Description

Technical Field

[0001] This utility model belongs to the field of hoisting equipment technology, specifically relating to an automatic hoisting device for ship hulls. Background Technology

[0002] A ship is a means of transportation that can navigate or anchor in waterways for transport or operations. It has different technical performance, equipment and structural forms according to different usage requirements. It is a man-made means of transportation that mainly operates in geographical waters and is well known to people.

[0003] When a ship's hull has been in use for a period of time or when problems arise, it needs to be hoisted up for easy repair and maintenance. However, the commonly used hoisting methods on the market are fixed rotating cranes, mobile rotating cranes, and gantry cranes. These types of hoisting equipment only meet the function of hoisting and are not conducive to personnel inspection. When personnel carry out inspections, they also need to use other lifting frames that are close to them. Therefore, it is necessary to optimize the structure of hoisting equipment. Utility Model Content

[0004] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide an automatic hull hoisting device.

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

[0006] An automatic hull hoisting device includes a basket frame, with lifting door mechanisms installed on both sides of the basket frame, two sets of limiting slide rail mechanisms slidably installed on the side of the basket frame, and a gantry crane mechanism installed on the top of the limiting slide rail mechanisms.

[0007] The lifting door mechanism includes a first motor and a transition wheel disposed on the upper side of the suspended basket frame. A first drum is installed at the output end of the first motor. A first steel wire rope is wound on the first drum. After passing through the transition wheel, the first steel wire rope is suspended and connected to a door frame. The door frame is slidably installed on the suspended basket frame.

[0008] The limiting slide rail mechanism includes a limiting frame fixedly installed on the side of the suspended basket frame. Each of the upper and lower sides of the limiting frame is provided with a set of rollers and a roller shaft. A limiting slide rail is slidably installed between the rollers and the roller shaft. A pressure roller with its output end in contact with the limiting slide rail is installed on the side of the limiting frame.

[0009] The overhead crane mechanism includes a base mounted on the top of the two limiting slide rails. The base is equipped with two second motors and two positioning wheels. The output ends of the two second motors are connected to a drive shaft. Second drums are mounted on both ends of the drive shaft. Second wire ropes are wound on the second drums. The ends of the second wire ropes are connected to the top of the suspended platform after passing through the positioning wheels. A coupling is installed between the drive shaft and the second motors. An encoder is connected to the drive shaft via a chain drive.

[0010] Furthermore, a liquid level sensor is installed at the bottom of the suspended platform. This design can determine the degree of water immersion of the suspended platform through electrical signal data, assisting in the start and stop of the entire hoisting equipment.

[0011] Furthermore, the limiting frame is equipped with a surface scraper and a set of side scrapers on each of its upper and lower sides. This design allows the surface scraper to clean the surface of the limiting slide rail during movement, while the side scrapers clean the two sides of the limiting slide rail during movement, ensuring that the sliding process is not interfered with by foreign objects, thereby ensuring the movement effect.

[0012] Furthermore, the base is equipped with a support roller, the upper side of which rolls in contact with the center of the drive shaft. This design, with the support roller supporting the center of the drive shaft, ensures the smooth operation of the drive shaft, reduces vibration and noise caused by eccentricity or imbalance, thereby improving the stability of the entire transmission system. The support at the center position can distribute the load on the drive shaft more evenly, avoid damage or wear caused by local overload, and extend the service life of the drive shaft.

[0013] Furthermore, the second drum is equipped with a rope presser. This design ensures that each wire rope is pressed firmly within the threaded groove of the second drum, preventing it from leaving the drum and reducing friction between them. This effectively extends the service life of the wire rope. Through the pressing action, the rope presser arranges the wire ropes on the second drum at fixed intervals, ensuring that they do not become tangled or twisted, maintaining the cleanliness and stability of the second drum, and facilitating its normal operation.

[0014] The beneficial effects of using this utility model are as follows:

[0015] This utility model is fully functional, not only capable of hoisting the hull for convenient maintenance, but also preventing the hull from being corroded by long-term immersion in seawater.

[0016] This utility model has a simple structure and is easy to operate. With further optimization of wireless transmission, it can realize the raising and lowering of the suspended basket frame by remote control, and can also remotely control the raising and lowering of the lifting door mechanism.

[0017] This utility model limits the lifting and lowering movement of the suspended basket frame through the effect of the limiting slide rail mechanism, ensuring stable and reliable operation.

[0018] The structural design of this utility model allows the hull to be hoisted as a whole on the gantry frame, and relevant personnel can directly perform maintenance and repairs on the hull from the gantry frame. It is simple and convenient. Moreover, the overall gantry crane mechanism has a simple and reasonable structure with few components, which is conducive to maintenance. Attached Figure Description

[0029] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figures 1-4As shown, the present invention provides an automatic hull hoisting device, which includes a basket frame 1, lifting door mechanisms 2 installed on both sides of the basket frame 1, two sets of limiting slide rail mechanisms 3 slidably installed on the side of the basket frame 1, and a gantry crane mechanism 4 installed on the top of the limiting slide rail mechanism 3.

