Embodiment 1

[0035] in such as figure 1 In the shown embodiment 1, a cylindrical mast anti-collision device, the cylindrical mast 34 is rotatably arranged on the mast base frame 35 of the ship, the mast base frame is a U-shaped structure with the opening facing upwards, the The base frame is provided with a horizontal rotating shaft 1 perpendicular to the ship's navigation direction, and a sliding sleeve 2 for positioning the mast is fixed in the middle of the horizontal rotating shaft. A rack 3 is arranged, and the outer wall of the sliding sleeve is provided with a mast motor 4 and a support 36 for fixing the gear transmission system (see Figure 4 ), the output shaft of the mast motor is provided with a mast drive gear 5, the mast drive gear meshes with a mast lifting gear 6, and a gap 7 is provided on the side wall corresponding to the sliding sleeve and the rack (see image 3 ), one side of the mast lifting gear meshes with the rack on the mast through the gap on the side wall of the...

Embodiment 2

[0044] The swing mechanism of embodiment 2 (see Figure 6 ) 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 driving gears are sector gears with the same number of teeth and the same modulus and are arranged in dislocation. The swing mechanism also includes a swing gear 24. The forward drive gear is intermittently meshed with the swing gear, and the reverse drive gear is intermittently meshed with the reversing gear 25. The gear is engaged with the swing gear, and the swing gear is engaged with the swing output gear 27 through a reduction transmission gear 26. When the forward drive gear is engaged with the swing gear, the reverse drive gear is disengaged from the reversing gear, and the reverse drive gear is engaged with the reversing gear. When the gears are engaged, the ...

Embodiment 3

[0047] The mast top of embodiment 3 is provided with emergency anti-collision mechanism (see Figure 7 ), 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 mast motor and th...

Abstract

The invention discloses an anti-collision device and method for a column-shaped mast. A horizontal rotating shaft is arranged on a mast base frame; a sliding sleeve is fixed to the middle of the horizontal rotating shaft; the mast is arranged in a sliding sleeve in a penetrating manner, and a tooth bar is arranged on the outer wall of the lower half part of the mast in the axial direction; a mast motor is meshed with the tooth bar through a mast driving gear and a mast lifting gear; a fixed gear which is coaxial with the horizontal rotating shaft is arranged on the mast base frame; the mast lifting gear is meshed with the fixed gear through a deceleration gear set; a swinging barrier detector is arranged on the mast base frame. The anti-collision device for the column-shaped mast further comprises a control device and an alarm device, wherein the control device is connected with the mast motor, the barrier detector and the alarm device. The automatic anti-collision device effectively solves the problem that a conventional mast lifter is liable to cause collision accidents due to neglect or wrong judgment. The automatic anti-collision device for the column-shaped mast, which is disclosed by the invention, can automatically detect barriers and can automatically put down the mast, so that the sailing can be guaranteed safe; the automatic anti-collision device has a high practical value.

Description

technical field [0001] The invention relates to the technical field of marine mast lifting, in particular to a cylindrical mast anti-collision device and a mast anti-collision 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 ...
