Description

Technical Field

[0001] This utility model relates to the field of mounting base technology, specifically an adjustable diesel engine mounting base. Background Technology

[0002] Marine diesel engines, as the "heart" of a ship, are core equipment providing propulsion power and auxiliary electricity. The stability and precision of their installation directly affect the ship's operational safety, vibration and noise levels, and transmission efficiency. Because ships sail in complex marine environments for extended periods, enduring swaying, impacts, and continuous vibrations caused by wind and waves, the rigidity, impact resistance, and reliability of diesel engine mounting bases are required to be far greater than those for land-based equipment.

[0003] Currently, in the field of shipbuilding and repair, traditional diesel engine mounting bases mostly adopt fixed welded structures or rigid bases with limited height adjustment range. Although these traditional bases are simple in structure, they lack sufficient flexibility and can only be installed once for a specific model of diesel engine. When it is necessary to replace diesel engines of different models or sizes, or when precise height alignment is required during maintenance, the existing bases are often difficult to adjust, and may even require destructive modifications such as on-site cutting and welding. This is not only time-consuming and labor-intensive, increasing costs, but may also introduce new structural strength risks due to improper modifications. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an adjustable diesel engine mounting base.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An adjustable diesel engine mounting base, comprising:

[0007] The U-shaped base can be detachably fixed to the installation position;

[0008] The U-shaped mounting bracket is vertically and adjustablely installed inside the U-shaped base;

[0009] Multiple mounting holes are formed along the width direction on both sides of the U-shaped mounting bracket and arrayed along the height direction on both sides of the U-shaped base;

[0010] Multiple auxiliary plates are rotatably installed inside the two side walls of the U-shaped base, and the auxiliary plates can be rotated to a horizontal position to extend into the interior of the U-shaped base;

[0011] The lower and upper rotating slots are formed in the side walls of the U-shaped base, located below and above the auxiliary plate, respectively. The lower and upper rotating slots are configured to allow the auxiliary plate to rotate from the horizontal direction to the vertical direction.

[0012] The rotation point of the auxiliary plate is projected vertically into the upper rotating groove; by switching between the vertical and horizontal states of the auxiliary plate, the U-shaped mounting bracket can avoid obstacles when adjusting its height and provide support during installation.

[0013] Preferably, when the U-shaped mounting bracket abuts against the upper surface of the horizontal auxiliary plate, the mounting holes on the U-shaped mounting bracket correspond one-to-one with the mounting holes on the side wall of the U-shaped base.

[0014] Preferably, when the auxiliary plate is rotated to a horizontal position, the auxiliary plate is located inside the side wall of the U-shaped base and abuts against the inner top wall of the U-shaped base.

[0015] Preferably, the depth and width of the lower and upper rotating slots are configured to provide clearance when the auxiliary plate rotates, thereby avoiding interference with the sidewalls of the U-shaped base.

[0016] Preferably, the auxiliary plate is rotatably mounted on both sides of the U-shaped base via a rotating shaft, and the vertical projection of the rotating shaft is located within the upper rotating groove.

[0017] Preferably, the mounting hole is a threaded hole or a through hole, and the U-shaped base and the U-shaped mounting bracket are made of metal.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The emergency support surface formed by the horizontal auxiliary plate can prevent the U-shaped mounting bracket from shifting in the event of bolt failure, thus ensuring safety; the temporary support platform formed by the horizontal auxiliary plate can effectively prevent falling during the disassembly of the diesel engine, thereby reducing operational risks.

[0020] 2. The rotatable auxiliary plate, in conjunction with the lower and upper rotating slots, provides smooth clearance for the lifting and lowering of the U-shaped mounting bracket; the close contact between the horizontal auxiliary plate and the U-shaped mounting bracket and the lower surface provides additional rigid support for the entire structure to enhance stability.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0028] Example

[0029] like Figure 1-4 As shown, an adjustable diesel engine mounting base includes:

[0030] U-shaped base 1: The U-shaped base 1 is the fundamental support component of the entire mounting base. Made of metal, it possesses high strength and rigidity. Its main function is to detachably fix the entire mounting base to the installation position, providing a stable foundation for the subsequent installation of the U-shaped mounting bracket 2 and the diesel engine. Through a reasonable structural design, the U-shaped base 1 can distribute the vibrations and loads generated during diesel engine operation, ensuring the reliability of the installation position.

[0031] U-shaped mounting bracket 2: Also made of metal, the U-shaped mounting bracket 2 is height-adjustable and installed inside the U-shaped base 1, directly supporting the diesel engine. Its core function is to adjust its height according to the installation height requirements of the diesel engine, adapting to different installation scenarios. During adjustment, the U-shaped mounting bracket 2 maintains good stability, preventing the adjustment from affecting the subsequent installation accuracy of the diesel engine.

