Description

Technical Field

[0001] The present invention relates to the technical field of steel bar processing in construction engineering, and particularly to an anti-rust device for embedded and exposed steel bars in construction engineering. Background Art

[0002] In the casting of reinforced concrete structures in construction engineering, steel bars are often embedded in the reinforced concrete structures to ensure the integrity of the concrete structure. However, these embedded steel bars quickly rust in the air, and with the passage of time, corrosion will occur. After the steel bars are corroded, problems such as poor welding will occur. Therefore, it is necessary to use an anti-rust device for embedded and exposed steel bars in construction engineering to prevent the steel bars from rusting.

[0003] In traditional technologies, the anti-rust treatment for exposed steel bars is divided into two categories. One is to install a protective cover on the outside of the exposed steel bar to achieve anti-rust by isolating the steel bar from the outside. Although this method can achieve the anti-rust effect, it needs to be removed twice during the subsequent concrete pouring, which is time-consuming and laborious and affects the construction progress. The other method is to spray an isolation paint layer on the outside of the exposed steel bar to isolate the steel bar from the outside to achieve anti-rust. This method does not require later removal and is more time-saving and labor-saving. However, in existing anti-rust devices, most only roughly clean the surface of the exposed steel bar before spraying paint, which will cause the rust layer and stubborn impurities on the surface of the exposed steel bar not to be effectively cleaned, resulting in poor adhesion between the isolation paint layer and the steel bar surface, and the paint layer will fall off before the pouring period, and problems such as secondary paint replenishment are required. Summary of the Invention

[0036] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0037] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0038] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0039] Embodiment 1

[0040] Referring to Figures 1 to 3 , this is the first embodiment of the present invention. This embodiment provides an anti-rust device for embedded and exposed steel bars in construction engineering, which can perform all-round grinding and polishing on embedded and exposed steel bars of different sizes and spray a paint layer for rust prevention. It includes an adjustment unit 100, which includes a support assembly 101, a rotation assembly 102 arranged inside the support assembly 101, and a connection assembly 103 arranged inside the rotation assembly 102.

[0041] Furthermore, an anti-rust unit 200 includes a polishing assembly 201 arranged on the left inner wall of the connection assembly 103, a dust cleaning assembly 202 arranged on the right inner wall of the connection assembly 103, and a spraying assembly 203 arranged inside the connection assembly 103 and below the polishing assembly 201.

[0042] Further, the support component 101 is used to support and adjust the vertical height of the rotating component 102 as a whole; the rotating component 102 is used to control the anti-rust unit 200 to rotate along the exposed surface of the embedded steel bar; the polishing component 201 is used to polish and remove impurities on the surface of the exposed steel bar; the dust cleaning component 202 is used to clean the impurities attached to the steel bar after polishing; the spraying component 203 is used to spray an anti-rust paint layer on the polished steel bar.

[0043] It should be noted that the circuit control involved in the present invention is all controlled by a single-chip microcomputer after programming, and the required programs and the like are all prior arts. Therefore, the rest of this application will not be described in detail. The support component 101, the rotating component 102, the polishing component 201, the dust cleaning component 202, and the spraying component 203 are all powered by an internal battery or an external power supply. The spraying component 203 is connected to an external paint supply pipe, and the paint liquid is pumped into the spraying component 203 by an external pump for spraying operation.

[0044] During use, the anti-rust unit 200 and the like are sleeved outside the embedded exposed steel bar through the support component 101 and supported as a whole. The polishing component 201 and the dust cleaning component 202 are started in sequence. The polishing component 201 contacts the surface of the steel bar for polishing to remove the rust layer and impurities formed on the surface of the steel bar. The rotating component 102 is started to drive the entire anti-rust unit 200 to rotate in a circle along the steel bar, so that the polishing component 201 can perform all-round polishing on the periphery of the steel bar. At the same time, the dust cleaning component 202 can output air flow, and use the air flow to blow away the dust generated by polishing from the surface of the steel bar during the rotation process. During the circular rotation, the support component 101 can be started according to the exposed length of the embedded steel bar, so that it can pull the rotating component 102 to perform vertical lifting movement, and then drive the polishing component 201 and the like to polish steel bars of different lengths. After polishing and dust cleaning the surface of the steel bar, the spraying component 203 is started immediately. Relying on the pressure of the external pump, the anti-rust paint liquid is pumped and sprayed onto the surface of the polished steel bar under the action of the spraying component 203, so as to achieve the anti-rust treatment of the steel bar.

