Description

Cage type cat ladder Technical Field The utility model belongs to the field of building construction, and particularly relates to a cage type cat ladder. Background The cage type cat ladder belongs to the fields of building construction, high-altitude operation and safety protection equipment, is widely applied to scenes such as buildings, bridges, tunnels, industrial plants and municipal works, and is used for providing safe and stable up-and-down passages for high-altitude operation personnel and has the anti-falling protection function. In the prior art, if workers fall down accidentally due to emergency such as physical weakness, sudden diseases and foot loss in the climbing process of the workers, the workers lack effective protective measures, and possibly fall to the ground directly, so that serious injury and even life threatening are caused. Therefore, the existing cat ladder is structurally lack of a simple and convenient safety protection structure for workers, and is not provided with a timely protection scheme for accidental work during use. Disclosure of utility model In order to overcome the defect that the existing cat ladder is lack of a simple and convenient safety protection structure for workers in structure, a cage type cat ladder is provided. The technical scheme includes that the cage type ladder comprises a ladder body, a barrier strip and first fixing columns, wherein two surrounding guardrails are arranged at the right end of the ladder body, connecting bars are fixedly connected to the right ends of the two surrounding guardrails, first connecting plates are fixedly connected to the right ends of the connecting bars, a plurality of first groove bodies are arranged on the first connecting plates, the barrier strip is hinged to the first groove bodies, the upper ends of the barrier strip are concave, U-shaped connecting plates are fixedly connected to the right ends of the barrier strip, pressing blocks are arranged at the front end and the rear end of the U-shaped connecting plates, first fixing columns are arranged on the first connecting plates in a sliding mode, stop blocks are fixedly connected to the outer walls of the first fixing columns, third fixing columns are arranged on the barrier strip, and hinge frames are fixedly connected to the lower ends of the inner walls of the first groove bodies. Preferably, the upper and lower parts of the left end of the first connecting plate are fixedly connected with two connecting discs respectively, and one end, close to each other, of the upper and lower flush connecting discs is fixedly connected with a second fixing column. Preferably, the outer wall of the second fixing column is slidably provided with a limiting ring, and one end, close to each other, of the two limiting rings is fixedly connected with the third fixing column. Preferably, the right end of the first connecting plate is fixedly connected with two lug plates, and the lug plates slide on the first fixing columns. Preferably, a plurality of second groove bodies are formed at the upper end of the pressing block. Preferably, the outer wall of the third fixing column is fixedly connected with a connecting ring, and the third fixing column, the connecting ring, the connecting disc and the second fixing column are made of stainless steel. Preferably, the lower end of the barrier strip is fixedly connected with a limiting support leg, and the right end of the limiting support leg and the left end of the first connecting plate are mutually attached. The cage ladder has the beneficial effects that by arranging the structures such as the barrier strips and the third fixing columns, when a worker climbs upwards, the third fixing columns move upwards along with the worker and trigger the barrier strips to turn over, the barrier strips are kept fixed by leaning on the first connecting plate through the supporting structure, when the worker falls downwards in an emergency, the third fixing columns can fall downwards rapidly, the barrier strips on the corresponding floors can intercept the worker, so that the worker is hung rapidly, falling injury of the worker is effectively prevented, and life safety of the worker is guaranteed.
