Description

Technical Field

[0001] The utility model relates to the field of steel bar straightening devices, and particularly relates to a steel bar straightening device for construction sites. Background Technique

[0002] The steel bar straightening device for construction sites is a device used to correct the straightness of steel bars at the construction site, aiming to improve the quality and stability of steel bars. It mainly corrects steel bars through physical actions. Usually, transmission rollers and pressing rollers act on the steel bars simultaneously, so that the steel bars are transmitted from one side of the device to the other side under the action of thrust and pressure, and at the same time, the steel bars are straightened to meet various construction standards and requirements.

[0003] When the traditional steel bar straightening device is in use, the requirement for the internal cleanliness is relatively high. If too much iron filings and other impurities accumulate inside, it is easy to cause situations such as the device getting stuck. Therefore, additional manpower and material resources need to be applied to maintain the device, which is not conducive to the construction efficiency. At the same time, a large amount of dropped impurities or iron filings attached to the outside of the steel bars may cause harm to construction workers. When using steel bars, the rust attached to their outer surface will also reduce the service life of the steel bars. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a steel bar straightening device for construction sites, which can effectively solve the technical problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A steel bar straightening device for construction sites includes a support base. Six support columns are fixedly installed on the upper part of the support base. A number of transmission rollers and pressing rollers are installed in parallel between the six support columns. Two support plates are slidably installed on both sides of the pressing roller and between two support columns. A transmission structure is arranged at the lower side position of the support plate. The transmission structure includes two parallel connecting rods. Connecting plates are fixedly installed on both sides of the two connecting rods. Two transmission rods are rotatably installed in parallel at one side position between the connecting plates on both sides. A conveyor belt is rotatably installed outside the two transmission rods. Springs are fixedly installed on both sides of the transmission rods. The other side of the spring is fixedly installed with a rotating rod. A first roller is rotatably installed at one end of the rotating rod. A transmission gear is rotatably installed inside the conveyor belt between the two connecting plates. Connecting belts are rotatably installed on both sides of the transmission gear. The other side of the connecting belt is rotatably installed with a second roller.

[0007] As a further scheme of the utility model, one end of the spring is installed at the middle position of the rotating rod, the other end of the rotating rod is connected to the connecting plate, and a number of grooves are formed in the middle of the first roller.

[0008] As a further solution of the present utility model, hexagonal prisms are fixedly installed at both ends of the transmission gear and the second roller, and the connecting belt is connected to the transmission gear and the second roller through the hexagonal prisms. A plurality of grooves are formed in the middle of the second roller, and both sides are in the shape of gears.

[0009] As a further solution of the present utility model, a cleaning structure is arranged outside the second roller and between two connecting plates. The cleaning structure includes two folding rods, and third rollers are rotatably installed at one ends of the two folding rods, and steel brushes are fixedly installed on the other sides of the third rollers.

[0010] As a further solution of the present utility model, the outer part of the third roller is in the shape of a gear, and the third roller is meshed with the second roller, and the two steel brushes are arranged in a staggered manner.

[0011] As a further solution of the present utility model, the lower parts of the driving roller, the pressing roller and the second roller are at the same horizontal position, and the pressing rollers are all obliquely and staggeredly installed on the support plate.

[0012] The beneficial effects of the present utility model are as follows: By setting the transmission structure, when the steel bar is transmitted to the pressing roller, it contacts the second roller under the action of the downward pressure of the first gear. Under the action of friction, the second roller rotates, thereby driving the transmission gear, making the conveyor belt roll, and transmitting impurities such as iron filings caused by extrusion or rubbing to the trash can, reducing phenomena such as the device being stuck due to impurity accumulation. The transmission structure is synchronized with the steel bar conveying, replacing the cumbersome manual operation of cleaning the equipment, and making the steel bar straightening more efficient and cost-effective.

[0013] By setting the cleaning structure, when the steel bar is transmitted to the pressing roller, the third roller rotates synchronously under the rotation of the second roller. At the same time, the steel brush on one side of the third roller cleans the steel bar. By setting a number of staggered steel brushes, redundant iron filings, rust and other substances can be actively cleaned during the process of transmitting impurities, avoiding harm to the operator caused by iron filings during later processing. At the same time, cleaning the rust attached to the surface of the steel bar can increase the service life of the steel bar. Description of the Drawings

