Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a device for preventing the corrosion of reinforcing bars and steel components. Background Technology

[0002] In construction engineering, steel bars and steel components are indispensable building materials in modern architecture. Corrosion of steel bars and components is the most significant and direct factor causing damage to the durability of building structures. On some construction sites, when steel bars and components are left unused for extended periods due to work stoppage, their surfaces can rust due to moisture. To protect them from corrosion, construction workers typically cover the steel with waterproof plastic film to reduce the possibility of corrosion. However, this method is cumbersome in practice, and because plastic film cannot completely isolate moisture from the air, its protective effect is unsatisfactory.

[0003] To improve the protection of reinforcing bars and steel components, a Chinese patent with publication number CN114769025A proposes a device for preventing corrosion of reinforcing bars and steel components. This device "includes a movable support, on which a material bucket for holding cement slurry is mounted; a spray pipe for connecting the material bucket's cavity is mounted on the material bucket, and a nozzle is fixed to one end of the spray pipe." It uses an air compressor to evenly spray the cement slurry from the material bucket onto the reinforcing bars and steel components, giving them a protective film that isolates them from the outside environment. This effectively improves the corrosion resistance of the reinforcing bars and steel components. Furthermore, the direct spraying of the cement slurry through the nozzle makes the operation convenient.

[0004] While the aforementioned equipment has solved the problem of steel corrosion to some extent, it still has the following shortcomings:

[0005] First, because the stirring area of ​​the stirring rod is limited, the stirring angle of the stirring rod can only be adjusted by manually adjusting the adjustment component, which is very troublesome.

[0006] Second: Since the position of the material bucket cannot be changed, the height of the nozzle cannot be changed. When the steel is at different heights on the ground, the nozzle cannot effectively spray the steel, affecting the spraying effect.

[0007] Therefore, it is necessary to invent a device to prevent the corrosion of steel bars and steel components to solve the above problems. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a device for preventing corrosion of reinforcing bars and steel components, thereby solving the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a device for preventing corrosion of reinforcing bars and steel components, comprising a movable base, a push rod fixedly connected to the top of the movable base, the push rod comprising an inclined section and a horizontal section, and a storage tank for holding cement slurry provided on the inclined section of the push rod, a spray pipe connected to the bottom of the storage tank, and a nozzle connected to the end of the spray pipe, a stirring device for stirring cement slurry provided inside the storage tank, a transmission component for moving the storage tank provided at a position opposite to the inclined section of the push rod, an air compressor provided at the bottom of the horizontal section of the push rod, the air compressor being mounted on the movable base, and a connecting pipe for spraying cement slurry from the storage tank connecting the air compressor and the storage tank.

[0010] Furthermore, the stirring device includes a first stirring shaft, which is inclinedly inserted into the storage tank. The portion of the first stirring shaft inside the storage tank is equipped with auger blades. A first motor is connected to the top of the first stirring shaft. A fixing plate is provided on the side of the first motor near the inclined section of the push rod. The fixing plate is fixedly connected to the top edge of the storage tank, and the first motor is detachably mounted on the fixing plate. A rotating ring is rotatably installed at the inner edge of the top of the storage tank. Multiple second stirring shafts are rotatably connected to the bottom of the rotating ring via a torsion spring. The second stirring shafts are parallel to the inner wall of the storage tank. A fixing block is rotatably connected to the bottom of the second stirring shaft, and the fixing block is fixedly connected to the inner wall of the storage tank. First teeth are evenly arranged on the inner side of the rotating ring. A first gear is fixedly sleeved at the position opposite to the first teeth on the first stirring shaft, and the first gear meshes with the first teeth.

[0011] Furthermore, the transmission assembly includes a transmission shaft located on the side of the inclined section of the push rod away from the storage tank, and parallel to the inclined section of the push rod. A second motor is connected to the top of the transmission shaft and is mounted on the inclined section of the push rod. A strip-shaped through hole is provided at the position opposite to the push rod on the inclined section of the push rod. A screw is rotatably connected between the top and bottom walls of the through hole. A movable block is threaded onto the screw and connected to the storage tank. A second gear is sleeved near the top of the screw, and a third gear is sleeved on the transmission shaft at the corresponding position of the second gear, with the second gear meshing with the third gear.

