More specifically, boom device comprises six joint jibs.When boom device was in folded state, first segment jib 1 to the 3rd joint jib 3 was folded into R shape type.Wherein, the 3rd joint jib 3 is the jib that turns round.That is, in top view or upward view when boom device is in folded state, head end and the tail end of the 3rd joint jib 3 have certain interval.Like this, can make the folding position and the 4th of first segment jib 1 and second section jib 2 save the later folding position in the vertical direction staggered positions that respectively saves jib of jib 4, to avoid interfering and realizing rational foldable integral shape.The 4th joint jib 4 is folded to the top of the 3rd joint jib 3, and the 3rd joint jib 3 to the 6th joint jibs 6 are folded into Z-shaped.Thereby for the cloth flexibility that the joint number that increases jib in limited folding space improves boom device, the 5th joint jib 5 and the 6th joint jib 6 can be arranged in the same direction in turn.Should be appreciated that, description herein is to illustrate that exemplarily the technical solution of the utility model as purpose, should not be construed as restriction of the present utility model.Boom device of the present utility model can comprise that also the jib of other joint numbers and boom device can otherwise fold.
In more detail, according to embodiment of the present utility model, minor details jib (i.e. the 6th joint jib 6) comprises the first segmentation 61 and the second segmentation 62.Wherein, the tail end of the first segmentation 61 and the 5th joint jib is hinged, and the second segmentation 62 removably is connected with the first segmentation 61.Removably connecting and can be accomplished in several ways between the first segmentation 61 and the second segmentation 62, such as but not limited to, connect by bearing pin 64, bolt or clamp.
Further, according to embodiment of the present utility model, boom device also comprises for the standby auxiliary 63 of replacing the second segmentation 62.After the second segmentation 62 is disassembled from the first segmentation 61, standby auxiliary 63 can be connected in the first segmentation 61.According to embodiment of the present utility model, standby auxiliary 63 can be accomplished in several ways with being connected of the first segmentation 61, such as but not limited to, connect by bearing pin 64, bolt or clamp.Should be appreciated that, when the connected mode of the connected mode of standby auxiliary 63 and the first segmentation 61 and the second segmentation 62 and the first segmentation 61 adopts same connected mode, be conducive to simplified structure.For example, as shown in Figure 5, be connected via bearing pin 64 between standby auxiliary 63 and the first segmentation 61.By the connecting portion of the first segmentation 61, the second segmentation 62 and standby auxiliary 63 is arranged to universal architecture, can realize also being connected via bearing pin 64 between the second segmentation 62 and the first segmentation 61.
In addition, be fixed with carrier pipe on boom device, carrier pipe is followed and is respectively saved jib and move together, thereby with the position of concrete conveyance to appointment.According to embodiment of the present utility model, all be connected with the carrier pipe terminal on the second segmentation 62 and standby auxiliary 63.And more preferably, the carrier pipe terminal that is connected in the second segmentation 62 is general part with the carrier pipe terminal that is connected on standby auxiliary 63.Wherein, the carrier pipe terminal can be connected to other carrier pipes that respectively save on jib and removably be connected.This removably connects and can be accomplished in several ways, such as but not limited to, be threaded, buckle connection etc.According to embodiment of the present utility model, removably be connected by pipe clamp between carrier pipe terminal and carrier pipe, to improve the reliability that connects.
To Fig. 5, according to embodiment of the present utility model, the brachium of standby auxiliary 63 is longer than the brachium of the second segmentation 62 with reference to figure 3 in continuation.Like this, when using standby auxiliary 63 to replace the second segmentation 62, can effectively increase the spread length of boom device.And, because the length of standby jib 63 arranges very flexibly, therefore can also further change by the length that changes standby auxiliary 63 spread length of boom device.When boom device is in folded state, the second segmentation 62 can be connected in the first segmentation 61, to save folding space.When boom device is in job state, can not satisfy the operation needs if the second segmentation 62 is connected to the total length of formed boom device in the first segmentation 61, can use standby jib 63 to replace the second segmentation 62, thereby increase the spread length of boom device.
In more detail, according to embodiment of the present utility model, standby auxiliary 63 comprises the more piece secondary arm frame.These more piece secondary arm frame head and the tail link together in turn.And each saves connection between secondary arm frame and is and removably connects.Like this, can decide according to concrete operating mode the total length of standby jib 63, and then change the total length of boom device by the total length that changes standby jib 63.Each saves removably connecting between secondary arm frame and can be accomplished in several ways, such as but not limited to connecting by bearing pin, bolt or clamp.
Further, according to embodiment of the present utility model, can angularly arrange between the two adjacent joint secondary arm frames in the more piece secondary arm frame.Like this, can decide according to concrete operating mode the angle that respectively saves between secondary arm frame, and then the cloth flexibility that improves boom device by the global shape that changes standby auxiliary 63.
Due between the first segmentation 61 and the second segmentation 62, between the first segmentation 61 and standby auxiliary 63 and respectively saving between secondary arm frame of standby auxiliary 63 be all to be connected by simple demountable structure, drive unit is not set, therefore, of the present utility model simple in structure, be easy to realize.
On the other hand, the utility model also provides a kind of engineering machinery, and this project machinery comprises turntable.Be provided with above-mentioned boom device on turntable.Wherein, this project machinery comprises concrete mixer.
Below describe by reference to the accompanying drawings preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment in reconcilable situation, can make up by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible combinations.
