In general, a drillship is a vessel for extracting oil or gas from the ocean, and a vessel capable of drilling crude oil in a deep sea region or a sea with severe waves where it is impossible to install an offshore platform.

Such a drillship is a crude oil drilling ship having a function of extracting crude oil from deep seas by installing crude oil drilling equipment on the hull, and is one of advanced ships used for deep sea oil field development.

The drill ship is a high-tech ship, and is equipped with various advanced equipment such as a drill tower (pylon) that can install a pipe for deep drilling in the deep sea and oil refining equipment.

In this case, the drill pipe is coupled to the top driver installed in the main tower of the drillship and installed in the moon pool, and the top driver rotates the drill pipe to excavate the seabed.

Therefore, a work winch is installed in the door pool of the drillship to move or install various equipments, and an overload test is performed to ensure the safety of the winch.

Figure 1 shows a working diagram of a conventional winch overload test, the overload test is a normal test of the winch 100 using a main weight 200 of typically 10 tons (ton) After performing the test, the auxiliary weight 250 of 2.5 ton is added to the 10 ton for the 125% overload test.

However, when the 125% overload test is conventionally performed, since the winch 100 itself cannot lift 12.5 tons at the same time, a separate portable winch 400 is used. The 10 ton main weight 200 of 2,5 tons of additional weight 250 was loaded and tested.

Therefore, since a conventional portable winch must be installed and used for overload testing, test time is not only increased, but also workability is decreased, and work safety and process efficiency are also significantly reduced. There was a problem.

The present invention has been made to solve the above problems, an object of the present invention is to simply lift the auxiliary weight to be added to the main weight for the overload test of the winch by using a hydraulic or pneumatic cylinder It is an object of the present invention to provide a drillship A-type winch overload test apparatus that can improve operation convenience and work efficiency and ensure work safety.

In order to achieve the above object, the present invention provides a support having a predetermined area to support the bottom surface of the overload test auxiliary weight, and both ends of the support to be slidably coupled so that the support can move in the up and down directions. A main frame having a pair of slide shafts standing up and facing each other, an auxiliary support protruding from the slide shaft to support both ends of the support to be fixed at a specific height, and the main frame It is configured to include a plurality of lifting means installed on the elevating the support.

Here, a plurality of guide portions are respectively provided at both ends of the support, and a plurality of slide grooves are erected to correspond to the guide portion so that the guide portion is inserted and slides on the slide shaft.

On the other hand, the lifting means is composed of a plurality of hydraulic or pneumatic cylinders erected in the central portion of the main frame, it is preferable that a control valve for controlling the hydraulic or pneumatic cylinder is provided below the main frame.

In addition, the auxiliary support may be composed of a fixing plate protruding inwardly from the slide shaft so as to support both bottom surfaces of the support, and a reinforcing frame for reinforcing both ends of the fixing plate.

As described above, the present invention makes it easy to add the auxiliary weight to the main weight, thereby reducing the test time, thereby increasing productivity and improving the safety of the work, and the process of overload testing. Efficiency also has the effect of increasing.
