[0002] An iron tower is a tall tower-shaped building made of steel materials. It is usually used to support and install facilities such as wireless communications, radio and television, and power transmission lines. Because it is always exposed to the outside, it will be affected by factors such as wind, sun, rain, etc. in the natural environment, and thus needs frequent maintenance and inspection. During maintenance and inspection, workers are required to climb up, and thus they need to use equipment for climbing iron towers.

[0003] A climbing device for tower maintenance disclosed in a Chinese patent with publication number CN219440603U is characterized in that it includes an upper clamping ring assembly, a lower clamping ring assembly, an upper drive assembly, a lower drive assembly and an intermediate drive assembly, wherein the upper clamping ring assembly includes a first clamping ring and a second clamping ring, and a first connecting rod is hinged between the two, and the lower clamping ring assembly includes a third clamping ring and a fourth clamping ring, and a second connecting rod is hinged between the two, one end of the upper drive assembly is connected to the first clamping ring, and the other end is connected to the second clamping ring, one end of the lower drive assembly is connected to the third clamping ring, and the other end is connected to the fourth clamping ring, and one end of the intermediate drive assembly is connected to the upper clamping ring assembly, and the other end is connected to the lower clamping ring assembly. The utility model realizes the climbing function of the utility model through the upper drive assembly, the lower drive assembly and the intermediate drive assembly, and solves the problem of artificial climbing danger.

[0004] In the process of implementing this application, the inventor discovered that there are at least the following problems in this technology: although the above technical solution can realize the climbing function and solve the problem of the danger of manual climbing, in actual use, the shapes of the tower base columns are different, and many of them are square columns, while this technical solution is mostly suitable for cylindrical climbing. Therefore, further improvements can be made. Utility Model Content

[0005] To solve the above-mentioned problems, the utility model provides the following technical solutions: a climbing device for tower maintenance, comprising a climbing frame, a slide rail is fixedly installed on the inner middle part of the climbing frame, a fixed block is fixedly installed on the top of the slide rail, a slider is slidably connected inside the slide rail, an electric push rod is fixedly installed between the fixed block and the slider, baffles are fixedly installed on the inner walls on both sides of the climbing frame, and clamping and positioning components are provided on the front side of the fixed block and the slider.

[0007] As an optimization, an arc groove is opened in the middle of the clamping frame, and the clamping rod has an arc edge portion corresponding to the arc groove. The arc groove and the arc edge portion in the middle are used to facilitate clamping and climbing of the cylindrical base column, thereby improving practicality.

[0008] As an optimization, a turning handle is fixedly installed at the end of the screw rod, and the turning handle is used to facilitate manual rotation of the screw rod, which in turn drives the clamping rod to approach the clamping frame and clamp it to the outside of the base column.

[0009] As an optimization, an empty slot is provided inside the clamping frame, and a driving component for driving the screw rod to rotate automatically is arranged at the empty slot of the clamping frame.

[0010] As an optimization, the driving assembly includes a servo motor fixedly mounted on the outside of the clamping frame, a main gear fixedly mounted on one end of the output shaft of the servo motor, a slave gear rotatably connected inside the empty groove, and the slave gear and the rotating shaft are fixedly mounted, the slave gear and the main gear are meshingly connected, and by driving the screw to rotate inside the threaded groove, the clamping rod is driven close to the clamping frame and clamped and fixed on the outside of the base column.

[0011] As an optimization, the surfaces of the clamping frame and the clamping rod on one side opposite to each other are provided with convex pads, which can increase the frictional force in contact with the surface of the base column and improve the stability of clamping during climbing.

[0012] The beneficial effects of the utility model are:

[0013] 1. The climbing device for tower maintenance drives the main gear to rotate through the servo motor, and then drives the rotating shaft to rotate synchronously through the empty groove, so that the screw rod is driven to rotate inside the thread groove, and then the clamping rod can be driven to approach or move away from the clamping frame by controlling the rotation direction of the main gear, so it can switch between clamping and loosening, and then through the cooperation of the arc groove and the arc edge, the cylindrical base column can be clamped and fixed, so it can be suitable for base columns of different shapes and sizes, thereby improving practicality.

[0014] 2. The climbing device for tower maintenance has the upper clamping rod away from the clamping frame, so it is no longer clamped and fixed from the top. The electric push rod can be started to drive the fixing block to move upward, so that the climbing frame as a whole slides upward relative to the slider, and then the clamping rod is brought close to the clamping frame and clamped and fixed on the outside of the base column, while the lower clamping rod is away from the clamping frame. At this time, starting the electric push rod will pull the slider to move upward, and then the clamping rod is brought close to the clamping frame and clamped and fixed on the outside of the base column. The above steps are repeated back and forth to realize the automatic climbing function. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figure 3-4 The clamping frame 8 has an empty slot 13 formed inside, and the clamping frame 8 is provided with a driving assembly 14 for driving the screw rod 11 to rotate automatically at the empty slot 13.

[0026] When in use, first hold the clamping rod 9 with one hand and turn the screw rod 11 with the other hand to rotate in the thread groove 12, which will drive the clamping rod 9 away from the clamping frame 8, so that the opening between the clamping frame 8 and the clamping rod 9 will be enlarged, and then it can be clamped on the outside of the base column, and then the screw rod 11 is rotated in the opposite direction, so that the clamping rod 9 will be driven close to the clamping frame 8, and then the clamping frame 8 and the clamping rod 9 will be clamped and fixed on the outside of the base column;
