Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of steel bars, and in particular, to a high-strength corrosion-resistant steel bar. BACKGROUND

[0002] In many fields of modern industrial production, such as construction, machinery manufacturing, aerospace, etc., steel bars play a crucial role. Among them, high-strength corrosion-resistant steel bars, due to their excellent performance, have become the core material of many key engineering and equipment. However, in the transportation link of steel bars, there are some problems that need to be solved urgently, which seriously affect the quality and use effect of steel bars.

[0003] During transportation, steel bars are extremely vulnerable to corrosion. On the one hand, the transportation environment is complex and changeable, and moisture, oxygen, and industrial pollutants in the air can all react with the surface of the steel bar, causing rust and corrosion. This phenomenon is more pronounced in humid coastal areas or areas with serious industrial pollution. For example, in some port transportation, steel bars are exposed to high humidity and salt-containing air for a long time, and surface rust spots may appear in a short time, which not only affects the appearance of the steel bar, but also reduces its strength and corrosion resistance, greatly reducing the reliability of the steel bar in subsequent use.

[0004] On the other hand, the current transportation method cannot guarantee the stability of steel bar transportation. Steel bars are usually large in size and heavy in weight, and are prone to displacement and collision during transportation due to vehicle bumps and vibrations. The existing transportation fixing device is often imperfect and cannot effectively constrain the movement of the steel bar. For example, during long-distance freight transportation, the vehicle frequently brakes, accelerates, and vibrates when passing through uneven road surfaces, which may cause the steel bars to collide and scratch each other. Such collisions not only cause damage to the surface of the steel bar and damage its corrosion-resistant coating, further exacerbating corrosion, but also may cause deformation of the steel bar, affecting its dimensional accuracy and shape tolerance, reducing the quality of the steel bar, and increasing the difficulty of subsequent processing and use.

[0005] With the rapid development of industry, the demand for high-strength corrosion-resistant steel bars is increasing, and the quality requirements are also becoming higher and higher. Therefore, it is urgent to solve the corrosion and unstable transportation problems of steel bars during transportation, which has important practical significance for ensuring the quality of steel bars, improving production efficiency, and reducing production costs. SUMMARY

[0006] To overcome the above-mentioned defects, embodiments of the present disclosure provide a high-strength corrosion-resistant steel bar, which solves the technical problem that the existing transportation fixing device in the prior art is often imperfect and cannot effectively constrain the movement of the steel bar, and the collision not only causes damage to the surface of the steel bar and damages its corrosion-resistant coating, further exacerbating corrosion.

[0007] According to one aspect, at least one embodiment of this disclosure provides a high-strength corrosion-resistant steel bar, comprising:

[0008] A support frame and a steel rod body, wherein the steel rod body is mounted on the support frame;

[0009] A protective component is disposed on the exterior of the steel bar body;

[0010] The anti-corrosion spraying equipment and the conveying spraying assembly are provided, wherein the anti-corrosion spraying equipment is mounted on one side of the support, and the conveying spraying assembly is mounted on the support.

[0011] The protective component includes an outer frame, which is fitted onto the outside of the steel bar body. The outer frame has raised layers on all four opposite surfaces, which are attached to the surface of the steel bar body. The two ends of the outer frame are a sealed structure and an open structure, respectively. The open end of the outer frame has several notches, and a stop block is rotatably connected to the notch by a pin.

[0012] As a further technical solution, the conveying and spraying assembly includes an annular pipe, which is fixed inside the support. Several nozzles are provided on the surface of the annular pipe, and the annular pipe is connected to the output end of the anti-corrosion spraying equipment.

[0013] As a further technical solution, the bracket is provided with several support wheels inside. The support wheel located at the center of the bracket is rotated by a motor. Telescopic cylinders are provided on both sides of the bracket, and clamps are provided at the output end of the telescopic cylinders.

[0014] As a further technical solution, the bracket has several openings on one side, and a pair of second cylinders are provided on one side of the bracket. A crossbeam is provided at the output end of the second cylinders, and a pair of conveying rollers are rotatably connected to the side surface of the crossbeam. The conveying rollers pass through the openings and are located inside the bracket.

[0015] As a further technical solution, the conveying roller is supported at the bottom of the outer frame.

[0016] As a further technical solution, the surface of the support wheel is a concave structure surface.

[0017] As a further technical solution, all four surfaces of the outer frame are hollow structures.

[0018] As a further technical solution, the width of the support wheel is lower than the size of the hollow opening of the outer frame, and the support wheel passes through the hollow opening of the outer frame and is located inside.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. The beneficial effect of the protective component in this disclosure is that it effectively solves the problems of unstable transport and easy corrosion of steel bars. The outer frame is fitted onto the outside of the steel bar body. Its internal protrusions not only buffer vibrations during transportation but also position the steel bar body, preventing it from shaking and colliding. The sealing and opening structure of the outer frame is reasonably designed. The stop block at the opening end can close the opening after the steel bar body is inserted, preventing foreign objects from entering and the steel bar from slipping out. Moreover, the outer frame can protect the anti-corrosion coating on the surface of the steel bar body, reducing coating damage caused by collisions and friction, and lowering the risk of corrosion. The hollow structure reduces the weight of the outer frame without affecting the protective performance, facilitating the stacking and transportation of steel bars.

