Description

Technical Field

[0001] The utility model relates to the technical field of underwater operation, in particular to a watertight barrel tooling for a dock door lower winch seat. Background Art

[0002] Most existing dry docks in shipyards use pneumatic lying dock doors. Since the dock door's lower capstan is immersed in seawater all year round and is impacted by the opening and closing of the dock door, as the service life reaches the design life, the dock door's lower capstan will inevitably experience severe corrosion, loose bolts, elongated studs, etc., and it needs to be repaired in time to ensure the normal operation of the dock door's lower capstan.

[0003] At present, repairing the lower capstan of the dock gate usually requires divers to dive underwater for work. Underwater, the use of auxiliary tools such as electric and pneumatic tools is limited, and the strength of welding cannot be guaranteed. For this reason, it is usually necessary to build a temporary cofferdam outside the dock gate before repair to isolate the entire dock gate and dry dock from the seawater, and then drain the water in the temporary cofferdam to expose the entire lower capstan. After that, the lower capstan can be repaired in a waterless state. When the work is completed, the temporary cofferdam is removed.

[0004] However, since the dry dock is usually designed to be hundreds of meters wide, building a temporary cofferdam is not only costly but also time-consuming, making it difficult to implement. In addition, since the maintenance range of the lower capstan is small, if a temporary cofferdam is built, all dock gates need to be fenced off, which will affect the normal operation of the shipyard and have a low cost-effectiveness.

[0026] The following is a further detailed description of the watertight cylinder tooling for the lower capstan seat of the dock door proposed by the utility model in combination with the accompanying drawings and specific embodiments. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. In addition, the structure shown in the accompanying drawings is often a part of the actual structure. In particular, the emphasis that needs to be shown in each accompanying drawing is different, and sometimes different proportions are used.

[0027] It should be noted that the "first", "second" and the like in the specification, claims and drawings of the utility model are used to distinguish similar objects in order to describe the embodiments of the utility model, and are not used to describe a specific order or sequence. It should be understood that the structures used in this way can be interchanged under appropriate circumstances. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] This embodiment provides a dock door lower capstan watertight tube tooling, such as Figures 1 to 4 As shown, it includes: a cylinder 110, the top and bottom of the cylinder 110 have openings, and the opening at the bottom is used to accommodate the lower capstan 200 of the dock; a fastening device 120, which is arranged on the outside of the side wall of the cylinder 110 and is used to connect and fix the cylinder 110 to the side wall of the dock; a water pump assembly 130, including a water pump 131 and a pipeline 132, and the water pump assembly 130 is configured as follows: the water pump 131 pumps out the water in the cylinder 110 and discharges it to the outside of the cylinder 110 through the pipeline 132.

[0029] The dock gate lower capstan watertight cylinder tooling provided in the present embodiment can separate the dock gate lower capstan from seawater through the cylinder body 110 when the construction enclosure range is minimized, and can pump out the water in the cylinder body 110 by utilizing the water pump assembly 130, thereby ensuring that the dock gate lower capstan is always in a waterless environment during maintenance. Since the volume of the cylinder body 110 is relatively small, the construction cost and cycle are low, thus not only reducing the maintenance cost but also ensuring the maintenance effect, thereby solving the problem of high maintenance cost and low efficiency of the existing dock gate lower capstan.

[0030] In actual application, the material of the cylinder 110 should be waterproof and have certain pressure resistance and corrosion resistance, so that when the cylinder 110 is immersed in seawater, the cylinder 110 will not be deformed due to the seawater pressure, or corroded by seawater due to long-term use, thereby ensuring the safety of personnel inside the cylinder 110 when repairing the winch seat under the dock door.

