Detailed Description
Referring to fig. 1, the embodiment of the falling protector for climbing the electric pole comprises a chain 1, a rope locking device 2 and two soft ropes 3, wherein the two soft ropes 3 are respectively fixed at two ends of the chain 1, the two soft ropes 3 are connected through the rope locking device 2, the two pieces of software and the chain 1 form a ring shape for holding the electric pole 4, and a safety belt hanging and connecting ring 5 is hung on the chain 1.
As shown in fig. 2 and 3, the rope locking device 2 includes a frame body 6, a locking wrench 7 and a safety pin 8, a through groove 9 with a U-shaped cross section is formed in the frame body 6 to allow the soft rope 3 to pass through, the through groove 9 includes an inlet end and an outlet end, a rope tying hole 10 is formed in one side of the frame body 6 at the outlet end of the through groove 9, the locking wrench 7 is rotatably arranged in the through groove 9, a safety bolt 11 is fixed in the middle of the locking wrench 7, the safety pin 8 is fixed in the through groove 9 and contacts with the safety bolt 11, and a wavy anti-slip groove 12 is formed in a contact surface between the locking wrench 7 and the soft rope 3.
As shown in fig. 4, the safety pin 8 comprises a hollow tube 13, a pin body 14, a pressure spring 15 and a handle 16, the hollow tube 13 is fixed in the through slot 9, a transverse slot 18 along the axial direction is formed in the hollow tube 13, the rear part of the pin body 14 is arranged in the hollow tube 13, the front part of the pin body 14 extends out of the hollow tube 13 and contacts with the safety pin 11, the handle 16 passes through the transverse slot 18 and is in threaded connection with the rear part of the pin body 14, the rear end of the hollow tube 13 is in threaded connection with a sealing block 17, the pressure spring 15 is arranged in the hollow tube 13 between the sealing block 17 and the pin body 14, the front part of the pin body 14 is provided with an inclined plane, the safety pin 11 contacts with the inclined plane to retract the pin body 14 into the hollow tube 13 in preparation for locking of the locking wrench 7, the safety pin 11 passes through the safety pin 11 at a position, and after the safety pin 11 passes through completely, the front part of the pin body 14 extends out to block the, preventing the lock wrench 7 from rebounding.
When the device is used, an operator in an electric power department fixes the safety rope on the safety belt hanging ring 5, then sleeves the device on an electric pole 4 needing to climb, moves the device to a certain height along the electric pole 4, tensions the other soft rope 3, then moves the locking wrench 7 to be contacted with the other soft rope 3 through the antiskid groove 12, the soft rope 3 is clamped between the locking wrench 7 and the bottom of the through groove 9, the safety bolt 11 is propped against the pin body 14 at the moment, the locking wrench 7 is prevented from rotating through the pin body 14, so that the operator in the electric power department can safely move upwards the locking wrench 7, when the height of the device on the electric pole 4 needs to be adjusted, the pin body 14 is contracted towards the hollow tube 13 by pulling the handle 16 to be separated from the safety bolt 11, the locking wrench 7 rotates to loosen the other soft rope 3, so that the position of the whole apparatus on the pole 4 can be adjusted.
