Description

Technical Field

[0002] In equipment such as metallurgy and rotary kilns, the roundness of the rotary kiln cylinder plays a crucial role in the overall operation of the equipment. The roundness of the cylinder is the basis of the coaxiality and straightness of the cylinder, and is a key index restricting the stable operation of the rotary kiln. Coaxiality refers to the degree of coincidence between the center line of the rotary kiln and the center line of its supporting device, and straightness refers to the deviation value between the center line of the rotary kiln and the center line of the transmission mechanism connecting it. Good coaxiality and straightness of the rotary kiln can make the heat energy utilization rate of the rotary kiln higher, the production efficiency higher, and at the same time, it is beneficial to reduce equipment loss, extend the equipment life, and improve the equipment performance. It is also the key to reducing equipment vibration and ensuring the stable operation of the equipment.

[0003] During the manufacturing process of the rotary kiln, technical means are used to ensure the roundness of a single-section cylinder, so as to improve the coaxiality and straightness of the rotary kiln cylinder and ensure the manufacturing precision of the equipment. The tools used in the current manufacturing process are less digital and less accurate, mainly relying on the experience of workers, and it is difficult to ensure the roundness during the cylinder manufacturing process.

The inner end of the connecting rod is connected to the mounting seat, and the outer end is threadedly connected to the adjustment screw rod.

The connecting rod extends into the installation groove and is fixedly connected to the connecting plate.

[0008] Preferably, the upper fixing plate and the lower fixing plate are symmetrically arranged up and down.

[0009] Preferably, a connection hole for connecting the adjustment screw rod is arranged on the outer end face of the connecting rod. A scale is connected to the adjustment screw rod, and an observation port for observing the scale is arranged in the middle of the connecting rod.

[0026] Furthermore, the mounting base 2 successively includes an upper fixing plate 21, a connecting plate 22, and a lower fixing plate 23 from top to bottom. The outer periphery of the connecting plate 22 is enclosed by the upper fixing plate 21 and the lower fixing plate 23 to form a mounting groove. The connecting rod 31 extends into the mounting groove and is fixedly connected to the connecting plate 22.
