Description

Technical Field

[0002] Ensuring the safe and reliable launching of large marine engineering products during slip launching has always been a difficult technical problem. Due to the limited length of the dock shoreline, when manufacturing marine engineering products, they are not directly placed on the dock front and loaded onto the ship, but are arranged in sequence from the dock front to the dock backcourt according to the launching time nodes. This results in the products on the dock backcourt often needing to slip a long distance, for example, more than 500 meters, during the process of slipping onto the ship. During such a long-distance traction, it is inevitable that the product will deviate due to asynchronous traction on the left and right sides, and there will be friction or jamming with the slideway baffle. At the same time, for heavier products, due to the large resistance, more traction mechanisms need to be equipped, and uneven force during traction by multiple traction mechanisms leads to slip deviation. In addition, during the slipping process, the initial angle of the dock shoreline and the non-uniform straightness of the dock slideway and the semi-submersible ship slideway are also not conducive to the slipping of marine engineering products.

[0049] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.

[0050] The structure and sliding scenario of the offshore sliding deviation correction device 410 according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0051] As Figure 1a 、 Figure 1b and Figure 3 shown in the general structure schematic diagram of the goods 100 being slid onto the ship, which includes a dock 200, a ship 300 (semi-submersible barge) and the goods 100. Among them, the sliding direction is from the dock 200 towards the direction where the ship 300 is located. Among them, a slideway 210 is provided on the dock 200, a slideway 310 is provided on the ship 300, and the offshore sliding deviation correction device 410 slides on the two slideways, driving the goods 100 to move from the dock 200 to the ship 300, completing the migration of the goods 100 from land to water. The above-mentioned sliding process requires a system composed of multiple offshore sliding deviation correction devices 410 to complete the entire sliding process. During the sliding process, when the goods 100 has a deviation angle during the sliding process, the deviation is corrected through the structure and connection relationship of the offshore sliding deviation correction device 410, so as to ensure that the goods 100 can quickly and smoothly move from the dock 200 to the ship 300.

[0052] The offshore sliding deviation correction device 410 according to the embodiments of the present invention will be described below first with reference to the accompanying drawings.

[0053] As Figures 2 to 8 shown, the offshore sliding deviation correction device 410 according to the embodiments of the present invention includes: being used for sliding on the slideways fixed on the dock 200 and the ship 300, including; a slide plate beam 414, a plurality of deviation correction wheels 412, at least one group of deviation correction stops 413, a traction and retraction mechanism, wherein the traction and retraction mechanism includes a pulley block 411, a steel wire rope 415, a guiding pulley 416 and a dynamometer 417. As Figure 2Schematic structural diagram of the traction mechanism shown. In this schematic diagram, it includes eight pulley blocks 411. Among them, every four pulley blocks 411 form a column, and the two columns of pulley blocks 411 are arranged symmetrically left and right. The four pulley blocks 411 in each column are connected in series by a steel wire rope 415. By connecting the pulley blocks 411 in series left and right, the multi-point divergent traction method in the prior art is simplified to left and right two-point traction, so that the traction force on each side is kept on a straight line, realizing multi-point synchronous traction. The steel wire ropes 415 at different traction points are subjected to the same force, effectively ensuring the safety during the traction process and preventing the occurrence of excessive force at a single point. When using the diagonal oblique pull of the steel wire rope 415 to correct the deviation, it is also easier to control.

[0054] A guide pulley 416 is provided on the steel wire rope 415 to change the rope outlet direction of the steel wire rope 415, facilitating the series connection of the rope-out steel wire ropes 415 on the two groups of pulleys. At the same time, a dynamometer 417 is also provided on the steel wire rope 415 to measure the tension of each group of series-connected steel wire ropes 415, ensuring that the traction forces on both sides are consistent. Uniform force application can effectively avoid the occurrence of skew phenomena, and during the traction process, it is beneficial to control the traction force not to exceed the maximum allowable value.