[0032] Mounting holes 3: There are two types of mounting holes 3. One type is formed along the width direction on both side walls of the U-shaped mounting bracket 2, and the other type is arrayed along the height direction on both side walls of the U-shaped base 1. Mounting holes 3 can be designed as threaded holes or through holes, mainly used to achieve a fixed connection between the U-shaped mounting bracket 2 and the U-shaped base 1. After the U-shaped mounting bracket 2 is adjusted to a suitable height, by inserting bolts or other fasteners into the corresponding mounting holes 3, the U-shaped mounting bracket 2 can be firmly fixed to the U-shaped base 1, preventing displacement during diesel engine operation.

[0033] Auxiliary Plate 4: Multiple auxiliary plates 4 are rotatably installed inside the side walls of the U-shaped base 1. Their key function is to facilitate height adjustment of the U-shaped mounting bracket 2 and provide support during installation by switching between vertical and horizontal positions. When the height of the U-shaped mounting bracket 2 needs adjustment, the auxiliary plate 4 is rotated to a vertical position, providing sufficient space for raising and lowering the U-shaped mounting bracket 2. After the U-shaped mounting bracket 2 is adjusted to the target height, the auxiliary plate 4 is rotated to a horizontal position. At this point, the auxiliary plate 4 extends into the interior of the U-shaped base 1 and abuts against the inner top wall of the U-shaped base 1, providing stable support for the U-shaped mounting bracket 2 and further enhancing the load-bearing capacity of the entire mounting base. Furthermore, when the U-shaped mounting bracket 2 abuts against the upper surface of the horizontal auxiliary plate 4, the mounting holes 3 on the U-shaped mounting bracket 2 correspond one-to-one with the mounting holes 3 on the side wall of the U-shaped base 1, which facilitates subsequent fixed connection operations. After the U-shaped mounting bracket 2 is installed, the auxiliary plate 4 provides auxiliary support for the diesel engine. If the bolts fail or loosen, the engine will not move. At the same time, when the diesel engine needs to be disassembled, it can be supported to prevent it from falling during disassembly, which is beneficial for installation and disassembly operations.

[0034] Lower Rotating Slot 5 and Upper Rotating Slot 6: Both lower rotating slot 5 and upper rotating slot 6 are located within the side walls of the U-shaped base 1, below and above the auxiliary plate 4, respectively. Their depth and width are precisely designed to provide clearance when the auxiliary plate 4 rotates, preventing interference between the auxiliary plate 4 and the side walls of the U-shaped base 1 during rotation, ensuring smooth transitions between vertical and horizontal positions. Simultaneously, the rotation point of the auxiliary plate 4 (achieved through a rotating shaft, the vertical projection of which lies within the upper rotating slot 6) also lies within the upper rotating slot 6. This design further optimizes the rotation trajectory of the auxiliary plate 4, ensuring the reliability of its rotation.

[0035] I. Initial Preparation Before Installation: Before the diesel engine is installed, the base is in an initial standby state: The U-shaped base 1, as the basic support component, is detachably fixed to the installation position through its own adaptation structure (such as bottom fixing holes), providing a stable reference for all subsequent operations; the auxiliary plate 4 is in a vertical state by default. At this time, the lower rotating groove 5 (located below the auxiliary plate 4) and the upper rotating groove 6 (located above the auxiliary plate 4) provide sufficient clearance for the auxiliary plate 4 through precisely designed depth and width, avoiding interference with the side wall of the U-shaped base 1. At the same time, the rotation point (rotation axis) of the auxiliary plate 4 is projected in the upper rotating groove 6 in the vertical direction, ensuring the smoothness of subsequent rotation movements; the U-shaped mounting bracket 2 is height-adjustable and assembled inside the U-shaped base 1. At this time, the height is not locked, and it can be freely raised and lowered along the inner wall of the U-shaped base 1, waiting to be adjusted according to the installation height requirements of the diesel engine.

[0036] II. Diesel Engine Installation Height Adjustment; When it is necessary to adjust the position of the U-shaped mounting bracket 2 according to the diesel engine installation height requirements, the operation revolves around the state transition of the auxiliary plate 4 and the coordination of the lifting and lowering of the U-shaped mounting bracket 2:

[0037] Auxiliary plate 4 adjustment: Since the auxiliary plate 4 is initially vertical, its space will not obstruct the lifting and lowering of the U-shaped mounting bracket 2. The operator can directly push the U-shaped mounting bracket 2 up and down along the inner wall of the U-shaped base 1 until it is adjusted to the target position that matches the installation height of the diesel engine. During this process, the U-shaped base 1, with its high-strength metal structure, always provides stable guidance for the lifting and lowering of the U-shaped mounting bracket 2, avoiding deviation during adjustment and ensuring installation accuracy.

