Abstract
The invention discloses a tower top and upper supporting base connecting structure of a tower crane. The connecting structure comprises a double-hole type connecting plate (2-1) located at the lower end of a main chord of a tower top (2), and a double-hole type positioning plate (1-1) located above an upper supporting base (1). Two round holes used for fixation are formed in the central line of the double-hole type connecting plate (2-1). Likewise, two round holes are formed in the double-hole type positioning plate (1-1). The double-hole type connecting plate (2-1) and the double-hole type positioning plate (1-1) are matched and positioned through a positioning pin (1-2). According to the connecting structure, the tower top and the upper supporting base of the tower crane can be positioned, mounted and fixed rapidly, conveniently, accurately and steadily; and pin shaft displacement is avoided, the product safety is improved, the processing cost is reduced, and the connecting structure has the advantages of being convenient and precise in mounting, simple and attractive in structure and the like.

There are raising, luffing, revolution and walking four parts in operating mechanism；
Electrical system includes motor, controller, power distribution cabinet, connection line, signal and illuminator etc..
In existing design in the welding of upper bracket structural member upper surface shown in connection otic placode 1.1(Fig. 1), at tower top main string end
Shown in the lower connection otic placode 2.1(Fig. 2 of portion's welding), by board-like otic placode, single hole pin shaft connected, lead to the structure of this kind of form multiple
Miscellaneous, manufacturing procedure complication, high cost, connection required precision are high, and the easy play of bearing pin, if otic placode is welded with deviation, lead
Bearing pin is caused can not quickly effectively connection to complete.
Content of the invention
The problem existing for above-mentioned prior art, the present invention provides a kind of derrick crane tower top to be connected knot with upper bracket
Structure, is capable of that tower top and upper bracket are quick, accurate strong fix is installed, fixing.
To achieve these goals, the technical solution used in the present invention is: a kind of derrick crane tower top is with upper bracket even
Access node structure, it includes:
Ditrysian type connecting plate positioned at tower top main string lower end and the ditrysian type location-plate above upper bracket；
Have two on the described centrage of ditrysian type connecting plate for fixing circular hole, equally open on ditrysian type location-plate
There are two circular holes, ditrysian type connecting plate is mated with ditrysian type location-plate and utilizes positioning finger setting, and then makes derrick crane tower
Top and upper bracket realize quick, be accurately positioned installations, fix.
The ditrysian type connecting plate both sides of the main string lower end of described tower top are additionally provided with polylith reinforcement.
The size of described ditrysian type connecting plate and ditrysian type location-plate, in the same size to mate.
Described ditrysian type connecting plate is rectangle or square round shape with ditrysian type positioning plate shape.
The present invention is fixed by the ditrysian type connecting plate positioned at tower top main string lower end and the ditrysian type above upper bracket
Position plate be mutually matched and using alignment pin realize derrick crane tower top and upper bracket realize quick, accurate strong fix install,
Fixing；Thus avoiding bearing pin play, improving Product Safety, decrease processing cost, have that install convenient is accurate, structure is simple
The advantages of easily attractive in appearance.
