The invention relates to the technical field of ship hoisting, in particular to a non-welded segmented crane.

Background technique

At present, when the ship is hoisted in sections, the crane is usually welded on the corresponding hull structure, and then hoisted. Although this method can also meet the purpose of hoisting the ship, after the hull is hoisted, the staff After the hull is folded and installed on the ship, it is necessary to manually dismantle the crane through a cutter or a carbon planer. This operation requires fixed resources consumption, increases the cost of shipbuilding, and requires high staff. Operate the machine, and the paint on the ship will be damaged to a certain extent during the dismantling process. Therefore, after the crane is dismantled and installed, the staff also needs to repaint the ship. Due to the special working environment of the ship itself, resources are relatively scarce.

In view of the above situation, it is necessary to improve the existing way of hoisting ships in sections, so that it can meet the needs of the cost and labor intensity of hoisting ships in sections.

The purpose of the present invention is to solve the problem that the existing segmented hoisting method is usually fixed on the hull by welding, and then other machines need to be operated to disassemble the hull after the hull is closed. This operation method is complicated and requires high staff. In addition, the paint on the ship will be damaged during the disassembly process, which increases the cost of shipbuilding and greatly increases the labor intensity. Therefore, we designed a non-welded segmented crane, which has a simple structure, convenient disassembly, and low labor intensity. It can be recycled and used, which reduces the cost of shipbuilding.

The technical solution of the present invention to achieve the above objects is that a non-welded segmented crane includes a connecting base plate and bolts, and end U-shaped clips are respectively arranged around the connecting base plate, and the end U-shaped clips are in the shape of a connecting plate. U-shaped, one end of the end U-shaped clip close to the open end of the connecting base plate is also provided with a threaded sleeve, and the threaded sleeve is longitudinally penetrating; during operation, one end of the end U-shaped clip is open against the connecting base plate. The other end of the upper surface abuts against the lower surface of the T-shaped row mechanism, the bolt passes through the threaded sleeve and the bottom of the bolt abuts on the upper surface of the connecting base plate, and is locked by the thread fit of the bolt and the threaded sleeve.

As a further supplement to the technical solution, the middle part of the connecting bottom plate is symmetrically provided with a middle U-shaped clip.

As a further supplement to the technical solution, there are four U-shaped clips in the middle part, and two of them are arranged on the upper and lower sides of the middle part of the connecting bottom plate.

As a further supplement to the technical solution, the middle position of the connecting base plate is provided with a main board for spacing the middle U-shaped clips symmetrical on the upper and lower sides.

A further supplement to this technical solution, an ear plate is provided between the U-shaped clip at the end and the U-shaped clip in the middle, and two ear plates are provided on the left and right sides of the main board, respectively. It is fixedly connected to the upper surface of the connection base plate.

As a further supplement to the technical solution, the connecting bottom plate is provided with a conical pit below the corresponding bolt, and the size of the conical pit matches the size of the bolt.

The beneficial effect is that, without welding, the connecting bottom plate is placed between the hull structures that are hoisted in sections, and then the connecting bottom plate and the hull structure are connected through U-shaped clips, the operation is simple, the use effect is good, and it can be used repeatedly. Moreover, after the hull is closed, there is no need to remove the crane by a cutter or a carbon planer, and the crane can be removed only by removing the bolts, which reduces labor intensity and shipbuilding cost, and is convenient for people to use widely.

Detailed ways

This technical solution is based on the fact that the existing ship hoisting method is complicated and the effect is not very good, and the shipbuilding cost is further increased in the operation process, and the labor intensity is relatively large, this method is not suitable for our growing needs. , so we designed this technical solution to solve the problems existing in the existing hoisting methods.

In order to make the technical solution more clear to those skilled in the art, the specific structure and principle of the technical solution will be described below with reference to the accompanying drawings 1-4: It needs to be tightened by bolts 4; the present invention includes a connecting bottom plate 1 that plays a connecting role, and during operation, the connecting bottom plate 1 is closely abutted on the sectional hull structure of the ship; in order to fix the connecting bottom plate 1, the segmented structure is installed Together, the connecting bottom plate 1 is respectively provided with end U-shaped clips 3 around the connecting bottom plate 1 for fixing the connecting bottom plate 1 on the T-shaped row mechanism 2 on the hull structure; the following will describe the end U-shaped clips 3. How to realize the fixing effect will be further elaborated. The end U-shaped clip 3 is U-shaped. When working, one end of the U-shaped clip 3 is open against the upper surface of the connecting base plate 1, and the other end is against the lower surface of the T-shaped row mechanism 2. , In order to facilitate the connection and locking, the end U-shaped clip 3 is provided with a threaded sleeve 31 at the open end of the connecting base plate 1, and the threaded sleeve 31 is longitudinally penetrated. During operation, the bolt 4 passes through the threaded sleeve 31 and the bolt 4. The bottom is abutted against the upper surface of the connecting base plate 1, and the bolts 4 are engaged with the threads of the threaded sleeve 31 to be locked.

Since there are end U-shaped clips 3 around the connecting base plate 1, the middle part of the connecting base plate 1 is relatively weak during operation. The middle U-shaped clip 5 is symmetrically arranged, and the middle U-shaped clip 5 and the end U-shaped clip 3 work in the same way, both of which are matched by the bolt 4 and the threaded sleeve 31, and then the bottom of the bolt 4 is pressed against the connecting base plate 1. The upper and lower sides of the middle part of the connecting bottom plate 1 are also provided with four U-shaped clips 5 in the middle part, so that the segmented hull structure is Can be installed and fixed better.

Since the middle U-shaped clips 5 adjacent to the upper and lower sides are installed, there is a gap between the two on the connecting base plate 1, which is easy to cause the connecting base plate 1 at the gap to be deformed. Therefore, in the middle position of the connecting base plate 1 There is a main board 6 for spacing the middle U-shaped clips 5 symmetrical on the upper and lower sides.

Since the end U-shaped clip 3 and the middle U-shaped clip 5 are both installed on the connecting base plate 1, the gap between them is easily deformed. An ear plate 7 is provided between the clip 3 and the middle U-shaped clip 5. The ear plate 7 is provided with two and is respectively arranged on the left and right sides of the main board 6. The ear plate 7 is connected to the connection base plate 1. Surface fixed connection.
