Description

Technical Field

[0001] This application relates to the field of bending repair of steel pipe towers, and particularly to a bending repair device for steel pipe towers. Background Art

[0002] Steel pipe towers are tower-shaped structures used to support and carry various types of communication equipment, such as radios, microwaves, satellites, etc. They play a role in connecting and transmitting communication signals and are usually widely used in fields such as telecommunications, broadcasting, television, and the Internet. Steel pipe towers are generally made of steel, including angle steel, so they have high strength and stability and can withstand the influence of harsh environments and weather conditions. If the angle steel at a certain part of the steel pipe tower is bent, it will affect the stability of the steel pipe tower. Therefore, it is necessary to repair the bent part of the angle steel in time and reinforce the angle steel to prevent the angle steel from being bent again after repair.

[0003] In the existing steel pipe bending repair devices, such as the Chinese patent with the publication number CN114603002 B, a steel pipe repair and straightening device is disclosed. Specifically, when using this device to correct and repair a bent and sunken steel pipe, first place the bent part of the steel pipe to be processed above the center of the operation disk and keep the steel pipe parallel to the upper end face of the operation disk. Then, rotate the first rotating sleeve to make the straightening device extend into the steel pipe and approach the bent part of the steel pipe along the radial direction of the operation disk. The straightening device presses against the inner side wall of the steel pipe, and the two straightening devices respectively clamp the operation disk and the straightening gear. The straightening gear drives one straightening device to rotate through the force application gear and the force application mechanism. Under the combined action of the two straightening devices, the bent steel pipe is corrected. At the same time, the invention makes the auxiliary disk fit the steel pipe on one side of the moving device fixed to the operation disk by rotating the auxiliary disk and rotating the third bolt, and at the same time locks the auxiliary disk on the operation disk through the fourth bolt, ensuring that no secondary bending occurs during the process of straightening the steel pipe. After the steel pipe is straightened, the clamped steel pipe is fixed by the clamping mechanism in the repair device, and the side wall of the steel pipe is extruded by the rolling mechanism to make the depression on the side wall of the steel pipe flat, so that the depression on the steel pipe is flat.

[0004] The above-mentioned prior art can also achieve the function of bending repair of steel pipes. However, on the one hand, the above-mentioned prior art device is relatively complex and cannot achieve the bending repair function of steel pipe towers in the air. On the other hand, the above-mentioned prior art cannot reinforce the repaired steel pipe, and the repaired steel pipe may be bent again in a short time. Based on this, there is still room for improvement on the basis of the existing steel pipe tower bending repair device. Summary of the Invention

[0005] In order to be able to achieve the bending repair function of the bent angle steel on the steel pipe tower and be able to reinforce the repaired angle steel. The present application provides a bending repair device for a steel pipe tower.

[0006] The bending repair device for a steel pipe tower provided by the present application adopts the following technical solutions:

[0007] A bending repair device for a steel pipe tower includes a U-shaped frame, a fixing module, a positioning module and a welding module. The cross-section of the U-shaped frame is in a U-shaped structure. Fixing modules are respectively installed at the left and right ends of the U-shaped frame.

[0009] By adopting the above technical solutions, when it is necessary to repair the bent angle steel, first adjust the position of the sliding plate so that the connecting block can be clamped on the steel pipe tower. Then connect the clamping block to the end of the connecting block, and the connecting block and the clamping block can be connected together through screws, so that the U-shaped frame can be fixed on the steel pipe tower. At this time, the angle steel to be repaired is located inside the U-shaped frame.

[0010] The positioning module includes a positioning frame, a first slide rail, a repair frame, a moving unit and a clamping unit. First slide rails are symmetrically installed at the upper end inside the U-shaped frame. The cross-section of the first slide rail is in an arc structure. A positioning frame is slidably arranged at the lower ends of the two first slide rails. A moving unit is installed above the middle of the positioning frame in a threaded cooperation manner.

