Examples
A high speed boat aluminum alloy balanced fast reverse mast as shown in fig. 1 to 5, comprising:
a fixed mast 2 which is fixed on the deck of the high-speed ship and used as a base, and a movable mast 1 which is arranged at the upper end of the fixed mast 2 and can rotate relatively;
the bottom of the movable mast 1 is rotatably connected with the top of the fixed mast 2;
the movable mast 1 and the fixed mast 2 are rotatably connected through an eye plate and a bolt;
the eye plates are divided into an upper eye plate 41 and a lower eye plate 42, the upper eye plate 41 is arranged on the movable mast 1 and fixedly connected with the front end of the bottom of the movable mast 1, the upper eye plate 41 is obliquely arranged downwards and forwards, the lower eye plate 42 is arranged on the fixed mast 2 and fixedly connected with the front end of the top of the fixed mast 2, the lower eye plate 42 is obliquely arranged upwards and forwards, the end parts of the foremost ends of the upper eye plate 41 and the lower eye plate 42 are intersected, and pin holes 43 are overlapped;
the upper eye plate 41 and the lower eye plate 42 are arranged in a V shape, the end parts of the upper eye plate and the lower eye plate are intersected, the arrangement mode ensures that the connection between the movable mast 1 and the fixed mast 2 is stable after the bolt is inserted into the pin hole 43 of the eye plate, when the movable mast 1 is turned forwards, the movable mast 1 is easily rotated and turned by taking the bolt as a rotation center when being subjected to an acting force for turning backwards when being installed in a conventional parallel eye plate matching mode, the arm of force is small, the rotation difficulty of the movable mast 1 is high, and the eye plates are arranged in a V shape, so that the eye plates are abutted to the bolt to generate an opposite acting force when the movable mast 1 is subjected to the acting force for turning backwards, the arm of force is increased, and the rotation of the movable mast 1 is convenient;
a cavity is arranged in the fixed mast 2, the upper end and the rear end of the cavity are opened, and the movable mast 1 extends downwards into the cavity to form a counterweight structure;
the mass ratio of the counterweight structure to the movable mast 1 is 1 (0.8-1.2), and the mass ratio of the counterweight structure to the movable mast is optimally controlled to be 1: 1;
through the arrangement of the counterweight structure, the gravity center of the movable mast 1 moves downwards, under the condition that the conventional movable mast 1 is not provided with the counterweight structure, as the mast is in a tapered shape, the whole gravity center of the movable mast 1 is positioned at a higher position and is far away from the hinged position of the movable mast 1 and the fixed mast 2, the movable mast 1 needs to be cooperated by multiple persons and has larger difficulty when being stably laid down or erected, and under the condition that the counterweight structure is arranged and the mass ratio of the counterweight structure to the movable mast 1 is 1:1, the whole gravity center formed by the movable mast 1 and the counterweight structure is positioned on the horizontal plane where the movable mast 1 and the fixed mast are connected, and within the mass ratio of 1 (0.8-1.2), the gravity center is positioned at the position basically, the fluctuation is smaller, the gravity center is closer to the hinged position of the movable mast 1 and the fixed mast 2, the moment arm is obviously reduced, so even if the whole, the stable placement and the standing can be more conveniently realized;
a pull-up handrail 5 which is convenient for a crew to operate to lay down or erect the movable mast 1 is arranged at the front end of the movable mast 1 at a proper height; the counterweight structure is composed of a counterweight chamber 3 and a counterweight block 31, the counterweight block 31 is arranged in the counterweight chamber 3, and includes but not limited to any one of the following two arrangement modes:
A. the counterweight block 31 is arranged at the bottom of the counterweight chamber 3 close to the front position, and the movement of the counterweight chamber is limited by virtue of a binding band and a bolt, so that the counterweight chamber is fixed, or structures such as a sealing plate 32 are arranged at the rear end of the counterweight chamber 3 for fixing, so that the gravity centers of the movable mast 1 and the counterweight structure are kept stable, and the movement is not found;
B. through set up fore-and-aft horizontal pole 33 in counter weight room 3, horizontal pole 33 surface sanding treatment, and 31 covers of balancing weight are established on horizontal pole 33, can follow horizontal pole 33 and slide from beginning to end, at least one end and 3 inside wall fixed connection in the front end of horizontal pole 33 and the rear end, and form the limit structure who prevents 31 slippage horizontal pole 33 of balancing weight, this mode of setting makes movable mast 1 and counterweight structure's whole focus can the back-and-forth movement to a certain extent, make things convenient for rising and steadily falling of movable mast 1 more, and can improve the stability that movable mast 1 stood.
