The fall arrester structure is divided into two parts: the outer structure and the inner structure. The external structure (that is, the part that can be seen by visual observation) includes the main part of the fall arrester: safety buckle, fall protection safety rope, rubber sheath, safety buckle. Internal structure (mainly refers to the internal components of the fall arrester): gear shaft, snap, coil spring or wire rope, fixed circlip, fixing screws, etc.
The high-altitude anti-dropping device is an individual anti-falling product used for climbing the upper and lower towers of high-altitude workers. It is a steel cable that fixes the anti-theft and anti-saw on the iron tower or steel tube tower and the electric power pole. The fall arrester is tested on-site by the acceptance team to ensure that the fall arrester is qualified before it can be sold offline.
The anti-drop device adopts the principle of eccentric action of the cam mechanism. When the connecting end of the locking cam and the seat belt is subjected to an external force due to the human body falling, the eccentric action of the cam mechanism causes the locking cam to quickly lock the cable, thereby preventing the person from falling. The safety fall arrester adopts rope type, reasonable structure, superior performance, easy installation, simple operation, safe and reliable, short sliding distance, low impact on human body, low cost, etc. It can be widely used in electric power industry and other industries. The anti-fall protection in the operation can eliminate the drawbacks of the current construction workers without protection during the process of getting up and down the tower, and provide safety for the ascending workers.
The high-altitude test should be carried out at the construction site and the high-altitude fall arrester is not faulty. First, cut off the main power. Connect the cable on the ground control button box to the terminal block marked “Falling Test” in the electrical box of the cage. Straighten the control cable on the ground control button box to prevent the cable from being pulled when the cage is lifted and lowered. After the cage is loaded with the rated load, turn on the main switch and press the “up” button on the ground control button box to raise the ladder cage by about 10m.
Press the button marked with “down” symbol, don't let go, when the brake on the motor is released, the cage will fall down. When the speed of the safety device is reached, the anti-drop device will move and the cage will stop smoothly. On the rail frame. If the fall arrester has not stopped the cage when it reaches 4m from the ground, immediately release the “down” button to make the brake speed differential fall arrester stop the cage to prevent the cage from appearing. Impact on the base phenomenon.
