[0028] A ladder assembly 3 is installed between the two cross bars of the frame 401, and the ladder assembly 3 includes two groups of vertical bars 1 301 and vertical bars 2 302, which are slidably connected up and down, and a plurality of cross bars 303 are fixedly installed between the two groups of vertical bars 1 301 and vertical bars 2 302, which are set to four in this embodiment, and a half ring 1 304 is fixedly installed on the upper end of the vertical bar 1 301 and the lower end of the vertical bar 2 302. The ladder assembly 3 is placed between the two cross bars of the frame 401 by retracting the vertical bar 1 301 and the vertical bar 2 302, and then stretched so that the half ring 1 304 is pressed against the cross bar, and the half ring 2 305 is fixedly installed on the half ring 1 304 for fixing, and the half ring 1 304 and the half ring 2 305 are fixed by bolts, and the half ring 1 304 and the half ring 2 305 completely cover the cross bar.

[0029] In this embodiment, the pedal assembly 2 includes a pedal 201, and four slide seats are arranged on both sides of the lower end of the pedal 201, on which two telescopic shafts 203 and two sleeve shafts 204 are slidably mounted respectively. The telescopic shaft 203 and the sleeve shaft 204 are slidably connected, and a snap ring 202 is fixedly mounted on the end of the telescopic shaft 203, and the snap ring 202 extends to the outside of the pedal 201. A snap ring 205 is fixedly mounted on the end of the sleeve shaft 204, and the snap ring 205 extends to the outside of the pedal 201. The snap ring 1 202 and the snap ring 205 are respectively clamped on the cross bars of the two frames 401. When the distance between the two frames 401 is adjusted, the pedal assembly 2 is also adjusted accordingly. When the pedal assembly 2 is disassembled and assembled, it can also be retracted to provide convenience for disassembly and assembly.

[0030] In this embodiment, the sliding assembly 1 includes a sleeve 101, an inclined surface is provided on the upper end of the sleeve 101, an opening is provided at the lowest point of the inclined surface, and the opening distance is the same as the inner diameter of the sleeve 101, and protruding plates 104 are fixedly installed on both sides of the opening, a central axis 106 is rotatably installed on the protruding plate 104, a blocking plate 103 is fixedly installed on the central axis 106, and the blocking plate 103 is hinged on the protruding plate 104 through the central axis 106, a torsion spring 105 is fixedly installed between the central axis 106 and the protruding plate 104, and the blocking plate 103 is tightly attached to the lower part of the protruding plate 104 in a natural state, a lifting ring 102 is fixedly installed on the sleeve 101, the sleeve 101 is slidably installed on the vertical rod of the frame 401, and the safety belt is fixed on the lifting ring 102.

[0031] Working principle: according to the required height, multiple support frames 4 are provided. In this embodiment, two support frames are provided. The fixing pin 405 is removed, and the distance between the two frames 401 is adjusted. Then, the fixing pin 405 is inserted to fix the two frames 401. During the adjustment process, the connecting rod between the two frames 401 slides and rotates to adjust. The ladder assembly 3 is retracted to reduce the distance between the vertical rod 1 301 and the vertical rod 2 302. The half ring 1 304 on the vertical rod 2 302 is pressed against the cross bar on the lower side of the frame 401. The vertical rod 1 301 is slid upward so that the half ring 1 304 on the vertical rod 1 301 presses against the cross bar on the upper side of the frame 401. Then, the half ring 1 304 on the vertical rod 1 301 is pressed against the cross bar on the upper side of the frame 401. The ring 2 305 is fixed with bolts, the distance between the telescopic shaft 203 and the sleeve shaft 204 is adjusted, and the clamping ring 1 202 and the clamping ring 205 are placed on the frame 401 for stepping on. The safety belt is fixed on the hanging ring 102, and the construction workers begin to climb. During the process, the sleeve 101 slides upward. When encountering the obstruction of the cross bar, the sleeve 101 will rotate due to the inclined surface and rotate to the notch. Then the cross bar pushes the blocking plate 103 to rotate downward, and then completely passes through the cross bar. The blocking plate 103 returns to its original position due to the action of the torsion spring 105. If the construction workers accidentally fall, the sleeve 101 will not slide downward and will be stuck by the cross bar.
