The annular water-absorbing layer 5 is composed of a water-absorbing resin, and the annular wear-resistant layer 4 is made of alloy metal. The annular water-absorbing layer 5 can conflict with the inner arc surface of the annular wear-resistant layer 4. The roller cover body 1 is composed of a high-toughness polymer material.

[0027] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0028] In actual application, the installation steps are similar to the traditional method; due to the use environment, the annular water-absorbing layer 5 can absorb the existing water vapor, thereby preventing the corrosion of the roller sleeve after the water vapor accumulates. Subsequently, in a high-temperature environment, since the annular water-absorbing layer 5 is in direct contact with the annular wear-resistant layer 4, the annular wear-resistant layer 4 can be cooled by the water in the water-absorbing layer, thereby reducing the corrosion of the surface of the annular wear-resistant layer 4 by the high temperature; at the same time, the support rod 10 provided can prevent the roller sleeve body 1 from generating a concentrated force acting on the rotating shaft 9, thereby preventing the rotating shaft 9 from bending or even breaking, thereby extending the service life of the device.

Since the annular water-absorbing layer 5 expands due to water absorption, it will come into contact with the annular wear-resistant layer 4. In a high temperature environment, the water vapor in the annular water-absorbing layer 5 can cool the annular wear-resistant layer 4, thereby preventing the surface coating of the wear-resistant layer from failing due to heat; by setting the bearing, the bending force of the roller sleeve body 1 on the rotating shaft 9 can be reduced, thereby extending the service life of the rotating shaft 9; and the turning handle and the turning hole 12 set at the same time can freely choose between manual and electric operation when collecting the guide cable.
