[0004] In order to achieve the above object, the technical scheme adopted by the utility model is as follows:
[0005] A safety protection railing for a platform ladder opening, including a ladder and a platform. Left and right sliding rods are fixedly connected to both sides of the platform entrance. The left and right sliding rods are slidably connected to a protection railing through upper and lower sliding rings. The ladder is connected to the entrance of the platform. The upper and lower sliding rings are fixedly connected to the protection railing. Lower limits are provided at the lower ends of the left and right sliding rods. Ladder handrails are fixedly connected to both sides of the ladder, and one ends of the two ladder handrails are respectively fixedly connected to the tops of the left and right sliding rods.
[0006] Both the left and right sliding rods are U-shaped pipe fittings made by bending steel pipes.
[0007] The protection railing is a square or cross-shaped fitting made by butt welding steel pipes.
[0008] The upper and lower sliding rings are elliptical fittings made by bending steel pipes.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] The utility model adopts a slidable protection railing as the safety protection for the entrance of the platform on the ladder, so that there is no gap in the platform entered through the ladder at a high place, and there are protection railings all around, thereby reducing the risk of working at heights; manual operation is flexible and convenient, time-saving and labor-saving, and does not affect normal work at all; the structure is simple and easy to manufacture, the manufacturing cost is low, and the maintenance and replacement are convenient; the principle is simple, the safety protection function is remarkable, and it can be widely promoted and used.

Therefore, it should not be construed as a limitation of the present utility model.
[0016] Embodiment 1
[0017] As Figure 1-2 shown, a safety guardrail for a platform ladder opening according to the present utility model includes a ladder 2 and a platform 3. On both sides of the entrance of the platform 3, a left sliding rod 5 and a right sliding rod 6 are fixedly connected. The left sliding rod 5 and the right sliding rod 6 are slidably connected to a guardrail 7 through an upper sliding ring 8 and a lower sliding ring 9. The ladder 2 is connected to the entrance of the platform 3. The upper sliding ring 8 and the lower sliding ring 9 are fixedly connected to the guardrail 7. A lower limit 10 is provided at the lower ends of the left sliding rod 5 and the right sliding rod 6. Ladder handrails 1 are fixedly connected to both sides of the ladder 2, and one ends of the two ladder handrails 1 are respectively fixedly connected to the tops of the left sliding rod 5 and the right sliding rod 6; the left sliding rod 5 and the right sliding rod 6 are both U-shaped pipe fittings made by bending steel pipes; the guardrail 7 is a square or cross-shaped fitting made by butt-welding steel pipes; the upper sliding ring 8 and the lower sliding ring 9 are elliptical fittings made by bending steel pipes.
[0018] Steel pipes are welded on both sides of the entrance of the ladder 2 and the platform 3 to make the left sliding rod 5 and the right sliding rod 6. Both the left sliding rod 5 and the right sliding rod 6 are bent U-shaped pipe fittings, and their height generally exceeds 1.5 times that of the platform guardrail 4. The guardrail 7 is square or cross-shaped welded by pipes, and its weight is controlled within 10 kg, so that the operator can easily lift it with one hand. The upper sliding ring 8 and the lower sliding ring 9 are oval fittings bent by pipes, and their inner width is suitable for sleeving the guardrail 7 and the sliding rods 5 and 6. The sleeved sliding rings 8 and 9 are firmly welded to the guardrail 7. The made guardrail 7, the upper sliding ring 8 and the lower sliding ring 9 are integrally sleeved into the left sliding rod 5 and the right sliding rod 6, and the sleeved sliding rods are welded to the platform 3 at the corresponding position at the entrance of the ladder 2. After the sliding rods are welded, a lower limit stop 10 is welded at a safe distance below the platform surface, so that the sleeved lower sliding ring 9 is located on the lower limit stop 10. Finally, the top of the ladder handrail 1 is welded to the sliding rod and located below the upper sliding ring 8 as the upper limit stop of the guardrail 7. This is the position where the operator manually lifts the guardrail. Note that when arranging the overall layout, the height for people to enter below after lifting should not be less than 1 m.
[0019] The sliding guardrail is adopted as the safety protection for the entrance of the upper platform of the ladder, so that there is no gap in the platform accessed through the ladder at a high place, and there are guardrails all around, thus reducing the risk of working at heights; the manual operation is flexible and convenient, time-saving and labor-saving, and does not affect the normal work at all; the structure is simple and easy to manufacture, the manufacturing cost is low, and the maintenance and replacement are convenient; the principle is simple, the safety protection function is remarkable, and it can be widely promoted and used.
[0020] The technical solutions provided by the embodiments of the present invention have been introduced in detail above. Specific examples are used in this article to elaborate on the principles and implementation manners of the embodiments of the present invention. The descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention.
