Description

Technical Field

[0001] The present invention relates to the technical field of gas turbine engines, and in particular to a gas turbine engine moving method and a slide rail auxiliary connection device. Background Art

[0002] The large gas turbine engines used on offshore oil platforms are large in size and weight, so they must be Figure 1 The slide rail system shown includes an outer cross beam 20 of the pry, pile legs 30, an inner sliding beam 40 of the pry and a guide rail 50. The inner sliding beam 40 of the pry is fixed on the pry block 10, and the outer sliding beam 20 of the pry is arranged on the outside of the pry block 10. The pile legs 30 are fixed to the bottom end of the outer cross beam 20 of the pry for supporting the outer cross beam 20 of the pry, and the guide rail 50 is installed on the top of the outer cross beam 20 of the pry and the inner cross beam 40 of the pry.

[0003] When the slide rail system is used on the land platform to replace the gas turbine engine, the gas turbine engine sits on the slide rail system and slides away from the skid 10. After leaving the skid 10, the gas turbine engine is directly hoisted and transported using an external crane. However, on the offshore oil platform, the equipment is highly concentrated, and the gas turbine engine group installation position cannot be hoisted and transported using a crane. Therefore, the following method is generally used for hoisting and transport: after the gas turbine engine leaves the skid 10 along the sliding system 20, the gas turbine engine is first hoisted and separated from the slide rail system by a hoist above, and then the skid outer beam 20, pile leg 30 and guide rail 50 are removed online; then the transfer vehicle is pushed to the bottom of the gas turbine engine, and the gas turbine engine is lowered and fixed to the transfer vehicle using a hoist, and finally transported. The installation of the gas turbine engine is the reverse process of the removal of the gas turbine engine. In this method, the skid outer beam 20, pile leg 30 and guide rail 50 need to be disassembled and assembled online twice, the process is complicated, and it takes a long time, resulting in an increased risk of the gas turbine engine falling and injuring people when it is in a hoisted state during online disassembly. The outer cross beam 20, pile legs 30 and guide rails 50 of the pry are heavy and difficult to move. They must be hoisted and transported by a transfer vehicle, which is time-consuming and labor-intensive. In addition, after the outer cross beam 20, pile legs 30 and guide rails 50 of the pry are disassembled, it is difficult to reinstall them according to the original spatial position, and the front and rear installation errors will cause the gas turbine engine to shift in position after entering the pry block 10, resulting in subsequent installation difficulties. Summary of the invention

[0048] like Figure 2 As shown, this embodiment provides a gas turbine engine moving method for replacing a gas turbine engine, comprising the following steps:

[0049] Step 1: Install the slide rail system;

[0050] Step 2: Install a slide rail auxiliary connecting device under each skid outer beam 20 of the slide rail system. The slide rail auxiliary connecting device is arranged one-to-one with the skid outer beam 20. The slide rail auxiliary connecting device is fixedly connected to each pile leg 30 under the skid outer beam 20, so that each skid outer beam 20 forms a slide rail beam assembly with the pile leg 30 and the slide rail auxiliary connecting device under it.

[0051] Step 3, slide the old gas turbine engine along the guide rail 50 on the top of the outer cross beam 20 of the pry to the outside of the pry, and use a hoist to lift the old gas turbine engine;

[0052] Step 4, remove the guide rails 50 on the top of each pry outer beam 20;

[0053] Step 5: Use a hydraulic forklift to move each slide beam assembly away from under the old gas turbine engine.

[0054] Step 6: Place the old gas turbine engine on a transfer vehicle and move it out of the work area;

[0055] Step 7: Use a transfer vehicle to transfer the new gas turbine engine to a set position outside the skid, and use a hoist to lift the new gas turbine engine;

[0057] Step 9: Install the guide rail 50 on the top of each skid outer beam 20;

[0058] Step 10, placing the new gas turbine engine on the slide rail system, and sliding along the guide rail 50 into the skid 10;

[0059] Step 11: Remove each slide beam assembly.

[0060] The gas turbine engine moving method provided in this embodiment is to fix a slide rail auxiliary connecting device on the pile leg 30 below the outer cross beam 20 of the pry, so that each outer cross beam 20 of the pry forms a slide beam assembly with the pile leg 30 and the slide rail auxiliary connecting device thereunder. Therefore, after the old gas turbine engine is removed from the pry, each slide beam assembly can be moved as a whole by a hydraulic forklift, avoiding the disassembly and installation of the outer cross beam 20 of the pry and the pile leg 30 thereunder, saving operation time, and avoiding front and rear installation errors.

