Description

Technical Field

[0001] This utility model relates to the field of ship repair technology, specifically to a hoisting device for ship repair. Background Technology

[0002] Gantry cranes are a type of bridge crane, also known as portal cranes. They are mainly used for loading and unloading cargo in outdoor freight yards and material yards. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility. They are widely used in ports. Their metal structure resembles a portal frame, with two legs installed under the main beam, allowing them to travel directly on ground tracks. The main beam can have cantilever beams extending outwards at both ends. As a type of lifting equipment, gantry cranes play an important role in ship repair. In current technology, gantry cranes are generally moved along the ground to the top of the ship to be repaired, and the slings are tightened to lift the ship for repair.

[0003] In the prior art, a ship repair hoisting device with publication number CN221971069U includes a hoisting frame, a hoisting module, and a clamping module. The hoisting module is fixedly installed on the hoisting frame and includes two hoisting mechanisms. Each hoisting mechanism includes a motor, the output end of which is provided with a winding spool. The winding spool is provided with a rope, one end of which is fixed to the winding spool, and the other end passes over a first pulley and a second pulley and connects to the clamping module. The clamping module includes a clamping base plate and a set of symmetrical clamps. The clamps are movably connected to the clamping base plate. Each clamp includes a clamping plate and a holding plate. The holding plate is hinged to the clamping plate. The clamping plate is provided with a tension spring, the two ends of which are respectively connected to the clamping plate and the holding plate. The holding plate is floatingly connected with a top rod. When hoisting through the clamping plate, the top rod can adjust the ship's repair posture and make clamping simple and quick, improving efficiency and safety.

[0004] However, while this type of lifting equipment can effectively perform lifting and maintenance operations on ships, the clamping and fixing position of the equipment to be repaired is relatively fixed during lifting. When it is necessary to fix and lift equipment with a wide width, it will cause uneven stress on the equipment. In addition, the synchronous limit on the front and rear sides of the equipment is not high when lifting the equipment to be repaired, which reduces the stability of equipment of different sizes under lifting.

[0005] Therefore, in view of this, we have studied and improved the existing structure to propose a hoisting equipment for ship repair. Utility Model Content

[0006] The purpose of this utility model is to provide a hoisting device for ship repair, so as to solve the problem mentioned in the background art that the clamping and fixing position of the equipment to be repaired is relatively fixed during hoisting, which will cause uneven force on the equipment when it is necessary to fix and hoist the equipment with a wide width.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for ship repair, comprising a main body, a hoisting cable roller rotatably connected to the inner wall of the main body, a hoisting cable wound around the outer wall of the hoisting cable roller, a hoisting frame fixedly connected to one end of the hoisting cable, a threaded slider slidably connected to the outer wall of the hoisting frame, a clamping rod detachably connected to the outer wall of the threaded slider, a support rod fixedly connected to the bottom of the clamping rod, a second servo motor provided on the outer wall of the clamping rod, a second threaded rod fixedly connected to the output end of the second servo motor, a lifting rod slidably connected to the outer wall of the second threaded rod, a rotating rod rotatably connected to the outer wall of the lifting rod, and a telescopic rod rotatably connected to the inner wall of the clamping rod at one end of the rotating rod.

[0008] Furthermore, a telescopic groove is provided at the connection between the inner wall of the clamping rod and the telescopic rod, and an electric push rod is provided on the outer wall of the telescopic rod, with a limit plate fixedly connected to one end of the electric push rod.

[0009] Furthermore, a first servo motor is provided on the top of the lifting frame, and a bevel gear set is fixedly connected to the output end of the first servo motor. A first threaded rod that is threadedly connected to the outer wall of the bevel gear set is fixedly connected to the outer wall of the threaded slider.

[0010] Furthermore, the first threaded rod is provided in two sets, and the two sets of the first threaded rod rotate in opposite directions.

[0011] Furthermore, the rotating rod forms a rotating structure through the lifting rod and the telescopic rod. There are two sets of rotating rods, and the positions of the two sets of rotating rods are symmetrically arranged about the central axis of the lifting rod.

[0012] Furthermore, the outer wall profile of the telescopic rod is L-shaped.

