There is stretching structure at said crossbeam two ends; Said stretching structure comprises and stretches out beam-end and in order to connecting the pars contractilis of auxiliary hoist equipment, and the registration device that said pars contractilis is positioned when being used for said pars contractilis and stretching out said beam-end and in the said crossbeam of withdrawing the time.
Preferably, said stretching structure mainly by the sleeve that is connected in said crossbeam two ends and in said sleeve flexible axle form, the part that said shaft extension goes out said sleeve forms said pars contractilis.
Preferably, a said pars contractilis end of said crossbeam dorsad is provided with the baffle plate that prevents the connecting portion slippage when being used to connect the auxiliary hoist equipment, and said baffle plate is connected with said pars contractilis through bolt.
Preferably, said pars contractilis is provided with sheath.
Preferably, said registration device mainly forms by the vertical waist shaped hole on the said sleeve with through the axle bonded assembly bolt in said waist shaped hole and the said sleeve.
Preferably, said registration device mainly by the vertical waist shaped hole on the said axle with penetrate in said sleeve and the said sleeve spool on waist shaped hole bonded assembly bolt form.
Preferably, said bolt is fixed with the vertical bearing pin of said bolt y direction through one.
Preferably, said crossbeam is connected in web member and the junction of top boom or lower boom between the lower boom.
Preferably, said crossbeam has many.
A kind of crawler crane wherein, comprises the above-mentioned arm assembly of having assisted.
The beneficial effect of technique scheme is:
The stability of complete machine when the raising crawler crane plays arm can play longer jib combination under the situation of equal capability, and simple in structure being easy to is realized.

The longitudinal profile structural representation of the crossbeam of the embodiment that Fig. 3 has assisted arm assembly for the present invention is a kind of;
Fig. 4 is the B-B cutaway view of Fig. 3;
Fig. 5 has assisted the longitudinal profile structural representation of embodiment when transportation of arm assembly for the present invention is a kind of.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further, but not as qualification of the present invention.
To shown in Figure 5, a kind of embodiment that has assisted arm assembly of the present invention wherein, comprises that two ends are individually fixed in the top boom or the crossbeam on the lower boom 1 of segmentum intercalaris both sides in the principal arm of crawler crane like Fig. 1, and crossbeam 1 axis is vertical with the chord member 2 of segmentum intercalaris in the principal arm; What adopt on the accompanying drawing is that crossbeam 1 describes with top boom bonded assembly form; There is stretching structure at crossbeam 1 two ends; Stretching structure comprises and stretches out crossbeam 1 end and in order to connecting the pars contractilis of auxiliary hoist equipment 3, and the registration device that pars contractilis is positioned when being used for pars contractilis and stretching out crossbeam 1 end and in the withdrawal crossbeam 1 time.
The principle of work of technique scheme is; The pars contractilis of the stretching structure through crossbeam 1 two ends stretches out to be realized being connected with auxiliary hoist equipment 3; Thereby help principal arm to play arm through auxiliary hoist, the raising of stability when playing arm to reach raising crawler crane principal arm.Wherein the equipment 3 of auxiliary hoist generally is a suspension hook; Suspension hook is connected with pars contractilis through steel rope or suspender belt; For this reason, a pars contractilis end of crossbeam 1 dorsad can be provided for preventing the baffle plate 11 of steel rope or suspender belt slippage, and baffle plate 11 can be connected with pars contractilis through bolt 12.Can also sheath 13 be set in pars contractilis, cause wearing and tearing to prevent steel rope or suspender belt and pars contractilis excessive friction.During the principal arm transportation, for preventing that pars contractilis from stretching out the principal arm both sides and causing danger, can be with in pars contractilis retraction crossbeam 1 end, to guarantee the transportation width of principal arm.
On the technique scheme basis, further, stretching structure can be mainly by the sleeve 14 that is connected in crossbeam 1 two ends and in sleeve 14 in flexible axle 15 form, spools 15 stretch out the part formation pars contractilis of sleeve 14.Registration device can adopt mainly by the vertical waist shaped hole 16 on the sleeve 14 and see through waist shaped hole 16 and form with axle 15 bonded assembly bolts 17 in the sleeve 14, also can adopt mainly by vertical waist shaped hole on the axle 15 16 and the waist shaped hole 16 bonded assembly bolts 17 that penetrate on spools 15 in sleeve 14 and the sleeve 14 to form.Bolt 17 can be fixed through a bearing pin 18 vertical with bolt 17 y directions, in case the unintentional rotation of bolt 17 behind the fastening position.
On the technique scheme basis; Further; Crossbeam 1 can be connected in web member and the junction of top boom or lower boom between the lower boom, and the stability of principal arm when increasing the auxiliary hoist lifting can also realize that many auxiliary hoists have assisted arm through many crossbeams 1 are set.
Also comprise a kind of crawler crane in the embodiments of the invention, wherein, comprise the above-mentioned arm assembly of having assisted.
The above is merely preferred embodiment of the present invention; Be not so limit embodiment of the present invention and protection domain; To those skilled in the art; That should recognize that all utilizations specification sheets of the present invention and diagramatic content done is equal to replacement and the resulting scheme of conspicuous variation, all should be included in protection scope of the present invention.
