Description

Self-rescue tool for high-altitude operation

Technical Field

The application relates to the technical field of safety protection for high-altitude operation, in particular to a self-rescue tool for high-altitude operation.

Background

At present, a large amount of overhead operation is contained in a power transmission, transformation and distribution work site in an electric power system, the risk of accidents caused by the fact that operators are trapped at high altitude is increased along with the increase of operation frequency, and when the electrical workers carry out the overhead operation, the basic risk is the risk caused by the fact that the electrical workers fall at the high altitude and hang on a line or a component after falling. When a power worker works or moves on equipment such as a pole tower, an insulator, a ground wire and the like, the power worker can accidentally fall due to emergencies such as physical conditions, equipment use, working environment, natural conditions and the like, and is suspended in the air under the protection of the anti-falling protection rope.

When falling, the intervention time can be longer because external rescue forces such as fire brigades and folk rescue brigades cannot arrive at the site at the first time. At this moment, the safety belt bears the weight of the whole body, particularly, the thigh part can be tightened by the leg belt in the safety belt, blood circulation is affected, trapped people cannot finish self rescue, suspension wounds (safety belt suspension syndrome) can be caused by overlong time, and the obstructed blood circulation and brain hypoxia suffocation can be caused by airway blockage in severe cases.

Referring to fig. 1-7, the embodiment of the application provides a self-rescue tool for high-altitude operation, which comprises a first self-rescue rope 11 and a second self-rescue rope 13, wherein a first end of the first self-rescue rope 11 is provided with a unidirectional moving structure 17, the unidirectional moving structure 17 is used for being connected with a falling-prevention protection rope 10, and a second end of the first self-rescue rope 11 is used for being connected with a safety belt; a unidirectional moving structure 17 is arranged at the first end of the second self-rescue rope 13, the unidirectional moving structure 17 is used for being connected with the anti-falling protection rope 10, and a pedal ring 15 is arranged on the second self-rescue rope 13; the first end of the first self-rescue rope 11 and the first end of the second self-rescue rope 13 are close to each other.

In this embodiment, first end of rope 11 and the second of saving oneself rope 13 is the one end of being connected with the protection rope 10 that falls of preventing, and the one end of not being connected with the protection rope 10 that falls of preventing is its second end, and the safety rope that the protection rope 10 that falls was equipped with for high altitude construction can be connected with the safety belt through this rope when accidentally falling, avoids personnel to fall completely. First rope 11 and the second of saving oneself in coordination with rope 13 for the personnel that fall can be connected with the one end of first rope 11 of saving oneself through the safety belt of wearing, and the other end through first rope 11 of saving oneself with prevent falling protection rope 10 and be connected, realize personnel's truck's stable state, the personnel that fall can save oneself the pedal 15 singles feet on the rope 13 through the second simultaneously and borrow the power, the body appearance of standing when hanging in midair becomes the position of sitting, avoids personnel to appear the safety belt and suspends syndrome in midair. Set up on the protection rope 10 of preventing falling through the alternating movement that makes progress and save oneself the unidirectional movement structure 17 of the first end of rope 11 and the second rope 13 of saving oneself, the personnel that fall realize alternate support center to support the atress through pedal circle 15, upwards climb gradually and accomplish saving oneself, then can convert the position of sitting rest into on the way in the climbing.

The unidirectional moving structure 17 is a connecting member and can only move in one direction, when the connecting member moves in the opposite direction, great resistance or locking can be generated, the backward movement of the connecting member is avoided, and secondary falling occurs, for example, a Prussian catch knot, a French catch, a gram (Beckmann) catch and other rope knots which can move in one direction are formed in a winding and knotting mode, or the existing mechanical structure such as a mechanical lifter, a unidirectional pulley, a unidirectional sliding lock and the like is adopted.

In one embodiment, as shown in figures 1 and 2, an embodiment is provided in which a Prussian grip is used as the unidirectional movement structure 17, the Prussian grip, developed from a change in the lacing knot, securely pulls the rope like a pinched fist upon a load; when the load is unloaded, the load can slide on the rope freely. When climbing along the rope, two Prussian knots are alternately used, when one bears a load, the other one can freely slide, in the embodiment, a person falling and hanging serves as the load, the Prussian knots can freely climb by alternately moving different Prussian knots, the Prussian knots adopt wear-resistant nylon auxiliary ropes with the diameter of 5 or 6 millimeters, and a 30-centimeter-long rope sleeve is connected through double fisherman knots to tie the Prussian knots with the best effect. The best braking effect is usually achieved by winding the rope three to four turns, and several more turns if the knot is still slipping.

In one embodiment, an implementation is provided with a mechanical riser as the one-way moving structure 17, which functions similarly to a prussian knot but is stronger, safer, faster and easier, the mechanical riser being provided with a cam or pawl design that allows the riser to slide in only one direction. The lifter is provided with a pull rod and a safety, the rope can be easily clamped into the lifter and can be prevented from falling off accidentally, hook and loop holes at the top end and the tail end of the lifter can be used for multiple purposes, such as hanging a backpack and the like, if no hook and loop hole exists, an iron lock needs to be hung in the lifter handle for operation, if the lifter is used in a cold environment, the type with a large handle opening needs to be selected, so that hands wearing gloves can be held, the mechanical lifter is similar to Prussian grabbing in the use in the embodiment, a support center is changed by utilizing self-rescue ropes connected with different mechanical lifters, when one self-rescue rope is used as a stress rope, the mechanical lifter arranged on the self-rescue rope is locked, the mechanical lifter on the other non-stress self-rescue rope can move, and climbing can be realized alternately.

In an embodiment, as shown in fig. 1 and 2, a connecting member may be disposed at the second end of the first self-rescue rope 11 for connecting with a safety belt, the connecting member may be an S-shaped connecting member 12, the second end of the first self-rescue rope 11 is wound and knotted in a hole of the S-shaped connecting member 12 to realize connection and fixation, the S-shaped connecting member 12 may be connected with the safety belt through a hook portion thereof for self-rescue after a person falls, and the connecting member may also be a latch, a hook, or the like, and it is sufficient to connect the first self-rescue rope 11 with the safety belt.

In one embodiment, as shown in fig. 1, an embodiment of a pedal ring 15 is provided, a three-hole connecting piece 14 is arranged on a second self-rescue rope 13 close to a second end of the second self-rescue rope, three holes are horizontally arranged on the three-hole connecting piece 14, the second self-rescue rope 13 crosses and penetrates the holes to extend in an S shape, so that the length of the second self-rescue rope 13 between adjacent holes of the three-hole connecting piece 14 can be adjusted, the pedal ring 15 is formed, and the second end of the second self-rescue rope 13 can be knotted to prevent falling. The three-hole connecting piece 14 can slide along the second self-rescue rope 13 to adjust the position formed by the pedal ring 15 and adapt to persons with different heights.
