Supporting device for tire of rotary body

Abstract

The invention discloses a supporting device for a tire of a rotary body. The supporting device comprises a pair of first plates, a clamping part, a fixing frame, an air cooler, a control device and a processor. The lower surfaces of the first plates are fixed to the outer circumference of the rotary body, and a first gap is formed between the first plates. The clamping part comprises a second plate and clamping blocks. The clamping blocks are fixed to the second plate. The second plate is in lap joint on the first plates. The clamping blocks are clamped into the first gap. The fixing frame enables the tire to be pressed down so as to reduce the gap between the tire and the rotary body. The air cooler is arranged close to the rotary body and outputs cold air to surround the rotary body. The control device is used for controlling output of the air cooler. The control device comprises a temperature detector. The processor is used for controlling the air cooler to output the cold air when the temperature detector detects that the temperature of the rotary body rises. The supporting device is concise in structure and convenient to dismount, saves maintenance cost of equipment and prolongs the service life of the equipment.

Description

technical field [0001] The invention relates to a revolving body equipment, in particular to a revolving body wheel belt supporting device. Background technique [0002] Rotary equipment such as rotary kiln, rotary dryer and rotary cooler are often used in the building materials industry, chemical industry and metallurgical industry. In order to avoid the necking phenomenon of the cylinder when the cylinder is thermally expanded, the rotary equipment mostly adopts loose sleeve tires. That is, an appropriate gap should be reserved between the tire and the backing plate, but due to the relative sliding between the tire and the backing plate, the contact surface has a certain wear and tear. The longer the use time, the larger the gap and the faster the wear speed. The backing plate must be replaced after a certain period of time, and the gap between the tire and the cylinder is not suitable, and the cylinder is easily deformed. The existing backing plate structure usually adop...

[0002] Rotary equipment such as rotary kiln, rotary dryer and rotary cooler are often used in the building materials industry, chemical industry and metallurgical industry. In order to avoid the necking phenomenon of the cylinder when the cylinder is thermally expanded, the rotary equipment mostly adopts loose sleeve tires. That is, an appropriate gap should be reserved between the tire and the backing plate, but due to the relative sliding between the tire and the backing plate, the contact surface has a certain wear and tear. The longer the use time, the larger the gap and the faster the wear speed. The backing plate must be replaced after a certain period of time, and the gap between the tire and the cylinder is not suitable, and the cylinder is easy to deform

The existing backing plate structure usually adopts a fixed backing plate, and the backing plate is directly welded on the cylinder. When replacing the backing plate, the backing plate needs to be cut off one by one. When the cylinder is re-welded with a new backing plate, welding stress will be generated again, which will easily cause deformation of the cylinder

, Moreover, if the backing plate is slightly worn, the gap between the tire and the cylinder will change, which is not easy to control
