Description

Technical Field

[0001] This utility model relates to the field of roughing mill work roll guard plate storage technology, specifically to an integrated rack for storing, testing, and maintaining roughing mill work roll guard plates. Background Technology

[0002] The roughing mill work rolls in a steel rolling mill consist of two rolls, an upper roll and a lower roll. They need to be fitted with guard plates before they can be put into operation. The main functions of the guard plates are to guide the slab into the mill, connect the bearing housing, and install scraper blades to protect the rolls.

[0003] Each set of roughing mill work roll guard plates consists of 6 pieces, two of each of three different types. The guard plates must be removed and ground each time the rolls come off the production line, and the scraper blades must be replaced at the same time. After grinding, the guard plates are reinstalled before the rolls are put back on the production line. The disadvantages of existing roughing mill work roll guard plate maintenance techniques are:

[0004] 1. Improperly stacked roughing mill work roll guard plates can damage consumable parts such as scraper blades.

[0005] 2. Roughing mill work roll guard plates are generally used in sets with the rolls; mixing them up will affect the fitting accuracy.

[0006] 3. The roughing mill work roll guard plate needs to be maintained and the scraper blade replaced after each production run, requiring a large workbench.

[0007] The guide surface of the roughing mill work roll guard plate needs to be straight, otherwise it will be difficult to inspect and may lead to defective rolls being put on the production line. Utility Model Content

[0008] The technical problem this utility model aims to solve is that existing roughing mill work roll guard plates are prone to damage from disorderly stacking; they are easily confused when used as a set; maintenance requires a large platform; the guide surface is difficult to inspect for flatness; or they are used on the production line with defects.

[0009] To solve the above problems, the technical solution adopted by this utility model is an integrated frame for storing, inspecting and maintaining roughing mill work roll guards, including a frame structure. The frame structure includes a base frame, a support frame fixed in the middle of the base frame, a second frame fixed in the middle of the support frame, a third frame fixed at the top of the support frame, and a pair of limiting plates fixed in the middle of the top of the support frame. Blocks are fixed at both ends of the base frame, the second frame, and the third frame near one side.

[0010] As a further embodiment of this utility model: a lifting device is placed at the top of the support frame between a pair of limiting plates, which facilitates the storage of the special lifting device.

[0011] As a further embodiment of this utility model: an upper roller lower guard plate, a lower roller upper guard plate, and a lower roller lower guard plate are respectively placed on top of the base frame, frame two, and frame three. The placement of the upper roller lower guard plate, lower roller upper guard plate, and lower roller lower guard plate allows for observation of whether there is a gap between their bottom surfaces and the placement surfaces of the base frame, frame two, and frame three, thereby enabling gap inspection.

[0012] As a further embodiment of this utility model: the lifting device includes a crossbeam, with chains connected to both ends of the crossbeam and boss sleeves connected to the bottom of the chains, which facilitates connection with both ends of the guard plate for easy transport.

[0013] As a further embodiment of this utility model: boss sleeve boxes are fixed at the bottom ends of both sides of the support frame for placing the boss sleeves.

[0014] Compared with the prior art, the advantages of this utility model are as follows: This application can realize the complete storage of roughing mill work roll guard plates, which will not cause cross-contamination and confusion, and can avoid abnormal situations such as changes in guard plate height and gap; after the guard plates are put on the shelf, it can be detected whether they are twisted and whether their flatness is qualified, thus preventing unqualified products from going online; it can make the replacement of scraper blades, springs, bolts and pressure strips more labor-saving, and at the same time has storage, inspection and maintenance functions, which can significantly save space and make the production site neat and orderly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0024] Combined with appendix Figure 1-4 It can be seen that the frame structure includes a base frame 1, a support frame 2 fixed in the middle of the base frame 1, a second frame 3 fixed in the middle of the support frame 2, a third frame 4 fixed at the top of the support frame 2, and a pair of limiting plates 5 fixed at the top middle of the support frame 2. Blocks 6 are fixed at both ends of the base frame 1, the second frame 3, and the third frame 4 near one side.

[0025] A lifting device 7 is placed at the top of the support frame 2 between a pair of limiting plates 5 for easy storage of special lifting devices. The lifting device 7 includes a crossbeam 7.1, with chains 7.2 connected to both ends of the crossbeam 7.1 and a boss sleeve 7.3 connected to the bottom end of the chain 7.2 for easy connection with both ends of the guard plate for easy conveying. The upper roller lower guard plate 8, the lower roller upper guard plate 9, and the lower roller lower guard plate 10 are respectively placed on the base frame 1, the second frame 3, and the third frame 4. The placement of the upper roller lower guard plate 8, the lower roller upper guard plate 9, and the lower roller lower guard plate 10 allows for observation of whether there is a gap between their bottom surfaces and the placement surfaces of the base frame 1, the second frame 3, and the third frame 4, thus enabling gap inspection. Boss sleeve boxes 11 are fixed at the bottom ends of both sides of the support frame 2 for placing the boss sleeve 7.3.

[0026] The working principle of this application is as follows: Base frame 1 provides foundation support: Base frame 1 serves as the bottom support of the entire frame structure, directly contacting the ground and bearing and distributing the weight from the upper components and guardrails; Support frame 2 provides load-bearing and positioning: Support frame 2 has frame two 3 and frame three 4 fixed at its middle and top respectively, forming a stable load-bearing frame. Simultaneously, its top middle limiting plate 5 positions the lifting device 7 to prevent displacement; Lifting device 7 is stored and connected: The lifting device 7 is placed between the top limiting plates 5 of the support frame 2, and is connected via a crossbeam 7.1, a chain 7.2, and a boss. The 7.3 sleeve structure allows for convenient connection with both ends of the guard plate, facilitating subsequent conveying operations. Guard plate placement and gap inspection: The upper roller lower guard plate 8, lower roller upper guard plate 9, and lower roller lower guard plate 10 are placed on the base frame 1, frame 2 3, and frame 3 4 respectively. The gap is checked by observing the gap between the bottom surface of the guard plate and the placement surface to ensure installation accuracy. 7.3 boss sleeve storage: The boss sleeve box 11 at the bottom of both sides of the support frame 2 is used to store the boss sleeve 7.3 on the lifting device 7, so as to keep the accessories in an orderly manner and avoid loss or damage.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