[0012] Furthermore, a lever is fixedly connected to the second stirring shaft, and the lever is perpendicular to the inner wall of the storage tank. A fourth gear is sleeved on the second stirring shaft near the top. An annular protective cover is fixedly connected to the inner edge of the top of the storage tank, and both the rotating ring and the fourth gear are surrounded by the protective cover. The protective cover has a notch that matches the first gear at the position opposite to the first gear. A second tooth is provided on the side of the protective cover near the fourth gear, and the second tooth can mesh with the fourth gear.

[0013] Furthermore, a slider is fixedly connected to the storage tank at a position opposite to the movable block. The slider is slidably mounted on the movable block. A support plate is provided at the bottom of the storage tank. Multiple telescopic rods are obliquely fixedly connected between the support plate and the top of the movable base. The telescopic rods are parallel to the inclined section of the push rod, and shock-absorbing springs are sleeved on the telescopic rods.

[0014] Furthermore, a U-shaped limiting hoop is fixedly connected to the side of the support plate near the push rod, and the limiting hoop is slidably sleeved on the inclined section of the push rod.

[0015] Furthermore, the width of the deflector plate is greater than the distance between the auger blades and the storage tank, and the thickness of the deflector plate is less than the distance between the auger blades and the storage tank.

[0016] Furthermore, the second tooth is located on the side of the notch closest to the rotation direction of the rotating ring, and the maximum angle at which the second tooth drives the fourth gear to rotate is ninety degrees.

[0017] Furthermore, the maximum distance the slider travels along the movable block is greater than the maximum extension / retraction of the telescopic rod.

[0018] The technical effects and advantages of this invention are as follows:

[0019] 1. When mixing cement slurry, as the first motor starts, the first mixing shaft can drive the auger to rotate under the action of the first motor. At the same time, multiple second mixing shafts can stir the cement slurry away from the auger blades along the inner wall of the storage tank under the drive of the rotating ring. This, in conjunction with the auger blades, improves the mixing effect of the cement slurry. In addition, since the cement slurry in the storage tank can be stirred by the auger blades and the second mixing shafts, the adjustment of the mixing angle of the first mixing shaft is avoided. Thus, while ensuring the mixing efficiency, the spraying efficiency of the steel is improved.

[0020] 2. The present invention has a transmission component. Before spraying cement slurry onto the steel, the storage tank is moved to the bottom position by the transmission component, so as to facilitate the addition of cement slurry raw materials into the storage tank. After the cement slurry is added, the transmission component is restarted to adjust the spraying height of the nozzle according to the height of the steel, so that the steel can be better sprayed with cement slurry.

[0021] 3. By providing a deflector plate, during the process of the rotating ring driving the second stirring shaft to agitate the cement slurry, the deflector plate can increase the contact area between the second stirring shaft and the cement slurry. In addition, during the movement of the deflector plate, when the fourth gear contacts the second tooth, the deflector plate can gradually adhere to the inner wall of the storage tank under the cooperation of the fourth gear and the second tooth, thus ensuring that the deflector plate does not contact the auger blades. When the fourth gear separates from the second tooth, the second stirring shaft can drive the deflector plate to return to its initial state under the action of the torsion spring, thereby improving the mixing efficiency of the cement slurry in conjunction with the second stirring shaft.

[0022] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description and drawings. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention provides, for example Figures 1 to 7 The device shown includes a movable base 1, a push rod 2 fixedly connected to the top of the movable base 1, the push rod 2 including an inclined section and a horizontal section, and a storage tank 3 for holding cement slurry is provided on the inclined section of the push rod 2. A spray pipe 4 is connected to the bottom of the storage tank 3, and a nozzle 5 is connected to the end of the spray pipe 4. A stirring device 6 for stirring cement slurry is provided inside the storage tank 3. A transmission component 7 for moving the storage tank 3 is provided at the position opposite to the inclined section of the push rod 2. An air compressor 8 is provided at the bottom of the horizontal section of the push rod 2. The air compressor 8 is mounted on the movable base 1, and a connecting pipe 9 for spraying cement slurry from the storage tank 3 is connected between the air compressor 8 and the storage tank 3.

[0034] Before spraying cement slurry onto the steel, the storage tank 3 is moved to the bottom position by the transmission component 7 to facilitate the addition of cement slurry raw materials into the storage tank 3. After the cement slurry is added, the transmission component 7 is restarted to adjust the spraying height of the nozzle 5 according to the height of the steel, so that the steel can be better sprayed with cement slurry.

