Description

Technical Field

[0001] This utility model relates to the field of ship maintenance technology, specifically a portable ship maintenance support device. Background Technology

[0002] Ships use a wide variety of equipment, including steering equipment, lifting equipment, anchoring equipment, mooring equipment, lifesaving equipment, tug and towing equipment, navigation and signaling equipment, and mooring equipment. These equipment are exposed to salt spray, moisture, and seawater for extended periods, and are subject to corrosion from seawater and marine organisms, which greatly affects the safety of their use. Therefore, the maintenance of ship equipment is of great importance.

[0003] In ship maintenance operations, the maintenance platform is a core tool for ensuring the safety of maintenance personnel and improving operational efficiency. Existing ship maintenance platforms suffer from the following technical problems: Their overall size is too large, making them prone to interference with other equipment or structures when deployed within the limited deck or cabin space of a ship; their adaptability is poor, requiring significant storage space even after being stowed. Given the limited space available for tool storage on ships, the platform's stowage characteristics further exacerbate the conflict between space resource constraints and the overall ease of use. Furthermore, due to limitations in size and storage methods, the handling, assembly, and stowage of the platform are cumbersome, time-consuming, and labor-intensive, resulting in poor overall convenience.

[0004] Therefore, those skilled in the art have provided a portable ship maintenance support device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a portable ship maintenance support device to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A portable ship maintenance support device includes: a platform plate, a bottom frame fixedly mounted on the bottom of the platform plate by screws, a slide frame fixedly connected to the inner side of the bottom frame, a lifting frame rotatably mounted on the inner side of the slide frame, a stabilizing frame mounted below the lifting frame, a base frame fixedly mounted at both ends of the stabilizing frame, brake rollers mounted at both ends of the base frame, and a connecting arm mounted on the middle of the bottom frame through a long rod, with a bidirectional hydraulic cylinder mounted on the inner side of the end of the connecting arm connected to the long rod.

[0007] As a further embodiment of this utility model: one end of the connecting arm is fitted with a sliding structure to the long rod, and the connecting arm is rotatably connected to the bidirectional hydraulic cylinder.

[0008] As a further improvement of this utility model: a connecting rod is rotatably installed at the end of the connecting arm away from the long rod, and both ends of the connecting rod pass through one end of the lifting frame and are connected to the pulley.

[0009] As a further improvement of this utility model: the external shape of the lifting frame is an "X" structure, and the end of the lifting frame is movably connected to the slide rail frame.

[0010] As a further improvement of this utility model, the connecting rod is connected to the bidirectional hydraulic cylinder via a connecting arm.

[0011] As a further improvement of this utility model: an adjustment groove is fixedly provided on the surface of the stabilizing frame, and a drag rod is slidably installed inside the stabilizing frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The platform height can be adjusted by rotating and deforming the "X" structure lifting frame. There is no need to expand the overall area of ​​the platform. It can be adapted to the limited space of the ship's deck or cabin. After the platform is unfolded, different maintenance needs can be met by adjusting the height. It will not interfere with other equipment or structures of the ship due to its large size. Moreover, there are no complicated assembly steps. The lifting frame can be adjusted to adjust the height of the platform by driving the connecting arm and linkage through the two-way hydraulic cylinder. The whole process does not require tedious manual operation, saving time and labor costs. The platform can be moved by pulling out the towing rod inside the stabilizing frame and using the brake rollers on the underframe. There is no need to disassemble or move it. After maintenance, the platform can be pulled up and stored vertically. Compared with the traditional method of storing the platform flat, the vertical storage method greatly reduces the horizontal area occupied by the platform. This storage method can reduce the platform's occupation of the ship's storage space and effectively alleviate the contradiction of tight storage space for ship tools. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a portable ship maintenance support device, including: a platform plate 1, a bottom frame 4 fixedly installed at the bottom of the platform plate 1 by screws, a slide frame 5 fixedly connected to the inner side of the bottom frame 4, a lifting frame 6 rotatably installed on the inner side of the slide frame 5, a stabilizing frame 11 installed below the lifting frame 6, a base frame 2 fixedly installed at both ends of the stabilizing frame 11, brake rollers 3 installed at both ends of the base frame 2, an adjustment groove 13 fixedly opened on the surface of the stabilizing frame 11, and a towing rod 12 slidably installed inside the stabilizing frame 11; Specifically, the stabilizing frame 11 and the base frame 2 are fixed structures, forming the bottom stabilizing structure of the platform plate 1. The base frame 2 is equipped with brake rollers 3, which are mainly used for the overall movement of the platform plate 1. The braking structure is used to stop the movement. A towing rod 12 is slidably installed in the hollow structure inside the stabilizing frame 11. The towing rod 12 works with the adjustment groove 13 to achieve limited sliding. After the towing rod 12 is pulled out, the platform plate 1 is moved by using the towing rod 12 in conjunction with the brake rollers 3. The platform plate 1 is pulled upright. Compared with flat placement, vertical placement can save more storage space.

