Description

Technical Field

[0001] The utility model relates to the technical field of cable production equipment, in particular to a combined reinforced pressing wheel assembly. Background Art

[0002] Because the designed outer diameter of superconducting cables used in nuclear fusion devices is much smaller than the natural outer diameter of the cable strands, and the superconducting filaments are relatively hard and have almost no elongation, measures must be taken to reduce the outer diameter during the cable stranding. To prevent the niobium coating on the surface of the superconducting strands from being scraped off during the reduction process, or the superconducting strands on the surface of the superconducting cable from being easily deformed and broken, our company has now changed the original superconducting cable clamping wheel from a steel wheel design to a combined reinforced non-metallic clamping wheel. At the same time, the designed combined reinforced non-metallic clamping wheel is not only extremely prone to damage to the non-metallic clamping body, wire gland, and steel structure reinforcement flange during disassembly; the disassembly process is also time-consuming and labor-intensive, undoubtedly increasing the labor intensity of the operators. Therefore, we have designed matching disassembly components. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] Example 1

[0021] like Figure 1-3 The present embodiment provides a combined reinforced pressing wheel assembly, including a steel structure reinforcement body 5, a deep groove ball bearing 1 is installed inside the steel structure reinforcement body 5, a flange is provided on the rear end of the steel structure reinforcement body 5, an external thread is provided on the front end, a non-metallic pressing body 4 is sleeved on the steel structure reinforcement body 5, and a threaded pressure cover 2 is threadedly provided on the front end head of the steel structure reinforcement body 5 on the front side of the non-metallic pressing body 4, and two through holes are symmetrically provided on the threaded pressure cover 2 and the flange of the steel structure reinforcement body 5 along the diameter direction.

[0022] The assembly also includes a disassembly plate I3 and a plurality of hexagon socket head screws 7. The disassembly plate I3 can be mounted on the threaded gland 2 via the hexagon socket head screws 7. The disassembly plate I3 is provided with two threaded holes corresponding to the through holes on the threaded gland 2, one of which is located in the middle of the disassembly plate I3 and the other at one end of the disassembly plate I3. The threaded sections 72 of the hexagon socket head screws 7 are screwed into the threaded holes of the disassembly plate I3, and the cylindrical heads 71 ​​of the hexagon socket head screws 7 are correspondingly inserted into the through holes on the threaded gland 2. The cylindrical heads 71 ​​and the through holes on the threaded gland 2 are in a clearance fit. This allows for flexible rotation of the disassembly plate I and the threaded gland and prevents slipping.

[0023] It also includes a disassembly plate II6, which can be set on the flange of the steel structure reinforcement body 5 through a hexagon socket cylindrical head screw 7. The disassembly plate II6 is provided with two threaded holes corresponding to the through holes on the flange of the steel structure reinforcement body 5, one of which is set in the middle of the disassembly plate II6, and the other threaded hole is set at one end of the disassembly plate II6. The threaded section 72 of the hexagon socket cylindrical head screw 7 is screwed into the threaded hole of the disassembly plate II6, and the cylindrical head 71 of the hexagon socket cylindrical head screw 7 is correspondingly inserted into the through hole on the flange of the steel structure reinforcement body 5, and the cylindrical head 71 is gap-matched with the through hole on the flange of the steel structure reinforcement body 5.

[0024] The disassembly plate I3 and the disassembly plate II6 are processed from hot-rolled flat steel plates into strip plates of the same shape, and the processed width must be sufficient to be gripped by hand; the length of the disassembly plate I3 is greater than the diameter of the wire pressure cover 2, so that the disassembly plate I3 extends out of the wire pressure cover 2 for convenient hand-gripping operation; the length of the disassembly plate II6 is greater than the diameter of the flange of the steel structure reinforcement body 5, so that the disassembly plate II6 extends out of the flange of the steel structure reinforcement body 5 for convenient hand-gripping operation.

[0025] The length of the threaded section 72 of the hexagon socket cylindrical head screw 7 is 2-3 mm larger than the thickness of the disassembly plate Ⅰ3 and the disassembly plate Ⅱ6. The diameter of the cylindrical head 71 of the hexagon socket cylindrical head screw 7 is slightly smaller than the diameter of the outer thread of its threaded section 72. The length of the cylindrical head 71 of the hexagon socket cylindrical head screw 7 is not greater than the thickness of the threaded cover 2 and the thickness of the flange of the steel structure reinforcement body 5.

[0026] The diameter and thickness of the flange of the steel structure reinforcement body 5 are respectively the same as the diameter and thickness of the wire gland 2, and the thickness of the disassembly plate I3 is the same as that of the disassembly plate II6.

[0027] When it is necessary to load and unload the threaded pressure cover 2 from the combined reinforced clamping wheel, the cylindrical heads 71 ​​of the two hexagon socket head screws 7 threaded on the disassembly plate I3 need to be stuck in two through holes of exactly the same size that are symmetrically processed in the circumferential direction of the threaded pressure cover 2; the cylindrical heads 71 ​​of the two hexagon socket head screws 7 threaded on the disassembly plate II6 need to be stuck in two through holes of exactly the same size that are symmetrically processed in the circumferential direction of the flange of the steel structure reinforcement body 5; then, use your left and right hands to hold the disassembly plate I3 and the disassembly plate II6 tightly, one end of the threaded pressure cover 2 or the flange of the steel structure reinforcement body 5, and the threaded pressure cover 2 can be removed or tightened from the combined reinforced clamping wheel.

[0028] In this embodiment, the disassembly plate I3 and the disassembly plate II6 are processed into the same shape and thickness. At the same time, the thickness of the flange of the wire cover 2 and the steel structure reinforcement body 5 and the size of the through hole in the circumferential direction are also processed into the same size, so that the disassembly plate I3 and the disassembly plate II6 can be used interchangeably, making loading and unloading more convenient.

[0029] Alternatively, one end of the disassembly plate I3 and the disassembly plate II6 may be clamped on a vise before disassembly or installation, which results in a better disassembly or installation effect.

[0030] Example 2

[0031] This embodiment differs from Example 1 in that the two hexagon socket head cap screws b are machined so that the cylindrical heads at the ends of the hexagon socket head cap screws b are longer than the thickness of the flange of the steel structure reinforcement body 5. During use, the cylindrical heads of the two extended hexagon socket head cap screws b are inserted into the two through-holes on the flange of the steel structure reinforcement body 5, thereby easily removing the non-metallic pressing body 4.
