[0002] Power towers generally refer to transmission line towers. Transmission line towers are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers are spatial truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel. Therefore, during the production of power towers, the tower angle iron components need to be welded. Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic waves. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space.

[0023] It should be noted that the user can start the adjustment motor 65 to make the adjustment worm 62 drive the adjustment worm wheel 64 to rotate.

The side wall of the driven wheel 85 is provided with an arc groove 851, and a movable rod 86 is slidably mounted on the side wall of the inner cavity of the arc groove 851. The inner side wall of the mounting seat 5 is provided with a sliding groove 51, and a sliding sleeve 87 is slidably mounted in the inner cavity of the sliding groove 51. A sliding column 88 is slidably mounted in the inner cavity of the sliding sleeve 87. A clamping plate 89 is fixedly mounted on the side wall of the sliding column 88; The movable rod 86 is fixedly mounted on the side wall of the sliding sleeve 87 and slides in the inner cavity of the sliding groove 51. There are 6 groups of arc grooves 851 and the sliding grooves 51 equidistantly arranged. The arc grooves 851 are arranged in an arc shape, and the sliding grooves 51 are arranged in a straight bar shape.

[0027] It should be noted that the user can start the clamping motor 81 to rotate the extension rod 82, which is fixedly connected to the driving wheel 83 through the extension rod 82, and the driving wheel 83 is meshed with the driven wheel 85. At this time, the driving wheel 83 will drive the driven wheel 85 to rotate, and through the multiple groups of arc grooves 851 opened on the side wall of the driven wheel 85, under the limit constraint of the sliding groove 51 on the movable rod 86, the movable rod 86 will drive the sliding sleeve 87 to move toward the outside of the inner cavity of the sliding groove 51. At this time, the sliding sleeve 87 can drive the sliding column 88 to move the clamping plate 89 outward, so that the spacing between the multiple groups of clamping plates 89 changes, so as to realize the function of clamping the tubular iron tower component from the inside.

[0028] Furthermore, the blowing mechanism 9 includes a piston plate 91 slidably mounted in the inner cavity of the sliding sleeve 87. The piston plate 91 is fixedly mounted on the lower end surface of the sliding column 88. A return spring 92 is wound around the side wall of the sliding column 88. One end of the return spring 92 is fixedly mounted on the side wall of the piston plate 91, and the other end is fixedly mounted on the inner wall of the sliding sleeve 87. An air nozzle 93 is fixedly mounted on the side wall of the clamping plate 89. An air inlet 871 is provided at the lower portion of the side wall of the sliding sleeve 87. The inner cavity of the air inlet 871 is provided with a one-way air valve whose outlet is toward the inner cavity of the sliding sleeve 87. The inner cavity of the sliding column 88 is provided with an air outlet channel 881. The sliding column 88 is connected to the air nozzle 93 through the air outlet channel 881 and the clamping plate 89. The inner cavity of the air outlet channel 881 is provided with a one-way air valve whose outlet is toward the air nozzle 93. An air outlet 882 connected to the air outlet channel 881 is provided on the side wall of the sliding column 88.

[0029] It should be noted that as the clamping plate 89 is continuously pressed against the inner wall of the tubular iron tower component, the clamping plate 89 will squeeze the sliding column 88 to make the piston plate 91 move in the inner cavity of the sliding sleeve 87. At this time, the pressure in the upper cavity of the sliding sleeve 87 is continuously increasing, and the outside air can enter the inner cavity of the sliding sleeve 87 through the air inlet 871 to achieve the balance of the air pressure. At this time, the reset spring 92 is in a compressed state. After the tubular iron tower component is well welded, the user can start the clamping motor 81 to run in the reverse direction. At this time, under the elastic force of the reset spring 92, the clamping plate 89 will drive the sliding column 88 to move the piston plate 91 toward the outside of the inner cavity of the sliding sleeve 87. At this time, the volume of the upper cavity of the sliding sleeve 87 continues to decrease, and the internal air pressure continues to increase. Finally, the air in the sliding sleeve 87 can enter the inner cavity of the clamping plate 89 through the air outlet 882 and the air outlet channel 881, and finally high-pressure gas is ejected from the air nozzle 93 to accelerate the flow of air inside the tubular iron tower component, thereby realizing the function of cooling the tubular iron tower component that has just been welded, and further improving the efficiency of the entire device in welding the tubular iron tower component.

