Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction devices, and in particular to a surface cleaning device and method for an I-beam arch. Background Art

[0002] During the production process of I-beam arches, oil or other stains may be generated. At the same time, if the steel arches cannot be installed in time after processing, they need to be temporarily stored. Rust may be generated during the storage process. Therefore, it is necessary to clean the surface of the I-beam workpiece before installing the arches, so that it can be better bonded with the concrete.

[0003] In the prior art, sandblasting or grinding wheel grinding is generally used. The devices used are conventional sandblasting machines and grinding machines. However, these devices are general tools and cannot better meet the surface cleaning scenarios of I-beam arch frames. Summary of the invention

[0004] The object of the present invention is to provide a surface cleaning device and method for an I-beam arch frame, which can conveniently clean dirt on the surface of the I-beam arch frame.

[0005] The embodiments of the present invention are implemented by the following technical solutions:

[0006] A surface cleaning device for an I-beam arch comprises a shell and a plurality of spray guns; openings are arranged on opposite sides of the shell so that the arch can enter and exit the shell through the openings; the plurality of spray guns are arranged in a ring shape inside the shell and a channel surrounded by the plurality of spray guns faces the openings; a funnel-shaped discharge hopper is arranged at the bottom of the shell; and the plurality of spray guns are connected to a sandblasting machine.

[0007] Furthermore, two partitions are provided inside the shell; a plurality of the spray guns are provided between the two partitions; and the two partitions are also provided with openings corresponding to the arches, so that the arches can pass through the openings of the partitions and through the channel surrounded by the plurality of the spray guns.

[0008] Furthermore, the sizes of the plurality of openings are larger than the size of the arch frame; the opening of the shell is provided with bristles so that the bristles close the gap between the opening and the arch frame.

[0009] Furthermore, a scraper is provided at the opening of the partition; the scraper closes the gap between the opening and the arch frame; and the scraper is made of silicone.

[0010] Furthermore, it also includes a plurality of conveying rollers; the plurality of conveying rollers are arranged in conjunction with the shell so that the arch frame can enter and exit the shell under the drive of the conveying rollers.

[0011] Furthermore, the arch frame includes a connecting portion and a group of flange plates connected to both sides of the connecting portion, so that the cross-section of the arch frame is I-shaped; the flange plates are perpendicular to the connecting portion; and a plurality of conveying rollers are arranged at an angle so that when the arch frame is placed on the conveying rollers, the flange plates are inclined to the horizontal plane.

[0012] Furthermore, it also includes a cleaning roller; along the direction of movement of the arch, the cleaning roller is arranged behind the spray gun; the cleaning roller is attached to the arch and is located in the groove portion where the arch sinks.

[0013] Furthermore, a guide ring is arranged inside the shell; and a plurality of the spray guns are connected to the guide ring via a gooseneck rod.

[0014] Furthermore, it also includes a sand material recovery device; the sand material recovery device is connected to the discharge hopper.

[0015] A surface cleaning method for an I-beam arch frame adopts the surface cleaning device for the I-beam arch frame. The cleaning method comprises: placing the arch frame on a conveying roller and conveying it into an outer shell; and turning on a sandblasting machine so that a plurality of spray guns sandblast the surface of the arch frame.

[0016] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects:

[0017] When the surface cleaning device for an I-beam arch frame of the present invention is used, the arch frame to be processed is sent in through the opening on one side of the shell and sent out from the opening on the other side of the shell after passing through a passage surrounded by a plurality of spray guns. When the arch frame passes through the inside of the shell, the sandblasting machine sprays sand onto the surface of the arch frame through the spray gun, thereby removing dirt and rust on the surface of the arch frame.

[0018] Since the spray guns are arranged in a ring, the arch frame can be sandblasted all around, and the arch frame can be treated completely without dead angles. The sandblasting is carried out inside the shell, so that the sprayed sand material and the generated powder are collected in the discharge hopper at the bottom of the shell and discharged through the discharge hopper, so as to avoid the sand material and powder after sandblasting being scattered on the ground. At the same time, the collected sand material can be reused after processing.

