[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1

[0030] like Figures 1 to 2 As shown in the embodiment of the present invention, a protective device for a straightening machine includes multiple protective railings 1 arranged in parallel and at equal intervals. The protective railings 1 are arranged in an arch shape. Each end of the protective railing 1 is provided with a fixed seat 5, and both ends of the protective railing 1 are rotatably connected to the fixed seat 5. Multiple protective ropes 2 are connected between adjacent protective railings 1. Each end of the protective railing 1 is provided with a power component, which is used to control the raising and lowering of the protective railing 1.

[0031] When working, the straightening machine generally directly inserts the end of a ring of steel bars into the straightening machine when straightening the steel bars. The steel bars continuously entering the straightening machine are exposed on the outside, which is easy to hurt the passing workers. The general protective device is often integrally arranged, which occupies a lot of space and is not convenient to move. Through the arrangement of multiple protective fences 1, when protection is needed, the power assembly is used to drive multiple protective fences 1 to stand up. The moving steel bars are inside multiple protective fences 1, which greatly reduces the problem of the moving steel bars contacting the workers. At the same time, the protective ropes 2 between adjacent protective fences 1 can also improve the protection area. When protection is not needed, the power assembly is used to make the protective fence 1 inclined. Under the action of gravity, multiple protective fences 1 will rotate to a horizontal state. In combination with the arched arrangement of the protective fence 1, the inclined protective fence 1 will be neatly arranged and will not interfere with each other. This arrangement not only realizes the protection function when the straightening machine is working, but also can be placed horizontally when not in use, without affecting other work and personnel passing.

[0032] As shown in Figures 1 to 3 , the power assembly comprises an operation box 4, a winding roller is rotationally connected to the inside of the operation box 4, a handle 8 is fixedly connected to the end of the winding roller, the handle 8 is arranged on the outside of the operation box 4, a connecting belt 10 is fixedly connected to the outside of the winding roller, the connecting belt 10 is woven from flexible fiber material, the connecting belt 10 is arranged in a flat shape, both ends of the protective fence 1 pass through the fixed seat 5 and are fixedly connected with the rotating shaft 11, the bottom of the connecting belt 10 is fixedly connected with multiple separation belts 12, the material of the separation belt 12 is the same as that of the connecting belt 10, and the end of the separation belt 12 is fixedly connected with the outside of the rotating shaft 11;

[0033] When working, the horizontal protective fence 1 needs to be rotated to the horizontal state. Only the handle 8 needs to be rotated, so as to rotate the winding roller to wind the connecting belt 10. With the movement of the connecting belt 10, the separation belt 12 will move in the same direction. The separation belt 12 is partially wound on the outside of the rotating shaft 11. With the movement of the separation belt 12, the rotating shaft 11 will rotate, thereby driving the protective fence 1 to rotate from the horizontal state to the vertical state. The surface of the operation box 4 is provided with a lock catch for fixing the handle 8 that has been rotated in place, so as to prevent the protective fence 1 from collapsing after being vertically arranged. At the same time, the end of the protective fence 1 located at the rotating part of the fixed seat 5 is limited to rotate only by ninety degrees, so as to prevent the protective fence 1 from being excessively rotated.

[0034] As shown in Figures 1 to 4 , it also comprises a placing seat 3, the placing seat 3 is arranged in a disc shape, a dispersion arm 13 is connected to the middle of the top surface of the placing seat 3, the dispersion arm 13 is arranged in a cylindrical shape, the dispersion arm 13 is made of elastic material, a rotating assembly is arranged at the bottom of the dispersion arm 13, the rotating assembly is used to drive the dispersion arm 13 to rotate and swing, a vibration assembly is arranged in the dispersion arm 13, and the vibration assembly is used to make the surface of the dispersion arm 13 vibrate;

