Background
In the installation and maintenance operation at the top of the factory building, a large amount of high-altitude operation and edge operation exist, and operating personnel need to walk and work high above the top of the factory building. The high-altitude operation constructor needs to carry out safety protection to prevent the high altitude from falling, and carries out the walking of horizontal direction at the eminence, needs to set up the platform passageway that has the guardrail usually. Under the condition that the structure is not perfect or a platform channel is not convenient to build, constructors need to wear safety belts. The use of safety belt needs the hook point of activity, and current method utilizes the steel cable of interim setting as the hook point, because the factory building top does not have the steel construction, can't will adopt modes such as welding to carry out effective hookup with support and factory building structure, leads to the support to have intensity not enough, has great potential safety hazard, and construction safety is difficult to effectively guarantee. Secondly, when the steel rope is fixed, the steel rope is generally simply wound, or after winding, clamping or bolts are adopted to be rigidly and fixedly connected with the bracket. The steel rope and the bracket are easy to slide during simple winding, so that the horizontal protection steel rope has weak bearing capacity. And adopt centre gripping connection or bolted connection, in order to improve the effect of connecting, need compress tightly steel cable and clamping part or bolt, have higher requirement to operating personnel's strength, operating personnel that the strength is weak is difficult for accomplishing the reliable fixed to the steel cable, has certain potential safety hazard.
Therefore, it is necessary to achieve an effective coupling of the fixing brackets at the top of the plant, so as to provide a basis for the safety of the horizontal safety lines. Meanwhile, the steel rope needs to be firmly and conveniently fixed on the bracket so as to eliminate potential safety hazards.
