Technical Field

The invention relates to the field of water construction engineering, in particular to a water hoisting method for a large member.

Background

When a large-sized long-strip-shaped member is hoisted in a water area, two floating cranes are generally adopted to lift the member along two force application points in the length direction of the member, then the member is lifted through the matching of the two floating cranes, and then the member is moved to a corresponding position through the two floating cranes.

However, when the position, the horizontal direction, or the like of the member needs to be adjusted, the two floating cranes need to be moved correspondingly, so that the position, the horizontal direction, or the like of the member needs to be adjusted. However, the floating crane has a large volume, and needs to move a large distance when adjusting a member, and the two floating cranes are troublesome to match and need to be improved.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the method for hoisting the large member on water, which has the advantage that the position or the horizontal direction of the long-strip-shaped member is more conveniently adjusted.

In order to achieve the purpose, the invention provides the following technical scheme:

a method for hoisting a large-scale component on water comprises the following steps:

s1: the components are hoisted and connected, a floating crane is adopted, and two hooks on the floating crane are correspondingly hoisted to two sides of the gravity center position of the components along the length direction;

s2: the two ends of the member along the length direction are connected to different towing ships through ropes;

s3: hoisting and lifting the component, driving the component to move upwards by a crane of the floating crane, lifting the component to the hoisting height, and then moving the component to the hoisting position by the floating crane;

s4: and adjusting the position of the component, wherein the towing boat connected with the two ends of the component moves and pulls the component to adjust the horizontal direction of the component.

Through the technical scheme, after the member of large-scale rectangular shape hoists to corresponding the height, when needing to adjust member position or horizontal direction, the floating crane removes the position of member, and the towboat at both ends can drive the member and carry out the adjustment of horizontally horizontal direction simultaneously, and the removal of towboat is compared in the high efficiency that the floating crane can be more to make member position or horizontal direction adjustment convenient and fast more. In addition, the renting cost of the floating crane is higher and far higher than that of the towing ship, and the engineering expenditure can be saved by reducing the using number of the floating cranes.

Further, in S3, the component is hoisted to the hoisting height by the crane of the floating crane, then the floating crane drives the component to move toward the hoisting position, when the floating crane drives the component to move, the tow boats at the two ends of the component are used for tensioning the component, and the horizontal direction of the component is adjusted in the moving process of the floating crane.

Through the technical scheme, the floating crane drives the component to move, and meanwhile, the traction ships at the two ends can timely adjust the horizontal direction of the building in the component moving process, so that the integral hoisting is more efficient.

Furthermore, in S3, two tow boats are connected to each end of the member in the length direction, and the tow boats at each end of the member are respectively located at two sides of the member in the length direction.

Through above-mentioned technical scheme, every end all sets up two and pulls the ship, and when the horizontal direction of component needs to be adjusted, the pulling ship both sides at both ends are respectively, and every end all pulls through a pulling ship, and another pulling ship puts, makes the adjustment of horizontal direction more accurate convenient through the mode that receive and releases the combination.

Furthermore, in S2, the towing boat further comprises a towing machine, the towing machine comprises a turntable rotationally connected to the towing boat and a driving motor for driving the turntable to rotate, and the rope is wound on the turntable and connected with the towing boat.

Through above-mentioned technical scheme, the rope passes through the tractor and is connected with the traction ship, and when the rope initial stage was connected with the component, when the component lifted, the tractor was put the rope to reduced the rope and piled up the condition at the traction ship, also can reduce the condition that the rope was transferred into the surface of water and is corroded by water. In addition, when the component is adjusted horizontally by the towing boat, the power of the towing boat can be combined with the rope winding and unwinding of the rope, so that the adjustment response is quicker.

Furthermore, a mounting frame is arranged on the towing ship, and the towing machine is correspondingly arranged on the mounting frame; the mounting frame is connected with the towing ship through an elastic buffer piece.

Through above-mentioned technical scheme, the tractor passes through elastic buffer and is connected with the traction ship, and when the traction ship is at the traction in-process, receives the unrestrained formation of water and rocks, elastic buffer can form the cushioning effect, reduces the hull and rocks the condition that directly transmits to the mounting bracket to the influence of the upper and lower fluctuation of tractor to the component adjustment in the use has been reduced, thereby makes the hoist and mount of component more convenient.

Furthermore, the elastic buffer piece comprises a guide post fixedly connected to the traction ship, a guide sleeve fixed on the mounting frame and sleeved on the guide post in a sliding manner, and a buffer spring arranged in the guide sleeve and enabling the guide post and the guide sleeve to have a trend of being away from each other; the end part of the guide post, which is far away from the traction ship, is provided with a limiting part, and one end of the guide sleeve, which is close to the traction ship, is correspondingly provided with a limiting ring for limiting the guide post to be separated from the guide sleeve.

Through above-mentioned technical scheme, when ordinary state, guide post and uide bushing keep away from each other under buffer spring's elasticity, and spacing ring and spacing portion conflict each other this moment and form spacingly. When the wave comes, move the hull upward when the wave transmits to the hull, the wave is crossed the back hull and is reset, this in-process, when the hull shifts up, the mounting panel remains motionless earlier under inertial effect, and buffer spring can be compressed this moment for guide post and uide bushing are close to each other and slide, form buffering effect, thereby has reduced the wave and has once through the direct condition of rocking to the tractor on the mounting panel, makes integral hoisting more stable.

Furthermore, a ratchet wheel is coaxially fixed on the turntable, ratchets matched with the ratchet wheel for use are correspondingly hinged on the mounting plate, and the ratchets are abutted to the outer side wall of the ratchet wheel through abutting springs; when the rope is pulled to be rotated and released from the turntable, the ratchet teeth are used for limiting the rotation of the ratchet wheel so as to limit the release of the rope.

Through above-mentioned technical scheme, through the cooperation of ratchet for can enough drive the carousel through driving motor's rotation and receive the rope, can restrict again through ratchet's cooperation that the rope deviates from the carousel, reduce driving motor and continuously received the condition of torsion.

Further, when the ratchet is abutted against the ratchet wheel, the ratchet is obliquely and upwards arranged and abutted against the upper half part of the ratchet wheel, an abutting strip is further fixed on the traction ship and slides to penetrate through the mounting plate, and the abutting strip is used for abutting against the ratchet to enable the ratchet to be turned along the hinged part to be separated from the ratchet wheel.

Through the technical scheme, the component removes the in-process at the hoist and mount, when the wave of the surface of water is great, the whole focus of floating crane is lower, it can not be too strong to receive the wave influence, but the wave can be stronger to rocking that the traction ship formed when through the traction ship, the mount frame is great with the relative movement of traction ship under elastic buffer's effect this moment, the conflict strip can be contradicted to the ratchet under the relative movement of mounting bracket and traction ship this moment, and make ratchet and ratchet form brief breaking away from at the in-process of once contradicting, at this moment, the carousel can rotate and emit the surplus that the part formed and rocked with the rope, the influence to component position or horizontal direction has been rocked to stronger from top to bottom to the traction ship has been reduced, thereby make the hoist.

Compared with the prior art, the invention has the beneficial effects that:

(1) can drive the component through the traction ship and carry out the adjustment of horizontally horizontal direction, and the removal of traction ship compares in floating crane can be more high-efficient to make component position or horizontal direction adjustment convenient and fast more.
