Technical field
The utility model relates to engineering machinery field, is specifically related to a kind of holder anti-indigenous equipment of sprocket wheel and crawler crane.
Background technology
For medium and small tonnage caterpiller crane, during track frame design, its height need meet the demand as far as possible reducing complete machine height, to ensure the stability of complete machine, as shown in Figure 1; And must ensure there are enough gaps between track frame 6 and turntable nadir, when doing 360 ° of revolutions with 5 (the comprising all parts of turntable and upper assembling thereof) that ensured to get on the bus relative to crawler body, turntable and on fill parts and do not interfere with track frame 6.
Track frame is also known as track beam, track unit.As shown in Figure 2, track frame 6 is generally made up of Side frame 8, actuating device 7 (comprising traveling gear, drive wheel), caterpillar wheel 9, holder sprocket wheel 11, track adjusting wheel 12, caterpillar block 10.The parts affecting track frame 6 height mainly contain caterpillar block 10 height, caterpillar wheel 9 setting height(from bottom), Side frame 8 height, holder sprocket wheel 11 setting height(from bottom).Wherein caterpillar block 10, Side frame 8, caterpillar wheel 9 setting height(from bottom) all can involve the carrying problem of complete machine and can not arbitrarily reduce, and the height dimension of larger adjusting range can be had to be exactly the setting height(from bottom) of holding in the palm sprocket wheel 11.So, on medium and small volume production usually by a part for holder sprocket wheel 11 even majority hide in Side frame 8, as shown in Figure 3.This just makes crawler crane at muddy Ground Operation, and when earth is involved in holder sprocket wheel 11, earth directly enters Side frame 8.Although also have corresponding hole below general holder sprocket wheel 11, because the earth amount of bleeding is large, wet again and glue, Side frame 8 inside will soon be blocked.Because earth is deposited in Side frame 8 box inside, so cleaning work is difficult to carry out.The duration such as generally to only have terminate, when the repairing place of user got back to by vehicle, just can open crawler belt, holder sprocket wheel 11 of dismantling, more carefully clear up.And at this moment often ask sprocket wheel 11 to be stuck and not turn, wearing and tearing break down, the holder sprocket wheel 11 that can only more renew.
In prior art, for enabling the dregs being involved in holder sprocket wheel 11 discharge smoothly, conventional method has two kinds, and see Fig. 4 a, Fig. 4 b and Fig. 5, wherein Fig. 4 b conceals main riser.
Method one: directly perforate on the base plate holding in the palm Side frame 8 below sprocket wheel 11, Fig. 4 a illustrates dregs cleaning eye 13, has dregs closure plate 14, want to be spilt by dregs by the hole base plate from Side frame 8 inside below holder sprocket wheel 11, as shown in figures 4 a and 4b, Fig. 4 b conceals main riser.
Method two: the bending thin plate of a welding pocket soil below holder sprocket wheel 11, in the riser of Side frame 8 and the nadir of thin plate two ends weld, stay the leakage soil hole that little respectively, dregs can be cleared up from aperture place.
Contriver finds, at least there is following problems in prior art:
