Detailed Description
1) The method is characterized in that the rope releasing traction force is correctly and reasonably calculated, a large-tonnage winch which can meet the production requirement is selected, the maximum traction force of the cableway during rope releasing is about 6.5 tons, and a 16-ton winch is used for traction.
2) Placing the steel wire rope on a cable tray frame at an upper station according to the rope outlet direction of the steel wire rope, leveling and compacting the bottom of the cable tray frame, slowly jacking the steel wire rope by using a jack, leaving 10-20 cm away from the original support, leveling a rope releasing central shaft, welding the cable tray frames at two sides by using channel steel or a circular pipe to form a firm whole, and stabilizing the cable tray frame by using 2 chain blocks of 5 tons in the opposite direction of the rope outlet direction of the steel wire rope; the brake device selects logs or brake tapes, 2 chain blocks of 5 tons are used for adjustment, and the effectiveness of the brake device is guaranteed; the brake operator is provided with the interphone, and can contact other related personnel at any time.
3) The freight cable traction cable with the diameter phi of 22 is used as a traction cable when the steel cable of the passenger ropeway is released;
4) lifting the cable releasing working rope with the diameter phi of 22 to a support cable supporting wheel on a line from a lower station to an upper station;
5) at the lower station, one end of a cable releasing working rope with the diameter phi of 22 is braided with a steel wire rope of the cableway (the braiding length of a carrying rope and the working rope comprises a core-spun length and an inserting length, the core-spun length is not less than 12 m, the inserting length is not less than 2 m, the joint position is protected by a steel anchor head), and the other end of the cable releasing working rope is wound into a winch roller with the length of 16T;
6) according to the actual situation on site, the nylon guide wheels are reasonably arranged so as to guide the cableway steel wire rope into a correct cableway line, so that the safety of releasing the steel wire rope is ensured, and meanwhile, the steel wire rope can be well protected;
7) after all the parts are ready and are checked to be correct, starting a 16T winch and drawing a phi 22 working rope to discharge a steel rope of the cableway;
8) in order to prevent the steel wire rope from rotating in the releasing process and change the lay length of the steel wire rope, a first anti-rotation is added for about 30 meters of the carrying rope before releasing, and a second anti-rotation is added for about 60 meters. It should be noted in particular that the antirotation is handled in time at the entrance and exit, the first antirotation device being removed when it reaches the entrance of the station. When the second anti-rotation device reaches the upper standing port, the second anti-rotation device is detached, and then the first anti-rotation device is installed on the other side. According to the position and the distance of the braided rope, the reversing wheel is arranged at a proper bracket position, so that the carrying rope has enough braided rope length after passing through the driving wheel at a lower station.
9) In the process of releasing the cable, a specially-assigned person is required to track the knitting heads of the two cables so as to strengthen the protection of the cableway steel wire rope;
10) and determining the actual braiding form and tensioning of the carrying rope according to the actual terrain condition.

The other side is hung on a pulley block on the basis of equipment, and the pulley block is hung on a clamping plate clip 35 meters upwards from the center of the driving wheel. And (3) penetrating and winding the pulley block by using a steel wire rope with the diameter of 11, wherein the multiplying power i is 20. And weights not lower than 60Kg are hung at the positions of the board card and the pulley block to serve as anti-reverse devices. The rope was tightened with a motorized winch to the designed tension. And after the tension force reaches the design tension force, the tension force stays for 72 hours. If the design tension drops, tensioning is performed again. And knitting is carried out until the tension is designed.
11) And (4) knitting construction is carried out on the cableway steel wire rope according to the standard requirement, and the carrying rope is knitted under the guidance of an outside engineer. And measuring the tension state actual length. And measuring the braiding length of the carrying rope, measuring the actual length required by braiding the carrying rope according to the tension state, and cutting off redundant parts. After the braiding length is measured, the length of the splicing section is divided, marked and braided. When the traction rope is tensioned in the knotting process, a special clamp which does not damage the traction rope must be used, and a common U-shaped rope clamp is strictly forbidden. Secondly, the length of the braided joint is not less than 1000 days for the freight cableway. For passenger ropeways, when the total filament number of the steel wire ropes is smaller than or equal to 114, the total filament number is not smaller than 1200 d; when the total filament number of the steel wire rope is more than 114, the total filament number is preferably (1300-1500) d.
