[0022] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0023] Example 1 See also Figure 1 As shown, the method for mounting the lashing bridge 101 provided in this application includes the following steps: Step S1, measuring the parameters of the lashing bridge 101; taking the top platform 102 of the lashing bridge 101 as the first reference position 103, measuring downwards to obtain a second reference position 104 at a theoretical height H from the top platform 102; Step S2, measuring the parameters of the installation position of the lashing bridge 101 on the main hull; respectively measuring the horizontal height X of the docking position of the plurality of guide posts 105 of the lashing bridge 101 on the bulkhead deck 106 of the main hull; n ; Step S3, determine the lower cutting position of the guide column 105; according to the horizontal height X of the docking position n , determine the upward cutting distance C of the corresponding guide column 105 n ; With the second reference position 104 as the reference, at a distance C from the second reference position 104 n Cut the corresponding guide column 105 at the position; Step S4: carry the lashing bridge 101 to the docking position.

[0024] In this embodiment, when measuring the parameters of the lashing bridge 101, the existing technology measures the height of each guide column 105 of the lashing bridge 101. Since the height of the lashing bridge 101 is relatively high and the number of guide columns 105 is relatively large, the measurement is difficult and labor-intensive, and it is difficult to ensure consistent measurement accuracy even after multiple measurements. In order to solve the above problems, the present application uses the height of the top platform 102 horizontally arranged on the lashing bridge 101 as a reference, and measures the position downward from the top platform 102 (i.e., the second reference position 104), so that the lower ends of multiple guide columns 105 of different lengths can be unified in height. Figure 2 and Figure 3 As shown in the figure, eight guide posts 105 are shown, and by setting the second reference position 104, the lower end heights of the eight guide posts 105 can be unified at one time.

[0025] When assembling the multiple guide posts 105 of the lashing bridge 101 with the main hull, the multiple guide posts 105 need to be docked one by one with the corresponding multiple docking positions on the bulkhead deck 106. Generally speaking, the horizontal heights of the multiple docking positions on the bulkhead deck 106 are different. When assembling the lashing bridge 101, it is necessary to cut margins on the guide posts 105 so that the multiple guide posts 105 can be coupled with the multiple docking positions at different heights. The horizontal heights X of different docking positions are measured on the same horizontal reference. n , thus correspondingly obtaining the distance C that the multiple guide posts 105 continue to cut upward based on the second reference position 104 n After the margins of the guide posts 105 are cut, the lashing bridge 101 is carried to the docking position, and multiple guide posts 105 can be precisely docked with the corresponding docking positions to ensure reliable and stable lap joints.

[0026] Compared with the existing method of carrying the lashing bridge 101, the method for carrying the lashing bridge 101 provided in the present application first undergoes accurate measurement, and then the lashing bridge 101 can be carried without any margin at one time. There is no need to waste time and effort in repeatedly carrying the lashing bridge 101 on board and repeatedly measuring it, which avoids the problem of difficulty in carrying due to the small working space on board, greatly speeds up the carrying efficiency, and avoids the deformation of the lashing bridge 101 during repeated carrying. In addition, the method steps for measuring and calculating the margin of this method are relatively simple and easy to operate, and there is no need to spend a lot of time on measurement and calculation, which can greatly speed up the overall process of carrying the lashing bridge 101.

[0027] In an optional solution of this embodiment, the upward cutting distance C of the guide column 105 is n The horizontal height X of the corresponding docking position n Equal. That is, when the horizontal height of the docking position is higher, the guide column 105 needs to be cut upward a greater distance; conversely, the distance is smaller. In this way, the multiple guide columns 105 of the lashing bridge 101 can be precisely docked with the corresponding docking positions, ensuring the reliability and stability of the lashing bridge 101.

[0028] In an optional solution of this embodiment, the lowest point among the multiple docking positions is used as a reference to calculate the horizontal heights X of the remaining docking positions. n ; The horizontal height of the docking position at the lowest point is 0, and the horizontal heights of the remaining docking positions are greater than or equal to 0.

