Abstract
The utility model relates to a supporting structure for bucket teeth of a log grab bucket. The supporting structure comprises two symmetric bucket teeth, and is characterized by comprising a central shaft inserted on the bucket teeth and used for connecting the bucket teeth, wherein a positioning sleeve used for limiting the axial displacement of the central shaft is fixed on the central shaft; an outer sleeve, which is a seamless steel pipe, is sleeved on the central shaft; clearances are formed between the central shaft and the bucket teeth; and a clearance is formed between the outer sleeve and the central shaft. Through the adoption of the supporting structure, the strength and the deformation-resistant capability of the bucket teeth are guaranteed, and the grabbing stress of the grab bucket can be released due to the clearances between the central shaft and the bucket teeth. Therefore, the central shaft and the bucket teeth can be prevented from deforming effectively; and the service life and the maintenance period of the grab bucket are prolonged.
Description
Technical field
The utility model belongs to the handling tool technical field, particularly relates to a kind of supporting construction that is used to load and unload the grab bucket bucket chi of log.
Background technology
Log is former the long juggle that is cut into certain-length to standard code or special stipulation by size, shape, quality, is one of Very Important Cargo of harbour handling.In the prior art, the harbour is carried out ship-discharging operation through following method to log:
On the door machine, connect the special-purpose grab bucket of log, utilize the log of grabbing bucket to grasp deliver from vault the boats and ships carrying.Above-mentioned grab bucket tool is a plurality of to have bucket tooth, connects strut bar between the symmetrical bucket tooth, and the two ends of strut bar are welded on two bucket tooths; Strut bar can effectively increase the bulk strength and the non-deformability of grab bucket, and still, grab bucket is in the long-term use process; The welding end of strut bar and bucket tooth is usually grasped stress influence and is out of shape, snaps and rupture, and the service life of whole bucket tooth is short, and maintenance intervals is short; Service expenditure is high, and influences the handling efficiency of goods.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, installation and processing easily, can increase the intensity and the non-deformability of grab bucket; And can prolong the service life and the maintenance intervals of grab bucket, thereby improve the supporting construction of the log grab bucket bucket tooth of handling efficiency.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of supporting construction of log grab bucket bucket tooth; Two bucket tooths that comprise symmetry; It is characterized in that: comprise the center shaft that is used to connect two bucket tooths that is inserted on two bucket tooths; Be fixed for limiting the locating bush of center shaft longitudinal travel on the said center shaft, be set with overcoat on the said center shaft, said overcoat is a solid drawn pipe; Be provided with the gap between said center shaft and the bucket tooth, be provided with the gap between said overcoat and the center shaft.
The utility model can also adopt following technical scheme:
Weld locating bush on the two ends of center shaft.
Advantage and the good effect that the utlity model has are: connect through center shaft between two bucket tooths in the utility model; Be provided with the gap between center shaft and the bucket tooth; Center shaft carries out axial location by locating bush; So make center shaft both guarantee the intensity and the non-deformability of bucket tooth, can let out power to the extracting stress of grab bucket through the gap that is provided with between center shaft and the bucket tooth again, can effectively avoid the distortion of center shaft and bucket tooth.Gap suit overcoat on center shaft has further increased the intensity and the non-deformability of center shaft, thereby prolongs the service life and the maintenance intervals of grab bucket.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: 1, bucket tooth; 2, center shaft; 3, locating bush; 4, overcoat.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2, a kind of supporting construction of log grab bucket bucket tooth.Two bucket tooths 1 that comprise symmetry; Be connected with center shaft 2 between two bucket tooths 1, center shaft 2 is to form with the round steel cutting, and the two ends of center shaft 2 are inserted on two bucket tooths 1; Be fixed for limiting the locating bush 3 of center shaft longitudinal travel on the center shaft 2; In the present embodiment, the two ends of center shaft 2 are inserted on two bucket tooths 1 and connect two bucket tooths 1, and center shaft 2 connects out the two ends of bucket tooth 1 and all welds locating bush 3.Be provided with the gap between center shaft 2 and the bucket tooth 1, under the prerequisite of intensity that has guaranteed bucket tooth and non-deformability, can let out power to the extracting stress of grab bucket, can effectively avoid center shaft 2 and bucket tooth 1 distortion through the gap that is provided with between center shaft 2 and the bucket tooth 1.On the center shaft 2 between two bucket tooths 1 suit overcoat 4, overcoat 4 is a solid drawn pipe.Be provided with the gap between overcoat 4 and the center shaft 2, further increased the intensity and the non-deformability of center shaft, thereby prolong the service life and the maintenance intervals of grab bucket.
Claims (2)
1. the supporting construction of log grab bucket bucket tooth; Comprise two bucket tooths of symmetry, it is characterized in that: comprise the center shaft that is used to connect two bucket tooths that is inserted on two bucket tooths, be fixed for limiting the locating bush of center shaft longitudinal travel on the said center shaft; Be set with overcoat on the said center shaft; Said overcoat is a solid drawn pipe, is provided with the gap between said center shaft and the bucket tooth, is provided with the gap between said overcoat and the center shaft.
