The specific embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the present invention can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
Fig. 1-Fig. 8 shows the traveling gear of crawler crane and the structural representation of each parts thereof that the embodiment of the present invention provides; As Figure 1-Figure 8, the traveling gear of the present embodiment crawler crane comprises: track frame 5, caterpillar block chain 6, front driving wheel 11, rear drive sprocket 12 and reductor 8, and described in each, track frame 5 correspondences are provided with described front driving wheel 11 and rear drive sprocket 12; Described front driving wheel 11 is arranged on the front end of described track frame 5, and described rear drive sprocket 11 is arranged on the rear end of described track frame 5, described in each the described front driving wheel 11 of track frame 5 and rear drive sprocket 12 respectively with two described reductors 8 one by one corresponding driving connect.
Such scheme is by the mode that adopts front driving wheel 11, rear drive sprocket 12 to drive to every track frame 5 simultaneously, mode than tension wheel before driving by rear drive sprocket in prior art, the transmission of propulsive effort is more evenly more efficient, the structural fatigue wear phenomenon that has reduced to be caused by discontinuity equalization, thus service life of track frame 5 extended; In addition, the four wheel drive mode of two track frames 5 is than the mode of existing two-wheel drive, strong lifting walking propulsive effort and turning and the maneuverability such as climbing; Simultaneously, article two, four of track frame 5 drive wheels evenly drive, mode than existing two-wheel drive, each drive wheel in four drive wheels 1 can reduce volume, correspondingly can select reductor 9 and the less HM Hydraulic Motor of discharge capacity that moment of torsion is less, on the basis that promotes locomotor activity, reduce manufacture difficulty.
During concrete operations, front driving wheel 11, rear drive sprocket 12 can be fixed on track frame 5; Certainly can only rear drive sprocket 12 be fixed on track frame 5, front driving wheel 11 is by caterpillar block chain 6 described in tightening device tensioning, that is to say, the traveling gear of described crawler crane also comprises for making the tightening device of caterpillar block chain 6 described in front driving wheel 11 tensionings, described tightening device and described front driving wheel 11 removably connect, and are arranged on described track frame 5.Described tightening device can comprise: for the jack 7 to described front driving wheel 11 applied thrusts, described jack 7 is arranged on described track frame 5.
Preferably, consider crawler crane when walking, larger weight need to be born in front portion, and described tightening device also comprises: tension part 2, and one end of described tension part 2 and described front driving wheel 11 removably connect, and the other end is connected with described jack 7.Particularly, described tension part 2 is box-structure.This tension part 2 can conduct to the thrust of jack 7 on described front driving wheel 11 on the one hand, with caterpillar block chain 6 described in tensioning, the weight of crawler crane front portion be can also bear on the other hand, the integrally-built stability of crawler crane and fastness increased.
Preferably, one end of described tension part 2 adopts plug-in mounting mode to be connected with described front driving wheel 11, is convenient to dismounting; The other end of described tension part 2 is connected with described jack 7.
Preferably, as shown in Figure 2, the traveling gear of described crawler crane also comprises: for pad 3 and the latch 4 of fixing described tension part 2 positions; Its Intermediate gasket 3 can be structure as shown in Figure 8, particularly, pad 3 is enclosed within on tension part 2, latch 4 connecting band track framves 5 and pad 3, described jack 7 removably connects with described track frame 5, after jack 7 push-tight tension parts 2, by latch 4 and pad 3 fixed tensioning parts 2 positions, realize the adjusting of caterpillar block chain 6 amount of tension and jack 7 can be removed afterwards, at work-site, only need a jack 7 thus.
The principle of work of the traveling gear of above-mentioned crawler crane: the hydraulic efficiency pressure system of crawler crane provides hydraulic fluid pressure to drive walk motor with hydraulic pressure, and then provide enough large each self-corresponding drive wheel 1 of torque drive to rotate by reductor 8 speed changes, thereby realize crawler crane, freely walk.
The present embodiment is by replacing with drive wheel by the tension wheel of track frame front end in prior art, make crawler belt tight with less resistance transmission of drive force, the transmission of propulsive effort is more evenly more efficient, the structural fatigue wear phenomenon that has reduced to be caused by discontinuity equalization, thereby extended the service life of track frame, can select the driving reductor that moment of torsion is less simultaneously, the pressure motor of the less more economical liquid of discharge capacity and drive wheel, also strengthened the maneuverabilities such as walking, turning and climbing of crawler crane greatly; In addition, the tension part of the box that is connected with drive wheel of design is used for tensioned tracks chain, by jack and pad adjusting track chain surplus, by latch setting up piece, tightening device and track frame adopt the connecting mode of plug-in mounting, are easy to telescoping, tensioning track chain, convenient, flexible easy operating.
The present invention also provides a kind of embodiment (not shown) of crawler crane, it comprises hydraulic efficiency pressure system and walk motor with hydraulic pressure, described crawler crane is provided with the traveling gear of described crawler crane, and described walk motor with hydraulic pressure drives the reductor in described traveling gear.
Preferably, described hydraulic efficiency pressure system comprises two oil feeding lines, and two described oil feeding lines correspond to one by one for driving two walk motor with hydraulic pressure fuel feeding of described two reductors.
Because crawler crane has the corresponding technique effect of above-mentioned traveling gear, repeat no more.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