[0035] During spraying, the mixing device 6 and the air compressor 8 are started in sequence, so that the mixed cement slurry can be evenly sprayed onto the steel surface through the nozzle 5 under the action of the air compressor 8, thereby improving the steel's anti-corrosion effect.

[0036] like Figures 2 to 6As shown, the transmission assembly 7 includes a transmission shaft 71, which is located on the side of the inclined section of the push rod 2 away from the storage tank 3 and is parallel to the inclined section of the push rod 2. A second motor 72 is connected to the top of the transmission shaft 71 and is mounted on the inclined section of the push rod 2. A strip-shaped through hole is opened through the inclined section of the push rod 2 opposite to the push rod 2. A screw 73 is rotatably connected between the top and bottom walls of the through hole. A movable block 74 is threaded onto the screw 73 and is connected to the storage tank 3. A second gear 75 is sleeved near the top of the screw 73. A third gear 76 is sleeved on the transmission shaft 71 at the corresponding position of the second gear 75, and the second gear 75 and the third gear 76 mesh.

[0037] The stirring device 6 includes a first stirring shaft 61, which is inclinedly inserted into the storage tank 3. The portion of the first stirring shaft 61 inside the storage tank 3 is provided with auger blades 62. A first motor 63 is connected to the top of the first stirring shaft 61. A fixing plate 64 is provided on the side of the first motor 63 near the inclined section of the push rod 2. The fixing plate 64 is fixedly connected to the top edge of the storage tank 3, and the first motor 63 is detachably mounted on the fixing plate 64. A rotating ring 65 is rotatably installed at the inner edge of the top of the storage tank 3. A plurality of second stirring shafts 66 are rotatably connected to the bottom of the rotating ring 65 through a torsion spring. The second stirring shafts 66 are parallel to the inner wall of the storage tank 3. A fixing block is rotatably connected to the bottom end of the second stirring shaft 66, and the fixing block is fixedly connected to the inner wall of the storage tank 3. First teeth are evenly arranged on the inner side of the rotating ring 65. A first gear 67 is fixedly sleeved at the position opposite to the first teeth on the first stirring shaft 61, and the first gear 67 meshes with the first teeth.

[0038] Before spraying cement slurry onto the steel, the second motor 72 is started, causing the drive shaft 71 to rotate through the third gear 76 and the second gear 75 under the action of the second motor 72. As the second gear 75 rotates, the screw 73 can start to rotate under the action of the second gear 75. As the screw 73 rotates, the movable block 74 can drive the storage tank 3 to move downward along the screw 73 under the action of the screw 73. When the storage tank 3 moves to the bottom position, cement slurry material can be easily added into the storage tank 3. After the cement slurry material is added, the second motor 72 is started again and rotated in the opposite direction. Through the cooperation of the screw 73 and the movable block 74, it moves upward. As the storage tank 3 moves upward, the height of the spray pipe 4 and the nozzle 5 also changes accordingly. Thus, the height of the nozzle 5 can be adjusted according to the height of the steel, improving the spraying effect of the nozzle 5 on the steel.

[0039] During spraying, the first motor 63 and the air compressor 8 are started in sequence. With the start of the first motor 63, the first stirring shaft 61 drives the auger blades 62 to rotate, thereby stirring the cement slurry. At the same time, with the rotation of the first stirring shaft 61, the first gear 67 drives the rotating ring 65 to rotate. With the rotation of the rotating ring 65, multiple second stirring shafts 66 can stir the cement slurry away from the auger blades 62 along the inner wall of the storage tank 3 under the drive of the rotating ring 65, thereby improving the stirring effect of the cement slurry in conjunction with the auger blades 62. In addition, since the cement slurry in the storage tank 3 can be stirred by the auger blades 62 and the second stirring shafts 66, the stirring angle of the first stirring shaft 61 is not adjusted, thereby improving the spraying efficiency of the steel while ensuring the stirring efficiency.

[0040] The well-mixed cement slurry can then be sprayed onto the surface of the steel through nozzle 5 under the action of air compressor 8, thereby completing the rust prevention treatment of the steel.

