By setting up the lifting structure 3, the overall hoisting and transportation of the equipment is facilitated. The lifting structure includes a support base 31, a locking structure 32, and a lifting component 33. The support base 31 provides a support point for the lifting component 33. The locking structure 32 is used to firmly connect the lifting component 33 to the support base 31 to ensure that it will not fall off or loosen during the hoisting process, thus ensuring the stability of the hoisting process. At the same time, the lifting component 33 can be replaced according to different situations. The lifting component 33 is used in conjunction with the crane to facilitate the overall hoisting of the equipment.

[0029] As a preferred embodiment of this utility model, it may also have the following additional technical features: the support base 31 includes a support plate 311 and two upright blocks 312. Two upright blocks 312 are respectively disposed at both ends of the support plate 311 and fixedly connected to the support plate 311. Each upright block 312 has a positioning hole 3121. The bottom pry bar 1 is fixedly connected to the two upright blocks 312 through the positioning hole 3121 via a locking member. In this embodiment, the support plate 311 and the two upright blocks 312 are vertically arranged, improving the stability of the overall structure. The positioning hole 3121 on the upright block 312 provides a precise positioning point for the connection between the bottom pry bar 1 and the support base 31, ensuring that the support base 31 can be accurately placed on the bottom pry bar 1 and firmly fixed by a locking member, which uses bolts and nuts for fixing.

[0030] As a preferred embodiment of this utility model, it may also have the following additional technical features: the upright block 312 includes a side plate 3122 and a positioning plate 3123. One end of the side plate 3122 is fixedly connected to the support plate 311, and the end of the side plate 3122 away from the support plate 311 is bent and connected to the positioning plate 3123, increasing the vertical support area of ​​the upright block 312 and making the force-bearing surface of the upright block 312 larger, thereby improving the stability of the overall structure. The positioning hole 3121 is set in the center of the positioning plate 3123, ensuring that the locking elements can be evenly distributed on the upright block 312, thereby providing a more balanced support force. The size and shape of the positioning hole 3121 are usually customized according to the type and size of the locking elements to ensure the strength and reliability of the connection point.

By rotating the rotating screw 321 clockwise, the lifting component 33 can be quickly installed on the support frame; when the lifting component 33 is worn or damaged, rotating the rotating screw 321 counterclockwise allows the lifting component 33 to be quickly disassembled and replaced without replacing the entire lifting structure 3, thus reducing equipment maintenance costs.

[0033] As a preferred embodiment of this utility model, it may also have the following additional technical features: a protective shell 34 is provided at the bottom of the support base 31, the protective shell 34 is fixedly connected to the support base 31, and the rotating nut 322 is located inside the protective shell 34 to protect the internal rotating nut 322, which helps to prevent moisture, dust, debris and other impurities from entering and damaging the locking structure 32, and avoids the support base 31 from becoming loose.

[0034] As a preferred embodiment of this utility model, it may also have the following additional technical features: the lifting component 33 includes a hook portion 331, a connecting portion 332, and a mounting portion 333, which are connected sequentially. The mounting portion 333 is detachably connected to the support base 31 via a locking structure 32.

The detachable connection between the mounting portion 333 and the support base 31 simplifies equipment maintenance. Users can easily disassemble the lifting component 33 for inspection, repair, or replacement as needed, thereby reducing maintenance costs and improving equipment availability.

[0035] As a preferred embodiment of this utility model, it may also have the following additional technical features: the lifting component 33 includes a locking screw 334, a locking screw hole is provided on the connecting part 332, and a hook tip 3311 is provided on the hook part 331. The locking screw 334 can pass through the locking screw hole and move towards the hook tip 3311. When the lifting ring of the crane hooks onto the hook part 331, it is fixed by the locking screw 334, making the connection between the lifting ring of the crane and the lifting component 33 more stable and the lifting safer. The hook part 331 is provided with anti-slip protrusions 3312, which further enhances the connection stability between the lifting component 33 and the object being lifted.

[0036] As a preferred embodiment of this utility model, it may also have the following additional technical features: The hydrogen compressor 2 includes a first hydrogen delivery pipe 21, a second hydrogen delivery pipe 22, a compression device 23, and a cooling component 24. The compression device 23 and the cooling component 24 are respectively mounted on the skid 1 and fixedly connected to the skid 1. The compression device 23 is connected to the first hydrogen delivery pipe 21 and is used to compress the hydrogen introduced into the hydrogen delivery pipe and introduce the compressed hydrogen into the second hydrogen delivery pipe 22. The cooling component 24 is connected to the second hydrogen delivery pipe 22 and is used to cool the hydrogen in the second hydrogen delivery pipe 22. In this embodiment, a portion of the second hydrogen delivery pipe 22 is disposed inside the cooling component 24. Hydrogen enters the compression device 23 from the first hydrogen delivery pipe 21. After being compressed by the compressor, its pressure and density increase, and it then enters the second hydrogen delivery pipe 22. In the cooling component 24, the compressed hydrogen exchanges heat with the cooling medium, thereby reducing its temperature and pressure.

[0037] As a preferred embodiment of this utility model, it may also have the following additional technical features: the compression device 23 includes a hydraulic component 231, a compression component 232, and a hydraulic pipeline 233. The hydraulic component 231 is connected to the first hydrogen delivery pipe 21, and the hydraulic component 231 is connected to the compression component 232 through the hydraulic pipeline 233. The compression component 232 introduces hydrogen into the second hydrogen delivery pipe 22. In this embodiment, the hydraulic component 231 includes a hydraulic support 2311, a hydraulic oil tank 2312, and a hydraulic pump 2313. The hydraulic oil tank 2312 is mounted on the hydraulic support 2311, and the hydraulic pump 2313 is mounted below the hydraulic oil tank 2312. The compression component 232 includes a hydraulic cylinder 2321, and the hydraulic cylinder 2321 is connected to the hydraulic pump 2313 through the hydraulic pipeline 233. Thus, hydraulic oil from the hydraulic oil tank 2312 is pumped by hydraulic pump 2313 to hydraulic cylinder 2321. Hydraulic cylinder 2321 compresses hydrogen gas via piston rod and introduces the hydrogen gas into the second hydrogen delivery pipe 22. Cooling component 24 includes an inlet pipe, a cooling pipe, and an outlet pipe connected in sequence; the second hydrogen delivery pipe 22 is located inside the cooling pipe. Cooling water is then pumped from the inlet pipe into the cooling pipe by a water pump. The flowing cooling water quickly removes the heat generated by the compression of the hydrogen gas in the second hydrogen delivery pipe 22, thereby carrying the heat away with the flowing water from the outlet pipe.

[0038] The skid-mounted hydrogen compressor in this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the skid-mounted hydrogen compressor is easy to move when the equipment needs to be transferred, and it is easy to lift and transfer, thereby improving transfer efficiency and reducing operation difficulty and cost.
