Embodiment 1

[0033] in such as figure 1 image 3In the shown embodiment 1, a tower mast automatic lifting device, the tower mast 1 is rotatably arranged on the mast base frame 2 of the ship, the mast base frame is a U-shaped structure with the opening facing upward, the base A horizontal shaft 3 perpendicular to the direction of navigation of the ship is provided on the frame, and the lower part of the mast is hinged to the horizontal shaft. meshing, a reduction gear 7 is provided on the wheel shaft of the intermediate gear, a fixed gear 8 coaxial with the horizontal axis is provided on the mast base frame, the reduction gear meshes with the fixed gear, and a counterweight is provided at the end of the mast below the horizontal axis 9. There is also a hand wheel 10 on the wheel shaft of the intermediate gear. When the mast motor rotates, the driving gear drives the reduction gear to rotate through the intermediate gear, and the mast rotates relative to the horizontal axis and the fixed ge...

Embodiment 2

[0042] The swing mechanism of embodiment 2 (see Figure 4 ) includes a swing motor (not shown in the figure), the swing motor is a speed-regulating motor, the power shaft 21 of the swing motor is stacked with a forward drive gear 22 and a reverse drive gear 23, the forward drive gear and the reverse drive gear The drive gears are all sector gears with the same number of teeth and are arranged in a misplaced position. The swing mechanism also includes a swing gear 24, the forward drive gear is intermittently meshed with the swing gear, the reverse drive gear is intermittently meshed with the reversing gear 25, and the reversing gear is in contact with the reversing gear. The swing gear meshes, and the swing gear meshes with the swing output gear 27 through a reduction transmission gear 26. When the forward drive gear meshes with the swing gear, the reverse drive gear disengages with the reversing gear, and when the reverse drive gear meshes with the reversing gear , the forward...

Embodiment 3

[0045] The mast top of embodiment 3 is provided with emergency anti-collision mechanism (see Figure 5 ), the emergency anti-collision mechanism includes a straight rod 28 and a compression spring 29, the length direction of the straight rod is parallel to the length direction of the ship, the straight rod is slidably worn on the mast, and the front end of the straight rod is provided with a bumper , the compression spring is sleeved on the straight rod, one end of the compression spring is in contact with the impact head, the other end is in contact with the mast, the rear end of the straight rod is provided with a limit plate 31 to prevent the straight rod from coming out, the limit plate The end of the straight rod on the rear side is fixed with a stay cord 32, and the stay cord is connected with the draw ring through a pulley mechanism 33. The obstacle detection device of this embodiment is arranged below the straight rod; a clutch is provided between the driving gear and ...

Abstract

The invention discloses an automatic lifting device and method for a tower-shaped mast. A mast base frame is provided with a horizontal shaft, and the lower portion of the mast is hinged to the horizontal shaft. A mast motor on the mast is meshed with a speed reduction gear through a driving gear and an intermediate gear. The mast base frame is provided with a fixing gear coaxial with the horizontal shaft. The speed reduction gear is meshed with the fixing gear. A balance block is arranged at the position, below the horizontal shaft, of the tail end of the mast. Swinging type barrier detection devices are arranged on two sides of the top of the mast respectively. The automatic lifting device for the tower-shaped mast further comprises a control device and an alarm device. The control device is connected with the mast motor, the barrier detection device and the alarm device. The automatic lifting device and method for the tower-shaped mast resolve the problem that mast in the prior art are prone to being crashed due to negligence or misjudgment. The automatic lifting device for the tower-shaped mast can automatically detect barriers and put down the mast so as to guarantee navigation safety, and has high practical value.

Description

technical field [0001] The invention relates to the technical field of marine mast lifting, in particular to a tower-shaped automatic mast lifting device and a mast lifting method that can effectively prevent collisions between ship masts and obstacles such as bridges. Background technique [0002] Masts are generally installed on the centerline of the highest ceiling of the ship, and are used to install radar, navigation signal lights and communication antennas, etc., and are very important safety facilities when the ship is sailing. The structure of the mast usually has a single column type, a tower type, etc. When a ship passes under a bridge erected on the water, if the mast on the ship may collide with the bridge, it is necessary to lower (or put down) the mast in advance, and the ship can pass safely after lowering the height. The mast lowering process in the prior art needs to manually determine in advance whether there are obstacles such as bridges ahead and the wat...
