main frame, and an extension frame ear plate provided at the top front of the extension frame, and the main frame and the extension frame are detachably connected.

[0008] Preferably, connecting frames are installed between the front sides of the main frame and the front sides of the extension frame, and the rear of the connecting frame is detachably connected to the main frame, and the front of the connecting frame is detachably connected to the extension frame.

[0009] Preferably, the temporary collar is fixed on the ship deck by spot welding.

[0010] Preferably, the middle of the sheet is fixed to the central support frame, the inclined rope assembly and the annular connecting rope by elastic clips, and the edges of the sheet are fixed by being pressed by heavy objects.

[0011] The advantages and positive effects of the utility model are:

[0012] The present invention provides a temporary covering device. Compared to existing covering methods that use tarpaulins directly covering an area, the temporary covering device in the present invention is a three-dimensional covering device that can form a three-dimensional space below. Because the central support frame and support net provide good support for the tarpaulin, the tarpaulin is effectively prevented from coming into contact with the materials and facilities below, avoiding problems such as wear and puncture of the tarpaulin. Because the tarpaulin is set on the central support frame and the support net composed of the inclined rope assembly and the annular connecting rope, the tarpaulin is strongly supported, forming a shape that is high in the middle and low around the edges. In this way, rainwater falling on the tarpaulin can be smoothly transferred to the surrounding areas, effectively avoiding the problem of water accumulation.

[0013] On the other hand, since the central support frame is connected to the temporary ring on the ship deck using multiple inclined rope assemblies and an inclined rope tightener is provided in the middle of the inclined rope assembly, the central support frame can be stably maintained in the center position of the designated coverage area by tightening the inclined rope assembly, avoiding arbitrary displacement under the influence of wind and other factors. Therefore, the temporary covering device in the present invention provides a more stable covering and shielding effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given to illustrate in detail.

[0020] See Figure 1 The temporary covering device of the present invention includes a modular central support frame 1 that falls on the deck of a ship. A plurality of ear plates with holes for connection are installed on the top edge of the central support frame 1. A plurality of temporary rings 5 ​​are provided at the edge of a covering area 4 defined on the deck of the ship. A diagonal rope assembly 2 is installed between each ear plate with holes of the central support frame 1 and the corresponding temporary ring 5. The device also includes an annular connecting rope 3 that connects each diagonal rope assembly 2 in sequence. A plurality of annular connecting ropes 3 are provided along the length direction of the diagonal rope assembly 2.

[0021] The central support frame 1 and the support net composed of diagonal rope assemblies 2 and annular connecting ropes 3 together form a support system that is high in the middle and low around the edges. The central support frame 1 is designed as a modular structure so that its shape can be adjusted according to on-site needs. The diagonal rope assemblies 2 secure the central support frame 1 to the middle of the designated coverage area 4 on the ship's deck, preventing arbitrary displacement of the central support frame 1. The diagonal rope assemblies 2 also serve as the skeleton of the support net. The annular connecting ropes 3 are used to reduce the size of the gaps between adjacent diagonal rope assemblies 2. Therefore, when viewed from above, this temporary covering device has a structure similar to a spider web.

[0022] It also includes a tarpaulin (not shown in the figure), which is arranged above the central supporting frame 1 and the supporting net composed of the oblique rope assembly 2 and the annular connecting rope 3. The tarpaulin is used to prevent rainwater from entering the three-dimensional space below. At the same time, since the supporting system is high in the middle and low on all sides, the tarpaulin is high in the middle and low on all sides. In this way, rainwater falling on the tarpaulin is transferred to the surroundings and slides down, which can effectively avoid the problem of water accumulation.

[0023] See Figure 2 , we can see that:

[0024] The central support frame 1 comprises a rectangular main frame 1-1, with main frame lugs 1-2 mounted at the four corners of the main frame 1-1. An extension frame 1-3 is located in the front center of the main frame 1-1, and extension frame lugs 1-5 are located at the top front of the extension frame 1-3. The main frame 1-1 and extension frame 1-3 are detachably connected. As shown in the figure, the extension frame 1-3 is rectangular and has the same height as the main frame 1-1. Both the main frame 1-1 and the extension frame 1-3 are welded together using strip steel plates. A connection hole is provided in the front center of the main frame 1-1 and in the rear center of the extension frame 1-3. The main frame 1-1 and the extension frame 1-3 are fixed together using bolts located in the connection holes.

