Description

Technical Field

[0001] The present invention relates to an orthopedic welding device, and particularly to a rapid orthopedic welding device for steel reinforcement cages in bridge construction. Background Art

[0002] In bridge construction, as an important part of the load-bearing structure, the welding quality of the steel reinforcement cage directly affects the safety and stability of the bridge. The application of the rapid orthopedic welding device for steel reinforcement cages in bridge construction helps to improve the welding quality and efficiency of the steel reinforcement cage, reduce the construction cost, and is an indispensable important device in the field of bridge construction.

[0003] In this regard, Chinese Patent Application No.: 202211330995.9 discloses a welding device for steel reinforcement cages, including a base, a fixed seat fixedly installed on the base, and a sliding seat movably installed. Rotating discs are rotatably connected to both the sliding seat and the fixed seat, and through holes for multiple steel bars to pass through are provided on the rotating discs. A plurality of limiting cylinders for limiting the steel bars are arranged in the through holes. An automatic rolling welder for automatically welding the connection points of the steel bars is arranged on one side close to the fixed seat, and a steel bar winding machine for winding the steel bars is arranged on the side of the fixed seat away from the automatic rolling welder. A support seat is fixedly installed on the base, and an electric push rod is installed at the bottom of the support seat, and the output shaft of the electric push rod penetrates the upper surface of the support seat, which can realize the individual detection of welding, and perform supplementary welding and marking on the unqualified welded joints, facilitating manual inspection and improving the welding efficiency of the steel reinforcement cage.

[0004] In this regard, Chinese Patent Application No.: 202210558900.2 discloses a welding device for steel reinforcement cages in bridge construction, including a welding machine, a welding head, a support plate and a fixed disc. The bottom end of the support plate; the bottom end of the welding head is symmetrically connected with support rails through a sliding structure, and a support base is fixed at the bottom end of the support rail. The debris with sparks generated during the welding of the welding head is collected through a collection box, and it is cooled with cold water. While facilitating the collection of debris, it also avoids the safety hazard caused by the splashing of debris with too high temperature, improving the practicability of the welding device. The debris entering the interior of the collection box can be collected through a support frame. After the support frame is taken out separately, it is convenient to clean the debris, so that the collection box does not need to be separately disassembled during cleaning, improving the convenience of using the welding machine. Through the adjustable design of the support plate, the distance between the two support plates can be adjusted according to the length of the steel reinforcement cage during welding, so as to adapt to steel reinforcement cages of different lengths, greatly improving the application range of the welding device.

[0005] Combined with the above comparative documents and the existing technology, it is described that:

[0006] During the welding process of the steel reinforcement cage, the welding device needs to be moved to complete the welding operations at different positions. However, during the mobile welding process, it is sometimes interfered by the deformation of the steel bars. For example, the steel reinforcement cage may be deformed outward due to the influence of high-temperature weather, resulting in deviation of the welding position. Therefore, a welding device that can correct the steel reinforcement cage before welding needs to be designed;

[0007] Since the steel reinforcement cage is generally long in size, multiple positions of the steel reinforcement cage need to be welded during actual welding. Therefore, the welding device needs to be continuously moved and adjusted, which will consume a large amount of time and reduce the overall efficiency. Therefore, a welding device that can automatically adjust its position needs to be designed. Summary of the Invention

[0008] The purpose of the present invention is to provide a rapid orthopedic welding device for steel reinforcement cages used in bridge construction to solve the problems raised in the above background technology.

