Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a safety engineering ladder. Background Art

[0002] As the name implies, an engineering ladder is a ladder used for engineering construction. It is portable by itself. Construction workers often carry the engineering ladder to work at heights during construction and are widely used in engineering and daily life.

[0003] For example, the Chinese utility model patent (CN221503181U) discloses a multi-functional safety engineering ladder, which records: "Comprising a second body and a first body, the second body is arranged on the right side of the first body, and the upper part of the second body and the upper part of the first body are rotatably connected by a hinge. A plurality of steps are fixedly connected inside the second body and the first body. A support assembly is fixedly connected to the front surface of the first body. The support assembly is adapted to a storage box. An elongated groove is integrally formed above the right side of the second body. A chute is formed on the lower surface inside the elongated groove. A slider is slidably connected to the inner side wall of the chute".

[0004] When construction workers carry tools and materials and use the above engineering ladder to climb to work at heights, when they lack some tools or materials, they need to climb down the ladder to get them by themselves, which is time-consuming and laborious and affects the construction progress. Or they need another construction worker located below the ladder to hold up and hand over the tools or materials. However, the tools are easy to fall and the materials are easy to spill during the transfer process. Therefore, this application proposes a safety engineering ladder. Summary of the Utility Model

[0005] Based on this, in view of the above technical problems, it is necessary to provide a safety engineering ladder. Through the overall structural cooperation design, when a construction worker working above lacks some tools or materials, another construction worker located below places the tool or material inside the storage box and then operates the controller to conveniently start the reduction motor to drive the threaded column to rotate, so that the lifting seat and the storage box are driven to move up under the guidance of the guide post to achieve transfer. The transfer process is stable and not prone to falling or spilling, effectively avoiding affecting the construction progress.
