Description

A demolish frock for axial-flow type coal adds quick-witted impeller

Technical Field

The utility model relates to a demolish frock that is used for axial-flow type coal to add quick-witted impeller.

Background

Generally, the matching size of the impeller and the shaft is micro interference, and the matching of the thin-wall riveted impeller and the shaft in the axial-flow type coal processing machine is also adopted. Typically, the mating impeller is removed by heating. Because the impeller base plate is thicker and the wall thickness of the blade is thinner in the axial-flow type coal processing machine, when the impeller is dismantled, if the micro interference magnitude is larger or burrs exist, the impeller can be dismantled from the shaft only by increasing the heating temperature. The excessive heating temperature can lead the thin-wall blade of the impeller to be irregularly deformed, so that the unbalance of the rotor assembly after dynamic balance correction is randomly changed, the dynamic balance correction is invalid, the operation vibration of the fan is increased after the assembly, and the normal and reliable operation of the axial-flow coal processing machine is influenced.

Disclosure of Invention

The utility model aims to solve the technical problem that a demolish frock for axial-flow type coal adds quick-witted impeller is provided, the defect that traditional impeller demolishs is overcome to this frock, can demolish the impeller fast, high-efficient, safety, avoids the dynamic balance correction inefficacy that leads to because of impeller heating deformation, and improve equipment maintenance efficiency and quality ensure normal, the reliable operation of axial-flow type coal adds quick-witted.

For solving the technical problem, the utility model is used for axial-flow type coal adds quick-witted impeller demolish frock includes ha fu sleeve, four holding screw, two wire rope and back chain, ha fu sleeve is through twisting the bolt-up in ha fu sleeve both sides otic placode, ha fu sleeve circumference interval is equipped with four screws, four holding screw twist in four screws, the otic placode of ha fu sleeve both sides is seted up the through-hole, two wire rope's one end is located the through-hole of ha fu sleeve both sides otic placode, the other end are connected the back chain, the axle tip of axial-flow type coal with quick-witted impeller is located to the back chain.

Further, four screw holes on the circumference of the half sleeve are arranged at an angle of 90 degrees and are deviated from the central axis by 45 degrees.

Furthermore, one ends of the two steel wire ropes are arranged in through holes of ear plates on two sides of the half sleeve through shackles.

Because the utility model is used for axial-flow type coal adds quick-witted impeller demolish frock has adopted above-mentioned technical scheme, this frock is including hasping the husband sleeve promptly, four holding screw, two wire rope and back chain, hasping the husband sleeve through twisting in the bolt-up of hasping husband sleeve both sides otic placode, hasping husband sleeve circumference interval and being equipped with four screws, four holding screw are twisted in four screws, the otic placode of hasping husband sleeve both sides is seted up the through-hole, the back chain is connected to the through-hole of hasping husband sleeve both sides otic placode is located to two wire rope's one end, the shaft tip of axial-flow type coal adds quick-witted. The fixture overcomes the defect of the traditional impeller removal, can rapidly, efficiently and safely remove the impeller, avoids the failure of dynamic balance correction caused by the heating deformation of the impeller, improves the maintenance efficiency and quality of equipment, and ensures the normal and reliable operation of the axial-flow coal feeder.

Drawings

The invention will be described in further detail with reference to the following drawings and embodiments:

FIG. 1 is a schematic view of the connection between a half sleeve and a set screw in the demolition tool;

FIG. 2 is a top view of FIG. 1;

fig. 3 is an application schematic diagram of the demolition tool.

Detailed Description

Embodiment is shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a demolish frock for axial-flow type coal adds quick-witted impeller includes ha fu sleeve 1, four holding screw 2, two wire rope 3 and back-up chain 4, ha fu sleeve 1 is through screwing in the bolt-up of 1 both sides otic placode of

ha fu sleeve

11, 1 circumference interval of ha fu sleeve is equipped with four screws 13, four holding screw 2 screw in four screws 13, the otic placode 11 of 1 both sides of ha fu sleeve sets up through-hole 12, the other end of 11 otic placodes of 1 both sides of ha fu sleeve are connected back-up chain 4, the 5 tip of shaft of axial-flow type coal adds quick-witted impeller are located to back-up chain 4.

Preferably, four screw holes 13 on the circumference of the half sleeve 1 are arranged at an angle of 90 degrees and are deviated from the central axis by 45 degrees.

Preferably, one end of each of the two steel wire ropes 3 is arranged in a through hole 12 of an ear plate 11 at two sides of the huff sleeve 1 through shackle.

As shown in fig. 3, when the impeller of the axial-flow coal adding machine is removed, firstly, the half sleeve 1 is hooped on the base disc of the impeller 6 and is fastened by bolts, then four fastening screws 2 are screwed on four screw holes 13 on the circumference of the half sleeve 1 and are locked with the base disc of the impeller 6, so that the half sleeve 1 is fixed on the base disc of the impeller 6, one ends of two steel wire ropes 3 are connected with lug plates 11 on two sides of the half sleeve 1 by shackles, the other ends of the steel wire ropes 3 are respectively hung on a chain block 4, the chain block 4 is arranged at the end part of the wheel shaft 5, and the impeller 6 can be easily removed from the wheel shaft 5 by slightly pulling the chain block 4 and slightly heating the base disc of the impeller 5.

After the tool is applied, the multi-section impeller of the axial-flow coal feeding machine is dismantled, so that the dynamic balance correction failure and the influence on the installation quality of a fan due to the deformation of the heating impeller can be greatly avoided, the equipment maintenance efficiency and quality are improved, the technical assembly requirement is met, and the normal and reliable operation of the axial-flow coal feeding machine is ensured.
