The utility model discloses a round pin axle is connected the main chord and the tenon of standard festival, and the free end of round pin axle is equipped with the recess, and the tenon adopts the jump ring to block round pin axle recess after the round pin axle is good, is equipped with the gasket in the middle of the main chord of jump ring and standard festival simultaneously, prevents to sell the epaxial drunkenness that produces after the installation.
Description
Technical Field
The utility model relates to a tenon of connection standard festival belongs to tower crane installation accessory technical field.
Background
The tower body of the tower crane generally consists of a plurality of standard sections, the stress at the joints among the standard sections of the tower body is complex in the working process, and the reliability of the connection among the standard sections has important significance. The stress between the main strings of each standard knot is mainly transmitted by the connecting part, and if the connection is unreliable, the stress has great influence on the safety of the tower crane. And the number of the installed time nodes is large at the same time, and high requirements are provided for the installation convenience and the economical efficiency of manufacturing and processing.
In the existing technical scheme, the standard section of the tower crane is connected by adopting a bolt connection (as shown in figure 1) or a pin shaft connection (as shown in figure 2). The bolt connection needs to adopt larger pretightening force, can be screwed by a special tool, and is easy to generate the condition that the stress of the bolt is uneven. The pin shaft connection is only suitable for a single-angle steel structure, and has higher requirements on the dimensional accuracy of fishplates, holes, pin shafts and the like and higher cost for ensuring the stress of the pin shafts and the convenience in installation.
Disclosure of Invention
In order to overcome the not enough of above-mentioned prior art, to the problem that above scheme exists, the utility model provides a can improve the convenience of standard festival installation and the security of use, specifically be a tenon of connecting standard festival. The inner force of the main chord member is transmitted through tenon pressure bearing and shearing, the force transmission route is simple, all connecting pieces are uniformly stressed, the axial movement of the pin shaft in the using process is prevented through the clamp spring and the gasket, and the use reliability is improved.
The utility model is realized by the following technical proposal, a tenon for connecting standard knots,
the tenon is used for connecting the upper standard section and the lower standard section which are adjacent to each other;
a plurality of through holes are formed in the tenon, and mounting through holes are formed in the standard sections corresponding to the positions of the through holes;
and the pin shaft is used for being inserted into the mounting through hole on the standard joint and the through hole on the tenon corresponding to the mounting through hole.
As a preferred scheme of the tenon of connecting standard festival: the tenon is provided with a plurality of through holes, and the through holes are divided into a first upper through hole and a second upper through hole which are used for fixedly connecting the upper standard knot and a first lower through hole and a second lower through hole which are used for fixedly connecting the lower standard knot.
As a preferred scheme of the tenon of connecting standard festival: the included angle between the center lines of the first upper through hole and the second upper through hole is in a non-coplanar vertical mode;
the included angle between the central lines of the first lower through hole and the second lower through hole is in a non-coplanar vertical mode.
As a preferred scheme of the tenon of connecting standard festival: and the free end of the pin shaft is also provided with a gasket and a clamp spring.
The utility model discloses the advantage as follows:
1. the force transmission route is simple, all the connecting pieces are stressed uniformly, and the connection reliability is ensured;
2. the pin shaft prevents axial movement and ensures use safety.
3. Tenon and round pin axle structural style are simple, and jump ring, gasket are the standard part, and the processing purchase of being convenient for reduces manufacturing cost.