[0013] Furthermore, the limiting plate is symmetrically arranged about the central axis of the clamping rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, through the installation of a telescopic rod, improves the efficiency of adjusting and clamping equipment of different widths for transport during ship maintenance using hoisting equipment. It also enhances the uniformity of clamping force. Based on the required equipment width, a second servo motor is activated, rotating a second threaded rod to drive a lifting rod to slide along the outer wall of the clamping rod. This sliding motion of the lifting rod, through the rotation of a rotating rod, causes the telescopic rod to slide along the inner wall of the telescopic groove. This changes the clamping length of the clamping rod, and with the centering movement of the limiting plate, it applies a left-right clamping force to the equipment, preventing deviation and improving the stability of hoisting the maintenance equipment.

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.

[0024] Example 1:

[0025] like Figures 1-5As shown, a hoisting device for ship repair includes a main body 1. A hoisting cable roller 2 is rotatably connected to the inner wall of the main body 1. A hoisting cable 3 is wound around the outer wall of the hoisting cable roller 2. A hoisting frame 4 is fixedly connected to one end of the hoisting cable 3. A threaded slider 8 is slidably connected to the outer wall of the hoisting frame 4. A clamping rod 9 is detachably connected to the outer wall of the threaded slider 8. A support rod 10 is fixedly connected to the bottom of the clamping rod 9. A second servo motor 11 is provided on the outer wall of the clamping rod 9. A second threaded rod 12 is fixedly connected to the output end of the second servo motor 11. A lifting rod 13 is threadedly connected to the outer wall of the second threaded rod 12 and slidably connected to the outer wall of the clamping rod 9. A rotating rod 14 is rotatably connected to the outer wall of the lifting rod 13. A telescopic rod 15 is rotatably connected to the inner wall of the clamping rod 9 at one end of the rotating rod 14.

[0026] like Figure 5 As shown, a telescopic groove 16 is provided at the connection between the inner wall of the clamping rod 9 and the telescopic rod 15. An electric push rod 17 is provided on the outer wall of the telescopic rod 15. One end of the electric push rod 17 is fixedly connected to a limit plate 18, which facilitates the telescopic rod 15 to move conveniently through the opening of the telescopic groove 16.

[0027] like Figure 3 As shown, a first servo motor 5 is installed on the top of the lifting frame 4. A bevel gear set 6 is fixedly connected to the output end of the first servo motor 5. A first threaded rod 7, which is threaded to the outer wall of the bevel gear set 6, is fixedly connected to the outer wall of the threaded slider 8. This arrangement of the bevel gear set 6 and the first threaded rod 7 facilitates the relative sliding of the clamping rod 9.

[0028] like Figure 3 As shown, there are two sets of first threaded rods 7, and the two sets of first threaded rods 7 rotate in opposite directions. This is beneficial to the relative sliding of the clamping rod 9 by setting two sets of first threaded rods 7 with opposite rotation directions.

[0029] like Figure 5 As shown, the rotating rod 14 forms a rotating structure with the lifting rod 13 and the telescopic rod 15. There are two sets of rotating rods 14. The positions of the two sets of rotating rods 14 are symmetrically arranged about the central axis of the lifting rod 13, which facilitates the sliding of the lifting rod 13. Through the connection of the telescopic rod 15, the rotating rod 14 can be easily rotated, which can conveniently change the clamping width of the clamping rod 9.

[0030] like Figure 4 and Figure 5 As shown, the outer wall contour of the telescopic rod 15 is set in an L-shape, which is conducive to achieving the effect of convenient support for the bottom of the equipment to be maintained.

[0031] like Figure 4As shown, the limiting plate 18 is symmetrically arranged about the central axis of the clamping rod 9, which is beneficial to achieve the effect of synchronous limiting and fixing of the front and rear of the equipment to be repaired by the symmetrical arrangement of the limiting plate 18 about the central axis of the clamping rod 9.

[0032] Working principle: When using this type of ship repair hoisting equipment, in order to improve the effect of adjusting the clamping and transfer of equipment of different widths and improve the uniformity of the clamping force, according to the required width of the equipment, the second servo motor 11 is turned on. Through the rotation of the second threaded rod 12, the lifting rod 13 is driven to slide along the outer wall of the clamping rod 9. The sliding of the lifting rod 13, through the rotation of the rotating rod 14, drives the telescopic rod 15 to slide along the inner wall of the telescopic groove 16, so that the clamping length of the clamping rod 9 changes. Under the centering movement of the limiting plate 18, the equipment is clamped left and right, which plays a role in preventing the equipment from deviating and improving the stability of hoisting the repair equipment.

[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
