Further, threads are arranged at two ends of the steel wire rope.
The beneficial effect of this scheme lies in: thereby be convenient for fixed wire rope nut lets wire rope better connection go up safety cover and lower safety cover, simplified the installation step, it is simpler and more convenient to make the installation, has also made things convenient for the dismantlement, does benefit to and detects the maintenance to flange joint department.
Further, the protective cover comprises a protective triangle which is fixedly connected with the upper protective cover, and the protective triangle is also arranged at the corresponding position on the lower protective cover.
The beneficial effects of this scheme lie in: the protection triangle plays a role in strengthening fixed connection and enhancing bearing force on the upper protection cover and the lower protection cover.
Further, one side of the protection triangle is tightly attached to the J-shaped tube.
The beneficial effects of this scheme lie in: the protective triangle may transfer a portion of the shear force to the vertical direction using the particular shape of the triangle.
Further, the positions of the through holes of the upper protective cover and the lower protective cover are in staggered fit with the positions of the reinforcing ribs of the flange connection ports.
The beneficial effects of this scheme lie in: the shearing force generated by the impact is born at the fixed connection positions at different positions, so that the bearing capacity of the device can be enhanced, and the integrity of the protected device can be better protected when the device is impacted.
Further, the upper protective cover and the lower protective cover are protective covers made of high-strength impact-resistant materials.
The beneficial effects of this scheme lie in: the flange connection part is protected through the upper protective cover and the lower protective cover, so that direct stress can be prevented, and the service life of the flange is prolonged.