[0011] By adopting the above technical solutions, after the U-shaped frame is fixed on the steel pipe tower, move the welding module upward, and the clamping unit connects the positioning frame and the welding module together. At this time, the upper and lower end faces of the angle steel are respectively in close contact with the positioning frame and the welding module. Then shake the moving unit so that the positioning frame can move left and right reciprocally on the first slide rail, thereby realizing the repair function of the repair frame for the bent part of the angle steel. After the repair is completed, the welding module welds and reinforces the angle steel.

[0012] The welding module includes a triangular mold frame, a welding unit, a stock storage unit, and a lifting unit.

The stock storage unit is clamped with the clamping unit. The triangular mold frame is installed on the stock storage unit. The triangular mold frame is made of a hard material. A triangular through groove is provided in the triangular mold frame, and the welding unit is installed in the triangular through groove.

[0013] By adopting the above technical solution, the lifting unit drives the triangular mold frame and the stock storage unit to move upward, so that the angle steel is located between the triangular mold frame and the repair frame, and at this time, the angle steel is in close contact with the triangular mold frame and the repair frame. Through the mutual rolling extrusion of the triangular mold frame and the repair frame on the bent part of the angle steel, the bent part of the angle steel can be successfully repaired. Subsequently, the stock storage unit pushes the reinforcement plates upward one by one, and the welding unit applies a soldering flux to the reinforcement plates and performs welding, so that the reinforcement plates can be adhered to the angle steel, realizing the reinforcement function of the repaired angle steel.

[0014] Preferably, a repair groove is provided on the repair frame. Repair shafts are uniformly installed on the side wall of the repair groove. The surface of the repair shaft is smooth. The repair shaft is made of a hard material. The end face of the repair shaft is in close contact with the angle steel.

[0015] By adopting the above technical solution, when repairing the bent part of the angle steel, by driving the left and right movement of the positioning frame through the moving unit, the repair shafts uniformly installed on the side wall of the repair groove can perform rolling repair on the bent part of the angle steel, so that the repair is more thorough.

[0016] Preferably, the moving unit includes a threaded column, a fixed frame, an annular gear, a bevel gear, a rotating shaft, and a rotating handle. The ends of the U-shaped frame are symmetrically installed with fixed frames through screws. The inside of the fixed frame is a hollow structure.

[0017] By adopting the above technical solution, when repairing the angle steel, shake the rotating handle, the annular gear and the bevel gear are combined, so as to drive the threaded column to rotate. The threaded column drives the positioning frame to perform a reciprocating motion above the angle steel, and the repair frame thus performs rolling extrusion repair on the bent part of the angle steel, which is beneficial to the full repair of the angle steel.

[0018] Preferably, the clamping unit includes a connecting plate, a locking plate, and a locking screw. The connecting plates are uniformly installed at the lower end of the positioning frame.

The locking plate is in a rectangular structure. The locking screw is installed on the side wall of the connecting plate and is connected to the locking plate.

[0019] By adopting the above technical solution, when the lifting unit drives the welding module to move under the positioning frame, the connecting plate is clamped with the welding module. After that, the locking plate is pushed outwards, and then the locking screw is turned to connect the locking plate with the welding module, thereby realizing the clamping function between the positioning frame and the welding module, which is beneficial to the synchronous movement of the positioning frame and the welding module, and further fully repairing the angle steel.

[0020] Preferably, the welding unit includes a telescopic cylinder I, a triangular frame, a moving frame, a spring I, a telescopic plate and a welding head.

A telescopic groove is provided on the moving frame, and a telescopic plate is slidably arranged in the telescopic groove. An inclined surface that is in close contact with the inclined groove is provided at the upper end of the telescopic plate. A spring I is installed between the lower end of the telescopic plate and the telescopic groove. Triangular plates are evenly installed on the outer side of the telescopic plate, and welding heads are installed on the triangular plates. The welding heads are arranged obliquely.

