[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1-Figure 5 , the present utility model provides a technical solution:

[0022] A short-distance handling device for large hydraulic cylinder parts, including a U-shaped base 1 with moving auxiliary wheels. A support frame 2 is fixedly installed on the upper surface of the U-shaped base 1. A lifting device 3 is hoisted and installed inside the support frame 2. A lifting tool 4 is detachably connected below the lifting device 3. The lifting tool 4 includes an arc-shaped clamping block A41 and an arc-shaped clamping block B42. The arc-shaped clamping block A41 and the arc-shaped clamping block B42 are detachably connected, and a plurality of "cross" shaped lifting blocks 43 are equidistantly slidably arranged on the upper surfaces of the arc-shaped clamping block A41 and the arc-shaped clamping block B42. Tightening blocks 44 are fixedly installed at the inner ends of the "cross" shaped lifting blocks 43. Adjusting devices 6 are rotatably installed between the arc-shaped clamping block A41 and the arc-shaped clamping block B42 and the corresponding tightening blocks 44;

[0023] As Figure 3 shown, a plurality of "cross" shaped sliding grooves 46 are equidistantly formed on the upper surfaces of the arc-shaped clamping block A41 and the arc-shaped clamping block B42. By sliding the "cross" shaped lifting blocks 43 in the corresponding "cross" shaped sliding grooves 46, the sliding connection between the arc-shaped clamping block A41 and the arc-shaped clamping block B42 and the corresponding "cross" shaped lifting blocks 43 is realized;

[0024] It should be noted that, as Figure 4 shown, the adjusting device 6 includes a threaded rod 61. The arc-shaped clamping block A41 and the arc-shaped clamping block B42 are screwed with the corresponding threaded rods 61. An operating block 62 is fixedly installed at the right end of the threaded rod 61. An "I" shaped column 63 is fixedly installed at the left end of the threaded rod 61. The "I" shaped column 63 is rotatably connected with the corresponding tightening block 44;

[0025] When adjusting the clamping position of the tightening block 44, the threaded rod 61 can be driven to rotate by rotating the operating block 62, so that the inner end of the threaded rod 61 moves inward, thereby driving the tightening block 44 to move inward by using the "I" shaped column 63 to reduce the clamping distance. When the tightening block 44 moves, it will also drive the "cross" shaped lifting block 43 to move inward, so as to facilitate the lifting and clamping work of the large hydraulic cylinder 7 with a smaller diameter. Compared with the prior art, it has stronger applicability and is more convenient to use.

[0026] Since when adjusting the clamping distance, it is necessary to adjust multiple tightening blocks 44 inward by the same distance to ensure the stability of the large hydraulic cylinder parts 7 when being lifted and clamped. As Figure 3 shown, a distance mark 431 is engraved in the depression on the front surface of the "cross" shaped lifting block 43. During adjustment, the outer surface edge of the arc-shaped clamping block A41 or the arc-shaped clamping block B42 is used to judge whether the values of the distance marks 431 are the same, so as to judge whether the distances that the tightening blocks 44 move inward are the same.

[0027] Specifically, as Figure 3As shown, two limiting blocks 411 are fixedly installed on the outer surfaces of both ends of the arc-shaped clamping block A41, and insertion blocks 421 are fixedly installed on the outer surfaces of both ends of the arc-shaped clamping block B42. The insertion blocks 421 are inserted and installed between two corresponding upper and lower limiting blocks 411, and a positioning pin 45 is inserted and installed between the insertion block 421 and the two corresponding limiting blocks 411. The positioning pin 45 is used to fix the insertion block 421 between the two corresponding upper and lower limiting blocks 411. When the insertion blocks 421 on both sides are respectively fixed between the two corresponding upper and lower limiting blocks 411, the arc-shaped clamping block A41 and the arc-shaped clamping block B42 are fixed together.

[0028] In addition, to avoid scratching the outer surface of the large hydraulic cylinder part 7 during the clamping and lifting process, as Figure 3 shown, rubber pads A432 are fixedly installed on the upper surfaces of the "cross" - shaped lifting blocks 43, and rubber pads B441 are fixedly installed on the inner surfaces of the pressing blocks 44. The rubber pads A432 and the rubber pads B441 can be used to contact the outer surface of the large hydraulic cylinder part 7, so as to avoid scratching the outer surface of the large hydraulic cylinder part 7 during the lifting and clamping process.

[0029] Specifically, as Figure 1 shown, two fixing rings 5 are symmetrically and fixedly installed on the outer surfaces of the arc-shaped clamping block A41 and the arc-shaped clamping block B42. A hoisting plate 21 is fixedly installed inside the support frame 2. The hoisting device 3 includes a hydraulic telescopic column 31. The hydraulic telescopic column 31 passes through and is hoisted on the lower surface of the hoisting plate 21, and a hanging plate 32 is fixedly installed on the lower surface of the hydraulic telescopic column 31. Four suspension ropes 33 are symmetrically and fixedly installed on the lower surface of the hanging plate 32. The bottom ends of the suspension ropes 33 are fixedly connected with hooks 34. The hooks 34 are hung in the corresponding fixing rings 5. When the hydraulic telescopic column 31 contracts, the arc-shaped clamping block A41 and the arc-shaped clamping block B42 fixed together can be driven to move upward by the suspension ropes 33 and the hooks 34.

[0030] When in use, first, the arc-shaped clamping block A41 and the arc-shaped clamping block B42 are buckled together from the outside of the large hydraulic cylinder part 7, and the arc-shaped clamping block A41 and the arc-shaped clamping block B42 are fixed together by using the positioning pin 45. After that, rotate the threaded rod 61 to drive the pressing block 44 to move towards the large hydraulic cylinder part 7, so that the inner surfaces of the plurality of pressing blocks 44 are all attached to the outer surface of the large hydraulic cylinder part 7. After that, driving the hydraulic telescopic column 31 to contract can drive the arc-shaped clamping block A41 and the arc-shaped clamping block B42 fixed together to move upward by using the lifting rope 33 and the hook 34, and make the lower surface of the top edge of the large hydraulic cylinder part 7 fit above the "cross"-shaped lifting block 43. Finally, press the pressing block 44 against the outer surface of the large hydraulic cylinder part 7 to clamp and fix it. Again, further drive the hydraulic telescopic column 31 to contract to lift the large hydraulic cylinder part 7 away from the ground, and then push the U-shaped base 1 to carry out short-distance handling of the large hydraulic cylinder part 7.
