Description

Technical Field

[0001] This utility model relates to the field of shipbuilding, specifically to a container ship with a tilting mast. Background Technology

[0002] With the development of larger ships, the height of ships is also constantly increasing, especially for large container ships. Due to the increasing number of containers, the height of the superstructure is also increasing. As land transportation is also developing, the number of bridges on canals is increasing, which has put certain restrictions on the height of ships. Therefore, controlling the height of ships is an important means to improve the seaworthiness of ships. The tilting mast is a common means applicable to container ships.

[0003] Most existing tilting masts use a hand-cranked tilting mechanism, which utilizes the lever principle. The upper end of the tilting shaft is connected to the mast body, and the lower end is designed with a certain weight of counterweight. The tilting shaft is connected to the gearbox shaft. By operating the handwheel mounted on the gearbox, the mast is manually tilted. This operation is laborious, and as the torque changes continuously during operation, considerable operating force is required at certain strokes; moreover, it takes a long time to tilt or stand the mast upright. At the same time, the counterweight is difficult to calculate and match, and the manufacturing process is difficult. Often, after installation, the mast cannot be successfully erected, which seriously affects the production schedule. In actual operation, gearbox damage has led to the mast falling, jeopardizing the safety of the crew. Summary of the Invention

[0004] To address the shortcomings of existing tilting mast technologies, this invention provides a tilting mast for container ships that is simple and safe to operate, shortens operation time, and effectively ensures crew safety.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A container ship with a tilting mast includes a lower base welded to the deck of the container ship. A platform plate is welded to the top surface of the lower base, and an upper base is welded to the platform plate. A mast is mounted on the top surface of the upper base, and a tilting base is provided at the bottom of the mast. One side of the tilting base is rotatably mounted on the edge of the top surface of the upper base via a pair of hinges, the axes of which are parallel to the width direction of the container ship. An ear plate is welded to the bottom surface of the tilting base away from the hinges. A telescopic cylinder is installed between the ear plate and the platform plate, and both ends of the telescopic cylinder are hinged to the platform plate and the tilting base, respectively. A hydraulic pump station is installed on the platform plate on one side of the upper base, and the hydraulic pump station is connected to the telescopic cylinder. When the tilting base is in contact with the top surface of the upper base, the tilting base and the upper base are locked by a secondary locking mechanism.

[0007] Furthermore, the secondary locking mechanism includes a horizontal telescopic cylinder, which is fixedly installed on the upper base and connected to the hydraulic pump station. A pin is installed at the telescopic end of the horizontal telescopic cylinder, and the axial direction of the horizontal telescopic cylinder is parallel to the axial direction of the hinge. A pair of vertical fixed lugs are welded to one side of the telescopic end of the horizontal telescopic cylinder on the upper base. A movable lug is welded to the flip base, extending out of the outside of the flip base and corresponding to the pair of fixed lugs. When the flip base is in contact with the top surface of the upper base, the movable lug is inserted between the pair of fixed lugs. Locking holes are respectively provided on the movable lug and the fixed lug. When the horizontal telescopic cylinder extends, the pin passes through the locking holes on the movable lug and the fixed lug.

[0008] Furthermore, a support rod is welded and installed on the platform plate. The bottom end of the support rod is reinforced by welding it to the platform plate through an elbow plate. A U-shaped support plate is installed at the top end of the support rod. When the mast is rotated to a horizontal state, the support plate supports the mast.

[0009] Furthermore, the lower base includes three support legs, each of which is reinforced by welding three circumferentially distributed elbow plates to the deck, and adjacent support legs are connected by welding through connecting pipes.

[0010] Furthermore, the support leg is welded and fixed to the bottom surface of the platform plate by a triangular elbow plate.

[0011] Furthermore, the upper base is composed of two vertical support plates and one horizontal support plate welded together.

