Description

Technical Field

[0001] The utility model relates to the field of breaking devices, in particular to a steel bar breaking device with a safety structure. Background Art

[0002] Steel bars refer to steel used for reinforced concrete and prestressed reinforced concrete, and their cross-sections are circular, and sometimes square with rounded corners. In the prior art, a Chinese utility model patent with a public document number of CN216096150U discloses a steel bar breaking device for construction sites. The utility model uses a positioning mechanism to effectively fix the steel bars during the breaking process, avoiding the phenomenon that the workers are injured by manual support and fixation when the steel bars are broken in the traditional way due to the limited manual strength and the elasticity of the steel bars at the moment of breaking.

[0003] However, the utility model fixes the steel bar by squeezing the upper fixed block. During the process of the gate knife breaking the steel bar, the two broken sections of the steel bar are likely to obtain greater kinetic energy, causing the broken steel bar to bounce to the side. The upper fixed block may be impacted and move the compression spring upward, causing the steel bar to break away from the upper fixed block and bounce to the side, causing a safety accident. At the same time, after the upper fixed block is impacted upward by the steel bar, it is easy to accelerate damage. Therefore, when fixing the steel bar in the breaking process, it is not enough to consider limiting the workpiece from moving, but also necessary to consider consuming the kinetic energy obtained by the broken steel bar, so as to make the steel bar breaking process safer.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

One side of the fixing frame 604 is placed on the plate body between the No. 1 mounting plate 601, so that the fixing frame 604 can be kept parallel, and the steel workpiece 5 is inserted into the V-groove 605 of the fixing frame 604. The bolt 608 is screwed downward to move the arc-shaped fixing block 609 downward. The arc-shaped fixing block 609 clamps the steel workpiece 5, making it easy to clamp and fix the steel workpiece 5. When the steel workpiece 5 needs to be disassembled, the bolt 608 can be rotated in the opposite direction.

[0022] like Figure 1 and Figure 4As shown, the screw rod 612 is fixedly connected to one end of the rotating rod 602, the screw rod 612 is movably installed with the limiting plate 613, the counterweight block 617 is fixedly connected with the screw rod 612, the insurance component 6 also includes an arc groove 614, a No. 1 connecting plate 615 and a No. 2 connecting plate 616, the arc groove 614 is opened on the limiting plate 613, the screw rod 612 is movably installed in the arc groove 614, the lower position of the limiting plate 613 is fixedly connected with the No. 1 connecting plate 615 and the No. 2 connecting plate 616, and the limiting plate 613 is fixedly connected to the bottom plate 1 through the No. 1 connecting plate 615 and the No. 2 connecting plate 616, the insurance component 6 also includes a fixing nut 618, and a through hole is opened at the center of the counterweight block 617, and the counterweight block 617 is inserted through the through hole. The screw rod 612 is mounted on the counterweight 617, and the counterweight 617 is fixedly connected to the screw rod 612 by a fixing nut 618. When the steel workpiece 5 is broken into two sections, the fixing frame 604 rotates synchronously with the rotating rod 602, so that the fixing frame 604 and the steel workpiece 5 remain fixedly connected and are not easily separated from each other. The screw rod 612 moves in the arc groove 614 of the limiting plate 613. The length of the arc groove 614 is limited, so that the turning range of the steel workpiece 5 is determined. When the staff is outside this range, safety can be guaranteed. The counterweight 617 moves synchronously with the screw rod 612, which is convenient for consuming the kinetic energy obtained by the steel workpiece 5, reducing the impact force of the steel workpiece 5, reducing the impact force received by the fixing frame 604, and the fixing frame 604 is not easily damaged, thereby extending the service life.

[0023] It should be noted that the utility model is a steel bar breaking device with a safety structure. During the breaking process of the existing steel bar workpiece 5, due to the elasticity of the steel bar, the broken steel bar is easy to obtain greater kinetic energy, thereby ejecting to the side and injuring the staff. Through the safety component 6, the two ends of the steel bar workpiece 5 pass through the fixing frames 604 on both sides, the bolts 608 are screwed downward, the rotating block 611 rotates in the connecting sleeve 610, and pushes the connecting sleeve 610 and the arc-shaped fixing block 609 to move downward, and the two sides of the arc-shaped fixing block 609 move downward synchronously in the slide groove 606. The arc-shaped fixing block 609 clamps and fixes the steel bar workpiece 5 in the V-shaped groove 605, and the bolts 608 are rotated in the opposite direction so that the steel bar workpiece 5 can be disassembled. The cylinder 3 moves the breaking knife 4 downward to break the steel bar workpiece 5. The two broken sections of the steel bar workpiece 5 are flipped to the side, and the fixing frame 604 is synchronously rotated on the No. 1 mounting plate 601 through the rotating rod 602, so that the steel bar workpiece 5 and the fixing frame 604 are kept fixedly connected, and the broken The steel workpiece 5 will not be completely separated or bounced off. When the rotating rod 602 rotates, the screw 612 moves synchronously in the arc groove 614 of the limiting plate 613. The length of the arc groove 614 is limited, so that the turning angle of the fixed frame 604 and the steel workpiece 5 is limited, thereby limiting the range of motion of the steel workpiece 5. The staff is outside this range of motion to ensure safety. The counterweight block 617 is fixedly connected to the screw rod 612. As the screw rod 612 rotates upward, the counterweight block 617 rotates upward synchronously. The counterweight block 617 is made of heavier materials, such as steel, so that when the counterweight block 617 rotates upward, it needs to consume a large amount of kinetic energy, thereby consuming the kinetic energy obtained when the steel workpiece 5 breaks, so that the steel workpiece 5 loses the power to eject outward and reduces the impact force of the steel workpiece 5 on the fixed frame 604, so that the fixed frame 604 is easy to maintain its service life. After the kinetic energy of the fixed frame 604 flipping outward is partially consumed by the counterweight block 617, the fixed frame 604 is easy to fall back naturally.

It is only a preferred embodiment of the utility model, and its description is more specific and detailed, but it cannot be understood as limiting the scope of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The embodiments can be changed, modified, replaced and deformed without departing from the principle and purpose of the utility model.
