[0002] With the increasing energy demand and optimization of my country's energy structure, distributed energy generation, as an emerging energy development model, has received widespread attention. Based on this, micro-gas turbines are being further promoted for power generation applications involving the recovery of associated gas in offshore oil and gas fields.

[0003] Miniature gas turbines offer advantages such as low cost, high reliability, and high flexibility, enabling them to adapt to various working environments and needs. However, the variability of their operating scenarios also presents some maintenance challenges. Large lifting equipment, such as overhead cranes, cannot access confined or specialized workspaces, or operating in such environments is extremely inconvenient. Furthermore, the high cost of using large lifting equipment makes the hoisting and maintenance of the core components of miniature gas turbines particularly difficult.

[0004] Due to their small size and weight, miniature gas turbines typically require specific tools and techniques for hoisting and moving. In the absence of suitable lifting equipment, workers are forced to rely on makeshift tools for transport, which not only increases the difficulty of the operation but also significantly raises safety risks.

[0005] Therefore, there is an urgent need for a new sliding device for micro gas turbines to solve the above-mentioned technical problems. Utility Model Content

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to address the difficulties in hoisting and maintaining the core unit of micro-gas turbines when they are used in small or special working spaces, where large lifting equipment such as overhead cranes cannot enter or are very inconvenient to operate in such environments. In addition, in the absence of appropriate lifting equipment, workers can only rely on simple tools for transportation, which not only increases the difficulty of operation but also greatly increases the safety risks.

[0007] To this end, the present invention provides a sliding device for a micro gas turbine, the micro gas turbine including a gearbox, a core engine, a gearbox base, and a machine base. The core engine is fixedly connected to the gearbox, the gearbox is fixed on the gearbox base, and the gearbox base is detachably fixedly connected to the machine base. The sliding device includes a support frame, a slide rail, a sliding frame, and at least two lifting bolts. One end of the slide rail is detachably fixedly connected to the support frame, and the other end of the slide rail can be detachably fixedly connected to the machine base when lifting and sliding the gearbox and core engine. The sliding frame is disposed on the slide rail and can be detachably fixedly connected to the gearbox base. The sliding frame is configured to move along the track of the slide rail. The lifting bolts can be threadedly connected to a pre-drilled lifting threaded hole on the gearbox base to lift the gearbox base by rotating the lifting bolts.

[0008] In a specific embodiment of the sliding device for the micro gas turbine described above, the sliding frame includes two frames, which are detachably and fixedly connected to both ends of the gearbox base during lifting and sliding.

Each end of the spreader beam is fixed with a swivel caster that cooperates with the slide rail. The spreader beam is detachably and fixedly connected to the gearbox base.

[0010] In a specific embodiment of the sliding device for the aforementioned micro gas turbine, the spreader beam is detachably and fixedly connected to the gearbox base by fastening bolts.

[0011] In a specific embodiment of the sliding device for the aforementioned micro gas turbine, the sliding rail includes two spaced and parallel sliding tracks. The other ends of the two sliding tracks can pass through the gearbox and the gearbox base to be detachably and fixedly connected to the engine base. The center line of the spreader beam in the length direction is perpendicular to the center line of the sliding track in the length direction. Each caster wheel is equipped with one of the sliding tracks so that it can travel along the trajectory of the sliding track.

[0012] In a specific embodiment of the sliding device for the aforementioned micro gas turbine, the support frame includes two crossbeams and four telescopic longitudinal beams. Each crossbeam has a longitudinal beam fixedly connected to its bottom ends. The two crossbeams are arranged along the trajectory of the slide rail and are both fixedly connected to one end of the slide rail.

[0026] This utility model relates to the field of micro gas turbine maintenance technology, and in particular to a sliding device for micro gas turbines. The purpose is to solve the problem that existing micro gas turbines, when used in confined or special working spaces, face difficulties in hoisting and maintaining the core unit due to the inability of large lifting equipment such as overhead cranes to enter, or the significant inconvenience of operation in such environments. Furthermore, in the absence of suitable lifting equipment, workers are forced to rely on simple tools for handling, which not only increases the difficulty of the work but also greatly increases safety risks. To this end, the sliding device for micro gas turbines provided by this utility model includes a support frame, a slide rail, a sliding frame, and at least two lifting bolts. One end of the slide rail is detachably fixed to the support frame, and the other end of the slide rail can be detachably fixed to the turbine base when lifting and sliding the gearbox and core unit. The sliding frame is mounted on the slide rail and can be detachably fixed to the gearbox base. The sliding frame is designed to move along the track of the slide rail.