[0025] In this embodiment, connecting frames 1-4 are installed between both sides of the front of the main frame 1-1 and both sides of the front of the extension frame 1-3. The rear portion of the connecting frame 1-4 is detachably connected to the main frame 1-1, and the front portion of the connecting frame 1-4 is detachably connected to the extension frame 1-3. As shown in the figure, the connecting frame 1-4 is a planar frame, and its height is the same as that of the main frame 1-1 and the extension frame 1-3. It is welded from strip steel plates. Connecting holes are provided on both sides of the front of the main frame 1-1 and the extension frame 1-3, and connecting holes are provided on the rear and front edges of the connecting frame 1-4. The connecting frame 1-4 is fixed to the main frame 1-1 and the extension frame 1-3 by bolts located in the connecting holes.

[0026] The connecting frames 1-4 mainly play the role of strengthening the overall structural strength. Since the central support frame 1 is a modular structure, the structural type can be adjusted and set as needed on site, that is, the main frame 1-1 can be used alone, or the main frame 1-1 and the extension frame 1-3 can be used at the same time, or the main frame 1-1, the extension frame 1-3 and the connecting frame 1-4 can be used at the same time.

[0027] See Figure 3 , we can see that:

[0028] The diagonal rope assembly 2 includes a diagonal rope 2-4 with a diagonal rope tensioner 2-3 in the middle. One end of the diagonal rope 2-4 is provided with a first hook 2-1 for connecting to the perforated lugs (main frame lug 1-2 and extension frame lug 1-5), and the other end is provided with a second hook 2-5 for connecting to a temporary ring 5. The diagonal rope tensioner 2-3 is used to tension the diagonal rope 2-4 to ensure an all-directional pulling effect on the central support frame 1. The diagonal rope tensioner 2-3 uses an existing tensioner, and its structure and function are not described in detail here.

[0029] In this embodiment, multiple loops 2-2 are provided on the diagonal rope 2-4, through which the circular connecting rope 3 passes. A circular rope tightener is also provided on the circular connecting rope 3. The loops 2-2 are used to define the longitudinal position of the circular connecting rope 3 but are not fixed to the circular connecting rope 3. In other words, the circular connecting rope 3 can move freely within the loops 2-2. The loops 2-2 can be formed by fastening buckles at corresponding locations on the diagonal rope 2-4, or they can be metal rings attached to the diagonal rope 2-4 using methods such as crimping.

[0030] In this embodiment, the temporary collar 5 is fixed to the ship's deck by spot welding. After the temporary covering device is used, the temporary collar 5 is removed. When installing the inclined rope assembly 2, its first hook 2-1 is hooked on the perforated lug plate, and its second hook 2-5 is hooked on the temporary collar 5. Then, the inclined rope tensioner 2-3 is operated to tighten the inclined rope.

[0031] After the oblique rope assembly 2 is passed through the rope ring 2-2, the ends are connected as a whole through a buckle. Then the annular rope tightener is operated to tighten the annular connecting rope 3. The oblique rope assemblies 2 and the annular connecting rope 3 in the tensioned state together constitute a tensioned support net, providing a stable support function for the tarpaulin, preventing the tarpaulin from accumulating water and collapsing due to rain erosion.

[0032] In this embodiment, the middle part of the tarpaulin is fixed to the central support frame 1, the diagonal rope assembly 2 and the annular connecting rope 3 by elastic clips, and the edges of the tarpaulin are fixed by heavy objects. This can significantly improve the tarpaulin's ability to stabilize itself when it is washed by rain and subjected to wind.

[0033] How to use:

[0034] Assemble the central support frame 1 at the center of the covered area 4 defined on the ship's deck and place it in a stable upright position; extend the perforated ear plates radially outward to the edge of the covered area 4 to determine the positions of the temporary collars 5, and then install the temporary collars 5 at these positions by spot welding; then install the diagonal rope assembly 2 between the perforated ear plates of the central support frame 1 and the corresponding temporary collars 5, and operate the diagonal rope tighteners 2-3 to tighten the diagonal rope assembly 2; then install multiple annular connecting ropes 3 and operate the annular rope tighteners to tighten the annular connecting ropes 3;

[0035] Then, tarpaulin is laid on top. After the tarpaulin is laid, multiple elastic clips are used to fix the tarpaulin to the top frame of the central support frame 1, the inclined rope assembly 2 and the annular connecting rope 3 at multiple positions, and heavy objects are pressed on the outer edge of the tarpaulin.
