[0034] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0035] like Figure 1-3 As shown, this embodiment provides a locking washer, comprising:
[0036] A gasket body 1, wherein the gasket body 1 is provided with a hollow portion 2, wherein the hollow portion 2 can accommodate a columnar body having an axis perpendicular to the gasket body;
[0037] a fixing portion 3 connected to the edge of the hollow portion 2 and extending in a direction perpendicular to the gasket body 1, the fixing portion being configured to be fitted and connected to the outer periphery of the columnar body;
[0038] The limiting portion 6 is provided on the outer periphery of the gasket body 1 and is used to fit with the outer periphery of the nut of the columnar body to limit the rotation of the nut.
[0039] Specifically, the traditional locking method is difficult to adapt to the preload maintenance requirements under complex working conditions, which causes the nut to loosen easily. The fixing part 3 of the locking gasket is firmly connected to the columnar body by welding or other means, and the limiting part 6 fits with the nut to limit its rotation, which can improve the locking effect and ensure that the rod cooling bed skirt pull rod does not loosen during long-term operation.
[0040] Optionally, the gasket body 1 is a circular metal plate;
[0041] Optionally, two second grooves are opened in the middle of the gasket body 1 to form a U-shaped portion, and the U-shaped portion can be bent 90° to one side of the gasket body 1 to form the fixing portion 3 and the hollow portion 2.
[0042] Specifically, the U-shaped portion is bent to form a fixing portion 3, leaving a hollow portion 2 in the original area. This U-shaped hollow portion 2 allows for quick replacement of the gasket without removing the screw or nut, significantly improving maintenance efficiency. Furthermore, the fixing portion 3, gasket body 1, and stopper 6 can be integrally formed from a simple circular metal plate, simplifying material selection and fabrication, resulting in low cost and ease of implementation.
[0043] Optionally, the inner surface of the fixing portion 3 is an arc-shaped surface that matches the outer periphery of the column.
[0044] Specifically, the arc-shaped inner surface of the fixing portion 3 can fit tightly with the columnar body, making the fixation more secure.
[0045] Optionally, the width of the hollow portion 2 matches the outer diameter of the columnar body.
[0046] In this embodiment, the width of the U-shaped portion is slightly larger than the outer diameter of the columnar body, which facilitates installation on the one hand and ensures the stability of the gasket body 1 on the other hand.
[0047] Optionally, a plurality of first grooves are evenly opened on the outer circle of the gasket body 1 to form a plurality of fan-shaped portions, and the fan-shaped portions can be bent 90° toward the other side of the gasket body 1 to form the limiting portion 6.
[0048] Specifically, multiple fan-shaped portions can be bent simultaneously to form multiple limiting portions 6, which simultaneously lock the nut and improve the anti-loosening effect. Alternatively, only one fan-shaped portion can be bent to form a limiting portion 6. When a limiting portion 6 is damaged, other fan-shaped portions can be bent to replace it, thereby extending the service life of the gasket.
[0049] Optionally, there are six first grooves.
[0050] Specifically, six radial grooves form six sector-shaped portions, which match the outer hexagon of the nut to improve the locking effect.
[0051] Optionally, the fixing portion 3 is provided with a fixing hole 4 .
[0052] In this embodiment, a fixing bolt 5 is provided in the fixing hole 4 , and the fixing bolt 5 is used to connect with the columnar body.
[0053] This embodiment also provides a bar cooling bed skirt plate pull rod, comprising:
[0054] Tie rod body;
[0055] A pair of locking washers in this embodiment.
[0056] Optionally, the pull rod body includes:
[0057] Pull-up rod 7;
[0058] Lower rod 8;
[0059] A double-ended connecting screw 11, one end of which is threadedly connected to the upper pull rod 7, and the other end of which is threadedly connected to the lower pull rod 8;
[0060] An upper locking nut 9, which is threadedly connected to one end of a double-headed connecting screw 11;
[0061] A lower locking nut 10, which is threadedly connected to the other end of the double-headed connecting screw 11;
[0062] A pair of locking washers are respectively arranged between the upper pull rod 7 and the upper locking nut 9 and between the lower pull rod 8 and the lower locking nut 10.
[0063] During installation, first insert the gasket body 1 between the joint surface of the upper pull rod 7 and the upper locking nut 9. After the gasket body 1 is inserted into place, use the fixing bolt 5 to connect the fixing part 3 to the upper pull rod 7, or welding can be used to connect. Fold one of the fan-shaped parts 90° to form a limiting part 6, and the limiting part 6 fits the outer hexagon of the upper locking nut 9. At this time, the locking connection is completed. When the limiting part 6 is damaged after long-term use, only another fan-shaped part needs to be used to achieve quick locking. When all the limiting parts 6 are damaged, the fixing bolt 5 can be removed to pull out the gasket body 1, and the locking gasket can be quickly replaced.
[0064] Specifically, the rod cooling bed skirt pull rod utilizes the mechanical anti-loosening principle to significantly improve the anti-loosening effect, effectively solving the problem of the traditional locking method's easy reduction of preload force under complex working conditions such as high temperature, reciprocating motion, and asymmetric cyclic alternating loads, thereby ensuring the long-term stable operation of the pull rod. The U-shaped hollow portion 2 and the fixed portion 3 structure enable the locking gasket to be quickly replaced without disassembling the screw and nut, greatly improving maintenance efficiency and reducing maintenance costs. The locking gasket has a unique and compact structure, and is disc-shaped as a whole. The outer circle is evenly distributed with reusable limiting portions 6, which improves utilization and durability and extends service life.
[0065] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
