Description

Technical Field

[0001] The invention relates to the technical field of power tower foot welding, and in particular to an integrated power tower foot welding workstation. Background Art

[0002] The power tower is a tower-shaped building used for power transmission. The tower mainly consists of a tower body, a tower foot, and a tower base. The tower foot is a welded assembly made of several steel plates. The tower foot is the main supporting component of the entire power transmission tower structure, including a bottom plate, a main plate, a first side plate, and a second side plate. The main plate is vertically welded and fixed in the middle of the bottom plate. The first side plate and the second side plate are located on both sides of the main plate. The first side plate is vertically welded and fixed to the main plate and the bottom plate. The second side plate is also vertically welded and fixed to the main plate and the bottom plate. The main plate, the first side plate, and the second side plate are all provided with a number of tower body connection holes for connecting to the main material of the tower body. The four corners of the bottom plate are provided with reserved holes for connecting to the embedded base.

[0003] Chinese patent CN202411441608.8 discloses an integrated power tower foot welding workstation, including a welding robot; a clamping assembly for clamping the tower foot, close to the welding robot; a hoisting assembly for lifting the tower foot, including a gantry, a slide, a hydraulic rod and a sling; the slide is arranged horizontally; the two ends of the gantry are respectively connected to the slide; the slide drives the top of the gantry to move above the clamping assembly; one end of the hydraulic rod is connected to the top of the gantry, and the other end is connected to the sling; the hydraulic rod is vertically distributed; and a control system connected to the welding robot, the hydraulic rod and the slide circuit. The hydraulic rod goes straight up and down, and there is no deflection or shaking, and the stability is high, which effectively prevents the tower foot from shifting during the lifting process. At the same time, the tower foot can be clamped by hoisting it to the cross slot during work, without adjusting the position of the tower foot, reducing the adjustment time.

[0004] However, this technical solution has certain drawbacks when used. The method of hoisting the tower foot plate by the gantry and the hoist before welding requires multiple disassembly and assembly of the hoist. The steps are cumbersome and the production efficiency is low, and the welding effect is difficult to guarantee. Summary of the invention

[0017] The beneficial effects of the present invention are as follows:

[0018] (1) When the positioning base plate is in the initial position, the present invention drives the push plate a through the cylinder a to push the bottom base plate from the material discharge slope to the positioning ring of the positioning base plate, and drives the cross plate to move through the inclined material guide of the material guide slope and the rotation of the guide roller, and is discharged from the cross material discharge pipe and falls into the positioning ring of the positioning base plate to realize the sequential loading of the base plate and the cross plate, so that the cross plate is above the base plate, and is preliminarily positioned and assembled through the positioning ring, which is convenient for loading while ensuring the assembly effect between the plates, and drives the active shaft to rotate through the motor a, and realizes the movement of the two groups of conveyor belts through the guidance of the driven shaft and multiple groups of guide wheels, and further realizes the transportation and loading of the two groups of plates on the positioning base plate to the welding station. While having high stability, continuous operation can be realized by driving the conveyor belt in the positive direction, reducing cumbersome processes and improving production efficiency.

[0019] (2) The present invention uses a positioning ring on the positioning base plate and two sets of electric telescopic rods to push the clamping block to clamp and fix the cross plate, thereby ensuring the stability of the plates during transportation and subsequent processing.

[0020] (3) During the transportation process, the present invention starts the motor b to drive the screw to rotate, and through the threaded connection between the slider and the nut and the screw and the limiting guidance of the lower track, the upper processing component can be moved over a large range when the motor b rotates forward and reverse. The cylinder b drives the output of the bottom ring and the upper processing component to further move finely, so that the processing component on the bottom ring is in close contact with the right-angle groove of the cross plate to ensure the subsequent processing effect. At the same time, the four groups of subsequent processing structures are moved to fit closely at the four right angles of the two groups of plates to further support the plates and ensure the stability between the plates.

