Description

Technical Field

[0001] This utility model relates to the field of gas filtration technology, and in particular to an air inlet filter cotton fixing frame and a motor cooling system. Background Technology

[0002] Because the working environment of quay cranes is characterized by high dust, high humidity, and high salt spray, the air inlet of the motor cooling system of the quay crane (quayside container crane) drive mechanism is filtered with filter cotton to protect the motor from the harsh environment.

[0003] The filter cotton at the air inlet of the existing motor cooling system is fixed in position using a fixed mesh frame. The fixed mesh frame includes a fixed frame and a wire mesh. The fixed frame is a quadrilateral frame structure, and the wire mesh is installed on the front and rear sides of the fixed frame. The filter cotton is detachably installed inside the fixed frame. The fixed frame is a detachable structure, and adjacent profiles are fixedly connected by bolts.

[0004] The existing filter cotton fixing frame structure, because the filter cotton is installed inside the fixing frame, means that when only the top profile of the fixing frame is removed, the entire filter cotton is still inside the fixing frame, and the top of the filter cotton does not protrude from the fixing frame, making it difficult to pull out the filter cotton. Therefore, it is usually necessary to remove all the bolts at the four corners to disassemble the fixing frame and then remove the filter cotton. The whole disassembly process is cumbersome and time-consuming. Moreover, because the wire mesh is irregular, it is very easy to cut hands during the disassembly process, resulting in poor safety. Utility Model Content

[0005] To address the problems of existing filter cotton fixing mesh structures in the background art, such as cumbersome and time-consuming disassembly processes, and the risk of hand injuries due to irregular wire mesh, resulting in poor safety, this utility model provides an air inlet filter cotton fixing mesh structure.

[0006] The technical solution of this utility model is as follows: This utility model provides an air inlet filter cotton fixing frame, including two frames hinged together. The two frames can be unfolded into a horizontally coplanar state. A mounting hole is provided in the middle of each frame, and a wire mesh is fixedly installed at the mounting hole. Filter cotton is placed between the two wire meshes after the two frames are folded. Ear plates are also fixed on the frames, with the ear plates facing each other and fixed together by bolts. By hinged together, the two frames can be rotated and unfolded around the hinge by simply removing the bolts at the ear plates, without disassembling the entire frame, allowing easy removal of the filter cotton. This greatly simplifies the filter cotton replacement process, saving time and labor costs. It also avoids excessive contact with irregular wire mesh during frame disassembly, reducing the risk of hand injuries and improving safety during use.

[0007] Preferably, the two frames are hinged together. Using a hinge to connect the two frames ensures a stable connection and flexible rotation, which can ensure that the frames are stable and reliable during opening and closing, guaranteeing the stability and service life of the structure, and further improving the convenience of operation.

[0008] Preferably, the ear plates and hinges are distributed on opposite sides of the frame, so that the two frames are more evenly stressed and more firmly connected when closed and fixed, which prevents the frames from loosening during use. It also makes the disassembly and installation of bolts easier, improving the stability and ease of operation of the overall structure.

[0009] Preferably, the frame is a rectangular frame structure. The rectangular frame structure is more compatible with the shape of the air inlet of the motor cooling system, and can be installed more stably at the air inlet. It is also easier to match the shape of the filter cotton, ensuring the stability of the filter cotton after installation and improving the practicality of the overall structure.

[0010] Preferably, the installation holes are rectangular holes, which are compatible with the rectangular frame and filter cotton. This maximizes the use of the frame space, ensures the effective coverage area of ​​the wire mesh, and thus ensures the filtration effect of the filter cotton. It also facilitates the processing and installation of the wire mesh.

[0011] Preferably, the wire mesh is located close to the outer side of the frame, and the thickness of the wire mesh is less than the depth of the installation hole. This prevents the wire mesh from protruding from the frame surface, reduces direct friction between the hand and the wire mesh during operation, lowers the risk of scratches, improves safety, and also provides space for the installation of the filter cotton, facilitating the installation and positioning of the filter cotton.

[0012] Preferably, the wire mesh is welded together from several steel wires arranged in a cross pattern in the horizontal and vertical directions. The cross-section of the steel wires is circular, which can reduce sharp edges and lower the possibility of hand injuries.

[0013] Preferably, a handle is fixed on the frame to facilitate the operator to open and close the frame, making the operation of replacing the filter cotton more labor-saving and convenient, while avoiding contact between the hands and the wire mesh, reducing the risk of scratches.

[0014] Preferably, the handle and the ear plate are on the same side, allowing the operator to easily rotate the frame through the handle on the same side, making the frame unfold more smoothly, optimizing the operation process and improving the replacement efficiency.