[0055] In addition, the traction and pulling-back mechanism of the present invention may include a traction mechanism and a pulling-back mechanism. When the goods 100 are severely skewed, the skew angle can be quickly and effectively corrected by diagonally pulling the pulley blocks 411 obliquely. For example, as Figure 2 shown, when skew occurs, the traction pulley and the pulling-back pulley steel wire ropes 415 can be connected in series in pairs on the left and right sides respectively, and the traction force is applied to the left front / right front side of the goods 100, and the pulling-back force is applied to the right rear / left rear side of the goods, so as to realize multi-point synchronous traction, ensure uniform force on the steel wire rope 415, and correct the attitude of the goods 100.

[0056] Specifically, the pulley block 411 is respectively connected between the cargo and the ship and between the cargo and the dock. The skateboard beam 414 is arranged opposite to the slideway, and the width of the skateboard beam 414 matches the width of the groove on the slideway, facilitating the sliding of the pulley block 411 in the groove of the slideway. Among them, the cargo 100 to be slid can be loaded on the skateboard beam 414. A plurality of alignment wheels 412 are respectively arranged at both ends of the skateboard beam 414 for sliding in the groove of the slideway. Each group of alignment blocks 413 includes two alignment blocks 413, and the two alignment blocks 413 are symmetrically arranged on the left and right sides of the skateboard beam 414 to limit the left and right swing of the skateboard beam 414. When skewing occurs, the alignment block 413 first frictions with the side wall 211 of the groove on the slideway and changes the skewing direction under the action of force. The alignment wheel 412 slides the skateboard beam 414 to the direction where the slideway is located under the action of thrust, thereby realizing alignment. One end of the steel wire rope 415 is connected to the pulley block 411, and the other end is connected to the traction mechanism and the pulling-back mechanism. The steel wire rope 415 is used to traction or pull back the cargo 100 to move along the direction of the slideway. The guiding pulley 416 is arranged on the steel wire rope 415 to limit the rope-out direction of the steel wire rope 415. The force measuring device 417 is installed on the steel wire rope 415 to monitor the force condition of the steel wire rope 415.

[0057] According to the offshore sliding alignment device 410 of the embodiment of the present invention, it can be reused, is easy to maintain, has low later maintenance cost, has a simple structure, and can always correct the skew condition of the cargo 100 during the process of sliding the cargo 100, avoiding large skew, thereby improving the sliding speed.

[0058] As Figure 3 shown in the position layout of the alignment device sliding device, where it can be seen from A upwards that the structure of multiple columns of offshore sliding alignment devices respectively installed with multiple columns of slideways can be adopted, for example, 3 columns, to ensure the smoothness of sliding. The bottom of the alignment device is embedded in the groove of the slideway, facilitating the left and right limit during the sliding process.

[0059] As Figure 4 and Figure 5 shown, alignment wheels 412 are provided on the skateboard beam 414. Among them, the alignment wheels 412 are respectively arranged at the head end and the tail end of the skateboard beam 414. The installation structure of the alignment wheel 412 at the head end is exemplarily shown in this schematic diagram. Alignment blocks are symmetrically arranged on both sides of the skateboard beam 414. As Figure 6 and Figure 7 shown, the alignment wheels 412 and the alignment blocks are arranged in the groove of the slideway, and the alignment blocks correspond to the side wall 211 of the groove. When skewing occurs, the alignment blocks can correct the sliding direction of the device through the reaction force during the collision with the side wall 211 of the groove.

[0060] According to an embodiment of the present application, as Figure 8As shown, the deviation correction wheel 412 is a roller structure. The deviation correction wheel 412 includes a connection seat 412a, an ear plate 412c, and a guide wheel 412d. The connection seat 412a is fixedly connected to the skateboard beam 414. One end of the ear plate 412c is fixedly connected to the connection seat 412a through a connection plate 412b. An installation hole is provided on the ear plate 412c, and the guide wheel 412d is fixedly mounted on the ear plate 412c by cooperating with the installation hole through a pin shaft 412e. This structure is simple, can roll flexibly, and is convenient for sliding.

[0061] According to an embodiment of the present application, one side of the deviation correction block facing the groove side wall 211 of the slideway is a smooth arc-shaped structure. This structure can reduce the collision friction force between the groove side wall 211 and the deviation correction block, which is more conducive to deviation correction.

