[0032] Embodiment. This embodiment aims to provide a horizontal wire-reeling disc, and its main function is reflected in that the central axis has strong load-bearing capacity and can expand the bearing surface at any time according to needs, and the use effect is excellent.
[0033] Refer to Figure 1 and Figure 4, including: a lower bearing platform, an upper bearing platform and a plain bearing. The lower bearing platform is horizontally placed on the ground, and the upper bearing platform is horizontally placed above the lower bearing platform, with the upper bearing platform and the base coaxially arranged. Specifically, both the lower bearing platform and the upper bearing platform include: an outer ring platform 1 and an inner ring platform 2. The outer ring platform 1 is hollow to reduce weight and facilitate displacement. There are eight connecting arms 3 distributed along the circumferential direction welded between the outer ring platform 1 and the inner ring platform 2. The connecting arms 3 can be made of channel steel or I-beam. Five arc-shaped extending arms 4 are distributed along the circumferential direction on the outside of the outer ring platform 1, and the inner arc of the arc-shaped extending arm 4 is consistent with the outer arc of the outer ring platform 1. One end of the arc-shaped extending arm 4 is hinged to the outside of the outer ring platform 1, so that the other end of the arc-shaped extending arm 4 can swing in the horizontal direction away from or close to the outer ring platform 1. The top and bottom of the arc-shaped extending arm 4 are flush with the upper and lower table surfaces of the outer ring platform 1 respectively, so that the arc-shaped extending arm 4 can be fully stressed. Among them, a magnetic block is embedded inside the swinging end of the arc-shaped extending arm 4, which is not shown in the figure, so that the swinging end of the arc-shaped extending arm 4 is magnetically attracted to the outside of the outer ring platform 1 to achieve quick fixation. By swinging the arc-shaped extending arm 4 outward, that is, in the horizontal direction away from the outer ring platform 1, the bearing surface of this wire reel can be effectively enlarged to stably bear a large-diameter winding frame.
[0034] Refer to Figure 1 and Figure 5 , a central shaft 5 is welded and fixed in the middle of the inner ring platform 2 of the lower bearing platform. An elevation seat 6 and a plain bearing 7 are sleeved outside the central shaft 5. The plain bearing 7 is located on the top of the elevation seat 6, and the elevation seat 6 is located on the upper table surface of the inner ring platform 2 of the lower bearing platform.
[0035] Refer to Figure 1-4 , a through hole 8 that fits the central shaft 5 is provided in the middle of the inner ring platform 2 of the upper bearing platform to sleeved the inner ring platform 2 outside the central shaft 5. The upper end of the central shaft 5 protrudes outside the inner ring platform 2 of the upper bearing platform, so that the protruding part of the central shaft 5 is sleeved with the shaft cylinder of the winding frame. A plurality of rollers 9 are distributed along the circumferential direction on the lower table surface of the upper outer ring platform 1. A U-shaped plate 10 is sleeved outside the rollers 9. The U-shaped opening of the U-shaped plate 10 faces downward to rotatably install the rollers 9 in the U-shaped opening. Guide plates 11 are provided on both sides of the U-shaped plate 10. The tops of the two guide plates 11 are welded and fixed to the bottom surface of the outer ring platform 1 of the upper bearing platform. At the same time, the inner sides of the two guide plates 11 are attached to the U-shaped plate 10; a rectangular guide channel 12 is provided in the middle of the guide plate 11 along the height direction. A rectangular guide post 13 protrudes from the outside of the U-shaped plate 10 corresponding to the guide channel 12. The width of the guide post 13 matches the width of the guide channel 12 to insert the guide post 13 into the corresponding guide channel 12; circular limiting bosses 14 protrude from the top of the U-shaped plate 10 and the bottom surface of the outer ring platform 1 of the upper bearing platform to install a prestressed spring 15 between the top of the U-shaped plate 10 and the lower table surface of the corresponding outer ring platform 1 and fix its position through the limiting bosses 14.
[0036] Refer to Figure 1 、Figure 4 and Figure 5 In the natural state, after the upper platform is coaxially placed on the lower platform, a pressure relief space is reserved between the upper inner ring platform 2 and the top of the plane bearing 7 below. After the winding frame is hoisted to the top of the upper platform, the upper platform uses the pressure relief space to sink under the force to make its own inner ring platform 2 press against the top of the plane bearing 7. During this period, the upper platform will squeeze the prestressed spring 15 on the top of each roller 9. The reverse action force of the prestressed spring 15 can offset part of the axial load on the upper platform, thereby enhancing the central axial bearing capacity of the pay-off drum.
[0037] During actual use, the wire winding frame is hoisted just above the pay-off drum, and the shaft tube of the wire winding frame is made to correspond to the central axis 5, and the wire winding frame is gradually lowered to sleeve its shaft tube on the outside of the central axis 5. When the wire winding frame contacts the upper support platform, the upper support platform is pressed and sinks using the pressure relief space, and the prestressed spring 15 is also compressed. The reaction force of the prestressed spring 15 is used to increase the load-bearing capacity of the pay-off drum. If the diameter of the wire winding frame is significantly larger than the diameters of the upper and lower platforms, the load-bearing surfaces of the upper and lower platforms can be expanded by swinging the arc-shaped expansion arm 4, so as to ensure stable wire unwinding by the wire winding frame.
[0038] The pay-off reel provided in this embodiment has a stronger central axial load-bearing capacity than a traditional pay-off reel, and the load-bearing surface can be expanded at any time as needed, thereby increasing the scope of application, improving the use effect, and eliminating the safety hazard of the winding frame tipping over.
[0039] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
