A climbing protection method of a personal protection device for climbing poles of a power transmission line comprises the following steps:
a: the gas storage pressure of the gas storage tank 8 is ensured to be 0.4-0.8 Mpa, and the box body 9 is pushed to a proper position and then fixed.
A pressure gauge can be assembled on the tank body of the gas storage tank 8, or the exhaust pressure is checked periodically, the exhaust pressure is guaranteed to be 0.4-0.8 Mpa, the safety rope cannot be clamped due to too low pressure, the safety rope is possibly clamped due to too high pressure, and the protection effect cannot be achieved.
B: the leading end of the safety rope 29 is removed from the spool 12, threaded through the first sleeve 14, led out of the second sleeve 15 and passed through the fixed pulley 28.
Before power-up, the safety rope 29 is pulled out from the leading end of the wire spool 12, passes through the first sleeve 14 and the second sleeve 15, then the end passes through the fixed pulley 28, and after passing through the fixed pulley 28, the tail end of the safety rope 29 is fixed on the switch device 40.
C: a fixed pulley 28 threaded with a safety rope 29 is hung on a cross arm 27 of a telegraph pole 30 through an unmanned plane or other means, and a safety belt connected with the tail end of the safety rope 29 is tied on an operator 31.
D: the operation of ascending a height after the power transmission, radar 1 gathers operating personnel 31's position in real time, then gives central processing unit 4 through communication bus 2 communication, central processing unit 4 calculates the data of gathering to control step motor 13 through step driver 11 according to the data of gathering and rotate, make safety rope 29 with the same speed removal of operating personnel 31, specifically divide following several kinds of condition:
d1: as mentioned above, the central processing unit 4 performs operation according to the data collected by the radar 1, and when v is greater than or equal to 0, the central processing unit 4 controls the stepping motor 13 through the stepping driver to control the safety rope 29 to move at the speed v, which is divided into two cases:
d11: when the shaft diameter of the stepping motor 13 is the same as the diameter of the wire spool 12 connected through the shaft sleeve 35, the cpu 4 causes the stepping driver 11 to control the stepping motor 13 to rotate at the same speed v, so as to pull the safety rope 29 to move upward along with the operator 31 at the same speed v;
d12: if the shaft diameter of the stepping motor 13 is different from the diameter of the spool 12 connected through the bushing 35, assuming that the shaft diameter of the stepping motor 13 is R, the shaft diameter of the spool 12 is R, and the rotation speed of the stepping motor is u, then if the speed of the safety rope 29 is v, the rotation speed of the stepping motor is:
u＝R/r*v； (3)
the cpu 4 controls the step driver 11 through the communication bus 2, so that the step driver 11 controls the step motor 13 to move at the speed u calculated by the formula (3), and the safety rope 29 moves upward along with the operator 31 at the same speed v.
D2: when v < 0 or a certain time SnWhen there is no signal or the receiver 6 receives a fault signal, the following situations are distinguished:
d21: the operator 31 slides down during the climbing operation, i.e. when v < 0, SnWhen there is a signal and the magnetic switch 33 is not turned on, the CPU 4 receives S from the radar 1nThe signal judges that v < 0 is that the moving speed of the operator 31 is downward, at the moment, although the magnetic switch 33 is not switched on, the operator 31 is possibly in risk of falling, at the moment, the central processor 4 communicates with the step driver 11 through the communication bus 2, so as to control the step motor 13 to stop, meanwhile, the central processor 4 controls the electromagnetic valve to act through the control line 3, after the electromagnetic valve 25 is electrified, the electromagnetic valve 25 is opened, the compressed air entering the electromagnetic valve 25 from the main air path 5 enters the air inlet 20 of the air cylinder 23 through the air inlet pipe 21, and the air cylinder is pushed to push the air cylinderThe ejector rod 24 of the ejector rod 23 moves forwards, the gas in the cylinder 23 returns to the electromagnetic valve 25 from the gas outlet 18 through the gas outlet pipe 19, the concave block 17 on the ejector rod 24 moves forwards along with the gas, the convex block 16 clamps the safety rope 29 in the middle, and the safety rope 29 can pull the operator 31, so that the protection effect is achieved;
d22: when the operator 31 does not wear the safety belt or the safety belt inner switching device 40 is damaged during the pole climbing work, SnNo signal, in this case, SnIf no signal is available, the central processing unit 4 cannot perform operation, and thus cannot perform the safety protection function, and the central processing unit immediately performs the safety protection action in the same manner as D21;
d23: when the magnetic switch 33 detects the magnetic material block 45, the receiver 6 receives a fault signal, in this case, the extension spring 38 is already in the state of maximum extension length, which indicates that the operator 31 is overweight or the operator 31 has too much overload, or the operator 31 is pressed above during ascending operation, so that the safety risk is higher, in this case, the cpu immediately performs the safety protection action in the same manner as D21;
d24: when the magnetic switch 33 detects the piece of magnetic material 45, the receiver 6 receives the fault signal and the signal disappears, in this case the tension spring 38 deforms and breaks after reaching the maximum tension length. Considering that uncertain factors easily exist in the signal transmission process, sometimes when the operator 31 falls suddenly in an emergency, if the central processing unit 4 is just interfered, the protection action cannot be performed, at the moment, the tension spring 38 is just stretched and broken, and at the moment, the redundant safety rope (29) designed between the first insulation board 41 and the second insulation board 42 tensions the operator 31 to play a protection role.
According to the protection device for the ascending operation of the power transmission line, after radar ranging is adopted, the ascending operation condition of an operator is accurately calculated and judged through the central processing unit, the operator can timely and rapidly act at the moment of falling, and the safety rope is clamped through the air cylinder to protect the operator; the utility model provides a transmission line operation protector of ascending a height because the safety rope all coils on the wire reel, and usable distance is long, can be suitable for the wire pole of multiple not co-altitude, and this device is portable to be fixed simultaneously, convenient to use, and the commonality is strong.
