The specific embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment in the utility model can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Referring to figs. 1 through Fig. 3.
First aspect the invention discloses the auxiliary bracing or strutting arrangement of a kind of pump truck two arms, comprising: the first supporter 1, the second supporter 6 and buffering supporter 2; Be provided with supporting plane 21 above the buffering supporter 2, an end and first supporter 1 of buffering supporter 2 are rotationally connected; The other end and second supporter 6 of buffering supporter 2 are rotationally connected, and the pivot center that two places are rotationally connected is on the same straight line.
In the present embodiment, because the buffering supporter is rotationally connected with the first supporter and the second supporter respectively, therefore, buffering stand can rotate with respect to the first supporter and the second supporter, the angle of supporting plane can be adjusted automatically, regain the angle variation to adapt to jib foozle and jib, the supporting plane of buffering supporter can keep contacting support with jib formation face, better plays the effect of supplemental support.
During enforcement, an end and first supporter 1 of the buffering supporter 2 in the auxiliary bracing or strutting arrangement of pump truck two arms are rotationally connected by the first bearing pin 5; The other end and second supporter 6 of buffering supporter 2 are rotationally connected by the second bearing pin 10.And the first bearing pin 5 can also further prevent getting loose of bearing pin 5 by cottor pin 4.In like manner, the second bearing pin 10 also can further prevent from getting loose by cottor pin.
Need to prove that this bearing pin connects a kind of form that only is rotationally connected, other can realize cushioning mechanism that supporter 2 is rotationally connected with respect to the first supporter 1 and the second supporter 6 all within protection domain of the present utility model.
And, further preferably, can also be provided with baffle plate 9 at the first supporter 1 and the second supporter 6, these baffle plate 9 usefulness with cushion supporter 2 cooperate to stop the buffering supporter 2 excessively overturn.
Referring again to Fig. 1, the auxiliary bracing or strutting arrangement of pump truck two arms also comprises the cushion pad 3 on the supporting plane 21 that is arranged at buffering supporter 2.Cushion pad 3 contact surfaces are large, and force-bearing situation is good, when supporting arm frame 7, can improve application life, better play cushioning effect.
More preferred a kind of mode is, buffering supporter 2 is provided with the mounting hole (not shown), and securing member passes mounting hole cushion pad 3 and supporter 2 are fastenedly connected.After buffering stand 2 has mounting hole, 3 assemblings that can realize horizontal position adjustment of cushion pad, in this way, to satisfy the variation of two arm horizontal levels.
In addition, the first supporter 1 can also comprise the first supporting body and first fold turn of bilge, preferably, and the bending part of the moulding that the first supporting body and first fold turn of bilge are integrated; The second supporter 6 comprises the second supporting body and the second bending part, the bending part of the moulding that the second supporting body and the second bending part are integrated.Adopt the benefit of integrated bending part to be, can reduce number of spare parts and welding, and gain in strength.For the first supporter 1 and the second supporter 6, bending part can be inside, also can be outside.The utility model is not done restriction at this.Preferably, in the specific implementation, the first supporter 1, the second supporter 6 and buffering supporter 2 are preferably box structure, U-steel or rectangle steel structure, and that such structure has is lightweight, weld seam is few, the intensity advantages of higher.
The auxiliary bracing or strutting arrangement of above-mentioned pump truck two arms can be arranged on Secondary Beam For Concrete Pump Truck or the diagonal member 8.With reference to Fig. 3, the α angle [0 °, 90 °) between.When α was 0 °, the auxiliary bracing or strutting arrangement of pump truck two arms dropped on the auxiliary girder, when α between (0 °, 90 °) time, the auxiliary bracing or strutting arrangement of pump truck two arms drops on the diagonal member.Thereby because the left and right sides, pump truck chassis crossbeam lateral dimension is relatively fixing, and auxiliary girder and diagonal member will be fixed on the crossbeam of the left and right sides, pump truck chassis, therefore can realize general.In addition, when the auxiliary bracing or strutting arrangement of pump truck two arms is not located on auxiliary girder or the diagonal member, and when being provided in a side of on the capstan head seat, buffering stand 2 lateral attitudes can be reduced to the position close with cushion pad 3, the first supporter 1, the second supporter 6 height step-downs can reduce weight simultaneously, save cost.
To sum up, the angle of the auxiliary bracing or strutting arrangement of the utility model pump truck two arms and the contacted supporting plane of jib can be adjusted automatically, therefore, can adapt to jib foozle and jib and regain the angle variation, keep contacting support with jib formation face, better play the effect of supplemental support.
On the other hand, the utility model also provides a kind of solidifying native pump truck, on Secondary Beam For Concrete Pump Truck, diagonal member or capstan head seat, is provided with the auxiliary bracing or strutting arrangement of aforesaid pump truck two arms.Because the structure of the auxiliary bracing or strutting arrangement of pump truck two arms has been done detailed explanation, the utility model does not repeat them here, and relevant part gets final product with reference to above-mentioned explanation.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