[0061] Specifically, in this embodiment, the slide rail system includes three skid outer beams 20, three slide rail auxiliary connection devices are provided, two pile legs 30 are provided under each skid outer beam 20, the top of the pile legs 30 are fixed to the beam 20 by bolts, a slide rail auxiliary connection device is provided under each skid outer beam 20, and the two ends of the slide rail auxiliary connection device are respectively fixed to the two pile legs 30 by bolts, and the three skid outer beams 20 and the pile legs 30 and slide rail auxiliary connection devices form three slideway beam assemblies. When the slideway beam assembly is transported by a hydraulic forklift, the three slideway beam assemblies need to be transported separately in three times.

[0062] Optionally, between step 4 and step 5, the following steps are also included:

[0063] Step N, remove the bolts between the pile legs 30 and the ground. In this embodiment, in order to ensure the stability of the pile legs 30, bolts are set between the pile legs 30 and the ground. Before transporting each slideway beam assembly, the bolts between the pile legs 30 and the ground are removed so that the slideway beam assembly can be transported as a whole.

[0064] Optionally, between step 4 and step 5, the following steps are further included:

[0065] Step M, installing a temporary support at the bottom of the old gas turbine engine to support the old gas turbine engine;

[0066] Between step 9 and step 10, it also includes:

[0067] Step F: Install temporary supports at the bottom of the new gas turbine engine to support the new gas turbine engine.

[0068] After the old gas turbine engine and the new gas turbine engine are lifted by the hoist, temporary supports are installed at their bottom to prevent the weight of the old gas turbine engine and the new gas turbine engine from being completely borne by the hoist for a long time, thereby preventing the gas turbine engine from falling and causing an accident.

[0069] Optionally, the temporary support includes a wooden plank and a hydraulic jacking device, the wooden plank is arranged on the ground, and the hydraulic jacking device is arranged on the wooden plank. After the wooden plank is supported, the hydraulic jacking device is placed on it, and the hydraulic jacking device is gradually lifted so that part of the weight of the gas turbine engine is supported by the temporary support device. Specifically, in this embodiment, the hydraulic jacking device is a jack.

[0070] Optionally, step 5 specifically includes the following steps:

[0071] Step 51, move the hydraulic forklift so that the fork of the hydraulic forklift extends under the connecting device, and lift the slide beam assembly through the connecting device;

[0072] Step 52, moving a hydraulic forklift to transfer the slide beam assembly away from under the old gas turbine engine;

[0073] Step 53, repeat steps 51 and 52 to complete the transfer of each slide beam assembly.

[0074] The present embodiment further provides a slide rail auxiliary connection device, which is used in the above-mentioned gas turbine engine moving method, and includes a first crossbeam 1, which is arranged below the skid outer crossbeam 20 of the slide rail system, and the two ends of the first crossbeam 1 are respectively fixedly connected to two pile legs 30 below the skid outer crossbeam 20. Specifically, in the present embodiment, the first crossbeam 1 and the pile legs 30 are detachably connected by bolts.

[0075] like Figure 3 As shown, the slide rail auxiliary connection device provided in this embodiment, by setting a first crossbeam 1 to connect the two pile legs 30 below the outer crossbeam 20 of the pry, so that the outer crossbeam 20 of the pry and the pile legs 30 thereunder and the slide rail auxiliary connection device form a slide beam assembly. After the old gas turbine engine is removed from the pry, the slide beam assembly is lifted by acting on the first crossbeam 1 through a hydraulic forklift, thereby moving the slide beam assembly as a whole, avoiding the disassembly and installation of the outer crossbeam 20 of the pry and the pile legs 30 thereunder, saving operation time, and avoiding front and rear installation errors.

[0076] Optionally, the slide rail auxiliary connection device provided in this embodiment further includes a plurality of second beams 2, which are fixedly arranged at intervals along the length direction of the first beam 1 at the bottom end of the first beam 1, and the second beams 2 are arranged perpendicular to the first beam 1. Specifically, two second beams 2 are provided, and the two second beams 2 are symmetrically arranged at the two ends of the first beam 1, and the distance between the two second beams 2 is the same as the distance between the two forks of the hydraulic forklift. In this embodiment, the distances between the two second beams 2 and the two ends of the first beam 1 are both equal to one third of the length of the first beam 1. By fixing the second beam 2 below the first beam 1, when the hydraulic forklift is used to lift and move the slide beam assembly, the lifting force of the hydraulic forklift acts on the first beam 1 through the second beam 2. Compared with the hydraulic forklift's fork acting directly on the first beam 1, the two forks act on the two second beams 2 respectively, which enables the hydraulic forklift to lift and move the slide beam assembly more stably.

[0077] Optionally, the slide rail auxiliary connection device provided in this embodiment further includes a support leg 3 fixed to the bottom end of the second beam 2, and both ends of the second beam 2 are provided with a support leg 3. By providing the support leg 3, the overall height of the slide rail auxiliary connection device can be increased, thereby reducing the requirement for the lifting height of the hydraulic forklift fork.
