Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting equipment safety technology, specifically a safety anti-detachment device for engine room lifting equipment. Background Technology
[0002] The main engine, non-standard cargo, and other items are inconvenient to handle inside the ship and require the ship's lifting equipment for hoisting. During hoisting, due to the ship's movement, there will be vibration and swaying in the engine room during navigation. The items on board will also have a certain swing amplitude when hoisted. There is an overhead crane in the engine room, and the engineer often uses the overhead crane with a lifting device to hoist heavy objects. However, if the hook is not equipped with a safety anti-detachment device when hoisting heavy objects, the heavy objects may swing in mid-air and detach from the hook, which is a dangerous situation.
[0003] Existing lifting safety anti-derailment devices can effectively prevent the ropes used to lift heavy objects from falling off the hanging structure. However, many of these devices are very difficult to unhook and limit the range of the ropes, making them inconvenient to remove when lifting thick ropes. Utility Model Content
[0004] The purpose of this utility model is to provide a safety anti-detachment device for engine room lifting gear, which solves the problems mentioned in the background art.
[0005] This application provides a safety anti-detachment device for a cabin spreader, including a fixed plate, a lifting lug fixedly connected to the top of the fixed plate, a limit fixing handle fixedly connected to the bottom of the fixed plate, a safety connecting handle fixedly connected to the bottom of the limit fixing handle, a hook fixedly connected to the bottom of the safety connecting handle, a safety anti-detachment component provided at the top of the safety connecting handle, and a limit component provided on one side of the hook.
[0006] By adopting the above technical solution, the lifting lugs facilitate the connection and fixation of the lifting equipment to the cabin, and the limiting and fixing handles facilitate the workers to hold and fix the load. The rope of the heavy object is hung on the hook, and then fixed and limited by the safety anti-derailment component and the limiting component to prevent the rope from falling off. At the same time, loading and unloading are very convenient.
[0007] Optionally, the safety anti-detachment component includes a U-shaped plate with through slots on both sides. Connecting side rods are provided on both sides of the U-shaped plate. A fixing screw is threaded through one side of each connecting side rod, and the tail end of the fixing screw extends through to one side of the other connecting side rod. The fixing screw passes through the through slot and is threadedly connected to the connecting side rod. A fixing nut is threadedly connected to the tail end of the fixing screw. A fixing clamp is provided on the inner side of both sets of connecting side rods and on the side away from the fixing screw, and the fixing clamp is fixedly connected to the connecting side rod.
[0008] By adopting the above technical solution, the U-shaped plate is connected to the connecting side rod by the fixed screw, and then fixed by the fixed nut, so that it will not loosen. The fixed screw is provided with a moving track by the through groove, and the fixed clamp is used to fix it in a certain part. One side of the U-shaped plate can be easily locked at the angle between the bottom of the safety connecting handle and one side of the hook.
[0009] Optionally, the limiting component includes a limiting block, which is fixedly connected to the hook. The bottom of the limiting block has a first anti-slip groove, and the bottom of the limiting block is in contact with the fixed lever.
[0010] By adopting the above technical solution, the angle formed by the set limit block and the hook is used to limit the fixed rod, and the first anti-slip groove is used to prevent the fixed rod from sliding, which ultimately leads to the loosening of one side of the safety anti-detachment component.
[0011] Optionally, a rubber sleeve is fitted onto the outer side of the fixing rod.
[0012] By adopting the above technical solution, the rubber sleeve increases the friction between the fixing rod and the limiting block, thus making the locking more stable.
[0013] Optionally, a second anti-slip groove is provided on the inner side of the U-shaped plate.
[0014] By adopting the above technical solution, the U-shaped plate will not easily slip when it is locked at the bottom of the safety connecting handle, making it more stable when locked.
