Description

Technical Field

[0001] This utility model relates to the field of winding device technology, and in particular to a disassembly and assembly structure for a winding device wheel assembly. Background Technology

[0002] The coil receiving device on the thin slab continuous casting and rolling production line is responsible for transferring the steel coils from the No. 1 and No. 2 coilers to the coil transport trolley, and is a key piece of equipment.

[0003] The original design of the wheel system and base was an integral structure. This meant that each time a wheel was replaced, it was necessary to disassemble each component in turn, one by one: the expansion sleeve connecting the reducer and wheel axle, the reducer and motor assembly, the input end embedded bearing housing, the blind end cover, the pressure plate, the blind end embedded bearing housing, the wheel locking sleeve, and so on. Then, they had to be reassembled in reverse order. Moreover, the site structure was compact, and various tools could not be fully utilized. The process generally took more than 8 hours, which was time-consuming and labor-intensive, severely restricting the pace of maintenance and contradicting the concept of sustainable development. Furthermore, if the locking sleeve was not installed accurately when replacing and assembling the wheel, it could easily cause the wheel to shift and rub against the edge after long-term use, resulting in accidents and affecting production efficiency.

[0004] Therefore, it is necessary to propose a disassembly and assembly structure for the wheel assembly of the coiling device to solve or at least alleviate the above-mentioned defects. Utility Model Content

The spacer ring is fitted onto the wheel axle and disposed between the other bearing assembly and the other side of the wheel. The two bearing assemblies are detachably connected to both sides of the base.

[0009] Preferably, each bearing assembly includes a bearing housing, a bearing, and a cap assembly. The bearing is built into the bearing housing and is disposed corresponding to the axle hole. The wheel axle passes through the bearing and the axle hole. One bearing abuts against the outside of the axle shoulder, and the other bearing abuts against the outside of the spacer ring.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a disassembly and assembly structure for a coiling device wheel assembly, including a guide rail assembly, a base mechanism, and two wheel assemblies. The guide rail assembly includes a guide rail frame and multiple interconnected guide rail segments, all of which are detachably mounted. The base mechanism includes a base and two base half-covers. The base has mounting grooves at both ends, and the base half-covers are detachably connected to the ends of the base.

This allows for complete wheel assembly replacement by simply removing the base half-cover and disconnecting the bearing assembly from the base, eliminating the need to disassemble and reassemble each component individually. This significantly improves replacement efficiency and speeds up production recovery. Furthermore, by improving the structure of the wheel's inner hole and removing the locking sleeve, the combined action of the axle shoulder and spacer ring prevents wheel misalignment and avoids wheel slippage, thus preventing accidents.

[0033] Please see the appendix Figure 1-5 The present invention provides a detachable and assembleable structure for a wheel assembly 30 of a winding device, comprising a guide rail assembly 10, a base mechanism 20, and two wheel assemblies 30 arranged opposite to each other along the extending direction of the guide rail assembly 10. The guide rail assembly 10 includes a guide rail frame 110 and multiple sections of interlocking guide rails 120. The guide rails 120 are connected to the guide rail frame 110, and each section of the guide rail 120 is detachably detachable. The specific design is as follows:

[0034] The base mechanism 20 includes a base 210 and two base half-covers 220. The base 210 has mounting grooves 211 at both ends. The base half-covers 220 are detachably connected to the ends of the base 210, and the mating surface between the base half-covers 220 and the ends of the base 210 is an inclined surface. A first semi-circular groove is recessed at the inclined surface of the base 210, and a second semi-circular groove is recessed at the inclined surface of the base half-covers 220. The first and second semi-circular grooves are used to enclose and form a shaft hole 212. Each wheel assembly 30 includes a wheel 310, a wheel axle 320, a spacer ring 330, and two bearing assemblies 34. 0, wherein the wheel axle 320 rotatably passes through the axle hole 212, the wheel 310 is sleeved on the wheel axle 320 and located in the mounting groove 211, the wheel 310 is disposed on the guide rail 120, the wheel axle 320 has a shoulder 321, the shoulder 321 is disposed between one of the bearing assemblies 340 and one side of the wheel 310, the spacer ring 330 is sleeved on the wheel axle 320, the spacer ring 330 is disposed between another bearing assembly 340 and the other side of the wheel 310, and the two bearing assemblies 340 are detachably connected to both sides of the base 210 respectively.

