Each upper short shaft and each lower short shaft are respectively sleeved with at least two bearing adding jackets, the jackets play a role in protecting the bearings inside from being eroded by dust and facilitating welding of the connecting plates, the connecting plates for the front, rear, upper and lower short shafts adjacent to the middle long shaft are used for drawing and connecting two ends outside the long shaft travelling wheel and the bearing adding jackets on the short shafts into a whole, and each jacket of the bearing adding jackets is only drawn and connected with a single connecting plate so as to facilitate rotation. Pulleys are respectively sleeved on the upper short shafts on the left side and the right side, the upper pressure frame is pressed on the pulleys in a left-right mode, forks are arranged on the left and the right sides of the front top head of the pressure frame to buckle the pulleys on the upper short shaft arranged at the foremost position of the lower side, return stay wires are hung at the rear end of the pressure frame, counterweights are hung at the other ends of the return stay wires changing directions by means of turning pulleys to enable the pressure frame and a push rod to retreat and return after acting, a pressure rod taking a fulcrum, namely a rotating point, as a boundary is divided into a front end and a rear end, a resistance arm is arranged at the front end and a power arm is arranged at the rear end, the power arm is used for applying pressure on the lower pressure pulley to apply work and is used for balancing after acting or in a reverse situation, the pressure pulley mounted in the middle section on the upper side of the pressure frame is attached to the upper pressure rod power arm on the upper side, the pull wires are hung at the top head of the power arm and connected with the upper end of the, or a suspender with the top head capable of swinging back and forth is directly hung on the top head of which the pressure lever is close to the power arm. The top of the lower end of the suspender is provided with a travelling wheel which is attached to the boss or the bottom surface of the ship body (when no deviation exists), and the front edge of the travelling wheel (divided into front and back along the forward pushing direction of the push rod) is a positioning block for preventing the travelling wheel from moving forward. Such devices are installed in opposite phases to each other, at least one of front-back or left-right, or front-back and left-right, respectively, on the hull.

The working principle and the working process are as follows: when the ship body is in correct position, the top of the lower end of the suspender is attached to the platform surface of the boss or the bottom surface of the ship body, the weight of the suspender falls on the platform surface or the bottom surface of the ship body below the suspender, and when the upper end of the ship body deviates forwards (rightwards), the suspender does not work because the travelling wheel of the top of the lower end is blocked by the right positioning block; when the ship body deviates to the back (left), the top of the upper end of the suspender is connected with the rotating wheel which can rotate in situ and can rotate left and right, so that the lower end of the suspender moves left to be always vertical and is separated from the table top to be in a suspension shape, the pull line and the pressure rod are pulled left and downward, or the pressure rod is pulled downward by the gravity formed by the suspension rod which is suspended on the power arm of the pressure rod and the top of the upper end of the suspender can swing left and right to press the pressure-bearing pulley, so that the pressure-bearing pulley and the pressure frame apply pressure to the front, back, left and right upper short shafts on the lower side, because the weight of the counterweight suspended by the return pull line is limited, the pulling force is far smaller than the gravity of the suspender or the pulling force formed in the suspension, so that the descending and the ascending of all the upper short shafts on the long and short shaft combined push rod are carried out simultaneously until the upper short shafts and the, when the pressure bar is folded, the center distances of the upper short shaft and the lower short shaft which are bounded by the middle long shaft can be equal or different, when the upper short shaft is longer than the lower short shaft, the descending size of the upper short shaft and the descending size of the pressure pulley are correspondingly increased, otherwise, the descending size is correspondingly reduced, the height of the pressure rail is lower at the back and higher at the front and is not horizontal, so that the descending size is completely offset or offset, the descending size of the upper short shaft and the ascending size of the travelling wheel on the middle long shaft positioned at the forefront along the pressure rail are equal (descending and ascending are carried out simultaneously), and the pressure bar is horizontal; the balance is offset, the pressure rod is low at the back and high at the front (divided into front and back by the pushing trend), the pressure and the thrust are formed at the low front at the back (the thrust is reduced by the pressure and increased by the thrust), therefore, the pressure rod does not need to swing in the process of applying pressure to the pressed pulley and only compresses tightly, when the pull-line pull-pressure rod is selected, the pull-line pull-pressure rod only needs to be tensioned without being pulled down, the lower end of the pull line is tied and hung at the top head of the upper end of the suspender and is very close to a rotating point (the center of a rotating wheel connected with the top head of the upper end. The compression sheave and the pressure frame move forward with the push rod and act to increase the weight of the front (right) side of the vessel to offset the offset even if it is back balanced in a small amount of offset.