[0020] A connecting arm 8 is mounted on the middle of the base frame 4 via a long rod. A double-acting hydraulic cylinder 10 is mounted on the inner side of the end of the connecting arm 8 that is connected to the long rod. A sliding structure is fitted between one end of the connecting arm 8 and the long rod. The connecting arm 8 and the double-acting hydraulic cylinder 10 are rotatably connected. A connecting rod 7 is rotatably mounted on the end of the connecting arm 8 away from the long rod. Both ends of the connecting rod 7 pass through one end of the lifting frame 6 and are connected to the pulley 9. The external shape of the lifting frame 6 is an "X" structure, and the end of the lifting frame 6 is movably connected to the slide frame 5. The connecting rod 7 is connected to the double-acting hydraulic cylinder 10 through the connecting arm 8. Specifically, the two-way hydraulic cylinder 10 moves bidirectionally at both ends, pushing one end of the connecting arm 8 to slide along the long rod. The reciprocating sliding of the connecting arm 8 on the long rod will pull the connecting rod 7 to move. The movement of the connecting rod 7 will cause one end of the lifting frame 6 to slide along the slide rail frame 5 in conjunction with the pulley 9. The lifting frame 6 with the "X" structure has a sliding structure between one end and the slide rail frame 5 through the pulley 9, and a rotating structure between the other end and the slide rail frame 5. The height adjustment of the platform plate 1 is achieved by utilizing the rotational deformation of the "X" structure.

[0021] Working Principle: When using this invention, first place the platform plate 1 near the part of the ship that needs maintenance. If the height of the platform plate 1 needs to be adjusted, activate the bidirectional hydraulic cylinder 10. The two ends of the bidirectional hydraulic cylinder 10 move and pull, pushing one end of the connecting arm 8 to slide along the long rod. When the connecting arm 8 slides back and forth on the long rod, it will pull the connecting rod 7 to move. The movement of the connecting rod 7 will cause one end of the lifting frame 6 to slide along the slide rail frame 5 with the pulley 9. Since the lifting frame 6 has an "X" structure, one end is connected to the slide rail frame 5 through the pulley 9 to form a sliding structure, and the other end is connected to the slide rail frame 5 to form a rotating structure, utilizing the "X" structure. The rotational deformation of the structure enables the height adjustment of the platform plate 1 to meet maintenance needs at different heights. When the platform plate 1 needs to be moved, the pull rod 12 inside the stabilizing frame 11 is pulled out. The pull rod 12, in conjunction with the adjusting groove 13, achieves limited sliding. Through the pull rod 12 and the brake roller 3, the platform plate 1 can be dragged to move. After reaching the appropriate position, the brake structure is used to stop the brake roller 3, so that the platform plate 1 is stable in that position for maintenance work. After maintenance is completed, the platform plate 1 can be dragged upright to save storage space.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