[0045] In summary, through the adjustment unit 100, the treatment position of the anti-rust unit 200 on the embedded exposed steel bar can be changed to effectively perform anti-rust treatment on embedded steel bars of different sizes and different exposed lengths. At the same time, in cooperation with the adjustment unit 100, the anti-rust unit 200 efficiently polishes and removes the impurities that affect the adhesion of the anti-rust paint layer on the exposed surface of the embedded steel bar, laying a good foundation for the spraying of the anti-rust paint layer, so that the paint layer can be evenly and tightly sprayed, with a longer action time, and can more effectively isolate the exposed steel bar from the external environment, thereby realizing the anti-rust treatment of the exposed steel bar.

[0046] Embodiment 2

[0047] Refer toFigures 1 to 11 , which is the second embodiment of the present invention. The difference from the first embodiment is that it further includes. In the previous embodiment, the anti-rust device for embedded and exposed steel bars in construction engineering includes a support assembly 101, which includes two groups of support frames 101a, cavities 101b respectively opened inside the two groups of support frames 101a, and lifting members 101c respectively arranged at the tops of the two groups of support frames 101a.

[0048] Furthermore, the lifting member 101c includes connection boxes 101c-1 respectively arranged at the tops of the two groups of support frames 101a, grips 101c-2 respectively arranged outside the two groups of connection boxes 101c-1, and a first motor 101c-3 arranged inside the left connection box 101c-1. The output end of the first motor 101c-3 is fixedly provided with a connection shaft 101c-4. A winding roller 101c-5 is fixedly arranged on the outside of the connection shaft 101c-4. A traction rope 101c-6 that penetrates into the cavity 101b and is connected to the rotating assembly 102 is wound around the outside of the winding roller 101c-5, so as to drive the rotating assembly 102 to perform vertical lifting movement.

[0049] It should be noted that the first motor 101c-3 is powered by an external power supply and controlled by a built-in switch, and the switch is a programmable device such as a single-chip microcomputer.

[0050] Further, the rotating assembly 102 includes sliders 102a respectively slidably arranged inside the two groups of cavities 101b, a fixed ring 102b arranged on the side where the two groups of sliders 102a are close to each other, an adjustment cavity 102c opened inside the fixed ring 102b, and an engaging member 102d arranged on the inner peripheral wall of the fixed ring 102b.

[0051] Furthermore, the engaging member 102d includes a rotating opening 102d-1 opened on the inner peripheral wall of the fixed ring 102b, a rotating ring 102d-2 rotatably arranged inside the rotating opening 102d-1, and an external tooth ring 102d-3 fixedly arranged on the outside of the rotating ring 102d-2 and located inside the adjustment cavity 102c. The upper surface of the fixed ring 102b is fixedly provided with a second motor 102d-4, and the output end of the second motor 102d-4 is provided with a driving shaft 102d-5 that penetrates into the adjustment cavity 102c, and a gear 102d-6 fixedly arranged on the outside of the driving shaft 102d-5 and meshed with the external tooth ring 102d-3, so as to drive the rotating ring 102d-2 to rotate under the drive of the second motor 102d-4.

[0052] It should be noted that the second motor 102d-4 is the same as the first motor 101c-3, and both are powered by an external power supply and controlled by a built-in switch.

[0053] Further, the polishing assembly 201 includes a first fixing piece 201a disposed on the left inner wall of the connecting sleeve 103b, four groups of springs 201b disposed on the side of the first fixing piece 201a away from the connecting sleeve 103b, and a push plate 201c disposed at one end of the four groups of springs 201b away from the first fixing piece 201a.

