Abstract
The utility model discloses a bushing structure of tower machine standard festival, including first, the standard festival of second, the second standard festival is located the top of first standard festival, and lower part that the upper portion of first standard festival side was fixed with first sleeve pipe, second standard festival side is fixed with the second sleeve pipe, and is first, second sheathed tube centre bore concentric, be equipped with on the first sheathed tube up end with the endocentric drum of first sleeve pipe, the drum is pegged graft in the reaming that second sleeve pipe bottom was equipped with, wear to be equipped with fastening bolt in first, the second sheathed tube centre bore. Simple structure, drum that first sleeve pipe up end was equipped with peg graft intraductally at the second cover, and drum and underreamed fits can eliminate the horizontal displacement between first, the second sleeve pipe terminal surface, and the cooperation is inseparable between, the second sleeve pipe first through guaranteeing behind the bolt fastening to improve the stability of standard festival connection.
Description
Technical field
This utility model relates to derrick crane and manufactures installing area, is specifically related to the casing-pipe connection structure of a kind of tower crane standard knot.
Background technology
In recent years, along with the rapid growth of China's economic construction, capital construction scale constantly expands, particularly being on the increase of high-building construction, and the application of derrick crane is the most extensive.The standard knot of derrick crane is to determine tower crane height, the vitals of stability, during installation, one standard knot is placed on another standard knot and makes it coordinate four sleeve pipes in face to offset, then in two adjacent sleeve pipes, wear bolt fastening, there is certain fit clearance in bolt left and right directions in upper and lower two sleeve pipes, two sleeve pipes can move by occurred level, thus cause there will be, between adjacent modular joint, the phenomenon horizontally slipped, stability and the safety of whole tower crane are poor.
Summary of the invention
The utility model discloses the casing-pipe connection structure of a kind of tower crane standard knot, simple in construction, upper and lower sleeve pipe is completely embedded reliably, is greatly improved the stability that standard knot connects.
This utility model is achieved through the following technical solutions:
The casing-pipe connection structure of tower crane standard knot, including first, second standard knot, second standard knot is positioned at the top of the first standard knot, the top of described first standard knot side is fixed with first sleeve, the bottom of the second standard knot side is fixed with the second sleeve pipe, the centre bore of described first, second sleeve pipe is concentric, the upper surface of described first sleeve is provided with the cylinder concentric with first sleeve, described cylinder is plugged in the reaming that described second sleeve bottom is provided with, and is equipped with fastening bolt in the centre bore of described first, second sleeve pipe.
The further improvement project of this utility model is, the upper surface of described first sleeve props up the lower surface of described second sleeve pipe.
The further improvement project of this utility model is, described first, second sleeve pipe is respectively welded and is fixed on described first, second standard knot.
The further improvement project of this utility model is, 1/10th of a length of described second casing length of described cylinder.
Compared to the prior art this utility model has the advantage that
This utility model simple in construction, the cylinder that first sleeve upper surface is provided with is plugged in the second sleeve pipe, the fit system of cylinder and reaming can eliminate the horizontal displacement between first, second box face, it is able to ensure that between first, second sleeve pipe cooperation after being bolted closely, thus improves stability and fixing reliability that standard knot connects.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
The casing-pipe connection structure of tower crane standard knot as shown in Figure 1, including first, second standard knot 1,2, second standard knot 2 is positioned at the top of the first standard knot 1, the top of the first standard knot 1 side is fixed with the bottom of first sleeve the 3, second standard knot 2 side and is fixed with the second sleeve pipe 4, the centre bore of first, second sleeve pipe 3,4 is concentric, the cylinder 5 concentric with first sleeve 3 it is fixed with on the upper surface of described first sleeve 3, described cylinder 5 is plugged in the reaming being provided with bottom described second sleeve pipe 4, and cylinder limits the horizontal displacement of first, second sleeve pipe.It is equipped with fastening bolt 6, for connecting first, second sleeve pipe and then fixing first, second standard knot in the centre bore of first, second sleeve pipe 3,4.
In the present embodiment, the upper surface of first sleeve 3 props up the lower surface of the second sleeve pipe 4, and first, second sleeve pipe coordinates closely, compact conformation, fixing reliable.First, second sleeve pipe 3,4 is respectively welded and is fixed on first, second standard knot 1,2；/ 10th of a length of second sleeve pipe 4 length of cylinder 5.
