Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment for iron tower steel frames, and particularly relates to a welding and conveying device for processing large iron tower steel frames. Background Art

[0002] With the development of the times and the progress of informatization, the construction of communication and power transmission towers has been gradually improved at present. During the construction of transmission towers, steel structures are used for erection, and thus it is necessary to weld and assemble steel frames. When welding the steel frames of some large transmission towers, it is necessary to weld ear plates and bases on circular steel pipes. During the welding process, it is necessary to weld and convey the steel pipes to be welded. The patent with the Chinese patent publication number CN113478135B discloses a welding and conveying assembly for processing giant iron tower steel frames, including a base. A conveying structure is arranged on the base. A lifting structure is arranged at one end of the base. A fixing structure is arranged on the lifting structure. A jacking structure is installed on the base. A pressing structure is installed on the base. A rotating structure is installed on the base. A lifting structure is installed on the rotating structure. A driving structure is arranged at one end of the lifting structure. It has the advantages that when it is necessary to rotate and weld the conveyed steel pipe, the steel pipe can be jacked up and rotated to facilitate the rotation welding. At the same time, when the jacking structure performs the jacking action, it can also drive the pressing structure to work synchronously. Through the work of the pressing structure, while the steel pipe is jacked up, the outside of the steel pipe can be laterally pressed.

[0003] In the above-mentioned prior art, during the welding and conveying process of steel pipes, the steel pipes are usually placed on a conveyor belt formed by rotating rollers, and the steel pipes are conveyed to the welding working end for welding by driving the rotation of multiple groups of rotating rollers by a motor. After welding, they are conveyed away. During this process, since irregular ear plates and connecting plates need to be welded on the outer diameter of the steel pipe when welding the iron tower steel frame to facilitate the subsequent splicing and welding process, when the welded steel pipe is conveyed through the rotating rollers or the conveyor belt again, its irregular shape has the risk of getting stuck or falling on the rotating rollers or the conveyor belt, and it is not safe enough to use. In addition, during the welding process, the conveyor belt needs to stop, and the subsequent steel pipes cannot be conveyed, so continuous conveying cannot be achieved, and it is not convenient enough to use. For this reason, a welding and conveying device for processing large iron tower steel frames is proposed. Summary of the Invention

[0004] In order to solve the problems that when the welded steel pipe is conveyed through the rotating rollers or the conveyor belt again, its irregular shape has the risk of getting stuck or falling on the rotating rollers or the conveyor belt, and it is not safe enough to use. In addition, during the welding process, the conveyor belt needs to stop, and the subsequent steel pipes cannot be conveyed, so continuous conveying cannot be achieved, and it is not convenient enough to use, the present invention provides a welding and conveying device for processing large iron tower steel frames.

[0005] The present invention specifically adopts the following technical solutions to achieve the above object:

[0006] A welding and conveying device for processing large-scale iron tower steel frames, including a guide rail. A double-layer sliding disk is slidably installed on the guide rail. A traveling mechanism for conveying steel frame steel pipes is installed on the double-layer sliding disk. A transmission mechanism for driving the traveling mechanisms on both sides of the guide rail to move is installed on the double-layer sliding disk. A deflection mechanism for deflecting the steel frame steel pipes during conveying is installed on the double-layer sliding disk. A rotating mechanism for rotating the steel frame steel pipes is installed on the deflection mechanism. A clamping mechanism for contacting the inner diameters of steel frame steel pipes of different sizes is installed on the rotating mechanism. An adjusting mechanism for driving the clamping mechanisms in different directions to move is installed on the rotating mechanism. The adjusting mechanism is located on the top side of the clamping mechanism. When welding and conveying the steel pipe, after placing the steel pipe on the rotating mechanism, start the adjusting mechanism. The adjusting mechanism moves to drive the clamping mechanisms in different directions to move simultaneously, thereby clamping the steel pipes with different inner diameters, facilitating the maintenance of the stability of the steel pipes during conveying, increasing the use safety of the conveying equipment. After clamping, start the transmission mechanism. The transmission mechanism moves to drive the traveling mechanisms on both sides of the guide rail to move simultaneously, thereby driving the steel pipe to move on the guide rail to the bottom side of the welding working end, facilitating the welding process and the subsequent steel pipe conveying process, improving the use convenience of the equipment. And during this process, through the setting of the deflection mechanism, it is convenient to adjust the position of the steel pipe longitudinally during the welding process, facilitating the welding of the ear plates and the subsequent conveying process, and further improving the use convenience of the structure.

[0007] Further, the traveling mechanism includes a connecting ear plate. The connecting ear plate is installed on the double-layer sliding disk. A driven wheel is rotatably installed on the connecting ear plate. A gear roller is installed on the driven wheel. Continuous tooth grooves are formed on the guide rail. The gear roller meshes with the continuous tooth grooves. A driving wheel is rotatably installed on the double-layer sliding disk. The driving wheel and the driven wheel are engaged with the same chain. When the driving wheel rotates, it drives the chain to move. The chain movement drives the driven wheel to rotate. The driven wheel rotation drives the gear roller to rotate. During the rotation of the gear roller, it is restricted by the continuous tooth grooves, realizing the sliding of the double-layer sliding disk on the guide rail, thereby realizing the traveling function and facilitating the conveying of the steel pipe.