[0029] In this embodiment, Figure 4As shown in the figure, 8 docking positions are shown, and the corresponding horizontal heights are X1, X2, X3, X4, X5, X6, X7, and X8, respectively. Taking the lowest point X2 as the reference, the horizontal heights X1, X3, X4, X5, X6, X7, and X8 of other docking positions are all positive values. In this way, when measuring the horizontal heights of multiple docking positions, the heights of the remaining docking positions are measured with the lowest docking position as the reference, which reduces the measurement difficulty, and the guide column 105 docked with the lowest docking position does not need to be cut, reducing the cutting workload.

[0030] In the optional solution of this embodiment, a pad 107 is provided at the docking position, and the horizontal height X of the docking position is n It is the horizontal height of the top surface of the pad 107. Specifically, the specifications of the pads 107 provided at each docking position are consistent, and the provision of the pads 107 can increase the strength of the docking position and further increase the reliability and stability of the overlap structure.

[0031] In the optional solution of this embodiment, the theoretical height H is the sum of the reference height H' of the guide column 105 of the lashing bridge 101 and the maximum cutting amount L of the guide column 105; the maximum cutting amount L of the guide column 105 is greater than or equal to the horizontal height X of the docking position. n The maximum value of .

[0032] In this embodiment, Figure 3 As shown, the portion H' located above the guide post 105 serves as the reference height for the guide post 105. This length must be set to meet the requirements for container mounting. A portion of the lower portion of the guide post 105 must be reserved for cutting. This portion, L's length, determines the maximum cutting depth of the guide post 105. Specifically, when cutting the guide post 105 upward from the second reference point 104, the cutting position cannot exceed this portion, ensuring that the cutting operation does not affect the securement of the guide post 105 to the container.

[0033] In an optional solution of this embodiment, specifically, the maximum cutting amount L of the guide column 105 is greater than or equal to 500 mm, so that the reserved size of the guide column 105 can meet the degree of ups and downs of multiple docking positions.

[0034] Example 2 The method for mounting the lashing bridge 101 in the second embodiment is an improvement on the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0035] In an optional solution of this embodiment, multiple first measuring points are set on the top platform 102 of the lashing bridge 101, and the theoretical height H from the top platform 102 is measured downward from the multiple measuring positions to obtain multiple second measuring points; the position of the second reference position 104 is obtained based on the multiple second measuring points.

[0036] In this embodiment, based on the principle that two points determine a line and three non-collinear points determine a plane, when determining the position of the second reference point 104, at least two first measuring points need to be set on the top platform 102 to measure the theoretical height H downward to obtain the corresponding second measuring points, thereby determining the precise position of the second reference point 104. The intersection of the second reference point 104 and the multiple guide columns 105 can determine the reference for the guide columns 105 to cut upward.

[0037] In an optional solution of this embodiment, the plurality of guide posts 105 of the lashing bridge 101 are arranged along a preset direction ( Figure 3 In the structure of the guide posts 105 arranged at intervals (direction A shown in FIG), that is, multiple guide posts 105 are arranged in a row, and multiple first measurement points set on the top platform 102 can be located in a preset direction, that is, multiple first measurement points are also arranged in a row along the same direction, and the corresponding second measurement points below the guide posts 105 are also arranged in a row along the same direction. The connecting line between the second measurement points can determine the reference for the guide posts 105 to cut upward.

[0038] In an optional solution of this embodiment, two first measurement points are specifically provided on the top platform 102 of the lashing bridge 101, each located at either end of a predetermined direction. The positions of the two second measurement points are determined by measuring the theoretical height H downward using a total station. A tension line is provided between the two second measurement points, such that the tension line intersects with the plurality of guide posts 105, thereby determining the bottom cutting reference of the guide posts 105. Alternatively, the tension line can be a physical line or a laser line generated by a level, both of which can determine the bottom cutting reference of the guide posts 105.
