Description

Technical Field

[0001] This patent relates to the field of crane drum technology, specifically a drum assembly with a positioning structure. Background Art

[0002] The drum group is an important component of lifting machinery and equipment. During the use of the crane, the drum group is installed on the crane trolley frame, and the wire rope is wound around the drum of the drum group to achieve the lifting of the crane hook. In order to increase the positioning effect of the wire rope, two limit rollers are set on the upper side of the drum, and the wire rope passes through the two limit rollers to connect with the drum. With long-term use, the rollers will be severely worn and need to be replaced. However, the existing rollers and the housing need to be connected by multiple sets of bolts, which makes the disassembly and assembly of the rollers inconvenient, and the bolts do not have a positioning structure, which makes it easy for the rollers to get stuck. For this reason, we propose a drum group with a positioning structure. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0017] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 This patent provides a technical solution: a reel assembly with a positioning structure, comprising a reel body 1, a rope groove 2 is provided on the side wall of the reel body 1, a seat plate 3 is provided on the left and right sides of the reel body 1, the reel body 1 and the seat plate 3 are connected by a rotating shaft, a connecting rod 4 is fixedly installed on the top of the seat plate 3, a U-shaped frame 5 is fixedly installed on the top of the connecting rod 4, rollers 6 are provided on the left and right sides of the U-shaped frame 5, and the inner ends of the rollers 6 are relatively close;

[0018] A first slot 7 and a second slot 8 are respectively provided at the left and right ends of the front and rear side walls of the roller 6. A fixed shaft 9 is fixedly installed on the left and right sides of the inner rear side wall of the U-shaped frame 5. The two rollers 6 are respectively sleeved on the two fixed shafts 9. A threaded groove 10 is provided at the rear end of the fixed shaft 9. An annular groove 11 is provided on the left and right sides of the inner rear side wall of the U-shaped frame 5. A first bearing 12 is provided in the annular groove 11. The outer side wall of the outer ring of the first bearing 12 is fixedly installed on the inner outer side wall of the annular groove 11. A first plug rod 13 is fixedly installed on the left and right ends of the inner ring of the first bearing 12. The first plug rod 13 is inserted in the first slot 7. A second bearing 14 is attached to the rear end of the fixed shaft 9. A bolt 15 is provided in the inner ring of the second bearing 14. The end of the bolt 15 is screwed in the threaded groove 10. The left and right ends of the outer ring of the second bearing 14 are fixedly installed with a second plug rod 16 through a connecting block. The second plug rod 16 is inserted in the second slot 8.

[0019] like Figure 3 As shown, the inner ring of the first bearing 12 and the outer ring of the second bearing 14 rotate along with the roller 6 .

[0020] Specifically, the side wall of the first inserting rod 13 and the inner side wall of the first slot 7 are relatively fitted and slid, and the side wall of the second inserting rod 16 and the inner side wall of the second slot 8 are relatively fitted and slid.

[0021] By the side wall of the first plug rod 13 slidingly fitting with the inner wall of the first slot 7 and the side wall of the second plug rod 16 slidingly fittingly fitting with the inner wall of the second slot 8, the tightness of the connection between the first plug rod 13 and the second plug rod 16 and the roller 6 can be increased.

[0022] Specifically, the bolt 15 includes a T-rod 17 and a pressure ring 19. The end of the T-rod 17 is integrally formed with a screw 18, which is threaded into the thread groove 10. The inner wall of the pressure ring 19 is in relative contact with the side wall of the T-rod 17. The end of the T-rod 17 is tightly fitted on one side of the pressure ring 19, and the other side of the pressure ring 19 is tightly fitted on the inner ring of the second bearing 14. Positioning grooves 21 are provided on both ends of the inner ring of the second bearing 14. Positioning rods 20 are integrally formed on both ends of the other side of the pressure ring 19, and the positioning rods 20 are inserted into the positioning grooves 21.

[0023] like Figure 4 As shown, the T-bar 17 is screwed into the threaded groove 10 through the screw 18. At this time, the T-bar 17 will not move in various positions, the inner wall of the pressure ring 19 is in relative contact with the side wall of the T-bar 17, and the pressure ring 19 will not move. Then, the positioning rod 20 is inserted into the positioning groove 21, which can increase the positioning effect of the inner ring of the second bearing 14 and avoid movement.

[0024] Specifically, the side walls of the T-bar 17 and the screw rod 18 do not contact the inner side wall of the inner ring of the second bearing 14 .

[0025] By preventing the side walls of the T-bar 17 and the screw rod 18 from contacting the inner side wall of the inner ring of the second bearing 14, it is avoided that when the screw rod 18 and the threaded groove 10 are installed, the side walls of the T-bar 17 and the screw rod 18 contact the inner side wall of the inner ring of the second bearing 14 and cause movement obstruction.

[0026] Specifically, an annular groove 22 is provided at the outer edge of the rear end of the fixed shaft 9 , and the annular groove 22 corresponds to the outer ring position of the second bearing 14 .

[0027] like Figure 4 As shown, by providing the annular groove 22, the outer edge of the rear end of the fixed shaft 9 can be prevented from contacting the outer ring of the second bearing 14, thereby reducing the friction effect when the outer ring of the second bearing 14 rotates.

[0028] Working principle: The wire rope used for lifting can pass through two rollers 6 and be fixedly connected to the starting end of the rope groove 2. The drum 1 is rotated and controlled by the traction machine shaft of the crane. The wire rope is wound in the continuous rope groove 2. At the same time, the two rollers 6 will be driven to rotate when the wire rope is wound. When the roller 6 is worn for a long time, the bolt 15 and the threaded groove 10 can be removed, the second bearing 14 and the second plug rod 16 can be removed from the second slot 8, and then the roller 6 can be removed from the rear end of the fixed shaft 9 to complete the disassembly.
