Description

Technical Field

[0001] This application relates to the field of air cooler installation technology, and in particular to a hoisting marine air cooler and its vibration damping structure. Background Technology

[0002] Marine air coolers are mainly used for refrigeration in ships. For products that need to be kept fresh or frozen during transportation, marine air coolers can effectively solve the problems of product preservation and freezing.

[0003] Currently, shipboard air coolers are fixed to the casing directly with bolts. However, the usage scenarios for shipboard air coolers differ from those for industrial air coolers. In industrial environments, they are generally fixed to walls, so there is no issue with turbulence. However, ships experience some turbulence, causing the air cooler casing to be subjected to vibrations. Over time, the nuts securing the casing may loosen, leading to impacts between the casing's mounting point and the ship's installation location, thus affecting the lifespan of the air cooler.

[0004] Regarding the aforementioned technologies, the inventors believe it is necessary to reduce the vibration of the air cooler casing. Utility Model Content

[0005] The purpose of this application is to provide a vibration damping structure for a hoisted marine air cooler to improve the problem of chassis vibration.

[0006] This application provides a vibration damping structure for a hoisting marine air cooler, which adopts the following technical solution:

[0007] A vibration damping structure for a hoisting marine air cooler includes a hull mounting plate, a fixing screw fixed to the hull mounting plate, and a fixing nut threadedly connected to the fixing screw. The air cooler mounting plate is located between the hull mounting plate and the fixing nut. The air cooler mounting plate has a through-hole for the fixing screw to be inserted. An elastic block is provided between the air cooler mounting plate and the fixing nut. The elastic block has a through-hole for the fixing screw to be inserted.

[0008] By adopting the above technical solution, when the fixing nut squeezes the elastic block, the elastic block has a reaction force along its axis on both the air cooler mounting plate and the fixing nut; this causes the threads between the fixing nut and the fixing screw to engage, keeping the fixing nut locked for a long time, thereby reducing the loosening of the fixing nut; it also prevents gaps from forming on the air cooler mounting plate, which could cause impacts between the air cooler mounting plate and the ship's installation location, thus improving the problem of chassis vibration.

[0009] Optionally, a compression spring is embedded inside the elastic block.

[0010] By adopting the above technical solution, the compression spring can maintain the elasticity of the elastic block for a longer period of time, thus extending the service life of the elastic block; the compression spring is located inside the elastic block, which also serves to prevent rust on the compression spring.

[0011] Optionally, the compression spring is provided with abutment pieces at both ends.

[0012] By adopting the above technical solution, the compression spring abuts against the inside of the rubber block through the abutment piece, thereby increasing the contact area between the compression spring and the elastic block, so that the compression spring pressure is evenly received, thus protecting the elastic block.

[0013] Optionally, the abutment piece is provided with a plurality of through holes for securing.

[0014] By adopting the above technical solution, the setting of the embedded through hole can better embed the abutment piece and the elastic block together, and also save materials.

[0015] Optionally, the outer wall of the abutment piece is provided with reinforcing ribs.

[0016] By adopting the above technical solution, the reinforcing ribs can improve the strength and hardness of the abutment piece, and at the same time, increase the contact area between the abutment piece and the elastic block, so that the compression spring and the elastic block have a better fixing effect.

[0017] Optionally, a magnetic element is embedded inside the elastic block and on the side near the air cooler mounting plate, and the magnetic element is magnetically attracted to the air cooler mounting plate.

[0018] By adopting the above technical solution, when the elastic block is fitted onto the fixing nut, the operator does not need to hold it. The magnetic components and the air cooler mounting plate are attracted by magnetism, which prevents the elastic block from falling off. The operator can free up their hands to tighten the fixing nut, which is convenient for construction.

[0019] Optionally, the outer wall of the elastic block and near the magnetic element is provided with a protrusion.

[0020] By adopting the above technical solution, construction personnel can effectively identify which end of the elastic block the magnetic component is located, making it easier for them to install it correctly and avoiding reverse installation.

[0021] Another objective of this application is to provide a hoisting marine air cooler to improve the problem of chassis vibration.

[0022] A hoisting marine air cooler includes the aforementioned shock-absorbing structure for hoisting marine air coolers.

