Description

Technical Field

[0001] This utility model relates to the field of bridge equipment technology, specifically a welding device for reinforcing bridge steel cables. Background Technology

[0002] Bridge steel cable welding equipment is commonly referred to as welding manipulator or welding equipment in engineering. It is mostly used for welding long seams of large metal structures and is suitable for processes such as butt welding and reinforcement of high-strength steel cables. It is equipped with a precision control system to ensure welding accuracy.

[0003] Currently, most bridge steel cable welding work still relies on traditional welding equipment, mainly manual welding, or only simple semi-automatic welding equipment. The degree of automation is low. When welding manually, welders need to work for a long time in a high-altitude and narrow environment. Not only is the labor intensity high, but the welding quality is also greatly affected by the individual skill level and condition of the welder. It is difficult to achieve standardized production, which makes bridge steel cable welding face great challenges in terms of efficiency, quality and safety.

[0004] However, in high-altitude operations, the traditional manual operation mode has significant drawbacks. On the one hand, continuous manual operation can easily lead to fatigue, resulting in a decline in welding quality and making it difficult to ensure the consistency and stability of the weld. On the other hand, steel cables are mostly located in dangerous high-altitude areas of bridges, and it is difficult for workers to maintain a stable posture, which not only affects welding accuracy but also poses great safety risks. Moreover, labor costs continue to rise with changes in the labor market, further increasing the cost of bridge construction.

[0005] Therefore, this utility model provides a welding device for reinforcing bridge steel cables to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a welding device for reinforcing bridge steel cables, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A welding device for reinforcing bridge steel cables includes a steel cable body, a sleeve fitted on the outer wall of the steel cable body, a fixing ring plate slidably connected to the inner walls of both ends of the sleeve, a magnetic ring for adsorbing the steel cable body to fix the device fixedly connected to the inner wall of each fixing ring plate, and a welding device for welding is fixedly installed on the top surface of the sleeve.

[0009] The sleeve consists of an upper cover plate and a lower cover plate, which are hinged together to achieve the opening and closing function, so as to be fitted onto the steel cable body and realize the quick installation and disassembly of the device.

[0010] Each of the fixed ring plates has a rotating component installed on one side close to each other to drive the welding equipment to rotate. The inner cavity of the sleeve is fixedly installed with a moving component to drive the welding equipment to move horizontally. Through the coordinated operation of the rotating component and the moving component, the welding equipment can achieve a combined rotation and movement along the steel cable body, thereby replacing the traditional manual operation mode, achieving the effect of fully automatic welding, reducing the safety risks of high-altitude operations, and realizing the automation, standardization and efficiency of bridge steel cable reinforcement welding.

[0011] As a further embodiment of this utility model, the rotating assembly includes a fixed gear ring, and two sets of fixed gear rings are provided in pairs. A gear is rotatably mounted on one side of each fixed ring plate, and the gear meshes with the fixed gear ring. A rotary motor for providing rotational power is fixedly installed on the inner wall of the upper cover plate, and the output shaft of the rotary motor is fixedly connected to a set of gears. The rotary motor drives the gears to rotate around the fixed gear ring, thereby driving the sleeve to make a circular motion around the steel cable body, avoiding welding blind spots.

[0012] As a further embodiment of this utility model, the moving component includes rollers, with two sets of three rollers arranged in groups of three. The two sets of rollers are located on the upper and lower sides of the steel cable body, respectively. A rotating rod for driving the roller to rotate is fixedly inserted into the inner cavity of each roller, and every two rotating rods are rotatably connected by a transmission belt. The transmission belt drives the rotating rod to rotate, thereby driving the roller to rotate. By utilizing the friction between the roller and the steel cable body, the entire device can move horizontally along the steel cable body, allowing the welding equipment to cover different positions along the axial direction of the steel cable body and complete long-distance welding operations.

[0013] As a further embodiment of this utility model, a positioning ring plate is fixedly installed on the inner wall of the sleeve, and a cleaning component is fixedly installed on the side of the positioning ring plate away from the welding equipment. This component is used to remove rust, oil, and other impurities from the surface of the steel cable before welding, thereby improving the welding quality and ensuring the weld bonding strength.

[0014] As a further embodiment of this utility model, the cleaning component includes a fixing rod, and there are multiple fixing rods, all of which are fixedly connected to the inner wall of the sleeve. A movable tube is slidably sleeved on one end of each fixing rod, and a cleaning brush for cleaning the surface of the steel cable body is fixedly connected to one end of the movable tube, and the cleaning brush is in contact with the outer wall of the steel cable body.

