Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure processing equipment, specifically a steel structure outer surface grinding equipment for production. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, which are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion and generally require rust removal, galvanizing, or painting, as well as regular maintenance.

[0003] I-beams are the most widely used steel in engineering. They can be assembled into various load-bearing components according to different structural needs, and can also be used as connecting parts between components. They are widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses.

[0004] I-beams typically require rust-proof painting to improve their rust resistance and extend their service life. Therefore, rust must be removed from the surface of the steel structure before painting to ensure that the rust-proof paint can be well absorbed by the I-beam surface. However, current rust removal methods mainly rely on manual hand-held grinders, which are not only inefficient and labor-intensive but also generate a lot of dust, endangering the health of operators. Utility Model Content

[0005] To address the problems of existing methods for grinding and removing rust from I-beams, which rely on manual grinding, are labor-intensive, inefficient, generate dust, and pose health risks, this utility model provides a steel structure outer surface grinding device for production.

[0006] This utility model is achieved through the following technical solution: A steel structure surface grinding device for production includes a housing. The upper side of the housing has an inverted T-shaped slot through which an I-beam can pass axially and horizontally. The top of the inner side of the housing has two symmetrical support rods about the slot. A first connecting plate is rotatably connected to the bottom of each support rod. A second connecting plate is rotatably connected to the inner side of each of the two first connecting plates. A first grinding wheel is rotatably connected between corresponding ends of the two first connecting plates, and a second grinding wheel is rotatably connected to the inner side of the other end of each of the two second connecting plates. A third grinding wheel is rotatably connected between corresponding ends of the two second connecting plates, and a fourth grinding wheel is rotatably connected to the inner side of the other end of each of the two second connecting plates. A motor 1 for driving the first grinding wheel and the two second grinding wheels is connected to the outer side of the first connecting plates. A motor 2 for driving the third grinding wheel and the two fourth grinding wheels is connected to the outer side of the second connecting plates. A spring is provided on the underside of the top plate of the housing to elastically press down on one side of the first and second connecting plates.

[0007] A further improvement of this utility model is that a mounting frame is provided on the upper side of the box, and a telescopic cylinder that extends downward is connected and installed on the mounting frame. Several guide posts are also provided on the upper side of the box, and a support frame that is slidably installed on the guide posts and connected to the telescopic end of the telescopic cylinder is provided. The lower side of the support frame is provided with a gap corresponding to the slot.

[0008] A further improvement of this utility model is that the bottom plate of the support frame is provided with several rollers on the inner side near the gap, which can provide rolling support for the underside of the top plate of the I-beam.

[0009] A further improvement of this utility model is that the box body is provided with brushes arranged along the side wall of the slot.

[0010] A further improvement of this utility model is that an opening is provided at the bottom of the side wall of the box, and a collection frame is slidably installed inside the opening.

[0011] A further improvement of this utility model is that a handle is provided on the outer wall of the collection frame.

[0012] A further improvement of this utility model is that a stop block is provided on the outer side of the second connecting plate.

[0013] As can be seen from the above technical solutions, the beneficial effects of this utility model are: In use, the I-beam is horizontally inserted into one side of the slot. Motors one and two are started, driving the grinding wheel to rotate and pushing the I-beam inward. This brings the upper and lower surfaces of the I-beam's base plate into contact with the high-speed rotating grinding wheel. Due to the downward elastic pressure of the springs on the upper sides of the first and second connecting plates, the plates rotate around the lower side of the support rod, causing the grinding wheel to clamp tightly against the upper and lower surfaces of the I-beam's base plate for rust removal. The two sets of rust-removing grinding wheels housed within the housing effectively clean the upper and lower surfaces of the I-beam's base plate, improving work efficiency. This eliminates the need for manual grinding, avoids the harmful effects of rust dust, and reduces labor intensity. Attached Figure Description

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] like Figure 1-6As shown, a steel structure outer surface grinding equipment for production includes a housing 1. The upper side of the housing 1 is provided with an inverted T-shaped slot 2 that allows an I-beam to pass horizontally through it axially. The top inner side of the housing 1 is provided with two support rods symmetrical about the slot 2. The bottom of the two support rods 3 are respectively rotatably connected to a first connecting plate 4. The inner sides of the two first connecting plates 4 are respectively rotatably connected to a second connecting plate 5. A first grinding wheel 6 is rotatably connected between corresponding ends of the two first connecting plates 4, and a second grinding wheel 7 is respectively connected to the inner side of the other end. A third grinding wheel 8 is rotatably connected between corresponding ends of the two second connecting plates 5, and a fourth grinding wheel 9 is respectively connected to the inner side of the other end. A motor 10 for driving the first grinding wheel 6 and the two second grinding wheels 7 is connected to the outer side of the first connecting plate 4. A motor 2 11 for driving the third grinding wheel 8 and the two fourth grinding wheels 9 is connected to the outer side of the second connecting plate 5. A spring 12 is provided on the lower side of the top plate of the housing 1 to elastically press down on one side of the first connecting plate 4 and the second connecting plate 5.

[0024] In use, the I-beam is horizontally inserted into the slot 2 on one side. Two motors (10) and four motors (11) are activated, driving the corresponding grinding wheels to rotate. The I-beam is pushed horizontally inward at a uniform speed, bringing the upper and lower surfaces of the I-beam's base plate into contact with the high-speed rotating grinding wheels. Due to the downward elastic pressure of the spring 12 on the upper sides of the first connecting plate 4 and the second connecting plate 5, the spring rotates around the lower side of the support rod 3, causing each grinding wheel to clamp tightly against the upper and lower surfaces of the I-beam's base plate for rust removal. The two sets of rust-removing grinding wheels inside the housing 1 can clean the upper and lower surfaces of the I-beam's base plate, improving work efficiency. This eliminates the need for manual grinding, avoiding the harm caused by rust dust and reducing labor intensity. The other side of the I-beam is also pushed into the device, allowing rust removal on the upper and lower surfaces of the I-beam's plates. Unrusted areas are cleaned using other tools or with manual assistance.

