Background

The sliding bearing bush is the part of the sliding bearing contacted with the shaft, is very smooth and is in the shape of a bush-shaped semi-cylindrical surface. In the steelmaking process, when the dedusting fan rotor is replaced, adjusted and overhauled at every time, the fan sliding bearing bush needs to be scraped, so that the higher contact precision of the sliding bearing bush and the shaft neck of the fan rotor is ensured. The sliding bearing bush of the fan and the rotor journal are required to be ground and scraped for multiple times during replacement, adjustment and maintenance every time, and the sliding bearing bush is required to be taken and placed frequently during grinding until the sliding bearing bush and the rotor journal reach the required contact precision. In the prior art, when the sliding bearing bush of the fan is taken out and reinstalled, the whole crane for the fan rotor can be hoisted firstly, then the sliding bearing bush is taken out, the sliding bearing bush is reinstalled after scraping, and meanwhile, the fan rotor is put down, so that multiple operations are needed to achieve the contact precision.

Frequently hoisting the fan rotor is time-consuming and labor-consuming; too big damage that causes the sliding bearing bush when hoisting, whereabouts and the measurement of influence contact accuracy lead to maintenance efficiency lower, and then influence production efficiency.

SUMMERY OF THE UTILITY MODEL

Based on above technical problem, the utility model provides a fan sliding bearing shell dress gets support frame to it is lower to have solved among the prior art scheme to use the hoist frequently to hoist and put down fan rotor and lead to maintenance efficiency, and the range is too big when hoisting, whereabouts causes sliding bearing shell's damage and the problem that influences the contact accuracy.

The utility model provides a technical problem, adopt the utility model discloses technical scheme as follows:

a fan sliding bearing bush assembling and disassembling support frame mainly comprises a combination plate, a left bearing plate and a right bearing plate; the combination plate is positioned below the space between the left bearing plate and the right bearing plate, and the cross section of the combination plate is half of a regular hexagon divided along the center line; the left bearing plate and the right bearing plate are in the same horizontal plane and are symmetrical about the symmetry plane of the combination plate. Both bearing plates are provided with threaded through holes, and jacking bolts are arranged in the threaded through holes.

Preferably, the length of the inner side of the bonding plate is 75 mm. The length value is adopted to achieve the purpose of matching with the regular hexagon shaft end of the fan rotor.

Preferably, the bearing plate is 200mm long.

Preferably, the combination plate, the left bearing plate and the right bearing plate have a thickness of 16mm and a width of 100 mm. When the thickness is set to be larger, the hardness of the support frame is improved; the width is set to be large in order to increase the contact area with the end of the regular hexagonal shaft.

Preferably, the jacking bolts have a diameter of 20 mm.

Preferably, the combination plate, the left bearing plate and the right bearing plate are made of carbon steel.

Preferably, the combination plate and the bearing plate are fixed by welding.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model provides a support frame is got in fan sliding bearing shell dress has solved and has used the hoist to frequently hoist, put down the fan rotor so that take out many times or repack the sliding bearing shell after scraping, the too big damage that causes the sliding bearing shell of range and the problem that influences the contact accuracy when leading to the lower problem of maintenance efficiency and hoisting, whereabouts, improves the efficiency of overhauing.

Detailed Description

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Example 1

Please refer to fig. 3 and fig. 4. The utility model relates to a fan sliding bearing bush assembling and disassembling support frame, which mainly comprises a combination plate 7, a left bearing plate 6 and a right bearing plate 8; the combination plate 7 is positioned below the space between the left bearing plate 6 and the right bearing plate 8, the cross section of the combination plate is half of a regular hexagon, and the length of one side of the inner side of the combination plate is 75 mm; the left bearing plate 6 and the right bearing plate 8 are completely the same and are symmetrical in the same horizontal plane about the symmetry plane of the combination plate 7, and the length of the two bearing plates is 200 mm; threaded through holes are formed in the left and right bearing plates, and jacking bolts with the diameter of 20mm are arranged in the threaded through holes. The thickness of the whole support frame 3 is 16mm, and the width is 100 mm.
