[0028] On the basis of the above structure, a locking bolt 5 is threadedly mounted on the side wall of the bracket 4 , and both ends of the transverse axis 6 are respectively connected to the bearings of the two brackets 4 .

[0029] In this embodiment, the locking bolt 5 is used to facilitate the positioning of the transverse axis 6 and the connecting plate 7, so that after the climbing ladder is used, the connecting plate 7 can be rotated and folded for storage, thereby facilitating the carrying and transfer of the climbing ladder.

[0030] Based on the above structure, the clamping assembly 8 includes a mounting ring 81, a connecting rod 82, a long screw 83 and a nut 84. The connecting rod 82 is welded and fixed to the outer wall of the mounting ring 81 on one side close to the connecting plate 7. One end of the connecting rod 82 close to the connecting plate 7 is fixedly connected to the connecting plate 7. A long screw 83 runs through the other end of the mounting ring 81, and a nut 84 is threadedly sleeved on the outer side of the long screw 83.

[0031] In this embodiment, the clamping assembly 8 is provided to facilitate connection with the monitoring rod, and can provide support and positioning effects for the ladder body 1, thereby facilitating stable installation of the climbing ladder.

[0032] On the basis of the above structure, the guide groove 10 includes an inclined straight line segment and a horizontal straight line segment located at the bottom of the inclined straight line segment, and the horizontal straight line segment is connected to the inclined straight line segment.

[0033] In this embodiment, the guide groove 10 is provided to facilitate the adjustment of the support and positioning assembly 9 .

[0034] On the basis of the above structure, the supporting and positioning assembly 9 includes a screw rod 91, a movable block 92, a resistance rod 93 and a fixed column 94. The screw rod 91 is connected to the bearing of the connecting plate 7. The movable block 92 is threadedly sleeved on the outer side of the screw rod 91. The resistance rods 93 are rotatably connected to the outer walls on both sides of the movable block 92. Fixed columns 94 are welded and fixed to the outer walls on the sides where the two resistance rods 93 face away from each other.

[0035] On the basis of the above structure, one end of the fixing column 94 away from the abutting rod 93 extends to the inner side of the guide groove 10 .

[0036] In this embodiment, by rotating the screw rod 91, the movable block 92 can be controlled to drive the interference rod 93 to move, and under the guidance of the guide groove 10, the fixed column 94 can drive the interference rod 93 to automatically rotate while moving. By controlling the end of the interference rod 93 to interfere with the fixed plate 3, the interference limit of the fixed plate 3 and the ladder body 1 is achieved, which can further improve the stability of the climbing ladder in use.

[0037] The working principle of the utility model is as follows:

[0038] When in use, firstly, the mounting ring 81 is mounted on the outside of the target monitoring pole, and then the mounting ring 81 is fixed by the long screw 83 and the nut 84, and then the locking bolt 5 is loosened to release the positioning of the horizontal axis 6, and the ladder body 1 is slowly moved toward the monitoring pole to prevent it from falling, so that the top of the ladder body 1 contacts the monitoring pole. Figure 1As shown in , at this time, the ladder body 1 is inclined and preliminarily positioned, and then the screw rod 91 is manually rotated to control the movable block 92 to drive the interference rod 93 to move synchronously. At this time, under the guidance of the inclined straight section of the guide groove 10, the fixed column 94 can drive the interference rod 93 to move and rotate downward to be inclined, and when the fixed column 94 enters the horizontal straight section of the guide groove 10, the movable block 92 and the inclined interference rod 93 can be relatively stationary and move stably until the end of the interference rod 93 contacts the fixed plate 3 as shown in FIG. Figure 2 As shown in , the interference limit of the ladder body 1 can be achieved, which can improve the stability of the use state of the climbing ladder, ensure the stability of the ladder body 1 during use, improve safety, and make the operation quick and convenient;

[0039] When this climbing ladder is in use, Figure 1 and Figure 2 As shown in the figure, a triangular structure can be formed between the fixing plate 3, the abutting rod 93 and the connecting plate 7, and between the ground, the monitoring rod and the ladder body 1. By utilizing the stable characteristics of the triangular structure, the overall stability of the climbing ladder can be effectively enhanced during actual use;

[0040] When the climbing ladder is moved after use, the running wheels 2 installed at the bottom of the ladder body 1 can be rotated to facilitate the movement of the climbing ladder, which is more labor-saving.

[0041] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
