Description

Technical Field

[0001] This invention belongs to the field of steel rolling production, and in particular relates to heat insulation covers for hot-rolled steel strips. Background Technology

[0002] In recent years, my country's steel product market has undergone significant changes. A few years ago, the hot-rolled strip steel market, especially the medium and narrow strip steel market, was extremely hot. During the production process, because the insulation cover is located after the heating furnace in the production line, the steel billet is at an excessively high temperature when passing through the insulation cover after exiting the heating furnace. The insulation cover plate will deform and be damaged due to the high temperature. Furthermore, because the insulation cotton filling inside the insulation cover is soft, the studs used in the existing insulation covers may not be able to be stably connected during the connection process. Summary of the Invention

[0003] In view of this, the present invention aims to provide a heat insulation cover for hot-rolled steel strip, in order to solve at least one of the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] Insulation covers for hot-rolled steel strip include:

[0006] The guard plate has its edge bent downwards to form an inverted U-shaped structure covering the roller conveyor. A connecting plate is fixedly provided on the outer wall of the guard plate, and the connecting plate is fixedly connected to the power output end of the drive assembly used to drive the heat insulation cover to tilt.

[0007] The splicing panel consists of multiple panels that are sequentially connected to the inner side of the protective panel, forming a filling cavity between the panels and the protective panel. The filling cavity is filled with a filler material for heat insulation.

[0008] Furthermore, the splicing plate has a first fixing hole, and a fixing bolt is provided in the first fixing hole. The protective plate has a second fixing hole corresponding to the fixing bolt. The fixing bolt passes through the first fixing hole and the second fixing hole in sequence and is threadedly connected to the fixing nut located outside the second fixing hole. The nut part of the fixing bolt is pressed against the splicing plate, and the fixing nut is pressed against the protective plate.

[0009] Furthermore, the screw portion of the fixing bolt consists of a support section and a connecting section, wherein the axis of the support section is collinear with the axis of the connecting section, and the diameter of the support section is larger than the diameter of the connecting section;

[0010] The end face of the support section's top-tightening guard plate is close to the splicing plate. The outer wall of the connecting section has an external thread corresponding to the internal thread of the fixing nut. The fixing nut is threadedly connected to the part of the connecting section located outside the filling cavity.

[0011] Furthermore, the inner diameter of the first fixing hole is larger than the diameter of the support section, and the inner diameter of the first fixing hole is smaller than the diameter of the fixing bolt nut.

[0012] The inner diameter of the second fixing hole is larger than the diameter of the connecting section, and the inner diameter of the second fixing hole is smaller than the outer diameter of the fixing nut.

[0013] Furthermore, the splicing portions of two adjacent splicing panels overlap each other, and the fixing bolts pass through the first fixing holes on the two splicing panels;

[0014] The splicing panel has a double-layer structure with a gap between the two layers, and one layer of the splicing panel is inserted into the gap between the adjacent splicing panels.

[0015] Furthermore, the connecting plate is fixedly connected to one side of the outer wall of the protective plate, and a support plate is provided on the top of the protective plate. One end of the support plate is fixedly connected to the connecting plate, and one side of the support plate is fixedly connected to the protective plate. The connecting plate, the protective plate, and the support plate are perpendicular to each other.

[0016] Furthermore, the connecting plate and the driving assembly are connected via a linkage component, which includes:

[0017] A support frame, which is disposed on one side of the roller conveyor and fixed to the ground;

[0018] The linkage plate has its middle part hinged to the top of the support frame. One end of the linkage plate is hinged to the power output end of the drive component, and the other end is fixedly connected to the connecting plate.

[0019] Furthermore, the housing of the drive assembly is hinged to the support frame.

[0020] Compared with the prior art, the thermal insulation cover for hot-rolled steel strip described in this invention has the following advantages: the multiple spliced ​​plates stacked in sections will deform in a staggered manner when subjected to high temperature, preventing bulging and damage; the fixing bolts and fixing nuts fix the spliced ​​plates and the protective plate together, greatly increasing the stability of the thermal insulation cover; during the fixing process, the supporting section of the fixing bolts will support the thermal insulation cotton layer, thus making the connection more secure.