[0041] like Figures 5 to 7 As shown, a lever plate 10 is fixedly connected to the second stirring shaft 66, and the lever plate 10 is perpendicular to the inner wall of the storage tank 3. A fourth gear 11 is sleeved near the top of the second stirring shaft 66. An annular protective cover 12 is fixedly connected to the inner edge of the top of the storage tank 3, and both the rotating ring 65 and the fourth gear 11 are surrounded by the protective cover 12. The protective cover 12 has a notch that matches the first gear 67 at the position opposite to the first gear 67. A second tooth 13 is provided on the side of the protective cover 12 near the fourth gear 11, and the second tooth 13 can mesh with the fourth gear 11. The width of the lever plate 10 is greater than the distance between the auger blade 62 and the storage tank 3, and the thickness of the lever plate 10 is less than the distance between the auger blade 62 and the storage tank 3. The second tooth 13 is located on the side of the notch near the rotation direction of the rotating ring 65, and the maximum angle at which the second tooth 13 drives the fourth gear 11 to rotate is ninety degrees.

[0042] With the addition of the baffle plate 10, as the rotating ring 65 drives the second stirring shaft 66 to stir the cement slurry, the second stirring shaft 66 drives the baffle plate 10 to stir the cement slurry together with the rotation of the rotating ring 65. Since the baffle plate 10 can increase the contact area between the second stirring shaft 66 and the cement slurry, the cement slurry can be stirred faster and more evenly under the combined action of the second stirring shaft 66 and the baffle plate 10.

[0043] Furthermore, during the movement of the paddle plate 10, when the fourth gear 11 contacts the second tooth 13, as the rotating ring 65 continues to rotate, the fourth gear 11 drives the second stirring shaft 66 to rotate under the action of the second tooth 13, thereby enabling the paddle plate 10 to gradually fit against the inner wall of the storage tank 3, thus ensuring that the paddle plate 10 does not contact the auger blade 62. When the fourth gear 11 separates from the second tooth 13, the second stirring shaft 66 can drive the paddle plate 10 to return to its initial state under the action of the torsion spring, thereby improving the mixing efficiency of the cement slurry in conjunction with the second stirring shaft 66.

[0044] In addition, due to the presence of the protective cover 12, the protective cover 12 can protect the rotating ring 65 and the first gear 67, preventing cement slurry from adhering to the rotating ring 65 during the process of adding cement slurry, and ensuring the normal rotation of the rotating ring 65.

[0045] like Figures 2 to 5 As shown, a slider 14 is fixedly connected to the storage tank 3 at a position opposite to the movable block 74. The slider 14 is slidably mounted on the movable block 74. A support plate 15 is provided at the bottom of the storage tank 3. Multiple telescopic rods 16 are obliquely fixedly connected between the support plate 15 and the top of the movable base 1. The telescopic rods 16 are parallel to the inclined section of the push rod 2, and a shock-absorbing spring 17 is sleeved on the telescopic rods 16. A U-shaped limiting hoop 18 is fixedly connected to the side of the support plate 15 near the push rod 2, and the limiting hoop 18 is slidably sleeved on the inclined section of the push rod 2. The maximum distance that the slider 14 moves along the movable block 74 is greater than the maximum extension amount of the telescopic rod 16.

[0046] With the support plate 15, when it is necessary to add raw materials into the storage tank 3, the second motor 72 can be started first, so that the storage tank 3 moves downward under the action of the screw 73. When the storage tank 3 contacts the support plate 15, as the storage tank 3 moves further downward, the storage tank 3 begins to remain stationary due to the support of the support plate 15, while the movable block 74 continues to move downward under the action of the screw 73. At this time, the top and bottom of the slider 14 are no longer restricted by the movable block 74 and are in a free state.

[0047] When the screw 73 stops rotating, the storage tank 3 can be in a lower position under the support of the support plate 15, which makes it easier to add raw materials into the storage tank 3. In addition, when adding raw materials into the storage tank 3, the storage tank 3 will be pressed down due to the impact of the raw materials, so that the telescopic rod 16 and the shock-absorbing spring 17 can begin to contract under the compression of the storage tank 3. At the same time, as the storage tank 3 moves downward, the slider 14 can also move downward relative to the movable block 74, and the impact force on the storage tank 3 can be converted into the elastic potential energy of the shock-absorbing spring 17 by the ring 65, thereby reducing the impact force of the raw materials on the storage tank 3.

[0048] Furthermore, since the connection point between the storage tank 3 and the movable block 74 is in a movable state during the loading process, it is possible to avoid damage to the connection point between the storage tank 3 and the movable block 74 caused by the impact force of the raw material on the storage tank 3, compared to a fixed connection.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
