[0002] A skid-mounted compressor is a set of equipment whose various parts are fixed on a common skid made of H-beam or I-beam. It has relatively complete functionality and self-sufficiency. After providing some simple public engineering conditions in the outside world, it can realize the user's gas pressurization function by simply connecting to the outside world with pipelines and cables. It is also the future development direction of compressor equipment due to its compact structure, small footprint, and easy production, installation, and migration. For large skid-mounted compressors, due to their large structural dimensions, the integrated skid does not meet the transportation needs, so the compressor skid is often split into multiple skid bodies, which requires disassembly and transportation as well as on-site reinstallation.

[0003] The large compressor skid includes a main skid and a secondary skid. The main skid is used to install the main part of the compressor, and the secondary skid is used to install the accessories of the compressor (such as pipes, valves, containers, etc.). The current secondary skid is fixed to the main skid by bolts. However, deformation is inevitable during operation or transportation. After deformation, it is difficult to install the bolts, which makes it difficult to smoothly reinstall the compressor. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0030] Example:

[0031] The compressor bottom skid provided in this embodiment can be conveniently adjusted for a large piston compressor. Figure 1-Figure 3 As shown, it includes a main skid body 100, an auxiliary skid body 500, bolts 800 and nuts 900, wherein:

[0032] The main skid 100 is used to install the main part of the compressor (specifically, the body of the compressor). A mounting structure is fixedly connected to the main skid 100, and the mounting structure is provided with a first through hole 400. The auxiliary skid 500 is used to install the accessories of the compressor (such as pipes, valves and containers). A connecting structure is fixedly connected to the auxiliary skid 500, and the connecting structure is provided with a second through hole 700. The bolt 800 passes through the second through hole 700 and the first through hole 400 and is screwed with the nut 900, that is, the stud section of the first bolt 800 passes through the second through hole 700 and the first through hole 400 in sequence to lock the connecting structure on the mounting structure, thereby connecting the auxiliary skid 500 to the main skid 100. The first through hole 400 and / or the second through hole 700 are waist-shaped holes. As an optional implementation of this embodiment, the first through hole 400 in this embodiment is a waist-shaped hole, and the second through hole 700 is a straight hole adapted to the bolt 800. As another optional implementation of this embodiment, the second through hole 700 in this embodiment is a waist-shaped hole, and the first through hole 400 is a straight hole adapted to the bolt 800. As the best implementation of this embodiment, the first through hole 400 and the second through hole 700 in this embodiment are both waist-shaped holes.

[0033] Optionally, the bolt 800 is an external hexagonal bolt 800 .

[0034] During specific use, the main body of the compressor is installed on the main skid body 100, and the accessory part of the compressor is installed on the auxiliary skid body 500, and then the connecting structure is connected to the mounting structure by using the bolts 800 and nuts 900, so that the auxiliary skid body 500 is connected to the main skid body 100. At this time, the main skid body 100 and the auxiliary skid body 500 jointly support the large compressor as a whole. Since the first through hole 400 and / or the second through hole 700 for passing the bolt 800 are waist-shaped holes, even if the main skid body 100 and / or the auxiliary skid body 500 are deformed during operation and transportation, the bolt 800 can still smoothly pass through the above-mentioned connecting structure and mounting structure, thereby facilitating installation, so that the compressor reinstallation process is easier and smoother.

[0035] An optional implementation of this embodiment is as follows: the main pry body 100 is an I-beam composed of a web, an upper wing and a lower wing, and the web of the main pry body 100 is fixed between its upper wing and lower wing. The mounting structure includes a first plate 200 and a second plate 300, wherein the first plate 200 is fixed to the web of the main pry body 100, and one end of the first plate 200 away from the web of the main pry body 100 is flush with the edge of the lower wing of the main pry body 100, and the second plate 300 is fixed between the first plate 200 and the lower wing of the main pry body 100, and the second plate 300 is parallel to the web of the main pry body 100, and a gap is formed between the second plate 300 and the web of the main pry body 100, and the bolt 800 is accommodated in the gap. Optionally, the first plate 200 is welded to the side wall of the web of the main skid 100 , the top of the second plate 300 is welded to one end of the first plate 200 away from the web of the main skid 100 , and the bottom of the second plate 300 is welded to the edge of the lower wing plate of the main skid 100 .

[0036] The first via hole 400 is formed on the second plate 300 , and is a waist-shaped hole. Moreover, the length direction of the first via hole 400 is parallel to the length direction of the main pry body 100 .

[0037] During operation or transportation, if the main pry body 100 or the auxiliary pry body 500 is deformed in the length direction of the main pry body 100, if the first through hole 400 and the second through hole 700 are both straight holes (i.e., non-waist-shaped holes), the deformation will cause the first through hole 400 and the second through hole 700 to be staggered in the length direction of the main pry body 100, and it will be very difficult to install the bolt 800. In this embodiment, the first through hole 400 is set as a waist-shaped hole, and even if the main pry body 100 or the auxiliary pry body 500 is deformed in the length direction of the main pry body 100, the second through hole 700 can still be aligned with the first through hole 400, thereby facilitating the installation of the bolt 800.

[0038] In addition, the auxiliary skid body 500 is an I-beam composed of a web, an upper wing plate and a lower wing plate, and the web of the auxiliary skid body 500 is fixed between its upper wing plate and the lower wing plate. The connection structure includes a third plate 600, which is fixed to one end surface of the auxiliary skid body 500, and the third plate 600 covers one end surface of the auxiliary skid body 500. Specifically, the third plate 600 is welded to one end surface of the auxiliary skid body 500.

[0039] The second via hole 700 is a waist-shaped hole opened on the third board 600 , and the length direction of the second via hole 700 is perpendicular to the length direction of the first via hole 400 . Specifically, the length direction of the second via hole 700 is the height direction of the main pry body 100 .

[0040] During operation or transportation, if the main pry body 100 or the auxiliary pry body 500 is deformed in the height direction of the main pry body 100, if the first through hole 400 and the second through hole 700 are both straight holes (i.e., non-waist-shaped holes), the deformation will cause the first through hole 400 and the second through hole 700 to be staggered in the height direction of the main pry body 100, and it will be very difficult to install the bolt 800. In this embodiment, the second through hole 700 is set as a waist-shaped hole, so that even if the main pry body 100 or the auxiliary pry body 500 is deformed in the height direction of the main pry body 100, the second through hole 700 can still be aligned with the first through hole 400, thereby facilitating the installation of the bolt 800.

[0041] In the compressor bottom skid of the above structure, the first through hole 400 and the second through hole 700 for passing the bolt 800 are both waist-shaped holes, and the length directions of the first through hole 400 and the second through hole 700 are perpendicular. In this way, even if the bottom skid is deformed during the operation or transportation of the compressor, as long as the deformation is not too large, the first through hole 400 and the second through hole 700 have overlapping parts, and the bolt 800 can be easily installed. Moreover, thanks to the fact that the first through hole 400 and the second through hole 700 are both waist-shaped holes, the position of the auxiliary skid can be easily adjusted when it is installed on the main skid, making the compressor assembly more convenient.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