[0021] (4) During the transportation process, the present invention drives the four groups of motors c and the belts between the two groups of wheels to realize the rotation of the rollers. The friction force drives the tough belt and the sandpaper belt to move stably along the guide ring. When in right-angle contact with the cross plate, the right-angle welding part of the plate is fully rubbed. The oxide layer and rust on the surface of the plate are removed by friction, thereby improving the welding effect and enhancing the adhesion effect of the coating agent. The tough belt can pass through the gap generated by the spring connection between the square electromagnet and the metal pressure plate in the sandpaper groove, and when the square electromagnet is energized to generate a strong magnetic force, the metal pressure plate can be tightly adsorbed through the sandpaper belt to achieve the compression and fixation of the sandpaper belt, so as to realize the installation of the sandpaper belt. This installation method is convenient for users to replace the sandpaper belt.

[0022] (5) During the transportation process of the present invention, a quantitative coating agent is injected into the V-shaped diversion pipe through a pump machine and a liquid injection pipe. After being diverted by the V-shaped diversion pipe, it overflows from multiple liquid outlet holes on the V-shaped seat onto the V-shaped sponge strip to replenish the coating agent for the V-shaped sponge strip. The roller contacts the inner wall of the flexible belt. When it moves, the worm on the roller can be driven to rotate through friction. The meshing of the worm gear and the worm will drive the worm and the cam to rotate. Through the movable connection between the connecting rod on the cam and the movable block on the movable rod, the movable rod can be driven to reciprocate and stretch along the slide rail when the cam rotates, so that the V-shaped sponge strip installed at the other end of the movable rod can reciprocally contact and squeeze the right-angle inner wall of the cross-shaped plate member. The coating agent in the V-shaped sponge strip is extruded through the extrusion method, and the extruded coating agent will flow along the right-angle inner wall to the friction and welding area. While enhancing the welding and friction effects through the coating agent, the friction and welding can be cooled by continuously increasing the amount of the coating agent.

[0023] In summary, the present invention has the advantages of high efficiency and convenience. Description of the Drawings

[0068] In this embodiment, the liquid storage tank 365 is a coating agent storage unit, which injects a certain amount of coating agent into the V-shaped guide tube 367 through the pump 366 and the injection tube 368. After being guided by the V-shaped guide tube 367, the coating agent overflows from the multiple groups of lower liquid holes 369 on the V-shaped seat 363 to the V-shaped sponge strip 364 to replenish the V-shaped sponge strip 364 with coating agent.

[0069] The driving component 37 includes: a slide rail 371, with two groups of slide rails 371 arranged on both sides of the fixed seat 361; movable blocks 372, with multiple groups of movable blocks 372 fixedly connected to the outer side of the movable rod 362; block pin columns 3721, with the block pin columns 3721 arranged on the movable blocks 372; wheel seats 373, with two groups of wheel seats 373 arranged on both sides of the fixed seat 361; rollers 374, with the rollers 374 movably connected to the two groups of wheel seats 373; a worm 375, with the worm 375 arranged on the roller 374; a worm gear 376, with the worm gear 376 penetrating and connected to the fixed seat 361; cams 377, with two groups of cams 377 movably connected to the fixed seat 361; wheel pin columns 3771, with the wheel pin columns 3771 arranged on the cams 377; a connecting rod 378, with the connecting rod 378 movably connected to the cam 377; an activity groove 3781, with the activity groove 3781 opened on the connecting rod 378; a limit pin column 379, with the limit pin column 379 arranged on the fixed seat 361.

