Description
Technical Field
The invention relates to the field of overhead working tools used in overhead ground wire reinforcement construction, in particular to a double-pulley non-directional pulley and a use method thereof.
Background
In a power transmission line overhead ground wire reinforcing operation site, an operator rides an overhead ground wire flying car to enter and exit a ground wire damage point is a daily procedure, and currently, the operator is pulled to a repairing operation point to use a pulley, particularly in a section with large arc hammer height difference of mountain big-mountain and ground wires, the operator rides the ground wire flying car and is difficult to return to the overhead ground wire suspension point by himself. Under the condition that a pulley is not used, a traction rope is required to be used for carrying the flying car when people get in and out of the overhead ground wire, when the flying car slides to a position 30-50 meters away from the pole tower, the weight and traction force of the traction rope often increase the weight of ground wire operators, so that the ground wire operators feel that the ground wire operators are pulled backwards, even the operators need to use the own force as power for driving the flying car to advance, and at the moment, the operators are tired without reaching the position of an operation point, and cannot perform reinforcement operation any more, so that the operation failure is the main reason. Although many improvement measures are adopted, the influence of far friction force and gravity cannot be avoided, and the situation of long-distance reinforcement cannot be realized. The existing overhead ground wire reinforcement defects are as follows: 1. the overhead ground wire arc hammer and the ground wire hanging point have large height difference, and along with the change of the gravity center of a traction rope used for the overhead ground wire galloping, particularly when in long-distance operation, the galloping sometimes slides unsmoothly, and the ground wire is required to be pulled manually, so that the bearing capacity of the ground wire is increased, the falling risk of ground wire operators and the galloping is increased, and potential safety hazards exist. 2. The overhead ground wire reinforcing operator slides along the way of the galloping machine, so that the labor intensity is high; 3. the farther the working personnel and the overhead ground wire galloping slide, the more the personnel are needed to be matched at the tower head end of the pole tower, the time and labor are wasted when the hauling rope is wound and unwound, and the labor intensity is particularly high. 4. The safety production operation cannot be guaranteed, and because the ground wire reinforcing operator slides by a traction rope snub in the process of sliding the overhead ground wire to an operation point, the short waist rope on the operator is buckled on the overhead ground wire and the galloping, and the safety of the operator is only guaranteed by the undamaged tension of the overhead ground wire, so that the operation requirement cannot be met. The existing improved complete sliding equipment has the defects of high manufacturing and processing cost, inadaptation of operation to a certain special terrain requirement, complex working procedure and the like.

Step 1, carrying a double-pulley non-directional pulley by ground wire operators, erecting ground wire gallows on the ground wire, and after riding, opening an opening bracket of the double-pulley non-directional pulley, and installing the opening bracket on the ground wire at one advancing side;
step2, connecting a fixed rope at the connecting part of the double-pulley non-directional pulley, connecting one end of a traction rope with a ground wire galloping, and vertically placing the other end of the traction rope below the ground wire together with the fixed rope through the upper part of the traction pulley;
And 3, dragging the pulley non-directional pulley to move forwards on the ground wire by the wire operator from the lower part of the ground wire through the fixed rope, tightening the fixed rope after reaching the target position, and pulling the traction rope so as to drive the ground wire to fly forwards.
The invention has the following beneficial effects:
1. The galloping is pulled and sent steadily, and in the ground wire reinforcement process, the ground wire arc hammer height difference that meets is great can change the position at galloping both ends, lets the cooperation personnel at wire end suitably adjust the distance, utilizes the principle of assembly pulley, avoids ground wire operating personnel to consume a large amount of physical stamina.
2. The double-pulley non-directional pulley has the advantages that the working efficiency is reliable, the stability of the double-pulley non-directional pulley is good, the pulley slides on the overhead ground wire safely, and the pulley is matched with personnel to pull the flying car and the personnel to slide through the pulley block, so that the problems that the pulling rope of the flying car is too heavy, the working distance is not far enough and the like are solved, and the working efficiency is improved compared with the working mode of the traditional method.
3. The operation speed is improved, the wire operators cooperate with the ground wire operators on the wires to pull and send the ground wire operators, on one hand, the weight born by the ground wire operators is reduced, on the other hand, the operation distance can be randomly adjusted, on the other hand, after the ground wire reinforcing operation is finished, the operation traction rope can be conveyed to the ground end by utilizing the pulley block, the personnel at the ground end can retract the traction rope, and the operation strength of the wire end cooperation personnel is reduced.
4. The labor intensity of workers is greatly reduced, a plurality of transmission ropes and traction ropes are not required to be manually moved and lifted, the operation intensity of tail rope workers is relieved through free adjustment of pulleys.