In order to increase the pressure on the front edge, a counterweight is sleeved on the middle long shaft at the forefront. In order to prevent the pressure of the pressure lever from being reduced in the process of pressurizing the pressure-bearing pulleys, a forward pressure lever and a backward pressure lever are selected, each pressure lever power arm is respectively attached to the left pressure-bearing pulley and the right pressure-bearing pulley below the pressure lever, one pressure-bearing pulley is far away from a pressure lever fulcrum, and the other pressure-bearing pulley is far away from the pressure lever fulcrum in the pushing process. The device is respectively provided with at least one of the left side, the right side, the front end and the rear end on the same ship, the opposite side is arranged in a reverse direction, in the process of shifting the ship body, one of the two opposite devices does not move along with the shifting of the ship body, and the other device plays a balancing role. When the ship body is restored to be balanced, the gravity of the suspension rod is born by the plane of the boss or the bottom surface of the ship body, and at the moment, because the pressure of the pressure lever is no longer present, the push rod and the pressure frame which are moved forward to the right position are pulled back to be reset by the pulling force formed by the return pull wire which is tied at the rear end of the pressure frame and the balance weight which is hung at the other end of the return pull wire.

In order to increase the pushing size of the combined push rod of the long and short shafts under the condition that the original size of the combined push rod of the long and short shafts is not changed, pulleys are additionally arranged on the left and the right of a middle long shaft on the back edge, an annular groove on the outer edge of each pulley is attached to an inverted cone-shaped push plate with a wide upper part and a narrow lower part on the back edge, single rows (two left and right rows) or multiple rows of inverted cone-shaped push plates are arranged in a front-back and inner-back flat mode, a travelling wheel is arranged in the front-back of the top head of the upper end of each row of inverted cone-shaped push plates and loosely clamps the annular groove on the outer edge of the travelling wheel by an upper-lower flat rail, the upper and the lower parts on the two sides of a flat rail support are respectively attached to a vertical rail, a return pull wire is hung on the upper edge of the flat rail support, the direction of the return pull wire is changed downwards by a turning pulley, a counterweight is hung on the top head at the lower end of the, the lower end of one row of (central) inverted cone-shaped push plates extends downwards, the top of the lower end of the inverted cone-shaped push plates is provided with a pulley positioned between a left plate and a right plate, the peripheral upper edge of the sliding wheel flange is attached to a flat-mounted triangle (the adjacent edge is on, the opposite edge is in front, and the inclined edge is under) which can move forwards and backwards and the lower edge of the sliding wheel flange is low in front and high in back, the rear ends of the conical press plates and the back edge of an upper pressure frame are provided with the same stay wire which changes directions by means of a turning pulley to be mutually connected, the front and the back of the upper edge of the flat-mounted conical press plates are respectively provided with travelling wheels in a hanging shape, namely, the travelling wheels can. Others are unchanged.

The working process and working principle are as follows: when the ship body deviates, the top of the suspender is connected with the rotating wheel which can rotate in situ and can rotate back and forth, so that the lower end of the suspender moves backwards and always keeps vertical, and is separated from the platform surface to form a hanging shape to form gravity, the pull wire and the pressure rod are pulled downwards to apply pressure to the pressed pulley, or the pressure rod is directly pulled downwards by the gravity formed by the suspender which is hung on the pressure rod power arm and can swing back and forth in a hanging shape to apply pressure to the pressed pulley and the pressure frame to the front, back, left and right upper short shafts on the lower side, so that the descending of all the upper short shafts and the ascending of the lower short shafts on the long and short shaft combined push rod are simultaneously carried out until the upper short shafts and the middle long shaft are in the same straight line and pushed forwards, and simultaneously the pressure frame pulls the flat conical pressure plate on the lower side backwards by the tail end pull wire in the forward movement along with the push rod, and the lower side of the flat conical pressure plate is a slope with high front and low back (, the inverted cone-shaped push plates are connected with the liftable upper and lower flat track supports in the backward movement process and are pressed downwards to descend, and the long and short shaft combined push rods are pushed forwards in the descending process, so that the forward displacement size of the push rods is increased.

