Nylon cable drum

Abstract

The application discloses a nylon cable roller, which comprises a fixed support, a cylindrical roller with a blocking ring fixed thereon, the cylindrical roller being rollably installed on the top of the fixed support, and an axial support limiting assembly for limiting the axial displacement of the blocking ring. The blocking ring can only rotate in the arc grooves of the vertical plates and cannot be axially displaced along the cylindrical roller, so that the cylindrical roller is axially displaced and limited in the arc grooves of the vertical plates through the blocking ring, and when the nylon cable is rolled and wound, the trajectory of the nylon cable wound on the surface of the cylindrical roller is controlled, the close distribution state between the nylon cable winding rings is improved, and the problem that the existing roller cannot be axially displaced and limited is solved.

Description

Technical Field

[0001] This utility model relates to a nylon cable roller, belonging to the technical field of construction rollers for sea breeze mooring cables. Background Technology

[0002] Floating offshore wind turbine mooring systems require anchor chains, and anchor chains composed of steel chains and nylon cables are lighter than steel anchor chains. Nylon cables are longer and need to be coiled and wound around the drums of the drum unit during transport.

[0003] There is an existing roller device for winding and coiling cables, as seen in Chinese Patent Publication No. CN215625960U. Although the roller can be rotatably mounted on a rotating bracket to wind and store nylon cables, it cannot achieve axial displacement limitation. When the roller rolls, axial displacement should be minimized as much as possible so that the nylon cable coils are more tightly distributed on the roller. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a nylon cable roller.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a nylon cable roller, comprising: Fixed bracket; A cylindrical roller with a retaining ring fixed on it, which can be rolled on top of a fixed bracket; It also includes an axial support and limiting assembly that restricts the axial displacement of the retaining ring.

[0007] The fixed brackets are arranged in two spaced intervals. A bearing seat is fixedly installed on the top of the fixed brackets, and a bearing is installed in the bearing seat. Rollers are fixed at both ends of the cylindrical roller. The rollers at both ends of the cylindrical roller are connected to the bearings at the top of the two fixed brackets by keys. The two ends of the cylindrical roller can roll and rotate with the bearings at the top of the two fixed brackets as support.

[0008] Both ends of the cylindrical roller are fixed with retaining rings, and the diameter of the retaining rings is much larger than that of the cylindrical roller.

[0009] The axial support limiting assembly includes a support limiting seat that is fixed in use and a vertical plate fixedly connected to the support limiting seat.

[0010] The vertical plate is provided with an arc groove that mates with a retaining ring at one end of the cylindrical roller. The retaining ring can rotate relative to each other within the arc grooves of the multiple vertical plates. The arc grooves of the vertical plates restrict the axial displacement of the retaining ring, thereby limiting the axial displacement of the cylindrical roller.

[0011] It also includes an arc-shaped limiting block that brakes the retaining ring at the other end of the cylindrical roller. The arc-shaped limiting block can approach the retaining ring radially from the cylindrical roller to brake it. The retaining ring is connected to a second pad through an elastic rubber body. The second pad has a support member, and the support member has a threaded hole that engages with a threaded rod to contact and abut against the arc-shaped limiting block.

[0012] A drive pulley is fixed to the end of the cylindrical roller with the arc-shaped limiting block.

[0013] The beneficial effects of this utility model are as follows: the retaining ring can only rotate relative to each other within the arc grooves of multiple vertical plates and cannot move axially along the cylindrical roller. This restricts the axial displacement of the cylindrical roller within the arc grooves of the vertical plates by the retaining ring. When the cylindrical roller rolls to wind and collect the nylon cable, it controls the trajectory of the nylon cable winding and collecting onto the surface of the cylindrical roller, improves the tight distribution between the nylon cable winding rings, and solves the problem of the roller's inability to limit axial displacement in the prior art.

Detailed Implementation

[0015] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0016] like Figure 1 As shown.

[0017] This application provides a nylon cable roller, comprising: Fixed bracket 1, which consists of two spaced-apart brackets. A bearing seat 2 is fixedly installed on the top of the fixed bracket 1, and a bearing is installed inside the bearing seat 2.

[0018] It also includes a cylindrical roller 3, with rollers fixed at both ends of the cylindrical roller 3. The rollers at both ends of the cylindrical roller 3 are connected to the bearings at the top of the two fixed supports 1 by keys. The cylindrical roller 3 can roll and rotate with the bearings at the top of the two fixed supports 1 as support.

[0019] Both ends of the cylindrical roller 3 are fixed with retaining rings 4 by retaining ring supports 41. The diameter of the retaining rings 4 is much larger than that of the cylindrical roller 3. When the nylon cable is rolled and wound onto the cylindrical roller 3, it stops after being aligned with the radial dimension of the retaining rings 4.

[0020] It also includes an axial support limiting assembly for limiting the axial displacement of the retaining ring 4 at one end of the cylindrical roller 3. The axial support limiting assembly includes a support limiting seat 51 that is fixed in use and a vertical plate 52 fixedly connected to the support limiting seat 51. The vertical plate 52 is provided with an arc groove that cooperates with the retaining ring 4 at one end of the cylindrical roller 3. The arc groove of the vertical plate 52 limits the axial displacement of the retaining ring 4, thereby limiting the axial displacement of the cylindrical roller 3.

[0021] The retaining ring 4, which is fixed to the cylindrical roller 3, cooperates in the arc groove of the vertical plate 52. The retaining ring 4 can only rotate relative to each other in the arc groove of the vertical plate 52 and cannot move axially along the cylindrical roller 3. This restricts the axial displacement of the cylindrical roller 3 in the arc groove of the vertical plate 52 by the retaining ring 4. When the cylindrical roller 3 rolls to wind and collect the nylon cable, it controls the trajectory of the nylon cable winding and collecting on the surface of the cylindrical roller 3, improves the tight distribution between the nylon cable winding rings, and solves the problem that the roller cannot limit axial displacement in the prior art.

[0022] It also includes an arc-shaped limiting block 43 that brakes the retaining ring 4 at the other end of the cylindrical roller 3. The arc-shaped limiting block 43 can approach the retaining ring 4 radially from the cylindrical roller 3 to brake. The retaining ring 4 is connected to a second pad 44 through an elastic rubber body. The second pad 44 has a support member 42. The support member 42 is provided with a threaded hole that engages with a threaded rod to contact and abut the arc-shaped limiting block 43. The threaded rod rotates on the support member 42 and pushes the arc-shaped limiting block 43 closer to the retaining ring 4 to brake.

[0023] The cylindrical roller 3 with the arc-shaped limiting block 43 has a drive pulley 6 fixed at its end. The drive pulley 6 is connected to the pulley on the output shaft of the motor via a belt. The rotation of the motor drives the drive pulley 6 to rotate via the belt, and the drive pulley 6 drives the cylindrical roller 3 to rotate, thereby achieving the winding and storage of the nylon cable.