The sliding device designed in this utility model can use lifting bolts to lift the gearbox base and connect it to the sliding frame, so that the gearbox and core machine can move freely along the sliding track with the sliding frame. Because it relies on the sliding track for support and the universal casters for movement, it reduces the difficulty of operation and the labor intensity of manual handling with simple tools, and improves safety. At the same time, it can move the gearbox and core machine without the need for cranes or other lifting equipment, reducing the initial investment cost. The sliding device has a simple overall structure, low manufacturing cost, and good applicability and flexibility.

[0027] The sliding device for a micro gas turbine provided in the embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] See Figure 1-3 This utility model provides a sliding device for a micro gas turbine. The micro gas turbine includes a gearbox 7, a core engine 6, a gearbox base 9, and a turbine base 8. The core engine 6 is fixedly connected to the gearbox 7, and the gearbox 7 is fixed on the gearbox base 9. The gearbox base 9 is detachably fixedly connected to the turbine base 8. The sliding device includes a support frame, a slide rail, a sliding frame, and at least two lifting bolts 5. One end of the slide rail is detachably fixedly connected to the support frame, and the other end of the slide rail can be detachably fixedly connected to the turbine base 8 when lifting and sliding the gearbox 7 and the core engine 6. The sliding frame is set on the slide rail and can be detachably fixedly connected to the gearbox base 9. The sliding frame is configured to move along the track of the slide rail. The lifting bolts 5 can be threadedly connected to the lifting threaded holes pre-drilled on the gearbox base 9 to lift the gearbox base 9 by rotating the lifting bolts 5.

[0029] In one embodiment, see below. Figure 1-2The sliding frame includes two frames 4, which are detachably and fixedly connected to both ends of the gearbox base 9 during lifting and sliding.

[0030] In the above embodiment, preferably, the frame 4 includes a spreader beam 401 and two swivel casters 402. Each end of the spreader beam 401 is fixed with a swivel caster 402 that cooperates with the slide rail. The spreader beam 401 is detachably and fixedly connected to the gearbox base 9.

[0031] Specifically, the spreader beam 401 is detachably and fixedly connected to the gearbox base 9 by fastening bolts 403. Two first threaded holes are provided along the length of the spreader beam 401, each equipped with a fastening bolt 403. The gearbox base 9 has pre-drilled second threaded holes that match the first threaded holes. When the gearbox base 9 is lifted to the height matching the spreader beam 401, the spreader beam 401 is inserted under the end of the gearbox base 9, and the fastening bolts 403 are inserted into the first and second threaded holes to achieve a detachable and fixed connection. Since the swivel casters 402 can move along the slide rails, the gearbox 7 and the core machine 6 can move freely along the slide rails under manual drive, following the gearbox base 9. The swivel casters 402 reduce friction, lower the labor intensity of manual pushing, and save time and effort.

[0032] In the above embodiments, preferably, the number of lifting bolts 5 is even, that is, the number of lifting bolts 5 is two or four, etc. Figure 1 As shown, there are four lifting bolts 5, distributed at the four corners of the gearbox base 9. The gearbox base 9 has pre-drilled lifting threaded holes that mate with the lifting bolts 5, allowing the lifting bolts 5 to be directly inserted into these holes during subsequent maintenance. By rotating the lifting bolts 5, the gearbox base 9 can be lifted, thereby lifting the gearbox 7 and the core machine 6.

[0033] The specific working process of the lifting bolts 5 is as follows: all lifting bolts 5 are screwed into the corresponding lifting threaded holes. As the screwing depth increases, the lifting bolts 5 gradually extend out of the gearbox base 9 and abut against the machine base 8, applying a thrust to the machine base 8. At this time, the core machine 6 and gearbox 7 are subjected to a reaction force and are thus lifted until the core machine 6 and gearbox 7 are lifted as a whole to the height that allows the spreader beam 401 to be inserted and assembled. During the screwing process, care should be taken to keep the core machine 6 and gearbox 7 in a horizontal state to avoid tipping over. For example, the lifting situation can be observed with a spirit level, and adjustments can be made in time if any deviation occurs. Alternatively, the parallelism between the gearbox 7 and the gearbox base 9 can be measured every five threads screwed in, and adjustments can be made in time if any deviation occurs.

