Description

Technical Field

[0001] This utility model relates to an auxiliary docking device for assembling ship sections in a dry dock, and particularly to an auxiliary docking device for assembling ship sections in a dry dock applied in the field of shipbuilding. Background Technology

[0002] Currently, due to the length limitations of dry docks, large ships are often built in two or three sections, and then assembled in floating docks or off-site dry docks. When the hull sections are assembled in the dry dock, auxiliary docking devices are needed to facilitate the assembly and docking of the hull.

[0003] Chinese utility model patent CN201820779127.1 discloses an auxiliary device for hull section assembly, comprising: a positioning cylinder, a positioning pin inserted into a hole in the positioning cylinder, and a pin base installed on one side of the positioning pin. Several first reinforcing ribs are installed on the pin base; several second reinforcing ribs and a cylinder base are installed on the positioning cylinder. This utility model not only enables rapid assembly of hull sections, solving the deformation problem during the assembly process and ensuring the docking accuracy of the hull sections, but also greatly improves the assembly quality and efficiency of the hull sections.

[0004] When using the aforementioned device, since the positioning pin and the positioning cylinder are the same size, when assembling and connecting them using a floating crane or other hoisting methods, it is necessary to ensure that the positioning pin and the positioning cylinder are coaxial in order to successfully insert the positioning pin into the positioning cylinder. However, in actual hoisting, due to environmental influences, it is difficult to maintain stable coaxiality between the two for a long time. Therefore, it is necessary to try for a long time until the positioning pin is inserted into the positioning cylinder, which affects work efficiency. Moreover, the existing docking method mainly relies on the operator's visual observation, which has a large degree of subjectivity and error, making it difficult to guarantee the accuracy of docking, and has certain shortcomings. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is how to quickly dock the hull so as to facilitate the use of the assembled ship sections.

[0006] To address the aforementioned problems, this utility model provides an auxiliary docking device for assembling ship sections in a dry dock, comprising mounting base one and mounting base two.

[0007] Mounting base one is fixedly connected with a positioning pin, and mounting base two is provided with a positioning cylinder, the inner diameter of which is larger than the outer diameter of the positioning pin.

[0008] It also includes: multiple sets of telescopic cylinders, which are fixedly connected in a ring on the mounting base 2. Clamping rings are fixedly connected to the telescopic ends of the telescopic cylinders. Multiple sets of clamping rings are used to clamp and fix the positioning pins.

[0009] A mounting plate is fixedly connected to the end of mounting base two away from mounting base one, and a squeeze switch is fixedly connected inside the mounting plate.

[0010] A sliding plate is slidably connected to the mounting plate. The sliding plate is used to contact the positioning pin and generate pressing force on the squeeze switch.

[0011] In the auxiliary docking device for assembling ship sections in the aforementioned dry dock, the positioning pin is quickly inserted into the positioning cylinder, which effectively improves the work efficiency of assembling ship sections.

[0012] As a further improvement of this application, multiple sets of limiting holes are equally spaced on the positioning pin, and multiple sets of limiting rods are fixedly connected equally spaced on the inner ring of the clamping ring. The limiting rods are inserted into the limiting holes to fix the positioning pin.

[0013] As a further improvement to this application, a reinforcing rib is fixedly connected to the mounting base.

[0014] As a further improvement of this application, a groove is provided on the mounting plate, the squeeze switch is fixedly connected in the groove, and the sliding plate is slidably connected in the groove.

[0015] As another improvement of this application, a spring is fixedly connected inside the groove, and the other end of the spring is fixedly connected to the sliding plate.

[0016] As a further improvement to this application, the mounting base 2 is provided with a threaded hole, and a mounting rod is threadedly connected to the threaded hole. The mounting rod is rotatably connected to the mounting plate.

[0017] In summary, this device, by setting the inner diameter of the positioning cylinder to be larger than the outer diameter of the positioning pin, allows for the rapid insertion of the positioning pin into the positioning cylinder without requiring the two to be coaxial. Simultaneously, the telescopic cylinder drives the clamping ring to retract, locking and securing the positioning pin inside the positioning cylinder. By triggering the squeeze switch, the operator can determine whether the hull docking has been successful, reducing the uncertainty of visual observation, greatly improving the accuracy and reliability of docking, and effectively increasing work efficiency.

