Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically to a steel bar threading support structure with pulleys. Background Technology
[0002] Rebar threading support structures are auxiliary devices specifically designed for rebar threading operations. They play a crucial role in the construction engineering field, particularly in the reinforcement of reinforced concrete structures and the connection of rebars. Rebar threading refers to the process of machining the ends of rebars into a specific thread shape, and then screwing the threaded portions of two rebars together to connect them into a single unit. Rebar threading support structures are devices used to support and fix the rebars, maintaining their stability and accuracy during the threading process.
[0003] The rebar needs to be pulled back and forth during the threading process. A large-diameter rebar weighs about tens of kilograms. It is time-consuming and laborious for workers to pull it. Therefore, a rebar threading support structure with pulleys is proposed to solve the problems mentioned above. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a rebar threading support structure with pulleys, which has the advantages of improving rebar threading efficiency and reducing working time. It solves the problem that rebars need to be pulled back and forth during the threading process, and a large-diameter rebar weighs about tens of kilograms, which is both time-consuming and laborious for workers.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rebar threading support structure with pulleys, comprising multiple rebar threading brackets, wherein four sets of pulleys are rotatably sleeved on the upper side of each rebar threading bracket, and four limiting components are provided on the upper side of each rebar threading bracket.
[0006] The limiting assembly includes a threaded rod rotatably sleeved on the left side of the rebar threading bracket, two threaded plates threadedly connected to the outside of the threaded rod, a limiting plate fixedly connected to one side of the two threaded plates opposite to each other, a moving plate fixedly connected to the side of the limiting plate away from the threaded plates, and an internal sliding rod slidably sleeved on the lower side of the moving plate.
[0007] Furthermore, two spacing adjustment components are provided on the outer side of the rebar threading bracket. The spacing adjustment components include a first pipe clamp slidably sleeved on the outer side of the rebar threading bracket, a first positioning bolt threaded to one end of the first pipe clamp, a second pipe clamp fixedly connected to the right side of the first pipe clamp, a second positioning bolt threaded to the upper side of the second pipe clamp, and an inner limiting tube sleeved on the second pipe clamp.
[0008] Furthermore, a movable component is provided on the lower side of the rebar threading bracket. The movable component includes four steel wheels bolted to the lower side of the rebar threading bracket and brake pads mounted on the upper side of the steel wheels.
[0009] Furthermore, the four sets of pulleys are arranged in groups of five, and each group of pulleys is arranged equidistantly in the lateral direction.
[0010] Furthermore, the end of the pulley is rotatably sleeved on the upper side of the rebar threading bracket, and the four rebar threading brackets are arranged horizontally.
[0011] Furthermore, one end of the slide rod is fixed to the upper right side of the rebar threading bracket, and the threaded rod is a bidirectional threaded rod.
[0012] Furthermore, the threaded plate and the movable plate are arranged laterally, and the limiting plate is positioned on the upper side of the pulley for movement.
[0013] Furthermore, a throttle is fixedly fitted onto one end of the threaded rod.
[0014] Compared with the prior art, this utility model provides a steel bar threading support structure with pulleys, which has the following beneficial effects:
[0015] 1. This rebar threading support structure with pulleys allows the rebar to move quickly back and forth on the rebar threading bracket by placing it on the pulley, reducing the force applied by the worker when moving the rebar and improving threading efficiency.
[0016] 2. This pulley-equipped rebar threading support structure uses the rotation of the threaded rod to drive the two threaded plates opposite each other to move closer together and abut against the side of the rebar. When the rebar moves on the upper side of the pulley, it acts as a limiter, preventing the rebar from deviating during back-and-forth movement. This solves the problem that the rebar needs to be pulled back and forth during the threading process, and a large-diameter rebar weighs about tens of kilograms, which is both time-consuming and laborious for workers.

Detailed Implementation
[0022] 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.
[0023] Example 1:
[0024] Please see Figures 1 to 4 This embodiment of a rebar threading support structure with pulleys includes multiple rebar threading brackets 1. Four sets of pulleys 6 are rotatably mounted on the upper side of each rebar threading bracket 1, and four limiting components 5 are provided on the upper side of each rebar threading bracket 1. Each limiting component 5 includes a threaded rod 12 rotatably mounted on the left side of the rebar threading bracket 1, two threaded plates 13 threadedly connected to the outside of the threaded rod 12, a limiting plate 14 fixedly connected to one side of the two threaded plates 13 opposite to each other, a moving plate 15 fixedly connected to the side of the limiting plate 14 away from the threaded plates 13, and an inner sliding rod 16 slidably mounted on the lower side of the moving plate 15.
[0025] The rebar threading bracket 1 has a movable component on its lower side. The movable component includes four steel wheels 2 bolted to the lower side of the rebar threading bracket 1 and brake pads 3 mounted on the upper side of the steel wheels 2. The four sets of pulleys 6 are arranged in groups of five, and each set of pulleys 6 is arranged equidistantly in the transverse direction. The ends of the pulleys 6 are rotatably sleeved on the upper side of the rebar threading bracket 1. The four rebar threading brackets 1 are arranged in the transverse direction. One end of the sliding rod 16 is fixed to the upper right side of the rebar threading bracket 1. The threaded rod 12 is a bidirectional threaded rod. The threaded plate 13 and the movable plate 15 are arranged in the transverse direction. The limiting plate 14 is located on the upper side of the pulleys 6 and moves. One end of the threaded rod 12 is fixedly sleeved with a throttle handle.
[0026] Example 2:
[0027] Please see Figure 1 and Figure 3Based on Embodiment 1, two spacing adjustment components 4 are provided on the outer side of the rebar threading bracket 1. The spacing adjustment component 4 includes a first pipe clamp 8 slidably sleeved on the outer side of the rebar threading bracket 1, a first positioning bolt 9 threadedly connected to one end of the first pipe clamp 8, a second pipe clamp 10 fixedly connected to the right side of the first pipe clamp 8, a second positioning bolt 11 threadedly connected to the upper side of the second pipe clamp 10, and a limiting tube 7 sleeved inside the second pipe clamp 10.
[0028] By adopting the above technical solution, after multiple rebar threading supports 1 are arranged horizontally, the first pipe clamp 8 is sleeved on the outside of the rebar threading support 1 and fixed by the first positioning bolt 9. Then, the limiting pipe 7 is taken out and inserted into the second pipe clamp 10 on one side of the first pipe clamp 8, and then tightened by the second positioning bolt 11. This achieves the fixing of the spacing of multiple rebar threading supports 1, and also allows the second positioning bolt 11 to be loosened so that the spacing of multiple rebar threading supports 1 can be adjusted under the action of the limiting pipe 7.
[0029] The working principle of the above embodiments is as follows:
[0030] The rebar threading bracket 1 can be quickly moved to a designated position via the steel wheel 2. Stepping on the brake pad 3 can stop the steel wheel 2 and prevent the rebar threading bracket 1 from moving. The rebar is placed on the pulley 6, and the rebar is quickly moved for threading by the rotation of the pulley 6 itself, reducing the pushing force applied to the rebar by the worker. To prevent the rebar from swaying left and right when moving, the threaded rod 12 drives the limiting plates 14 on the upper side of the two threaded plates 13 to move closer to each other and abut against the side surface of the rebar. The rebar threading bracket 1 is equipped with four sets of pulleys 6 on the upper side, which can simultaneously support the threading of four different types of rebars. With the corresponding limiting components 5, it can complete the independent limiting purpose.
[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
