Abstract
Provided is a grab bucket. The grab bucket is composed of a central shaft 1, a locating sleeve 2, a knuckle bearing 3, bucket body connection sleeves 4, a lower pulley base seat 5, a locating nut 6 and an end cover plate 7. The central shaft 1 penetrates through two bucket body connection sleeves 4 of the end cover plate 7 sequentially through a center hole of the lower pulley base seat 5 of the grab bucket, the central shaft 1 is sequentially provided with the knuckle bearing 3, the locating sleeve 2 and the locating nut 6, and the knuckle bearing 3 is matched with the bucket body connection sleeves 4. A main damaged part of the grab bucket is the knuckle bearing, and users just need to dismantle the locating nut to replace the knuckle bearing; and service life of the knuckle bearing can be 1-2 years so that the central shaft and a bucket body can not be affected by abrasion of the knuckle bearing.
Description
Technical field
The utility model belongs to engineering machinery, is a kind of grab bucket of unloading bulk cargo that is used to grab.
Background technology
Its bucket body middle and lower part rotation assembly of existing bulk cargo grab bucket generally is made up of baffle plate, central axis, non-tender anti-wear sleeve, bucket body adapter sleeve, and the lower sheave pedestal is contained in the central axis middle part.The component wear deterioration is serious in the use, and its wearing and tearing deterioration is characterized as: anti-wear sleeve is wearing and tearing earlier, and then central axis wearing and tearing, back bucket body adapter sleeve wearing and tearing; Grab bucket is often paralysed because of the central axis wear out failure, is generally application life 3～6 months, and the big maintenance cost of its follow-up maintenance load is high simultaneously.
The utility model content
The utility model aims to provide a kind of novel grab bucket that overcomes above-mentioned prior art weak point; The rotation assembly adopts standard component (oscillating bearing) to substitute the novel assembling form of anti-wear sleeve; Can reduce the probability that grab bucket is paralysed because of the central axis wear out failure at double; Novel grab bucket can be brought up to 1～2 year application life, reduces maintenance load and maintenance cost simultaneously at double.
The technical scheme of utility model: grab bucket, form by central axis, positioning sleeve, oscillating bearing, bucket body adapter sleeve, lower sheave pedestal, setscrew nut and end casing.Central axis passes two bucket body adapter sleeves of band edge cover plate successively through the centre bore of grab bucket lower sheave pedestal, is equipped with oscillating bearing, positioning sleeve, setscrew nut on the central axis successively; Oscillating bearing cooperates with bucket body adapter sleeve.
Its assembling use characteristic is: the inside and outside circle of oscillating bearing is fitted in respectively on central axis, the bucket body junction inner ring, and through central axis end, positioning sleeve, setscrew nut location; In grab bucket bucket body moving process, central axis and oscillating bearing inner ring are whole to keep motionless, and bucket body adapter sleeve and oscillating bearing outer ring are whole around the rotation of oscillating bearing inner ring.
The advantage of utility model: the oscillating bearing in the rotation assembly adopts standard component to substitute the novel assembling form of anti-wear sleeve; Can reduce the probability that grab bucket is paralysed because of the central axis wear out failure at double; And main damaged part is an oscillating bearing, removes the setscrew nut replacing and gets final product; Novel grab bucket can be brought up to 1～2 year application life, reduces maintenance load and maintenance cost simultaneously at double.

Among the figure: 1-central axis, 2-positioning sleeve, 3-oscillating bearing, 4-bucket body adapter sleeve, 5-lower sheave pedestal, 6-setscrew nut, 7-end casing, 8-location-plate, 9-anti-wear sleeve.
The specific embodiment
Below in conjunction with accompanying drawing, contrast prior art, further specify the content of utility model with embodiment.
Like Fig. 1, shown in Figure 2, the utility model grab bucket is made up of central axis 1, positioning sleeve 2, oscillating bearing 3, bucket body adapter sleeve 4, lower sheave pedestal 5, setscrew nut 6 and end casing 7.Central axis 1 passes two bucket body adapter sleeves 4 of band edge cover plate 7 successively through the centre bore of grab bucket lower sheave pedestal 5, is equipped with oscillating bearing 3, positioning sleeve 2, setscrew nut 6 on the central axis 1 successively; Oscillating bearing 3 cooperates with bucket body adapter sleeve 4.
Its assembling use characteristic of utility model is: the inside and outside circle of oscillating bearing 3 is fitted in respectively on the inner ring of central axis 1, bucket body adapter sleeve 4, and locatees through end, positioning sleeve 2, the setscrew nut 6 of central axis 1; In grab bucket bucket body moving process, central axis 1 keeps motionless with the inner ring of oscillating bearing 3 is whole, bucket body adapter sleeve 4 and the whole inner ring rotation around oscillating bearing 3 in the outer ring of oscillating bearing 3.
Shown in Fig. 3 books, the prior art grab bucket is made up of central axis 1, bucket body adapter sleeve 4, lower sheave pedestal 5, setscrew nut 6 and end casing 7, location-plate 8 and anti-wear sleeve 9.
The utility model grab bucket is in experiment operation on the grain slag crane of the high auxilliary workshop of iron-smelter in 2011, and is respond well.