[0024] The following describes one embodiment of this application in detail with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-4 This invention illustrates an auxiliary docking device for assembling ship sections in a dry dock, comprising a mounting base 101 and a mounting base 201, and further comprising: a positioning pin 102 fixedly connected to the mounting base 101; a positioning cylinder 202 provided on the mounting base 201, the inner diameter of the positioning cylinder 202 being larger than the outer diameter of the positioning pin 102; multiple sets of telescopic cylinders 301, fixedly connected in a ring shape to the mounting base 201, with clamping rings 302 fixedly connected to the telescopic ends of the telescopic cylinders 301, the multiple sets of clamping rings 302 being used to clamp and fix the positioning pin 102; a mounting plate 401 fixedly connected to the end of the mounting base 201 away from the mounting base 101, a compression switch 403 fixedly connected inside the mounting plate 401; and a sliding plate 402 slidably connected to the mounting plate 401, the sliding plate 402 being used to... The positioning pin 102 contacts, generating pressing force on the squeeze switch 403; multiple sets of limiting holes 103 are equally spaced on the positioning pin 102, and multiple sets of limiting rods 303 are equally spaced and fixedly connected to the inner ring of the clamping ring 302. The limiting rods 303 are inserted into the limiting holes 103 to fix the positioning pin 102; a groove is provided on the mounting plate 401, the squeeze switch 403 is fixedly connected in the groove, the sliding plate 402 is slidably connected in the groove, a reinforcing rib plate 104 is fixedly connected on the mounting base 101, a spring 404 is fixedly connected in the groove, the other end of the spring 404 is fixedly connected to the sliding plate 402, a threaded hole is provided on the mounting base 201, and a mounting rod 405 is threadedly connected in the threaded hole. The mounting rod 405 is rotatably connected to the mounting plate 401.

[0027] Multiple clamping rings 302 can be spliced ​​together to form a circular ring, which is used to lock and fix the positioning pin 102.

[0028] When using this device, mounting base 101 and mounting base 201 are fixedly connected to the hull sections to be joined. Multiple sets can be installed to increase stability. Then, the hull is lifted and moved from one hull to another using a floating crane or other lifting method. Generally, the positioning pin 102 is moved. Since the inner diameter of the positioning cylinder 202 is larger than the diameter of the positioning pin 102 (but not too large, otherwise it will be difficult to clamp and fix the positioning pin 102 with the clamping ring 302 later; it only needs to be slightly larger to facilitate the subsequent insertion of the positioning pin 102, i.e., a certain margin is set, generally the ratio is 3:2), at this time, the positioning pin 102... 2. It can be easily inserted into the inner diameter of the positioning cylinder 202. Then, continue to lift and move the hull with the positioning pin 102 until the positioning pin 102 presses against the sliding plate 402, and then presses against the pressure switch 403. At this time, the pressure switch 403 sends a signal, and the movement can be stopped. Since the hull is heavy at this time, it has gravitational acceleration. At this time, it is necessary to wait for a few minutes until the hull stops moving and the pressure switch 403 continues to be pressed and sends a signal. This proves that the two sections of the hull have been fitted together. Alternatively, there can be no waiting. At this time, there needs to be a certain gap between the hulls to facilitate subsequent splicing. At this time, the mounting plate 401 can be removed. The specific selection depends on the requirements.

[0029] Then, the telescopic cylinder 301 can be activated, which drives the clamping ring 302 to move. Since multiple sets of docking devices are provided, when all the positioning pins 102 are inserted into the positioning cylinder 202, the positioning pins 102 are relatively close to the axis of the positioning cylinder 202. At this time, as the clamping ring 302 approaches, one or two sets will contact the positioning pins 102 as they move towards the axis, and then drive the positioning pins 102 to move until they reach the axis and fix the positioning pins 102. At the same time, the limiting rod 303 will be inserted into the limiting hole 103 to lock and fix the positioning pins 102, preventing the two from separating.

[0030] Then the two ends of the hull can be spliced ​​together. After the splicing is completed, the telescopic cylinder 301 can be reset and the clamping rings 302 can be moved away from each other. Then the mounting base 101 and mounting base 201 can be removed, or the mounting base 101 and mounting base 201 can be removed directly.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