[0021] By adopting the above technical solution, after the angle steel is repaired, the stockpiling unit pushes the reinforcement plate upwards, so that the reinforcement plate is in close contact with the inner wall of the angle steel. The telescopic cylinder I is started, and the telescopic cylinder I drives the moving frame to move to the right. The telescopic plate gradually extends out of the telescopic groove, thereby driving the welding head to move to the gap between the angle steel and the reinforcement plate. The welding head can realize the function of accurately welding and fixing between the angle steel and the reinforcement plate. After welding, the telescopic cylinder I first drives the moving frame to move to the left, thereby realizing the function of retracting the welding head into the triangular die frame, and thus realizing the function of strengthening the angle steel.

[0022] Preferably, the stockpiling unit includes a stockpiling frame, a feeding mechanism, a pushing mechanism and a storage battery. The stockpiling frame is installed on the lifting unit. A rectangular groove that cooperates with the connecting plate is provided on the stockpiling frame. A through groove that cooperates with the locking plate is provided on the inner wall of the rectangular groove. A rectangular opening is provided on the upper right side of the stockpiling frame. The stockpiling frame is of a hollow structure. A feeding mechanism is installed above the interior of the stockpiling frame, a storage battery is installed below the interior of the stockpiling frame, and a pushing mechanism is installed at the right end of the interior of the stockpiling frame.

[0023] By adopting the above technical solution, after the angle steel is repaired, the pushing mechanism pushes the reinforcement plate stored in the feeding mechanism upwards through the rectangular opening, so as to weld the surface of the reinforcement plate.

[0024] Preferably, the lifting unit includes a mounting frame, a slide rail II and a telescopic rod. The mounting frame is slidably arranged at the upper end of the middle part of the U-shaped frame. The mounting frame is of a U-shaped structure. The telescopic rods are evenly installed at the lower end of the mounting frame. Cylindrical through grooves are symmetrically provided below the middle part of the stockpiling frame. Slide rails II are slidably arranged in the cylindrical through grooves, and the ends of the slide rails II are connected to the side walls of the mounting frame.

[0025] By adopting the above technical solution, when the positioning frame stays directly above the bending position of the angle steel, pull the mounting frame upward, and at the same time adjust the left-right sliding of the mounting frame on the second slide rail, so that the storage rack can be engaged with the positioning frame, thereby achieving accurate repair of the bending position of the angle steel.

[0026] Preferably, the feeding mechanism includes a connecting frame, a feeding frame, a second spring and a pushing plate. A feeding frame is installed above the middle of the storage rack. The feeding frame is in an L-shaped structure. A second spring is installed on the inner wall of the feeding frame. The end of the second spring is connected to a pushing plate. Reinforcing plates are evenly placed on the feeding frame. The pushing plate is always in close contact with the reinforcing plates. The reinforcing plates are made of iron. Chutes are symmetrically arranged on the inner wall of the storage rack. The pushing plate slides in the chutes. A connecting frame is installed at the outer end of the feeding frame.

[0027] By adopting the above technical solution, after the repair of the angle steel is completed, the pushing plate pushes the reinforcing plates into the pushing mechanism one by one, and only one reinforcing plate can be placed in the pushing mechanism. Subsequently, the pushing mechanism drives the reinforcing plate to be pushed upward through the rectangular opening, which is beneficial to welding the reinforcing plate. At this time, the lower end of the pushing mechanism blocks the right end of the feeding frame to prevent the reinforcing plates from falling from the end of the feeding frame.

[0028] Preferably, the pushing mechanism includes an L-shaped frame, a magnet, a baffle and a second telescopic cylinder. A second telescopic cylinder is installed at the lower right of the middle of the storage rack. The end of the second telescopic cylinder is connected to an L-shaped frame. Magnets are symmetrically installed on the inner wall of the L-shaped frame. A baffle is installed at the lower end of the L-shaped frame.

