DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] See also Figures 1-4 A drum assembly for lifting machinery includes a drum assembly and a support assembly. The drum assembly includes two side plates 1, a hexagonal connecting rod 2 is fixedly connected between the two side plates 1, and multiple hydraulic cylinders 3 are fixedly installed on the outer wall of the hexagonal connecting rod 2. The output end of the hydraulic cylinder 3 is fixedly connected to an arc plate 4.

[0026] When the hydraulic cylinder 3 is working, it can drive the arc plate 4 to move, and further change the size of the reel assembly, thereby increasing the scope of use, thus improving applicability and facilitating practical application.

[0027] The support assembly includes a base plate 5 and a moving block 6. A plurality of fixing holes 7 are opened at the top of the base plate 5. Two fixing plates 8 are fixedly connected to the top of the base plate 5. A bidirectional screw 9 is rotatably arranged between the two fixing plates 8. Two sliders 10 are screwed on the outside of the bidirectional screw 9. A support rod 11 is hinged between the slider 10 and the moving block 6. The side plate 1 is rotatably connected to the moving block 6.

[0028] The setting of the fixing hole 7 makes it convenient to fix the base plate 5 at the desired location. When the bidirectional screw 9 rotates, the slider 10 moves, and the moving block 6 moves under the connection action of the support rod 11, which can adjust the height of the reel assembly and further improve the applicability of the device.

[0029] See also Figure 2 and Figure 3 A plurality of hydraulic cylinders 12 are fixedly mounted on the outer wall of the hexagonal connecting rod 2, and a plug plate 13 is fixedly connected to the output end of the hydraulic cylinder 12.

[0030] When the arc-shaped plate 4 moves, a gap will appear between the two arc-shaped plates 4. At this time, the hydraulic cylinder 2 12 is started to move the plug plate 13, and the gap can be filled by the plug plate 13, so that the reel assembly can function normally and stably.

[0031] See also Figure 3A plurality of limiting sleeves 14 and a plurality of limiting sleeves 2 15 are fixedly connected to the outer wall of the hexagonal connecting rod 2. A limiting rod 16 and a limiting rod 2 17 are respectively slidably provided inside the limiting sleeve 14 and the limiting sleeve 2 15. The limiting rod 16 and the limiting rod 2 17 are respectively fixedly connected to the arc plate 4 and the plug plate 13.

[0032] The setting of the limiting sleeve 14 and the limiting rod 16 can provide an additional limiting effect for the arc plate 4, making the arc plate 4 more stable. At the same time, the limiting sleeve 2 15 and the limiting rod 2 17 can limit the plug plate 13, making the plug plate more stable, thereby ensuring that the reel assembly has sufficient stability.

[0033] See also Figure 2 A plurality of connecting rods 18 are fixedly connected between the two side panels 1 .

[0034] The connecting rod 18 can improve the stability of the two side plates 1, and further improve the stability of the entire reel assembly.

[0035] See also Figure 4 A crank 19 is fixedly connected to the side wall of the bidirectional screw 9.

[0036] The setting of the crank 19 can facilitate the rotation of the bidirectional screw 9, and thus facilitate the adjustment of the height of the reel assembly.

[0037] In summary, the working principle and working process of the drum assembly for lifting machinery are as follows: when in use, first fix the base plate 5 at the desired location, then rotate the crank 19 to move the moving block 6 until the drum assembly moves to a suitable height, then stop turning the crank 19, and then according to actual conditions, if you need to change the size of the drum assembly, just start the hydraulic cylinder 1 3 to move the arc plate 4 to a suitable position, then start the hydraulic cylinder 2 12 to move the plug plate 13 to the inside of the gap between the two arc plates 4, and then it can be put into normal use. The drum assembly for lifting machinery is convenient for adjusting the height and size of the drum assembly, has a wide range of use, high applicability, and is conducive to practical application.

[0038] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