[0023] By adopting the above technical solution, when the fixing nut squeezes the elastic block, the elastic block has a reaction force along its axis on both the air cooler mounting plate and the fixing nut; this causes the threads between the fixing nut and the fixing screw to engage, keeping the fixing nut locked for a long time, thereby reducing the loosening of the fixing nut; it also prevents gaps from forming on the air cooler mounting plate, which could cause impacts between the air cooler mounting plate and the ship's installation location, thus improving the problem of chassis vibration.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When the elastic block is compressed, it exerts an axial force on the fixing nut, causing the threads between the fixing nut and the fixing screw to engage, thus locking the fixing nut and reducing loosening; preventing gaps from forming on the air cooler mounting plate, which could cause impact between the air cooler mounting plate and the ship's installation location, and improving the problem of chassis vibration;

[0026] 2. The combination of the elastic block and the compression spring can effectively prolong the effect of the elastic force;

[0027] 3. By incorporating magnetic components and protrusions within the elastic element, the operator's work efficiency is improved, enabling rapid installation. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below. Example 1

[0033] A vibration damping structure for a hoisted marine air cooler, referring to Figure 1 and Figure 2It includes a hull mounting plate 1, a fixing screw 2, and a fixing nut 21; the fixing screw 2 is threadedly fixed to the hull mounting plate 1, and the upper end of the fixing screw 2 is threadedly fixed by a wooden block (not shown in the figure), the wooden block is located on the upper surface of the hull mounting plate 1, and is fixed by hemispherical concrete pouring; the fixing nut 21 is threadedly connected to the fixing screw 2.

[0034] Reference Figure 2 Between the hull mounting plate 1 and the fixing nut 21 is the air cooler mounting plate 3. The air cooler mounting plate 3 has a through mounting hole 31 for the fixing screw 2 to be inserted to install the casing.

[0035] Reference Figure 2 and Figure 3 An elastic block 4 is provided between the air cooler mounting plate 3 and the fixing nut 21. The elastic block 4 can be made of rubber or elastic resin. The elastic block 4 has a through hole 41 for the fixing bolt to be inserted.

[0036] Reference Figure 2 and Figure 3 A compression spring 42 is embedded inside the elastic block 4 to enhance its elasticity over a long period. Abutment pieces 5 are provided at both ends of the compression spring 42. When the elastic block 4 is subjected to force, the compression spring 42 abuts against the elastic block 4 through the abutment pieces 5, preventing damage to the elastic block 4. The abutment pieces 5 and the compression spring 42 are fixed together by welding. During the melt injection molding of the elastic block 4, the abutment pieces 5 and the compression spring 42 serve as inserts. After the elastic block 4 is formed, the abutment pieces 5 and the compression spring 42 are embedded inside the elastic block 4. The abutment piece 5 has a through hole for the fixing screw 2 to pass through. The abutment piece 5 and the compression spring 42 can be connected by welding, or they can be left unconnected.

[0037] Reference Figure 2 and Figure 3 The abutment piece 5 is provided with several through holes 51 to better fix the abutment piece 5 and the elastic block 4 relative to each other; the outer wall of the abutment piece 5 is provided with reinforcing ribs 52, which are formed by stretching the abutment piece 5 to improve the hardness of the abutment piece 5.

[0038] Reference Figure 2 and Figure 3 The elastic block 4 has a magnetic component 43 inside, which is a magnet; the elastic block 4 is located on the side close to the air cooler mounting plate 3 and is fixed in place; the magnetic component 43 is magnetically attracted to the air cooler mounting plate 3 so that the elastic block 4 can be attracted to the air cooler mounting plate 3.

[0039] Reference Figure 2 and Figure 3The outer wall of the elastic block 4 is provided with a protrusion 44, which is located near the magnetic component 43, so as to identify the direction of the elastic block 4 and improve construction efficiency.

[0040] The implementation principle of this application embodiment is as follows:

[0041] During installation, the mounting holes 31 on the air cooler mounting plate 3 correspond to the fixing screw 2 for easy insertion; the elastic block 4 is fitted onto the fixing screw 2, with the protrusion 44 facing the side of the air cooler mounting plate 3; when the elastic block 4 is close to the air cooler mounting plate 3, the elastic block 4 adheres to the air cooler mounting plate 3, eliminating the need for the operator to hold it continuously.

[0042] Then, thread the fixing nut 21 to the fixing screw 2 until the fixing nut 21 and the air cooler mounting plate 3 tighten the elastic block 4; the installation process is complete.

[0043] During use, when there is a bump, the elastic block 4 and the compression spring 42 keep the fixing nut 21 and the air cooler mounting plate 3 in contact and are subjected to its axial force, so that their threads are engaged, reducing the loosening of the fixing nut 21, thereby improving the problem of chassis vibration.