[0070] In this embodiment, the roller 374 contacts the inner wall of the resilient belt 342. When it moves, the worm 375 on the roller 374 can be driven to rotate through friction. The meshing of the worm gear 376 and the worm 375 will drive the worm 375 and the cam 377 to rotate. Through the movable connection between the connecting rod 378 on the cam 377 and the movable block 372 on the movable rod 362, the movable rod 362 can be driven to reciprocate and move telescopically along the slide rail 371 when the cam 377 rotates. As a result, the V-shaped sponge strip 364 in the V-shaped seat 363 installed at the other end of the movable rod 362 can reciprocally contact and squeeze the right-angle inner wall of the cross-shaped plate member 5. The coating agent in the V-shaped sponge strip 364 can be extruded through the squeezing method. The extruded coating agent will flow along the right-angle inner wall to the welding and friction areas. While enhancing the welding effect by squeezing and coating the coating agent, the friction treatment effect can be improved. Further, subsequent cooling treatment can be carried out for friction and welding.

[0071] Embodiment Three: As Figure 24 shown, where the same or corresponding components as in Embodiment One adopt the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The difference between this Embodiment Three and Embodiment One lies in:

[0072] A processing platform 6 is provided on the top of the base 1. A chassis 601 is provided at the bottom of the processing platform 6. Two groups of belt grooves 602 are opened on the top of the processing platform 6. A limiting edge 603 is provided on the top of the processing platform 6; A welding robot 7 is provided on one side of the processing platform 6. A movable fuel tank 8 is provided on one side of the welding robot 7.

[0073] In this embodiment, the two sets of grooves 602 extend the two sets of conveyor belts 208 to the processing platform 6. The frictional force of the conveyor belts 208 can transport the positioning base plate 301 to the designated welding station on the processing platform 6, and when the conveyor belts 208 are driven in reverse, the positioning base plate 301 can be moved out to the initial position on the transport mechanism 2, further realizing continuous processing. The welding robot 7 is an existing welding technology and will not be elaborated in this text. The movable fuel tank 8 provides fuel for it.

[0074] Working steps

[0075] Step 1, Sandpaper installation process: Pass the sandpaper belt through the gap generated by the connection between the ductile belt 342 and the metal pressing plate 354 through the spring 355 between the square electromagnet 353 in the sandpaper groove 343. Energize the square electromagnet 353. When it generates a strong magnetic force, it can tightly adsorb the metal pressing plate 354 through the sandpaper belt to realize the pressing and installation of the sandpaper belt.

[0076] Step 2, Loading process: Place the positioning base plate 301 at the initial position. Drive the push plate a214 through the cylinder a213 to push the bottommost bottom plate part 4 from the blanking slope 212 into the positioning ring 302 of the positioning base plate 301. Then, through the oblique guiding of the guiding slope 223 and the rotation of the guiding roller 224, drive the cross plate part 5 to move and discharge from the cross blanking pipe 222 and fall into the positioning ring 302 of the positioning base plate 301 to realize the sequential loading of the bottom plate part 4 and the cross plate part 5, so that the cross plate part 5 is above the bottom plate part 4, and preliminary positioning and assembly are carried out through the positioning ring 302.

[0077] Step 3, Positioning process: The two sets of electric telescopic rods 313 are energized and started. The output rods push the blocks 314 to approach the center, and clamp and fix the cross plate part 5 to ensure stability during transportation and subsequent processing.

[0078] Step 4, Transportation process: Drive the rotation of the driving shaft 205 through the motor a203, and realize the movement of the two sets of conveyor belts 208 through the guidance of the driven shaft 206 and multiple sets of guide wheels 207, and further transport and load the two sets of plates on the positioning base plate 301 to the welding station.

[0079] Step 5, Movement process: During transportation, start the motor b323 to drive the rotation of the lead screw 324. Through the threaded connection between the slider 325 and the lead screw 324 through the nut 326 and the limiting guidance of the lower track 322 below, realize the large-range movement of the upper processing component 34 when the motor b323 rotates forward and backward, and further finely move the output bottom ring 333 and the upper processing component 34 through the cylinder b332.

