Description
Technical field
The utility model relates to technical field of engineering machinery, especially a kind of to be used for container face crane steeraxle
Swinging structure.
Background technique
The front handling mobile crane steeraxle of container face crane steeraxle swinging structure requires rear-wheel to swing ± 3 °, such as schemes
Shown in 1, the swinging structure of mainstream is using intermediate shaft-penetrating type on pontic at present, and axis is parallel with vehicle front-rear direction, need to set
Meter is up to 1 meter or so of support shaft and corresponding cylindrical structure, rotary lubrication axle sleeve etc..Because support shaft weight is big, it is desirable that add
Work cylindricity, straightness are high, and cylinder needs both ends to process, and concentricity requires height, and total is complicated, cause processing cost height.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of front handling mobile crane steeraxle swinging structures, it can solve
The problem that existing front handling mobile crane steeraxle shaft-penetrating type swinging structure weight is big, structure is complicated, processing cost is high.
To solve the above-mentioned problems, the technical solution of the utility model is: this front handling mobile crane steeraxle swinging structure includes
There are frame support and pontic, the pontic includes the vertical plate that middle part is arranged and the upper plate connecting with the vertical plate two sides；It is described vertical
The both ends of plate are respectively provided with a left and right directions mounting hole, are equipped with oscillating bearing in the mounting hole, the oscillating bearing it is interior
Circle is equipped with support shaft, and the outer ring of the oscillating bearing is abutted with the mounting hole wall, outer ring end and the mounting hole
Inner hole step and end cap abut；The support shaft is connect with the frame support, in the inner ring and the vehicle of the oscillating bearing
The steel bushing of the relative position for fixing the oscillating bearing inner ring and frame support is provided between frame support.
More specifically scheme is: the oscillating bearing is self-lubricating knuckle bearing.
Further, the end cap is mounted on the pontic by bolt.
Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:
The utility model is smaller in view of swing angle, preceding using self-lubricating knuckle bearing as support and swinging structure
After arrange, the design of short axle simply supported beam, compared with prior art, rigidity is more preferable, simple and compact for structure, because support shaft shortens, cancels
Cylinder and lubricative axle sleeve on pontic, overall weight is lighter, and key part size is small, reduces difficulty of processing, and quality is easier to control,
Cost is lower.

Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is prior art front handling mobile crane steeraxle swinging structure schematic diagram, using intermediate shaft-penetrating type, axis on pontic
Line is parallel with vehicle front-rear direction, need to design up to 1 meter or so of support shaft and corresponding cylindrical structure, rotary lubrication axle sleeve
Deng because support shaft weight is big, it is desirable that processing cylindricity, straightness are high, and cylinder needs both ends to process, and concentricity requires height, and adds
Work is at high cost.
The front handling mobile crane steeraxle swinging structure of Fig. 2, Fig. 3, Fig. 4 and Fig. 5, including the vertical plate 11 at the middle part of pontic 1, on two pieces
Plate 12 and 11 butt welding of vertical plate are respectively provided with a left and right directions mounting hole, i.e. axis and vehicle front and back on 11 both ends of vertical plate
To vertical, for installing oscillating bearing 3, oscillating bearing 3 is self-lubricating knuckle bearing, and oscillating bearing 3 is installed on the right and left
Into mounting hole, the outer ring of oscillating bearing 3 is abutted with the mounting hole wall, the inner hole step of outer ring end and the mounting hole
And end cap 4 abuts, i.e. the outer ring radial direction of oscillating bearing is fixed by the mounting hole wall of vertical plate 11, and axial direction is by end cap 4
It is fixed with the inner hole step of the mounting hole of vertical plate 11；End cap 4 is mounted on pontic 1 by bolt 7；Self-lubricating knuckle bearing inner ring
Support shaft 2 is installed, support shaft 2 is connect with frame support 6, is provided with steel between self-lubricating knuckle bearing and frame support 6
Set 5, steel bushing 5 are used to fix the relative position of self-lubricating knuckle bearing Yu frame support 6.
Front handling mobile crane steeraxle requires rear-wheel to swing ± 3 °, and swing angle is smaller, therefore self-lubricating joint shaft can be used
It makes as support and swinging structure, front and back arrangement, the design of short axle simply supported beam, compared with prior art, rigidity is more preferable, and structure is simple
It is compact, because support shaft shortens, cancel cylinder and lubricative axle sleeve on pontic, overall weight is lighter, and key part size is small, reduces and adds
Work difficulty, quality are easier to control, and cost is lower.
