Abstract
The utility model discloses a kind of chip tower crane standard knot, including the first standard knot, the second standard knot, the 3rd standard knot, the 4th standard knot, adjacent two sides respectively set a piece of connection sheet at the top of standard knot, relative two sides set long fish platee at the top of standard knot, remaining relative two sides set short fish platee at the top of standard knot, standard knot bottom offers the connecting hole being adapted with long fish platee, short fish platee, four standard knot rectangles are placed, and two neighboring standard knot is directly connected by cross bar.The utility model causes the simple convenient transportation of standard knot and is relatively easy to when dismounting compared with prior art, reduces overall construction weight, and the structural strength and good rigidity of tower crane, wind load is small, independent fixed high；It can reliably ensure that boom end fish platee commissure is solely subjected to the effect of pulling force, and be not subjected to alternate load, improve the reliability and service life of standard knot, and then improve the service behaviour and security of tower body.
Description
Technical field
It the utility model is related to a kind of standard knot, and in particular to a kind of chip tower crane standard knot.
Background technology
Derrick crane is the conventional crane hoisting equipment of architectural engineering operation, and tower crane main part is by a section section standard
Superposition forms section from bottom to top.The docking speed of standard knot directly affects the installation rate of tower crane, and what is connected between standard knot can
The security of tower crane is directly affected by property.Large-tonnage tower crane tower body is connected using bearing pin in major part in Chinese market at present, peace
Efficiency high is filled, high-strength bolt type of attachment tensile strength is higher, and shear resistance is poor, bolt during use be present by larger shearing, even
Exist after connecing and connected not closely between main string dislocation, main chord, and influence tower crane security.
The content of the invention
In view of the above-mentioned problems of the prior art, a kind of chip tower crane standard knot of the utility model offer, convenient transport,
Installation is quick, and bearing capacity is bigger, and independent level altitude is high, and wind load resistance ability is strong.
To achieve these goals, the technical solution adopted in the utility model is：A kind of chip tower crane standard knot, including the
One standard knot, the second standard knot, the 3rd standard knot, the 4th standard knot, the adjacent two sides in standard knot top respectively set a piece of company
Contact pin, the relative two sides in standard knot top set long fish platee, and the remaining relative two sides in standard knot top set short fish
Tailgate, standard knot bottom offer the connecting hole being adapted with long fish platee, short fish platee, and four standard knot rectangles are placed, phase
Adjacent two standard knots are directly connected by cross bar.
The long fish platee of setting, short fish tail harden structure are opposite at the top of two adjacent standard knots.
Fish tail harden structure at the top of standard knot is identical with the connection pore structure of its bottom.
The utility model causes the simple convenient transportation of standard knot and is relatively easy to when dismounting compared with prior art, reduces
Overall construction weight, the structural strength and good rigidity of tower crane, wind load is small, independent fixed high；Boom end can reliably be ensured
Fish platee commissure is solely subjected to the effect of pulling force, and is not subjected to alternate load, and the utility model can effectively postpone weld seam
Fatigue failure, improve the reliability and service life of standard knot, and then improve the service behaviour and security of tower body；Installation is fast
It is prompt effective, improve maintenance staff's operating efficiency；It is simple to operate, it is convenient to promote practicality；Reasonable structural arrangement, there is higher safety can
By property.
Brief description of the drawings
Fig. 1 show the utility model top view；
Fig. 2 show the utility model front view；
In figure：1st, the first standard knot, the 2, second standard knot, the 3, the 3rd standard knot, the 4, the 4th standard knot, 5, cross bar, 6, long
Fish platee, 7, short fish platee, 8, connection sheet.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the utility model includes the first standard knot 1, the second standard knot 2, the 3rd standard knot the 3, the 4th
Standard knot 4, the adjacent two sides in standard knot top respectively set a piece of connection sheet 8, and the relative two sides in standard knot top set length
Fish platee 6, the remaining relative two sides in standard knot top set short fish platee 7, and standard knot bottom offers and long fish platee
6th, the connecting hole that short fish platee 7 is adapted, four standard knot rectangles are placed, and two neighboring standard knot is directly connected by cross bar 5.
Articulation hole high-strength bolt circulation between each connection sheet 8 is tightened by standard knot and cross bar torque spanner and reaches corresponding
Pre-fastening moment；Connected mode is connected using symmetrical fish platee with bearing pin between standard knot, and two bearing pins are arranged in right-angled intersection pattern,
Reasonable structural arrangement, there is higher security reliability.
In order to further improve the stability of the utility model connection, the long fish tail set at the top of adjacent two standard knots
Plate 6, the structure of short fish platee 7 are on the contrary, the fish tail harden structure at the top of standard knot is identical with the connection pore structure of its bottom.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Described above, preferred embodiment only of the present utility model is every according to this not to limit the utility model
Any trickle amendment, equivalent substitution and the improvement that the technical spirit of utility model is made to above example, it should be included in this
Within the protection domain of utility model technical scheme.