[0029] By adopting the above technical solution, after the repair of the angle steel is completed, start the second telescopic cylinder. The second telescopic cylinder drives the L-shaped frame and the reinforcing plate to move upward. At this time, the magnets symmetrically installed on the inner wall of the L-shaped frame tightly adsorb the reinforcing plate to prevent the reinforcing plate from falling during the upward movement and welding process; when the L-shaped frame drives the reinforcing plate to move to the upper end of the storage rack, the baffle blocks the right end of the feeding frame to prevent the reinforcing plates stored in the feeding frame from falling; after the welding of the reinforcing plate is completed, start the second telescopic cylinder. The second telescopic cylinder drives the L-shaped frame to move downward. At this time, the pushing plate pushes the reinforcing plate into the L-shaped frame again, which is beneficial to the function of pushing the reinforcing plates out one by one.

[0032] 2. The present invention is provided with a welding unit. After the bent part of the angle steel is repaired, the telescopic cylinder II pushes the reinforcement plates stored in the feeding rack upward in sequence through the L-shaped frame, and the telescopic cylinder I pushes the triangular frame outward, thereby welding the reinforcement plates. After cooling for a period of time, the angle steel can be fully adhered to the reinforcement plates, thus realizing the reinforcement function of the angle steel.

Detailed implementation manners

[0049] The following further elaborates on the present application in conjunction with the attached Figures 1-13 for a more detailed description.

[0050] The embodiment of the present application discloses a steel pipe tower bending repair device, which can repair the bent angle steel on the steel pipe tower and can reinforce the repaired angle steel.

[0051] Referring to Figure 1 , a steel pipe tower bending repair device includes a U-shaped frame 1, a fixed module 2, a positioning module 3 and a welding module 4. The cross-section of the U-shaped frame 1 is in a U-shaped structure. Fixed modules 2 are respectively installed at the left and right ends of the U-shaped frame 1. A positioning module 3 is installed above the middle of the U-shaped frame 1. A welding module 4 is installed below the middle of the U-shaped frame 1. The positioning module 3 and the welding module 4 cooperate with each other.

[0052] Referring to Figure 2 , Figure 4 , Figure 9 and Figure 11, in order to fix the steel pipe tower, a fixing module 2 is provided in this embodiment. The fixing module 2 includes a rectangular sleeve 21, a sliding plate 22, a fixing shaft 23, a connecting block 24 and a clamping block 25. Rectangular sleeves 21 are symmetrically installed on the side walls of the U-shaped frame 1. The inside of the rectangular sleeve 21 is a hollow structure. A sliding plate 22 is slidably arranged inside the rectangular sleeve 21. A fixing shaft 23 is installed on the sliding plate 22. A connecting block 24 is installed at the end of the fixing shaft 23. The cross section of the connecting block 24 is a U-shaped structure. A clamping block 25 is installed at the end of the connecting block 24 by screws. The cross section of the clamping block 25 is a U-shaped structure.

[0053] During the actual use process, when it is necessary to repair the bent angle steel, first adjust the position of the sliding plate 22 so that the connecting block 24 can be stuck on the steel pipe tower. Then connect the clamping block 25 to the end of the connecting block 24. The connecting block 24 and the clamping block 25 can be connected together by screws, so that the U-shaped frame 1 can be fixed on the steel pipe tower. At this time, the angle steel to be repaired is located inside the U-shaped frame 1.

[0054] Refer to Figure 2 , Figure 3 , Figure 9 and Figure 10 , in order to position the bent angle steel, a positioning module 3 is provided in this embodiment. The positioning module 3 includes a positioning frame 31, a first slide rail 32, a repair frame 33, a moving unit 34 and a clamping unit 35. First slide rails 32 are symmetrically installed at the upper end inside the U-shaped frame 1. The cross section of the first slide rail 32 is an arc structure. A positioning frame 31 is slidably arranged at the lower ends of the two first slide rails 32. A moving unit 34 is installed above the middle of the positioning frame 31 in a threaded cooperation manner. The end of the moving unit 34 is installed at the left and right ends of the U-shaped frame 1. A triangular groove is provided at the lower end of the middle of the positioning frame 31. Repair frames 33 are symmetrically installed on the inner wall of the triangular groove. Clamping units 35 are evenly installed on the lower end of the positioning frame 31 on the repair frames 33.

