[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a combined crane counterweight block.

[0027] This utility model provides, for example Figures 1-4 The combined crane counterweight block shown includes a top plate 1. The top plate 1 has multiple symmetrically arranged sliding holes 2 inside. A vertical rod 3 slides through the sliding holes 2. A limiting side plate 4 is fixedly installed at the bottom of the vertical rod 3. The longitudinal section of the limiting side plate 4 is L-shaped. Multiple counterweight blocks 5 are stacked between the multiple limiting side plates 4. Multiple unidirectional limiting mechanisms are spaced apart inside the limiting side plates 4. Each unidirectional limiting mechanism includes a support rod 7, which slides on the side of the limiting side plate 4 and has a stop block 8 fixedly installed at its end. The stop block 8 is a wedge-shaped block and is installed inside the limiting side plate 4. A spring 9 is sleeved on the wall of the support rod 7, and both ends of the spring 9 are fixedly connected to the support rod 7 and the limiting side plate 4, respectively.

[0028] In order to facilitate the adjustment of the combination range of multiple limiting side plates 4 according to the specifications of the counterweight 5 to be set, such as Figures 1-2As shown, a cover plate 6 is fixedly provided on the top of each of the multiple vertical rods 3. A combined range adjustment mechanism for adjusting the position of the limiting side plate 4 is provided between the multiple cover plates 6 and the top plate 1. The combined range adjustment mechanism includes a support cylinder 10, which is fixedly provided on the top of the top plate 1 and has an adjusting stud 11 rotatably inserted inside. The adjusting stud 11 is rotatably engaged with the inner wall of the support cylinder 10 through its external bearing. A sliding plate 12 is threaded on the outer wall of the adjusting stud 11. Multiple first connecting plates 13 arranged symmetrically around the outer wall of the sliding plate 12 are fixedly provided on the outer wall of the sliding plate 12. A second connecting plate 14 is fixedly provided on the top of each of the multiple cover plates 6. A push plate 15 is rotatably provided between the two first connecting plates 13 and the second connecting plate 14 on the same side. Both ends of the push plate 15 are rotatably engaged with the first connecting plates 13 and the second connecting plates 14 through axle pins. A rotating block 16 is fixedly provided on the top of the adjusting stud 11.

[0029] Instructions for use: When using the counterweight of this combined crane, first adjust the combination range between the limit side plates 4 according to the actual needs using the combination range adjustment mechanism. Rotate the rotating block 16 on the top of the adjusting stud 11. Since the adjusting stud 11 rotates with the inner wall of the support cylinder 10 through the external bearing, the rotating block 16 drives the adjusting stud 11 to rotate inside the support cylinder 10. The outer wall of the adjusting stud 11 is threaded with a sliding plate 12. According to the principle of thread transmission, the sliding plate 12 will move up and down along the axis of the adjusting stud 11.

[0030] When the skateboard 12 moves, it drives the push plate 15 to move through the first connecting plate 13, so that the push plate 15 can flexibly change its angle during the movement, thereby pushing the cover plate 6. The cover plate 6 is fixedly connected to the vertical rod 3. The bottom of the vertical rod 3 is provided with a limiting side plate 4. Therefore, the movement of the cover plate 6 will drive the vertical rod 3 and the limiting side plate 4 to move laterally, thereby adjusting the distance between multiple limiting side plates 4 to adapt to the combination requirements of different specifications of counterweights.

[0031] After adjusting the position of the limiting side plate 4, start assembling the counterweight 5. Push the first counterweight 5 from the bottom of the multiple limiting side plates 4 to the top. During the pushing process, when the counterweight 5 contacts the stop block 8, since the stop block 8 is a wedge-shaped block, the counterweight 5 will squeeze the stop block 8, causing the support rod 7 to slide into the limiting side plate 4. The spring 9 is compressed. When the counterweight 5 passes the stop block 8, under the elastic force of the spring 9, the support rod 7 drives the stop block 8 to return to its original position. The stop block 8 provides one-way support for the counterweight 5, preventing the counterweight 5 from sliding down. In this way, by pushing the counterweight 5 in sequence, the stacking and combination of multiple counterweight 5 can be quickly completed under the one-way support of the stop block 8.

[0032] When it is necessary to remove the counterweight, the support rods 7 in the multiple one-way limit mechanisms on the same horizontal line can be pulled at the same time, so that the support rods 7 can drive the stop block 8 away from the counterweight 5.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
