Inspection protector and cold rolling reversible mill assembly

Abstract

According to the inspection protection tool and the cold-rolling reversible mill assembly, a V-shaped body is arranged on a cold-rolling thin strip steel in a sleeving mode from the side face of the cold-rolling thin strip steel, and one side of the V-shaped body can be supported on the upper surface of the cold-rolling thin strip steel. When an inspector inspects the upper surface of the cold-rolled thin strip steel from the side face of the cold-rolled thin strip steel, the V-shaped body with the thickness larger than that of the cold-rolled thin strip steel isolates the body of the inspector from the side face of the cold-rolled thin strip steel and effectively protects the body of the inspector. And the potential safety hazard that inspectors are cut by the cold-rolled thin strip steel in the inspection process is reduced. The positioning mechanism is hinged to one end of the V-shaped body, and the clamping pieces are hinged to the two sides of the V-shaped body respectively and can be matched through buckles to clamp the cold-rolled thin strip steel, so that the position, relative to the cold-rolled thin strip steel, of the V-shaped body is stable, and inspection personnel and the cold-rolled thin strip steel are effectively isolated. The problem that potential safety hazards exist during thin strip steel surface quality inspection is solved.

Description

Technical Field

[0001] This application belongs to the technical field of rolling equipment, and particularly relates to an inspection guard and a cold rolling reversible mill assembly. Background Art

[0002] Cold-rolled thin steel plate is short for cold-rolled plate of ordinary carbon structural steel. Due to its good surface quality and dimensional accuracy, cold-rolled thin steel plates are widely used in the preparation of various machines. Before and after each rolling pass and before the thin strip steel is coiled offline, it is necessary to stop the machine to check the surface quality of the thin strip steel, and then decide whether the thin strip steel continues to be rolled or stays according to its surface quality.

[0003] In the prior art, the surface quality of the thin strip steel is inspected manually. When the thin strip steel is being rolled, it has a certain height and may need to continue rolling. Inspectors can only detect it from the upper side of the thin strip steel. Since the thin strip steel is relatively thin and its side edges are sharp, it is easy to cut the inspectors, posing a safety hazard. Utility Model Content

[0004] This application provides an inspection guard and a cold rolling reversible mill assembly, aiming to solve the problem of potential safety hazards to a certain extent when inspecting the surface quality of thin strip steel.

[0005] In the first aspect of this application, an inspection guard is provided for inspecting the surface quality of cold-rolled thin strip steel, including:

[0006] A V-shaped body for sleeving on the cold-rolled thin strip steel to isolate the side surface of the cold-rolled thin strip steel, and its thickness is greater than that of the cold-rolled thin strip steel;

[0007] A positioning mechanism hinged to one end of the V-shaped body, including at least two clamping members respectively hinged to both sides of the V-shaped body. The at least two clamping members are in snap-fit with each other, and the clamping members in snap-fit are used to clamp the cold-rolled thin strip steel.

[0008] In some embodiments, the included angle corresponding to the V-shaped body is 20° to 60°.

[0009] In some embodiments, the clamping member is provided with an arc-shaped clamping surface for contacting the cold-rolled thin strip steel.

[0010] In some embodiments, one positioning mechanism is respectively hinged to both ends of the V-shaped body.

[0011] In some embodiments, the inspection guard further includes:

[0012] A roller rotatably connected to the V-shaped body, and its axis extends along the width direction of the cold-rolled thin strip steel.

[0013] In some embodiments, the V-shaped body is provided with a mounting groove, and the roller is rotatably connected to the side wall of the mounting groove.

[0014] In some embodiments, the V-shaped body is further provided with an observation groove on the same side as the roller and spaced from the roller.

[0015] In a second aspect of the present application, there is provided a cold rolling reversible mill assembly, comprising:

[0016] A cold rolling reversible mill;

[0017] Equipment adjacent to the cold rolling reversible mill, and the distance between the equipment and the cold rolling reversible mill is 3.5 m to 4.5 m;

[0018] The inspection protective device as described above is located between the equipment and the cold rolling reversible mill and is used to sleeve the cold rolled thin strip steel.