[0055] During the actual use process, after the U-shaped frame 1 is fixed on the steel pipe tower, move the welding module 4 upward. The clamping unit 35 connects the positioning frame 31 and the welding module 4 together. At this time, the upper and lower end faces of the angle steel are respectively in close contact with the positioning frame 31 and the welding module 4. Then shake the moving unit 34 so that the positioning frame 31 can move left and right reciprocally on the first slide rail 32, thereby realizing the repair function of the repair frame 33 for the bent part of the angle steel. After the repair is completed, the welding module 4 welds and reinforces the angle steel.

[0056] It should be noted that when repairing the angle steel, the moving unit 34 can drive the repair frame 33 to perform extrusion and rolling repair on the bent part of the angle steel, which is beneficial to the full repair of the angle steel.

[0057] Refer to Figure 2 , Figure 4 andFigures 6-8 , in order to reinforce the repaired angle steel, a welding module 4 is provided in this embodiment. The welding module 4 includes a triangular mold frame 41, a welding unit 42, a material storage unit 43, and a lifting unit 44. The lower end of the middle part of the U-shaped frame 1 is provided with a lifting unit 44, and a material storage unit 43 is installed on the lifting unit 44. The material storage unit 43 is clamped with the clamping unit 35. A triangular mold frame 41 is installed on the material storage unit 43. The triangular mold frame 41 is made of hard material. A triangular through groove is provided in the triangular mold frame 41, and a welding unit 42 is installed in the triangular through groove.

[0058] During the actual use process, the lifting unit 44 drives the triangular mold frame 41 and the material storage unit 43 to move upward, so that the angle steel is located between the triangular mold frame 41 and the repair frame 33, and at this time, the angle steel is in close contact with the triangular mold frame 41 and the repair frame 33. Through the mutual rolling extrusion of the triangular mold frame 41 and the repair frame 33 on the bent part of the angle steel, the bent part of the angle steel can be successfully repaired. Subsequently, the material storage unit 43 pushes the reinforcement plates 5 upward one by one, and the welding unit 42 applies flux to the reinforcement plates 5 and performs welding, so that the reinforcement plates 5 can be bonded to the angle steel, realizing the reinforcement function of the repaired angle steel.

[0059] Refer to Figure 9 and Figure 10 , a repair groove is provided on the repair frame 33, and repair shafts 331 are evenly installed on the side wall of the repair groove. The surface of the repair shaft 331 is smooth, the repair shaft 331 is made of hard material, and the end face of the repair shaft 331 is in close contact with the angle steel.

[0060] During the actual use process, when repairing the bent part of the angle steel, by driving the left and right movement of the positioning frame 31 through the moving unit 34, the repair shafts 331 evenly installed on the side wall of the repair groove can roll and repair the bent part of the angle steel, so that the repair is more thorough.

[0061] Refer to Figure 2 , Figure 3 , Figure 9 and Figure 10 , in order to continuously repair and reinforce the bent angle steel, a moving unit 34 is provided in this embodiment. The moving unit 34 includes a threaded column 341, a fixed frame 342, an annular gear 343, a bevel gear 344, a rotating shaft 345, and a rotating handle 346. The ends of the U-shaped frame 1 are symmetrically installed with fixed frames 342 by screws. The inside of the fixed frame 342 is a hollow structure. A threaded column 341 is installed between the fixed frames 342 through bearings. A threaded hole matching the threaded column 341 is provided on the positioning frame 31. An annular gear 343 is installed at the end of the threaded column 341. A rotating shaft 345 is installed in the fixed frame 342 through bearings. A bevel gear 344 is installed at the front end of the rotating shaft 345. The bevel gear 344 meshes with the annular gear 343. A rotating handle 346 is installed at the rear end of the rotating shaft 345.