[0031] Furthermore, in this embodiment, if Figure 2As shown, a sealing ring 140 is provided at the edge of the bottom opening of the cylinder 110. Since the bottom of the cylinder 110 has an opening, in order to prevent seawater from penetrating into the cylinder 110 from the contact surface between the bottom of the cylinder 110 and the lower capstan seat 200 of the dock gate, a sealing ring 140 is added to the bottom opening of the cylinder 110 in this embodiment. Thanks to the elastic texture of the sealing ring 140, it can be ensured that the bottom opening of the cylinder 110 and the contact surface of the lower capstan seat 200 of the dock gate have good sealing performance, thereby achieving waterproof sealing. And when the cylinder 110 is lowered, the sealing ring 140 can also play a buffering role, ensuring that the bottom of the cylinder 110 will not collide with the lower capstan seat 200 of the dock gate, thereby ensuring the service life of the lower capstan seat watertight cylinder tooling of the dock gate and the equipment status of the lower capstan seat of the dock gate.

[0032] Preferably, in this embodiment, the sealing ring 140 is a Q-type sealing ring. Figure 3 As shown, the annular portion of the Q-shaped sealing ring 141 is located at the bottom, and is used to contact the platform of the lower winch seat 200 of the dock door, and the straight portion is fixed to the bottom opening of the cylinder 110 by bolts 142. Thanks to the annular portion of the Q-shaped sealing ring 141, the sealing ring has good elasticity and pressure resistance, and is suitable for waterproofing in underwater operations.

[0033] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, the fastening device 120 includes at least two fastening plates located on the top of the cylinder 110. Specifically, the fastening device 120 is arranged close to the dock surface and can be fixed to the top of the cylinder 110 and the dock surface by riveting or welding, so that the cylinder 110 is fixed to the dock surface. In order to ensure the stability of the fixation, multiple fastening plates can be used to fix different positions of the cylinder 110 to the dock surface, so that the winch seat under the dock door can still be repaired in the case of waves.

[0034] Furthermore, in this embodiment, if Figure 2 As shown, the water pump 131 is arranged at the bottom of the cylinder 110 and is connected to one end of the pipeline 132; the pipeline 132 is fixed inside the side wall of the cylinder 110, and the other end of the pipeline 132 is located outside the cylinder 110 so that the water pump 131 can completely empty the water in the cylinder 110.

[0035] In actual application, considering that it is impossible for the cylinder 110 to be completely free of seawater leakage, in order to ensure the safety and quality of maintenance work, the height of the water suction port of the water pump 131 should be set below the bottom plate of the lower anchor 200 of the dock door, so that the lower anchor 200 of the dock door is in a waterless environment. At the same time, the displacement of the water pump 131 needs to be determined according to the actual amount of seawater infiltration, and in principle must be more than twice the seawater leakage rate, so as to ensure that the seawater in the cylinder 110 can be effectively drained.

[0036] Preferably, in this embodiment, in order to ensure the effectiveness of the water pump 131, the water pump assembly 130 may also include a liquid level sensor, which is communicatively connected to the water pump 131; the liquid level sensor is configured as follows: when the liquid level sensor detects that the accumulated water in the cylinder 110 reaches a preset water level, the water pump 131 is started to pump water, thereby ensuring that the height of the infiltrated seawater does not exceed the warning height, thereby ensuring the safety and effectiveness of the maintenance operation.

[0037] Furthermore, in this embodiment, if Figure 4 As shown, the dock door lower capstan watertight barrel tooling also includes a lift 150; the lift 150 is arranged inside the side wall of the barrel 110. In this way, maintenance personnel can enter the barrel 110 from the outside through the lift 150 to perform maintenance work.

[0038] Preferably, considering that the maintenance process may take a long time, the personnel need to take a proper rest during the maintenance process. The personnel climbing the ladder back and forth to the outside of the cylinder 110 to take a rest will consume the personnel's physical strength and working time. However, if the personnel stay at the bottom of the cylinder 110, there may be a threat to the personnel's safety due to lack of oxygen and seawater leakage. Therefore, in this embodiment, if Figure 4 As shown, a resting platform 160 is provided at a preset height of the inner wall of the cylinder 110, and the elevator 150 is partially provided at the resting platform 160. In this way, when a person needs to rest, he can climb a section of the elevator 150 to reach the resting platform 160 for rest, which not only ensures the safety of the person, but also saves the person's physical strength.

