[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] An example of the implementation of the detachable device for raising the mechanical lifting height in this invention is... Figure 1-4 As shown.

[0024] Example 1

[0025] The detachable lifting device for raising the mechanical lifting height in this embodiment includes a base and a support plate 6 for lifting heavy steel components. The base and support plate 6 are connected by four adjustable support rods 4. The base includes two square tubes 1 arranged in parallel, with the spacing between them customized according to the size of the forklift forks. The two square tubes 1 are connected by two connecting rods 2, which are welded to each other. The distance from the connection point of the connecting rod to the nearest end of the square tube 1 is one-fifth of the length of the square tube 1. The square tube 1 is a square steel tube, and the connecting rod 2 is a round steel tube. Both square tubes 1 are hollow inside and extend in the left-right direction. Both ends of the lower wall of each square tube 1 have through holes extending in the up-down direction (not shown in the figure). Nuts 12 are welded to the inner wall of each square tube 1. Fixing components for securing mechanical equipment are connected to the through holes; these components are bolts 11, which are threadedly connected to the nuts 12. The distance between the nut 12 and the nearest end of the square tube 1 is 15-20 cm. Adjustable support rods 4 are connected to both ends of each square tube 1. The adjustable support rods 4 are welded to the square tube 1, and the distance from the connection point of the adjustable support rod 4 to the end of the square tube 1 is one-fifth of the length of the square tube 1. The adjustable support rod 4 includes an upper rod 41 and a lower rod 44. The lower rod 44 includes a lower support rod 45 and a lower support rod 46. Both support rod 45 and support rod 46 are round steel pipes; the diameter of support rod 46 is smaller than the diameter of support rod 45. The upper rod 41 is a round steel tube with a hollow interior. It is fitted onto the second support rod 46, with its inner wall tightly against the outer wall of the second support rod 46. An adjusting ring 5 connects the upper rod 41 and the lower rod 44. The adjusting ring 5 extends vertically and is integrally formed. It is hollow inside and has an internal thread at its lower part. The second support rod 46 has an external thread at its lower part, and the adjusting ring 5 is threadedly connected to the second support rod 46. A connecting rod 42 is provided at the lower end of the upper rod 41. The upper rod 41 and the connecting rod 42 are integrally formed, and the diameter of the connecting rod 42 is smaller than the diameter of the upper rod 41. The upper inner wall of the adjusting ring 5 is tightly attached to the outer wall of the connecting rod 42, and the inner wall of the connecting rod 42 is tightly attached to the outer wall of the support rod 46. An L-shaped retaining plate 51 is provided on the inner wall of the adjusting ring 5, extending circumferentially along the inner wall of the adjusting ring 5. A groove 43 that mates with the retaining plate 51 is provided on the outer wall of the connecting rod 42 so that the upper rod 41 can slide and connect with the adjusting ring 5. When the adjusting ring 5 is turned, it extends along the vertical direction of the lower rod 44, thereby driving the upper rod 41 to move vertically, thus adjusting the height of the adjustable support rod 4. Since the retaining plate 51 of the adjusting ring 5 is engaged in the groove 43 of the connecting rod 42 and is slidably connected with the connecting rod 42, the upper rod will not move with the turning of the adjusting ring 5.

[0026] The upper end of the adjustable support rod 4 is connected via connecting rod 3, which is welded to the adjustable support rod 4. Connecting rod 3 is a square steel tube and is parallel to connecting rod 2. The upper end of the adjustable support rod 4 is welded to support plate 6. There are two support plates 6, extending in the left-right direction. Support plates 6 are steel plates. The number of support plates 6 can be set to one as needed.

[0027] To install this detachable device for raising the mechanical lifting height, insert the forklift forks into the square tube, then raise the forks, and finally tighten the bolts so that the upper surface of the bolts abuts against the lower surface of the forks.
