[0037] See also Figure 4 and Figure 7 The limiting member 6 includes two mounting plates 61 for connecting various components. The two mounting plates 61 are respectively fixedly connected to the left and right sides of the connection box 3. A connecting plate 62 is provided on the upper part of the mounting plate 61 for connecting various components. An auxiliary rod 63 is passed through and rotatably connected to the front part of the connecting plate 62 for coordinating the connection between the connecting plate 62 and the mounting plate 61. The auxiliary rod 63 is fixedly connected to the mounting plate 61. A compression spring 64 is fixedly connected between the connecting plate 62 and the connection box 3 for coordinating the rotation and reset of the connecting plate 62. One end of the compression spring 64 is connected to the connection box 3, and the other end is connected to the connecting plate 62. The rear side of the connecting plate 62 is fixedly connected to a limiting plate 65 for limiting the fixed component 5.

[0038] Working principle: When the staff needs to climb up along the steel climbing frame, the staff needs to fix the hook of the safety rope with the No. 1 hanging ring 4, and then start climbing up. When the staff climbs up, the protection component will be driven to move upward, and the connecting box 3 will drive the slider 32 to slide in the slide groove 11. At the same time, when the connecting box 3 moves upward, it will drive the fixing component 5 and the limiter 6 to move upward together. When the fixing rod 51 hits the lower part of the support rod 2, due to the upward movement of the connecting box 3, the support rod 2 will apply a downward force to the fixing rod 51, and the fixing rod 51 will apply pressure to the support member 52, and the main rod 521 and the auxiliary rod 522 will torsionally The spring 524 produces compression, so that the main rod 521 and the auxiliary rod 522 are folded toward the receiving groove 31, thereby driving the fixing rod 51 to retract toward the receiving groove 31, and the upward movement of the connecting box 3 can be realized. When the connecting box 3 continues to move upward, the fixing rod 51 will pass over the support rod 2 on its upper part. Due to the loss of the pressure applied by the support rod 2, the torsion spring 524 will drive the main rod 521 and the auxiliary rod 522 to reset, so that the support member 52 supports the fixing rod 51 again. When the staff member accidentally moves downward in an unexpected situation, the fixing rod 51 will be stuck on the upper part of the support rod 2 because the support member 52 supports the fixing rod 51, thereby fixing the staff member.

[0039] When the staff has finished the inspection and maintenance and needs to return to the ground along the steel climbing frame, the staff can first fix the safety rope to the support rod 2, and then pull the connecting rope 69 forward by hand, and the connecting rope 69 will then pull the front ends of the two connecting plates 62 closer to each other through the fixed block 66 connected thereto, and the connecting plates 62 will rotate around the auxiliary rod 63, and at the same time squeeze the compression spring 64, and the two connecting plates 62 will open in an eight-shaped shape, thereby driving the limit plate 65 to open, and the limit block 651 will be moved away from the front of the storage groove 31, and then the two fixing rods 51 will be pressed back into the storage groove 31, and then the No. 2 hanging ring 67 will be released again, and the compression spring 64 will then drive the two connecting plates 62 to reset, and the connecting plate 62 will then drive the limit plate 65 The limit block 651 is reset, and the limit plate 65 will block the front side of the storage slot 31, thereby limiting the fixing assembly 5 in the storage slot 31, making it convenient for the staff to move downward. Then the staff needs to fix the hook of the safety rope with the No. 2 hanging ring 67. If the staff accidentally falls or falls during the downward movement, the force of the staff leaning backward or falling downward will pull the No. 2 hanging ring 67, and the No. 2 hanging ring 67 will pull the two connecting ropes 69, and the two connecting ropes 69 will drive the two limit plates 65 to open to both sides. Under the action of the torsion spring 524, the support member 52 will support the fixing rod 51 again, causing it to pop out of the storage slot 31, so that the fixing rod 51 can be stuck with the support rod 2, thereby fixing the staff.
