Abstract
The utility model discloses heavy load cylinder, including cylinder, drum shaft, cylinder former, described cylinder former is arranged at two ends in described cylinder, described drum shaft is disposed through the center of described cylinder, also include expansion sleeve, described expansion sleeve is sheathed on described drum shaft, and between described drum shaft and described cylinder former, relies on bolt tensioner thereon to connect described drum shaft and described cylinder former.The utility model has the advantages that former and the axle using the mode of tensioner connection to connect cylinder, the pressure produced between female surface and frictional force is relied on to realize load transmission, have that centering precision is high, transmission torque is big, reliable clamping, the feature that is convenient to mount and dismount, is easily changed, the problem solving existing technique axle easy fracture, ensure the work efficiency of tramp iron separator, drastically increase its service life.
Description
Technical field
This utility model relates to the fields such as heavy-duty machinery, wind-fire power generator tool, printing machinery, is specifically related to a kind of large-scale
Belt tramp iron separator.
Background technology
Large belt tramp iron separator, the effect in electric power plant coal transportation operation is most important.Heavy load cylinder is mainly used in
Large belt tramp iron separator, is one of its critical piece.The quality of heavy load cylinder determines the work of large belt tramp iron separator
Quality, service life, maintenance cost etc..And, along with country reduces discharging the enforcement of policy, each high-power station carries out structural adjustment, adopts
Having taken the measure of " upper big pressure is little ", the quality of heavy load cylinder is also had higher requirement by this.
Existing heavy load cylinder, uses the technique welded to connect as one between former with axle.Although welding procedure
Being connected firmly, but after load cylinder operates for a long time, add and affected by gravity, the axle easy fracture of cylinder, weld is the easiest
Cracking.This will affect the normal work of tramp iron separator, reduces work efficiency, adds production cost.
Utility model content
Utility model purpose: for the problems referred to above, the purpose of this utility model is to provide one and is applicable to top load occasion,
And simple in construction, reliable load cylinder.
Technical scheme: heavy load cylinder, including cylinder, drum shaft, cylinder former, described cylinder former is arranged at described
Two ends in cylinder, described drum shaft is disposed through the center of described cylinder, also includes that expansion sleeve, described expansion sleeve are sheathed on institute
State on drum shaft, and between described drum shaft and described cylinder former, rely on bolt tensioner thereon to connect described cylinder
Axle and described cylinder former.
Further, a length of H of cylinder, a length of h, H:h=1:1.10 of drum shaft～1.20, to keep optimal
Stability.
Further, bolt used is high-strength bolt, its strength grade >=8.8 grade, to ensure to provide enough
Pressure and frictional force.
Beneficial effect: compared with prior art, the utility model has the advantages that the mode using tensioner connection connects cylinder
Former and axle, rely on the pressure produced between female surface and frictional force to realize load transmission, have that centering precision is high, transmission torque
Greatly, reliable clamping, the feature that is convenient to mount and dismount, is easily changed, the problem solving existing technique axle easy fracture, ensured tramp iron separator
Work efficiency, drastically increase its service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is partial structurtes enlarged diagram at A in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, it should be understood that these embodiments are only used for
This utility model is described rather than limits scope of the present utility model, after having read this utility model, art technology
Personnel all fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
As it is shown in figure 1, a kind of heavy load cylinder, including cylinder 1, drum shaft 2, cylinder former 3, and expansion sleeve 4.Rolling
Cylinder former 3 is installed on the inside of cylinder 1 and from cylinder 1 both sides 10mm, the diameter compatible of its external diameter and cylinder 1 so that its outer wall
It is close to the inwall of cylinder 1.Drum shaft 2 extends transversely through in the center of cylinder 1, a length of H of cylinder 1, drum shaft 2 a length of
H, H:h=1:1.10～1.20, stability optimal during to remain on.
As in figure 2 it is shown, expansion sleeve 4 is sheathed on drum shaft 2, and between drum shaft 2 and cylinder former 3, by twisting
Tight high-strength bolt thereon 5 comes tensioner connection drum shaft 2 and cylinder former 3.The intensity palpus of bolt 5 >=more than 8.8 grades so that
Enough pressure and frictional force can be produced, it is achieved load transmission between female surface.This utility model simple in construction, reliable, it is suitable for
In top load, alternate torque occasion frequently and easy to maintenance, drastically increase the service life of tramp iron separator, be effectively ensured
Work efficiency.
