Description
Technical field
The present invention relates to technical field of engineering machinery, relate in particular to a kind of walking machine bearing set.The invention still further relates to a kind of walking type construction machinery with above-mentioned walking mechanical supporting device.
Background technology
Along with the fast development of China's economic construction, construction project is on the increase, walking type construction machinery particularly concrete pump truck use more and more widely.
When the pumping operating mode, in order to guarantee the stationarity of concrete pump truck, prevent that concrete pump truck from shaking or overthrow accident, on the chassis of concrete pump truck, be provided with bearing set usually, bearing set is used to support concrete pump truck.
Bearing set generally includes supporting base and a plurality of Retractive leg, Retractive leg generally includes left front Retractive leg, right front Retractive leg, left back Retractive leg, right back Retractive leg, each Retractive leg is arranged on the described supporting base, and the external side end of each Retractive leg is equipped with supporting leg, and supporting leg can be supported in ground.When concrete pump truck was in the pumping operating mode, each Retractive leg extended the respective support position, so that concrete pump truck is supported; When concrete pump truck was in driving cycle, each Retractive leg was retracted to the position that is adjacent to supporting base, to reduce the leading dimensions of concrete pump truck.
Please referring to Fig. 1, Fig. 1 is the structural representation of a kind of representative type bearing set in the prior art.
As shown in Figure 1, this bearing set comprises supporting base 1`, four collar tube sub-assembly 2`, four Retractive leg 3`, four collar tube sub-assembly 2` are double X-type and are fixed on the supporting base 1`, being a pair of collar tube sub-assembly 2` that arranges at the diagonal angle is parallel to each other and is on the equal height, four Retractive leg 3` are set with in four collar tube sub-assembly 2`, and the outer end of each Retractive leg 3` is equipped with supporting leg 4`.
When concrete pump truck is in the pumping operating mode, four Retractive leg 3` stretch at the same time or separately, after but Retractive leg 3` extends to the vertical stretching bearing set, the supporting leg 4` perpendicular movement of Retractive leg 3` outer end is to stablizing basal plane and locking, four Retractive leg 3` form a square and support angle point, thereby the fixing concrete pump truck is so that pumpdown; After pumpdown was finished, four Retractive leg 3` finished conversion from the extended configuration to the contraction state according to opposite working process.
This bearing set needs to arrange four collar tube sub-assembly 2` on supporting base 1`, two collar tube sub-assembly 2` that the diagonal angle is arranged be arranged in parallel, because the Width space of concrete pump truck is limited, make that being set in two Retractive leg 3` that arrange at the diagonal angle is difficult to make full use of space limited on the concrete pump truck Width, simultaneously have enough spread lengths in order to guarantee, thereby cause this bearing set bigger in concrete pump truck Width occupation space, even exceed the vehicle width standard that road traffic laws and regulations is stipulated, make the use of concrete pump truck be restricted.
Therefore, how to develop a kind of little bearing set that takes up room, become the technical barrier that those skilled in the art need to be resolved hurrily.
