Problems solved by technology

[0003] The safety fence that people often use at present is composed of a column with a base and an elastic belt between the two columns. When arranging a safety fence at a power construction site, the elastic belt is manually retracted. When the isolation area is relatively large, it will be greatly increased. The labor intensity of the staff to place and install the safety fence on site will cause a lot of waste of labor time in the early stage of construction, and even affect the construction progress

Abstract

The invention discloses a safety rail capable of automatically winding and unwinding a warning belt. The safety rail comprises two rail stand columns and the warning belt, wherein the warning belt is stretched between the two rail stand columns, each rail stand column comprises a rotary shaft and a shaft sleeve, each rotary shaft is arranged in the corresponding shaft sleeve, the upper end and the lower end of each rotary shaft are fixedly arranged in the corresponding shaft sleeve through bearings, the lower end of each rotary shaft is connected with a drive motor, fixing casings for fixing the motors are arranged outside the drive motors, the lower ends of the shaft sleeves are fixed on the fixing casings, a supporting frame mechanism used for standing on the ground is arranged on the outer side of the lower end part of each fixing casing, and the warning belt winds around the rotary shafts. The rotary shafts are controlled by the motors to rotate, the purpose of automatically winding and unwinding the warning belt is achieved, and the work efficiency of workers carrying the safety rail and setting a protection area is improved effectively.

Description

technical field [0001] The invention relates to the field of safety protection equipment in the electric power industry, in particular to a safety fence that can automatically retract and retract a warning tape. Background technique [0002] The safety fence is usually used as a safety protection tool for the operation, maintenance and construction of the electric power industry. As an obstacle to prevent other personnel from entering the isolation area, it can be seen that the safety fence plays a vital role in ensuring the safety of on-site workers. [0003] The safety fence that people often use at present is composed of a column with a base and an elastic belt between the two columns. When arranging a safety fence at a power construction site, the elastic belt is manually retracted. When the isolation area is relatively large, it will be greatly increased. The labor intensity of the staff to place and install the safety fence on site will cause a lot of waste of labor t...
