Detailed Implementation

[0018] Please see Figures 3-5This embodiment is an auxiliary support device for hoisting a mill cylinder, including several support brackets 200 and several sets of fixed supports 300. Each support bracket 200 has an arc-shaped groove at its top and a jack 100 at its bottom. Each set of fixed supports 300 consists of two symmetrically arranged supports, each including a base plate 301, a vertical support plate 302, a top plate 303, and an adjusting plate 305. The base plate 301, vertical support plate 302, and top plate 303 are welded and fixed. The adjusting plate 305 is located on the top plate 301. Above 03, a pin 306 is installed between the adjusting plate 305 and the top plate 303 to make the adjusting plate 305 and the top plate 303 rotatably connected. On the top plate 303, a set of adjusting screws 304 are installed on each side of the pin 306. The adjusting screws 304 are threadedly connected to the top plate 303. The angle between the adjusting plate 305 and the top plate 303 is controlled by the top of the adjusting screws 304 contacting the bottom surface of the adjusting plate 305. The adjusting plate 305 is provided with a connection hole that matches the outer wall surface of the cylinder. The bottom plate 301 is provided with anchor bolt holes.

[0019] Preferably, a support block is provided on each side of the center of the top surface of the top plate 303, and the pin 306 is installed between the two support blocks. The bottom surface of the adjusting plate 305 is provided with two protrusions corresponding to the pin 306. The protrusions are fixedly connected to the adjusting plate 305 and slidably connected to the pin 306.

[0020] Preferably, the top plate 303 and the bottom plate 301 are provided with an included angle of 10°-30°.

[0021] Preferably, the support base 200 includes a base plate 201, a vertical support plate 202 is mounted on the top of the base plate 201, a plurality of stiffening plates 203 are mounted on both sides of the vertical support plate 202, and an arc-shaped support plate 204 is mounted on the top of the vertical support plate 202 and the stiffening plates 203.

[0022] The construction process using this utility model is as follows: Figure 1 , Figure 2As shown, firstly, several support brackets 200 and corresponding jacks 100 are placed in the set positions. The support height of each support bracket 200 is adjusted by the jacks 100. Then, the lower half of the cylinder is lifted above the support brackets 200 by a crane, without being unhooked. Then, workers install fixed brackets 300 at multiple locations on both sides of the cylinder. First, the adjusting plate 305 is connected and tightened to the reserved installation holes on the outer wall of the cylinder with bolts. Then, the angle of the adjusting plate 305 is adjusted according to the diameter of the cylinder and the curvature of the outer wall. The tilt angle of the adjusting plate 305 is controlled by adjusting the extension length of each adjusting screw 304, so that the base plate 301 is parallel to the ground, thereby ensuring that the anchor bolts can be installed normally on the base plate 301. After all the fixed brackets 300 are installed, the crane releases the hook and places the cylinder on the support brackets 200. At this time, the cylinder will not slide due to the change of center of gravity when the upper two halves of the cylinder are installed because the two sides are pulled by the fixed brackets 300.

[0023] Depending on the diameter of the cylinder, the adjustment plate 305 of the fixed bracket of this utility model can be adjusted at an appropriate angle to adapt to different cylinder diameters. Therefore, this utility model can be applied to the installation of cylinders with different diameters and has strong adaptability.
