Description
Technical field
The present invention relates to a kind of standard knot, particularly a kind of guiding standard knot for tower crane, belongs to crane facility field.
Background technology
In existing tower machine standard knot, bolt is relied on to connect between adjacent modular joint, because standard knot end face is without any guide piece, as shown in Figure 1, in installation process, normal appearance two joint standard knots align difficulty thus the situation causing bolt hole to misplace, often need repeatedly to dock and just can complete installation, operation is wasted time and energy, and safety is simultaneously poor.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of guiding standard knot for tower crane, the docking of two joint standard knots can be completed rapidly, be convenient to the installation of main string to dead aft just adapter sleeve bolt, significantly improve convenience and the safety of installation.
To achieve these goals, a kind of guiding standard knot for tower crane that the present invention adopts, comprise standard section main string, described standard section main string is provided with adapter sleeve, standard section main string inside is provided with upper sealing plate for waterproof and lower shrouding, also comprises the guide piece being arranged on and standard section main string being convenient to adjacent modular joint Matching installation;
Described guide piece comprises the orienting sleeve that can be arranged on main string upper end, and the cover plate for waterproof is equipped with in the upper end of orienting sleeve, and the side of orienting sleeve has the through hole be convenient to orienting sleeve plug welding process in main string.
Further, the upper end of orienting sleeve is with the tapering being convenient to dock between standard knot.
Further, orienting sleeve is fixed on the upper sealing plate in standard section main string.
Further, the upper end of orienting sleeve is welded with the cover plate of waterproof.
Further, orienting sleeve is welded on the part in standard section main string, and its surface has two symmetrical through holes.
Further, the lower end size of orienting sleeve is mated with the size in standard section main string; Be welded on the size of the main string of joint under gauge of the cover plate of orienting sleeve upper end.
Compared with existing standard knot, the invention has the beneficial effects as follows: the guide piece with installation guide function be made up of cover plate and orienting sleeve is installed in the main string of traditional standard joint, by the orienting sleeve in guide piece make the accurate internode of two feast-brand marks accurately, rapid abutting joint, main string is to the installation of dead aft just adapter sleeve bolt, greatly improve agility and the safety of installation, this guide piece structure is simple, easy to use; The cover plate on orienting sleeve surface well can play waterproof, foreign material etc. and enter main string inside simultaneously, avoids the reduction causing the standard knot life-span.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 2 and 3, a kind of guiding standard knot for tower crane, comprise standard section main string 1, described standard section main string 1 is provided with adapter sleeve 2, standard section main string 1 inside is provided with upper sealing plate 1.1 for waterproof and lower shrouding 1.2, also comprises the guide piece 3 being arranged on and standard section main string 1 being convenient to adjacent modular joint Matching installation;
Described guide piece 3 comprises the orienting sleeve 3.2 that can be arranged on main string upper end, and the cover plate 3.1 for waterproof is equipped with in the upper end of orienting sleeve 3.2, and the side of orienting sleeve 3.2 has the through hole 3.3 be convenient to orienting sleeve 3.2 plug welding process in main string.
As the further improvement of embodiment, the upper end of orienting sleeve 3.2 is with the tapering being convenient to dock between standard knot, in order to ensure the agility of docking, orienting sleeve 3.2 is designed to the tapered configuration that upper end is narrow, lower end is wide, upper standard knot during installation is accurately docked on lower standard knot by being sleeved on guide piece 3.
Orienting sleeve 3.2 is fixed on the upper sealing plate 1.1 in standard section main string 1, makes to be arranged on tight between orienting sleeve 3.2 in standard knot on string 1 and upper sealing plate 1.1, avoids there is space between the two and causing foreign material etc. to enter in orienting sleeve 3.2; And there is space between the two and can cause the integrally-built instability of standard knot, the service life of the joint that debases the standard.
As shown in Figure 4, the upper end of orienting sleeve 3.2 is welded with the cover plate 3.1 of waterproof, effectively plays waterproof and dustproof, anti-foreign material etc. and enters in orienting sleeve 3.2, effectively plays the effect of protecting standard joint, extends its service life.
Orienting sleeve 3.2 is welded on the part in standard section main string 1, and its surface has two symmetrical through holes 3.3, only need open the technological requirement that two through holes 3.3 just effectively can meet plug welding, and ensureing does not have welding bead to interfere between two joint main chord of standard sections; And the number of openings is two, avoiding reducing installation effectiveness because opening multiple through hole, having ensured the agility of installing.
The lower end size of orienting sleeve 3.2 is mated with the size in standard section main string 1, ensures firm being arranged in standard section main string 1 of orienting sleeve 3.2 energy, realizes firmly integrally-built; Be welded on the size of the main string 1 of joint under gauge of the cover plate of orienting sleeve 3.2 upper end, have and avoid because cover plate 3.1 is oversize and cause upper standard knot cannot be arranged on the generation of lower standard knot situation.
During use, as shown in Figure 5, orienting sleeve 3.2 leaves two through holes 3.3, the upper end welded cover plate 3.1 of orienting sleeve 3.2, guide piece 3 has been assembled; During installation, the lower end controlling orienting sleeve 3.2 is fixed on upper sealing plate 1.1, is taked by guide piece 3 welding process of plug welding to be arranged in standard section main string 1, to guarantee not having welding bead to interfere between two joint main chord of standard sections; Two standard knots are installed by guide piece 3.2, between the upper sealing plate 1.1 of the guide piece 3.2 after installation in standard knot in string 1 and lower shrouding 1.2.Two standard knots after alignment realize fixing by the in-built bolt of adapter sleeve 2.