[0054] It should be noted that the four groups of springs 201b are respectively disposed at the four corners of the push plate 201c to provide an elastic movement margin for the push plate 201c, so as to push the polishing head 201f to contact the surface of the exposed steel bar, cope with steel bars of different sizes, and at the same time be able to apply a thrust force during grinding and polishing to make the grinding more meticulous.

[0055] Furthermore, the polishing assembly 201 further includes two groups of rotating holes 201d opened on the outer side of the push plate 201c, rotating shafts 201e respectively rotatably disposed inside the two groups of rotating holes 201d, and polishing heads 201f respectively fixedly disposed at the right ends of the two groups of rotating shafts 201e. Belt pulleys 201g are disposed on the outer sides of the two groups of rotating shafts 201e, and a belt 201h for driving the two groups of belt pulleys 201g to move synchronously is disposed on the outer sides of the two groups of belt pulleys 201g. A third motor 201i is fixedly disposed on the side of the push plate 201c close to the connecting sleeve 103b, and the output end of the third motor 201i is fixedly connected to the lower rotating shaft 201e, so as to drive the polishing head 201f to rotate and grind the surface of the steel bar.

[0056] It should be noted that the two groups of belt pulleys 201g are respectively disposed on the outer sides of the two groups of rotating shafts 201e, and the two groups of belt pulleys 201g are connected by a belt 201h. The belt pulley 201g and the belt 201h are designed with a wrap angle; the third motor 201i is the same as the second motor 102d-4 and the first motor 101c-3, and is powered by an external power supply and controlled by a built-in switch. When the third motor 201i is started, it will drive the lower rotating shaft 201e to rotate. When the rotating shaft 201e rotates, it will drive the belt pulley 201g connected thereto to rotate, and the belt 201h drives the other group of belt pulley 201g and the rotating shaft 201e to rotate synchronously, so that both groups of polishing heads 201f can rotate to rotate and grind the exposed surface of the steel bar.

[0057] Further, the dust cleaning assembly 202 includes a second fixing piece 202a disposed on the right inner wall of the connecting sleeve 103b, a blow nozzle 202b disposed on the side of the second fixing piece 202a close to the polishing head 201f, and a blower 202c disposed on the outer side of the connecting sleeve 103b.

[0058] It should be noted that the nozzle 202b is used to output the air flow input by the fan 202c, and the nozzle 22b is designed facing the polishing assembly 201. Driven by the rotating assembly 102, the air flow output by the nozzle 202b can act on the surface of the embedded steel bar after polishing to remove the surface dust, and the dust will be carried away with the discharge of the air flow, thus not affecting the subsequent paint spraying.

[0059] Furthermore, the spraying assembly 203 includes two groups of third fixing pieces 203a arranged inside the connecting assembly 103 and below the polishing assembly 201 and the dust cleaning assembly 202, conveying pipes 203b respectively arranged inside the two groups of third fixing pieces 203a for conveying paint, and several groups of spray heads 203c respectively communicated and arranged outside the two groups of conveying pipes 203b for uniformly spraying the paint. The bottoms of the two groups of conveying pipes 203b are communicated with a tee 203d, and the bottom of the tee 203d is communicated with a universal pipe joint 203e to avoid winding of the paint conveying pipes.

[0060] It should be noted that the universal pipe joint 203c is used to connect with the external paint supply pipe, and the paint supply pipe pumps paint to the conveying pipe 203b driven by an external pump body. Since the universal pipe joint 203c has the characteristic of being rotatable, it can avoid the situation that the paint supply pipe is wound and knotted during the rotating spraying process, which affects the normal conveying of the paint; the tee 203d can divide the pumped paint and convey it into the two groups of conveying pipes 203b for bilateral synchronous spraying, improving the spraying efficiency.

