Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of bearing equipment, and particularly relates to an auxiliary device for troubleshooting. BACKGROUND

[0002] In the metallurgical industry, the normalizing and pickling unit is the first process in the cold rolling process of high-grade non-oriented silicon steel and oriented silicon steel products. The main function of the loop section of the unit is to store and release the strip steel through intermittent filling and releasing of the loop, so as to form a "buffer zone" between the entry and exit sections and the process treatment section, thereby effectively ensuring the continuous operation of the process section when the entry and exit sections are stopped.

[0003] The normalizing and pickling unit is designed to have seven strip steel support trolleys in the loop section. Each trolley has six support rollers, and the specifications of the support rollers are mostly 150mm*1800mm. Bearings are provided on both sides of the roller and embedded in the roller. During the operation of the production line, the strip steel tension at the inlet loop is large (about 40KN). The support rollers are subjected to the horizontal tension of the strip steel for a long time. During the filling and releasing of the loop, the speed of the support rollers of the loop trolley changes frequently, and the bearing load is large. During the operation, the support roller bearing frequently fails, and the support roller is blocked after the bearing is damaged, which causes scratches on the surface of the strip steel and quality defects.

[0004] During the production of the loop section, the space is narrow due to the limitation of the strip steel, and the height difference between the topmost support roller and the ground is about 9 meters. The replacement operation during the replacement operation takes a long time and is low in efficiency, which affects the operation of the unit. SUMMARY

Figure 3 A structure diagram of the auxiliary device for troubleshooting in one or more embodiments of the present application is shown. Figure 2 A structure diagram of the auxiliary device for troubleshooting in one or more embodiments of the present application is shown.

[0027] Please refer to Figures 1-3The first aspect embodiment of the application provides a troubleshooting auxiliary device arranged at the supporting roller 1 of the supporting trolley of the design loop section of the normalizing and pickling unit. The troubleshooting auxiliary device comprises a supporting frame 2, two supporting seats 4 and two bearing seats 3. The supporting frame 2 comprises two oppositely arranged columns 21, and the two columns 21 are respectively located on the left and right sides of the supporting trolley, and the spacing between the two columns 21 is greater than the length of the supporting roller 1 on the supporting trolley. In order to further improve the accuracy of the spacing between the two columns 21, a connecting rod 22 is fixedly arranged between the two columns 21, so as to improve the anti-deformation ability of the whole supporting frame 2 and ensure the accuracy of the spacing between the two columns 21.

[0028] The two supporting seats 4 are respectively arranged on one side wall of the two columns 21, and the position of the supporting seat 4 is higher than that of the supporting roller 1 on the supporting trolley. The height of the supporting seat 4 relative to the ground can be personalized according to the specifications of the supporting trolley.

[0029] One column 21 is provided with one supporting seat 4, and the two supporting seats 4 are oppositely arranged. Referring to Figure 1 The supporting seat 4 comprises a supporting plate 41, and one end of the supporting plate 41 is fixedly connected with the supporting seat 4. The bearing seat 3 is provided with a mounting hole 34, and the bearing seat 3 is sleeved with the other end of the supporting plate 41 through the mounting hole 34. Meanwhile, the bearing seat 3 is detachably connected with the supporting plate 41 through clamping or bolt connection, so as to facilitate the installation of the bearing seat 3 or the maintenance of the bearing seat 3.

[0030] The two bearing seats 3 are respectively arranged on the two supporting seats 4, and the axes of the bearings 32 of the two bearing seats 3 are located on the same straight line. It can be understood that the two bearing seats 3 are respectively used for connecting with the two ends of the supporting roller 1. When the supporting roller 1 needs to be repaired or replaced, the operating personnel dismounts the supporting roller 1 from the supporting trolley and hoists it to the troubleshooting auxiliary device, so that the shaft heads of the two ends of the supporting roller 1 can be respectively connected with the two bearing seats 3 of the troubleshooting auxiliary device. In the process of matching the bearing seat 3 with the two ends of the supporting roller 1, first, the two bearing seats 3 are sleeved on the supporting plate 41, and the spacing between the two bearing seats 3 is greater than the length of the supporting roller 1. After the supporting roller 1 is hoisted, one end of the supporting roller 1 is connected with one bearing seat 3, and then the other end of the supporting roller 1 is moved to above the supporting plate 41, and the operating personnel pushes the bearing seat 3 to match with the supporting roller 1. While the old supporting roller 1 is hoisted, the new supporting roller 1 can be installed on the supporting trolley, which greatly improves the operation efficiency of replacing the supporting roller 1.