[0019] In some embodiments, the ratio of the distance to the length of the V-shaped body is 2.5:1 to 3.75:1.

When the inspector inspects the upper surface of the cold rolled thin strip steel from the side, the V-shaped body with a thickness greater than that of the cold rolled thin strip steel can isolate between the inspector's body and the side of the cold rolled thin strip steel, and effectively protect the inspector's body to reduce safety hazards such as the inspector being cut by the cold rolled thin strip steel during the inspection process. And the inspection protective device further includes a positioning mechanism hinged to one end of the V-shaped body. At least two clamping members respectively hinged to both sides of the V-shaped body and capable of being clamped by snap-fit can clamp the cold rolled thin strip steel sleeved by the V-shaped body after the snap connection, making the position of the V-shaped body relative to the cold rolled thin strip steel relatively stable to effectively isolate the inspector from the cold rolled thin strip steel. The snap connection method can also facilitate the movement and separation of the V-shaped body relative to the cold rolled thin strip steel and will not affect the normal rolling and inspection process of the cold rolled thin strip steel.

Detailed implementation manners

[0028] In order to enable those skilled in the art in the technical field to which the present application belongs to more clearly understand the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0029] Please refer to FIG. Figure 1 Shows a schematic structural diagram of an inspection guard in one or more embodiments of the present application, Figure 2 Shows Figure 1 a top view of the inspection guard. In the first aspect embodiment of the present application, an inspection guard is provided, which is applied to the surface quality inspection of cold rolled thin strip steel 30, and includes a V-shaped body 1 and a positioning mechanism 2.

[0030] The V-shaped body 1 is used to sleeved on the cold rolled thin strip steel 30 to isolate the side surface of the cold rolled thin strip steel 30, and its thickness is greater than the thickness of the cold rolled thin strip steel 30.

[0031] The positioning mechanism 2 is hinged to one end of the V-shaped body 1. The positioning mechanism 2 includes at least two clamping members 21 respectively hinged to both sides of the V-shaped body 1. The at least two clamping members 21 are cooperated with a buckle 22, and the clamping members 21 cooperated with the buckle 22 are used to clamp the cold rolled thin strip steel 30.

[0032] When surface quality inspection is required for cold-rolled thin strip steel 30, the V-shaped body 1 can be sleeved on the cold-rolled thin strip steel 30 from the side of the cold-rolled thin strip steel 30, and one side of the V-shaped body 1 can be supported on the upper surface of the cold-rolled thin strip steel 30. When an inspector checks the upper surface of the cold-rolled thin strip steel 30 from the side of the cold-rolled thin strip steel 30, the V-shaped body 1 with a thickness greater than that of the cold-rolled thin strip steel 30 can isolate the inspector's body from the side of the cold-rolled thin strip steel 30 and effectively protect the inspector's body, so as to reduce potential safety hazards such as the inspector being cut by the cold-rolled thin strip steel 30 during the inspection process. The V-shaped body 1 has a relatively large thickness and thus higher strength, and can effectively withstand the acting force from the cold-rolled thin strip steel 30 during the inspection, effectively reducing the possibility of the staff being cut. The inspection protective device further includes a positioning mechanism 2 hinged to one end of the V-shaped body 1. At least two clamping members 21 respectively hinged to both sides of the V-shaped body 1 and capable of being cooperated through a buckle 22 in the positioning mechanism 2 can clamp the cold-rolled thin strip steel 30 sleeved by the V-shaped body 1 after the buckle 22 is connected, making the position of the V-shaped body 1 relative to the cold-rolled thin strip steel 30 relatively stable, so as to effectively isolate the inspector from the cold-rolled thin strip steel 30. The connection mode of the buckle 22 can also facilitate the movement and separation of the V-shaped body 1 relative to the cold-rolled thin strip steel 30 without affecting the normal rolling and inspection processes of the cold-rolled thin strip steel 30. To a certain extent, it solves the problem of potential safety hazards when inspecting the surface quality of thin strip steel.

