This preferred scheme can also combine the actual dimensions specification of rod 7, adjusts the transfer passage size, when realizing carrying, avoids rod 7 to take place the skew.

Preferably, in the step b), the working temperature of the bearing on the driving mechanism is measured through the online temperature measuring mechanism 14, and when the working temperature is increased to 50 ℃, the cooling mechanism 2 is started to cool the roll shaft 5; when the working temperature is continuously increased to 60 ℃, the cooling water pressure of the cooling mechanism 2 is increased, and the cooling effect is increased; when the working temperature continues to rise to 70 ℃, the technician performs shutdown adjustment to ensure the safe working of the bearing. This preferred scheme can also be according to the operating temperature of real-time detection's bearing, adjusts the cooling effect to ensure bearing safety work, guarantee safe transport.

After the shutdown, the technician may use any adjustment measures to ensure safe operation of the bearing, such as replacing the bearing.

The specific values of the three temperature nodes in the above technical solution can be selected by those skilled in the art according to actual situations.

Preferably, in step b), when the roller body 6 is worn to be maintained, the replacement roller body 6 is removed. Change roll body 6, compare in current change roller 5, intensity of labour greatly reduced.

Preferably, in step b), a fixed baffle 12 and a movable baffle 13 are arranged in the middle of the roller shaft 5 to block high-temperature radiation from the heating furnace and the bar 7; and when the roller shaft 5 is worn and needs maintenance, the movable baffle 13 is opened, and the roller shaft 5 is replaced. Under this preferred scheme, the extension of the other end of roller 5 and cooling body 2 and fixed baffle 12 and adjustable fender 13 can cooperate each other, play and avoid high temperature radiation effect.

The present invention is illustrated in more detail below with reference to specific examples.

Example 1

The high temperature durable bar conveying roller of the present embodiment is structured as shown in fig. 1 and 2. The working process is as follows:

a) according to the influence of the position of the heating furnace and the temperature of the heating furnace on the roll shaft 5, the driving mechanism and the cooling mechanism 2, the extension length of the other end (namely the right end in the figure) of the roll shaft 5 is controlled, so that the roll shaft 5, the driving mechanism and the cooling mechanism 2 are far away from the billet on the roll body 6 outside the other end of the roll shaft 5, and high-temperature radiation is avoided.

b) The speed reduction motor 1 of the driving mechanism drives the roll shaft 5 to rotate, so that the roll body 6 connected with the roll shaft 5 in a key mode is driven to rotate, and the billet from the heating furnace is conveyed to the next process.

When the operating temperature of each part such as actuating mechanism is higher, open cooling body 2, the cooling water circulates according to the arrow direction that fig. 2 shows, specifically gets into inlet tube 24 through the water inlet of rotary joint 21, flows into the head department of the roller 5 other end, flows to rotary joint 21's delivery port through the space between roller 5 and the inlet tube 24 again, forms circulative cooling, has reduced the temperature of roller 5, roll body 6 and bearing, has prolonged its life greatly.

According to the high-temperature durable bar conveying roller, the roller shaft 5, the driving mechanism, the cooling mechanism 2 and the base 3 are arranged in an extending mode, and the cooling mechanism 2 is used for cooling, so that high-temperature radiation is effectively prevented, and the high-temperature durability of each part is improved; and the roller body 6 can be replaced in time, the replacement operation is convenient, and the maintenance cost is low.

Example 2

The high temperature durable bar conveying roller of the present embodiment is structured as shown in fig. 3 and 4. The working process is as follows:

a) according to the influence of the position of the heating furnace and the temperature of the heating furnace on the roll shaft 5, the driving mechanism and the cooling mechanism 2, the extension length of the other end (namely the right end in the figure) of the roll shaft 5 is controlled, so that the roll shaft 5, the driving mechanism and the cooling mechanism 2 are far away from the billet on the roll body 6 outside the other end of the roll shaft 5, and high-temperature radiation is avoided.

And according to the size specification of the billet, the horizontal distance between two stoppers 11 (shown in fig. 5, in an L-shaped ring structure) arranged in pairs is adjusted by adjusting the horizontal relative positions of a first kidney-shaped hole 1101 arranged on the stopper 11 and a second kidney-shaped hole arranged in the horizontal direction on the roller body 6.

And a fixed baffle 12 and a movable baffle 13 are arranged in the middle of the roll shaft 5 to block high-temperature radiation from the heating furnace and the bar 7.

b) The speed reduction motor 1 of the driving mechanism drives the roll shaft 5 to rotate, so that the roll body 6 connected with the roll shaft 5 in a key mode is driven to rotate, and the billet from the heating furnace is conveyed to the next process.

The working temperature of a bearing on the driving mechanism is measured through the online temperature measuring mechanism 14, and when the working temperature is increased to 50 ℃, the cooling mechanism 2 is started to cool the roll shaft 5; when the working temperature is continuously increased to 60 ℃, the cooling water pressure of the cooling mechanism 2 is increased, and the cooling effect is increased; when the working temperature is continuously increased to 70 ℃, the technician stops the machine and replaces the bearing to ensure the safe working of the bearing.

When the cooling mechanism 2 is started, cooling water circulates in the direction of an arrow shown in fig. 2, specifically enters the water inlet pipe 24 through the water inlet of the rotary joint 21, flows into the head part at the other end of the roller shaft 5, and then flows to the water outlet of the rotary joint 21 through the gap between the roller shaft 5 and the water inlet pipe 24, so that circulating cooling is formed, the temperature of the roller shaft 5, the temperature of the roller body 6 and the temperature of the bearing are reduced, and the service life of the roller body is greatly prolonged.

When the roller body 6 is worn and needs to be replaced or maintained, the baffle 8 connected to the other end of the roller shaft 5 through the bolt and the flat key 10 connecting the roller body 6 and the roller shaft 5 are detached, the roller body 6 is taken down from the roller shaft 5, and the roller body 6 is replaced or maintained.

When the roller shaft 5 is worn and needs maintenance, the movable baffle 13 is opened, and the roller shaft 5 is replaced.

According to the high-temperature durable bar conveying roller, the roller shaft 5, the driving mechanism, the cooling mechanism 2 and the base 3 are arranged in an extending mode, the real-time temperature measurement of the online temperature measuring mechanism 14 is matched to adjust the cooling of the cooling mechanism 2, and the arrangement of the fixed baffle 12 and the movable baffle 13 is matched, so that the high-temperature radiation is efficiently prevented in a synergistic mode, and the high-temperature durability of each part is improved; and the roller body 6 can be replaced in time, the replacement operation is convenient, and the maintenance cost is low.

This embodiment can also adapt to the steel of multiple specification, guarantees steel safe transport, can also combine the behavior, in time adjusts the cooling effect, is practicing thrift under the condition of cooling cost, makes the cooling effect best.