[0035] In work, the reinforcement is generally inserted into the straightening machine when feeding the straightening machine, and the straightening machine is continuously pulled until the whole coil of reinforcement is pulled out. However, when the coil of reinforcement is wound together, it is easy to entangle with each other, which causes the whole coil of reinforcement to be dragged together during the pulling process, resulting in accidents. Therefore, a worker needs to constantly move the reinforcement or observe during the general straightening process. Through the arrangement of the dispersion arm 13, the coil of reinforcement is sleeved outside the dispersion arm 13, and then the driving rotating assembly and the vibrating assembly are used to make the dispersion arm 13 rotate conically with the bottom as the fulcrum, and the vibration assembly makes the surface of the dispersion arm 13 vibrate. The dispersion arm 13 in rotation will continuously contact the outer edge of the coil of reinforcement, and the combination between the reinforcements is dispersed under the action of vibration, so that the reinforcement can be smoothly pulled out by the straightening machine, thereby further protecting the safety of the straightening machine during work.

[0036] As shown in Figures 5 to 6 , the rotating assembly comprises a motor box 16, the inside of the motor box 16 is fixedly connected with a driving motor, the output end of the driving motor is vertically downward, the output end of the driving motor is fixedly connected with a transmission rod 20, the outer side of the transmission rod 20 is rotationally connected with a pinion 19, the outer side of the pinion 19 is engaged with a gear 24, a hole penetrating through the top surface to the bottom surface is formed in the top surface of the gear 24, the hole is located on one side of the center of the gear 24, and the dispersion arm 13 penetrates through the hole of the gear 24.

[0037] In work, the transmission rod 20 and the pinion 19 are driven to rotate by the driving of the driving motor, and then the gear 24 is driven to rotate. Since the dispersion arm 13 is inserted in the hole of the gear 24, the dispersion arm 13 can be driven to rotate and swing with the rotation of the gear 24, achieving the effect that the outer ring of the dispersion arm 13 directly contacts the coil of reinforcement.

[0038] As shown in Figures 5 to 6 , the inside of the placing seat 3 is fixedly connected with a rotating seat 28, a semispherical groove is formed in the top surface of the rotating seat 28, and the bottom of the dispersion arm 13 is fixedly connected with a solid ball. The solid ball is rotationally connected with the rotating seat 28 through the groove. In work, the solid ball is limited in the groove by the rotating seat 28, but can rotate, so as to make the dispersion arm 13 swing and limit the position of the bottom of the dispersion arm 13, so that it will not be thrown out.

[0039] As shown in Figures 5 to 6As shown, the top of the placement seat 3 is fixed with a stable frame 15, the dispersion arm 13 passes through the stable frame 15, the top surface of the large gear 24 is fixed with a snap ring 25, the snap ring 25 is slidingly connected with the bottom surface edge of the stable frame 15, the middle part of the large gear 24 is fixed with a limiting rod 26, the bottom of the limiting rod 26 passes through the bottom of the large gear 24 and movably abuts against the top surface of the solid ball at the bottom of the dispersion arm 13. In working, the snap ring 25 is clamped by the stable frame 15, so that the large gear 24 can only rotate, the limiting rod 26 extending downward from the large gear 24 abuts against the solid ball, so that the solid ball and the dispersion arm 13 cannot be pulled out, but can rotate, thereby ensuring the normal working process of the dispersion arm 13.

[0040] As shown, Figures 5 to 6 The inner side of the dispersion arm 13 is provided with a plurality of vibration holes, the vibration holes are equidistantly arranged in the dispersion arm 13, the vibration assembly comprises a rotating rope 22, the rotating rope 22 is located in the middle part of the dispersion arm 13 and movably connected with the inner wall of the dispersion arm 13, the rotating rope 22 passes through the vibration holes, the outer side of the rotating rope 22 is fixed with a plurality of impact arms 23, the impact arms 23 are located in the vibration holes, the bottom of the rotating rope 22 passes through the bottom of the solid ball and the rotating seat 28, the bottom of the rotating rope 22 is provided with a driving assembly, the driving assembly is used for driving the rotating rope 22 to rotate. In working, the rotating rope 22 is driven to rotate by the driving assembly, and then the plurality of impact arms 23 are driven to rotate in the dispersion arm 13. Since the gravity center of the dispersion arm 13 moves outward, the vibration effect is brought to the whole elastic dispersion arm 13 in the rotating process, the vibration effect is transmitted to the reinforcement roll, so that the reinforcement can be effectively dispersed and uniformly pulled out, and the problem that the whole reinforcement roll is pulled is reduced, and the whole process does not need manual participation.