[0033] In some embodiments, the included angle corresponding to the V-shaped body 1 is 20° to 60°. The protection effect can be ensured.

[0034] In some embodiments, the V-shaped body 1 is a steel V-shaped body 1, and its hardness is greater than that of the cold-rolled thin strip steel 30.

[0035] The steel V-shaped body 1 is easy to obtain, reducing the preparation cost of the V-shaped body 1. And the hardness of the steel V-shaped body 1 is greater than that of the cold-rolled thin strip steel 30, which can improve the isolation effect of the V-shaped body 1, so as to improve the overall safety of the inspection protective device and reduce potential safety hazards.

[0036] In certain embodiments, the material of the V-shaped body 1 can also be set as different steels or metals with higher hardness, and the hardness of the V-shaped body 1 can be higher than that of the cold-rolled thin strip steel 30. This is beneficial to improving the use safety of the inspection protective device.

[0037] In certain embodiments, the hardness of the V-shaped body 1 can also be the same as or slightly lower than that of the cold-rolled thin strip steel 30, and it can also play a protective role. This application does not limit this.

[0038] In some embodiments, the clamping member 21 is provided with an arc-shaped clamping surface 211 for contacting the cold-rolled thin strip steel 30. The clamping member 21 is provided with the arc-shaped clamping surface 211, which can position the cold-rolled thin strip steel 30 and the inspection protector while facilitating the separation of the inspection protector from the cold-rolled thin strip steel 30.

[0039] In certain embodiments, the clamping member 21 may also be provided with a clamping surface of different shapes for contacting the cold-rolled thin strip steel 30, and the clamping surface may be a flat surface or a curved surface. The present application does not limit this.

[0040] In certain embodiments, the clamping member 21 may be rod-shaped, block-shaped, plate-shaped or irregular in shape, and the clamping surface is one surface of the clamping member 21. The present application does not limit this.

[0041] In some embodiments, a positioning mechanism 2 is respectively hinged at both ends of the V-shaped body 1. Hinging a positioning mechanism 2 at both ends of the V-shaped body 1 respectively can facilitate the positioning and movement of the inspection protector body, and can also position the V-shaped body 1 on the cold-rolled thin strip steel 30 from different orientations, facilitating the operation of the inspection personnel.

[0042] In some embodiments, the inspection protector further includes a roller 3. The roller 3 is rotatably connected to the V-shaped body 1, and the axis extends along the width direction of the cold-rolled thin strip steel 30. It should be noted that Figure 2 the roller 3 is omitted.

[0043] If the roller 3 in the inspection protector is rotatably connected to the V-shaped body 1 and not connected by a buckle 22 between the clamping members 21, when it is necessary to move the V-shaped body 1, the V-shaped body 1 can be moved by rolling the roller 3 relative to the cold-rolled thin strip steel 30 to check different positions of the cold-rolled thin strip steel 30, facilitating the inspection of the surface quality of the cold-rolled thin strip steel 30.

[0044] In some embodiments, the V-shaped body 1 is provided with an installation groove 4, and the roller 3 is rotatably connected to the side wall of the installation groove 4.

[0045] The roller 3 is installed in the installation groove 4 of the V-shaped body 1, reducing the space required for the overall inspection protector and facilitating the overall movement of the inspection protector.

[0046] In certain embodiments, the roller 3 may also be rotatably connected to the side surface or the end of the V-shaped body 1, and may be provided as one or more. The present application does not limit this.

[0047] In some embodiments, the V-shaped body 1 is further provided with an observation groove 5 on the same side as the roller 3 and spaced from the roller 3. The roller 3 is supported on the cold-rolled thin strip steel 30, and the observation groove 5 on the same side of the V-shaped body 1 as the roller 3 can increase the observable area.

[0048] It should be noted that both sides of the V-shaped body 1 are located on both sides of the axis of the V-shaped body 1 respectively.
