Description
Technical Field
[0001] The utility model relates to the technical field of crane folding drum rope winding, in particular to a folding drum rope winding deflection angle adjustment system. Background Art
[0002] A fold line drum refers to a cylindrical drum structure with a series of fold lines. During operation, this type of drum can effectively prevent the loosening and dislocation of the wound material. Cranes often use fold line drums to wind or unwind wire ropes.
[0003] In the prior art, when the folding wire drum is winding the wire rope, the wire rope passes through the redirecting pulley fixed on the roof of the machine room, and then is wound around the folding wire drum. The reasonable deflection angle range between the wire rope passing through the redirecting pulley and the folding wire drum is generally 0.5° to 1.5°, and the deflection angle range can ensure that the wire rope is evenly wound around the folding wire drum.
[0004] However, the deflection angle range is small, and there is often deviation in the installation of the folding wire reel. After long-term use, the folding wire reel and the wire rope will be deformed and the wire rope will have tolerances, which will cause the deflection angle of the folding wire reel and the wire rope to become larger. When the deflection angle exceeds the reasonable deflection angle range, the wire rope will be tangled when it is wrapped around the folding wire reel, thereby affecting the effect of the folding wire reel winding.

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] like Figure 1-Figure 9 As shown, a folding drum rope angle adjustment system comprises: a machine room floor 1, a roller bracket 4 and an adjustment component.
[0032] A folding wire drum 10 is fixedly connected to the top of the machine room floor 1, and support columns 2 are fixedly connected to the top of the machine room floor 1. A crossbeam 3 is fixedly connected to the top of the support column 2. The folding wire drum 10 is generally installed on the machine room floor 1 to wind or unwind the wire rope, and the redirection pulley is generally installed on the top of the crossbeam 3 and used in conjunction with the folding wire drum 10;
[0033] There are two groups of roller brackets 4, and both ends of the roller brackets 4 are fixedly connected to the support column 2 respectively. Guide grooves 20 are respectively provided at both ends of the roller brackets 4 along the length direction. A positioning plate 11 is provided between the two groups of roller brackets 4. Both ends of the positioning plate 11 are respectively fixedly connected to the roller brackets 4. The roller brackets 4 are used to provide support and fixation for the adjustment components. The guide grooves 20 provided on the top of the roller brackets 4 facilitate the stability of the adjustment components sliding on the top of the roller brackets 4. When the adjustment components slide on the top of the roller brackets 4, the guide grooves 20 limit the trajectory of the movement of the adjustment components.
[0034] The adjusting component is arranged on the top of the roller bracket 4 and is slidably connected to the roller bracket 4. The adjusting component is cooperatively connected to the folding wire drum 10. The side end of the adjusting component is fixedly connected with a connecting plate 7. When the adjusting component moves to a suitable position on the roller bracket 4, after the wire rope passes through the redirecting pulley, the wire rope sweeps on the folding wire drum 10. The angles on both sides of the wire rope and the folding wire drum 10 exceed the reasonable deflection range. The adjusting component starts to support the wire rope, and the angles of the wire rope and the folding wire drum 10 are restored to a reasonable deflection range, thereby avoiding the phenomenon of tangled ropes when the folding wire drum 10 is winding the wire rope, and ensuring the normal operation of the folding wire drum 10.
[0035] In some specific embodiments, the cross-section of the roller bracket 4 is I-shaped, and a plurality of adjustment holes 12 are equidistantly provided at both ends of the top of the roller bracket 4 along the length direction, and a positioning bolt 15 is threadedly connected to the inner thread of the adjustment hole 12. The adjustment component is provided with a plurality of positioning holes 14 in the axial direction of the adjustment hole 12, and the positioning holes 14 are interconnected with the adjustment holes 12 and the positioning holes 14 are threadedly connected to the positioning bolts 15. In order to ensure that the adjustment component can be fixed after being moved on the roller bracket 4, the adjustment hole 12 provided on the top of the roller bracket 4 can be compatible with the adjustment component, and the positioning bolts 15 are installed in the adjustment hole 12 and the positioning hole 14, so that the adjustment component is installed on the roller bracket 4.
[0036] In some specific embodiments, the adjustment component includes: a roller support plate 5, a roller 6, an adjustment plate 13 and a guide plate 21. The roller support plate 5 and the adjustment plate 13 are each provided with two groups. The roller support plate 5 is fixedly connected to the adjustment plate 13. The adjustment plate 13 is slidably connected to the top of the roller bracket 4. A number of positioning holes 14 are equidistantly provided at both ends of the top of the adjustment plate 13 along the length direction of the roller bracket 4. The two ends of the roller 6 are rotatably connected to the inner wall of the roller support plate 5. The roller 6 is cooperatively connected to the folding reel 10. The guide plate 21 is slidably connected to the guide groove 20. The two ends of the connecting plate 7 are respectively fixedly connected to the adjustment plate 13. The guide plate 21 is provided with two groups and is located at the two ends of the bottom of the adjustment plate 13. The guide plate 21 is connected to the adjustment groove 20. The section plate 13 is fixedly connected. In order for technicians in this field to better understand the working principle of the adjustment assembly of the utility model, when the adjustment assembly moves, the adjustment plate 13 slides on the top of the roller bracket 4. In order to ensure the stability of the sliding of the adjustment plate 13, the adjustment plate 13 drives the guide plate 21 to slide along the guide groove 20. When the adjustment plate 13 drives the roller 6 to move through the roller support plate 5, the roller 6 resists the wire rope, and the roller 6 repairs the deflection of the wire rope by moving. When the deflection angle of the wire rope returns to a suitable deflection angle range, stop moving the adjustment plate 13. When the roller 6 and the wire rope resist, the movement of the wire rope drives the roller 6 to rotate.
[0037] In some specific implementation schemes, the connecting plate 7 is provided with a limiting groove 16 at one end near the cross beam 3, a driving machine 9 is fixedly connected to the top of the cross beam 3, a push rod 8 is provided between the driving machine 9 and the connecting plate 7, the push rod 8 is fixedly connected to the driving machine 9 and is connected with the connecting plate 7, the push rod 8 is fixedly connected to the limiting plate 17 at the side end near the connecting plate 7, the limiting plate 17 is limitedly connected to the limiting groove 16, and fixing holes 19 penetrating the limiting plate 17 are respectively provided at both ends of the inner part of the limiting groove 16, and the fixing holes 19 are connected with fixing bolts 18 in the inner threads, and the fixing bolts 18 are abutted and connected with the limiting plate 17. Since the adjustment component is installed on the support column 2 , the adjusting component is at a height. In order to facilitate the movement of the adjusting component, the staff uses a handheld remote control to control the operation of the driving machine 9. The driving machine 9 drives the push rod 8 to move. The push rod 8 supports the connecting plate 7 through the limit plate 17 to move. The connecting plate 7 supports the adjusting component to move, thereby achieving the effect of facilitating the repair of the wire rope by the adjusting component. It should be noted that the limit plate 17 is installed in the limit groove 16 by the fixing bolt 18. When the adjusting component is installed on the roller bracket 4, the push rod 8, the driving machine 9 and the limit plate 17 can be removed by releasing the threaded connection between the fixing bolt 18 and the fixing hole 19.
[0038] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
