Abstract
The utility model relates to a guide mechanism of a telescopic arm, which comprises an outer arm and an inner arm which are square cavities. The inner arm can do flexible movement in the outer arm cavity. A pair of rollers contacted with the outer surface of the inner arm is installed on the upper portion of the front end of the outer arm, and a pair of sliding blocks contacted with the outer surface of the inner arm is respectively installed on the left side and the right side of an inner cavity at the front end of the outer arm and under the inner cavity at the front end of the outer arm. A sliding block contacted with the inner surface of the outer arm is respectively installed on the upper surface, the lower surface, the left lateral face and the right lateral face of the rear end of the inner arm, and a pair of rollers is contacted with the outer surface of the inner arm in the middle portion of the outer arm. The guide mechanism of the telescopic boom adopts the mode that the rollers are combined with the sliding blocks, ensures using functions of the prior telescopic arm, reduces the weight of the telescopic arm, and improves operation capability of the telescopic arm.
Description
Technical field
The utility model relates to a kind of telescopic boom, especially a kind of guide mechanism of telescopic boom.
Background technique
The telescopic boom guide mechanism has two kinds of forms usually; A kind of is slide block type, in outer arm front end inboard and inner arm rear end surface upper and lower, left and right two groups of slide blocks is housed respectively respectively, and this mode is applicable to bears the bigger telescopic boom of static load; But when inner arm and outer arm do relative motion; Be sliding friction between slide block and the outer arm inboard, the slide block easy abrasion, and it is difficult for adjustment.Another kind is a roller type, at the fixed arm front end roller is housed, and roller contacts with the inner arm outer surface, when telescopic boom stretches, is rolling friction between inner arm and the outer arm, very is fit to carry the telescopic boom of dynamic load, and shortcoming is that the weight of roller is bigger.
Summary of the invention
It is lighter that the technical problem that the utility model will solve provides a kind of weight, and the telescopic boom guide mechanism of being convenient to adjust.
In order to solve the problems of the technologies described above; The utility model comprises outer arm and inner arm; Inner arm can be made fore and aft motion in the outer arm inner chamber; On the outer arm front end, be symmetrically installed with first roller and second roller through eccentric pin shaft; The wheel surface of first roller and second roller contacts with the inner arm outer surface, and outer arm front end inner chamber left surface is symmetrically installed with first slide block and second slide block that contacts with the inner arm outer surface, and outer arm front end inner chamber right flank is symmetrically installed with the 3rd slide block and the Four-slider that contacts with the inner arm outer surface; Be symmetrically installed with the 5th slide block and the 6th slide block that contact with the inner arm outer surface below the outer arm front end inner chamber; Upper surface is symmetrically installed with the 7th slide block and the 8th slide block that contacts with the outer arm internal surface in the inner arm rear end, and inner arm rear end left surface is symmetrically installed with the 9th slide block and the tenth slide block that contacts with the outer arm internal surface, and inner arm rear end right flank is symmetrically installed with the 11 slide block and the 12 slide block that contacts with the outer arm internal surface; Below the outer arm middle part, be symmetrically installed with the 3rd roller and the 4th roller through eccentric pin shaft, the wheel surface of the 3rd roller and the 4th roller contacts with the inner arm outer surface.
The front end of the utility model is a roller, can regulate the distance between inner arm and the outer arm easily, and slide block is adopted in the rear end, has alleviated the weight of guide mechanism.

Embodiment
As shown in Figure 1; The utility model comprises outer arm 1 and inner arm 2; Inner arm 2 can be made fore and aft motion in outer arm 1 inner chamber; It is characterized in that; Be symmetrically installed with first roller 3 and second roller 4 through eccentric pin shaft at outer arm (1) above the front end; The wheel surface of first roller 3 and second roller 4 contacts with the inner arm outer surface, and outer arm 1 front end inner chamber left surface is symmetrically installed with first slide block 5 and second slide block 6 that contacts with inner arm 2 outer surfaces, and outer arm 1 front end inner chamber right flank is symmetrically installed with the 3rd slide block 7 and the Four-slider 8 that contacts with inner arm 2 outer surfaces; Be symmetrically installed with the 5th slide block 9 and the 6th slide block 10 that contact with the inner arm outer surface below the outer arm 1 front end inner chamber; Be symmetrically installed with the 7th slide block 11 and the 8th slide block 12 that contacts with the outer arm internal surface at inner arm 2 rear end upper surfaces, inner arm 2 rear end left surfaces are symmetrically installed with the 9th slide block 13 and the tenth slide block 14 that contacts with outer arm 1 internal surface, and inner arm 2 rear end right flanks are symmetrically installed with the 11 slide block 15 and the 12 slide block 16 that contacts with outer arm 1 internal surface; The wheel surface that below outer arm 1 middle part, is symmetrically installed with the 3rd roller 17 and the 4th roller 18, the three rollers 17 and the 4th roller 18 through eccentric pin shaft contacts with inner arm 2 outer surfaces.
Because the utility model has adopted roller according to the loading characteristic of telescopic boom at front end, guarantees that telescopic boom can bear heavier dynamic load operation, the utility model rear end adopts slide block to substitute roller, has alleviated the weight of telescopic boom, has improved the working performance of telescopic boom.