[0039] Preferably, a plurality of resting platforms 160 may be provided at different heights to facilitate personnel to take a rest while climbing the ladder, thereby avoiding accidental falls caused by energy consumption while climbing the ladder, and improving the safety of personnel operations.

[0040] In an operative solution, in order to facilitate the processing of the cylinder 110, the cylinder 110 is composed of a plurality of sub-cylinders stacked along the axial direction of the cylinder, and each of the sub-cylinders has openings at the top and the bottom.

[0041] Specifically, the top opening of the sub-cylinder is consistent in size with the bottom opening of the sub-cylinder located above and adjacent to it. For example, the sub-cylinder located in the middle part only has side cylinder walls, but does not have a cylinder top and a cylinder bottom, and then the side cylinder walls of multiple sub-cylinders are sealed and connected by welding or riveting. In this way, it is convenient to quickly build a cylinder 110 of a required length to adapt to the maintenance work of the lower winch seat of the dock door of different depths, thereby improving the construction speed and efficiency.

[0042] When the dock door lower capstan watertightening cylinder tooling provided in this embodiment is used to perform maintenance work on the dock door lower capstan, the process is roughly as follows:

[0043] First, after the dock gate floats away, with the assistance of a crane, the prefabricated cylinder 110 (containing a water pump assembly, a lift, a rest platform, etc.) is placed directly above the dock gate's lower capstan 200. This process requires divers to observe and direct underwater to ensure that the cylinder 110 falls vertically and that the sealing ring 140 at the lower end of the cylinder 110 fits evenly and tightly with the base surface of the dock gate's lower capstan 200.

[0044] Then, the cylinder 110 is fixed to the dock surface by using the fastening device 120 , which can be fixed by bolts or welding to ensure that the cylinder 110 does not shake.

[0045] Afterwards, the water pump 131 is started to pump water, so that all the water in the cylinder 110 is pumped out and drained. In the subsequent operation process, when the accumulated water reaches a certain amount, the water pump 131 is turned on to pump water to ensure that the maintenance area in the cylinder 110 is in a water-free state.

[0046] Next, when the environment inside the cylinder 110 meets the conditions for maintenance work, the personnel reach the lower winch seat 200 of the dock door via the elevator 150 to carry out maintenance work.

[0047] Finally, when the maintenance work is completed, the personnel return via the elevator 150, remove the fastening device 120, retract the cylinder 110 and disassemble it.

[0048] In this way, the enclosure of the winch seat under the dock door can be achieved in a shorter construction period, and the safety of the maintenance personnel and the quality of the maintenance can be guaranteed.

[0049] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other. In addition, the different parts between the various embodiments can also be used in combination with each other, and the present utility model is not limited to this.

[0050] The dock gate lower capstan watertight cylinder tooling provided in this embodiment includes: a cylinder body, the top and bottom of the cylinder body have openings, and the opening at the bottom is used to accommodate the dock gate lower capstan; a fastening device, arranged on the outside of the side wall of the cylinder body, used to connect and fix the cylinder body to the dock gate side wall; a water pump assembly, including a water pump and a pipeline, the water pump assembly is configured as follows: the water pump pumps out the water in the cylinder body and discharges it to the outside of the cylinder through the pipeline. The cylinder body can separate the dock gate lower capstan from the seawater when the construction enclosure range is minimized, and the water in the cylinder body can be pumped out by the water pump assembly, ensuring that the dock gate lower capstan is always in a waterless environment during maintenance. Due to the small size of the cylinder body, the construction cost is low and the cycle is short. In this way, not only the maintenance cost is reduced, but also the maintenance effect can be guaranteed, solving the problem of high maintenance cost and low efficiency of the existing dock gate lower capstan.