[0008] Further, the transmission mechanism includes a fixed seat. The fixed seat is installed on the double-layer sliding disk. A worm is rotatably installed on the fixed seat. A worm gear is installed on the driving wheel. The worm gear meshes with the worm. A motor is installed on the fixed seat. The main shaft of the motor is installed on the worm. Start the motor. The motor rotation drives the worm to rotate on the fixed seat. The worm rotation drives the worm gears on both sides to rotate in opposite directions respectively, thereby driving the driven wheels on both sides to move in opposite directions.

[0009] Further, the deflection mechanism includes a chassis, which is installed on a double-layer sliding plate. The chassis is located on the top side of the fixed seat. A rotating shaft is rotatably installed on the chassis, and a rotating seat is installed on the rotating shaft. A deflection motor is installed on the chassis, and the main shaft of the deflection motor is installed on the rotating shaft. When the deflection motor is started, the deflection motor rotates to drive the rotating shaft to rotate, and the rotating shaft rotates to drive the rotating seat to rotate. The rotation of the rotating seat can drive the steel pipe being conveyed or welded to deflect longitudinally, facilitating the welding and conveying processes and improving the convenience of equipment use.

[0010] Further, the rotation mechanism includes a connecting rotating shaft, which is rotatably installed on the rotating seat. A rotating chassis is installed on the connecting rotating shaft, a connecting roller is installed on the rotating chassis, and a rotating top plate is installed on the connecting roller. A rotating motor is installed on the rotating seat, and the main shaft of the rotating motor is installed on the connecting rotating shaft. When the rotating motor is started, the rotating motor rotates to drive the connecting rotating shaft to rotate, and the connecting rotating shaft rotates to drive the rotating chassis and the rotating top plate to rotate, thereby realizing the rotation of the steel pipe being conveyed or welded in the horizontal direction, facilitating the welding process, and further improving the convenience of equipment use.

[0011] Further, the clamping mechanism includes a threaded rod. One end of the threaded rod is rotatably installed on the rotating chassis, and the other end of the threaded rod is rotatably installed on the rotating top plate. A sliding seat is threadedly installed on the threaded rod, and a threaded hole is formed in the sliding seat. The threaded rod is threadedly installed in the threaded hole. A connecting rotating plate is rotatably installed on the sliding seat, a common plate is rotatably installed on the connecting rotating plate, a connecting rod is installed on the common plate, and an arc end plate is installed on the connecting rod. When the threaded rod rotates, it drives the sliding seat to slide in the direction of approaching or separating from each other, thereby driving the connecting rotating plate to rotate on the sliding seat and the common plate, causing the arc end plate on the common plate to slide closer to or away from the connecting roller, thus facilitating the clamping of steel pipes with different inner diameters and improving the wide applicability and convenience of use of the structure.

[0012] Further, the adjustment mechanism includes a mounting frame, which is installed on the rotating top plate. A gear disc is rotatably installed on the mounting frame, an adapter gear is installed on the threaded rod, and the adapter gear meshes with the gear disc. An adjustment motor is installed on the mounting frame, and the main shaft of the adjustment motor is installed on the gear disc. When the adjustment motor is started, the adjustment motor rotates to drive the gear disc on the mounting frame to rotate, and the gear disc rotates to drive the adapter gears in different directions to rotate in the same direction at the same time, thereby causing the threaded rods in different directions to rotate in the same direction, facilitating the clamping and fixing of the steel pipe from different directions at the same time, and further improving the automation level and convenience of use of the structure.

[0013] Furthermore, a T-shaped slider is installed on the double-layer sliding plate, and a T-shaped sliding groove is formed on the guide rail. The T-shaped slider is slidably installed in the T-shaped sliding groove. Through the arrangement of the T-shaped sliding groove, the movement of the T-shaped slider is restricted. The T-shaped slider can only slide in the T-shaped sliding groove, so that the double-layer sliding plate can only slide on the guide rail, further increasing the stability of the steel pipe welding and conveying.

[0014] The beneficial effects of the present invention are as follows:

[0015] In the present invention, through the arrangement of the gear roller, the driving wheel, the chain, the chassis, the rotating shaft, the rotating seat, etc., it is realized that during the process of welding and conveying the steel pipes of the iron tower steel frame, the rotation of the gear roller drives the individual steel pipes to be conveyed on the guide rail, so that the subsequent steel pipe conveying is not affected during the welding process, improving the conveying speed and the convenience of use of the equipment. And through the arrangement of the rotating seat, it is convenient to deflect the steel pipe longitudinally to prevent the irregular shape after welding from affecting the conveying, further improving the convenience of use of the equipment.

[0016] In the present invention, through the arrangement of the connecting rotating shaft, the rotating chassis, and the rotating top plate, the rotation of the steel pipe during conveying or welding in the horizontal direction is realized, facilitating the welding process and further improving the convenience of use of the equipment.

[0017] In the present invention, through the arrangement of the threaded rod, the sliding seat, the arc end plate, etc., when the threaded rod rotates, the sliding seat is driven to slide in the direction of approaching or separating from each other at the same time, thereby driving the connecting rotating plate to rotate on the sliding seat and the common plate, so that the arc end plate on the common plate slides close to or away from the connecting roller, thus facilitating the clamping of steel pipes with different inner diameters, improving the wide applicability and the convenience of use of the structure.

[0018] In the present invention, through the arrangement of the mounting frame, the mating gear, the gear disc, etc., it is convenient to clamp and fix the steel pipe from different directions at the same time, further improving the automation degree and the convenience of use of the structure.
