Abstract
The utility model relates to deepwater drilling ships, in particular to a radar mast hydraulic folding device. A mast body fixed seat of the device is connected with a hinged plate, a rotatable radar mast body is connected with a hinged seat, and the hinged seat and the hinged plate are connected through a pin shaft. The lower end of a hydraulic cylinder is welded with a deck through an eye plate, and the upper end of the hydraulic cylinder is welded with the rotatable radar mast body through the eye plate. A hydraulic pump is connected with the hydraulic cylinder through a high pressure hose, and a throttling valve and a control handle are arranged on the hydraulic pump. The rotatable radar mast body is fastened and fixed with the mast body fixed base through a locking nut in the standing process, and the rotatable radar mast body is supported by a support welded on the deck in the laying down process. The radar mast hydraulic folding device can be laid down and avoid the probability that a helicopter collides with a mast, so that the safety of taking off and landing of the helicopter is guaranteed. The defect that an existing radar mast is in a non-folding fixing type, and the helicopter and the mast probably collide with each other is overcome.
Description
Technical field:
The utility model relates to a kind of deepwater drilling ship, particularly a kind of radar mast hydraulic foldable device.
Background technology:
At present, the radar mast of deepwater drilling ship on the highest top layer deck is all non-folding fixing pattern, because of radar mast and autogyro platform nearer, machine-made like this mast tends to affect hovering and the landing of autogyro, will cause fatal crass's accident in landing or the rotor that takes off with the scratching of radar mast phase once autogyro, this can cause considerable damage to lives and properties, and deepwater drilling ship can be taked to strengthen this backward way of distance between mast and helicopter platform and solve this problem at present.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of radar mast hydraulic foldable device, and this device has been realized and can have been fallen, the possibility of avoiding helicopter and mast to collide, the safety of guarantee autogyro landing.Having overcome existing radar mast is non-folding fixing pattern, the deficiency that helicopter and mast likely collide.
Technical solution adopted in the utility model is: a kind of radar mast hydraulic foldable device, comprises mast body firm banking, rotatable radar mast body and radar mast signal lamp; Connecting hinge carrier bar on mast body firm banking, on rotatable radar mast body, connect hinge seat, between hinge seat and flap, be connected by bearing pin, weld mutually by eye plate and deck hydraulic actuating cylinder lower end, weld mutually by eye plate and rotatable radar mast body hydraulic actuating cylinder upper end, Hydraulic Pump is connected with hydraulic actuating cylinder by high pressure hose, Hydraulic Pump is provided with flow regulating valve and bar handle, when rotatable radar mast body is stood, be locked by jam nut and mast body firm banking, when rotatable radar mast body fell, pass through welding supported above deck.
The beneficial effects of the utility model are: the utility model can fall, the possibility of avoiding helicopter and mast to collide, the safety of guarantee autogyro landing.
Brief description of the drawings:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is the structural representation of the utility model while falling.
Fig. 2 is that the A of Fig. 1 is to schematic diagram.
Fig. 3 is the structural representation of the utility model while standing.
Detailed description of the invention:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of radar mast hydraulic foldable device, comprises mast body firm banking 1, rotatable radar mast body 2 and radar mast signal lamp 8, connecting hinge carrier bar 11 on mast body firm banking 1, on rotatable radar mast body 2, connect hinge seat 10, between hinge seat 10 and flap 11, be connected by bearing pin 9, weld mutually by eye plate and deck hydraulic actuating cylinder 3 lower ends, weld mutually by eye plate and rotatable radar mast body 2 hydraulic actuating cylinder 3 upper ends, Hydraulic Pump 4 is connected with hydraulic actuating cylinder 3 by high pressure hose 5, Hydraulic Pump 4 is provided with flow regulating valve and bar handle 6, when standing, rotatable radar mast body 2 is locked by jam nut 12 and mast body firm banking 1, when falling, supported by welding support 7 above deck rotatable radar mast body 2.The piston rod of hydraulic actuating cylinder 3 is provided with anti-seawater water tight sheaths device, has ensured piston rod exposure portion in watertight chamber and has not been corroded.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
