Technical Field

[0001] The utility model relates to the technical field of communication engineering climbing tools, in particular to a portable climbing ladder for communication engineering. Background Art

[0002] During the construction of communication projects, the installation of optical fiber cables is often involved. When high-altitude installation is required, a ladder is needed to facilitate workers to climb to the height of cable installation. In order to facilitate the transportation of the ladder, aluminum alloy is usually used, which can reduce the overall weight of the ladder and improve its portability.

[0003] Existing portable ladders usually have rubber anti-slip structures installed on the top, bottom and top of the steps of the ladder. When the top of the ladder is against the wall and the bottom touches the ground, the rubber anti-slip structure can increase the friction between the ladder and the wall and the ground to prevent the ladder from slipping. In addition, the rubber anti-slip structure installed on the steps can increase the friction between the worker's feet and the step bracket to prevent the feet from slipping, effectively improving the safety factor when using the ladder.

[0004] However, in actual use, when the staff needs to pull the optical fiber cable to the high-altitude installation location, they either hold one end of the cable and then climb to the installation location with the help of a ladder, or another staff member uses a pole or other tool to lift one end of the cable to the installation location, and then the staff standing on the top of the ladder catches the cable. This operation is inconvenient and significantly reduces the convenience of optical fiber cable installation. Therefore, the present application proposes a portable climbing ladder for communication engineering that can facilitate the installation of optical cables. Utility Model Content

[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments. Example

[0030] like Figure 1-Figure 5 When the ladder is used as a climbing step, the ladder handle 2 is tightened to the bottom of the ladder and the ladder handle 3 is tightened to the bottom of the ladder, so that the ladder can be easily climbed.

[0031] A cable traction assembly 7 is movably installed on the outer wall of the above-mentioned support plate 1. The cable traction assembly 7 consists of a traction seat 71, a traction rope 72 and a pull ring 73. The above-mentioned traction seat 71 is slidably installed on the outer wall of the support plate 1, and the pull ring 73 is movably installed on one side of the support plate 1. A traction rope 72 is fixedly installed between the above-mentioned pull ring 73 and the traction seat 71, and one end of the optical fiber cable is fixed to the traction seat 71. When the staff climbs to the top of the ladder, they hold the pull ring 73 and drive the traction rope 72 to move upward, and then drive the traction seat 71 to slide upward along the support plate 1, so as to facilitate lifting the end of the optical fiber cable to a high altitude position, thereby improving the convenience of cable lifting when installing the optical fiber cable.

[0032] Furthermore, connecting plates 63 are fixedly installed at both ends of the ladder foot positioning plate 6 away from each other. The end of the connecting plate 63 away from the ladder foot positioning plate 6 is rotatably installed on the outer wall of the support plate 1 through a rotating shaft, ensuring that the ladder foot positioning plate 6 can be rotated and adjusted, and can be flatly covered on the soil surface after adjustment. A number of through-holes 61 are drilled on the ladder foot positioning plate 6. When the ladder foot positioning plate 6 needs to be fixed on the soil layer, the sharp end of the dowel 62 is passed through the through-hole 61 and pressed into the soil layer to fix the ladder foot positioning plate 6. When the ladder is used on the ground of an outdoor soil structure, the bottom of the ladder can be prevented from moving, thereby enhancing the safety factor of the ladder when used outdoors.

[0033] Secondly, two assembly openings 22 are carved on the pedal 2. When the pedal 2 is installed, bolts can be used from the assembly openings 22 to fix the pedal 2 to the inner wall of the support plate 1, which makes it convenient to disassemble and assemble the pedal 2. When carrying the ladder, the pedal 2 can be removed to reduce the space occupied by the ladder and provide convenience for carrying it; the top of the above-mentioned pedal 2 is fixedly installed with a rubber pad 21. When the staff climbs with the help of the ladder, the rubber pad 21 can increase the friction between their feet and the pedal 2, prevent their feet from slipping, and improve the safety factor when climbing.

[0034] Furthermore, the traction seat 71 includes a built-in circular plate 712, which is movably mounted in the limiting groove 4 excavated on the outer wall of the support plate 1. A connecting shaft 713 is fixedly mounted on the above-mentioned built-in circular plate 712, and one end of the connecting shaft 713 extends to the outside of the limiting groove 4. Two limiting plates 5 are fixedly mounted on the outer wall of the support plate 1. The above-mentioned two limiting plates 5 are symmetrically arranged and cover the notch of the limiting groove 4. The connecting shaft 713 is set in the gap between the two limiting plates 5. The plate 712 is installed on the inner side of the limiting plate 5, which can prevent the built-in circular plate 712 from falling off the limiting groove 4; the above-mentioned connecting shaft 713 is fixedly installed with an external circular plate 711 on the end away from the built-in circular plate 712, and the external circular plate 711 is arranged on the outside of the limiting plate 5. The main structure of the traction seat 71 is composed of the external circular plate 711, the built-in circular plate 712 and the connecting shaft 713. With the cooperation of the limiting groove 4 and the limiting plate 5, the traction seat 71 can be ensured to slide stably along the limiting groove 4.

[0035] The top of the traction rope 72 passes through the circular hole and is fixedly connected to the pull ring 73. At this time, the pull ring 73 is movably mounted above the frame plate 11, which can limit the top of the traction rope 72 to prevent the top of the traction rope 72 from falling to the ground.

[0036] In this embodiment, first, when the ladder is used, if it is used on a flat floor indoors (cement floor, floor tiles, etc.), the top of the ladder is leaned against the wall. The rubber sheet 3 on the top of the support plate 1 can increase the friction between the ladder and the wall, and the rubber sheet 3 installed at the bottom of the support plate 1 can increase the friction between the ladder and the ground, which can prevent the ladder from slipping; if it is used on the soil ground outdoors, first rotate the ladder foot positioning plate 6 and adjust the angle so that the ladder foot positioning plate 6 is flatly covered on the soil ground, and then insert the dowel 62 through the through-hole 61 drilled on the ladder foot positioning plate 6, and press the sharp end of the dowel 62 into the soil by stepping on it, so that the ladder foot positioning plate 6 can be fixed, so that the ladder foot part can be stably erected on the ground, preventing the ladder foot from moving, and effectively enhancing its safety factor for outdoor use.

[0037] When it is necessary to lift the optical fiber cable to the high-altitude installation position, the worker first fixes the end of the cable on the cable fixing block 715 before climbing the ladder to ensure that the cable end can be firmly tied and fixed to one side of the traction seat 71. When the worker climbs to the top of the ladder, he holds the pull ring 73 and starts to pull the traction rope 72 upward, which can then drive the traction seat 71 to slide upward along the limit groove 4 excavated on the support plate 1. When the traction seat 71 is lifted to the high-altitude installation position, the worker removes the end of the cable from the cable fixing block 715 to facilitate subsequent installation operations; in this process, there is no need for another worker to use a pole to push the cable end to the high-altitude installation position, nor is there a need for the worker climbing the ladder to hold the cable to climb. While ensuring safety, the difficulty of the cable lifting operation can be reduced, effectively improving the convenience of optical fiber cable installation.

[0038] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