[0009] To achieve the above purpose, the present invention provides the following technical solution: A rapid orthopedic welding device for steel reinforcement cages used in bridge construction, including a welding frame, a welding point moving mechanism, a welding mechanism, and an auxiliary correction mechanism. The welding mechanism is arranged on the upper surface of the two welding frames. The welding mechanism includes a welding ring, an electric push rod, a spot welder, and a fixed ring. The welding ring is arranged on the upper side between the two welding frames. A plurality of auxiliary correction mechanisms are arranged on the outer surface of the welding frame. The auxiliary correction mechanism includes a bending arm, a correction steel plate, a connecting rod, a coloring ink box, a rotating ball, an adsorption cotton, and a correction steel plate. A plurality of bending arms are fixedly connected to the welding ring, and the plurality of bending arms are annularly arranged on the outer surface of the welding ring. The lower surface of the end of the bending arm away from the welding ring is fixedly connected to a correction steel plate. A positioning plate is fixedly connected to the outer surface of the bending arm. A coloring ink box is fixedly connected to the side of the positioning plate away from the bending arm. A rotating ball is arranged in the middle of the inner side of the coloring ink box. The inner end of the rotating ball is embedded in the interior of the coloring ink box. Wear-resistant dust-proof paint is arranged in the interior of the coloring ink box. Adsorption cotton is arranged on both sides of the rotating ball. The inner ends of the two adsorption cottons both penetrate through the interior of the coloring ink box.

[0010] As a preferred technical solution of the present invention, the welding point moving mechanism is arranged on the upper surface of the two welding frames. The welding point moving mechanism includes a limiting plate, a rotating lead screw, a moving slider, a limiting slide rail, a driving motor, and a connecting plate. Limiting plates are fixedly connected to the left and right sides of the upper surface of the welding frame. A rotating lead screw is rotatably connected between the two limiting plates. Two moving sliders are threadedly connected to the outer surface of the rotating lead screw. The lower ends of the two moving sliders are both slidably connected to the upper surface of the limiting slide rail. The lower end of the limiting slide rail is fixedly connected to the upper surface of the welding frame.

[0011] With the above technical solution, after the moving slider moves outside the rotating lead screw, the moving slider can slide on the limiting slide rail, and the limiting slide rail can play a limiting role on the moving slider.

[0012] As a preferred technical solution of the present invention, the inner sides of the two moving sliders are fixedly connected to the outer side of the connecting plate, the inner side of the connecting plate is fixedly connected to the welding ring, four fixing rings are fixedly connected to the outer surface of the welding ring, electric push rods are fixedly connected to the outer surfaces of the four fixing rings, the output ends of the electric push rods penetrate through the inner side of the welding ring, and the output ends of the electric push rods are fixedly connected with spot welders.

[0013] With the above technical solution, when welding different positions of the steel reinforcement cage, by controlling the rotation of the rotating lead screw by the driving motor, after the rotating lead screw rotates, the two moving sliders threadedly connected to the outside of the rotating lead screw can move together with the welding ring in the radial direction of the placed steel reinforcement cage, and in this way, the position of the welding ring can be adjusted, and the spot welder inside the welding ring can weld different positions of the steel reinforcement cage.

[0014] As a preferred technical solution of the present invention, a driving motor is fixedly connected to the outer surface of the limiting plate, and the output end of the driving motor is in transmission connection with the rotating lead screw.

[0015] With the above technical solution, the rotating lead screw can be rotated under the action of the driving motor.

[0016] As a preferred technical solution of the present invention, a plurality of connecting rods are fixedly connected to the outer surface of the welding ring, one ends of the plurality of connecting rods far away from the welding ring are fixedly connected to the inner side of the cooling and temperature-reducing ring, a plurality of air-cooling pipes are fixedly connected to the inner surface of the cooling and temperature-reducing ring, rotating fans are arranged inside the plurality of air-cooling pipes, motors are arranged at the connection positions of the rotating fans and the air-cooling pipes, and the output ends of the motors are in transmission connection with the rotating fans.

[0017] With the above technical solution, since the cooling and temperature-reducing ring is arranged at the rear side position of the welding ring, when the welding ring moves to the next welding position of the steel reinforcement cage, the cooling and temperature-reducing ring moves to the previous welding position. There are rotating fans driven by motors inside the cooling and temperature-reducing ring, and the previous welding position of the steel reinforcement cage is cooled and dissipated by the rotating fans. Blowing and cooling can reduce the temperature around the weld and reduce the range of the heat-affected zone.

[0018] As a preferred technical solution of the present invention, a plurality of fixing steel sheets are fixedly connected between the two welding frames, the plurality of fixing steel sheets are evenly horizontally distributed inside the two welding frames, and support pads are fixedly connected to the upper surfaces of the plurality of fixing steel sheets.

