Description

Technical Field

[0001] The invention relates to the technical field of barge monitoring, and in particular to a device and a method for monitoring the horizontality of a barge during a process of being towed and launched into water. Background Art

[0002] With the application of the horizontal slipway construction method, pulling and launching has also become the main method for launching the construction products on the horizontal slipway. This method can ensure that the construction products are safely and effectively shifted to the semi-submersible barges and other ships with diving functions according to the established route, and then dive and separate to complete the launching operation. However, in the process of pulling and launching, the barge stage becomes the most risky link in the entire pulling and launching operation. Failure to barge indicates that the semi-submersible barge has failed to adjust the load. At the same time, the local force on the edge of the dock and the slideway increases sharply, and the towing operation is extremely difficult, which can easily cause the failure of the entire launching operation. Therefore, monitoring the horizontality of the barge becomes the key to barge, and even the key to the entire launching operation. The existing barge uses the total station to monitor the position of the reflector on the surface of the barge to judge the horizontality when conducting launching monitoring. However, when the existing reflector is installed, the reflector will produce relative displacement between the barge and the barge when the barge moves, which affects the monitoring results of the total station. If it is completely welded, it will increase the use of consumables and the cost is high. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a device and method for monitoring the horizontality of a barge during the process of being towed and launched into the water, which solves the above-mentioned problems.

[0010] As a further solution of the present invention: the bottom of the bracket is fixedly connected to an annular guide rail mounted around the connecting rod, the bottom of the annular guide rail is slidably connected to a sliding block, the bottom of the sliding block is fixedly connected to the top of the reflector, and through the arrangement of the sliding block and the annular guide rail, the supporting points of the reflector are increased, making it more stable and not prone to shaking.

[0011] A method for monitoring the horizontality of a barge during a towing and launching process comprises the following steps:

[0012] Step 1: Position the total station and select the installation position of the reflector on the barge;

[0013] Step 2. After the site selection is completed, first use the first welding rod to weld the mounting block to the surface of the barge, and then install the bracket, set the empty slot of the bracket above the mounting block, and then the protrusion of the mounting block enters the embedded slot. At this time, the bracket moves downward, driving the protrusion to be inserted into the embedded slot, and the bracket is placed. At this time, rotate the threaded rod to move to the left, drive the plug-in rod and the positioning rod to move to the left, drive the plug-in rod and the positioning rod to pass through the mounting block, and the positioning rod is inserted into the positioning slot of the inner cavity of the left placement slot. The plug-in rod is inserted into the plug-in slot in the mounting block. At this time, the bracket is installed, and then the second welding rod is used. The second welding groove and the top welding block are welded together by a welding rod to fix the bracket to prevent it from shaking relative to the bracket. Then, the connecting rod is leveled to adjust the angle of the reflector. After the reflector is adjusted, the third welding rod is inserted into the third welding groove to weld between the fixing block and the collar to fix the connecting rod to prevent it from shaking left and right during the subsequent movement of the barge, resulting in relative movement between the reflector and the barge. The third welding rod is set to be thin and light. When disassembling later, the fixing block and the collar can be separated by knocking, which is convenient for the next use.

[0014] Step 3: Monitor the reflectors through the total station. The monitored value changes will be transmitted to the central control room through the wireless signal of the wireless LAN for comparison with the subsequent monitored values; by comparing the value changes of multiple reflectors monitored, the ballast state of the barge and its horizontality with the dock are adjusted.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention can quickly install the reflective plate at any position and angle, and ensure that there is no shaking between the reflective plate and the barge while being able to install it quickly. The reflective plate is completely fixed by subsequent welding, and relative movement between the bracket and the mounting structure is effectively prevented. After use, the bracket and the mounting block can be quickly separated by knocking, and the bracket can be repeatedly used, reducing consumables.

[0017] The present invention performs welding between the fixing block and the collar to fix the connecting rod, thereby preventing the connecting rod from shaking left and right during the subsequent movement of the barge, resulting in relative movement between the reflector and the barge. In addition, the third welding rod is configured to be thin and light, so that the fixing block and the collar can be separated by only knocking during subsequent disassembly, which is convenient for next use.