Specific implementation manner

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0019] As Figures 1 - 3 shown, a steel bar straightening device for construction sites includes a support base 1. Six support columns 2 are fixedly installed on the upper part of the support base 1. A number of transmission rollers 3 and pressing rollers 5 are installed in parallel between the six support columns 2. Two support plates 4 are slidably installed on both sides of the pressing roller 5 and between two support columns 2. A conveying structure 6 is arranged at the lower side position of the support plate 4. The conveying structure 6 includes two parallel connecting rods 7. Connecting plates 8 are fixedly installed on both sides of the two connecting rods 7. Two conveying rods 9 are rotatably installed in parallel at one side position between the connecting plates 8 on both sides. A conveyor belt 10 is rotatably installed outside the two conveying rods 9. Springs 11 are fixedly installed on both sides of the conveying rod 9. The other side of the spring 11 is fixedly installed with a rotating rod 12. One end of the rotating rod 12 is rotatably installed with a first roller 13. A transmission gear 14 is rotatably installed between the two connecting plates 8 and inside the conveyor belt 10. Connecting belts 15 are rotatably installed on both sides of the transmission gear 14. The other side of the connecting belt 15 is rotatably installed with a second roller 16.

[0020] In this embodiment, one end of the spring 11 is installed at the middle position of the rotating rod 12. The other end of the rotating rod 12 is connected to the connecting plate 8. A number of grooves are formed in the middle of the first roller 13.

[0021] In order to make the steel bar fit more closely to the second roller 16, under the pulling force of the spring 11, the rotating rod 12 rotates downward, and at the same time drives the first roller 13 to apply downward pressure on the steel bar, increasing the friction between the steel bar and the second roller 16. Under the action of the movement of the steel bar, the second roller 16 rotates accordingly.

[0022] In this embodiment, hexagonal prisms are fixedly installed at both ends of the transmission gear 14 and the second roller 16. The connecting belt 15 is connected to the transmission gear 14 and the second roller 16 through the hexagonal prisms. A number of grooves are formed in the middle of the second roller 16 and the two sides are in the shape of gears.

[0023] When the second roller 16 rotates, in order to achieve the synchronous rotation of the conveying gear 14, hexagonal prisms are installed at both ends of the conveying gear 14 and the second roller 16. The function of the hexagonal prism is to drive the rotation of the connecting belt 15. Therefore, when the second roller 16 rotates, the conveying gear 14 also rotates, and thus the conveyor belt 10 also rotates, conveying the iron filings or dirt generated during the straightening process to the trash can. The purpose of arranging a number of grooves in the middle of the second roller 16 is to increase the friction with the steel bar.

[0024] In this embodiment, a cleaning structure 17 is arranged outside the second roller 16 and between two connecting plates 8. The cleaning structure 17 includes two folding rods 18. A third roller 19 is rotatably installed at one end of each of the two folding rods 18, and a steel brush 20 is fixedly installed on the other side of the third roller 19.

[0025] In this embodiment, the outside of the third roller 19 is in the shape of a gear, and the third roller 19 is meshed and connected with the second roller 16, and the two steel brushes 20 are arranged in a staggered manner.

[0026] The third roller 19 is meshed and connected with the second roller 16, which can drive the third roller 19 while the second roller 16 rotates. The steel brush 20 on one side of the third roller 19 cleans the steel bar. The purpose of arranging the two steel brushes 20 in a staggered manner is to make the cleaning more thorough.

[0027] In this embodiment, the lower parts of the driving roller 3, the pressing roller 5 and the second roller 16 are at the same horizontal position, and the pressing rollers 5 are all installed on the support plate 4 in an inclined and staggered manner.

[0028] To ensure that the conveying of the steel bar is in a straight line, the lower parts of the driving roller 3, the pressing roller 5 and the second roller 16 are at the same horizontal position to avoid situations such as the device being stuck due to misalignment. The pressing rollers 5 are all installed on the support plate 4 in an inclined and staggered manner, so as to straighten the steel bar at different angles.

[0029] It should be noted that the present utility model is a steel bar straightening device for construction sites. When in use, in order to make the steel bar fit more closely to the second roller 16, under the pulling force of the spring 11, the rotating rod 12 rotates downward, and at the same time drives the first roller 13 to apply downward pressure on the steel bar, increasing the friction between the steel bar and the second roller 16. Under the action of the moving steel bar, the second roller 16 rotates accordingly. When the second roller 16 rotates, in order to achieve the synchronous rotation of the transmission gear 14, hexagonal prisms are installed at both ends of the transmission gear 14 and the second roller 16. The function of the hexagonal prism is to drive the rotation of the connecting belt 15. Therefore, when the second roller 16 rotates, the transmission gear 14 also rotates, and thus the conveyor belt 10 also rotates accordingly, transporting the iron filings or dirt generated during the straightening process to the trash can. The purpose of opening several grooves in the middle of the second roller 16 is to increase the friction with the steel bar. The third roller 19 is meshed with the second roller 16 and can be driven while the second roller 16 rotates. The steel brush 20 on one side of the third roller 19 cleans the steel bar. The purpose of arranging the steel brushes 20 on both sides in a staggered manner is to make the cleaning more thorough.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
