[0002] Bridges are used to cross roads, rivers, valleys or other obstacles to facilitate the passage of people, vehicles and trucks. They are mainly composed of rectangular piers, footboards, main beams, abutments and anti-collision guardrails. In bridge construction, rectangular piers are a vital component of the bridge structure, and they undertake multiple functions such as support, load distribution, connection and stability to ensure the normal operation and safety of the bridge. During the construction of rectangular piers, safety ladders are usually used to construct the rectangular piers.

[0003] At present, the traditional safety ladder device adopts a protective net installed on the outside to prevent construction workers from accidentally falling, and the outside of the protective net is reinforced with diagonal rods to prevent the protective net from falling off. However, the diagonal rods are directly fixed to the frame with screws. Under long-term use, affected by external factors, the screws expand and contract due to heat and cold, causing the screws to loosen, causing the diagonal rod and the protective net to fall, posing a certain personal threat to the personnel above and below. At the same time, during the construction process, a single method of hoisting materials is adopted, and the materials sway in the air, and there is a risk of falling.

[0004] Therefore, a safety ladder for rectangular bridge piers with a protective function is provided. Utility Model Content

It solves the problem that the protective net of the traditional ladder and its reinforced diagonal rods are fixed with screws and there is a risk of falling off, and the shaking caused by the use of a single lifting material is prone to falling, posing a threat to the lives of construction personnel.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a safety ladder device for a rectangular pier of a bridge with a protective function, comprising a frame assembly and a conveying assembly, wherein the frame assembly comprises a supporting plate, a first mounting interface is arranged on the supporting plate, an outer support rod is fixed on the first mounting interface, an outer protective net is fixed between the outer support rods, and a mounting groove is opened in the supporting plate, and a ladder is fixed in the mounting groove. In addition, a conveying groove is opened in the middle of the supporting plate, a second mounting interface is fixed on the conveying groove, and an inner support rod is fixed on the second mounting interface. The first mounting interface is arranged at four angular positions on the supporting plate, an outer support rod is plugged into the first mounting interface, and a second mounting interface is arranged at four angular positions at the edge of the conveying groove, and an inner support rod is plugged into the second mounting interface.

[0018] As a further improvement of the above solution, a slide rail is fixed on the track connecting rod, and a slide groove is opened on the side of the platform plate, and the slide rail is movably sleeved in the slide groove;

[0019] Through the above technical solution, the track connecting rod is used to connect with the slide rail. When the platform plate is lifted up and down, it slides up and down on the side of the slide rail through the slide groove, thereby increasing the lifting stability of the platform plate.

[0020] As a further improvement of the above solution, a stabilizing wheel is movably hinged in the slide groove, and the stabilizing wheel is attached to the side of the slide rail;

[0021] Through the above technical solution, when the platform plate is raised and lowered, the stabilizing wheel rotates on the side of the slide rail and the track connecting rod, thereby reducing the friction resistance between the slide groove and the slide rail and the track connecting rod.

[0022] As a further improvement of the above solution, a fixing hole is provided on the platform plate, and the hook is fixed in the fixing hole;

[0023] Through the above technical solution, the hook is specifically a D-shaped or O-shaped locking ring, which is fixed in the fixing hole. When the rope is reeled in, it can drive the platform plate to rise and fall. In addition, the hook can be detached from the fixing hole to independently hang the bagged material for lifting and transportation.