[0019] With the above technical solution, the plurality of fixing steel sheets are used to connect the two welding frames.

[0020] As a preferred technical solution of the present invention, a connection block is fixedly connected to the outer surface of the support pad, and infrared emitters are fixedly connected to both the left and right sides of the outer surface of the connection block.

[0021] Through the above technical solution, the infrared emitter can emit infrared information for the infrared induction switch to receive.

[0022] As a preferred technical solution of the present invention, a through groove is opened in the inner side of the lower end of the welding ring, an infrared induction switch is arranged on the inner wall of the through groove, and the infrared induction switch is electrically connected to the electric push rod.

[0023] Through the above technical solution, during the movement of the welding ring, when the infrared induction switch on the surface of the through groove on the inner side of the lower end of the welding ring moves to the same plane position as the infrared emitter, the infrared induction switch receives the infrared information of the infrared emitter and triggers the output end of the electric push rod to move outward, causing the spot welder to move outward, preventing the position of the spot welder from affecting the passage of the welding ring through the support ring.

[0024] As a preferred technical solution of the present invention, a support ring is fixedly connected to the upper surface of the connection block, and a steel reinforcement cage body is arranged inside the support ring.

[0025] Through the above technical solution, the width of the support ring is smaller than the gap between the correction steel plate and the steel reinforcement cage. During the movement of the welding ring, the correction steel plate will not interfere with the movement of the support ring.

[0026] As a preferred technical solution of the present invention, an auxiliary reference plate is fixedly connected to the outer surface of the coloring ink box.

[0027] Through the above technical solution, during the correction of the steel reinforcement cage, the position of the auxiliary reference plate and the steel reinforcement cage can be used to assist in judging whether the current steel reinforcement cage is deformed.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] Through the auxiliary correction mechanism provided in the present invention, during the process of the welding ring moving for welding, if the internal steel bar structure of the steel reinforcement cage deforms outward in a high-temperature environment, after the correction steel plate on the outer side of the welding ring moves to the position where the steel reinforcement cage deforms outward, the correction steel plate will apply pressure to the position where the steel reinforcement cage deforms outward, so that the deformed position of the steel bar will converge inward by a certain distance, which is used to play an auxiliary correction role. In addition, if the steel bars inside the steel reinforcement cage are deformed outward, the steel bars at the deformed position will contact the rotating balls and the adsorption cotton on the lower surface of the coloring ink box. During the subsequent movement of the welding ring, the rotating balls will have a rolling effect on the deformed position of the steel bar. After the rotating balls roll, the wear-resistant and dust-proof paint in the coloring ink box can be brushed on the position where the steel reinforcement cage deforms outward, and at the same time, the adsorption cotton will brush the wear-resistant and dust-proof paint on the side position where the steel reinforcement cage deforms, so as to mark the area where the steel reinforcement cage deforms outward. After observing the color of the wear-resistant and dust-proof paint on the surface of the steel reinforcement cage, the staff can understand that the current position of the steel reinforcement cage has a situation of outward deformation. If the correction force of the correction steel plate is insufficient, the staff can use other tools to correct the steel reinforcement cage after obtaining the deformed position;

[0030] Through the welding point moving mechanism provided in the present invention, when welding different positions of the steel reinforcement cage, the driving motor is used to control the rotation of the rotating lead screw. After the rotating lead screw rotates, the two moving sliders threadedly connected to the outer side of the rotating lead screw can move together with the welding ring in the radial direction of the placed steel reinforcement cage. In this way, the position of the welding ring can be adjusted, and the spot welder inside the welding ring can weld different positions of the steel reinforcement cage. In addition, during the movement of the welding ring, when the infrared induction switch on the surface of the through groove inside the lower end of the welding ring moves to the same plane position as the infrared emitter, the infrared induction switch receives the infrared information of the infrared emitter and triggers the output end of the electric push rod to move outward, so that the spot welder moves outward to prevent the position of the spot welder from affecting the passage of the welding ring through the support ring;