[0038] Auxiliary plate 4 support conversion: After the U-shaped mounting bracket 2 reaches the target height, the operator drives the auxiliary plate 4 to rotate from a vertical to a horizontal position via a pivot. During the rotation, the lower rotating groove 5 and the upper rotating groove 6 continue to play a role in avoiding collisions between the auxiliary plate 4 and the side wall of the U-shaped base 1, ensuring that the auxiliary plate 4 rotates smoothly to the horizontal position. At this time, the horizontal auxiliary plate 4 extends into the interior of the U-shaped base 1, with its lower surface fitting against the internal structure of the side wall of the U-shaped base 1 and its upper surface abutting against the lower surface of the U-shaped mounting bracket 2. At the same time, the mounting holes 3 on the side wall of the U-shaped mounting bracket 2 are precisely aligned with the mounting holes 3 arrayed along the height direction on the side wall of the U-shaped base 1, preparing for subsequent fixing operations.

[0039] III. U-shaped mounting bracket fixing and diesel engine installation; After height adjustment, proceed to the stabilization and fixing stage: The operator inserts bolts or other fasteners into the mounting holes 3 (threaded holes or through holes adapted to the fastener type) aligned with the U-shaped mounting bracket 2 and the U-shaped base 1. Tightening the fasteners achieves a rigid connection between the two, completely locking the height position of the U-shaped mounting bracket 2 and preventing displacement due to vibration or load during diesel engine operation. Subsequently, the diesel engine is hoisted onto the U-shaped mounting bracket 2, utilizing the load-bearing structure of the U-shaped mounting bracket 2 to directly fix the diesel engine. At this point, the U-shaped mounting bracket 2, thanks to the high strength of its metal material, directly bears the weight load of the diesel engine. Simultaneously, the U-shaped base 1, through its load-distributing design, evenly transfers the vibration and pressure generated during diesel engine operation to the installation foundation, further ensuring the overall reliability of the installation.

[0040] IV. The dual protection function of auxiliary plate 4: After the diesel engine is installed and put into use, auxiliary plate 4 provides dual safety protection:

[0041] Bolt failure emergency protection: If the bolts in the mounting hole 3 become loose or fail during long-term use, the horizontal auxiliary plate 4 can provide stable support for the U-shaped mounting bracket 2 by tightly abutting against the lower surface of the U-shaped mounting bracket 2, preventing it from shifting due to loss of bolt fixation, avoiding tilting or deviation of the diesel engine, and ensuring the safe operation of the equipment.

[0042] Anti-fall protection during disassembly: When the diesel engine needs to be disassembled for maintenance, the operator does not need to remove the auxiliary plate 4 first. The horizontal auxiliary plate 4 can be used directly as a temporary support platform. When removing the connection structure between the diesel engine and the U-shaped mounting bracket 2, the auxiliary plate 4 can support the weight of the diesel engine, preventing it from suddenly falling due to loss of fixation during the disassembly process, providing safety for the disassembly operation and reducing operational risks.

[0043] V. Secondary Height Adjustment and Base Reset; If it is necessary to adjust the diesel engine installation height or replace it with a different specification diesel engine in the future, the base can be reset and adjusted secondaryly according to the following procedure: First, remove the fixing bolts between the U-shaped mounting bracket 2 and the U-shaped base 1, and then drive the auxiliary plate 4 from the horizontal state back to the vertical state (the lower rotating groove 5 and the upper rotating groove 6 provide clearance again to ensure smooth rotation). At this time, the U-shaped mounting bracket 2 returns to the lifting state, and the operator can push it again to adjust to the new target height. Repeat the "auxiliary plate 4 horizontal conversion - bolt fixing" process to complete the secondary installation. If it is necessary to remove the entire base, first remove the diesel engine, then remove the U-shaped base 1 from the installation position, and finally reset the auxiliary plate 4 to the vertical state, so that the base returns to the initial standby state for easy storage or transfer.

[0044] The combination of U-shaped base 1, liftable U-shaped mounting bracket 2 and array mounting holes 3 enables precise and stable adjustment of the diesel engine installation height.

[0045] The rotatable auxiliary plate 4, in conjunction with the lower rotating groove 5 and the upper rotating groove 6, provides smooth clearance for the lifting and lowering of the U-shaped mounting bracket 2.

[0046] The horizontal auxiliary plate 4, in close contact with the U-shaped mounting bracket 2 and the lower surface, provides additional rigid support to the entire structure to enhance stability.

[0047] The emergency support surface formed by the horizontal auxiliary plate 4 can prevent the U-shaped mounting bracket 2 from shifting in the event of bolt failure, thus ensuring safety.

[0048] The temporary support platform formed by the horizontal auxiliary plate 4 can effectively prevent the diesel engine from falling during disassembly, thereby reducing operational risks.

[0049] The detachable connection of the U-shaped base 1 and the state reset design of the auxiliary plate 4 enable the entire base to be quickly reset for easy storage and transfer.

[0050] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
