Abstract
The utility model discloses a crane boom side clearance adjusting device comprising a cover plate, a welding backing plate, locking bolts, a side clearance slide block, a supporting plate and an adjusting bolt, wherein the cover plate and the welding backing plate welded on a boom are fixed through the locking bolts; the side clearance slide block is sealed in a side clearance of the boom under the action of the cover plate; the supporting plate is filled between the side clearance slide block and the cover plate; and the adjusting bolt is arranged on the cover plate and supports against the supporting plate. The section position of the boom can be easily adjusted through tensioning or loosening by the adjusting bolt; when the side clearance slide block is greatly worn, a worn clearance can be filled by tensioning the adjusting bolt, materials can be saved and frequently adjusting the slide block is not needed; and only four locking bolts are needed to be screwed out to dismount the cover plate and replace the slide block when the slide block is needed to be replaced, therefore, the dismounting and mounting operations are simple.
Description
Technical field
The utility model relates to the arm sideshake control apparatus that a kind of hoisting crane straight-arm hangs, and belongs to the hoisting crane production field.
Background technology
The arm that the hoisting crane straight-arm hangs is in work; Because the effect of gravity and lift heavy quality can make arm about between the space of arm and arm, tremble, and has not only increased the fugitiveness of loop wheel machine; And the arm that in telescopic boom, can wear and tear; At this moment, we need add the abrasion resistant nylon slide block in the space of arm and arm, reduce the space that can tremble between the arm and do not remove the arm that weares and teares.Its sideshake slide block is fixed on the arm in the prior art, when slider wear to a certain degree the time, just need change newly, not only waste resource, and dismounting is cumbersome.
The utility model content
To the deficiency that above-mentioned prior art exists, the utility model provides a kind of also simple crane arm sideshake control apparatus of frequent change slide block and dismounting that do not need.
The technical scheme of the utility model: a kind of crane arm sideshake control apparatus; Comprise cover plate, composition backing, lock bolt, sideshake slide block, follow block, adjusting bolt; It is characterized in that: cover plate is fixed through lock bolt with the composition backing that is welded on the arm; The sideshake slide block is closed under the effect of cover plate and composition backing in the sideshake of arm, also is lined with follow block between sideshake slide block and the cover plate, regulates the bolt setting and on the cover board and with follow block offsets.
The utility model has the advantages that: the utility model tightens and transfers pine through what regulate bolt, can regulate the sectional position of arm like a cork; When the sideshake slide block occurs than galling, tighten and regulate bolt and can replenish the wearing and tearing space, can saving in material, do not need the frequent change slide block; When needs change slide block, only need back out four lock bolts and just can pull down cover plate and change slide block, so dismounting is also very simple.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is installed in the scheme drawing on the arm head cross-sectional plane for the utility model.
Fig. 3 is installed in the scheme drawing on the arm head for the utility model.
The specific embodiment
Combine accompanying drawing at present, the utility model is further described.
Like Fig. 1, Fig. 2, shown in Figure 3; Cover plate 1 is fixing through lock bolt 3 with the composition backing 2 that is welded on the arm 7; Sideshake slide block 4 is closed in the sideshake of arm 7 under the effect of cover plate 1 and composition backing 2; Also be lined with follow block 5 between sideshake slide block 4 and the cover plate 1, adjusting bolt 6 is arranged on the cover plate 1 and with follow block 5 and offsets.