[0034] In the above embodiments, preferably, as follows: Figure 1-3As shown, the support frame includes two crossbeams 2 and four telescopic longitudinal beams 1. Each crossbeam 2 has a longitudinal beam 1 fixedly connected to its bottom ends. The two crossbeams 2 are arranged along the track direction of the slide rail and are both fixedly connected to one end of the slide rail. The longitudinal beams 1 are used to fix the frame to the ground.

[0035] Specifically, the longitudinal beam 1 includes an upper beam and a lower beam nested together. The lower beam has two vertically arranged lower limit holes on its side wall, and the upper beam has multiple vertically arranged upper limit holes 10 on its side wall. Each lower limit hole is aligned with one of the upper limit holes 10, and a limit bolt 11 is inserted to limit the position of the upper beam. By inserting the limit bolt 11 into different upper limit holes 10, the height of the longitudinal beam 1 can be adjusted, thereby adjusting the height of the crossbeam 2. This allows the height of the support frame to be adjusted according to different heights of the machine base 8, ensuring that the slide rail remains horizontal after its other end is detachably and fixedly connected to the machine base 8, providing good adaptability. After insertion, the limit bolt 11 connects with a limit nut to lock its position.

[0036] In the above embodiment, preferably, the slide rail includes two spaced and parallel sliding tracks 3, the other end of the two sliding tracks 3 can pass through the gearbox 7 and the gearbox base 9 to be detachably and fixedly connected to the machine base 8, the center line of the spreader beam 401 in the length direction is perpendicular to the center line of the sliding track 3 in the length direction, and each universal wheel is equipped with a sliding track 3 so that it can travel along the trajectory of the sliding track 3.

[0037] The sliding track 3 is designed to ensure that the core machine 6 and gearbox 7 can move along a precise path and direction, avoiding any possible deviations or misalignments. Operators push or pull the core machine 6 and gearbox 7 freely along the sliding track 3 according to the predetermined operating procedures. To ensure the stability and safety of the sliding track 3, its other end is bolted to the machine base 8.

[0038] In addition, such as Figure 4 As shown, since the gearbox 7 and core engine 6 of the micro gas turbine are enclosed by the housing 12, and the housing 12 is equipped with a door that allows the gearbox 7 and core engine 6 to pass through, in the prior art, operators need to remove the housing 12 from the base 8 to lift the gearbox 7 and core engine 6, which is very inconvenient. In this application, however, it is only necessary to insert the sliding rail 3 into the housing 12 from the door position and fix it to the base 8. Then, the gearbox 7 and core engine 6 are lifted from inside the housing 12 to connect the gearbox base 9 with the sliding frame. This allows the gearbox 7 and core engine 6 to be moved out of the housing 12 along the sliding rail 3 without removing the housing 12. By omitting the step of removing the housing 12, the operation is greatly simplified.

[0039] The working principle of this utility model is as follows: First, the other end of the sliding track 3 is passed through the bottom of the gearbox 7 and fixed to the base 8. The two frames 4 are located on both sides of the gearbox base 9. Then, the lifting bolt 5 is screwed into the lifting threaded hole of the gearbox base 9. As the lifting bolt 5 is continuously screwed in, the gearbox base 9 drives the core machine 6 and the gearbox 7 to be slowly lifted until the core machine 6 and the gearbox 7 are lifted as a whole to the height that allows the spreader beam 401 to be inserted and assembled. Then, the spreader beam 401 is inserted into the bottom of the gearbox 7 and the spreader beam 401 is connected to the gearbox base 9 by the fastening bolt 403. After the connection is completed, the lifting bolt 5 is slowly loosened until the universal caster 402 is fully engaged with the sliding track 3. Then the lifting bolt 5 is removed, and the gearbox 7 and the core machine 6 can be moved along the sliding track 3 under manual traction.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