[0019] The spray gun is set between two partitions so that the sprayed sand material is blocked by the partitions on both sides and then falls into the discharge hopper through the gap between the two partitions. The air sprayed from the spray gun will bypass the partition and be discharged through the opening of the shell. The blocking of the partition prevents the sand material from being directly sprayed near the opening of the shell and flowing out with the air flow. This can better prevent the sand material and powder after sandblasting from scattering on the ground. The opening of the partition is provided with a scraper to scrape off the sand material remaining on the flange plate of the arch frame. The opening of the shell is provided with bristles to wash the impurities attached to the surface of the arch frame again, and can also discharge the internal gas through the gap between the bristles while closing the gap between the arch frame and the opening.

[0020] The conveying roller makes the arch flange plate tilted to the horizontal plane, so that only the groove part of the arch can store sand materials, and the sand materials in other parts slide into the discharge hopper. The amount of sand materials retained on the arch is reduced, and the workload of removing the retained sand materials is also reduced. At the same time, a cleaning roller is set at the groove to clean the only part where sand materials are retained. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1-Figure 4 As shown, the present invention provides a surface cleaning device for an I-beam arch frame 1, comprising a housing 2 and a plurality of spray guns 3. The housing 2 is provided with openings on opposite sides, so that the arch frame 1 enters the housing 2 through one opening and then flows out of the housing 2 through the other opening. The plurality of spray guns 3 are arranged in a ring shape inside the housing 2, and the passage surrounded by the plurality of spray guns 3 faces the openings. Figure 2 and Figure 4 As shown. A funnel-shaped discharge hopper 4 is provided at the bottom of the housing 2. Several spray guns 3 are connected to a sandblasting machine. The sandblasting machine can provide high-pressure gas and sand materials to the spray guns 3. The high-pressure gas is quickly sprayed out through the spray guns 3, carrying the sand materials to quickly impact the surface of the arch frame 1, thereby removing impurities on the surface of the arch frame 1.

[0027] When the surface cleaning device of the I-beam arch frame 1 of the present invention is used, the arch frame 1 to be processed is sent in through the opening on one side of the shell 2 and sent out from the opening on the other side of the shell 2 after passing through the channel surrounded by a plurality of spray guns 3. When the arch frame 1 passes through the inside of the shell 2, the sandblasting machine sprays sand on the surface of the arch frame 1 through the spray gun 3, thereby removing dirt and rust on the surface of the arch frame 1.

[0028] Since the spray guns 3 are arranged in a ring shape, the arch frame 1 can be sandblasted all around, thereby performing a comprehensive treatment on the arch frame 1 without dead angles. The sandblasting is performed inside the housing 2, so that the sprayed sand material and the generated powder are collected in the discharge hopper 4 at the bottom of the housing 2 and discharged through the discharge hopper 4, so as to avoid the sand material and powder after sandblasting being scattered on the ground. At the same time, the collected sand material can be reused after processing. The sand material can be corundum, glass sand, ceramic sand, quartz sand, etc.

[0029] In this embodiment, two partitions 5 are further provided inside the housing 2. Figure 1 As shown, a plurality of spray guns 3 are arranged between two partitions 5. The two partitions 5 are also provided with openings corresponding to the arch 1, so that the arch 1 passes through the openings of the partitions 5 and through the passages surrounded by the plurality of spray guns 3.

[0030] The spray gun 3 is arranged between two partitions 5, so that the splashed sand material is blocked by the partitions 5 on both sides, and then falls into the discharge hopper 4 through the gap between the two partitions 5. The air sprayed from the spray gun 3 bypasses the partitions 5 and is discharged through the opening of the housing 2. The blocking of the partitions 5 prevents the sand material from being directly sprayed toward the vicinity of the opening of the housing 2 and flowing out with the air flow. This better prevents the sand material and powder after sandblasting from being scattered on the ground.

[0031] In this embodiment, the sizes of the plurality of openings are larger than the size of the arch frame 1. The opening of the housing 2 is provided with bristles 6 so that the bristles 6 close the gap between the opening and the arch frame 1. The opening size is larger than the arch frame 1 so that the arch frame 1 can easily enter the interior of the housing 2. The bristles 6 are provided at the opening so that the arch frame 1 can push aside the bristles 6 and pass through. At the same time, the bristles 6 can also close the gap between the opening and the arch frame 1.