[0015] As a further embodiment of this utility model, the welding equipment consists of a control body and a welding machine body. The control body is fixedly connected to the upper cover plate via a fixing frame. The welding machine body is fixedly connected to the control body. A welding nozzle is fixedly installed at the bottom of the welding machine body and passes through the upper cover plate near the outer wall of the steel cable body.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. When this utility model is used, the rotating component and the moving component work together to enable the welding equipment to achieve a combined rotation and movement along the steel cable body, completely replacing the traditional manual welding mode. When working in dangerous areas at high altitudes on bridges, it avoids problems such as fatigue from continuous manual operation and difficulty in maintaining a stable posture, significantly reducing the safety risks of high-altitude operations. At the same time, it reduces labor costs, improves construction efficiency, and the automated operation mode can ensure the stability and consistency of the welding process, avoid the fluctuation of welding quality caused by differences in manual operation, realize the automation, standardization and efficiency of bridge steel cable reinforcement welding, and ensure the reliability of weld quality.

[0018] 2. When this utility model is in use, the cleaning brush in the cleaning component adaptively conforms to the surface of the steel cable under the action of the return spring, which can effectively remove impurities such as rust and oil before welding. The air pump, together with the jet pipe, further blows away surface debris, ensuring the cleanliness of the welding area. This improves the weld bonding strength and quality stability from the source and avoids welding defects caused by surface impurities. At the same time, the laser inspection sensor of the welding equipment can scan the outer surface of the steel cable in real time, accurately identify defects such as damage and cracks that need to be welded, making the welding operation more targeted, avoiding missed welds or blind welding, and further ensuring the welding.

[0028] 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.

[0029] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the utility model, a welding device for reinforcing bridge steel cables includes a steel cable body 1, a sleeve 2 is sleeved on the outer wall of the steel cable body 1, a fixing ring plate 4 is slidably connected to the inner walls of both ends of the sleeve 2, a magnetic ring 5 for adsorbing the steel cable body 1 to fix the device is fixedly connected to the inner wall of each fixing ring plate 4, and a welding device 6 for welding is fixedly installed on the top surface of the sleeve 2.

[0030] The sleeve 2 consists of an upper cover plate 201 and a lower cover plate 202, and the upper cover plate 201 and the lower cover plate 202 are hinged to each other to realize the opening and closing function, so as to be fitted onto the steel cable body 1 and realize the quick installation and disassembly of the device.

[0031] Each fixed ring plate 4 has a rotating component 7 installed on one side close to each other to drive the welding equipment 6 to rotate. Since manual operation is prone to fatigue during high-altitude work, it will lead to a decline in welding quality in the later stage. Moreover, steel cables are mostly located in dangerous high-altitude areas of bridges, and it is difficult for humans to maintain a stable posture. Therefore, a moving component 8 is fixedly installed in the inner cavity of the sleeve 2 to drive the welding equipment 6 to move horizontally. Through the coordinated operation of the rotating component 7 and the moving component 8, the welding equipment 6 can achieve a composite motion of rotation and movement along the steel cable body 1, thereby replacing the traditional manual operation mode, achieving the effect of fully automatic welding, reducing the safety risks of high-altitude work, and realizing the automation, standardization and efficiency of bridge steel cable reinforcement welding.

[0032] Specifically, a positioning block 203 is fixedly installed on the outer wall of the upper cover plate 201, and a buckle 204 is rotatably installed on the outer wall of the lower cover plate 202 through a pin. The buckle 204 and the positioning block 203 are interlocked to form a locking structure. Its function is to facilitate the opening and closing of the device onto the steel cable body 1 to complete the installation. After the interlocking and locking, it can ensure that the upper cover plate 201 and the lower cover plate 202 fit tightly together, fix the position of the entire welding device, prevent the device from shaking or shifting during the welding process, provide a stable working environment for the welding equipment 6, ensure welding accuracy and quality, and facilitate disassembly and maintenance.