[0062] During actual use, when repairing the angle steel, the rotating handle 346 is shaken, the annular gear 343 is combined with the bevel gear 344, thereby driving the threaded column 341 to rotate. The threaded column 341 drives the positioning frame 31 to reciprocate above the angle steel, and the repair frame 33 thus performs rolling extrusion repair on the bent part of the angle steel, which is beneficial to the full repair of the angle steel.

[0063] Refer to Figure 5 In order to be able to connect the positioning frame 31 with the welding module 4, a clamping unit 35 is provided in this embodiment. The clamping unit 35 includes a connecting plate 351, a locking plate 352 and a locking screw 353. The lower end of the positioning frame 31 is evenly provided with connecting plates 351. The connecting plate 351 has a rectangular structure. An empty groove is provided on the connecting plate 351. A locking plate 352 is slidably arranged in the empty groove. The locking plate 352 has a rectangular structure. A locking screw 353 is installed on the side wall of the connecting plate 351, and the locking screw 353 is connected with the locking plate 352.

[0064] During actual use, when the lifting unit 44 drives the welding module 4 to move below the positioning frame 31, the connecting plate 351 is clamped with the welding module 4. After that, the locking plate 352 is pushed outwards, and then the locking screw 353 is screwed to connect the locking plate 352 with the welding module 4, thereby realizing the clamping function of the positioning frame 31 and the welding module 4, which is beneficial to the synchronous movement of the positioning frame 31 and the welding module 4, and further fully repairs the angle steel.

[0065] Refer to Figure 6 and Figure 7 The welding unit 42 includes a telescopic cylinder 421, a triangular frame 422, a moving frame 423, a spring 424, a telescopic plate 425 and a welding head 426. The triangular frame 422 is installed on the right side inside the triangular through groove. An inclined groove is provided in the triangular frame 422. A moving frame 423 is slidably arranged in the inclined groove. A telescopic cylinder 421 is installed on the inner wall of the triangular through groove, and the telescopic cylinder 421 is connected with the moving frame 423. A telescopic groove is provided on the moving frame 423. A telescopic plate 425 is slidably arranged in the telescopic groove. An inclined surface in close contact with the inclined groove is provided at the upper end of the telescopic plate 425. A spring 424 is installed between the lower end of the telescopic plate 425 and the telescopic groove. Triangular plates are evenly installed on the outer side of the telescopic plate 425, and welding heads 426 are installed on the triangular plates. The welding heads 426 are arranged obliquely.

[0066] During the actual use process, after the angle steel is repaired, the stock storage unit 43 pushes the reinforcement plate 5 upwards, making the reinforcement plate 5 closely adhere to the inner wall of the angle steel. Then, the first telescopic cylinder 421 is activated. The first telescopic cylinder 421 drives the moving frame 423 to move to the right, and the telescopic plate 425 gradually extends out of the telescopic groove, thereby driving the welding head 426 to move to the gap between the angle steel and the reinforcement plate 5. The welding head 426 can achieve the function of accurately welding and fixing between the angle steel and the reinforcement plate 5. After welding, the first telescopic cylinder 421 first drives the moving frame 423 to move to the left, thereby retracting the welding head 426 into the triangular die holder 41, thus realizing the function of strengthening the angle steel.

[0067] It should be noted that when the telescopic plate 425 contracts into the telescopic groove, the first spring 424 is always in a compressed state; when the first telescopic cylinder 421 pushes the triangular frame 422 to the right, the first spring 424 resets, and the telescopic plate 425 extends out of the telescopic groove, thereby realizing the function of gradually pushing the welding head 426 outwards.

