[0002] Industrial construction projects often install outdoor steel ladders to facilitate evacuation and maintenance. In my country, especially in northern China, winter snowfall can be heavy, often covering the ladders with a significant amount of snow. Therefore, to ensure safety and prevent slips, personnel must be assigned to clear the snow. Heavy, prolonged snowfall can be too late for staff to clear, and prolonged accumulation of snow can easily cause ice to form, posing a significant safety hazard. Utility Model Content

[0003] The purpose of the utility model is to provide a device for removing snow from outdoor steel ladders, so as to solve the problem that snow on outdoor steel ladders cannot be handled in time, reduce the safety hazards caused by snow accumulation on outdoor steel ladders, and reduce the cost required for manual snow removal.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A device for clearing snow from outdoor steel ladders comprises a plurality of air ducts and air ducts arranged on the steel ladder, a plurality of air blowing ports being provided on one side of the air duct, an air inlet connected to the air duct being provided on the other side of the air duct, a rotating shaft rotatably connected to the steel ladder being provided at both ends of the air duct, a slide being slidably connected to both sides of the steel ladder, a plurality of first connecting blocks being rotatably connected to the slide, a second connecting block being rotatably connected to the first connecting block at the end of the rotating shaft, and a drive motor for driving the slide to reset and move on the steel ladder.

[0006] Furthermore, a heating block is provided at the air inlet of the air duct.

[0007] Furthermore, the end of the air inlet is provided with a connecting flange, and also includes a flange plate used in conjunction with the connecting flange.

[0008] Furthermore, the movable end of the driving motor is provided with a first rocking rod, and further includes a third connecting block rotatably connected to the first rocking rod and the end of the slide.

[0009] Furthermore, the movable end of the driving motor is provided with an eccentric wheel, and the eccentric wheel is symmetrically provided with a first arc groove and a second arc groove, the first arc groove and the second arc groove are connected, and the end of the skateboard is provided with a first column that contacts the first arc groove and the second arc groove in sequence.

[0010] Furthermore, a second rocker arm is provided at the movable end of the driving motor, a sliding groove is provided at the end of the sliding plate, and a second column is provided at the end of the second rocker arm for sliding contact with the sliding groove.

[0011] Furthermore, a plurality of bearing seats rotatably connected to the rotating shaft are respectively provided on both sides of the steel ladder.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. When snow begins to accumulate on the outdoor steel ladder, the fan connected to the air duct is turned on. The airflow generated by the fan enters the air duct from the air inlet and is blown toward the steel plate of the ladder through several air outlets, causing the snow on the steel plate to fall off. This automatically clears the snow on the ladder, avoiding the need for manual cleaning due to long-term snow accumulation, and reducing the cost of manual snow removal.

[0014] 2. The driving motor drives the slide to reset and move on the steel plate, driving one end of several first connecting blocks to move together. Since the second connecting block provided at the end of the rotating shaft is rotatably connected to the first connecting block, when the slide moves obliquely upward on the steel plate, the component force generated drives the second connecting block to swing counterclockwise through the first connecting block; when the slide moves obliquely downward on the steel plate, the component force generated drives the second connecting block to swing clockwise through the first connecting block, thereby driving the rotating shaft to swing back and forth on the steel plate, driving the air duct to swing back and forth on the steel plate, and then blowing away the snow on the steel ladder at more angles, thereby improving the effect of the snow removal device in removing accumulated snow.