[0033] Please see Figure 3 , Figure 5 The rotating component 7 includes a fixed gear ring 701, which is provided in two sets. Each fixed ring plate 4 has a gear 702 rotatably mounted on one side via a pin, and the gear 702 meshes with the fixed gear ring 701. A rotary motor 703 for providing rotational power is fixedly installed on the inner wall of the upper cover plate 201, and the output shaft of the rotary motor 703 is fixedly connected to a set of gears 702. The rotary motor 703 drives the gears 702 to rotate around the fixed gear ring 701, thereby driving the sleeve 2 to make a circular motion around the steel cable body 1. Combined with the moving component 8, the welding range covers the circumference of the steel cable, which meets the requirements for circumferential and spiral weld welding and avoids welding blind spots.

[0034] Specifically, the gears 702 are arranged in pairs, with a total of two sets, and the two sets of gears 702 and the two sets of fixed gear rings 701 are symmetrically and evenly distributed at both ends of the sleeve 2.

[0035] More specifically, a limiting block 704 is fixedly installed on the inner wall of the sleeve 2 to ensure the smooth rotation of both. The outer wall of the fixed ring plate 4 is provided with a rotating groove to provide rotation space for the limiting block 704, and the limiting block 704 is located in the rotating groove. At the same time, the outer wall of the limiting block 704 is provided with an inner concave surface, and the inner wall of the rotating groove that fits with it is provided with an outer convex surface. Thus, by using the concave-convex interlocking structure between the limiting block 704 and the rotating groove, a limiting constraint is formed on the rotating sleeve 2 to counteract the centrifugal force, vibration and other external forces generated by the rotation, to prevent the components from loosening or separating, to ensure the long-term stable operation of the rotating assembly 7, and to make the circumferential motion of the welding equipment 6 around the steel cable body 1 precise and reliable, providing a stable motion basis for the welding operation.

[0036] Please see Figure 4The moving component 8 includes rollers 801. There are two sets of rollers 801, with three rollers per set. The two sets of rollers 801 are located on the upper and lower sides of the steel cable body 1, respectively. Each roller 801 has a rotating rod 802 fixedly inserted into its inner cavity to drive the roller 801 to rotate. Every two rotating rods 802 are rotatably connected by a transmission belt 803. The transmission belt 803 drives the rotating rod 802 to rotate, thereby driving the roller 801 to rotate. By utilizing the friction between the roller 801 and the steel cable body 1, the entire device can move horizontally along the steel cable body 1, allowing the welding equipment 6 to cover different positions along the axial direction of the steel cable body 1 and complete long-distance welding operations.

[0037] Specifically, by using two sets of rollers 801 to adhere to the steel cable body 1 from top to bottom, and in conjunction with the linkage of the rotating rod 802 and the transmission belt 803, the force is balanced when the device moves, avoiding deviation and jamming, ensuring the smooth movement along the steel cable body 1, ensuring accurate welding trajectory, improving welding quality, thereby replacing manual operation of the device, improving construction efficiency and safety.

[0038] More specifically, a moving motor 804 for providing rotational power to the rotating rod 802 is fixedly installed on the outer wall of the upper cover plate 201. One end of the rotating rod 802 passes through the outer wall of the steel cable body 1 and is fixedly connected to the output end of the moving motor 804. One end of each rotating rod 802 is rotatably connected to the inner wall of the sleeve 2 through a bearing. A sleeve 805 for supporting the rotating rod 802 is fixedly installed on the inner wall of the sleeve 2, and the other end of each rotating rod 802 is located inside the sleeve 805.

[0039] More specifically, each rotating rod 802 has a pulley fixedly sleeved on its outer wall for limiting the transmission belt 803, and the transmission belt 803 is rotatably sleeved on the outside of the pulley. There are multiple transmission belts 803, which are distributed at both ends of the roller 801 and wrapped around the adjacent rollers 801 in an alternating arrangement. The transmission belts 803 connect different rollers 801 to form a transmission system, which helps the multiple rollers 801 to rotate in coordination and achieve stable conveying of the entire device.

[0040] Please see Figure 1 , Figure 2 , Figure 5 A positioning ring plate 3 is fixedly installed on the inner wall of the sleeve 2. A cleaning component 9 is fixedly installed on the side of the positioning ring plate 3 away from the welding equipment 6. It is used to remove rust, oil and other impurities from the surface of the steel cable before welding, improve the welding quality and ensure the weld bonding strength.

[0041] The cleaning component 9 includes a fixing rod 901. Multiple fixing rods 901 are provided and are all fixedly connected to the inner wall of the sleeve 2. A movable tube 902 is slidably sleeved on one end of each fixing rod 901. A cleaning brush 903 for cleaning the surface of the steel cable body 1 is fixedly connected to one end of the movable tube 902, and the cleaning brush 903 is in contact with the outer wall of the steel cable body 1.