[0030] Working principle: During operation, the user can start the clamping motor 81 to rotate the extension rod 82, which is fixedly connected to the driving wheel 83 through the extension rod 82, and the driving wheel 83 is meshed with the driven wheel 85. At this time, the driving wheel 83 will drive the driven wheel 85 to rotate. Through the multiple groups of arc grooves 851 provided on the side wall of the driven wheel 85, under the limit constraint of the sliding groove 51 on the movable rod 86, the movable rod 86 will drive the sliding sleeve 87 to move toward the outside of the inner cavity of the sliding groove 51. At this time, the sliding sleeve 87 can drive the sliding column 88 to move the clamping plate 89 outward, so that the spacing between the multiple groups of clamping plates 89 changes, thereby realizing the function of clamping the tubular iron tower component from the inside; However, as the clamping plate 89 is continuously pressed against the inner wall of the tubular iron tower member, the clamping plate 89 will squeeze the sliding column 88, causing the piston plate 91 to move in the inner cavity of the sliding sleeve 87. At this time, the pressure in the upper cavity of the sliding sleeve 87 continues to increase, and external air can enter the inner cavity of the sliding sleeve 87 through the air inlet 871 to achieve air pressure balance. At this time, the return spring 92 is in a compressed state. When the tubular iron tower components are clamped and fixed on the mounting seats 5 on both sides, the user can start the adjustment motor 65 to operate, so that the adjustment worm 62 drives the adjustment worm gear 64 to rotate. Since the adjustment worm gear 64 is fixedly connected to the support rod 63, the support rod 63 can drive the adjustment gear 66 to rotate, and the adjustment rack 67 is meshed with the adjustment gear 66. The two adjustment racks 67 are respectively located on the front and rear sides of the adjustment gear 66. Under the limiting constraint of the limit rod 3 on the support seat 4, the adjustment racks 67 on the left and right sides can drive the support seats 4 to move closer to each other, so that the tubular iron tower components on the left and right sides are close to each other and are in a coaxial state. At this time, the user can start the welding machine 11 to realize the function of welding the connection of the tubular iron tower components. While welding the tubular iron tower component, the user can start the rotating motor 75 to drive the rotating worm 72 to drive the rotating worm wheel 74 to rotate. The rotating worm wheel 74 is fixedly connected to the connecting rod 73. At this time, the mounting seat 5 fixedly installed on the side wall of the connecting rod 73 will also rotate, causing the tubular iron tower component to rotate slowly one circle, avoiding the need to manually move the welding machine position multiple times, which would cause the welding line to deviate, thereby greatly improving the efficiency and quality of the welding of the entire tubular iron tower component. After the welding of the tubular iron tower component is completed, the user can start the clamping motor 81 to run in reverse. At this time, under the elastic force of the return spring 92, the clamping plate 89 will drive the sliding column 88 to move the piston plate 91 toward the outside of the inner cavity of the sliding sleeve 87. At this time, the volume of the upper cavity of the sliding sleeve 87 continues to decrease, and the internal air pressure continues to increase. Finally, the air in the sliding sleeve 87 can enter the inner cavity of the clamping plate 89 through the air outlet 882 and the air outlet channel 881, and finally high-pressure gas is ejected from the air nozzle 93 to accelerate the flow of air inside the tubular iron tower component, thereby realizing the function of cooling the tubular iron tower component that has just been welded, and further improving the efficiency of the entire device in welding tubular iron tower components.

[0031] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