[0032] In this embodiment, the opening of the partition 5 is provided with a scraper 7. The scraper 7 closes the gap between the opening and the arch 1. The scraper 7 is made of silicone. The scraper 7 made of silicone can also pass through the arch 1. At the same time, the scraper 7 is an integral type and will not be scattered relative to the bristles 6. The sand material accumulated on the flange plate 10 of the arch 1 is scraped off by the scraper 7. Figure 2 As shown, the scraper 7 can be composed of four pieces. Each scraper 7 is arranged to match the shape of the arch frame 1 so that it just fits the surface of the arch frame 1. This better prevents the sand material from flowing out through the opening of the shell 2.

[0033] The opening of the partition 5 is provided with a scraper 7 to scrape off the sand material remaining on the flange plate 10 of the arch frame 1. The opening of the shell 2 is provided with a brush 6 to clean the impurities attached to the surface of the arch frame 1 again, and the internal gas can be discharged through the gap between the brushes 6 while closing the gap between the arch frame 1 and the opening.

[0034] In this embodiment, a plurality of conveying rollers 8 are also included. Figure 1As shown, a plurality of conveying rollers 8 are arranged in cooperation with the outer shell 2 so that the arch 1 can move in and out of the outer shell 2 under the drive of the conveying rollers 8 .

[0035] In this embodiment, the arch frame 1 includes a connecting portion 9 and a group of flange plates 10 connected to both sides of the connecting portion 9, so that the cross section of the arch frame 1 is an I-shaped. The flange plates 10 are perpendicular to the connecting portion 9. The cross section of the arch frame 1 is as follows: Figure 2 and Figure 4 Generally, the arch 1 is placed flat on the conveying roller 8. Figure 2 As shown, the flange plate 10 is horizontal. This way, sand material may be retained on both sides of the lower flange plate 10. Both sides of the arch frame 1 need to be cleaned to prevent the sand material from flowing out.

[0036] The conveying roller 8 can also be arranged in another way, such as Figure 4 As shown, a plurality of conveying rollers 8 are arranged obliquely so that when the arch frame 1 is placed on the conveying rollers 8, the flange plate 10 is inclined to the horizontal plane. This makes it possible for only the groove 12 of the arch frame 1 to store sand material.

[0037] In this embodiment, a cleaning roller 11 is also included. Figure 3 As shown, along the direction of movement of the arch frame 1, the cleaning roller 11 is arranged behind the spray gun 3. Figure 4 As shown, the cleaning roller 11 is fitted to the arch frame 1 and is located at the groove 12 where the arch frame 1 sinks. When the cleaning roller 11 rotates, the sand material stored in the groove 12 can be swept away.

[0038] In this embodiment, a guide ring 13 is provided inside the housing 2. A plurality of spray guns 3 are connected to the guide ring 13 through a gooseneck rod. The airflow is dispersed to each spray gun 3 through the guide ring 13, and then the sand material is sprayed at high speed onto the surface of the arch frame 1. The gooseneck rod is a common component, which is often used in scenes such as microphone stands. It can be bent arbitrarily and support the component to be supported in the required position. There will also be different types of gooseneck rods as needed, and the force required for bending is different. The connection through the gooseneck rod makes it possible to adjust the angle of the spray gun 3, so as to better perform sandblasting on complex parts such as the corners of the arch frame 1.

[0039] In this embodiment, a sand material recovery device is also included. The sand material recovery device is connected to the discharge hopper 4. Thus, the collected sand materials can be screened and processed, and then reused.

[0040] The present invention also provides a surface cleaning method of an I-beam arch frame 1, using the above-mentioned surface cleaning device of the I-beam arch frame 1. The cleaning method is: placing the arch frame 1 on a conveying roller 8 and conveying it into the housing 2. Turning on a sandblasting machine so that a plurality of spray guns 3 sandblast the surface of the arch frame 1.
