[0021] Please see Figures 1 to 7 This utility model provides a novel hydraulic lifting device, comprising a fixed frame 10, a telescopic frame 20, a hydraulic cylinder 30, a cylinder pin 40, a cotter pin 50, and a locking nut 60. The lifting frame is movably connected to the fixed frame 10 and is located below the fixed frame 10. The locking nut 60 is fixedly connected to the telescopic frame 20 and is located on the telescopic frame 20. The lower fulcrum of the hydraulic cylinder 30 is movably connected to the locking nut 60. The cotter pin 50 is fixedly connected to the upper fulcrum of the hydraulic cylinder 30 and is located inside the fixed frame 10. The cylinder pin 40 is movably connected to both the fixed frame 10 and the cotter pin 50, and passes through both the fixed frame 10 and the cotter pin 50.

[0022] In this embodiment, the fixed frame 10 and the telescopic frame 20 are assembled into an integrated structure by means of the hydraulic cylinder 30. First, the fixed frame 10 and the telescopic frame 20 are welded together. The telescopic frame 20 has a screw hole corresponding to the lower support point of the hydraulic cylinder 30. The lower support point of the hydraulic cylinder 30 and the telescopic frame 20 are screwed and fixed by the locking nut 60. The upper support point of the hydraulic cylinder 30 and the fixed frame 10 are connected and fixed by the cylinder pin 40 and the cotter pin 50. The above structure is fixed to the side of the main beam of the modified vehicle's Class II chassis. Through reasonable structural design, it meets the lifting and lowering conditions of heavy objects. In addition, the hydraulic cylinder 30 serves as a power source, providing stable and powerful hydraulic power, which greatly improves the load-bearing capacity of heavy objects and avoids insufficient power and unstable lifting. It can meet the lifting and lowering function of large heavy objects.

[0023] Furthermore, the fixing frame 10 includes a top plate 101, a cylinder seat 102, two upper slide rails 103, a reinforcing beam 104, a back plate 105, and two sets of first bearing 107 assemblies. The two upper slide rails 103 are movably connected to the telescopic frame 20. The two ends of the top plate 101 are fixedly connected to the two upper slide rails 103. The cylinder seat 102 is fixedly connected to the top plate 101 and is located below the top plate 101. The two ends of the back plate 105 are fixedly connected to the two upper slide rails 103. The two ends of the reinforcing beam 104 are fixedly connected to the two upper slide rails 103. The two sets of first bearing 107 assemblies are respectively fixedly installed on the inner sidewalls of the corresponding upper slide rails 103.

[0024] In this embodiment, the top plate 101 is fixed above the two upper slide rails 103, the reinforcing beam 104 makes the two upper slide rails 103 more stable, the cotter pin 50 on the upper support point of the hydraulic cylinder 30 is located inside the cylinder seat 102, and the cotter pin 50 is used to fix the upper support point of the hydraulic cylinder 30 on the top plate 101. As the hydraulic cylinder 30 extends and retracts, the telescopic frame 20 will rise and fall between the two upper slide rails 103.

[0025] Furthermore, the first bearing 107 assembly includes a first slider 106, a first bearing 107, and a plurality of first bolts 108. The first slider 106 is located within the upper slide rail 103. The plurality of first bolts 108 all movably pass through the upper slide rail 103 and are threadedly connected to the first slider 106.

[0026] In this embodiment, the first bearing 107 assembly consists of the first slider 106, the first bearing 107 and the first bolt 108. The first slider 106 is fastened to the sliding track 204 by the first bolt 108. As the hydraulic cylinder 30 extends and retracts, the first bearing 107 slides in the telescopic frame 20, facilitating the movement of the telescopic frame 20 and the fixed frame 10.

[0027] Furthermore, the telescopic frame 20 includes a support plate 201, a plurality of first reinforcing ribs 202, a plurality of second reinforcing ribs 203, two sliding tracks 204, and two sets of second bearing assemblies 205.

[0028] In this embodiment, the lower slide 204 is movable relative to the upper slide 204. The arrangement of the first bearing 107 assembly and the second bearing 205 assembly makes the lifting and lowering movement of the lower slide 204 smoother. The support plate 201 is fixed below the two lower slides 204. Multiple first reinforcing ribs 202 and multiple second reinforcing ribs 203 make the two upper slides 103 fixed and stable above the support plate 201. The lower fulcrum of the hydraulic cylinder 30 is screwed and fixed on the support plate 201 by the locking nut 60. As the hydraulic cylinder 30 extends and retracts, the two lower slides 204 will slide on the upper slides 103 respectively, and then the support plate 201 is driven to rise and fall.

[0029] Furthermore, the second bearing 205 assembly includes a second slider 207, a second bearing 205, and a plurality of second bolts 206. The second slider 207 is located within the lower slide 204, and the plurality of second bolts 206 all movably pass through the lower slide 204 and are threadedly connected to the second slider 207.