[0031] When the support roller 1 is already on the troubleshooting auxiliary device, the old support roller 1 is removed, and the existing support roller 1 is taken off from the troubleshooting auxiliary device and hoisted to the lower side by the hoisting device, and then transported away. The hoisting device is also located at the lower side after being removed, and the work personnel can connect the just removed support roller 1 with the hoisting device. That is, the troubleshooting auxiliary device can realize multiple operations at the same time, and improve the overall disassembly efficiency.

[0032] In some embodiments, the support plate 41 is horizontally arranged to provide upward support force for the bearing seat 3, and facilitate the cooperation between the bearing seat 3 and the support plate 41.

[0033] In some embodiments, the support seat 4 further comprises a support rib plate 42, which is arranged below the support plate 41, one side of the support rib plate 42 is fixedly connected with one side of the stand column 21, and the other side of the support rib plate 42 is fixedly connected with the bottom surface of the support plate 41. That is, the support rib plate 42 provides greater support force for the support plate 41, avoids deformation of the support plate 41, and improves the safety performance of the entire troubleshooting auxiliary device during use.

[0034] In some embodiments, the support rib plate 42 is vertically arranged, and the stand column 21 is also vertically arranged. At this time, the support efficiency of the support rib plate 42 to the support plate 41 is the highest. Of course, a plurality of support rib plates 42 can be arranged between the support plate 41 and the stand column 21 to improve the strength of the support plate 41, as long as the support rib plate 42 does not affect the cooperation between the bearing seat 3 and the support plate 41.

[0035] Referring to Figures 1-3 , the bearing seat 3 comprises a seat body 31 and a bearing 32 arranged on the seat body 31, and a mounting hole 34 is arranged below the bearing 32. That is, in use, the support roller 1 is placed on the support plate 41 rather than hoisted on the support plate 41, and the safety factor is higher.

[0036] Referring to Figures 1-3, the bottom end of the seat body 31 is provided with two oppositely arranged embracing arms, the two embracing arms are a first embracing arm 35 and a second embracing arm 36, one end of the first embracing arm 35 is fixedly connected with one end of the bottom surface of the seat body 31, the other end of the first embracing arm 35 is fixedly connected with one end of the second embracing arm 36, the two embracing arms enclose to form a mounting hole 34, wherein the two second embracing arms 36 are horizontal and not connected, in the process of sleeving the bearing 32 on the support plate 41, the support rib plate 42 can pass through the gap between the two second embracing arms 36, at this time the support rib plate 42 can not only provide more comprehensive support for the support plate 41, but also provide a certain guiding function for the bearing 32, that is, the two embracing arms reduce the difficulty of cooperation between the bearing seat 3 and the support plate 41, and because the mounting hole 34 is located below the bearing 32, in the use process, the gravity of the support roller 1 is transferred to the support plate 41, the support rib plate 42 and the stand 21 through the bearing seat 3, and will not cause too much pressure on the two embracing arms, and the two embracing arms are not easy to deform.

[0037] In some embodiments, the shape of the mounting hole 34 matches the shape of the support plate 41, so as to reduce the movement of the bearing seat 3 compared to the support plate 41, and improve the safety performance of the entire troubleshooting auxiliary device.

[0038] Referring to Figure 2 , at least one through hole is arranged on each of the two second embracing arms 36, and a corresponding screw hole is arranged on the support plate 41, the bearing seat 3 and the support plate 41 are detachably connected together by bolt connection, in the process of connecting the support roller 1 with the bearing seat 3, one bearing seat 3 can be connected with the support plate 41 by bolt connection first, after one end of the support roller 1 is connected with the bearing seat 3, the other end of the support roller 1 is connected with another bearing seat 3, and then the other bearing seat 3 is connected with the corresponding support plate 41.

[0039] In some embodiments, the strip-shaped hole 37 is a strip-shaped hole 37, the length direction of the strip-shaped hole 37 is perpendicular to the axis of the bearing 32, which greatly reduces the difficulty of using bolts and improves the efficiency of disassembling and assembling the support roller 1.
