Description

Technical Field

[0001] The utility model relates to the technical field of position detection, in particular to a width measuring device of medium and thick plate shot blasting equipment. Background Art

[0002] Steel plates with a thickness of more than 4mm are called medium and thick plates, or medium and thick plates for short. At present, the production of medium and thick plates mostly adopts the controlled rolling production process. Before rolling, the oxide scale on the steel plate is mostly cleaned by shot blasting. Since the width range of steel plates in steel mills varies greatly, and the width of the shot blasting equipment is customized according to the maximum size, there is no effective width measuring device, so the shot blasting equipment is often in the empty shot blasting phenomenon, which damages the protective plate of the shot blasting equipment. Most of the equipment in the steel mill rolling process runs continuously without stopping. In the shot blasting process, the width measuring device is particularly important.

[0003] Existing shot blasting equipment, such as the prior art with application number CN201620985107.0, includes a shot blasting chamber, a shot blasting wheel, a main conveying roller, an annular groove, an auxiliary conveying roller and a steel plate. At least two shot blasting wheels are installed in the shot blasting chamber, and the shot blasting wheels perform shot blasting on the two surfaces of the steel plate leaning against the main conveying roller.

[0004] However, the width measuring devices in the prior art mostly adopt the method of photoelectric switches. However, the adverse factors such as the harsh environment, dust interference, and continuous operation during the rolling process of the steel mill lead to empty casting, which reduces the practicality.

[0022] The feeding mechanism 01 is used to feed and transport the medium and thick plates, the sensing mechanism 04 provides detection, and the counterweight mechanism 03 provides counterweight for the width measuring mechanism 02, and the width measuring mechanism 02 detects the width of the medium and thick plates;

[0023] The feeding mechanism 01 includes a bottom plate 11, a plurality of first mounting frames 12, a plurality of first rotating shafts 13 and a plurality of power transfer rollers 14. The plurality of first mounting frames 12 are all mounted on the top of the bottom plate 11. The plurality of power transfer rollers 14 are rotatably mounted on the first mounting frames 12 via the first rotating shafts 13.

[0024] The width measuring mechanism 02 includes a second mounting frame 21, a second rotating shaft 22, a sensing roller bracket 23 and a sensing roller 24. The second mounting frame 21 is mounted on the top of the bottom plate 11. The second mounting frame 21 is located between the first mounting frames 12. The sensing roller bracket 23 is rotatably mounted on the second mounting frame 21 through the second rotating shaft 22. The sensing roller 24 is rotatably mounted on one end of the sensing roller bracket 23.

[0025] The counterweight mechanism 03 includes a counterweight rod 31, a fixing bolt 32, a rotating frame 33 and a counterweight block 34. The counterweight rod 31 is mounted on the induction roller bracket 23 through the fixing bolt 32. The rotating frame 33 is rotatably mounted on the counterweight rod 31. The counterweight block 34 is mounted on the bottom end of the rotating frame 33.

[0026] The sensing mechanism 04 includes a sensing block 41 and a proximity switch 42. The proximity switch 42 is mounted on the bottom plate 11, and the sensing block 41 is mounted on the second rotating shaft 22.

[0027] The medium and thick plate is placed on the power transfer roller 14, and the rotation of the first rotating shaft 13 drives the power transfer roller 14 to rotate, thereby driving the transportation and feeding of the medium and thick plate. When the medium and thick plate is not in contact with the induction roller 24, the counterweight of the counterweight block 34 makes the induction roller 24 higher than the power transfer roller 14. At this time, the induction block 41 is away from the proximity switch 42. When the medium and thick plate is transported and contacts the induction roller 24, the medium and thick plate is in contact and squeezed with the induction roller 24, thereby making the induction roller bracket 23 rotate, thereby pressing the induction roller 24 under the power transfer roller 14. At this time, the induction block 41 rotates to a position close to the proximity switch 42, and then sends an electrical signal through the proximity switch 42 to control the shot blasting gate at the corresponding position to open.

When the medium and thick plate is not in contact with the induction roller 24, the induction roller 24 is made higher than the power transfer roller 14 by the counterweight of the counterweight block 34. At this time, the induction block 41 is away from the proximity switch 42. When the medium and thick plate is transported and contacts the induction roller 24, the medium and thick plate is contacted and squeezed with the induction roller 24, thereby making the induction roller The bracket 23 rotates, thereby pressing the induction roller 24 under the power transfer roller 14.
