Recently, Gansu Provincial Federation of Trade Unions, Gansu Provincial Science and Technology Department, Gansu Provincial Department of Human Resources and Social Security jointly appraised and commended the Seventh Provincial staff outstanding technical innovation achievements. The "Optimum Design of Proximity Switch Sensing Method" declared by the Electrolytic Plant of Aluminum Corporation of China Liancheng Branch was awarded the second prize for excellent technical innovation of employees.
The proximity switch is a position switch that can be operated without mechanical contact with a moving part. When the object approaches the sensing surface of the switch to the action distance, no mechanical contact is required and no pressure is required to make the switch actuate, thereby driving the communication. Or DC electrical appliances or PLC control instructions.
"Optimum Design of Proximity Switch Sensing Method" is the first in China. It will change the proximity sensor sensing mode from "moving-static" or "static-moving" mode to "dynamic-static-static" mode, subverting the traditional proximity switch. Using the method, the failure of the proximity switch caused by the gap problem is fundamentally eliminated. Its design is novel, simple and practical, and can be promoted in all places where proximity switches are used.
“Optimized Design of Proximity Switch Sensing Method†has been used on 12 multi-function cranes in the Electrolytic Plant of China Aluminum Liancheng Branch. “Each year, 300 switches can be saved, spare parts costs can be saved by 120,000 yuan, and failure time can be reduced by 500 hours.†Calculated with 100 yuan per man-hour, labor costs are reduced by 50,000 yuan. Due to the reduced breakdown of overhead cranes, interference with production is avoided, and the efficiency of the electrolytic cell can be increased by 0.1% per year, and 380 tons of primary aluminum can be produced, creating a total value of 5.51 million yuan. The annual economic benefits will be 5.68 million yuan."
At the same time, this technical achievement has reduced the maintenance of the multi-function unit and ensured the personal safety of the maintenance personnel.
If the "optimized design of proximity switch sensing method" is applied in the entire electrolytic aluminum industry, according to 400,000 tons of aluminum, 12 sets of overhead cranes, there are 1000 multifunctional day cranes in China, and the spare parts cost will be 10 million yuan per year. . The value of failure reduction factors to the smooth operation of production is incalculable and has great promotion value. (Cai Yingke Zhang Yan)
Features: clevis shackle are made for installation in holes augered by power drillers. A retainer on the bottom holds the nut from the forged eye rod (sold separately) Application: A hole to the size listed on the table for the anchors is augered to a depth based on the rod length. The hole is undercut so the anchor is at a right angle to the guy. A rod trench is cut with a trenching tool or drilled with a small power auger to the guy angle. The width of the trench should be just sufficient to accommodate the rod. The rod is secured to the cross plate anchor and placed in the excavated hole and trench. The hole is then refilled and tamped.
Hot-dip Galvanized U Shackle/U Type Shackle Clevis are malleabe iron or casting steel, these cotter pins are stainless, the other parts are hot-dip galvanized.
They are used to connect insulator and electric power fittings on ultra high voltage transmission line.