[0068] Refer to Figure 6 and Figure 8 For the purpose of storing the reinforcement plate 5, a stock storage unit 43 is provided in this embodiment. The stock storage unit 43 includes a stock storage rack 431, a feeding mechanism 432, a pushing mechanism 433, and a storage battery 434. The stock storage rack 431 is installed on the lifting unit 44. The stock storage rack 431 is provided with a rectangular groove that cooperates with the connecting plate 351. The inner wall of the rectangular groove is provided with a through groove that cooperates with the locking plate 352. A rectangular opening is provided on the right side of the upper end of the stock storage rack 431. The stock storage rack 431 is a hollow structure. The feeding mechanism 432 is installed above the interior of the stock storage rack 431, the storage battery 434 is installed below the interior of the stock storage rack 431, and the pushing mechanism 433 is installed at the right end of the interior of the stock storage rack 431.

[0069] During the actual use process, after the angle steel is repaired, the pushing mechanism 433 pushes the reinforcement plate 5 stored in the feeding mechanism 432 upwards through the rectangular opening, thereby welding the surface of the reinforcement plate 5.

[0070] It should be noted that the storage battery 434 can supply power to the feeding mechanism 432, the pushing mechanism 433, and the welding head.

[0071] Refer to Figure 2 、 Figure 4 and Figure 9In order to realize the lifting function of the welding module 4, a lifting unit 44 is provided in this embodiment, and the lifting unit 44 includes a mounting frame 441, a second slide rail 442 and a telescopic rod 443. The mounting frame 441 is slidably provided at the upper end of the middle part of the U-shaped frame 1. The mounting frame 441 has a U-shaped structure, and the telescopic rods 443 are evenly installed at the lower end of the mounting frame 441. A cylindrical through groove is symmetrically provided at the lower middle part of the storage rack 431, and a second slide rail 442 is slidably provided in the cylindrical through groove, and the end of the second slide rail 442 is connected to the side wall of the mounting frame 441.

[0072] During actual use, when the positioning frame 31 stays just above the bend of the angle steel, pull the mounting frame 441 upward, and at the same time adjust the mounting frame 441 to slide left and right on the slide rail 2 442, so that the storage rack 431 can be engaged with the positioning frame 31, thereby achieving accurate repair of the bend of the angle steel.

[0073] It should be noted that, during the upward movement of the mounting frame 441 , the telescopic rod 443 can prevent the mounting frame 441 from shaking left and right, thereby accurately positioning the bend of the angle steel.

[0074] Reference Figure 6 and Figure 8 In order to realize the feeding function of the reinforcement plate 5, a feeding mechanism 432 is provided in the present embodiment, and the feeding mechanism 432 includes a connecting frame 4321, a feeding frame 4322, a second spring 4323 and a pushing plate 4324. The feeding frame 4322 is installed above the middle part of the storage frame 431, and the feeding frame 4322 is L-shaped. The second spring 4323 is installed on the inner wall of the feeding frame 4322, and the end of the second spring 4323 is connected to the pushing plate 4324. The reinforcement plates 5 are evenly placed on the feeding frame 4322, and the pushing plate 4324 is always in close contact with the reinforcement plate 5. The reinforcement plate 5 is made of iron. Slide grooves are symmetrically provided on the inner wall of the storage frame 431, and the pushing plate 4324 slides in the slide groove. The connecting frame 4321 is installed on the outer end of the feeding frame 4322.

[0075] During actual use, when the diagonal steel is repaired, the pushing plate 4324 pushes the reinforcement plate 5 one by one into the pushing mechanism 433, and only one reinforcement plate 5 can be placed in the pushing mechanism 433. Then the pushing mechanism 433 drives the reinforcement plate 5 to push upward through the rectangular opening, which is conducive to welding the reinforcement plate 5. At this time, the lower end of the pushing mechanism 433 blocks the right end of the feeding rack 4322 to prevent the reinforcement plate 5 from falling from the end of the feeding rack 4322.