[0031] Through the cooling and temperature reduction ring provided in the present invention, since the cooling and temperature reduction ring is arranged at the rear side of the welding ring, when the welding ring moves to the next welding position of the steel reinforcement cage, the cooling and temperature reduction ring moves to the previous welding position. A rotating fan driven by a motor is arranged inside the cooling and temperature reduction ring, and the previous welding position of the steel reinforcement cage is cooled and dissipated by the rotating fan. Blowing and cooling can reduce the temperature around the weld and reduce the range of the heat affected zone. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1-7 , the present invention provides a technical solution for a rapid orthopedic welding device for steel reinforcement cages used in bridge construction:

[0042] According to Figure 1 , Figure 2 and Figure 3 , Figure 5 and Figure 7As shown in the figure, a rapid orthopedic welding device for steel reinforcement cages in bridge construction includes a welding frame 1, a welding point moving mechanism 2, a welding mechanism 3, and an auxiliary correction mechanism 4. A welding mechanism 3 is arranged on the upper surfaces of two welding frames 1. The welding mechanism 3 includes a welding ring 301, an electric push rod 302, a spot welder 303, and a fixing ring 304. The welding ring 301 is arranged on the upper side between the two welding frames 1. A plurality of auxiliary correction mechanisms 4 are arranged on the outer surface of the welding frame 1. The auxiliary correction mechanism 4 includes a bending arm 401, a correction steel plate 402, a connecting rod 5, a coloring ink box 404, a rotating ball 405, an adsorption cotton 406, and a correction steel plate 402.

A positioning plate 403 is fixedly connected to the outer surface of the bending arm 401.

If the steel bars inside the steel reinforcement cage are deformed outward, the deformed steel bars will contact the rotating ball 405 and the adsorption cotton 406 on the lower surface of the coloring ink box 404. During the subsequent movement of the welding ring 301, the rotating ball 405 has a rolling effect on the deformed position of the steel bar. After the rotating ball 405 rolls, the wear-resistant dust-proof paint inside the coloring ink box 404 can be painted on the outward deformed position of the steel reinforcement cage. At the same time, the adsorption cotton 406 paints the wear-resistant dust-proof paint on the deformed side position of the steel reinforcement cage, so as to mark the outward deformed position area of the steel reinforcement cage. After observing the color of the wear-resistant dust-proof paint on the surface of the steel reinforcement cage, the staff can understand that there is an outward deformation at the current position of the steel reinforcement cage. If the correction force of the correction steel plate 402 is insufficient, the staff can use other tools to correct the steel reinforcement cage after obtaining the deformed position.

Two moving sliders 203 are threadedly connected to the outer surface of the rotating lead screw 202. The lower ends of the two moving sliders 203 are slidably connected to the upper surface of the limit slide rail 204. The lower end of the limit slide rail 204 is fixedly connected to the upper surface of the welding frame 1.

The inner side of the connecting plate 206 is fixedly connected to the welding ring 301. Four fixing rings 304 are fixedly connected to the outer surface of the welding ring 301. Electric push rods 302 are fixedly connected to the outer surfaces of the four fixing rings 304. The output ends of the electric push rods 302 are disposed through the inner side of the welding ring 301, and the output ends of the electric push rods 302 are fixedly connected to spot welders 303. A driving motor 205 is fixedly connected to the outer surface of the limit plate 201. The output end of the driving motor 205 is in transmission connection with the rotating lead screw 202. A plurality of connecting rods 5 are fixedly connected to the outer surface of the welding ring 301. One ends of the plurality of connecting rods 5 away from the welding ring 301 are fixedly connected to the inner side of the cooling and temperature reduction ring 6. A plurality of air-cooling pipes 7 are fixedly connected to the inner surface of the cooling and temperature reduction ring 6. The plurality of air-cooling pipes 7 are annularly and arrayedly distributed on the inner side of the cooling and temperature reduction ring 6, and the welding positions of the plurality of air-cooling pipes 7 and the reinforcing cage body 9 are disposed on the same plane. Rotating fans 8 are disposed inside the plurality of air-cooling pipes 7. Motors are disposed at the connection positions of the rotating fans 8 and the air-cooling pipes 7. The output ends of the motors are in transmission connection with the rotating fans 8.

