Description

Technical Field

[0001] The invention relates to the technical field of falling self-rescue, in particular to a portable high-voltage transmission line falling self-rescue device. Background Art

[0002] In order to prevent aerial workers from falling at a certain height and position, workers need to wear safety belts when climbing and working at heights. During normal line maintenance work, due to the constraints of the working radius on the conductors and insulators, accidents such as stepping on empty space and deviating from the right side may occur, resulting in high-altitude fall accidents. After the fall, the safety belt extends, causing the human body to fall a long distance below the conductor, and the success rate of the fallen person using his own arm strength to rescue himself is 0%. In addition, there are many disadvantages in the method of relying on others for rescue. The rescuers have no reasonable force points, which seriously restricts the success of high-altitude self-rescue. Combined with the analysis of previous cases, after the staff fell from a high altitude, the success rate of his rescue can be guaranteed, but the rescue time is as long as 40 minutes, which poses a great threat to the personal safety of the rescuer and the rescued. For ordinary people, the best rescue time should be controlled within 15 minutes. Up to now, there is no reliable method that can effectively and quickly solve the problem of self-rescue of high-voltage transmission line workers after falling;

[0003] When the high-voltage transmission line fall self-rescue device is in use, it is impossible to clamp and fix the rapidly descending safety rope, which causes the rapid descent of the safety rope to easily cause the rope to break or affect the self-rescue of the workers. At the same time, when the high-voltage transmission line fall self-rescue device is in use, it is impossible to limit the reeling or unreeling of the safety rope, which causes the safety rope to easily deviate and shake when reeling or unreeling, affecting the safety of the safety rope when in use. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides a portable self-rescue device for falling from a high-voltage transmission line. When the first safety rope is unwinding or rewinding, the ball is affected by the friction of the rewinding or unwinding of the first safety rope so that the ball can move inside the traction block. The speed sensor is used to detect the speed of the first safety rope when it is rewinding or unwinding. When the speed detected by the speed sensor exceeds the specified speed, the speed sensor can transmit a signal to the electric push rod, which is started so that the second fixed plate can be pushed to one side. When the second fixed plate is moving, the second fixed plate can drive the fitting seat and the protrusion to move toward the surface of the traction block together, so that the protrusion can fit with the surface of the first safety rope. When the protrusion fits with the surface of the first safety rope, the first safety rope can fit with multiple rubber rods. Through the continuous movement of the protrusion, the protrusion can push the first safety rope to the concave part of the traction block for squeezing, and the protrusion of the traction block can be fitted into the interior of the fitting seat through the opening, so that the protrusion and the fitting seat can fit together. The seat and the traction block can squeeze and fix the first safety rope in time, so that the first safety rope can stop being wound or unwound, thereby preventing the device from rapidly falling and causing danger when the staff is in danger. The elasticity of the first spring is utilized to make the first safety rope wound on the surface of the rope pulling roller fit with the squeezing roller. The fit between the first safety rope and the squeezing roller is utilized to make it possible to squeeze the first spring by the movement of the cross plate, and according to the winding diameter of the first safety rope, the squeezing force of the first spring can be reduced, so that the squeezing roller can fit and squeeze the first safety rope wound on the surface of the rope pulling roller in real time. When the first safety rope is in use, the first safety rope can fit with the surface of the smoothing roller, and the limiting roller can be used to limit the first safety rope fitted on the surface of the smoothing roller, and the squeezing of the squeezing roller can be used to make the first safety rope less likely to deviate when in use, thereby improving the safety of the first safety rope when in use, etc., solving the problems of inconvenience of self-rescue when the safety rope falls rapidly and easy deviation when the safety rope is wound or unwound.