[0041] As shown, Figures 5 to 6 The driving assembly comprises a transmission rope 21, one end of the transmission rope 21 is fixed with the bottom end of the transmission rod 20, the other end of the transmission rope 21 is fixed with the rotating rope 22, the outer side of the transmission rope 21 is sleeved with a plurality of limiting rings 27, the adjacent vibration holes are not communicated, in working, when the pinion 19 rotates, the transmission rod 20 drives the transmission rope 21 to rotate, the rotation is transmitted to the rotating rope 22 to realize the rotating vibration effect, through the setting, the power source is not needed, when the large gear 24 works, the impact arms 23 can also rotate.

[0042] As shown, Figures 1 to 3As shown, the top of the guardrail 1 is fixed with an air extractor 7, the air extractor 7 is provided with a separation cloth bag, the top of the guardrail 1 is fixed with a clamping seat 6, the side away from the air extractor 7 of the clamping seat 6 is provided with an opening, the outer side of the guardrail 1 is provided with a plurality of movable grooves 9, the guard rope 2 is located in the movable groove 9, during work, the metal iron filings generated during work are absorbed by the air extractor 7 to reduce air pollution, and the clamping seat 6 can correspond to the position of the dispersing arm 13 to enable the placement seat 3 to be stored below the guardrail 1, and the movable groove 9 can enable the guard rope 2 to move therein when the guardrail 1 is horizontal, thereby reducing the bending force of the guard rope 2.

[0043] Example two

[0044] As Figure 4 shown, the other embodiment of the present application is as follows: the both ends of the placement seat 3 are fixed with a plurality of butt plates 14, the butt plates 14 are vertically arranged, the surface of the butt plate 14 is provided with a butt hole, one side of the placement seat 3 is provided with two trolleys 17, the top of the trolley 17 is fixed with a jack 18, the outer side of the jack 18 is fixed with a clamping plate matched with the butt plate 14, during work, after the reinforcing steel bar coil is sleeved on the dispersing arm 13, the clamping plate at the end of the jack 18 is fixed with the butt plate 14 through the two trolleys 17, the placement seat 3 is lifted upward by using the jack 18, the two trolleys 17 move the placement seat 3 below the guardrail 1 to complete the transfer work, after the transfer is completed, the placement seat 3 is lowered, and the two trolleys 17 leave.

