Summary of the invention
For above-mentioned prior art Problems existing, the invention provides the connection structure of the main string of a kind of tower crane and web member, be convenient to the connection of web member, the degree-of-difficulty factor in installation process can be reduced, flexible for installation, detachably transport simultaneously, save delivery car cost, reduce and take up an area space, improve Dispatching efficiency.
To achieve these goals, the connection structure of the main string of a kind of tower crane that the present invention adopts and web member, comprise main string and web member, web member comprises diagonal web member and crossbeam web member, the two ends of crossbeam web member are connected with the main string of both sides, one end of diagonal web member is connected with main string, removably connects between described main string and diagonal web member, crossbeam web member.
Preferably, the two ends of described diagonal web member and crossbeam web member are pinned connection form, the two ends of main string and middle part are welded with otic placode I, otic placode II respectively, and the end utilizing bearing pin to pass otic placode I or otic placode II and diagonal web member or crossbeam web member realizes the connection of main string and diagonal web member, crossbeam web member.
Preferably, otic placode I at least has two connecting bores, the end utilizing bearing pin to pass one of them connecting bore and crossbeam web member realizes the connection between main string and crossbeam web member; The end utilizing bearing pin to pass another connecting bore and diagonal web member realizes the connection between main string and diagonal web member; As required, remaining connecting bore is for adjusting the installation site of diagonal web member or crossbeam web member.
Preferably, otic placode II has a connecting bore, the end utilizing bearing pin to pass this connecting bore and crossbeam web member realizes the connection in the middle part of main string and between crossbeam web member.
Preferably, the other end of diagonal web member is connected with the otic placode on gusset plate by bearing pin.
Compared with prior art, the present invention changes main string into pinned connection with web member integrated connection mode by welding, as being welded to connect otic placode on main string, and pinned connection form is made at web member two ends, the two ends of crossbeam web member or one end of diagonal web member and main string upper ear plate pass through pinned connection, be convenient to the installation of web member, reduce the degree-of-difficulty factor in installation process, flexible for installation.During simultaneously entrucking delivery, can by main string be connected bearing pin between web member and all pull down, make web member as single object, binding delivery, saves in a large number and takes up room, saved delivery car cost, improve Dispatching efficiency.By the application of this technology, the safety in installation process and convenience can be improved preferably, reduce delivery traffic cost to a great extent simultaneously.