Each upper short shaft and each lower short shaft are sleeved with two bearing adding outer sleeves 7 which are blocked by nuts 9 to prevent loosening, the outer sleeves play a role in protecting the bearings in the upper short shafts and the lower short shafts from being eroded by dust and facilitating welding of the connecting plates 6, the connecting plates 6 are used for the front short shaft, the rear short shaft, the upper short shaft and the lower short shaft which are adjacent to the middle long shaft 4 to draw the two ends outside the long shaft travelling wheel and the outer sleeves of the bearing adding outer sleeves 7 on the short shafts into a whole, and the outer sleeves of each bearing adding outer sleeve are only drawn with a single connecting plate to facilitate rotation. Pulleys 10 are respectively sleeved on the upper short shafts on the left side and the right side, an upper pressure frame 16 is pressed on the pulleys 10 from left to right (only the right side is shown in the figure), a return pull wire 18 is tied at the rear end of the pressure frame, a counterweight 19 is hung at the other end of the return pull wire and used for connecting the pressure frame after acting and retreating and returning a push rod, a pressed pulley 14 is installed in the middle section of the upper side of the pressure frame and is attached to one end of an upper pressure rod, namely a power arm 15, and a positioning baffle 25 is arranged behind the pressure frame and the push rod. The pressure lever with the pivot point 13 as the boundary is divided into the front end and the rear end, the rear end is the resistance arm 12, the front end is the power arm 15, the power arm is used for applying pressure on the pressed pulley at the lower edge to do work, the resistance arm is used for balancing after the work is done, the top of the power arm 15 is hung with a pull wire 26 which is connected with the top of the upper end of a suspender 21 at the lower edge by changing the direction through a turning pulley 24, the top of the upper end of the suspender 21 is connected with a rotating wheel 20 into a whole and can swing back and forth, the top of the lower end of the suspender is provided with a travelling wheel 22 which is attached to a boss 55 at the lower edge, and the front edge of the travelling wheel (divided into the front and the. Such devices are installed in opposite phases to each other, at least one of front-back or left-right, or front-back and left-right, respectively, on the hull.

The working principle and the working process are as follows: when the end of the ship body 11 is right, the top of the lower end of the suspender 21 is attached to the table surface of the boss 55, namely the weight of the suspender falls on the table surface below the suspender, and when the upper end of the ship body deviates to the right (front), the suspender 21 does not work because the top of the lower end is blocked by the right positioning baffle 23; when the ship body deviates to the left (rear), because the top head at the upper end of the suspension rod 21 is connected with the rotating wheel 20 which can rotate in situ and can rotate left and right, the lower end of the suspension rod can always keep vertical when moving to the left, thus the suspension rod is separated from the table top to be in a vertical suspension shape, unless being pulled by the pull wire 26 to be in a near vertical shape, but the work is not influenced, therefore, the pull wire 26 and the pressure rod power arm are pulled downwards to apply pressure on the pressed pulley 14, the pressed pulley 14 and the pressure frame 16 are enabled to apply pressure on the front, the rear, the left and the right upper short shafts 3 at the lower side, because the weight 19 suspended at the lower end of the return pull wire 18 is limited, namely the pulling force of the return pull wire 18 is far smaller than that of the pull wire 26, the descending of all the upper short shafts 3 and the ascending of the lower short shafts 5 on the long and short shaft combined push rod are simultaneously carried out until being in the same straight line with the, therefore, the descending size of the upper short shaft is offset for a part or all of the descending size or the rest of the descending size, and the offset part slightly swings downwards in the pressure lever power arm in the working process; the descending size of the upper short shaft and the ascending size of the travelling wheel on the forefront middle long shaft moving forwards along the clamping rail are completely offset (descending and ascending are carried out simultaneously), and the pressure lever is horizontal; the rest is offset, the pressure lever is low at the back and high at the front (divided into front and back by the pushing trend), the pressure and the pushing force are formed at the back and high at the front (the pressure is reduced and the pushing force is increased), when the pressure lever does not need to swing to apply the pressure, the lower end of the stay wire 26 is hung at the top head close to the upper end of the suspender, the pulling force is larger, namely only the stay wire is tensioned, and the pulling force is larger by means of the force of the labor-saving lever. The compression sheave and the pressure frame move forward with the push rod and act to increase the weight of the front edge of the boat to counteract the misalignment, even if it quickly regains balance in a small amount of misalignment.

To increase the pressure on the anterior side, a weight 60 is sleeved over the anterior-most one of the long medial axes. The device is respectively provided with at least one of the left side, the right side, the front end and the rear end on the same ship, the opposite side is arranged in a reverse direction, in the process of shifting the ship body, one of the two opposite devices does not move along with the shifting of the ship body, and the other device plays a balancing role. When the ship body is restored to balance, the suspension rod of the ship body restores to the balance, the gravity of the suspension rod is borne by the boss platform, and at the moment, the push rod and the pressure frame which are moved forward are pulled back to restore by the pulling force formed by the return pull wire and the return pull wire 18 which are tied at the rear end of the pressure frame and the suspended counterweight 19 until the push rod and the pressure frame are blocked by the positioning block 25 because the pressure rod loses pressure.
