Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, specifically a hoisting device for coiled steel bars. Background Technology

[0002] Steel products are generally divided into plates, sections, and wires. Coiled rebar is considered a type of wire rod. As the name suggests, coiled rebar is rebar that is coiled together like wire rod. Its bundling method is the same as that of ordinary wire rod, but it needs to be straightened before use.

[0003] Currently, the hoisting and transportation of coiled steel bars involves first binding and securing the coiled steel bars with straps before hoisting and transportation. However, due to the large weight of the coiled steel bars themselves, friction between the straps and the steel bars during hoisting and transportation can easily cause the straps to break. Loose coiled steel bars during hoisting and transportation pose a safety hazard. Therefore, a hoisting device for coiled steel bars is needed to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this utility model is to provide a coiled steel bar hoisting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coiled rebar hoisting device, comprising a first end plate, a second end plate on one side of the first end plate, an external pressure mechanism on one side of the first end plate, and an internal support mechanism on the side of the second end plate opposite to the first end plate. The external pressure mechanism includes an external pressure arm that presses against the outer side of the coiled rebar, and the internal support mechanism includes an internal support arm that supports the inner side of the coiled rebar. An internal support guide groove is provided on one end face of both the first end plate and the second end plate, and an external pressure guide groove is also provided on one end face of both the first end plate and the second end plate. The external pressure arm is slidably connected in the external pressure guide groove, and the internal support arm is slidably connected in the internal support guide groove. A binding and threading groove is provided on the upper end face of the external pressure arm.

[0006] Preferably, an external pressure slide is fixed to one side surface of the first end plate and the second end plate facing away from each other, and an adjustable slider is fixed to one end of the external pressure support arm and the inner support arm. The adjustable slider is slidably connected in the external pressure guide groove.

[0007] Preferably, an adjusting guide rod is vertically fixed at the center of the upper end face of the adjusting slider, and a return spring is sleeved on the part of the adjusting guide rod located between the adjusting slider and the external pressure slide.

[0008] Preferably, one end of the return spring is fixed to the upper end face of the adjustable slider, and the other end of the return spring is fixed to the lower end face of the external pressure slide.

[0009] Preferably, a positioning slide is fixed on one side surface opposite to the first end plate and the second end plate, and a positioning rod is fixed at one end of the upper surface of the outer pressure arm and the inner support arm, and the positioning rod is properly matched with the positioning slide.

[0010] Preferably, the upper part of the side surface of the first end plate and the second end plate are fixed with lifting hooks, and the lower part of the side surface of the first end plate and the second end plate are fixed with lifting legs.

[0011] This utility model provides a device for hoisting coiled steel bars, which has the following advantages compared with the prior art:

[0012] With the addition of an external pressure mechanism and an internal support mechanism, the internal support arm resets under the return force of the return spring and adaptively supports the inside of the coiled steel bar coil. Meanwhile, the two external pressure arms press against the outside of the coiled steel bar coil under the elastic force of the return spring. In this way, the internal support arms and external pressure arms work together to restrict the coiled steel bar coil from both the inside and outside, thereby achieving the safety function of preventing the coiled steel bar coil from detaching and locking during hoisting. Furthermore, the external pressure arms and internal support arms adaptively adjust their tightness through the elastic force of the return spring, allowing the external pressure mechanism and internal support mechanism to adapt to different application environments for preventing the coiled steel bar coils of different specifications from detaching and locking.

[0013] The first end plate, outer pressure arm, inner support arm, and second end plate are designed to facilitate quick assembly and disassembly of the coiled steel bars before hoisting and quick removal after hoisting. In addition, the outer pressure arm is equipped with a hollow binding and threading groove, which can be used to thread ropes to bind the coiled steel bars, thereby reducing the trouble caused by the coiled steel bars becoming loose and difficult to collect and remove during hoisting due to the binding straps wearing off.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a coiled rebar hoisting device, including a first end plate 1, a second end plate 2 on one side of the first end plate 1, an external pressure mechanism 4 on one side of the first end plate 1, and an internal support mechanism 5 on the side of the second end plate 2 opposite to the first end plate 1. The external pressure mechanism 4 includes an external pressure support arm 6 that presses the outer side of the coiled rebar. The two external pressure support arms 6 are pressed against the outer side of the coiled rebar coil under the elastic force of the return spring 9. In this way, the internal support arm 16 and the external pressure support arm 6 cooperate to restrict the coiled rebar coil from the inside and outside. The internal support mechanism 5 includes an internal support arm 16 that supports the inner side of the coiled rebar. An internal support guide groove 12 is opened on one end face of the first end plate 1 and the second end plate 2. An external pressure guide groove 11 is also opened on one end face of the first end plate 1 and the second end plate 2. The external pressure support arm 6 is slidably connected in the external pressure guide groove 11, and the internal support arm 16 is slidably connected in the internal support guide groove 12. A binding and threading groove 14 is opened on the upper end face of the external pressure support arm 6.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that an external pressure slide 10 is fixed on the opposite side surface of the first end plate 1 and the second end plate 2. An adjustable slider 7 is fixed at one end of the external pressure support arm 6 and the inner support arm 16. The adjustable slider 7 is slidably connected in the external pressure guide groove 11. The adjustable slider 7 at one end of the inner support arm 16 overcomes the elastic force of the return spring 9, so that the two inner support arms 16 can shrink the gap so that the coiled steel bar can be rolled in.