[0061] During use, the vertical lifting of the rotating assembly 102 is realized by starting the first motor 101c-3 to drive the winding roller 101c-5 to rotate forward or backward. Specifically, when the first motor 101c-3 rotates forward, the winding roller 101c-5 rotates clockwise to wind the towing rope 101c-6. As the length of the towing rope 101c-6 decreases, the slider 102a moves upward along the cavity 101b, thereby driving the rust prevention unit 200 to rise vertically. When the first motor 101c-3 rotates backward, the winding roller 101c-5 rotates counterclockwise to release the wound towing rope 101c-6. Under the action of the increase in the length of the towing rope 101c-6 and gravity, the slider 102a moves downward along the cavity 101b, thereby driving the rust prevention unit 200 to descend vertically. The above can operate according to the exposed length of the embedded steel bar to adjust the vertical height of the rust prevention unit 200; when treating the surface of the embedded steel bar, by starting the second motor 102d-4 to drive the gear 102d-6 and the externally toothed ring 102d-3 meshed with it to rotate, and then driving the rust prevention unit 200 connected to the rotating ring 102d-2 through the connecting assembly 103 to rotate circumferentially by the rotating ring 102d-2 for multi-angle treatment of the exposed surface of the steel bar;

[0062] The polishing assembly 201 is first pushed by the spring 201b to make the polishing head 201f fit against the exposed surface of the embedded steel bar. Subsequently, the third motor 201i is started to drive the rotation of the lower rotating shaft 201e. When the rotating shaft 201e rotates, it drives the pulley 201g connected thereto to rotate, and the belt 201h drives another set of pulleys 201g to rotate synchronously with the rotating shaft 201e, so that both sets of polishing heads 201f rotate to perform rotary grinding on the exposed surface of the steel bar. Under the combined action of the above-mentioned traction member 101c and the rotating assembly 102, the polishing head 201f performs meticulous grinding on the steel bar surface in multiple directions and at multiple angles. The nozzle 202b is used to output the air flow input by the blower 202c, and the nozzle 22b is designed facing the polishing assembly 201. Driven by the rotating assembly 102, the air flow output by the nozzle 202b can act on the surface of the embedded steel bar after polishing to remove surface dust, and the dust will be carried away with the discharge of the air flow, thus not affecting the subsequent paint spraying. The universal pipe joint 203c is used to connect with the external paint supply pipe, and the paint supply pipe is driven by an external pump to pump paint liquid into the delivery pipe 203b. The three-way pipe 203d can divide the pumped paint liquid and convey it into the two groups of delivery pipes 203b. Since the pumped paint liquid contains pressure, when it is divided and conveyed into the two groups of delivery pipes 203b, it will be sprayed out from a number of nozzles 203c onto the surface of the steel bar to form a paint layer for rust prevention of the steel bar.

[0063] In summary, by starting the first motor 101c-3 to drive the winding roller 101c-5 to rotate forward or backward, the vertical lifting of the rotating assembly 102 is realized, and the vertical height of the rust prevention unit 200 can be adjusted according to the exposed length of the embedded steel bar. When treating the surface of the embedded steel bar, by starting the second motor 102d-4 to drive the gear 102d-6 and the externally meshed gear ring 102d-3 to rotate, the rust prevention unit 200 is driven to rotate circumferentially to process the exposed surface of the steel bar from multiple angles. Under the combined action of the above-mentioned traction member 101c and the rotating assembly 102, the polishing head 201f can perform meticulous grinding on the steel bar surface in multiple directions and at multiple angles. At the same time, driven by the rotating assembly 102, the air flow output by the nozzle 202b can act on the surface of the embedded steel bar after polishing to remove surface dust. The paint liquid is sprayed onto the surface of the steel bar through a number of nozzles 203c to form a paint layer for rust prevention of the steel bar, and the universal pipe joint 203c has the characteristic of being rotatable, so the situation that the paint supply pipe is wound and knotted, etc., which affects the normal delivery of the paint liquid, can be avoided during the rotating spraying process.

