Description

Technical Field

[0001] This utility model relates to the field of steel strand winding and unwinding technology, specifically a steel strand anti-explosion device. Background Technology

[0002] Steel strand winding and unwinding refers to the process of winding steel strand onto a winding drum and releasing it from the drum. Steel strand is a steel product made of multiple steel wires twisted together, and it is often used in infrastructure construction, such as highways, high-speed railways, bridges, and dams.

[0003] For example, the Chinese authorized patent (steel strand release device) with announcement number CN222099204U includes a support mechanism and a suspension mechanism. The support mechanism includes a connected support structure and a locking structure. The support structure supports the steel strand reel, and the locking structure can abut and fix against the inner wall of the steel strand reel. The suspension mechanism includes a suspension bracket and a suspension assembly. The suspension bracket is fixed on the base surface, one end of the suspension assembly is connected to the suspension bracket, and the other end of the suspension assembly is detachably connected to the support mechanism. The suspension assembly can rotate horizontally relative to the suspension bracket, which facilitates the release and extraction of the steel strand. Compared with the prior art method of pulling the steel strand outward from the end on the inner wall of the steel strand reel, it can reduce the traction force required to extract the steel strand, which not only improves the protection of the steel strand, but also prevents the steel strand from deforming when it is extracted, eliminating the need for subsequent adjustments and improving the release efficiency of the steel strand.

[0004] However, existing steel strands lack external protection during winding and unwinding, making them prone to breakage during this process. This results in poor stability, requires rewinding, is time-consuming and labor-intensive, and is also complex in structure, costly, and inconvenient to install and maintain. Therefore, it does not meet the current needs. To address this, we have proposed a steel strand anti-breakage device. Utility Model Content

[0005] The purpose of this utility model is to provide a steel strand anti-explosion device to solve the problems mentioned in the background art, such as the lack of external protection when winding and unwinding existing steel strands, which easily leads to wire breakage during winding and unwinding, resulting in poor stability, the need for re-sorting, which is time-consuming and labor-intensive, and the complex structure, high investment cost, and inconvenient installation and maintenance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel strand anti-explosion device, comprising: a first frame, a second frame disposed behind the first frame, a stop bar disposed between the ends of the first frame and the second frame, and multiple stop bars disposed thereon, with connecting parts disposed on the outside of both ends of the stop bar, and the two ends of the stop bar being fixed to the first frame and the second frame respectively through the connecting parts.

[0007] Preferably, both the first frame and the second frame include a first scaffold tube, a second scaffold tube, a third scaffold tube, and a fourth scaffold tube, with one end of the second scaffold tube welded to one side surface of the first scaffold tube, one end of the third scaffold tube welded to one side surface of the second scaffold tube, one end of the fourth scaffold tube welded to one side surface of the third scaffold tube, and one end of the first scaffold tube welded to one side surface of the fourth scaffold tube.

[0008] Preferably, a guide tube is provided at the front of the first frame, and connecting steel bars are welded to the outer surface of the guide tube. Multiple connecting steel bars are provided, and the other ends of the multiple connecting steel bars are welded and fixed to the connection points of the first scaffold tube, the second scaffold tube, the third scaffold tube and the fourth scaffold tube respectively.

[0009] Preferably, the connector includes a stabilizing sleeve, one end of which is provided with an extension plate, and the other end of which is rotatably connected to a first fixing sleeve. A first threaded post is provided on one side of the extension plate, and the first threaded post passes through the first fixing sleeve and is fixed by a threaded nut.

[0010] Preferably, the connector further includes a second fixing sleeve, which is rotatably connected to one side of the stabilizing sleeve. The other side of the stabilizing sleeve is provided with a second threaded post, which passes through the second fixing sleeve and is then threadedly connected to a nut for fixation.

[0011] Preferably, the first frame, the second frame, and the stop bar are all made of round steel pipes.

[0012] Preferably, the guide tube is hollow inside and extends through the front and back.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model is formed by welding one end of the second scaffold pipe to one side surface of the first scaffold pipe, one end of the third scaffold pipe to one side surface of the second scaffold pipe, one end of the fourth scaffold pipe to one side surface of the third scaffold pipe, and one end of the first scaffold pipe to one side surface of the fourth scaffold pipe. The first frame and the second frame are formed by welding them in sequence. The first scaffold pipe, the second scaffold pipe, the third scaffold pipe and the fourth scaffold pipe of the first frame and the second frame are connected by connecting rods, so as to realize the connection between the first frame and the second frame. It has the effect of using local materials, the overall structure is simple and convenient, easy to disassemble and install, and also reduces the investment cost. The rods prevent the steel strand from bursting, improve stability, and solve the problem that when the existing steel strand is wound and unwound, there is no external protection, and the wire is prone to bursting during winding and unwound, resulting in poor stability. It also requires re-sorting, which is time-consuming and laborious, and the structure is complex, the investment cost is high, and it is inconvenient to install and maintain.

[0015] (2) By setting a guide tube in front of the first frame and fixing the guide tube to the first frame through connecting steel bars, the guide tube is connected to the first frame, and one end of the steel strand passes through the guide tube, thereby improving the stability and orientation of the movement of the steel strand.
