Abstract
The utility model provides a nylon sliding block for a polygonal telescopic arm. The nylon sliding block comprises a nylon sliding block body, wherein the transverse section of the nylon sliding block body is circular-arc-shaped or broken-line-shaped; the longitudinal section of the nylon sliding block body is L-shaped; the nylon sliding block body is fixed on the telescopic arm by virtue of the L-shaped bottom; a groove with a self-lubricating function is formed in the upper surface of the nylon sliding block body; a chamfer facilitating installation is arranged at the end of the nylon sliding block body. The nylon sliding block for the polygonal telescopic arm has the advantages and positive effects that the contact area of the nylon sliding block and the polygonal telescopic arm is increased, stress concentration during stress is reduced, and the strength of the polygonal telescopic arm is improved; the rigidity of the polygonal telescopic arm can be effectively improved, and the deformation is reduced; the groove is designed to have the self-lubricating function; by virtue of the design of the chamfer, installation and replacement are facilitated, and the polygonal telescopic arm nylon sliding block can be operated manually.
Description
Technical field
The utility model belongs to technical field of engineering machinery, especially relates to a kind of polygon telescopic boom nylon slide block.
Background technology
Between each joint arm of box type telescopic boom hoisting crane, need to arrange nylon slide block, in order to support and to keep the relative sliding between each joint telescopic boom.
In existing technology, general polygon telescopic boom respectively saves the front lower slider designs quadrate structure between arm, and the area of contact between the slide block of this square structure and each joint arm is very little, thereby causes telescopic boom and slide block contact site stress concentration phenomenon.On the other hand, in order to strengthen area of contact, reduce the radius bend of polygon telescopic boom, but reduced the rigidity of telescopic boom, the downwarp amount of polygon telescopic boom is increased.
Summary of the invention
In order to overcome the problems referred to above, technical problem to be solved in the utility model is to provide one can obviously increase telescopic boom and slide block area of contact, improves the polygon telescopic boom nylon slide block of polygon telescopic boom rigidity.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of polygon telescopic boom nylon slide block, comprises nylon slide block body, and the horizontal section of described nylon slide block body is circular arc or fold-line-shaped.
Further, the longitudinal profile of described nylon slide block body is L shaped, by L shaped bottom, is fixed on telescopic boom.
Further, the upper surface of described nylon slide block body has been provided with the groove of self-lubricating function.
Further, the end of described nylon slide block body is provided with the convenient chamfering by filling.
Further, described nylon slide block body is by slide block baffle plate, slide block backing plate and be bolted on telescopic boom.
Advantage and the good effect that the utlity model has are:
Increase and the area of contact of polygon telescopic boom, reduce stress when stressed and concentrate, improved the intensity of polygon telescopic boom;
Energy actv. improves the rigidity of polygon telescopic boom, reduces its distortion;
Trench design has self-lubricating function;
Chamfer design makes to install to be changed conveniently, manual operation;
Lamps structure is simple, and tooling cost is low.

The specific embodiment
As shown in Figures 1 to 4, a kind of polygon telescopic boom nylon slide block of the present utility model, comprises nylon slide block body 1, and the horizontal section of described nylon slide block body 1 can be circular arc or fold-line-shaped, and preferred circular arc, increases the area of contact with telescopic boom 2 here; The longitudinal profile of described nylon slide block body 1 is L shaped, by L shaped bottom, is fixed on telescopic boom 2, and L shaped bottom and telescopic boom 2 contacts side surfaces, and fixing by slide block baffle plate 4, slide block backing plate 5 and bolt 6; The upper surface of described nylon slide block body 1 has been provided with the groove 3 of the intersection of self-lubricating function; The end of described nylon slide block body 1 is provided with convenient by the chamfering of dress.
The working process of this example: as shown in Figure 4, multiple nylon slide block bodies 1 are placed on telescopic boom 2, the L shaped bottom of nylon slide block body 1 is stuck in the side of telescopic boom 2, is fixed on telescopic boom 2 by slide block baffle plate 4, slide block backing plate 5 and bolt 6.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
