Description

Technical Field

[0001] This utility model relates to the field of scrap steel transportation technology, and in particular to a device for intercepting bulging slabs at the entrance of a descaling box. Background Technology

[0002] During hot rolling, slabs are prone to defects such as inclusions, segregation, and bubbles in the raw materials during heating and rolling, or deformation due to uneven heating, resulting in localized bulges. When a slab with bulges is conveyed to the descaling box inlet, if the bulge height exceeds the preset height of the high-pressure descaling water manifold inside the descaling box, the bulge will directly impact the nozzles on the manifold, causing nozzle damage, manifold deformation, and other equipment malfunctions. In severe cases, the bulging slab may even get stuck inside the descaling box, causing production line shutdowns, affecting production continuity, and increasing maintenance costs.

[0003] Currently, there is a lack of specialized preventative measures for damage to descaling equipment caused by bulging of slabs. Most of the time, we rely on manual inspections or subsequent shutdowns for maintenance, which makes it difficult to intercept bulging slabs in time before they enter the descaling box and thus cannot prevent the above problems from the source.

[0004] Therefore, it is necessary to propose a descaling box inlet bulge slab interception device to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0036] Please see the appendix Figure 1-4This utility model provides an embodiment of a descaling box inlet bulging slab interception device, comprising a first support mechanism 10, a second support mechanism 20, and a bulging stop mechanism 30. First, it should be noted that in this application, "longitudinal" refers to the conveying direction of the slab, and "transverse" refers to the axial direction of the roller conveyor. Please refer to the accompanying drawings for details; the specific scheme is as follows:

[0037] The bulge stop mechanism 30 includes a mounting plate 310, a limit switch 320, and a bulge stop assembly. The first support mechanism 10 includes two support units arranged laterally opposite each other. The second support mechanism 20 is longitudinally spaced on one side of one of the support units. The mounting plate 310 is connected to the second support mechanism 20 and is vertically adjustable. The limit switch 320 is connected to the mounting plate 310 and is vertically adjustable. The bulge stop assembly includes a height limiting part 330 and a sensing part 340. The height limiting part 330 is spaced above the roller conveyor to abut against the bulge of the slab. The height limiting part 330 is horizontally placed between the two support units and is vertically movable. The sensing part 340 is fixed to the end of the height limiting part 330 near the limit switch 320. The limit switch 320 is electrically connected to the roller conveyor.

[0038] Specifically, the descaling box inlet bulge slab interception device in this application includes a first support mechanism 10, a second support mechanism 20, and a bulge stop mechanism 30. The bulge stop mechanism 30 includes a mounting plate 310, a limit switch 320, and a bulge stop assembly. The first support mechanism 10 is used for mounting and connecting the bulge stop assembly, and the second support mechanism 20 is used for connecting the mounting plate 310. The mounting plate 310 is used for mounting the limit switch 320, and the limit switch 320 cooperates with the bulge stop assembly to switch the switching state, thereby realizing the switching between roller conveyor operation and stop. Therefore, the limit switch 320 is electrically connected to the roller conveyor.

[0039] The bulge stop assembly includes a height limiting part 330 and a sensing part 340. The height limiting part 330 is spaced above the roller conveyor to form a gap. This gap allows normal slabs or slabs entering the descaling box to pass through. The gap height is the height of the bulge, which can be set with reference to the position of the nozzle of the descaling box manifold. Therefore, considering the stable installation of the height limiting part 330, the first support mechanism 10 includes two support units arranged laterally opposite each other, such that the two support units are located on both sides of the roller conveyor. The height limiting part 330 is placed horizontally between the two support units and is vertically movable so as to be lifted when it comes into contact with the bulge of the slab. The sensing part 340 is fixed on the height limiting part 330 to move with the height limiting part 330. It is located at one end near the limit switch 320 so as to facilitate proximity sensing with the limit switch 320.

[0040] When the sensing unit 340 is within the sensing range of the limit switch 320, typically in the initial setting position, the limit switch 320 is in the open state controlling the operation of the roller conveyor. The slab is normally conveyed towards the descaling box on the roller conveyor. Slabs that meet specifications or do not affect entry into the descaling box (minor bulges are negligible) pass normally through the gap between the height limiting part 330 and the roller conveyor. However, when a bulging slab (the bulge height is greater than the gap between the height limiting part 330 and the roller conveyor) pushes up the height limiting part 330, it causes the sensing unit 340 to disengage from the limit switch 320. When the sensing range is 0, the limit switch 320 is in the closed state to stop the roller conveyor. At this time, the slab stops being conveyed, and technicians can deal with the bulging slab in time. After the slab is repaired, it can pass normally through the bottom of the height limit part 330. The sensing part 340 returns to the sensing range of the limit switch 320, the limit switch 320 returns to the open state, and the roller conveyor resumes operation to continue conveying the slab. It is worth mentioning that, in a preferred embodiment of this application, the limit switch 320 can be an electromagnetic induction proximity switch, which is triggered by the change in electromagnetic field caused by the approach of a metal target object.

[0041] It should be noted that if the bulge is too large to lift the height limit section 330, the slab will be stuck. Usually, the processing plant will set up HMD tracking for slab shadow tracking. In this way, if the slab does not move into place for a long time, an abnormal alarm will be triggered as an additional early warning method for handling bulging slabs. This is a technical content well known to those skilled in the art, and will not be described in detail here.

[0042] In a preferred embodiment of the present invention, each of the support units includes a first base 110 and a first channel steel 120. The first base 110 is used to be welded to the workbench, and the first channel steel 120 is vertically connected to the first base 110. The height limiting part 330 is horizontally placed between the first channel steels 120 of the two support units.

