Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, specifically relating to a mobile device for large diesel engines, which is particularly suitable for the smooth and safe movement of large diesel engines in confined spaces or indoor environments. Background Technology

[0002] Large diesel engines are widely used in shipbuilding, nuclear power, and power generation. Their large size and heavy weight make them extremely inconvenient to move and install. Currently, the movement of large diesel engines typically relies on heavy equipment such as cranes or overhead cranes, but these are often unusable in confined spaces or indoor environments. In such cases, movement must be carried out manually or using other temporary measures, which is not only complex and inefficient, wasting time and manpower, but also poses safety hazards such as damage to the diesel engine and injuries to personnel.

[0003] While some mobile devices exist in the existing technology, most are complex in structure, lack adaptability, and cannot meet the mobility needs of different environments. Therefore, there is an urgent need for a large diesel engine mobile device that is simple in structure, easy to operate, and has a wide range of applications. Utility Model Content

[0018] Please see Figure 1-11 The embodiments of this utility model are described in detail below.

[0019] Example: See Figure 1 and 2 As shown, a moving device for a large diesel engine includes a track 1, a bracket 3, a jack 4, and a jack support 5.

[0020] See Figure 1 As shown, multiple track segments 1 can be connected to extend the track. Adjacent track segments 1 are connected together by track connectors 2, which are detachable and can connect multiple track segments 1 according to actual needs to adapt to different length movement requirements, thus having a wide range of applications.

[0021] For details, please refer to Figure 3-6 As shown, each section of the track 1 has cylindrical protrusions 1-2 at both ends for connection with the track connector 2. The track connector 2 has connecting holes 2-1 at both ends that are adapted to the cylindrical protrusions 1-2. The connecting holes at both ends of the track connector 2 connect with the cylindrical protrusions 1-2 at the corresponding ends of the two track sections, connecting the two track sections together.

[0022] See Figure 1 , 7 As shown in Figure 8, the bracket 3 is slidably mounted on the track 1 to support the diesel engine. Multiple pads 1-3 are spaced apart on the track 1 to support the bracket 3.

[0023] The jack 4 is fixedly mounted on the bracket 3. Preferably, the jack 4 is a hydraulic jack or a mechanical jack.

[0024] See Figure 1 As shown, the jack support 5 is placed on the track 1, and the middle part of the jack support 5 is connected to the jack 4. The jack support 5 is provided with locking devices 5-3 on both sides, and the track 1 is provided with multiple protrusions 1-1 arranged at intervals on both sides. The locking devices 5-3 can engage or disengage with the protrusions 1-1 on both sides of the track 1.

[0025] For details, please refer to Figure 9-11 As shown, the jack support 5 includes a support plate 5-1, which is placed on the rail surface of the track 1. A jack connecting seat 5-2 is provided in the middle of the upper part of the support plate 5-1. The jack 4 is hinged to the jack connecting seat 5-2. Locking devices 5-3 are provided on both sides of the support plate 5-1.

[0026] The locking device 5-3 includes a locking seat 5-3-1, a locking pin 5-3-2, and a locking plate 5-3-3. The locking seat 5-3-1 is fixed on the support plate 5-1. The locking plate 5-3-3 is hinged to the locking seat 5-3-1 via the locking pin 5-3-2. The locking seat 5-3-1 is provided with a limiting plate 5-3-4 for limiting the rotation angle of the locking plate 5-3-3. The limiting plate ensures that the locking plate 5-3-3 can rotate through the protrusion when it moves with the jack support, and prevents it from rotating when engaged with the protrusion.

[0027] Preferably, the protrusion 1-1 is a T-shaped block structure, and the locking plate 5-3-3 is an L-shaped plate structure that can be adapted and engaged with the T-shaped protrusion 1-1. The inner side of the locking plate 5-3-3 is provided with an arc-shaped structure, so that the jack support 5 can smoothly pass through the protrusions 1-1 on both sides of the track 1 when depressurization is performed.

[0028] The arc-shaped design of the locking device in this embodiment ensures smooth movement and improves work efficiency.

[0029] Working principle of this utility model: 1. In the initial state, the locking device 5-3 engages with the protrusion 1-1 on the track 1, and the jack 4 is in a depressurized state.

[0030] 2. Apply pressure to jack 4. Due to the locking action of locking device 5-3, jack 4 pushes bracket 3 to move along track 1, thereby driving the diesel engine to move.

[0031] 3. When jack 4 reaches its maximum stroke, pressure is released. At this time, due to the large weight of the diesel engine on support 3, the friction between it and rail 1 is greater than the friction between jack support 5 and rail 1. Jack 4 drives jack support 5 to move towards support 3. Due to the arc-shaped design of locking device 5-3, jack support 5 can smoothly pass through protrusion 1-1.

[0032] 4. After jack 4 has depressurized, jack support 5 moves to the next protrusion 1-1 position, and locking device 5-3 engages again. Repeat the above process to achieve continuous movement of the diesel engine.

[0033] This invention utilizes the pressurization and depressurization process of a jack, using the jack's stroke to move the diesel engine. It incorporates a matching track and support system, and a locking device to ensure the jack's reciprocating motion, thereby moving the diesel engine to a predetermined position. The structure is simple, operation is convenient, and it effectively solves the problem of moving large diesel engines in confined spaces or indoor environments. Furthermore, this device achieves smooth movement of the diesel engine through the reciprocating motion of the jack, avoiding the safety hazards of manual handling.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
