[0026] The application will be described in further detail below with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the application. In addition, it should be noted that only parts related to the application are shown in the drawings for ease of description.

[0027] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and embodiments.

[0028] Referring to Figures 1 to 5 As shown in the drawings, the present application provides a safety protection device for a reinforcing bar straightening machine, comprising: a baffle 1, a roller 2, a support rod 3, and a sliding block 4.

[0029] The two baffles 1 are oppositely arranged. The two baffles 1 are respectively installed on the opposite sides of the reinforcing bar straightening machine 5 through connecting beams 11.

[0030] In the embodiment, the baffle is circular. The two baffles are coaxially arranged. The distance between the two baffles is greater than the width of the reinforcing bar straightening machine. Specifically, the model of the reinforcing bar straightening machine is JT6-12, and the width thereof is 50 cm.

[0031] Among them, three connecting beams are connected to the baffle. The end of the connecting beam away from the baffle is connected with a reinforcing plate. The connecting beam and the reinforcing plate are respectively installed on the side of the reinforcing bar straightening machine through bolts.

[0032] The baffles on both sides of the reinforcing bar straightening machine serve as the hub connection of the reinforcing bar straightening machine and the roller, prevent the reinforcing bar from swinging greatly during the straightening process and after the cutting, and play a safety protection role.

[0033] The roller 2 is rotatably installed between the two baffles 1.

[0034] In the embodiment, the roller 2 is coaxially connected with a rotating shaft 21. The baffle 1 is provided with a shaft hole. The rotating shaft 21 is rotatably arranged in the shaft hole.

[0035] The length of the rotating shaft is 80 cm. The two ends of the rotating shaft extend to the two sides of the reinforcing bar straightening machine by 15 cm. The rotating shaft 21 is arranged in the horizontal direction. In the embodiment, the two ends of the rotating shaft are rotatably arranged in the shaft hole through a force bearing.

[0036] The two ends of the rotating shaft are respectively formed with external threads and screwed with anti-loose nuts. The anti-loose nuts are used to prevent the roller from slipping off the rotating shaft. The length of the roller is 46 cm, and the inner diameter thereof is 46 cm. The roller is made of a steel plate. The thickness of the steel plate is 1 cm, and the roller is rolled into a hollow cylinder. The roller is coaxially arranged with the rotating shaft, and a spoke rod is connected between the rotating shaft and the inner wall of the roller.

[0037] The number of spoke rods is multiple. The multiple spoke rods are arranged at equal intervals along the circumferential direction of the rotating shaft. In this embodiment, the number of spoke rods is four.

[0038] In this embodiment, the number of support rods 3 is multiple. The multiple support rods 3 are connected to the two baffles 1 and arranged at intervals along the circumferential direction of the drum 2.

[0039] The number of sliding blocks 4 is multiple. The multiple sliding blocks 4 are attached to the circumferential surface of the drum 2. The multiple sliding blocks 4 are slidably arranged on the support rods 3. The sliding blocks 4 are provided with through holes. The reinforcing bars 6 are spirally wound on the drum 2. The sliding blocks 4 movably arranged on the multiple support rods 3 are arranged in the through holes.

[0040] As a preferred embodiment, the through hole of the sliding block 4 on one support rod 3 is arranged in the same plane as the inlet, that is, the through hole of the sliding block 4 on one support rod 3 above the drum is in the same horizontal plane as the inlet.

[0041] In this embodiment, the two ends of the support rod 3 are respectively fixed with limit blocks 31. The multiple sliding blocks 4 are arranged between the two limit blocks 31.

[0042] The number of support rods 3 is two. The two support rods 3 are arranged on opposite sides of the drum 2.

[0043] Referring to Figure 3 The sliding block 4 comprises a base 41 and a sleeve ring 42.

[0044] The base 41 is provided with a through hole. The support rod 3 is movably arranged in the through hole. The sleeve ring 42 is connected to the side of the base 41 facing the drum 2. The through hole is formed in the sleeve ring 42.

[0045] Referring to Figure 4 The safety protection device for the reinforcing bar straightening machine further comprises a controller. The sleeve ring 42 is provided with a insertion hole. The base 41 is provided with an electric hydraulic push rod 43 aligned with the insertion hole. The controller is connected to the electric hydraulic push rod 43 and the reinforcing bar straightening machine 5.

[0046] When the reinforcing bar straightening machine 5 cuts the reinforcing bar 6, the controller starts the electric hydraulic push rod 43, and the telescopic end of the electric hydraulic push rod 43 extends into the sleeve ring 42 through the insertion hole and presses against the reinforcing bar 6 to lock the reinforcing bar 6.

[0047] The hole diameter of the through hole of the base of the safety protection device for the reinforcing bar straightening machine is slightly larger than the outer diameter of the support rod. The cross section of the support rod is rectangular, and the shape of the through hole of the corresponding base is adapted to the shape of the cross section of the support rod. The sliding block plays a role in the process of straightening the reinforcing bar. By freely moving the sliding block on the support rod, the large amplitude swing of the reinforcing bar during the straightening process is slowed down, the mechanical energy loss is reduced, and the safety is increased.

[0048] The inner ring hole of the sleeve ring, i.e. the inner diameter of the insertion hole, is 1.8 cm, and the inner diameter of the feeding port of the reinforcing steel bar straightening machine is 1 cm. The sliding block reduces the large swing phenomenon of the reinforcing steel bar during the reinforcing steel bar straightening and cutting process due to the rigidity and ductility of the reinforcing steel bar itself, and is easy to cause injury to the surrounding workers.

[0049] In addition, through the signal linkage of the controller and the reinforcing steel bar straightening machine, when the reinforcing steel bar straightening machine cuts off the reinforcing steel bar, the controller starts the electric hydraulic push rod to lock the cut-off reinforcing steel bar, thereby avoiding the retracting and tail swinging of the reinforcing steel bar.

[0050] During the adjustment of the reinforcing steel bar to be adjusted, the reinforcing steel bar straightening machine is started, and the reinforcing steel bar to be adjusted enters the feeding port of the reinforcing steel bar straightening machine after one round around the roller, thereby avoiding the problem that the reinforcing steel bar cannot be effectively controlled to have too large swing amplitude during the reinforcing steel bar straightening process of the traditional reinforcing steel bar straightening machine. When the reinforcing steel bar is straightened and cut off, the cut-off reinforcing steel bar still remains in the original position due to the limiting effect of the sliding block, the path of the reinforcing steel bar straightening is limited, the large swing phenomenon of the reinforcing steel bar during the reinforcing steel bar straightening and cutting process is effectively avoided, and the safety during the reinforcing steel bar straightening process is greatly improved.

[0051] The safety protection device for the reinforcing steel bar straightening machine can effectively prevent the risks of the reinforcing steel bar hanging in the feeding port of the reinforcing steel bar straightening machine, large swing of the reinforcing steel bar, and mixing of the nearby raw materials together, does not need to assign a person to look after during the straightening process, saves the labor cost, and ensures the safety hidden danger of the person looking after.

[0052] The above description is only the preferred embodiments of the present application and the explanation of the applied technical principles. It should be understood by those skilled in the art that the scope of the application involved in the present application is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the technical solutions formed by mutually replacing the above features and the technical features disclosed in the present application (but not limited to) having similar functions.