[0012] The beneficial effects of this utility model after adopting the above technical solution are as follows: By installing the mast on the base through a hinge, the mast can be tilted and erected using the extension and retraction of a telescopic cylinder. A 90-degree tilt of the mast can be achieved through position switches and auxiliary supports. The telescopic cylinder extension and retraction process is quick and simple to operate. A secondary locking mechanism ensures secondary locking when the mast is erected, improving safety. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0019] like Figure 1 As shown, a container ship with a tilting mast consists of components from bottom to top, including a lower base 1, a platform plate 2, an upper base 3, a mast 4, a telescopic cylinder 5, and a hydraulic pump station 6, which enable the mast to tilt 90 degrees when crossing a bridge at superelevation.

[0020] The lower base 1 mainly consists of three support legs 11, which are triangularly distributed. The bottom surface of each support leg 11 is welded to the deck of the container ship. Each support leg 11 is reinforced to the deck by three circumferentially distributed elbow plates 12. Adjacent support legs 11 are connected by connecting pipes 13, forming a stable overall support structure. The platform plate 2 is supported by the lower base 1 and fixed by welding. The upper end of each support leg 11 is reinforced to the bottom surface of the platform plate 2 by welding triangular elbow plates 14.

[0021] The upper base 3 is fixedly installed on the platform plate 2. The upper base 3 is composed of two vertical support plates and one horizontal support plate welded together. The sides of the vertical support plates are reinforced by welded ribs. The upper base 3 serves as a support for the mast 4 to rotate and tilt.

[0022] The upper end of mast 4 is equipped with radar, searchlights, and other facilities. A tilting base 7 is located at the bottom of mast 4. One side of the tilting base 7 is rotatably mounted on the edge of the horizontal support plate of the upper base 3 via a pair of hinges. The axis of the hinges is parallel to the width direction of the container ship, thus allowing mast 4 to tilt towards the bow. A telescopic cylinder 5 is installed between the platform plate 2 and the tilting base 7. Cylinder seats are welded to the bottom surfaces of both the platform plate 2 and the tilting base 7 on the side away from the hinges. Both ends of the telescopic cylinder 5 are hinged to their corresponding cylinder seats. A hydraulic pump station 6 is installed on the platform plate 2 on one side of the upper base. The hydraulic pump station 6 controls the extension and retraction of the telescopic cylinder 5, thereby pushing mast 4 to tilt and return to its original position.

[0023] A support rod 8 is welded and installed on the platform plate 2. The bottom end of the support rod 8 is reinforced by welding it to the platform plate via an elbow plate. A U-shaped support plate is installed at the top of the support rod. When the mast 4 rotates to a horizontal position, the middle part of the mast 4 is supported by the support plate. After passing over the bridge, the telescopic cylinder 5 retracts, and the mast 4 rotates back to a vertical position. At this time, the telescopic cylinder 5 keeps the mast's position unchanged. To ensure safety, a secondary locking mechanism 9 is installed on the upper base 3.

[0024] The secondary locking mechanism 9 consists of a horizontal telescopic cylinder 91, a pin 92, fixed ear plates 93, and movable ear plates 94. The horizontal telescopic cylinder 91 is fixedly mounted on the horizontal support plate of the upper base 3 and is controlled by a hydraulic pump station 6. The telescopic end of the horizontal telescopic cylinder 91 is mounted with a pin 92 via a mounting base. The axis of the horizontal telescopic cylinder 91 is parallel to the axis of the hinge. A pair of vertical fixed ear plates 93 are welded to one side of the upper base 3 located at the telescopic end of the horizontal telescopic cylinder 91. The movable ear plate 94 is welded to the tilting base 7, extending outward from the outside of the tilting base 7 and corresponding to the pair of fixed ear plates 93. When the mast 4 is reset to the vertical position, the movable ear plate 94 is inserted between the pair of fixed ear plates 93. Locking holes are respectively provided on the movable ear plate 94 and the fixed ear plate 93. At this time, when the horizontal telescopic cylinder 91 extends, the pin 92 passes through the locking holes on the movable ear plate 94 and the fixed ear plate 93 simultaneously, locking the mast 4 in the vertical direction for the second time.