[0080] Furthermore, the polishing component 201 further includes two groups of rotating holes 201d opened on the outer side of the push plate 201c, rotating shafts 201e respectively rotatably arranged inside the two groups of rotating holes 201d, and polishing heads 201f respectively fixedly provided at the right ends of the two groups of rotating shafts 201e.

[0081] It should be noted that the two groups of belt pulleys 201g are respectively arranged on the outer sides of the two groups of rotating shafts 201e, and the two groups of belt pulleys 201g are connected by a belt 201h. The belt pulley 201g and the belt 201h are designed with a wrap angle; the third motor 201i is the same as the second motor 102d-4 and the first motor 101c-3, and all are powered by an external power supply and controlled by a built-in switch. When the third motor 201i is started, it will drive the lower rotating shaft 201e to rotate. When the rotating shaft 201e rotates, it will drive the belt pulley 201g connected thereto to rotate, and the belt 201h will drive the other group of belt pulley 201g and the rotating shaft 201e to rotate synchronously, so that both groups of polishing heads 201f can rotate to rotate and polish the exposed surface of the steel bar.

[0082] Further, the dust cleaning assembly 202 includes a second fixing piece 202a disposed on the right inner wall of the connecting sleeve 103b, a blowing nozzle 202b disposed on the side of the second fixing piece 202a close to the polishing head 201f, and a blower 202c disposed on the outer side of the connecting sleeve 103b.

[0083] It should be noted that the blowing nozzle 202b is used to output the air flow input by the blower 202c, and the blowing nozzle 22b is designed facing the polishing assembly 201. Driven by the rotating assembly 102, the air flow output by the blowing nozzle 202b can act on the surface of the embedded steel bar after polishing to remove the surface dust, and the dust will be carried away with the discharge of the air flow, thus not affecting the subsequent paint spraying.

[0084] Further, an air supply pipe 202c-1 is connected to the air outlet side of the blower 202c, and one end of the air supply pipe 202c-1 away from the blower 202c is connected to the blowing nozzle 202b for providing a gas source to the blowing nozzle 202b.

[0085] Further, the spraying assembly 203 includes two groups of third fixing pieces 203a disposed inside the connecting assembly 103 and below the polishing assembly 201 and the dust cleaning assembly 202, a conveying pipe 203b disposed inside each of the two groups of third fixing pieces 203a for conveying paint, and a number of spray heads 203c respectively connected to the outer sides of the two groups of conveying pipes 203b for uniformly spraying the paint. The bottom ends of the two groups of conveying pipes 203b are connected to a three-way pipe 203d, and the bottom end of the three-way pipe 203d is connected to a universal pipe joint 203e to avoid winding of the paint conveying pipes.

[0086] It should be noted that the universal pipe joint 203c is used to connect with an external paint supply pipe, and the paint supply pipe is driven by an external pump to pump paint to the conveying pipe 203b. The universal pipe joint 203c has a rotatable characteristic, so it can avoid the situation that the paint supply pipe is wound and knotted during the rotating spraying process, which affects the normal conveying of the paint; the three-way pipe 203d can divide the pumped paint and convey it into the two groups of conveying pipes 203b for bilateral synchronous spraying, improving the spraying efficiency.

[0087] Further, the number of spray heads 203c are arranged at intervals along the length directions of the two groups of conveying pipes 203b.

[0088] It should be noted that the third motor 201i is the same as the second motor 102d-4 and the first motor 101c-3, and they are all small servo motors and are all common models on the market. The universal pipe joint 203c is composed of two pipes connected by a ball head, and a hose is installed inside the ball head and penetrates and connects the two pipes as a liquid flow path. Its ball head structure enables the two pipes to have a rotatable characteristic.

