Abstract
The invention discloses a tower top assembly of a tower crane. The tower top assembly comprises a tower top and a standard knot connected with the bottom of the tower top, and is characterized in that the tower top and the standard knot are welded into a whole, and a ladder is arranged at the side of the tower top in a welding way; and a plurality of fences which are arranged at intervals are arranged at the side of the ladder in a welding way. The tower top assembly provided by the invention has the advantages that the tower top and the standard knot are welded into a whole instead of originally connecting the two parts into a whole by pin shafts, so that the link of pin shaft installation in the installation process is reduced, the phenomenon of pin hole wear is better avoided, and the service reliability is stronger; and the fences at the side of the ladder are arranged at intervals to play a protective role and also reduce the overall weight of the tower crane.
Description
Technical field
The present invention relates to a kind of assembly, be specifically related to a kind of tower machine cat head assembly, belong to hoisting crane and make the field.
Background technology
With reference to Fig. 1, tower machine cat head assembly comprises: cat head 101, and the standard knot 102 that is connected with cat head 101 bottoms.In existing tower machine cat head assembly, cat head 101 all is formed with pin-and-hole 103 with the junction of standard knot 102, the two is to connect into an integral body by the bearing pin that passes pin-and-hole, this has just increased a field erected link, in addition, in the use procedure, wear phenomenon easily appears in pin-and-hole, not only affect the normal operation of tower machine, and had certain potential safety hazard.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of tower machine cat head assembly that reduces installation process, avoids pin-and-hole wear phenomenon and reliability of service to strengthen.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of tower machine cat head assembly comprises: cat head, the standard knot with the cat head bottom is connected is characterized in that aforementioned cat head and standard knot are integrally welded.
Aforesaid tower machine cat head assembly is characterized in that, is welded with gusset between aforementioned cat head and the standard knot.
Aforesaid tower machine cat head assembly is characterized in that the side of aforementioned cat head is welded with ladder.
Aforesaid tower machine cat head assembly is characterized in that the side of aforementioned ladder is welded with some guardrails.
Aforesaid tower machine cat head assembly is characterized in that, aforementioned guardrail interval arranges.
Usefulness of the present invention is: cat head and standard knot is integrally welded, and replace original two parts and connected into integral body by bearing pin, reduced the link that bearing pin is installed in the installation process, more avoided the pin-and-hole wear phenomenon, its reliability of service is stronger; The guardrail interval of ladder side arranges, and has both played protective action, has alleviated again the weight of tower machine integral body.
Description of drawings
Fig. 1 is the structural representation of existing tower machine cat head assembly;
Fig. 2 is the structural representation of a specific embodiment of tower machine cat head assembly of the present invention.
The implication of Reference numeral among the figure: 101-cat head, 102-standard knot, 103-pin-and-hole, 201-cat head, 202-standard knot, 203-gusset, 204-ladder, 205-guardrail.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
With reference to Fig. 2, tower machine cat head assembly of the present invention comprises: cat head 201 and the standard knot 202 that is connected with cat head 201 bottoms, wherein cat head 201 is integrally welded with standard knot 202.
In the present invention, cat head 201 adopts welding manner to be connected with standard knot 202, has replaced original two parts and has connected into integral body by bearing pin, has reduced the link that bearing pin is installed in the installation process, has more avoided the pin-and-hole wear phenomenon, and its reliability of service is stronger.
As a kind of preferred scheme, be welded with gusset 203 between cat head 201 and the standard knot 202, play the effect of strengthening cat head 201 and standard knot 202 junction intensity, guaranteed the steadiness of cat head assembly.
In order to make things convenient for aloft work, the side of cat head 201 is welded with ladder 204.
As a kind of preferred scheme, the side of ladder 204 is welded with some guardrails 205, plays good protective action.
More preferably, guardrail 205 intervals arrange, and have effectively alleviated the weight of ladder 204, thereby have effectively alleviated the weight of tower machine integral body.
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.
