Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A safety base of an electric pole ladder climbing platform device is shown in figure 1, wherein a main body of the safety base is a base frame; one end of the upper part of the base is provided with two connecting lug plates which are welded on the base; the ear plate is connected with the crawling ladder by a ball locking pin; meanwhile, the ratchet rope winding device, the automatic rope winding tensioner and the lifting ring nut are arranged to provide falling safety guarantee, and the ratchet wrench is arranged to be configured to facilitate the use of the ratchet rope winding device.
As shown in fig. 3, when the electric pole ladder stand platform device is installed, the safety base is fixed to the bottom of an electric pole, the ladder stand is connected with the safety base through the ball locking pin, quick plugging and unplugging installation is achieved, the ladder and the base can move in the only direction, and the electric pole ladder stand platform device is more suitable for installation and fixation of the ladder stand.
Dispose safety base in the cat ladder bottom, safety base is earlier fixed firm with the pole bottom, and cat ladder and base pass through safe bolt effective connection, and the high strength metal steel material is selected to the bolt, like 304 stainless steel, and it has 300 KN's the cutting-off force can satisfy this extension ladder's demand completely, safety base and rope ladder are right angle form that is ninety degrees earlier, connect good the ladder is drawn up behind the safety bolt, directly just can fix on the pole, and this operation is safe convenient, labour saving and time saving.
Meanwhile, the safety base of the electric pole ladder platform device is also provided with the anti-falling system, the anti-falling system is used for preventing safety protection during accidental falling, once falling occurs, the anti-falling system can be locked on a rope to absorb the force generated during falling, and the life safety of operators can be effectively protected. The safety protection device is suitable for safety protection when a suspended workpiece is prevented from accidentally falling during lifting of the overhead travelling crane, can effectively protect the life safety of operators and the damage of the object of the suspended workpiece, and is applied to high-place operation places such as metallurgical automobile manufacturing, petrochemical engineering construction, electric power, ships, communication, pharmacy, bridges and the like.
The hanging point does not need to be replaced when the radius is used. When in normal use, the safety rope can freely stretch along with the human body. Under the action of the mechanism in the machine, the machine is in a semi-tense state, so that the operator has no traction feeling. In case of the falling due to the loss of feet, the pulling speed of the safety rope is obviously accelerated, and the locking system in the device automatically locks. The pulling distance of the safety rope is not more than 0.2 m, the impact force is less than 2949N, and no harm is caused to the disabled. And the work is automatically recovered after the load is relieved. The safety rope can be automatically recovered into the rope device after the work is finished, and the safety rope is convenient to carry. The falling protector adopts an original 'double-locking device' structure, is stable in locking, high in safety factor and good in reliability, and effectively solves the problem that the falling swing amplitude of the inclined operation is too large to impact other objects to cause accidents. The falling protector control system is made of special steel and is subjected to special treatment, so that the falling protector is light in weight, wear-resistant, corrosion-resistant and impact-resistant, and the shell is made of aluminum alloy, so that the falling protector is light in weight and is not aged.
