Furthermore, the bearing ring and the jacking ring are connected with the inner wall of the cylinder body in a double-sided welding manner.

The connecting strength of the bearing ring, the jacking ring and the barrel is enhanced through double-side welding.

Furthermore, the outer wall of the barrel is provided with handles for fixing the barrel, and the handles are symmetrically distributed on the outer wall of the barrel.

The handle makes the outer sleeve easier to carry, easily operates in the work scene.

Further, the quantity of handle is two sets ofly, and every group is including being located same level and two handles that the symmetry set up on the barrel, and one of them group of two sets of handles is located barrel upper portion, and another group is located the barrel lower part to two sets of handles set up perpendicularly.

Advantageous effects

The jacking ring is arranged in the cylinder body, so that the outer diameter of the outer sleeve is reduced, the construction of binding the steel bars on the outer sleeve on site is more convenient, the structure is simple, and the production process is simple and convenient; and meanwhile, the reinforcing ribs are arranged between the bottom plate and the barrel, so that the structural strength of the bottom plate is greatly improved, and the safety factor of the outer sleeve is also greatly improved, thereby further ensuring the driving safety of the line.
