Description
Technical field
The invention belongs to the conveying machinery apparatus technology, relate to the structure of high-speed board chain hoisting machine, more particularly, the present invention relates to a kind of tail structure of high-speed board chain hoisting machine.
Background technology
NSE type high-speed board chain hoisting machine is widely used in the lifting of bigger powdery of operational throughput and little grainy material, as: thinner ore after cement, coal dust, the fragmentation.NSE plate chain type gig have following characteristics:
1, traffic capacity is big.This series gig is that gig, the lifting capacity of close cross sectional dimensions operational throughput maximum in the domestic gig is 100～1000m
3/ h.
2, expanded reach is wide.This class gig requires to lack to kind, the characteristic of material, not only can promote general granular material, and can promote the bigger material of chiseling property of mill.Require temperature of charge≤200 ℃.
3, driving power is little.Adopt inflow formula feeding, induction type discharging, high-capacity hopper, the intensive layout.When material promotes, almost do not have feed back and dig the material phenomenon, so reactive volt-amperes is few, save power about 30% than loop chain gig.
4, long service life.The feeding of gig is taked the inflow formula, need not to dig material, rare extruding and collision phenomenon between the material with bucket.Have slightly when when design, guaranteeing material and be scattered, reduced mechanical wear, adopt plate chain type high-strength abrasion-proof conveyer chain, prolonged the service life of conveyer chain and hopper greatly in feeding, gig discharging.Under the average service conditions, conveyer chain service life was above 3 years.
5, hoisting depth height, this gig operates steadily, and adopts plate chain type high-strength abrasion-proof conveyer chain, therefore can reach higher hoisting depth.Under specified operational throughput, hoisting depth≤50m.
6, good airproof performance, low in the pollution of the environment.
7, serviceability is good.Advanced principle of design and job operation have guaranteed the complete machine reliability of operation, and failure free time was above 20,000 hours.
8, operation, easy to maintenance, few easy workout part.
9, the rigidity of structure is good, the precision height.Casing after die mould welding, good rigidity, and outward appearance is beautiful.
10, integrated cost is low.Because energy efficient and maintenance are few, use cost is low.
The concrete structure of NSE plate chain type gig comprises: operation parts, actuating device, upper unit, middle part casing, lower device, lower device etc.Wherein:
The operation parts---form by hopper and bush roller chaiin;
Actuating device---form by driving platform, driving combination, messenger chain; Wherein, driving combination is made up of main gear reducer, fluid coupling, main motor, assisted deceleration motor, holdback; Combination of drive means is driving the flat-bed installation site, divides the left side dress and the right side to adorn two kinds:
Left side dress---in the face of inlet point, combination of drive means and messenger chain are in the left side of casing;
Right dress---in the face of inlet point, combination of drive means and messenger chain are on the right side of casing;
Upper unit---comprise upper housing, go up cover, go up parts such as axle assembling, holdback;
The middle part casing---be divided into segmentum intercalaris in the band support that connects with upper housing, be with and inspect segmentum intercalaris in segmentum intercalaris in the door, the standard (2.5m) and the high nonstandard middle segmentum intercalaris of 1m, 1.5m, make the lifting function be one grade and obtain different height with 0.5m;
Lower device---lower casing, inlet point, tailing axle assembling, tightening device (optional dress speed measuring device).
In the prior art, the tailing axle two ends of high-speed board chain hoisting machine afterbody connect uses biserial to be connected with slider shaft holder to the bulbus cordis globe bearing always, utilizes the slider shaft holder outside casing to finish tensioning.Because bearing seat is in the casing work outside, getting well again that the sealing arrangement of casing is done like this all can have a spot of gap, makes the material that is transported to overflow along the gap, and infiltrates bearing inside.The dust that infiltrates when bearing seat is inner increases along with the continuous increase of the period of service of machine, service life of bearing in the bearing seat that can significantly reduce like this, thus make applying unit need often to change tail bearing; And replacing each time all needs applying unit to stop production a period of time.Can bring the certain economic loss to applying unit so change bearing continually, and the excessive environment of giving of dust has also brought certain pollution.
Summary of the invention
Problem to be solved by this invention provides a kind of tail structure of high-speed board chain hoisting machine, its objective is to change gig afterbody supporting structure, prolongs its service life.
To achieve these goals, the technical scheme taked of the present invention is:
Tail structure of high-speed board chain hoisting machine provided by the present invention, comprise tailing axle, bearing seat, sprocket wheel, slide rail, slider support, weight box, described slide rail supports by slide rail and is connected with the casing of described high-speed board chain hoisting machine, described weight box is fixed on the described slide rail by bolt, nut and spring washer, and described tailing axle is installed on the described bearing seat by plain bearing.
The axle sleeve of described plain bearing for making by high-abrasive material.
Described bearing seat is installed in the casing inside of described high-speed board chain hoisting machine.
