Preferably, two pulleys are arranged in the clamping lock, the control rope is in contact with the circumferential surface of the pulleys and is fixedly connected with the top surface of the locking block through the guide of the pulleys.
An application method of an omnibearing safety belt comprises the following steps:
step one, wearing:
paste the back pad at the operation personnel back, be connected the belt with the belt head for the waistband fastening is on operation personnel waist, then with two baldrics in the front cross arrangement, the insurance is detained and is shouldered the fixed orifices and be connected, through I adjustment shoulder belt length of letter i, makes shoulder and operation personnel health laminating. The leg winding pad is fixed on the leg of the operator through the connection of the fastening belt and the belt clip, and the hip pad corresponds to the hip of the operator. Then connecting a safety lock at one end of the enclosing rod belt with a fixing hole of the enclosing rod belt;
step two, climbing a pole and performing aerial work:
the utility model discloses a pole, including the pole, the safety lock of pole area other end is connected with the pole area fixed orifices of enclosing, if the pole area length is too little, simultaneously through II adjustment intermediate zone lengths of letter of a chinese character's knot, ensures that the antiskid cover is in pole area intermediate position always, and the sawtooth antiskid face on the antiskid cover contacts with the pole. When frost exists on the telegraph pole, the power switch is pressed to enable the heating wire to pass through, the anti-skid sleeve is heated, and the frost on the telegraph pole is melted. In the initial state, the lock rod is positioned at the leftmost end under the pushing of the thrust spring IV, and the lock groove is in an open state. When reaching the wire pole top and carrying out high altitude construction, with the locked groove card on the crossbeam at wire pole top, then promote the locking lever, because the locking lever top surface is the inclined plane of high left low right low, consequently the locking piece is extrudeed to the locking piece, make the locking piece retraction to the locking piece intracavity portion, when the locking piece groove corresponds with the locking piece chamber, the locking piece pops out the locking piece chamber under thrust spring III promotes, the locking piece inserts the locking piece inslot portion, deadly the locking lever lock, make the kayser hang on the crossbeam at wire pole top. A section of safety pipe rope is pulled out from the interior of the wire box, the length of the safety pipe rope positioned outside the wire box is convenient for operators to work aloft, then the positioning rod is rotated, so that the clamping block is inserted into the clamping block groove, the tail end of the positioning rod is inserted into the positioning hole under the pushing of the thrust spring II, and the rotating wheel is prevented from rotating during the work aloft;
step three, rod descending:
before the telegraph pole is ready to be put down, the positioning rod is lifted and rotated, so that the clamping block is separated from the clamping block groove, the positioning rod is separated from the positioning hole, and the rotating wheel can rotate freely. Then the wire pole is descended, along with the descending of operation personnel, the safety pipe rope is rolled out from the inside of the wire box, the wire wheel is driven to rotate, and the rotating speed of the wire wheel is measured by the rotating speed sensor. If the personnel fall down the wire pole in-process carelessly, the line box is rolled out fast to the safe pipe rope, and line wheel rotational speed accelerates, and when speed sensor measuring rotational speed was higher than safe rotational speed, controlling means controlled the electro-magnet circular telegram, and thrust spring V's thrust is overcome to the check rod, inserts chuck inslot portion, fixes line wheel through the chuck, and the length of restriction safe pipe rope avoids the direct decline of operation personnel at ground, causes the casualties. The stop rod can drive the chuck to extrude the thrust spring I after being inserted into the chuck groove, impact energy is buffered, and hard collision between the stop rod and the wire wheel is avoided. Meanwhile, the control device controls the electromagnetic valve to be opened, high-pressure air in the high-pressure air cylinder tank flows into the waistband, the back cushion, the hip cushion, the thigh rear protection pad and the leg winding pad, so that the waistband, the back cushion, the hip cushion, the thigh rear protection pad and the leg winding pad are expanded, if the safety pipe rope is broken, an operator falls down to the ground, and the expanded waistband, the back cushion, the hip cushion, the thigh rear protection pad and the leg winding pad can also play a role in protecting the operator;
step four, taking off the clamping lock:
after the operating personnel safely arrived the bottom surface, control the rope through controlling the pulling of hole, control the rope after the pulley direction and draw in the locking piece intracavity portion, the locking lever removes left under thrust spring IV's promotion, opens the locked groove, and the kayser drops from wire pole top crossbeam, then rotates the runner and retrieves the inside wire receiving chamber with safe pipe rope.
Compared with the prior art, the invention has the following beneficial effects:
(1) have two enclosing pole areas, step on the pole in-process and meet the barrier, can guarantee an enclosing pole area both ends and waistband fixed connection, improve factor of safety.
(2) The protective coat is fixed on the body of an operator through the shoulder straps, the waist belt and the leg winding belts, the contact area of the body of the operator is large, the operator does not feel tight when using the protective coat, and the comfort of the operator is improved.
(3) The safety pipe rope is provided with the clamping lock, so that the clamping lock can be clamped on a cross beam of a telegraph pole when climbing to the top of the telegraph pole, and double protection is provided for operators.
(4) The cover is equipped with the antiskid cover that has the heating function on the surrounding rod area, and when there was frost on the electric wire pole surface, effectual deicing provided better safeguard effect.
(5) When the pole is lowered, the clamping lock is always clamped on the cross beam of the telegraph pole, if an operator falls carelessly, the stop rod is automatically inserted into the chuck groove, the rotating wheel is prevented from continuously rotating, the safety pipe rope which is leaked outside the wire box is prevented from being prolonged, and the operator is prevented from directly falling onto the ground.
(6) When the operation personnel fall, the protection overcoat is aerifyd the inflation, if the disconnection of safe pipe rope, the operation personnel fall to the ground, and the impact energy can be cushioned to the protection overcoat after the inflation, provides the protection for the operation personnel.
(7) Through wireless module, managers can refer to operation personnel operation data on the computer, for example high altitude construction time, operation height above sea level and whether take place to fall, conveniently in time organize the rescue.
