Falling-preventing safety protection device with adjustable work range

Abstract

The invention relates to a falling-preventing safety protection device with an adjustable work range. The falling-preventing safety protection device is characterized by comprising a safety rope (5);a detachable bidirectional self-locking rope grabbing device (6) is installed in the middle of the safety rope (5); the detachable bidirectional self-locking rope grabbing device (6) is connected witha collecting and releasing type speed difference falling-preventing device (8) through a buffer (7); a first detachable rope grabbing device (2) and a second detachable rope grabbing device (3) are further arranged on the parts, on the left side and the right side of the detachable bidirectional self-locking rope grabbing device (6), of the safety rope (5) correspondingly; and the first detachable rope grabbing device (2) and the second detachable rope grabbing device (3) are connected with safety hooks (1). By means of the falling-preventing safety protection device with the adjustable workrange, the safety protection device capable of meeting field work requirements and also capable of ensuring the safety of working personnel is put forwards according to work conditions of the electricrunning overall industry and problems existing in existing safety protection technologies and products.

Description

technical field [0001] The invention relates to an anti-drop safety protection device with an adjustable working range. Background technique [0002] In the electric power operation and maintenance industry, maintenance personnel need to frequently carry out high-altitude operations on the tower. In order to protect the safety of high-altitude workers, operators need to be equipped with safe and reliable protective equipment when working at high altitudes. [0003] Most of the existing safety protection equipment is "point" protection type. Before use, the safety protection equipment needs to be suspended on the tower material in advance. Limited by the working conditions on the tower, the suspension point of the safety protection equipment on the tower is not an ideal area , The operator needs to protrude the suspension point horizontally for operation. Once a fall occurs, the operator will swing substantially around the suspension point, which is prone to the risk of secon...

Problems solved by technology

[0003] Most of the existing safety protection equipment is "point" protection type. Before use, the safety protection equipment needs to be suspended on the tower material in advance. Limited by the working conditions on the tower, the suspension point of the safety protection equipment on the tower is not an ideal area , the operator needs to protrude the suspension point horizontally to carry out the operation. Once a fall occurs, the operator will swing around the suspension point in a large way, which is prone to the risk of secondary impact (tower material) or electric shock

In addition, some safety protection equipment has a fixed length, which may cause excessive fall height difference and excessive fall impact force, which may cause physical damage to operators

In addition, the above-mentioned safety protection measures greatly limit the activity radius of operators, which brings great limitations to the maintenance of transmission lines.
