The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
According to an aspect of the present utility model, as shown in Figure 3 and Figure 4, a kind of fixed supporting leg is provided, comprise the lower cover 1 that is positioned at fixed supporting leg bottom and the riser 5 that is welded on the Width both sides of lower cover 1, wherein, riser 5 is from lower cover 1 to downward-extension, and lower cover 1 and riser 5 has reinforcement 8 between the part of downward-extension, and lower cover 1, riser 5 and reinforcement 8 threes form open space and wherein, brace panel can be straight plate, but be not limited to straight plate, the plate of other shapes is also fine, only otherwise can make lower cover 1, riser 5 and reinforcement 8 threes form the space of sealing, and on brace panel, can also offer lightening hole 6 to make integral structure lighter, and offering of lightening hole 6 should be take the normal working strength of assurance brace panel as basis, otherwise, can offer, this design falls into protection domain of the present utility model equally.
As mentioned above, due to reinforcement 8 multiple brace panels that are space, and lower cover 1, riser 5 and reinforcement 8 threes form open space, therefore very convenient being connected of brace panel and lower cover 1 and riser 5, thus the quality of connection can be guaranteed, improve the intensity of this fixed supporting leg, especially when brace panel and lower cover 1 and riser 5 weld, can guarantee welding quality, and be beneficial to detection weld seam, greatly improve intensity and the security and stability of this fixed supporting leg.
According to embodiment of the present utility model, as shown in Figure 3 and Figure 4, preferably, between a part for a side of lower cover 1 and reinforcement 8, also there is backing plate 7, backing plate 7 welds with reinforcement 8, lower cover 1 and riser 5 simultaneously.Like this, when the fixed supporting leg that provides when the utility model is stressed, load not only can be delivered on riser 5 by the weld seam between aforesaid lower cover 1 and riser 5 and between riser 5 and reinforcement 8, part load can also be shared by backing plate 7, thereby further makes the transmission of load more even.In addition, the quantity of backing plate 7 can be two, and the two ends that are arranged opposite to each other at the Width of lower cover 1 are so that structure is more neat, thereby it is more even to make load distribute, but be not limited to this, for example a part for the opposite side of lower cover 1 also can correspondingly be provided with two backing plates 7.Moreover the same backing plate 7 that can be provided with in the position corresponding with backing plate 7 of the opposite side of lower cover 1 is to guarantee the local stiffness of weld.
Particularly, still referring to Fig. 3 and Fig. 4, reinforcement 8 can comprise the first brace panel 3, the second brace panel 2 and the 3rd brace panel 4, the first brace panel 3 can be positioned at the middle part of lower cover 1 length direction, and the second brace panel 2 and the 3rd brace panel 4 can be arranged on the spacing equating the both sides of the first brace panel 3 along described lower cover 1 length direction.But the utility model is obviously not limited to this, can according to actual needs, change position of weld and the quantity of the included brace panel of reinforcement 8.
In addition, this fixed supporting leg also comprises upper cover plate 9, and its upper cover plate 9, lower cover 1 have surrounded fixed supporting leg casing jointly with riser 5, so that movable supporting legs (not shown) can be moved therein.Because each plate and the utility model point of the present utility model of other composition fixed supporting legs are irrelevant, so locate to have omitted description of them.Because described fixed supporting leg comprises the fixed supporting leg that the utility model provides, therefore when movable supporting legs is stressed, described fixed supporting leg is bearing load uniformly, makes weld cracking risk less, therefore reliable according to fixed supporting leg more stable quality of the present utility model.
According to another aspect of the present utility model, a kind of hoisting crane is provided, comprise hoisting crane underframe, wherein, described hoisting crane underframe is connected with the fixed supporting leg described in technique scheme.Like this, by movable supporting legs from according to fixed supporting leg of the present utility model, stretch out and movable supporting legs the landing of bracing or strutting arrangement of itself installing, can realize the support to hoisting crane.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive 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.
It should be noted that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