[0045] When working, the straightening machine generally directly inserts the end of a coil of steel bars into the straightening machine when straightening the steel bars. The steel bars continuously entering the straightening machine are exposed on the outside, which is easy to hurt the passing workers. The general protective device is generally integrally arranged, which occupies a lot of space and is not convenient to move. Through the arrangement of multiple protective fences 1, when protection is needed, the power assembly is used to drive multiple protective fences 1 to stand up. The moving steel bars are inside multiple protective fences 1, which greatly reduces the problem of the moving steel bars contacting the workers. At the same time, the protective ropes 2 between adjacent protective fences 1 can also improve the protection area. When protection is not needed, the power assembly is used to make the protective fence 1 inclined. Under the action of gravity, multiple protective fences 1 will rotate to a horizontal state. Cooperating with the arched arrangement of the protective fence 1, the inclined protective fence 1 will be neatly arranged and will not interfere with each other. This arrangement not only realizes the protection function when the straightening machine is working, but also can be placed horizontally when not in use, without affecting other work and personnel passing. When working, the horizontal protective fence 1 needs to be rotated to the horizontal state. Only the rotating handle 8 needs to be rotated, so as to rotate the winding roller to wind the connecting belt 10. With the movement of the connecting belt 10, the separating belt 12 will move in the same direction. Part of the separating belt 12 is wound outside the rotating shaft 11. With the movement of the separating belt 12, the rotating shaft 11 will rotate, thereby driving the protective fence 1 to rotate from horizontal to vertical state. The surface of the operation box 4 is provided with a lock catch for fixing the rotating handle 8 in place, preventing the protective fence 1 from falling after being vertically arranged. At the same time, the end of the protective fence 1 is limited in the rotating part of the fixed seat 5 and can only rotate by 90 degrees, preventing the protective fence 1 from rotating excessively. When supplying the straightening machine with steel bars, the head of a coil of steel bars is generally inserted into the straightening machine. With the continuous pulling of the straightening machine, the coil of steel bars will be pulled out until it is empty. However, when a coil of steel bars is wound together, it is easy to entangle with each other, which may cause the whole coil of steel bars to be dragged during the pulling process, causing accidents. Therefore, a worker is generally needed to constantly move the steel bars or observe during the general straightening process. Through the arrangement of the dispersing arm 13, a coil of steel bars is sleeved outside the dispersing arm 13. Then the driving rotating assembly and the vibrating assembly are used to make the dispersing arm 13 rotate in a conical shape with the bottom as the fulcrum. At the same time, the vibrating assembly makes the surface of the dispersing arm 13 vibrate. The rotating dispersing arm 13 will continuously contact the outer edge of the steel bar coil, and the combination between the steel bars will be shaken under the action of vibration, so that the steel bars can be smoothly pulled out by the straightening machine, thereby further protecting the safety of the straightening machine during work. The driving motor drives the transmission rod 20 and the pinion 19 to rotate, thereby driving the gear wheel 24 to rotate. Since the dispersing arm 13 is inserted into the hole of the gear wheel 24, the rotation of the gear wheel 24 can drive the dispersing arm 13 to rotate and swing, thereby realizing the effect that the outer circle of the dispersing arm 13 directly contacts the steel bar coil. The solid ball is limited in the groove by the rotating seat 28, but can rotate, thereby enabling the dispersing arm 13 to swing and limiting the position of the bottom of the dispersing arm 13, so that it will not be thrown out.By clamping the snap ring 25 with the stable frame 15, the gear wheel 24 can only rotate, and the limiting rod 26 extending downward from the gear wheel 24 will push against the solid ball, thereby clamping the solid ball up and down, so that the solid ball and the dispersion arm 13 cannot be pulled out, but can rotate, ensuring the normal working process of the dispersion arm 13; by driving the rotating rope 22 to rotate through the driving assembly, the plurality of impact arms 23 are driven to rotate in the dispersion arm 13, and since the center of gravity of the dispersion arm 13 is moved outward, in the rotating process, the vibration effect is brought to the entire elastic dispersion arm 13, and the vibration effect is transmitted to the steel bar roll, so that the steel bars can be effectively dispersed, and the steel bars can be pulled out neatly, reducing the problem that the entire steel bar roll is dragged, and the entire process also does not need manual participation; when the pinion 19 rotates, the transmission rod 20 will also rotate the transmission rope 21 at the same time, and the rotation will be transmitted to the rotating rope 22 to realize the rotating vibration effect, and through such a setting, it is not necessary to set a power source, and when the gear wheel 24 works, the impact arm 23 can also rotate together; by absorbing the metal iron filings generated in the working process through the air suction machine 7, air pollution is reduced, and the setting of the clamping seat 6 can correspond to the position of the dispersion arm 13, so that the placing seat 3 can also be stored below the protective fence 1, and the movable groove 9 can move the protective rope 2 therein when the protective fence 1 is horizontal, reducing the bending force received by the protective rope 2.

[0046] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application.
