Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical hot rolling technology, specifically to a descaling box with quick roll changing capability. Background Technology
[0002] Descaling equipment is typically installed on conventional hot rolling mills and medium-thick plate production lines to remove iron oxide scale from the surface of heated slabs. Modern descaling equipment usually uses high-pressure water as the cleaning medium. High-pressure water pumped from the descaling pump station directly impacts the surface of the slab through descaling nozzles, and the iron oxide scale is removed from the surface of the slab through the peeling action of the high-pressure water.
[0003] However, the disadvantage of the traditional structure is that when the rollers are severely worn or the bearings are stuck and the rollers need to be replaced, the cover needs to be removed. This is a very tedious maintenance process that is time-consuming and labor-intensive. Utility Model Content
[0004] To address the aforementioned technical problems, the purpose of this utility model is to provide a descaling box with quick roller replacement, which allows the rollers to be quickly pulled out from the side without removing the box cover, thus solving the problem of long time consumption and high labor intensity when replacing rollers and removing the box cover.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A descaling box with quick roller change capability is characterized by including a bearing housing, which is disposed on the outer side. An opening is provided at the junction of the box cover and the roller body mechanism, and the diameter of the opening is larger than the diameter of the roller. The bearing housing is opened to pull out the roller shaft.
[0006] It also includes a roller body mechanism, which is installed on the roller conveyor frame. The roller body mechanism includes rollers, bearings, and bearing seats. A water baffle is fixedly installed at the junction of the housing and the roller body mechanism with bolts. The rollers are installed in the bearing seats by bearing support.
[0007] The split bearing housing includes a lower housing, an upper cover, and connecting bolts. The upper cover and the lower housing are positioned by a stop, and the upper cover and the lower housing are fixedly connected by connecting bolts.
[0008] The beneficial effects of this utility model are: an opening is provided at the junction of the housing and the roller body mechanism, and the diameter of the opening is larger than the diameter of the roller. The split bearing seat is divided into a lower seat and an upper cover. When the roller needs to be replaced, the housing cover does not need to be disassembled. The roller can be taken out through the opening at the junction of the housing and the roller body mechanism. A water baffle is provided at the opening, which forms a multi-layer labyrinth seal with the roller, achieving a water sealing effect. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0012] like Figure 1 , Figure 2 , Figure 4 As shown, a descaling box with quick roller replacement is characterized by including a bearing seat 4-3, which is disposed on the outer side. An opening is provided at the junction of the box cover 2-2 and the roller body mechanism 4, and the diameter of the opening is larger than the diameter of the roller 4-1. The bearing seat 4-3 is opened to pull out the roller shaft.
[0013] like Figure 2 , Figure 3 As shown, it also includes a roller body mechanism 4, which is installed on the roller conveyor frame 3. The roller body mechanism 4 includes a roller 4-1, a bearing 4-2, and a bearing seat 4-3. A baffle plate 7 is fixedly installed at the junction of the housing 2-2 and the roller body mechanism 4 with bolts 6. The roller 4-1 is supported and installed in the bearing seat 4-3 by the bearing 4-2.
[0014] like Figure 3 As shown, the split bearing housing 4-3 includes a lower housing 4-3-1, an upper cover 4-3-2, and connecting bolts 4-3-3. The upper cover 4-3-2 and the lower housing 4-3-1 are positioned by a stop, and the upper cover 4-3-2 and the lower housing 4-3-1 are fixedly connected by connecting bolts 4-3-3.
[0015] The diameter of the opening at the junction of the box cover 2-2 and the roller body mechanism 4 is larger than the diameter of the roller body of the roller 4-1. Two baffle plates are fixedly connected at this point by bolts 6, forming a multi-maze seal with the roller body mechanism 4 to achieve a water sealing effect. Multiple chains 8 are set along the length of the steel plate to prevent scale water from spraying out of the descaling box.
[0016] When removing roller 4-1, disconnect the connecting bolt 6 of split bearing seat 4-3, open split bearing seat 4-3, and remove the upper cover 4-3-2 and the upper part of bearing 4-2; remove the labyrinth sealing ring (water baffle 7) connected to the box cover 2-2; disconnect from the transmission mechanism 5, lift roller 4-1 slightly, and roller 4-1 can be pulled out from the side of descaling box cover 2-2.
[0017] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
