Please refer to Fig. 2 A-2D, the auxiliary installation pull bar 10 of present pre-ferred embodiments comprises the first segment unit 12 and second section unit 14 that interconnect, and first segment unit 12 comprises a stock 121 and is positioned at the first connecting portion 122, second connecting portion 123 of stock 121 2 end.First connecting portion 122 is provided with axis hole 122a.Second connecting portion 123 is provided with mounting hole 123a.
Please refer to Fig. 2 E-2F, second section unit 14 comprises stock 141 and is positioned at the first connecting portion 142, second connecting portion 143 of stock 141 2 end.First connecting portion 142, second connecting portion 143 is respectively equipped with axis hole 142a, 143a.
Second connecting portion 123 of first segment unit 12 is connected by bearing pin 16 with the first connecting portion 142 of second section unit 14, and bearing pin 16 is through mounting hole 123a and axis hole 142a, and bearing pin 16 can slide in described mounting hole 123a.The diameter of axis hole 142a is slightly larger than the diameter of bearing pin 16.
Auxiliary two ends installing pull bar 10, the first connecting portion 122 of first segment unit 12 and the second connecting portion 143 of second section unit 14, be respectively used to be connected with counter-jib 30, crane arm 50.
According to the size in assembled place and the ability of crane gear during installation crane arm 50, determine that crane arm 50 is divided into how many sections and installs, certainly when various conditions permit, sections is as far as possible longer, to reduce aerial work number of times.Be installed as with crane arm 50 point of three sections the installation method that example is illustrated derrick runway girder below, its step comprises:
(1) please refer to Fig. 3 A-3C, crane arm 50 is assembled into the first sections 50a, the second sections 50b on ground and the 3rd sections 50c loading trolley 80 is installed on crane arm first sections 50a;
(2) please refer to Fig. 4, the lower boom of crane arm first sections 50a left part, to relevant position, is connected with revolving dial 22 first hinge pivotable by bearing pin by lifting crane arm first sections 50a.
(3) end of one end of auxiliary installation pull bar 10 with the top boom 52 (Fig. 7) of crane arm first sections 50a is connected, the auxiliary other end installing pull bar 10 is connected with counter-jib 30 or/and revolving dial 22, then suspension hook 200 is put down, auxiliary pull bar 10 of installing in tension, thus makes crane arm 50 be connected with the hinge eliminant of other structures to become one to be rigidly connected;
(4) the first pull bar 60a is connected between support 70 and crane arm first sections 50a;
(5) please refer to Fig. 5, lifting crane arm second sections 50b is to relevant position, and be also connected between the crane arm pull bar 60b of crane arm second sections 50b with support 70 with pinned connection, crane gear can put down suspension hook 200;
(6) the second pull bar 60b is connected between support 70 and crane arm second sections 50b;
(7) please refer to Fig. 6, crane arm the 3rd sections 50c is to relevant position in lifting, by crane arm the 3rd sections 50c and crane arm second sections 50b pinned connection good;
(8) described crane arm 50 is rotated around described first hinge, counter-jib pull bar 40 is connected on described support 70 and described counter-jib 30;
(9) naturally put down by crane arm 50, the corresponding pull bar 60b tensioning of the first pull bar 60a and other sections of crane arm 50 is to hold crane arm 50, and auxiliary pull bar 10 of installing is in relaxed state.After installation, crane arm 50 has certain upwarping (being generally about 1 °), please refer to Fig. 7, distance between the top boom 52 of crane arm first sections 50a and counter-jib 30 shortens, and again because auxiliary installation pull bar 10 is with mounting hole 123a, therefore auxiliary pull bar 10 of installing is in case of bending, the effect do not stressed, therefore do not need to remove, when removing tower machine 100, crane arm 50 can segmentedly be removed.
Be appreciated that crane arm 50 installed by application auxiliary installation pull bar 10 of the present invention, crane arm 50 also only can be divided into a sections and install.In the present embodiment, the first connecting portion 122 of first segment unit 12 and the second connecting portion 143 of second section unit 14 realize being rigidly connected with counter-jib 30, crane arm first sections 50a by bearing pin respectively.But in other embodiments, auxiliary two ends installing pull bar 10 also can realize being rigidly connected with counter-jib 30, crane arm first sections 50a by alternate manners such as flanges respectively.
Be appreciated that according to the distance of crane arm 50 to counter-jib 30, auxiliary pull bar 10 of installing also can comprise a joint or more piece.When auxiliary installation pull bar 10 is a joint, second connecting portion 123 with mounting hole 123a passes through pinned connection with counter-jib 30 or crane arm first sections 50a, thus crane arm 50 is installed when being upturned, second connecting portion 123 can bend with the junction of counter-jib 30 or crane arm first sections 50a, and auxiliary pull bar 10 of installing does not stress.
Auxiliary pull bar 10 of installing is not limited to said structure, first segment unit 12 also can all arrange mounting hole 123a by two ends, second section unit 14 also one end or two ends can arrange mounting hole 123a, and auxiliary two ends installing pull bar 10 are connected with counter-jib 30, crane arm first sections 50a respectively by bearing pin.
Auxiliary pull bar 10 segmentation installation derrick runway girder 50 of installing is adopted to have at least following advantage:
1, the segmented installation of crane arm 50, avoids disposable lifting, reduces the requirement to crane gear ability, saves mounting cost, no longer requires large assembled place and carrys out assembled crane arm 50;
2, whole machine installation is complete, crane arm 50 has certain upwarping, top boom 52 and counter-jib 30 distance of crane arm 50 shorten, again because auxiliary installation pull bar 10 is with mounting hole 123a, therefore auxiliary pull bar 10 of installing is in case of bending, the effect do not stressed, therefore do not need to remove, when removing tower machine, crane arm 50 can segmentedly be removed, and auxiliary pull bar 10 of installing is removed rear recycling.
3, providing new method for installing tower machine 100 at the water surface, having widened the scope of application of tower machine 100.
The above, only embodiments of the invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