[0044] According to Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown in the figure, a plurality of fixing steel sheets 10 are fixedly connected between the two welding frames 1. The plurality of fixing steel sheets 10 are horizontally evenly distributed inside the two welding frames 1. Support pads 11 are fixedly connected to the upper surfaces of the plurality of fixing steel sheets 10. Connection blocks 13 are fixedly connected to the outer surfaces of the support pads 11. Infrared emitters 14 are fixedly connected to the left and right sides of the outer surface of the connection blocks 13. A through groove is formed in the inner side of the lower end of the welding ring 301. An infrared induction switch 15 is disposed on the inner wall of the through groove. The infrared induction switch 15 is electrically connected to the electric push rod 302. A support ring 12 is fixedly connected to the upper surface of the connection block 13. The support ring 12 is made of steel structure. A reinforcing cage body 9 is disposed inside the support ring 12.

[0045] During actual use, for a rapid orthopedic welding device for bridge construction reinforcement cages according to the present invention, the welding device is placed at the bridge construction site, and then the reinforcement cage body 9 to be welded is placed inside the welding device, so that the reinforcement cage body 9 is located inside multiple support rings 12. By controlling the rotation of the rotating lead screw 202 with the driving motor 205, after the rotation of the rotating lead screw 202, the two moving sliders 203 threadedly connected to the outside of the rotating lead screw 202 can move together with the welding ring 301 in the radial direction of the placed reinforcement cage body 9. In this way, the position of the welding ring 301 can be adjusted, enabling the spot welder 303 inside the welding ring 301 to weld different positions of the reinforcement cage body 9. Additionally, during the movement of the welding ring 301, when the infrared induction switch 15 on the surface of the through groove inside the lower end of the welding ring 301 moves to the same plane position as the infrared emitter 14, the infrared induction switch 15 receives the infrared information of the infrared emitter 14 and triggers the output end of the electric push rod 302 to move outward, causing the spot welder 303 to move outward to prevent the position of the spot welder 303 from affecting the passage of the welding ring 301 through the support ring 12. When the welding ring 301 moves to the next welding position of the reinforcement cage body 9, the cooling and temperature reduction ring 6 moves to the previous welding position. The cooling and temperature reduction ring 6 is internally provided with a rotating fan 8 driven by a motor, and the rotating fan 8 cools and dissipates heat from the welding position of the previous reinforcement cage body 9. Blowing air for cooling can reduce the temperature around the weld seam and reduce the range of the heat affected zone. During the process of the welding ring 301 moving for welding, if the internal steel bar structure of the reinforcement cage body 9 deforms outward in a high-temperature environment, after the correction steel plate 402 outside the welding ring 301 moves to the position where the reinforcement cage body 9 deforms outward, the correction steel plate 402 applies pressure to the position where the reinforcement cage body 9 deforms outward, so that the deformed position of the steel bar converges inward by a certain distance, serving an auxiliary correction role. Additionally, if the steel bars inside the reinforcement cage body 9 are deformed outward, the deformed steel bars will contact the rotating balls 405 and the adsorption cotton 406 on the lower surface of the coloring ink cartridge 404. During the subsequent movement of the welding ring 301, the rotating balls 405 roll with the deformed position of the steel bar. After the rotation of the rotating balls 405, the wear-resistant dust-proof paint in the coloring ink cartridge 404 can be brushed on the position where the reinforcement cage body 9 deforms outward, and at the same time, the adsorption cotton 406 brushes the wear-resistant dust-proof paint on the side position where the reinforcement cage body 9 deforms, thereby marking the position area where the reinforcement cage body 9 deforms outward. After observing the color of the wear-resistant dust-proof paint on the surface of the reinforcement cage body 9, the staff can understand that the current position of the reinforcement cage body 9 has an outward deformation situation. If the correction force of the correction steel plate 402 is insufficient, after obtaining the deformed position, the staff can use other tools to correct the reinforcement cage body 9. After welding, the reinforcement cage body 9 is removed, and the welded reinforcement cage body 9 can be used for subsequent bridge construction.
