2results about How to "Reduces bending damage" patented technology

This invention relates to a bidirectional protection device and method for lifting beams and wire ropes. The device includes at least one protection module, comprising an upper protection seat and a lower protection seat, which are fixedly connected by a plug-in mechanism. The upper protection seat has a rebar clearance groove; the lower protection seat has a connecting groove that connects to a wedge-shaped connecting plate and is equipped with the plug-in mechanism. The upper and lower arc-shaped rope support grooves together form a wrapping channel, which has an arc-shaped groove in which an arc-shaped slider is installed. Both the upper and lower protection seats have inner grooves containing elastic damping mechanisms. The inner walls of both the upper and lower protection seats are covered with a biomimetic damping protective layer. This invention converts tensile force into self-increasing clamping force through wedge self-locking, is adaptable to various types of precast concrete beams, is easy to assemble and disassemble, reusable, and equipped with standardized protection methods, significantly improving lifting safety and construction efficiency.

The utility model relates to the field of washers, in particular to a firm saddle-shaped washer which comprises a central part and edge parts, the edge parts are smoothly and fixedly arranged on the two sides of the central part, a central hole is formed in the central part, the central part is bent, the edge parts are also bent, each edge part comprises a bent section, and the bent sections are connected with the central hole. The bending section is connected with the central part, and the difference between the width of the central part and the diameter of the central hole is smaller than the width of the bending section. According to the utility model, the central part and the edge part are arranged, so that the bending section at the edge part can bear larger lateral force, and the possibility of bending damage in the transportation process is reduced; in addition, the horizontal section is arranged on the edge part, so that the possibility that the gasket is stressed, bent and damaged in the installation process due to the fact that the end part of the edge part is clamped with the installation plane is reduced.