[0043] It should be noted that the first base 110 is used to fix to the workbench to ensure the stability of the support of the first channel steel 120. The channel steel is easy to install and weld, and its recessed space is easy to process and also convenient for the installation of other components, so that the height limiting part 330 is placed horizontally between the first channel steel 120 of the two support units.

[0044] In a preferred embodiment of this utility model, the height limiting part 330 includes a horizontal tube 331 and two fixing plates 332 arranged laterally opposite each other, and the sensing part 340 includes a stop 341; wherein, the first channel steel 120 is provided with a clearance hole 121 for the horizontal tube 331 to pass through, the two fixing plates 332 are respectively fixed to both ends of the horizontal tube 331, and the fixing plates 332 are vertically movably connected to the first channel steel 120, and the stop 341 is fixed to the fixing plate 332 near the limit switch 320.

[0045] It should be noted that the height limiting part 330 adopts a combination of a horizontal tube 331 and two fixing plates 332. The horizontal tube 331 is used to abut against the bulge of the slab. The fixing plates 332 are welded to both ends and are slidably connected to the first channel steel 120 vertically through the fixing plates 332. The clearance hole 121 on the first channel steel 120 is used for the horizontal tube 331 to pass through. Considering that the bulge needs an upward force to push up the horizontal tube 331, the horizontal tube 331 is preferably a round tube. The inclined force generated by the contact with the arc surface of the round tube has a partial upward component, thereby gradually pushing up the horizontal tube 331. As the conveying process progresses... After entering, it rises higher and higher until it finally disengages from the limit switch 320, thus shutting off the roller conveyor. The sensing part 340 uses a stop 341, which can be fixed to the fixing plate 332 by welding. The stop 341 can adapt well to the sensing target of the electromagnetic induction proximity switch, ensuring good sensing effect. It is worth mentioning that, preferably, the cross-section of the fixing plate 332 is U-shaped, and the opening of the fixing plate 332 is set away from the horizontal tube 331. In this way, one end of the fixing plate 332 opening faces the limit switch 320, and the stop 341 is fixed at the opening end of the fixing plate 332, which is convenient for installation and processing.

[0046] In a preferred embodiment of this utility model, four reset units 350 are also included. The clearance hole 121 is an elongated hole extending vertically. Each of the first channel steels 120 has a first elongated hole 122 extending vertically on both sides, and each of the first elongated holes 122 is provided with a reset unit 350. Each reset unit 350 includes a mounting base 351 and a reset spring 352. The mounting base 351 is fixed to the bottom of the first elongated hole 122. The bottom end of the reset spring 352 is connected to the mounting base 351. The fixing plate extends outward along both sides in the longitudinal direction to form a sliding rod 333. The sliding rod 333 passes through the first elongated hole 122 and is slidably arranged vertically. The top end of the reset spring 352 is connected to the sliding rod 333.

[0047] It is worth noting that the reset unit 350 is used to reset the bulge stop assembly after it has been lifted, so that it is reset to the sensing range of the limit switch 320. The first elongated holes 122 on both sides of each of the first channel steels 120 are used for the sliding rods 333 protruding from both ends of the fixing plate to pass through, thereby realizing vertical guiding sliding. In the initial state, it is supported by the reset unit 350 to be supported within the sensing range of the limit switch 320. The four first elongated holes 122 correspond to four reset units 350. Each reset unit 350 includes a mounting base block 35. 1 and a return spring 352, wherein the mounting base 351 is used for mounting the return spring 352, which is fixed to the bottom of the first elongated hole 122 for support, and the return spring 352 is connected between the mounting base 351 and the slide rod 333 of the fixed plate, so that it is supported at the height position of the sensing range of the limit switch 320 under the initial support of the return spring 352. After being lifted by the bulging slab, the spring is stretched. After the bulging slab is processed and normal passage is restored, it retracts to the initial support position under the action of the return spring 352, and the roller conveyor operates normally.

[0048] In a preferred embodiment of the present invention, the second support mechanism 20 includes a second base 210 and a second channel steel 220. The second base 210 is welded to the workbench, the second channel steel 220 is vertically connected to the second base 210, and the mounting plate 310 is connected to the second channel steel 220.

[0049] It is worth noting that, similar to the first support mechanism 10, the second base 210 is also used to fix to the workbench to ensure the stability of the support of the second channel steel 220. The channel steel is easy to install and weld, and its recessed space is easy to process. The mounting plate 310 extends longitudinally, and one end of it is installed and connected to the second channel steel 220.

[0050] Furthermore, the second channel steel 220 has a second elongated hole 221 extending vertically, and the mounting plate 310 is connected to the second channel steel 220 in an adjustable vertical position by means of bolts passing through the second elongated hole 221 and a nut.

[0051] It should be noted that by using a second elongated hole 221 to adjust the vertical position of the mounting plate 310, it is easy to adjust the vertical position of the limit switch 320 to adjust the preset height according to different application scenarios. After adjustment, it can be fixed by bolts. Simultaneously, the height of the entire bulge stop assembly can be adjusted by adjusting the initial support height of the spring. Thus, the applicability of the entire device is high, and it can use slabs of different specifications and thicknesses.

[0052] Furthermore, the mounting plate 310 has a longitudinal elongated hole 311, and the limit switch 320 is connected to the longitudinal elongated hole 311 so as to be adjustable in the longitudinal position.

[0053] It should be understood that the longitudinal elongated hole 311 of the mounting plate 310 is used to adjust the longitudinal position of the limit switch 320. It is usually suitable for scenarios where the position of the first support mechanism 10 is inconvenient to install. After installation according to the actual site environment, the limit switch 320 can be adjusted and fixed in a suitable position so that it can sense the stop 341.

[0054] 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.