[0062] The present application also discloses an offshore sliding deviation correction system, which includes the above-mentioned Figures 2 - 8 described offshore sliding deviation correction device 410, steel fender 420, and adjusting shim (not shown). Among them, the specific structure and working principle of the offshore sliding deviation correction device have been described in detail in the above embodiments. For details, reference can be made to the Figures 2 to 8 description of the above embodiments, which will not be elaborated here.

[0063] As Figure 9 shown, the steel fender 420 is used to fix the slideways on the dock 200 and the slideways on the ship 300, and is used to limit the swing of the two slideways. The adjusting shim is arranged on the steel fender 420. During the sliding process, when the straightness of the slideways on the dock 200 and the ship is inconsistent after being laid, or when the dock 200 has an initial angle resulting in inconsistent straightness of the slideways, by changing the thickness of the rigid berthing between the dock 200 and the semi-submersible barge, the initial angle of the dock 200 can be conveniently eliminated, and the straightness of the slideways on the dock 200 and the ship 300 can be kept consistent.

[0064] The offshore sliding deviation correction system 400 according to the embodiment of the present application can effectively correct the deviation of the cargo 100, which is convenient for controlling the site and reduces the difficulty of deviation correction. The present invention also discloses a deviation correction method for offshore sliding, which is applied to the above-mentioned Figure 2 and Figure 9 shown offshore sliding deviation correction system 400. The method includes: placing the cargo 100 to be slid on multiple rows of skateboard beams 414, and the deviation correction device 410 group slides the sliding cargo 100 from the dock 200 towards the ship 300 under the traction of the traction mechanism, and the traction mechanism performs multi-point series traction on the cargo 100 through the steel wire rope 415.

[0065] When, during the sliding process, the sliding cargo 100 has a first deviation angle within a preset range, the first deviation angle is corrected through the cooperation of the deviation correction wheel 412 and the deviation correction block. For example, a deviation of 3 degrees means the included angle formed between the moving route of the sliding cargo 100 and the slideway.

[0066] When, during the sliding process, the second skew angle of the sliding cargo 100 exceeds the preset range, for example, 5 degrees, and the diagonal traction steel wire rope 415 is used to correct the skew, the second skew angle, where the second skew angle is greater than the first skew angle. This angle can be set according to the actual situation and is not limited here.

[0067] When the initial angle of the dock 200 and / or the straightness of the slideway on the dock 200 and the slideway on the ship 300 exceed the set requirements, adjustment is made through the steel fender 420 and the adjusting shim so that the straightness of the slideway on the dock 200 and the slideway on the ship 300 remains within the set requirements.

[0068] In an embodiment of the present application, when, during the sliding process, the second skew angle of the sliding cargo 100 exceeds the preset range, the traction system uses the diagonal traction steel wire rope 415, measures the force on the steel wire rope 415 through the dynamometer 417, and adjusts the uniform force on the pulley block 411 according to the magnitude of the force on the steel wire rope 415 to correct the skew.

[0069] In an embodiment of the present application, the traction mechanism uses the diagonal traction steel wire rope 415, including: applying a traction force to the left front / right front of the cargo 100, applying a pulling-back force to the right rear / left rear direction of the cargo 100 through the pulling-back mechanism, and stopping applying the traction force and the pulling-back force to the right front / left front and left rear / right rear directions of the cargo 100. Thus, the skew of the cargo 100 is corrected.

[0070] During the description of the above-mentioned offshore sliding skew correction system 400 and offshore sliding skew correction device 410, their working processes and principles are described. Therefore, the specific implementation process of this method can refer to the Figures 2 to 8 description of the structure in the above embodiments and will not be elaborated here.

[0071] According to the offshore sliding skew correction method of the embodiments of the present invention, multi-point synchronous traction is achieved, which facilitates on-site control, reduces the difficulty of skew correction, and can be adjusted when the dock 200 shoreline has an initial angle or the straightness of the dock 200 slideway and the ship slideway is inconsistent. The adjustment is simple and convenient.
