Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling production, in particular to a slab cleaning device. Background Art

[0002] Part of the slabs used in the heating furnace of the hot rolling production line are low-temperature slabs and cold slabs. There will be iron oxide fragments, debris and dirt on the surface of low-temperature slabs and cold slabs. Manual cleaning is generally used to remove the iron oxide fragments, debris and dirt. However, due to the high temperature of the slabs before loading into the furnace, manual cleaning of the slabs is prone to cause safety risks, and the efficiency of manual cleaning is low.

[0003] The utility model with patent number CN214771176U discloses an automatic billet sweeping device for a heating furnace. By installing the automatic billet sweeping device on the roller table, automatic cleaning can be achieved by utilizing the roller table conveying function, thereby improving online operation efficiency, reducing labor intensity, and eliminating safety hazards. However, it is not capable of cleaning only the billets to be cleaned, and the height of the steel brush still needs to be adjusted manually. Utility Model Content

[0004] The purpose of the utility model is to provide a slab cleaning device to solve at least one aspect of the problems and defects raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A slab cleaning device comprises a roller conveyor and a slab on the roller conveyor, and further comprises:

[0007] A first brush roller and a second brush roller, wherein the first brush roller and the second brush roller are arranged on the upper part of the slab;

[0008] The first brush roller and the second brush roller are respectively provided with a first motor and a second motor at one end away from the slab;

[0009] The first brush roller is connected to the second brush roller via a connecting shaft at one end close to the slab;

[0010] A lifting device is arranged on the upper part of the first brush roller and the second brush roller, and two ends of the lifting device are respectively connected to the first motor and the second motor through connecting plates.

[0011] The slab cleaning device according to this solution has at least the following technical effects:

[0012] The slab cleaning device is provided with a lifting device on the upper part of the first brush roller and the second brush roller, and the two ends of the lifting device are respectively connected to the first motor and the second motor through a connecting plate, so as to drive the first brush roller and the second brush roller to rise and fall. When the slab that does not need to be cleaned passes through the roller conveyor, the lifting device drives the first brush roller and the second brush roller to rise, so as to avoid the brush rollers from contacting the upper surface of the slab; when the slab that needs to be cleaned passes through the roller conveyor, the lifting device drives the first brush roller and the second brush roller to descend, so that the brush rollers contact the upper surface of the slab and clean the upper surface of the slab, thereby realizing a higher degree of automation in removing the iron oxide fragments, debris and dirt on the upper surface of the slab. The slab cleaning device has a simple structure, performs cleaning work on the slab to be cleaned, and does not need to manually adjust the height of the brush roller, which further improves the work efficiency.

[0013] As a further solution of the utility model: the lifting device includes a lifting beam and a lifting rod.

[0014] Since the lifting device includes a lifting beam and a lifting rod, the height of the cleaning device is controlled by the lifting beam and the lifting rod, so that the contact pressure between the first brush roller, the second brush roller and the slab can be adjusted, which can adapt to slabs of different sizes and thicknesses and ensure that the brush roller is in close contact with the upper surface of the slab to be cleaned.

[0015] As a further solution of the present invention: the first brush roller and the second brush roller are independently selected from spiral iron brush rollers.

[0016] Since the first brush roller and the second brush roller are independently selected as spiral iron brush rollers, the spiral iron brush rollers can push the cleaned iron oxide fragments, debris and dirt from the edge of the slab into the slag cleaning groove at the bottom of the roller in time to avoid slag accumulation on the upper surface of the slab and causing slag jamming in the brush roller.

[0017] As a further solution of the present invention: the first brush roller and the second brush roller are arranged in an "eight-shaped" shape.

[0018] Because the first brush roller and the second brush roller are arranged in an "eight-shaped" shape, the cleaning coverage area is larger, the contact area between the first brush roller, the second brush roller and the slab is increased, the cleaning time is saved, the cleaning efficiency is improved, and the service life of the brush roller is increased.

[0019] As a further solution of the utility model: shield plates are respectively provided on the upper parts of the first brush roller and the second brush roller.

[0020] Since the upper parts of the first brush roller and the second brush roller are respectively provided with shield plates, the iron oxide fragments, debris and dirt are prevented from splashing during the cleaning process, thereby avoiding environmental pollution.

[0021] As a further solution of the utility model: support plates are respectively provided on one side of the shield plates on both sides, and the support plates on both sides are respectively connected to the first brush roller and the second brush roller.