[0035] Specifically, the wheel assembly 30 disassembly and assembly structure of the winding device in this application includes a guide rail assembly 10, a base mechanism 20, and two wheel assemblies 30 arranged opposite each other along the extending direction of the guide rail assembly 10. The guide rail assembly 10 serves as a track for the wheel assembly 30 to move, and includes a guide rail frame 110 and multiple sections of interlocking guide rails 120. The guide rail frame 110 supports the guide rails 120, and each section of the guide rail 120 is detachably spliced. Thus, when the wheel assembly 30 to be replaced is moved to the end guide rail 120, this can be... The end guide rail 120 is detached, thus creating a gap between the wheel assembly 30 and the bottom guide rail frame 110. This gap facilitates the disassembly and assembly of the wheel assembly 30. It is worth mentioning that the guide rail 120, which needs to be replaced frequently, can be in the form of a short rail, which makes disassembly and assembly convenient, and the main body section can use a long rail for better overall rigidity. The upper part of the base mechanism 20 is used for the installation of the winding device. By installing it with the wheel assembly 30, the movement of the wheel assembly 30 along the guide rail 120 drives the winding device connected to the base mechanism 20 to move.

[0036] The base mechanism 20 includes a base 210 and two base half-covers 220. Mounting grooves 211 at both ends of the base 210 are used to place the wheel 310. In this application, the ends of the base 210 are fitted together with the base half-covers 220 to form a complete structure. Thus, when replacing the wheel 310, only the base half-covers 220 need to be removed, instead of disassembling and assembling each component individually as in the prior art. Similarly, the base half-covers 220 also have a groove that connects with the base 210. The corresponding groove in the mounting slot 211 is provided for placing the other half of the wheel 310. Furthermore, the mating surface between the base half-cover 220 and the end of the base 210 is inclined. Thus, when the wheel assembly 30 travels onto the (previously mentioned) short rail, the short rail can be removed first, leaving the wheel assembly 30 suspended. Then, the base half-cover 220 and bearing assembly 340 can be gradually disassembled. As the base half-cover 220 and bearing assembly 340 are disassembled, the wheel assembly 30 will gradually sink to a certain height. After the bearing assembly 340 is completely disassembled, it gradually falls onto the guide rail frame 110 and is then pulled out horizontally. This inclined surface design allows the wheel assembly 30 to slowly sink and then be pulled out horizontally as the fasteners are removed and installed, improving disassembly efficiency while ensuring safety. The angle between the mating surface of the base half-cover 220 and the end of the base 210 and the horizontal plane can be set to 40°–50°. In a preferred embodiment, 45° is used, but those skilled in the art can choose according to specific needs. It is worth noting that the first and second semi-circular grooves are formed at the inclined mating surfaces, so the wheel axle 320 passes through the shaft hole 212 formed by the two. Therefore, after the base half-cover 220 is disassembled, the wheel assembly 30 is only limited by the bearing assembly 340. After disconnecting the bearing assembly 340 from the base 210, the entire wheel assembly 30 can be pulled out directly without disassembling each component individually, thus forming a quick-installation and quick-disassembly structure.

[0037] Furthermore, this quick-installation structure improves the inner bore of the wheel 310 by changing it from a stepped hole to a straight hole, allowing direct installation on the wheel axle 320. This facilitates the installation of a spacer ring 330, which ensures the relative position of mechanical components, such as providing support between the bearing 342 and the wheel 310, preventing axial displacement of the components during operation. Therefore, the spacer ring 330 is positioned between the bearing assembly 340 and one side of the wheel 310; while on the opposite side, the wheel axle 320 itself provides support. The shoulder 321 is positioned between the wheel 310 surface on the opposite side of the spacer ring 330 and another bearing assembly 340, thus forming a bidirectional limit. Under the bidirectional action of the shoulder 321 and the spacer ring 330, the wheel 310 will no longer have the possibility of deviation, and there will be no accident caused by the wheel 310 deviating and rubbing against the edge. In quick installation, after both bearing assemblies 340 are connected to the side wall of the base 210, they can be precisely locked into the shaft hole 212 without protruding outwards. The installation is also matched, and the overall assembly and disassembly are also quick.

[0038] In a preferred embodiment of the present invention, each bearing assembly 340 includes a bearing housing 341, a bearing 342, and a cover assembly. The bearing 342 is built into the bearing housing 341 and is correspondingly disposed with respect to the shaft hole 212. The wheel axle 320 passes through the bearing 342 and the shaft hole 212. One bearing 342 abuts against the outside of the shaft shoulder 321, and the other bearing 342 abuts against the outside of the spacer ring 330. The bearing housing 341 is detachably connected to the side wall of the base 210.

