Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, in particular to a hatch cover safety hook hoisting tool. Background Art

[0002] The installation of hatch cover accessories is an important part of the ship construction process. It involves the stability and safety of the ship. When installing the hatch cover, the end stop device (safety hook) needs to be positioned on site. The traditional construction method is to hang the wire rope at a high place of the adjacent hatch cover and hang a manual hoist for lifting and positioning.

[0003] There are certain disadvantages in using traditional construction methods on site: First, when using traditional construction methods, because there is no aerial work platform, it is necessary to climb to a high place to hang the hoist, which makes it impossible to ensure the personal safety of workers; second, when using traditional construction methods, after hoisting to a high altitude, if there is no need to land temporarily, the hoist must be hung in the air, which causes the rope on the hoist to be damaged due to long-term hoisting of heavy objects, increasing the risk of casualties caused by the fall of heavy objects due to rope damage; third, the traditional construction method is to use manual hoists for construction. During hoisting, workers need to manually pull the ropes to lift the heavy objects. This method of hoisting consumes a lot of workers' strength. At the same time, because the manual hoist is hung only in an approximate position above the heavy object, in order to accurately drop the hook of the hoist near the heavy object, it requires workers to spend a lot of time and energy to adjust, which also increases the labor intensity of workers. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a hatch cover safety hook lifting tool, which is equipped with an aerial work platform and peripheral protection to ensure the safety of workers working at high altitudes, and the device is provided with an opening and closing door module. When lifting heavy objects to the aerial work platform, if it is not necessary to put it down immediately, the hoisted heavy objects can be placed on the opening and closing door module, so as to reduce the damage to the rope caused by long-term lifting of the heavy objects at high altitudes, thereby reducing the casualties caused by the heavy objects falling from high altitudes due to damage to the ropes, and the device is provided with a lifting module, which can accurately drop the hook near the heavy object through manual remote control, thereby saving the use of workers' strength and reducing the labor intensity of workers. The advantages solve the problems that there is no aerial work platform for workers during construction, the personal safety of workers is not guaranteed, the heavy objects are suspended in the air for a long time, which may damage the ropes and then cause casualties to the workers on the ground, and the lowering of the hoist requires manual operation, which is extremely laborious, and the inaccurate lowering of the hook requires the worker to slowly adjust, which increases the labor intensity of the workers.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a hatch cover safety hook hoisting tool, which has the following beneficial effects: 1. The hatch cover safety hook lifting tooling is equipped with a bottom plate, a protection module and a ladder. Through the coordinated use of these device structures, workers no longer need to climb up to a high altitude to hang a manual hoist for high-altitude operations when they need to lift. This effectively protects the personal safety of workers during construction. At the same time, because of the use of these device structures, workers can complete high-altitude operations more boldly, and to a certain extent, workers can be more assured when working at high altitudes.

[0016] 2. The hatch cover safety hook lifting tooling is provided with an opening and closing door module. The opening and closing door is opened or closed by the first motor of the opening and closing door module, so that the device does not need to put the heavy object to the specified position immediately when lifting the heavy object. When long-term suspension is required, the suspended heavy object can be temporarily placed on the opening and closing door, thereby temporarily unloading the lifting rope to reduce the damage to the rope caused by long-term lifting of the heavy object, and to a certain extent reducing the damage caused by long-term suspension of the rope to the heavy object, which makes the probability of heavy objects falling from a high altitude causing casualties on the ground.

[0017] 3. The hatch cover safety hook lifting tooling is equipped with a lifting module. Through the use of the lifting module, workers only need to use the laser position emitted by the laser indicator on the lifting module as a reference to fine-tune the lifting device so that the hook falls accurately near the heavy object to be lifted, thereby ensuring that the heavy object can be lifted smoothly to complete the work. This eliminates the need for workers to manually pull ropes for lifting, which undoubtedly reduces a lot of effort for workers. At the same time, the device also does not require workers to manually adjust the position of the lifting device, so this also reduces the labor intensity of workers to a certain extent.

Through the use of the lifting module 9, the workers only need to use the laser position emitted by the laser indicator 919 on the lifting module 9 as a reference to fine-tune the lifting device so that the hook 914 accurately falls near the heavy object to be lifted, thereby ensuring that the heavy object can be lifted smoothly to complete the work. This eliminates the need for workers to manually pull ropes for lifting, which undoubtedly reduces a lot of effort for the workers. At the same time, the device also does not require workers to manually adjust the position of the lifting device, so this also reduces the labor intensity of the workers to a certain extent.