[0025] It should be noted that the vertical center of the horizontal part of the slot 2 on both sides of the box body 1 needs to be at the same horizontal position as the rotation center of the first connecting plate 4 and the second connecting plate 5, and ensure that the part of the I-beam to be ground that extends into the box body 1 is also at the same horizontal position, so that the grinding wheels on the upper and lower sides of the I-beam can grind and remove rust with the same pressure.

[0026] The upper side of the housing 1 is equipped with a mounting bracket 13, on which a telescopic cylinder 15 is connected and installed. Several guide posts 14 are also provided on the upper side of the housing 1. A support frame 16, connected to the telescopic end of the telescopic cylinder 15, is slidably mounted on the guide posts 14. The lower side of the support frame 16 has a gap 17 corresponding to the slot 2. By setting the telescopic cylinder 15 to drive the support frame 16 to move up and down along the guide posts 14, when the I-beam is inserted into the device, the upper side of the I-beam engages with the gap 17. The inner side of the bottom plate of the support frame 16 supports the lower surface of the upper plate of the I-beam. This allows I-beams of different specifications and models to be ground and rust-removed by a grinding wheel, improving the adaptability to rust removal of different types of I-beams.

[0027] It should be noted that the telescopic cylinder 15 can be controlled by servo hydraulics. On the one hand, it can ensure sufficient support force to support the H-beam. On the other hand, the servo hydraulics can achieve automatic lifting and lowering by working with the controller to handle the rust removal work of H-beams of different specifications and models.

[0028] The support frame 16 has several evenly arranged rollers 18 on its inner side near the gap 17, which provide rolling support for the underside of the top plate of the I-beam. The rollers 18 support the lower surface of the top plate of the I-beam and, when the I-beam is pushed into the device, change sliding friction to rolling friction, reducing the resistance to pushing in and improving work efficiency.

[0029] The housing 1 is equipped with brushes 19 arranged along the side wall of the slot 2. The brushes 19 can prevent rust removal dust from escaping from the gap between the slot 2 and the I-beam, further reducing dust pollution to the environment. At the same time, after the I-beam is rusted, the brushes 19 can brush off most of the dust remaining on the I-beam and leave it inside the housing 1, reducing dust spillage and environmental pollution.

[0030] The box 1 has an opening 20 at the bottom of its side wall, and a collection frame 21 is slidably installed inside the opening 20. After the rust removal operation on the I-beam is stopped, the box 21 can collect the dust after a period of time, and then the rust inside the collection frame 21 can be cleaned.

[0031] The collection frame 21 is equipped with a handle 22 on its outer wall. The handle 22 allows the collection frame 21 to be easily pulled out, so as to clean the rust inside the collection frame 21 in a timely manner.

[0032] The second connecting plate 5 has a stop block 23 on its outer side. The stop block 23 can block the first connecting plate 4 to prevent the grinding wheels on the same side from contacting each other, that is, to prevent the first grinding wheel 6 from contacting the fourth grinding wheel 9, and to prevent the second grinding wheel 7 and the third grinding wheel 8 from contacting each other, which would easily cause wear between the grinding wheels.

[0033] Both motor 10 and motor 21 are dustproof motors, requiring regular cleaning. They are electrically connected to the controller, which can be a common PLC controller, such as the Siemens S7-200+ series. During use, start two motors (10) and four motors (11) separately to prevent simultaneous starting, which could cause excessive current and damage to the circuit. Each motor drives its corresponding grinding wheel to rotate, allowing the I-beam to be horizontally inserted from slot 2 on one side. The support frame 16 provides support for the upper plate of the I-beam, allowing the lower plate to suspend as it enters between the grinding wheels. Then, it is placed horizontally at a uniform speed. Pushing the I-beam base plate into housing 1 allows its upper and lower surfaces to come into contact with the high-speed rotating grinding wheels for rust removal. Due to the downward elastic pressure of spring 12 on the upper sides of the first connecting plate 4 and the second connecting plate 5, the spring rotates around the lower side of the support rod 3, causing each grinding wheel to clamp tightly against the upper and lower surfaces of the I-beam base plate for rust removal. When cleaning and removing rust from I-beams of different specifications, simply select the corresponding program via the controller and adjust the support frame 16 up and down using the telescopic cylinder 15 to ensure that different I-beams can be cleaned and rust-removed. The two sets of rust-removing grinding wheels inside housing 1 clean and remove rust from the upper and lower surfaces of the I-beam base plate, improving work efficiency. This eliminates the need for manual grinding, avoids the harm caused by rust dust, and reduces labor intensity. Pushing the other side of the I-beam into the device similarly removes rust from the upper and lower surfaces of the I-beam plates. Unrusted areas are cleaned using other tools or with manual assistance.

[0034] It should be noted that ventilation openings are provided on both sides of the box 1, and the ventilation openings are connected to pipes. The pipes are connected to an exhaust gas treatment station with active suction to circulate outside air into the box 1, ensuring that the temperature inside the box 1 is maintained at the normal operating temperature. Due to the weak suction, the rust-removed iron slag will still fall into the collection box 21, reducing the harm to the staff caused by dust escaping.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