[0022] Since support plates are respectively provided on one side of the two side guard plates, and the two side support plates are respectively connected to the first brush roller and the second brush roller, the support plates can provide stable support for the cleaning device, so that the brush roller remains stable during rotation, avoiding shaking, deviation or abnormal vibration due to uneven force on the brush roller during cleaning, thereby ensuring the normal progress of the cleaning operation.

[0035] like Figure 1-3 The embodiment of the utility model shown is a slab cleaning device, including a roller 101 and a slab 102 on the roller 101, and also including: a first brush roller 103 and a second brush roller 104, the first brush roller 103 and the second brush roller 104 are arranged on the upper part of the slab 102; the first brush roller 103 and the second brush roller 104 are respectively provided with a first motor 105 and a second motor 106 at one end away from the slab 102; the first brush roller 103 and the second brush roller 104 are connected at one end close to the slab 102 by a connecting shaft 107; a lifting device 108, the lifting device 108 is arranged on the upper part of the first brush roller 103 and the second brush roller 104, and the two ends of the lifting device 108 are respectively connected to the first motor 105 and the second motor 106 by connecting plates 109.

[0036] Specifically, the slab cleaning device is provided with a lifting device 108 on the upper part of the first brush roller 103 and the second brush roller 104, and the two ends of the lifting device 108 are respectively connected to the first motor 105 and the second motor 106 through the connecting plate 109, so as to drive the first brush roller 103 and the second brush roller 104 to rise and fall. When the slab 102 that does not need to be cleaned passes through the roller conveyor 101, the lifting device 108 drives the first brush roller 103 and the second brush roller 104 to rise, so as to avoid the contact between the brush rollers and the upper surface of the slab 102; when the slab 102 that needs to be cleaned passes through the roller conveyor 101, the lifting device 108 drives the first brush roller 103 and the second brush roller 104 to descend, so that the brush rollers contact with the upper surface of the slab 102, and clean the upper surface of the slab 102, thereby realizing a higher degree of automation in removing the iron oxide fragments, debris and dirt on the upper surface of the slab 102. The slab cleaning device has a simple structure and performs cleaning work on the slab 102 to be cleaned without manually adjusting the height of the brush roller, thereby further improving work efficiency.

[0037] like Figure 2 As shown, the lifting device 108 includes a lifting beam 1081 and a lifting rod.

[0038] Specifically, since the lifting device 108 includes a lifting beam 1081 and a lifting rod, the height of the cleaning device is controlled by the lifting beam 1081 and the lifting rod, so that the contact pressure between the first brush roller 103, the second brush roller 104 and the slab 102 can be adjusted, which can adapt to slabs 102 of different sizes and thicknesses, ensuring that the brush roller is in close contact with the upper surface of the slab 102 to be cleaned.

[0039] According to an embodiment of the present invention, the first brush roller 103 and the second brush roller 104 are independently selected from spiral iron brush rollers.

[0040] Specifically, since the first brush roller 103 and the second brush roller 104 are independently selected as spiral iron brush rollers, the spiral iron brush rollers can promptly push the cleaned iron oxide fragments, debris and dirt from the edge of the slab 102 into the slag cleaning groove at the bottom of the roller 101 to avoid accumulation on the upper surface of the slab 102 and causing slag jamming in the brush rollers.

[0041] like Figure 1 As shown, the first brush roller 103 and the second brush roller 104 are arranged in an "eight-shaped" shape.

[0042] Specifically, since the first brush roller and the second brush roller are arranged in an "eight-shaped" shape, the cleaning coverage area is larger, the contact area between the first brush roller, the second brush roller and the slab is increased, cleaning time is saved, cleaning efficiency is improved, and the service life of the brush roller is increased.

[0043] like Figure 3 As shown, shield plates 110 are respectively disposed on the upper portions of the first brush roller 103 and the second brush roller 104 .

[0044] Specifically, since the upper parts of the first brush roller 103 and the second brush roller 104 are respectively provided with shield plates 110, during the cleaning process, it is possible to prevent the iron oxide fragments, debris and dirt from splashing, thereby avoiding environmental pollution.

[0045] like Figure 3 As shown, support plates 111 are respectively provided on one side of the two side shield plates 110 , and the two side support plates 111 are respectively connected to the first brush roller 103 and the second brush roller 104 .

[0046] Specifically, since support plates 111 are respectively provided on one side of the two side shield plates 110, and the two side support plates 111 are respectively connected to the first brush roller 103 and the second brush roller 104, the support plates 111 can provide stable support for the cleaning device, so that the brush roller remains stable during rotation, avoiding shaking, deviation or abnormal vibration due to uneven force on the brush roller during cleaning, thereby ensuring the normal progress of the cleaning operation.
