Description

Technical Field

[0001] This utility model relates to the field of mill installation technology, specifically to a mill cylinder alignment auxiliary device. Background Technology

[0002] Mills are large pieces of equipment commonly used in industrial production. They mainly consist of a rotating drum. The rotating drum of a large mill is generally composed of multiple connected drum bodies. Flanges are installed between adjacent drum bodies, and the flanges are connected by bolts. In actual installation and construction, due to the large weight and size of the drum bodies, if there are differences in the alignment of the bolt holes between the drum bodies, the position of the drum bodies needs to be adjusted. Otherwise, the bolt holes of the two drum bodies cannot be tightened by bolts. In actual construction, multiple workers are required to cooperate with a crane to operate the mill, which is very difficult and inefficient. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art and to provide a mill cylinder alignment auxiliary device.

[0004] This utility model provides the following technical solution: a mill cylinder alignment auxiliary device, including an L-shaped support plate, the L-shaped support plate having a long side and a short side, a positioning shaft being provided on the side of the long side facing the short side, the diameter of the positioning shaft being smaller than the bolt hole diameter of the cylinder flange, the length of the positioning shaft being smaller than the thickness of the cylinder flange, a support plate being provided on the side of the short side facing the long side, the support plate being perpendicular to the L-shaped support plate, and the support plate being used to install a jack.

[0005] Preferably, the diameter of the positioning shaft is greater than the thickness of the L-shaped support plate.

[0006] Preferably, the thickness of the L-shaped support plate is 25-30mm, and the diameter of the positioning shaft is 30-40mm.

[0007] Preferably, the length of the long side is 650-800mm and the width is 150-300mm, and the length of the short side is 450-550mm and the width is 150-300mm.

[0008] Compared with the prior art, the advantages of this utility model are: it is simple to manufacture, convenient and quick to use, can effectively improve the installation efficiency of mill cylinder bolts, can be applied to auxiliary alignment operations at multiple angles of the cylinder, and has strong applicability.

[0014] Please see Figure 1-2 This embodiment is a mill cylinder alignment auxiliary device, including an L-shaped support plate. The L-shaped support plate has a long side 1 and a short side 2. A positioning shaft 3 is provided on the side of the long side 1 facing the short side 2. The diameter of the positioning shaft 3 is smaller than the diameter of the bolt hole of the cylinder flange, and the length of the positioning shaft 3 is smaller than the thickness of the cylinder flange. A support plate 4 is provided on the side of the short side 2 facing the long side 1. The support plate 4 is perpendicular to the L-shaped support plate and is used to install a jack 5.

[0015] Preferably, the diameter of the positioning shaft 3 is greater than the thickness of the L-shaped support plate. Preferably, the thickness of the L-shaped support plate is 25-30mm, and the diameter of the positioning shaft 3 is 30-40mm.

[0016] Preferably, the length of the long side 1 is 650-800mm and the width is 150-300mm, and the length of the short side 2 is 450-550mm and the width is 150-300mm.

[0017] like Figure 3 , Figure 4 As shown, the operation of this utility model is as follows: First, insert the positioning shaft 3 of the L-shaped support plate into the bolt hole of the flange of a cylinder A6, so that the support plate 4 is aligned with the flange of the cylinder B7. Install the jack 5 between the flange of the cylinder B7 and the support plate 4, and then operate the jack 5 to slowly push. Observe the bolt hole where the positioning shaft 3 is located from the outside. When the bolt holes of the flanges of cylinder A6 and cylinder B7 are aligned, the jack 5 stops moving. Finally, insert the connecting bolt from the bolt hole of the flange of cylinder B7, remove the jack 5 and the L-shaped support plate, and tighten the connecting bolt.