[0039] It should be noted that the bearing 342 is used for the wheel axle 320 to pass through and rotatably connect. To ensure axial bidirectional positioning, the two bearings 342 respectively abut against the axle shoulder 321 and the spacer ring 330. Here, "outer side" refers to the direction from the wheel 310 axially towards both sides. The bearing seat 341 is used for the internal installation of the bearing 342, and by connecting with the base 210, the entire bearing assembly 340 is mounted on the side wall of the base 210. The pressure cap assembly is used to assist the axle... The bearing 342 is positioned and prevents dust. Specifically, it may include an end cap 343 and a through cap 344. The end cap 343 is connected to the end of the wheel axle 320 to ensure that the wheel axle 320 remains stable during operation and prevents its axial movement. It can be bolted to the end of the wheel axle 320. The through cap 344 serves as a seal to prevent dust, water and impurities from entering the bearing housing 341, thereby protecting the bearing 342 and other key components and extending their service life. It is bolted to the inside of the bearing housing 341.

[0040] In a preferred embodiment of the present invention, the bearing housing 341 includes a flange section 3411 and an extension section 3412. The extension section 3412 is embedded in the shaft hole 212. The flange section 3411 protrudes radially from the outer end of the extension section 3412. The flange section 3411 is connected to the side wall of the combined base 210 and the base half cover 220 by bolts.

[0041] It should be noted that the extending section 3412 is used to embed into the shaft hole 212, so that the shaft shoulder 321 and the spacer ring 330 are also built into the shaft hole 212, without protruding outwards; while the flange section 3411 serves as a connector, allowing for disassembly and connection via bolts; it is worth mentioning that, during installation, the coverage area of ​​the flange section 3411 includes the side walls of the base 210 and the base half-cover 220, that is, the flange section 3411 is bolted to the base 210 and the base half-cover 220 respectively. 10. The side wall connection of the base half cover 220 can improve the overall connection between the bearing assembly 340, the base 210, and the base half cover 220, ensuring overall rigidity during normal use. At the same time, this connection method can also protect the wheel assembly 30 during disassembly. During disassembly, the bolts of the base half cover 220 and the flange section 3411 can be gradually loosened, so that the wheel assembly 30 sinks to a certain height first, instead of falling directly onto the guide rail frame 110, thereby protecting the wheel assembly 30 and extending its service life.

[0042] Furthermore, each wheel assembly 30 also includes a retaining ring 350, which is sleeved on the wheel axle 320 and disposed between the spacer ring 330 and the bearing 342.

[0043] It should be noted that the retaining ring 350 has reliable fixing and limiting functions to further ensure that the various components of the wheel assembly 30 remain stable during operation, thereby improving driving safety and reliability.

[0044] Furthermore, it also includes a lifting cylinder, which is connected to the guide rail 120 and disposed between the guide rail 120 and the base 210.

[0045] It should be understood that the lifting cylinder (not shown in the figure) can lift the entire base 210 (including the wheel assembly 30 and the base half cover 220 mounted on the base 210) to a certain height before disassembly, so that the wheel assembly 30 has more height space after the short rail is disassembled, which facilitates the disassembly and assembly operations of technicians.

[0046] Furthermore, the base half cover 220 is also provided with a relief groove 221. The relief groove 221 has a chamfered surface that is parallel to the inclined surface of the base half cover 220. The base half cover 220 is connected to the base 210 by bolts passing through the chamfered surface and extending into the base 210.

[0047] It should be noted that the clearance groove 221 can be used to form a beveled surface, which is matched and parallel to the inclined surface of the base half cover 220, so that the bolts that are screwed in are perpendicular to the inclined surface of the base half cover 220 to ensure a stable connection. At the same time, the opening space formed by the clearance groove 221 can also facilitate the operation of technicians.

[0048] Furthermore, one end of the wheel axle 320 in one of the wheel assemblies 30 extends out of the bearing assembly 340.

[0049] It is understandable that the entire device can be moved by driving only one wheel assembly 30 to rotate, i.e., one side is the driving wheel and the other side is the driven wheel. Thus, one end of the wheel axle 320 of one side is extended out of the bearing assembly 340 so as to connect with the drive assembly, so as to drive it to rotate through the drive assembly and thus move the entire device.

[0050] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