[0042] Specifically, a return spring 904 is fixedly installed in the inner cavity of the moving tube 902, and one end of the return spring 904 is fixedly connected to the fixed rod 901. This allows the cleaning component 9 to work synchronously when the sleeve 2 moves. The cleaning brush 903 is attached to the surface of the steel cable body 1 to remove rust, oil and other impurities before welding, ensuring the welding area is clean, improving the weld bonding strength and quality stability. Furthermore, the return spring 904 allows the cleaning brush 903 to adapt to changes in the outer diameter of the steel cable body 1, maintaining constant pressure contact and avoiding cleaning blind spots.

[0043] More specifically, an air pump 905 is fixedly installed on the outer wall of the sleeve 2. The air supply end of the air pump 905 is fixedly connected to an air jet pipe 906 for auxiliary cleaning. The air jet pipe 906 is located on one side of the positioning ring plate 3. Air is supplied by the air pump 905 and sprayed out from the air jet pipe 906 to effectively blow away impurities on the surface of the steel cable body 1. At the same time, the outer wall of the sleeve 2 is provided with a slot, which allows the dust removed by the cleaning component 9 to fall off smoothly, avoiding the retention of debris that may affect the welding quality or equipment operation.

[0044] Please see Figure 6 The welding equipment 6 consists of a control body 601 and a welding machine body 602. The control body 601 is fixedly connected to the upper cover plate 201 via a fixing frame 603 and is used to integrate the welding power supply, parameter adjustment module and control device into a system. The welding machine body 602 is fixedly connected to the control body 601. A replaceable welding nozzle 604 is fixedly installed at the bottom of the welding machine body 602 and passes through the upper cover plate 201 near the outer wall of the steel cable body 1.

[0045] Specifically, the bottom of the welding machine body 602 is also equipped with a laser rangefinder, a welding torch, and a protective gas nozzle. The sensor can monitor the distance to the steel cable body 1 in real time. The welding torch has a wire feeding mechanism driven by a built-in servo motor. The protective gas nozzle surrounds the welding torch to provide an inert gas protective layer to ensure welding quality. A laser inspection sensor 605 is fixedly installed on the inner wall of the sleeve 2, which can scan and monitor the outer surface of the steel cable body 1 in real time and accurately identify whether there are defects such as damage or cracks that need to be welded.

[0046] The working principle of this utility model is as follows:

[0047] When using this utility model, first fasten the upper cover plate 201 and the lower cover plate 202 of the sleeve 2, and fix them by the buckle 204 and the positioning block 203. Combined with the adsorption effect of the magnetic ring 5 on the inner wall of the fixing ring plate 4, the device is stably fitted onto the steel cable body 1.

[0048] Furthermore, the main control unit 601 synchronously drives the rotating component 7 and the moving component 8 to operate, and the two combine to form a spiral welding trajectory that covers the entire surface of the steel cable. The rotating component 7's rotary motor 703 drives the gear 702 to mesh with the fixed gear ring 701, causing the sleeve 2 to rotate around the circumference of the steel cable body 1 to achieve circumferential welding. Simultaneously, the moving component 8's moving motor 804 drives the rotating rod 802, which in turn drives the roller 801 to rotate via the transmission belt 803. Axial movement is achieved by the friction between the roller 801 and the steel cable body 1.

[0049] Meanwhile, before welding, the cleaning component 9 rotates synchronously with the sleeve 2. The cleaning brush 903 adapts to the steel cable under the action of the return spring 904, and removes rust and oil stains by friction. The air pump 905 blows air through the air jet pipe 906 to assist in the discharge of impurities through the empty groove, ensuring that the welding surface is clean.

[0050] Finally, the laser inspection sensor 605 scans for defects in the steel cable body 1 in real time and provides feedback. When a defect is detected on the outer surface of the steel cable body 1, the welding machine body 602 and the welding nozzle 604 are driven to perform welding. Combined with the laser range sensor, the distance between the welding nozzle 604 and the steel cable is ensured to be accurate. With the help of the welding gun wire feeding mechanism and the protective gas protection, the welding quality is ensured. This enables the device to achieve automated and standardized operation, reduce the risk of high-altitude operations, and improve the efficiency and reliability of bridge steel cable reinforcement welding.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