[0076] It should be noted that the end of the connecting frame 4321 is located at the outer end of the storage rack 431 , and the reinforcing plate 5 can be added to the feeding rack 4322 regularly by pulling out the connecting frame 4321 .

[0077] It should also be noted that when the reinforcement plate 5 is placed in the feeding rack 4322, the second spring 4323 is always in a compressed state, which is beneficial to the pushing and feeding of the reinforcement plate 5.

[0078] Referring to Figure 6 and Figure 8 In order to realize the pushing function of the reinforcement plate 5, a pushing mechanism 433 is provided in this embodiment. The pushing mechanism 433 includes an L-shaped frame 4331, a magnet 4332, a baffle 4333 and a second telescopic cylinder 4334. The second telescopic cylinder 4334 is installed at the lower right end of the middle part of the storage rack 431. The end of the second telescopic cylinder 4334 is connected with the L-shaped frame 4331. Magnets 4332 are symmetrically installed on the inner wall of the L-shaped frame 4331, and a baffle 4333 is installed at the lower end of the L-shaped frame 4331.

[0079] During actual use, after the angle steel is repaired, the second telescopic cylinder 4334 is started. The second telescopic cylinder 4334 drives the L-shaped frame 4331 and the reinforcement plate 5 to move upward. At this time, the magnets 4332 symmetrically installed on the inner wall of the L-shaped frame 4331 tightly adsorb the reinforcement plate 5 to prevent the reinforcement plate 5 from falling during upward movement and welding; when the L-shaped frame 4331 drives the reinforcement plate 5 to move to the upper end of the storage rack 431, the baffle 4333 blocks the right end of the feeding rack 4322 to prevent the reinforcement plate 5 stored in the feeding rack 4322 from falling; after the welding of the reinforcement plate 5 is completed, the second telescopic cylinder 4334 is started. The second telescopic cylinder 4334 drives the L-shaped frame 4331 to move downward. At this time, the pushing plate 4324 pushes the reinforcement plate 5 into the L-shaped frame 4331 again, which is beneficial to the function of pushing out the reinforcement plates 5 one by one.

[0080] The implementation principle of this embodiment is as follows:

[0081] 1: Fix the U-shaped frame. When repairing the bent angle steel, first adjust the position of the sliding plate 22 so that the connecting block 24 can be stuck on the steel pipe tower. Then connect the clamping block 25 to the end of the connecting block 24 and connect the connecting block 24 and the clamping block 25 together with screws, so that the U-shaped frame 1 can be fixed on the steel pipe tower.

[0082] 2: Locate the bent part of the angle steel. After the U-shaped frame 1 is fixed on the steel pipe tower, move the welding module 4 upward. The clamping unit 35 connects the positioning frame 31 and the welding module 4 together. At this time, the upper and lower end faces of the angle steel are respectively in close contact with the positioning frame 31 and the welding module 4. Then shake the moving unit 34 so that the positioning frame 31 can move left and right reciprocally on the first slide rail 32, so as to realize the repair function of the repair frame 33 for the bent part of the angle steel.

[0083] 3: Repair and reinforce the bent part of the angle steel. After the angle steel is repaired, the storage unit 43 pushes the reinforcement plate 5 upward so that the reinforcement plate 5 is closely attached to the inner wall of the angle steel. Start the first telescopic cylinder 421. The first telescopic cylinder 421 drives the moving frame 423 to move to the right, and the telescopic plate 425 gradually extends from the telescopic groove, thereby driving the welding head 426 to move to the gap between the angle steel and the reinforcement plate 5. The welding head 426 can achieve the function of accurately welding and fixing between the angle steel and the reinforcement plate 5. After welding, the first telescopic cylinder 421 first drives the moving frame 423 to move to the left, so as to retract the welding head 426 into the triangular die holder 41, thus realizing the function of reinforcing the angle steel.

Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