[0089] During use, the anti-rust unit 200 and the like are sleeved on the outside of the embedded exposed steel bars through the support assembly 101 and supported as a whole. Then, the polishing assembly 201 and the dust cleaning assembly 202 are started in sequence. The polishing assembly 201 contacts the surface of the steel bar for polishing to remove the rust layer and impurities formed on the surface of the steel bar. Among them, the vertical lifting of the rotating assembly 102 is realized by starting the first motor 101c-3 to drive the winding roller 101c-5 to rotate forward or backward. Specifically, when the first motor 101c-3 rotates forward, the winding roller 101c-5 rotates clockwise to wind the traction rope 101c-6. As the length of the traction rope 101c-6 decreases, the slider 102a is driven to move upward along the cavity 101b, and then the anti-rust unit 200 is driven to rise vertically. When the first motor 101c-3 rotates backward, the winding roller 101c-5 rotates counterclockwise to release the wound traction rope 101c-6. Under the action of the increase in the length of the traction rope 101c-6 and gravity, the slider 102a is driven to move downward along the cavity 101b, and then the anti-rust unit 200 is driven to descend vertically. The above can operate according to the exposed length of the embedded steel bar to adjust the vertical height of the anti-rust unit 200; when treating the surface of the embedded steel bar, the second motor 102d-4 is started to drive the gear 102d-6 and the outer tooth ring 102d-3 meshed with it to rotate. Then, the anti-rust unit 200 connected to the rotating ring 102d-2 through the connecting assembly 103 is driven to rotate circumferentially by the rotating ring 102d-2 for multi-angle treatment of the exposed surface of the steel bar;

[0090] The polishing assembly 201 is first pushed by the spring 201b to make the polishing head 201f fit against the exposed surface of the embedded steel bar. Subsequently, the third motor 201i is started to drive the rotation of the lower rotating shaft 201e. When the rotating shaft 201e rotates, it drives the pulley 201g connected thereto to rotate, and the belt 201h drives another set of pulleys 201g to rotate synchronously with the rotating shaft 201e, so that both sets of polishing heads 201f rotate to perform rotary grinding on the exposed surface of the steel bar. Under the combined action of the above-mentioned traction member 101c and the rotating assembly 102, the polishing head 201f performs meticulous grinding on the steel bar surface in multiple directions and at multiple angles. The nozzle 202b is used to output the air flow input by the fan 202c, and the nozzle 22b is designed facing the polishing assembly 201. Driven by the rotating assembly 102, the air flow output by the nozzle 202b can act on the surface of the embedded steel bar after polishing to remove the surface dust, and the dust will be carried away with the discharge of the air flow, thus not affecting the subsequent paint spraying. The universal pipe joint 203c is used to connect with the external paint supply pipe, and the paint supply pipe is driven by an external pump to pump the paint liquid into the delivery pipe 203b. The tee 203d can divide the pumped paint liquid and transport it into the two groups of delivery pipes 203b. Since the pumped paint liquid contains pressure, it will be ejected from several groups of nozzles 203c onto the surface of the steel bar under the action of pressure when being divided and transported into the two groups of delivery pipes 203b to form a paint layer for rust prevention of the steel bar.

[0091] In summary, using the polishing assembly 201 to polish the exposed surface of the embedded steel bar can effectively clean the rust layer and stains attached to the exposed surface of the steel bar, which can avoid the phenomenon that the paint liquid cannot be effectively rust-proof protected when being sprayed onto impurities during spraying. At the same time, the dust cleaning assembly 202 can further clean the dust on the basis of the polishing assembly 201 to ensure that the rust-proof paint layer can better adhere to the exposed surface of the steel bar. The double-sided design of the spraying assembly 203 can spray the exposed surface of the steel bar multiple times within the same rotation cycle, making the rust-proof paint layer more uniform and thicker. The support assembly 101 and the rotating assembly 102 provide adjustments in the vertical and horizontal circumferential directions for the rust prevention unit 200, enabling the rust prevention unit 200 to perform dead-angle-free grinding and cleaning as well as paint layer spraying operations on the exposed surface of the steel bar. Compared with the prior art, it cleans the exposed surface of the steel bar more meticulously and thoroughly, and sprays the rust-proof paint layer more evenly and precisely, improving the rust prevention protection effect and protection life of the exposed steel bar.
