Problems solved by technology
[0003] 1) Steel strands are used as load-bearing cables for traction. When pulling, the steel strands are required to be in a straight line and cannot be turned. The salvage depth is limited by the width of the barge, and the lifting height must not exceed the width of the barge. Therefore, it is only suitable for rivers, lakes or shallow waters;
[0004] 2) During the salvage process of the sunken ship, the ship operating at sea will float up and down under the influence of sea waves, which brings great interference to the synchronous lifting operation of the sunken ship, and it is prone to excessive stress on a single steel cable, which is extremely Fragile devices, dangerous accidents

Embodiment 1
[0071] A chain traction device for salvage of sunken ships
[0072] Such as figure 1 , figure 2 As shown, the chain traction device includes: base 4, traction jack 7, front and rear push beams 6, 9, chain 3, front and rear clampers 5, 8, guide wheel assembly 13 and hydraulic pump station 15;
[0073] The base 4 includes a base platform 41, a guide rail 42 and a reaction force frame 43. The base platform is used as the base of other components of the chain traction device and is fixed on the deck of the barge 12. The guide rail 42 guides the push beam horizontal movement, and limit the up and down movement of the push beam, and the reaction frame is used as the support required for traction; the guide rail 42 and the reaction frame 43 are integrated with the base platform 41; (see figure 2 );
[0074] There is a cross opening on the front push beam 6 and the back push beam 9 (see Figure 4 ), for the chain 3 to pass through, and the front and rear push beams can slide on ...
Embodiment 2
[0082] A chain traction device used for salvage of sunken ships to realize the traction construction method of salvage of sunken ships
[0083] It is a traction construction method for sunken ship salvage using the chain traction device described in Embodiment 1 to realize sunken ship salvage; during traction construction, the chain passes through the front push beam 6, the rear push beam 9, and the guide block 11 , through the guide wheel 132 from the horizontal direction to the vertical direction to be connected with the sunken ship, the barge 12 pulls the chain with a constant tension of the winch 1, so that the chain 3 maintains a horizontal tension state; during the initial state of construction, the front clamp 5 and the rear The grippers 8 are all in the clamping state; its traction construction includes heavy object lifting operations and heavy object lowering operations, and its specific steps are:
[0084] A. Steps for lifting heavy objects:

Abstract
A chain traction device used for wreck salvage comprises a base, traction jacks, front and back pushing beams, a chain, front and back clamp holders, a guide wheel component and a hydraulic pump station. The device consists of two traction jacks symmetrically distributed side by side between the front and back pushing beams, the front and back clamp holders are connected to the front and back pushing beams, are the same in structure and comprise clamp blocks and clamp jacks, the clamp jacks are symmetrically distributed, the outer cylinder ends of the clamp jacks are fixed to the front and back pushing beams through pin shafts, piston rods are connected with the clamp blocks through pin shafts, the clamp blocks move up and down in a manner that cylinders are extended and contracted through the clamp jacks, to make the clamp blocks to be opened and closed, and thus the chain is clamped and loosened. According to the device, the chain is adopted to replace a steel strand for traction connection, flexible turning can be conducted, thus the salvage depth is not limited by the board width of a barge, and the deep sea salvage can be realized. The safety of the device and the salvage stationarity can be guaranteed through a wave compensation system.
Description
technical field [0001] The invention relates to a heavy object traction device and a traction construction method thereof, in particular to a chain type traction device for salvaging sunken ships and the traction construction method for realizing sunken ship salvage. Background technique [0002] The salvage of a sunken ship at sea requires multiple load-bearing cables to pull and lift the sunken ship. The patent publication number is CN101811563A, and the title of the invention is "A Salvage Method for a Sunken Ship at Sea". The sunken ship is lifted by force, which breaks through the traditional salvage process, and provides a salvage method that is different from the traditional craft, has a wide range of applications, high reliability, high safety, and fast speed. It is a new salvage method for sunken ship salvage technology. breakthrough; but this method also has the following deficiencies: [0003] 1) Steel strands are used as load-bearing cables for traction. When pu...
