Abstract
The invention discloses a tower crane standard knot. The tower crane standard knot comprises main chords, web members, connecting sleeves and connecting bolt pairs, and is characterized in that the connecting sleeves are arranged at the outer sides of the main chords in a welding way, and each end of upper and lower ends of each main chord is respectively welded with two connecting sleeves; a diagonal cross beam is arranged between the two main chords positioned on a diagonal in a welding way, and a buffer platform is arranged on a plane of the diagonal cross beam in a welding way; and a ladder is arranged between upper and lower diagonal cross beams in a welding way. The tower crane standard knot provided by the invention has the advantages that the connecting sleeves are arranged at the outer sides of the main chords in a welding way, so that the connecting bolt pairs are arranged at the periphery of the standard knot, and thus the action space is full, and the pre-tightening force ensuring performance of the connecting bolt pairs is good; and each main chord is welded with four connecting sleeves, i.e., four connecting bolt pairs are installed, so that the specification of the high strength connecting bolt pairs can be reduced, the required pre-tightening torque is reduced accordingly, and the installation is more labor-saving.
Description
Technical field
The present invention relates to a kind of tower machine standard knot, belong to hoisting crane and make the field.
Background technology
Tower machine standard knot plays an important role in the mechanical equipments such as hoisting crane, tower wagon, elevator, and a good standard knot can not only improve the stability of these heavy-duty machines, and has promoted safety performance, flexibility ratio and the work efficiency of complete machine.
Existing tower machine standard knot, with reference to Fig. 1, tie bolt pair 101 on it is arranged on the inside of standard knot, because the secondary specification of high strength bolt is larger, needed prefastening torque is also just larger, and working space is relatively narrow, and the bolt pair predetermincd tension guarantees difficulty, thereby the stability of heavy-duty machine is difficult to be effectively guaranteed.
Summary of the invention
Be to solve the deficiencies in the prior art, the object of the present invention is to provide a kind of easy for installation, tower machine standard knot that bolt pair predetermincd tension guaranteed performance is good.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of tower machine standard knot comprises: main chord, web member, adapter sleeve and tie bolt are secondary, it is characterized in that, aforementioned adapter sleeve is welded on the outside of main chord, and the every end in up and down two ends of main chord welds 2 adapter sleeves.
Aforesaid tower machine standard knot is characterized in that, is welded with horizontally disposed diagonal angle crossbeam between two main chords on the diagonal line, is welded with ladder between two diagonal angle crossbeams up and down.
Aforesaid tower machine standard knot is characterized in that, also comprises: be welded on the diagonal angle crossbeam slow platform in the plane.
Aforesaid tower machine standard knot is characterized in that aforementioned slow platform is arranged on the side of ladder.
Aforesaid tower machine standard knot is characterized in that aforementioned slow platform is netted.
Usefulness of the present invention is: adapter sleeve is welded on the outside of main chord, thereby it is peripheral that the tie bolt pair has been arranged on standard knot, action space is abundant, and the secondary predetermincd tension guaranteed performance of tie bolt is good; 4 adapter sleeves of welding are namely installed 4 tie bolt pairs, thereby can be reduced the specification of high strength tie bolt pair on each main chord, and required prefastening torque is corresponding reducing also, installs comparatively laborsaving; Slow platform not only provides the space of interim rest and placing articles, and net structure effectively alleviated the weight of slow platform, and is easy to install and use.

Fig. 2 is the birds-eye view of a specific embodiment of tower machine standard knot of the present invention;
Fig. 3 is the lateral plan of the tower machine standard knot among Fig. 2;
Fig. 4 is the local enlarged diagram of the tower machine standard knot among Fig. 3.
The implication of Reference numeral among the figure: the 101-tie bolt is secondary, the 201-main chord, and the 202-adapter sleeve, the 203-web member, the 204-tie bolt is secondary, 205-diagonal angle crossbeam, the 206-ladder, 207-delays platform.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
With reference to Fig. 2 to Fig. 4, tower machine standard knot of the present invention comprises: main chord 201, web member 203, adapter sleeve 202, and tie bolt pair 204.Wherein, adapter sleeve 202 is welded on the outside of main chord 201, and the every end in up and down two ends of main chord 201 welds 2 adapter sleeves 202.
Tower machine standard knot of the present invention is welded on the design in the outside of main chord 201 owing to adopting with adapter sleeve 202, thereby has reached the purpose that tie bolt pair 204 is arranged on the standard knot periphery, and action space is abundant, and the secondary 204 predetermincd tension guaranteed performances of tie bolt are good; In addition, 4 adapter sleeves 202 of welding are namely installed 4 tie bolt pairs 204, thereby can be reduced the specification of high strength tie bolt pair 204 on each main chord 201, and required prefastening torque is corresponding reducing also, installs comparatively laborsaving.
As a kind of preferred scheme, between two main chords 201 on the diagonal line, be welded with horizontally disposed diagonal angle crossbeam 205, and be welded with ladder 206 between two diagonal angle crossbeams 205 up and down.
More preferably, be welded with slow platform 207 on the plane at diagonal angle crossbeam 205 places.Slow platform 207 is used for interim the rest and placing articles.
For avoiding slow platform 207 to take than large space, affect the normal use of ladder 206, slow platform 207 is arranged on the side of ladder 206.
More preferably, slow platform 207 is netted, has effectively alleviated the weight of slow platform, has both made things convenient for installation, has made things convenient for again use.
Need to prove, above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
