Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, and particularly relates to a construction device for straightening and pulling steel strands. Background Art

[0002] In the field of steel strand construction, the straightening and pulling process of steel strands is one of the key steps, which is of great significance for ensuring the quality of steel strands and construction efficiency. Although the traditional steel strand unwinding bracket can realize the unwinding function of steel strands, during the straightening and pulling process, due to the certain elasticity and curling property of the steel strands themselves, the phenomenon that the steel strands continue to unwind and wind often occurs during the straightening process. This not only affects the straightening effect of the steel strands but also may lead to potential safety hazards during the construction process.

[0003] In recent years, with the continuous development of construction technology, the requirements for steel strand straightening and pulling devices have become higher and higher. The utility model patent with the publication number CN220744886U proposes a steel strand unwinding bracket provided with a conical protective cage. This device effectively prevents safety accidents caused by the scattering of steel strands during the unwinding process. However, during the straightening and pulling process of steel strands, this device is not specifically designed for the clamping problem of the steel strand moving out part. Therefore, the situation of continuous unwinding and winding may still occur during straightening.

[0004] In view of the above problems, this application proposes a new type of construction device for straightening and pulling steel strands. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a construction device for straightening and pulling steel strands, which can ensure that during the straightening and pulling process of steel strands, the steel strands are effectively fixed and straightened, avoiding poor straightening effect and potential safety hazards caused by continuous unwinding and winding.

[0023] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0024] As Figures 1-5 shown, a construction device for straightening and pulling steel strands includes two square frames 1, which are composed of multiple 16-mm steel bars, and the length and width of the square frame 1 are both 16 cm. Inside both of the two square frames 1, a steel bar ring 2 is fixed, and the diameter of the steel bar ring 2 is 80 cm. When placing the steel strand coil, the steel strand coil can be placed inside the two steel bar rings 2. One side of the two steel bar rings 2 close to each other extends out of the square frame 1 and extends to the outside of the square frame 1. Through this setting, the steel bar ring 2 can install and support the steel strand coil, prevent the steel strand coil from falling, and it can also be supported by a cross beam steel bar or directly placed on the ground and clamped by the two square frames 1. A plurality of adjusting mechanisms are installed between the two square frames 1, and the adjusting mechanisms are used to adjust the distance between the two square frames 1. One side of one steel bar ring 2 away from the other steel bar ring 2 is fixed with a plurality of connecting frames 5, and one end of the plurality of connecting frames 5 away from the steel bar ring 2 is fixed with a clamping ring 6, and the diameter of the clamping ring 6 is 10 cm;

[0025] When paying off the steel strands, the wire end inside the steel strand coil can be passed through one of the steel bar rings 2 and extended into the inside of the clamping ring 6, and the steel strands are paid off through the clamping ring 6, and the steel strands can be straightened and pulled through the clamping ring 6 in the subsequent process. The straightening and pulling of the steel strands can be carried out in a relatively small space, the construction is convenient and fast, time-saving and labor-saving, and with the restriction and protection of the steel bar main body, it is safer to straighten and pull the steel strands, improving the construction efficiency and being easy to operate;

[0026] A clamping mechanism is installed on the clamping ring 6, and the clamping mechanism is used to clamp the steel strands.

[0027] Referring to the appendix Figures 1-2 , each adjusting mechanism includes a mounting block 3 fixed on the two square frames 1, and a first threaded rod 4 is threadedly connected inside the two mounting blocks 3. A nut 14 is threadedly connected to the outside of the first threaded rod 4 and at one end of one mounting block 3 away from the other mounting block 3;

[0028] When placing the steel strand coil, the first threaded rod 4 can be turned, so that the two square frames 1 are separated. At this time, the steel strand coil can be placed between the two square frames 1, and then another square frame 1 is aligned with this square frame 1. The first threaded rod 4 is screwed into the mounting block 3 and fixed by the nut 14 to realize the installation and fixation of the steel strand coil.

[0029] Refer to the appendix Figure 4 , the clamping mechanism includes two second threaded rods 7, and the two second threaded rods 7 are symmetrically threadedly connected inside the clamping ring 6. One end of the two second threaded rods 7 close to each other is rotatably connected with a mounting plate 8, and at least one limiting rod 9 is fixed on the side of each of the two mounting plates 8 away from each other, and the limiting rod 9 is slidably connected with the clamping ring 6;

[0030] A damping component is fixed on the side of the two mounting plates 8 close to each other, and the damping component is used to prevent the steel strand from moving.

[0031] Refer to the appendix Figure 5 As shown, according to the above structure, the damping component includes a plurality of springs 10 fixed on the side of the two mounting plates 8 close to each other, and a clamping plate 11 is fixed at one end of the plurality of springs 10 close to each other;

[0032] When it is necessary to clamp the steel strand, the second threaded rod 7 can be screwed, and through the threaded connection between the second threaded rod 7 and the clamping ring 6, and the restriction of the limiting rod 9, the mounting plate 8 can move in the direction close to the steel strand, and the steel strand is clamped by the clamping plate 11. When the steel strand is pulled, through the distortion and skew of the spring 10, anti-slip grooves 12 are arranged on both sides of the clamping plate 11, and anti-slip protrusions 13 are arranged inside the anti-slip grooves 12. Through this, and then through the anti-slip grooves 12 and anti-slip protrusions 13 arranged in the clamping plate 11, the clamping plate 11 can have a better effect of clamping the steel strand to death. Through the arrangement of the anti-slip grooves 12, the anti-slip grooves 12 can increase the friction on the surface of the clamping plate 11, and through the arrangement of the anti-slip protrusions 13, the friction is further increased.
