Better, so that the safety of staff at work is higher, one end of fall prevention rope is fixed on the anti-falling rods of side, fall prevention rope
The other end be provided with fixed device, the other end of fall prevention rope passes through fixed device and the anti-falling rods of the other side connect, rotation electricity
The axis of machine and Rotational Cylindrical composition is located in the plane of two anti-falling rods composition, and two rotary electric machines are separately fixed at base side
Both ends, Rotational Cylindrical is connected with the output end of rotary electric machine, and anti-falling rods are arranged in Rotational Cylindrical, and Rotational Cylindrical is cylindrical shape, turns
High stability when dynamic motor drives Rotational Cylindrical rotation, increases safety, when specific operation, first passing through mobile devices 5 will be high
Working platform drives to suitable position, and then staff enters on workbench, restarts lifting device 4 and is increased to conjunction
After suitable height, starting is located at two rotary electric machines on same side, and the output end of rotary electric machine rotates certain angle, from
And drive Rotational Cylindrical while rotating, Rotational Cylindrical rotation drives anti-falling rods rotation, so that being between anti-falling rods and base side
Certain suitable protection angle, the fall prevention rope between two anti-falling rods play effective protective action；Fixed device packet
Fixed plate 10 and limit plate 9 are included, is fixedly connected at the center of fixed plate with the other end of fall prevention rope, the upper and lower ends of fixed plate are set
It is equipped with limiting slot 12, limit plate is provided with interval trough 13, the shape and fall prevention rope of interval trough at the center of fixed plate side
The other end match, there is the second gap, the upper and lower ends of limit plate are located at limit between interval trough and the other end of fall prevention rope
In the slot of position, there is gap between the sides of limit plate upper and lower ends and limit groove bottom, be provided on the anti-falling rods of the other side with
The limit hole 8 that fixed device matches is connected between the side and limit groove bottom of limit plate upper and lower ends by anti-dropout spring
11 are connect, and the quantity of anti-dropout spring is at least one, so that it is not easily to fall off between limit plate and fixed plate, and fixed dress
Set be inconjunction with fall prevention rope across limit hole simultaneously not to fixation device active force when, anti-dropout spring is automatically by limit plate toward separate
Fixed plate direction is mobile and stabilized, so that the connection of fall prevention rope and anti-falling rods is more firm, not easily to fall off, the diameter of limit hole
It is slightly less than the maximum gauge of fixed device, limit plate is moved toward limit groove bottom direction fixed plate and limit plate active force
It is dynamic, while being spaced groove bottom and overcoming the second gap mobile toward fall prevention rope direction, so that the maximum gauge of fixed device is less than limit
The diameter in hole is inconjunction with fall prevention rope across limit hole so as to fix device, then not to fixed device active force, so that
Limit plate is mobile toward separate fixed plate direction under the action of anti-dropout spring, so that the maximum gauge of fixed device is greater than limit
The diameter in hole so that fall prevention rope is fixed between two anti-falling rods, and controls tearing open for fall prevention rope by fixed device
Fill very convenient, when the side of pedestal divider gate is arranged in anti-fall device, fall prevention rope will often be torn open with the opening and closing of divider gate
Dress, thus it is very quick with fixed device.