[0015] This utility model provides a motor cooling system, including the aforementioned air inlet filter cotton fixing frame. During the maintenance of the motor cooling system, replacing the filter cotton is more convenient and efficient, reducing downtime due to maintenance, while improving the operational safety of maintenance personnel and ensuring the stable operation of the motor cooling system.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are: 1. By hinged together, the two frames can be rotated and unfolded around the hinge by simply removing the bolts at the ear plate. The filter cotton can be easily removed without disassembling the entire frame, which greatly simplifies the filter cotton replacement process and saves time and labor costs. At the same time, it avoids excessive contact with irregular wire mesh due to disassembling the fixed frame, reduces the risk of hand cuts, and improves the safety of use.

[0017] 2. The wire mesh is installed inside the installation hole and close to the outside of the frame. The thickness of the wire mesh is less than the depth of the installation hole, which can prevent the wire mesh from protruding from the surface of the frame, reduce direct friction between the hand and the wire mesh during operation, reduce the risk of scratches, improve safety, and also leave space for the installation of filter cotton, making it easier to limit the installation of filter cotton.

[0018] 3. A handle is fixed on the frame, which makes it easy for operators to open and close the frame, making it easier and more convenient to replace the filter cotton. At the same time, it avoids contact between the hands and the wire mesh, reducing the risk of scratches. Attached Figure Description

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] Example 1 In a typical embodiment of this utility model, such as Figures 1-5 As shown, an air inlet filter cotton fixing frame is proposed, including: a frame 1, a wire mesh 2, an ear plate 4, and a hinge 5. There are two frames 1, which are hinged together by the hinge 5. The two frames 1 can be unfolded into a horizontal coplanar state. The middle part of the frame 1 is empty, and the wire mesh 2 is fixedly installed in the middle of the empty part of the frame 1 to cover the middle part. The filter cotton is placed between the two frames 1. The wire mesh 2 is used to block and limit the two sides of the filter cotton, while allowing the gas to pass through, so as to achieve filtration. The ear plate 4 is fixedly installed on the side of the frame 1 opposite to the hinge 5 for bolt installation, thereby fixing the two frames 1 together.

[0023] Specifically, the frame 1 is a rectangular frame structure, and the middle area of ​​the frame 1 has a mounting hole 6. The mounting hole 6 is a rectangular hole that penetrates the frame 1. The wire mesh 2 is fixedly installed in the mounting hole 6 to cover the mounting hole 6.

[0024] The wire mesh 2 is located close to the outer side of the frame 1, and the thickness of the wire mesh 2 is less than the depth of the installation hole 6. On the one hand, this prevents the wire mesh 2 from being exposed, reducing the risk of scratches. On the other hand, it also provides installation space for the installation limit of the filter cotton. It can be understood that the distance between the two wire meshes 2 on the two frames 1 is not less than the thickness of the filter cotton.

[0025] In this embodiment, the wire mesh 2 is welded together from several horizontally and vertically interlaced wires. The cross-section of the wires is circular, which avoids scratching the hands. The periphery of the wire mesh 2 is fixedly connected to the side wall of the mounting hole 6. During the replacement of the filter cotton, there is no need to remove the wire mesh 2, which facilitates the operation and avoids the risk of hand injury.

[0026] like Figure 2As shown, two ear plates 4 are welded and fixed on each frame 1. The two ear plates 4 are located on the same side and are arranged opposite each other. The ear plates 4 are provided with through holes 7 for bolt installation. The ear plates 4 on the two frames 1 correspond one to one, so as to realize the fixed connection between the ear plates 4 by bolts, thereby locking and fixing the relative position between the two frames 1.

[0027] To further improve operational safety, a handle 3 is welded and fixed to the frame 1. The handle 3 is on the same side as the ear plate 4, and the handle 3 is located between the two ear plates 4. That is, the two ear plates 4 are fixedly set on both sides of the handle 3. The handle 3 facilitates the opening and closing of the frame 1, and the operator's hands do not need to touch the wire mesh 2 and other structures, making it safer to use. In this embodiment, the handle 3 is an inverted U-shape and is made of metal for easy hand use.

[0028] like Figure 4 and Figure 5 As shown, the frames 1 are hinged together by hinges 5. The hinges 5 are hinge structures and include hinge bushings and pivots. The hinge bushings are welded and fixed to the frames 1. The hinge bushings on the two frames 1 are alternately arranged in sequence, and all the hinge bushings are connected by pivots, thereby realizing the rotational connection between the two frames 1.

[0029] The specific working principle is as follows: Remove the fixed mesh frame from the air inlet, then remove the bolts at the ear plate 4. Hold the handle 3 and separate the two frames 1 so that the two frames 1 are unfolded and horizontally 180°. Take out the old filter cotton and install the new filter cotton into the installation hole 6. After the filter cotton is installed, hold the handle 3 and fasten the two frames 1 together. Use bolts to fix the ear plates 4 on the two frames 1 to lock the relative positions of the two frames 1. Reinstall the fixed mesh frame at the air inlet.

[0030] Example 2 In another typical embodiment of this utility model, a motor cooling system is proposed for air cooling of the motor of the quay crane drive mechanism. The motor cooling system includes an air inlet filter cotton fixing mesh frame, which is detachably installed at the air inlet of the motor cooling system.

[0031] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
