Description

Technical Field

[0001] The utility model relates to the technical field of marine low-speed diesel engines, in particular to a peripheral fixing device for a grille bracket platform of a marine low-speed diesel engine. Background Art

[0002] Marine low-speed diesel engines are a crucial component of ship propulsion systems, offering high power, long service life, and easy operation and maintenance. They are primarily used for propulsion in ocean-going vessels and are widely used in ocean-going cargo ships, oil tankers, and ultra-large cargo vessels ranging from 2,000 to 500,000 tons. These engines typically utilize a grid support platform, which provides stable support and anchoring, ensuring stability and safety during ship operation. Ensuring the stability and safety of the grid support platform is crucial, requiring the use of a side fixture.

[0003] The common edge fixtures for marine low-speed diesel engine grille bracket platforms typically consist of a fixing frame, connectors, fastening devices, auxiliary structures, and protective devices. The fixing frame supports and secures the entire edge fixture, with connectors tightly connecting the fixing frame to the grille bracket platform. The fastening devices secure the connectors to ensure the stability of the edge fixture. The auxiliary structures enhance the rigidity and stability of the fixing frame, preventing deformation or damage from vibration or impact. The protective devices protect the fixture from environmental corrosion.

[0004] Traditionally, the grille bracket platform for marine low-speed diesel engines features a fold-up edge as a common safety feature, effectively reducing the risk of items falling from the platform's accessways. However, this approach, in line with the engine's outline drawing approval agreement, has led some shipyards to implement refined approval requirements, requiring docking platform shipyards to eliminate guardrails and fold-up edges. Consequently, while meeting customer requirements, this approach still presents the challenge of failing to effectively protect the engine during production. Therefore, a fold-up edge fixing device for the grille bracket platform for marine low-speed diesel engines is proposed. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the utility model provides a surround fixing device for a marine low-speed diesel engine grille bracket platform to solve the technical problem of effectively protecting the main engine during the production process of the above-mentioned high-power low-speed diesel engine without the upward-flip surround.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a device for fixing the edge of a grille bracket platform for a marine low-speed diesel engine, comprising:

[0009] A platform passageway and a flat steel edge provided on the front of the platform passageway, with a fixing device installed on the top of the flat steel edge;

[0010] The fixing device is composed of clips, nuts and bolts, and the bolts are added on both sides of the front center of the clips, and the nuts are threadedly connected to the outer surface of the bolts. By installing flat steel edges on the platform channel, the edge of the platform channel is surrounded to prevent objects from slipping from the platform channel. The clips, nuts and bolts form a fixing device, and the flat steel edges are fixed to both sides of the platform channel through the fixing device to prevent objects from falling from the edge of the platform channel. When the diesel engine is shipped to the shipyard and installed in the engine room, the clips and flat steel edges on both sides of the platform channel are removed, and the engine room platform and the shipyard platform channel are effectively combined together. In this way, detachable grille edge protection is achieved, which solves the problem of effective safety protection of the main engine during the production process of high-power low-speed diesel engines by eliminating the upward-turning edges.

[0011] Preferably, the buckle is composed of a semicircular plate and a side connecting plate, and the side connecting plate is located at the front and rear ends of the bottom of the semicircular plate. The top two sides of the side connecting plate are provided with fixing grooves, and fixing rods are inserted into the inner cavity of the fixing grooves. The side connecting plate is connected to the corresponding structure through the fixing grooves and the fixing rods.

[0012] Preferably, connecting plates are provided on both sides of the lower part of the front and back sides of the semicircular plate, and a bidirectional screw is connected to the inner cavity of the connecting plate. Sliders are provided on the front and rear sleeves of the bidirectional screw, and the size and shape of the sliders correspond to those of the fixed slots, and fixed sockets are provided on both sides of the slider, and the size and shape of the fixed plug rods correspond to those of the fixed plug rods. When the slider is inserted into the fixed slot and the fixed plug rod is inserted into the fixed socket, the slider is connected to the side connecting plate. The bidirectional screw is rotated on the connecting plate, so that the slider drives the side connecting plates to move toward each other according to the direction of the bidirectional screw, thereby adjusting the distance between the side connecting plates. This allows the structure to be adjusted and used according to different situations within a certain range, and the side connecting plates can be replaced, thereby improving the practicality and applicability of the device.

[0013] Preferably, a rotating handle is provided on the front surface of the connecting plate and is coaxially connected to the bidirectional lead screw. Positioning slots are evenly formed on the outer side of the front surface of the rotating handle, and positioning rods are provided within the inner cavity of the positioning slots. The positioning rods are inserted and connected to the connecting plate. The rotating handle drives the bidirectional lead screw to rotate on the connecting plate and adjusts the direction of the bidirectional lead screw. When the rotating handle is rotated, the positioning rod is inserted into the connecting plate through the positioning slot, connecting the connecting plate and the rotating handle, thereby ensuring the stability of the rotating handle and the bidirectional lead screw.

[0014] Preferably, a connecting frame is provided at the center of both sides of the top of the semicircular plate and is connected to the connecting plate, a guide rod is inserted into the center of the top of the connecting frame, and first limiting grooves are provided on both sides of the center of the top of the connecting frame. The connecting frame is connected to the connecting plate, and the guide rod is connected to the corresponding structure through the connecting frame.

[0015] Preferably, limit blocks are installed on the upper and lower surfaces of the guide rod, and the two sets of limit blocks are positioned opposite each other. The lower portion of the guide rod is inserted into the centers of both sides of the top of the semicircular plate, and second limit slots are formed at the front and rear ends of the centers of both sides of the top of the semicircular plate. The guide rod drives the limit blocks to be inserted into the interior of the semicircular plate through the connecting frame and then rotated, so that the limit blocks on the upper and lower portions of the guide rod are misaligned with the first limit slot and the second limit slot, thereby ensuring the stability of the connection between the guide rod, the connecting frame and the semicircular plate, and facilitating assembly and disassembly operations.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a device for fixing the edge of a grille bracket platform for a marine low-speed diesel engine, which has the following beneficial effects:

[0018] The edge fixing device of the grille bracket platform for a low-speed marine diesel engine is designed to secure the platform channel by installing a flat steel edge around the channel. Clips, nuts, and bolts form a fixing device that secures the flat steel edge to both sides of the channel. When the diesel engine is shipped to the shipyard and installed in the engine room, the clips and flat steel edge on both sides of the channel are removed, effectively integrating the engine room platform with the shipyard platform channel. This provides detachable grille edge protection, effectively protecting the main engine during production without the flip-up edge, and preventing objects from falling from the edge of the channel.
