fig. 2 is a schematic structural view of the flagpole device of the present invention, which is a top view.
Detailed Description
The invention is further illustrated by the following specific examples:
the embodiment provides a first flagpole device of unrestrained cover is prevented to boats and ships, and this flagpole device makes flagpole 1 rise the operation process of flag convenient.
Referring to fig. 1 and 2, the flagpole apparatus of the present embodiment includes a flagpole 1, a flag-raising pulley assembly 21, a flag-lowering pulley assembly 22, a rope 3, and an operation hatch 4.
The flagpole 1 is a relatively common pulley flagpole, and as will be appreciated by those skilled in the art, a top pulley is provided on top of the pulley flagpole. The flagpole 1 of the present embodiment is further provided with a double pulley member provided at the lower portion of the flagpole 1. The double-pulley component is essentially formed by combining two fixed pulleys, and the two fixed pulleys respectively and independently operate.
The pulley assembly comprising the combination of the top pulley and the double pulley part provided on the flagpole 1 is called a rope guiding pulley block, that is, the flagpole 1 is provided with a rope guiding pulley block, and the rope guiding pulley block can guide the rope 3 to lift along the flagpole 1 with the flag.
The flagpole 1 is fixedly arranged at the forefront end part of the ship head wave-preventing cover 7, and the operation hatch 4 is arranged on the wave-preventing cover 7 and at a position far away from the flagpole 1.
The specific location of the arrangement of the access hatch 4 should follow the principle of "not interfering with the arrangement of the anchor moorings etc. on the deck and facilitating the addition of the vertical ladder 5".
A hatch cover is also arranged on the operation hatch 4 to prevent rainwater from entering in rainy days.
The rope 3 is provided with a mechanism for fixing the flag, specifically three circular ring buckles, the flag is provided with three corresponding round holes, and the three circular ring buckles on the rope 3 are respectively connected with the three round holes on the flag, so that the flag can be installed and fixed on the rope 3.
The rope 3 is also provided with a protruding limiting block which can be clamped at the top pulley at the top of the flagpole 1, and the protruding limiting block can smoothly pass through the pulleys at other pulleys, so that when the flag is lifted to the top of the flagpole 1, the protruding limiting block is just clamped at the pulley at the top of the flagpole 1, and the flag is prevented from being damaged due to the excessive lifting.
The flag-raising pulley assembly 21 and flag-lowering pulley assembly 22 are, in fact, a set of pulleys arranged along a determined path along which the rope 3 can be guided to travel. In the present embodiment, the sheave guide paths of both the flag-raising sheave assembly 21 and the flag-lowering sheave assembly 22 are parallel.
The flag-raising pulley assembly 21 and the flag-lowering pulley assembly 22 are both arranged on the wave-preventing cover 7 and extend from the operation hatch 4 to the flagpole 1.
The rope 3 is arranged on the rope guiding pulley block of the flag raising pulley combination 21, the flag lowering pulley combination 22 and the flagpole 1 in a penetrating way, specifically, the rope 3 is arranged in a penetrating way in sequence
Flag-raising pulley combination 21,
One pulley of the double pulley part of the rope guiding pulley block of the flagpole 1,
A top pulley in a rope guide pulley block of the flagpole 1,
The rope of the flagpole 1 is guided to the other pulley of the two pulley parts in the pulley block,
And a flag-lowering pulley assembly 22.
The ropes 3 are arranged in parallel and side by side on the wave shield 7.
In addition, still be provided with two knot rope rings 6 in operation hatch 4 department, the both ends of rope 3 also wear to establish simultaneously and pass through two knot rope rings 6, just so can make rope 3 be in the position department that is close to operation hatch 4 all the time, make things convenient for the operation of operating personnel. When the flag raising or lowering operation is completed, the rope 3 is fastened to the rope fastening ring 6, so that the rope 3 and the flag on the flagpole 1 can be positioned.
The operator can raise the flag to the flagpole 1 at the operation hatch 4, and can lower the flag on the flagpole 1 and recycle the flag to the operation hatch 4.
Specifically, when it is required to raise the flag at the flagpole 1, a crew installs the flag on the rope 3 at the flag-raising pulley assembly 21 at the operation hatch 4, then pulls the rope 3 at the flag-lowering pulley assembly 22, the rope 3 with the flag is moved to the flagpole 1 along the flag-raising pulley assembly 21, and is raised to the top of the flagpole 1, and then both ends of the rope 3 are fastened to the corresponding fastening rings 6. When the flag needs to be lowered from the flagpole 1, the rope 3 is pulled at the flag raising pulley combination 21, the rope 3 carries the flag to return to the operation hatch 4 along the flag raising pulley combination 21, the crew removes and recovers the flag from the rope 3, and then both ends of the rope 3 are fastened on the corresponding fastening rope rings 6.
In this embodiment, the flag raising pulley assembly 21 and the flag lowering pulley assembly 22 extend the rope 3 on the flagpole 1 to the operation hatch 4, so that a crew can conveniently raise or lower the flag on the flagpole 1 at the operation hatch 4, thereby facilitating the operation process and ensuring the safety of the crew.
Furthermore, a vertical ladder 5 is provided below the operation hatch 4, and the position where the vertical ladder 5 is provided follows the principle of "arrangement of the anchor mooring etc. on the deck is not hindered" and the vertical ladder 5 is facilitated.
The pulleys mentioned in this embodiment are fixed pulleys.
The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention, therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
