Detailed Description
As shown in fig. 1, 2, 3, 4, the utility model provides a transmission line overhauls operation rope formula rope ladder, including a safety rope 6, install safety buckle 1 at this safety rope 6 top, install current conventional rope ware 2 of grabbing on the safety rope 6 of this safety buckle 1 below, install at least 2 such as 6, 8 or 10 pedals on this safety rope 6 of grabbing rope ware 2 below to the orientation of two adjacent pedals is opposite, thereby it conveniently climbs to distribute in turn left-right as shown in fig. 1, installs from locking-type couple 5 in this safety rope 6 bottom.
Wherein the pedal comprises a hard pole 4 and a section soft rope 3 of insulating material such as epoxy, and the soft rope 3 material is the same with safety rope 6, is right angled triangle after the pedal expandes during the use, and the one end of this hard pole 4 articulates on safety rope 6 and its other end passes through soft rope 3 and is connected with safety rope 6. The self-locking hook 5 comprises a U-shaped split ring 7, one end of the split ring 7 is fixed at the bottom of the safety rope 6, the other end of the split ring 7 is hinged in the middle of a locking handle 8, a limiting block is arranged beside the hinged point, the locking handle 8 is limited in the position shown in figure 4 after being opened, the locking handle 8 can only rotate anticlockwise, and a connecting hole is formed in the tail end of the locking handle 8 and used for connecting a balance weight or opening the locking handle 8 by using an insulating operating rod under special conditions such as jamming.
Example 1:
the utility model discloses a rope ladder is from last to down by safe buckle 1, detachable rope ware 2, rope formula rope ladder and gravity from locking-type wire couple (from locking-type couple 5) etc. parts constitution. When the rope grabbing device is used, the safety buckle 1 is arranged at the topmost end of the rope ladder and matched with the rope grabbing device 2 for use, and the rope ladder is anchored on a tower material of an iron tower. Specifically, after the bottom self-locking hook 5 is hung on a lead, the upper part of the safety rope 6 is wound around a tower material, and the safety buckle 1 is buckled into a hanging (through) hole on the rope grab 2. The relative position of the rope grabbing device 2 and the rope ladder is adjusted to a proper size, so that the rope ladder can be maintained at a certain tension degree, and the rope grabbing device 2 is locked.
Detachable rope ware 2 and the rope cooperation use of grabbing, the rope passes from grabbing 2 insides of rope ware, grabs rope ware 2 and uses adjustable rope ladder's length and rate of tension with the cooperation of safe buckle 1. The rope grabbing device 2 is provided with a spring self-locking structure, a rope is in a locking state in a free state, and the rope grabbing device 2 cannot move; after the self-locking spring force of the rope grabbing device 2 is overcome by manual operation of an operator, the rope and the rope grabbing device 2 can move.
Rope formula rope ladder main part is a safety rope 6, and the pedal that supplies the operation personnel to scramble is provided with in turn about 6 both sides of safety rope, and pedal and operation personnel sole contact part are hard material, and the back is accomplished in the installation of rope formula rope ladder, and the pedal can expand under the dead weight effect, and the operation personnel of being convenient for scramble. When the rope ladder is folded, the pedals can be automatically folded and folded only by inverting the rope ladder, and the whole volume is small after the rope ladder is folded, the space is not occupied, and the rope ladder is easy to carry.
The gravity self-locking wire hook is arranged at the lowest end of the rope ladder and used for hooking the wire from the lower part when the rope ladder is installed, and after the wire is hooked, as shown in figure 4, the left side of a locking handle 8 of the hook is pressed down to cause the wire to rotate anticlockwise so as to lock the wire under the action of self gravity, and the rope ladder and the wire are prevented from falling off.
The utility model discloses a use method and theory of operation are:
before the rope ladder is used, the rope ladder is rolled and folded, and an operator carries the rope ladder to the position of the iron tower cross arm at the upper end of the lead. The operating personnel select a proper anchoring point on the iron tower, and the safety retaining ring 1 bypasses the anchoring point to be connected with the through hole on the rope grabbing device 2, so that the rope ladder is fixed on the tower material of the iron tower. The rope ladder is opened, one end of the wire hook of the rope ladder is slowly lowered to the position of the wire, the wire hook is hooked from bottom to top through the position of the wire hook self-locking lever, the self-locking condition of the wire hook is checked, and the hook is ensured to be stable. The rope grabbing device 2 is used for adjusting the length and the rigidity of the rope ladder to ensure the rope ladder to be tightened. At the moment, after the backup protection measures are taken, the operator can climb up and down through the rope ladder. After the operation is finished, the operator firstly adjusts the length of the rope ladder through the rope grabbing device 2 to enable the rope ladder to be loosened. The operating personnel adjust the posture of the wire hook on the rope ladder on the tower, so that the dead weight switch of the hook is in an open state, and the hook is operated to be separated from the wire. The rope ladder is retracted and the safety buckle 1 is opened at the same time, so that the rope ladder is unfastened from the anchoring point. The rope ladder is folded and taken to the lower part of the tower.