[0021] 2. The beneficial effects of the conveying and spraying assembly in this disclosure are that it greatly improves the production efficiency and corrosion resistance of the steel bars. The annular pipe and nozzle, in conjunction with the anti-corrosion spraying equipment, can evenly spray the anti-corrosion material onto the steel bar body, ensuring the steel bar has good corrosion resistance. The support wheels, driven by a motor, rotate the steel bar body, making the anti-corrosion material spraying more uniform. The telescopic cylinder and clamping plate ensure the stability of the steel bar body during spraying. The second cylinder, crossbeam, and conveying roller work together to accurately deliver the sprayed steel bar body into the outer frame. Furthermore, the concave structure of the support wheels keeps the steel bar body centered, preventing skewing and improving the accuracy and reliability of the entire production and transportation process.

[0034] As shown in Figures 1-4 , which shows a high-strength corrosion-resistant steel bar in an embodiment of the present disclosure, comprising:

[0035] A support 1 and a steel bar body 2 provided on the support 1;

[0036] A protection assembly 4 provided outside the steel bar body 2;

[0037] A corrosion-resistant spraying device 3 provided on one side of the support 1 and a conveying and spraying assembly 5 provided on the support 1;

[0038] The protection assembly 4 comprises an outer frame 4-1 sleeved outside the steel bar body 2, and a convex layer 4-2 is arranged on the opposite four surfaces in the outer frame 4-1, the convex layer 4-2 is attached to the surface of the steel bar body 2, and the two ends of the outer frame 4-1 are respectively closed and open structure, a plurality of notches 4-3 are formed in the open end of the outer frame 4-1, and a stop block 4-4 is rotatably connected in the notch 4-3 through a pin shaft.

[0039] In some examples, in order to provide effective protection for the steel bar body 2 during transportation and use of the high-strength corrosion-resistant steel bar, a protection assembly 4 is designed, which includes an outer frame 4-1 sleeved outside the steel bar body 2, and a convex layer 4-2 arranged on the opposite four surfaces in the outer frame 4-1 can closely fit on the surface of the steel bar body 2, playing a positioning and buffering role, avoiding damage to the steel bar body 2 due to shaking during transportation, and the two ends of the outer frame 4-1 are respectively provided with a closed structure and an open structure, a plurality of notches 4-3 are formed in the open end, and a plurality of stop blocks 4-4 are rotatably connected in the notches 4-3 by a pin shaft, after the steel bar body 2 is loaded into the outer frame 4-1, the stop blocks 4-4 can be rotated to a closed state to close the open end, prevent external debris from entering the inside of the outer frame 4-1, and also avoid the steel bar body 2 from sliding out of the open end. In this way, the protection assembly 4 forms a protective shell outside the steel bar body 2, which not only effectively protects the steel bar body 2 during transportation, but also avoids the corrosion-resistant layer on the surface of the steel bar body 2 from being damaged due to collision, friction and other reasons, greatly improving the protection performance and transportation convenience of the steel bar body 2.

[0040] Through the cooperative work of the outer frame 4-1, the convex layer 4-2, the notches 4-3, the pin shaft and the stop blocks 4-4, the protection assembly 4 realizes the functions of forming a protective shell outside the steel bar body 2, facilitating transportation and protecting the corrosion-resistant layer.

[0041] As shown in Figures 1-4 The conveying and spraying assembly 5 includes an annular pipeline 5-1 fixed inside the support 1, a plurality of nozzles 5-2 are arranged on the surface of the annular pipeline 5-1, the annular pipeline 5-1 is connected with the output end of the anti-corrosion spraying equipment 3, a plurality of supporting wheels 5-3 are arranged inside the support 1, the supporting wheels 5-3 located at the center of the support 1 are controlled to rotate by a motor, a telescopic cylinder 5-4 is arranged on both sides of the support 1, a clamping plate 5-5 is arranged at the output end of the telescopic cylinder 5-4, a plurality of through openings 5-6 are formed in one side of the support 1, a pair of second cylinders 5-7 are arranged on one side of the support 1, a horizontal frame 5-8 is arranged at the output end of the second cylinders 5-7, a pair of conveying rollers 5-9 are rotatably connected to the side surface of the horizontal frame 5-8, and the conveying rollers 5-9 pass through the through openings 5-6 and are located inside the support 1.