[0080] Step Six, Preparation Process: Move the processing component 34 to the right-angle inner wall near but not in contact with the bottom end of the cross-shaped plate member 5, then start the motor c347. Driven by the motor c347, the rotation of the roller 346 is achieved through the transmission of the belt 349 between the two sets of rollers 348. The toughness belt 342 is stably moved along the guide ring 344 by the frictional force. The roller 374 contacts the inner wall of the toughness belt 342, and when it moves, the worm 375 on the roller 374 can be driven to rotate by the frictional force. The meshing of the worm gear 376 and the worm 375 will drive the worm 375 and the cam 377 to rotate. Through the movable connection between the connecting rod 378 on the cam 377 and the movable block 372 on the movable rod 362, the movable rod 362 can be driven to reciprocally move and expand along the slide rail 371 when the cam 377 rotates, so that the V-shaped sponge strip 364 in the V-shaped seat 363 installed at the other end of the movable rod 362 can reciprocally contact and squeeze the right-angle inner wall of the cross-shaped plate member 5;

[0081] Inject a small amount of coating agent into the V-shaped diversion pipe 367 through the pump 366 and the liquid injection pipe 368. After being diverted by the V-shaped diversion pipe 367, it overflows from multiple lower liquid holes 369 on the V-shaped seat 363 onto the V-shaped sponge strip 364 to replenish the coating agent for the V-shaped sponge strip 364. A small amount of the coating agent in the V-shaped sponge strip 364 is extruded by the extrusion method, and the extruded small amount of coating agent will flow along the right-angle inner wall to the lower friction area to improve the friction efficiency;

[0082] Step Six, Processing Process: Repeat the above moving process to move the toughness belt 342 in the processing component 34 to closely adhere to the right-angle inner wall at the bottom end of the cross-shaped plate member 5. Driven by the motor c347, the toughness belt 342 and the sandpaper belt are rubbed along the right-angle bottom edge. The oxide layer and rust on the surface of the plate are removed by the rubbing method to improve the welding effect. At the same time, the four right angles of the cross-shaped plate member 5 can be supported to further ensure the stability during transportation;

[0083] Step Seven, Cooling Process: Continuously inject a large amount of coating agent into the V-shaped sponge strip 364 of the V-shaped seat 363 through the pump 366 and the liquid injection pipe 368;

[0084] The roller 374 drives the V-shaped sponge strip 364 in the V-shaped seat 363 to reciprocally contact and squeeze the right-angle inner wall of the cross-shaped plate member 5. A large amount of the coating agent in the V-shaped sponge strip 364 is extruded by the extrusion method, and the extruded coating agent will flow along the right-angle inner wall to the lower friction area, which can fully cool and lower the temperature of the friction area. At the same time, after the welding is completed, the welding area can be cooled in the same way;

[0085] Step Eight, Recycling Process: The robotic arm installed on the positioning base plate 301 can grasp the base plate member 4 and the cross plate member 5 simultaneously, so that the height of the base plate member 4 is at the gap between the V-shaped seat 363 and the resilient belt 342. Again, the four sets of sliding mechanisms 32 and the displacement assembly 33 are used to insert the bottom end of the corresponding coating assembly 36 into the corners of the base plate member 4 through the gap between the V-shaped seat 363 and the resilient belt 342 until the V-shaped sponge strip 364 contacts the welding joint of the base plate member 4 and the cross plate member 5. The excess cooling coating liquid is absorbed and recycled into the V-shaped sponge strip 364 by the repeated extrusion and water absorption of the V-shaped sponge strip 364, and the coating agent is recycled by the back-pumping of the pump 366. The recycled liquid is filtered by the filtering structure in the liquid storage tank 365 and then used in a cycle;

[0086] During the recycling process, the V-shaped sponge strip 364 can contact the surface of the base plate member 4 during movement, and thus can push the coating liquid staying on the base plate member 4. Gathering the coating agent can reduce losses and evenly apply the coating liquid on the base plate member 4, so that the welding joints of the base plate member 4 and the cross plate member 5 can be coated;

[0087] Step Nine, Welding Process: The transportation mechanism 2 is used to move the two processed and coated plates and the positioning base plate 301 to the processing platform 6, and the welding robot 7 is used to weld the welding joints of the two plates.

[0088] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
