Description

Technical Field

[0001] This utility model relates to the field of end cap technology, and in particular to a quick-change end cap. Background Technology

[0002] High-nickel-chromium rolls need to rotate at high speeds during operation and withstand enormous rolling forces, high temperatures, and the impact of cooling media. Therefore, their support and sealing systems are crucial. As one of the key components of the rolls, the end caps (also known as "bearing seats" or "shaft heads") at both ends play a vital role in the rolling process.

[0003] End caps are the connection interface between the rolls and the mill. They are mainly responsible for installing and precisely positioning the rolls on the mill stand and providing necessary support for the rolls. When maintaining the rolls, end caps, as sealing or protective components, need to be frequently disassembled and replaced. Traditional end caps are mainly fixed by bolts and flanges. When replacing them, special tools are needed to tighten or loosen the bolts one by one, which is time-consuming and labor-intensive. Moreover, repeated tightening can easily lead to uneven stress on the sealing gaskets or deformation of the bolt holes.

[0004] Therefore, a quick-change end cap needs to be designed. Utility Model Content

[0005] To overcome the shortcomings of traditional end caps which are mainly fixed by bolts and flanges, requiring special tools to tighten or loosen bolts one by one during replacement, which is time-consuming and labor-intensive, and repeated tightening can easily lead to uneven stress on the sealing gasket or deformation of the bolt holes, this utility model provides a quick-replacement end cap.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a quick-change end cap, comprising a support base and an end cap, with end caps slidably mounted on both sides of the support base. It also includes limit blocks, locking blocks, contact rods, a rotating cover, a limiting ring, and a limiting seat. Multiple limit blocks are fixedly connected to the side of the end cap furthest from the support base. Locking blocks are slidably mounted between adjacent limit blocks. Contact rods are fixedly connected to the side of the locking blocks furthest from the end cap. A rotating cover is rotatably mounted on the side of the end cap furthest from the support base. A guide groove corresponding to the number of contact rods is provided on the rotating cover. The contact rods slide along the guide grooves. A limiting seat corresponding to the number of locking blocks is fixedly connected to the support base. The locking blocks engage with adjacent limiting seats. A limiting ring is fixedly connected to the end cap, located outside the rotating cover.

[0007] As a preferred technical solution of this utility model, it also includes a limiting rod, which is slidably provided on the limiting seat, and a limiting hole is opened on the locking block, with the limiting rod engaging with the adjacent limiting hole.

[0008] As a preferred technical solution of this utility model, it also includes guide pins. Multiple guide pins are fixedly connected to the support base. The end cap is provided with guide holes corresponding to the number of guide pins on the side near the support base. The guide pins slide in adjacent guide holes.

[0009] As a preferred technical solution of this utility model, it also includes a sealing gasket, with the sealing gasket provided between the support base and the end cover, and the guide pin passing through the sealing gasket.

[0010] As a preferred technical solution of this utility model, it also includes a lifting lug, and the lifting lug is fixedly connected to the limiting ring.

[0011] As a preferred embodiment of this utility model, it also includes a handle, with the handle fixedly connected to the side of the rotating cover away from the support base.

[0012] Compared with the prior art, the present invention has the following technical effects: When installing the end cover, by rotating the rotating cover, the contact rod drives the locking block to slide away from the center of the end cover between adjacent limiting blocks. The locking block engages with the limiting seat on the support base to form a mechanical interlock, thereby achieving quick installation. When disassembling the end cover, by rotating the rotating cover in the opposite direction to separate the locking block from the limiting seat, the end cover can be quickly disassembled, thereby enabling quick replacement of the end cover.

Detailed Implementation

[0021] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0022] Example: A quick-change end cap, see reference Figures 1-7 As shown, the device includes a support base 1 and an end cap 2. The end cap 2 is slidably mounted on both sides of the support base 1. It also includes limit blocks 3, locking blocks 4, contact rods 5, a rotating cover 6, a limiting ring 8, and a limiting seat 9. Six limit blocks 3 are circumferentially fixedly connected to the side of the end cap 2 away from the support base 1. Locking blocks 4 are slidably mounted between adjacent limit blocks 3. Contact rods 5 are fixedly connected to the side of the locking blocks 4 away from the end cap 2. A rotating cover 6 is rotatably mounted on the side of the end cap 2 away from the support base 1. The side of the rotating cover 6 away from the support base 1 is welded... The handle 16 is fixedly connected to the rotating cover 6 by gripping the handle 16. The rotating cover 6 has six guide grooves 7. The contact rod 5 slides along the guide grooves 7. The support base 1 has six limit seats 9 fixedly connected to it in the circumferential direction by welding. The locking block 4 is engaged with the adjacent limit seat 9. The end cover 2 is fixedly connected to the limit ring 8. The top of the limit ring 8 is fixedly connected to the lifting lug 15. The lifting lug 15 provides a lifting fulcrum to facilitate the handling of the heavy end cover 2. The limit ring 8 is located on the outside of the rotating cover 6.

[0023] See Figures 1-3 As shown, it also includes a limiting rod 11, which is slidably provided on the limiting seat 9, and a limiting hole 10 is opened on the locking block 4, with the limiting rod 11 engaging with the adjacent limiting hole 10.

[0024] See Figure 6 and Figure 7 As shown, it also includes guide pins 12. Six guide pins 12 are fixedly connected to the support base 1. Six guide holes 13 are opened on the side of the end cap 2 near the support base 1. The guide pins 12 slide in the adjacent guide holes 13.

[0025] See Figure 6 and Figure 7As shown, it also includes a sealing gasket 14, which is provided between the support base 1 and the end cover 2, and the guide pin 12 passes through the sealing gasket 14.

[0026] When installing end cap 2, align end cap 2 with support base 1, aligning the guide hole 13 on end cap 2 with the guide pin 12 on support base 1. Then push end cap 2 to one side of support base 1, sliding it along guide pin 12 towards support base 1 until end cap 2 and support base 1 are tightly fitted. At this time, sealing gasket 14 is compressed to achieve sealing. Then, grasp handle 16 on rotating cover 6 and rotate rotating cover 6. Guide groove 7 on rotating cover 6 pushes contact rod 5 outward. Contact rod 5 drives locking block 4 to slide away from the center of end cap 2 between adjacent limiting blocks 3. Locking block 4 slides outward until it engages with limiting seat 9 on support base 1, forming a mechanical interlock and preventing end cap 2 from axially dislodging from support base 1. Then, push manually. The limiting rod 11 slides along the limiting seat 9 and is inserted into the limiting hole 10 on the locking block 4. This operation prevents the locking block 4 from accidentally retracting. When the end cover 2 needs to be removed, first pull the limiting rod 11 out of the limiting hole 10 to release the additional constraint of the locking block 4. Then rotate the handle 16 on the rotating cover 6 in the opposite direction. The guide groove 7 drives the contact rod 5 to move in the opposite direction. The locking block 4 slides along the track between the limiting blocks 3 towards the center of the end cover 2. The locking block 4 is disengaged from the locking state with the limiting seat 9. After the locking block 4 is fully retracted, the mechanical constraint between the end cover 2 and the support seat 1 is released. At this time, the lifting lug 15 or the end cover 2 body can be pulled directly to make the end cover 2 slide away from the support seat 1 along the guide pin 12, thereby realizing the quick replacement of the end cover 2.

[0027] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
