Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding mechanical processing, in particular to a jacking device for a guide plate in a ship gas release unit. Background Art

[0002] As the International Maritime Organization (IMO) continues to increase its requirements for energy conservation and emission reduction, reducing ship energy consumption has become a development trend in the shipping industry. As a cutting-edge technology with significant energy-saving effects, air lubrication and drag reduction technology has attracted much attention from shipowners, shipyards and design units for its wide adaptability and significant energy-saving effects. Its working principle is a method of using air bubbles to reduce the resistance between the hull and the seawater. Specifically, the gas is quickly pumped out through the gas release unit located at the bottom of the ship's outer plate. At this time, the honeycomb-shaped bubbles will quickly unite and form a 1 cm to 2 cm air layer on the outer plate of the hull. Since the resistance of air is much smaller than that of water, it can reduce the resistance of the ship during navigation to achieve the effect of saving energy. This type of method can reduce carbon dioxide emissions by about 10% to 15%. The air lubrication drag reduction system consists of an air compressor, a gas release unit and a series of pipelines and accessories. The core device is the gas release unit, which consists of a main structure, pipelines and guide plates. Due to the special location, the guide plates cannot be transported and installed using tools such as forklifts and cranes. Therefore, the installation and transportation of the guide plates during construction need to be solved to meet the installation requirements of the product. Summary of the invention

[0025] Example 1

[0026] As shown in the figure, the lifting device for the guide plate in the ship gas release unit provided in this embodiment includes a main frame 1 and a transmission rod 4;

[0027] A hydraulic jack 10 is installed at the bottom of the main frame 1, and a working panel 2 is fixedly installed at the top of the transmission rod 4. The other end of the transmission rod 4 passes through the top of the main frame and is located above the hydraulic jack 10.

[0028] The transmission rod 4 is also fixedly mounted with a vertical limiting structure 5, and the vertical limiting structure 5 limits the descending height of the transmission rod 4 when the transmission rod 4 descends;

[0029] It also includes a guide and limit structure 6, which is installed on the main frame 1. The transmission rod 4 passes through the guide and limit structure, and the guide and limit structure guides the transmission rod 4 to rise and fall.

[0030] It also includes an auxiliary reinforcement plate 3, which is installed at the angle between the working panel 2 and the transmission rod 4. The auxiliary reinforcement plate 3 can assist the working panel 2 to enhance the supporting load capacity;

[0031] It also includes a support plate 7, which can be made of a steel plate. The support plate 7 is fixedly mounted at the end of the transmission rod 4 and can better withstand the lifting force given to the support plate by the hydraulic jack 10;

[0032] It also includes a base 8, which is installed at the bottom of the main frame 1 and keeps the center alignment with the transmission rod 4, and the hydraulic jack 10 is fixedly installed on the base 8. Similarly, the hydraulic jack 10 and the transmission rod 4 also keep the center alignment, and the base plays a supporting role in the force generated by the hydraulic jack lifting;

[0033] It also includes a plurality of sliding wheels 9, which are installed at the bottom of the main frame 1. The sliding wheels facilitate the movement of the jacking device, which not only facilitates the transportation of the guide plate, but also provides better and more accurate positioning for the installation of the guide plate;

[0034] In this embodiment, there are at least two groups of guide and limit structures 6. More specifically, the guide and limit structures can be support frames or support rods, which are fixedly mounted on the main frame 1. The transmission rod 4 can pass through the support frames or support rods, and the transmission rod 4 can be guided by the support frames or support rods when moving up and down. In addition, the vertical limit structure 5 in this embodiment is a limit block fixedly mounted on the transmission rod 4, and the limit block cannot pass through the top of the main frame 1, so that the descending height of the transmission rod 4 is limited when it descends.

[0035] It can be considered that the main frame 1 can be composed of angle steel and connected by welding. Its bearing strength meets the weight and lifting requirements of the guide plate, and it has reliable performance and simple production. The working panel 2 is made of steel plate, which is in contact with the guide plate plane and plays a role in supporting the guide plate. The transmission rod 4 adopts high-strength steel pipe and is the connecting and supporting component of the jacking device. The hydraulic jack 10 obtains the transmission force through the jack lifting principle to complete the lifting and lowering of the guide plate.

[0036] As an example, in actual use, the guide plate is placed on the working panel, moved to the bottom of the gas release unit on the outer plate side of the ship through the sliding wheel, and the lifting height of the hydraulic jack is adjusted to complete the positioning of the guide plate, and then moved to the precise position through the sliding wheel 9, and the hydraulic jack 10 is adjusted again to lift the guide plate into the gas release unit groove and install it tightly.

[0037] like Figure 3 The specific installation steps are as follows:

[0038] Step 1: Move the lifting device to an open position on the bottom side of the ship (without any obstacles above), and use a forklift to place the guide plate on the working panel;

[0039] Step 2: Push the lifting device to move the guide plate to the bottom of the gas release unit via the sliding wheel;

[0040] Step 3: Adjust the hydraulic jack to raise, and raise the guide plate to the groove position below the gas release unit through the transmission rod. During the rising process, the transmission rod moves along the guide limit structure to control the vertical output of the transmission force;

[0041] Step 4: Adjust the position of the guide plate again by lifting with sliding wheels and hydraulic jacks to achieve precise alignment;

[0042] Step 5: After alignment, adjust the jack to lift the guide plate into the groove of the gas release unit, and complete the bolt installation and torque tightening;

[0043] Step 6: Measure the relevant gaps to check the assembly accuracy. If the measured data meets the specified value requirements, the guide plate installation is now complete.

[0044] Step seven, lower the hydraulic jack to zero position, move it to the initial position, and install the next guide plate.

[0045] The above-mentioned ship gas release unit guide plate jacking device can move the guide plate to a position that cannot be transported by engineering vehicles and manpower through a sliding wheel device, and does not require human support when positioning and installing in the air. It has strong stability, reliable safety performance, convenient movement and high positioning accuracy. The overall structure of the jacking device of the present invention is completed by assembling and welding angle steel, high-strength steel pipe, channel steel and steel plate. It has low material cost, simple overall structure, high bearing strength and convenient movement. It can be used in small spaces, and the components are mechanically matched with each other, have high reliability, are easy to operate and can be reused.

[0046] The above embodiments describe the present invention in detail, but the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of application of the present invention shall still fall within the scope of the patent coverage of the present invention.
