technical field

The utility model relates to a ladder safety protection device, which belongs to the technical field of engineering equipment.

Background technique

In daily life or engineering work, people often use climbing ladders for climbing operations. Because of their lightness, ease of use, and diverse application scenarios, climbing ladders are widely used in various fields. For example, in the maintenance work of transmission lines and substations, electricians Often with the help of climbing ladders, various electrical equipment or circuits are repaired. However, compared with other climbing equipment, the safety of the climbing ladder is relatively low, and there are almost no safety protection measures. The climbing ladder is prone to sideslip, causing the operator to fall. And the accident that causes personnel to fall also takes place from time to time, and then causes casualty and heavy economic loss.

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides a ladder safety protection device.

The technical scheme of the utility model is as follows:

Adjust the angle for easy operation and adjust the ladder to the most suitable position on the climbing equipment.

According to the present utility model, preferably, both the traction rope and the safety rope are nylon ropes. The advantage of this design is that the nylon rope has strong bearing capacity, but also has toughness and flexibility. Compared with the steel wire rope, it is economical and practical, with low cost and convenient installation and use.

According to the present invention, preferably, a hook is provided at the end of the bow-shaped hoop, and the hook is connected with a spring, and the spring is also connected with the bottom end of the I-shaped bracket. The advantage of this design is that the hook structure at the front end of the bow hoop is used to hook the equipment to be climbed, and the bow hoop is adjusted by the traction rope during use. The setting of the spring is beneficial to control the traction force of the traction rope and facilitate the adjustment of the bow hoop s position.

The beneficial effects of the utility model are:

The safety protection device for climbing ladders of the utility model effectively solves the sideslip problem existing in the existing climbing ladders, and at the same time, the device also protects the workers, prevents the workers from accidentally falling, and protects personal safety and property safety; the design concept of the device Ingenious, simple and practical structure, easy installation, convenient use, remarkable effect, good economic and social benefits, worthy of popularization and application.