[0031] The lifting door mechanism 2 includes a first motor 21 and a transition wheel 22 disposed on the upper side of the suspended basket frame 1. A first drum 23 is installed at the output end of the first motor 21. A first wire rope 24 is wound on the first drum 23. After passing through the transition wheel 22, the first wire rope 24 is suspended and connected to the door frame 25. The door frame 25 is slidably installed on the suspended basket frame 1.

[0032] The limiting slide rail mechanism 3 includes a limiting frame 31 fixedly installed on the side of the hanging basket frame 1. A set of rollers 32 and rollers 33 are provided on the upper and lower sides of the limiting frame 31. A limiting slide rail 34 is slidably installed between the rollers 32 and rollers 33. A pressure roller 35 with its output end in contact with the limiting slide rail 34 is installed on the side of the limiting frame 31.

[0033] The overhead crane mechanism 4 includes a base 41 mounted on top of two limit slide rails 34. The base 41 is equipped with two second motors 42 and two positioning wheels 43. The output ends of the two second motors 42 are connected to a drive shaft 44. Second drums 45 are mounted on both ends of the drive shaft 44. Second wire ropes 46 are wound on the second drums 45. The ends of the second wire ropes 46 are connected to the top of the suspended basket frame 1 after passing through the positioning wheels 43. A coupling 47 is installed between the drive shaft 44 and the second motors 42. An encoder 48 is connected to the drive shaft 44 via a chain drive.

[0034] In this implementation case, when using an automatic hull hoisting device, the lifting door mechanism 2 is opened, the hull moves into the hoisting basket 1, then the lifting door mechanism 2 is closed, the gantry crane 4 is operated, and the hoisting basket 1 is driven to rise smoothly under the limit of the limit slide rail mechanism 3, so that the hull leaves the water surface, achieving the purpose of water-free corrosion prevention and facilitating maintenance.

[0035] Specifically, the first motor 21 operates, driving the first drum 23 to wind the first wire rope 24. Under the rotation of the transition wheel 22, the gantry 25 is lifted, achieving the purpose of opening the lifting door mechanism 2. After the hull moves into place, the first motor 21 releases the wire, and the gantry 25 returns to its original position under its own weight, achieving the purpose of closing.

[0036] The gantry crane mechanism 4 operates in the following manner: two second motors 42 operate synchronously, and under the effect of the drive shaft 44, the two are also forced to synchronize. The rotation of the drive shaft 44 drives the second drum 45 to rotate, thereby winding the second wire rope 46 to achieve the purpose of lifting the suspended basket 1. During this process, the encoder 48 is used to memorize and provide feedback on the rising and falling positions of the suspended basket, which is conducive to moving to the required height.

[0037] Preferably, a liquid level sensor is installed at the bottom of the suspended platform 1. This design can determine the degree of water immersion of the suspended platform 1 through electrical signal data, and assist in starting and stopping the entire hoisting equipment. In fact, measures to identify whether the suspended platform 1 has been submerged in water can also be considered depending on the specific situation.

[0038] The preferred limiting frame 31 is equipped with a surface scraper 36 and a set of side scrapers 37 on each of its upper and lower sides. With this design, the surface scraper 36 can clean the surface of the limiting slide rail 34 during movement, and the side scrapers 37 can clean the two sides of the limiting slide rail 34 during movement, ensuring that it will not be interfered with by foreign objects during sliding, thereby ensuring the movement effect. In fact, measures to remove foreign objects and ensure the movement effect can also be considered according to specific circumstances.

[0039] Preferably, the base 41 is equipped with a roller 49, the upper side of which rolls in contact with the center of the drive shaft 44. This design, with the roller 49 supporting the center of the drive shaft 44, ensures the smooth operation of the drive shaft, reduces vibration and noise caused by eccentricity or imbalance, thereby improving the stability of the entire transmission system. The support at the center position can distribute the load on the drive shaft 44 more evenly, avoid damage or wear caused by local overload, and extend the service life of the drive shaft 44. In practice, the position and number of rollers 49 can also be considered according to specific circumstances.

[0040] Preferably, the second drum 45 is equipped with a rope presser 410. This design ensures that the second wire rope 46 is pressed down one by one in the threaded groove of the second drum 45, preventing the second wire rope 46 from leaving the second drum 45, thereby reducing mutual friction and effectively extending the service life of the second wire rope 46. Through the rope pressing action, the rope presser 410 arranges the second wire rope 46 on the second drum 45 with a fixed gap, ensuring that the rope is not tangled or twisted, maintaining the cleanliness and stability of the second drum 45, which is conducive to the normal operation of the second drum 45. In fact, the choice of rope pressing measures can also be considered according to specific circumstances.

[0041] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