[0022] Further as Figure 3As shown, it is worth noting that an adjusting guide rod 8 is vertically fixed at the center of the upper end face of the adjusting slider 7. A return spring 9 is sleeved on the part of the adjusting guide rod 8 between the adjusting slider 7 and the external pressure slide 10. One end of the return spring 9 is fixed at the upper end face of the adjusting slider 7, and the other end of the return spring 9 is fixed at the lower end face of the external pressure slide 10.

[0023] This solution has the following working process: Before use, push the two inner support arms 16 inward so that the adjusting slider 7 at one end of the inner support arm 16 overcomes the elastic force of the return spring 9. In this way, the two inner support arms 16 can reduce the distance between them so that the coiled steel rebar can be inserted. Then, the inner support arms 16 are reset under the action of the return spring 9 and adaptively support the inner side of the coiled steel rebar. When the outer pressure mechanism 4 is assembled into the second end plate 2, the two outer pressure arms 6 are pressed against the outer side of the coiled steel rebar under the action of the return spring 9. In this way, the inner support arms 16 and the outer pressure arms 6 can restrict the coiled steel rebar from the inside and outside, thereby realizing the safety function of preventing the coiled steel rebar from getting off during hoisting. In addition, the outer pressure arms 6 and the inner support arms 16 adaptively adjust the tightness of the fit through the elastic force of the return spring 9, so that the outer pressure mechanism 4 and the inner support mechanism 5 can adapt to the application environment of preventing the coiled steel rebar from getting off during hoisting.

[0024] According to the above working process, the inner support arm 16 is reset under the return force of the return spring 9 and adaptively supports the inner side of the coiled steel bar. The two outer pressure arms 6 are pressed against the outer side of the coiled steel bar under the elastic force of the return spring 9. In this way, the inner support arm 16 and the outer pressure arms 6 can restrict the coiled steel bar from the inside and outside, thereby achieving the safety function of preventing the coiled steel bar from getting off during hoisting. In addition, the outer pressure arms 6 and the inner support arms 16 adaptively adjust the tightness of the fit through the elastic force of the return spring 9, so that the outer pressure mechanism 4 and the inner support mechanism 5 can adapt to the application environment of preventing the coiled steel bar from getting off and locking for different specifications.

[0025] Further as Figure 4As shown, it is worth noting that a positioning slide 15 is fixed to the opposite side surface of the first end plate 1 and the second end plate 2. A positioning rod 13 is fixed to one end of the upper surface of the outer pressure arm 6 and the inner support arm 16. The positioning rod 13 is properly engaged with the positioning slide 15. When the first end plate 1 and the second end plate 2 are assembled, one end of the outer pressure arm 6 is inserted into the outer pressure guide groove 11 of the second end plate 2, and at the same time, the positioning rod 13 on the outer pressure arm 6 is engaged with the positioning slide 15 on the second end plate 2 away from the center. The positioning rod 13 on the inner support arm 16 engages with the positioning slide 15 near the center of the first end plate 1. The flexible assembly and disassembly of the first end plate 1, the outer pressure arm 6, the inner support arm 16, and the second end plate 2 facilitates quick installation before hoisting of the coiled steel rebar and quick removal after hoisting. Furthermore, the outer pressure arm 6 has a hollow binding and threading groove 14 that can be used to thread ropes to bind the coiled steel rebar, thereby reducing the trouble caused by the coiled steel rebar becoming loose and difficult to collect and remove during hoisting due to the binding straps wearing off.

[0026] Further as Figure 1 As shown, it is worth noting that hoisting hooks 17 are fixed to the upper part of the side surface of the first end plate 1 and the second end plate 2, and lifting legs 3 are fixed to the lower part of the side surface of the first end plate 1 and the second end plate 2. The hoisting hooks 17 are used to bind the hoisting rope for hoisting.

[0027] In summary: the inner support arm 16 resets under the restoring force of the return spring 9 and adaptively supports the inner side of the coiled steel bar, while the two outer pressure arms 6 are pressed against the outer side of the coiled steel bar under the elastic force of the return spring 9. This combination of inner support arm 16 and outer pressure arms 6 restricts the coiled steel bar from both the inside and outside, thus achieving the safety function of preventing the coiled steel bar from detaching and locking during hoisting. Furthermore, the outer pressure arms 6 and inner support arms 16 adaptively adjust their tightness through the elastic force of the return spring 9, ensuring... The external pressure mechanism 4 and the internal support mechanism 5 are adapted to the application environment of locking coiled steel bars of different specifications to prevent them from falling off. The flexible assembly and disassembly of the first end plate 1, the external pressure support arm 6, the internal support support arm 16, and the second end plate 2 facilitate the quick installation of the coiled steel bars before hoisting and the quick removal after hoisting. In addition, the external pressure support arm 6 is provided with a hollow binding and threading groove 14, which can be used to thread ropes to bind the coiled steel bars, thereby reducing the trouble of the coiled steel bars becoming loose and difficult to collect and remove during hoisting due to the breaking of the binding strap.
