DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-4As shown, a folding arm crane support device includes: a base 1, a plurality of telescopic frames 2 are fixedly connected to the top of the base 1, a first installation frame 3 is fixedly connected to the top of the telescopic frame 2, second installation frames 4 are arranged on both sides of the first installation frame 3, a fixed frame 5 is fixedly connected to the surface of the second installation frame 4, and two bolts 6 are threadedly connected to the inner wall of the fixed frame 5; a moisture-proof mechanism 7, which is arranged on one side of the fixed frame 5; wherein the moisture-proof mechanism 7 includes a protective frame 71 hinged to one side of the fixed frame 5, an airbag 73 is fixedly connected to the inner side of the protective frame 71, a sealing ring 72 is fixedly connected to one side of the fixed frame 5, and a moisture-proof component 74 is arranged on one side of the fixed frame 5.

[0026] When it is necessary to install the supporting device and the folding arm crane, the base 1 is fixed to the corresponding position on the offshore drilling platform by means of expansion screws, and the height of the telescopic frame 2 is adjusted and fixed by means of screws. At this time, the second mounting frame 4 is in contact with one side of the first mounting frame 3 and the fixed frame 5 is clamped on the telescopic frame 2. The bolt 6 is rotated so that the bolt 6 is threadedly connected in the fixed frame 5 and the telescopic frame 2, so that the second mounting frame 4 is fixed to the first mounting frame 3. At this time, the folding arm crane (the folding arm crane is a device with relatively mature application in the prior art, and the specific model can be selected according to actual needs and will not be elaborated here) is fixed to the first mounting frame 3 and the second mounting frame 4 by means of screws, and the folding arm crane can be used for operation.

[0027] After the bolts 6 are installed in the fixed frame 5 and the telescopic frame 2 , the protective frame 71 is pushed to contact the fixed frame 5 , so that the protective frame 71 covers and protects the bolts 6 to prevent water vapor from adhering to the bolts 6 .

[0028] like Figure 3-4 As shown, the moisture-proof component 74 includes an air storage tank 741 provided on the inner wall of the fixed frame 5, the inner wall of the air storage tank 741 is slidably connected with an air pusher frame 742, the inner wall of the air storage tank 741 is connected with a hose 743, the other end of the hose 743 is connected with the inner wall of the air bag 73, one side of the air pusher frame 742 is fixedly connected with a plurality of cone puncture needles 745, and the inner wall of the hose 743 is fixedly connected with a sealing film frame 744. Compressed gas is stored in the air storage tank 741. The sealing film on the sealing film frame 744 is a device with relatively mature application in the prior art, and the specific model can be selected according to actual needs, which will not be described in detail here.

[0029] When the protective frame 71 is covering and protecting the bolt 6, the protective frame 71 is flipped at an angle and pushes the air pusher frame 742 to move in the air storage tank 741. The air pusher frame 742 pushes the cone needle 745 to puncture the sealing film in the sealing film frame 744, so that the hose 743 is unobstructed. At this time, the air pusher frame 742 pushes the gas in the air storage tank 741 to be transported to the airbag 73 through the hose 743. The airbag 73 is filled with gas and stretches to contact the sealing ring 72, thereby sealing the contact between the protective frame 71 and the fixed frame 5.

[0030] like Figure 2 As shown, the inner wall of the fixed frame 5 is slidably connected with a fixed rod 748, the surface of the fixed rod 748 is clamped on the inner wall of the protective frame 71, one end of the fixed rod 748 is fixedly connected with a first spring 749, and the other end of the first spring 749 is fixedly connected to the inner wall of the fixed frame 5.

[0031] A protrusion is fixedly connected to one side of the protection frame 71, and a groove is opened on one side of the fixing frame 5. The area of ​​the groove is larger than the area of ​​the protrusion, and the surface of the fixing rod 748 is clamped on the inner wall of the protrusion.

[0032] The protection frame 71 abuts against one side of the fixed frame 5 . At this time, the elastic force of the first spring 749 pushes the fixed rod 748 to move and engage in the protection frame 71 , thereby positioning the protection frame 71 on the fixed frame 5 .

[0033] like Figure 3 As shown, one end of the bolt 6 is provided with a circularly distributed positioning hole 7410, the inner wall of the protective frame 71 is slidably connected with a positioning frame 746, one end of the positioning frame 746 is clamped on the inner wall of one side of the positioning hole 7410, one side of the positioning frame 746 is fixedly connected with a second spring 747, and the other end of the second spring 747 is fixedly connected to one side of the inner wall of the protective frame 71.

[0034] The elastic force of the second spring 747 pushes the positioning frame 746 to move and engage in the corresponding positioning hole 7410, thereby positioning the bolt 6.

[0035] When the locking cam 72 is in the unlocking state, the locking cam 72 is in the unlocking state, and the locking cam 72 is in the unlocking state, so that the locking cam 72 is locked and the locking cam 72 is locked.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