[0015] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0016] This technical solution utilizes a fixed screw to connect the U-shaped plate to the connecting side rod, and then fixes it in place with a fixing nut to prevent loosening. A through groove provides a track for the fixed screw, and a fixing lever allows for easy locking at various points. One side of the U-shaped plate can be easily locked at the angle between the bottom of the safety connecting handle and one side of the hook, making loading and unloading very convenient. After lifting the U-shaped plate to the top of the safety connecting handle, moving it to the right will move the fixing lever to the right, thereby loosening the fixing lever. Lifting the connecting side rod allows for easy removal of the rope, and there is no restriction when loading and unloading thicker ropes. Attached Figure Description

[0022] Please see Figure 1-3 This utility model provides a technical solution: a safety anti-detachment device for a cabin hoist, including a fixed plate 1, a hoisting lug 12 fixedly connected to the top of the fixed plate 1, a limiting and fixing handle 2 fixedly connected to the bottom of the fixed plate 1, a safety connecting handle 3 fixedly connected to the bottom of the limiting and fixing handle 2, a hook 4 fixedly connected to the bottom of the safety connecting handle 3, a safety anti-detachment component provided at the top of the safety connecting handle 3, and a limiting component provided on one side of the hook 4;
[0023] In this technical solution, the lifting lug 12 facilitates the connection and fixation of the lifting equipment to the cabin, and the limiting and fixing handle 2 facilitates the worker's hand holding and fixing. The rope of the heavy object is hung on the hook 4, and then fixed and limited by the safety anti-derailment component and the limiting component to prevent the rope from falling off. At the same time, loading and unloading are very convenient.
[0024] In some technical solutions, such as Figures 1-3 The safety anti-detachment component includes a U-shaped plate 5. Through slots 51 are provided on both sides of the U-shaped plate 5. Connecting side rods 54 are provided on both sides of the U-shaped plate 5. A fixing screw 52 is threaded through one side of each connecting side rod 54. The tail end of the fixing screw 52 extends through to one side of the other connecting side rod 54, and the fixing screw 52 passes through the through slot 51. The fixing screw 52 is threadedly connected to the connecting side rod 54. A fixing nut 53 is threadedly connected to the tail end of the fixing screw 52, located inside the two sets of connecting side rods 54 and away from the fixing nut. A fixing rod 55 is provided on one side of the fixed screw 52, and the fixing rod 55 is fixedly connected to the connecting side rod 54. The U-shaped plate 5 is connected to the connecting side rod 54 by the fixing screw 52, and then fixed by the fixing nut 53 to prevent loosening. The through groove 51 provides a moving track for the fixing screw 52. The fixing rod 55 can be easily locked in a certain part for fixation. One side of the U-shaped plate 5 can be easily locked in the angle between the bottom of the safety connecting handle 3 and one side of the hook 4.
[0025] In some technical solutions, such as Figures 1-3 The limiting component includes a limiting block 6, which is fixedly connected to the hook 4. The bottom of the limiting block 6 is provided with a first anti-slip groove 61, and the bottom of the limiting block 6 is in contact with the fixed rod 55. The angle formed by the limiting block 6 and the hook 4 is used to limit the fixed rod 55, and the first anti-slip groove 61 is used to prevent the fixed rod 55 from sliding, which would eventually cause the safety anti-detachment component to loosen on one side.
[0026] In some technical solutions, such as Figures 1-3 A rubber sleeve is fitted on the outer side of the fixing rod 55; the rubber sleeve increases the friction between the fixing rod 55 and the limiting block 6, thus making it more stable.
[0027] In some technical solutions, such as Figures 1-3 The inner side of the U-shaped plate 5 is provided with a second anti-slip groove; this prevents the U-shaped plate 5 from easily sliding when it is locked at the bottom of the safety connecting handle 3, making it more stable when locked.
[0028] In use, after the telescopic hook is attached to the hook 4, the U-shaped plate 5, connecting side rod 54, and fixing rod 55 can be easily placed on the top of the hook 4 using the fixing screw 52 and fixing nut 53. Moving the U-shaped plate 5 to the right will allow the fixing rod 55 to move to the bottom of the limit block 6. After moving the U-shaped plate 5 to the right again and lowering it, it will be locked between the safety connecting handle 3 and the hook 4 diagonally, thus fixing the rope to the hook 4. After lifting the U-shaped plate 5 to the top of the safety connecting handle 3, moving it to the right will move the fixing rod 55 to the right, thus loosening the fixing rod 55. Lifting the connecting side rod 54 will allow the rope to be easily removed directly.