[0042] In some examples, in the production process of high-strength corrosion-resistant steel rod, in order to spray corrosion-resistant material on the surface of the steel rod body 2 and accurately push it into the outer frame 4-1, a conveying and spraying assembly 5 is designed, which comprises an annular pipe 5-1 fixed inside the support 1, a plurality of nozzles 5-2 arranged on the surface of the annular pipe 5-1 can uniformly spray corrosion-resistant material on the surface of the steel rod body 2, the annular pipe 5-1 is connected with the output end of the corrosion-resistant spraying equipment 3, and the corrosion-resistant material can be continuously and stably supplied to the nozzles 5-2. A plurality of supporting wheels 5-3 are arranged inside the support 1, the supporting wheel 5-3 located at the center of the support 1 is controlled to rotate by a motor, which can drive the steel rod body 2 to rotate, so that the corrosion-resistant material is uniformly sprayed on the entire outer surface of the steel rod body 2, the telescopic cylinders 5-4 arranged on both sides of the support 1, the clamping plates 5-5 at the output ends of the telescopic cylinders 5-4 can clamp and fix the steel rod body 2 during spraying, to ensure the stability of the steel rod body 2 during spraying. A plurality of through openings 5-6 are formed in one side of the support 1, a pair of second cylinders 5-7 are arranged on one side of the support 1, the cross frames 5-8 at the output ends of the second cylinders 5-7 can control the height through telescopic control, and a pair of conveying rollers 5-9 rotatably connected to the side surfaces of the cross frames 5-8 are used to support the outer frame 4-1. When the steel rod body 2 is completed corrosion-resistant spraying, the second cylinders 5-7 push the cross frames 5-8, so that the conveying rollers 5-9 pass through the through openings 5-6 and enter the inside of the support 1, and the steel rod body 2 sprayed with corrosion-resistant material is pushed into the outer frame 4-1, to complete the conveying and assembling process of the steel rod body 2. After assembly is completed, the supporting wheels 5-3 can convey the outer frame 4-1 and the steel rod body 2 to a certain height and then convey them outward.

[0043] Through the cooperation of the annular pipe 5-1, the nozzles 5-2, the supporting wheels 5-3, the motor, the telescopic cylinders 5-4, the clamping plates 5-5, the through openings 5-6, the second cylinders 5-7, the cross frames 5-8 and the conveying rollers 5-9, the conveying and spraying assembly 5 realizes the function of spraying corrosion-resistant material on the surface of the steel rod body 2 and pushing it into the outer frame 4-1, to ensure that the steel rod body 2 has good corrosion-resistant performance.

[0044] For example, as shown in Figure 3 The conveying rollers 5-9 are supported at the bottom of the outer frame 4-1.

[0045] In some examples, through the lifting conveying rollers 5-9, the outer frame 4-1 can be supported to move while the height can be adjusted, and the steel rod body 2 can be entered.

[0046] For example, as shown in Figure 3 The surface of the supporting wheel 5-3 is a concave structure surface.

[0047] In some examples, through the concave structure surface, the steel rod body 2 can be kept in the central position on the supporting wheel 5-3 and will not be skewed.

[0048] For example, as shown in Figure 1 The outer frame 4-1 has a hollow structure on all four surfaces.

[0049] In some examples, the hollow structure reduces the overall weight of the outer frame 4-1 without affecting the protection, and the square structure of the outer frame 4-1 allows the steel bar body 2 to be better arranged and stacked.

[0050] For example, as shown in Figure 3 The support wheel 5-3 is located inside the outer frame 4-1 through the hollow opening of the outer frame 4-1, and the width of the support wheel 5-3 is lower than the size of the hollow opening of the outer frame 4-1.

[0051] In some examples, the support wheel 5-3 can pass through the outer frame 4-1 to facilitate the support and conveying state of the steel bar body 2.

[0052] In actual use: the outer frame 4-1 is placed on the support 1, the telescopic cylinder 5-4 drives the clamping plate 5-5 to clamp the outer frame 4-1, the steel bar body 2 is placed at the other end of the support 1, and is supported at the bottom by the support wheel 5-3, the support wheel 5-3 located at the center of the support 1 rotates under the control of the motor, driving the steel bar body 2 to rotate, the corrosion-resistant spraying device 3 uniformly sprays the corrosion-resistant material on the surface of the steel bar body 2 through the annular pipeline 5-1 and the nozzle 5-2, and the spraying process enters the outer frame 4-1, after the spraying is completed, the stop block 4-4 is rotated to close the open end of the outer frame 4-1, the second cylinder 5-7 pushes the cross frame 5-8, so that the conveying roller 5-9 rises to support the outer frame 4-1, and the bottom of the outer frame 4-1 is separated from the support wheel 5-3, and finally the support wheel 5-3 lifts the outer frame 4-1 containing the steel bar body 2 and conveys it outward.

[0053] It should be noted that the above examples are only used to illustrate the technical solutions of the present disclosure and are not limiting. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, and all should be covered in the scope of the claims of the present disclosure.
